AB These India is suffering from the problem of meeting peak demand of about 12 %. Demand side management is one of the efficient methods to solve this problem. It can reduce the peak load and thereby facilitate peak load management, smoother grid operation and economic benefits. Demand side management can be started from consumer side by using intelligent loads, both for industries and household. This paper describes an efficient DSM strategy and a more efficient algorithm for that. Parameter selection and observation is also important in facilitating DSM. Here the approach used is based on time, system voltage, frequency and need of operation of load. Also describes the design, simulation and experimental prototype verification of Automatic demand side managing device using AT89s51 microcontroller for managing the pump load. Simulation is conducted in Matlab-simulink platform.

AB For all high-performance detectors, well understood optical test systems are needed for precise characterisation and calibration. A cryogenic variable temperature blackbody load has been developed to test the optical efficiencies of ultra-low-noise (NEP similar to 10(-19) WHz(-1/2)) Transition Edge Sensors for space science. The few-mode, partially coherent illumination conditions of the measurement system are engineered to be precisely the same as those of the telescope. We have used a SPICA/SAFARI-like telescope/detector for demonstration purposes. The essential difference between the test system and an equivalent representation of the telescope's optics is that the telescope has a lens of effective focal length f, but the test system does not. A key part of our analysis is to describe behaviour in terms of the optical modes of the test system, as distinct from the optical modes of the detector under test. In the paper we describe the analysis of the test assembly in terms of signal power, background power and photon noise.

AB NIST has developed a new channel sounder design specifically to support radio-channel model development for 5G millimeter-wave mobile communications. Design elements include 40 GB/s real-time sampling; an electronically switched, high-gain, directional receive antenna array covering the upper hemisphere; and automated mobile operations. These features allow measurement of calibrated received signal strength and the spatio-temporal channel response for both indoor and outdoor environments under mobile conditions. An 83 GHz system is described in this paper while 28 GHz and 60 GHz systems, in process, have similar capabilities. To our knowledge, this work contributes the first channel sounder which is capable of broadband, 3D, mobile measurements at millimeter-wave frequencies.

AB Previous testing has shown that measuring a device's susceptibility to a radiated, broadband signal can present a different set of challenges than those faced when testing with a narrow-band signal. Decisions ranging from choosing a measurement facility to defining the measurement of the radiated electric field to defining when a DUT has failed can all have an impact on the final test results. In previous publications we've outlined these challenges via the use of experiments involving cable communications equipment and its susceptibility (or lack thereof) to radiated LTE signals. Here, we continue with those experiments, but shift the focus to proposing solutions to these questions. We discuss these solutions in a general sense, with hopes that they will encourage discussion in the community.

AB In recent years, automatic visual inspection system has become useful tool in industrial process. The citrus fruit sorting and grading process has now been completely automated with the exception of the final stage of classification concerned with visual inspection. Due to the growing demand of quality citrus fruit, an automated and reliable identification and classification mechanism in order to handle the bulk of data is implemented. Human vision sometimes leads to mismatch between the fruits. Using machine vision system, it will be simple to reduce human effort and achieve a better output. The objective of this project is to assess the fruit by color grading. In this paper we describe an integrated system developed for the sorting on citrus fruit and for the color grading of the defected fruits. The result suggests that the performance is adequate to provide the basis for a viable commercial visual inspection system. The following project aims at implementing such an automated system using image processing with images of citrus fruit as a basis of classification depending on its color. The goal of the inspection is not to give a statistical analysis of the production but to classify every citrus fruit into quality constant batches.

AB The NIST neutron imaging program will build a new imaging instrument in the NCNR guide hall at the end of the neutron guide NG-6, beginning operation in summer of 2015. The NG-6 guide has a spectrum that is strongly peaked at a neutron wavelength of 0.5 nm, with a fluence rate of 2 x 10(9) cm(-2) s(-1) before a bismuth filter that is cooled by liquid nitrogen. The instrument will be developed in a phased manner and with an emphasis on maintaining a flexible space to conduct experiments and test new instrument concepts. In the initial phase of the instrument, the available space will permit a flight path of about 9 m, and will provide a platform for standard neutron radiography and tomography, wavelength selective imaging with a double crystal monochromator, and phase imaging based on a Talbot-Lau interferometer. The novel feature of the instrument will be the incorporation of Wolter optics to create a neutron microscope. Initially, prototype optics will be used in the microscope configuration to assess optic characteristics and image acquisition techniques. In the final form, the microscope will enable users to acquire images with similar to 10 mu m resolution 10-100x faster than current practice, and with a 10x magnifying optic to acquire images with similar to 1 mu m spatial resolution with image acquisition time similar to that for current images with similar to 10 mu m resolution.

AB Enhanced geothermal systems seek to expand the potential for geothermal energy by engineering heat exchange systems within the earth. A neutron radiography imaging method has been developed for the study of fluid flow through rock under environmental conditions found in enhanced geothermal energy systems. For this method, a pressure vessel suitable for neutron radiography was designed and fabricated, modifications to imaging instrument setups were tested, multiple contrast agents were tested, and algorithms developed for tracking of flow. The method has shown success for tracking of single phase flow through a manufactured crack in a 3.81 cm (1.5 inch) diameter core within a pressure vessel capable of confinement up to 69 MPa (10,000 psi) using a particle tracking approach with bubbles of fluorocarbon-based fluid as the "particles" and imaging with 10 ms exposures.

AB Air entrainment is commonly added to concrete to help in reducing the potential for freeze thaw damage. It is hypothesized that the entrained air voids remain unsaturated or partially saturated long after the smaller pores fill with water. Small gel and capillary pores in the cement matrix fill quickly on exposure to water, but larger pores (entrapped and entrained air voids) require longer times or other methods to achieve saturation. As such, it is important to quantitatively determine the water content and degree of saturation in air entrained cementitious materials. In order to further investigate properties of cement-based mortar, a model based on Beer's Law has been developed to interpret neutron radiographs. This model is a powerful tool for analyzing images acquired from neutron radiography. A mortar with a known volume of aggregate, water to cement ratio and degree of hydration can be imaged and the degree of saturation can be estimated. (C) 2015 The Authors. Published by Elsevier B.V.

AB Recent attention to K-12 education in science, technology, engineering, and mathematics (STEM) has revealed challenges in students' performance and persistence, particularly for groups that are underrepresented STEM fields. STEM shapes people's lives in fundamental ways. However, currently, the U.S. is faced with dual crises (1) a dearth of STEM learners and (2) a lack of learning environments and hands-on opportunities especially for underrepresented communities. Although these challenges are daunting, recent education policy developments are creating an unprecedented opportunity to address them. Individuals, educators, stakeholders and decision-makers across the nation are increasingly seeking methods and strategies to bolster scientific capabilities and the capacity of our teachers and students. This is vital to increase the national STEM talent pool and workforce necessary to sustain the economy and ensure that the U.S. remains a world leader in science and technology. CUNY Remote Sensing Earth System (CREST) Institute and its consortium at the City College of New York expanded the existing successful Summer High School Internship Program (SHIP) to create an exemplary science and engineering mentoring program for HS students from underrepresented communities within the five borough of NYC and make them "college ready" especially in fields of Remote Sensing of the Earth. The overarching goals of the project was to expand the number of HS students able to participate in summer research; to introduce pre-college credit bearing courses in MATLAB, GIS and Remote Sensing and introduce students to integrative research and learning modules through hands-on research projects. The objectives of this program was to motivate, inspire, engage and increase the underrepresented minority/underserved and STEM disadvantaged HS students in inter-disciplinary fields of Earth Systems, and Environmental Sciences and Engineering; to engage students in scientific research alongside faculty and graduate mentors; to bring excitement to students/interns through cutting-edge research and help set a STEM career pathways from high school to college. The authors look forward to sharing their summer 2014 High School experience through this presentation.

AB A novel method is proposed for the calibration of channel mismatch in a time-interleaved real-time digital oscilloscope (RTDO). A simple simultaneous equation is derived from the Fourier transform of the time-interleaved signals. Thus, it only requires a transfer function of time-interleaved ADCs (TIADCs), while most of previous works have employed additional filters. A measurement method for the transfer function of a commercial RTDO is also proposed. The accuracy of the calibration method is determined by the noise produced after the interleaving process. To validate the proposed method, we measure two-tone signals using a commercial RTDO. The calibrated results clearly show signals at spurious frequencies are substantially reduced.

The generator consists of a broadband comb generator followed by a filter and amplifier. As a demonstration, we constructed and calibrated a source suitable for calibrating vector signal analyzers operating between 43 GHz and 46.5 GHz. We then used the source to characterize the response of a commercially available vector signal analyzer. We compared the result with calibrations performed with a general-purpose source.

AB We developed physical models of commercially-available 2.4 mm and 3.5 mm coaxial calibration kits for vector network analyzers. These models support multiline thru-reflect-line (TRL) and open-short-load-thru (OSLT) calibrations, and include error mechanisms in each of the standards' constituent parameters that can be utilized in the NIST Microwave Uncertainty Framework to propagate uncertainties. For both connector sizes, we calibrated a network analyzer using the two calibration methods, and compared measurements and uncertainties made on a number of verification devices. In both cases, we showed that the two calibrations agree to within their respective uncertainties.

AB This paper presents an overview of the development of the Configurable Robotic Millimeter-Wave Antenna ( CROMMA) facility by the Antenna Metrology Lab at the National Institute of Standards and Technology ( NIST). NIST set out to develop an antenna measurement facility that would be reconfigurable to different near-field antenna measurement geometries and perform antenna measurements from 100 to 500 GHz. An industrial robotic arm, hexapod and precision rotator were integrated to make a unique antenna measurement facility. A laser tracker with the ability to monitor and record the six degrees of freedom of a target was employed to measure and provide feedback used to correct the actual path of the robotic arm and position of the hexapod and rotator.

AB It is extremely challenging to enable nanoscale patterning in three dimensional (3D) curved geometries using conventional nanolithographic approaches. In this paper, we describe a highly parallel approach that combines nanoimprint lithography (NIL) and thin film bilayer strain engineering to spontaneously roll-up nanopatterned membranes into curved geometries. Specifically, we first patterned a silicon nitride (Si3N4) / silicon (Si) bilayer using nanoimprint lithography followed by plasma etching to create well defined pores. The diameter of the pores was further reduced by physical vapor deposition of platinum to sizes as small as 50 nm. After patterning, the bilayers were released from the substrate by etching an underlying SiO2 sacrificial layer. Based on the high deposition stress values for low pressure chemical vapor deposition (LPCVD) deposited Si3N4 and Si, we varied the thickness of the bilayer to realize rolled-up tubes with different radii of curvature; these curvature values were in good agreement with a finite element analysis model (FEM). The assembled nanoporous tubes had well defined pores along their curved interface and can be applied for drug delivery, separations and ion-sensing devices. We highlight biocompatibility of the devices by encapsulating beta-TC-6 islet cells of relevance to cell encapsulation therapy for diabetes. More broadly, we believe that this approach of combining NIL with strain engineering processes could be utilized to create a range of precisely nanopatterned curved structures in a highly parallel manner.

AB Real-time electricity monitoring in residences is a growing market, with a number of systems being commercialized that provide feedback to occupants on electrical power and energy consumption. These systems are also useful for research purposes, by better quantifying occupant energy usage for input into whole building energy models. Different monitoring systems, however, may perform better in certain circumstances than in others, so this work discusses efforts to create residential electrical energy emulators that can be used to evaluate energy monitoring systems. Our research focuses on the efficacy of tools available to mimic individual electrical loads in residential buildings. In our study, appliances are simulated using typical load profiles, with programmable power and power factor. The advantage of the load simulator is that it provides a variety of fully controllable loads for experimentation. By applying this method, building energy analysis research will have more flexibility to mimic real household appliances and electrical loads than is currently available.

AB Software static analysis is one of many options for finding bugs in software. Like compilers, static analyzers take a program as input. This paper covers tools that examine source codewithout executing itand output bug reports. Static analysis is a complex and generally undecidable problem. Most tools resort to approximation to overcome these obstacles and it sometimes leads to incorrect results. Therefore, tool effectiveness needs to be evaluated. Several characteristics of the tools should be examined. First, what types of bugs can they find? Second, what proportion of bugs do they report? Third, what percentage of findings is correct? These questions can be answered by one or more metrics. But to calculate these, we need test cases having certain characteristics: statistical significance, ground truth, and relevance. Test cases with all three attributes are out of reach, but we can use combinations of only two to calculate the metrics.
The results in this paper were collected during Static Analysis Tool Exposition (SATE) V, where participants ran 14 static analyzers on the test sets we provided and submitted their reports to us for analysis. Tools had considerably different support for most bug classes. Some tools discovered significantly more bugs than others or generated mostly accurate warnings, while others reported wrong findings more frequently. Using the metrics, an evaluator can compare candidates and select the tool that aligns best with his or her objectives. In addition, our results confirm that the bugs most commonly found by tools are among the most common and important bugs in software. We also observed that code complexity is a major hindrance for static analyzers and detailed which code constructs tools handle well and which impede their analysis.

AB This paper presents an effective and simple image resizing method. Our method is an improved version of seam carving that changes the backtracking basis of seam carving. We use a Scale Invariant Feature Transform (SIFT) feature in our method. SIFT key points are mainly located on high -contrast regions of an image. By using saliency considering SIFT as our backtracking basis, a resized image can preserve the SIFT features of the original image. Therefore, the resized image can be more visually acceptable than the image resized by traditional seam carving.

AB A Body Area Network (BAN) is a radio interface standard for wireless connectivity of wearable and implantable sensors located inside or in close proximity to the human body. Medical applications requirements impose stringent constraints on the reliability, and quality of service performance in these networks. Interference from other co-located BANs or nearby devices that share the same spectrum could greatly impact the data link reliability in these networks. Specifically, the CSMA/CA MAC protocol as outlined in the IEEE802.15.6 BAN standard involves the use of an energy detection threshold to determine the status of the transmission channel i. e. idle versus busy. In this paper, we would like to show that the use of such static thresholds could negatively impact the performance of the system composed of multiple co-located BANs. It could also lead to starvation or unfair treatment of a node that is experiencing excessive interference due to its physical location relative to all other nodes in the system.

AB Infrared images are commonly afflicted by distortions such as non-uniformity. Non-uniformity is characterized by horizontal and vertical fixed pattern noise. Accurately estimating the amount of non-uniformity present in an image and removing that amount of non-uniformity noise are open problems. Several estimators of non-uniformity exist, but their ability to estimate degrades with the presence of other sources of noise. Specifically, most of these metrics lack the robustness demanded by a more complete non-uniformity model.
Previous non-uniformity correction algorithms are compared and found to underperform relative to a more complete model of non-uniformity that we have developed. Using this model, we have created a new denoising algorithm, which we call the Gaussian scale mixture perceptual pattern denoiser. The new model and algorithm can fully characterize non-uniformity using covariance matrices.

AB Designing applications for scalability is key to improving their performance in hybrid and cluster computing. Scheduling code to utilize parallelism is difficult, particularly when dealing with data dependencies, memory management, data motion, and processor occupancy. The Hybrid Task Graph Scheduler (HTGS) increases programmer productivity when implementing hybrid workflows that scale to multi-core and multi-GPU systems. HTGS manages dependencies between tasks, represents CPU and GPU memories independently, overlaps computations with disk I/O and memory transfers, keeps multiple GPUs occupied, and uses all available compute resources. We present an implementation of hybrid microscopy image stitching using HTGS that reduces code size by similar to 25% and shows favorable performance compared to a similar hybrid workflow implementation without HTGS. The HTGS-based implementation reuses the computational functions of the hybrid workflow implementation.

AB Tattoos have been used for many years to assist law enforcement in investigations leading to the identification of criminals and victims. A tattoo is an elective biometric trait that could contain more discriminative information to support person identification than traditional soft biometrics such as age, gender and race. While some research has been done in the area of image-based tattoo detection and retrieval, it is not a mature domain. There are no common datasets to evaluate and develop operationally-relevant tattoo recognition applications. To address this shortcoming, the NIST Tattoo Recognition Technology Challenge (Tatt-C) database was developed as an initial tattoo research corpus that addresses use cases representative of operational scenarios.
The Tatt-C database represents an initial attempt to provide a set of ground-truthed tattoo images focused on, but not limited to, five primary use cases. This paper describes the details of the database along with the experimental protocols and test cases that should be followed, which will enable consistent performance comparison of tattoo recognition methods.

AB Image retargeting attempts to adapt images to different devices while preserving the salient contents. Most existing methods address retargeting of a single image. In this paper, we propose a novel image retargeting method for resizing a pair of stereo images. Naively retargeting each image independently will distort the geometric structure and will impair the perception of the 3-D structure of the scene. We introduce an extension to the 2-D image retargeting method that works on a pair of stereo images. We demonstrate the performance of our method on a number of challenging indoor and outdoor stereo images. Experimental results show that our method is able to provide visually comfortable resized images when the resizing ratio is relatively high.

DE Renewable Energy based generation; optimization; game theory three
players; outsourced storage
AB Currently, the electricity demand is exponentially increasing due to the population growth. Therefore, the demand side management (DSM) is becoming unavoidable especially with the increasing use of renewable energy sources. One of the most known tactics of DSM is the use pricing strategies to threaten users to schedule their loads by controlling their own appliances. In this paper, a new model of electricity market operators is proposed based on three actors: the utility grid (G) with renewable energy (RE) generation, the electricity consumer (U) and a storage company (S). This approach aims to develop the adequate hourly prices which optimize the utility function of each operator. Then, in order to deal with this objective, two related games are defined. The first one is based on the satisfaction function of U and the G and aims to give the hourly prices of consumers' electricity bills. While the second one is based on the satisfaction function of G and S in order to optimize the hourly prices of G's electricity bills. Finally, a case study based on a given RE production and consumers load forecasts has been considered. Simulation results show that the obtained hourly prices allows the consumer load curve to follow the RE curve generation while achieving the main objective of the proposed approach.

First, we build a hierarchical topology through synchronously constructing and simplifying Contour Tree (CT) and Morse-Smale (MS) complex of scalar fields. We then introduce three algorithms based on the hierarchical topology: (1) topology-based multi-resolution contouring - an overview provided for a scalar field by extracting iso-values from the simplified CT and tracing approximate contours across the MS complex cells; (2) topology based spaghetti plots for uncertainty - a seeding scheme based on the hierarchical topology for visualizing uncertainty among ensemble scalar data; (3) virtual ribbons - a new scheme for visualizing multivariate data invented by overlapping visual ribbons which encode the scalar variation of a region covered by uniform contours. We compare the new approaches with current alternatives.

AB Numerical weather predictions have been widely used for weather forecasting. Many large meteorological centers are producing highly accurate ensemble forecasts routinely to provide effective weather forecast services. However, biases frequently exist in forecast products because of various reasons, such as the imperfection of the weather forecast models. Failure to identify and neutralize the biases would result in unreliable forecast products that might mislead analysts; consequently, unreliable weather predictions are produced. The analog method has been commonly used to overcome the biases. Nevertheless, this method has some serious limitations including the difficulties in finding effective similar past forecasts, the large search space for proper parameters and the lack of support for interactive, real-time analysis. In this study, we develop a visual analytics system based on a novel voting framework to circumvent the problems. The framework adopts the idea of majority voting to combine judiciously the different variants of analog methods towards effective retrieval of the proper analogs for calibration. The system seamlessly integrates the analog methods into an interactive visualization pipeline with a set of coordinated views that characterizes the different methods. Instant visual hints are provided in the views to guide users in finding and refining analogs. We have worked closely with the domain experts in the meteorological research to develop the system. The effectiveness of the system is demonstrated using two case studies. An informal evaluation with the experts proves the usability and usefulness of the system.

AB Smart manufacturing technologies require a cyber-physical infrastructure to collect and analyze data and information across the manufacturing enterprise. This paper describes a concept for a product lifecycle test bed built on a cyber-physical infrastructure that enables smart manufacturing research and development. The test bed consists of a Computer-Aided Technologies (CAx) Lab and a Manufacturing Lab that interface through the product model creating a "digital thread" of information across the product lifecycle. The proposed structure and architecture of the test bed is presented, which highlights the challenges and requirements of implementing a cyber-physical infrastructure for manufacturing. The novel integration of systems across the product lifecycle also helps identify the technologies and standards needed to enable interoperability between design, fabrication, and inspection. Potential research opportunities enabled by the test bed are also discussed, such as providing publicly accessible CAx and manufacturing reference data, virtual factory data, and a representative industrial environment for creating, prototyping, and validating smart manufacturing technologies.

DE Simulation; Manufacturing; Virtual Fusion
AB Simulation is an indispensable part of design and analysis in a near infinite space of applications. Every day, simulation is applied to new problems as well as giving further insight into existing ones. Additionally, advancements in computing have enabled simulation to continue contributing understanding in areas where it is already a ubiquitous tool. Manufacturing in particular has benefited a great deal from simulation techniques ranging from Finite Element Analysis (FEA) for product design, to Discrete Event Simulations (DES) for process planning. In recent times emulation has emerged as an effective means of process validation. Emulation typically refers to a testing process where the controllers or control code are in their final state, while the components they control are still virtual. Virtual Fusion takes this one step further in creating a Hybrid Process Simulation (HPS), where any component of the process may be physically present or completely simulated. This paper first defines and then discusses the characteristics necessary for the component simulations needed in an HPS. It then follows with a technological survey, a literature review of existing tools, and concludes with research challenges.

Plans
AB With the increasing attention directed to sustainable manufacturing, systematic methodologies are needed for not only incorporating the traditional performance indicators such as cost and quality, but also environmental impacts during the production stage. This requires the selection of processes and process settings for the production of the design features to be optimal (i.e., higher productivity and lower negative environmental impact). Oftentimes, during process planning the improvement of one performance indicator (e.g., energy consumption) is at the cost of other ones (e.g., tool usage). In this paper, we introduce a systematic methodology that enables the combined assessment of environmental sustainability and productivity for integrated process and production plans using multi-objective optimization techniques. A case study of machining processes in a machine shop has been performed to demonstrate the proposed methodology.

ID ATTACK GRAPHS
AB Securely configured Internet Protocol version 6 networks can be made resistant to network scanning, forcing attackers to propagate following existing benign communication paths. We exploit this attacker limitation in a defensive approach in which heightened security measures are deployed onto a select group of chokepoint hosts to enhance detection or deter penetration. Chokepoints are chosen such that, together, they connect small isolated clusters of the communication graph. Hence, attackers attempting to propagate are limited to a small set of targets or have to penetrate one or more chokepoints. Optimal placement of chokepoints requires solving an NP-hard problem and, hence, we approximate optimal solutions via a suite of heuristics. We test our algorithms on data from a large operational network and discover that heightened security measures are only needed on 0.65% of the nodes to restrict unimpeded attacker propagation to no more than 15% of the network.

AB Flooding caused serious losses in China in the past two decades; therefore, responding to and mitigating the impact of flooding is a task of critical importance. The traditional flood response process is usually very time-consuming and labor-intensive. The Service-Oriented Architecture (SOA)-based flood response is a method with low efficiency due to the large volume of geospatial data transfer, and this method cannot meet the real-time requirement of a rapid response to flooding. This paper presents an Agent-and Cloud-supported geospatial service aggregation to obtain a more efficient geospatial service system for the response to flooding. The architecture of this method is designed and deployed on the Cloud environment, and the flooding response prototype system is built on the Amazon AWS Cloud to demonstrate that the proposed method can avoid transferring large volumes of geospatial data or Big Spatial Data. Consequently, this method is able to achieve better performance than that of the SOA-based method.

AB Oceanic turbulence causes distortions of the bounded beam waves propagating underwater. The most obvious effects are the beam spread and beam wandering. Propagation theory identifies two distinct measures of the beam spread: Long-Term (LT) beam spread when the beam size is measured in the fixed coordinate system, and the Short-Term (ST) beam spread when the beam size is measured relative to the instantaneous position of the beam center. The LT beam size is not a very practicable measure of the beam spread because it requires a very stable setup both for the transmitter and receiver that cannot be provided on the mobile platforms. LT beam size is also sensitive to the pointing errors and large-scale gradients of the refractive index that are not associated with turbulence. The ST beam spread is free of these drawbacks, but have not been studied as thorough as the LT case. We present a theoretical model for the ST beam irradiance that is based on the parabolic equation for the beam wave propagation in random media, and Markov approximation for calculation of the statistics of the optical field. We propose approximation that allows introduction of the isoplanatic ST PSF, but retains the specifics of the beam wave. Unlike the LT PSF the ST PSF depends on the overall beam geometry. This offers an opportunity to optimize the beam geometry in terms of maximizing the axial ST irradiance. Calculations supporting this conjecture will be presented.

DE Asphalt; Rutting; Repeated Load Permanent Deformation; Minimum Strain
Rate
AB Currently, flow number (FN) is being used for measuring permanent deformation resistance of asphalt mixtures. The provisional AASHTO TP 79- 10 test method specifies the requirements of the FN test; however, there are undefined levels of test variables, such as temperature, axial stress, and confinement. Therefore, agreeable FN criteria that can reliably discriminate between various mixtures have not been established yet. As the asphalt industry continues to develop more sophisticated mixtures (Warm Mix, RAP and RAS), the FN value has failed to capture the true complexity of the asphalt mixtures. These shortcomings and the unpredictable testing time of the FN test have affected its usefulness for evaluating high temperature performance of asphalt mixtures. A new test procedure for evaluation of rutting susceptibility of asphalt mixtures is being proposed. The new procedure is conducted at one temperature and multiple stresses on the same replicate in three increments of 500 cycles, which only takes 33 minutes to complete. The property of the test is the permanent strain due to the last cycle of each test increment (Minimum Strain Rate, or MSR). A master curve is developed by plotting the MSR values versus parameter TP, which is a product of Temperature and Pressure. The MSR master curve represents the unit rutting damage (rut per axle) of asphalt mixtures at any stress and temperature and can be used in laboratory for material characterization, mix design verification, ranking of the mixtures, or for pavement design applications to predict rut depth for project climate and design traffic.

ID SCINTILLATION
AB The direct search for dark matter is entering a period of increased sensitivity to the hypothetical Weakly Interacting Massive Particle (WIMP). One such technology that is being examined is a scintillation only noble liquid experiment, MiniCLEAN. MiniCLEAN utilizes over 500 kg of liquid cryogen to detect nuclear recoils from WIMP dark matter and serves as a demonstration for a future detector of order 50 to 100 tonnes. The liquid cryogen is interchangeable between argon and neon to study the A(2) dependence of the potential signal and examine backgrounds. MiniCLEAN utilizes a unique modular design with spherical geometry to maximize the light yield using cold photomultiplier tubes in a single-phase detector. Pulse shape discrimination techniques are used to separate nuclear recoil signals from electron recoil backgrounds. MiniCLEAN will be spiked with additional Ar-39 to demonstrate the effective reach of the pulse shape discrimination capability. Assembly of the experiment is underway at SNOLAB and an update on the project is given. Published by Elsevier B.V.

ID FACE RECOGNITION; GRAND CHALLENGE
AB This report presents results from the Video Person Recognition Evaluation held in conjunction with the 11th IEEE International Conference on Automatic Face and Gesture Recognition. Two experiments required algorithms to recognize people in videos from the Point-and-Shoot Face Recognition Challenge Problem (PaSC). The first consisted of videos from a tripod mounted high quality video camera. The second contained videos acquired from 5 different handheld video cameras. There were 1401 videos in each experiment of 265 subjects. The subjects, the scenes, and the actions carried out by the people are the same in both experiments. Five groups from around the world participated in the evaluation. The video handheld experiment was included in the International Joint Conference on Biometrics (IJCB) 2014 Handheld Video Face and Person Recognition Competition. The top verification rate from this evaluation is double that of the top performer in the IJCB competition. Analysis shows that the factor most effecting algorithm performance is the combination of location and action: where the video was acquired and what the person was doing.

ID FACE-RECOGNITION ALGORITHMS; PERFORMANCE; DATABASE
AB Over the past decade, independent evaluations have become commonplace in many areas of experimental computer science, including face and gesture recognition. A key attribute of many successful independent evaluations is a curated data set. Desired things associated with these data sets include appropriateness to the experimental design, a corpus size large enough to allow statistically rigorous characterization of results, and the availability of comprehensive metadata that allow inferences to be made on various data set attributes. In this paper, we review a ten-year biometric sampling effort that enabled the creation of several key biometrics challenge problems. We summarize the design and execution of data collections, identify key challenges, and convey some lessons learned.

AB With the proliferation of biometric-based identity management solutions, biometric algorithms need to be tested now more than ever. Independent biometric technology evaluations are needed to perform this testing, but are not trivial to run, as demonstrated by only a handful of organizations attempting to perform such a feat. Worse, many software development packages designed for running biometric technology evaluations available today shy away from techniques that enable automation, a concept that supports reproducible research. The evaluation software used for testing biometric recognition algorithms needs to efficiently scale as the sample datasets employed by researchers grow increasingly large. With better software, additional entities with their own biometric data collection repositories could easily administer a reproducible biometric technology evaluation. Existing evaluation software is available, but these packages do not always follow best practices and they are lacking several important features. This paper identifies the necessary requirements and ideal characteristics of a robust biometric evaluation toolkit and introduces our implementation thereof, which has been used in several large-scale biometric technology evaluations by multiple organizations.

AB Face recognition by machines has improved substantially in the past decade and now is at a level that compares favorably with humans for frontal faces acquired by digital single lens reflex cameras. We expand the comparison between humans and algorithms to still images and videos taken with digital point and shoot cameras. The data used for this comparison are from the Point and Shoot Face Recognition Challenge (PaSC). For videos, human performance was compared with the four top performers in the Face and Gesture 2015 Person Recognition Evaluation. In the literature, there are two methods for computing human performance: aggregation and fusion. We show that the fusion method produces higher performance estimates. We report performance for two levels of difficulty: challenging and extremely-difficult. Our results provide additional evidence that human performance shines relative to algorithms on extremely-difficult comparisons. To improve the community's understanding of the state of human and algorithm performance, we update the cross-modal performance analysis in Phillips and O'Toole [22] with these new results.

AB Charge Pumping (CP) has historically been a widely utilized tool to study reliability-limiting interface and near interface trapping centers in Metal-Oxide-Semiconductor Field-Effect-Transistors (MOSFETs). However, conventional CP methods are not effective for modern highly scaled devices due to high gate leakage current to CP current ratios. Fortunately, a newly developed CP technique has been developed, called frequency modulated CP (FMCP), which overcomes the limitations of conventional measurements and permits full CP studies to be successfully applied to highly scaled devices. In this work, we evaluate the practicality and usefulness of implementing FMCP to characterize Intel's second generation 14nm tri-gate MOSFETs. This demonstration clearly highlights SMCP's power and ability to provide critical information in current and future highly scaled technology nodes.

DE Threat Modeling; Systematic Analysis; Cyber-Physical Systems; Case Study
AB Cyber-Physical Systems (CPS) are systems with seamless integration of physical, computational and networking components. These systems can potentially have an impact on the physical components, hence it is critical to safeguard them against a wide range of attacks. In this paper, it is argued that an effective approach to achieve this goal is to systematically identify the potential threats at the design phase of building such systems, commonly achieved via threat modeling. In this context, a tool to perform systematic analysis of threat modeling for CPS is proposed. A real-world wireless railway temperature monitoring system is used as a case study to validate the proposed approach. The threats identified in the system are subsequently mitigated using National Institute of Standards and Technology (NIST) standards.

Analysis showed that by decreasing all dimensions, a low loss, ultra-compact pi rad phase modulator is possible. Application of this type of nanomechanical modulator in a miniature 2 x 2 switch is suggested and an optical design numerically validated. The footprint of the switch is 0.5 mu m x 2.5 mu m.

AB The single motion cycles of an electrothermal actuator were measured with nanometer and microradian precision, using a recently introduced particle tracking method. The actuator linked two rigid bodies that translated and rotated. Stochastic input noise decoupled and coupled the two bodies within the play of the linkage, resulting in a nondeterministic output. The linkage was characterized using a simple model of the actuation mechanism, establishing a new approach to characterizing microelectromechanical systems (MEMS).

AB The smart grid is a complex system that comprises components from both the power grid and communication networks. To understand the behavior of such a complex system, co-simulation is a viable tool to capture the interaction and the reciprocal effects between a communication network and a physical power grid. In this paper, we systematically review the existing efforts of co-simulation and design a framework to explore co-simulation scenarios. Using the demand response and energy price as examples of smart grid applications and operating the communication network under various conditions (e.g., normal operation, performance degrade, and security threats), we implement these scenarios and conduct a performance evaluation of smart grid applications by leveraging a co-simulation platform.

ID NANOINDENTATION; RESISTANCE; BEHAVIOR
AB Polyethylene is an advantageous material for the construction of buried pipelines. It is corrosion resistant, seismic tolerant, and utilizes low cost installation methods. Pipe sections are often joined using thermal fusion processes. The strength of the joint is related to the ability of the polyethylene chains to inter-diffuse and form inter-crystalline tie-chains across the two polyethylene surfaces. Testing the strength of the fusion bond is difficult and a number of different destructive and non-destructive tests have been developed, but it is not possible to understand the impact of the fusion process on the local microstructure from these tests. In this work, instrumented indentation with a flat punch is used to measure the local viscoelastic behavior of five different polyethylene resins used for pipe manufacturing at short times. High strain behavior related to slow crack growth is measured using a strain hardening measurement under tension. The impact of thermal processing is investigated by imposing three different thermal cooling histories (0.4, 9, and 100 degrees C/min) on the polyethylenes. The goal is to determine if short-term creep under indentation is capable of accurately measuring; (a) bulk creep behavior, (b) impact of resin architecture, and (c) the impact of thermal processing. The results show that indentation using a flat punch is capable of measuring creep within the range of bulk creep behavior, but not sensitive to the slow crack growth resistance of the resin.

AB This report presents results from the Video Person Recognition Evaluation held in conjunction with the 11th IEEE International Conference on Automatic Face and Gesture Recognition. Two experiments required algorithms to recognize people in videos from the Point-and-Shoot Face Recognition Challenge Problem (PaSC). The first consisted of videos from a tripod mounted high quality video camera. The second contained videos acquired from 5 different handheld video cameras. There were 1401 videos in each experiment of 265 subjects. The subjects, the scenes, and the actions carried out by the people are the same in both experiments. Five groups from around the world participated in the evaluation. The video handheld experiment was included in the International Joint Conference on Biometrics (IJCB) 2014 Handheld Video Face and Person Recognition Competition. The top verification rate from this evaluation is double that of the top performer in the IJCB competition. Analysis shows that the factor most effecting algorithm performance is the combination of location and action: where the video was acquired and what the person was doing.

ID FACE-RECOGNITION ALGORITHMS; PERFORMANCE; DATABASE
AB Over the past decade, independent evaluations have become commonplace in many areas of experimental computer science, including face and gesture recognition. A key attribute of many successful independent evaluations is a curated data set. Desired things associated with these data sets include appropriateness to the experimental design, a corpus size large enough to allow statistically rigorous characterization of results, and the availability of comprehensive metadata that allow inferences to be made on various data set attributes. In this paper, we review a ten-year biometric sampling effort that enabled the creation of several key biometrics challenge problems. We summarize the design and execution of data collections, identify key challenges, and convey some lessons learned.

ID FACE RECOGNITION; GRAND CHALLENGE
AB This report presents results from the Video Person Recognition Evaluation held in conjunction with the 11th IEEE International Conference on Automatic Face and Gesture Recognition. Two experiments required algorithms to recognize people in videos from the Point-and-Shoot Face Recognition Challenge Problem (PaSC). The first consisted of videos from a tripod mounted high quality video camera. The second contained videos acquired from 5 different handheld video cameras. There were 1401 videos in each experiment of 265 subjects. The subjects, the scenes, and the actions carried out by the people are the same in both experiments. Five groups from around the world participated in the evaluation. The video handheld experiment was included in the International Joint Conference on Biometrics (IJCB) 2014 Handheld Video Face and Person Recognition Competition. The top verification rate from this evaluation is double that of the top performer in the IJCB competition. Analysis shows that the factor most effecting algorithm performance is the combination of location and action: where the video was acquired and what the person was doing.

AB Automobiles are incorporating more and more electronics from various industry sectors that have not been optimally designed for use inside the vehicle passenger compartment. Reliability and cost are two key considerations when incorporating traditional consumer electronics and military grade electronics for use in automotive applications. The drive for miniaturization coupled with automotive reliability expectations requires better understanding of material properties beyond standard bulk analysis. Long term reliability predictions require a basic understanding of how materials will fail under certain conditions. To date, the harsh automotive environmental conditions have not been translated to physical properties of material at the microscopic scale. Material failure physics is primarily only understood at the bulk level as opposed to performance at interfaces or other small geometrical structures used in automotive electronics. The opportunity in this project is to predict and understand functional performance of small geometries in harsh environments through measurement of material and interface properties. Conducting system level testing for every material and design can delay implementation and increase cost of new technologies, therefore a predictive methodology will be valuable to the industry. An iNEMI Automotive Materials project has been initiated to measure functional performance of small geometries through understanding a combination of material properties and interface properties. The end goal is to have the necessary information to predict reliability of technology to reduce design cycles. This would optimize reliability and reduce costs for the industry as a whole.
Project participants will lend expertise in identifying the dominant failure mechanisms of commonly used materials and components. Using this information, the team will prioritize key properties for predictive modeling of reliability and performance. The appropriate tests and test methodologies for small geometries and relevant interface properties will be identified. Recommendations for developing test methods may result in follow-on projects. This presentation will discuss the dominant failure mechanisms in automotive electronics for selected components and materials. The correlation of material properties to specific environmental conditions will be analyzed. Gaps between standard consumer electronic test methods and typical automotive test conditions will be identified. The team's methodology for analysis will be presented.

AB Wearable sensors are considered to be a key component of cognitive infocommunications systems. These sensors, which are basically enabler of inter-cognitive communication, will provide physical interfaces between humans and future information and communication technology (ICT) devices. Due to their small size, such sensors are often powered by small batteries which might necessitate frequent recharge or even sensor replacement. Energy harvesting can reduce the charging frequency of these sensors. Longer operational lifetime can simplify the everyday use of wearable sensors in many of their applications. In this paper, our objective is to estimate the average amount of kinetic energy that can be harvested to power a wearable device. To obtain this estimate, we have measured typical acceleration of the human body through the use of a triaxial accelerometer placed at various locations on the body surface. These locations are assumed to be associated with the typical placement of a wearable sensor. Using the mathematical model of a micro energy-harvester, instantaneous harvested power can be generated, and target statistics such as average power can be calculated. Our preliminary results show that kinetic-based micro harvesters could be a promising technology for prolonging the operational lifetime of wearable sensors.

AB This paper describes microwave characterization of coplanar waveguide (CPW) lines formed by ink-jet printed technology on flexible polyethylene terephthalate (PET) substrates. The reel-to-reel printing process uses inkjet printing as a precursor for 2 mu m copper plating, which allows significantly lowered resistances as compared to traditional inks. A multiline TRL calibration technique has been used to characterize the propagation constant and reflection coefficient of the CPW lines. With the aid of four sets of measurements at two identical labs, it is shown that the fabricated samples have contact repeatability, permitting redundant multiline calibrations

AB A Body Area Network (BAN) is a radio standard for wireless connectivity of wearable and implantable sensors located inside or in close proximity to the human body. Medical and some other applications impose stringent constraints on battery powered BAN reliability, quality of service, and power consumption. However, lack of coordination among multiple co-located BANs in the current BAN standard may cause unacceptable deterioration of BAN reliability and quality of service due to high levels of inter-BAN interference. Assuming Time Division Multiple Access (TDMA), this paper proposes inter-BAN interference mitigation with regret matching based transmission scheduling algorithm. This scheduling algorithm uses pattern of past interference for implicit coordination between different BAN transmissions. Simulation results demonstrate potential benefits of the proposed scheduling algorithm for inter-BAN interference mitigation.

AB Attribute Based Access Control (ABAC) is a popular approach to enterprise-wide access control that provides flexibility suitable for today's dynamic distributed systems. ABAC controls access to objects by evaluating policy rules against the attributes of entities (subject and object), operations, and the environment relevant to a request, but great care must be taken in setting up and maintaining the access control rules that allow such flexible operations. This article summarizes important considerations in ABAC deployment first introduced in the Guide to Attribute Based Access Control [1].

AB Automatic guided vehicles (AGVs), an industrial form of a mobile robot, typically navigate using a central computer commanding AGV movement on predefined paths. How well they follow these paths is not well-defined in research articles and their performance is reported in non-standard manufacturer specifications. Furthermore, AGV technology is advancing towards vision guidance to map and localize their position from onboard the vehicle, whereas performance evaluation of advanced navigation techniques is just beginning. This paper describes AGV experiments using ground truth measurement comparison for performance evaluation of AGV navigation. A generic test procedure and metrics, described herein, are to be recommended to ASTM F45, a recently formed committee on performance of AGVs, as a navigation test method for use by the AGV and mobile robot industries.

AB End-to-end latency is critical to many distributed applications and services that are based on computer networks. There has been a dramatic push to adopt wireless networking technologies and protocols (such as WiFi, ZigBee, WirelessHART, Bluetooth, ISA100.11a, etc.) into time-critical applications. Examples of such applications include industrial automation, telecommunications, power utility, and financial services. While performance measurement of wired networks has been extensively studied, measuring and quantifying the performance of wireless networks face new challenges and demand different approaches and techniques. In this paper, we describe our work in progress of designing a measurement platform based on the technologies of software-defined radio (SDR) and IEEE 1588 Precision Time Protocol (PTP) for evaluating the performance of wireless networks.

AB The National Oceanic and Atmospheric Administration's (NOAA) Center for Operational Oceanographic Products and Services (CO-OPS) currently maintains twenty-two operational Physical Oceanographic Real-Time System (PORTS (R)) observatories throughout the United States' coastal regions. Ocean current observations are among the multiple PORTS (R) data products that provide critical support for safe navigation and a variety of scientific and engineering applications. To ensure that its observing network provides the most accurate and up-to-date products available, CO-OPS routinely conducts test and evaluation of newly available oceanographic sensors and measurement systems. From October 10 - December 3, 2014, CO-OPS conducted a field test in the South Chesapeake Bay which included three acoustic current profiling and wave sensors deployed in bottom mounted, upward looking configuration 1) the TRDI 500 kHz Sentinel V, 2) the Nortek 600 kHz AWAC-AST, and 3) the Nortek 500 kHz Signature 500 AD2CP; and an AXYS Technologies TriAXYS (TM) directional wave buoy with current measurement capability provided by an integrated Nortek 600 kHz Aquadopp acoustic sensor. Also included in the deployment was a bottom mounted TRDI 600 kHz Workhorse Sentinel acoustic current profiling sensor. The test site was near the mouth of the bay where currents are predominantly tidal and the average water depth is approximately 15 meters (50 feet). During the test, currents at the site ranged in magnitude from approximately 0-0.75 m/s on a daily basis and reached as high as 1.2 m/s (2.3 knots) on one occasion. Also, three high wind storm events passed through the region and significant wave heights exceeded 2 m on multiple occasions.
Data results presented in this paper focus on comparison of currents measured by two of the bottom mounted sensors, the TRDI Workhorse and Nortek AWAC, and the TriAXYS (TM) wave buoy's Nortek Aquadopp sensor. Currents measured by the bottom mounted AWAC and Workhorse sensors showed excellent agreement throughout the entire test; differences in principle current axis headings remained less than 5 degrees and root mean squared deviations (RMSD) between the measured current magnitudes were within 4-5 cm/s over all profile depths. Comparisons of currents measured by these two bottom mounted sensors and the TriAXYS (TM) buoy's Aquadopp sensor showed good agreement in current direction but comparisons between current magnitudes varied throughout the test. During the first 20 days, currents measured by bottom mounted sensors did not exceed 1 m/s and comparison between bottom versus buoy mounted sensors' magnitudes were excellent; RMSDs remained within 5-6 cm/s. However, over the final 34 days of the test when currents measured by bottom mounted sensors often exceeded 1 m/s, the bottom versus buoy mounted sensors' current magnitude RMSDs were approximately twice as large, in the 11-14 cm/s range. Preliminary results provide no clear indication of significant effect of wave conditions on bottom versus buoy mounted ADCP comparisons. Rather there is a significant correlation between bottom versus buoy mounted sensors differences and the bottom mounted sensors' measured currents; the buoy mounted Aquadopp sensor appears to be biased toward higher values the majority of the times when bottom mounted sensors' measured currents exceeded 1 m/s. Several key features of current data collected during this test will be presented along with initial results from the investigation into differences between bottom versus buoy mounted ADCPs' measurements.

During the test, currents at the site ranged in magnitude from approximately 0-0.75 m/s on a daily basis and reached as high as 1.2 m/s (2.3 knots) on one occasion. Three high -wind storm events passed through the region and significant wave heights exceeded 2 m on multiple occasions.
Data results presented in this paper focus on comparison of wave measurements collected by the TriAXYSTm Next Wave II Directional Wave Buoy with Currents and the bottom -mounted TRDI 500 kHz Sentinel V. Currents measured by both devices are presented in [1]. Both instruments were deployed on 10 October, 2015; the Sentinel V operated until 2 November before ceasing data collection, possibly due to a faulty memory card. The TriAXYS buoy operated until recovery on 5 December 2015, transmitting wave data hourly and current data every 6 minutes via satellite in real time. Significant (Maximum) wave heights ranged from 0.15 (0.2) m to 2.5 (4.0) m and 5-7 second periods during the deployment, with the largest waves from the Northern quadrant, associated with strong northerly winds following cold front passages. In comparing bulk wave parameters, the two instruments agreed well on Maximum and Significant wave heigh and Peak period; in other measures of wave period (TMEAN and Tz), the Sentinel V showed a slight bias towards longer periods. Mean Wave Direction agreed well, to within 1 degree in the mean. Non -directional wave spectra were compared the Sentinel V estimated these using two methods, Sea Surface Height and Velocity. The two were highly consistent and agreed well with the TriAXYS spectra, in spite of differences in methodology and frequency resolution. A notable feature of the non -directional spectra was the appearance of relative maxima of lower frequency waves (around 10 seconds) regularly appearing in the records of both instruments. Directional spectra also agreed quite well, and showed that the low frequency waves were primarily from the south, even in the presence of northerly winds, and likely from the open ocean 20 miles south at the mouth of the Chesapeake Bay. Of 12 identified QARTOD tests, 6 were applied. In general very few data points failed any of those tests; they did prove instructive on monitoring real-time data quality. The limited amount of time between instrument recovery and publication submission, combined with the significant processing required in analysis of these data sets, has resulted in limited analysis to this point. There are further data, in particular from the 5-beam Sentinel V, that need to be evaluated; there are features and inconsistencies in the data that need to be explored; we expect these will support significant further analysis and reporting.

AB This article presents methods applied for automated detection of fish based on cascade classifiers of Haar-like features created using underwater images from a remotely operated vehicle under ocean survey conditions. The images are unconstrained, and the imaging environment is highly variable due to the moving imaging platform, a complex rocky seabed background, and still and moving cryptic fish targets. These images are released in a new image dataset, "labeled fishes in the wild," of in situ groundfishes, mainly rockfishes (Sebastes spp.) and other associated species. The dataset includes an annotated training and validation image set, as well as an independent test video image sequence. Several Haar cascades are developed from the training set and applied to the validation and test video images for evaluation. Based on performance evaluation using the validation set, true positive detection rates of 63 to 89% were achieved for seven classifiers. True positive detection rates for the test video were 66% to 81% for analyst-confirmed fish targets. Detector performance is dependent on training data, training and detection parameters, fish orientation, range to target, variable light intensity and attenuation.

AB The future of manufacturing lies in being able to optimize the use of resources to produce high quality product and adapt quickly to changing conditions. From smaller lot sizes, to more customization, to sudden changes in supply chain; the variability that manufacturers face is rapidly increasing. A key to enabling adaptive and smart manufacturing systems is the appropriate definition and use of information. Standards are fundamental 1) to facilitate the delivery of the right information at the right time, 2) to enable actions based on that information and 3) to reduce risk of technology adoption and development. This paper provides a review of the standards-a standards landscape-in which future smart manufacturing systems will operate. The landscape focuses on standards used to integrate within and across three manufacturing lifecycle dimensions: product, production system, and business. Opportunities and challenges for new standards are discussed. Emerging activities addressing these opportunities are presented. This paper will allow manufacturing practitioners to better understand the standards useful to integrate smart manufacturing technologies within their areas of expertise.

AB This paper discusses the potential advantages and pitfalls of using semantic web technologies in the process of preparing engineering analyses. Analytical tools are often not designed to be integrated with disparate information sources and general-purpose modeling tools and often do not support the detection of problems across domains. Conversely, modeling tools may not capture and represent explicitly the information needed to leverage the capabilities of analytical tools. The method described uses semantic web technology as the integrating mechanism between domain-specific models (DSM) and analytical tools. We describe a method and tools for representing analytical knowledge through semantic web ontologies that map between the metamodels of both the DSM and analytical tools. We compare an earlier tool chain prototype with a significantly revised prototype to reflect on the benefits of using semantic web technologies as an integrating mechanism. A potential advantage is the ability to explicitly and transparently represent the relationships between modeling and analytical tools.

AB Reducing cantilever sizes toward the nanoscale enables increased atomic force microscopy (AFM) speed while maintaining high image quality and avoiding sample damage. However downsizing below the optical diffraction limit strongly increases the readout noise to unacceptable levels for conventional far-field beam bouncing detection schemes. Here, we demonstrate fast-scanning AFM imaging with a cavity optomechanical transducer-based nano-cantilever with 2 MHz transduction bandwidth, 4 MHz resonance frequency, sub-picogram mass, 1 N/m stiffness, and 7 fm/Hz(1/2) displacement sensitivity.

AB NIST in Boulder Colorado investigated the correlations between impact test results obtained from standard, full-size Charpy specimens (CVN) and specimens with reduced thickness (sub-size Charpy specimens, SCVN) or reduced or scaled crosssection dimensions (miniaturized Charpy specimens, MCVN). A database of instrumented impact test results was generated from four line pipe steels, two quenched and tempered alloy steels, and an 18 Ni maraging steel. Correlations between specimen types were established and compared with previously published relationships, considering absorbed energy, ductile-to-brittle transition temperature, and upper shelf energy. Acceptable correlations were found for the different parameters, even though the uncertainty of predictions appears exacerbated by the expected significant experimental scatter.
Furthermore, we report on the development of MCVN specimens for the indirect verification of small-scale pendulum machines (with potential energies between 15 J and 50 J), which cannot be verified with full-size verification specimens. Smallscale pendulum machines can now be verified at room temperature with certified reference specimens of KLST type (3 mm x 4 mm x 27 mm), supplied by NIST at three certified absorbed energy levels (low energy, 1.59 J; high-energy, 5.64 J; super-high energy, 10.05 J). These specimens can also be used to verify the performance of instrumented Charpy strikers through certified maximum force values. Certified reference values for both absorbed energy and maximum force were established by means of an interlaboratory comparison (Round-Robin), which involved nine qualified and experienced international laboratories.

AB Pipelines are widely accepted to be the most economical method for transporting large volumes of hydrogen, needed to fuel hydrogen-powered vehicles. Some work has been previously conducted on the fatigue crack growth rates of base metals of pipeline materials currently in use for hydrogen transport and on pipeline materials that may be used in the future. However, welds and their heat-affected zones are oftentimes the source and pathway for crack initiation and growth. The heat affected zones of welds can exhibit low resistance to crack propagation relative to the base metal or the weld itself. Microstructural irregularities such as chemical segregation or grain-size coarsening can lead to this low resistance. Therefore, in order to have adequate information for pipeline design, the microstructures of the heat-affected zones must be characterized, and their mechanical properties must be measured in a hydrogen environment. With that in mind, data on the fatigue crack growth rate is a critical need. We present data on the fatigue crack growth rate of the heat-affected zones for two girth welds and one seam weld from two API 5L X52 pipes. The materials were tested in hydrogen gas pressurized to 5.5 MPa and 34 MPa at a cyclic loading rate of 1 Hz, and an R ratio of 0.5.

AB Data analytics is increasingly becoming recognized as a valuable set of tools and techniques for improving performance in the manufacturing enterprise. However, data analytics requires data and a lack of useful and usable data has become an impediment to research in data analytics. In this paper, we describe issues that would help aid data availability including data quality, reliability, efficiency, and formats specific to data analytics in manufacturing. To encourage data availability, we present recommendations and requirements to guide future data contributions. We also describe the need for data for challenge problems in data analytics. A better understanding of these needs, recommendations, and requirements may improve the ability of researchers and other practitioners to improve research and more rapidly deploy data analytics in manufacturing.

