TI Transmission of a turbulent boundary layer wall pressure field through
an elastomeric coating
SO OCEAN ENGINEERING
LA English
DT Article
DE Flow noise; Turbulent boundary layer; SONAR
ID RESOLUTION; FLOW
AB The wall pressure fluctuations beneath a turbulent boundary layer introduce flow-induced noise and vibration which limits the performance of acoustic arrays. One method for mechanically filtering this energy is to separate the acoustic sensors from the fluid-solid interface with an elastomeric coating. Long wavelength acoustic energy is transmitted across the coating, and shorter wavelength energy from convected turbulence is attenuated. Experiments were conducted in an acoustically quiet water tunnel to measure the wall pressure fluctuations under 0.635 mm and 1.27 mm thick elastomeric coatings. Autospectra, magnitude and phase of the coherence, and convection velocities are presented for the range of Reynolds numbers 7540 < Re-0 < 16,100. The autospectra display an exponential decay which increases with increasing frequency and coating thickness. A modified model of that given by Blake (1984) is shown to accurately predict the attenuations in the autospectra. The cross-spectral model given by Corcos (1963) is shown to be valid for measurements of the wall pressure coherence beneath the coatings. Published by Elsevier Ltd.

AB A 23-year-old female with an 18-month history of left anterolateral thigh paresthesias and burning pain consistent with meralgia paresthetica was referred to our clinic after failing trials of physical therapy, nonsteroidal anti-inflammatories, gabapentin, and amitriptyline. We performed 3 lateral femoral cutaneous nerve blocks with corticosteroid over a 4-month period; however, each block provided only temporary relief. As this pain was limiting the patients ability to perform her functions as an active duty service member, we elected to perform a pulsed radiofrequency treatment of the lateral femoral cutaneous nerve with ultrasound guidance and nerve stimulation. After locating the lateral femoral cutaneous nerve with ultrasound and reproducing the patients dysthesia with stimulation, pulsed radiofrequency treatment was performed at 42 degrees C for 120 seconds. The needle was then rotated 180 degrees and an additional cycle of pulsed radiofrequency treatment was performed followed by injection of 0.25% ropivacaine with 4 mg of dexamethasone. At 1.5 and 3 month follow-up visits, the patient reported excellent pain relief with activity and improved ability to perform her duties as an active duty service member. ?

ID GALACTIC COSMIC-RAYS; RX J1713.7-3946; EMISSION; HAZE
AB Recently the Fermi-LAT data have revealed two gamma-ray emitting bubble-shaped structures at the Galactic center. If the observed gamma rays have hadronic origin (collisions of accelerated protons), the bubbles must emit high energy neutrinos as well. This new, Galactic, neutrino flux should trace the gamma-ray emission in spectrum and spatial extent. Its highest energy part, above 20-50 TeV, is observable at a kilometer-scale detector in the northern hemisphere, such as the planned KM3NeT, while interesting constraints on it could be obtained by the IceCube Neutrino Observatory at the South Pole. The detection or exclusion of neutrinos from the Fermi bubbles will discriminate between hadronic and leptonic models, thus bringing unique information on the still mysterious origin of these objects and on the time scale of their formation.

SO ANTIMICROBIAL AGENTS AND CHEMOTHERAPY

REGIMEN; MAMMALS; LAWS
AB My general pharmacokinetic scaling theory is discussed for the important matter of determining pediatric dosing for existing and new therapeutic drugs when optimal, or near-optimal, dosing for adults is known. The basis for the scaling is the requirement of a time-scaled likeness of the free-drug concentration time histories of children and adults. Broad categories of single and periodic dosing are considered. The former involves the scaling of dosage, and the latter involves both the dosage and schedule. The validity of the scaling relations is demonstrated by using measurements from previously reported clinical trials with adults and children (with ages generally 1 year or older) for the relatively new anti fungal agent caspofungin and for the relatively new antibacterial agent linezolid. Standard pharmacodynamic effectiveness criteria are shown to be satisfied for the scaled dosage and schedule for children to the same extent that they are for the referenced adult. Consideration of scaling from adults to children is discussed for the case of new agents where no pediatric data are available and needed parameters are determined from in vitro measurements and preclinical animal data. A connection is also made between the allometric representation of clearance data and the dosing formulas. Limitations of the scaling results for infants because of growth and maturational matters are discussed. The general conclusion from this work is that the scaling theory does indeed have application to pediatric dosing for children, for both confirmation and refinement of present practice and guidance in pediatric treatment with new therapeutic agents.

TI Modeling Peripheral Vision for Moving Target Search and Detection
SO AVIATION SPACE AND ENVIRONMENTAL MEDICINE
LA English
DT Article
DE peripheral vision; target detection; recognition; search and target
acquisition
ID SCENE PERCEPTION; VISUAL-ATTENTION; EYE-MOVEMENTS; ECCENTRICITY
AB Introduction: Most target search and detection models focus on foveal vision. In reality, peripheral vision plays a significant role, especially in detecting moving objects. Methods: There were 23 subjects who participated in experiments simulating target detection tasks in urban and rural environments while their gaze parameters were tracked. Button responses associated with foveal object and peripheral object (PO) detection and recognition were recorded. In an urban scenario, pedestrians appearing in the periphery holding guns were threats and pedestrians with empty hands were non-threats. In a rural scenario, non-U.S. unmanned aerial vehicles (UAVs) were considered threats and U.S. UAVs non-threats. Results: On average, subjects missed detecting 2.48 POs among 50 POs in the urban scenario and 5.39 POs in the rural scenario. Both saccade reaction time and button reaction time can be predicted by peripheral angle and entrance speed of POs. Fast moving objects were detected faster than slower objects and POs appearing at wider angles took longer to detect than those closer to the gaze center. A second-order mixed-effect model was applied to provide each subject's prediction model for peripheral target detection performance as a function of eccentricity angle and speed. About half the subjects used active search patterns while the other half used passive search patterns. Discussion: An interactive 3-D visualization tool was developed to provide a representation of macro-scale head and gaze movement in the search and target detection task. An experimentally validated stochastic model of peripheral vision in realistic target detection scenarios was developed.

TI Sensitivity of the Saline Load Test With and Without Methylene Blue Dye
in the Diagnosis of Artificial Traumatic Knee Arthrotomies
SO JOURNAL OF ORTHOPAEDIC TRAUMA
LA English
DT Article
DE knee arthrotomy; saline load test; methylene blue dye
ID MANAGEMENT; INJURIES; VOLUME; JOINT
AB Objectives: To determine whether methylene blue dye significantly improves the sensitivity of the saline load test for detection of a traumatic arthrotomy of the knee.
Design: Randomized, prospective.
Setting: Orthopaedic department, tertiary care medical center.
Patients/Participants: Subjects scheduled for elective outpatient knee arthroscopy were prospectively enrolled and randomized to a normal saline group or a methylene blue group. A total of 58 subjects were enrolled (methylene blue 29, normal saline 29).
Intervention: In the course of routine elective knee arthroscopy, a standard inferior lateral arthrotomy was created and then normal saline or methylene blue solution was injected while observing for fluid outflow from the arthrotomy site.
Main Outcome Measurements: The volume of fluid injected at the time of outflow was recorded with 180 mL set as the maximum injection volume.
Results: The false-negative rate was 67% (methylene blue 69%, normal saline 66%). In patients with a positive test, mean volume of injected fluid at outflow was 105 mL in the methylene blue group and 95 mL in the normal saline group (P = 0.61).
Conclusions: The sensitivity of the saline load test is unacceptably low. The addition of methylene blue does not improve the diagnostic value of the saline load test. Therefore, these results indicate that the saline load test, regardless of the inclusion of methylene blue, is not an accurate test for diagnosing small traumatic knee arthrotomies.

AB Background: Surgical site infections (SSIs) contribute significantly to patient morbidity and mortality and exhaust health care system resources. The main objectives of the study were to describe the incidence rates of SSIs among patients undergoing urologic or cardiothoracic surgeries, the associated risk factors, and the common causative etiologies found at Alexandria University Hospital in Egypt.
Methods: A prospective active surveillance study for patients undergoing urologic and cardiothoracic surgeries was implemented from July 2009 to December 2010. Patients were inspected daily for developing SSIs and with a 30-day postoperative follow-up. Wound swabs were obtained from patients who had clinical signs suggestive of infection. Swabs were cultured for bacterial identification and tested for antimicrobial sensitivity. Standard Centers for Disease Control and Prevention National Health Safety Network case definitions were used.
Results: SSIs occurred in 187 (17%) of patients with complete follow-up (n = 1,062), of which 106 (57%) occurred in-hospital and 81 (43%) occurred after discharge. Higher SSI rates were observed in cardiothoracic surgeries (23.3%), compared with urologic surgeries (9%) (P < .001). A stepwise logistic model identified an increased risk of SSI for those who underwent cardiothoracic surgeries (odds ratio [OR], 4.7; 95% confidence interval [CI], 2.2-11.1), those aged >45 years (OR, 2.32; 95% CI, 1.35-4.01), increased duration of hospital stay before (OR, 1.03; 95% CI, 1.01-1.05) and after (OR, 1.07; 95% CI, 1.04-1.09) surgery, antibiotics <= 24 hours before surgery (OR, 2.54; 95% CI, 1.63-3.94), and dirty wounds (OR, 4.09; 95% CI, 1.60-10.43).
Conclusions: Measures to reduce the high rates of SSI need to be instituted through a multidisciplinary effort including infection control education and specific SSI prevention activities at Alexandria University Hospital.

AB OBJECTIVE. Prior research indicates CT colonography (CTC) would be a cost-effective colorectal cancer (CRC) screening test if widespread availability were to increase overall CRC screening adherence rates. The primary aims of this multicenter study were to evaluate patient experience and satisfaction with CTC screening and compare preference against screening colonoscopy.
MATERIALS AND METHODS. A 12-question survey instrument measuring pretest choice, experience, and satisfaction was given to a consecutive cohort of adults undergoing CTC screening in three disparate screening settings: university academic center, military medical center, and community practice. The study cohort was composed of individuals voluntarily participating in clinical CTC screening programs.
RESULTS. A total of 1417 patients responded to the survey. The top reasons for choosing CTC for screening included "noninvasiveness" (68.0%), "avoidance of sedation/anesthesia" (63.1%), "ability to drive after the test" (49.2%), "avoidance of optical colonoscopy risks" (46.9%), and "identifying abnormalities outside the colon" (43.3%). Only 7.2% of patients reported pain during the CTC examination and only 2.5% reported greater than moderate discomfort. Of 441 patients who had experienced both CTC and optical colonoscopy, 77.1% preferred CTC and 13.8% preferred optical colonoscopy. Of all patients, 29.6% indicated that they may not have undergone optical colonoscopy screening if CTC were not available. Of all patients, 92.9% labeled their overall experience with CTC as "excellent" or "good," and 93.0% indicated they would choose CTC for their next screening.
CONCLUSION. Respondents reported a very high satisfaction level with CTC, and those who had experienced both modalities indicated a preference for CTC over optical colonoscopy. These results suggest that CTC has the potential to increase adherence to CRC screening guidelines if widely available.

AB The blazarAO 0235+164 (z=0.94) has been one of the most active objects observed by Fermi Large Area Telescope (LAT) since its launch in Summer 2008. In addition to the continuous coverage by Fermi, contemporaneous observations were carried out from the radio to gamma-ray bands between 2008 September and 2009 February. In this paper, we summarize the rich multi-wavelength data collected during the campaign (including F-GAMMA, GASP-WEBT, Kanata, OVRO, RXTE, SMARTS, Swift, and other instruments), examine the cross-correlation between the light curves measured in the different energy bands, and interpret the resulting spectral energy distributions in the context of well-known blazar emission models. We find that the gamma-ray activity is well correlated with a series of near-IR/optical flares, accompanied by an increase in the optical polarization degree. On the other hand, the X-ray light curve shows a distinct 20 day high state of unusually soft spectrum, which does not match the extrapolation of the optical/UV synchrotron spectrum. We tentatively interpret this feature as the bulk Compton emission by cold electrons contained in the jet, which requires an accretion disk corona with an effective covering factor of 19% at a distance of 100 R-g. We model the broadband spectra with a leptonic model with external radiation dominated by the infrared emission from the dusty torus.

AB Fermi has provided the largest sample of gamma-ray-selected blazars to date. In this work we use a complete sample of flat spectrum radio quasars (FSRQs) detected during the first year of operation to determine the luminosity function (LF) and its evolution with cosmic time. The number density of FSRQs grows dramatically up to redshift similar to 0.5-2.0 and declines thereafter. The redshift of the peak in the density is luminosity dependent, with more luminous sources peaking at earlier times; thus the LF of gamma-ray FSRQs follows a luminosity-dependent density evolution similar to that of radio-quiet active galactic nuclei. Also, using data from the Swift Burst Alert Telescope we derive the average spectral energy distribution (SED) of FSRQs in the 10 keV-300 GeV band and show that there is no correlation between the luminosity at the peak of the gamma-ray emission component and its peak frequency. Using this luminosity-independent SED with the derived LF allows us to predict that the contribution of FSRQs to the Fermi isotropic gamma-ray background is 9.3(-1.0)(+1.6)% (+/-3% systematic uncertainty) in the 0.1-100 GeV band. Finally we determine the LF of unbeamed FSRQs, finding that FSRQs have an average Lorentz factor of gamma = 11.7(-2.2)(+3.3), that most are seen within 5 degrees of the jet axis, and that they represent only similar to 0.1% of the parent population.

AB We present Spitzer Infrared Spectrograph observations of the ultraluminous X-ray source (ULX) NGC 6946 X-1 and its associated nebula MF 16. This ULX has very similar properties to the famous Holmberg II ULX, the first ULX to show a prominent infrared [O IV] emission line comparable to those found in active galactic nuclei. This paper attempts to constrain the ULX spectral energy distribution (SED) given the optical/UV photometric fluxes and high-resolution X-ray observations. Specifically, Chandra X-ray data and published Hubble optical/UV data are extrapolated to produce a model for the full optical to X-ray SED. The photoionization modeling of the IR lines and ratios is then used to test different accretion spectral models. While either an irradiated disk model or an O-supergiant plus accretion disk model fits the data very well, we prefer the latter because it fits the nebular parameters slightly better. In this second case the accretion disk alone dominates the extreme-UV and X-ray emission, while an O-supergiant is responsible for most of the far-UV emission.

AB The dynamics of mixed nested cylindrical wire arrays were studied at the UNR Zebra generator with our existing theoretical and experimental tools to better understand the contributions of each array to the emitted radiation. In particular, experimental results of mixed brass (70% Cu, 30% Zn) and Al (5056, 5% Mg) nested cylindrical wire arrays are analyzed and compared. The loads used brass in the inner array and Al in the outer array, or alternately, Al in the inner array and brass in the outer array, with a mass ratio of 1:1 (outer to inner). Consequently, radiative properties of K-shell Al and Mg ions and L-shell Cu and Zn ions are compared as functions of the placements of the brass and Al wires on the inner and outer arrays. Results show that the placement of brass and Al, whether on the inner or outer array, dramatically affects the intensity of the X-ray emission. Specifically, the ratio of Cu L-shell to Al K-shell emissions changed from 4 when Al is in the outer array to 40 when brass is in the outer array, and the total radiated yield was highest when the brass was on the outer array (18 kJ, versus 15 kJ when brass is on the inner array). Each load was fielded twice to vary the timing of the time-gated imaging and spectral diagnostics. This provides a more complete understanding of the evolution of the plasma parameters over the X-ray pulse and highlights the importance of the time-gated diagnostics. (C) 2012 Elsevier B.V.

AB This study presents a novel computer-assisted detection (CAD) system for automatically detecting and precisely quantifying abnormal nodular branching opacities in chest computed tomography (CT), termed tree-in-bud (TIB) opacities by radiology literature. The developed CAD system in this study is based on 1) fast localization of candidate imaging patterns using local scale information of the images, and 2) Mobius invariant feature extraction method based on learned local shape and texture properties of TIB patterns. For fast localization of candidate imaging patterns, we use ball-scale filtering and, based on the observation of the pattern of interest, a suitable scale selection is used to retain only small size patterns. Once candidate abnormality patterns are identified, we extract proposed shape features from regions where at least one candidate pattern occupies. The comparative evaluation of the proposed method with commonly used CAD methods is presented with a dataset of 60 chest CTs (laboratory confirmed 39 viral bronchiolitis human parainfluenza CTs and 21 normal chest CTs). The quantitative results are presented as the area under the receiver operator characteristics curves and a computer score (volume affected by TIB) provided as an output of the CAD system. In addition, a visual grading scheme is applied to the patient data by three well-trained radiologists. Interobserver and observer-computer agreements are obtained by the relevant statistical methods over different lung zones. Experimental results demonstrate that the proposed CAD system can achieve high detection rates with an overall accuracy of 90.96%. Moreover, correlations of observer-observer (R-2 = 0.8848, p < 0.01) and observer-CAD agreements (R-2 = 0.824, p < 0.01) validate the feasibility of the use of the proposed CAD system in detecting and quantifying TIB patterns.

AB This paper presents a technique for noise and vibration reduction in low-speed sensorless control algorithm of surface mounted permanent magnet synchronous machines (SM-PMSM). The signal processing involved in high-frequency-based sensorless control algorithms has a significant effect on the vibration and noise accompanying such algorithms. Therefore, a wavelet filtering approach is proposed. This wavelet filter is capable of extracting the position information even at low values of injection voltage amplitude where conventional filters fail to extract the information. This leads to a reduction in the machine's noise and vibration. Furthermore, an optimization using hardware-in-the-loop method based on genetic algorithms was implemented in real time to obtain the optimum value of the injected voltages amplitude and frequency causing the least possible vibration with acceptable position estimation accuracy. Consequently, a significant reduction in vibration and noise was achieved. The proposed techniques were implemented on a 2-hp SM-PMSM motor both experimentally and through simulations. Comparisons between numerical and test results confirm the validity of the proposed techniques.

DE Bent and negabent functions; Hadamard and nega-Hadamard transforms
ID BOOLEAN FUNCTIONS; POLYNOMIALS; CRITERIA
AB Parker et al. considered a new type of discrete Fourier transform, called nega-Hadamard transform. We prove several results regarding its behavior on combinations of Boolean functions and use this theory to derive several results on negabentness (that is, flat nega-spectrum) of concatenations, and partially symmetric functions. We derive the upper bound inverted right perpendicular n/2 inverted left perpendicular for the algebraic degree of a negabent function on n variables. Further, a characterization of bent-negabent functions is obtained within a subclass of the Maiorana-McFarland set. We develop a technique to construct bent-negabent Boolean functions by using complete mapping polynomials. Using this technique, we demonstrate that for each l >= 2, there exist bent-negabent functions on n = 12l variables with algebraic degree n/4 + 1 = 3l + 1. It is also demonstrated that there exist bent-negabent functions on eight variables with algebraic degrees 2, 3, and 4. Simple proofs of several previously known facts are obtained as immediate consequences of our work.

AB Objective: To model typical trajectories for improvement among patients treated in an integrated primary care behavioral health service, multilevel models were used to explore the relationship between baseline mental health impairment level and eventual mental health functioning across follow-up appointments. Method: Data from 495 primary care patients (61.1% female, 60.7% Caucasian, 37.141 +/- 12.21 years of age) who completed the Behavioral Health Measure (Kopta & Lowry, 2002) at each primary care appointment were used for the analysis. Three separate models were constructed to identify clinical improvement in terms of number of appointments attended, baseline impairment severity level, and the interaction of these 2 variables. Results: The data showed that 71.5% of patients improved across appointments, 56.8% of which (40.5% of the entire sample) was clinically meaningful and reliable. Number of appointments and baseline severity of impairment significantly accounted for variability in clinical outcome, with trajectories of change varying across appointments as a function of baseline severity. Patients with more severe impairment at baseline improved faster than patients with less severe baseline impairment. Conclusions: Patients treated within an integrated primary care behavioral health service demonstrate significant improvements in clinical status, even those with the most severe levels of distress at baseline.

AB Case study inverse thermal analyses of A12139 laser welds are presented. These analyses employ a numerical methodology that is in terms of analytic and numerical basis functions for inverse thermal analysis of steady state energy deposition in plate structures. The results of the case studies presented provide parametric representations of weld temperature histories that can be adopted as input data to various types of computational procedures, such as those for prediction of solid-state phase transformations and their associated software implementations. In addition, these weld temperature histories will be useful for construction of numerical basis functions that can be adopted for inverse analysis of welds corresponding to other process parameters or welding processes whose process conditions are within similar regimes.

AB Aluminum-magnesium alloys are ideal for ship construction; however, these alloys can become sensitized and susceptible to intergranular corrosion when exposed to moderately elevated temperatures. A stabilization treatment has been developed to reverse sensitization and restore corrosion resistance such that in-service plate can be refurbished rather than replaced. This treatment involves a short exposure to a specific elevated temperature range and can be implemented with portable units onboard a ship.

AB Antimicrobial peptides (AMPs) have recently gained attention as potentially valuable diagnostic and therapeutic agents. The utilization of these peptides for diagnostic purposes relies on the ability to immobilize them on the surface of a detection platform in a predictable and reliable manner that facilitates target binding. The method for attachment of peptides to a solid support is guided by peptide length, amino acid composition, secondary structure, and the nature of the underlying substrate. While immobilization methods that target amine groups of amino acid sequences are widely used, they can result in heterogeneous conjugation at multiple sites on a peptide and have direct implications for peptide presentation and function. Using two types of commercial amine-reactive microtiter plates, we described the effects of analogous immobilization chemistries on the surface attachment of AMPs and their differential binding interaction with Gram-specific bacterial biomarkers, lipopolysaccharide and lipoteichoic acid. As might be expected, differences in overall binding affinities were noted when comparing AMPs immobilized on the two types of plates. However, the two-amine-targeted linking chemistries also affected the specificity of the attached peptides; lipopolysaccharide generally demonstrated a preference for peptides immobilized on one type of plate, while (when observed at all) lipoteichoic acid bound preferentially to AMPs immobilized on the other type of plate. These results demonstrate the potential for tuning not only the binding affinities but also the specificities of immobilized AMPs by simple alterations in linking strategy. Published 2012.

AB Both awe and envy are emotions that can result from observing a powerful other, but awe should stabilize social hierarchies while envy should undermine them. Three studies explored how the physiological reaction of goose bumps might help in understanding these distinctive reactions to powerful others, as goose bumps should be associated with awe rather than envy. In Study 1, participants kept a four-week journal and made a detailed entry each time they experienced goose bumps. Goose bumps resulting from the emotion of awe were the second most frequently occurring type after reactions to cold. Consistent with understanding awe as an emotional reaction to powerful or superior others (Keltner and Haidt in Cogn Emot 17:297-314, 2003), many of these experiences had social triggers. In Study 2, accounts of goose bumps resulting from exposure to powerful or superior others contained greater awe than envy. Also, the intensity of goose bumps was positively correlated with awe and negatively correlated with envy. In Study 3, accounts of awe contained more goose bumps than accounts of envy, and goose bumps were positively correlated with awe.

We find that, for illumination at 633 nm, the quantum efficiency of the photodarkening process is of about 4% and that the absorption cross-section of the dark centers is similar to 2.2 times larger than that of the intrinsic structural units. The insights gained from the modeling are compared with the experimental results obtained when writing Bragg gratings using 633 nm, 594 nm and 568 nm laser light. (C) 2012 Elsevier B.V.

AB As of April 2010, all maternity care at government healthcare facilities in Sierra Leone is provided at no cost to patients. In late 2010, we conducted a community health census of 18 sections of the city of Bo (selected via randomized cluster sampling from 68 total sections). Among the 3421 women with a history of pregnancy who participated in the study, older women most often reported having a history of both home and hospital deliveries, while younger women showed a preference for hospital births. The proportion of lastborn children delivered at a healthcare facility increased from 71.8% of offspring 1014 years old to 81.1% of those one to nine years old and 87.3% of infants born after April 2010. These findings suggest that the new maternal healthcare initiative has accelerated an existing trend toward a preference for healthcare facility births, at least in some urban parts of Sierra Leone.