ID INTELLIGENT PRODUCTS
AB Physical products are becoming smarter because of their increased number of embedded sensors and their real-time information-processing capabilities. Data analytics, particularly predictive analytics, is one of the most important of these capabilities because it uses statistical or machine-learning techniques to determine causal relations between input and output parameters. Many researchers have addressed the challenges in creating and evaluating predictive models. Few, however, have discussed how to employ such models effectively throughout a product's life cycle.
In this paper, we address this issue by extending Product Lifecycle Management (PLM) systems to include "Smart Component" data models that incorporate predictive models as "parts" or "services" of products in their master records in PLM. These smart-component data models can be modularized, composed, reused, traced, maintained, and replaced on demand. We describe a prototype system to demonstrate the feasibility of the proposed data models using an open-source PLM platform.

ID BAYESIAN NETWORKS; INFORMATION
AB Understanding the sources of, and quantifying the magnitude of, uncertainty can improve decision-making and, thereby, make manufacturing systems more efficient. Achieving this goal requires knowledge in two separate domains: data science and manufacturing. In this paper, we focus on quantifying uncertainty, usually called uncertainty quantification (UQ). More specifically, we propose a methodology to perform UQ automatically using Bayesian networks (BN) constructed from three types of sources: a descriptive system model, physics-based mathematical models, and data. The system model is a high-level model describing the system and its parameters; we develop this model using the Generic Modeling Environment (GME) platform. Physicsbased models, which are usually in the form of equations, are assumed to be in a text format. The data is also assumed to be available in a text format.
The proposed methodology involves creating a meta-model for the Bayesian network using GME and a syntax representation for the conditional probability tables/distributions. The actual Bayesian network is an instance model of the Bayesian network meta-model. We describe algorithms for automated BN construction and UQ analysis, which are implemented programmatically using the GME platform. We finally demonstrate the proposed techniques for quantifying the uncertainty in two example systems.

AB In this paper, we propose an architectural design and software framework for fast development of descriptive, diagnostic, predictive, and prescriptive analytics solutions for dynamic production processes. The proposed architecture and framework will support the storage of modular, extensible, and reusable Knowledge Base (KB) of process performance models. The approach requires the development of automatic methods that can translate the high-level models in the reusable KB into low-level specialized models required by a variety of underlying analysis tools, including data manipulation, optimization, statistical learning, estimation, and simulation. We also propose an organization and key structure for the reusable KB, composed of atomic and composite process performance models and domain-specific dashboards. Furthermore, we illustrate the use of the proposed architecture and framework by performing diagnostic tasks on a composite performance model.

ID PREDICTION; DESIGN
AB Manufacturing generates a vast amount of data both from operations and simulation. Extracting appropriate information from this data can provide insights to increase a manufacturer's competitive advantage through improved sustainability, productivity, and flexibility of their operations. Manufacturers, as well as other industries, have successfully applied a promising statistical learning technique, called neural networks (NNs), to extract meaningful information from large data sets, so called big data. However, the application of NN to manufacturing problems remains limited because it involves the specialized skills of a data scientist.
This paper introduces an approach to automate the application of analytical models to manufacturing problems. We present an NN meta-model (MM), which defines a set of concepts, rules, and constraints to represent NNs. An NN model can be automatically generated and manipulated based on the specifications of the NN MM. In addition, we present an algorithm to generate a predictive model from an NN and available data. The predictive model is represented in either Predictive Model Markup Language (PMML) or Portable Format for Analytics (PFA). Then we illustrate the approach in the context of a specific manufacturing system. Finally, we identify future steps planned towards later implementation of the proposed approach.

AB This paper describes a real-time data collection framework and an adaptive machining learning method for constructing a real-time energy prediction model for a machine tool. To effectively establish the energy consumption pattern of a machine tool over time, the energy prediction model is continuously updated with new measurement data to account for time-varying effects of the machine tool, such as tool wear and machine tool deterioration. In this work, a real-time data collection and processing framework is developed to retrieve raw data from a milling machine tool and its sensors and convert them into relevant input features. The extracted input features are then used to construct the energy prediction model using Gaussian Process (GP) regression. To update the GP regression model with real-time streaming data, we investigate the use of sparse representation of the covariance matrix to reduce the computational and storage demands of the GP regression. We compare computational efficiency of sparse GP to that of full GP regression model and show the effectiveness of the sparse GP regression model for tracking the variation in the energy consumption pattern of the target machine.

These highlights are key developments needed over the next five to seven years in response to large-scale national and international climate community projects that depend on ESGF for success. Quality assurance and baseline performance from laptop to high performance computing characterizes available and potential data streams and strategies. These are required for interactive data collections to remedy gaps in handling enormous international federated climate data archives. Appropriate cyber security ensures protection of data according to projects but still allows access and portability to different ESGF and individual groups and users. A timeline and plan for forecasting interoperable tools takes ESGF from a federated database archive to a robust virtual laboratory and concludes the article.

DE data-driven manufacturing; energy prediction; neural networks;
prediction intervals
AB Many industries are applying various methods for optimizing energy use across the manufacturing life cycle. These methods are either physics-based or data-driven. Manufacturing systems generate a vast amount of data from operations and in simulations. Advances in data collection systems and data analytics (DA) tools have enabled the development of predictive analytics for energy prediction. Many of these prediction methods do not account for the uncertainty quantification-UQ (both in data and model). This work addresses the issue of uncertainty in predictive analytics.
This work focuses on metal cutting processes and presents a Neural Networks (NNs) model to predict the required energy consumption during the manufacturing of a part on a milling machine. The model accounts for the uncertainty associated with both the manufacturing processes parameters, and assumptions in building the prediction model. To achieve this, prediction intervals are estimated instead of point predictions. In order to increase the ability to generalize over new datasets, an ensemble model of neural networks (NNs) is used, and the k-nearest-neighbors (k-nn) approach is applied to identify similar patterns between training and test datasets to increase the accuracy of the results by using local information from the closest patterns of the training sets. Case study results demonstrate consistency and high prediction precision as compared to the individual NNs of the ensembles. Moreover, it is shown that with advanced data collection and processing techniques, one can construct a prediction model to predict the energy consumption of a machine tool for machining a part with multiple operations and process parameters.

AB The Information Access Division (IAD) of the National Institute of Standards and Technology (NIST) launched a new Data Science Initiative in the fall of 2015. This initiative focuses on evaluation-driven research and will establish a new Data Science Evaluation series to facilitate research collaboration, to leverage shared technology and infrastructure, and to further build and strengthen the data science community. The evaluation series will consist of a pre-pilot to be launched in the fall of 2015, a pilot evaluation to be launched in 2016, and a full-scale multiple-track evaluation in 2017. In addition to these evaluations, this new initiative aims to address several infrastructure challenges and to provide standards to encourage easier group collaboration.

AB An improved understanding of the spatial structure and movements of harvested populations can promote more efficient management of marine resources. Conventional tagging is a valuable approach to study the movements of marine fishes due to its relatively low expense and the typically broad spatial extent over which movements can be characterized. We present the findings of multiple tag return studies initiated in the estuaries of North Carolina during the past two decades to better understand habitat residency and migration patterns of Southern Flounder Paralichthys lethostigma, an economically important marine flatfish in the southeastern USA. Tag return data indicated large-scale (>50 km) movements of relatively large fish in the fall, which were presumably associated with offshore winter spawning migrations. Nearly all Southern Flounder that demonstrated large-scale movement were recovered to the south of the system in which they were tagged, suggesting that the spawning activity of fish using North Carolina estuaries may be concentrated mostly off the southeastern U.S. continental shelf. Tag returns from within multiple estuarine systems during the spring and summer were in close proximity to release sites (typically <1 km), suggesting limited movement during estuarine residency. Recaptures in the spring of fish tagged the previous summer or fall were also in close proximity to release sites, in some cases within the same estuarine creek, indicating limited movement of fish overwintering in the estuary as well. Our findings reveal saltatory movement dynamics of Southern Flounder characterized by limited movement during estuarine residency and large-scale movements in the fall associated with spawning migrations. Our synthesis of several tag return studies across multiple spatial scales should contribute to a better alignment of Southern Flounder management with their spatial dynamics.

AB Female Yellowfin Sole Limanda aspera, Alaska Plaice Pleuronectes quadrituberculatus, and Flathead Sole Hippoglossoides elassodon were collected from the eastern Bering Sea during known prespawning, spawning, and postspawning periods in 2012 and 2013, and their ovaries and otoliths were sampled for use in histological analysis to update historical maturity estimates. For fisheries management, new information on maturity at age can lead to possible changes in estimated reproduction potential (measured as female spawning stock biomass [SSB]) and values of fishing mortality reference points. Our analysis indicated that Yellowfin Sole currently mature at an age similar to that estimated in a study conducted 20 years ago. An evaluation of impacts on the stock assessment indicated that updated estimates of Yellowfin Sole SSB were over 7% higher, but the reference points only changed slightly. The first histologically derived maturity estimates for Alaska Plaice were close to the anatomically derived estimates (visual assessments from 1987), resulting in a marginal decrease (5%) in SSB, but changes in reference points were near 10%. Based on the new maturity estimates for Flathead Sole, SSB estimates increased by 7% compared with estimates currently used in the stock assessment, which relied on maturity data collected in 1999 and 2000. The change in Flathead Sole SSB was concomitant with changes of 16-18% in fishing mortality reference points. Our results indicated minimal differences from historical maturity estimates after re-examination, but in some cases those differences led to relatively large changes in the respective reference points, underscoring the reference points' sensitivity to changes in maturity. Incorporation of these new maturity estimates into the stock assessment process provides valuable updated information for fisheries managers. However, a more comprehensive sampling program is needed to investigate the spatial and temporal aspects of reproduction for each species.

AB Otolith chemical signatures of Red Snapper Lutjanus campechanus from six nursery regions were used to estimate the sources of recruits to four sampling regions in the western Gulf of Mexico (Gulf) and to estimate whether postsettlement mixing of Red Snapper occurs between the U.S. and Mexican portions of the western Gulf. In a previous study, region-specific otolith signatures (element : Ca ratios: Ba:Ca, Mg:Ca, Mn:Ca, Sr:Ca, and Li:Ca; stable isotope delta values: delta C-13 and delta O-18) were developed based on age-0 Red Snapper (2005-2007 year-classes) sampled from the six nursery areas. In the present study, subadult and adult Red Snapper (ages 1-3) belonging to those same year-classes were collected from four sampling regions within the western Gulf (two regions in U.S. waters; two regions along the Mexican continental shelf) during summer in 2006-2008. Left sagittal otoliths were used to age subadults and adults to the corresponding nursery year-classes, and right sagittal otoliths were cored for chemical analysis. Off the southwestern U.S. coast, the sampled age-1-3 Red Snapper included locally derived recruits as well as recruits from the northwestern Gulf nursery region. However, analytical results were inconclusive with respect to estimating the connectivity between Red Snapper populations in U.S. and Mexican waters of the western Gulf.

TI Calico Scallop Argopecten gibbus Abundance on the Cape Canaveral Bed and

AB Annual landings of the calico scallop Argopecten gibbus fishery in the southeastern United States increased from less than 3,000 kg in 1959 to 19.5 million kg of adductor muscle meat in 1984. The fishery began to collapse in early 1986 in Florida and fell below 1 million kg/year in the mid-1990s. From 2002 through 2011, the only reported landings were 550 kg in 2009, but annual landings of less than 200,000 kg beginning in 2012 indicate the resource rebounded enough in that year to create renewed interest in the fishery. When the fishery was developing, the National Marine Fisheries Service (NMFS) sponsored 59 cruises (1956 through the mid-1970s) to map the distribution of the stock and found the calico scallop stocks on Florida's east coast principally occurred around the 40-m depth contour near the shelf break. By the early 1980s, surveys were no longer routinely conducted. Two surveys in the mid-1990s were dedicated to investigating the collapse of the stock. The present study consisted of eight cruises from 2004 to 2006: four each to the beds off Cape Canaveral on the eastern coast and the poorly documented beds off southwestern Florida. Cruises studying baitfish and cruises in the Gulf of Mexico by the Southeast Area Monitoring and Assessment Program (SEAMAP) yielded data that provided additional calico scallop abundance estimates. Abundant, albeit small, scallops were found on both coasts during three of the four cruises to each coast though none were detected in fall 2004 on either coast. Our results concur with those historic NMFS surveys conducted prior to the period of heaviest exploitation of the resource (1974-1999); the center of distribution for calico scallops on the Cape Canaveral beds still occurs near the 40-m depth contour. The essential habitat for calico scallops, shell base, which was suspected to have declined during the most active fishery periods, was found to have persisted consistently at that depth. There were few scallops with a shell height greater than 40 mm, the minimal size considered acceptable for commercial exploitation.

AB Temporal and spatial variability in abundance often results from the effects of environmental and landscape variables interacting over multiple spatial scales, and understanding the complex interplay among these variables is key to elucidating the drivers of a species' population dynamics. We used a spatially explicit, variable-coefficient, generalized additive modeling approach with 24 years of fishery-independent trap data (N = 11,726 samples) to elucidate the spatiotemporal dynamics of size and size-specific CPUE of Black Sea Bass Centropristis striata along the southeastern Atlantic coast of the United States. Black Sea Bass catch exhibited complex spatial and temporal dynamics that were influenced by environmental, landscape, and sampling effects. Black Sea Bass were more commonly caught inshore than offshore, but were significantly smaller inshore and southward and larger offshore and northward in the study area. Moreover, the spatial distribution of Black Sea Bass changed as abundance varied within and among sampling seasons. Standardized mean length of Black Sea Bass also increased by more than 20% over the study period, from 230 mm TL in the early 1990s to 280 mm TL after 2010. These results elucidate the spatial and temporal dynamics of Black Sea Bass, inform population structure and indices of abundance, and provide an analytical framework that can be easily adapted to other species and systems.

ID SIMULATOR
AB In an effort to investigate scattering characteristics of debris particles in tornadoes, a numerical polarimetric radar emulator was developed. Regions of negative differential reflectivity have commonly been observed but are still yet to be explained physically. There are hypotheses that suggest common debris alignment and/or dominant scattering from objects with high radar-cross-section (RCS) values, but they are extremely challenging to verify due to the danger within tornadoes. It is, however, possible to numerically construct the scenes through representative simulation to verify the plausible causes. This serves as our primary motivation to develop the radar emulator. The novel aspects of this work are the realistic trajectory derivation, which is based on physical air-drag model, and the representative diversity of RCS contributions from each debris particle, developed through a realistic polarimetric RCS modeling and anechoic chamber measurements.

Biovolume per cell was calculated using the geometric shape of dinoflagellates at species level. Both thecate and athecate species were examined under light and scanning electron microscope. A total of 45 species were measured and their cell size was ranged between 20-450 mu m. Geometric forms of the species were seven classed into as ellipsoidal, spherical, double cone shape, prolate sphere, cone and half sphere, "cone+3 cylinder" shape, "ellipsoidal + 2 cone+ cylinder" shape, "cylinder+ cone" shaped. Total biovolume ranged from 3.743 x10(3) to 2.2 x10(5) mu m(3) cell(-1) and estimated cellular carbon content per cell ranged from 397 x 10(2) to 26.5 x 10(4) pg C cell(-1). Carbon and biovolume relationship was significant for thecate species which can thus be used for carbon flux studies.

AB Enterprise networks are migrating to the public cloud to acquire computing resources for promising benefits in terms of efficiency, expense, and flexibility. Except for some public services, the enterprise network islands in cloud are expected to be absolutely isolated from each other. However, some "stealthy bridges" may be created to break such isolation due to two features of the public cloud: virtual machine image sharing and virtual machine co-residency. This paper proposes to use cross-layer Bayesian networks to infer the stealthy bridges existing between enterprise network islands. Prior to constructing cross-layer Bayesian networks, cloud-level attack graphs are built to capture the potential attacks enabled by stealthy bridges and reveal hidden possible attack paths. The result of the experiment justifies the cross-layer Bayesian network's capability of inferring the existence of stealthy bridges given supporting evidence from other intrusion steps in a multi-step attack.

AB In this work, scanning near-field microwave imaging was implemented to test the feasibility of the approach for in-situ studies of nanoscale objects immersed in liquids under thin dielectric membranes. It was found that mechanical strength and stability of SiN membranes on Si frames are sufficient for contact mode imaging in a standard AFM setup. Model polystyrene particles immersed in glycerol in contact with the membrane from the cavity side could be reliably detected. The probing depth of this imaging mode can be estimated to be approximately 100 nm.

AB Document and physical standards play a vital role in security applications. Standards allow setting common measurement units, physical quantities and performance requirements for different types of radiation detection equipment and devices. Document standards provide a common ground for allowing consensus between user requirements, manufacturing process and testing capabilities. Physical standards address the reproducibility and traceability of measurements to national and/or international standards. Different standards have been developed for different types of instruments used in detection of illicit trafficking of radioactive materials and homeland security applications. These document standards are being used as part of a laboratory accreditation program that could be used for the development of an instrument certification program.

AB Troubleshooting systems is integral to experimental physics in both research and instructional laboratory settings. The recently adopted AAPT Lab Guidelines identify troubleshooting as an important learning outcome of the undergraduate laboratory curriculum. We investigate students' model-based reasoning on a troubleshooting task using data collected in think-aloud interviews during which pairs of students attempted to diagnose and repair a malfunctioning circuit. Our analysis scheme is informed by the Experimental Modeling Framework (EMF), which describes physicists' use of mathematical and conceptual models when reasoning about experimental systems. We show how students' work on a troubleshooting task can be mapped onto the EMF.

AB The American Physical Society recently released a statement calling on all university physics departments to provide or facilitate access to research experiences for all undergraduate students. In response, we investigated the current status of access to undergraduate research at University of Colorado Boulder (CU), a large research institution where the number of undergraduate physics majors outnumber faculty by roughly ten to one. We created and administered two surveys within CU's Physics Department: one probed undergraduate students' familiarity with, and participation in, research; the other probed faculty members' experiences as research mentors to undergraduates. We describe the development of these instruments, our results, and our corresponding evidence-based recommendations for improving local access to undergraduate research experiences. Reflecting on our work, we make several connections to an institutional change framework and note how other universities and colleges might adapt our process.

AB Building on successful work on studying and transforming our senior-level Advanced Lab course, we have transformed our junior-level Electronics course to engage students in a variety of authentic scientific practices, including constructing, testing, and refining models of canonical measurement tools and analog circuits. We describe our approach to the transformation, provide a framework for incorporating authentic scientific practices, and present initial outcomes from the project. As part of the broader assessment of these course transformations, we examine one course learning outcome: development of the ability to model measurement systems. We demonstrate that in the transformed course students demonstrate greater likelihood of identifying discrepancies between the measurement and the model and significantly greater tendencies to refine their models to reconcile with the measurement.

AB In situ temperature-resolved Near-edge X-ray Absorption Fine Structure (NEXAFS) measurements were performed on thereto-active ethylene-vinyl acetate (EVA) - multiwall carbon nanotube (MWCNT) composites 12 months following synthesis, and compared with spectra acquired shortly after synthesis to examine aging effects on non-covalent interactions. Room temperature spectra revealed no difference between unstrained and strained composites, suggesting relaxation. Further, energy shifts in pi* C=C resonances indicated a change in pi-pi interactions between MWCNT walls and chemical dispersant, supported also by AFM phase imaging. Temperature-resolved NEXAFS analysis showed a lack of interaction between nanotubes and polymeric chains, suggesting the chemical dispersant unlatched from MWCNT walls. The extent of this effect is finally quantified through a comparative study of spectral trends.

AB In this work, thermal properties especially phase change heat transfer properties of one new type of nanostructured heat transfer fluid: Water/Polyalphaolefin (PAO) nanoemulsion fluid are investigated. Water,is added into PAO fluid to form nanoemulsion fluids in which dispersed water nanodroplets are formed by self-assembly.
The liquid-to-vapor phase change results, expressed in terms of surface heat flux and heater temperature, have shown that the presence of water nanodroplets has a drastic impact on the liquid-to-vapor phase change behavior of the nanoemulsion fluid studied: the water nanodroplet formed inside can enhance its heat transfer coefficient by over 300% after the incipience of its phase change. In addition to that, the vaporization of the water nanodroplet inside is found to be different depending on the concentration of water inside, which happens to coincide with the structure change with different water concentrations as observed in SANS measurement. On the other hand, the effective specific heat is also found to increase with higher water concentration until reaching a maximum value which also happens to coincide with the structure transition from spherical to cylinder shape with the increasing of water concentrations as observed from SANS measurement. More study is still needed to understand the mechanism behind these phenomena.

AB We used broadband ferromagnetic resonance (FMR) spectroscopy to measure the second- and fourth-order perpendicular magnetic anisotropies in Ta/(t) Co60Fe20B20/MgO layers over a Co60Fe20B20 thickness range of 5.0 nm >= t >= 0.8 nm. For t > 1.0 nm, the easy axis is in the plane of the film, but when t < 1.0 nm, the easy axis is directed perpendicular to the surface. However, the presence of a substantial higher order perpendicular anisotropy results in an easy cone state when t = 1.0 nm. Angular-dependent FMR measurements verify the presence of the easy cone state. Measurement of the spectroscopic g-factor via FMR for both the in-plane and out-of-plane geometries suggests a significant change in electronic and/or physical structure at t approximate to 1.0 nm thickness.

AB A number of structural biology techniques such as nuclear magnetic resonance spectroscopy and small-angle neutron scattering can be performed with proteins with nuclei at natural isotope abundance. However, the use of proteins labeled with stable isotopes (H-2, C-13, and N-15) enables greater experimental flexibility. In this chapter, several methods for uniform and fractional protein labeling with stable isotopes using Escherichia coli in a defined media are described. The methods described can be used for labeling with single or multiple isotopes.

AB It is often necessary to obtain isotopically labeled proteins containing N-15, C-13, or H-2 for nuclear magnetic resonance; and H-2 for small-angle neutron scattering or neutron diffraction studies. To achieve uniform isotopic labeling, protein expression is most commonly performed in Escherichia coli or yeast using labeled media. However, proteins from extreme halophiles sometimes require a cellular environment with high ionic strength and cannot be heterologously expressed in E. coli or yeast in functional form. We present here methods for the cultivation of Halobacterium salinarum in isotopically labeled rich media, using commercially available isotopically labeled hydrolysates. The methods described here are both technically simple and relatively inexpensive.

AB We discuss the use of a metric based on the amplitude variation of a channel in the signal bandwidth to predict whether or not a digital wireless communication test system receiver will be able to demodulate a test signal. This metric is compared to another method consisting of the correlation calculated across the channel. A logistic regression analysis is used to provide a normalized assessment of the effectiveness of each metric as a predictive tool. We show that both metrics provide similar predictive capabilities, with the peak-to-minimum being significantly easier to calculate.

AB We discuss a new method for the measurement of electric (E) fields that will lead to a self-calibrating, direct SI-traceable E-field probe. The technique is based on radio frequency E-field interactions with alkali atoms placed in glass cells. After we present the concept of this approach and present some experimental data to show its validity, we give a discussion of the different types of uncertainties that are associated with this new approach. We discuss how the uncertainties of this approach compare to commonly used E-field measurement techniques.

ID DESIGN
AB This paper discusses the potential advantages and pitfalls of using semantic web technologies for representing and integrating modeling and analysis tools. Analytical tools are often not designed to be integrated with information sources and general-purpose modeling tools, and often do not support detection of problems across domains. Additionally, these modeling tools may not capture and represent explicitly the information needed to leverage the capabilities of analysis tools. The method described uses semantic web technology as the integrating mechanism between domain specific modeling (DSM) tools and analytical tools. We describe a method and tool set for representing the analytical knowledge through semantic web ontologies that map between the metamodels of both the DSM and analytical tools. We compare an earlier tool-chain prototype with a significantly revised prototype to reflect on the benefits from using semantic web technologies as an integrating mechanism. A potential advantage is the ability to represent the relationships between modeling and analytical tools explicitly and transparently. (C) 2015 The Authors. Published by Elsevier B.V.

AB Atmospheric aerosols and ozone (O-3) have lifetimes of days to weeks and continuously evolve chemically and physically. Frequent and globally spaced vertical profiles of O-3, aerosol optical density, particle size distribution, hygroscopic growth, and light absorption coefficients are highly desired in order to understand their controlling processes and subsequent effects on air quality and climate. High costs and logistical restrictions prohibit frequent profiling on a global scale using current technologies. We propose a new approach using state-of-the-art technologies including 3D printing and an unpowered small Unmanned Aircraft System to make the desired measurements at a fraction of the cost of current conventional methods.

AB High order finite element methods can solve partial differential equations more efficiently than low order methods. But how large of a polynomial degree is beneficial? This paper addresses that question through a case study of three problems representing problems with smooth solutions, problems with steep gradients, and problems with singularities. It also contrasts hadaptive, p-adaptive, and hp-adaptive refinement. The results indicate that for low accuracy requirements, like 1 % relative error, h-adaptive refinement with relatively low order elements is sufficient, and for high accuracy requirements, p-adaptive refinement is best for smooth problems and hp-adaptive refinement with elements up to about 10th degree is best for other problems.

AB We show that the vertical growth phase of IPOG is optimal for t-way test generation when t = 2, but it is no longer optimal when t is greater than 2. We present an improvement that reduces the number of tests generated during vertical growth. The vertical growth problem is modeled as a classical NP-hard problem called "Minimum Vertex Coloring". We adopted a greedy coloring algorithm to determine the order in which missing tuples are covered during vertical growth. We implemented a revised IPOG algorithm incorporating this improvement. The experimental results show that compared with the original IPOG algorithm, which uses an arbitrary order to cover missing tuples during vertical growth, the revised IPOG algorithm reduces the number of tests for many real-life systems.

DE BEN; Fault Localization; Combinatorial Testing
AB We present a combinatorial testing-based fault localization tool called BEN. BEN takes as input three types of information, including the subject program, the source code, an input parameter model, and a combinatorial test set created based on the input parameter model. It is assumed that the combinatorial test set has already been executed, and thus the execution status of each test is known. The output of BEN is a ranking of statements in terms of their likelihood to be faulty. In the fault localization process, a small number of additional tests are generated by BEN and need to be executed by the user. In this paper, we present the major user scenarios and the high-level design of BEN. BEN is implemented in Java and provides a graphical user interface that provides friendly access to the tool.

AB This short paper introduces a method for verifying equivalence classes for module/unit testing. This is achieved using a two-layer covering array, in which some or all values of a primary covering array represent equivalence classes. A second layer covering array of the equivalence class values is computed, and its values substituted for the equivalence class names in the primary array. It is shown that this method can detect certain classes of errors without a conventional test oracle, and an illustrative example is given.

DE Combinatorial Testing; Constraints; Forbidden Tuples
AB Constraint handling is a challenging problem in combinatorial test generation. In general, there are two ways to handle constraints, i.e., constraint solving and forbidden tuples. In our earlier work, we proposed a constraint handling approach based on forbidden tuples for software product line systems consisting of only Boolean parameters. In this paper, we generalize this approach for general software systems that may consist of other types of parameter. The key idea of our approach is using the notion of minimum forbidden tuples to perform validity checks on both complete and partial tests. Furthermore, we propose an on-demand strategy that only generates minimum forbidden tuples for validity checks as they are encountered, instead of generating all of them up front. We implemented our generalized approach with and without the on-demand strategy in our combinatorial testing tool called ACTS. We performed experiments on 35 systems using ACTS and PICT. The results show that for these 35 systems, our generalized approach performed faster than PICT and the constraint solving-based approach in ACTS. For some large systems, the improvement on test generation time is up to two orders of magnitude.

AB There has been a growing interest in the deployment of Phasor Measurement Units (PMUs) in a Distributed Generation (DG) grid system. A major obstacle is the lack of a communication network infrastructure that can support phasor measurements for distribution area monitoring as well as providing sensing capabilities for protection against undesirable grid dynamics. In the absence of such a network, the most cost-effective solution would be to consider a wireless network to support centralized control for situational awareness in a DG environment. Therefore, the main objective in this paper is to design and implement a synchrophasor network testbed using Wireless LAN (WLAN) technology. Based on a hierarchical network architecture, we propose an efficient method to reduce the synchrophasor data bandwidth, as well as provide capabilities for control and management at each hierarchical level. This testbed is then used to evaluate different network configurations under various test conditions.

AB Using measurements of the surface-ocean CO2 partial pressure (pCO(2)) and 14 different pcO(2) mapping methods recently collated by the Surface Ocean pcO(2) Mapping intercomparison (SOCOM) initiative, variations in regional and global sea-air CO2 fluxes are investigated. Though the available mapping methods use widely different approaches, we find relatively consistent estimates of regional pcO(2) seasonality, in line with previous estimates. In terms of interannual variability (IAV), all mapping methods estimate the largest variations to occur in the eastern equatorial Pacific. Despite considerable spread in the detailed variations, mapping methods that fit the data more closely also tend to agree more closely with each other in regional averages. Encouragingly, this includes mapping methods belonging to complementary types - taking variability either directly from the pcO(2) data or indirectly from driver data via regression. From a weighted ensemble average, we find an IAV amplitude of the global sea-air CO2 flux of 0.31 PgC yr(-1) (standard deviation over 1992-2009), which is larger than simulated by biogeochemical process models. From a decadal perspective, the global ocean CO2 uptake is estimated to have gradually increased since about 2000, with little decadal change prior to that. The weighted mean net global ocean CO2 sink estimated by the SOCOM ensemble is -1.75 PgC yr(-1) (1992-2009), consistent within uncertainties with estimates from ocean-interior carbon data or atmospheric oxygen trends.

We have developed a new consistent method for computing and employing T(tau) relations from these simulations, as surface boundary conditions for 1D stellar structure models. These 1D models have, in turn, had their mixing-length, alpha, calibrated against the averaged structure of each of the simulations. Both alpha and T(tau) vary significantly with T-eff and log g.

AB This paper presents a new approach to operational snow depth analysis. The analysis uses 2-dimensional optimal interpolation to blend various snow depth data weighted against their errors relative to a first guess and spatial correlations. The blended analysis is applied operationally within the National Oceanic and Atmospheric Administration (NOAA)'s Interactive Multi-Sensor Snow and Ice Mapping System (IMS) at its snow cover-classified grid points over the Northern Hemisphere. The 4-km snow depth estimates are blended from satellite-derived estimates of the Advanced Microwave Scanning Radiometer 2 (AMSR2) or the Advanced Technology Microwave Sounder (ATMS), in-situ surface reports and analyst estimates. Unique to the production is the application of snow depth estimates with the associated confidence values generated interactively from the analyst that are also ingested into the objective analysis and fully consistent with optimal interpolation method.

AB The proposed work aims to enhance the capabilities of the passive microwave measurements on board NOAA and MetOp satellites for snowfall identification. Two independent methods based on the same sensors (AMSU/MHS) were applied and qualitatively intercompared during snowstorms over Europe by using the NIMROD radar network as ground truth. The first method developed at NOAA is a statistical algorithm that computes the probability of snowfall using a logistic regression and the principal components of the high frequency brightness temperature measurements at MHS or ATMS channel frequencies 89 GHz and above. The second approach for snowfall detection (183-WSLSF) developed by CNR-ISAC is a prototype based on the preexistent 183-WSL retrieval method. By considering as limit of snowfall formation the rainy clouds located from a few hundred meters to 5-6 km, the 183-WSLSF combines channel sensitivities from 90 and 190 GHz to identify snowfall areas in the precipitating cores.

AB To understand the atmospheric phenomena such as rain rate, cloud liquid water, and total precipitable water from satellite microwave observations, the surface contribution should be accounted and be removed from the microwave signal. The objective of this proposed research is to develop a land surface emissivity that facilitates providing this information. The emissivity product will improve the Goddard PROFiling algorithm (GPROF) precipitation estimates. It makes use of microwave measurements from newly launched Global Precipitation Mission (GPM) Microwave Imager (GMI) sensor to produce an emissivity database for a range of frequencies from 6.9 GHz (C band) to high frequencies such as 183 GHz. The goal of this work is to inter-compare four global land surface emissivity products over various land-cover conditions to assess their consistency. The intercompared retrieved land emissivity products were generated over five-year period (2003-2007) using observations from the Advanced Microwave Scanning Radiometer - Earth Observing System (AMSR-E), Special Sensor Microwave Imager (SSM/ I), The Tropical Rainfall Measuring Mission (TRMM) Microwave Imager (TMI) and Windsat. First, all products were reprocessed in the same projection and spatial resolution as they were generated from sensors with various configurations. Then, the mean value and standard deviations of monthly emissivity values were calculated for each product to assess the spatial distribution of the consistencies/ inconsistencies among the products across the globe. The emissivity products were also compared to soil moisture estimates and satellite-based vegetation index to assess their sensitivities to the changes in land surface conditions.

AB We report on airborne measurements of the sea-surface normalized radar cross-section (NRCS) at incidence angles of approximately 22. obtained at both C-band and Ku-band in high-wind (>25m s(-1)) conditions. Measurements obtained over numerous research flights through tropical cyclones and high-latitude winter storms between 2011 and 2014 are composited to yield geophysical model functions in rain-free conditions. The present observations extend the results of [1], who reported high-wind NRCS for incidence angles from 30 degrees to 50 degrees, to a smaller incidence angle. Saturation of the mean NRCS is observed at both frequencies. In some cases the NRCS is observed to decrease with increasing wind speed beyond the saturation. The results have implications for planned and future scatterometers aiming to increase the observed swath width by extending the range of incidence angles.

AB The Cross-track Infrared Sounder (CrIS) on Suomi National Polar-orbiting Partnership Satellite (S-NPP) is a Fourier transform spectrometer and provides a total of 1305 and 2211 channels in normal spectral resolution (NSR) mode and full spectral resolution (FSR) mode, respectively, for sounding the atmosphere. NOAA operated CrIS in FSR mode on December 4, 2014 for S-NPP, and will operate CrIS in FSR mode for the Joint Polar Satellite System (JPSS). Based on CrIS Algorithm Development Library (ADL), CrIS full resolution processing system (CRPS) has been developed to generate the FSR Sensor Data Record (SDR). This code can also be run for normal mode and truncation mode SDRs. In order to select the best calibration algorithm for JPSS-1, four different calibration approaches are being implemented in the ADL full resolution code. In this study, evaluation results from different calibration approaches are presented and the ringing features observed in CrIS unapodized spectra are discussed.

AB The Visible Infrared Imager Radiometer Suite (VIIRS) has been on-orbit for more than three and half years. It has been scheduled to view the moon approximately monthly since its nadir door open on November 21, 2011. The scheduled lunar observations have been used to monitor the VIIRS reflective solar bands (RSB) on-orbit gain changes. The VIIRS RSB are primarily calibrated by an onboard Solar Diffuser (SD) panel and an accompanying Solar Diffuser Stability Monitor (SDSM). Due to non-uniformity of the SD degradation, the SD/SDSM calibration may have non-negligible errors, especially for the short wavelength bands. Since lunar surface is very stable, the Moon can be used to provide more reliable on-orbit long-term gain changes of the RSB. The RSB calibration coefficients derived from the lunar calibration are generally consistent with those derived from the SD/SDSM calibration, but clear differences in trend are seen, especially for the short wavelength bands.

AB The reflective solar bands (RSB) of the Visible Infrared Imaging Radiometer Suite (VIIRS) on board the Suomi National Polar-orbiting Partnership (SNPP) satellite are primarily calibrated on-orbit by a solar diffuser (SD) panel whose performance is monitored by an accompanying solar diffuser stability monitor (SDSM). In this paper, the SD and SDSM calibration methodology is reviewed and the results from the analysis of the up-to-date three and half years of mission data are presented. With the newly derived product of the SD bidirectional reflectance factors, the vignetting functions for the screens in the SD/SDSM system and the carefully selected "sweet spots", and the fully illumination region, the artificial seasonal patterns and noises in the derived SD degradation and the RSB calibration coefficients are removed or significantly reduced. The result shows that the SD degrades faster at short wavelengths while the RSB degrades in a much complex pattern.

AB A recurring challenge for microwave precipitation retrieval algorithms is the separation of precipitation from surface snow. Cold surfaces can have similar radiometric characteristics to suspended precipitation particles, such that surface snow reduces the detection accuracy of precipitation algorithms. Snow detection is typically performed using a collection of heritage algorithms, however surface snow can often go undetected and lead to erroneous precipitation retrievals. This study examines flagging procedures in the Goddard Profiling Algorithm 2010 V2 as it applies to the Advanced Scanning Microwave Radiometer 2 over the United States in the winter of 2014-2015. The legacy algorithms are often not reliable, such that a climatological screen is applied in known snowy regions. The diurnal cycle of brightness temperatures also complicates resolving rain when using the static legacy algorithms.

AB In this paper, we provide evaluations and assessments of the Visible Infrared Imaging Radiometer Suite (VIIRS) ocean color products, including normalized water-leaving radiance spectra nL(w)(lambda) at VIIRS five spectral bands, chlorophyll-a concentration (Chl-a), water diffuse attenuation coefficients at the wavelength of 490 nm, K-d(490), and at the domain of photosynthetically available radiation (PAR), K-d(PAR). Specifically, VIIRS ocean color products derived from the NOAA Multi-Sensor Level-1 to Level-2 (MSL12) ocean color data processing system are evaluated and compared with in situ data from the Marine Optical Buoy (MOBY) and measurements from the Moderate Resolution Imaging Spectroradiometer (MODIS). In general, VIIRS ocean color products are matched well with MOBY in situ measurements, and are also consistent with those from MODIS-Aqua. Ocean color products were found to be highly sensitive to some operational sensor calibration issues. We have improved sensor calibration by combining the lunar calibration into the current calibration method. Here, the ocean color products based on the new sensor calibration are evaluated. Our results show that VIIRS is capable of providing high-quality global ocean color products in support of the scientific research and operational applications.

AB This paper discusses the design of a microwave blackbody to be used as a primary laboratory standard for passive remote sensing applications. This temperature adjustable design is required to operate and be fully characterized from 10 to 220 GHz. We discuss the challenges involved in designing this type of calibration source and address how improvements can be made to increase performance over blackbodies typically flown on airborne and space-borne instruments. A simplified electromagnetic model for absorber layer optimization is introduced as the precursor to a finite-element, full-wave solution for the calculation of emissivity. A temperature simulation predicts the physical temperature of the blackbody and surrounding chamber. The simulated data are used as inputs to a rigorous calculation of the microwave brightness temperature radiated by the blackbody source. This calculation provides an estimate of the offset between measured physical temperature and radiometrically measured brightness temperature.

AB Radiometric calibration coefficients for the VIIRS reflective solar bands have been reprocessed from the beginning of the Suomi NPP mission until present. An automated calibration procedure, implemented in the JPSS operational data production system, was applied to reprocess onboard solar calibration data and solar diffuser degradation measurements. The latest processing parameters from the operational system were used to include corrected solar vectors, optimized directional dependence of attenuation screens transmittance and solar diffuser reflectance, updated pre-launch calibration coefficients without an offset term, and optimized Robust Holt-Winters filter parameters. The parameters were consistently used to generate a complete set of the radiometric calibration coefficients for the entire duration of the Suomi NPP mission. The reprocessing has also demonstrated that the automated calibration procedure can be successfully applied to all solar measurements acquired from the beginning of the mission until the full deployment of the automated procedure in the operational processing system.

ID RESOLUTION
AB Different aspects of the remote sensing inverse problem in operational environment are thoroughly discussed and various ambiguities in prevalent stochastic method namely optimal estimation method (OEM) are pointed out. To overcome these obscurities, a deterministic method namely regularized total least squares (RTLS) is proposed. For demonstration purposes, water vapor profiles retrievals from simulated Suomi-NPP CrIS hyperspectral measurements are considered. Synthetic CrIS radiances are generated using a line-by-line radiative transfer model (GENSPECT) with realistic radio-sonde profiles and US standard atmosphere as inputs. Our findings show that the current stochastic method, even with additional deterministic constraints (truncated singular value decomposition) applied on top of OEM, is unable to produce useful retrieval results, i.e., posterior error is more than the a priori error. In contrast, RTLS is able to produce deterministically unique results commensurate with the available information content in the measurements, which could result in a paradigm shift in operational satellite inversion.

AB This paper presents a comparison of methane (CH4), one important greenhouse gas in terrestrial atmosphere, observed from two hyperspectral infrared sensors on satellites, one is the Atmospheric Infrared Sounder (AIRS) onboard NASA/AQUA and the other is the Infrared Atmospheric Sounding Interferometer (IASI) onboard METEOP-A and -B. Comparison using about 500 cases shows the mean DOFs from AIRS is slightly smaller than IASI, with the difference of -0.049 +/- 0.152. Overall the retrieved CH4 from AIRS is larger than IASI, and their difference is 10.2 +/- 23.8 ppb below 650 hpa and 27.4 +/- 26.9 ppb above 350 hPa. In the most sensitive layer of infrared sounder between 350 and 650 hPa, their difference is as small as 2.8 +/- 17.2 ppb. Compared to aircraft measurements, AIRS retrievals tend to be overestimated while IASI retrievals tend to be underestimated in most cases, suggesting the necessarity to further improve the algorithms and call for more dedicated aircraft measurements for validation.

DE Suomi NPP; ATMS; Antenna Emissivity; Pitch-over Maneuver
AB The Advanced Technology Microwave Sounder (ATMS) onboard the Suomi National Polar-orbiting Partnership (NPP) satellite is a total power radiometer and scans across the track within a range of +/- 52.77 degrees from nadir. It has 22 channels and measures the microwave radiation at either quasi-vertical or quasi-horizontal polarization from the Earth's atmosphere. From the ATMS pitch-over deep space scan observations, it is found that the antenna reflector losses play an important role in calibration and dominates the scan angle dependent features in the ATMS antenna temperatures. Since the losses are small, they are difficult to measure by traditional means. However, they can be assessed directly from pitch over observations by using deep space radiation measured at different scan angle. This paper describes a physical model developed for the correction of reflector emissivity, which incorporates the angular dependent terms derived from the pitch-over maneuver data. Based on the pitch-maneuver data, the expected V/H polarization emissivity value is in the range of 0.002 to 0.0065. Considering the facts that ATMS is heritage of historical NOAA series microwave sounding instruments like MSU and AMSU, on which the reflector emissivity correction model can also be used to improve TDR/SDR data quality.

AB The Ozone Mapping and Profiler Suite (OMPS) consisting of three instruments, a Nadir Mapper (OMPS-NM), a Nadir Profiler (OMPS-NP) and a limb Profiler (OMPS-LP) was launched aboard Suomi NPP satellite in 2011. The instrument is also planned to be aboard JPSS satellite. The data from this instrument is processed at Interface Data Processing Segment (IDPS) built by Raytheon. The main products from OMPS include Total Column Ozone and Ozone Profile. Algorithm Development Library (ADL) framework mimics IDPS system and is used to test, troubleshoot and integrate algorithm updates. The algorithm integration team (AIT) at NOAA STAR is tasked to integrate the algorithm updates in ADL that could be simply plugged in the operational system. In this paper we will present the process in detail and will discuss the results of the latest update of V8 algorithm from V6 algorithm for OMPS Nadir Profile instrument.

AB After many years of development and experimental production, the United States National Oceanic and Atmospheric Administration (NOAA) transitioned the generation of winds derived from satellite synthetic aperture radar (SAR) data to operational status on May 1, 2013, employing SAR data from the Canadian RADARSAT-2 satellite. Winds of 500 m resolution are being produced from SAR data being purchased for the U.S. National Ice Center. Products are distributed internally within NOAA and via public websites. Currently the production of winds from Sentinel-1A data are being added to this system along with the ability to produce new product output formats (e.g., CoastWatch) and a wind archive is being developed by the NOAA National Centers for Environmental Information.

The tool is presently being used to test the capability to retrieve the main land parameters, namely soil moisture and vegetation biomass. An ongoing research is using the simulations to assess a multistatic concept which aims to take advantage of the combination of GNSS-R and radar backscattering data provided by a SAR or the GNSS receiver itself. Preliminary performance assessments are presented.

AB A hurricane maximum wind retrieval experiment is conducted using CYGNSS (Cyclone Global Navigation Satellite System) tracks simulated over a series of tropical cyclone scenes from the Hurricane Weather Research and Forecasting model (HWRF). This experiment makes use of a forward model relating simulated CYGNSS power-vs-delay waveforms to hurricane maximum winds. The forward model uses synthetic Willoughby modeled storms as 'truth' data. 1148 HWRF storm scenes from the 2010-11 hurricane seasons, from both the Atlantic and Eastern pacific basins, are used as input wind field to the forward model. Retrieved maximum winds are compared to both NHC best-track and HWRF. Results show a definite potential in using the CYGNSS data in retrieving hurricane maximum winds, although the current retrieval performance is hindered due to the symmetrical nature of the modeled Willoughby storms.

AB This paper proposes a position and stiffness bounding approach (PSBA) for improving "geometry transparency" in time-delayed teleoperations. The proposed method can rapidly update the local model location in master site to the contact location in the slave site. The proposed PSBA can therefore avoid instability problem due to both discrete force controller and sudden contact location changes (so called "model jump effect"). Effectiveness of the proposed approach is shown by 1-DOF simple contact experiment in 500ms round trip time delayed virtual environment.

AB The integral forms of the Kramers-Kronig (KK) relations that relate the real and imaginary parts, n' and n '', of a refractive index require the integral to be conducted over the full spectrum. In this paper, we derive a differential form of the KK relation that removes the need for knowing n '' at all frequencies (omega) in order to calculate n', which is more useful in measurements. Moreover, we show that, in a finite frequency range, our differential form of the KK relation can more accurately generate a resonant effective n' for an artificial medium composed of a periodic structure than do the integral forms of the KK relations, making use of n '' as obtained from a full-wave simulation.

AB We introduce a general criterion to predict conditions under which a flat planar medium is capable of imaging a point source. Such a planar medium, known as a flat lens, is attractive due to its potential for imaging over unbounded aperture dimensions. The criterion first assumes a point source on one side of the medium and then evaluates the position of the image based on the phase of the paraxial plane waves exiting the medium. The benefit of this criterion is that it makes no a priori assumption of the medium composition and is thus highly general. We apply this criterion to study a recent class of flat-lens structures made of nano-layers of metal and dielectric. The criterion is validated by comparison against past results. We use the criterion to design new flat lenses, such as a lens for transverse-electric polarization and a broad-band flat lens operating over the UV-visible spectral range.

DE Access control; policy; verification
AB Access control has been used in many systems such as military systems and business information systems. Access control protects sensitive information based on access control policies. Thus, assuring the correctness of policies is important. For this purpose, many access control policy verification (ACPV) tools have been proposed to check the correctness of policies. Since these tools have been designed by different mechanisms, they have different capabilities and performances. However, there lacks a set of standard approaches for evaluating them. Consequently, it is difficult for users to identify an appropriate tool for verifying their security policies. In this paper, we make an initial step towards building standard approaches for evaluating the capability and performance of ACPV tools. Specifically, we propose a set of reference metrics for analytically evaluating, as well as sets of oracles and test cases for empirically checking the run-time capability and performance of ACPV tools. To demonstrate, we apply these metrics, oracles and test cases on existing ACPV tools.

AB The Geostationary Operational Environmental Satellite (GOES-R) will have two magnetometers on a long boom to monitor the geomagnetic field and space weather. There are several sources of measurement error including spacecraft field, bias, misalignment, scale factor and sensor non-orthogonality. This paper is a first attempt at estimating overall system accuracy using simulation and covariance analyses. It also proposes calibration procedures for post-launch test and routine operations. The results suggest that small annual maneuvers would be highly advantageous for maintaining accuracy.

AB Time and its measurement belong to the most fundamental core of physics, and many scientific and technological advances are directly or indirectly related to time measurements. Timekeeping is essential to everyday life, and thus is the most measured physical quantity in modern societies. Time can also be measured with less uncertainty and more resolution than any other physical quantity. The measurement of time is of the utmost importance for many applications, including: global navigation satellite systems, communications networks, electric power generation, astronomy, electronic commerce, and national defense and security. This paper discusses how time is kept, coordinated, and disseminated in the Americas.

AB In 1997 the National Institute of Standards and Technology (NIST) embarked on a huge project to replace one of the most cited resources for mathematical, physical and engineering scientists, the Handbook of Mathematical Functions with Formulas, Graphs, and Mathematical Tables [Abramowitz and Stegun 1964], originally released by the National Bureau of Standards (NBS) in 1964. The 1997 project, designed to update and modernize the handbook, culminated in May 2010 with the launch of a freely available website, the NIST Digital Library of Mathematical Functions [DLMF] (http://dlmf.nist.gov/), and its print companion, the NIST Handbook of Mathematical Functions [Olver et al. 2010]. While the presence of graphics was sparse in the original handbook, the new resource contains more than 600 illustrations of high level mathematical functions, including close to 200 interactive 3D visualizations on the website. We provide the motivation for the visualization work through the context of the project and discuss our current implementation using X3DOM and WebGL.

ID WALKING
AB This research aims to develop a novel gait assistive device with enhanced gait stability and training efficiency for stroke patients. The proposed assistive device for mobility aid is composed of a motored wheel and a cane for providing only a light grip force, which prevent a patient using excessive support force of an upper limb like a conventional cane and motivate the patient to use more actively a paralyzed limb due to the reduced weight support. In addition, the proposed device can provide the user with intuitive and safe interaction during walking by integrating an F/T sensor and a tilt sensor at the cane, and a switch sensor at the hand grip. Also, admittance control has been implemented for a patient, it intuitively changes cane speed by measuring interaction forces at the hand grip. A hemi-paretic stroke patient participated in the walking experiments as a pilot study to verify effectiveness of the proposed system. The results showed that the patient could improve walking speed and muscle activation during experiments with a constant speed mode of the haptic cane. Moreover, in the admittance control mode of the haptic cane, the patient could keep higher preferred walking speed and higher gait stability regardless of magnitude of resistance forces. The proposed gait assistive device with cheap, compact and easy-to-use characteristics can provide efficient gait training modes to chronic stroke patients.

AB We designed and evaluated SplitVector, a new vector field display approach to help scientists perform new discrimination tasks on scientific data shown in virtual environments (VEs). Our empirical study compared the SplitVector approach with three other approaches of direct linear representation, log, and text display common in information-rich VEs or IRVEs. Our results suggest the following: (1) SplitVectors improve the accuracy by about 10 times compared to the linear mapping and by 4 times to log in discrimination tasks; (2) SplitVectors lead to no significant differences from the IRVE text display approach, yet reduce the clutter; and (3) SplitVector improved task performance in both mono and stereoscopy conditions.

AB Isolated qubits are a special class of quantum devices, which can be used to implement tamper-resistant cryptographic hardware such as one-time memories (OTM's). Unfortunately, these OTM constructions leak some information, and standard methods for privacy amplification cannot be applied here, because the adversary has advance knowledge of the hash function that the honest parties will use.
In this paper we show a stronger form of privacy amplification that solves this problem, using a fixed hash function that is secure against all possible adversaries in the isolated qubits model. This allows us to construct single-bit OTM's which only leak an exponentially small amount of information.
We then study a natural generalization of the isolated qubits model, where the adversary is allowed to perform a polynomially-bounded number of entangling gates, in addition to unbounded local operations and classical communication (LOCC). We show that our technique for privacy amplification is also secure in this setting.

AB The future of astronomy is inextricably entwined with the care and feeding of astronomical data products. Community standards such as FITS and NDF have been instrumental in the success of numerous astronomy projects. Their very success challenges us to entertain pragmatic strategies to adapt and evolve the standards to meet the aggressive data-handling requirements of facilities now being designed and built. We discuss characteristics that have made standards successful in the past, as well as desirable features for the future, and an open discussion follows.

AB To recognize people in unconstrained video, one has to explore the identity information in multiple frames and the accompanying dynamic signature. These identity cues include face, body, and motion. Our approach is based on video-dictionaries for face and body. Video-dictionaries are a generalization of sparse representation and dictionaries for still images. We design the video-dictionaries to implicitly encode temporal, pose, and illumination information. In addition, our video-dictionaries are learned for both face and body, which enables the algorithm to encode both identity cues. To increase the ability of our algorithm to learn nonlinearities, we further apply kernel methods for learning the dictionaries. We demonstrate our method on the Multiple Biometric Grand Challenge, Face and Ocular Challenge Series, Honda/UCSD, and UMD data sets that consist of unconstrained video sequences. Our experimental results on these four data sets compare favorably with those published in the literature. We show that fusing face and body identity cues can improve performance over face alone.

Wireless video capsule endoscope (VCE) is the first device taking 2-D pictures from the lesions and the abnormalities in the entire length of the small intestine. Since precise localization and mapping inside the small intestine is a very challenging problem, we cannot measure the distance traveled by the VCE to associate lesions and abnormalities to locations inside the small intestine, and we cannot use the 2-D pictures to reconstruct the 3-D image of interior of the entire small intestine in vivo. This paper presents the architectural concept of a novel cyber physical system (CPS), which can utilize the 2-D pictures of the small intestine taken by the VCE to reconstruct the 3-D image of the small intestine in vivo. Hybrid localization and mapping techniques with millimetric accuracy for inside the small intestine is presented as an enabling technology to facilitate the reconstruction of 3-D images from the 2-D pictures. The proposed CPS architecture provides for large-scale virtual experimentations inside the human body without intruding the body with a sizable equipment using reasonable clinical experiments for validation. The 3-D imaging of the small intestine in vivo allows a lesion to be pinpointed for follow-up diagnosis and/or treatment and the abnormalities may be observed from different angles in 3-D images for more thorough examination.

AB The freshwater trematode Nanophyetus salmincola has been demonstrated to impair salmonid immune function and resistance to the marine pathogen Vibrio anguillarum, potentially resulting in ocean mortality. We examined whether infection by the parasite N. salmincola similarly increases mortality of juvenile Chinook Salmon Oncorhynchus tshawytscha when they are exposed to the freshwater pathogens Flavobacterium columnare or Aeromonas salmonicida, two bacteria that juvenile salmonids might encounter during their migration to the marine environment. We used a two-part experimental design where juvenile Chinook Salmon were first infected with N. salmincola through cohabitation with infected freshwater snails, Juga spp., and then challenged with either F. columnare or A. salmonicida. Cumulative percent mortality from F. columnare infection was higher in N. salmincola-parasitized fish than in nonparasitized fish. In contrast, cumulative percent mortality from A. salmonicida infection did not differ between N. salmincola-parasitized and nonparasitized groups. No mortalities were observed in the N. salmincola-parasitized-only and control groups from either challenge. Our study demonstrates that a relatively high mean intensity (> 200 metacercariae per posterior kidney) of encysted N. salmincola metacercariae can alter the outcomes of bacterial infection in juvenile Chinook Salmon, which might have implications for disease in wild fish populations.

AB Fluid flow networks (FFNs) widely exist in water/ gas distribution, mine ventilation and other engineering systems. FFN control is crucial for the safe, stable and efficient operation of FFNs. In this paper, a simpler minimal representation of the nonlinear FFN model is given. Based on this simpler model, the strict dissipative feature of FNNs is revealed. Moreover, an adaptive decentralized FFN stabilizer that takes a proportional integral (PI) form is proposed. This stabilizer not only provides closed-loop stability but also does not need the values of network physical or hydraulic parameters. Due to its neat form, this new stabilizer can be easily implemented in the practical engineering. Finally, numerical simulation results show the feasibility of this newly-built FFN stabilizer.

AB The purpose of this paper is to introduce a dynamic electro-thermal simulation and analysis approach for device design and short-circuit safe-operating-area (SOA) characterization using a physics-based electro-thermal Saber (R)* model. Model parameter extraction, simulation, and validation results are given for several commercially available 4H-silicon carbide (SiC) power MOSFETs with a voltage rating of 1200 V and with current ratings of 31.6 A and 42 A. The electro-thermal model and simulations are used to analyze the short-circuit SOA including the measured failure time (t(failure)) and simulated device internal junction temperature (T-j) at failure for different gate voltages (V-GS) and drain voltages (V-DS).

AB In this work, an experimental study of the influence of Cu through-silicon via (TSV) diameter on stress build up was performed using synchrotron-based X-ray microdiffraction technique. Three Cu TSV diameters were studied; 3 mu m, 5 mu m and 8 mu m, all of which were fabricated in a single chip. Prior to the measurements, the die was annealed at 420 degrees C (30 min), yielding a fully grown and stable microstructure. The measured mean hydrostatic stresses in the Cu TSV were 185 +/- 14 MPa (3 mu m Cu TSV diameter), 147 +/- 10 MPa (5 mu m Cu TSV diameter) and 205 +/- 15 MPa (8 mu m Cu TSV diameter). As such, no conclusive stress dependence on Cu TSV diameter was determined. This is attributed to stress relaxation mechanisms including plastic deformation, grain boundary sliding, dislocation motion and the formation of cracks/voids which are otherwise neglected in many reported finite element modeling based studies. Additionally, this study underscores that the stress-strain behavior of Cu TSVs are significantly dependent on their thermal history and microstructural characteristics.

AB A polarimetric radar time-series emulator that produces both meteorological and non-meteorological radar echoes was developed. There are two main constituents in the radar emulator: a set of quasi-randomly populated tracers to emulate meteorological echoes and another set of point scatterers to emulate individual tornadic debris objects. Based on previous work to emulate meteorological radar echoes, the concept was expanded to the new framework. Two key innovations of the framework are the physically consistent trajectories of individual debris objects and realistic polarimetric radar cross section modeling of the debris targets.

AB Standard clutter filtering techniques in meteorological applications are limited to temporal filtering of radar data gathered by a single receiver. Using spatial data collected by the multi-channel receiver at the National Weather Radar Testbed phased array radar, novel clutter filtering techniques can be applied to meterological data. The spatial data collected by the sidelobe canceller channels is manipulated using linearly constrained minimum power (LCMP) beamforming with a quadratic constraint; constraints are selected to reject data from the sidelobes that is common to the sidelobe canceller channels and the sum channel, introducing nulls in the direction of ground clutter into the received beampattern and filtering out the clutter. This method of beamforming has proven effective in other fields, but has not yet been applied to meteorological surveillance radars. This paper explores the efficacy and efficiency of several methods of nullforming using data collected at the National Weather Radar Testbed.

AB The proposed Temporal Experiment for Storms and Tropical Systems (TEMPEST) satellite mission addresses key science needs related to cloud and precipitation processes using a constellation of five CubeSats with identical five-frequency millimeter-wave radiometers spaced 5-10 minutes apart in orbit. This CubeSat constellation will directly observe the time evolution of clouds to study the conditions that control the transition of clouds to precipitation. The TEMPEST millimeter-wave radiometers will penetrate into the cloud to directly observe changes as the cloud begins to precipitate or ice accumulates inside the storm. TEMPEST provides observations at five millimeter-wave frequencies from 90 to 183 GHz using a single compact instrument that is well suited for a 6U CubeSat architecture and fits well within the NASA CubeSat Launch Initiative capabilities.

AB A new time transfer modem for two-way satellite time and frequency transfer (TWSTFT) has been developed recently at Beijing Institute of Radio Metrology and Measurement (BIRMM). The DSSS and BPSK modulation techniques are used to generate a PRN signal. A FFT fast parallel algorithm is applied to achieve fast acquisition of the PRN modulated receiving signal. A 2nd order FLL assisted 3rd order PLL is designed to keep both of the performance of loop dynamic stress and carrier phase tracking accuracy, and a 2nd order DLL is used to track and measure the code phase. A short baseline TWSTFT experiment was done with two 1.2 m VSAT earth stations and a commercial geosynchronous orbit communication satellite to evaluate the modem's performance. The result shows very low noise with the standard deviation (1 sigma) equal to 0.13 ns at a 2.5 MChip/s code rate.

STATES
AB Atomic projection noise limits the ultimate precision of all atomic sensors, including clocks, inertial sensors, magnetometers, etc. The independent quantum collapse of N atoms into a definite state (for example spin up or down) leads to an uncertainty Delta theta(SQL) = 1/root N in the estimate of the quantum phase accumulated during a Ramsey sequence or its many generalizations. This phase uncertainty is referred to as the standard quantum limit. Creating quantum entanglement between the N atoms can allow the atoms to partially cancel each other's quantum noise, leading to reduced noise in the phase estimate below the standard quantum limit. Recent experiments have demonstrated up to 1 0 dB of phase noise reduction relative to the SQL by making collective spin measurements. This is achieved by trapping laser-cooled Rb atoms in an optical cavity and precisely measuring the shift of the cavity resonance frequency by an amount that depends on the number of atoms in spin up. Detecting the probe light with high total efficiency reduces excess classical and quantum back-action of the probe. Here we discuss recent progress and a technique for reducing the relative frequency noise between the probe light and the optical cavity, a key requirement for further advances.

AB The development of simple and reliable high stability clock lasers is of great importance for future state-of-the-art optical clocks [1]-[5] and for future transportable optical clocks [6], [7]. Further development of clock lasers with better stability has so far been hindered by thermal noise in the reference cavity used for laser stabilization and conventional approaches for improvements may be technically challenging. It has been proposed [8]-[11] to improve the stability and reduce the complexity of state-of-the-art laser frequency stabilization by exploiting cavity QED systems consisting of atoms with a narrow optical transition coupled to a single mode of an optical cavity.
The laser stabilization performance of a cavity QED system is affected by a number of system parameters such as the finite temperature of the atoms, the number of involved atoms and the laser power [12]-[14]. However, the dynamics of those elements have not yet been fully explored. Here we present a simple cavity QED system consisting of laser cooled strontium-88 atoms coupled to an optical cavity. We relate measurable quantities to the complex transmission coefficient which relates the input field to the output field. The optimal input power for stabilizing a laser to this system is experimentally determined and the optimal shot-noise-limited linewidth of the system is evaluated to 500 mHz. Furthermore, theoretical shot-noise-limited linewidths of similar cavity QED systems are evaluated for a number of different two electron systems.

AB In this work, amplification of surface acoustic waves (SAWs) by electron drift in a nanometer-scale two-dimensional electron gas (2DEG) is analyzed analytically. We compare the amount of acoustic power gain per SAW radian produced by electron drift in a bulk GaN thin film layer and in a GaN-based 2DEG layer. Calculations suggest that acoustic amplification in a 2DEG is independent on the SAW frequency while only a very narrow bandwidth of SAWs could be amplified in bulk. Furthermore, the peak power gain per SAW radian occurs at a more practical carrier density for a 2DEG than for a bulk material.

DE local area network; network time protocol (NTP); time transfer
AB The Network Time Protocol (NTP) is commonly utilized to synchronize computer clocks in packet-switched, wide area networks (WANs) such as the public Internet. The delay asymmetry in WANs, often due to inconsistent routing and/or bandwidth saturation, is usually the dominant source of error. It typically limits NTP time transfer uncertainty to about one millisecond. This paper discusses the uncertainty of NTP time transfer when network asymmetry is largely eliminated. We performed NTP measurements over a local area network (LAN) when both the server and client are referenced to a common clock. Three variations of a LAN are tested, including a direct connection between the server and client with an Ethernet crossover cable. The elimination of network asymmetry reveals other uncertainty sources that serve as practical limitations for NTP time transfer, including client instability, asymmetry in network interface cards, and server instability.

AB Global Positioning System (GPS) carrier-phase (CP) time transfer, as a widely accepted high-precision time transfer method, frequently shows a data-batch boundary discontinuity of up to 1 ns, because of the inconsistency of the phase ambiguities between two consecutive data batches. To eliminate the data-batch boundary discontinuity, several techniques have been proposed in recent years. The question is how large the solutions of these techniques differ from each other and how well the solutions are faithful to clocks. To answer these questions, this paper chooses two techniques to study: Revised RINEX-Shift (RRS) technique [1-2], and Phase Common-View (Phase-CV) technique [3-4]. This paper shows that the time deviation of the difference between the two techniques is below 100 ps, for an averaging time of less than 10 days. Especially, for an averaging time of less than 1 day, the time deviation is less than 30 ps. We also find that both RRS and Phase-CV match TWSTFT (two-way satellite time and frequency transfer) and TWOTFT (two-way optical-fiber time and frequency transfer) quite well. The difference is typically within +/-0.3 ns for more than 20 days. The above results are all based on a short-distance links (less than 2500 km). A long-distance comparison between these two techniques, such as a transatlantic link, has not yet been investigated.

AB Time is central to predicting, measuring and controlling properties of the physical world, and is one of the most important constraints distinguishing Cyber-Physical Systems (CPS) from distributed computing in general. However, mixing the cyber and the physical presents a fundamental challenge, since computers and communications systems have abstracted away the physical layer and timing is fundamentally a physical signal. While such abstractions have yielded significant benefits, time has been a casualty. CPS used in industry today achieve time-awareness by making use of time-aware fieldbuses and devices with specialized proprietary software. However, this approach has proved restrictive in both the topologies achievable and the scalability of networks beyond a certain size. The new era of the Internet-of-Things and the Industrial Internet is paving the way for convergence, where time needs to be an integral part of the cyber, making integration of cyber and physical seamless. However, this requires successful research in a number of different areas.
The National Institute of Standards and Technology (NIST) has formed a CPS Public Working Group (PWG), with members from global industry, academia and government. This CPS PWG is tasked with creating a set of frameworks and reference architectures for CPS, to promote proper function and interoperability. Public documents from this effort will soon be available. We discuss the timing section of the CPS PWG document and focus on the status of challenges and efforts to integrate time-sensitive with best-effort processes in CPS nodes and the networks that connect them.

AB The techniques of GPS time and frequency transfer (code based and carrier phase) and TWSTFT are widely used in remote clock comparison and in the computation of TAI and UTC. Many timing laboratories in the world utilize both techniques (GPS and TWSTFT transfer links) to compare each other's clocks. A time link must be calibrated to assure the time transfer accuracy. In many cases, calibration campaigns have been very infrequent due to the expense and lack of suitable equipment. In lieu of repeated calibrations, some information regarding the long-term stability of these links can be obtained through comparisons between the two links (a so called double difference). Without frequent calibrations it is impossible to tell where the instabilities originate, but information regarding the magnitude of the instabilities can be obtained from double difference data. We have been investigating the combined variations of GPS and TWSTFT links for a number of laboratory pairs, including both long and short baselines. Our results show that the relative change between GPS and TWSTFT transfer links can be as large as 6 to 7 ns over a few years and that all of the laboratory pairs that have been investigated show similar magnitudes in the double difference data. Currently the longest set of good double difference data is about 7 years. The study results point out the need for frequent calibration campaigns if accuracies at the nanosecond level are required.

The Working Group on Primary and Secondary Frequency Standards, WGPSFS, is an advisory body to the Time Department of the Bureau International des Poids et Mesures and to the Consultative Committee for Time and Frequency on matters related to primary and secondary frequency standards that are used to determine the rate of TAI. A current issue being considered by the WGPSFS is establishing guidelines for deciding when and how to make corrections for newly discovered frequency biases in primary frequency standards. This paper is intended to generate discussions on this topic in an audience wider than just the WGPSFS.

AB We describe the development and frequency instability measurements of a highly miniaturized, buffer gas cooled, trapped-ion atomic clock. The clock utilizes the 12.6 GHz hyperfine transition of the Yb-171(+) ion. A custom-built 3 cm(3) vacuum package containing the ion trap is integrated with other key elements of the atomic frequency standard, including a photo multiplier tube, miniaturized laser sources at 369 nm and 935 nm, a local oscillator, and control electronics. With the clock physics package assembled on a 10 cm x 15 cm breadboard, the long-term fractional frequency instability was measured to be 6 x 10(-14) at 25 days of integration. Later, the clock physics package was further miniaturized, and the frequency instability was measured to be 2 x 10(-11)/tau(1/2) at integration times up to 10,000 s.

We then discuss experimental and computational studies of the pyrolytic and oxidative pathways of model compounds of interest to the first-generation biofuels ethanol and biodiesel, along with an overview of current challenges in modeling these oxygenated compounds. We also describe experiments and calculations regarding reaction pathways of the small cyclic and bicyclic oxygenated systems used to model lignocellulosic (second-generation) biofuel chemistry, along with a summary of challenges in modeling these functionalized compounds. A general theme is the impact of the functional groups commonly found in first-generation and second-generation biofuels on thermochemistry and reaction pathways, compared with those of hydrocarbon fuels. We discuss recent progress with respect to third-and fourth-generation biofuels, as well as to biofuel combustion engineering challenges.

AB BACKGROUND: A 3.4kb deletion (3.4kb.) in mitochondrial DNA (mtDNA) found in histologically normal prostate biopsy specimens has been reported to be a biomarker for the increased probability of prostate cancer. Increased mtDNA copy number is also reported as associated with cancer.
OBJECTIVE: Independent evaluation of these two potential prostate cancer biomarkers using formalin-fixed paraffin-embedded (FFPE) prostate tissue and matched urine and serum from a high risk cohort of men with and without prostate cancer.
METHODS: Biomarker levels were detected via qPCR.
RESULTS: Both 3.4kb. and mtDNA levels were significantly higher in cancer patient FFPE cores (p = 0.045 and p = 0.070 respectively at >90% confidence). Urine from cancer patients contained significantly higher levels of mtDNA (p = 0.006, 64.3% sensitivity, 86.7% specificity). Combining the 3.4kb Delta and mtDNA gave better performance of detecting prostate cancer than either biomarker alone (FFPE 73.7% sensitivity, 65% specificity; urine 64.3% sensitivity, 100% specificity). In serum, there was no difference for any of the biomarkers.
CONCLUSIONS: This is the first report on detecting the 3.4kb. in urine and evaluating mtDNA levels as a prostate cancer biomarker. A confirmation study with increased sample size and possibly with additional biomarkers would need to be conducted to corroborate and extend these observations.

AB Sea surface temperature (SST) retrieved from Advanced Very High Resolution Radiometer (AVHRR) onboard National Oceanic and Atmospheric Administration (NOAA) polar orbiting environmental satellites were validated in the East/Japan Sea (EJS) using surface drifter measurements as ground truths from 2005 to 2010. Overall, the root-mean-square (rms) errors of multichannel SSTs (MCSSTs) and non-linear SSTs (NLSSTs) using global SST coefficients were approximately 0.85 degrees C and 0.80 degrees C, respectively. An analysis of the SST errors (satellite - drifter) revealed a dependence on the amount of atmospheric moisture. In addition, satellite-derived SSTs tended to be related to wind speeds, particularly during the night. The SST errors also demonstrated diurnal variations with relatively higher rms from 0.80 degrees C to 1.00 degrees C during the night than the day, with a small rms of about 0.50 degrees C. Bias also exhibited reasonable diurnal differences, showing small biases during the daytime. Although a satellite zenith angle has been considered in the global SST coefficients, its effect on the SST errors still remained in case of the EJS. Given the diverse use of SST data, the continuous validation and understanding of the characteristic errors of satellite SSTs should be conducted based on extensive in-situ temperature measurements in the global ocean as well as local seas.

AB In a 3-part series of papers, of which this paper is Part II, we investigate the applicability of the fully quadratic hexa-27 element (see Part I) to four problems of interest to the pressure vessels and piping community: (1) The solid-element-based analysis of a welded pipe elbow with a longitudinal surface crack in one of its weldments. (2) The solid-element-based analysis of the elastic bending of a simple cantilever beam, of which the exact solution is known. (3) The tetra-04 element-based analysis of the deformation of a wrench. (4) The shell-element-based analysis of a barrel vault. In this paper, we develop a two-step method first to estimate the uncertainty of a converging series of finite-element-mesh-density-parametric solutions using a 4-parameter logistic function, and then to extrapolate the results of a specific quantity (e.g., a stress component) to an extremely fine mesh density approaching the infinite degrees of freedom. The estimated parameter of the upper bound of the logistic function serves as the "best" estimate of the chosen quantity such as a specific stress component. Using a super-parametric approach, as described in Part III of this series, we show that the hexa-27 element is superior to tetra-04, hexa-08, and hexa-20. Published by Elsevier Ltd.

AB In most finite-element-analysis codes, accuracy is achieved through the use of the hexahedron hexa-20 elements (a node at each of the 8 corners and 12 edges of a brick element). Unfortunately, without an additional node in the center of each of the element's 6 faces, nor in the center of the hexa, the hexa-20 elements are not fully quadratic such that its truncation error remains at h(0)boolean AND 2, the same as the error of a hexa-8 element formulation. The symbol (boolean AND) denotes raising the preceding quantity to a power of the subsequent quantity. To achieve an accuracy with a truncation error of h(0)boolean AND(3), we need the fully-quadratic hexa-27 formulation. A competitor of the hexa-27 element in the early days was the so-called serendipity cubic hexa-32 solid elements (see Ahmad, Irons, and Zienkiewicz, Int. J. Numer. Methods in Eng., 2:419-451 (1970)). The hexa-32 elements, unfortunately, also suffer from the same lack of accuracy syndrome as the hexa20's. In this paper, we investigate the applicability of the fully quadratic hexa-27 elements to three problems of interest to the pressure vessels and piping community: (1) The shell-element based analysis of a barrel vault. (2) The solid-element-based analysis of a welded pipe elbow with a longitudinal surface crack in one of its weldments. (3) The solid-element-based analysis of the elastic bending of a simple cantilever beam. Significance of the highly accurate hexa-27 formulation and a comparison of its results with similar solutions using ABAQUS hexa-8, and hexa-20 elements, are presented and discussed.

AB Future policy decisions related to the control of engineered nanomaterials during consumer use and disposal will be predicated in part on their toxicities to natural environmental systems. Using titanium dioxide nanoparticles (nTiO(2)) as a model nanomaterial, this chapter critically evaluates the capacity of existing ecotoxicology literature to communicate the potential for harm to environmental systems by searching for confluence between the following: (a) nTiO(2) concentrations expected in surface waters; (b) nTiO(2) concentrations that result in specific toxicological responses to aquatic organisms; and (c) the availability of reliable methods or instrumentation that can quantitatively measure nTiO(2) concentrations in real aqueous solutions. This examination shows that direct measurements of nTiO(2) loading in aquatic ecosystems are limited by a dearth of analytical techniques that can simultaneously measure nTiO(2) size and concentration. Model predictions suggest that nTiO(2) concentrations concentrations in surface waters are likely to be significantly less than 100 mu g L-1, yet relatively few ecotoxicology studies use similarly low exposure doses. In fact, a survey of 30 well -cited nTiO(2) ecotoxicology papers found that only 22% of the associated experimental treatments used an environmentally relevant concentration of 100 mu g L-1 or lower, despite reliable indications that these doses often result in toxic responses. The analysis presented in this chapter suggests that significant questions remain regarding the concentrations and toxicities of engineered nanomaterials in real aquatic systems, which will need to be addressed before the development of scientifically sound policies and regulations.

AB We describe the design and operation of a spectrally programmable solar simulator capable of being concentrated to very high irradiance for the testing of multi-junction concentrator solar cells. The simulator utilizes a spatially coherent, super-continuum laser as the light source and a hybrid pair of prism-based spectrometers with spatial light modulators to precisely control the spectrum. Spectra are presented which simulate scaled versions of the AM 1.5 solar reference spectrum, correct for spectral mismatch, and model attenuation from increasing air-mass. The simulation of attenuated spectra may be used to study conditions representative of changes in location, weather, time of day, and time of year. We used the programmable simulator to test a multi-junction solar cell at up to 138 suns. We used a static, non-programmable version of the simulator to test the same cell at well over 500 suns. Technical improvements which would achieve substantial increases in irradiance and/or cell illumination area are described.

DE thin film photovoltaics; electron beam induced current; surface
recombination
AB Electron beam induced current (EBIC) is a powerful technique which measures the charge collection efficiency of electron-hole pairs generated by an electron beam. EBIC offers sub-micron spatial resolution and is naturally suited to study polycrystalline materials. Ideally, an EBIC measurement reflects the spatially resolved quantum efficiency of the solar cell. However, critical analysis of low energy EBIC data obtained on CdTe-CdS solar cells indicates that the EBIC signal is not simply proportional to the collection probability of a working device. As a step towards more quantitative analysis of EBIC measurements of these materials, we develop models of the collection efficiency which account for surface recombination in depletion regions and screening of built-in fields from carrier accumulation. We discuss how these models can be applied to obtain quantitative data on grain boundaries in polycrystalline materials.

ID SOLAR-CELLS; LENGTHS
AB Organometal halide perovskite CH3NH3PbI3 solar cells have witnessed unprecedented progress in power conversion efficiency, reaching more than 20 % within 5 years. Despite this rapid progress, there remain open questions about the basic properties of these materials, such as the role of the polar molecule CH3NH3 (methylammonium), and the possible existence of ferroelectric ordering, and its role in device operation. Using first-principles density-functional theory, we investigated the effect of molecular alignment on the electronic structure. We find that the molecular alignment significantly modifies the near-gap states indirectly through the induced structural distortion of the (PbI6)(4-) octahedron. The reduction in symmetry due to this distortion, combined with strong spin-orbit coupling of Pb, leads to a Rashba-like splitting of valence and conduction bands. This in turn leads to reduction of the degeneracy of the valence and conduction bands. These results imply that the electrical and optical properties are highly sensitive to ordering of the CH3NH3 dipole orientation.

DE reliability; durability; thermal activation
AB Reduced optical transmittance of encapsulants resulting from ultraviolet (UV) degradation has frequently been identified as a cause of decreased PV module performance through the life of service in the field. The present module safety and qualification standards, however, apply short UV doses only capable of examining design robustness or "infant mortality" failures. Essential information that might be used to screen encapsulation through product lifetime remains unknown. For example, the relative efficacy of xenon-arc and UVA-340 fluorescent sources or the typical range of activation energy for degradation is not quantified. We have conducted an interlaboratory experiment to provide the understanding that will be used towards developing a climate-and configuration-specific (UV) weathering test. Five representative, known formulations of EVA were studied in addition to one TPU material. Replicate laminated silica/polymer/silica specimens are being examined at 14 institutions using a variety of indoor chambers (including Xenon, UVA-340, and metal-halide light sources) or field aging. The solar-weighted transmittance, yellowness index, and the UV cut-off wavelength, determined from the measured hemispherical transmittance, are examined to provide understanding and guidance for the UV light source (lamp type) and temperature used in accelerated UV aging tests.

AB We compare local carrier dynamics in n-CdS/p-CdTe solar cells, where the electron-hole pairs are generated by either near-field optical illumination or highly focused electron beam excitation. An ion beam milling process was used to prepare a smooth surface of cross-sectional devices. T he spatially resolved photocurrent images confirm high carrier collection efficiency at grain boundaries. An analytical model was used to extract material parameters at the level of single grains. We find that the minority carrier diffusion lengths extracted from both local measurements are in excellent agreement, but are smaller than the values determined from macro-scale measurements.

AB Extremely scaled high-k gate dielectrics with high quality electrical interfaces with arsenide (As) and antimonide (Sb) channels are used to demonstrate complimentary 'all III-V' Heterojunction Vertical Tunnel FET (HVTFET) with record performance at vertical bar V-DS vertical bar=0.5V. The p-type TFET (PTFET) has I-ON=30 mu A/mu m and I-ON/I-OFF=10(5), whereas the n-type TFET (NTFET) has I-ON=275 mu A/mu m and I-ON/I-OFF=3x10(5), respectively. NTFET shows 55mV/decade switching slope (SS) while PTFET shows 115mV/decade SS in pulsed mode measurement. Vertical TFET offers 77% higher effective drive strength than Si-FinFET for given inverter standard cell area. Energy-delay performance of TFET shows gain over CMOS for low V-DD logic applications.

ID CHELONIA-MYDAS
AB Naturalists as early as Darwin observed terrestrial basking in green turtles (Chelonia mydas), but the distribution and environmental influences of this behaviour are poorly understood. Here, we examined 6 years of daily basking surveys in Hawaii and compared them with the phenology of local sea surface temperatures (SST). Data and models indicated basking peaks when SST is coolest, and we found this timeline consistent with bone stress markings. Next, we assessed the decadal SST profiles for the 11 global green turtle populations. Basking generally occurs when winter SST falls below 23 degrees C. From 1990 to 2014, the SST for these populations warmed an average 0.04 degrees C yr(-1) (range 0.01-0.09 degrees C yr(-1)); roughly three times the observed global average over this period. Owing to projected future warming at basking sites, we estimated terrestrial basking in green turtles may cease globally by 2100. To predict and manage for future climate change, we encourage a more detailed understanding for how climate influences organismal biology.

TI STATE OF THE CALIFORNIA CURRENT 2014-15: IMPACTS OF THE WARM-WATER

AB In 2014, the California Current (similar to 28 degrees-48 degrees N) saw average, or below average, coastal upwelling and relatively low productivity in most locations, except from 38 degrees-43 degrees N during June and July. Chlorophyll-a levels were low throughout spring and summer at most locations, except in a small region around 39 degrees N. Catches of juvenile rockfish (an indicator of upwelling-related fish species) remained high throughout the area surveyed (32 degrees-43 degrees N). In the fall of 2014, as upwelling ceased, many locations saw an unprecedented increase in sea surface temperatures (anomalies as large as 4 degrees C), particularly at 45 degrees N due to the coastal intrusion of an extremely anomalous pool of warm water. This warm surface anomaly had been building offshore in the Gulf of Alaska since the fall of 2013, and has been referred to as the "blob." Values of the Pacific Decadal Oscillation index (PDO) continued to climb during 2014, indicative of the increase in warm coastal surface waters, whereas the North Pacific Gyre Oscillation index (NPGO) saw a slight rebound to more neutral values (indicative of average productivity levels) during 2014. During spring 2015, the upwelling index was slightly higher than average for locations in the central and northern region, but remained below average at latitudes south of 35 degrees N. Chlorophyll a levels were slightly higher than average in similar to 0.5 degrees latitude patches north of 35 degrees N, whereas productivity and phytoplankton biomass were low south of Pt. Conception. Catches of rockfish remained high along most of the coast, however, market squid remained high only within the central coast (36 degrees-38 degrees N), and euphausiid abundance decreased everywhere, as compared to the previous year. Sardine and anchovy were nearly absent from the southern portion of the California Current system (CCS), whereas their larvae were found off the coast of Oregon and Washington during winter for the first time in many years. Waters warmed dramatically in the southern California region due to a change in wind patterns similar to that giving rise to the blob in the broader northeast Pacific. For most of the coast, there were intrusions of species never found before or found at much higher abundances than usual, including fish, crustaceans, tunicates and other gelatinous zooplankton, along with other species often indicative of an El Nino. Thus species richness was high in many areas given the close juxtaposition of coastal upwelling-related species with the offshore warm-water intrusive or El Nino-typical taxa. Thus the California Current by 2015 appears to have transitioned to a very different state than previous observations.

ID LINE SIMULATION CHARACTERISTICS; CLIMATE; FORMULATION
AB The world's major Eastern Boundary Currents (EBC) are critically important areas for global fisheries. Computational limitations have divided past EBC modeling into two types: high-resolution regional approaches that resolve the strong mesoscale structures involved; and coarse global approaches that represent the large-scale context for EBCs but crudely resolve only the largest scales of their local manifestation. These latter global studies have illustrated the complex mechanisms involved in the climate change and acidification response in these regions, with the EBC response dominated not by local adjustments but large-scale reorganization of ocean circulation through remote forcing of water mass supply pathways. While qualitatively illustrating the limitations of regional high-resolution studies in long-term projections, these studies lack the ability to robustly quantify change because of the inability of these models to represent the baseline mesoscale structures of EBCs. In the present work, we compare current generation coarse resolution (1 degrees) and a prototype next generation high-resolution (1/10 degrees) Earth System Models (ESMs) from NOAA's Geophysical Fluid Dynamics Laboratory in representing the four major EBCs. We review the long-known temperature biases that the coarse models suffer in being unable to represent the timing and intensity of upwelling-favorable winds. In promising contrast, we show that the high-resolution prototype is capable of representing not only the overall mesoscale structure in physical and biogeochemical fields, but also the appropriate offshore extent of temperature anomalies and other EBC characteristics. In terms of representation of large-scale circulation, results were mixed, with the high-resolution prototype addressing some, but not all, of the biases in the coarse-resolution ESM. The ability to simulate EBCs in the global context at high resolution in global ESMs represents a fundamental milestone towards both seasonal to interannual ecological forecasting and long-term projection of climate, ecosystem, and acidification baselines and sensitivity.

AB Rockfish Conservation Areas (RCAs) were implemented in 2000 to 2003 along the West Coast of the United States to reduce fishing mortality on rockfish (Sebastes spp.) and other groundfish species that had recently been declared overfished. In 2012, we initiated a study to compare recent catch rates, species compositions and length frequencies of fishes inside and outside the RCAs with data collected in central California between 1995 and 1998. At all sites surveyed, total catch rates from the new surveys (2012-14) were significantly higher than catch rates from before RCA implementation (1995-98). The majority of the differences were due to the increased relative abundance of yellowtail rockfish (Sebastes flavidus), although other species, including the overfished canary rockfish (Sebastes pinniger), also increased. Differences in the size composition of species between the two time periods reflected both the increased survival of older fishes and higher recruitment success in the past decade.

AB This study investigates the properties of the diurnal cycle of microwave brightness temperatures (TB), namely the phase and the amplitude, and their variability in time and space over the globe to infer information on key land surface parameters like changes in soil texture spatial distribution, soil moisture conditions, and vegetation density. The phase corresponds to the lag between Land Surface Temperature (LST) and TB diurnal cycles. The amplitude is determined as the difference between the maximum and the minimum of TB diurnal cycle. The diurnal cycle of TB was constructed using observations from the Advanced Microwave Scanning Radiometer-Earth Observing System (AMSR-E) and the Special Sensor Microwave/Imager (SSM/I). The latter offer a series of sensors, namely, F13, F14, and F15 that were used in this study for a higher temporal coverage and more accurate diurnal cycle determination. LST estimates, which are available every 3 h from the International Satellite Cloud Climatology Project (ISCCP) database were used to build the LST diurnal cycle. ISCCP LST data is an infrared-based temperature with almost no penetration and is the representative of top skin temperature.
The analyses of the diurnal cycles showed that the diurnal amplitude of TB decreases as the vegetation density increases, especially in the case of low frequencies which penetrate deeper into the canopy which makes them more sensitive to changes in vegetation density. The interannual variations of TB diurnal amplitudes were also in agreement with the seasonality of the vegetation cover. Over desert and rain forest regions where surface conditions do not vary significantly throughout the year, the changes in diurnal amplitudes were the lowest. A relationship between phase and amplitude values was established. It was found that the amplitude of TB diurnal cycle decreases when the phase lag increases. The spatial distribution of the determined diurnal properties, namely, phase and amplitude of TB, showed an agreement with lithology maps in desert areas. Lower TB amplitudes were observed over regions with loose siliceous rocks. Phase lag values between 1.5 and 3 h corresponded to 83% of the class "loose siliceous rocks'' in the Sahara Desert, which corroborates the potential of using the diurnal properties of TB as an indicator of land surface parameters.

AB An effective bias correction procedure using gauge measurement is a significant step for radar data processing to reduce the systematic error in hydrological applications. In these bias correction methods, the spatial matching of precipitation patterns between radar and gauge networks is an important premise. However, the wind-drift effect on radar measurement induces an inconsistent spatial relationship between radar and gauge measurements as the raindrops observed by radar do not fall vertically to the ground. Consequently, a rain gauge does not correspond to the radar pixel based on the projected location of the radar beam. In this study, we introduce an adjustment method to incorporate the wind-drift effect into a bias correlation scheme. We first simulate the trajectory of raindrops in the air using downscaled three-dimensional wind data from the weather research and forecasting model (WRF) and calculate the final location of raindrops on the ground. The displacement of rainfall is then estimated and a radar-gauge spatial relationship is reconstructed. Based on this, the local real-time biases of the bin-average radar data were estimated for 12 selected events. Then, the reference mean local gauge rainfall, mean local bias, and adjusted radar rainfall calculated with and without consideration of the wind-drift effect are compared for different events and locations. There are considerable differences for three estimators, indicating that wind drift has a considerable impact on the real-time radar bias correction. Based on these facts, we suggest bias correction schemes based on the spatial correlation between radar and gauge measurements should consider the adjustment of the wind-drift effect and the proposed adjustment method is a promising solution to achieve this.

AB A test chip to produce known and controllable gradients of surface potential and magnetic field at the chip surface and suitable for imaging with various types of scanning probe microscopes is presented. The purpose of the test chip is to evaluate various SPMs as metrology tools to image electromagnetic fields within nanoelectronic devices and multi -level interconnects, and as metrology tools to detect defects in back end of line (BEOL) metallization and packaging processes. Four different levels of metal are used to create different buried structures that, when biased, will produce varying electric field and magnetic field distributions. Contacts to the chip are made via wire bonds to a printed circuit board (PCB) that allows programed external biases and ground to be applied to specific metal levels while imaging with a SPM. DC and high frequency COMSOL simulations of the test structures were conducted to determine the expected field distributions. Electric field can be imaged via scanning Kelvin force microscopy (SKFM); magnetic field via scanning magnetic force microscopy (MFM); and the capacitance of buried metal lines via scanning microwave microscopy (SMM). The combination of precisely known structures and accurate simulations will allow the spatial resolution and accuracy of various SPMs sensitive to electric field (potential) or magnetic field to be determined and improved.

AB In 2011-12, a field study demonstrated that ribbed mussels from two locations in the north-east Atlantic Coast of the USA used different feeding strategies to adapt to widely differing seston characteristics and achieve the same absorption efficiency. To investigate whether there was local, genetic adaptation of mussels in the two contrasting sites, we conducted a transplant experiment in 2012 in which mussels were moved from the high-plankton, low-inorganic waters of Milford Harbor, CT, to the high-inorganic, low-plankton waters of Hunts Point, Bronx, NY. Results showed that mussels from Milford adapted to the new, poorer-quality seston within 6 days of submersion in Hunts Point waters, which indicates that phenotypic plasticity in the species is sufficient to account for adaptability of the ribbed mussel to Hunts Point conditions. This adaptability makes the ribbed mussel a good candidate for environmental remediation technologies, such as nutrient bioextraction.

AB Effective simulation of diurnal variability is an important aspect of many geophysical data assimilation systems. For the Martian atmosphere, thermal tides are particularly prominent and contribute much to the Martian atmospheric circulation, dynamics and dust transport. To study the Mars diurnal variability and Mars thermal tides, the Geophysical Fluid Dynamics Laboratory Mars Global Climate Model with the 4D-local ensemble transform Kalman filter (4D-LETKF) is used to perform an analysis assimilating spacecraft temperature retrievals. We find that the use of a 'traditional' 6-hr assimilation cycle induces spurious forcing of a resonantly enhanced semi-diurnal Kelvin waves represented in both surface pressure and mid-level temperature by forming a wave 4 pattern in the diurnal averaged analysis increment that acts as a 'topographic' stationary forcing. Different assimilation window lengths in the 4D-LETKF are introduced to remove the artificially induced resonance. It is found that short assimilation window lengths not only remove the spurious resonance, but also push the migrating semi-diurnal temperature variation at 50 Pa closer to the estimated 'true' tides even in the absence of a radiatively active water ice cloud parameterisation. In order to compare the performance of different assimilation window lengths, short-term to mid-range forecasts based on the hour 00 and 12 assimilation are evaluated and compared. Results show that during Northern Hemisphere summer, it is not the assimilation window length, but the radiatively active water ice clouds that influence the model prediction. A 'diurnal bias correction' that includes bias correction fields dependent on the local time is shown to effectively reduce the forecast root mean square differences between forecasts and observations, compensate for the absence of water ice cloud parameterisation and enhance Martian atmosphere prediction. The implications of these results for data assimilation in the Earth's atmosphere are discussed.

AB The variability of trace gases such as carbon monoxide (CO) at surface monitoring stations is affected by meteorological forcings that are particularly complicated over mountainous terrain. A detailed understanding of the impact of meteorological forcings on trace gas variability is challenging, but is vital to distinguish trace gas measurements affected by local pollutant sources from measurements representative of background mixing ratios. In the present study, we investigate the meteorological and CO characteristics at Pinnacles (38.61 N, 78.35 W, 1017m above mean sea level), a mountaintop monitoring site in northwestern Virginia, USA, in the Appalachian Mountains, from 2009 to 2012, and focus on understanding the dominant meteorological forcings affecting the CO variability on diurnal timescales. The annual mean diurnal CO cycle shows a minimum in the morning between 0700 and 0900 LST and a maximum in the late afternoon between 1600 and 2000 LST, with a mean (median) daily CO amplitude of 39.2 +/- 23.7 ppb (33.2 ppb). CO amplitudes show large day-to-day variability. The largest CO amplitudes, in which CO mixing ratios can change >100 ppb in >3 h, occur in the presence of synoptic disturbances. Under fair weather conditions, local-to regional-scale transport processes are found to be more important drivers of the diurnal CO variability. On fair weather days with northwesterly winds, boundary layer dilution causes a daytime CO decrease, resembling the variability observed atop tall towers in flat terrain. Fair weather days with a wind shift from the northwest to the south are characterised by an afternoon CO increase and resemble the variability observed at mountaintops influenced by the vertical transport of polluted air from adjacent valleys.

AB Desert dust (DD) aerosols reach the El Arenosillo observatory (southwest Spain) following two characteristic pathways at sea level, each showing significant differences in its aerosol microphysical and optical properties. These differences, in turn, determine the influence on the radiative forcing over the region. For these events, the meteorological scenarios show a depression located over North Africa at ground level. A Mediterranean pathway occurs when: (1) the depression is located over North Africa and the Mediterranean Basin or (2) it is coupled to a high pressure in higher latitudes. A North Africa pathway is observed when the depression is located only over North Africa. In our inventory, there are clear DD episodes under the Mediterranean flow, whereas other specific DD events take place under a mixture of Mediterranean and North African flows. The pure Mediterranean flow is associated with a higher increase of particle volume and scattering coefficient within the sub-micron than the super-micron size ranges. This result indicates that the contribution to the radiative forcing through the scattering processes over the region for particles with D < 1 mu m is larger than for particles with D < 1 mu m. In contrast, the episodes with a mixture of Mediterranean and North African flows show a similar effect of sub-and super-micron size ranges on radiative forcing. The size range with the largest impact on the scattering processes is 0.3 mu m < D < 0.6 mu m. Similar temporal variability of in situ and columnar-integrated aerosol properties on episodes with mixed flow suggests that the amounts of aerosols within the super-micron size range at the surface and aloft are correlated. During the episodes with pure Mediterranean flow, the amounts of aerosol vary independently within all size ranges, but the particle size distributions at surface and aloft are similar.

AB The use of in situ measurements is essential in the validation and evaluation of the algorithms that provide coastal water quality data products from ocean colour satellite remote sensing. Over the past decade, various types of ocean colour algorithms have been developed to deal with the optical complexity of coastal waters. Yet there is a lack of a comprehensive intercomparison due to the availability of quality checked in situ databases. The CoastColour Round Robin (CCRR) project, funded by the European Space Agency (ESA), was designed to bring together three reference data sets using these to test algorithms and to assess their accuracy for retrieving water quality parameters. This paper provides a detailed description of these reference data sets, which include the Medium Resolution Imaging Spectrometer (MERIS) level 2 match-ups, in situ reflectance measurements, and synthetic data generated by a radiative transfer model (HydroLight). These data sets, representing mainly coastal waters, are available from doi:10.1594/PANGAEA.841950.
The data sets mainly consist of 6484 marine reflectance (either multispectral or hyperspectral) associated with various geometrical (sensor viewing and solar angles) and sky conditions and water constituents: total suspended matter (TSM) and chlorophyll a (CHL) concentrations, and the absorption of coloured dissolved organic matter (CDOM). Inherent optical properties are also provided in the simulated data sets (5000 simulations) and from 3054 match-up locations. The distributions of reflectance at selected MERIS bands and band ratios, CHL and TSM as a function of reflectance, from the three data sets are compared. Match-up and in situ sites where deviations occur are identified. The distributions of the three reflectance data sets are also compared to the simulated and in situ reflectances used previously by the International Ocean Colour Coordinating Group (IOCCG, 2006) for algorithm testing, showing a clear extension of the CCRR data which covers more turbid waters.

AB Accurate assessment of anthropogenic carbon dioxide (CO2) emissions and their redistribution among the atmosphere, ocean, and terrestrial biosphere is important to better understand the global carbon cycle, support the development of climate policies, and project future climate change. Here we describe data sets and a methodology to quantify all major components of the global carbon budget, including their uncertainties, based on the combination of a range of data, algorithms, statistics, and model estimates and their interpretation by a broad scientific community. We discuss changes compared to previous estimates as well as consistency within and among components, alongside methodology and data limitations. CO2 emissions from fossil fuels and industry (E-FF) are based on energy statistics and cement production data, while emissions from land-use change (E-LUC), mainly deforestation, are based on combined evidence from land-cover-change data, fire activity associated with deforestation, and models. The global atmospheric CO2 concentration is measured directly and its rate of growth (G(ATM)) is computed from the annual changes in concentration. The mean ocean CO2 sink (S-OCEAN) is based on observations from the 1990s, while the annual anomalies and trends are estimated with ocean models. The variability in S-OCEAN is evaluated with data products based on surveys of ocean CO2 measurements. The global residual terrestrial CO2 sink (S-LAND) is estimated by the difference of the other terms of the global carbon budget and compared to results of independent dynamic global vegetation models forced by observed climate, CO2, and land-cover change (some including nitrogen-carbon interactions). We compare the mean land and ocean fluxes and their variability to estimates from three atmospheric inverse methods for three broad latitude bands. All uncertainties are reported as +/- 1 sigma, reflecting the current capacity to characterise the annual estimates of each component of the global carbon budget. For the last decade available (20052014), E-FF was 9.0 +/- 0.5 GtC yr(-1) E-LUC was 0.9 +/- 0.5 GtC yr(-1), GATM was 4.4 +/- 0.1 GtC yr(-1), S-OCEAN was 2.6 +/- 0.5 GtC yr(-1), and S LAND was 3.0 +/- 0.8 GtC yr(-1). For the year 2014 alone, E FF grew to 9.8 +/- 0.5 GtC yr(-1), 0.6% above 2013, continuing the growth trend in these emissions, albeit at a slower rate compared to the average growth of 2.2% yr(-1) that took place during 2005-2014. Also, for 2014, E-LUC was 1.1 +/- 0.5 GtC yr(-1), G(ATM) was 3.9 +/- 0.2 GtC yr(-1), S-OCEAN was 2.9 +/- 0.5 GtC yr(-1), and S-LAND was 4.1 +/- 0.9 GtC yr(-1). G(ATM) was lower in 2014 compared to the past decade (2005-2014), reflecting a larger S-LAND for that year. The global atmospheric CO2 concentration reached 397.15 +/- 0.10 ppm averaged over 2014. For 2015, preliminary data indicate that the growth in E-FF will be near or slightly below zero, with a projection of 0.6 [ range of 1.6 to C 0.5] %, based on national emissions projections for China and the USA, and projections of gross domestic product corrected for recent changes in the carbon intensity of the global economy for the rest of the world.
From this projection of E-FF and assumed constant E LUC for 2015, cumulative emissions of CO2 will reach about 555 +/- 55 GtC (2035 +/- 205 GtCO(2)) for 1870-2015, about 75% from E FF and 25% from E LUC. This living data update documents changes in the methods and data sets used in this new carbon budget compared with previous publications of this data set (Le Quere et al., 2015, 2014, 2013). All observations presented here can be downloaded from the Carbon Dioxide Information Analysis Center (doi: 10.3334/CDIAC/GCP_2015).

AB Micro-scaling cryogenic refrigerators, in particular the Joule-Thomson (JT) variety require very good information about heat transfer characteristics of the refrigerants flowing in the microchannels for optimal design and performance. The extremely low Reynolds flow is present in a micro JT cryocooler, the heat transfer characteristics at these conditions require investigation. There are numerous studies regarding heat transfer coefficient measurements of liquid flow in microchannels at/near ambient temperature and high Reynolds flow (Re>2000), that agree well with the conventional correlations. However, results from previous studies of gaseous flow in microchannels at low Reynolds flow (Re<1000) disagree with conventional theory. Moreover, the studies performed at cryogenic temperatures are quite limited in number. In this paper, the single-phase heat transfer coefficients and friction factors for nitrogen are measured at ambient and cryogenic temperatures. The hydraulic diameters for this study are 60, 110 and 180 mu m for circular microchannels. The Reynolds numbers varied from a very low value of 10 to 3000. The measured friction factors are comparable to those in macro-scale tubes. The experimental results of the heat transfer indicate that Nusselt numbers derived from measurements are significantly affected by axial conduction at low Reynolds flow (Re<500). The Nusselt numbers at high Reynolds flow (Re>1000) follow conventional theory. The detailed experiment, procedure, and measured results are presented in this paper and discussed regarding deviation from ideal theory at low Reynolds flow.

AB Service-oriented manufacturing systems need to be supported by formal reference models for effective service description, discovery, and composition. A reference model should evolve continuously throughout its lifecycle to respond to changing requirements. The objective of this work is to propose a formal process for collaborative and community-based reference-model evolution and identify the computational components required for effective model evolution. The main steps of the proposed process include service registration, vocabulary extraction, evolution triggering, change evaluation and approval, and change implementation. An important feature of the proposed process is the use of a Simple Knowledge Organization System (SKOS) thesaurus for the initial stages of knowledge elicitation and organization.

TI Research highlights: probing adsorbed organic coatings on nanoparticle
surfaces
SO ENVIRONMENTAL SCIENCE-NANO
LA English
DT Editorial Material
AB Organic coatings adsorbed at a nanoparticle surface, together with the system properties, change the physicochemical properties of the nanoparticle, thereby possibly modifying its behavior and interactions with its surroundings. A detailed understanding of the coating and system properties and their relationship to nanoparticle behavior is therefore of great interest across all fields of nanotechnology, from medical and industrial applications to environmental implications of nanomaterials. Here, we highlight three studies that probe the properties and interactions of a variety of coatings on nanoparticle surfaces. In one study, both surface characterization methods and modeling approaches are applied to assess the persistence of citrate capping agents on gold nanoparticles upon adsorption of thiol ligands in ethanol. The second highlighted study demonstrates a labeling method for spatial mapping of binding sites on proteins adsorbed to colloidal particles, providing information on the composition and orientation of the adsorbed proteins. Finally, we highlight research that characterizes the interaction of proteins with grafted polymer coatings on nanoparticles and relates the structure of the resulting adsorbed layer to observed biological effects. These three studies outline general methodologies applicable for coating characterization.

AB Hatchery spring Chinook Salmon Oncorhynchus tshawytscha from Parkdale Hatchery on the Hood River, Oregon, and Carson National Fish Hatchery (CNFH) on the Wind River, Washington, were reared under a common-garden experimental regime at CNFH over three consecutive brood years (2008-2010) to assess the effects of stock on smoltification and early male maturation. Rearing groups were monitored for size, percent solid (a surrogate for whole-body lipid), gill Na+,K+-ATPase activity, and rate of precocious maturation in males (i.e., age-2 minijack rate). Despite rearing of the stocks under identical conditions, the out-of-basin Hood River stock was significantly smaller throughout the study and at release as smolts, had lower whole-body lipid at release, and had lower gill Na+,K+-ATPase activity at release than the Carson stock; furthermore, the Hood River stock exhibited much higher mean minijack rates than the Carson stock (45% versus 23% of males). Using logistic regression, we demonstrated that the threshold size for initiation of early male maturation was significantly lower for the Hood River stock than for the Carson stock, suggesting a genetic basis for this life history difference. The present study highlights the importance of understanding how specific genotypes may respond differently to the unique environmental conditions in a given hatchery environment. These differences may in turn influence physiological and life history pathways that affect smolt-to-adult return rates and the demography of returning adults.

AB Uncertainty in ocean analysis methods and deficiencies in the observing system are major obstacles for the reliable reconstruction of the past ocean climate. The variety of existing ocean reanalyses is exploited in a multi-reanalysis ensemble to improve the ocean state estimation and to gauge uncertainty levels. The ensemble-based analysis of signal-to-noise ratio allows the identification of ocean characteristics for which the estimation is robust (such as tropical mixedlayer-depth, upper ocean heat content), and where large uncertainty exists (deep ocean, Southern Ocean, sea ice thickness, salinity), providing guidance for future enhancement of the observing and data assimilation systems.