AB Objective: To determine whether a weighted versus unweighted balloon catheter achieved a shorter first stage of labor. Methods: This was a randomized trial of patients undergoing induction with Bishop score <4. Women were randomized to weighted balloon catheter with 1000 mL fluid bag or unweighted catheter taped to the thigh. Results: A total of 60 women were randomized. The time from balloon catheter insertion until discontinuation was significantly longer in the unweighted group 4.62 +/- 0.65 h versus 1.59 +/- 0.2 h in the weighted group (p = 0.001). This resulted in longer cervical ripening/first stage of labor in the unweighted (18.52 +/- 0.96 h) versus weighted group (15.3 +/- 0.99 h) (p = 0.025). The unweighted balloon catheter had a shorter first stage of labor as gravidity increased (p = 0.007) and as race went from white to non-white (p = 0.003). There was no difference in perceived pain after balloon insertion (p = 0.0942), or Bishop score after balloon discontinuation (p = 0.1661). Conclusion: The total time from cervical ripening to the end of the first stage of labor is significantly shortened with the weighted balloon catheter.

AB Background: The well-described biologic and epidemiologic associations of syphilis and HIV are particularly relevant to the military, as service members are young and at risk for sexually transmitted infections. We therefore used the results of serial serologic testing to determine the prevalence, incidence, and risk factors for incident syphilis in a cohort of HIV-infected Department of Defense beneficiaries.
Methods: Participants with a positive nontreponemal test at HIV diagnosis that was confirmed on treponemal testing were categorized as prevalent cases, and participants with an initial negative nontreponemal test who subsequently developed a confirmed positive nontreponemal test were categorized as incident cases.
Results: At HIV diagnosis, the prevalence of syphilis was 5.8% (n = 202). A total of 4239 participants contributed 27,192 person-years (PY) to the incidence analysis and 347 (8%) developed syphilis (rate, 1.3/100 PY; [1.1, 1.4]). Syphilis incidence was highest during the calendar years 2006 to 2009 (2.5/100 PY; [2.0, 2.9]). In multivariate analyses, younger age (per 10 year increase hazard ratio [HR], 0.8; [0.8-0.9]), male gender (HR, 5.6; [2.3-13.7]), non-European-American ethnicity (African-American HR, 3.2; [2.5-4.2]; Hispanic HR, 1.9; [1.2-3.0]), and history of hepatitis B (HR, 1.5; [1.2-1.9]) or gonorrhea (HR, 1.4; [1.1-1.8]) were associated with syphilis.
Conclusions: The significant burden of disease both at and after HIV diagnosis, observed in this cohort, suggests that the cost-effectiveness of extending syphilis screening to at-risk military members should be assessed. In addition, HIV-infected persons continue to acquire syphilis, emphasizing the continued importance of prevention for positive programs.

AB Objectives To investigate the epidemiology and risk factors of gonorrhoea (GC) or chlamydia (CT) coinfection in an HIV-positive US military cohort, focusing on the time after participants' knowledge of HIV diagnosis.
Methods The authors analysed data from 4461 participants enrolled in the US Military Natural History Study cohort for GC or CT infection >= 6 months after their HIV-positive test.
Results During a mean follow-up of 7.08 years, 482 (11%) participants acquired a GC or CT infection. Of these, 283 (6%) acquired a GC infection, 278 (6%) acquired a CT infection and 123 (3%) had multiple GC or CT infections during follow-up. Risk of GC or CT infection was significantly greater in those younger, male, African-American and with a history of GC or CT infection.
Conclusions Frequent GC and CT diagnoses observed among members of this HIV-positive cohort indicate substantial ongoing risk behaviours that raise concerns for HIV transmission and underscore the need for continued screening to help identify and treat these sexually transmitted infections in this population.

AB Rapid presymptomatic diagnosis of Bacillus anthracis at early stages of infection plays a crucial role in prompt medical intervention to prevent rapid disease progression and accumulation of lethal levels of toxin. To detect low levels of the anthrax protective antigen (PA) exotoxin in biological fluids, we have developed a metal-enhanced fluorescence (MEF)-PA assay using a combination of the MEF effect and microwave-accelerated PA protein surface absorption. The assay is based on a modified version of our "rapid catch and signal" (RCS) technology previously designed for the ultra-fast and sensitive analysis of genomic DNA sequences. Technologically, the proposed MEF-PA assay uses standard 96-well plastic plates modified with silver island films (SiFs) grown within the wells. It is shown that the fluorescent probe, covalently attached to the secondary antibody, plays a crucial role of indicating complex formation (i.e., shows a strong MEF response to the recognition event). Microwave irradiation rapidly accelerates PA deposition onto the surface ("rapid catch"), significantly speeding up the MEF-PA assay and resulting in a total assay run time of less than 40 min with an analytical sensitivity of less than 1 pg/ml PA.

DE Islam; Just war tradition; Liberalism; Sharia; Religious war
AB Most contemporary advocates of the Just War Tradition (JWT) condemn religious war. If they are correct, waging war should be a secular affair, fully justifiable on non-religious grounds. This secularized understanding of the JWT draws on normative commitments that lead many political theorists to advocate in favor of a secularized politics in western liberal polities. As a matter of historical fact and contemporary commitment, many Muslims have rejected the secularized conception of the morality of war found in contemporary conceptions of the JWT. I argue that, given appropriate distinctions between relevantly different kinds of religious war, advocates of the JWT have excellent reason to rethink their antipathy to religious war. Specifically, I argue that distinct kinds of religious war can enjoy differential normative standing and that there is no compelling reason to believe that religiously justified wars must be waged in a morally improper manner, viz., in a way that violates the JWT's requirements.

AB The quantum theoretical concepts of modular momentum and dynamical non-locality, which were introduced four decades ago, have recently been used to explain single particle quantum interference phenomena. Although the non-local exchange of modular momentum associated with such phenomena cannot be directly observed, it has been suggested that effects induced by this exchange can be measured experimentally using weak measurements of pre- and post-selected ensembles of particles. This paper reports on such an optical experiment that yielded measured weak values that were consistent with the theoretical prediction of an effect induced by a non-local exchange of modular momentum.

AB Alloying Al with Mg can improve its structural properties but also can lead to the formation of grain-boundary precipitates of beta-Mg2Al3 that lead to failure by intergranular fracture and corrosion. Simulating the properties of the beta phase is difficult because it has a complex structure with more than 1000 atoms per unit cell. We approximate the experimental beta structure by the beta' structure, which has about 300 atoms per unit cell, and we compute the fracture behavior of the material from density functional theory calculations of relevant surface and interface energies. We report also on experimental measurements of the orientation and fracture properties of the alpha-Al(Mg)-beta-Mg2Al3 interface and compare them with the atomistic simulations. We have computed the surface energy of face-centered cubic alpha-Al with up to 10 at. pct Mg, as well as the decohesion energy of beta'-Mg2Al3 and the interfacial decohesion energy between beta'-Mg2Al3 and pure alpha-Al with geometry similar to that observed experimentally. We find that the beta'-Mg2Al3 decohesion energy is nearly isotropic and is lower than the pure Al surface energy and the alpha-Al-beta'-Mg2Al3 interface decohesion energy. This result is consistent with the experimental observations of fracture within the beta phase rather than at the alpha-Al(Mg)-beta-Mg2Al3 interface or within the alpha-Al(Mg) phase.

SO JOURNAL OF ENGINEERING FOR GAS TURBINES AND POWER-TRANSACTIONS OF THE
ASME
LA English
DT Article
ID METHODOLOGY
AB High-cycle fatigue (HCF) is arguably one of the costliest sources of in-service damage in military aircraft engines. HCF of turbine blades and disks can pose a significant engine risk because fatigue failure can result from resonant vibratory stresses sustained over a relatively short time. A common approach to mitigate HCF risk is to avoid dangerous resonant vibration modes (first bending and torsion modes, etc.) and instabilities (flutter and rotating stall) in the operating range. However, it might be impossible to avoid all the resonance for all flight conditions. In this paper, a methodology is presented to assess the influences of HCF loading on the fracture risk of gas turbine engine components subjected to fretting fatigue. The methodology is based on an integration of a global finite element analysis of the disk-blade assembly, numerical solution of the singular integral equations using the CAPRI (Contact Analysis for Profiles of Random Indenters) and Worst Case Fret methods, and risk assessment using the DARWIN (Design Assessment of Reliability with Inspection) probabilistic fracture mechanics code. The methodology is illustrated for an actual military engine disk under real life loading conditions. [DOI: 10.1115/1.4005975]

AB We have redesigned the air cathode for metal-air batteries by adapting fiber-paper-supported carbon nanofoams as the base electrode architecture. Electrocatalytic functionality for the oxygen reduction reaction (ORR) is added into the conductive, ultraporous nanofoam paper by electroless deposition at the carbon walls of conformal nanoscopic coatings of birnessite-like manganese oxide (10-20-nm thick MnOx) via redox reaction with aqueous permanganate (MnO4-). We report the ORR activity measured using an air-breathing electroanalytical cell for a series of native and MnOx-functionalized carbon nanofoams in which the size of the pore network is varied from tens to hundreds of nanometers, the thickness of the air cathode is varied, and the degree of hydrophilicity/hydrophobicity of the electrode structure is altered. Technologically relevant ORR activity is obtained at 0.9 V vs. Zn for MnOx-functionalized carbon nanofoams that are >= 180-mu m thick, have pores on the order of 100-200 nm, and are modified with hydrophobic poly(vinylidene difluoride).

AB Recent advances in computational materials science present novel opportunities for structure discovery and optimization, including uncovering of unsuspected compounds and metastable structures, electronic structure, surface, and nano-particle properties. The practical realization of these opportunities requires systematic generation and classification of the relevant computational data by high-throughput methods. In this paper we present AFLOW (Automatic Flow), a software framework for high-throughput calculation of crystal structure properties of alloys, intermetallics and inorganic compounds. The AFLOW software is available for the scientific community on the website of the materials research consortium, aflowlib.org. Its geometric and electronic structure analysis and manipulation tools are additionally available for online operation at the same website. The combination of automatic methods and user online interfaces provide a powerful tool for efficient quantum computational materials discovery and characterization. (C) 2012 Elsevier B.V.

AB In this paper, we examine the effects of aspect ratio and orientational order of nanoparticles on the dielectric properties of nanocomposites. The motivation is to clearly establish the effects of orientational order, since ambiguities exist in the literature. We focus on metallic nanoparticles, and show that, in the dilute concentration limit, theory, experiments and numerical simulations all unequivocally indicate that the effective dielectric constant increases with increasing aspect ratio and increasing degree of alignment of rod-like nanoparticles when they orient in direction of the electric field.

AB A one-dimensional model of an in vitro experiment, in which a specimen of cancellous bone is immersed in water and insonified by an ultrasonic pulse, is considered. The modification of the poroelastic model of Blot due to Johnson et al. [D.L. Johnson, J. Koplik, R. Dashen, Theory of dynamic permeability and tortuosity in fluid-saturated porous media, J. Fluid Mech. 176 (1987) 379-402] is used for the cancellous bone segment. By working with series expansions of the Laplace transform in terms of travel-time exponentials, a series of transfer functions for the reflection and transmission of fast and slow waves at the fluid-poroelastic interfaces are derived. The approach obviates numerical solution beyond the discretization involved in the use of the fast Fourier transform. (C) 2011 Published by Elsevier Ltd

AB We test the utility of the OII 83.4 nm emission feature as a measure of ionospheric parameters. Observed with the Remote Atmospheric and Ionospheric Detection System (RAIDS) Extreme Ultraviolet Spectrograph on the International Space Station (ISS), limb profiles of 83.4 nm emissions are compared to predicted dayglow emission profiles from a theoretical model incorporating ground-based electron density profiles measured by the Millstone Hill radar and parameterized by a best-fit Chapman-a function. Observations and models are compared for periods of conjunction between Millstone Hill and the RAIDS fields-of-view. These RAIDS observations show distinct differences in topside morphology between two days, 15 January and 10 March 2010, closely matching the forward model morphology and demonstrating that 83.4 nm emission is sensitive to changes in the ionospheric density profile from the 340 km altitude of the ISS during solar minimum. We find no significant difference between 83.4 nm emission profiles modeled assuming a constant scale height Chapman-a best-fit to the ISR measurements and those assuming varying scale height.

AB Zirconium hydroxide was evaluated for the ability to detoxify chemical warfare agents GD, HD, and VX. Observed half-lives were 8.7 min, 2.3 h, and 1 min, respectively. Owing to its extremely fast reaction rate, the mechanism for VX was further characterized. Zirconium hydroxide samples were calcined at temperatures ranging from 150 to 900. degrees C to investigate the effect of surface speciation on VX hydrolysis rates. NMR, TGA/DSC, TEM, and potentiometric tritration reveal the importance of the acidic, bridging OH groups of Zr(OH)(4) which are proposed to protonate and catalytically hydrolyze VX in a manner similar to autocatalysis by EMPA in solution.

AB We develop a set of laser rate equations that accurately describes mechanical amplification in optomechanical oscillators driven by photothermal or radiation pressure forces. In the process we introduce a set of parameters describing gain, stored energy, slope efficiency, and saturation power of the mechanical laser. We identify the three-phonon parametric interactions as a microscopic mechanism enabling self-oscillation. Our theory shows remarkable agreement with our experimental data, demonstrating that optomechanical self-oscillation is essentially a "phonon lasing'' process in which an optical pump generates coherent acoustic phonons.

AB There has been considerable interest in chemically functionalizing graphene films to control their electronic properties, to enhance their binding to other molecules for sensing, and to strengthen their interfaces with matrices in a composite material. Most reports to date have largely focused on noncovalent methods or the use of graphene oxide. Here, we present a method to activate CVD-grown graphene sheets using fluorination followed by reaction with ethylenediamine (EDA) to form covalent bonds. Reacted graphene was characterized via X-ray photoelectron spectroscopy (XPS), attenuated total reflectance Fourier transform infrared spectroscopy (ATR-FTIR), and Raman spectroscopy as well as measurements of electrical properties. The functionalization results in stable, densely packed layers, and the unbound amine of EDA was shown to be active toward subsequent chemical reactions.

AB The nonequilibrium absorption of longitudinal-optical phonons by hot electrons are studied in terahertz quantum cascade structures. We present a method for including electron leakage to the continuum that takes into account the mobility of the electrons. This is incorporated into a density matrix Monte Carlo method that includes the optical field within the resonant cavity. The effects of electron leakage to the continuum as a function of lattice temperature are discussed. Results are compared with experiment and found to be consistent. It is shown that using only confined wave functions and thereby neglecting the leakage via tunneling is inadequate for describing the electron transport.

AB Background: Irritable bowel syndrome (IBS) and inflammatory bowel disease (IBD) symptoms often overlap. In some IBS cases there are subtle inflammatory changes similar to the immune-mediated pathophysiology of IBD, and the risk of both increases after infectious gastroenteritis (IGE).
Methods: To evaluate the effect of IBS and IGE on IBD risk utilizing US Department of Defense medical encounter data, active duty personnel with IBS were matched to subjects without IBS. Medical encounter history was analyzed to assess for incident IBD. IGE was identified from documented medical encounters and by self-report. Relative risks were calculated using Poisson regression models.
Results: We identified 9,341 incident IBS cases and 18,678 matched non-IBS subjects and found an 8.6-fold higher incidence (p < 0.0001) of IBD among those with IBS (238.1 per 100,000 person-years) compared to our referent population (27.8 per 100,000 person-years). In a subset (n = 2,205) of well-defined IBS cases, IBD risk was 15 times that of subjects without IBS. The median time between IBS and IBD diagnoses was 2.1 years. IGE also increased IBD risk approximately 2-fold (p < 0.05) after controlling for IBS.
Conclusions: These data reflect a complex interaction between illness presentation and diagnosis of IBS and IBD and suggest intercurrent IGE may increase IBD risk in IBS patients. Additional studies are needed to determine whether IBS lies on the causal pathway for IBD or whether the two are on a pathophysiological spectrum of the same clinical illness. These data suggest consideration of risk reduction interventions for IGE among IBS patients at high disease risk.

AB Predicting water column integrated phytoplankton biomass from near-surface measurements has been an important effort in marine ecological research, particularly since the advent of satellite remote sensing of ocean color. Quantitative relationships between chlorophyll-a concentrations (Chl-a) at the surface and its depth-integrated magnitude have thus far only been developed for open-ocean waters. Here we develop and test for the first time an extension of open-ocean relationships into ocean-margin waters, specifically the highly productive and variable eastern boundary upwelling ecosystem off the central California coast. This region was chosen because of the unique availability of a 30-year record of ship-based Chl-a profiles measured using consistent methods. The extended relationship allows accurate prediction of integrated biomass from surface measurements. Further, we develop a new set of relationships for predicting the depth-integrated Chl-a from Chl-a measured over a range of discrete depths (i.e., as measured by fluorometers on moorings). The newly developed relationships are tested against 15,000 fluorometric Chl-a profiles obtained from an autonomous underwater vehicle. Surprisingly, the relationship between surface Chl-a and depth-integrated Chl-a holds for profiles with high concentrations of Chl-a in persistent subsurface thin phytoplankton layers (layers <3 m thick and located below the first optical depth). The results have implications for monitoring of algal blooms and for quantifying ocean primary productivity from satellite observations of ocean color.

AB Refractory metal cermets have attractive mechanical properties for high temperature applications, but exhibit poor resistance to oxidation attack. A two-step coating process has been developed in order to provide an effective high temperature oxidation resistance. W-HfN and Mo-ZrN cermet samples were initially coated with a layer of Mo through a Mo(CO)(6) decomposition reaction. The second step involved a co-deposition of B and Si by a pack cementation treatment. The resultant aluminoborosilicate coating exhibits good adherence to the cermet samples. Oxidation exposure at temperatures up to 1400 degrees C demonstrated minimal mass change and an unaltered cermet microstructure. (c) 2012 Elsevier B.V. All rights reserved.

SO GEOPHYSICAL RESEARCH LETTERS

ID RADIO-WAVES; LATITUDE IONOSPHERE
AB We present the results of numerical simulations of artificial ducts during high-power HF heating performed by a novel model accounting for the effect of self-action. This effect interferes with the HF-plasma matching in the heated region and hence with electron heating. The model satisfactorily explains recent experimental observations. It helps for choosing the heating parameters optimal for duct formation, such as proper duration of the heating pulse and its frequency. It also suggests that distortion of the ducts caused by the self-action effect can be avoided by down-chirping the heating frequency. The down-chirping rates needed to suppress such distortions are evaluated.

AB Background-Up to 25% of patients with untreated Kawasaki disease (KD) and 5% of those treated with intravenous immunoglobulin will develop coronary artery aneurysms. Persistent aneurysms may remain silent until later in life when myocardial ischemia can occur. We sought to determine the prevalence of coronary artery aneurysms suggesting a history of KD among young adults undergoing coronary angiography for evaluation of possible myocardial ischemia.
Methods and Results-We reviewed the medical histories and coronary angiograms of all adults <40 years of age who underwent coronary angiography for evaluation of suspected myocardial ischemia at 4 San Diego hospitals from 2005 to 2009 (n=261). History of KD-compatible illness and cardiac risk factors were obtained by medical record review. Angiograms were independently reviewed for the presence, size, and location of aneurysms and coronary artery disease by 2 cardiologists blinded to the history. Patients were evaluated for number of risk factors, angiographic appearance of their coronary arteries, and known history of KD. Of the 261 young adults who underwent angiography, 16 had coronary aneurysms. After all clinical criteria were assessed, 5.0% had aneurysms definitely (n=4) or presumed (n=9) secondary to KD as the cause of their coronary disease.
Conclusions-Coronary sequelae of KD are present in 5% of young adults evaluated by angiography for myocardial ischemia. Cardiologists should be aware of this special subset of patients who may benefit from medical and invasive management strategies that differ from the strategies used to treat atherosclerotic coronary artery disease.

SO APPLIED PHYSICS LETTERS

DT Article
ID V COMPOUND SEMICONDUCTORS; DIODES
AB Lattice matched InAlGaAs tunnel junctions with a 1.18 eV bandgap have been grown for a triple-junction solar cell on InP. By including two InGaAs quantum wells in the structure, a peak tunnel current density of 113 A/cm(2) was observed, 45 times greater than the baseline bulk InAlGaAs tunnel junction. The differential resistance of the quantum well device is 7.52 x 10(-4) Omega cm(2), a 15-fold improvement over the baseline device. The transmission loss to the bottom cell is estimated to be approximately 1.7% and a network simulation demonstrates that quantum well tunnel junctions play a key role in improving performance at high sun-concentrations.

AB A 4-electrode impedance-based microfluidic sensor was designed to achieve tunable sensitivity, while simultaneously decreasing the channel clogging and nonspecific binding that often adversely impact device function. Hydrodynamic focusing - a characteristic of laminar flow at low Reynolds number provides highly controllable sensitivity in impedance-based microfluidic biosensors, by creating a "virtual" microchannel with soft walls and adjustable dimensions. Enhanced sensitivity, limited nonspecific binding, and a reduction in microchannel clogging have been achieved using hydrodynamic focusing within a 250 mu m deep by 1 mm wide microchannel. The microfluidic sensor was able to detect microparticles as small as 5 mu m in diameter specifically bound between co-planar platinum micro-electrodes. However, detection of submicron particles and E. coli cells in similar fashion proved to be challenging. A theoretical analysis of forces exerted by the fluids within the microchannel allowed specification of flow rates amenable to decreased nonspecific binding of interfering cells or microparticles, while ensuring minimal disruption to specifically bound targets. Simulations revealed that complex flow behavior of the hydrodynamically focused streams around specifically bound micron-sized particles reduces sensitivity. An improved understanding is thus presented of the parameters that impact the sensitivity of impedance-based biosensors implementing hydrodynamic focusing and specific target binding.

AB Complementary metal-oxide semiconductor (CMOS)-hybrid arrays have become competitive optical detectors for use in ground-and space-based astronomy. Interpixel capacitance (IPC) is one source of error that appears in most CMOS arrays. In this paper, we use a single-pixel-reset method to model IPC. We combine this IPC model with a model for charge diffusion to estimate the total crosstalk on H4RG-10 arrays. Finally, we compare our model results to Fe-55 data obtained using an astrometric camera built to test the H4RG-10 B0 generation detectors. (C) 2012 Optical Society of America

AB A simple formalism to describe nonthermal electron acceleration, evolution, and radiation in supernova remnants (SNRs) is presented. The electron continuity equation is analytically solved assuming that the nonthermal electron injection power is proportional to the rate at which the kinetic energy of matter is swept up in an adiabatically expanding SNR shell. We apply this model to Fermi and HESS data from the SNR RX J1713.7-3946 and find that a one-zone leptonic model with Compton-scattered cosmic microwave background and interstellar infrared photons has difficulty providing a good fit to its spectral energy distribution, provided the source is at a distance similar to 1 kpc from the Earth. However, the inclusion of multiple zones, as hinted at by recent Chandra observations, does provide a good fit, but requires a second zone of compact knots with magnetic fields B similar to 16 mu G, comparable to shock-compressed fields found in the bulk of the remnant.

AB Wind stress over the ocean depends on the sea surface roughness which is determined by the sea state. On one hand, underdeveloped wind seas, rougher than their fully developed counterpart, increase the drag. On the other hand, the presence of swell can modify wind stress by modifying the wind sea roughness. This latter mechanism is believed to have a great impact at high winds whenever underdeveloped local waves coexist with swell. Detailed measurements of wind stress and wavefield in fetch-limited growth conditions were made in an area subjected to strong and persistent winds. Through the analysis of wavefield observations, it is found that the presence of swell dampens the short wind waves. The observed attenuation is greater for younger wind seas and decreases as the wind waves become older. Results obtained from modeling the interaction of wind waves and the air flow above point out that the attenuation of short wind waves causes a reduction of the wave-supported stress, which in turn decreases the total wind stress.

ID IONOSPHERIC SCINTILLATION; MORPHOLOGY; IRREGULARITIES; MISSION
AB We report observations of the L band scintillation climatology made during the minimum of solar cycle 23/24 using the Constellation Observing System for Meteorology, Ionosphere, and Climate (COSMIC, also known as FORMOSAT-3). The measurements of the S4 scintillation index were made using the GPS Occultation Experiment instrument, which is a dual-frequency GPS receiver used for routine ionospheric measurements via occultation of satellites in the GPS constellation. A method for geolocating the S4 measurements is presented and discussed. The geolocated COSMIC measurements are used to construct monthly climatologies of the S4 scintillation index, which are in good agreement with previous climatologies based on ground-based measurements. COSMIC measurements of the electron density and S4 index permit an assessment of the correlation of the S4 index with the electron density. The scintillation climatology for March and April 2007 is compared to the coincident monthly climatology of the electron density, and a correlation is observed, but this correlation does not appear to hold globally. The COSMIC measurements are shown to be a powerful data set for studying L band scintillation and its correlation with the underlying ionospheric morphology.