AB The availability of GODAE Oceanview-type ocean forecast systems provides the opportunity to develop high-resolution, short-to medium-range coupled prediction systems. Several groups have undertaken the first experiments based on relatively unsophisticated approaches. Progress is being driven at the institutional level targeting a range of applications that represent their respective national interests with clear overlaps and opportunities for information exchange and collaboration. The applications include forecasting of the general circulation, hurricanes, extra-tropical storms, high-latitude weather and coastal air-sea interaction. In some cases, research has moved beyond case and sensitivity studies to controlled experiments to obtain statistically significant metrics and operational predictions.

TI GODAE OceanView Inter-comparison for the Australian Region
SO JOURNAL OF OPERATIONAL OCEANOGRAPHY
LA English
DT Article
ID CIRCULATION MODEL; SYSTEM; RESOLUTION; IMPACT
AB This paper compares the performance of short-range operational ocean forecasts, using 'observational space' metrics developed under GODAE OceanView (GOV). Best estimates (behind the real-time analysis) and forecasts are intercompared for the Australian region (0-50S, 90-180E) for 2013. Systems considered include those developed in Australia, France, Canada, United Kingdom and USA. Each system is compared to observations of along-track sea level anomaly, sea surface temperature observations from surface drifters and sub-surface Argo profiles of temperature and salinity. The UK operational system generally has the smallest errors for sea surface temperature and sea level anomaly for the Australian region. However, the French systems outperform others in sub-surface temperature and salinity for the region. Of the two products provided by the Australian centre, an ensemble based approach is found to perform better than the deterministic system, having higher skill and lower root mean square errors. Some of the 'better' results of systems can be attributed in part to the lack of independence of the reference observations; however the study does demonstrate the feasibility and robustness of GOV global ocean inter-comparison efforts for regional applications.

AB Operational ocean forecast systems provide routine marine products to an ever-widening community of users and stakeholders. The majority of users need information about the quality and reliability of the products to exploit them fully. Hence, forecast centres have been developing improved methods for evaluating and communicating the quality of their products. Global Ocean Data Assimilation Experiment (GODAE) OceanView, along with the Copernicus European Marine Core Service and other national and international programmes, has facilitated the development of coordinated validation activities among these centres. New metrics, assessing a wider range of ocean parameters, have been defined and implemented in real-time. An overview of recent progress and emerging international standards is presented here.

AB The advancement of Coastal Ocean Forecasting Systems (COFS) requires the support of continuous scientific progress addressing: (a) the primary mechanisms driving coastal circulation; (b) methods to achieve fully integrated coastal systems (observations and models), that are dynamically embedded in larger scale systems; and (c) methods to adequately represent air-sea and biophysical interactions. Issues of downscaling, data assimilation, atmosphere-wave-ocean couplings and ecosystem dynamics in the coastal ocean are discussed. These science topics are fundamental for successful COFS, which are connected to evolving downstream applications, dictated by the socioeconomic needs of rapidly increasing coastal populations.

AB Recent advances in Coastal Ocean Forecasting Systems (COFS) are discussed. Emphasis is given to the integration of the observational and modeling components, each developed in the context of monitoring and forecasting in the coastal seas. These integrated systems must be linked to larger scale systems toward seamless data sets, nowcasts and forecasts (from the global ocean, through the continental shelf and to the nearshore regions). Emerging capabilities include: methods to optimize coastal/regional observational networks; and probabilistic approaches to address both science and applications related to COFS. International collaboration is essential to exchange best practices, achieve common frameworks and establish standards.

AB The paper gives an overview of the development of satellite oceanography over the past five years focusing on the most relevant issues for operational oceanography. Satellites provide key essential variables to constrain ocean models and/or serve downstream applications. New and improved satellite data sets have been developed and have directly improved the quality of operational products. The status of the satellite constellation for the last five years was, however, not optimal. Review of future missions shows clear progress and new research and development missions with a potentially large impact for operational oceanography should be demonstrated. Improvement of data assimilation techniques and developing synergetic use of high resolution satellite observations are important future priorities.

AB The GODAE-OceanView collection of papers primarily concerns the development of ocean data-assimilation models for operational oceanography. However, these models cannot function without a secure supply of in situ ocean data in near real-time. Several projects and programmes supply such data. The purpose of this paper is to review these data sources and describe the history, present status, future and robustness of these programmes. The conclusion is that though challenges continue with some components of the Global Ocean Observing System, overall the system continues to evolve and improve. The data are available in real-time to drive assimilation models, and expectations are increasing for more observational data. The prospects for the next 10 years seem to be good. All of the systems are evolving and there is little doubt that the Global Ocean Observing System will look different 10 years from now as new technologies emerge and capabilities improve.

AB The value of global (e.g. altimetry, satellite sea-surface temperature, Argo) and regional (e.g. radars, gliders, instrumented mammals, airborne profiles and biogeochemical) observation-types for monitoring the mesoscale ocean circulation and biogeochemistry is demonstrated using a suite of global and regional prediction systems and remotely-sensed data. A range of techniques is used to demonstrate the value of different observation-types to regional systems and the benefit of high-resolution and adaptive sampling for monitoring the mesoscale circulation. The techniques include Observing System Experiments, Observing System Simulation Experiments, adjoint sensitivities, representer matrix spectrum, observation footprints and spectral analysis. It is shown that local errors in global and basin-scale systems can be significantly reduced when assimilating observations from regional observing systems.

TI GODAE OceanView Class 4 forecast verification framework: global ocean
inter-comparison
SO JOURNAL OF OPERATIONAL OCEANOGRAPHY
LA English
DT Article
ID SYSTEM; MODEL; TEMPERATURE; CIRCULATION
AB As part of the work of the GODAE OceanView Inter-comparison and Validation Task Team (IV-TT), 6 global ocean forecasting systems spread across 5 operational oceanography forecast centres were inter-compared using a common set of observations as a proxy for the truth. The `Class 4' in the title refers to a set of forecast verification metrics defined in the MERSEA-IP/GODAE internal metrics document (Hernandez 2007), the defining feature of which is that comparisons between forecasts and observations take place in observation space. This approach is seen as a departure from other diagnostic approaches such as analysing model trends or innovation statistics, and is commonly used in the atmospheric community. The physical parameters involved in the comparison are sea surface temperature (SST), sub-surface temperature, sub-surface salinity and sea level anomaly (SLA). SST was measured using in-situ observations obtained from USGODAE, sub-surface conditions were compared to Argo profiles, while sea level anomaly was measured by several satellite altimeters courtesy of AVISO. The 5 forecast centres involved in the project were Met Office, Australian Bureau of Meteorology, Mercator Ocean, Environment Canada and NOAA/NWS/NCEP. Combining Met Office, Mercator Ocean and Environment Canada forecasts into a mixed resolution multi-model ensemble produces estimates of the ocean state which have better accuracy and associativity properties for SST, SLA and temperature profiles than any individual ensemble component.

AB The marine environment plays an increasingly important role in shaping economies and infrastructures, and touches upon many aspects of our lives, including food supplies, energy resources, national security and recreational activities. Global Ocean Data Assimilation Experiment (GODAE) and GODAE OceanView have provided platforms for international collaboration that significantly contribute to the scientific development and increasing uptake of ocean forecasting products by end users who address societal issues such as those listed above. Many scientific challenges and opportunities remain to be tackled in the ever-changing field of operational oceanography, from the observing system to modelling, data assimilation and product dissemination. This paper provides a brief overview of past achievements in GODAE OceanView, but subsequently concentrates on the future scientific foci of GODAE OceanView and its Task Teams, and provides a vision for the future of ocean forecasting.

AB Operational evolution of global and regional ocean forecasting systems has been extremely significant in recent years. Global Ocean Data Assimilation Experiment (GODAE) Oceanview supports the national research groups providing them with coordination and sharing expertise among the partners. Several systems have been set up and developed pre-operationally, and the majority of these are now fully operational; at the present time, they provide medium-and long-term forecasts of the most relevant ocean physical variables. These systems are based on ocean general circulation models and data-assimilation techniques that are able to correct the model with the information inferred from different types of observations. A few systems also incorporate a biogeochemical component coupled with the physical system, while others are based on coupled ocean-wave-ice-atmosphere models. The products are routinely validated with observations in order to assess their quality. Data and product implementation and organization, as well as service, for users have been well tried and tested, and most of the products are now available to users. The interaction with different users is an important factor in the development process. This paper provides a synthetic overview of the GODAE OceanView prediction systems.

DE colour rendering; colour preference; chroma saturation; perception;

AB Colour Rendering Index (CRI) often does not correlate well with visual evaluation of colour rendering of light sources at real illuminated scenes. The main reason is that CRI measures colour fidelity, while general users judge colour rendering based on their preference of object colour appearance, thus there is a need for a colour- preference based metric. Colour preference is mainly affected by saturation of object chroma. To obtain data for such colour preference evaluation, a series of vision experiments have been conducted using the NEST Spectrally Tunable Lighting Facility simulating an interior room, where 20 subjects viewed various fruits, vegetables, and their skin tones, under illumination of varied saturation levels at correlated colour temperatures (CCT) of 2700 K, 3500 K, and 5000 K. The results of the experiment show that subjects' preference is consistently peaked at saturation level of Delta C-ab* approximate to 5 at all CCT conditions and for all target objects. The results may be useful to develop a colour preference metric.

AB Sintered PTFE is an extremely stable, near-perfect Lambertian reflecting diffuser and calibration standard material that has been used by national labs, space, aerospace and commercial sectors for over two decades. New uncertainty targets of 2% on-orbit absolute validation in the Earth Observing Systems community have challenged the industry to improve is characterization and knowledge of almost every aspect of radiometric performance (space and ground). Assuming "near perfect" reflectance for angular dependent measurements is no longer going to suffice for many program needs. The total hemispherical spectral reflectance provides a good mark of general performance; but, without the angular characterization of bidirectional reflectance distribution function (BRDF) measurements, critical data is missing from many applications and uncertainty budgets. Therefore, traceable BRDF measurement capability is needed to characterize sintered PTFE's angular response and provide a full uncertainty profile to users. This paper presents preliminary comparison measurements of the BRDF of sintered PTFE from several laboratories to better quantify the BRDF of sintered PTFE, assess the BRDF measurement comparability between laboratories, and improve estimates of measurement uncertainties under laboratory conditions.

AB The Advanced Baseline Imager (ABI) will be aboard the National Oceanic and Atmospheric Administration's Geostationary Operational Environmental Satellite R-Series (GOES-R) to supply data needed for operational weather forecasts and long-term climate variability studies, which depend on high quality data. Unlike the heritage operational GOES systems that have two or four detectors per band, ABI has hundreds of detectors per channel requiring calibration coefficients for each one. This increase in number of detectors poses new challenges for next generation sensors as each detector has a unique spectral response function (SRF) even though only one averaged SRF per band is used operationally to calibrate each detector. This simplified processing increases computational efficiency. Using measured system-level SRF data from pre-launch testing, we have the opportunity to characterize the calibration impact using measured SRFs - both per detector and as an average of detector-level SRFs similar to the operational version. We calculated the spectral response impacts for the thermal emissive bands (TEB) theoretically, by simulating the ABI response viewing an ideal blackbody and practically, with the measured ABI response to an external reference blackbody from the pre-launch TEB calibration test. The impacts from the practical case match the theoretical results using an ideal blackbody. The observed brightness temperature trends show structure across the array with magnitudes as large as 0.1 K for band 12 (9.61 mu m), and 0.25 K for band 14 (11.2 mu m) for a 300 K blackbody. The trends in the raw ABI signal viewing the blackbody support the spectral response measurements results, since they show similar trends in bands 12 (9.61 mu m), and 14 (11.2 mu m), meaning that the spectral effects dominate the response differences between detectors for these bands. We further validated these effects using the radiometric bias calculated between calibrations using the external blackbody and another blackbody, the ABI on-board calibrator. Using the detector-level SRFs reduces the structure across the arrays but leaves some residual bias. Further understanding of this bias could lead to refinements of the blackbody thermal model. This work shows the calibration impacts of using an average SRF across many detectors instead of accounting for each detector SRF independently in the TEB calibration. Note that these impacts neglect effects from the spectral sampling of Earth scene radiances that include atmospheric effects, which may further contribute to artifacts post-launch and cannot be mitigated by processing with detector-level SRFs. This study enhances the ability to diagnose anomalies on-orbit and reduce calibration uncertainty for improved system performance.

ID LIGHT; SATELLITE
AB The Day/Night Band (DNB) of the Visible Infrared Imaging Radiometer Suite (VIIRS) onboard Suomi-NPP represents a major advancement in night time imaging capabilities. The DNB senses radiance that can span 7 orders of magnitude in one panchromatic (0.5-0.9 am) reflective solar band and provides imagery of clouds and other Earth features over illumination levels ranging from full sunlight to quarter moon. When the satellite passes through the day-night terminator, the DNB sensor is affected by stray light due to solar illumination on the instrument. With the implementation of stray light correction, stray light-corrected DNB images enable the observation of aurora occurred in the high latitude regions during geomagnetic storms. In this paper, DNB observations of auroral activities are analyzed during a long period (>20 hours) of geomagnetic storm event occurred on Apr. 29-30, 2014. The storm event has the B, component of interplanetary magnetic field (IMF) pointing southward for more than 20 hours. During this event, the geomagnetic storm index Dst reached -67 nT and the geomagnetic auroral electrojet (AE) index increased and reached as high as 1200 nT with large amplitude fluctuations. The event occurred during new moon period and DNB observation has minimum moon light contamination. During this event, auroras are observed by DNB for each orbital pass on the night side (similar to local time 1:30am) in the southern hemisphere. DNB radiance data are processed to identify regions of aurora during each orbital pass. The evolution of aurora is characterized with time series of the poleward and equatorward boundary of aurora, area, peak radiance and total light emission of the aurora in DNB observation. These characteristic parameters are correlated with solar wind and geomagnetic index parameters. It is found that the evolution of total area-integrated radiance of auroral region over the southern hemisphere correlated well with the ground geomagnetic AE index with correlation coefficient = 0.71. DNB observations of aurora help understand the relations among solar wind variation, auroral activities and geomagnetic responses.

AB Radiometric stability of the lunar surface, its lack of atmosphere and smooth reflectance spectrum makes the moon an ideal target for calibrating satellite-based multi-band imagers. Lunar calibration for solar bands has been an important part of trending the radiometric performance of GOES imager. The lunar disk-equivalent irradiance has been often used to trend the on-orbit degradation of the GOES imager and its performance is largely affected by the uncertainties embedded in the lunar irradiance model in characterizing its dependence on lunar phase and libration. On the other hand, the lunar view by GOES imager provides opportunity to perform radiometric calibration of GOES imager using lunar radiances of selected locations on the moon. In order to do so, lunar observations by GOES need to be mapped onto selenographic coordinate, i.e. latitude and longitude in moon-centered coordinate. In this paper, algorithms and procedures are developed to map lunar images observed by GOES onto selenographic coordinate. Progressive shift in east-west scan direction, oversampling factor and distortion of lunar image are corrected to transform it back to be within a circular disk. Controlling region matching is applied to determine rotation angle and three consecutive rotations are performed to map lunar observation onto selenographic coordinate. Lunar observations of GOES-12 are processed and regions of interest (ROIs) are identified. Lunar phase-dependence of lunar measurements at ROIs is analyzed. It is found that lunar measurement depends strongly on Sun-Moon-Satellite geometry and knowledge of BRDF of lunar surface can enable trending of radiometric performance of GOES imager with local lunar radiance.

AB The development of targets is foundational in conservation. Although progress has been made in setting targets, the diverse linkages among ecological and social components make target setting for coupled social-ecological systems extremely challenging. Developing integrated social-ecological targets is difficult because it forces policy makers to consider how management actions propagate throughout social-ecological systems, and because ultimately it is society, not scientists, that defines targets. We developed an interdisciplinary approach for identifying management targets and illustrate this approach using an example motivated by Puget Sound, USA. Our approach blends ecological modeling with empirical social science to articulate trade-offs and reveal societal preferences for different social-ecological states. The framework aims to place information in the hands of decision makers and promote discussion in the appropriate forums. Our ultimate objective is to encourage the informed participation of citizens in the development of social-ecological targets that reflect their values while also protecting key ecosystem attributes.

Such problems arise in a variety of applications such as the computation of the eigenvectors of a matrix corresponding to a known eigenvalue. The method is based on elementary linear algebra combined with the observation that if the matrix is rank-k deficient, then a random rank-k perturbation yields a nonsingular matrix with probability close to 1.

AB Here we review the population, community, and evolutionary consequences of marine reserves. Responses at each level depend on the tendency of fisheries to target larger body sizes and the tendency for greater reserve protection with less movement within and across populations. The primary population response to reserves is survival to greater ages and sizes plus increases in the population size for harvested species, with greater response to reserves that are large relative to species' movement rates. The primary community response to reserves is an increase in total biomass and diversity, with the potential for trophic cascades and altered spatial patterning of metacommunities. The primary evolutionary response to reserves is increased genetic diversity, with the theoretical potential for protection against fisheries-induced evolution and selection for reduced movement. The potential for the combined outcome of these responses to buffer marine populations and communities against temporal environmental heterogeneity has preliminary theoretical and empirical support.

AB A comprehensive suite of instruments was used to quantify the emissions of over 200 organic gases, including methane and volatile organic compounds (VOCs), and 9 inorganic gases from 56 laboratory burns of 18 different biomass fuel types common in the southeastern, southwestern, or northern US. A gas chromatograph-mass spectrometry (GC-MS) instrument provided extensive chemical detail of discrete air samples collected during a laboratory burn and was complemented by real-time measurements of organic and inorganic species via an open-path Fourier transform infrared spectroscopy (OP-FTIR) instrument and three different chemical ionization-mass spectrometers. These measurements were conducted in February 2009 at the US Department of Agriculture's Fire Sciences Laboratory in Missoula, Montana and were used as the basis for a number of emission factors reported by Yokelson et al. (2013). The relative magnitude and composition of the gases emitted varied by individual fuel type and, more broadly, by the three geographic fuel regions being simulated. Discrete emission ratios relative to carbon monoxide (CO) were used to characterize the composition of gases emitted by mass; reactivity with the hydroxyl radical, OH; and potential secondary organic aerosol (SOA) precursors for the 3 different US fuel regions presented here. VOCs contributed less than 0.78% +/- 0.12% of emissions by mole and less than 0.95% +/- 0.07% of emissions by mass (on average) due to the predominance of CO2, CO, CH4, and NOx emissions; however, VOCs contributed 70-90 (+/- 16)% to OH reactivity and were the only measured gas-phase source of SOA precursors from combustion of biomass. Over 82% of the VOC emissions by mole were unsaturated compounds including highly reactive alkenes and aromatics and photolabile oxygenated VOCs (OVOCs) such as formaldehyde. OVOCs contributed 57-68% of the VOC mass emitted, 41-54% of VOC-OH reactivity, and aromatic-OVOCs such as benzenediols, phenols, and benzaldehyde were the dominant potential SOA precursors. In addition, ambient air measurements of emissions from the Fourmile Canyon Fire that affected Boulder, Colorado in September 2010 allowed us to investigate biomass burning (BB) emissions in the presence of other VOC sources (i.e., urban and biogenic emissions) and identify several promising BB markers including benzofuran, 2-furaldehyde, 2-methylfuran, furan, and benzonitrile.

AB The identification of atmospheric CO2 observation data which are minimally influenced by very local emissions/removals is essential for trend analysis, for the estimation of regional sources and sinks, and for the modeling of long-range transport of CO2. In this study, four approaches are used to filter the atmospheric CO2 observation records from 2009 to 2011 at one World Meteorological Organization/Global Atmosphere Watch (WMO/GAW) regional station (Lin'an, LAN) in China. The methods are based on the concentration of atmospheric black carbon (BC), on a statistical approach (robust extraction of baseline signal, REBS), on CH4 as an auxiliary tracer (AUX), and on meteorological parameters (MET). All approaches do suitably well to capture the seasonal CO2 cycle at LAN. Differences are observed in the average regional mole fractions with annual values in the REBS method at least 1.7 +/- 0.2 ppm higher than the other methods. The BC method may underestimate the regional CO2 mole fractions during the winter-spring period and should be treated with caution. The REBS method is a purely statistical method and it may also introduce errors on the regional CO2 mole fraction evaluations, as the filtered trend may be influenced by the "noisy" raw data series. Although there are correlations between CH4 and CO2 mole fractions at LAN, the different source/sink regimes may introduce bias on the regional CO2 estimation in the AUX method, typically in summer. Overall, the MET method seems to be the most favorable because it mainly focuses on the influence of potential local sources and sinks, and considers diurnal variations and meteorological conditions. Using the MET method, the annual growth rate of regional CO2 at LAN is determined to be 3.1 +/- 0.01 ppm yr(-1) (standard error) from 2009 to 2011.

AB In the past 10 to 15 years, excessive growth of Cladophora and other attached algae in the nearshore regions of Lake Michigan has re-emerged as an important resource management issue. This paper considers the question, "What information is needed to predict the response of Cladophora production in Lake Michigan to management variables, such as nutrient loading, and to additional environmental variables that are outside of management control?" Focusing on Lake Michigan, while drawing on the broader literature, we review the current state of information regarding 1) models of Cladophora growth, 2) models that simulate the physical environment, 3) models that simulate nearshore and whole-lake nutrient dynamics, with a specific focus on the role of dreissenid mussels, and 4) monitoring of Cladophora abundance. We conclude that while substantial progress has been made, considerable additional research is required before reliable forecasts of Cladophora response to nutrient loads and other environmental variables are possible. By providing a detailed outline of this complex, multidisciplinary problem, we hope that this paper will aid in coordinating collaborative research efforts toward the development of useful predictive models.

AB Currently little is known about the condition and spawning patterns of quagga mussels (Dreissena rostriformis bugensis) in deeper, consistently cold regions of the Great Lakes. This lack of information limits our ability to predict the future expansion of D. r. bugensis in the offshore regions of the Great Lakes and other large, deep lakes. We collected quagga mussels on a monthly basis in 2013 (April-September) at three established sites along a depth transect (25, 45, and 93 m) in southern Lake Michigan and calculated a condition index (CI), a ratio of dry soft tissue weight to internal shell capacity, to assess condition, and a gametogenic index to assess reproductive activity. We also measured size-frequency, density, and biomass in March, July, and October. Condition was consistently highest at 25 m, population biomass and average shell length were highest at 45 m, and density was highest at 93 m. At all three depths, Cl decreased with increasing shell length suggesting that food availability may be limiting for larger individuals. Mussels at 45 m spawned earliest with over 50% spent by July while mussels at 93 m began spawning in August. Mussels at 25 m had not yet spawned by September. Long-term trends in density indicate that D. r. bugensis populations continued to expand at the 93 m site but may be stabilizing at 25 m and 45 m. Consistent with density trends, CI at 25 m and 45 m was lower than in 2004 and 2008. (C) 2015 International Association for Great Lakes Research. Published by Elsevier B.V. All rights reserved.

AB The disappearance of the spring phytoplankton bloom in Lake Michigan has been attributed in some studies to the direct effect of quagga mussel filter-feeding. We applied a biophysical model to test whether the observed reduction in the spring bloom can be explained by direct effects of quagga mussel grazing. We developed a 1-D column biological model that simulated light and temperature limitation on phytoplankton growth, vertical mixing, and grazing by zooplankton and quagga mussels. We applied the 3-D finite volume coastal ocean model (FVCOM) to provide vertical mixing, with two scenarios of atmospheric forcing: (a) North American Regional Reanalysis (NARR) and (b) station interpolation using the Natural Neighbor Method. Simulated development of the spring bloom and formation of the deep chlorophyll layer in the early summer stratified period were consistent with observations. Increased strength of winter stratification (surface <4 degrees C) in 1997 (cold spring) increased chlorophyll concentrations during March and April, compared to 1998, by reducing light limitation (reduced mixed-layer depth). Simulations with NARR forcing produced high-biased chlorophyll, resulting from low-biased wind speed and spring mixed layer depth. Simulated mussel filter feeding strongly reduced phytoplankton abundance when the water column was mixed to the bottom, but had little effect during periods of summer and winter stratification. These model simulations highlight the sensitivity of both phytoplankton growth and the impact of profundal quagga mussel filter-feeding to vertical mixing and stratification, which in turn is controlled by meteorological conditions.

AB The Lake Michigan ecosystem has undergone numerous, systemic changes (reduced nutrient, changing climate, invasive mussels) that have altered portions of the food web and thus, appear to have changed the lake's trophic state. That said, little is known about the components of the microbial food web (MFW, heterotrophic and phototrophic pico, nano, and micro-plankton), which we hypothesized have compensated as a food source for crustacean zooplankton given the recent declines in the biomass of large phytoplankton (mainly diatoms). Therefore, we measured the abundance of the entire MFW using complementary microscopic techniques, flow cytometry, and size fractionated chlorophyll concentrations at sites in northern and southern Lake Michigan, and one site in Lake Superior; the latter site served as a benchmark for oligotrophic conditions. In addition, a historic comparison was made between 1987 and 2013 for the southern Lake Michigan site. Ppico numbers (i.e., picocyanobacteria) in 2013 were lower compared with those in the 1980s; however, the percent contribution of the <2 mu m fraction increased 2-fold (>50% of total chlorophyll). The abundance of small, pigmented chrysomonads and cryptomonads (Pnano size category) was not significantly different between 1987 and 2013 at the same time Pmicro did decline; this shift towards Ppico and Pnano dominance may be related to the recent oligotrophication of Lake Michigan. The abundance of ciliated protists (Hmicro size class) was 3-fold lower in 2013 compared with levels in 1987, while the abundance of both Hpico (eubacteria, range 0.24-1.36 x 10(6) cells mL(-1)) and Hnano (mainly colorless chrysomonads; range 0.11-6.4 x 10(3) cells mL(-1)) remained stable and reflected the resilience of bacteria-flagellate trophic linkage.

AB Zooplankton were collected at a nearshore (15 m depth), a mid-depth (45 m) and an offshore site (110 m) near Muskegon, Michigan during March-December in 2007-2012. On a volumetric basis, biomass was lower at the nearshore site relative to the mid-depth site, but overall biomass at the nearshore and offshore sites did not differ. Differences in zooplankton assemblages among sites were due largely to Diaptomidae, Limnocalanus macrurus, Daphnia galeata mendotae, Cyclops, and either Bosmina longirostris or Bythotrephes longimanus. Diaptomidae were the most abundant group, accounting for 56-66% of zooplankton biomass across sites. Herbivorous cladocerans accounted for 14-22% of zooplankton biomass across sites, with B. longirostris dominant at the nearshore site and D. g. mendotae dominant at the mid-depth and offshore sites. Bythotrephes was the most abundant predatory cladoceran at all sites although, at the nearshore site, it was only abundant in the fall. There was a higher percentage of large-bodied zooplankton groups in the offshore and mid-depth zones relative to the nearshore zone. Declines in zooplankton biomass relative to the 1970s have occurred across all sites. In addition to seasonal variation within a site, we noted annual variation, especially at the offshore site, with the zooplankton assemblage during 2007-2008 differing from that found in 2010-2012 due to increases in D. g. mendotae and Cyclops and decreases in B. longimanus and L. macrurus in 2010-2012.

AB We analyze six years of survey data in Lake Michigan, which spanned large ranges in the abundance of the invasive predatory cladoceran Bythotrephes, to quantify the effect of this predator on the daytime vertical distribution of the nine most common species and life stages of Lake Michigan zooplankton. We found that Bythotrephes abundance and hypolimnion depth explained almost 50% of the variation in the vertical distribution of many zooplankton. Bythotrephes abundance was associated with significant and large (approximately 5-11 m) depth increases in cladocerans Daphnia and Bosmina, adult and copepodite stages of cyclopoid copepods, and adult diaptomid copepods Leptodiaptomus minutus, and Leptodiaptomus ashlandi; but did not significantly affect the depth of copepod nauplii, diaptomid copepodites, and adult Leptodiaptomus sicilis. Whereas other environmental factors, such as light attenuation coefficient, epilimnion and hypolimnion temperature, and sampling date significantly influenced the depth of various species and life stages, the inclusion of such environmental factors into linear models did not significantly lower the predicted influence of Bythotrephes. These results suggest that Bythotrephes abundance has a significant and large influence on the vertical distribution of a large component of the zooplankton assemblage in Lake Michigan. We argue that this pattern is driven by a Bythotrephes-induced anti-predator response in zooplankton prey. Such effects could lead to widespread growth costs to the zooplankton assemblage due to the colder water temperatures experienced at greater depths, which could in turn affect the rapidly changing Lake Michigan food web.

AB A plankton survey system, fisheries acoustics, and opening/closing nets were used to define fine-scale diel vertical spatial interactions among non-indigenous alewives and visually preying cercopagids (Bythotrephes longimanus and Cercopagis pengoi) and indigenous zooplankton in nearshore and offshore Lake Michigan during August 2004. Because of increased water clarity associated with dreissenid mussel expansion and radically different thermal structure between cruises, we were able to observe the effects of thermal structure on diel vertical migration under high light conditions favorable especially to visual predation by cercopagids. Vertical position and overlap between alewives, Bythotrephes, and Daphnia mendotae at a 60-m site were strongly driven by thermal structure. Daphnia showed the strongest diel vertical migration of zooplankton that included migration between the epilimnion at night and the metalimnion-hypolimnion boundary during the day, whereas its major predator, Bythotrephes, was confined at all times to the epilimnion-metalimnion. Some alewives migrated from the hypolimnion to the metalimnion and epilimnion at night As a result, most spatial overlap of Daphnia, Bythotrephes, and alewives occurred at night. Simple bioenergetics models were used to contrast predatory interactions between alewives and cercopagids at nearshore and offshore sites. Bythotrephes was the preferred prey of alewives, and at the 10-m site, alewives were the major controller of zooplankton because of its elimination of Bythotrephes. In contrast, Bythotrephes offshore likely escaped predation because of low spatial overlap with a low concentration of alewives and was the major predator and shaper of zooplankton community structure.

AB Offshore-onshore spatial distribution and abundance of Cercopagis pengoi, a small non-indigenous predatory cercopagid, in Lake Michigan have been hypothesized to be regulated by the larger non-indigenous predatory cercopagid, Bythotrephes longimanus, through predation and/or competition. However, temperature and prey abundance are other factors that could be affecting Cercopagis. First, we examined all these factors on Cercopagis population abundance, life history traits and spatio-temporal distribution. In addition, we examined vertical spatial overlap between these species and determined predation rate of Bythotrephes on Cercopagis. Linear mixed effects analysis of spatial-temporal data showed that biomass of B. longimanus had the strongest effect, which was significantly negative on biomass, proportion of fecund females and mean clutch size of Cercopagis. Fecundity increased significantly with density of potential prey zooplankton, whereas Cercopagis total biomass increased significantly with the mean epilimnion temperature. Cercopagis and Bythotrephes overlapped vertically in the epi- and metalimnion, and neither of them showed any appreciable diel vertical migration. In predation experiments, Bythotrephes consumed Cercopagis at the same rate as Daphnia mendotae, a known preferred prey, when offered at equal concentrations. Overall, this observation, together with vertical overlap of Cercopagis with Bythotrephes implies that Bythotrephes predation has a strong influence on Cercopagis distribution; however, prey availability, temperature, and competition may be important secondary factors. These results imply that invasion success of Cercopagis may be limited by prior invasion by Bythotrephes. (C) 2015 International Association for Great Lakes Research. Published by Elsevier B.V.

AB Using various available time series for Lake Michigan, we examined changes in the Lake Michigan food web following the dreissenid mussel invasions and identified those changes most likely attributable to these invasions, thereby providing a synthesis. Expansion of the quagga mussel (Dreissena rostriformis bugensis) population into deeper waters, which began around 2004, appeared to have a substantial predatory effect on both phytoplankton abundance and primary production, with annual primary production in offshore (>50 m deep) waters being reduced by about 35% by 2007. Primary production likely decreased in nearshore waters as well, primarily due to predatory effects exerted by the quagga mussel expansion. The drastic decline in Diporeia abundance in lake Michigan during the 1990s and 2000s has been attributed to dreissenid mussel effects, but the exact mechanism by which the mussels were negatively affecting Diporeia abundance remains unknown. In turn, decreased Diporeia abundance was associated with reduced condition, growth, and/or energy density in alewife (Alosa pseudoharengus), lake whitefish (Coregonus clupeaformis), deepwater sculpin (Myoxocephalus thompsonii), and bloater (Coregonus hoyi). However, lake-wide biomass of salmonines, top predators in the food web, remained high during the 2000s, and consumption of alewives by salmonines actually increased between the 1980-1995 and 1996-2011 time periods. Moreover, abundance of the lake whitefish population, which supports Lake Michigan's most valuable commercial fishery, remained at historically high levels during the 2000s. Apparently, counterbalancing mechanisms operating within the complex Lake Michigan food web have enabled salmonines and lake whitefish to retain relatively high abundances despite reduced primary production.

AB Standard blue-green ratio algorithms do not usually work well in turbid productive waters because of the contamination of the blue and green bands by CDOM absorption and scattering by non-algal particles. One of the alternative approaches is based on the two- or three band ratio algorithms in the red/NIR part of the spectrum, which require 665, 708, 753 nm bands (or similar) and which work well in various waters all over the world. The critical 708 nm band for these algorithms is not available on MODIS and VIIRS sensors, which limits applications of this approach. We report on another approach where a combination of the 745nm band with blue-green-red bands was the basis for the new algorithms. A multi-band algorithm which includes ratios Rrs(488)/Rrs(551) and Rrs(671)/Rrs(745) and two band algorithm based on Rrs671/Rrs745 ratio were developed with the main focus on the Chesapeake Bay (USA) waters. These algorithms were tested on the specially developed synthetic datasets, well representing the main relationships between water parameters in the Bay taken from the NASA NOMAD database and available literature, on the field data collected by our group during a 2013 campaign in the Bay, as well as NASA SeaBASS data from the other group and on matchups between satellite imagery and water parameters measured by the Chesapeake Bay program. Our results demonstrate that the coefficient of determination can be as high as R-2 > 0.90 for the new algorithms in comparison with R-2 = 0.6 for the standard OC3V algorithm on the same field dataset. Substantial improvement was also achieved by applying a similar approach (inclusion of Rrs(667)/Rrs(753) ratio) for MODIS matchups. Results for VIIRS are not yet conclusive.

AB The dynamic evolution of nanocatalyst particle shape and carbon composition during the initial stages of single-walled carbon nanotube growth by chemical vapor deposition synthesis is investigated. Classical reactive and ab initio molecular dynamics simulations are used, along with environmental transmission electron microscope video imaging analyses. A clear migration of carbon is detected from the nanocatalyst-substrate interface, leading to a carbon gradient showing enrichment of the nanocatalyst layers in the immediate vicinity of the contact layer. However, as the metal nanocatalyst particle becomes saturated with carbon, a dynamic equilibrium is established, with carbon precipitating on the surface and nucleating a carbon cap that is the precursor of nanotube growth. A carbon composition profile decreasing towards the nanoparticle top is clearly revealed by the computational and experimental results that show a negligible amount of carbon in the nanoparticle region in contact with the nucleating cap. The carbon composition profile inside the nanoparticle is accompanied by a welldefined shape evolution of the nanocatalyst driven by the various opposing forces acting upon it both from the substrate and from the nascent carbon nanostructure. This new understanding suggests that tuning the nanoparticle-substrate interaction would provide unique ways of controlling the nanotube synthesis.

AB We report the initial results of a recent bilateral comparison of linewidth or critical dimension (CD) calibrations on photomask line features between two national metrology institutes (NMIs): the National Institute of Standards and Technology (NIST) in the United States and the Physikalisch-Technische Bundesanstalt (PTB) in Germany. For the comparison, a chrome on glass (CoG) photomask was used which has a layout of line features down to 100 nm nominal size. Different measurement methods were used at both institutes. These included: critical dimension atomic force microscopy (CD-AFM), CD scanning electron microscopy (CD-SEM) and ultraviolet (UV) transmission optical microscopy. The measurands are CD at 50 % height of the features as well as sidewall angle and line width roughness (LWR) of the features. On the isolated opaque features, we found agreement of the CD measurements at the 3 nm to 5 nm level on most features - usually within the combined expanded uncertainties of the measurements.

AB Critical dimension atomic force microscopes (CD-AFMs) use flared tips and two-dimensional sensing and control of the tip-sample interaction to enable scanning of features with near-vertical or even reentrant sidewalls. Sidewall sensing in CD-AFM usually involves lateral dither of the tip, which was the case in the first two generations of instruments. Current, third generation instruments also utilize a control algorithm and fast response piezo actuator to position the tip in a manner that resembles touch-triggering of coordinate measuring machine (CMM) probes. All methods of tip position control, however, induce an effective tip width that may deviate from the actual geometrical tip width.
The National Institute of Standards and Technology (NIST) has been investigating the dependence of effective tip width on the dither settings and lateral stiffness of the tip, as well as the possibility of material effects due to sample composition. We have concluded that these effects will not generally result in a residual bias, provided that the tip calibration and sample measurement are performed under the same conditions.
To further validate our prior conclusions about the dependence of effective tip width on lateral stiffness, we recently performed experiments using a very large non-CD tip with an etched plateau of approximately 2 mu m width. The effective lateral stiffness of these tips is at least 20 times greater than typical CD-AFM tips, and these results supported our prior conclusions about the expected behavior for larger tips. The bottom-line importance of these latest observations is that we can now reasonably conclude that a dither slope of 3 nm/V is the baseline response due to the induced motion of the cantilever base.

AB X-ray spectra suffer significantly degraded spatial resolution when measured in the variable-pressure scanning electron microscope (VPSEM, chamber pressure 1 Pa to 2500 Pa) as compared to high-vacuum SEM (operating pressure < 10 mPa). Depending on the gas path length, electrons that are scattered hundreds of micrometers outside the focused beam can contribute 90% or more of the measured spectrum. Monte Carlo electron trajectory simulation, available in NIST DTSA-II, models the gas scattering and simulates mixed composition targets, e.g., particle on substrate. The impact of gas scattering at the major (C > 0.1 mass fraction), minor (0.01 <= C <= 0.1), and trace (C < 0.01) constituent levels can be estimated.

AB This is the fourth part of a series of tutorial papers discussing various causes of measurement uncertainty in scanned particle beam instruments, and some of the solutions researched and developed at NIST and other research institutions. Scanned particle beam instruments, especially the scanning electron microscope (SEM), have gone through tremendous evolution to become indispensable tools for many and diverse scientific and industrial applications. These improvements have significantly enhanced their performance and made them far easier to operate. But, the ease of operation has also fostered operator complacency. In addition, the user-friendliness has reduced the apparent need for extensive operator training. Unfortunately, this has led to the idea that the SEM is just another expensive "digital camera" or another peripheral device connected to a computer and that all of the problems in obtaining good quality images and data have been solved. Hence, one using these instruments may be lulled into thinking that all of the potential pitfalls have been fully eliminated and believing that, everything one sees on the micrograph is always correct. But, as described in this and the earlier papers, this may not be the case. Care must always be taken when reliable quantitative data are being sought. The first paper in this series discussed some of the issues related to signal generation in the SEM, including instrument calibration, electron beam-sample interactions and the need for physics-based modeling to understand the actual image formation mechanisms to properly interpret SEM images. The second paper has discussed another major issue confronting the microscopist: specimen contamination and methods to eliminate it. The third paper discussed mechanical vibration and stage drift and some useful solutions to mitigate the problems caused by them, and here, in this the fourth contribution, the issues related to specimen "charging" and its mitigation are discussed relative to dimensional metrology.

AB Gas- and aerosol-phase measurements of oxidants, biogenic volatile organic compounds (BVOCs) and organic nitrates made during the Southern Oxidant and Aerosol Study (SOAS campaign, Summer 2013) in central Alabama show that a nitrate radical (NO3) reaction with monoterpenes leads to significant secondary aerosol formation. Cumulative losses of NO3 to terpenes are correlated with increase in gas- and aerosol- organic nitrate concentrations made during the campaign. Correlation of NO3 radical consumption to organic nitrate aerosol formation as measured by aerosol mass spectrometry and thermal dissociation laser-induced fluorescence suggests a molar yield of aerosol-phase monoterpene nitrates of 23-44 %. Compounds observed via chemical ionization mass spectrometry (CIMS) are correlated to predicted nitrate loss to BVOCs and show C10H17NO5, likely a hydroperoxy nitrate, is a major nitrate-oxidized terpene product being incorporated into aerosols. The comparable isoprene product C5H9NO5 was observed to contribute less than 1% of the total organic nitrate in the aerosol phase and correlations show that it is principally a gas-phase product from nitrate oxidation of isoprene. Organic nitrates comprise between 30 and 45% of the NOy budget during SOAS. Inorganic nitrates were also monitored and showed that during incidents of increased coarse-mode mineral dust, HNO3 uptake produced nitrate aerosol mass loading at a rate comparable to that of organic nitrate produced via NO3 + BVOCs.

AB Visible Multifilter Rotating Shadowband Radiometer (vis-MFRSR) data were collected at Storm Peak Laboratory (SPL), a mountain-top facility in northwest Colorado, from 1999 to 2011 and in 2013. From 2011 to 2014, in situ measurements of aerosol light scattering were also obtained. Using these data sets together, the seasonal impact of dust and biomass burning is considered for the western USA. Analysis indicates that the median contributions to spring and summer aerosol optical depth (AOD) from dust and biomass-burning aerosols across the data set are comparable. The mean AOD is slightly greater in the summer, with significantly more frequent and short-duration high AOD measurements due to biomass-burning episodes than in the spring. The angstrom ngstrom exponent showed a significant increase in the summer for both the in situ and vis-MFRSR data, suggesting an increase in combustion aerosols. Spring dust events are less distinguishable in the in situ data than the column measurement, suggesting that a significant amount of dust may be found above the elevation of SPL, 3220 ma.s.l. Twenty-two known case studies of intercontinental dust, regional dust, and biomass-burning events were investigated. These events were found to follow a similar pattern, in both aerosol loading and angstrom ngstrom exponent, as the seasonal mean signal in both the vis-MFRSR and ground-based nephelometer. This data set highlights the wide-scale implications of a warmer, drier climate on visibility in the western USA.

AB Atmospheric variations of carbon dioxide (CO2) mole fraction reflect changes in atmospheric transport and regional patterns of surface emission and uptake. Here we present a study of changes in the observed high northern latitude CO2 seasonal cycle. We report new estimates for changes in the phase and amplitude of the seasonal variations, indicative of biospheric changes, by spectrally decomposing multi-decadal records of surface CO2 mole fraction using a wavelet transform to isolate the changes in the observed seasonal cycle. We also perform similar analysis of the first derivative of CO2 mole fraction, Delta tCO2, that is a crude proxy for changes in CO2 flux. Using numerical experiments, we quantify the aliasing error associated with independently identifying trends in phase and peak uptake and release to be 10-25 %, with the smallest biases in phase associated with the analysis of Delta tCO(2). We report our analysis from Barrow, Alaska (BRW), during 1973-2013, which is representative of the broader Arctic region. We determine an amplitude trend of 0.09 +/- 0.02 ppmy r(-1), which is consistent with previous work. Using Delta tCO2 we determine estimates for the timing of the onset of net uptake and release of CO2 of 0.14 +/- 0.14 and 0.25 +/- 0.08 days yr(-1) respectively and a corresponding net uptake period of 0.11 +/- 0.16 days yr(-1), which are significantly different to previously reported estimates. We find that the wavelet transform method has significant skill in characterizing changes in the peak uptake and release. We find a trend of 0.65 +/- 0.34% yr(-1) (p < 0.01) and 0.42 +/- 0.34 % yr(-1) (p < 0.05) for rates of peak uptake and release respectively. Our analysis does not provide direct evidence about the balance between uptake and release of carbon when integrated throughout the year, but the increase in the seasonal amplitude of CO2 together with an invariant net carbon uptake period provides evidence that high northern latitude ecosystems are progressively taking up more carbon during spring and early summer.

TI Role of radiatively forced temperature changes in enhanced semi-arid
warming in the cold season over east Asia
SO ATMOSPHERIC CHEMISTRY AND PHYSICS

BLOCKING; PACIFIC; IMPACTS
AB As climate change has occurred over east Asia since the 1950s, intense interest and debate have arisen concerning the contribution of human activities to the observed warming in past decades. In this study, we investigate regional surface temperature change during the boreal cold season using a recently developed methodology that can successfully identify and separate the dynamically induced temperature (DIT) and radiatively forced temperature (RFT) changes in raw surface air temperature (SAT) data. For regional averages, DIT and RFT contribute 44 and 56% to the SAT over east Asia, respectively. The DIT changes dominate the SAT decadal variability and are mainly determined by internal climate variability, represented by the North Atlantic Oscillation (NAO), Pacific Decadal Oscillation (PDO), and Atlantic Multi-decadal Oscillation (AMO). Radiatively forced SAT changes have made a major contribution to the global-scale warming trend and the regional-scale enhanced semi-arid warming (ESAW). Such enhanced warming is also found in radiatively forced daily maximum and minimum SAT. The long-term global-mean SAT warming trend is mainly related to radiative forcing produced by global well-mixed greenhouse gases. The regional anthropogenic radiative forcing, however, caused the enhanced warming in the semi-arid region, which may be closely associated with local human activities. Finally, the relationship between the so-called "global warming hiatus" and regional enhanced warming is discussed.

ID PRODUCT DEVELOPMENT
AB The PSI spaces are a framework for studying designing as practiced in the real world: framing and solving technical, social or organizational goals embedded in the existing socio-economic and institutional cultures and practices. Given the interconnected nature of the design product, knowledge and activities, we should anticipate that understanding designing is at least as complex as designing itself. Consequently, understanding designing involves mobilizing multiple knowledge sources, with different perspectives and diversity of participants orchestrated to achieve an effective outcome. We call the study of the PSI spaces the PSI framework. We introduce the PSI spaces, and their language resting on diverse disciplines such as psychology, engineering, economics, and sociology. We introduce some of its methodological tools; how the PSI spaces might be used to explain design challenges through misalignments of the spaces and how these misalignments could be resolved. The PSI framework has significant implication to the development of design science; it demands that design science be a trans-disciplinary endeavor, in need of a flexible community that will study it.

AB Alzheimer's disease has been shown to have a global reduction in gene expression, called an epigenetic blockade, which may be regulated by histone post-translational modifications. Histone H3 has been shown to be highly regulated by phosphorylation. We, therefore, chose H3 for investigation of phosphorylation of the core sites serine-57 (S57) and threonine-58 (T58). Hemispheres of brains from a mouse model of rapid amyloid deposition (5XFAD) were used for measurement of S57 and T58 phosphorylation. Multiple reaction monitoring (MRM) was used to measure the level of phosphorylation, which was normalized to a non-modified "housekeeping" peptide of H3. S57 phosphorylation was decreased by 40%, T58 phosphorylation was decreased by 45%, and doubly phosphorylated S57pT58p was decreased by 30% in 5XFAD brain in comparison to C57BL/6J age-and sex-matched wild type controls. Amyloid-beta (A beta) and amyloid precursor protein were also measured to confirm that 5XFAD mice produced high levels of Ab. Decreased phosphorylation of these sites in close proximity to DNA may lead to stabilization of DNA-histone interactions and a condensed chromatin state, consistent with the epigenetic blockade associated with AD. Our findings of H3 sites S57 and T58 exhibiting lower levels of phosphorylation in 5XFAD model compared to wild type control implicate these sites in the epigenetic blockade in neurodegeneration pathology.

AB A sequence pi = (d(1),..., d(n)) is graphic if there is a simple graph G with vertex set {v(1),..., v(n)} such that the degree of v(i) is d(i). We say that graphic sequences pi(1) = (d(1)((1)),..., d(n)((1))) and pi(2) = (d(1)((2)),..., d(n)((2))) pack if there exist edge-disjoint n-vertex graphs G(1) and G(2) such that for j is an element of {1, 2}, d(Gj) (v(i)) = d(i)((j))i for all i is an element of {1,..., n}. Here, we prove several extremal degree sequence packing theorems that parallel central results and open problems from the graph packing literature. Specifically, the main result of this paper implies degree sequence packing analogues to the Bollobas Eldridge- Catlin graph packing conjecture and the classical graph packing theorem of Sauer and Spencer. In discrete tomography, a branch of discrete imaging science, the goal is to reconstruct discrete objects using data acquired from low-dimensional projections. Specifically, in the k-color discrete tomography problem the goal is to color the entries of an m x n matrix using k colors so that each row and column receives a prescribed number of entries of each color. This problem is equivalent to packing the degree sequences of k bipartite graphs with parts of sizes m and n. Here we also prove several Sauer-Spencer-type theorems with applications to the two-color discrete tomography problem.

AB Identification of sharks within the genus Mustelus (smoothhound sharks) is problematic because of extensive overlap in external morphology among species. Consequently, species-specific management of smoothhound shark resources is difficult when multiple species inhabit the same geographic region. The species identification and distribution of smoothhound sharks in the northern Gulf of Mexico (the Gulf) were assessed using sequences of mitochondrial DNA, nuclear-encoded microsatellites, and catch data. Phylogenetic analysis of 1,047 base pairs of mitochondrially encoded ND-2 sequences and Bayesian clustering of multilocus genotypes at 15 microsatellites revealed three genetically distinct monophyletic lineages (clades) of smoothhound sharks in the Gulf. Examination of external morphology revealed characters that distinguished each genetically distinct clade, and based on species descriptions and comparisons with the type and other specimens in established collections, the lineages were identified as Smooth Dogfish Mustelus canis, Florida Smoothhound Mustelus norrisi, and Gulf Smoothhound Mustelus sinusmexicanus. Two hundred and eighty-seven smoothhound sharks sampled from across the Gulf were then assigned unequivocally, based on genetic data, to one of the three species. Multifactorial analysis and homogeneity tests of species-specific means versus grand means of spatiotemporal factors (depth, longitude, and month) at capture indicated significant differences among the three species with respect to all three factors. On average, the Smooth Dogfish is found in deeper waters than the Gulf Smoothhound, whereas the Florida Smoothhound inhabits relatively shallow waters. A diagnostic key for the field identification of adult specimens of each species is provided.

AB Retrospective decadal forecasts were undertaken using the Climate Forecast System version 2 (CFSv2) as part of Coupled Model Intercomparison Project 5. Decadal forecasts were performed separately by the National Center for Environmental Prediction (NCEP) and by the Center for Ocean-Land-Atmosphere Studies (COLA), with the centers using two different analyses for the ocean initial conditions the NCEP Climate Forecast System Reanalysis (CFSR) and the NEMOVAR-COMBINE analysis. COLA also examined the sensitivity to the inclusion of forcing by specified volcanic aerosols. Biases in the CFSv2 for both sets of initial conditions include cold midlatitude sea surface temperatures, and rapid melting of sea ice associated with warm polar oceans. Forecasts from the NEMOVAR-COMBINE analysis showed strong weakening of the Atlantic Meridional Overturning Circulation (AMOC), eventually approaching the weaker AMOC associated with CFSR. The decadal forecasts showed high predictive skill over the Indian, the western Pacific, and the Atlantic Oceans and low skill over the central and eastern Pacific. The volcanic forcing shows only small regional differences in predictability of surface temperature at 2m (T2m) in comparison to forecasts without volcanic forcing, especially over the Indian Ocean. An ocean heat content (OHC) budget analysis showed that the OHC has substantial memory, indicating potential for the decadal predictability of T2m; however, the model has a systematic drift in global mean OHC. The results suggest that the reduction of model biases may be the most productive path towards improving the model's decadal forecasts.

AB There are potential advantages to extending operational seasonal forecast models to predict decadal variability but major efforts are required to assess the model fidelity for this task. In this study, we examine the North Atlantic climate simulated by the NCEP Climate Forecast System, version 2 (CFSv2), using a set of ensemble decadal hindcasts and several 30-year simulations initialized from realistic ocean- atmosphere states. It is found that a substantial climate drift occurs in the first few years of the CFSv2 hindcasts, which represents a major systematic bias and may seriously affect the model's fidelity for decadal prediction. In particular, it is noted that a major reduction of the upper ocean salinity in the northern North Atlantic weakens the Atlantic meridional overturning circulation (AMOC) significantly. This freshening is likely caused by the excessive freshwater transport from the Arctic Ocean and weakened subtropical water transport by the North Atlantic Current. A potential source of the excessive freshwater is the quick melting of sea ice, which also causes unrealistically thin ice cover in the Arctic Ocean. Our sensitivity experiments with adjusted sea ice albedo parameters produce a sustainable ice cover with realistic thickness distribution. It also leads to a moderate increase of the AMOC strength. This study suggests that a realistic freshwater balance, including a proper sea ice feedback, is crucial for simulating the North Atlantic climate and its variability.

DE Suomi NPP VIIRS DNB; Response vs. scan angle; Night light stability
AB The low gain stage of VIIRS Day/Night Band (DNB) on Suomi-NPP is calibrated using onboard solar diffuser. The calibration is then transferred to the high gain stage of DNB based on the gain ratio determined from data collected along solar terminator region. The calibration transfer causes increase of uncertainties and affects the accuracy of the low light radiances observed by DNB at night. Since there are 32 aggregation zones from nadir to the edge of the scan and each zone has its own calibration, the calibration versus scan angle of DNB needs to be independently assessed. This study presents preliminary analysis of the scan-angle dependence of the light intensity from bridge lights, oil platforms, power plants, and flares observed by VIIRS DNB since 2014. Effects of atmospheric path length associated with scan angle are analyzed. In addition, other effects such as light changes at the time of observation are also discussed. The methodology developed will be especially useful for JPSS J1 VIIRS due to the nonlinearity effects at high scan angles, and the modification of geolocation software code for different aggregation modes. It is known that J1 VIIRS DNB has large nonlinearity across aggregation zones, and requires new aggregation modes, as well as more comprehensive validation.

DE Suomi NPP VIIRS DNB; Night light stability; Ground based light sources
AB There is a growing interest in the science and user community in the Visible Infrared Imaging Radiometer Suite (VIIRS) Day/Night Band (DNB) low light detection capabilities at night for quantitative applications such as airglow, geophysical retrievals under lunar illumination, light power estimation, search and rescue, energy use, urban expansion and other human activities. Given the growing interest in the use of the DNB data, a pressing need arises for improving the calibration stability and absolute accuracy of the DNB at low radiances. Currently the low light calibration accuracy was estimated at a moderate 15%-100% while the long-term stability has yet to be characterized. This study investigates selected existing night light point sources from Suomi NPP DNB observations and evaluates the feasibility of SI traceable nightlight source at radiance levels near 3 nW.cm(-2).sr(-1), that potentially can be installed at selected sites for VIIRS DNB calibration/validation. The illumination geometry, surrounding environment, as well as atmospheric effects are also discussed. The uncertainties of the ground based light source are estimated. This study will contribute to the understanding of how the Earth's atmosphere and surface variability contribute to the stability of the DNB measured radiances, and how to separate them from instrument calibration stability. It presents the need for SI traceable active light sources to monitor the calibration stability, radiometric and geolocation accuracy, and point spread functions of the DNB. Finally, it is also hoped to address whether or not active light sources can be used for detecting environmental changes, such as aerosols.

AB The Soumi-NPP Visible Infrared Imaging Radiometer Suite (VIIRS) was launched on October 28th, 2011 and its Sensor Data Record (SDR) product reached maturity status in March of 2014. Although the VIIRS SDR products are declared at the validated maturity level, there remain issues such as residual stripings in some thermal bands along with the scan direction. These horizontal striping issues in the Thermal Emissive Bands (TEB) were reflected in the sea surface temperature (SST) products. The observed striping magnitude can reach to 0.2 K, especially at the band M14 and M15.
As an independent source of calibration, the Solar Diffuser (SD) is utilized in this study. The SD is originally designed for the Reflective Solar Band (RSB), however, it is assumed to be thermally stable at the time of SD observation. For each detector, a linear slope is developed by Integrated Calibration and Validation System (ICVS), which is applied on converting digital number (DN) to radiance unit. After the conversion, detector based noise analyses in VIIRS band M15 and M16 are performed on in-scan and scan-by-scan SD responses. Since SD radiance varies within an orbit, the noise calculation must be derived from the neighborhood Allan deviation. The noise derived Allan deviation shows that detector 1 and 2 in band M15 and detector 9 in band M16 have higher noise content compared to other detectors.

AB The accuracy of pre-launch VIIRS response versus scan angle (RVS) characterization is vitally important to the quality of calibrated radiance products. The RVS correct the optical system's scan angle dependency with respect to the calibrator scan angle. In this document, we describe the methodology used in JPSS-1 RSB RVS characterization and the efficacy of MODTRAN5 in water vapor correction. The RVS is characterized using a 2nd order polynomial fit over the measured scan angles. The results show high fitting accuracy for all bands except for M9 due to water vapor absorption. To improve M9 RVS, MODTRAN(R)5 is used to correction water vapor absorption variation during the RVS measurements. This correction greatly reduced M9 RVS characterization uncertainty with a RVS that is up to 0.4% difference compared with RVS prior to water vapor correction.

AB During JPSS-1 VIIRS testing at Raytheon El Segundo, a larger than expected radiometric response nonlinearity was discovered in Day-Nigh Band (DNB). In addition, the DNB nonlinearity is aggregation mode dependent, where the most severe non-linear behavior are the aggregation modes used at high scan angles (>similar to 50 degree). The DNB aggregation strategy was subsequently modified to remove modes with the most significant non-linearity. We characterized the DNB radiometric response using pre-launch tests with the modified aggregation strategy. The test data show the DNB non-linearity varies at each gain stages, detectors and aggregation modes. The non-linearity is most significant in the Low Gain Stage (LGS) and could vary from sample-to-sample. The non-linearity is also more significant in EV than in calibration view samples. The HGS nonlinearity is difficult to quantify due to the higher uncertainty in determining source radiance. Since the radiometric response non-linearity is most significant at low dn ranges, it presents challenge in DNB cross-stage calibration, an critical path to calibration DNB's High Gain Stage (HGS) for nighttime imagery. Based on the radiometric characterization, we estimated the DNB on-orbit calibration accuracy and compared the expected DNB calibration accuracy using operational calibration approaches. The analysis showed the non-linearity will result in cross-stage gain ratio bias, and have the most significant impact on HGS. The HGS calibration accuracy can be improved when either SD data or only the more linearly behaved EV pixels are used in cross-stage calibration. Due to constrain in test data, we were not able to achieve a satisfactory accuracy and uniformity for the JPSS-1 DNB nighttime imagery quality. The JPSS-1 DNB nonlinearity is a challenging calibration issue which will likely require special attention after JPSS-1 launch.

AB Terra (T) MODerate-resolution Imaging Spectroradiometer (MODIS), a heritage Earth observing sensor has completed 15 years of operation as of December 18 2014. T-MODIS has 36 spectral channels designed to monitor the land, ocean, and atmosphere. The long term climate data record from T-MODIS is an important dataset for global change monitoring. Sixteen of the spectral channels fall in the Mid (M) (3.7-4.5 mu m) to Long (L) (6.7-14.1 mu m) Wave InfraRed (M/LWIR) wavelengths, which are also referred to as the Thermal Emissive Bands (TEBs). To date the TEBs have very satisfactory performance which is attributed to the scan-by-scan calibration using an on-board BlackBody whose temperature is traceable to the NIST temperature standards. However, with an aging instrument, it was observed from 2010 onwards that the Photo Voltaic LWIR channels (Bands 27-30) have suffered significantly from electronic crosstalk. This is mainly due to the deterioration of the electronic circuits of the relevant bands in the LWIR Focal Plane Array (FPA). In this paper, we report the characterization of the electronic crosstalk in the above-mentioned bands using the well characterized test site such as Dome Concordia (C). Such characterization can be used to reduce the effects of crosstalk when implemented in the future Level 1B reprocessing and thereby increasing the radiometric fidelity of the concerned bands.

AB The Day/Night Band (DNB) of the Visible Infrared Imaging Radiometer Suite (VIIRS) onboard Suomi National Polar-orbiting Partnership (Suomi-NPP) represents a major advancement in night time imaging capabilities. The VIIRS DNB sensor is affected by stray light. Straylight effect on the DNB instrument is due to solar illumination entering the optical path after the satellite passes through the day-night terminator projected on Earth's surface. It results in an overall increase in the recorded radiance values. This effect is more significant during solstice. After the launch of Suomi-NPP in October 2011, there was a gray haze in radiance images observed by DNB due to straylight, and straylight correction has been implemented to remove this effect. This study performs vicarious validation of straylight correction for VIIRS DNB band using Dome C in Antarctic. Nadir observations of these high latitude regions by VIIRS are selected during perpetual night season, i.e. from April to July during the year 2014 under various lunar phases. The dependence of observed radiance over Dome C on lunar phases and the cross-comparison between DNB observations for events with/without straylight are shown in this paper. This paper presents an effective method to assess the performance of straylight correction for VIIRS DNB in Southern Hemisphere.

AB The MODerate-resolution Imaging Spectroradiometer (MODIS) is a legacy Earth remote sensing instrument in the National Aeronautics and Space Administration (NASA) Earth Observing System (EOS). The first MODIS instrument was launched in December 1999 on board the Terra spacecraft. MODIS has 36 bands, among which bands 20-25 and bands 27-36 are thermal emissive bands covering a wavelength range from 3.7. m to 14.2. m. It has been found that there are severe contaminations in Terra bands 27-30 (6.7 mu m -9.73 mu m) due to crosstalk of signals among themselves. The crosstalk effect induces strong striping artifacts in the Earth View (EV) images and causes large long-term drifts in the EV brightness temperature (BT) in these bands. An algorithm using a linear approximation derived from on-orbit lunar observations has been developed to correct the crosstalk effect for them. It was demonstrated that the crosstalk correction can substantially reduce the striping noise in the EV images and significantly remove the long-term drifts in the EV BT in the Long Wave InfraRed (LWIR) water vapor channels (bands 27-28). In this paper, the crosstalk correction algorithm previously developed is applied to correct the crosstalk effect in the remaining LWIR bands 29 and 30. The crosstalk correction successfully reduces the striping artifact in the EV images and removes long-term drifts in the EV BT in bands 29-30 as was done similarly for bands 27-28. The crosstalk correction algorithm can thus substantially improve both the image quality and the radiometric accuracy of the Level 1B (L1B) products of the LWIR PV bands, bands 27-30. From this study it is also understood that other Terra MODIS thermal emissive bands are contaminated by the crosstalk effect and that the algorithm can be applied to these bands for crosstalk correction.

AB Suomi NPP VIIRS SWIR band M11 (2.25 mu m) has larger radiometric uncertainty compared to the rest of the reflective solar bands. This is due to a number of reasons including prelaunch calibration uncertainties. One of the most commonly used technique to verify the radiometric stability and accuracy of VIIRS is by intercomparing it with other well calibrated radiometers such as MODIS. However one of the limitations of using MODIS is that VIIRS band M11 RSR doesn't overlap with MODIS bands at all. Thus the accuracy of intercomparison relies completely on how well the spectral differences are analyzed over the given target. Since desert sites have higher reflectance and more flat spectra, this study uses desert sites to analyze M11 radiometric performance. In order to better match the RSR between instruments, we have chosen Landsat 8 OLI SWIR band 2 (2.20 mu m) to perform intercomparison. This is mainly because OLI SWIR band 2 fully covers the VIIRS band M11 even though OLI has much wider RSR compared to VIIRS. The study suggests that there exists large radiometric inconsistency between VIIRS M11 and OLI, on the order of 5%. The impact due to spectral differences is estimated and accounted for using EO-1 Hyperion observations and MODTRAN.

AB The polarization sensitivity of the Visible/NearIR (VISNIR) bands in the Joint Polar Satellite Sensor 1 (J1) Visible Infrared Imaging Radiometer Suite (VIIRS) instrument was measured using a broadband source. While polarization sensitivity for bands M5-M7, I1, and I2 was less than 2.5 %, the maximum polarization sensitivity for bands M1, M2, M3, and M4 was measured to be 6.4 %, 4.4 %, 3.1 %, and 4.3 %, respectively with a polarization characterization uncertainty of less than 0.38%. A detailed polarization model indicated that the large polarization sensitivity observed in the M1 to M4 bands is mainly due to the large polarization sensitivity introduced at the leading and trailing edges of the newly manufactured VISNIR bandpass focal plane filters installed in front of the VISNIR detectors. This was confirmed by polarization measurements of bands M1 and M4 bands using monochromatic light. Discussed are the activities leading up to and including the two polarization tests, some discussion of the polarization model and the model results, the role of the focal plane filters, the polarization testing of the Aft-Optics-Assembly, the testing of the polarizers at the National Aeronautics and Space Administration's (NASA) Goddard center and at the National Institute of Science and Technology (NIST) facility and the use of NIST's Traveling Spectral Irradiance and Radiance responsivity Calibrations using Uniform Sources (T-SIRCUS) for polarization testing and associated analyses and results.

AB Morphological changes resulting from the oxidation of zero valent iron (ZVI) nanoparticles were measured as an assessment of their mechanical robustness in mixed matrix membranes for water treatment applications. Upon oxidation from metallic iron to iron oxide hydroxide, FeO(OH), particles underwent a significant transformation in size and morphology from 100 nm diameter spherical particles to plate-like crystalline particles with a hydrodynamic diameter greater than 450 nm. Atomic force microscopy (AFM) was used to mechanically degrade the FeO(OH) crystallites during repeated imaging. To determine whether similar degradation would occur during water filtration in a mixed matrix membrane, force under standard membrane operating conditions was calculated. Such force calculations were used to compare the shear forces exerted during water flux in a mixed matrix membrane to the normal forces imparted by AFM. Analysis suggested that the oxidized ZVI nanoparticles will experience a 10(-19) N maximum shear force in pore channels, much lower than the imaging forces in AFM, suggesting the mechanical stability of the particles during water remediation. Additional quartz crystal microbalance experiments were performed to confirm the mechanical stability of the oxidized iron nanoparticles in the flow environments of ultrafiltration. Taken together, the results of this study demonstrate that the mechanical properties of the nanoparticle composite membranes are such that minimal mechanical degradation of the nanoparticles will occur during water filtration.

AB Nanocarbon materials, including sp(2) hybridized two-dimensional graphene and one-dimensional carbon nanotubes, and sp(1) hybridized one-dimensional carbyne, are being considered for the next generation of integrated optoelectronic devices. The strong electron-phonon coupling present in these nanocarbon materials makes Raman spectroscopy an ideal tool to study and characterize the material and device properties. Near-field Raman spectroscopy combines non-destructive chemical, electrical, and structural specificity with nanoscale spatial resolution, making it an ideal tool for studying nanocarbon systems. Here we use near-field Raman spectroscopy to study strain, defects, and doping in different nanocarbon systems.

AB Thermal neutron detection is of vital importance to many disciplines, including neutron scattering, workplace monitoring, and homeland protection. We survey recent results from our collaboration which couple low-pressure noble gas scintillation with novel approaches to neutron absorbing materials and geometries to achieve potentially advantageous detector concepts. Noble gas scintillators were used for neutron detection as early as the late 1950's. Modern use of noble gas scintillation includes liquid and solid forms of argon and xenon in the dark matter and neutron physics experiments and commercially available high pressure applications have achieved high resolution gamma ray spectroscopy. Little attention has been paid to the overlap between low pressure noble gas scintillation and thermal neutron detection, for which there are many potential benefits.

AB A case study concerning validation of wind speed measurements made by a laser wind sensor mounted on a 190 square foot floating platform in Muskegon Lake through comparison with measurements made by pre-existing cup anemometers mounted on a met tower on the shore line is presented. The comparison strategy is to examine the difference in measurements over time using the paired-t statistical method to identify intervals when the measurements were equivalent and to provide explanatory information for the intervals when the measurements were not equivalent. The data was partitioned into three sets: not windy (average wind speed measured by the cup anemometers = 6.7m/s) windy but no enhanced turbulence (average wind speed measured by the cup anemometers > 6.7m/s), and windy with enhanced turbulence associated with storm periods. For the not windy data set, the difference in the average wind speeds was equal in absolute value to the precision of the gages and not statistically significant. Similar results were obtained for the windy with no enhanced turbulence data set and the average difference was not statistically significant (alpha=0.01). The windy with enhanced turbulence data set showed significant differences between the buoy mounted laser wind sensor and the on-shore mast mounted cup anemometers. The sign of the average difference depended on the direction of the winds. Overall, validation evidence is obtained in the absence of enhanced turbulence were isolated in time, studied and explained.

AB We demonstrate the simultaneous measurement of optical trap stiffness and quadrant-cell photodetector (QPD) calibration of optically trapped polystyrene particle in air. The analysis is based on the transient response of particles, confined to an optical trap, subject to a pulsed electrostatic field generated by parallel indium tin oxide (ITO) coated substrates. The resonant natural frequency and damping were directly estimated by fitting the analytical solution of the transient response of an underdamped harmonic oscillator to the measured particle displacement from its equilibrium position. Because, the particle size was estimated independently with video microscopy, this approach allowed us to measure the optical force without ignoring the effects of inertia and temperature changes from absorption.

AB Gold nanoparticles (GNP) have wide applications ranging from nanoscale heating to cancer therapy and biological sensing. Optical trapping of GNPs as small as 18 nm has been successfully achieved with laser power as high as 855 mW, but such high powers can damage trapped particles (particularly biological systems) as well heat the fluid, thereby destabilizing the trap.
In this article, we show that counter propagating beams (CPB) can successfully trap GNP with laser powers reduced by a factor of 50 compared to that with a single beam. The trapping position of a GNP inside a counter-propagating trap can be easily modulated by either changing the relative power or position of the two beams. Furthermore, we find that under our conditions while a single-beam most stably traps a single particle, the counter-propagating beam can more easily trap multiple particles. This (CPB) trap is compatible with the feedback control system we recently demonstrated to increase the trapping lifetimes of nanoparticles by more than an order of magnitude. Thus, we believe that the future development of advanced trapping techniques combining counter-propagating traps together with control systems should significantly extend the capabilities of optical manipulation of nanoparticles for prototyping and testing 3D nanodevices and bio-sensing.

AB In contrast to the National Oceanic and Atmospheric Administration's (NOAA's) current geostationary imagers for operational weather forecasting, the next generation imager, the Advanced Baseline Imager (ABI) aboard the Geostationary Operational Environmental Satellite R-Series (GOES-R), will have six reflective solar bands - five more than currently available. These bands will be used for applications such as aerosol retrievals, which are influenced by polarization effects. These effects are determined by two factors: instrument polarization sensitivity and the polarization states of the observations. The former is measured as part of the pre-launch testing program performed by the instrument vendor. We analyzed the results of the pre-launch polarization sensitivity measurements of the 0.47 mu m and 0.64 mu m channels and used them in conjunction with simulated scene polarization states to estimate potential on-orbit radiometric impacts. The pre-launch test setups involved illuminating the ABI with an integrating sphere through either one or two polarizers. The measurement with one (rotating) polarizer yields the degree of linear polarization of ABI, and the measurements using two polarizers (one rotating and one fixed) characterized the non-ideal properties of the polarizer. To estimate the radiometric performance impacts from the instrument polarization sensitivity, we simulated polarized scenes using a radiative transfer code and accounted for the instrument polarization sensitivity over its field of regard. The results show the variation in the polarization impacts over the day and by regions of the full disk can reach up to 3.2% for the 0.47 mu m channel and 4.8% for the 0.64 mu m channel. Geostationary orbiters like the ABI give the unique opportunity to show these impacts throughout the day compared to low earth orbiters, which are more limited to certain times of day. This work may enhance the ability to diagnose anomalies on-orbit.

AB Spontaneous parametric down-conversion (SPDC) is a common method to generate entangled photon pairs for use in quantum communications. The generated single photon linewidth is a critical issue for photon-atom interactions in quantum memory applications. We compare the linewidths of greatly non-degenerate single photon pairs from SPDC generated in the single-pass case and the singly-resonant cavity case. For a 6 mm periodically poled lithium niobate (PPLN) crystal, the linewidth of the generated signal photons is reduced from 1 THz in the single pass case to tens of MHz in the singly-resonant cavity case, while the brightness within the modal linewidth is increased by a factor of the cavity finesse, though the overall SPDC generation rate remains unchanged.

AB In the past decade acoustic radiation force (ARF) became a powerful tool in numerous biomedical applications. ARF from a focused ultrasound beam acts as a virtual "finger" for remote probing of internal anatomical structures and obtaining diagnostic information. This presentation deals with generation of shear waves by nonlinear focused beams. Albeit the ARF has intrinsically nonlinear origin, in most cases the primary ultrasonic wave was considered in the linear approximation. In this presentation, we consider the effects of nonlinearly distorted beams on generation of shear waves by such beams.

AB Rice production in Bangladesh is a crucial part of the national economy and providing about 70 percent of an average citizen's total calorie intake. The demand for rice is constantly rising as the new populations are added in every year in Bangladesh. Due to the increase in population, the cultivation land decreases. In addition, Bangladesh is faced with production constraints such as drought, flooding, salinity, lack of irrigation facilities and lack of modern technology. To maintain self sufficiency in rice, Bangladesh will have to continue to expand rice production by increasing yield at a rate that is at least equal to the population growth until the demand of rice has stabilized. Accurate rice yield prediction is one of the most important challenges in managing supply and demand of rice as well as decision making processes. Artificial Neural Network (ANN) is used to construct a model to predict Aus rice yield in Bangladesh. Advanced Very High Resolution Radiometer (AVHRR)-based remote sensing satellite data vegetation health (VH) indices (Vegetation Condition Index (VCI) and Temperature Condition Index (TCI)) are used as input variables and official statistics of Aus rice yield is used as target variable for ANN prediction model. The result obtained with ANN method is encouraging and the error of prediction is less than 10%. Therefore, prediction can play an important role in planning and storing of sufficient rice to face in any future uncertainty.

AB A preliminary investigation was conducted into the feasibility of using simple mechanical properties experiments to evaluate interstitial impurity uptake from processing environments. Two types of tests were examined: tensile tests and complex modulus measurements using a dynamic mechanical analyzer (DMA). For the tensile tests, samples were cut from a single crystal of niobium, with the same orientation, and then prepared following different procedures. Significant differences were observed during tensile tests, with yielding strength and strain-to-failure clearly related to interstitial uptake. When the strain rate was reduced by an order of magnitude, the strain-to-failure was reduced by 18 % indicating that interstitial hydrogen is responsible for this behavior. For the complex modulus measurement, polycrystalline samples from different locations of two different ingots were examined at a frequency of 1.0 Hz while the temperature was increased at the rate of 1.0 degrees C per minute. Anaelastic peaks were found for C, N, and O in all samples, but the lower limit of the system did not allow for detection of a peak for H. It is concluded that mechanical properties could be developed as a measurement tool to guide the development of processing methods for producing reduced interstitial content material, but additional research, and uncertainty analysis, is required for these tools to be reliable in this application.

AB An ultrashort XUV laser pulse ionizes the D-2 molecule creating an electronic and nuclear wave packet, with the dominant contributions from the 2s sigma(g) and 2p pi(u) ionic states. A delayed interaction with a 780 nm IR field ejects the second electron, leading to the Coulomb explosion of the molecule, whose nuclear fragments, recorded in coincidence, map the dynamics associated to those two ionic excited states. By varying the orientation of the light polarization, one can control the molecular dynamics by modifying the ratio between the ionic states. Experimental and ab initio theoretical data are jointly reported.

AB Photoassociation spectroscopy, based on forming of molecules from colliding atoms in the presence of light, is a priceless tool for the study of atomic interactions. It enables direct measurements of bound state energies, both in excited and ground state molecules. Applications include determinations of s-wave scattering lengths, as well as atomic state lifetimes. In this work we present the results of our research on the mass-scaling behaviour of molecular bound state energies and collisional properties in spin-singlet atoms. We will concentrate on two such species: strontium and ytterbium, both of which offer several stable isotopes, enabling mass tuning of the system's properties.

AB It is widely expected that global emissions of atmospheric aerosols and their precursors will decrease strongly throughout the remainder of the 21st century, due to emission reduction policies enacted to protect human health. For instance, global emissions of aerosols and their precursors are projected to decrease by as much as 80 % by the year 2100, according to the four Representative Concentration Pathway (RCP) scenarios. The removal of aerosols will cause unintended climate consequences, including an unmasking of global warming from long-lived greenhouse gases. We use the Geophysical Fluid Dynamics Laboratory Coupled Climate Model version 3 (GFDL CM3) to simulate future climate over the 21st century with and without the aerosol emission changes projected by each of the RCPs in order to isolate the radiative forcing and climate response resulting from the aerosol reductions. We find that the projected global radiative forcing and climate response due to aerosol decreases do not vary significantly across the four RCPs by 2100, although there is some mid-century variation, especially in cloud droplet effective radius, that closely follows the RCP emissions and energy consumption projections. Up to 1 W m(-2) of radiative forcing may be unmasked globally from 2005 to 2100 due to reductions in aerosol and precursor emissions, leading to average global temperature increases up to 1 K and global precipitation rate increases up to 0.09 mm day(-1). However, when using a version of CM3 with reduced present-day aerosol radiative forcing (-1.0 W m(-2)), the global temperature increase for RCP8.5 is about 0.5 K, with similar magnitude decreases in other climate response parameters as well. Regionally and locally, climate impacts can be much larger than the global mean, with a 2.1 K warming projected over China, Japan, and Korea due to the reduced aerosol emissions in RCP8.5, as well as nearly a 0.2 mm day(-1) precipitation increase, a 7 g m(-2) LWP decrease, and a 2 mu m increase in cloud droplet effective radius. Future aerosol decreases could be responsible for 30-40% of total climate warming (or 10-20% with weaker aerosol forcing) by 2100 in East Asia, even under the high greenhouse gas emissions scenario (RCP8.5). The expected unmasking of global warming caused by aerosol reductions will require more aggressive greenhouse gas mitigation policies than anticipated in order to meet desired climate targets.

AB Bidirectional air-surface exchange of ammonia (NH3) has been neglected in many air quality models. In this study, we implement the bidirectional exchange of NH3 in the GEOS-Chem global chemical transport model. We also introduce an updated diurnal variability scheme for NH3 livestock emissions and evaluate the recently developed MASAGE_NH3 bottom-up inventory. While updated diurnal variability improves comparison of modeled-to-hourly in situ measurements in the southeastern USA, NH3 concentrations decrease throughout the globe, up to 17 ppb in India and southeastern China, with corresponding decreases in aerosol nitrate by up to 7 mu g m(-3). The ammonium (NH4+) soil pool in the bidirectional exchange model largely extends the NH3 lifetime in the atmosphere. Including bidirectional exchange generally increases NH3 gross emissions (7.1 %) and surface concentrations (up to 3.9 ppb) throughout the globe in July, except in India and southeastern China. In April and October, it decreases NH3 gross emissions in the Northern Hemisphere (e.g., 43.6 % in April in China) and increases NH3 gross emissions in the Southern Hemisphere. Bidirectional exchange does not largely impact NH4+ wet deposition overall. While bidirectional exchange is fundamentally a better representation of NH3 emissions from fertilizers, emissions from primary sources are still underestimated and thus significant model biases remain when compared to in situ measurements in the USA. The adjoint of bidirectional exchange has also been developed for the GEOS-Chem model and is used to investigate the sensitivity of NH3 concentrations with respect to soil pH and fertilizer application rate. This study thus lays the groundwork for future inverse modeling studies to more directly constrain these physical processes rather than tuning bulk unidirectional NH3 emissions.

We quantitatively evaluate the XCO2 seasonal cycle of the Greenhouse Gases Observing Satellite (GOSAT) observations from the Atmospheric CO2 Observations from Space (ACOS) retrieval system and compare average regional seasonal cycle features to those directly measured by the Total Carbon Column Observing Network (TCCON). We analyse the mean seasonal cycle amplitude, dates of maximum and minimum XCO2, as well as the regional growth rates in XCO2 through the fitted trend over several years. We find that GOSAT/ACOS captures the seasonal cycle amplitude within 1.0 ppm accuracy compared to TCCON, except in Europe, where the difference exceeds 1.0 ppm at two sites, and the amplitude captured by GOSAT/ACOS is generally shallower compared to TCCON. This bias over Europe is not as large for the other GOSAT retrieval algorithms (NIES v02.21, RemoTeC v2.35, UoL v5.1, and NIES PPDF-S v.02.11), al-though they have significant biases at other sites. We find that the ACOS bias correction partially explains the shallow amplitude over Europe. The impact of the co-location method and aerosol changes in the ACOS algorithm were also tested and found to be few tenths of a ppm and mostly non-systematic. We find generally good agreement in the date of minimum XCO2 between ACOS and TCCON, but ACOS generally infers a date of maximum XCO2 2-3 weeks later than TCCON. We further analyse the latitudinal dependence of the seasonal cycle amplitude throughout the Northern Hemisphere and compare the dependence to that predicted by current optimized models that assimilate in situ measurements of CO2. In the zonal averages, models are consistent with the GOSAT amplitude to within 1.4 ppm, depending on the model and latitude. We also show that the seasonal cycle of XCO2 depends on longitude especially at the mid-latitudes: the amplitude of GOSAT XCO2 doubles from western USA to East Asia at 45-50 degrees N, which is only partially shown by the models. In general, we find that model-to-model differences can be larger than GOSAT-to-model differences. These results suggest that GOSAT/ACOS retrievals of the XCO2 seasonal cycle may be sufficiently accurate to evaluate land surface models in regions with significant discrepancies between the models.

TI Radiometric consistency assessment of hyperspectral infrared sounders
SO ATMOSPHERIC MEASUREMENT TECHNIQUES

AB The radiometric and spectral consistency among the Atmospheric Infrared Sounder (AIRS), the Infrared Atmospheric Sounding Interferometer (IASI), and the Cross-track Infrared Sounder (CrIS) is fundamental for the creation of long-term infrared (IR) hyperspectral radiance benchmark data sets for both intercalibration and climate-related studies. In this study, the CrIS radiance measurements on Suomi National Polar-orbiting Partnership (SNPP) satellite are directly compared with IASI on MetOp-A and MetOp-B at the finest spectral scale and with AIRS on Aqua in 25 selected spectral regions through simultaneous nadir overpass (SNO) observations in 2013, to evaluate radiometric consistency of these four hyperspectral IR sounders. The spectra from different sounders are paired together through strict spatial and temporal collocation. The uniform scenes are selected by examining the collocated Visible Infrared Imaging Radiometer Suite (VIIRS) pixels. Their brightness temperature (BT) differences are then calculated by converting the spectra onto common spectral grids. The results indicate that CrIS agrees well with IASI on MetOp-A and IASI on MetOp-B at the long-wave IR (LWIR) and middle-wave IR (MWIR) bands with 0.1-0.2K differences. There are no apparent scene-dependent patterns for BT differences between CrIS and IASI for individual spectral channels. CrIS and AIRS are compared at the 25 spectral regions for both polar and tropical SNOs. The combined global SNO data sets indicate that the CrIS-AIRS BT differences are less than or around 0.1K among 21 of 25 spectral regions and they range from 0.15 to 0.21K in the remaining four spectral regions. CrIS-AIRS BT differences in some comparison spectral regions show weak scene-dependent features.

TI HOx radical chemistry in oxidation flow reactors with low-pressure
mercury lamps systematically examined by modeling

AB Oxidation flow reactors (OFRs) using OH produced from low-pressure Hg lamps at 254 nm (OFR254) or both 185 and 254 nm (OFR185) are commonly used in atmospheric chemistry and other fields. OFR254 requires the addition of externally formed O-3 since OH is formed from O-3 photolysis, while OFR185 does not since O-2 can be photolyzed to produce O-3, and OH can also be formed from H2O photolysis. In this study, we use a plug-flow kinetic model to investigate OFR properties under a very wide range of conditions applicable to both field and laboratory studies. We show that the radical chemistry in OFRs can be characterized as a function of UV light intensity, H2O concentration, and total external OH reactivity (OHRext, e.g., from volatile organic compounds (VOCs), NOx, and SO2). OH exposure is decreased by added external OH reactivity. OFR185 is especially sensitive to this effect at low UV intensity due to low primary OH production. OFR254 can be more resilient against OH suppression at high injected O-3 (e.g., 70 ppm), as a larger primary OH source from O-3, as well as enhanced recycling of HO2 to OH, make external perturbations to the radical chemistry less significant. However if the external OH reactivity in OFR254 is much larger than OH reactivity from injected O-3, OH suppression can reach 2 orders of magnitude. For a typical input of 7 ppm O-3 (OHRO3 D = 10 s(-1)), 10-fold OH suppression is observed at OHRext similar to 100 s(-1), which is similar or lower than used in many laboratory studies. The range of modeled OH suppression for literature experiments is consistent with the measured values except for those with isoprene. The finding on OH suppression may have important implications for the interpretation of past laboratory studies, as applying OHexp measurements acquired under different conditions could lead to over a 1-order-of-magnitude error in the estimated OHexp. The uncertainties of key model outputs due to uncertainty in all rate constants and absorption cross-sections in the model are within +/- 25% for OH exposure and within +/- 60% for other parameters. These uncertainties are small relative to the dynamic range of outputs. Uncertainty analysis shows that most of the uncertainty is contributed by photolysis rates of O-3, O-2, and H2O and reactions of OH and HO2 with themselves or with some abundant species, i.e., O-3 and H2O2. OHexp calculated from direct integration and estimated from SO2 decay in the model with laminar and measured residence time distributions (RTDs) are generally within a factor of 2 from the plug-flow OHexp. However, in the models with RTDs, OHexp estimated from SO2 is systematically lower than directly integrated OHexp in the case of significant SO2 consumption. We thus recommended using OHexp estimated from the decay of the species under study when possible, to obtain the most appropriate information on photochemical aging in the OFR. Using HOx recycling vs. destructive external OH reactivity only leads to small changes in OHexp under most conditions.
Changing the identity (rate constant) of external OH reactants can result in substantial changes in OHexp due to different reductions in OH suppression as the reactant is consumed. We also report two equations for estimating OH exposure in OFR254. We find that the equation estimating OHexp from measured O-3 consumption performs better than an alternative equation that does not use it, and thus recommend measuring both input and output O-3 concentrations in OFR254 experiments. This study contributes to establishing a firm and systematic understanding of the gas-phase HOx and O-x chemistry in these reactors, and enables better experiment planning and interpretation as well as improved design of future reactors.

AB Three months of Doppler lidar wind measurements were obtained during the Arctic Cloud Summer Experiment on the icebreaker Oden during the summer of 2014. Such ship-borne Doppler measurements require active stabilisation to remove the effects of ship motion. We demonstrate that the combination of a commercial Doppler lidar with a custom-made motion-stabilisation platform enables the retrieval of wind profiles in the Arctic atmospheric boundary layer during both cruising and ice-breaking with statistical uncertainties comparable to land-based measurements. This held true particularly within the atmospheric boundary layer even though the overall aerosol load was very low. Motion stabilisation was successful for high wind speeds in open water and the resulting wave conditions. It allows for the retrieval of vertical winds with a random error below 0.2 ms(-1). The comparison of lidar-measured wind and radio soundings gives a mean bias of 0.3 ms(-1) (2 degrees) and a mean standard deviation of 1.1 ms(-1) (12 degrees) for wind speed (wind direction). The agreement for wind direction degrades with height. The combination of a motion-stabilised platform with a low-maintenance autonomous Doppler lidar has the potential to enable continuous long-term high-resolution ship-based wind profile measurements over the oceans.

AB Shipping traffic poses a worldwide threat to many large whale species. Spatially explicit risk assessments are increasingly being used as a tool to minimize ship-strike risk. These assessments often use static representations of shipping patterns. We used Automatic Identification System data to quantify variability in cargo shipping traffic entering and exiting San Francisco Bay, which contains some of the busiest ports in the United States, at three temporal resolutions: (1) before and after implementation of the California Air Resources Board's Ocean-Going Vessels Fuel Rule, (2) among seasons, and (3) day versus night. We used the nonparametric Mood's Median test to compare median daily distance traveled because the data were not normally distributed and the variance was not homogeneous. Our analyses show that shipping traffic off San Francisco is dynamic at both interannual and daily temporal resolutions, but that traffic was fairly consistent among the seasons considered. Our analyses emphasize the importance of economic and regulatory drivers on interannual shipping traffic patterns. Shipping traffic is expected to continue to change off the U.S. West Coast and to increase globally. These changes in shipping traffic could have implications for the risk of ships striking whales and should be included in risk assessments.

AB Linear mixtures of materials in a scene often occur because the pixel size of a sensor is relatively large and consequently they contain patches of different materials within them. This type of mixing can be thought of as areal mixing and modeled by a linear mixture model with certain constraints on the abundances. The solution to these models has received a lot of attention. However, there are more complex situations, such as scattering that occurs in mixtures of vegetation and soil, or intimate mixing of granular materials like soils. Such multiple scattering and microscopic mixtures within pixels have varying degrees of non-linearity. In such cases, a linear model is not sufficient. Furthermore, often enough, scenes may contain cases of both linear and non-linear mixing on a pixel-by-pixel basis. This study considers two approaches for use as generalized methods for un-mixing pixels in a scene that may be linear (areal mixed) or non-linear (intimately mixed). The first method is based on earlier studies that indicate non-linear mixtures in reflectance space are approximately linear in albedo space. The method converts reflectance to single-scattering albedo (SSA) according to Hapke theory assuming bidirectional scattering at nadir look angles and uses a constrained linear model on the computed albedo values. The second method is motivated by the same idea, but uses a kernel that seeks to capture the linear behavior of albedo in non-linear mixtures of materials. The behavior of the kernel method is dependent on the value of a parameter, gamma. Furthermore, both methods are dependent on the choice of endmembers, and also on RMSE (root mean square error) as a performance metric. This study compares the two approaches and pays particular attention to these dependencies. Both laboratory and aerial collections of hyperspectral imagery are used to validate the methods.

AB Improving the precision of ground-based astronomical observations is an objective of both current (e.g. PanSTARRS1) and future (e.g. Dark Energy Survey and the Large Synoptic Survey Telescope) sky surveys. An important element of this effort is to determine the optical attenuation imposed by the atmosphere. We have obtained atmospheric extinction observations from narrowband photometry (typically 10 nm bandwidth) at central wavelengths of 380 nm, 488 nm, 500 nm, 585 nm, 656 nm, 675 nm and 840 nm. The passbands were selected to measure the continuum component (predominantly from Rayleigh and aerosol scattering) of atmospheric attenuation, and to avoid molecular absorption features in the atmosphere. We compare these atmospheric extinction observations with predictions from MODTRAN5, a commonly used computer model of atmospheric optical transmission. The MODTRAN5 calculations were informed by a satellite-based determination of atmospheric ozone on the night of observations. We also adjusted the MODTRAN5 predictions of Rayleigh scattering to account for the difference between the default pressure and that measured at the observatory on the night of observations. We find excellent agreement across all passbands between the pressure-adjusted MODTRAN5 extinction model and the observations, within our typical extinction uncertainty of 0.013 mag/airmass, but only if we exclude any aerosol scattering component in the MODTRAN5 model. Even though this is a very limited test, with observations of a single star for a single night, the fact that we obtain excellent agreement between extinction measurements and the MODTRAN5 model, with no adjustable fit parameters, bodes well for exploiting MODTRAN5 to increase the precision of ground-based flux measurements.

AB The primary structure of a protein, including therapeutic monoclonal antibodies (mAbs), is a critical quality attribute that determines a great deal of its structure, function, and stability. Significant effort is devoted to determining the complete amino acid sequence of recombinant proteins of potential therapeutic benefit. The focus of this chapter is to demonstrate current, state-of-the-art, mass spectrometry-based primary structure confirmation using the recombinant human IgG 1 k NISTmAb as a representative example. A combination of intact mass analysis, top-down sequencing, IdeS fragment mass analysis, IdeS fragment (or "middle-down") sequencing, and peptide mapping are discussed with respect to their orthogonality and limitations. A historical review of the methods employed to determine the primary structure of proteins is also included for completeness.

AB Therapeutic proteins may undergo a series of modifications throughout their production, processing, and storage. These modifications can include the addition or replacement of functional groups, or structural changes such as folding, cleavage, and racemization. The presence of these modifications can affect therapeutic monoclonal antibody (mAb) biological activity, half-life, and immunogenicity. Post-translational modifications that arise during cellular expression and chemical modifications that may result during the biomanufacturing process and storage must be discovered, tracked, and evaluated for their impact on quality, safety, and efficacy. A review of the most common modifications encountered during therapeutic mAb development and their characterization using modern analytical approaches is presented, with an emphasis on mass spectrometry-based approaches. As a real-world example, a peptide mapping-based characterization study involving three independent laboratories was conducted using the reference mAb provided by the National Institute of Standards and Technology (NIST). Results from this study are discussed to provide a representative sampling of peptide mapping as it is currently applied to characterization of mAb modifications, as well as considerations to weigh when developing these experiments for qualitative and quantitative analysis

AB N-linked glycosylation is a common post-translational modification that imparts structural heterogeneity to recombinant monoclonal antibody (mAb) therapeutics. The various oligosaccharides attached to the C(H)2 domains of an IgG can impact the efficacy, safety, pharmacokinetics, and pharmacodynamics of the product. Depending on the mechanism of action of the biotherapeutic, specific glycan moieties may be deemed critical quality attributes (CQAs) and require appropriate process control and analytical strategies to ensure product quality consistency. Glycan analysis presents a significant challenge because the N-glycosylation biosynthetic pathway results in a heterogeneous population of complex branched structures at each glycosylation site. Consequently, extensive sample handling is required for analysis. At various stages of developing and manufacturing of a mAb, several levels of glycan analysis are required: (i) profiling, which can provide a quick comparative overview of the glycosylation; (ii) characterization of the glycans by type to provide particular CQAs; and (iii) full, detailed analysis, including monosaccharide sequence and linkage of the glycans, which usually requires orthogonal technologies. Glycoanalytical standards are of critical importance in evaluating the suitability of methods intended to monitor glycosylation through the lifecycle of the product. The intact NISTmAb reference material may provide an additional supplement to in-house reference standards for system suitability, operator training, and analytical method evaluation. The NISTmAb glycan population was therefore analyzed using several orthogonal approaches. The comprehensive workstreams presented here demonstrate state-of-the art technologies that are suitable for sequencing the glycans attached to mAbs throughout the lifecycle of the product.

AB Protein molecules in solution can form proteinaceous particles by a variety of aggregation processes. The size and concentration of these particles is an important quality attribute for therapeutic monoclonal antibody (mAb) solutions. In this chapter, we describe the techniques commonly used to determine size and count of particles in solution for the size range 2 gm to 100 pm. After first discussing general principles of particle formation and properties, we present general suggestions on sample handling and particle measurement, and then give detailed information on the application of the two most common techniques: light obscuration and flow imaging. The chapter concludes with a description of advanced techniques that extend the measurement size range down to 0.1 pm or characterize the particles more fully.

AB Biotherapeutics are recognized as increasingly important modalities for treating human disease. Capitalizing on advances in modern science and clinical experience with biotherapeutics, the field is rapidly expanding in seemingly orthogonal directions targeting new and increasingly sophisticated therapies, such as bispecific and conjugated monoclonal antibody products, as well as making existing therapies more affordable via the establishment biosimilar and follow-on biologics pathways. Collectively, these trends amplify the increasing demand for improvement of existing analytical methodologies as well as the development of new tools to characterize these complex biological products in greater detail. Discussion in this introductory chapter is based on the polled opinions of researchers associated with the development and testing of biotherapeutic proteins. The aim of the survey was to capture a snapshot on current perspectives on the state-of-the-art analytical methods and the need for the development of emerging technologies to address unmet or under-met characterization needs for these products.

AB In contrast to small molecule therapeutics whose conformations can be absolutely defined by constitution and stereochemistry, biopharmaceuticals are distinguished by the requirement for folding into higher order structures (secondary, tertiary, and quaternary) for therapeutic function. Whereas proper folding of a protein biologic is critical for drug efficacy, misfolding may impact drug safety by eliciting unwanted immune or other off-target patient responses. In this chapter, we review current and emerging technologies for high-resolution characterization and fingerprinting of the structure and dynamics of monoclonal antibodies (mAbs) with a focus on techniques that can provide data at or near atomic resolution, such as X-ray crystallography, nuclear magnetic resonance (NMR) and hydrogen-deuterium exchange mass spectrometry (HDX-MS). Application of these techniques is illustrated using the NISTmAb.

AB Upon reading the preceding book chapters, it is clear that comprehensive analysis of monoclonal antibody therapeutics is no easy task. These molecules embody various complex attributes, the characterization of which is a long and arduous process, yet monoclonal antibody therapeutics have taken residence as perhaps one of the most influential therapeutic classes of our time. The intent of this book series was to provide a comprehensive overview of monoclonal antibody therapeutics, using the NISTmAb as a vehicle for highlighting the characterization stages of product development. The preceding chapters represent a collaborative effort among biopharmaceutical professionals rising to this challenge. Contributors utilized the NISTmAb throughout, demonstrated the potential utility of class-specific reference materials as a means to facilitate open innovation, and identified a number of emerging research areas for future development. Conclusion of the series is therefore met with eager anticipation of continued biopharmaceutical advancement through industry-focused partnerships.

AB This review covers selected 2014 articles on the biological effects of pollutants and human physical disturbances on marine and estuarine plants, animals, ecosystems and habitats. The review, based largely on journal articles, covers field and laboratory measurement activities (bioaccumulation of contaminants, field assessment surveys, toxicity testing and biomarkers) as well as pollution issues of current interest including endocrine disrupters, emerging contaminants, wastewater discharges, dredging and disposal, etc. Special emphasis is placed on effects of oil spills and marine debris due in part to the 2010 Deepwater Horizon oil blowout in the Gulf of Mexico and the 2011 Japanese tsunami. Several topical areas reviewed in the past (ballast water and ocean acidification) were dropped this year. The focus of this review is on effects, not pollutant fate and transport. There is considerable overlap across subject areas (e.g. some bioaccumulation papers may be cited in other topical categories). Please use keyword searching of the text to locate related but distributed papers. Use this review only as a guide and please consult the original papers before citing them.

AB Evaluating the climatology and interannual variability of storm tracks in climate models represents an excellent way to evaluate their ability to simulate synoptic-scale phenomena. We generate storm tracks from the National Center for Environmental Prediction (NCEP) Climate Forecast System (CFS) model for the northern hemisphere (NH) and compare them to storm tracks generated from NCEP's reanalysis I data, the European Centre for Medium Range Prediction (ECMWF) ERA40 data, and CFS reanalysis data. To assess interannual variability, we analyze the impacts of El Nino, the North Atlantic Oscillation (NAO), and the Indian Ocean Dipole (IOD). We show that the CFS model is capable of simulating realistic storm tracks for frequency and intensity in the NH. The CFS storm tracks exhibit a reasonable response to El Nino and the NAO. However, it did not capture interannual variability for the IOD. Since one path by which storm tracks respond to external forcing is via Rossby waves due to anomalous heating, the CFS model may not be able to capture this effect especially since anomalous heating for the IOD is more local than El Nino. Our assessment is that the CFS model's storm track response is sensitive to the strength of external forcing.

AB By harnessing quantum mechanical effects we can create technology with greatly improved functionality including enhanced sensing, exponentially faster computing, the simulation of previously inaccessible quantum systems, and the secure transfer of information. In our ever more connected world, it is important that we can communicate securely, and as technology develops into the quantum regime it will become important for distant quantum processors to exchange information over a quantum network. Here we discuss how quantum information can be encoded and transferred around a such a network. We concentrate on the use of nonlinear optics to generate and manipulate photons, and present schemes for fully secure quantum communication.

AB The dramatic reduction of sea ice in the Arctic Ocean will increase human activities in the coming years. This activity will be driven by increased demand for energy and the marine resources of an Arctic Ocean accessible to ships. Oil and gas exploration, fisheries, mineral extraction, marine transportation, research and development, tourism, and search and rescue will increase the pressure on the vulnerable Arctic environment. Technologies that allow synoptic in situ observations year-round are needed to monitor and forecast changes in the Arctic atmosphere-ice-ocean system at daily, seasonal, annual, and decadal scales. These data can inform and enable both sustainable development and enforcement of international Arctic agreements and treaties, while protecting this critical environment. In this paper, we discuss multipurpose acoustic networks, including subsea cable components, in the Arctic. These networks provide communication, power, underwater, and under-ice navigation, passive monitoring of ambient sound (ice, seismic, biologic, and anthropogenic), and acoustic remote sensing (tomography and thermometry), supporting and complementing data collection from platforms, moorings, and vehicles. We support the development and implementation of regional to basin-wide acoustic networks as an integral component of a multidisciplinary in situ Arctic Ocean observatory.

AB There is now an unprecedented demand for authoritative information on the past, present, and future states of the world's snow and ice resources. The cryosphere is one of the most useful indicators of climate change, yet is one of the most under-sampled domains in the climate system. The Sixteenth World Meteorological Congress (Geneva, 2011) decided to embark on the development of a Global Cryosphere Watch (GCW) as an International Polar Year (IPY) legacy. Through WMO and its partners, GCW is now being implemented for sustained cryosphere observing and monitoring and provision of cryosphere data and-information. GCW will ensure a comprehensive, coordinated, and sustainable system of observations and information that will allow for a full understanding of the cryosphere and its changes. It will initiate a surface-based cryosphere observing network called "CryoNet" that, will establish best practices and guidelines for cryospheric measurement, data formats, and metadata by building on existing efforts. A complementary task involves developing an inventory of candidate satellite products that are mature and generally accepted by the scientific community. GCW is establishing interoperability between data management systems, and the GCW data portal will provide the ability to exchange data and information with a distributed network of providers.

AB The global extent of agriculture demands a thorough understanding of the ways it impacts the Earth system through the modification of both the physical and biological characteristics of the landscape as well as through emissions of greenhouse gases and aerosols. People use fire to manage cropland and pasture in many parts of the world, impacting both the timing and amount of fire. So far, much previous research into how these land uses affect fire regimes has focused on either individual small regions or global patterns at annual or decadal scales. Moreover, because pasture is not mapped globally at high resolution, the amount of fire associated with pasture has never been quantified as it has for cropland. The work presented here resolves the effects of agriculture - including pasture - on fire on a monthly basis for regions across the world, using globally gridded data on fire activity and land use at 0.25 degrees resolution. The first global estimate of pasture-associated fire reveals that it accounts for over 40% of annual burned area. Cropland, generally assumed to reduce fire occurrence, is shown to enhance or suppress fire at different times of year within individual regions. These results bridge important gaps in the understanding of how agriculture and associated management practices influence vegetation fire, enabling the next generation of vegetation and Earth system models more realistically incorporate these anthropogenic effects.

AB Past model studies have projected a global decrease in marine net primary production (NPP) over the 21st century, but these studies focused on the multi-model mean rather than on the large inter-model differences. Here, we analyze model-simulated changes in NPP for the 21st century under IPCC's high-emission scenario RCP8.5. We use a suite of nine coupled carbon-climate Earth system models with embedded marine ecosystem models and focus on the spread between the different models and the underlying reasons. Globally, NPP decreases in five out of the nine models over the course of the 21st century, while three show no significant trend and one even simulates an increase. The largest model spread occurs in the low latitudes (between 30 degrees S and 30 degrees N), with individual models simulating relative changes between -25 and +40 %. Of the seven models diagnosing a net decrease in NPP in the low latitudes, only three simulate this to be a consequence of the classical interpretation, i.e., a stronger nutrient limitation due to increased stratification leading to reduced phytoplankton growth. In the other four, warming-induced increases in phytoplankton growth outbalance the stronger nutrient limitation. However, temperature-driven increases in grazing and other loss processes cause a net decrease in phytoplankton biomass and reduce NPP despite higher growth rates. One model projects a strong increase in NPP in the low latitudes, caused by an intensification of the microbial loop, while NPP in the remaining model changes by less than 0.5 %. While models consistently project increases NPP in the Southern Ocean, the regional inter-model range is also very substantial. In most models, this increase in NPP is driven by temperature, but it is also modulated by changes in light, macronutrients and iron as well as grazing. Overall, current projections of future changes in global marine NPP are subject to large uncertainties and necessitate a dedicated and sustained effort to improve the models and the concepts and data that guide their development.

AB The lack of long-term monitoring programs makes it difficult to assess signs of population recovery in collapsed marine populations. Fishery-induced changes in the life history of exploited marine fishes, such as truncated size and age structure, local extirpations, reductions in age at maturity, and changes in mortality patterns, have occurred. In the present study, we explored life history aspects of totoaba Totoaba macdonaldi, almost 40 yr after a population collapse, to examine whether totoaba maintained their life history pattern and to identify the potential threats of using fishing gear (hooks, gillnets). The results of the present study indicate that the totoaba size structure was not truncated as expected in overexploited populations; indeed, it was similar to that observed in the past. Totoaba have maintained their known historical distribution range. The spatial size structure and temporal distribution followed the known migration patterns of totoaba. Total and natural mortality were similar. Contrary to recommendations for sustainable fisheries, caught fish contained a large number of juveniles, irrespective of method used. We conclude that the general life history (size structure, distribution, migration, and mortality) has not changed since the fishery collapse. However, the choice of fishing gear could compromise a positive recovery trend of the population. Moreover, poaching is a major ongoing threat to the recovery of totoaba.