AB Solar radiation below similar to 100 nm produces photoelectrons, a substantial portion of the F region ionization, most of the E region ionization, and drives chemical reactions in the thermosphere. Unquantified uncertainties in thermospheric models exist because of uncertainties in solar irradiance models used to fill spectral and temporal gaps in solar irradiance observations. We investigate uncertainties in solar energy input to the thermosphere on solar rotation time scales using photoelectron observations from the FAST satellite. We compare observed and modeled photoelectron energy spectra using two photoelectron production codes driven by five different solar irradiance models. We observe about 1.7% of the ionizing solar irradiance power in the escaping photoelectron flux. Most of the code/model pairs used reproduce the average escaping photoelectron flux over a 109-day interval in late 2006. The code/model pairs we used do not completely reproduce the observed spectral and solar rotation variations in photoelectron power density. For the interval examined, 30% of the variability in photoelectron power density with equivalent wavelengths between 18 and 45 nm was not captured in the code/model pairs. For equivalent wavelengths below similar to 16 nm, most of the variability was missed. This result implies that thermospheric model runs based on the solar irradiance models we tested systematically underestimate the energy input from ionizing radiation on solar rotation time scales.

TI Searches for sterile neutrinos with IceCube DeepCore
SO PHYSICAL REVIEW D
LA English
DT Article
AB We show that study of the atmospheric neutrinos in the 10-100 GeV energy range by DeepCore subarray of the IceCube Neutrino Observatory can substantially constrain the mixing of sterile neutrinos of mass similar to 1 eV with active neutrinos. In the scheme with one sterile neutrino we calculate nu(mu) and (nu) over bar (mu) oscillation probabilities as well as zenith angle distributions of nu(CC)(mu) (charge current) events in different energy intervals in DeepCore. The distributions depend on the mass hierarchy of active neutrinos. Therefore, in principle, the hierarchy can be identified, if nu(s) exists. After a few years of exposure the DeepCore data will allow us to exclude the mixing of vertical bar U-mu 4 vertical bar(2) >= 0.02 indicated by the LSND/MiniBooNE results. Combination of the DeepCore and high-energy IceCube data will further improve sensitivity to nu(s) mixing parameters.

AB Armed conflicts have been prevalent throughout history, in some cases having very great consequences. To win, one needs to understand the characteristics of an armed conflict and be prepared with resources and capabilities for responding to its specific challenges. An important tool for understanding these characteristics and challenges is a model-an abstraction of the field of conflict. Models have evolved through the years, addressing different conflict scenarios with varying techniques.

AB Structural dynamics in the glassy state of two protic ionic liquids, carvedilol phosphate and procaine hydrochloride, were characterized from analysis of changes in the conductivity relaxation times during physical aging. The obtained a relaxation times, having a magnitude exceeding feasible experimental time scales and thus not directly measurable, are consistent with published data from a method that relies on the presence of a secondary relaxation. We also observe a narrowing of the relaxation dispersion, specific to higher frequencies, that is a consequence of the heterogeneous dynamics of deeply supercooled materials.

In sharp contrast with Si, kappa( T) of diamond nanowires as thick as 400 nm still increase monotonically with temperature up to 300 K, and room-temperature size effects are stronger than for Si. A marked dependence of kappa on the crystallographic orientation is predicted, which is apparent even at room temperature. [001] growth direction always possesses the largest. in diamond nanowires. The predicted features point to a potential use of diamond nanowires for the precise control of thermal flow in nanoscale devices.

TI Giant negative magnetoresistance and a transition from strong to weak
localization in hydrogenated graphene
SO PHYSICAL REVIEW B
LA English
DT Article
AB A giant negative magnetoresistance of up to 28% at 2.5 T is observed in plasma hydrogenated graphene at the charge neutrality point without any sign of saturation at 2.0 K. A detailed analysis of the gate voltage dependence demonstrates a suppression of the giant negative magnetoresistance, which is accompanied by a crossover from strong localization at low carrier concentrations to weak localization at higher carrier concentrations. Evidence of asymmetry in the electron/hole transport is found in themagnetic field traces at low temperature. The asymmetrical transport is attributed to charge transfer processes at the graphene/metal interface and demonstrates the effect of using invasive contact geometries in hydrogenated graphene devices.

AB We report measurements of the charge-separated W+(-)-> e(+(-))+nu(e)(nu-(e)) and Z/gamma*-> e(+)e(-) production cross sections at mid-rapidity in proton-proton collisions at root s=500 GeV. These results are based on 13.2 pb(-1) of data recorded in 2009 by the STAR detector at RHIC. Production cross sections for W bosons that decay via the e nu channel were measured to be sigma(pp -> W+X)center dot BR(W+-> e(+)nu e)=117.3 +/- 5.9(stat)+/- 6.2(syst)+/- 15.2(lumi) pb, and sigma(pp -> W-X)center dot BR(W--> e(-)(nu)over bar(-)e)=43.3 +/- 4.6(stat)+/- 3.4(syst)+/- 5.6(lumi) pb. For Z/gamma* production, sigma(pp -> Z/gamma*X)center dot BR(Z/gamma*-> e(+)e(-))=7.7 +/- 2.1(stat)-0.9+0.5(syst)+/- 1.0(lumi) pb was measured for di-lepton invariant masses m(e+e-) between 70 and 110 GeV/c(2). First measurements of the W cross section ratio, sigma(pp -> W+X)/sigma(pp -> W-X), at root v=500 GeV are also reported. Theoretical predictions, calculated using recent parton distribution functions, are found to agree with the measured cross sections.

TI Thoracic hyperextension injury with complete "bony disruption" of the
thoracic cage: Case report of a potentially life-threatening injury

AB Background: Severe chest wall injuries are potentially life-threatening injuries which require a standardized multidisciplinary management strategy for prevention of posttraumatic complications and adverse outcome.
Case presentation: We report the successful management of a 55-year old man who sustained a complete "bony disruption" of the thoracic cage secondary to an "all-terrain vehicle" roll-over accident. The injury pattern consisted of a bilateral "flail chest" with serial segmental rib fractures, bilateral hemo-pneumothoraces and pulmonary contusions, bilateral midshaft clavicle fractures, a displaced transverse sternum fracture with significant diastasis, and an unstable T9 hyperextension injury. After initial life-saving procedures, the chest wall injuries were sequentially stabilized by surgical fixation of bilateral clavicle fractures, locked plating of the displaced sternal fracture, and a two-level anterior spine fixation of the T9 hyperextension injury. The patient had an excellent radiological and physiological outcome at 6 months post injury.
Conclusion: Severe chest wall trauma with a complete "bony disruption" of the thoracic cage represents a rare, but detrimental injury pattern. Multidisciplinary management with a staged timing for addressing each of the critical injuries, represents the ideal approach for an excellent long-term outcome.

TI Enhancing hole mobility in III-V semiconductors
SO JOURNAL OF APPLIED PHYSICS
LA English
DT Article
ID QUANTUM-WELLS; CHANNEL; ENHANCEMENT; PARAMETERS; FETS
AB Transistors based on Ill-V semiconductor materials have been used for a variety of analog and high frequency applications driven by the high electron mobilities in materials. On the other hand, the hole mobility in materials has always lagged compared to group-IV semiconductors such as germanium. In this paper, we explore the use of strain and heterostructure design guided by bandstructure modeling to enhance the hole mobility in III-V materials. Parameters such as strain, valence band offset, effective masses, and splitting between the light and heavy hole bands that are important for optimizing hole transport are measured quantitatively using various experimental techniques. A peak Hall mobility for the holes of 960 cm(2)/Vs is demonstrated and the high hole mobility is maintained even at high sheet charge. (C) 2012 American Institute of Physics.

TI Prevalence and Factors Associated With Sleep Disturbances Among

AB Background. Sleep disturbances are reportedly common among persons infected with human immunodeficiency virus (HIV), but recent data, including comparisons with HIV-uninfected persons, are limited.
Methods. We performed a cross-sectional study among early-treated HIV-infected military beneficiaries (n = 193) to determine the prevalence and factors associated with insomnia (Pittsburgh Sleep Quality Index [PSQI]) and daytime sleepiness (Epworth Sleepiness Scale [ESS]). Data were compared with HIV-uninfected persons (n = 50) matched by age, sex, race or ethnicity, and military rank.
Results. Forty-six percent of HIV-infected persons had insomnia (PSQI >5), and 30% reported daytime drowsiness (ESS >= 10). The prevalence of insomnia and daytime sleepiness was not significantly higher compared with the HIV-uninfected group (38% [P = .30] and 20% [P = .18], respectively). In the multivariate model, factors associated with insomnia among HIV infected patients included depression (odds ratio [OR], 16.8; 95% confidence interval [CI], 2.0-142.1; P = .01), increased waist size (OR, 2.7; 95% CI, 1.4-5.1; P = .002), and fewer years of education (OR, 0.8; 95% CI, .7-.95; P = .006). Neurocognitive impairment (diagnosed in 19% of HIV-infected participants) was not associated with insomnia; however, HIV-infected persons with insomnia were 3.1-fold more likely to have a decline in activities of daily living than those without insomnia (23% vs 9%; P = .01). Only 18% of HIV-infected persons reported using a sleep medication at least weekly.
Conclusions. HIV-infected persons have a high prevalence of insomnia, but among an early-treated cohort this rate was not significantly higher compared with HIV-uninfected persons. Factors associated with insomnia among HIV-infected patients include depression and increased waist size. Prompt diagnosis and treatment of sleep disturbances are advocated and may improve quality of life.

AB This study examines the contribution of ocean dynamics to sea surface temperature (SST) biases in the eastern Pacific cold tongue region in fifteen coupled general circulation models (CGCMs) participating in the Intergovernmental Panel on Climate Change (IPCC) Fourth Assessment Report (AR4). Twenty years (1980-1999) of the twentieth-century (20C3m) climate simulations from each model are analyzed. An excessive and narrow SST cold tongue that extends too far west into the western Pacific in comparison to observations is a common bias in CGCMs. This feature is found in CGCMs analyzed here and in many previous studies. The heat budget analysis indicates that errors in both net surface heat flux and total upper ocean heat advection significantly contribute to the excessive cold tongue in the equatorial Pacific. The stronger heat advection in the models is caused by overly strong horizontal heat advection associated with too strong zonal currents, and overly strong vertical heat advection due to excessive upwelling and the vertical gradient of temperature. The Bjerknes feedback in the coupled models is shown to be weaker than in observations, which may be related to the insufficient response of surface zonal winds to SST in the models and an erroneous subsurface temperature structure. A hypothesis that describes how the cold tongue bias is possibly developed in the CGCMs is provided based on the results of our analysis.

PERSPECTIVE
AB STAR's measurements of directed flow (v(1)) around midrapidity for pi(+/-), K-+/-, K-S(0), p, and (p) over bar in Au + Au collisions at root s(NN) = 200 GeV are presented. A negative v(1) (y) slope is observed for most of produced particles (pi(+/-), K-+/-, K-S(0), p, and (p) over bar). In 5%-30% central collisions, a sizable difference is present between the v(1)(y) slope of protons and antiprotons, with the former being consistent with zero within errors. The v(1) excitation function is presented. Comparisons to model calculations (RQMD, UrQMD, AMPT, QGSM with parton recombination, and a hydrodynamics model with a tilted source) are made. For those models which have calculations of v(1) for both pions and protons, none of them can describe v(1()y) forpions and protons simultaneously. The hydrodynamics model with a tilted source as currently implemented cannot explain the centrality dependence of the difference between the v(1)(y) slopes of protons and antiprotons.

AB BACKGROUND: The authors conducted exploratory phase 1-2 clinical trials vaccinating breast cancer patients with E75, a human leukocyte antigen (HLA) A2/A3restricted HER-2/neu (HER2) peptide, and granulocyte-macrophage colony-stimulating factor. The vaccine is given as adjuvant therapy to prevent disease recurrence. They previously reported that the vaccine is safe and effective in stimulating expansion of E75-specific cytotoxic T cells. Here, they report 24-month landmark analyses of disease-free survival (DFS). METHODS: These dose escalation/schedule optimization trials enrolled lymph node-positive and high-risk lymph node-negative patients with HER2 (immunohistochemistry [IHC] 1-3+) expressing tumors. HLA-A2/A3+ patients were vaccinated; others were followed prospectively as controls for recurrence. DFS was analyzed by Kaplan-Meier curves; groups were compared using log-rank tests. RESULTS: Of 195 enrolled patients, 182 were evaluable: 106 (58.2%) in the vaccinated group and 76 (41.8%) in the control group. The 24-month landmark analysis DFS was 94.3% in the vaccinated group and 86.8% in the control group (P = .08). Importantly, because of trial design, 65% of patients received a lower than optimal vaccine dose. In subset analyses, patients who benefited most from vaccination (vaccinated group vs control group) had lymph node-positive (DFS, 90.2% vs 79.1%; P = .13), HER2 IHC 1+-2+ (DFS, 94.0% vs 79.4%; P = .04), or grade 1 or 2 (DFS, 98.4% vs 86.0%; P = .01) tumors and were optimally dosed (DFS, 97.3% vs 86.8%; P = .08). A booster program has been initiated; no patients receiving booster inoculations have recurred. CONCLUSIONS: The E75 vaccine has clinical efficacy that is more prominent in certain patients. A phase 3 trial enrolling lymph node-positive patients with HER2 low-expressing tumors is warranted. Cancer 2011. (c) 2011 American Cancer Society.

AB Olivine-type LiFePO4 is widely considered as a candidate for Li-ion battery electrodes, yet its applicability in the pristine state is limited due to poor ionic and electronic conduction. Doping can be employed to enhance the material's electrical conductivity. However, this should be understood as incorporating electrically active impurities to manipulate the concentration of native point defects such as lithium vacancies and small hole polarons which are responsible for ionic and electronic conduction, respectively, and not as generating band-like carriers. Possible effects of monovalent (Na, K, Cu, and Ag), divalent (Mg and Zn), trivalent (Al), tetravalent (Zr, C, and Si), and pentavalent (V and Nb) impurities on the ionic and electronic conductivities of LiFePO4 are analyzed based on results from first-principles density-functional theory calculations. We identify impurities that are effective (or ineffective) at enhancing the concentration of lithium vacancies or small hole polarons. Based on our studies, we discuss specific strategies for enhancing the electrical conductivity in LiFePO4 and provide suggestions for further experimental studies. Published by Elsevier B.V.

AB We present a two laser, multimode optoelectronic oscillator (OEO) for detecting unknown low-power RF signals. By switching between one or two lasers, the OEO cavity will become sensitive to an interleaved set of frequencies. The system has an input sensitivity of -78.4 dBm, which is only 14.2 dB higher than the thermal limit for a 140-MHz bandwidth. In addition, mode spacing has been increased to 100 MHz, a 20 times increase from previous demonstrations.

TI Ultra-low resistance ohmic contacts in graphene field effect transistors
SO APPLIED PHYSICS LETTERS

DT Article
ID DEVICE
AB We report on an experimental demonstration of graphene-metal ohmic contacts with contact resistance below 100 Omega mu m. These have been fabricated on graphene wafers, both with and without hydrogen intercalation, and measured using the transmission line method. Specific contact resistivities of 3 x 10(-7) to 1.2 x 10(-8) Omega cm(2) have been obtained. The ultra-low contact resistance yielded short-channel (source-drain distance of 0.45 mu m) HfO2/graphene field effect transistors (FETs) with a low on-resistance (R-on) of 550 Omega mu m and a high current density of 1.7 A/mm at a source-drain voltage of 1V. These values represent state-of-the-art (SOA) performance in graphene-metal contacts and graphene FETs. This ohmic contact resistance is comparable to that of SOA high-speed III-V high electron mobility transistors. (C) 2012 American Institute of Physics. [http://dx.doi.org/10.1063/1.4719579]

AB Deep levels in Se- and Pb-doped bulk TlBr detectors were characterized with photo-induced conductivity transient spectroscopy (PICTS) and cathodoluminescence (CL). Se-doped TlBr revealed two traps with energies of 0.35 and 0.45 eV in PICTS spectra. The Pb-doped material revealed three levels with energies of 0.11, 0.45, and 0.75 eV. CL measurements in both materials correlate with optical transitions involving some of the identified levels. The ambipolar carrier lifetimes of Se-doped and Pb-doped TlBr were measured with microwave reflectivity transients and found to be significantly lower than the lifetime of undoped TlBr.

ID RESONANCE FORCE MICROSCOPY; SPECTRAL DIFFUSION
AB We study magnetic fluctuations in a system of interacting spins on a lattice at high temperatures and in the presence of a spatially varying magnetic field. Starting from a microscopic Hamiltonian we derive effective equations of motion for the spins and solve these equations self-consistently. We find that the spin fluctuations can be described by an effective diffusion equation with a diffusion coefficient which strongly depends on the ratio of the magnetic field gradient to the strength of spin-spin interactions. We also extend our studies to account for external noise and find that the relaxation times and the diffusion coefficient are mutually dependent.

AB The Hyperspectral Imager for the Coastal Ocean (HICO) presently onboard the International Space Station (ISS) is an imaging spectrometer designed for remote sensing of coastal waters. The instrument is not equipped with any onboard spectral and radiometric calibration devices. Here we describe vicarious calibration techniques that have been used in converting the HICO raw digital numbers to calibrated radiances. The spectral calibration is based on matching atmospheric water vapor and oxygen absorption bands and extraterrestrial solar lines. The radiometric calibration is based on comparisons between HICO and the EOS/MODIS data measured over homogeneous desert areas and on spectral reflectance properties of coral reefs and water clouds. Improvements to the present vicarious calibration techniques are possible as we gain more in-depth understanding of the HICO laboratory calibration data and the ISS HICO data in the future.

AB Powerful, long-pulse lasers have a variety of applications. In many applications, optical elements are employed to direct, focus, or collimate the beam. Typically the optic is suspended in a gaseous environment (e.g., air) and can cool by convection. The variation of the optic temperature with time is obtained by combining the effects of laser heating, thermal conduction, and convective loss. Characteristics of the solutions in terms of the properties of the optic material, laser beam parameters, and the environment are discussed and compared with measurements at the Naval Research Laboratory, employing kW-class, 1 mu m wavelength, continuous wave lasers and optical elements made of fused silica or BK7 glass. The calculated results are in good agreement with the measurements, given the approximations in the analysis and the expected variation in the absorption coefficients of the glasses used in the experiments.

TI Optical turbulence on underwater image degradation in natural
environments
SO APPLIED OPTICS
LA English
DT Article
ID POLARIZATION; RESTORATION; VISIBILITY; ATMOSPHERE
AB It is a well-known fact that the major degradation source on electro-optical imaging underwater is from scattering by particles of various origins and sizes. Recent research indicates that, under certain conditions, the apparent degradation could also be caused by the variations of index of refraction associated with temperature and salinity microstructures in the ocean and lakes. The combined impact has been modeled previously through the simple underwater imaging model. The current study presents the first attempts in quantifying the level of image degradation due to optical turbulence in natural waters in terms of modulation transfer functions using measured turbulence dissipation rates. Image data collected from natural environments during the Skaneateles Optical Turbulence Exercise are presented. Accurate assessments of the turbulence conditions are critical to the model validation and were measured by two instruments to ensure consistency and accuracy. Optical properties of the water column in the field were also measured in coordination with temperature, conductivity, and depth. The results show that optical turbulence degrades the image quality as predicted and on a level comparable to that caused by the particle scattering just above the thermocline. Other contributing elements involving model closure, including temporal and spatial measurement scale differences among sensors and mitigation efforts, are discussed.

SO PHYSICAL REVIEW LETTERS
LA English
DT Article
ID REFRACTION; RADIATION; INDEX
AB Contrary to conventional wisdom that light bends away from the normal when it passes from high to low refractive index media, here we demonstrate an exotic phenomenon that the direction of electromagnetic power can bend toward the normal when light is incident from an arbitrary high refractive index medium (or air) to a epsilon-near-zero (ENZ) metamaterial. Moreover, the direction of the transmission is close to the normal for all angles of incidence. This anti-Snell's law refraction results from the interplay between ENZ and material loss. The loss can increase the transmission at the air-ENZ interface and collimate the beam inside the ENZ medium. Furthermore, in an ideal loss configuration, the propagation loss in anisotropic ENZ materials can approach zero when the material loss goes to infinity.

AB The 2001 April 15 event was one of the largest of the last solar cycle. A former study established that this event was associated with a coronal mass ejection (CME) observed both at white light and radio frequencies. This radio CME is illuminated by synchrotron emission from relativistic electrons. In this paper, we investigate the relation of the radio CME to its extreme-ultraviolet (EUV) and white-light counterpart and reach four main conclusions. (1) The radio CME corresponds to the white-light flux rope cavity. (2) The presence of a reconnecting current sheet behind the erupting flux rope is framed, both from below and above, by bursty radio sources. This reconnection is the source of relativistic radiating electrons which are injected down along the reconnected coronal arches and up along the flux rope border forming the radio CME. (3) Radio imaging reveals an important lateral overexpansion in the low corona; this overexpansion is at the origin of compression regions where type II and III bursts are imaged. (4) Already in the initiation phase, radio images reveal large-scale interactions of the source active region (AR) with its surroundings, including another AR and open magnetic fields. Thus, these complementary radio, EUV, and white-light data validate the flux rope eruption model of CMEs.

ID SCHOTTKY BARRIERS; SILICON; GROWTH; FILMS
AB Vertical diodes of epitaxial graphene on n(-) 4H-SiC were investigated. The graphene Raman spectra exhibited a higher intensity in the G-line than the 2D-line, indicative of a few-layer graphene film. Rectifying properties improved at low temperatures as the reverse leakage decreased over six orders of magnitude without freeze-out in either material. Carrier concentration of similar to 10(16) cm(-3) in the SiC remained stable down to 15 K, while accumulation charge decreased and depletion width increased in forward bias. The low barrier height of 0.08 eV and absence of recombination-induced emission indicated majority carrier field emission as the dominant conduction mechanism. (C) 2012 American Institute of Physics.

AB Nitrogen-rich 5-(1-methylhydrazinyl)tetrazole (1, MHT) was synthesized by using a straightforward method. White plate crystals of 1 were isolated in acetonitrile and crystallized in the monoclinic system P2(1)/c (# 14) (a = 3.8713(18) angstrom, b = 12.770(6) angstrom, c = 9.974(5) angstrom, alpha = 90 degrees, beta = 93.397(6)degrees, gamma = 90 degrees, V = 492.3(4) angstrom(3), Z = 4). The reactions of Cu(II) and Ag(I) ions in aqueous solution with 1 were investigated and found to form two complexes under mild conditions. The crystal structures of 2 and 3 are discussed with respect to the coordination mode of the MHT anion. Thermal stabilities were determined from differential scanning calorimetry (DSC) combined with thermogravimetric analysis (TGA) tests. Impact sensitivity was determined by BAM standards showing that these MHT salts are insensitive to impact (>40 J) confirmed by UN standards. The energies of combustion of 1-3 were determined using oxygen bomb calorimetry values and were used to obtain the corresponding enthalpies of formation. Combined with these data above, the neutral MHT is an attractive nitrogen-rich ligand for metallic energetic materials. Its copper and silver coordinated complexes are of interest as potential "green" metal energetic materials with high thermal stability as well as low sensitivity to impact and a high molar enthalpy of formation.

TI Temperature versus salinity gradients below the ocean mixed layer
SO JOURNAL OF GEOPHYSICAL RESEARCH-OCEANS

DT Article
ID WESTERN EQUATORIAL PACIFIC; SURFACE-LAYER; BARRIER LAYER; VARIABILITY;
DEPTHS; HEAT; SEA; STRATUS; BURSTS
AB We characterize the global ocean seasonal variability of the temperature versus salinity gradients in the transition layer just below the mixed layer using observations of conductivity temperature and depth and profiling float data from the National Ocean Data Center's World Ocean Data set. The balance of these gradients determines the temperature versus salinity control at the mixed layer depth (MLD). We define the MLD as the shallowest of the isothermal, isohaline, and isopycnal layer depths (ITLD, IHLD, and IPLD), each with a shared dependence on a 0.2 degrees C temperature offset. Data are gridded monthly using a variational technique that minimizes the squared analysis slope and data misfit. Surface layers of vertically uniform temperature, salinity, and density have substantially different characteristics. By examining differences between IPLD, ITLD, and IHLD, we determine the annual evolution of temperature or salinity or both temperature and salinity vertical gradients responsible for the observed MLD. We find ITLD determines MLD for 63% and IHLD for 14% of the global ocean. The remaining 23% of the ocean has both ITLD and IHLD nearly identical. It is found that temperature tends to control MLD where surface heat fluxes are large and precipitation is small. Conversely, salinity controls MLD where precipitation is large and surface heat fluxes are small. In the tropical ocean, salinity controls MLD where surface heat fluxes can be moderate but precipitation is very large and dominant.

TI Extending electro-optic detection to ultrashort electron beams
SO PHYSICAL REVIEW SPECIAL TOPICS-ACCELERATORS AND BEAMS
LA English
DT Article
ID RADIATION; ACCELERATOR; BUNCHES
AB We propose a technique to extend noninvasive electro-optic detection of relativistic electron beams to bunch lengths of similar or equal to 10 fs. This is made possible by detecting the frequency mixing that occurs between the optical probe and the space charge fields of the beam, while simultaneously time resolving the resulting mixed frequency signal. The necessary formalism to describe this technique is developed and numerical solutions for various possible experimental conditions are made. These solutions are then compared to simulation results for consistency. Finally, the method to reconstruct the original bunch profile from the proposed diagnostic is discussed and an example showing a 15 fs test beam reconstructed to within an accuracy of 15% is given.

AB A comparative cost/benefit and energy balance analysis addresses the critical scientific and technical challenges that impact the economic feasibility of synthesizing up to 100 000 gal per day of jet fuel at sea using carbon dioxide (CO2) and hydrogen (H-2) from the sea. Included in this analysis are the capital cost, operation and maintenance, and electrical generation cost for synthesizing jet fuel at sea using either ocean thermal energy conversion or nuclear power processes as the energy source. The results suggest that jet fuel could be produced at sea for $3 to $6/gal. Comparing these costs with current and historical prices of fuel purchased by the Department of Defense provides insight into the economic and operational benefits of a sea-based fuel synthesis process for the Navy.

AB A 20-year-old male presented with symptoms of meningococcal sepsis and died despite appropriate medical interventions. Blood cultures grew N. meningitidis serogroup Y. The patient had received the meningococcal quadrivalent (A,C,W-135,Y) polysaccharide vaccine 15 months previously. Because the patient had a history of meningococcal meningitis at age 10, archived serum was obtained for further analysis. Complement component C7 was found to be deficient and antibody levels to meningococcal polysaccharides were undetectable for two serogroups and low for the infecting serogroup 10 months post-vaccination. This case highlights the fact that some individuals with terminal complement component deficiencies mount an impaired or short-lived response to vaccination with meningococcal capsular polysaccharides and underscores the appropriateness of a more aggressive vaccination strategy in this patient population.

SO JOURNAL OF REFRACTIVE SURGERY

ID PHAKIC INTRAOCULAR-LENS
AB PURPOSE: To report traumatic dislocation of a Visian Implantable Collamer Lens (ICL, STAAR Surgical Co) discovered on routine examination.
METHODS: A 26-year-old man was found to have ICL subluxation into the anterior chamber with pupillary capture on routine screening examination. The patient reported being punched near the left eye 2 weeks earlier. He noted mild blurry vision, no pain, and uncorrected distance visual acuity (UDVA) was 20/30, which was decreased from his baseline of 20/20 in the affected eye.
RESULTS: Surgical repositioning was performed under pupillary dilation without complication. Postoperatively, UDVA was 20/20(-2). Persistent pigment on the ICL, slight pupillary margin peaking, and anterior chamber inflammation were noted.
CONCLUSIONS: Traumatic ICL dislocation may occur with minimal signs and symptoms. Education of patients about the necessity for examination after ocular trauma and need to wear eye protection during activities at high risk of ocular trauma are important.

AB Foam fraction can be retrieved from space-based microwave radiometric data at frequencies from 1 to 37 GHz. The retrievals require modeling of ocean surface emissivity fully covered with sea foam. To model foam emissivity well, knowledge of foam properties, both mechanical and dielectric, is necessary because these control the radiative processes in foam. We present a physical description of foam dielectric properties obtained from the foam dielectric constant including foam skin depth; foam impedance; wavelength variations in foam thickness, roughness of foam layer interfaces with air and seawater; and foam scattering parameters such as size parameter, and refraction index. Using these, we analyze the scattering, absorption, reflection and transmission in foam and gain insights into why volume scattering in foam is weak; why the main absorption losses are confined to the wet portion of the foam; how the foam impedance matching provides the transmission of electromagnetic radiation in foam and maximizes the absorption; and what is the potential for surface scattering at the foam layers boundaries. We put all these elements together and offer a conceptual understanding for the high, black-body-like emissivity of foam floating on the sea surface. We also consider possible scattering regimes in foam.

AB Background: In the past decade spherical and rod-like viruses have been used for the design and synthesis of new kind of nanomaterials with unique chemical positioning, shape, and dimensions in the nanosize regime. Wild type and genetic engineered viruses have served as excellent templates and scaffolds for the synthesis of hybrid materials with unique properties imparted by the incorporation of biological and organic moieties and inorganic nanoparticles. Although great advances have been accomplished, still there is a broad interest in developing reaction conditions suitable for biological templates while not limiting the material property of the product.
Results: We demonstrate the controlled synthesis of copper nanorods and nanowires by electroless deposition of Cu on three types of Pd-activated rod-like viruses. Our aqueous solution-based method is scalable and versatile for biotemplating, resulting in Cu-nanorods 24-46 nm in diameter as measured by transmission electron microscopy. Cu2+ was chemically reduced onto Pd activated tobacco mosaic virus, fd and M13 bacteriophages to produce a complete and uniform Cu coverage. The Cu coating was a combination of Cu-0 and Cu2O as determined by X-ray photoelectron spectroscopy analysis. A capping agent, synthesized in house, was used to disperse Cu-nanorods in aqueous and organic solvents. Likewise, reactions were developed to produce Cu-nanowires by metallization of polyaniline-coated tobacco mosaic virus.
Conclusions: Synthesis conditions described in the current work are scalable and amenable for biological templates. The synthesized structures preserve the dimensions and shape of the rod-like viruses utilized during the study. The current work opens the possibility of generating a variety of nanorods and nanowires of different lengths ranging from 300 nm to micron sizes. Such biological-based materials may find ample use in nanoelectronics, sensing, and cancer therapy.

AB The Marine Resiliency Study (MRS) is a prospective study of factors predictive of posttraumatic stress disorder (PTSD) among approximately 2,600 Marines in 4 battalions deployed to Iraq or Afghanistan. We describe the MRS design and predeployment participant characteristics. Starting in 2008, our research team conducted structured clinical interviews on Marine bases and collected data 4 times: at predeployment and at 1 week, 3 months, and 6 months postdeployment. Integrated with these data are medical and career histories from the Career History Archival Medical and Personnel System (CHAMPS) database. The CHAMPS database showed that 7.4% of the Marines enrolled in MRS had at least 1 mental health diagnosis. Of enrolled Marines, approximately half (51.3%) had prior deployments. We found a moderate positive relationship between deployment history and PTSD prevalence in these baseline data.

ID CONDUCTION
AB This paper extends the velocity dependent Krook (VDK) model, developed at NRL over the last 4 years, to two dimensions and presents a variety of calculations. One dimensional spherical calculations presented here investigate shock ignition. Comparing VDK calculations to a flux limit calculation shows that the laser profile has to be retuned and some gain is sacrificed due to preheat of the fuel. However, preheat is by no means a show stopper for laser fusion. The recent foil acceleration experiments at the University of Rochester Laboratory for Laser Energetics are modeled with two-dimensional simulations. The radial loss is very important to consider in modeling the foil acceleration. Once this is done, the VDK model gives the best agreement with the experiment. (C) 2012 American Institute of Physics.

AB A 52-year-old man with well-controlled HIV infection taking ritonavir and increasing doses of inhaled fluticasone for chronic bronchitis developed thrush. Within days of discontinuing fluticasone and initiating fluconazole, he presented with fatigue, malaise, lower-extremity oedema and orthostasis. Testing confirmed exogenous Cushing's syndrome and secondary adrenal insufficiency. Although ritonavir-fluticasone interactions have been previously reported as a cause for adrenal insufficiency, we propose that fluconazole increased the rapidity of onset and severity of symptoms through synergistic inhibition of the adrenal axis.

AB We have generated slim edges on manufactured silicon strip detectors by cleaving the non-active edge material and passivating the very smooth edge with a thin coat of silicon oxide. We report a comparison of I-V measurements and charge collection and noise measurements on two identical sensors, one with and one without slim edge treatment. The current voltage measurements of the entire sensor and individual strips indicate that the large current increase due to the treatment is confined to the guard ring, while the strips show essentially no increase in leakage currents. The noise on all strips, including the one adjacent to the slim edge, is not changed by the cut. The signal from a beta source before and after cutting is the same within 4%.

AB Although the assertion of a link between vaccines and autism has been scientifically rejected, the theory continues to be popular and may influence the attitudes of parents of children with autism spectrum disorders. The authors sought to assess how often parents change or discontinue their child's vaccine schedule after autism spectrum disorder diagnosis and whether beliefs about the etiology of autism affect their decision to do so. The authors surveyed 197 (43%) of 460 eligible parents of children under 18 years of age with autism spectrum disorders who were enrolled in a state-funded agency that provides services to those with developmental disabilities in western Los Angeles County. Half of the parents discontinued or changed vaccination practices, and this was associated with a belief that vaccines contributed to autism spectrum disorders, indicating a potential subset of undervaccinated children. Educational tools should be designed to assist physicians when talking to parents of children with autism spectrum disorders about vaccination.

The adaptation of microarray-based resequencing technology for microbial detection and characterization resulted in the development of a number assays that have unique advantages over other existing technologies. This technological platform seems to be especially useful for sensitive and high-resolution multiplexed diagnostics for clinical syndromes with similar symptoms, screening environmental samples for biothreat agents, as well as genotyping and whole-genome analysis of single pathogens.

AB A new method is presented for computation of optimal control for linear systems using Haar wavelets. The method is based on a novel operational matrix derived from integration of Haar wavelets. The optimal control problem, is converted to a two-point-boundary-value problem, which is then solved using the Haar wavelet transformation. The proposed method is then extended to the numerical solution for optimization of singular systems. Accuracy of the solution can be improved by increasing the resolution of wavelet expansion, i.e., by increasing the order of transformation. Compared with known methods in the literature, the proposed method does not require explicit computation of wavelet coefficients, which makes it computationally more efficient and requires less computer memory. Simulation results are presented to illustrate the method.

AB Graphene has recently attracted wide-spread attention because of its unique transport and physical properties that are appealing for a wide range of electronic applications. Integration with scalable high-kappa dielectrics is important for the realization of graphene-based top-gated electronic devices, including next generation THz applications. Atomic layer deposition (ALD), a low temperature deposition method based on two separate self-limiting surface reactions, is a preferred technique to achieve high-quality, conformal, ultrathin dielectric films with precise control of thickness and chemical composition at the atomic scale. Unfortunately, ALD of oxides on graphene is hindered by the inertness of the graphene surface. To alleviate this graphene-oxide incompatibility, several different functionalization and seeding methods have recently been developed to render the graphene more susceptible to the ALD process of high-kappa dielectrics including: ozone, wet chemical and fluorine pretreatments, low-k polymer seed, e-beam metal, and oxide seed layers. The ability of each approach to enable conformal, uniform high-kappa dielectrics on graphene while maintaining its inherent transport properties for low power, high-frequency device applications is discussed.

DT Article
ID ELECTRONIC TRANSPORT; EDGE
AB Quantum transport calculations describing electron scattering off an extended line defect in graphene are presented. The calculations include potentials from local magnetic moments recently predicted to exist on sites adjacent to the line defect. The transmission probability is derived and expressed as a function of valley, spin, and angle of incidence of an electron at the Fermi level being scattered. It is shown that the previously predicted valley polarization in a beam of transmitted electrons is not significantly influenced by the presence of the magnetic moments. These moments, however, do introduce some spin polarization, in addition to the valley polarization, albeit no more than about 20%. [http://dx.doi.org/10.1116/1.4706892]

AB Top-gated epitaxial graphene nanoribbon (EGNR) field effect transistors (FETs) were fabricated on epitaxial graphene substrates which demonstrated the opening of a substantial bandgap. Hydrogen silsesquioxane (HSQ) was used for the patterning of 10 nm size linewidth as well as a seed layer for atomic layer deposition (ALD) of a high-k dielectric aluminum oxide (Al2O3). It is found that the resolution of the patterning is affected by the development temperature, electron beam dose, and substrate materials.

Raman microscopy and x ray photoelectron spectroscopy demonstrate the uniqueness of this bilayer, as compared to a naturally formed bilayer, in that a Bernal stack is not formed with each layer being strained differently yet being closely coupled.

TI An Inflow Method for Axisymmetric Turbulent Boundary Layers Along Very
Long Slender Cylinders
SO JOURNAL OF FLUIDS ENGINEERING-TRANSACTIONS OF THE ASME
LA English
DT Article
ID LARGE-EDDY SIMULATION; A-PRIORI; FLOW
AB Generating acceptable inflow conditions for the turbulent boundary layer (TBL) growth along long thin cylinders is a challenging task. Previous production methods such as rescale/recycling, artificial turbulence, and antecedent databases are difficult to implement because the downstream physics do not conform to consistent scaling laws. An alternate inflow approach that involves only recycling the fluctuating elements coupled with a dynamic form of Spalding's relationship for assigning the mean quantities shows promise for spatially resolving the axisymmetric turbulence along the thin cylinder. Applying this inflow technique for resolving the turbulent scales along a flat plate at a tested momentum-based Reynolds number of Re-theta = 670 showed excellent agreement with the experimental data as well as the analytical results from the momentum-integral method. A minor adjustment length of approximately two inflow TBL thicknesses was necessary to attain consistent streamwise growth of the boundary layer as well as a simultaneous reduction of the skin friction. Unlike the flat plate, implementing the inflow technique for the thin cylinder required a feedback mechanism during the early transition phase to capture the downstream realistic turbulence. This initial process invoked downstream evaluation of the three parameters that comprise Spalding's relationship that were periodically fed upstream to the inflow boundary. The validation test case (Re-theta = 620) showed excellent agreement with the experimental measurements in terms of the radial profiles (in cylinder wall units) of the streamwise mean and the normal Reynolds stress. Both the adjustment and turbulence decorrelation axial lengths were under two boundary layer thicknesses from the inlet boundary. Given a useful inflow technique for the thin cylinder permits much needed numerical investigations to complement the present scarcity in the experimental evidence and address numerous unknown characteristics of the TBL spatial growth.

AB As part of NASA's mission to explore habitable planets orbiting nearby stars, this article explores the detection and characterization capabilities of a 4 m space telescope plus 50 m starshade located at the Earth-Sun L2 point, known as the New Worlds Observer (NWO). Our calculations include the true spectral types and distribution of stars on the sky, an iterative target selection protocol designed to maximize efficiency based on prior detections, and realistic mission constraints. We conduct simulated observing runs for a wide range in exozodiacal background levels (epsilon = 1-100 times the local zodi brightness) and overall prevalence of Earth-like terrestrial planets (eta(circle plus) = 0.1-1). We find that even without any return visits, the NWO baseline architecture (IWA = 65 mas, limiting FPB = 4 x 10(-11)) can achieve a 95% probability of detecting and spectrally characterizing at least one habitable Earth-like planet and an expectation value of similar to 3 planets found, within the mission lifetime and Delta V budgets, even in the worst-case scenario (eta(circle plus) = 0.1 and epsilon = 100 zodis for every target). This achievement requires about 1 yr of integration time spread over the 5 yr mission, leaving the remainder of the telescope time for UV-NIR general astrophysics. Cost and technical feasibility considerations point to a "sweet spot" in starshade design near a 50 m starshade effective diameter, with 12 or 16 petals, at a distance of 70,000-100,000 km from the telescope.

AB Full range Herschel/PACS spectroscopy of the (ultra) luminous infrared galaxies NGC 4418 and Arp 220, observed as part of the SHINING key programme, reveals high excitation in H2O, OH, HCN, and NH3. In NGC 4418, absorption lines were detected with E-lower > 800 K (H2O), 600 K (OH), 1075 K (HCN), and 600 K (NH3), while in Arp 220 the excitation is somewhat lower. While outflow signatures in moderate excitation lines are seen in Arp 220 as have been seen in previous studies, in NGC 4418 the lines tracing its outer regions are redshifted relative to the nucleus, suggesting an inflow with. (M) over dot less than or similar to 12 M-circle dot yr(-1). Both galaxies have compact and warm (T-dust greater than or similar to 100 K) nuclear continuum components, together with a more extended and colder component that is much more prominent and massive in Arp 220. A chemical dichotomy is found in both sources: on the one hand, the nuclear regions have high H2O abundances, similar to 10(-5), and high HCN/H2O and HCN/NH3 column density ratios of 0.1-0.4 and 2-5, respectively, indicating a chemistry typical of evolved hot cores where grain mantle evaporation has occurred. On the other hand, the high OH abundance, with OH/H2O ratios of similar to 0.5, indicates the effects of X-rays and/or cosmic rays. The nuclear media have high surface brightnesses (greater than or similar to 10(13) L-circle dot/kpc(2)) and are estimated to be very thick (N-H greater than or similar to 10(25) cm(-2)). While NGC 4418 shows weak absorption in (H2O)-O-18 and (OH)-O-18, with a O-16-to-O-18 ratio of greater than or similar to 250-500, the relatively strong absorption of the rare isotopologues in Arp 220 indicates O-18 enhancement, with O-16-to-O-18 of 70-130. Further away from the nuclear regions, the H2O abundance decreases to less than or similar to 10(-7) and the OH/H2O ratio is reversed relative to the nuclear region to 2.5-10. Despite the different scales and morphologies of NGC 4418, Arp 220, and Mrk 231, preliminary evidence is found for an evolutionary sequence from infall, hot-core like chemistry, and solar oxygen isotope ratio to high velocity outflow, disruption of the hot core chemistry and cumulative high mass stellar processing of O-18.

TI High spatial resolution VAULT H-Ly alpha observations and
multiwavelength analysis of an active region filament

AB Context. The search for the fine structure of prominences has received considerable new attention thanks to the Swedish Solar Telescope (SST) H alpha pictures that provide an unsurpassed spatial resolution. Recently, it has been shown that the filaments' coronal environment, at least for quiescent filaments, is perturbed by either cool absorbing material (in the EUV) or an "emissivity blocking" (actually a lack of transition region and coronal material).
Aims. The aim is to assess the fine structure in an active region filament and to determine the nature of the EUV absorption or lack of emission phenomena, using the very optically thick line H-Ly alpha, formed at a temperature higher than H alpha.
Methods. We performed a multiwavelength study where high-resolution imaging in the H-Ly alpha line (VAULT) was analysed and compared with observations of an active region filament in H alpha (BBSO) and EUV lines (EIT and TRACE).
Results. As for the SST data, small-scale structures were detected at a typical scale of about one to two arcseconds with, for some cuts, an indication of fine scales down to 0.4 arcsec in the optically thick H-Ly alpha line. The filament intensity relative to the intensity of the (active) region it is embedded in is about 0.2 in H-Ly alpha. This ratio (Lymana ratio intensity or "LRI") is the lowest value compared to other lines, e. g. H alpha. The filament environment was also investigated and evidence of an UV extension was found. The comparison of spatial cuts in different lines across the filament shows evidence of strong absorption, and consequently of cool plasma on one side of the filament, but not on the other (that side is obscured by the filament itself).
Conclusions. The absence of very fine structure in H-Ly alpha compared to H alpha is explained by the formation temperature of the H-Ly alpha line (similar to 20 000 K), where the transition regions of the thin threads begin to merge. From the detection of H-Ly alpha absorption on the observable side of the filament side, we derive the presence of absorbing (cool) material and possibly also of emissivity blocking (or coronal void). This poses the question whether these absorption effects are typical of active region filaments.

AB The ferroelectrically active acoustic wave equation including electrostriction effects is derived from nonlinear constitutive equations of stress and electric displacement for ferroelectric materials exhibiting significant electrostrictive strain. Electrically controllable acoustic wave propagation is predicted by solving the equation as a function of various acoustic variables, e. g., wave excitation, polarization, dc bias, etc. As examples, the elastic, piezoelectric, and ferroelectric acoustic waves and the electromechanical coupling factors are computed as a function of wave propagation in the [100]-[010] plane of BaTiO3 under thickness excitation mode.

DE underwater imaging; multiframe restoration; imaging through turbulence
AB The ability to image underwater is highly desired for scientific and military applications, including optical communications, submarine awareness, diver visibility, and mine detection. Underwater imaging is severely impaired by scattering and optical turbulence associated with refractive index fluctuations. This work introduces a novel approach to restoration of degraded underwater imagery based on a multi-frame correction technique developed for atmospheric distortions. The method represents synthesis of "lucky-region" fusion with nonlinear gain and optical flow-based image warping. The developed multiframe image restoration algorithm is tested on underwater imagery collected in a laboratory tank and in a field exercise. Reliance of image restoration on accuracy of the optical flow algorithm is revealed. The developed algorithm demonstrates significant resolution improvement of the restored image in comparison to any single frame or the mean of the underwater image sequence.

AB We describe a process for selective metallization of paper substrates bearing inkjet printed patterns of a commercial Pd/Sn colloidal catalyst ink plated using a commercial electroless Cu bath. The electrical conductivity of the Cu films is analyzed as a function of feature geometry (line dimensions (L) and spacing (S)), type of paper (P), age of the Pd/Sn patterns (A), plating time (T), and plating temperature (H) using a two-level factorial design. Conductivity is influenced predominantly by the P, T, and H factors, with lesser contributions attributed to pair-wise interactions among several of the variables studied. Increases in T and/or H enhance conductivity of the Cu films, whereas increases in P, corresponding to the use of rougher, more porous, paper substrates, yield Cu films exhibiting decreased conductivity. Our analysis leads to a model that predicts Cu film conductivity well over the ranges of variables examined, provides guidelines for identification of optimum conditions for plating highly conductive Cu films, and identifies areas for further process improvement.

AB Bistable organic molecules were deposited on a weakly binding III-V semiconductor surface and then pinned Into place using individual native adatoms. These pinning atoms, positioned by atomically precise manipulation techniques in a cryogenic scanning tunneling microscope (STM) at 5 K, stabilize the pi-conjugated molecule against rotation excited by the tunneling electrons. The pinning allows triggering of the molecule's intrinsic switching mechanism (a hydrogen transfer reaction) by the STM tunnel current. Density-functional theory calculations reveal that the energetics of the switching process is virtually unaffected by both the surface and the pinning atoms. Hence, we have demonstrated that individual molecules with predictable, predefined functions can be stabilized and assembled on semiconductor templates.

AB We report temperature-dependent measurements of the terahertz (THz) vibrational spectrum of ammonium nitrate (AN) films and mixed potassium nitrate (KN)-ammonium nitrate films using waveguide THz time domain spectroscopy. The experiments were performed on polycrystalline films on the metal surface of a parallel plate waveguide. At cryogenic temperature and with frequency resolution as high as 7 GHz, our measurements produce a complex vibrational spectrum for AN, and show vibrational resonances not observed in previous far infrared and Raman measurements. We investigate potential interactions between AN and the metal surface by measuring THz spectra of films on aluminum, gold, and a gold surface coated with an organic self-assembled monolayer. Measurements are also performed on a deuterated AN film and indicate that the observed THz modes are due largely to the motion of the nitrate ions in the AN crystal. Finally, the effect of introducing small amounts of an impurity into the AN lattice is examined. We find that introduction of as little as 1%-2% by weight of potassium nitrate into the AN lattice causes line broadening of the THz modes, which is consistent with increased disorder introduced by the impurity.