AB Traditionally used source spectral-distribution or detector spectral-response based standards cannot be applied for accurate UV LED measurements. Since the CIE standardized rectangular-shape spectral response function for UV measurements cannot be realized with small spectral mismatch when using filtered detectors, the UV measurement errors can be several times ten percent or larger. The UV LEDs produce broadband radiation and both their peaks or spectral bandwidths can change significantly. The detectors used for the measurement of these LEDs also have different spectral bandwidths. In the discussed example, where LEDs with 365 nm peak are applied for fluorescent crack-recognition using liquid penetrant (non-destructive) inspection, the broadband radiometric LED (signal) measurement procedure is standardized. A UV LED irradiance-source was calibrated against an FEL lamp standard to determine its spectral irradiance. The spectral irradiance responsivity of a reference UV meter was also calibrated. The output signal of the reference UV meter was calculated from the spectral irradiance of the UV source and the spectral irradiance responsivity of the reference UV meter. From the output signal, both the integrated irradiance (in the reference plane of the reference meter) and the integrated responsivity of the reference meter were determined. Test UV meters calibrated for integrated responsivity against the reference UV meter, can be used to determine the integrated irradiance from a field UV source. The obtained 5 % (k=2) measurement uncertainty can be decreased when meters with spectral response close to a constant value are selected.

AB Recent breakthroughs in deterministic approaches to the fabrication of nanowire arrays have demonstrated the possibility of fabricating such networks using low-cost scalable methods. In this regard, we have developed a scalable growth platform for lateral fabrication of nanocrystals with high precision utilizing lattice match and symmetry. Using this planar architecture, a number of homo-and heterostructures have been demonstrated including ZnO nanowires grown over GaN. The latter combination produces horizontal, epitaxially formed crystals aligned in the plane of the substrate containing a very low number of intrinsic defects. We use such ordered structures as model systems in the interests of gauging the interfacial structural dynamics in relation to external stimuli. Nanosecond pulses of focused ion beams are used to slightly modify the substrate surface and selectively form lattice disorders in the path of nanowire growth to examine the nanocrystal, namely: its directionality and lattice defects. High resolution electron microscopies are used to reveal some interesting structural effects; for instance, a minimum threshold of surface defects that can divert nanowires. We also discuss data indicating formation of surface strains and show their mitigation during the growth process.

AB Several two-dimensional (2D) materials have been synthesized experimentally, but many theoretically predicted 2D materials are yet to be synthesized. Here, we will review a density-functional theory based framework to enable high-throughput screening of suitable substrates for the stabilization and functionalization of 2D layers. A Materials Project based open source python tool, MP Interfaces, based on this framework, is being developed to automate the search of suitable substrates as well as to characterize their effect on the structural and electronic properties of 2D materials. Lattice-matching, symmetry-matching, substrate surface termination, configuration sampling, substrate induced structural distortion and doping estimation algorithms are being developed and will be described in this article. This computational tool will be employed to identify suitable substrates for scores of technologically relevant 2D materials, leading to acceleration of their synthesis and application, and more efficient use of experimental resources.

AB This is the fourth part of a series of tutorial papers discussing various causes of measurement uncertainty in scanned particle beam instruments, and some of the solutions researched and developed at NIST and other research institutions. Scanned particle beam instruments especially the scanning electron microscope (SEM) have gone through tremendous evolution to become indispensable tools for many and diverse scientific and industrial applications. These improvements have significantly enhanced their performance and made them far easier to operate. But, the ease of operation has also fostered operator complacency. In addition, the user-friendliness has reduced the apparent need for extensive operator training. Unfortunately, this has led to the idea that the SEM is just another expensive "digital camera" or another peripheral device connected to a computer and that all of the problems in obtaining good quality images and data have been solved. Hence, one using these instruments may be lulled into thinking that all of the potential pitfalls have been fully eliminated and believing that, everything one sees on the micrograph is always correct. But, as described in this and the earlier papers, this may not be the case. Care must always be taken when reliable quantitative data are being sought. The first paper in this series discussed some of the issues related to signal generation in the SEM, including instrument calibration, electron beam-sample interactions and the need for physics-based modeling to understand the actual image formation mechanisms to properly interpret SEM images. The second paper has discussed another major issue confronting the microscopist: specimen contamination and methods to eliminate it. The third paper discussed mechanical vibration and stage drift and some useful solutions to mitigate the problems caused by them, and here, in this the fourth contribution, the issues related to specimen "charging" and its mitigation are discussed relative to dimensional metrology.

AB An investigation of an optical microscope tool characterization was presented for the quantitative measurements of deep sub-wavelength features using Fourier plane normalization method. The NIST 193 nm scatterfield microscope operating with an ArF Excimer laser, which has a capability of articulating the angular incident beam at the sample plane using an aperture scanning at the conjugate back focal plane (CBFP), was characterized through the illumination and collection optical paths. Each incident cone beam at the sample plane can be approximated as a plane wave as in Kohler configuration, simplifying the analysis of the scattered light induced by the discrete illumination beam at the sample plane. Under this approximation, the illumination and entire tool function sets were measured at the sample and imaging CCD planes, respectively, producing the collection tool function set numerically. The two sets of optical tool functions will be used to normalize scattering simulations in the Fourier space domain of the CCD image in the collection path. We investigated some aspects of the beam distributions of the illumination beam at the sample plane with respect to the change of the optical components and report the illumination and collection tool function distributions that were obtained by angular scanning of an aperture at conjugate back focal plane.

AB Metal-Organic Frameworks (MOFs) are three-dimensional coordination polymers that are well known for large pore surface area and their ability to adsorb molecules from both the gaseous and solution phases. In general, MOFs are electrically insulating, but promising opportunities for tuning the electronic structure exist because MOFs possess synthetic versatility; the metal and organic ligand subunits can be exchanged or dopant molecules can be introduced into the pore space. Two such MOFs with demonstrated electrical conductivity are Cu-3(1,3,5-benzenetricarboxylate)(2), a. k. a HKUST-1, and Cu[Ni(pyrazine-2,3-dithiolate)(2)]. Herein, these two MOFs have been infiltrated with the redox active species 7,7,8,8-tetracyanoquinodimethane (TCNQ) and iodine under solution phase conditions and shown to produce redox products within the MOF pore space. Vibrational bands assignable to TCNQ anion and triiodide anion have been observed in the Mid-IR and Terahertz ranges using FTIR Spectroscopy. The MOF samples have been further investigated by Time-Resolved Terehertz Spectroscopy (TRTS). Using this technique, the charge mobility, separation, and recombination dynamics have been followed on the picosecond time scale following photoexcitation with visible radiation. The preliminary results show that the MOF samples have small inherent photoconductivity with charge separation lifetimes on the order of a few picoseconds. In the case of HKUST-1, the MOF can also be supported by a TiO2 film and initial results show that charge injection into the TiO2 layer occurs with a comparable efficiency to the dye sensitizer N3, [cis-Bis(isothiocyanato)-bis(2,2'-bipyridyl-4,4'-dicarboxylato ruthenium(II)], and therefore this MOF has potential as a new light absorbing and charge conducting material in photovoltaic devices.

AB This paper prescribes an energy assessment methodology, including the procedure and mathematical foundation for, evaluating total use and efficiency, for mechanical and electrical product assembly processes. The majority of major manufacturers assemble components and subsystems often produced by suppliers in their supply chains. Differing measurement processes of resource use in product assembly processes yield discrepant resource use assessments. We developed a sequence of activities, including goal setting, defining baselines, measurement, analysis, reporting, evaluation, and resetting the goal for product assembly processes. These activities are to be pursued in an iterative process leading to incremental improvements towards achieving sustainable manufacturing. An application example of reflow soldering was used for verification of the proposed new process' representativeness and completeness. This methodology provides a guideline for manufacturers to make sound decisions that can be tightly integrated with their business strategy.

AB Using a machine learning approach, this study investigates the effects of machining parameters on the energy consumption of a milling machine tool, which would allow selection of optimal operational strategies to machine a part with minimum energy. Data-driven prediction models, built upon a nonlinear regression approach, can be used to gain an understanding of the effects of machining parameters on energy consumption. In this study, we use the Gaussian Process to construct the energy prediction model for a computer numerical control (CNC) milling machine tool. Energy prediction models for different machining operations are constructed based on collected data. With the collected data sets, optimum input features for model selection are identified. We demonstrate how the energy prediction models can be used to compare the energy consumption for the different operations and to estimate the total energy usage for machining a generic part. We also present an uncertainty analysis to develop confidence bounds for the prediction model and to provide insight into the vast parameter space and training required to improve the accuracy of the model. Generic parts are machined to test and validate the prediction model constructed using the Gaussian Process and we consistently achieve an accuracy of over 95 % on the total predicted energy.

AB Polymeric multilayer backsheets protect the photovoltaic modules from damage of moisture and ultraviolet (UV) while providing electrical insulation. Due to the multilayer structures, the properties of the inner layers of the backsheets, including their interfaces, during weathering are not well known. In this study, a commercial type of PPE (polyethylene terephthalate (PET)/PET/ethylene vinyl acetate (EVA)) backsheet films was selected as a model system for a depth profiling study of mechanical properties of a backsheet film during UV exposure. The NIST SPHERE (Simulated Photodegradation via High Energy Radiant Exposure) was used for the accelerated laboratory exposure of the materials with UV at 85 degrees C and two relative humidities (RH) of 5 % (dry) and 60 % (humid). Cryomicrotomy was used to obtain cross-sectional PPE samples. Mechanical depth profiling of the cross-sections of aged and unaged samples was conducted by nanoindentation, and a peak-force based quantitative nanomechanical atomic force microscopy (QNM-AFM) mapping techniquewas used to investigate the microstructure and adhesion properties of the adhesive tie layers. The nanoindentation results show the stiffening of the elastic modulus in the PET outer and pigmented EVA layers. From QNM-AFM, the microstructures and adhesion properties of the adhesive layers between PET outer and core layers and between PET core and EVA inner layers are revealed and found to degrade significantly after aging under humidity environment. The results from mechanical depth profiling of the PPE backsheet are further related to the previous chemical depth profiling of the same material, providing new insights into the effects of accelerated UV and humidity on the degradation of multilayer backsheet.

AB The channel crack and delamination phenomena that occurred during tensile tests were utilized to study surface cracking and delamination properties of a multilayered backsheet. A model sample of commercial PPE (polyethylene terephthalate (PET)/PET/ethylene vinyl acetate (EVA)) backsheet was studied. Fragmentation testing was performed after accelerated aging with and without ultraviolet (UV) irradiation in two relative humidity (RH) levels (5 % RH and 60 % RH) at elevated temperature (85 degrees C) conditions for 11 days and 22 days. Results suggest that the embrittled surface layer resulting from the UV photo-degradation is responsible for surface cracking when the strain applied on the sample is far below the yielding strain (2.2 %) of the PPE sample. There was no surface cracking observed on the un-aged sample and samples aged without UV irradiation. According to the fragmentation testing results, the calculated fracture toughness (KIC) values of the embrittled surface layer are as low as 0.027 MPa.m(1/2) to 0.104 MPa.m(1/2), depending on the humidity levels and aging times. Surface analysis using attenuated total reflectance Fourier transform infrared and atomic force microscopy shows the degradation mechanism of the embrittled surface layer is a combination of the photo-degradation within a certain degradation depth and the moisture erosion effect depending on the moisture levels. Specifically, UV irradiation provides a chemical degradation effect while moisture plays a synergistic effect on surface erosion, which influences surface roughness after aging. Finally, there was no delamination observed during tensile testing in this study, suggesting the surface cracking problem is more significant than the delamination for the PPE backsheet material and conditions tested here.

AB During landfall of extratropical cyclones between 2005 and 2011, nearly 1400 precipitation samples were collected at intervals of 30-min time resolution with novel automated collectors at four NOAA sites in northern California [Alta (ATA), Bodega Bay (BBY), Cazadero (CZD) and Shasta Dam (STD)] during 43 events. Substantial decreases were commonly followed hours later by substantial increases in hydrogen isotopic composition (delta H-2(VSMOW) where VSMOW is Vienna Standard Mean Ocean Water) and oxygen isotopic composition (delta O-18(VSMOW)) of precipitation. These variations likely occur as pre-cold frontal precipitation generation transitions from marine vapour masses having low rainout to cold cloud layers having much higher rainout (with concomitant brightband signatures measured by an S-band profiling radar and lower delta H-2(VSMOW) values of precipitation), and finally to shallower, warmer precipitating clouds having lower rainout (with non-brightband signatures and higher delta H-2(VSMOW) values of precipitation), in accord with 'seeder-feeder' precipitation. Of 82 intervals identified, a remarkable 100.5 parts per thousand decrease in delta H-2(VSMOW) value was observed for a 21 January 2010 event at BBY. Of the 61 intervals identified with increases in delta H-2(VSMOW) values as precipitation transitioned to shallower, warmer clouds having substantially less rainout (the feeder part of the seeder-feeder mechanism), a remarkable increase in delta H-2(VSMOW) value of precipitation of 82.3 parts per thousand was observed for a 10 February 2007 event at CZD. All CZD and ATA events having delta H-2(VSMOW) values of precipitation below -105 parts per thousand were atmospheric rivers (ARs), and of the 13 events having delta H-2(VSMOW) values of precipitation below -80 parts per thousand, 77 % were ARs. Cloud echo-top heights (a proxy for atmospheric temperature) were available for 23 events. The mean echo-top height is greater for higher rainout periods than that for lower rainout periods in 22 of the 23 events. The lowest delta H-2(VSMOW) of precipitation of 28 CZD events was -137.9 parts per thousand on 16 February 2009 during an AR with cold precipitating clouds and very high rainout with tops >6.5 km altitude. An altitude effect of -2.5 parts per thousand per 100 m was measured from BBY and CZD delta H-2(VSMOW) data and of -1.8 parts per thousand per 100 m for CZD and ATA delta H-2(VSMOW) data. We present a new approach to categorise rainfall intervals using delta H-2(VSMOW) values of precipitation and rainfall rates. We term this approach the algorithmic-isotopic categorisation of rainfall, and we were able to identify higher rainout and/or lower rainout periods during all events in this study. We conclude that algorithmic-isotopic categorisation of rainfall can enable users to distinguish between tropospheric vapour masses having relatively high rainout (typically with brightband rain and that commonly are ARs) and vapour masses having lower rainout (commonly with non-brightband rain).

In order to determine if these issues were met, the design is analyzed and compared against alternate methods of writing-in a candidate's name. An experiment was performed to assess two aspects of the multimodal system: speech interaction and switch interaction. The research intends to capture and analyze the efficiency and effectiveness of writing-in a candidate's name anonymously through multimodal interactions. Though the essence of this research embodies universal of design for everyone everywhere, the design and experiments put forth in this paper will focus on the U.S. voting population.

TI Assessment of long-term WRF-CMAQ simulations for understanding direct
aerosol effects on radiation "brightening" in the United States

AB Long-term simulations with the coupled WRF-CMAQ (Weather Research and Forecasting-Community Multi-scale Air Quality) model have been conducted to systematically investigate the changes in anthropogenic emissions of SO2 and NOx over the past 16 years (1995-2010) across the United States (US), their impacts on anthropogenic aerosol loading over North America, and subsequent impacts on regional radiation budgets. In particular, this study attempts to determine the consequences of the changes in tropospheric aerosol burden arising from substantial reductions in emissions of SO2 and NOx associated with control measures under the Clean Air Act (CAA) especially on trends in solar radiation. Extensive analyses conducted by Gan et al. (2014a) utilizing observations (e.g., SURFRAD, CASTNET, IMPROVE, and ARM) over the past 16 years (1995-2010) indicate a shortwave (SW) radiation (both all-sky and clear-sky) "brightening" in the US. The relationship of the radiation brightening trend with decreases in the aerosol burden is less apparent in the western US. One of the main reasons for this is that the emission controls under the CAA were aimed primarily at reducing pollutants in areas violating national air quality standards, most of which were located in the eastern US, while the relatively less populated areas in the western US were less polluted at the beginning of this study period. Comparisons of model results with observations of aerosol optical depth (AOD), aerosol concentration, and radiation demonstrate that the coupled WRF-CMAQ model is capable of replicating the trends well even though it tends to underestimate the AOD. In particular, the sulfate concentration predictions were well matched with the observations. The discrepancies found in the clear-sky diffuse SW radiation are likely due to several factors such as the potential increase of ice particles associated with increasing air traffic, the definition of "clear-sky" in the radiation retrieval methodology, and aerosol semi-direct and/or indirect effects which cannot be readily isolated from the observed data.

AB Hourly averaged aerosol optical properties (AOPs) measured over the years 2010-2013 at four continental North American NOAA Earth System Research Laboratory (NOAA/ESRL) cooperative aerosol network sites - Southern Great Plains near Lamont, OK (SGP), Bondville, IL (BND), Appalachian State University in Boone, NC (APP), and Egbert, Ontario, Canada (EGB) are analyzed. Aerosol optical properties measured over 1996-2009 at BND and 1997-2009 at SGP are also presented. The aerosol sources and types in the four regions differ enough so as to collectively represent rural, anthropogenically perturbed air conditions over much of eastern continental North America. Temporal AOP variability on monthly, weekly, and diurnal timescales is presented for each site. Differences in annually averaged AOPs and those for individual months at the four sites are used to examine regional AOP variability. Temporal and regional variability are placed in the context of reported aerosol chemistry at the sites, meteorological measurements (wind direction, temperature), and reported regional mixing layer heights. Basic trend analysis is conducted for selected AOPs at the long-term sites (BND and SGP). Systematic relationships among AOPs are also presented.
Seasonal variability in PM1 (sub-1 mu m particulate matter) scattering and absorption coefficients at 550 nm (sigma(sp) and sigma(ap), respectively) and most of the other PM1 AOPs is much larger than day of week and diurnal variability at all sites. All sites demonstrate summer sigma(sp) and sigma(ap) peaks. Scattering coefficient decreases by a factor of 2-4 in September-October and coincides with minimum single-scattering albedo (omega(0)) and maximum hemispheric backscatter fraction (b). The covariation of omega(0) and b lead to insignificant annual cycles in top-of-atmosphere direct radiative forcing efficiency (DRFE) at APP and SGP. Much larger annual DRFE cycle amplitudes are observed at EGB (similar to 40 %) and BND (similar to 25 %), with least negative DRFE in September-October at both sites. Secondary winter peaks in sigma(sp) are observed at all sites except APP. Amplitudes of diurnal and weekly cycles in sigma(ap) at the sites are larger for all seasons than those of sigma(sp), with the largest differences occurring in summer. The weekly and diurnal cycle amplitudes of most intensive AOPs (e.g., those derived from ratios of measured sigma(sp) and sigma(ap)) are minimal in most cases, especially those related to parameterizations of aerosol size distribution.
Statistically significant trends in sigma(sp) (decreasing), PM1 scattering fraction (decreasing), and b (increasing) are found at BND from 1996 to 2013 and at SGP from 1997 to 2013. A statistically significant decreasing trend in PM10 scattering Angstrom exponent is also observed for SGP but not BND. Most systematic relationships among AOPs are similar for the four sites and are adequately described for individual seasons by annually averaged relationships, although relationships involving absorption Angstrom exponent vary with site and season.

AB Dust aerosols affect human life, ecosystems, atmospheric chemistry and climate in various aspects. Some studies have revealed intensified dust activity in the western US during the past decades despite the weaker dust activity in non-US regions. It is important to extend the historical dust records, to better understand their temporal changes, and to use such information to improve the daily dust forecasting skill as well as the projection of future dust activity under the changing climate. This study develops dust records in Arizona in 2005-2013 using multiple observation data sets, including in situ measurements at the surface Air Quality System (AQS) and Interagency Monitoring of Protected Visual Environments (IMPROVE) sites, and level 2 deep blue aerosol product by the Moderate Resolution Imaging Spectroradiometer. The diurnal and inter-annual variability of identified dust events are shown related to observed weather patterns (e.g., wind and soil moisture) and surface conditions (e.g., land cover type and vegetation conditions), suggesting a potential for use of satellite soil moisture and land products to help interpret and predict dust activity. Backtrajectories computed using NOAA's Hybrid Single Particle Lagrangian Integrated Trajectory (HYSPLIT) model indicate that the Sonoran and Chihuahuan deserts are important dust source regions during identified dust events in Phoenix, Arizona. Finally, we assess the impact of a recent strong dust event on western US air quality, using various observational and modeling data sets, during a period with a stratospheric ozone intrusion event. The capability of the current US National Air Quality Forecasting Capability (NAQFC) Community Multi-scale Air Quality (CMAQ) modeling system to represent the magnitude and the temporal variability of aerosol concentrations is evaluated for this event. Directions for integrating observations to further improve dust emission modeling in CMAQ are also suggested.

AB A simple electrochemical process for submonolayer deposition of ultrathin catalytic Ir films is demonstrated. This method enables effective utilization of one of nature's rarest elements while different substrates facilitate the exploration of promising bimetallic catalysts for a sustainable hydrogen economy. Semi-coherent Ir films were deposited on Au, Pt and Ni substrates using K3IrCl6-Na2SO4-H2SO4 electrolytes operated between 40 degrees C and 70 degrees C. However, the deposition reaction is quenched at the onset of H-2 production where adsorbed H blocks the reduction of IrCl6-xH2Oxx-3 to Ir. The electrode can be reactivated for further deposition by pulsing the potential to more positive values where adsorbed H is oxidized. The electrocatalytic activity of ultrathin Ir and Pt films, and combinations thereof, were examined as function of the number of self-terminating deposition pulses. The ultrathin films match or exceed the best reported activity metrics for hydrogen oxidation in alkaline media and oxygen evolution in acid.

AB Solid electrolytes with sufficiently high conductivities and stabilities are the elusive answer to the inherent shortcomings of organic liquid electrolytes prevalent in today's rechargeable batteries. We recently revealed a novel fast-ion-conducting sodium salt, Na2B12H12, which contains large, icosahedral, divalent B12H122- anions that enable impressive superionic conductivity, albeit only above its 529 K phase transition. Its lithium congener, Li2B12H12, possesses an even more technologically prohibitive transition temperature above 600 K. Here we show that the chemically related LiCB11H12 and NaCB11H12 salts, which contain icosahedral, monovalent CB11H12- anions, both exhibit much lower transition temperatures near 400 K and 380 K, respectively, and truly stellar ionic conductivities (>0.1 S cm(-1)) unmatched by any other known polycrystalline materials at these temperatures. With proper modifications, we are confident that room-temperature-stabilized superionic salts incorporating such large polyhedral anion building blocks are attainable, thus enhancing their future prospects as practical electrolyte materials in next-generation, all-solid-state batteries.

DT Editorial Material
AB With the continued increase in commercial and industrial use of nanomaterials, their interactions with biological interfaces in applied and natural systems will need to be understood to improve efficacy and assess ecological risks. Model systems are currently being developed that can be used to evaluate nanomaterial or cellular characteristics affecting the mechanism of attachment and uptake. The development of methods that can provide higher throughput for surveying specific interactions is also valuable for evaluating risk and binning systems of similar behavior, which can direct further detailed examination of specific systems. The first highlighted study demonstrates the development of supported phase segregated lipid bilayers with thoroughly characterized structures, which were subsequently used for evaluating specific chemical and morphological properties contributing to observed nanoparticle-membrane interactions. The second study employs a high throughput approach for evaluating lipid bilayer-nanoparticle interactions by using arrays of bilayers on a chip. The arrays provide a large parameter space to be examined, which included changes in both solution and membrane composition. The last study demonstrates the importance of the nanoparticles' mechanical properties on uptake by the cellular membrane using a combined experimental and computational approach.

AB The central mission for the development of the National Institute of Standards and Technology/National Institutes of Health/ Environmental Protection Agency Mass Spectral Library is the acquisition of reference gas chromatography-mass spectrometry data for important compounds and their chemical modification products. The addition of reliable reference data of various derivatives of amino acids to The Library, and the study of their behavior under electron ionization conditions may be useful for their identification, structure elucidation-, and a better understanding of the data obtained when the same derivatives are subjected to other ionization methods-. N-Alkyl-N-perfluoroacyl derivatives of amino acids readily produce previously unreported alkylnitrilium cations of composition [HC N-alkyl](+). Homologous [HC N-aryl](+) cations are typical for corresponding N-aryl analogs. The formation of other ions characteristic for these derivatives involves oxygen rearrangement giving rise to ions [CnF2n+1-C N+-CnH2n+ 1] and [CnF2n+1-C N+-aryl]. The introduction of an N-benzyl substituent in a molecule favors a process producing benzylidene iminium cations. L-Threonine and L-cysteine derivatives exhibit more fragmentation pathways not typical for other alpha-amino acids; additionally, the N-omega-amino group in l-lysine directs the dissociation process and provides structural information on the substitution at the amino functions in the molecule.

AB Methylammonium lead iodide (CH3NH3PbI3) based solar cells have shown impressive power conversion efficiencies of above 20%. However, the microscopic mechanism of the high photovoltaic performance is yet to be fully understood. Particularly, the dynamics of CH3NH3+ cations and their impact on relevant processes such as charge recombination and exciton dissociation are still poorly understood. Here, using elastic and quasi-elastic neutron scattering techniques and group theoretical analysis, we studied rotational modes of the CH3NH3+ cation in CH3NH3PbI3. Our results show that, in the cubic (T > 327 K) and tetragonal (165 K < T < 327 K) phases, the CCH3NH3+ ions exhibit four-fold rotational symmetry of the C-N axis (C-4) along with three-fold rotation around the C-N axis (C-3), while in the orthorhombic phase (T < 165 K) only C-3 rotation is present. At around room temperature, the characteristic relaxation times for the C-4 rotation are found to be tau(C4) approximate to 5 ps while for the C-3 rotation tau(C3) approximate to 1 ps. The T-dependent rotational relaxation times were fitted with Arrhenius equations to obtain activation energies. Our data show a close correlation between the C-4 rotational mode and the temperature dependent dielectric permittivity. Our findings on the rotational dynamics of CH3NH3+ and the associated dipole have important implications for understanding the low exciton binding energy and a slow charge recombination rate in CH3NH3PbI3 which are directly relevant for the high solar cell performance.

AB Additive Manufacturing (AM) processes intertwine aspects of many different engineering-related disciplines, such as material metrology, design, in-situ and off-line measurements, and controls. Due to the increasing complexity of AM systems and processes, data cannot be shared among heterogeneous systems because of a lack of a common vocabulary and data interoperability methods. This paper aims to address insufficiencies in laser-based Powder Bed Fusion (PBF), a specific AM process, data representations to improve data management and reuse in PBF. Our approach is to formally decompose the processes and align PBF process-specifics with information elements as fundamental requirements for representing process-related data. The paper defines the organization and flow of process information. After modeling selected PBF processes and sub-processes as activities, we discuss requirements for the development of more advanced process data models that provide common terminology and process knowledge for managing data from various stages in AM.

ID LIMIT-THEOREM; INDIFFERENTIABILITY
AB In this work, we present a modification of a well-established measure of dependence appropriate for the analysis of stopping times for adversarial processes on cryptographic primitives. We apply this measure to construct generic criteria for the ideal behavior of fixed functions in both the random oracle and ideal permutation setting. More significantly, we provide a nontrivial extension of the notion of hash function indifferentiability, transporting the theory from the status of providing security arguments for protocols utilizing ideal primitives into the more realistic setting of protocol assurance with fixed functions. The methodology this measure introduces to indifferentiability analysis connects the security of a hash function with an indifferentiable mode to the security of the underlying compression function in a quantitative way; thus, we prove that dependence results on cryptographic primitives provide a direct means of determining the practical resistance or vulnerability of protocols employing such primitives.

DE Network forensics; network attacks; evidence graph; admissibility
AB Many attackers tend to use sophisticated multi-stage and/or multi-host attack techniques and anti-forensic tools to cover their traces. Due to the limitations of current intrusion detection and network forensic analysis tools, reconstructing attack scenarios from evidence left behind by attackers of enterprise systems is challenging. In particular, reconstructing attack scenarios using intrusion detection system alerts and system logs that have too many false positives is a big challenge.
This chapter presents a model and an accompanying software tool that systematically addresses the reconstruction of attack scenarios in a manner that could stand up in court. The problems faced in such reconstructions include large amounts of data (including irrelevant data), missing evidence and evidence corrupted or destroyed by anti-forensic techniques. The model addresses these problems using various methods, including mapping evidence to system vulnerabilities, inductive reasoning and abductive reasoning, to reconstruct attack scenarios. The Prolog-based system employs known vulnerability databases and an anti-forensic database that will eventually be extended to a standardized database like the NIST National Vulnerability Database. The system, which is designed for network forensic analysis, reduces the time and effort required to reach definite conclusions about how network attacks occurred.

ID IMPACTS
AB In May 2013, a massive ice jam on the Yukon River caused flooding that destroyed much of the infrastructure in the Interior Alaska village of Galena and forced the long-term evacuation of nearly 70% of its residents. This case study compares the communication efforts of the out-of-state emergency response agents with those of the Alaska River Watch program, a state-operated flood preparedness and community outreach initiative. For over 50 years, the River Watch program has been fostering long-lasting, open, and reciprocal communication with flood prone communities, as well as local emergency management and tribal officials. By taking into account cultural, ethnic, and socioeconomic features of rural Alaskan communities, the River Watch program was able to establish and maintain a sense of partnership and reliable communication patterns with communities at risk. As a result, officials and residents in these communities are open to information and guidance from the River Watch during the time of a flood, and thus are poised to take prompt actions. By informing communities of existing ice conditions and flood threats on a regular basis, the River Watch provides effective mitigation efforts in terms of ice jam flood effects reduction. Although other ice jam mitigation attempts had been made throughout US and Alaskan history, the majority proved to be futile and/or cost-ineffective. Galena, along with other rural riverine Alaskan communities, has to rely primarily on disaster response and recovery strategies to withstand the shock of disasters. Significant government funds are spent on these challenging efforts and these expenses might be reduced through an improved understanding of both the physical and climatological principals behind river ice breakup and risk mitigation. This study finds that long term dialogue is critical for effective disaster response and recovery during extreme hydrological events connected to changing climate, timing of river ice breakup, and flood occurrence in rural communities of the Far North.

AB The removal of impassable dams can affect stream fish communities in many ways, including allowing previously separated anadromous and resident life history types to intermingle. Recolonization of steelhead Oncorhynchus mykiss (anadromous Rainbow Trout) into areas that were previously occupied solely by resident conspecifics presents a challenge for monitoring because (1) staging or spawning adults may be difficult to directly observe; and (2) the offspring of the two life history forms are indistinguishable during early life. We evaluated the utility of using redd attributes, fry (age-0) size, and fry density to distinguish the presence of steelhead and Rainbow Trout in the Elwha River, Washington. Redd area and substrate size differed between forms: steelhead redds were significantly larger and had a greater median substrate particle size than Rainbow Trout redds. Fry density was significantly higher in steelhead spawning reaches than in Rainbow Trout reaches during both survey years (2010 and 2011). Steelhead fry tended to be slightly larger than Rainbow Trout fry but not significantly so in either year. Additionally, otolith microchemical analyses indicated that all fry collected from newly colonized habitat were of steelhead maternal origin, and these fish were intermediate in size to the steelhead and Rainbow Trout fry collected prior to dam removal. Thus, fry size may not effectively differentiate parental origin despite the tendency of anadromous parents to be larger and to spawn earlier than residents. Redd attributes and fry density may be useful for evaluating the spatial distributions and relative abundances of steelhead and Rainbow Trout after dam removal. Our results have implications for other dam removal projects and other monitored species.

AB The National Geodetic Survey (NGS) is responsible for maintaining access and standards of accuracy for positioning within the National Spatial Reference System (NSRS). There are many Real Time Networks (RTNs) around the U.S., and users of such RTN's desire positions that are consistent to an acceptable standard of accuracy within the NSRS.
Some RTNs rely upon the broader Continuously Operating Reference Station (CORS) Network to provide control. Most of the CORS network is not owned nor operated by NGS, but NGS collects and archives information for these sites for the use of others. There has been a great deal of interest expressed by some states and agencies in adding more CORS sites, potentially including some RTN base stations. While this is laudable, it is also beyond the current capability for NGS to maintain such a larger network. Current NGS guidelines [1] state that CORS stations should be spaced 70 km or more apart. This is too sparse for most RTN applications due to the degradation of the corrector signals with distance - especially in the presence of limiting topography.
As an alternative, Online Positioning User Service (OPUS) tools are being developed to provide rapid and accurate monitoring of RTN positions. An OPUS-Static (OPUS-S) solution generates multiple single baseline solutions to obtain location information. Processing of a significant period of data (24-48 hours) for a RTN master station could be automated for data submission from the RTN operator either daily or monthly. These data could then be shared via OPUS, where they would be stored in the OPUS-Database (OPUS-DB). As a final step for evaluating the RTN base station, a RTN tool is being developed to capture and simplify the above processes to ensure that RTN base stations can be monitored for consistency within the NSRS. The validity of RTN positions can ultimately be checked by the RTN users simply by occupying a published bench marks and comparing the RTN-derived position with the published coordinate. This RTN Validator tool will be developed throughout this year and is intended to be released for testing in 2015.
NGS will not maintain or provide augmentation service greater than the above stated 70 km guideline except for special cases. However, NGS will work with agencies and localities seeking to develop their own denser networks to meet real time positioning needs.

Gel structure has been probed by detailed SANS measurements which indicate a surprising structure evolution on thermal cycling, not seen for hydrocarbon analogues. The SANS data are complemented by the single crystal X-ray structure of one fluorinated gelator.

ID HYDRATION-WATER DYNAMICS; NEUTRON-SCATTERING; PROTEIN DYNAMICS;

AB Electrostatic interactions of RNA are at the center of determining the dynamical flexibility and structural stability. By analysing neutron scattering spectroscopy, we show that fast dynamics of hydrated tRNA on ps to ns timescales increases with stronger charge screening, while its structural stability either increases or remains largely unchanged. An unprecedented electrostatic threshold for the onset of additional flexibility is induced from the correlation between the charge-screening density of counterions and the promoted dynamical properties. The results demonstrate that the enhanced dynamical flexibility of tRNA originates from local conformational relaxation coupled with stabilized charge screening rather than governed by fluctuation of hydrated counterions. The present study casts light on the specificity of electrostatic interactions in the thermodynamic balance between the dynamical flexibility and structural stability of RNA.

AB Occurrences of jet engine power loss and damage have been associated with flight through fully glaciated deep convection at -10 to -50 degrees C. Power loss events commonly occur during flight through radar reflectivity (Z(e)) less than 20-30 dBZ and no more than moderate turbulence, often overlying moderate to heavy rain near the surface. During 2010-2012, Airbus carried out flight tests seeking to characterize the highest ice water content (IWC) in such low-Z(e) regions of large, cold-topped storm systems in the vicinity of Cayenne, Darwin, and Santiago. Within the highest IWC regions encountered, at typical sampling elevations (circa 11 km), the measured ice size distributions exhibit a notably narrow concentration of mass over area-equivalent diameters of 100-500 mu m. Given substantial and poorly quantified measurement uncertainties, here we evaluate the consistency of the Airbus in situ measurements with ground-based profiling radar observations obtained under quasi-steady, heavy stratiform rain conditions in one of the Airbus-sampled locations. We find that profiler-observed radar reflectivities and mean Doppler velocities at Airbus sampling temperatures are generally consistent with those calculated from in situ size-distribution measurements. We also find that column simulations using the in situ size distributions as an upper boundary condition are generally consistent with observed profiles of Z(e), mean Doppler velocity (MDV), and retrieved rain rate. The results of these consistency checks motivate an examination of the microphysical pathways that could be responsible for the observed size-distribution features in Ackerman et al. (2015).

AB Marine-produced short-lived trace gases such as dibromomethane (CH2Br2), bromoform (CHBr3), methyliodide (CH3I) and dimethyl sulfide (DMS) significantly impact tropospheric and stratospheric chemistry. Describing their marine emissions in atmospheric chemistry models as accurately as possible is necessary to quantify their impact on ozone depletion and Earth's radiative budget. So far, marine emissions of trace gases have mainly been prescribed from emission climatologies, thus lacking the interaction between the actual state of the atmosphere and the ocean. Here we present simulations with the chemistry climate model EMAC (ECHAM5/MESSy Atmospheric Chemistry) with online calculation of emissions based on surface water concentrations, in contrast to directly prescribed emissions. Considering the actual state of the model atmosphere results in a concentration gradient consistent with model real-time conditions at the ocean surface and in the atmosphere, which determine the direction and magnitude of the computed flux. This method has a number of conceptual and practical benefits, as the modelled emission can respond consistently to changes in sea surface temperature, surface wind speed, sea ice cover and especially atmospheric mixing ratio. This online calculation could enhance, dampen or even invert the fluxes (i.e. deposition instead of emissions) of very short-lived substances (VSLS). We show that differences between prescribing emissions and prescribing concentrations (28% for CH2Br2 to +11% for CHBr3) result mainly from consideration of the actual, time-varying state of the atmosphere. The absolute magnitude of the differences depends mainly on the surface ocean saturation of each particular gas. Comparison to observations from aircraft, ships and ground stations reveals that computing the air-sea flux interactively leads in most of the cases to more accurate atmospheric mixing ratios in the model compared to the computation from prescribed emissions. Calculating emissions online also enables effective testing of different air-sea transfer velocity (k) parameterizations, which was performed here for eight different parameterizations. The testing of these different k values is of special interest for DMS, as recently published parameterizations derived by direct flux measurements using eddy covariance measurements suggest decreasing k values at high wind speeds or a linear relationship with wind speed. Implementing these parameterizations reduces discrepancies in modelled DMS atmospheric mixing ratios and observations by a factor of 1.5 compared to parameterizations with a quadratic or cubic relationship to wind speed.

TI Characterization of a real-time tracer for isoprene epoxydiols-derived
secondary organic aerosol (IEPOX-SOA) from aerosol mass spectrometer

AB Substantial amounts of secondary organic aerosol (SOA) can be formed from isoprene epoxydiols (IEPOX), which are oxidation products of isoprene mainly under low-NO conditions. Total IEPOX-SOA, which may include SOA formed from other parallel isoprene oxidation pathways, was quantified by applying positive matrix factorization (PMF) to aerosol mass spectrometer (AMS) measurements. The IEPOX-SOA fractions of organic aerosol (OA) in multiple field studies across several continents are summarized here and show consistent patterns with the concentration of gas-phase IEPOX simulated by the GEOS-Chem chemical transport model. During the Southern Oxidant and Aerosol Study (SOAS), 78% of PMF-resolved IEPOX-SOA is accounted by the measured IEPOX-SOA molecular tracers (2-methyltetrols, C5-Triols, and IEPOX-derived organosulfate and its dimers), making it the highest level of molecular identification of an ambient SOA component to our knowledge. An enhanced signal at C5H6O+ (m/z 82) is found in PMF-resolved IEPOX-SOA spectra. To investigate the suitability of this ion as a tracer for IEPOX-SOA, we examine fC(5)H(6)O (fC(5)H(6)O = C5H6O+ / OA) across multiple field, chamber, and source data sets. A background of similar to 1.7 +/- 0.1 parts per thousand (parts per thousand = parts per thousand) is observed in studies strongly influenced by urban, biomass-burning, and other anthropogenic primary organic aerosol (POA). Higher background values of 3.1 +/- 0.6 parts per thousand are found in studies strongly influenced by monoterpene emissions. The average laboratory monoterpene SOA value (5.5 +/- 2.0 parts per thousand) is 4 times lower than the average for IEPOX-SOA (22 +/- 7 parts per thousand), which leaves some room to separate both contributions to OA. Locations strongly influenced by isoprene emissions under low-NO levels had higher fC(5)H(6)O (similar to 6.5 +/- 2.2 parts per thousand on average) than other sites, consistent with the expected IEPOX- SOA formation in those studies. fC(5)H(6)O in IEPOX- SOA is always elevated (12-40 parts per thousand) but varies substantially between locations, which is shown to reflect large variations in its detailed molecular composition. The low fC(5)H(6)O (< 3 parts per thousand) reported in non-IEPOX-derived isoprene-SOA from chamber studies indicates that this tracer ion is specifically enhanced from IEPOX- SOA, and is not a tracer for all SOA from isoprene. We introduce a graphical diagnostic to study the presence and aging of IEPOX- SOA as a triangle plot of f(CO2) vs. fC(5)H(6)O. Finally, we develop a simplified method to estimate ambient IEPOX- SOA mass concentrations, which is shown to perform well compared to the full PMF method. The uncertainty of the tracer method is up to a factor of similar to 2, if the fC(5)H(6)O of the local IEPOX- SOA is not available. When only unit mass-resolution data are available, as with the aerosol chemical speciation monitor (ACSM), all methods may perform less well because of increased interferences from other ions at m/z 82. This study clarifies the strengths and limitations of the different AMS methods for detection of IEPOX- SOA and will enable improved characterization of this OA component.

TI Impacts of AMSU-A, MHS and IASI data assimilation on temperature and

AB Using NOAA's Gridpoint Statistical Interpolation (GSI) data assimilation system and NCAR's Advanced Research WRF (Weather Research and Forecasting) (ARW-WRF) regional model, six experiments are designed by (1) a control experiment (CTRL) and five data assimilation (DA) experiments with different data sets, including (2) conventional data only (CON); (3) microwave data (AMSU-A + MHS) only (MW); (4) infrared data (IASI) only (IR); (5) a combination of microwave and infrared data (MWIR); and (6) a combination of conventional, microwave and infrared observation data (ALL). One-month experiments in July 2012 and the impacts of the DA on temperature and moisture forecasts at the surface and four vertical layers over the western United States have been investigated. The four layers include lower troposphere (LT) from 800 to 1000 hPa, middle troposphere (MT) from 400 to 800 hPa, upper troposphere (UT) from 200 to 400 hPa, and lower stratosphere (LS) from 50 to 200 hPa. The results show that the regional GSI-WRF system is underestimating the observed temperature in the LT and overestimating in the UT and LS. The MW DA reduced the forecast bias from the MT to the LS within 30 h forecasts, and the CON DA kept a smaller forecast bias in the LT for 2-day forecasts. The largest root mean square error (RMSE) is observed in the LT and at the surface (SFC). Compared to the CTRL, the MW DA produced the most positive contribution in the UT and LS, and the CON DA mainly improved the temperature forecasts at the SFC. However, the IR DA gave a negative contribution in the LT. Most of the observed humidity in the different vertical layers is overestimated in the humidity forecasts except in the UT. The smallest bias in the humidity forecast occurred at the SFC and in the UT. The DA experiments apparently reduced the bias from the LT to UT, especially for the IR DA experiment, but the RMSEs are not reduced in the humidity forecasts. Compared to the CTRL, the IR DA experiment has a larger RMSE in the moisture forecast, although the smallest bias is found in the LT and MT.

AB With the recent advent of commercial laser absorption spectrometers, field studies measuring stable isotope ratios of hydrogen and oxygen in water vapor have proliferated. These pioneering analyses have provided invaluable feedback about best strategies for optimizing instrumental accuracy, yet questions still remain about instrument performance and calibration approaches for multi-year field deployments. With clear scientific potential for using these instruments to carry out monitoring of the hydrological cycle, this study examines the long-term stability of the isotopic biases associated with three cavity-enhanced laser absorption spectrometers - calibrated with different systems and approaches - at two remote field sites: Mauna Loa Observatory, Hawaii, USA, and Greenland Environmental Observatory, Summit, Greenland. The analysis pays particular attention to the stability of measurement dependencies on water vapor concentration and also evaluates whether these so-called concentration dependences are sensitive to statistical curve-fitting choices or measurement hysteresis. The results suggest evidence of monthly-to-seasonal concentration-dependence variability - which likely stems from low signal-to-noise at the humidity-range extremes - but no long-term directional drift. At Mauna Loa, where the isotopic analyzer is calibrated by injection of liquid water standards into a vaporizer, the largest source of inaccuracy in characterizing the concentration dependence stems from an insufficient density of calibration points at low water vapor volume mixing ratios. In comparison, at Summit, the largest source of inaccuracy is measurement hysteresis associated with interactions between the reference vapor, generated by a custom dew point generator, and the sample tubing. Nevertheless, prediction errors associated with correcting the concentration dependence are small compared to total measurement uncertainty. At both sites, changes in measurement repeatability that are not predicted by long-term linear drift estimates are a larger source of error, highlighting the importance of measuring isotopic standards with minimal or well characterized drift at regular intervals. Challenges in monitoring isotopic drift are discussed in light of the different calibration systems evaluated.

AB Pops are a low-frequency, pulsed vocalization produced by Indo-Pacific bottlenose dolphins (Tursiops cf. aduncus) in Shark Bay, Western Australia and are often heard when male alliances are consorting or 'herding' a female. Previous research indicated that pops produced in this context are an agonistic 'come-hither' demand produced by males and directed at female consorts. Here we examine pop occurrence during focal follows on bottlenose dolphin alliances with and without female consorts present. Regression analysis was conducted to determine if pop numbers were higher in the presence of female consorts, and if variables including group size alone and the interaction between presence/absence of a consortship and group size, influenced pop production. While the presence or absence of a consortship significantly affected the number of pops, average group size had no significant effect on pop production. Our research provides further evidence that the pop vocalization plays an important role in consortships.

AB Striking spatial patterns in stable isotope ratios (isoscapes) and elemental ratios (stoichioscapes) of seagrass leaves and the water column nutrients indicate general Plimitation of both water column and benthic primary productivity on the Bermuda Platform, and they highlight the role of the Bermuda Islands as a source of N and P. We found consistent differences among the four seagrass species (Syringodium filiforme, Thalassia testudinum, Halodule sp. and Halophila decipiens) in the N, P, delta C-13 and delta N-15 of leaf tissues. The delta N-15 of seagrass leaves was especially variable, with values from 10.1 to 8.8 parts per thousand. greatly expanding the reported range of values for all seagrass species globally. Spatial patterns from both the water column and the seagrass leaves indicated that P availability was higher near shore, and delta N-15 values suggest this was likely a result of human waste disposal. Spatially contiguous areas of extremely depleted seagrass N-15 suggest unique N sources and cycling compared to other seagrass-dominated environments. Seagrass N: P values were not as far from the stoichiometric balance between N and P availability as in the water column, and there were no strong relationships between the water column N: P and the seagrass N: P. Such isoscapes and stoichioscapes provide valuable ecogeochemical tools to infer ecosystem processes as well as provide information that can inform food web and animal movement studies.

AB Given a most believed value for a quantity together with upper and lower possible deviations from that value, a rectangular distribution might be used to represent state-of-knowledge about the quantity. If the deviations are themselves known by probability distributions, and the value conditioned on the deviations is rectangular, then the marginal distribution of the value is determined by the distributions of the deviations. Here we show under quite general conditions that conversely, given the marginal distribution, the distributions of the deviations are uniquely determined. The case in which the marginal distribution is trapezoidal is studied in some detail.

DESCRIPTION
AB A parameterization for secondary organic aerosol (SOA) production based on the volatility basis set (VBS) approach has been coupled with microphysics and radiative schemes in the Weather Research and Forecasting model with Chemistry (WRF-Chem) model. The new chemistry option called "RACM-MADE-VBS-AQCHEM" was evaluated on a cloud resolving scale against ground-based and aircraft measurements collected during the IMPACT-EUCAARI (Intensive Cloud Aerosol Measurement Campaign - European Integrated project on Aerosol Cloud Climate and Air quality interaction) campaign, and complemented with satellite data from MODIS. The day-to-day variability and the diurnal cycle of ozone (O-3) and nitrogen oxides (NOx) at the surface are captured by the model. Surface aerosol mass concentrations of sulfate (SO4), nitrate (NO3), ammonium (NH4), and organic matter (OM) are simulated with correlations larger than 0.55. WRF-Chem captures the vertical profile of the aerosol mass concentration in both the planetary boundary layer (PBL) and free troposphere (FT) as a function of the synoptic condition, but the model does not capture the full range of the measured concentrations. Predicted OM concentration is at the lower end of the observed mass concentrations. The bias may be attributable to the missing aqueous chemistry processes of organic compounds and to uncertainties in meteorological fields. A key role could be played by assumptions on the VBS approach such as the SOA formation pathways, oxidation rate, and dry deposition velocity of organic condensable vapours. Another source of error in simulating SOA is the uncertainties in the anthropogenic emissions of primary organic carbon. Aerosol particle number concentration (condensation nuclei, CN) is overestimated by a factor of 1.4 and 1.7 within the PBL and FT, respectively. Model bias is most likely attributable to the uncertainties of primary particle emissions (mostly in the PBL) and to the nucleation rate. Simulated cloud condensation nuclei (CCN) are also overestimated, but the bias is more contained with respect to that of CN. The CCN efficiency, which is a characterization of the ability of aerosol particles to nucleate cloud droplets, is underestimated by a factor of 1.5 and 3.8 in the PBL and FT, respectively. The comparison with MODIS data shows that the model overestimates the aerosol optical thickness (AOT). The domain averages (for 1 day) are 0.38 +/- 0.12 and 0.42 +/- 0.10 for MODIS and WRF-Chem data, respectively. The droplet effective radius (Re) in liquid-phase clouds is underestimated by a factor of 1.5; the cloud liquid water path (LWP) is overestimated by a factor of 1.1-1.6. The consequence is the overestimation of average liquid cloud optical thickness (COT) from a few percent up to 42 %. The predicted cloud water path (CWP) in all phases displays a bias in the range +41-80 %, whereas the bias of COT is about 15 %. In sensitivity tests where we excluded SOA, the skills of the model in reproducing the observed patterns and average values of the microphysical and optical properties of liquid and all phase clouds decreases. Moreover, the run without SOA (NOSOA) shows convective clouds with an enhanced content of liquid and frozen hydrometers, and stronger updrafts and downdrafts.
Considering that the previous version of WRF-Chem coupled with a modal aerosol module predicted very low SOA content (secondary organic aerosol model (SORGAM) mechanism) the new proposed option may lead to a better characterization of aerosol-cloud feedbacks.

AB Graphics processing units (GPUs) are an attractive solution in many scientific applications due to their high performance. However, most existing GPU conversions of climate models use GPUs for only a few computationally intensive regions. In the present study, we redesign the mpiPOM (a parallel version of the Princeton Ocean Model) with GPUs. Specifically, we first convert the model from its original Fortran form to a new Compute Unified Device Architecture C (CUDA-C) code, then we optimize the code on each of the GPUs, the communications between the GPUs, and the I / O between the GPUs and the central processing units (CPUs). We show that the performance of the new model on a workstation containing four GPUs is comparable to that on a powerful cluster with 408 standard CPU cores, and it reduces the energy consumption by a factor of 6.8.

AB A regional air-quality forecast system's model of surface ozone variability based on cloud coverage is evaluated using satellite-observed cloud fraction (CF) information and a surface air-quality monitoring system. We compared CF and daily maximum ozone from the National Oceanic and Atmospheric Administration's National Air Quality Forecast Capability (NOAA NAQFC) with CFs from the Moderate Resolution Imaging Spectroradiometer (MODIS) and the US Environmental Protection Agency's AirNow surface ozone measurements during May to October 2014. We found that observed surface ozone shows a negative correlation with the MODIS CFs, showing around 1 ppb decrease for 10% MODIS CF change over the contiguous United States, while the correlation of modeled surface ozone with the model CFs is much weaker, showing only -0.5 ppb per 10% NAQFC CF change. Further, daytime CF differences between MODIS and NAQFC are correlated with modeled surface-ozone biases between AirNow and NAQFC, showing -1.05 ppb per 10% CF change, implying that spatial and temporal misplacement of the modeled cloud field might have biased modeled surface ozone level. Current NAQFC cloud fields seem to have fewer CFs compared to MODIS cloud fields (mean NAQFC CF = 0.38 and mean MODIS CF = 0.55), contributing up to 35% of surface-ozone bias in the current NAQFC system.