ID RELAXATION; CD1-XMNXTE
AB We develop an approach for tuning the spin splitting and g-factor of a quantum dot by coupling it to semi-magnetic quantum dot and tuning the electric field. We show that spin splittings and g-factors of the states of a non-magnetic quantum dot coupled to semi-magnetic quantum dot can be enhanced orders of magnitude. Evaluations are made for coupled CdTe/CdMnTe quantum dots. These effects are caused by electric field control of repulsion of spin sublevels in the non-magnetic dot due to tunnel coupling of quantum dots. Electric field control of spin splittings in quantum dots is of potential interest in connection with spin qubit rotations for quantum computation. (C) 2012 American Institute of Physics.

AB We investigated the pattern and potential adaptive value of phenolic concentrations in galls induced by the aphid on leaves of . By the time that founding females began reproduction, galls had higher concentrations of condensed tannins and lower concentrations of hydrolyzable tannins than leaves. Galled and ungalled leaf laminas never differed significantly in any phenolic measure. Condensed tannin concentrations also were positively related to the number of offspring per gall when gall dry weight, another important correlate of fecundity, was accounted for. This could indicate the prior sink strength of the gall. Polyphenols may act as a repository for excess carbon drawn to the gall by increased sink strength, or be an indication of the fundatrix' ability to manipulate host physiology. This study is the first to demonstrate a tangible, quantitative association between phenolic accumulation in galls and gall-former reproductive performance, and illustrates that condensed tannins may play roles other than plant defense.

The effect of organic matter (OM) on the flocculation of colloidal montmorillonite was investigated through a complementary use of laboratory experiments and computational flocculation modeling. The model, based on Smoluchowski's coagulation model and population balance equation (PBE), was established with two key flocculation parameters: sticking efficiency and breakup parameter. The laboratory flocculation experiments tracked the temporal evolution of the mean floc sizes for aqueous systems with colloidal bare montmorillonite as well as those with montmorillonite and OM (humic acid, chitin, or xanthan gum). The key flocculation parameters were derived and calibrated through the interactive optimization of the model results by juxtaposing against the laboratory results.
The calibrated flocculation parameter values revealed that OM has a complex influence on the flocculation behavior of montmorillonite. They also showed that the effect of OM on flocculation depends on the types of OM. For example, xanthan gum does not significantly modify the flocculation behavior of montmorillonite that is primarily determined by the electrical double-layer repulsion (i.e., zeta-potential) and van der Waals attraction [i.e., Derjaguin and Laudau, Verwey and Overbeek (DLVO) interaction energies], whereas chitin modifies both the sticking efficiency and breakup parameter.
This study illustrates that there is no universally predictive correlation between DLVO energies or zeta-potential and flocculation parameters, as some OM has little effect on the DLVO interaction of montmorillonite colloids whereas other types of OM exert significant non-DLVO interactions such as repulsive hydration, steric repulsion, and polymer bridging. Further understanding of the physical-chemical properties of OM is needed in order to predict the flocculation behaviors of estuarine and coastal suspended colloids.

SO JOURNAL OF THE ACOUSTICAL SOCIETY OF AMERICA
LA English
DT Article
AB Transducers for acoustic beacons which can produce outgoing signals with wave fronts whose horizontal cross sections are circular or spiral are studied experimentally. A remote hydrophone is used to determine its aspect relative to the transducers by comparing the phase of the circular signal to the phase of the spiral signal. The transducers for a "physical-spiral" beacon are made by forming a strip of 1-3 piezocomposite transducer material around either a circular or spiral backing. A "phased-spiral" beacon is made from an array of transducer elements which can be driven either in phase or staggered out of phase so as to produce signals with either a circular or spiral wave front. Measurements are made to study outgoing signals and their usefulness in determining aspect angle. Vertical beam width is also examined and phase corrections applied when the hydrophone is out of the horizontal plane of the beacon. While numerical simulations indicate that the discontinuity in the physical-spiral beacon introduces errors into the measured phase, damping observed at the ends of the piezocomposite material is a more significant source of error. This damping is also reflected in laser Doppler vibrometer measurements of the transducer's surface velocity. [http://dx.doi.org/10.1121/1.3699170]

ID EQUATION
AB The paper considers receiving acoustic horns designed for particle velocity amplification and suitable for use in vector sensing applications. Unlike conventional horns, designed for acoustic pressure amplification, acoustic velocity horns (AVHs) deliver significant velocity amplification even when the overall size of the horn is much less than an acoustic wavelength. An AVH requires an open-ended configuration, as compared to pressure horns which are terminated at the throat. The appropriate formulation, based on Webster's one-dimensional horn equation, is derived and analyzed for single conical and exponential horns as well as for double-horn configurations. Predicted horn amplification factors (ratio of mouth-to-throat radii) were verified using numerical modeling. It is shown that three independent geometrical parameters principally control a horn's performance: length l, throat radius R-1, and flare rate. Below a predicted resonance region, velocity amplification is practically independent of frequency. Acoustic velocity horns are naturally directional, providing maximum velocity amplification along the boresight. (C) 2012 Acoustical Society of America. [http://dx.doi.org/10.1121/1.3702432]

AB Auditory evoked potential (AEP) data are commonly obtained in air while sea lions are under gas anesthesia; a procedure that precludes the measurement of underwater hearing sensitivity. This is a substantial limitation considering the importance of underwater hearing data in designing criteria aimed at mitigating the effects of anthropogenic noise exposure. To determine if some aspects of underwater hearing sensitivity can be predicted using rapid aerial AEP methods, this study measured underwater psychophysical thresholds for a young male California sea lion (Zalophus californianus) for which previously published aerial AEP thresholds exist. Underwater thresholds were measured in an aboveground pool at frequencies between 1 and 38 kHz. The underwater audiogram was very similar to those previously published for California sea lions, suggesting that the current and previously obtained psychophysical data are representative for this species. The psychophysical and previously measured AEP audiograms were most similar in terms of high-frequency hearing limit (HFHL), although the underwater HFHL was sharper and occurred at a higher frequency. Aerial AEP methods are useful for predicting reductions in the HFHL that are potentially independent of the testing medium, such as those due to age-related sensorineural hearing loss.

AB BACKGROUND: As a primary venue for presenting research results, abstracts selected for presentation at national meetings should be of the highest scientific merit and research quality. It is uncertain to what degree this is achieved as the methodological quality of abstracts submitted to national surgical meetings has not been previously described. The objective of this study was to evaluate abstracts presented at a leading trauma meeting for methodological quality.
METHODS: All abstracts accepted for the 2009 American Association for the Surgery of Trauma meeting were reviewed and scored for methodological quality based on 10 criteria (scores, 0-10; 10 being the highest). Criteria were based on nationally published methodology guidelines. Two independent reviewers who were blinded to institution, region, and author reviewed each abstract.
RESULTS: A total of 187 abstracts were accepted for presentation (67 oral and 120 posters). The most frequent clinical topics were shock/transfusion (23%), abdomen (12%), and nervous system (11%). Shock/transfusion abstracts were more common in the oral presentations (31% vs. 19%; p = 0.06). Abstracts from the northeast and south regions were the most common in both oral (26% and 29%) and posters (25% and 24%). Basic science accounted for 12% of accepted studies, while 51% were clinical and 28% were health services/outcomes. Only 8% of abstracts presented randomized data and only 11% reported null findings. Overall abstract scores ranged from 3 to 10 (median, 7; mean, 7.4). Abstracts selected for poster presentation had an overall higher score than those selected for oral presentation (7.4 +/- 1.7 vs. 6.8 +/- 1.7; p = 0.02).
CONCLUSION: Although oral presentations traditionally receive the most attention and interest, the methodological quality of abstracts accepted for poster presentation equals (and sometimes exceeds) that of oral abstracts. Attendees of these national meetings should reconsider their time spent in viewing and visiting these poster sessions as with the oral presentations. In light of our findings, we highly encourage that all members and guests attend the American Association for the Surgery of Trauma Poster Rounds at each year's scientific assembly.

AB The present paper gives a technical review of fracture toughness testing, evaluation and standardization for metallic materials in terms of the linear elastic fracture mechanics as well as the elastic-plastic fracture mechanics. This includes the early investigations and recent advances of fracture toughness test methods and practices developed by American Society for Testing and Materials (ASTM). The review describes the most important fracture mechanics parameters: the elastic energy release rate G, the stress intensity factor K, the J-integral, the crack-tip opening displacement (CTOD) and the crack-tip opening angle (CTOA) from the basic concept, definition, to experimental estimation, test methods and ASTM standardizing practices. Attention is paid to guidelines on how to choose an appropriate fracture parameter to characterize fracture toughness for the material of interest, and how to measure the fracture toughness value defined either at a critical point or in a resistance curve format using laboratory specimens. The relevant ASTM fracture toughness test standards considered in this paper are E399 for K-lc testing, E561 for K-R curve testing, E813 for J(lc) testing, E1152 for J-R curve testing, E1737 for J(lc) and J-R curve testing, E1290 for CTOD (delta) testing, a combined common test standard E1820 for measuring the three parameters of K, J and delta, E1921 for the transition reference temperature T-0 testing and the master curve of cleavage toughness K-Jc testing, and E2472 for CTOA testing. The effects of loading rate, temperature and crack-tip constraint on fracture toughness as well as fracture instability analysis are also reviewed. (C) 2012 Elsevier Ltd. All rights reserved.

AB In this work, the plasticity and ductile fracture behaviors of an aluminum alloy 5083-H116 are studied through a series of experiments and finite element analyses. A recently developed stress state dependent plasticity model, the I-1-J(2)-J(3) plasticity model, is implemented to describe the plastic response of this material. Furthermore, a ductile failure criterion based on a damage parameter defined in terms of the accumulative plastic strain as a function of the stress triaxiality and the Lode angle is established. The calibrated I-1-J(2)-J(3) plasticity model and ductile failure model are utilized to study the residual stress effect on ductile fracture resistance. A local out-of-plane compression approach is employed to generate residual stress fields in the compact tension specimens. Fracture tests of C(T) specimens having zero, positive and negative residual stresses are conducted. The numerical results, such as load-displacement curves and crack front profiles, are compared with experimental measurements and good agreements are observed. Both experimental and finite element results show significant effect of residual stress on ductile fracture resistance. (C) 2012 Elsevier Ltd. All rights reserved.

AB This paper addresses the challenge of using autonomous soaring gliders to search for and exploit thermal lift to extend the gliders' endurance. For this purpose, a simple thermal centering controller is proposed. The paper includes theoretical analysis of stability and convergence properties of this controller. Using an exponential Gaussian function to represent the updraft field of a thermal, the Lyapunov type analysis shows the proposed controller to be asymptotically stable and determines its region of attraction. The size of the region of attraction is shown to be a function of the feedback gain that can be adjusted for any given strength and geometry of thermal. The paper additionally presents simulation and flight test results that verify the performance of the proposed controller. The results of the flight trials also confirm the feasibility and effectiveness of using autonomous thermal soaring to extend endurance for unmanned gliders.

AB Objective: To investigate the association between US Navy individual augmentee (IA) deployers, who may lack the protective effects of unit cohesion and social support, and newly reported mental health. Methods: Responses from the Millennium Cohort Study questionnaires were examined for 2086 Navy deployers in this prospective exploratory study. Multivariable logistic regression was used to evaluate IA deployment and newly reported mental health symptoms. Results: After adjusting for covariates, IA deployment was not significantly associated with newly reported posttraumatic stress disorder (odds ratio = 1.02; 95% confidence interval: 0.53-1.95) or mental health symptoms (odds ratio = 1.03; 95% confidence interval: 0.66-1.60) compared with non-IA deployment. Conclusion: IA deployment was not associated with increased risk for posttraumatic stress disorder or mental health symptoms following deployment. It is likely that social isolation was not highly influential among Navy IAs in this study.

PROPAGATION; NUCLEATION; CALIFORNIA
AB We have conducted dynamic rupture propagation experiments to establish the relations between in-source stress drop, fracture energy and the resulting particle velocity during slip of an unconfined 2 m long laboratory fault at normal stresses between 4 and 8 MPa. To produce high fracture energy in the source we use a rough fault that has a large slip weakening distance. An artifact of the high fracture energy is that the nucleation zone is large such that precursory slip reduces fault strength over a large fraction of the total fault length prior to dynamic rupture, making the initial stress non-uniform. Shear stress, particle velocity, fault slip and acceleration were recorded coseismically at multiple locations along strike and at small fault-normal distances. Stress drop increases weakly with normal stress. Average slip rate depends linearly on the fault strength loss and on static stress drop, both with a nonzero intercept. A minimum fracture energy of 1.8 J/m(2) and a linear slip weakening distance of 33 mu m are inferred from the intercept. The large slip weakening distance also affects the average slip rate which is reduced by in-source energy dissipation from on-fault fracture energy.
Because of the low normal stress and small per event slip (similar to 86 mu m), no thermal weakening such as melting or pore fluid pressurization occurs in these experiments. Despite the relatively high fracture energy, and the very low heat production, energy partitioning during these laboratory earthquakes is very similar to typical earthquake source properties. The product of fracture energy and fault area is larger than the radiated energy. Seismic efficiency is low at 2%. The ratio of apparent stress to static stress drop is similar to 27%, consistent with measured overshoot. The fracture efficiency is similar to 33%. The static and dynamic stress drops when extrapolated to crustal stresses are 2-7.3 MPa and in the range of typical earthquake stress drops. As the relatively high fracture energy reduces the slip velocities in these experiments, the extrapolated average particle velocities for crustal stresses are 0.18-0.6 m/s. That these experiments are consistent with typical earthquake source properties suggests, albeit indirectly, that thermal weakening mechanisms such as thermal pressurization and melting which lead to near complete stress drops, dominate earthquake source properties only for exceptional events unless crustal stresses are low.

AB Background Supplemental Nutrition Assistance Program (SNAP) (formerly Food Stamp Program) participants can use their benefits at many farmers' markets. However, most markets have only one market-operated wireless point-of-sale (POS) card swipe terminal for electronic benefits transfer (EBT) transactions. It is not known whether providing each farmer/vendor with individual wireless POS terminals and subsidizing EBT fees will increase SNAP/EBT purchases at farmers' markets.
Objective To evaluate the effects of multiple vendor-operated wireless POS terminals (vs a single market-operated terminal) on use of SNAP benefits at an urban farmers' market.
Design Time-series analyses of SNAP/EBT sales.
Setting The Clark Park farmers' market in West Philadelphia, PA, which accounts for one quarter of all SNAP/EBT sales at farmers' markets in Pennsylvania.
Intervention Vendors were provided with individual wireless PUS terminals for 9 months (June 2008-February 2009.) The pilot program covered all equipment and wireless service costs and transaction fees associated with SNAP/EBT, credit, and debit sales.
Main outcome measure Monthly SNAP/EBT sales at the Clark Park farmers' market.
Statistical analyses SNAP/EBT sales data were collected for 48 months (January 2007-December 2010). Time-series regression analysis was used to estimate the effect of the intervention period (June 2008-February 2009) on SNAP/EBT sales, controlling for seasonal effects and total SNAP benefits issued in Philadelphia.
Results The intervention was associated with a 38% increase in monthly SNAP/EBT sales. Effects were greatest during the busy fall market seasons. SNAP/EBT sales did not remain significantly higher after the intervention period.
Conclusions Providing individual wireless POS terminals to farmers' market vendors leads to increased sales. However, market vendors indicated that subsidies for equipment costs and fees would be needed to break even.

AB We report the discovery of the millisecond pulsar PSR J2043+1711 in a search of a Fermi Large Area Telescope (LAT) source with no known associations, with the Nancay Radio Telescope. The new pulsar, confirmed with the Green Bank Telescope, has a spin period of 2.38 ms, is relatively nearby (d less than or similar to 2 kpc) and is in a 1.48-d orbit around a low-mass companion, probably an He-type white dwarf. Using an ephemeris based on Arecibo, Nancay and Westerbork timing measurements, pulsed gamma-ray emission was detected in the data recorded by the Fermi LAT. The gamma-ray light curve and spectral properties are typical of other gamma-ray millisecond pulsars seen with Fermi. X-ray observations of the pulsar with Suzaku and the Swift X-ray Telescope yielded no detection. At 1.4 GHz, we observe strong flux density variations because of interstellar diffractive scintillation; however, a sharp peak can be observed at this frequency during bright scintillation states. At 327 MHz, the pulsar is detected with a much higher signal-to-noise ratio and its flux density is far more steady. However, at that frequency the Arecibo instrumentation cannot yet fully resolve the pulse profile. Despite that, our pulse time-of-arrival measurements have a post-fit residual rms of 2 mu s. This and the expected stability of this system have made PSR J2043+1711 one of the first new Fermi-selected millisecond pulsars to be added to pulsar gravitational wave timing arrays. It has also allowed a significant measurement of relativistic delays in the times of arrival of the pulses due to the curvature of space-time near the companion, but not yet with enough precision to derive useful masses for the pulsar and the companion. Nevertheless, a mass for the pulsar between 1.7 and 2.0 M-circle dot can be derived if a standard millisecond pulsar formation model is assumed. In this paper, we also present a comprehensive summary of pulsar searches in Fermi LAT sources with the Nancay Radio Telescope to date.

AB PURPOSE: The characteristics of U.S. military personnel who use dietary supplements have not been well described. This study aimed to determine whether deployment experience and physical activity were associated with the use of bodybuilding, energy, or weight-loss supplement among U.S. military personnel.
METHODS: Self-reported data from active-duty, Reserve, and National Guard participants of the Millennium Cohort Study collected from 2007-2008 (n = 106,698) on supplement use, physical activity, and other behavioral data were linked with deployment and demographic data. We used multivariable logistic regression sex-stratified models to compare the adjusted odds of each type of supplement use among those with deployment experience in support of operations in Iraq or Afghanistan and those engaged in aerobic or strength-training activities.
RESULTS: Overall, 46.7% of participants reported using at least one type of supplement, and 22.0% reported using multiple supplements. Male deployers were more likely to use bodybuilding supplements, whereas female deployers were more likely to use weight-loss supplements. Physically active and younger subjects reported all types of supplement use. Men and women reporting 5 or less hours of sleep per night were more likely to use energy supplements.
CONCLUSIONS: The high prevalence of supplement use and important characteristics found to be associated with their use, including deployment, physical activity, and suboptimal sleep, suggest focus areas for future research and adverse event monitoring.

AB Authors in this journal have recommended a new approach to the conduct of biodiversity science. This data-driven approach requires the organization of large amounts of ecological data, analysis of these data to discover complex patterns, and subsequent development of hypotheses corresponding to detected patterns. This proposed new approach has been contrasted with more-traditional knowledge-based approaches in which investigators deduce consequences of competing hypotheses to be confronted with actual data, providing a basis for discriminating among the hypotheses. We note that one approach is directed at hypothesis generation, whereas the other is also focused on discriminating among competing hypotheses. Here, we argue for the importance of using existing knowledge to the separate issues of (a) hypothesis selection and generation and (b) hypothesis discrimination and testing. In times of limited conservation funding, the relative efficiency of different approaches to learning should be an important consideration in decisions about how to study biodiversity.

AB An investigation to determine the stress intensity factor for environmentally assisted cracking (K-EAC) of a large UNS N07725 block forging is described. Displacement-controlled testing was conducted using 1 in thick (25.4 mm) precracked compact tension (CT) specimens machined in the LS (longitudinal-short) and SL (short-longitudinal) orientations.(1) Experiments were carried out under simulated cathodic protection conditions in ASTM D1141 artificial seawater. Test results show that the environmentally assisted cracking threshold of this UNS NO 7725 material exceeds 100 ksi root in (110 MPa root m) under an applied cathodic potential of-1.0 V vs. saturated calomel electrode (SCE), for experiments of approximately 300 h in duration. However, a hydrogen-assisted fracture mode was identified under the more severe testing conditions used.

AB To better describe the genetic diversity of hantaviruses associated with human illness in South America, we screened blood samples from febrile patients in Chapare Province in central Bolivia during 2008-2009 for recent hantavirus infection. Hantavirus RNA was detected in 3 patients, including 1 who died. Partial RNA sequences of small and medium segments from the 3 patients were most closely related to Andes virus lineages but distinct (<90% nt identity) from reported strains. A survey for IgG against hantaviruses among residents of Chapare Province indicated that 12.2% of the population had past exposure to >= 1 hantaviruses; the highest prevalence was among agricultural workers. Because of the high level of human exposure to hantavirus strains and the severity of resulting disease, additional studies are warranted to determine the reservoirs, ecologic range, and public health effect of this novel strain of hantavirus.

AB On-orbit firings of both liquid and solid rocket motors provide localized disturbances to the plasma in the upper atmosphere. Large amounts of energy are deposited to ionosphere in the form of expanding exhaust vapors which change the composition and flow velocity. Charge exchange between the neutral exhaust molecules and the background ions (mainly O+) yields energetic ion beams. The rapidly moving pickup ions excite plasma instabilities and yield optical emissions after dissociative recombination with ambient electrons. Line-of-sight techniques for remote measurements rocket burn effects include direct observation of plume optical emissions with ground and satellite cameras, and plume scatter with UHF and higher frequency radars. Long range detection with HF radars is possible if the burns occur in the dense part of the ionosphere. The exhaust vapors initiate plasma turbulence in the ionosphere that can scatter HF radar waves launched from ground transmitters. Solid rocket motors provide particulates that become charged in the ionosphere and may excite dusty plasma instabilities. Hypersonic exhaust flow impacting the ionospheric plasma launches a low-frequency, electromagnetic pulse that is detectable using satellites with electric field booms. If the exhaust cloud itself passes over a satellite, in situ detectors measure increased ion-acoustic wave turbulence, enhanced neutral and plasma densities, elevated ion temperatures, and magnetic field perturbations. All of these techniques can be used for long range observations of plumes in the ionosphere. To demonstrate such long range measurements, several experiments were conducted by the Naval Research Laboratory including the Charged Aerosol Release Experiment, the Shuttle Ionospheric Modification with Pulsed Localized Exhaust experiments, and the Shuttle Exhaust Ionospheric Turbulence Experiments.

AB This study presents an extension of the ground-based velocity track display (GBVTD)-simplex tropical cyclone (TC) circulation center-finding algorithm to further improve the accuracy and consistency of TC center estimates from single-Doppler radar data. The improved center-finding method determines a TC track that ensures spatial and temporal continuities of four primary characteristics: the radius of maximum wind, the maximum axisymmetric tangential wind, and the latitude and longitude of the TC circulation center. A statistical analysis improves the consistency of the TC centers over time and makes it possible to automate the GBVTD-simplex algorithm for tracking of landfalling TCs. The characteristics and performance of this objective statistical center-finding method are evaluated using datasets from Hurricane Danny (1997) and Bret (1999) over 5-h periods during which both storms were simultaneously observed by two coastal Weather Surveillance Radar-1988 Doppler (WSR-88D) units. Independent single-Doppler and dual-Doppler centers are determined and used to assess the absolute accuracy of the algorithm. Reductions of 50% and 10% in the average distance between independent center estimates are found for Danny and Bret, respectively, over the original GBVTD-simplex method. The average center uncertainties are estimated to be less than 2 km, yielding estimated errors of less than 5% in the retrieved radius of maximum wind and wavenumber-0 axisymmetric tangential wind, and similar to 30% error in the wavenumber-1 asymmetric tangential wind. The objective statistical center-finding method can be run on a time scale comparable to that of a WSR-88D volume scan, thus making it a viable tool for both research and operational use.

AB Endocrine disrupting compounds (EDCs), represented by steroid hormones, organochlorine pesticides (OCPs), polychlorinated biphenyls (PCBs), and bisphenol A have been determined in four sediment cores from the Gulf of Mexico, from New Orleans surface water (Lake Pontchartrain and Mississippi River), and from the influent and effluent of a New Orleans municipal sewage treatment plant. During the five-month monitoring of selected EDCs in the Mississippi River (MR) and Lake Pontchartrain (LP) in 2008, 21 of 29 OCPs in MR and 17 of 29 OCPs in LP were detected; bisphenol A was detected in all of the samples. Steroid hormones (estrone, 17 beta-estradiol and 17 alpha-ethinylestradiol) were detected occasionally. Total EDC (OCPs + PCBs + steroid hormones + bisphenol A) concentrations in the two surface water samples were found to vary from 148 to 1112 ng L-1. Strong correlation of the distribution of total OCPs, total PCBs and total EDCs between solid and water phases was found in LP, while moderate or no correlation existed in MR. OCPs, PCBs, steroid hormones, and bisphenol A were all detected in the ocean sediments, and total EDCs were measured in the range of 77 to 1796 ng g(-1) dry sediment weight. The EDCs were also found in untreated and treated municipal sewage samples with a removal efficiency of 83% for OCPs but no removal efficiency for 17 alpha-ethinylestradiol.

CYCLE; CONVECTION; LAND; CIRCULATION; CLOUD; LAYER
AB Characteristics and dynamics of offshore diurnal waves induced by land sea differential heating are examined using linear theory. Two types of heating profiles are investigated, namely a shallow heating source confined within an atmospheric boundary layer (BL) and a deep heating source located above the boundary layer.
It is demonstrated that a boundary layer top inversion or a more stable layer aloft tends to partially trap diurnal waves in the BL and consequently extend perturbations well offshore. The wave amplitude decays with offshore distance due to BL friction and leakage of energy into the free atmosphere. The dependence of trapped waves on the inversion height and strength, atmosphere stratification, latitude, BL friction, and background winds is investigated. Diurnal waves generated by a deep heating source extending well above the BL are characterized by longer wavelengths, faster propagation, and substantially longer e-folding decay distances than waves induced by a BL source. For the latter, BL friction has little impact on the e-folding decay distance, as waves are mostly located in the free atmosphere rather than in a frictional BL.

AB The large-scale identification and quantitation of proteins via nanoliquid chromatography (LC)-tandem mass spectrometry (MS/MS) offers a unique opportunity to gain unprecedented insight into the microbial composition and biomolecular activity of true environmental samples. However, in order to realize this potential for marine biofilms, new methods of protein extraction must be developed as many compounds naturally present in biofilms are known to interfere with common proteomic manipulations and LC-MS/MS techniques. In this study, we used amino acid analyses (AAA) and LC-MS/MS to compare the efficacy of three sample preparation methods [6 M guanidine hydrochloride (GuHCl) protein extraction + in-solution digestion + 2D LC; sodium dodecyl sulfate (SDS) protein extraction + ID gel LC; phenol protein extraction + 1D gel LC] for the metaproteomic analyses of an environmental marine biofilm. The AAA demonstrated that proteins constitute 1.24% of the biofilm wet weight and that the compared methods varied in their protein extraction efficiencies (0.85-15.15%). Subsequent LC-MS/MS analyses revealed that the GuHCl method resulted in the greatest number of proteins identified by one or more peptides whereas the phenol method provided the greatest sequence coverage of identified proteins. As expected, metagenomic sequencing of the same biofilm sample enabled the creation of a searchable database that increased the number of protein identifications by 48.7% (>= 1 peptide) or 54.7% (>= 2 peptides) when compared to SwissProt database identifications. Taken together, our results provide methods and evidence based recommendations to consider for qualitative or quantitative biofilm metaproteome experimental design.

AB Objective: Cervical cancer remains a leading cause of death in many developing countries because limited screening by Papanicolaou (Pap) smear. We sought to better understand women's beliefs about cervical cancer and screening in Botswana, a middle-income African country with high rates of cervical cancer.
Methods: We interviewed 289 women attending general medicine or human immunodeficiency virus (HIV) clinics, where Pap testing was available, in Gaborone, Botswana, in January 2009.
Results: About three fourths (72%) of the respondents reported having ever had a Pap smear; HIV-positive women were more likely to have had a Pap smear than HIV-negative women (80% vs 64%; odds ratio, 1.97; 95% confidence interval, 1.10-3.55). Screening was also more common among women who were older, had higher incomes, or had heard of cervical cancer. Almost all participants reported a desire to have a Pap smear. Reasons included to determine cervical health (56%), to improve overall health (33%), and to obtain early treatment (34%). About half (54%) of the respondents said they did not know what causes cervical cancer, and almost none attributed the disease to human papillomavirus infection.
Conclusions: Study findings can inform interventions that seek to increase cervical cancer awareness and uptake of screening as it becomes more widely available.

AB Blast-induced traumatic brain injury (TBI) is of significant concern in soldiers returning from the current conflicts in Iraq and Afghanistan. Incidents of TBI have increased significantly in the current conflicts compared to previous wars, and a majority of these injuries are caused by improvised explosive devices. Currently, no specific technique or biomarker is available for diagnosing TBI when no obvious clinical symptoms are present. MicroRNAs are small RNA (similar to 22nts) molecules that are expressed endogenously and play an important role in regulating gene expression. MicroRNAs have emerged as novel serum diagnostic biomarkers for various diseases. In this study, we studied the effect of blast overpressure injury on the microRNA signatures in the serum of rats. Rats were exposed to three serial 120-kPa blast overpressure exposures through a shockwave tube. Blood and cerebrospinal fluid were collected at various time points after injury, and microRNA modulation was analyzed using real-time PCR. Five microRNAs were significantly modulated in the serum samples of these animals at three time points post-injury. Further, we also found that the levels of microRNA let-7i are also elevated in cerebrospinal fluid post-blast wave exposure. The presence of microRNA in both serum and cerebrospinal fluid immediately after injury makes microRNA let-7i an ideal candidate for further studies of biomarkers in TBI.

AB Being able to test for the presence of blood pathogens at forward locations could reduce morbidity and mortality in the field. Rapid, user-friendly blood typing kits for detecting Human Immunodeficiency Virus (HIV), Hepatitis C Virus (HCV), and Hepatitis B Virus (HBV) were evaluated to determine their accuracy after storage at various temperatures/humidities. Rates of positive tests of control groups, experimental groups, and industry standards were compared (Fisher's exact chi(2), p <= 0.05). Compared to the control group, 2 of 10 HIV detection devices were adversely affected by exposure to high temperature/high humidity or high temperature/low humidity. With one exception, none of the environmentally exposed HCV or HBV detection devices exhibited significant differences compared to those stored under control conditions. For HIV, HCV, and HBV devices, there were differences compared to the industry standard. Collectively, this evaluation of pathogen detection kits revealed that diagnostic performance varies among products and storage conditions, and that the tested products cannot be considered to be approved for use to screen blood, plasma, cell, or tissue donors.

TI Persistent Narrowing of Nuclear-Spin Fluctuations in InAs Quantum Dots
Using Laser Excitation
SO PHYSICAL REVIEW LETTERS
LA English
DT Article
ID ELECTRON-SPIN; LOCKING; SPECTROSCOPY
AB We demonstrate the suppression of nuclear-spin fluctuations in an InAs quantum dot and measure the timescales of the spin narrowing effect. By initializing for tens of milliseconds with two continuous wave diode lasers, fluctuations of the nuclear spins are suppressed via the hole-assisted dynamic nuclear polarization feedback mechanism. The fluctuation narrowed state persists in the dark (absent light illumination) for well over 1 s even in the presence of a varying electron charge and spin polarization. Enhancement of the electron spin coherence time (T2*) is directly measured using coherent dark state spectroscopy. By separating the calming of the nuclear spins in time from the spin qubit operations, this method is much simpler than the spin echo coherence recovery or dynamic decoupling schemes.

AB The gamma-ray sky >100MeVis dominated by the diffuse emissions from interactions of cosmic rays with the interstellar gas and radiation fields of the Milky Way. Observations of these diffuse emissions provide a tool to study cosmic-ray origin and propagation, and the interstellar medium. We present measurements from the first 21 months of the Fermi Large Area Telescope (Fermi-LAT) mission and compare with models of the diffuse gamma-ray emission generated using the GALPROP code. The models are fitted to cosmic-ray data and incorporate astrophysical input for the distribution of cosmic-ray sources, interstellar gas, and radiation fields. To assess uncertainties associated with the astrophysical input, a grid of models is created by varying within observational limits the distribution of cosmic-ray sources, the size of the cosmic-ray confinement volume (halo), and the distribution of interstellar gas. An all-sky maximum-likelihood fit is used to determine the X-CO factor, the ratio between integrated CO-line intensity and H-2 column density, the fluxes and spectra of the gamma-ray point sources from the first Fermi-LAT catalog, and the intensity and spectrum of the isotropic background including residual cosmic rays that were misclassified as gamma-rays, all of which have some dependency on the assumed diffuse emission model. The models are compared on the basis of their maximum-likelihood ratios as well as spectra, longitude, and latitude profiles. We also provide residual maps for the data following subtraction of the diffuse emission models. The models are consistent with the data at high and intermediate latitudes but underpredict the data in the inner Galaxy for energies above a few GeV. Possible explanations for this discrepancy are discussed, including the contribution by undetected point-source populations and spectral variations of cosmic rays throughout the Galaxy. In the outer Galaxy, we find that the data prefer models with a flatter distribution of cosmic-ray sources, a larger cosmic-ray halo, or greater gas density than is usually assumed. Our results in the outer Galaxy are consistent with other Fermi-LAT studies of this region that used different analysis methods than employed in this paper.

AB Since the advent of wide-angle imaging of the inner heliosphere, a plethora of techniques have been developed to investigate the three-dimensional structure and kinematics of solar wind transients, such as coronal mass ejections, from their signatures in single- and multi-spacecraft imaging observations. These techniques, which range from the highly complex and computationally intensive to methods based on simple curve fitting, all have their inherent advantages and limitations. In the analysis of single-spacecraft imaging observations, much use has been made of the fixed phi fitting (FPF) and harmonic mean fitting (HMF) techniques, in which the solar wind transient is considered to be a radially propagating point source (fixed phi, FP, model) and a radially expanding circle anchored at Sun centre (harmonic mean, HM, model), respectively. Initially, we compare the radial speeds and propagation directions derived from application of the FPF and HMF techniques to a large set of STEREO/Heliospheric Imager (HI) observations. As the geometries on which these two techniques are founded constitute extreme descriptions of solar wind transients in terms of their extent along the line of sight, we describe a single-spacecraft fitting technique based on a more generalized model for which the FP and HM geometries form the limiting cases. In addition to providing estimates of a transient's speed and propagation direction, the self-similar expansion fitting (SSEF) technique provides, in theory, the capability to estimate the transient's angular extent in the plane orthogonal to the field of view. Using the HI observations, and also by performing a Monte Carlo simulation, we assess the potential of the SSEF technique.

ID ULTIMATE LIMIT
AB We present measurement data of fundamental thermal noise in a 40-m fiber optic Mach-Zehnder interferometer (MZI) using 80-mu m-diameter optical fiber. To extend the measurements to low frequencies (below 500 Hz), the experimental setup is carefully designed to minimize ambient noise, thermal drift, and the phase and amplitude noise of the lasers. These experimental results are compared with theoretical predictions for the magnitude of the fundamental thermal noise in fiber, due to both thermodynamic temperature fluctuations and spontaneous length fluctuations. The experimental data, using two different solid-state lasers with two different emission wavelengths (1319 and 1550 nm), is in reasonable agreement with both theories over frequencies ranging from 20 Hz to 100 kHz. In terms of strain resolution, this paper demonstrates a fundamental thermal noise limit of approximately one femtostrain/rt(Hz) for a 40-m fiber optic MZI.

AB We formulate and solve a set of equations that model the effects of reflections from an arbitrary number of circuit discontinuities in a traveling-wave tube (TWT) operating under small-signal conditions. Applying this model to a case in which the discontinuities represent a series of small random pitch variations due to fabrication errors in a helix TWT, we find that reflections may significantly increase the statistical effects on the gain and output phase first reported in the work of Pengvanich et al. In another example, we report on a study of the effects of many small pitch errors on gain ripple in a 220-GHz folded waveguide TWT.

AB This paper presents development of prototype products for terrestrial ecosystems in preparation for the future imaging spectrometer planned for the Hyperspectral Infrared Imager (HyspIRI) mission. We present a successful demonstration example in a coniferous forest of two product prototypes: fraction of photosynthetically active radiation (PAR) absorbed by chlorophyll of a canopy (fAPAR(chl)) and leaf water content (LWC), for future HyspIRI implementation at 60-m spatial resolution. For this, we used existing 30-m resolution imaging spectrometer data available from the Earth Observing One (EO-1) Hyperion satellite to simulate and prototype the level one radiometrically corrected radiance (L1R) images expected from the HyspIRI visible through shortwave infrared spectrometer. The HyspIRI-like images were atmospherically corrected to obtain surface reflectance and spectrally resampled to produce 60-m reflectance images for wavelength regions that were comparable to all seven of the MODerate resolution Imaging Spectroradiometer (MODIS) land bands. Thus, we developed MODIS-like surface reflectance in seven spectral bands at the HyspIRI-like spatial scale, which was utilized to derive fAPAR(chl) and LWC with a coupled canopy-leaf radiative transfer model (PROSAIL2) for the coniferous forest. With this paper, we provide additional evidence that the fAPAR(chl) product is more realistic in describing the physiologically active canopy than the traditional fAPAR parameter for the whole canopy (fAPAR(canopy)), and thus, it should replace it in ecosystem process models to reduce uncertainties in terrestrial carbon cycle and ecosystem studies.

AB Procalcitonin (PCT) has recently emerged as a powerful biomarker for an early and accurate diagnosis of bacterial infection. Here we summarize our current understanding of the expression pathways of PCT, its potential cellular sources including immune cells, and factors inducing its secretion. Also addressed is the significance of increased blood PCT concentration, which may allow this molecule not only to act as a clinical biomarker but also as an active participant in the development and progression of infectious processes. Experimental approaches to delineate a better understanding of PCT functions, molecular pathways that modulate its expression and therapeutic opportunities to curtail its biological actions are discussed, as well.

AB A group of novel cross-linked polyurethane materials with varying ratios of hydroxyl-terminated macrodiols and tethered quaternary ammonium biocides have been prepared. The resulting materials had a wide range of thermal, mechanical, and surface properties, dictated by the macrodiol composition and biocide concentration. The complex interplay between surface chemistry and biocide concentration was shown to have a profound effect on the fouling resistance of these materials. While the combination of quaternary ammonium salt (QAS) diols with poly(tetramethylene oxide) macrodiols did not result in any enhancement of fouling resistance, addition of biocides to poly(ethylene glycol)-containing urethanes resulted in up to a 90% increase in biocidal activity compared to control materials while reducing the ability for microbes to adhere to the surface by an additional 60%. Materials prepared with polybutadiene macrodiols underwent a thermally induced oxidation, resulting in partial decomposition of the quaternary ammonium salt biocide and joint antimicrobial activity arising from remaining QAS and peroxide compounds.

AB In this paper a model-based approach to identifying a single crack in a thin, clamped plate undergoing free vibration is described and demonstrated experimentally. Data are gathered from only three resistive strain gages, placed at arbitrary orientations and locations far from the crack. The time series response of the gages to a single impact excitation are then used to estimate the crack parameters that characterize the damage using an efficient finite-element model of the plate. The approach is demonstrated effective in identifying crack location, orientation and length, as well as credible intervals for each. The results show that even with limited, noisy vibration data valuable information regarding the damage state can be successfully estimated. (C) 2011 Published by Elsevier Ltd.

AB It has been known for nearly 100 years that pressure unfolds proteins, yet the physical basis of this effect is not understood. Unfolding by pressure implies that the molar volume of the unfolded state of a protein is smaller than that of the folded state. This decrease in volume has been proposed to arise from differences between the density of bulk water and water associated with the protein, from pressure-dependent changes in the structure of bulk water, from the loss of internal cavities in the folded states of proteins, or from some combination of these three factors. Here, using 10 cavity-containing variants of staphylococcal nuclease, we demonstrate that pressure unfolds proteins primarily as a result of cavities that are present in the folded state and absent in the unfolded one. High-pressure NMR spectroscopy and simulations constrained by the NMR data were used to describe structural and energetic details of the folding landscape of staphylococcal nuclease that are usually inaccessible with existing experimental approaches using harsher denaturants. Besides solving a 100-year-old conundrum concerning the detailed structural origins of pressure unfolding of proteins, these studies illustrate the promise of pressure perturbation as a unique tool for examining the roles of packing, conformational fluctuations, and water penetration as determinants of solution properties of proteins, and for detecting folding intermediates and other structural details of protein-folding landscapes that are invisible to standard experimental approaches.

AB Syllogisms are arguments about the properties of entities. They consist of 2 premises and a conclusion, which can each be in 1 of 4 "moods": All A are B, Some A are B, No A are B, and Some A are not B. Their logical analysis began with Aristotle, and their psychological investigation began over 100 years ago. This article outlines the logic of inferences about syllogisms, which includes the evaluation of the consistency of sets of assertions. It also describes the main phenomena of reasoning about properties. There are 12 extant theories of such inferences, and the article outlines each of them and describes their strengths and weaknesses. The theories are of 3 main sorts: heuristic theories that capture principles that could underlie intuitive responses, theories of deliberative reasoning based on formal rules of inference akin to those of logic, and theories of deliberative reasoning based on set-theoretic diagrams or models. The article presents a meta-analysis of these extant theories of syllogisms using data from 6 studies. None of the 12 theories provides an adequate account, and so the article concludes with a guide-based on its qualitative and quantitative analyses-of how best to make progress toward a satisfactory theory.

ID SOCIAL NETWORKS
AB In order to extend the ongoing academic and practitioner dialogs germane to Human, Social, Cultural, and Behavioral (HSCB) modeling and simulation, we introduce a novel extensible methodology for modeling Complex Adaptive Social Systems (CASS) that centers on capturing the emergence of dynamic Beliefs, Values, and Interests (BVIs) in the individuals and groups that compose a whole society. We follow Peter Blau, Miller McPherson, Lynn Smith-Lovin, Duncan Watts and many others in positing that human behavior is best understood in terms of the complex social systems within which actions are taken, and that the representation of these social systems must make evident the endogenous structural constraints on opportunities for interpersonal contact and group affiliation. We further demonstrate that the ability to seed social simulations with representative social data about the society being modeled (e.g. from social surveys), and the use of social networks generated using principles of homophily from empirical social science, provide a compelling and actionable framework for both interpreting with and theory building from whole society simulations.

AB The ancient Babylonians had an iterative technique for numerically approximating the values of square roots. Their method can be physically implemented using series and parallel resistor networks. A recursive formula for the equivalent resistance R-eq is developed and converted into a nonrecursive solution for circuits using geometrically increasing numbers of identical resistors. As an example, 24 resistors R are assembled into a second-order network and R-eq/R is measured to equal root 2 to better than 0.2%, as could be done in an introductory physics laboratory.

AB After the 9.0 magnitude earthquake and subsequent massive tsunami on 11 March 2011 in Japan, several reactors at the Fukushima Daiichi Nuclear Power Plant suffered severe damage. There was immediate participation of U. S. Navy vessels and other United States Department of Defense (DoD) teams that were already in the area at the time of the disaster or arrived shortly thereafter. The correct determination of occupational dose equivalent requires estimation of the background dose component measured by control dosimeters, which is subsequently subtracted from the total dose equivalent measured by personal dosimeters. The purpose of the control dosimeters is to determine the amount of radiation dose equivalent that has accumulated on the dosimeter from background or other nonoccupational sources while they are in transit or being stored. Given the release of radioactive material and potential exposure to radiation from the Fukushima Daiichi Nuclear Power Plant and the process by which the U. S. Navy calculates occupational exposure to ionizing radiation, analysis of pre- and post-event control dosimeters is warranted. Several hundred historical dose records from the Naval Dosimetry Center (NDC) database were analyzed and compared with the post-accident dose equivalent data of control dosimeters. As result, it was shown that the dose contribution of the radiation and released radiological materials from the Fukushima nuclear accident to background radiation doses is less than 0.375 mu Sv d(-1) for shallow and deep photon dose equivalent. There is no measurable effect on neutron background exposure. The latter has at least two important conclusions. First, the NDC can use doses measured by control dosimeters at issuing sites in Japan for determination of personnel dose equivalents; second, the dose data from control dosimeters prior to and after the Fukushima accident may be used to assist in dose reconstruction of non-radiological (non-badged) personnel at these locations.

AB Magnetic hysteresis is one example of the nonlinearity that underpins many practical applications, particularly in the field of magnetic sensors such as fluxgate magnetometers. The aim of this paper is to present a behavioral model that is suitable for the circuital simulation of fluxgate magnetometers in standard simulators like Simulation Program with Integrated Circuit Emphasis (SPICE). The main advantage of the proposed methodology, vis-a-vis the traditional model, is the efficiency in predicting the behavior of amorphous materials with sharp hysteresis loops. Moreover, the developed model is easily implementable in any SPICE-like simulator and can be adopted for a wide range of operating conditions. The modeling strategy has been assessed by the comparison of predicted and observed behaviors of fluxgate magnetometers.

AB Purpose: To assess the impact of increasing experience with intensity-modulated radiation therapy (IMRT) after extrapleural pneumonectomy (EPP) for malignant pleural mesothelioma (MPM). 3
Methods and Materials: The records of all patients who received IMRT following EPP at Duke University Medical Center between 2005 and 2010 were reviewed. Target volumes included the preoperative extent of the pleural space, chest wall incisions, involved nodal stations, and a boost to close/positive surgical margins if applicable. Patients were typically treated with 9-11 beams with gantry angles, collimator rotations, and beam apertures manually fixed to avoid the contalateral lung and to optimize target coverage. Toxicity was graded retrospectively using National Cancer Institute common toxicity criteria version 4.0. Target coverage and contralateral lung irradiation were evaluated over time by using linear regression. Local control, disease-free survival, and overall survival rates were estimated using the Kaplan-Meier method.
Results: Thirty patients received IMRT following EPP; 21 patients also received systemic chemotherapy. Median follow-up was 15 months. The median dose prescribed to the entire ipsilateral hemithorax was 45 Gy (range, 40-50.4 Gy) with a boost of 8-25 Gy in 9 patients. Median survival was 23.2 months. Two-year local control, disease-free survival, and overall survival rates were 47%, 34%, and 50%, respectively. Increasing experience planning MPM cases was associated with improved coverage of planning target volumes (P=.04). Similarly, mean lung dose (P<.01) and lung V5 (volume receiving 5 Gy or more; P<.01) values decreased with increasing experience. Lung toxicity developed after IMRT in 4 (13%) patients at a median of 2.2 months after RT (three grade 3-4 and one grade 5). Lung toxicity developed in 4 of the initial 15 patients vs none of the last 15 patients treated.
Conclusions: With increasing experience, target volume coverage improved and dose to the contralateral lung decreased. Rates of pulmonary toxicity were relatively low. However, both local and distant control rates remained suboptimal. (C) 2012 Elsevier Inc.

AB In this paper the effect of a summer Mistral event on the Ligurian and Tyrrhenian Seas in the northwestern Mediterranean is discussed, using a coupled numerical model and satellite and in situ observations. The focus is on the spatial and temporal distribution of the ocean mixed layer response to the strong winds, and on how this is affected by atmosphere-ocean coupling. The model used is the Coupled Ocean-Atmosphere Mesoscale Prediction System (COAMPS (R) 1), developed at the Naval Research Laboratory. This system includes an atmospheric sigma coordinate, non-hydrostatic model, coupled to a hydrostatic sigma-z level ocean model ( Naval Coastal Ocean Model), using the Earth System Modeling Framework (ESMF). The model is run at high ( km scale) resolution to capture the fine structure of wind jets and surface cooling.
Two non-assimilating numerical experiments, coupled and uncoupled, are run for a 3-day period of a Mistral event, to examine more closely the impact of coupling on the surface flux and sea surface temperature (SST) fields. The cooling of SST up to 3 degrees C over 72 h in the coupled run significantly reduced the surface momentum and heat fluxes, relative to the uncoupled simulation, where the SST was kept fixed at the initial value. Mixed layer depths increase by as much as 30 m during the event. A heat budget analysis for the ocean is carried out to further explain and investigate the SST evolution. Shear-induced mixing in inertial waves is found to be important to the surface cooling. Effects of coupling on the atmospheric boundary layer are found to be significant, but overall the effect of coupling on the synoptic low pressure system is small. (C) 2012 Elsevier Ltd.