AB We describe a new 4D-Var inversion framework for nitrous oxide (N2O) based on the GEOS-Chem chemical transport model and its adjoint, and apply it in a series of observing system simulation experiments to assess how well N2O sources and sinks can be constrained by the current global observing network. The employed measurement ensemble includes approximately weekly and quasicontinuous N2O measurements (hourly averages used) from several long-term monitoring networks, N2O measurements collected from discrete air samples onboard a commercial aircraft (Civil Aircraft for the Regular Investigation of the atmosphere Based on an Instrument Container; CARIBIC), and quasi-continuous measurements from the airborne HIAPER Pole-to-Pole Observations (HIPPO) campaigns. For a 2-year inversion, we find that the surface and HIPPO observations can accurately resolve a uniform bias in emissions during the first year; CARIBIC data provide a somewhat weaker constraint. Variable emission errors are much more difficult to resolve given the long lifetime of N2O, and major parts of the world lack significant constraints on the seasonal cycle of fluxes. Current observations can largely correct a global bias in the stratospheric sink of N2O if emissions are known, but do not provide information on the temporal and spatial distribution of the sink. However, for the more realistic scenario where source and sink are both uncertain, we find that simultaneously optimizing both would require unrealistically small errors in model transport. Regardless, a bias in the magnitude of the N2O sink would not affect the a posteriori N2O emissions for the 2-year timescale used here, given realistic initial conditions, due to the timescale required for stratosphere-troposphere exchange (STE). The same does not apply to model errors in the rate of STE itself, which we show exerts a larger influence on the tropospheric burden of N2O than does the chemical loss rate over short (< 3 year) timescales. We use a stochastic estimate of the inverse Hessian for the inversion to evaluate the spatial resolution of emission constraints provided by the observations, and find that significant, spatially explicit constraints can be achieved in locations near and immediately upwind of surface measurements and the HIPPO flight tracks; however, these are mostly confined to North America, Europe, and Australia. None of the current observing networks are able to provide significant spatial information on tropical N2O emissions. There, averaging kernels (describing the sensitivity of the inversion to emissions in each grid square) are highly smeared spatially and extend even to the midlatitudes, so that tropical emissions risk being conflated with those elsewhere. For global inversions, therefore, the current lack of constraints on the tropics also places an important limit on our ability to understand extratropical emissions. Based on the error reduction statistics from the inverse Hessian, we characterize the atmospheric distribution of unconstrained N2O, and identify regions in and downwind of South America, central Africa, and Southeast Asia where new surface or profile measurements would have the most value for reducing present uncertainty in the global N2O budget.

AB We present a suite of new climate model experiment designs for the Geoengineering Model Intercomparison Project (GeoMIP). This set of experiments, named GeoMIP6 (to be consistent with the Coupled Model Intercomparison Project Phase 6), builds on the previous GeoMIP project simulations, and has been expanded to address several further important topics, including key uncertainties in extreme events, the use of geoengineering as part of a portfolio of responses to climate change, and the relatively new idea of cirrus cloud thinning to allow more longwave radiation to escape to space. We discuss experiment designs, as well as the rationale for those designs, showing preliminary results from individual models when available. We also introduce a new feature, called the GeoMIP Testbed, which provides a platform for simulations that will be performed with a few models and subsequently assessed to determine whether the proposed experiment designs will be adopted as core (Tier 1) GeoMIP experiments. This is meant to encourage various stakeholders to propose new targeted experiments that address their key open science questions, with the goal of making GeoMIP more relevant to a broader set of communities.

AB Binder free (BF) graphite electrodes were utilized to investigate the effect of electrolyte additives fluoroethylene carbonate (FEC) and vinylene carbonate (VC) on the structure of the solid electrolyte interface (SET). The structure of the SET has been investigated via ex-situ surface analysis including X-ray Photoelectron spectroscopy (XPS), Hard XPS (HAXPES), Infrared spectroscopy (IR) and transmission electron microscopy (TEM). The components of the SET have been further investigated via nuclear magnetic resonance (NMR) spectroscopy of D2O extractions. The SET generated on the BF-graphite anode with a standard electrolyte (1.2 M LiPF6 in ethylene carbonate (EC) / ethyl methyl carbonate (EMC), 3/7 (v/v)) is composed primarily of lithium alkyl carbonates (LAC) and LiF. Incorporation of VC (3% wt) results in the generation of a thinner SET composed of Li2CO3, poly(VC), LAC, and LiF. Incorporation of VC inhibits the generation of LAC and LiF. Incorporation of FEC (3% wt) also results in the generation of a thinner SEI composed of Li2CO3, poly(FEC), LAC, and LiF. The concentration of poly(FEC) is lower than the concentration of poly(VC) and the generation of LAC is inhibited in the presence of FEC. The SEI appears to be a homogeneous film for all electrolytes investigated. The Author(s) 2015. Published by ECS. All rights reserved.

AB Tin (Sn) nanoparticle electrodes have been prepared and battery cycling performance has been investigated with 1.2 M LiPF6 in ethylene carbonate (EC) / diethyl carbonate (DEC) electrolyte (1:1, w/w) with and without added vinylene carbonate (VC) or fluoroethylene carbonate (FEC). Incorporation of either VC or FEC improves the capacity retention of Sn nanoparticle electrodes although incorporation of VC also results in a significant increase in cell impedance. The best electrochemical performance was observed with electrolyte containing 10% of added FEC. In order to develop a better understanding of the role of the electrolyte in capacity retention and solid electrolyte interface (SEI) structure, ex-situ surface analysis has been performed on cycled electrodes with infrared (IR) spectroscopy, X-ray photoelectron spectroscopy (XPS), and Hard XPS (HAXPES). The ex-situ analysis reveals a correlation between electrochemical performance, electrolyte composition, and SET structure. (C) The Author(s) 2015. Published by ECS. All rights reserved.

AB The first measurements of perfiuorinated alkyl acids (PFAAs) in wildlife from the aqueous and terrestrial environment showed their ubiquitous presence. Since tile initial studies in 2001 their presence, distribution, and fate in the environment has broadly been studied. PFOS, perfluorooctane sulfonate, is the dominant and most frequently detected PFAA in wildlife from around the world. Additionally long-chain (greater than eight carbons long) perfluoroalkyl carboxylates (PFCAs) have also been measured in biota, with some of the highest concentrations being measured in wildlife from the Arctic. The majority of temporal studies have shown PFOS concentrations increasing over time; however, more recent observations have started showing a decline in PFOS in some wildlife. Long-chain PFCA (greater than eight carbons) concentrations have shown an increase in recent temporal studies, with PFCA concentrations comparable to those of PFOS measured in the same animals. Many food-web studies have examined bioaccumulation and biomagnification of PFAAs. Most studies have shown biomagnification of PFAAs, with PFOS especially having a higher biomagnification potential compared to the PFCAs. While much work has been done during the 15 years PFAAs have been examined in wildlife, there are still gaps. There has been limited work on wildlife from terrestrial ecosystems. There are also many geographical locations that have very limited studies or lack them altogether. Additional monitoring of the terrestrial enviromnent and the inclusion of new geographical locations are needed to help understand the global distribution of PFAAs in wildlife.

AB With the increasing use of pumping to place concrete, the development and refinement of the industry practice to ensure successful concrete pumping are becoming important needs for the concrete construction industry. To date, research on concrete pumping has been largely limited to a few theses and research papers. The major obstacle to conduct research on concrete pumping is that it requires heavy equipment and large amounts of materials. Thus, developing realistic and simple measurement techniques and prediction tools is a financial and logistical challenge that is out of reach for small research labs and many private companies in the concrete construction industry. Moreover, because concrete pumping involves the flow of a complex fluid under pressure in a pipe, predicting its flow necessitates detailed knowledge of the rheological properties of concrete, which requires new measurement science. This paper summarizes the technical challenges associated with concrete pumping and the development in concrete pumping that have been published in the technical literature and identifies future research needed for the industry to develop best practices for ensuring successful concrete pumping in the field.

AB The use of millimeter wavelength radars for probing precipitation has recently gained interest. However, estimation of precipitation variables is not straightforward due to strong signal attenuation, radar receiver saturation, antenna wet radome effects and natural microphysical variability. Here, an automated algorithm is developed for routinely retrieving rain rates from the profiling Ka-band (35-GHz) ARM (Atmospheric Radiation Measurement) zenith radars (KAZR). A 1-dimensional, simple, steady state microphysical model is used to estimate impacts of microphysical processes and attenuation on the profiles of radar observables at 35-GHz and thus provide criteria for identifying situations when attenuation or microphysical processes dominate KAZR observations. KAZR observations are also screened for signal saturation and wet radome effects. The algorithm is implemented in two steps: high rain rates are retrieved by using the amount of attenuation in rain layers, while low rain rates are retrieved from the reflectivity-rain rate (Z(e)-R) relation. Observations collected by the KAZR, rain gauge, disdrometer and scanning precipitating radars during the DY-NAMO/AMIE field campaign at the Gan Island of the tropical Indian Ocean are used to validate the proposed approach. The differences in the rain accumulation from the proposed algorithm are quantified. The results indicate that the proposed algorithm has a potential for deriving continuous rain rate statistics in the tropics.

AB The Arctic troposphere has warmed faster than the global average over the last several decades. It was suggested that atmospheric northward energy transport (ANET) into the Arctic had contributed to tropospheric warming in the Arctic. Here we calculate ANET based on the NCEP/NCAR reanalysis data from 1979 to 2012. During this period the zonally integrated energy flux into the Arctic has decreased rather than increased in all seasons. However, the trends are statistically insignificant except for the winter and annual mean fluxes. For the winter season, the transient eddy flux of energy increases over Greenland and the Greenland Sea and decreases over west-central Siberia (WCS). Trends in meridional wind variance and vorticity also indicate increasing transient eddy activity over Northern Canada, the Greenland Sea and the Norwegian Sea and decreasing activity over WCS. Inter-winter variations in local vorticity over the WCS are significantly anti-correlated with the Arctic climate.

Deposit morphologies range from specular surfaces to highly faceted dendrite-like grains of moderate aspect ratio and, for potentials within the NDR region, sub-50 nm diameter, high aspect ratio 110 oriented single crystal nanowires. The nanowires exhibit an epitaxial relationship to the substrate that permits one step fabrication of surfaces densely covered with high aspect ratio nanowires having controlled orientations. The NDR and nanowires are a consequence of the non-monotonic relationship between Tl coverage and growth velocity; at low coverage Tl accelerates Au deposition while at higher coverage it inhibits deposition. Immiscibility of the Tl and Au supports on-going surface segregation during area expansion that accompanies nanowire growth leading to greater dilution of the additive coverage and more rapid growth at the nanowire tips, while the sidewalls remain passivated by a saturated Tl coverage.

AB There has been much interest in the dimensional properties of double-stranded DNA (dsDNA) confined to nanoscale environments as a problem of fundamental importance in both biological and technological fields. This has led to a series of measurements by fluorescence microscopy of single dsDNA molecules under confinement to nanofluidic slits. Despite the efforts expended on such experiments and the corresponding theory and simulations of confined polymers, a consistent description of changes of the radius of gyration of dsDNA under strong confinement has not yet emerged. Here, we perform molecular dynamics (MD) simulations to identify relevant factors that might account for this inconsistency. Our simulations indicate a significant amplification of excluded volume interactions under confinement at the nanoscale due to the reduction of the effective dimensionality of the system. Thus, any factor influencing the excluded volume interaction of dsDNA, such as ionic strength, solution chemistry, and even fluorescent labels, can greatly influence the dsDNA size under strong confinement. These factors, which are normally less important in bulk solutions of dsDNA at moderate ionic strengths because of the relative weakness of the excluded volume interaction, must therefore be under tight control to achieve reproducible measurements of dsDNA under conditions of dimensional reduction. By simulating semi-flexible polymers over a range of parameter values relevant to the experimental systems and exploiting past theoretical treatments of the dimensional variation of swelling exponents and prefactors, we have developed a novel predictive relationship for the in-plane radius of gyration of long semi-flexible polymers under slit-like confinement. Importantly, these analytic expressions allow us to estimate the properties of dsDNA for the experimentally and biologically relevant range of contour lengths that is not currently accessible by state-of-the-art MD simulations.

AB Combinatorial testing has rapidly gained favor among software testers in the past decade as improved algorithms have become available and practical success has been demonstrated. This chapter reviews the theory and application of this method, focusing particularly on research since 2010, with a brief background providing the rationale and development of combinatorial methods for software testing. Significant advances have occurred in algorithm performance, and the critical area of constraint representation and processing. In addition to these foundational topics, we take a look at advances in specialized areas including test suite prioritization, sequence testing, fault localization, the relationship between combinatorial testing and structural coverage, and approaches to very large testing problems.

AB Airborne and spaceborne altimeters provide measurements of sea-ice elevation, from which sea-ice freeboard and thickness may be derived. Observations of the Arctic ice pack by satellite altimeters indicate a significant decline in ice thickness, and volume, over the last decade. NASA's Ice, Cloud and land Elevation Satellite-2 (ICESat-2) is a next-generation laser altimeter designed to continue key sea-ice observations through the end of this decade. An airborne simulator for ICESat-2, the Multiple Altimeter Beam Experimental Lidar (MABEL), has been deployed to gather pre-launch data for mission development. We present an analysis of MABEL data gathered over sea ice in the Greenland Sea and assess the capabilities of photon-counting techniques for sea-ice freeboard retrieval. We compare freeboard estimates in the marginal ice zone derived from MABEL photon-counting data with coincident data collected by a conventional airborne laser altimeter. We find that freeboard estimates agree to within 0.03 m in the areas where sea-ice floes were interspersed with wide leads, and to within 0.07 m elsewhere. MABEL data may also be used to infer sea-ice thickness, and when compared with coincident but independent ice thickness estimates, MABEL ice thicknesses agreed to within 0.65 m or better.

AB Quaternary chalcogenides with tetrahedral zinc-blend structure types continue to be of interest for thermoelectrics applications. We report on the synthesis, crystal structure, and high temperature transport properties of Cu2.1Fe0.9SnSe4, Cu2.2Fe0.8SnSe4 and Cu2.2Zn0.2Fe0.6SnSe4. The identity and compositions for each specimen were established using a combination of Rietveld refinement and elemental analysis and indicate that all compositions are homogeneous with the stannite crystal structure. Excess Cu reduces the electrical resistivity, rho, by an order of magnitude compared with Cu2FeSnSe4 with no significant degradation of the Seebeck coefficient, S. The energy band gaps were estimated from the high temperature S values and indicate that Cu2.1Fe0.9SnSe4 and Cu2.2Fe0.8SnSe4 possess narrow band gaps, 0.18 eV and 0.25 eV, respectively, as compared to most other quaternary chalcogenides. The power factor (PF = S-2/rho) increases with decreasing Fe content. Although Cu2.2Fe0.8SnSe4 possesses a smaller PF than that of Cu2.2Zn0.2Fe0.6SnSe4, a ZT of 0.45 was obtained at 750 K for Cu2.2Fe0.8SnSe4 due to its low thermal conductivity.

AB Between April 1925 and June 1927, the research vessel Meteor cruised the tropical and southern Atlantic Ocean in the framework of the German Atlantic Expedition. One purpose was to systematically explore the vertical structure of the atmosphere. To this end, the ocean was crossed in 14 profiles across parallels of latitude. 801 pilot balloons and 217 kites were launched. The resulting data have been digitised in the framework of the European project ERA-CLIM. Here, they are compared to the Twentieth Century (20CR) and ERA-20C reanalyses, independent datasets based on the assimilation of synoptic pressure and hurricane pressure records, and marine surface winds for the latter, using monthly sea surface temperature and sea ice as boundary conditions. Both reanalyses display similar patterns of systematic differences relative to the observations for temperature, specific humidity, and wind. Furthermore, 20CR and ERA-20C show generally comparable anomaly correlations for all parameters, with the highest values found for pressure and temperature. In the southern extratropics, high (> 0.75) anomaly correlations are found for pressure in both 20CR and ERA-20C, and for temperature in 20CR. Medium (> 0.5) anomaly correlations are found for specific humidity in 20CR. Moderate anomaly correlations (> 0.44) are found for meridional wind in both 20CR and ERA-20C, and for temperature in ERA-20C. In contrast, low anomaly correlations (< 0.44) are found for zonal wind both in 20CR and ERA-20C, and for specific humidity in ERA-20C. In the Tropics, low anomaly correlations are found for all parameters except for pressure, which shows medium anomaly correlations for both 20CR and ERA-20C, and for meridional wind, which shows moderate anomaly correlations for 20CR. In all regions, both reanalyses strongly underestimate the observed range of zonal and particularly meridional wind variability. Even though remaining errors in the observational data cannot be excluded, we estimate that the inherent observational uncertainties do not alter our conclusions. Vice versa, two pieces of evidence support the credibility of the early upper-air data: the robust regressions of both 20CR and ERA-20C against observed pressure and temperature over a large spatial and temporal range, and the similarity between the uncertainties predicted by 20CR and the actual uncertainties determined from the root mean square difference of reanalysis and observation values.

AB Volatile organic compound (VOC) species from vehicle exhausts and gas evaporation were investigated by chassis dynamometer and on-road measurements of nine gasoline vehicles, seven diesel vehicles, five motorcycles, and four gas evaporation samples. The secondary organic aerosol (SOA) mass yields of gasoline, diesel, motorcycle exhausts, and gas evaporation were estimated based on the mixing ratio of measured C2-C12 VOC species and inferred carbon number distributions. High aromatic contents were measured in gasoline exhausts and contributed comparatively more SOA yield. A vehicular emission inventory was compiled based on a local survey of on-road traffic in Shanghai and real-world measurements of vehicle emission factors from previous studies in the cities of China. The inventory-based vehicular organic aerosol (OA) productions to total CO emissions were compared with the observed OA to CO concentrations (Delta OA/Delta CO) in the urban atmosphere. The results indicate that vehicles dominate the primary organic aerosol (POA) emissions and OA production, which contributed about 40 and 60% of OA mass in the urban atmosphere of Shanghai. Diesel vehicles, which accounted for less than 20% of vehicle kilometers of travel (VKT), contribute more than 90% of vehicular POA emissions and 80-90% of OA mass derived by vehicles in urban Shanghai. Gasoline exhaust could be an important source of SOA formation. Tightening the limit of aromatic content in gasoline fuel will be helpful to reduce its SOA contribution. Intermediate-volatile organic compounds (IVOCs) in vehicle exhausts greatly contribute to SOA formation in the urban atmosphere of China. However, more experiments need to be conducted to determine the contributions of IVOCs to OA pollution in China.

AB Isoprene hydroxynitrates (IN) are tracers of the photochemical oxidation of isoprene in high NOx environments. Production and loss of IN have a significant influence on the NOx cycle and tropospheric O-3 chemistry. To better understand IN chemistry, a series of photochemical reaction chamber experiments was conducted to determine the IN yield from isoprene photooxidation at high NO concentrations (>100 ppt). By combining experimental data and calculated isomer distributions, a total IN yield of 9(+4/-3)% was derived. The result was applied in a zero-dimensional model to simulate production and loss of ambient IN observed in a temperate forest atmosphere, during the Southern Oxidant and Aerosol Study (SOAS) field campaign, from 27 May to 11 July 2013. The 9% yield was consistent with the observed IN/(MVK+MACR) ratios observed during SOAS. By comparing field observations with model simulations, we identified NO as the limiting factor for ambient IN production during SOAS, but vertical mixing at dawn might also contribute (similar to 27 %) to IN dynamics. A close examination of isoprene's oxidation products indicates that its oxidation transitioned from a high-NO dominant chemical regime in the morning into a low-NO dominant regime in the afternoon. A significant amount of IN produced in the morning high NO regime could be oxidized in the low NO regime, and a possible reaction scheme was proposed.

TI HTAP_v2.2: a mosaic of regional and global emission grid maps for 2008
and 2010 to study hemispheric transport of air pollution
SO ATMOSPHERIC CHEMISTRY AND PHYSICS
LA English
DT Article
ID TRENDS; METHODOLOGY; DIOXIDE; GASES; ASIA
AB The mandate of the Task Force Hemispheric Transport of Air Pollution (TF HTAP) under the Convention on Long-Range Transboundary Air Pollution (CLRTAP) is to improve the scientific understanding of the intercontinental air pollution transport, to quantify impacts on human health, vegetation and climate, to identify emission mitigation options across the regions of the Northern Hemisphere, and to guide future policies on these aspects.
The harmonization and improvement of regional emission inventories is imperative to obtain consolidated estimates on the formation of global-scale air pollution. An emissions data set has been constructed using regional emission grid maps (annual and monthly) for SO2, NOx, CO, NMVOC, NH3, PM10, PM2.5, BC and OC for the years 2008 and 2010, with the purpose of providing consistent information to global and regional scale modelling efforts.
This compilation of different regional gridded inventories - including that of the Environmental Protection Agency (EPA) for USA, the EPA and Environment Canada (for Canada), the European Monitoring and Evaluation Programme (EMEP) and Netherlands Organisation for Applied Scientific Research (TNO) for Europe, and the Model Intercomparison Study for Asia (MICS-Asia III) for China, India and other Asian countries - was gap-filled with the emission grid maps of the Emissions Database for Global Atmospheric Research (EDGARv4.3) for the rest of the world (mainly South America, Africa, Russia and Oceania). Emissions from seven main categories of human activities (power, industry, residential, agriculture, ground transport, aviation and shipping) were estimated and spatially distributed on a common grid of 0.1 degrees x 0.1 degrees longitude-latitude, to yield monthly, global, sector-specific grid maps for each substance and year.
The HTAP_v2.2 air pollutant grid maps are considered to combine latest available regional information within a complete global data set. The disaggregation by sectors, high spatial and temporal resolution and detailed information on the data sources and references used will provide the user the required transparency. Because HTAP_v2.2 contains primarily official and/or widely used regional emission grid maps, it can be recommended as a global baseline emission inventory, which is regionally accepted as a reference and from which different scenarios assessing emission reduction policies at a global scale could start.
An analysis of country-specific implied emission factors shows a large difference between industrialised countries and developing countries for acidifying gaseous air pollutant emissions (SO2 and NOx) from the energy and industry sectors. This is not observed for the particulate matter emissions (PM10, PM2.5), which show large differences between countries in the residential sector instead. The per capita emissions of all world countries, classified from low to high income, reveal an increase in level and in variation for gaseous acidifying pollutants, but not for aerosols. For aerosols, an opposite trend is apparent with higher per capita emissions of particulate matter for low income countries.

AB Assessing the impacts of anthropogenic ocean acidification requires knowledge of present-day and future environmental conditions. Here, we present a simple model for upwelling margins that projects anthropogenic acidification trajectories by combining high-temporal-resolution sensor data, hydrographic surveys for source water characterization, empirical relationships of the CO2 system, and the atmospheric CO2 record. This model characterizes CO2 variability on timescales ranging from hours (e. g., tidal) to months (e. g., seasonal), bridging a critical knowledge gap in ocean acidification research. The amount of anthropogenic carbon in a given water mass is dependent on the age; therefore a density-age relationship was derived for the study region and then combined with the 2013 Intergovernmental Panel on Climate Change CO2 emission scenarios to add density-dependent anthropogenic carbon to the sensor time series. The model was applied to time series from autonomous pH sensors deployed in the surf zone, kelp forest, submarine canyon edge, and shelf break in the upper 100m of the Southern California Bight. All habitats were within 5 km of one another, and exhibited unique, habitat-specific CO2 variability signatures and acidification trajectories, demonstrating the importance of making projections in the context of habitat-specific CO2 signatures. In general, both the mean and range of pCO(2) increase in the future, with the greatest increase in both magnitude and range occurring in the deeper habitats due to reduced buffering capacity. On the other hand, the saturation state of aragonite (Omega(Ar)) decreased in both magnitude and range. This approach can be applied to the entire California Current System, and upwelling margins in general, where sensor and complementary hydrographic data are available.

AB C-C coupling reactions are of great importance in the synthesis of numerous organic compounds, where Pd nanoparticle catalyzed systems represent new materials to efficiently drive these reactions. Despite their pervasive utility, the catalytic mechanism of these particle-based reactions remains highly contested. Herein we present evidence of an atom leaching mechanism for Stille coupling under aqueous conditions using peptide-capped Pd nanoparticles. EXAFS analysis revealed Pd coordination changes in the nanoparticle consistent with Pd atom abstraction, where sizing analysis by SAXS confirmed particle size changes associated with a leaching process. It is likely that recently discovered highly disordered surface Pd atoms are the favored catalytic active sites and are leached during oxidative addition, resulting in smaller particles. Probing the mechanism of nanoparticle-driven C-C coupling reactions through structural analyses provides fundamental information concerning these active sites and their reactivity at the atomic-scale, which can be used to improve catalytic performance to meet important sustainability goals.

AB We employed an optimal interpolation (OI) method to assimilate AIRNow ozone/PM2.5 and MODIS (Moderate Resolution Imaging Spectroradiometer) aerosol optical depth (AOD) data into the Community Multi-scale Air Quality (CMAQ) model to improve the ozone and total aerosol concentration for the CMAQ simulation over the contiguous United States (CONUS). AIRNow data assimilation was applied to the boundary layer, and MODIS AOD data were used to adjust total column aerosol. Four OI cases were designed to examine the effects of uncertainty setting and assimilation time; two of these cases used uncertainties that varied in time and location, or dynamic uncertainties. More frequent assimilation and higher model uncertainties pushed the modeled results closer to the observation. Our comparison over a 24-hr period showed that ozone and PM2.5 mean biases could be reduced from 2.54 ppbV to 1.06 ppbV and from -7.14 mu g/m(3) to -0.11 mu g/m(3), respectively, over CONUS, while their correlations were also improved. Comparison to DISCOVER-AQ 2011 aircraft measurement showed that surface ozone assimilation applied to the CMAQ simulation improves regional low-altitude (below 2 km) ozone simulation.Implications: This paper described an application of using optimal interpolation method to improve the model's ozone and PM2.5 estimation using surface measurement and satellite AOD. It highlights the usage of the operational AIRNow data set, which is available in near real time, and the MODIS AOD. With a similar method, we can also use other satellite products, such as the latest VIIRS products, to improve PM2.5 prediction.

AB Fires in the open or in large enclosures are characterized as localized fires, e.g., vehicle fires in transportation infrastructures, small shop fires in transport terminal halls, and workstation fires in open plan office buildings. Compartment fires start from localized burning. The current structural fire design approaches are developed for fully-developed compartment fires, the gas temperatures of which can be approximated as uniformly distributed in the compartment. In localized fires, the gas temperature distributions are spatially non-uniform. There is lack of knowledge about the behavior of structures subjected to localized fires. Design guides and engineering approaches are needed for structural safety design in localized fires.
This paper discusses the application of localized fires for structural safety design. Some recent studies on the thermal calculation and structural analysis of steel members subjected to localized fires were presented. Simple fire models were provided to calculate the temperature of exposed steel members in a localized fire. Thermo-mechanical simulations were performed to investigate the failure mode of bare steel members in a localized fire. The studies found that due to thermal gradient, a bare steel member may fail in a totally different way in a localized fire than in a standard fire; and the failure temperature for a bare steel member in a localized fire might be hundreds of degree lower than that in a standard fire. Using the proposed simple models, an engineering approach was also provided to determine the safety distance from a bare steel column to a fire source, which could be used in a performance-based fire safety design.

AB Accurate estimates of the emissions and distribution of black carbon (BC) in the region referred to here as Southeastern Asia (70-150A degrees E, 11A degrees S-55A degrees N) are critical to studies of the atmospheric environment and climate change. Analysis of modeled BC concentrations compared to in situ observations indicates levels are underestimated over most of Southeast Asia when using any of four different emission inventories. We thus attempt to reduce uncertainties in BC emissions and improve BC model simulations by developing top-down, spatially resolved, estimates of BC emissions through assimilation of OMI (Ozone Monitoring Instrument) observations of aerosol absorption optical depth (AAOD) with the GEOS-Chem (Goddard Earth Observing System - chemistry) model and its adjoint for April and October 2006. Overwhelming enhancements, up to 500 %, in anthropogenic BC emissions are shown after optimization over broad areas of Southeast Asia in April. In October, the optimization of anthropogenic emissions yields a slight reduction (1-5 %) over India and parts of southern China, while emissions increase by 10-50 % over eastern China. Observational data from in situ measurements and AERONET (Aerosol Robotic Network) observations are used to evaluate the BC inversions and assess the bias between OMI and AERONET AAOD. Low biases in BC concentrations are improved or corrected in most eastern and central sites over China after optimization, while the constrained model still underestimates concentrations in Indian sites in both April and October, possibly as a consequence of low prior emissions. Model resolution errors may contribute up to a factor of 2.5 to the underestimation of surface BC concentrations over northern India. We also compare the optimized results using different anthropogenic emission inventories and discuss the sensitivity of top-down constraints on anthropogenic emissions with respect to biomass burning emissions. In addition, the impacts of brown carbon, the formulation of the observation operator, and different a priori constraints on the optimization are investigated. Overall, despite these limitations and uncertainties, using OMI AAOD to constrain BC sources improves model representation of BC distributions, particularly over China.

AB We use an ensemble of surface (EPA CSN, IMPROVE, SEARCH, AERONET), aircraft (SEAC(4)RS), and satellite (MODIS, MISR) observations over the southeast US during the summer-fall of 2013 to better understand aerosol sources in the region and the relationship between surface particulate matter (PM) and aerosol optical depth (AOD). The GEOS-Chem global chemical transport model (CTM) with 25 x 25 km(2) resolution over North America is used as a common platform to interpret measurements of different aerosol variables made at different times and locations. Sulfate and organic aerosol (OA) are the main contributors to surface PM2.5 (mass concentration of PM finer than 2.5 mu m aerodynamic diameter) and AOD over the southeast US. OA is simulated successfully with a simple parameterization, assuming irreversible uptake of low-volatility products of hydrocarbon oxidation. Biogenic isoprene and monoterpenes account for 60 % of OA, anthropogenic sources for 30 %, and open fires for 10 %. 60 % of total aerosol mass is in the mixed layer below 1.5 km, 25 % in the cloud convective layer at 1.5-3 km, and 15 % in the free troposphere above 3 km. This vertical profile is well captured by GEOS-Chem, arguing against a high-altitude source of OA. The extent of sulfate neutralization (f = [NH4+]/(2[SO42-] + [NO3-]) is only 0.5-0.7 mol mol(-1) in the observations, despite an excess of ammonia present, which could reflect suppression of ammonia uptake by OA. This would explain the long-term decline of ammonium aerosol in the southeast US, paralleling that of sulfate. The vertical profile of aerosol extinction over the southeast US follows closely that of aerosol mass. GEOS-Chem reproduces observed total column aerosol mass over the southeast US within 6 %, column aerosol extinction within 16 %, and space-based AOD within 8-28 % (consistently biased low). The large AOD decline observed from summer to winter is driven by sharp declines in both sulfate and OA from August to October. These declines are due to shutdowns in both biogenic emissions and UV-driven photochemistry. Surface PM2.5 shows far less summer-to-winter decrease than AOD and we attribute this in part to the offsetting effect of weaker boundary layer ventilation. The SEAC4RS aircraft data demonstrate that AODs measured from space are consistent with surface PM2.5. This implies that satellites can be used reliably to infer surface PM2.5 over monthly timescales if a good CTM representation of the aerosol vertical profile is available.

AB We test the current generation of global chemistry-climate models in their ability to simulate observed, present-day surface ozone. Models are evaluated against hourly surface ozone from 4217 stations in North America and Europe that are averaged over 1A degrees x 1A degrees grid cells, allowing commensurate model-measurement comparison. Models are generally biased high during all hours of the day and in all regions. Most models simulate the shape of regional summertime diurnal and annual cycles well, correctly matching the timing of hourly (similar to 15:00 local time (LT)) and monthly (mid-June) peak surface ozone abundance. The amplitude of these cycles is less successfully matched. The observed summertime diurnal range (similar to 25 ppb) is underestimated in all regions by about 7 ppb, and the observed seasonal range (similar to 21 ppb) is underestimated by about 5 ppb except in the most polluted regions, where it is overestimated by about 5 ppb. The models generally match the pattern of the observed summertime ozone enhancement, but they overestimate its magnitude in most regions. Most models capture the observed distribution of extreme episode sizes, correctly showing that about 80 % of individual extreme events occur in large-scale, multi-day episodes of more than 100 grid cells. The models also match the observed linear relationship between episode size and a measure of episode intensity, which shows increases in ozone abundance by up to 6 ppb for larger-sized episodes. We conclude that the skill of the models evaluated here provides confidence in their projections of future surface ozone.

AB This study investigates the maintenance of cloud ice production in Arctic mixed-phase stratocumulus in large eddy simulations that include a prognostic ice nuclei (IN) formulation and a diurnal cycle. Balances derived from a mixed-layer model and phase analyses are used to provide insight into buffering mechanisms that maintain ice in these cloud systems. We find that, for the case under investigation, IN recycling through subcloud sublimation considerably prolongs ice production over a multi-day integration. This effective source of IN to the cloud dominates over mixing sources from above or below the cloud-driven mixed layer. Competing feedbacks between dynamical mixing and recycling are found to slow the rate of ice lost from the mixed layer when a diurnal cycle is simulated. The results of this study have important implications for maintaining phase partitioning of cloud ice and liquid that determine the radiative forcing of Arctic mixed-phase clouds.

AB Arctic boundary layer nitrogen oxides (NOx = NO2 + NO) are naturally produced in and released from the sunlit snowpack and range between 10 to 100 pptv in the remote background surface layer air. These nitrogen oxides have significant effects on the partitioning and cycling of reactive radicals such as halogens and HOx (OH + HO2). However, little is known about the impacts of local anthropogenic NOx emission sources on gas-phase halogen chemistry in the Arctic, and this is important because these emissions can induce large variability in ambient NOx and thus local chemistry. In this study, a zero-dimensional photochemical kinetics model was used to investigate the influence of NOx on the unique springtime halogen and HOx chemistry in the Arctic. Trace gas measurements obtained during the 2009 OASIS (Ocean - Atmosphere - Sea Ice - Snowpack) field campaign at Barrow, AK were used to constrain many model inputs. We find that elevated NOx significantly impedes gas-phase halogen radical-based depletion of ozone, through the production of a variety of reservoir species, including HNO3, HO2NO2, peroxyacetyl nitrate (PAN), BrNO2, ClNO2 and reductions in BrO and HOBr. The effective removal of BrO by anthropogenic NOx was directly observed from measurements conducted near Prudhoe Bay, AK during the 2012 Bromine, Ozone, and Mercury Experiment (BROMEX). Thus, while changes in snow-covered sea ice attributable to climate change may alter the availability of molecular halogens for ozone and Hg depletion, predicting the impact of climate change on polar atmospheric chemistry is complex and must take into account the simultaneous impact of changes in the distribution and intensity of anthropogenic combustion sources. This is especially true for the Arctic, where NOx emissions are expected to increase because of increasing oil and gas extraction and shipping activities.

AB Rapid Asian industrialization has led to increased downwind atmospheric nitrogen deposition threatening the marine environment. We present an analysis of the sources and processes controlling atmospheric nitrogen deposition to the northwestern Pacific, using the GEOS-Chem global chemistry model and its adjoint model at 1/2A degrees x 2/3A degrees horizontal resolution over East Asia and its adjacent oceans. We focus our analyses on the marginal seas: the Yellow Sea and the South China Sea. Asian nitrogen emissions in the model are 28.6 Tg N a(-1) as NH3 and 15.7 Tg N a(-1) as NOx. China has the largest sources with 12.8 Tg N a(-1) as NH3 and 7.9 Tg N a(-1) as NOx; the high-NH3 emissions reflect its intensive agricultural activities. We find Asian NH3 emissions are a factor of 3 higher in summer than winter. The model simulation for 2008-2010 is evaluated with NH3 and NO2 column observations from satellite instruments, and wet deposition flux measurements from surface monitoring sites. Simulated atmospheric nitrogen deposition to the northwestern Pacific ranges 0.8-20 kg N ha(-1) a(-1), decreasing rapidly downwind of the Asian continent. Deposition fluxes average 11.9 kg N ha(-1) a(-1) (5.0 as reduced nitrogen NHx and 6.9 as oxidized nitrogen NOy) to the Yellow Sea, and 5.6 kg N ha(-1) a(-1) (2.5 as NHx and 3.1 as NOy) to the South China Sea. Nitrogen sources over the ocean (ship NOx and oceanic NH3) have little contribution to deposition over the Yellow Sea, about 7 % over the South China Sea, and become important (greater than 30 %) further downwind. We find that the seasonality of nitrogen deposition to the northwestern Pacific is determined by variations in meteorology largely controlled by the East Asian monsoon and in nitrogen emissions. The model adjoint further estimates that nitrogen deposition to the Yellow Sea originates from sources over China (92 % contribution) and the Korean peninsula (7 %), and by sectors from fertilizer use (24 %), power plants (22 %), and transportation (18 %). Deposition to the South China Sea shows source contribution from mainland China (66 %), Taiwan (20 %), and the rest (14 %) from the southeast Asian countries and oceanic NH3 emissions. The adjoint analyses also indicate that reducing Asian NH3 emissions would increase NOy dry deposition to the Yellow Sea (28 % offset annually), limiting the effectiveness of NH3 emission controls on reducing nitrogen deposition to the Yellow Sea.

AB Materials and photoelectrode architectures that are highly efficient, extremely stable, and made from low cost materials are required for commercially viable photoelectrochemical (PEC) water-splitting technology. A key challenge is the heterogeneous nature of real-world materials, which often possess spatial variation in their crystal structure, morphology, and/or composition at the nano-, micro-, or macro-scale. Different structures and compositions can have vastly different properties and can therefore strongly influence the overall performance of the photoelectrode through complex structure-property relationships. A complete understanding of photoelectrode materials would also involve elucidation of processes such as carrier collection and electrochemical charge transfer that occur at very fast time scales. We present herein an overview of a broad suite of experimental and computational tools that can be used to define the structure-property relationships of photoelectrode materials at small dimensions and on fast time scales. A major focus is on in situ scanning-probe measurement (SPM) techniques that possess the ability to measure differences in optical, electronic, catalytic, and physical properties with nano- or micro-scale spatial resolution. In situ ultrafast spectroscopic techniques, used to probe carrier dynamics involved with processes such as carrier generation, recombination, and interfacial charge transport, are also discussed. Complementing all of these experimental techniques are computational atomistic modeling tools, which can be invaluable for interpreting experimental results, aiding in materials discovery, and interrogating PEC processes at length and time scales not currently accessible by experiment. In addition to reviewing the basic capabilities of these experimental and computational techniques, we highlight key opportunities and limitations of applying these tools for the development of PEC materials.

AB Decreased marine survival is identified as a component driver of continued declines of Atlantic Salmon Salmo salar. However, estimates of marine mortality often incorporate loss incurred during estuary migration that may be mechanistically distinct from factors affecting marine mortality. We examined movements and survival of 941 smolts (141 wild and 800 hatchery-reared fish) released in freshwater during passage through the Penobscot River estuary, Maine, from 2005 to 2013. We related trends in estuary arrival date, movement rate, and survival to fish characteristics, migratory history, and environmental conditions in the estuary. Fish that experienced the warmest thermal history arrived in the estuary 8 d earlier than those experiencing the coolest thermal history during development. Estuary arrival date was 10 d later for fish experiencing high flow than for fish experiencing low flow. Fish released furthest upstream arrived in the estuary 3 d later than those stocked further downstream but moved 0.5 km/h faster through the estuary. Temporally, movement rate and survival in the estuary both peaked in mid-May. Spatially, movement rate and survival both decreased from freshwater to the ocean. Wild smolts arrived in the estuary later than hatchery fish, but we observed no change in movement rate or survival attributable to rearing history. Fish with the highest gill Na+, K+-ATPase activity incurred 25% lower mortality through the estuary than fish with the lowest gill Na+, K+-ATPase activity. Smolt survival decreased (by up to 40%) with the increasing number of dams passed (ranging from two to nine) during freshwater migration. These results underscore the importance of physiological preparedness on performance and the delayed, indirect effects of dams on survival of Atlantic Salmon smolts during estuary migration, ultimately affecting marine survival estimates.

TI Spatial and Temporal Patterns in Smolt Survival of Wild and Hatchery

AB Understanding the factors contributing to declining smolt-to-adult survival (hereafter "smolt survival") of Coho Salmon Oncorhynchus kisutch originating in the Salish Sea of southwestern British Columbia and Washington State is a high priority for fish management agencies. Uncertainty regarding the relative importance of mortality operating at different spatial scales hinders the prioritization of science and management activities. We therefore examined spatial and temporal coherence in smolt survivals for Coho Salmon based on a decision tree framework organized by spatial hierarchy. Smolt survival patterns of populations that entered marine waters within the Salish Sea were analyzed and compared with Pacific coast reference populations at similar latitudes. In all areas, wild Coho Salmon had higher survival than hatchery Coho Salmon. Coherence in Coho Salmon smolt survival occurred at multiple spatial scales during ocean entry years 1977-2010. The primary pattern within the Salish Sea was a declining smolt survival trend over this period. In comparison, smolt survival of Pacific coast reference populations was low in the 1990s but subsequently increased. Within the Salish Sea, smolt survival in the Strait of Georgia declined faster than it did in Puget Sound. Spatial synchrony was stronger among neighboring Salish Sea populations and occurred at a broader spatial scale immediately following the 1989 ecosystem regime shift in the North Pacific Ocean than before or after. Smolt survival of Coho Salmon was synchronized at a more local scale than reported by other researchers for Chinook Salmon O. tshawytscha, Pink Salmon O. gorbuscha, Chum Salmon O. keta, and Sockeye Salmon O. nerka, suggesting that early marine conditions are especially important for Coho Salmon in the Salish Sea. Further exploration of ecosystem variables at multiple spatial scales is needed to effectively address linkages between the marine ecosystem and Coho Salmon smolt survival within the Salish Sea. Since the relative importance of particular variables may have changed during our period of record, researchers will need to carefully match spatial and temporal scales to their questions of interest.

AB The pink shrimp Farfantepenaeus duorarum, one of the commercially important Penaeidae, reproduces offshore of the southwest Florida (SWF) shelf. Larvae migrate to nursery grounds in estuarine Florida Bay. Using a numerical approach, we investigated the role of spawning location, larval traits, and physical forces on the transport of pink shrimp larvae. First, the Regional Oceanic Modeling System that is based on tides, air-ocean fluxes, and freshwater flows was used to simulate the SWF shelf oceanography. The model replicates the tides, winds, salinity, currents, and seasonality of the shelf. Secondly, the Regional Oceanic Modeling System was coupled offline with the Connectivity Modeling System, in which virtual larvae were released near the surface from two spawning sites, Dry Tortugas and Marquesas, and tracked until the time for settlement (about 28-30 d). Virtual larvae moved vertically in the water column following ontogenetic behaviors previously observed in the field: diel vertical migration (DVM) and selective tidal stream transport (STST). Lagrangian trajectories indicated that migration paths changed radically between summer and winter during model years (1995-1997). Maximum settlements occurred in summer by larvae crossing the SWF shelf, while the lowest settlement occurred in winter by larvae moving through passes in the Florida Keys. Modeling results demonstrated an effective east-northeast transport across the SWF shelf during summer as a result of the tidal currents, the subtidal currents, and the combined DVM and STST behaviors. The current phase captured during the initial DVM period was critical to determine the direction in which larvae move, favorable (east and northward) or unfavorable (south and westward), before the STST behavior captures the eastward tidal current that brings larvae to the nursery grounds. Unfavorable currents were driven by the summer easterlies and low salinities at the coast. Results indicated that Marquesas is the more effective spawning ground, with 4.5 times more likely settlement of originating larvae compared with Dry Tortugas. Model-estimated seasonal settlement patterns concurred with postlarval influxes previously observed at Florida Bay boundaries.

TI Effects of Slotted Water Control Structures on Nekton Movement within
Salt Marshes
SO MARINE AND COASTAL FISHERIES

ID IDENTIFICATION SONAR DIDSON; FISH PASSAGE; COASTAL FISHES; RIVER;
MANAGEMENT; ESTUARINE; BEHAVIOR; PERFORMANCE; UPSTREAM; HABITAT
AB Water control structures (WCSs) restrict hydrological connectivity in salt marshes and thereby impede nekton movement within the greater habitat mosaic. Transient fishery species, which spawn outside salt marshes and must get past these barriers to reach spawning areas or salt-marsh nurseries, are especially vulnerable to these structures. Water control structures incorporating slots (narrow vertical openings spanning most of the water column) are thought to improve nekton passage; however, few studies have directly examined nekton passage through WCS slots. Dual-frequency identification sonar (DIDSON) acoustic imaging was used monthly (April-September 2010) on diurnal flood tides to examine nekton movement through 15-cm-wide slots at two identical WCSs located in Louisiana tidal marsh channels. Nekton behavior was compared between these WCSs and a nearby natural salt-marsh creek. Examination of 12 h of subsampled acoustic data revealed large concentrations of salt-marsh nekton at the WCSs (n = 2,970 individuals total), but passage rates through the slots were low (<= 10% of total observed individuals migrated via the slots). Most migrating fish were observed leaving the managed area and swimming against a flood tide. The mean size of migrating individuals (similar to 25 cm TL) did not differ in relation to swimming direction (going into versus exiting the managed marsh) and was similar to that reported from other studies examining similar slot widths. Nekton formed congregations in the WCS channel, but no congregations were observed in the natural salt-marsh creek, even though nekton species composition and sizes were similar among sites. The WCSs in our study appear to function as ecological hot spots, where large individuals may encounter enhanced foraging opportunities but also fishing mortality and where smaller individuals may experience greater predation rates.

AB In 2011, a large multivessel survey was conducted to provide nearly synoptic sampling of Red Snapper Lutjanus campechanus throughout their reproductive season in the U.S. Gulf of Mexico. A total of 2,487 Red Snapper were caught with a female : male ratio that was approximately 1:1. The ovaries of 1,002 females were histologically examined. Females (n = 391) were found with spawning markers (postovulatory follicles and hydrated oocytes) throughout the study area, but primarily in outer shelf waters. Statistical models were developed to quantify and test the dependence of the proportion of females bearing spawning markers (spawning fraction) on female length and age, time of year, depth, gear type (vertical line or longline), or region (east or west of the Mississippi River). Most of the variance in spawning fraction was explained by the time of year; spawning fractions were generally low in spring, peaked in midsummer, and declined by fall. There was also strong statistical evidence of a positive relationship between spawning fraction and either age or length. The effects of region and gear type were not significant once time of year and size or age were accounted for. These results demonstrate the need to account for differences in the time of year and age structure of the population when the productivity of populations of Red Snapper are compared. For example, productivity has been hypothesized to be greater in the western Gulf than in the eastern Gulf, as evidenced by regional patterns of egg and larval abundance. Our results suggest that this regional difference is not due to any intrinsic difference in the biology of the fish, but simply a consequence of there being more large, old Red Snapper in the western Gulf. Recent stock assessments have indicated that Red Snapper are increasing in abundance and there is a need to continue monitoring to detect any possible compensation in reproduction.

AB We used microsatellite DNA data and genetic stock identification methods to delineate the temporal and spatial distributions of juvenile Chinook Salmon Oncorhynchus tshawytscha occupying coastal habitats extending from central Oregon to northern Washington. Juveniles were collected in trawl surveys conducted during spring, summer, and autumn over 15 years. Distributions (mean latitude and distance from shore) differed between yearling and subyearling life history types and between stocks; many of these differences were consistent across years. Yearlings were nearly all (98%) from Columbia River sources, and only 6% were naturally produced. In late May, yearlings from the lower Columbia and Willamette rivers were farther north than other yearlings, likely due to the early spring timing of their releases from hatcheries and subsequent out-migration from the Columbia River. However, yearling distributions in late June reflected known migration behaviors. Yearlings from interior Columbia and Snake River sources were farthest north by June, whereas yearlings from other stocks were more spread out in latitude. Subyearlings sampled in early summer were also largely from the Columbia River (98%), but greater percentages of subyearlings from coastal rivers were present during the fall (24%). In contrast to yearlings, natural production accounted for nearly one-third of subyearlings. Subyearlings of most stocks tended to remain relatively near their point of sea entry throughout the summer. Subyearlings from the Snake River fall-run stock and upper Columbia River summer-fall-run stock exhibited diverse distributions that included both southward and northward dispersal. Overall, distributions of Chinook Salmon stocks and life history types reflected differences in migration behavior but also reflected the influence of environmental factors and hatchery practices.

AB We examined physical and biological indices from Pacific salmon Oncorhynchus spp. surveys and commercial fisheries to index nearshore rearing habitats used by age-0 and age-1 Sablefish Anoplopoma fimbria in the eastern Gulf of Alaska and as indicators for their recruitment to age2 during the period 2001-2013. The best-fitting general linear model used to estimate age-2 Sablefish recruitment included chlorophyll-a concentration during late August and an index of juvenile Pink Salmon O. gorbuscha abundance during the age-0 stage of Sablefish. The model and biophysical indices from 2012 and 2013 produced a forecast of 23 million age-2 Sablefish for 2014 and a forecast of 8 million Sablefish for 2015. This study highlights the opportunity to use proxies for direct ambient physical and biological observations of rearing habitats in estimating groundfish recruitment to older ages.

AB The fecundity of Gray Triggerfish Balistes capriscus has been difficult to estimate, as few imminently spawning or recently spawned females have been detected. Our study focused on verifying the pattern of oogenesis and fecundity type in Gray Triggerfish. During 1999-2012, females (n = 1,092) were collected from the eastern Gulf of Mexico, and subsets of these fish were used to calculate condition indices and assess ovarian histology. The gonadosomatic index, hepatosomatic index, and Fulton's condition factor indicated that liver and somatic energy stores increased prior to spawning and were depleted throughout the spawning period, characteristic of a capital pattern of energy storage and allocation to reproduction. Typical of a capital breeding pattern, we also observed (1) a hiatus in oocyte size distribution and (2) group-synchronous oogenesis, which are both traits of a determinate fecundity type. However, evidence that fecundity was not set prior to spawning included the observation of de novo vitellogenesis during the spawning season; secondary oocytes increased in number and failed to increase in mean size over time. Thus, Gray Triggerfish exhibit an indeterminate fecundity type with mixed reproductive traits that may characterize species exhibiting female parental care in warmwater environments. Further, we estimated the secondary oocyte growth rate (37 mu m/d) based upon the time lag of postovulatory follicle (POF) degeneration. Using oocyte growth rate and the proportion of females bearing POFs, the interspawning interval was estimated to range from 8 to 11 d, indicating that 8-11 batches/female could be produced during the estimated 86-d reproductive period. The hiatus in oocyte size distribution was used to define a minimum size (250 mu m) from which to distinguish an advancing batch of secondary growth oocytes. Batch fecundity (BF) ranged from 0.34 to 1.99 million eggs and was significantly related to FL (mm): BF = 8,703.69 FL - 1,776,483 (r(2) = 0.56).

AB Variability in the late-summer vertical distribution of age-0 Walleye Pollock Gadus chalcogrammus in the southeastern Bering Sea has been attributed to a range of physical and biological factors. Using acoustic data (38 and 120 kHz) collected during the 2010 Bering Aleutian Salmon International Survey (BASIS) and dedicated high-resolution surveys (HR1 and HR2), we evaluated whether late-summer distributions could be explained by water column properties (environment) or whether sampling was likely occurring during the ontogenetic shift of age-0 Walleye Pollock from near-surface habitat to demersal habitat (ontogeny). Neither water column attributes (temperature, relative temperature, salinity, dissolved oxygen, and density gradient) nor the acoustic density of zooplankton prey strongly predicted the acoustic estimates of age-0 Walleye Pollock vertical presence or density. At 6 of 10 paired BASIS-HR1 stations, age-0 Walleye Pollock shifted deeper in the water column between BASIS sampling and the HR1 sampling conducted 8-34 d later. There were no consistent differences in FL (P > 0.05 for 2 of 4 station pairs) or energy density (P > 0.05 for 3 station pairs) between age-0 Walleye Pollock caught in near-surface trawls and those caught in midwater trawls. Our data suggest that the observation of both near-surface and midwater age-0 Walleye Pollock during late summer is likely due to an ontogenetic habitat shift; however, the causative factor was not clear given the limited sample sizes and explanatory variables. The timing of the ontogenetic shift, which appears to have begun before August 18, 2010, can ultimately affect survey strategies, and knowledge of this timing can provide additional insight into factors affecting the overwinter survival of age-0 Walleye Pollock.