ID AD HOC NETWORKS
AB Wireless communication has become omnipresent in the world and enables users to have an unprecedented ability to communicate any time and any place. In this article, we propose a mobility model for studying wireless communication. The model incorporates elements such as users, access points, and obstacles so that it faithfully mimics the real environment. Interesting problems that have practical applications are posed and solved. More specifically, we study the complexity of three problems in a grid. The source reachability problem (SRP) models a situation in which we want to determine whether two access points can communicate at a certain time in a mobile environment. When users are involved in this situation, we call this problem the user communication problem (UCP). We show that SRP can be solved in O(max{d,t}m(2)) time, where d is the number of obstacles, t is the time bound in the statement of the problem, and m is the number of access points; we show that UCP can be solved in O(max{d,t}m(4)) time. The third problem called the user communication, limited source access problem (UCLSAP) studies a situation where we want to determine whether two users can communicate uninterruptedly during the duration of the model while considering battery-time limits of the access points. In contrast to the first two problems, we demonstrate that UCLSAP is intractable, unless P = NP. In conclusion, we briefly discuss the extension of our model to three dimensions and provide a list of open problems. (c) 2012 Wiley Periodicals, Inc. NETWORKS, Vol.59(3), 320-330 2012

SO JOURNAL OF SHIP PRODUCTION AND DESIGN
LA English
DT Article
DE planing; small craft; hydrodynamics
AB In this paper the performance of a stepped planing hull is analyzed through numerical simulation of the fully nonlinear flow under a two-dimensional body. The height and location of the step are systematically varied to investigate the resulting free-surface elevation, pressure profile on the body, and fraction of the total lift that is developed on the downstream portion of the body. The results indicate that indeed a larger step height will generate a larger lift-to-frictional-drag ratio. This suggests that the largest step possible should be chosen, with the upper bound for this dimension being the height in which the flow no longer reattaches to the after-body. The results show that the lift-to-frictional-drag ratio varies very little with respect to the step location over the range studied in this work.

AB Aims To characterize smokeless tobacco initiation and persistence in relation to deployment, combat, occupation, smoking and mental health symptoms. Design Prospective cohort, utilizing self-reported survey data from the Millennium Cohort Study. Setting US military service members in all branches including active duty, reserve and National Guard. Participants Population-based sample of 45 272 participants completing both baseline (July 2001June 2003; n = 77 047) and follow-up (June 2004-January 2006; n = 55 021) questionnaires (follow-up response rate = 71.4%). Measurements Self-reported smokeless tobacco initiation and persistence. Findings Over the study period, 72.4% did not deploy, 13.7% deployed without combat exposures and 13.9% deployed with combat exposures, while 1.9% were smokeless tobacco initiators and 8.9% were persistent users. The odds of initiation were greater for deployers with combat exposure [odds ratio (OR), 1.76; 95% confidence interval (CI), 1.49-2.09], deployers without combat exposure (OR, 1.31; 95% CI, 1.07-1.60) and those who deployed multiple times (OR, 1.67; 95% CI, 1.31-2.14), as well as in smoking recidivists/ initiators (OR, 4.65; 95% CI, 3.82-5.66) and those reporting posttraumatic stress disorder symptoms (OR, 1.54; CI, 1.15-2.07). A similar pattern for higher odds of persistent use was observed for deployment and combat exposure, but not for smoking and mental health symptoms. Military occupation was not significantly associated with initiation or persistence. Conclusions Deployment and combat exposure in the US military are associated with increased risk of smokeless tobacco initiation and persistence while smoking and symptoms of post-traumatic stress disorder increase the odds for initiation. Research is needed on aspects of military service amenable to the reduction or prevention of tobacco consumption.

AB Introduction: Unavailability of blood (and oxygen delivery) for pre-hospital resuscitation in haemorrhagic shock patients are major problems, supporting the importance for novel resuscitation strategies. In a combined polytrauma model of uncontrolled haemorrhage and traumatic brain injury (TBI) in swine, we investigated if pre-hospital administration of the haemoglobin based oxygen carrier HBOC-201 will improve tissue oxygenation and physiologic parameters compared to Lactated Ringer's (LR) solution.
Materials and methods: Anaesthetised Yorkshire swine underwent fluid-percussion TBI and Grade III liver laceration. During a 30-min pre-hospital phase, the animals were resuscitated with a single infusion of HBOC-201, LR solution, or nothing (NON). Upon hospital arrival, the animals were given blood or normal saline as needed. Surviving animals were euthanised 6 h post-injury. Cerebral blood flow was measured by microsphere injection, and pathology was assessed by gross observation and immunohistochemical analysis.
Results: Mean TBI force (2.4 +/- 0.1 atm) (means +/- standard error of the mean) and blood loss (22.5 +/- 1.7 mL/kg) were similar between groups. Survival at the 6 h endpoint was similar in all groups (similar to 50%). Cerebral perfusion pressure (CPP) and brain tissue oxygen tension were significantly greater in HBOC-201 as compared with LR animals (p < 0.005). Mean arterial pressure (MAP) and mean pulmonary artery pressure (MPAP) were not significantly different amongst groups. Blood transfusion requirements were delayed in HBOC-201 animals. Animals treated with HBOC-201 or LR showed no immunohistopathological differences in glial fibrillary acidic protein (GFAP) and microtubule-associated protein 2 (MAP-2). Severity of subarachnoid and intraparenchymal haemorrhages were similar for HBOC and LR groups.
Conclusion: In this polytrauma swine model of uncontrolled haemorrhage and TBI with a 30-min delay to hospital arrival, pre-hospital resuscitation with one bolus of HBOC-201 indicated short term benefits in systemic and cerebrovascular physiological parameters. True clinical benefits of this strategy need to be confirmed on TBI and haemorrhagic shock patients. (C) 2010 Elsevier Ltd. All rights reserved.

We show that the solution exists, and is unique, bounded, nonnegative, and globally defined. We also prove the non-existence of nonconstant steady state solutions if certain conditions are satisfied. For the particular case of two prey (e.g., engineered and native, respectively) and one common predator species, by performing a linear stability analysis about the initial native-dominant steady state, we determine under which conditions the engineered species invasion succeeds.

TI Fluorine functionalization of epitaxial graphene for uniform deposition

AB Fluorine functionalization, using XeF2, was investigated as a way to enhance atomic layer deposition (ALD) of thin, high-kappa dielectrics on epitaxial graphene, which would enable the realization of graphene-based device technologies. The XeF2 dosage time was correlated with oxide coverage and morphology as well as its overall effect on the underlying graphene properties. An optimum XeF2 dose time of 120 s (P-XeF2 = 1 torr, P-N2 = 35 torr) was found to form C-F bonds on 6-7% of the graphene surface, which are presumed to act as additional ALD reaction sites facilitating conformal Al2O3 films only 15 nm thick. Under these optimal conditions, the graphene lattice remained essentially undisturbed and the Hall mobility exhibited a 10-25% increase after oxide deposition. These results indicate that this novel technique is a viable path to obtaining ultrathin high-kappa dielectrics by ALD on epitaxial graphene. (C) 2012 Elsevier Ltd. All rights reserved.

AB Foreign object damage (FOD) phenomena of two gas-turbine grade silicon nitrides (AS800 and SN282) were assessed at ambient temperature applying impact velocities from 20 to 300 m/s using 1.59-mm diameter hardened steel ball projectiles. Targets in a flexural configuration with two different sizes (thicknesses) of 1 and 2 mm were ballistic-impacted under a fully supported condition. The severity of impact damage, as well as the degree of post-impact strength degradation, increased with increasing impact velocity, increased with decreasing target size, and was greater in SN282 than in AS800 silicon nitride. The critical impact velocity where targets fractured catastrophically decreased with decreasing target size and was lower in SN282 than in AS800. Overall, FOD by steel projectiles was significantly less than that by silicon-nitride ceramic counterparts, due to much decreased Hertzian contact stresses. A correlation of backside cracking velocity versus target size was made based on a simplified elastic foundation analysis.

AB The inflammatory response to severe traumatic injury results in significant morbidity and mortality. Lymphocytes have recently been identified as critical mediators of the early innate immune response to ischemia-reperfusion injury. Experimental manipulation of lymphocytes following hemorrhagic shock may prevent secondary immunologic injury in surgical and trauma patients. The objective of this study is to evaluate the lymphocyte sequestration agent FTY720 as an immunomodulator following experimental hemorrhagic shock in a swine liver injury model. Yorkshire swine were anesthetized and underwent a grade III liver injury with uncontrolled hemorrhage to induce hemorrhagic shock. Experimental groups were treated with a lymphocyte sequestration agent, FTY720, (n = 9) and compared to a vehicle control group (n = 9). Animals were observed over a 3 day survival period after hemorrhage. Circulating total leukocyte and neutrophil counts were measured. Central lymphocytes were evaluated with mesenteric lymph node and spleen immunohistochemistry (IHC) staining for CD3. Lung tissue infiltrating neutrophils were analyzed with myeloperoxidase (MPO) IHC staining. Relevant immune-related gene expression from liver tissue was quantified using RT-PCR. The overall survival was 22.2% in the vehicle control and 66.7% in the FTY720 groups (p = 0.081), and reperfusion survival (period after hemorrhage) was 25% in the vehicle control and 75% in the FTY720 groups (p = 0.047). CD3(+) lymphocytes were significantly increased in mesenteric lymph nodes and spleen in the FTY720 group compared to vehicle control, indicating central lymphocyte sequestration. Lymphocyte disruption significantly decreased circulating and lung tissue infiltrating neutrophils, and decreased expression of liver immune-related gene expression in the FTY720 treated group. There were no observed infectious or wound healing complications. Lymphocyte sequestration with FTY720 improves survival in experimental hemorrhagic shock using a porcine liver injury model. These results support a novel and clinically relevant lymphocyte immunomodulation strategy to ameliorate secondary immune injury in hemorrhagic shock.

AB A method for extending charge transfer to bond-order potentials, known as the bond-order potential/split-charge equilibration (BOP/SQE) method [P. T. Mikulski, M. T. Knippenberg, and J. A. Harrison, J. Chem. Phys. 131, 241105 (2009)], is integrated into a new bond-order potential for interactions between oxygen, carbon, and hydrogen. This reactive potential utilizes the formalism of the adaptive intermolecular reactive empirical bond-order potential [S. J. Stuart, A. B. Tutein, and J. A. Harrison, J. Chem. Phys. 112, 6472 (2000)] with additional terms for oxygen and charge interactions. This implementation of the reactive potential is able to model chemical reactions where partial charges change in gas-and condensed-phase systems containing oxygen, carbon, and hydrogen. The BOP/SQE method prevents the unrestricted growth of charges, often observed in charge equilibration methods, without adding significant computational time, because it makes use of a quantity which is calculated as part of the underlying covalent portion of the potential, namely, the bond order. The implementation of this method with the qAIREBO potential is designed to provide a tool that can be used to model dynamics in a wide range of systems without significant computational cost. To demonstrate the usefulness and flexibility of this potential, heats of formation for isolated molecules, radial distribution functions of liquids, and energies of oxygenated diamond surfaces are calculated.

AB The standard teleportation protocol requires the availability of a maximally entangled state. Because such states are difficult to consistently generate experimentally, we study teleportation in which the entanglement used need not be maximal. The relationship between the pure state sent and the mixed state received is shown to define a convex linear, trace preserving, completely positive map on the set of 2 x 2 density operators - in the formal sense of quantum information theory, a qubit channel - and in fact, one whose Bloch representation is diagonal. We then calculate the amount of classical information that can be teleported using a given amount of entanglement. This analysis leads to a remarkable discovery: that the standard measure of entanglement for bipartite states is not correlated with the amount of information that can be teleported using an entangled state.

AB We present a physical Langevin-based theory explaining the emergence and pervasiveness of the following 'fractional motions': Brownian motion, Levy motion, fractional Brownian motion and fractional Levy motion. A general form of micro-level Langevin dynamics, with infinitely many degrees of freedom, is considered. Transcending from the micro-level to the macro-level the infinitely many degrees of freedom collapse to two characteristic exponents, and the aforementioned fractional motions emerge universally. The exponents categorize the fractional motions and determine their statistical and topological properties. The theory establishes a unified 'Langevin bedrock' to fractional motions-which are widely applied prototypical models of random transport in the sciences.

AB Nanostructured, high-surface-area carbon electrodes have large electrochemical double-layer capacitances compared to smooth-surfaced electrodes because of their enhanced internal surface areas, e.g., several hundred m(2)g(-1). In the present work, we demonstrate that the electrical capacitance of carbon "nanofoams", both in commercially available forms and as prepared by the authors, can be significantly enhanced by the insertion into their pores of small Au nanoparticles (similar to 2 nm diameter core) to whose surfaces are bonded ferrocenyl-hexane thiolate ligands (SC6Fc) (>40 per nanoparticle). The enhanced capacitive behavior of the modified nanoporous carbon (in CH3CN or CH2Cl2 with 1.0 or 2.0 M Bu4NPF6 as the supporting electrolyte) is clearly seen in their cyclic voltammetric responses and is attributed to a combination of the ferrocene redox-capacity and the double-layer capacity of the intercalated nanoparticles. Footprint-normalized, volume-normalized, and gravimetric-normalized integral capacitances of 0.28 F cm(-2), 39 F cm(-3), and 66 F g(-1) are realized over a 1 V potential range. We suggest this approach as a conceptual pathway to improve the science of electrochemically based energy storage systems (e.g., "supercapacitors").

AB Background:There are no data on the use of inactivated Vero cell culture-derived Japanese encephalitis (JE) vaccine (JE-VC) as a booster among individuals who previously received inactivated mouse brain-derived JE vaccine (JE-MB).
Methods: Military personnel who received >= 3 doses of JE-MB or were JE vaccine-naive were vaccinated with 2 doses of JE-VC on days 0 and 28. Serum neutralizing antibodies were measured pre-vaccination and 28 days after each dose. Non-inferiority was evaluated for seroprotection rate and geometric mean titer (GMT) between previously vaccinated participants post-dose 1 and vaccine-naive participants post-dose 2.
Results: Fifty-three previously vaccinated and 70 JE vaccine-naive participants were enrolled. Previously vaccinated participants had significantly higher GMTs pre-vaccination, post-dose 1, and post-dose 2. Seroprotection rates among previously vaccinated participants post-dose 1 (44/44, 100%) were noninferior to those achieved in previously naive participants post-dose 2 (53/57, 93%). The GMT was significantly higher in previously vaccinated participants post-dose 1 (GMT 315; 95% CI 191-520) compared to previously naive participants post-dose 2 (GMT 79; 95% CI 54-114).
Conclusions: Among military personnel previously vaccinated with >= 3 doses of JE-MB, a single dose of JE-VC adequately boosts neutralizing antibody levels and provides at least short-term protection. Additional studies are needed to confirm these findings in other populations and determine the duration of protection following a single dose of JE-VC in prior recipients of JE-MB.

It was observed that, as the target decreases in thickness, electron heating by the laser begins to occur for circular polarization leading to target normal sheath acceleration of contaminant ions, while at thicker targets no acceleration or electron heating is observed. For linear polarization, all targets showed exponential energy spreads with similar electron temperatures. Particle-in-cell simulations demonstrate that the heating is due to the rapid deformation of the target that occurs early in the interaction. These experiments demonstrate that finite spot size effects can severely restrict the regime suitable for radiation pressure acceleration.

AB Observations of airglow emission using the RAIDS (Remote Atmospheric and Ionospheric Detection System) instruments on the International Space Station Kibo module are reported and compared to a photochemical model of the emission process. Launched in Sept. 2009, RAIDS performed routine observations of the O-2(b(1)Sigma -> X-3 Sigma) Atmospheric band (O-2 A-band) transition during solar minimum conditions from October 2009 to December 2010. Limb brightness of the (0,0), (0,1) and (1,1) vibration band emissions were measured in the altitude range 80 to 180 km with the Near Infrared Spectrometer (NIRS) instrument, one of eight limb viewing instruments in the RAIDS experiment. Comparison of observed brightness profiles with the model shows very good agreement for the (0,0) and (0,1) bands. The model underestimates the (1,1) brightness profiles throughout the region, especially near the peak. Reasonable variations of composition and selected rate constants do not account for the underestimation of (1,1) band brightness. A contributing factor could be in the assumption of detailed balance and the accepted energy transfer pathways that redistribute energy between the v = 0 and v = 1 states.

AB Polyureas, formed by the rapid reaction between isocyanates and diamines, are attractive for various applications due to their outstanding mechanical properties, which can be tuned by varying component chemistry, molecular weight, and stoichiometry. Polyureas synthesized from a modified methylene diphenyl diisocyanate (Isonate 143 L) and polytetramethylene oxide-di-p-aminobenzoate (Versa link P1000) are widely utilized and investigated for energy absorbing applications such as impact mitigation and ballistic protection. In order to develop a more complete understanding of their mechanical response, we explore the effect of uniaxial strain on the phase separated microstructure and molecular dynamics. We utilize wide- and small-angle X-ray scattering to investigate amorphous segment and hard domain orientation, and broadband dielectric spectroscopy for interrogation of the dynamics. Uniaxial deformation was found to significantly perturb the phase-separated microstructure and chain orientation and result in a considerable slowing down and broadening of the polyurea soft phase segmental relaxation.

AB The contribution of unresolved sources to the diffuse gamma-ray background could induce anisotropies in this emission on small angular scales. We analyze the angular power spectrum of the diffuse emission measured by the Fermi Large Area Telescope at Galactic latitudes vertical bar b vertical bar > 30 degrees in four energy bins spanning 1-50 GeV. At multipoles l >= 155, corresponding to angular scales less than or similar to 2 degrees, angular power above the photon noise level is detected at >99.99% confidence level in the 1-2 GeV, 2-5 GeV, and 5-10 GeV energy bins, and at >99% confidence level at 10-50 GeV. Within each energy bin the measured angular power takes approximately the same value at all multipoles l >= 155, suggesting that it originates from the contribution of one or more unclustered source populations. The amplitude of the angular power normalized to the mean intensity in each energy bin is consistent with a constant value at all energies, C-P/< I >(2) 9.05 +/- 0.84 x 10(-6) sr, while the energy dependence of C-P is consistent with the anisotropy arising from one or more source populations with power-law photon spectra with spectral index Gamma(s) = 2.40 +/- 0.07. We discuss the implications of the measured angular power for gamma-ray source populations that may provide a contribution to the diffuse gamma-ray background.

AB We investigate the properties of a bi-molecular film of liquid crystal close to a magnetic nanoparticle terminated with a variety of functionalization compounds using atomic force microscopy. Studies in bulk liquid crystals have shown that the functionalization compound influences how the liquid crystal reorients. The results of this investigation are compared to the results of work done on phospholipids in close contact with uncovered silica nanoparticles. Our studies of the liquid crystal in contact with the nanoparticles show that its behavior is dependent on the functionalization compound. VC 2012 American Institute of Physics.

TI Flat-fields in DASH interferometry

ID SPATIAL HETERODYNE SPECTROSCOPY; ATMOSPHERE RESEARCH SATELLITE; NM
EMISSION; WIND; DYNAMICS
AB When analyzing the fringe pattern of an interferogram to determine atmospheric wind velocities, inhomogeneities in the optical components and illumination can introduce uncertainty into the results. These variations in the image, which are generally characteristics of the measurement device, are commonly referred to as the "flat-field" of the system. In this work we discuss the effect of this flat-field on measurements made with a Doppler Asymmetric Spatial Heterodyne (DASH) spectrometer. It is found that the flat-field can have a significant effect on any single calculation of the fringe phase, but because the flat-field affects all measurements made with the same system, the uncertainty in the derived wind velocity, which is determined through a comparison of two interferogram fringe phases, typically remains small. Nonetheless, it is recommended to account for the flat-field when analyzing DASH data, if possible. To this end we discuss a method for determining the flat-field using only temperature variations of the system, which is particularly suitable for space-based instruments.

AB Refractory black carbon (rBC) mass and number concentrations were quantified by a Single Particle Soot Photometer (SP2) in the CalNex 2010 field study on board the Center for Interdisciplinary Remotely-Piloted Aircraft Studies (CIRPAS) Twin Otter in the Los Angeles (LA) Basin in May, 2010. The mass concentrations of rBC in the LA Basin ranged from 0.002-0.530 mu g m(-3), with an average of 0.172 mu g m(-3). Lower concentrations were measured in the Basin outflow regions and above the inversion layer. The SP2 afforded a quantification of the mixing state of rBC aerosols through modeling the scattering cross-section with a core-and-shell Mie model to determine coating thickness. The rBC particles above the inversion layer were more thickly coated by a light-scattering substance than those below, indicating a more aged aerosol in the free troposphere. Near the surface, as the LA plume is advected from west to east with the sea breeze, a coating of scattering material grows on rBC particles, coincident with a clear growth of ammonium nitrate within the LA Basin and the persistence of water-soluble organic compounds as the plume travels through the outflow regions. Detailed analysis of the rBC mixing state reveals two modes of coated rBC particles; a mode with smaller rBC core diameters (similar to 90 nm) but thick (>200 nm) coating diameters and a mode with larger rBC cores (similar to 145 nm) with a thin (<75 nm) coating. The "weekend effect" in the LA Basin results in more thickly coated rBC particles, coinciding with more secondary formation of aerosol.

AB Recent Fermi and VERITAS observations of the prototypical Type Ia supernova remnant (SNR) Tycho have discovered gamma-rays with energies E in the range 0.4 GeV less than or similar to E less than or similar to 10 TeV. Crucial for the theory of Galactic cosmic-ray origin is whether the gamma-rays from SNRs are produced by accelerated hadrons (protons and ions) or by relativistic electrons. Here we show that strong constraints on the leptonic model imposed in the framework of the commonly used single-zone model are essentially removed if the analysis of the broadband radiation spectrum of Tycho is done in the two-zone (or, in general, multi-zone) approach, which is likely to apply to every SNR. Importantly, we show that the single-zone approach may underpredict the gamma-ray fluxes by an order of magnitude. A hadronic model can, however, also fit the detected gamma-ray spectrum. The difference between gamma-ray fluxes of hadronic and leptonic origins becomes significant only at less than or similar to 300 MeV, which could be revealed by spectral measurements of Tycho and other SNRs at these energies.

TI Elastic shells with high-contrast material properties as acoustic

DT Article
ID SCATTERING
AB We analyze the acoustic multiple-scattering properties of fluid-filled, elastic cylindrical shells with highly contrasting material properties, and we find for a water background that air-filled shells homogenize into high-bulk modulus, low-density effective fluids. With the exception of a few local resonances spanning very narrow band windows, we find that for common elastic materials the shells are indistinguishable from their effective fluid counterparts for wavelengths larger than the shell's outer diameter. Furthermore, we find that when the elastic shell is composed of a material with impedance larger than water, there will be a specific shell thickness for which the effective fluid properties become impedance-matched. Finally, we demonstrate that the shells can be used as constituent components in regular lattices to create homogenized acoustic metamaterial devices.

GENERATION; NUCLEATION; DEPENDENCE; GAAS(001)
AB The magnetization reversal process within the first two iron layers at the Fe/GaAs(001) interface is found to be different and independent from the Fe thin film bulk as measured by magnetic second-harmonic generation and magneto-optical Kerr effect. The interface magnetization is largely noncollinear from the bulk with an abrupt magnetic boundary and an anisotropic exchange coupling stiffness, weak interlayer coupling but relatively strong intralayer stiffness. In contrast, Fe/GaAs(110) exhibits a rigid coupling between interface and bulk magnetization suggesting that the interfacial bonding structure can dramatically change the nature of the exchange coupling. Moreover, the uniaxial magnetic anisotropy in Fe/GaAs(001) extends from the interface to the first 5 nm in the Fe film and is induced by stress. These results are also relevant to other magnetic/nonmagnetic interfaces with abrupt chemical bond structures.

ID X-RAY INTERFERENCE; THIN-FILMS; CRYSTALLINE OXIDES; STRONTIUM-TITANATE;
SILICON; INTERFACE; GROWTH
AB The epitaxial deposition of oxides on silicon opens the possibility of incorporating their diverse properties into silicon-device technology. Deposition of SrTiO3 on silicon was first reported over a decade ago, but growing the coherent, lattice-matched films that are critical for many applications has been difficult for thicknesses beyond 5 unit cells. Using a combination of density functional calculations and x-ray diffraction measurements, we determine the atomic structure of coherent SrTiO3 films on silicon, finding that the Sr concentration at the interface varies with the film thickness. The structures with the lowest computed energies best match the x-ray diffraction. During growth, Sr diffuses from the interface to the surface of the film; the increasing difficulty of Sr diffusion with film thickness may cause the disorder seen in thicker films. The identification of this unique thickness-dependent interfacial structure opens the possibility of modifying the interface to improve the thickness and quality of metal oxide films on silicon.