AB Juvenile salmon transitioning from freshwater to marine environments experience high variation in growth and survival, yet the specific causes of this variation are poorly understood. Size at and timing of ocean entry may contribute to this variation because they influence both the availability of prey and vulnerability to predators. To explore this issue, we used stock assignments based on genetic stock identification and internal tags to document the stock-specific size and timing of juvenile hatchery and presumed wild Columbia River Chinook Salmon Oncorhynchus tshawytscha and steelhead O. mykiss at ocean entry during 2007-2011. We found that juvenile salmon and steelhead had consistent stock-specific capture dates, with lower-river stocks typically having earlier timing than those originating farther upstream. Mean size also varied among stocks and was related to hatchery practices. Hatchery yearling Chinook Salmon and steelhead were consistently larger than wild fish from the same stocks, although timing in the estuary was similar. In contrast, hatchery subyearling Chinook Salmon were of similar size to wild fish but entered the ocean up to a month earlier. We evaluated the potential importance of these traits on early marine growth by estimating stock-specific growth rates for Chinook Salmon caught in estuarine and ocean habitats. Growth rates were related to relative ocean entry timing, with lower growth rates for stocks that had only recently arrived in marine waters. Our results demonstrate that stocks within a single basin can differ in their size and timing of ocean entry, life history traits that contribute to early marine growth and potentially to the survival of juvenile salmon. Our results also highlight the necessity of considering stock-specific variation in life history traits to understand salmon ecology and survival across the entire life cycle.

AB Manganese is a commonly found constituent in fish otoliths, yet a direct correlation with ambient water concentrations as observed for other elements has proven elusive. There is compelling evidence that Mn uptake is related to the availability of reduced Mn (Mn2+) resulting from hypoxia (Limburg et al. 2015) but that fish growth rate also plays a role. We tested the latter possibility by examining otoliths from anadromous river herring (Alewife Alosa pseudoharengus and Blueback Herring A. aestivalis) in New York waters. A significant correlation was found between the ages at which shifts in otolith daily growth increments (assumed proportional to somatic growth) and shifts in otolith Mn: Ca ratios were detected. Furthermore, significant positive Spearman's rank correlations were observed between mean otolith daily growth and otolith Mn: Ca. Species-and site-specific differences were evident, but significant positive correlations were found for these relationships within each species and at most sampling sites. Ambient water concentrations were weakly correlated with otolith Mn: Ca, suggesting that both exogenous and endogenous factors influence Mn: Ca in otoliths. Thus, while endogenous mechanisms (i.e., growth rate) likely influence Mn uptake, exogenous availability is the ultimate control.

AB For many fishes, reproducing early in the year may present tradeoffs for the offspring: the drawbacks associated with harsh environmental conditions may be offset by advantages in competition for food and space. We investigated this tradeoff in a system where hatchery-origin steelhead Oncorhynchus mykiss were bred to spawn about 4 months earlier than wild-origin fish. Hatchery-origin adults were released into the wild and spawned in common with wild steelhead. Naturally spawned offspring from these matings were assigned to hatchery, wild, and hybrid lineages by using a panel of 96 single-nucleotide polymorphisms. We then evaluated whether fry abundance, body size and condition, and geographic distribution differed based on parental lineage. The observed mixture proportions were 0.007 hatchery-lineage, 0.289 hybrid, and 0.704 wild-lineage juveniles, despite the predominance of hatchery-origin parents. There were significant differences in FL (hatchery > hybrid > wild) but no difference in body condition. We modeled the emergence dates of the sampled fry and estimated that 96.0% of wild-lineage fish emerged after the arrival of temperate spring conditions (reduced flows and warmer temperatures) compared with 80.4% of hybrids and 41.2% of hatchery-lineage fish. We hypothesize that the low abundance of pure hatchery-lineage fry may be due to a mismatch between the timing of breeding by the parents and suitable river conditions, resulting in low survival and physical displacement of hatchery-lineage fry from the system. Thus, the advantages of early emergence and large size associated with hatchery origin did not mitigate the disadvantages of early spawning in this case.

TI Modified Water Diversion Structures Can Behaviorally Deter Juvenile
Chinook Salmon from Entrainment

ID FISH PASSAGE; SALAR SMOLTS; ONCORHYNCHUS-TSHAWYTSCHA; LOUVER; SYSTEM
AB Juvenile Chinook Salmon Oncorhynchus tshawytscha traveling in river systems can become entrained by unscreened water diversions when they encounter inflow velocities that exceed their avoidance (i.e., swimming) ability. We tested the efficiency of three devices for deterring fish entrainment; the devices reduced the diversion's maximum inflow velocity by dispersing the inflow across a greater area so as to reduce fish entrainment without causing a decrease in water diversion rates. Tests were performed in a river simulation flume at a 0.15-m/s sweeping velocity in clear water conditions during the daytime and nighttime as well as in turbid water (daytime) conditions. Water was diverted at a rate of 0.57 m(3)/s through a 0.46-m-diameter pipe. The tested devices included (1) a widened box inlet (1.7 m long x 0.76 m wide x 0.76 m deep) with a trash rack mounted at its entrance (trash rack box), (2) a widened box inlet with a louver array mounted at the entrance (louver box), and (3) a 0.91-m-diameter cylinder perforated with 300 evenly spaced, 5-cm-diameter holes (perforated cylinder). During 2-h experiments under daytime conditions, 51.5 of 80 fish (on average) were entrained into the pipe when no device was used (i.e., control), and a fish's mean risk of becoming entrained when passing the pipe once was 14%. The mean entrainment risk during a single pipe passage event was reduced to 7% in the trash rack box treatment (i. e., 50% of the control value), 0.17% in the louver box treatment, and 0.20% in the perforated cylinder treatment. In comparison with the control, the mean number of entrained fish was reduced by 50% in the trash rack box treatment, by 97% in the louver box treatment, and by 93% in the perforated cylinder treatment. These devices also reduced the number of fish that were entrained during darkness or turbid daytime conditions. Our findings suggest that behavioral deterrence devices offer effective, low-cost alternatives to positive barrier fish screens by protecting juvenile Chinook Salmon from entrainment at water diversion pipes without reducing water pumping efficiency.

AB Nearly 30-year aerosol optical thickness (AOT) climate data record (CDR) derived from the operational satellite observations of National Ocean and Atmospheric Administration (NOAA) Advanced Very High Resolution Radiometer (AVHRR) is used to study the AOT trends over seventeen megacities in the coast zone (MCCZ). Linear trends are derived from monthly and seasonal mean AOT in the past three decades and used in the analysis. The results indicate the following: (1) AOT around a MCCZ in fast developing countries has relatively high value and a positive trend with a confidence level generally above 95%; (2) AOT around a MCCZ in industrialized countries has relatively low value and a negative trend with a confidence level generally above 95%; (3) AOT values and their trends show distinct seasonal variations in MCCZ, which can be explained somewhat by the seasonal variations of meteorological conditions. AOT trend is an effective index for examining the efficacy of air pollution control policies implemented for these megacities.

AB Advanced manufacturing depends on the timely acquisition, distribution, and utilization of information from machines and processes across spatial boundaries. These activities can improve accuracy and reliability in predicting resource needs and allocation, maintenance scheduling, and remaining service life of equipment. As an emerging infrastructure, cloud computing provides new opportunities to achieve the goals of advanced manufacturing. This paper reviews the historical development of prognosis theories and techniques and projects their future growth enabled by the emerging cloud infrastructure. Techniques for cloud computing are highlighted, as well as the influence of these techniques on the paradigm of cloud-enabled prognosis for manufacturing. Finally, this paper discusses the envisioned architecture and associated challenges of cloud-enabled prognosis for manufacturing. (C) 2015 CIRP.

AB Precision positioning of an object relative to a reference point is a common task in many activities of production engineering. Sensor technologies for single axis measurement, either linear or rotary, which form the fundamentals of measurement technologies for precision positioning, are reviewed. Multi-axis coordinate measurement methods such as triangulation and multilateration, as well as Cartesian and polar systems for specifying the position in a plane or three-dimensional (3D) space are then presented, followed by a discussion on traceability and standards. Some advanced applications of measurement technologies for precision positioning in manufacturing industries are also demonstrated. (C) 2015 CIRP.

AB Currently available transient tracers have different application ranges that are defined by their temporal input (chronological transient tracers) or their decay rate (radioactive transient tracers). Transient tracers range from tracers for highly ventilated water masses such as sulfur hexafluoride (SF6) through tritium (H-3) and chlorofluorocarbons (CFCs) up to tracers for less ventilated deep ocean basins such as argon-39 (Ar-39) and radiocarbon (C-14). In this context, highly ventilated water masses are defined as water masses that have been in contact with the atmosphere during the last decade. Transient tracers can be used to empirically constrain the transit time distribution (TTD), which can often be approximated with an inverse Gaussian (IG) distribution. The IG-TTD provides information about ventilation and the advective/diffusive characteristics of a water parcel. Here we provide an overview of commonly used transient tracer couples and the corresponding application range of the IG-TTD by using the new concept of validity areas. CFC-12, CFC-11 and SF6 data from three different cruises in the South Atlantic Ocean and Southern Ocean as well as Ar-39 data from the 1980s and early 1990s in the eastern Atlantic Ocean and the Weddell Sea are used to demonstrate this method. We found that the IG-TTD can be constrained along the Greenwich Meridian south to 46 degrees S, which corresponds to the Subantarctic Front (SAF) denoting the application limit. The Antarctic Intermediate Water (AAIW) describes the limiting water layer in the vertical. Conspicuous high or lower ratios between the advective and diffusive components describe the transition between the validity area and the application limit of the IG-TTD model rather than describing the physical properties of the water parcel. The combination of Ar-39 and CFC data places constraints on the IG-TTD in the deep water north of the SAF, but not beyond this limit.

ID ENVIRONMENTS
AB This article is a review of how indoor air quality has been addressed in case studies of high-performing buildings, specifically the case studies described in ASHRAE's High Performing Buildings magazine. Nearly all of the reported case studies address energy performance, both in the design and operation of the building. In contrast, while most case studies mention indoor air quality design considerations, they generally do not address indoor air quality in a comprehensive manner, nor do they present the impacts of indoor air quality-related and other design considerations on indoor concentrations or on the health, comfort, and productivity of building occupants. Based upon this analysis, as well as existing standards and guidelines, a discussion is provided about what indoor air quality information should be collected during the early stages of a building's operation to demonstrate its indoor air quality performance. This information includes (a) documentation of key indoor air quality-related design features and their implementation during building construction, commissioning, and initial operation; (b) collection of indoor air quality performance data, including measured pollutant concentrations and ventilation rates; and (c) assessment of occupant satisfaction using occupant surveys. To facilitate comparisons of indoor air quality performance among buildings, suggestions are provided on how to collect and report this information in a consistent manner.

SO SCIENCE AND TECHNOLOGY FOR THE BUILT ENVIRONMENT

DT Article
ID MICRO-FIN TUBE
AB This article is an evaluation of the cycle performance of 39 refrigerants identified in the AHRI Low Global Warming Potential Alternative Refrigerants Evaluation Program in a typical air conditioner. This program was initiated in response to environmental concerns raised by the use of high global warming potential refrigerants with the intent to identify and evaluate promising alternative refrigerants. The cycle performance of each refrigerant is calculated assuming the same evaporator heat duty and sink temperatures for the condenser. The evaluation included the effects of heat transfer and pressure drop in the evaporator and the condenser. Four performance variables were investigated: (1) the coefficient of performance, (2) the required volumetric displacement of the compressor, (3) the mean temperature difference of the evaporator, and (4) the compressor discharge superheat. Ratios of the above four parameters relative to the refrigerants that are intended to be replaced are provided for each replacement refrigerant. In addition, amethodology was developed using weighting factors to rank the alternative refrigerants either emphasizing the importance of a large coefficient of performance or the importance of reduced system size. The two ranking methodologies produced different rankings of the alternative refrigerants, although the top three ranked refrigerants had at least two refrigerants in common with each other. Both ranking methodologies identified R1234yf, R32, and R1270 as having ranking factors within those of the best three alternative refrigerants.

AB Data assimilation systems allow for estimating surface fluxes of greenhouse gases from atmospheric concentration measurements. Good knowledge about fluxes is essential to understand how climate change affects ecosystems and to characterize feedback mechanisms. Based on the assimilation of more than 1 year of atmospheric in situ concentration measurements, we compare the performance of two established data assimilation models, CarbonTracker and TM5-4DVar (Transport Model 5 - Four-Dimensional Variational model), for CO2 flux estimation. CarbonTracker uses an ensemble Kalman filter method to optimize fluxes on ecoregions. TM5-4DVar employs a 4-D variational method and optimizes fluxes on a 6 degrees x 4 degrees longitude-latitude grid. Harmonizing the input data allows for analyzing the strengths and weaknesses of the two approaches by direct comparison of the modeled concentrations and the estimated fluxes. We further assess the sensitivity of the two approaches to the density of observations and operational parameters such as the length of the assimilation time window.
Our results show that both models provide optimized CO2 concentration fields of similar quality. In Antarctica CarbonTracker underestimates the wintertime CO2 concentrations, since its 5-week assimilation window does not allow for adjusting the distant surface fluxes in response to the detected concentration mismatch. Flux estimates by CarbonTracker and TM5-4DVar are consistent and robust for regions with good observation coverage, regions with low observation coverage reveal significant differences. In South America, the fluxes estimated by TM5-4DVar suffer from limited representativeness of the few observations. For the North American continent, mimicking the historical increase of the measurement network density shows improving agreement between CarbonTracker and TM5-4DVar flux estimates for increasing observation density.

TI Past changes in the vertical distribution of ozone - Part 3: Analysis
and interpretation of trends

AB Trends in the vertical distribution of ozone are reported and compared for a number of new and recently revised data sets. The amount of ozone-depleting compounds in the stratosphere (as measured by equivalent effective stratospheric chlorine - EESC) was maximised in the second half of the 1990s. We examine the periods before and after the peak to see if any change in trend is discernible in the ozone record that might be attributable to a change in the EESC trend, though no attribution is attempted. Prior to 1998, trends in the upper stratosphere (similar to 45 km, 4 hPa) are found to be -5 to -10% per decade at mid-latitudes and closer to -5% per decade in the tropics. No trends are found in the mid-stratosphere (28 km, 30 hPa). Negative trends are seen in the lower stratosphere at mid-latitudes in both hemispheres and in the deep tropics. However, it is hard to be categorical about the trends in the lower stratosphere for three reasons: (i) there are fewer measurements, (ii) the data quality is poorer, and (iii) the measurements in the 1990s are perturbed by aerosols from the Mt Pinatubo eruption in 1991. These findings are similar to those reported previously even though the measurements for the main satellite and ground-based records have been revised.
There is no sign of a continued negative trend in the upper stratosphere since 1998: instead there is a hint of an average positive trend of similar to 2% per decade in mid-latitudes and similar to 3% per decade in the tropics. The significance of these upward trends is investigated using different assumptions of the independence of the trend estimates found from different data sets. The averaged upward trends are significant if the trends derived from various data sets are assumed to be independent (as in Pawson et al., 2014) but are generally not significant if the trends are not independent. This occurs because many of the underlying measurement records are used in more than one merged data set. At this point it is not possible to say which assumption is best. Including an estimate of the drift of the overall ozone observing system decreases the significance of the trends. The significance will become clearer as (i) more years are added to the observational record, (ii) further improvements are made to the historic ozone record (e. g. through algorithm development), and (iii) the data merging techniques are refined, particularly through a more rigorous treatment of uncertainties.

AB False killer whales Pseudorca crassidens and short-finned pilot whales Globicephala macrorhynchus are known to interact with long-line fishing gear in Hawaiian waters, causing economic loss and leading to whale injuries and deaths. The main Hawaiian Islands' insular population of false killer whales is listed as endangered and the offshore population is considered 'strategic' under the Marine Mammal Protection Act due to relatively high bycatch levels. Discriminating between these species acoustically is problematic due to similarity in the spectral content of their echolocation clicks. We used passive acoustic monitoring along with data from satellite tags to distinguish signals from these 2 species. Acoustic encounters recorded with autonomous instruments offshore of the islands of Hawai'i and Kaua'i were matched with concurrent and nearby location information obtained from satellite tagged individuals. Two patterns of echolocation clicks were established for the 2 species. The overall spectral click parameters were highly similar (22 kHz peak and 25 kHz center frequency), but false killer whales had shorter duration and broader bandwidth clicks than short-finned pilot whales (225 mu s, 8 kHz [-3 dB bandwidth] and 545 mu s, 4 kHz, respectively). Also, short-finned pilot whale clicks showed distinct spectral peaks at 12 and 18 kHz. Automated classification techniques using Gaussian mixture models had a 6.5% median error rate. Based on these findings for echolocation clicks and prior published work on whistle classification, acoustic encounters of false killer whales and short-finned pilot whales on autonomous instruments should be identifiable to species level, leading to better long-term monitoring with the goal of mitigating bycatch.

AB The evolutionary history of flatfishes dates back to the early Tertiary. Currently, 14 families and 123 genera are recognised in this third most diverse order of marine euteleosts. Of 1363 nominal species described or currently recognized by taxonomists, 822 are valid. A species accumulation curve for flatfishes reveals that we are not yet close to knowing the total diversity of this group. Since 2000, approximately 10% of flatfish diversity was described and another 4% recognized as new to science. Species-rich families include Soleidae, Cynoglossidae and Bothidae. Geographic occurrence, size and distributions of species, and activities of systematists influence rates of species discovery. Species accumulation curves for flatfishes inhabiting temperate and Arctic regions indicate species discoveries still occur there but at much slower rates than for flatfishes of tropical waters. Considerable diversity remains to be discovered in tropical marine waters and flatfish taxonomy continues to be an active area of research.

AB Flatfishes inhabit marine, estuarine and freshwater environments from the southern Arctic Ocean to continental seas off Antarctica. Geographical and ecological distributions reveal distinctly asymmetrical global patterns of flatfish species diversity. The greatest diversity is found in marine waters of the Indo-West Pacific; other tropical seas support fewer species (diversity decreases progressively from western Atlantic, tropical Eastern Pacific, to Eastern Atlantic, respectively). Fewer species inhabit temperate waters, while the least diverse flatfish assemblages are in northern and southern polar waters and at isolated islands. Ecologically, flatfishes range from estuaries to the outer continental shelf and upper continental slope to about 2000 m. Notable differences in diversity occur between continental and insular locations. Few species inhabit freshwaters. Maximal species richness within regions occurs on extensive continental shelves featuring complex shallow-water (< 200 m) habitats. Phylogenetic studies of interrelationships and intrarelationships of flatfishes are currently insufficient for analyses of their historical biogeography.

AB Flatfish address the problem of connecting between spatially distinct adult spawning areas and juvenile nursery areas through a planktonic larval phase. This strategy minimizes interspecific competition, promotes genetic diversity, and offers opportunities to colonize new habitats, but it comes at the significant risk of wayward advection and settlement to unsuitable nursery areas. Flatfishes have maximized their chances of a successful planktonic gamble by timing production of offspring to co-occur with favourable atmospheric conditions and with oceanographic features that favour survival to settlement. Broad-scale changes in climate-ocean teleconnections threaten to modulate the spatio-temporal relationship between the planktonic larvae and their ocean habitat, including physiological shifts (temperature and developmental timing), ecological changes (circulation and influences on transport trajectory), and behavioural affects (feeding and swimming). Renewed effort to understand these changes and others is called for.

AB A global summary indicates that, in general, flatfishes feed on worms, small crustaceans, fishes, and squid, with a few specialist feeders (e.g., echinoderms or bivalve siphons). Morphology, ontogeny, and prey spatio-temporal availability determine the diet. In some cases, predation by flatfishes can have significant impacts on their prey populations. Flatfishes are also eaten by many different predators, and the degree of predation varies across life history and may influence annual variations in year-class strength. Flatfishes can have high spatial, temporal and dietary overlaps with other species, and coupled with opposite trends in abundance of possible competitor populations suggest that competitive processes do occur. Better assessments of in situ competition and population-level impacts are fruitful areas for further research. Understanding the impacts of changes to benthic communities, and their broader implications for flatfishes, also warrants further attention.

AB This chapter provides an overview of the principal aspects of flatfish behaviour during the benthic stage of their life history. It concentrates on the activities of spawning, feeding and reactions to predators that enable flatfishes to reproduce, grow and survive. These activities take place over a wide range of spatial scales from localized foraging to long-distance migrations and a brief account of movement patterns that have evolved to make the most effective use of the environment is included. Finally, aspects of flatfish behaviour that are important in relationships with humans, including the design of fishing gear, culturing practices and stock enhancement are discussed.

AB The Pacific Ocean is the largest and deepest of the earth's oceans, covers 28% of the global surface and is the habitat for approximately 300 flatfish species ranging from nearshore estuarine areas to deep waters of the continental slope. Flatfish harvesting by coastal nations has occurred for centuries and is comprised today of a variety of fishing vessels (small to large) whose economic product value is estimated at over $US 960 million annually. In Japan and Korea the fish are either kept alive or sold fresh to the local market, thereby commanding a high price. Most flatfishes are harvested by trawling and products typically include frozen at sea, headed and eviscerated fish, fillets, whole frozen fish, kirimi or fish meal. Governance for Pacific flatfish fisheries is typically regional and generally features domestic-licensed limited entry, with or without individual harvester quota shares on a total quota (depending on management area).

AB Tropical seas represent one of the largest marine biomes on earth and have diverse assemblages of marine flatfishes (616+ species). Tropical coastlines support large human populations with approximately 95% of the world's fisher population having access to 60% of the world's fishery resources. Within tropical seas and estuaries, anthropogenic factors affect the greatest diversity of flatfishes found anywhere. Tropical fisheries land only a small proportion of the total diversity of flatfishes directly for human consumption, but large numbers are also killed or damaged during industrial and artisanal trawl fisheries operations. As more desirable fish species become scarcer due to overfishing, more flatfishes are marketed to meet increasing local demands for fish protein. Overfishing and habitat destruction pose the most serious threats to tropical flatfishes. Basic life-history and ecological information is wanting for the majority of tropical flatfishes, therefore, only limited approaches are available to protect these species from over-exploitation.

AB Eight surface observation sites providing quasi-continuous measurements of atmospheric methane mixing ratios have been operated since the mid-2000's in Siberia. For the first time in a single work, we assimilate 1 year of these in situ observations in an atmospheric inversion. Our objective is to quantify methane surface fluxes from anthropogenic and wetland sources at the mesoscale in the Siberian lowlands for the year 2010. To do so, we first inquire about the way the inversion uses the observations and the way the fluxes are constrained by the observation sites. As atmospheric inversions at the mesoscale suffer from mis-quantified sources of uncertainties, we follow recent innovations in inversion techniques and use a new inversion approach which quantifies the uncertainties more objectively than the previous inversion systems. We find that, due to errors in the representation of the atmospheric transport and redundant pieces of information, only one observation every few days is found valuable by the inversion. The remaining high-resolution quasi-continuous signal is representative of very local emission patterns difficult to analyse with a mesoscale system. An analysis of the use of information by the inversion also reveals that the observation sites constrain methane emissions within a radius of 500 km. More observation sites than the ones currently in operation are then necessary to constrain the whole Siberian lowlands. Still, the fluxes within the constrained areas are quantified with objectified uncertainties. Finally, the tolerance intervals for posterior methane fluxes are of roughly 20% (resp. 50 %) of the fluxes for anthropogenic (resp. wetland) sources. About 50-70% of Siberian lowlands emissions are constrained by the inversion on average on an annual basis. Extrapolating the figures on the constrained areas to the whole Siberian lowlands, we find a regional methane budget of 5-28 TgCH(4) for the year 2010, i.e. 1-5% of the global methane emissions. As very few in situ observations are available in the region of interest, observations of methane total columns from the Greenhouse Gas Observing SATellite (GOSAT) are tentatively used for the evaluation of the inversion results, but they exhibit only a marginal signal from the fluxes within the region of interest.

AB The Magnuson-Stevens Fishery Conservation and Management Reauthorization Act of 2006 required regional fishery management councils to implement annual catch limits (ACLs) for nearly all stocks under U.S. federal management. Since 2011, the number of stocks requiring ACLs (and monitoring) has increased nearly 10-fold, with strict accountability measures requiring either in-season quota closures or shortening of subsequent seasons to avoid ACL overages. Robust forecasts of landings can also provide a projected baseline for evaluation of proposed management alternatives. We compared generalized linear models (GLMs), generalized additive models (GAMs), and seasonal autoregressive integrated moving average (SARIMA) models in terms of fit, accuracy, and ability to forecast landings of four representative fish stocks that support recreational fisheries in the southeastern United States. All models were useful in developing reliable forecasts to inform management. The GAMs provided the best fit to the observed data; however, the modeling approaches of the SARIMA model and GLM provided the best forecasts for most scenarios. The SARIMA model and GLM also provided the best predictions of the seasonal trend in landings, a desirable feature for in-season quota monitoring. The SARIMA model was more sensitive and the GLM was less sensitive to recent trends, providing a useful "bookend" for forecasts. The time span of input data affected forecast accuracy from all model types considered. This study suggests multiple forecasting models should be investigated and performance metrics carefully selected and evaluated, as no single model is likely to perform best for all stocks of interest.

AB Predation by marine birds has resulted in substantial losses to runs of Pacific salmon Oncorhynchus spp., in some cases necessitating management action. Recovery of PIT tags on a seabird breeding colony (Ano Nuevo Island) indicated that western gulls Larus occidentalis prey upon federally listed Coho Salmon Oncorhynchus kisutch and steelhead O. mykiss in central California. Whereas salmonid populations in central California have decreased in recent decades, the western gull population on Ano Nuevo Island has increased. We observed gulls Larus spp. within estuaries to document predation and used radiotelemetry to examine gull movement in relation to the availability of salmonids. During 2008 and 2009, observed predation events of out- migrating salmonids by gulls were rare; 21 events occurred during 338 h of observations at two estuaries. During the prehatch and chick-rearing phases of breeding, which coincided with migration of salmonids from fresh to salt water, 74% of the detections of radio-tagged western gulls occurred within 25 km of Ano Nuevo Island, suggesting that the relative susceptibility of predation by western gulls using Ano Nuevo Island decreased with distance from the island. Western gull presence at creek mouths was greatest during daylight hours (91% of detections), while juvenile salmonids were present predominantly at night (65% of detections). The greatest overlap between western gulls and salmonids occurred at dusk, and predation of out-migrating salmonids was likely opportunistic. Deterring gulls from creek mouths when overlap between predator and prey might otherwise occur may buffer out-migrating salmonids from predation. Our results will inform management strategies to most effectively reduce the impacts of gull predation on central California salmonids.

AB We present the first experimental study on the simultaneous capillary instability amongst viscous concentric rings suspended atop an immiscible medium. The rings ruptured upon annealing, with three types of phase correlation between neighboring rings. In the case of weak substrate confinement, the rings ruptured independently when they were sparsely distanced, but via an out-of-phase mode when packed closer. If the substrate confinement was strong, the rings would rupture via an in-phase mode, resulting in radially aligned droplets. The concentric ring geometry caused a competition between the phase correlation of neighboring rings and the kinetically favorable wavelength, yielding an intriguing, recursive surface pattern. This frustrated pattern formation behavior was accounted for by a scaling analysis.

AB The complexity of the relationship of strategic goals to operational performance across the many levels of a manufacturing system inhibits the realization of Smart Manufacturing Systems (SMS). This paper proposes a method for identifying what aspects of a manufacturing system should be addressed to respond to changing strategic goals. The method uses standard techniques in specifying a manufacturing system and the relationship between strategic goals and operational performance metrics. Two existing reference models related to manufacturing operations are represented formally and integrated to support the proposed method. The method is illustrated for a single scenario using agility as a strategic goal.

AB We present Van Allen Probe B observations of azimuthally limited, antisymmetric, poloidal Pc 4 electric and magnetic field pulsations in the pre-midnight sector of the magnetosphere from 05:40 to 06:00 UT on 1 May 2013. Oscillation periods were similar for the magnetic and electric fields and proton fluxes. The flux of energetic protons exhibited an energy-dependent response to the pulsations. Energetic proton variations were anticorrelated at medium and low energies. Although we attribute the pulsations to a drift-bounce resonance, we demonstrate that the energy-dependent response of the ion fluxes results from pulsation-associated velocities sweeping energy-dependent radial ion flux gradients back and forth past the spacecraft.

AB Coronal mass ejection (CME)-shock compression of the dayside magnetopause has been observed to cause both prompt enhancement of radiation belt electron flux due to inward radial transport of electrons conserving their first adiabatic invariant and prompt losses which at times entirely eliminate the outer zone. Recent numerical studies suggest that enhanced ultra-low frequency (ULF) wave activity is necessary to explain electron losses deeper inside the magnetosphere than magnetopause incursion following CME-shock arrival. A combination of radial transport and magnetopause shadowing can account for losses observed at radial distances into L = 4.5, well within the computed magnetopause location. We compare ULF wave power from the Electric Field and Waves (EFW) electric field instrument on the Van Allen Probes for the 8 October 2013 storm with ULF wave power simulated using the Lyon-Fedder-Mobarry (LFM) global magnetohydrodynamic (MHD) magnetospheric simulation code coupled to the Rice Convection Model (RCM). Two other storms with strong magnetopause compression, 8-9 October 2012 and 17-18 March 2013, are also examined. We show that the global MHD model captures the azimuthal magnetosonic impulse propagation speed and amplitude observed by the Van Allen Probes which is responsible for prompt acceleration at MeV energies reported for the 8 October 2013 storm. The simulation also captures the ULF wave power in the azimuthal component of the electric field, responsible for acceleration and radial transport of electrons, at frequencies comparable to the electron drift period. This electric field impulse has been shown to explain observations in related studies (Foster et al., 2015) of elec-tron acceleration and drift phase bunching by the Energetic Particle, Composition, and Thermal Plasma Suite (ECT) instrument on the Van Allen Probes.

KINETIC MEASUREMENTS
AB Laboratory experiments of efficient oligomerization from methyl vinyl ketone (MVK) in the bulk aqueous phase were simulated in a box model. Kinetic data are applied (if known) or fitted to the observed MVK decay and oligomer mass increase. Upon model sensitivity studies, in which unconstrained rate constants were varied over several orders of magnitude, a set of reaction parameters was found that could reproduce laboratory data over a wide range of experimental conditions.
This mechanism is the first that comprehensively describes such radical-initiated oligomer formation. This mechanism was implemented into a multiphase box model that simulates secondary organic aerosol (SOA) formation from isoprene, as a precursor of MVK and methacrolein (MACR) in the aqueous and gas phases. While in laboratory experiments oxygen limitation might occur and lead to accelerated oligomer formation, such conditions are likely not met in the atmosphere. The comparison of predicted oligomer formation shows that MVK and MACR likely do negligibly contribute to total SOA as their solubilities are low and even reduced in aerosol water due to ionic strength effects (Setchenov coefficients). Significant contribution by oligomers to total SOA might only occur if a substantial fraction of particulate carbon acts as oligomer precursors and/or if oxygen solubility in aerosol water is strongly reduced due to salting-out effects.

AB Organic nitrates in both gas and condensed (aerosol) phases were measured during the Uintah Basin Winter Ozone Study from January to February in 2012. A high degree of correlation between total aerosol volume at diameters less than 500 nm and the particulate organic nitrate concentration indicates that organic nitrates are a consistent, if not dominant, fraction of fine aerosol mass. In contrast, a similar correlation with sub-2.5 mu m aerosol volume is weaker. The C : N atomic ratio inferred from field measurements of PM2.5 and particulate organic nitrate is 34 : 1. Calculations constrained by the observations indicate that both condensation of gas-phase nitrates and heterogeneous reactions of NO3 / N2O5 are responsible for introducing organic nitrate functionality into the aerosol and that the source molecules are alkanes. Extrapolating the results to urban aerosol suggests organic nitrate production from alkanes may be a major secondary organic aerosol source.

AB The concentrations of sulfate, black carbon (BC) and other aerosols in the Arctic are characterized by high values in late winter and spring (so-called Arctic Haze) and low values in summer. Models have long been struggling to capture this seasonality and especially the high concentrations associated with Arctic Haze. In this study, we evaluate sulfate and BC concentrations from eleven different models driven with the same emission inventory against a comprehensive pan-Arctic measurement data set over a time period of 2 years (2008-2009). The set of models consisted of one Lagrangian particle dispersion model, four chemistry transport models (CTMs), one atmospheric chemistry-weather forecast model and five chemistry climate models (CCMs), of which two were nudged to meteorological analyses and three were running freely. The measurement data set consisted of surface measurements of equivalent BC (eBC) from five stations (Alert, Barrow, Pallas, Tiksi and Zeppelin), elemental carbon (EC) from Station Nord and Alert and aircraft measurements of refractory BC (rBC) from six different campaigns. We find that the models generally captured the measured eBC or rBC and sulfate concentrations quite well, compared to previous comparisons. However, the aerosol seasonality at the surface is still too weak in most models. Concentrations of eBC and sulfate averaged over three surface sites are underestimated in winter/spring in all but one model (model means for January-March underestimated by 59 and 37% for BC and sulfate, respectively), whereas concentrations in summer are overestimated in the model mean (by 88 and 44% for July-September), but with overestimates as well as underestimates present in individual models. The most pronounced eBC underestimates, not included in the above multi-site average, are found for the station Tiksi in Siberia where the measured annual mean eBC concentration is 3 times higher than the average annual mean for all other stations. This suggests an underestimate of BC sources in Russia in the emission inventory used. Based on the campaign data, biomass burning was identified as another cause of the modeling problems. For sulfate, very large differences were found in the model ensemble, with an apparent anti-correlation between modeled surface concentrations and total atmospheric columns. There is a strong correlation between observed sulfate and eBC concentrations with consistent sulfate/eBC slopes found for all Arctic stations, indicating that the sources contributing to sulfate and BC are similar throughout the Arctic and that the aerosols are internally mixed and undergo similar removal. However, only three models reproduced this finding, whereas sulfate and BC are weakly correlated in the other models. Overall, no class of models (e.g., CTMs, CCMs) performed better than the others and differences are independent of model resolution.

TI Interactions of bromine, chlorine, and iodine photochemistry during

AB The springtime depletion of tropospheric ozone in the Arctic is known to be caused by active halogen photochemistry resulting from halogen atom precursors emitted from snow, ice, or aerosol surfaces. The role of bromine in driving ozone depletion events (ODEs) has been generally accepted, but much less is known about the role of chlorine radicals in ozone depletion chemistry. While the potential impact of iodine in the High Arctic is more uncertain, there have been indications of active iodine chemistry through observed enhancements in filterable iodide, probable detection of tropospheric IO, and recently, observation of snowpack photochemical production of I-2. Despite decades of research, significant uncertainty remains regarding the chemical mechanisms associated with the bromine-catalyzed depletion of ozone, as well as the complex interactions that occur in the polar boundary layer due to halogen chemistry. To investigate this, we developed a zero-dimensional photochemical model, constrained with measurements from the 2009 OA-SIS field campaign in Barrow, Alaska. We simulated a 7-day period during late March that included a full ozone depletion event lasting 3 days and subsequent ozone recovery to study the interactions of halogen radicals under these different conditions. In addition, the effects of iodine added to our Base Model were investigated. While bromine atoms were primarily responsible for ODEs, chlorine and iodine were found to enhance the depletion rates and iodine was found to be more efficient per atom at depleting ozone than Br. The interaction between chlorine and bromine is complex, as the presence of chlorine can increase the recycling and production of Br atoms, while also increasing reactive bromine sinks under certain conditions. Chlorine chemistry was also found to have significant impacts on both HO2 and RO2, with organic compounds serving as the primary reaction partner for Cl atoms. The results of this work highlight the need for future studies on the production mechanisms of Br-2 and Cl-2, as well as on the potential impact of iodine in the High Arctic.

AB The impact of deglaciation in Glacier Bay has been observed to seasonally influence the biogeochemistry of this marine system. The influence from surrounding glaciers, particularly tidewater glaciers, has the potential to affect the efficiency and structure of the marine food web within Glacier Bay. To assess the magnitude and the spatial and temporal variability in net community production in a glaciated fjord, we measured dissolved inorganic carbon, inorganic macronutrients, dissolved oxygen, and particulate organic carbon between July 2011 and July 2012 in Glacier Bay, Alaska. High net community production rates were observed across the bay (similar to 54 to similar to 81 mmol C m(-2) d(-1)) between the summer and fall of 2011. However, between the fall and winter, as well as between the winter and spring of 2012, air-sea fluxes of carbon dioxide and organic matter respiration made net community production rates negative across most of the bay as inorganic carbon and macronutrient concentrations returned to pre-bloom levels. The highest organic carbon production occurred within the west arm between the summer and fall of 2011 with similar to 4.5 x 10(5) kg Cd-1. Bay-wide, there was carbon production of similar to 9.2 x 10(5) g Cd-1 between the summer and fall. Respiration and air-sea gas exchange were the dominant drivers of carbon chemistry between the fall and winter of 2012. The substantial spatial and temporal variability in our net community production estimates may reflect glacial influences within the bay, as meltwater is depleted in macronutrients relative to marine waters entering from the Gulf of Alaska in the middle and lower parts of the bay. Further glacial retreat will likely lead to additional modifications in the carbon biogeochemistry of Glacier Bay, with unknown consequences for the local marine food web, which includes many species of marine mammals.

ID SPATIAL-PATTERNS; MODEL
AB Humans cause more than 55% of wildfires on lands managed by the USDA Forest Service and US Department of the Interior, contributing to both suppression expenditures and damages. One means to reduce the expenditures and damages associated with these wildfires is through fire prevention activities, which can include burn permits, public service programs or announcements, outreach efforts to schools, youth groups and equipment operators, and law enforcement. Using data from 17 US Bureau of Indian Affairs tribal units, we modelled the effect of prevention programs and law enforcement on the number of human-caused ignitions. We also included weather and lagged burned area in our estimation of fixed-effects count models. The results show that prevention activities led to significant reductions in wildfires caused by escaped campfires, juveniles, fire-use (e.g. escaped debris burns) and equipment. Increased law enforcement resulted in fewer incendiary- and equipment-caused wildfires. Using average suppression expenditures by wildfire and our estimate of avoided wildfires per additional year of prevention, we estimate partial benefit-cost ratios of greater than 4.5 for all Bureau of Indian Affairs regions for the continuation of the prevention program.

AB Rising populations around coastal systems are increasing the threats to marine water quality. To assess anthropogenic fecal influence, subtidal waters were examined monthly for human-and ruminant-sourced Bacteroidales markers at 80 sites across six oceanographic basins of the Salish Sea (Washington State) from April through October, 2011. In the basins containing cities with individual populations >190,000, >50% of sites were positive for the human marker, while in the basins with high densities of dairy and cattle operations, similar to 30% of sites were positive for the ruminant marker. Marker prevalence was elevated in spring (April and May) and fall (October) and reduced during summer (June through September), corresponding with seasonal precipitation. By logistic regression, the odds of human marker detection increased with percentage of adjacent catchment impervious surface, dissolved nitrate concentration, and abundance of low nucleic acid bacteria, but decreased with salinity and chlorophyll fluorescence. The odds of ruminant marker detection increased with dissolved ammonium concentration, mean flow rate for the nearest river, and adjacent shoreline length. These relationships are consistent with terrestrial to marine water flow as a transport mechanism. Thus, Bacteroidales markers traditionally used for identifying nearby sources can be used for assessing anthropogenic fecal inputs to regional marine ecosystems.

AB Edge chipping is a common problem with ceramics used for dental restorations, consumer wares, substrates and wafers, and advanced ceramic structural applications. Concentrated contact forces applied near an edge can cause a flake to pop off. A method to quantify edge chipping resistance was developed National Physical Laboratory in the United Kingdom and applied to hard metal cutting tools, technical ceramics, and glasses. Early analyses emphasized a simple linear relationship between force and the distance away from the edge, but more extensive recent testing has revealed nonlinear trends. In this presentation, a new model for edge chipping resistance is presented that is based on energy balances between indenter work, material deformation and fracture.

ID ABSORPTION CROSS-SECTIONS; COEFFICIENTS
AB A comparison of retrieved total column ozone (TCO) amounts between the Pandora #34 spectrometer system and the Dobson #061 spectrophotometer from direct-sun observations was performed on the roof of the Boulder, Colorado, NOAA building. This paper, part of an ongoing study, covers a 1-year period starting on 17 December 2013. Both the standard Dobson and Pandora TCO retrievals required a correction, TCOcorr = TCO (1 + C(T)), using a monthly varying effective ozone temperature, T-E, derived from a temperature and ozone profile climatology. The correction is used to remove a seasonal difference caused by using a fixed temperature in each retrieval algorithm. The respective corrections C(T-E) are C-Pandora = 0.00333(T-E - 225) and C-Dobson = -0.0013 (T-E - 226.7) per degree K. After the applied corrections removed most of the seasonal retrieval dependence on ozone temperature, TCO agreement between the instruments was within 1% for clear-sky conditions. For clear-sky observations, both co-located instruments tracked the day-to-day variation in total column ozone amounts with a correlation of r(2) = 0.97 and an average offset of 1.1 +/- 5.8 DU. In addition, the Pandora TCO data showed 0.3% annual average agreement with satellite overpass data from AURA/OMI (Ozone Monitoring Instrument) and 1% annual average offset with Suomi-NPP/OMPS (Suomi National Polar-orbiting Partnership, the nadir viewing portion of the Ozone Mapper Profiler Suite).

AB The eruption of Mount Tambora (Indonesia) in April 1815 is the largest documented volcanic eruption in history. It is associated with a large global cooling during the following year, felt particularly in parts of Europe and North America, where the year 1816 became known as the "year without a summer". This paper describes an effort made to collect surface meteorological observations from the early instrumental period, with a focus on the years of and immediately following the eruption (1815-1817). Although the collection aimed in particular at pressure observations, correspondent temperature observations were also recovered. Some of the series had already been described in the literature, but a large part of the data, recently digitised from original weather diaries and contemporary magazines and newspapers, is presented here for the first time. The collection puts together more than 50 sub-daily series from land observatories in Europe and North America and from ships in the tropics. The pressure observations have been corrected for temperature and gravity and reduced to mean sea level. Moreover, an additional statistical correction was applied to take into account common error sources in mercury barometers. To assess the reliability of the corrected data set, the variance in the pressure observations is compared with modern climatologies, and single observations are used for synoptic analyses of three case studies in Europe. All raw observations will be made available to the scientific community in the International Surface Pressure Databank.

AB The Florida Current is the headwater of the Gulf Stream and is a component of the North Atlantic western boundary current from which a geostrophic balance between sea surface height and mass transport directly influence coastal sea levels along the Florida Straits. A linear regression of daily Florida Current transport estimates does not find a significant change in transport over the last decade; however, a nonlinear trend extracted from empirical mode decomposition (EMD) suggests a 3 Sv decline in mean transport. This decline is consistent with observed tide gauge records in Florida Bay and the straits exhibiting an acceleration of mean sea level (MSL) rise over the decade. It is not known whether this recent change represents natural variability or the onset of the anticipated secular decline in Atlantic meridional overturning circulation (AMOC); nonetheless, such changes have direct impacts on the sensitive ecological systems of the Everglades as well as the climate of western Europe and eastern North America.

Two improvements are given: sums are evaluated for isogenies of degree greater than two, and over arbitrary finite fields. We prove a transfer formula to evaluate such sums quickly over the domain curve and use this to evaluate the character sums attached to several standard families of isogenies of low degree.

AB Colloidal-probe spherical indentation load-relaxation experiments with a probe radius of 3 mm are conducted on poly(ethylene glycol) (PEG) hydrogel materials to quantify their steady-state mechanical properties and time-dependent transport properties via a single experiment. PEG-based hydrogels are shown to be heterogeneous in both morphology and mechanical stiffness at this scale; a linear-harmonic interpolation of hyperelastic Mooney-Rivlin and Boussinesq flat-punch indentation models was used to describe the steady-state response of the hydrogels and determine upper and lower bounds for indentation moduli. Analysis of the transient load-relaxation response during displacement-controlled hold periods provides a means of extracting two time constants tau(1) and tau(2), where tau(1) and tau(2) are assigned to the viscoelastic and poroelastic properties, respectively. Large tau(2) values at small indentation depths provide evidence of a non-equilibrium state characterized by a phenomenon that restricts poroelastic fluid flow through the material; for larger indentations, the variability in tau(2) values decreases and pore sizes estimated from tau(2) via indentation approach those measured via macroscopic swelling experiments. The contact probe methodology developed here provides a means of assessing hydrogel heterogeneity, including time-dependent mechanical and transport properties, and has potential implications in hydrogel biomedical and engineering applications.

AB Climate change threatens tropical coastal communities and ecosystems. Governments, resource managers, and communities recognize the value of assessing the social and ecological impacts of climate change, but there is little consensus on the most effective framework to support vulnerability and adaptation assessments. The framework presented in this research is based on a gap analysis developed from the recommendations of climate and adaptation experts. The article highlights social and ecological factors that affect vulnerability to climate change; adaptive capacity and adaptation options informing policy and conservation management decisions; and a methodology including criteria to assess current and future vulnerability to climate change. The framework is intended for conservation practitioners working in developing countries, small island nations, and traditional communities. It identifies core components that assess climate change impacts on coastal communities and environments at the local scale, and supports the identification of locally relevant adaptation strategies. Although the literature supporting vulnerability adaptation assessments is extensive, little emphasis has been placed on the systematic validation of these tools. To address this, we validate the framework using the Delphi technique, a group facilitation technique used to achieve convergence of expert opinion, and address gaps in previous vulnerability assessments.

AB Tropical coastal communities face the impacts of climate change with increasing frequency and severity, which exacerbates existing local threats to natural resources and the societies that depend on them. Climate change presents a unique opportunity to reconsider how community-based planning is used to (1) improve overall climate knowledge, both through communicating climate science and incorporating local knowledge; (2) give equal consideration to the social and ecological aspects of community health and resilience; and (3) integrate multisector planning to maximize community benefits and minimize unintended negative impacts. This article describes a tool developed to respond to these opportunities in Micronesia and the Coral Triangle region, Adapting to a Changing Climate: Guide to Local Early Action Planning (LEAP) and Management Planning. It discusses challenges and lessons learned based on the process of the tool development, training with local communities and stakeholders, and input from those who have implemented the tool.

AB This case study describes the climate adaptation planning efforts that were undertaken on the island of Saipan in the Commonwealth of the Northern Mariana Islands. This effort focused on establishing a multi-agency Climate Change Working Group. The adaptation planning efforts on Saipan used two main sources of guidance: one document written for application to coastal jurisdictions throughout the United States and a set of tools designed for small island communities in the Pacific. These sources were combined with inspiration from adaptation processes in other jurisdictions and adjustments were made to fit Saipan's situation. Modifications were based on available knowledge or expertise, technical capacities, and local needs. Several themes that are common to adaptation processes elsewhere were important in Saipan: leadership and political will, stakeholder involvement, level of climate knowledge, building on existing collaborations, and technical capacity. These themes are examined, with an emphasis on how we adjusted to meet the challenges that arose in the context of Saipan's social, political, and economic landscape.

ID ADAPTIVE CAPACITY; ASSESSMENTS
AB Conservation and development organizations conduct vulnerability and adaptation assessments to assess the vulnerability of coastal communities and ecosystems to climate change and to identify adaptation strategies to address these impacts. Local assessments are needed to provide this information at the scale of communities and critical habitats. Over the last decade, there has been a proliferation of tools developed to assess climate vulnerability and adaptation at the community level. However, there has been limited synthesis of the available tools across disciplines in the peer-reviewed literature and limited guidance provided to help conservation practitioners and development planners select which tool is most appropriate for a given application. This article reviews a number of tools designed for community-level climate vulnerability and adaptation assessments and highlights their advantages and limitations to help managers make informed decisions about tool selection. Selection of tools will involve tradeoffs in terms of the capacity and resources needed to apply the tools and the aspects of social and ecological vulnerability that they address.

AB Cross-referenced parallel markup for mathematics allows the combination of both presentation and content representations while associating the components of each. Interesting applications are enabled by such arrangements: interaction with parts of the presentation to manipulate and query the corresponding content; enhanced search indexing. Although the idea of such markup is hardly new, effective techniques for creating and manipulating it are more difficult than it appears. Since the structures and tokens in the two formats often do not correspond one-to-one, decisions and heuristics must be developed to determine in which way each component refers to and is referred to by components of the other representation. Conversion between fine and coarse-grained parallel markup complicates XML identifier (ID) assignments. In this paper, we will describe the techniques developed for LATEXML, a TEX/LATEX to XML converter, to create cross-referenced parallel MATHML. While not yet considering LATEXML's content MATHMLto be truly useful, the current effort is a step towards that continuing goal.

AB One initial goal for the DRMF is to seed our digital compendium with fundamental orthogonal polynomial formulae. We had used the data from the NIST Digital Library of Mathematical Functions (DLMF) as initial seed for our DRMF project. The DLMF input LATEX source already contains some semantic information encoded using a highly customized set of semantic LATEX macros. Those macros could be converted to content MATHML using LATEXML. During that conversion the semantics were translated to an implicit DLMF content dictionary. This year, we have developed a semantic enrichment process whose goal is to infer semantic information from generic LATEX sources. The generated context-free semantic information is used to build DRMF formula home pages for each individual formula. We demonstrate this process using selected chapters from the book "Hypergeometric Orthogonal Polynomials and their q-Analogues" (2010) by Koekoek, Lesky and Swarttouw (KLS) as well as an actively maintained addendum to this book by Koornwinder (KLSadd). The generic input KLS and KLSadd LATEX sources describe the printed representation of the formulae, but does not contain explicit semantic information. See http://drmf.wmflabs.org.

AB New particle formation (NPF) is an important atmospheric phenomenon. During an NPF event, particles first form by nucleation and then grow further in size. The growth step is crucial because it controls the number of particles that can become cloud condensation nuclei. Among various physical and chemical processes contributing to particle growth, condensation by organic vapors has been suggested as important. In order to better understand the influence of biogenic emissions on particle growth, we carried out modeling studies of NPF events during the BEACHON-ROCS (Biohydro-atmosphere interactions of Energy, Aerosol, Carbon, H2O, Organics & Nitrogen - Rocky Mountain Organic Carbon Study) campaign at Manitou Experimental Forest Observatory in Colorado, USA. The site is representative of the semi-arid western USA. With the latest Criegee intermediate reaction rates implemented in the chemistry scheme, the model underestimates sulfuric acid concentration by 50 %, suggesting either missing sources of atmospheric sulfuric acid or an overestimated sink term. The results emphasize the contribution from biogenic volatile organic compound emissions to particle growth by demonstrating the effects of the oxidation products of monoterpenes and 2-Methyl-3-buten-2-ol (MBO). Monoterpene oxidation products are shown to influence the nighttime particle loadings significantly, while their concentrations are insufficient to grow the particles during the day. The growth of ultrafine particles in the daytime appears to be closely related to the OH oxidation products of MBO.

AB Ozone holds a certain fascination in atmospheric science. It is ubiquitous in the atmosphere, central to tropospheric oxidation chemistry, yet harmful to human and ecosystem health as well as being an important greenhouse gas. It is not emitted into the atmosphere but is a byproduct of the very oxidation chemistry it largely initiates. Much effort is focused on the reduction of surface levels of ozone owing to its health and vegetation impacts, but recent efforts to achieve reductions in exposure at a country scale have proved difficult to achieve owing to increases in background ozone at the zonal hemispheric scale. There is also a growing realisation that the role of ozone as a short-lived climate pollutant could be important in integrated air quality climate change mitigation. This review examines current understanding of the processes regulating tropospheric ozone at global to local scales from both measurements and models. It takes the view that knowledge across the scales is important for dealing with air quality and climate change in a synergistic manner. The review shows that there remain a number of clear challenges for ozone such as explaining surface trends, incorporating new chemical understanding, ozone-climate coupling, and a better assessment of impacts. There is a clear and present need to treat ozone across the range of scales, a transboundary issue, but with an emphasis on the hemispheric scales. New observational opportunities are offered both by satellites and small sensors that bridge the scales.

AB Polyelectrolyte membranes (PEMs) have been employed as solid electrolytes in fuel-cell technologies as early as the 1950s, when they were used in NASA's Gemini program. However, PEM materials have only gained wide-spread attention in the last two decades due to advancements in membrane electrode-assembly (MEA) formation and the synthesis of new and interesting materials. Over the past several decades, various neutron techniques have played an instrumental role in measuring the structure and transport properties of PEMs in order to develop a deeper understanding of structure-property and performance relationships in PEM materials for fuel-cell applications.