AB In 2001, the U.S. Geological Survey, together with several other federal and municipal agencies, began a series of field programs to determine along and cross-shelf transport patterns over the continental shelves in the central Southern California Bight. As a part of these programs, moorings that monitor winds were deployed off the Palos Verdes peninsula and within San Pedro Bay for six 3-4 month summer and winter periods between 2001 and 2008. In addition, nearly continuous records of winds for this 7-year period were obtained from a terrestrial site at the coast and from a basin site offshore of the long-term coastal site. The mean annual winds are downcoast at all sites. The alongshelf components of wind stress, which are the largest part of the low-frequency wind stress fields, are well correlated between basin, shelf and coastal sites. On average, the amplitude of alongshelf fluctuations in wind stress are 3-4 times larger over the offshore basin, compared to the coastal site, irrespective of whether the fluctuations represent the total, or just the correlated portion of the wind stress field. The curl in the large-scale wind stress tends to be positive, especially in the winter season when the mean wind stress is downcoast and larger at the offshore basin site than at the beach. However, since the fluctuation in wind stress amplitudes are usually larger than the mean, periods of weak negative curl do occur, especially in the summer season when the largest normalized differences in the amplitude of wind stress fluctuations are found in the nearshore region of the coastal ocean. Even though the low-frequency wind stress field is well-correlated over the continental shelf and offshore basins, out to distances of 35 km or more from the coast, winds even 10 km inshore of the beach do not represent the coastal wind field, at least in the summer months. The seasonal changes in the spatial structures in wind stress amplitudes suggest that an assessment of the amplitude of the responses of coastal ocean processes to wind forcing is complex and that the responses may have significant seasonal structures.

AB BACKGROUND: The current model of care for individuals with breast cancer focuses on treatment of the disease, followed by ongoing surveillance to detect recurrence. This approach lacks attention to patients' physical and functional well-being. Breast cancer treatment sequelae can lead to physical impairments and functional limitations. Common impairments include pain, fatigue, upper-extremity dysfunction, lymphedema, weakness, joint arthralgia, neuropathy, weight gain, cardiovascular effects, and osteoporosis. Evidence supports prospective surveillance for early identification and treatment as a means to prevent or mitigate many of these concerns. This article proposes a prospective surveillance model for physical rehabilitation and exercise that can be integrated with disease treatment to create a more comprehensive approach to survivorship health care. The goals of the model are to promote surveillance for common physical impairments and functional limitations associated with breast cancer treatment; to provide education to facilitate early identification of impairments; to introduce rehabilitation and exercise intervention when physical impairments are identified; and to promote and support physical activity and exercise behaviors through the trajectory of disease treatment and survivorship.METHODS: The model is the result of a multidisciplinary meeting of research and clinical experts in breast cancer survivorship and representatives of relevant professional and advocacy organizations. RESULTS/CONCLUSIONS: The proposed model identifies time points during breast cancer care for assessment of and education about physical impairments. Ultimately, implementation of the model may influence incidence and severity of breast cancer treatment-related physical impairments. As such, the model seeks to optimize function during and after treatment and positively influence a growing survivorship community. Cancer 2012; 118: (8 Suppl)2191-200.

AB Appropriate and timely rehabilitation is vital in the recovery from breast cancer surgeries, including breast conserving surgery, mastectomy, axillary lymph node dissection (ALND), and breast reconstruction. This article describes the incidence, prevalence, risk factors and time course for early postoperative effects and the role of prospective surveillance as a rehabilitation strategy to prevent and mitigate them. The most common early postoperative effects include wound issues such as cellulitis, flap necrosis, abscess, dehiscence, hematoma, and seroma. Appropriate treatment is necessary to avoid delay in wound healing that may increase the risk of long-term morbidity, unduly postpone systemic and radiation therapy, and delay rehabilitation. The presence of upper quarter dysfunction (UQD), defined as restricted upper quarter mobility, pain, lymphedema, and impaired sensation and strength, has been reported in over half of survivors after treatment for breast cancer. Moreover, evidence suggests that survivors who undergo breast reconstruction may be at higher risk of UQD. Ensuring the survivor's optimum functioning in the early postoperative time period is critical in the overall recovery from breast cancer. The formal collection of objective measures along with patient-reported outcome measures is recommended for the early detection of postoperative morbidity. Prospective surveillance, including preoperative assessment and structured surveillance, allows for early identification and timely rehabilitation. Early evidence supports a prospective approach to address and minimize postoperative effects. Cancer 2012;118(8 suppl):. (c) 2012 American Cancer Society.

AB Cellulose-reinforced composites have received much attention due to their structural reinforcing, light weight, biodegradable, non-toxic, low cost and recyclable characteristics. However, the tendency for cellulose to aggregate and its poor dispersion in many polymers, such as polystyrene, continues to be one of the most challenging roadblocks to large scale production and use of cellulose-polymer composites. In this study, nanofibrillated cellulose (NFC) is modified using GlycidylPhenyl-POSS (a polyhedral oligomeric silsesquioxane). The product yield, morphology, and crystallinity are characterized using a variety of spectroscopy and microscopy techniques. Thermal analyses are performed using thermal gravimetric analysis and pyrolysis combustion flow calorimetry. (C) 2012 Elsevier Ltd. All rights reserved.

AB Microelectrode recording arrays of 60-100 electrodes are commonly used to record neuronal biopotentials, and these have aided our understanding of brain function, development and pathology. However, higher density microelectrode recording arrays of larger area are needed to study neuronal function over broader brain regions such as in cerebral cortex or hippocampal slices. Here, we present a novel design of a high electrode count picocurrent imaging array (PIA), based on an 81,920 pixel Indigo ISC9809 read-out integrated circuit camera chip. While originally developed for interfacing to infrared photodetector arrays, we have adapted the chip for neuron recording by bonding it to microwire glass resulting in an array with an inter-electrode pixel spacing of 30 mu m. In a high density electrode array, the ability to selectively record neural regions at high speed and with good signal to noise ratio are both functionally important. A critical feature of our PIA is that each pixel contains a dedicated low noise transimpedance amplifier (similar to 0.32 pA rms) which allows recording high signal to noise ratio biocurrents comparable to single electrode voltage amplifier recordings. Using selective sampling of 256 pixel subarray regions, we recorded the extracellular biocurrents of rabbit retinal ganglion cell spikes at sampling rates up to 7.2 kHz. Full array local electroretinogram currents could also be recorded at frame rates up to 100 Hz. A PIA with a full complement of 4 readout circuits would span 1 cm and could acquire simultaneous data from selected regions of 1024 electrodes at sampling rates up to 9.3 kHz.

AB Background: Population-based febrile respiratory illness surveillance conducted by the Department of Defense contributes to an estimate of vaccine effectiveness. Between January and March 2011, 64 cases of 2009 A/H1N1 (pH1N1), including one fatality, were confirmed in immunized recruits at Fort Jackson, South Carolina, suggesting insufficient efficacy for the pH1N1 component of the live attenuated influenza vaccine (LAIV).
Methodology/Principal Findings: To test serologic protection, serum samples were collected at least 30 days post-vaccination from recruits at Fort Jackson (LAIV), Parris Island (LAIV and trivalent inactivated vaccine [TIV]) at Cape May, New Jersey (TIV) and responses measured against pre-vaccination sera. A subset of 78 LAIV and 64 TIV sera pairs from recruits who reported neither influenza vaccination in the prior year nor fever during training were tested by microneutralization (MN) and hemagglutination inhibition (HI) assays. MN results demonstrated that seroconversion in paired sera was greater in those who received TIV versus LAIV (74% and 37%). Additionally, the fold change associated with TIV vaccination was significantly different between circulating (2011) versus the vaccine strain (2009) of pH1N1 viruses (ANOVA p value = 0.0006). HI analyses revealed similar trends. Surface plasmon resonance (SPR) analysis revealed that the quantity, IgG/IgM ratios, and affinity of anti-HA antibodies were significantly greater in TIV vaccinees. Finally, sequence analysis of the HA1 gene in concurrent circulating 2011 pH1N1 isolates from Fort Jackson exhibited modest amino acid divergence from the vaccine strain.
Conclusions/Significance: Among military recruits in 2011, serum antibody response differed by vaccine type (LAIV vs. TIV) and pH1N1 virus year (2009 vs. 2011). We hypothesize that antigen drift in circulating pH1N1 viruses contributed to reduce vaccine effectiveness at Fort Jackson. Our findings have wider implications regarding vaccine protection from circulating pH1N1 viruses in 2011-2012.

AB Challenges associated with the allocation of limited resources to mitigate the impact of natural disasters inspire fundamentally new theoretical questions for dynamic decision making in coupled human and natural systems. Wildfires are one of several types of disaster phenomena, including oil spills and disease epidemics, where (1) the disaster evolves on the same timescale as the response effort, and (2) delays in response can lead to increased disaster severity and thus greater demand for resources. We introduce a minimal stochastic process to represent wildfire progression that nonetheless accurately captures the heavy tailed statistical distribution of fire sizes observed in nature. We then couple this model for fire spread to a series of response models that isolate fundamental tradeoffs both in the strength and timing of response and also in division of limited resources across multiple competing suppression efforts. Using this framework, we compute optimal strategies for decision making scenarios that arise in fire response policy.

AB This paper presents a new methodology for identifying defects under the presence of both sensor and defect uncertainties. This methodology introduces a representation of the beliefs of both the locations of defects and the sensors each by a probability density function and updates them using the extended Kalman filter. Because the beliefs are recursively maintained while the sensor is moving and the associated observation data are updated, the proposed approach considers not only the current observation data but also the prior knowledge, the past observation data and beliefs, which include both sensor and defect uncertainties. The concept of differential entropy has been introduced and is utilized as a performance measure to evaluate the result of defect identification and handle the identification of multiple defects. The verification and evaluation of the proposed methodology performance were conducted via parametric numerical studies. The results have shown the successful identification of defects with reduced uncertainty when the number of measurements increases, even under the presence of large sensor uncertainties. Furthermore, the proposed methodology was applied to the more realistic problem of identifying multiple defects located on a specimen and has demonstrated its applicability to practical defect identification problems.

AB The Large Area Telescope on board the Fermi satellite observed a gamma-ray flare in the Crab Nebula lasting for approximately nine days in April of 2011. The source, which at optical wavelengths has a size of approximate to 11 lt-yr across, doubled its gamma-ray flux within eight hours. The peak photon flux was (186 +/- 6) x 10(-7) cm(-2) s(-1) above 100 MeV, which corresponds to a 30-fold increase compared to the average value. During the flare, a new component emerged in the spectral energy distribution, which peaked at an energy of (375 +/- 26) MeV at flare maximum. The observations imply that the emission region was likely relativistically beamed toward us and that variations in its motion are responsible for the observed spectral variability.

AB The spectra of BL Lac objects and Fanaroff-Riley I radio galaxies are commonly explained by the one-zone leptonic synchrotron self-Compton (SSC) model. Spectral modeling of correlated multiwavelength data gives the comoving magnetic field strength, the bulk outflow Lorentz factor, and the emission region size. Assuming the validity of the SSC model, the Hillas condition shows that only in rare cases such sources accelerate protons to much above 10(19) eV, so greater than or similar to 10(20) eV ultra-high-energy cosmic rays (UHECRs) are likely to be heavy ions if powered by this type of radio-loud active galactic nuclei (AGNs). Survival of nuclei is shown to be possible in TeV BL Lacs and misaligned counterparts with weak photohadronic emissions. Another signature of hadronic production is intergalactic UHECR-induced cascade emission, which is an alternative explanation of the TeV spectra of some extreme non-variable blazars such as 1ES 0229+200 or 1ES 1101-232. We study this kind of cascade signal, taking into account effects of the structured extragalactic magnetic fields in which the sources should be embedded. We demonstrate the importance of cosmic-ray deflections on the gamma-ray flux, and show that required absolute cosmic-ray luminosities are larger than the average UHECR luminosity inferred from UHECR observations and can even be comparable to the Eddington luminosity of supermassive black holes. Future TeV gamma-ray observations using the Cerenkov Telescope Array and the High Altitude Water Cerenkov detector array can test for UHECR acceleration by observing >25 TeV photons from relatively low redshift sources such as 1ES 0229+200, and greater than or similar to TeV photons from more distant radio-loud AGNs.

AB We have recently noticed cellular features in Fe XII 193 angstrom images of the 1.2 MK corona. They occur in regions bounded by a coronal hole and a filament channel, and are centered on flux elements of the photospheric magnetic network. Like their neighboring coronal holes, these regions have minority-polarity flux that is similar to 0.1-0.3 times their flux of majority polarity. Consequently, the minority-polarity flux is "grabbed" by the majority-polarity flux to form low-lying loops, and the remainder of the network flux escapes to connect with its opposite-polarity counterpart in distant active regions of the Sun. As these regions are carried toward the limb by solar rotation, the cells disappear and are replaced by linear plumes projecting toward the limb. In simultaneous views from the Solar Terrestrial Relations Observatory and Solar Dynamics Observatory spacecraft, these plumes project in opposite directions, extending away from the coronal hole in one view and toward the hole in the other view, suggesting that they are sky-plane projections of the same radial structures. We conclude that these regions are composed of closely spaced radial plumes, extending upward like candles on a birthday cake and visible as cells when seen from above. We suppose that a coronal hole has this same discrete, cellular magnetic structure, but that it is not seen until the encroachment of opposite-polarity flux closes part or all of the hole.

AB We report the results of a Suzaku X-ray imaging study of NGC 6251, a nearby giant radio galaxy with intermediate FR I/II radio properties. Our pointing direction was centered on the gamma-ray emission peak recently discovered with the Fermi Large Area Telescope (LAT) around the position of the northwest (NW) radio lobe 15 arcmin offset from the nucleus. After subtracting two "off-source" pointings adjacent to the radio lobe and removing possible contaminants in the X-ray Imaging Spectrometer field of view, we found significant residual X-ray emission most likely diffuse in nature. The spectrum of the excess X-ray emission is well fitted by a power law with a photon index Gamma = 1.90 +/- 0.15 and a 0.5-8 keV flux of 4x10(-13) erg cm(-2) s(-1). We interpret this diffuse X-ray emission component as being due to inverse Compton upscattering of the cosmic microwave background photons by ultrarelativistic electrons within the lobe, with only a minor contribution from the beamed emission of the large-scale jet. Utilizing archival radio data for the source, we demonstrate by means of broadband spectral modeling that the gamma-ray flux of the Fermi-LAT source 2FGL J1629.4+8236 may well be accounted for by the high-energy tail of the inverse Compton continuum of the lobe. Thus, this claimed association of gamma-rays from the NW lobe of NGC 6251, together with the recent Fermi-LAT imaging of the extended lobes of Centaurus A, indicates that particles may be efficiently (re-)accelerated up to ultrarelativistic energies within extended radio lobes of nearby radio galaxies in general.

Heating effects are examined as a function of the heating timing and the peak density of the unmodified ionosphere (through the F10.7 index). The simulation results suggest that field-aligned duct formation occur during periods of relatively low electron densities (e. g., during the night). The enhancement of the electron temperature and electron density in the conjugate topside ionosphere (similar to 500 km) could reach respective values of similar to 5% and 25%. Heating losses associated with inelastic electron-neutral (N-2) collisions primarily inhibit conjugate effects. Citation: Wu, T.-W., J. D. Huba, G. Joyce, and P. A.

AB This paper presents a practical method for the development of spectral reflectance libraries under sub-optimal sky conditions. Although there are commercially available spectrometers which simultaneously measure both downwelling and upwelling radiance to mitigate the impact of sub-optimal sky conditions, these spectrometers only record in the visible and near infra-red. There are presently no commercially available spectrometers with this capability that can record the visible through short-wave infra-red. This paper presents a practical method of recording and processing data using coordinated measurements from two full-range spectrometers and discusses potential pitfalls and solutions required to achieve accurate reflectance spectra. Results demonstrate that high-quality spectral reflectance libraries can be developed with this approach. (C) 2012 Optical Society of America

TI Magnetic structure variation in manganese-oxide clusters

DT Article
ID ELECTRONIC-STRUCTURE; MN CLUSTERS; ANIONS
AB Negative-ion photoelectron spectroscopy and ab initio simulations are used to study the variation in magnetic structure in MnxOy (x = 3, 4; y = 1, 2) clusters. The ferrimagnetic and antiferromagnetic ground-state structures of MnxOy are 0.16-1.20 eV lower in energy than their ferromagnetic isomers. The presence of oxygen thus stabilizes low-spin isomers relative to the preferred high-spin ordering of bare Mn-3 and Mn-4. Each cluster has a preferred overall magnetic moment, and no evidence is seen of competing states with different spin multiplicities. However, non-degenerate isomags, which possess the same spin multiplicity but different arrangements of local moments, do contribute additional features and peak broadening in the photoelectron spectra. Proper accounting for all possible isomags is shown to be critical for accurate computational prediction of the spectra. (C) 2012 American Institute of Physics. [http://dx.doi.org/10.1063/1.3698279]

AB The image-state-derived field-emission resonances (FERs) on a Si(111)-(7 x 7) surface that is partially covered by the gold-induced Si(111)-(5 x 2)-Au reconstruction, were probed by scanning tunneling spectroscopy measurements. On Si(111)-(5 x 2)-Au, a shift of the FER peak positions is observed compared to the bare 7 x 7 surface. Spatially resolved dI/dV maps reveal a periodic variation of the higher-order FERs in the direction perpendicular to the chains of the quasi-one-dimensional Si(111)-(5 x 2)-Au reconstruction. The effect appears on a length scale of less than one nanometer and can be attributed to the local surface potential. Simple one-dimensional models reproduce the first seven FERs perfectly and allow extraction of the potential landscape. This landscape is confirmed by density-functional theory calculations, revealing an attractive well above the graphitic Si honeycomb chains due to low electron density.

AB The development of an effective malaria vaccine is a high global health priority. Vaccine vectors based on adenovirus type 5 are capable of generating robust and protective T cell and antibody responses in animal models and are currently being evaluated in clinical trials for HIV and malaria. They appear to be more effective in terms of inducing antigen-specific immune responses as compared with non-Ad5 serotype vectors. However, the high prevalence of neutralizing antibodies to Ad5 in the human population, particularly in the developing world, has the potential to limit the effectiveness of Ad5-based vaccines. We have generated novel Ad5-based vectors that precisely replace the hexon hypervariable regions with those derived from Ad43, a subgroup D serotype with low prevalence of neutralizing antibody in humans. We have demonstrated that these hexon-modified adenovectors are not neutralized efficiently by Ad5 neutralizing antibodies in vitro using sera from mice, rabbits and human volunteers. We have also generated hexon-modified adenovectors that express a rodent malaria parasite antigen, PyCSP, and demonstrated that they are as immunogenic as an unmodified vector. Furthermore, in contrast to the unmodified vector, the hexon-modified adenovectors induced robust T cell responses in mice with high levels of Ad5 neutralizing antibody. We also show that the hexon-modified vector can be combined with unmodified Ad5 vector in prime-boost regimens to induce protective responses in mice. Our data establish that these hexon-modified vectors are highly immunogenic even in the presence of pre-existing anti-adenovirus antibodies. These hexon-modified adenovectors may have advantages in sub-Saharan Africa where there is a high prevalence of Ad5 neutralizing antibody in the population.

AB Large fine mode-dominated aerosols (submicron radius) in size distributions retrieved from the Aerosol Robotic Network (AERONET) have been observed after fog or low-altitude cloud dissipation events. These column-integrated size distributions have been obtained at several sites in many regions of the world, typically after evaporation of low-altitude cloud such as stratocumulus or fog. Retrievals with cloud-processed aerosol are sometimes bimodal in the accumulation mode with the larger-size mode often similar to 0.4-0.5 mu m radius (volume distribution); the smaller mode, typically similar to 0.12 to similar to 0.20 mu m, may be interstitial aerosol that were not modified by incorporation in droplets and/or aerosol that are less hygroscopic in nature. Bimodal accumulation mode size distributions have often been observed from in situ measurements of aerosols that have interacted with clouds, and AERONET size distribution retrievals made after dissipation of cloud or fog are in good agreement with particle sizes measured by in situ techniques for cloud-processed aerosols. Aerosols of this type and large size range (in lower concentrations) may also be formed by cloud processing in partly cloudy conditions and may contribute to the "shoulder" of larger-size particles in the accumulation mode retrievals, especially in regions where sulfate and other soluble aerosol are a significant component of the total aerosol composition. Observed trends of increasing aerosol optical depth (AOD) as fine mode radius increased suggests higher AOD in the near-cloud environment and higher overall AOD than typically obtained from remote sensing owing to bias toward sampling at low cloud fraction.

AB Beginning in 2006, the Indian Ocean experienced climatologically anomalous conditions due to large-scale coupled air-sea interactions that influenced the surface circulation of the equatorial Indian Ocean. Here we present evidence from observations as well as a general circulation model to demonstrate that spring Wyrtki jets (WJ) were weak during the past 6 years and were even reversed to westward flow during 2008. We note that this weakening coincided with uniformly high sea level as well as positive east to west gradient anomalies along the equatorial Indian Ocean during the month of May each year, starting in 2006. The weakened jets occur in conjunction with the latitude of zero zonal wind (LUZ) being close to the equator during these years, resulting in weaker than normal zonal winds along the equator from 2006 and onward. We find that starting in 2006, the normal tendency of westward propagation of the annual harmonic mode switches to eastward propagation, coherent with the wind forcing. In comparison to the annual harmonic component of the zonal current, the weak WJs are mainly associated with the semiannual harmonic WJs, as evident from an amplitude reduction of that mode by at least 0.3 m s(-1) during the post-2005 period. Our analysis demonstrates that the variance explained by the semiannual harmonic is reduced to half (30-40%) at the core of the WJ in 2006 and later years in comparison with earlier years when it was 70-80%.

TI Design and Fabrication of Gecko-Inspired Adhesives
SO LANGMUIR
LA English
DT Article
ID DRY ADHESIVE; ATTACHMENT; FORCE; MODEL
AB Recently, there has been significant interest in developing dry adhesives mimicking the gecko adhesive system, which offers several advantages compared to conventional pressure-sensitive adhesives. Specifically, gecko adhesive pads have anisotropic adhesion properties; the adhesive pads (spatulae) stick strongly when sheared in one direction but are non-adherent when sheared in the opposite direction. This anisotropy property is attributed to the complex topography of the array of fine tilted and curved columnar structures (setae) that bear the spatulae. In this study, we present an easy, scalable method, relying on conventional and unconventional techniques, to incorporate tilt in the fabrication of synthetic polymer-based dry adhesives mimicking the gecko adhesive system, which provides anisotropic adhesion properties. We measured the anisotropic adhesion and friction properties of samples with various tilt angles to test the validity of a nanoscale tape-peeling model of spatular function. Consistent with the peel zone model, samples with lower tilt angles yielded larger adhesion forces. The tribological properties of the synthetic arrays were highly anisotropic, reminiscent of the frictional adhesion behavior of gecko setal arrays. When a 60 tilt sample was actuated in the gripping direction, a static adhesion strength of similar to 1.4 N/cm(2) and a static friction strength of similar to 5.4 N/cm(2) were obtained. In contrast, when the dry adhesive was actuated in the releasing direction, we measured an initial repulsive normal force and negligible friction.

AB An ambidentate dicarboxylic acid bipyridine ligand, (4,5-diazafluoren-9-ylidene) malonic acid (dfm), was synthesized for coordination to Ru(II) and mesoporous nanocrystalline (anatase) TiO2 thin films. The dim ligand provides a conjugated pathway from the pyridyl rings to the carbonyl carbons of the carboxylic acid groups. X-ray crystal structures of [Ru(bpy)(2)(dfm)]Cl-2 and the corresponding diethyl ester compound, [Ru(bpy)(2)(defm)](PF6)(2), were obtained. The compounds displayed intense metal-to-ligand charge transfer (MLCT) absorption bands in the visible region (epsilon > 11,000 M-1 cm(-1) for [Ru(bpy)(2)(dfm)](PF6)(2) in acetonitrile). Significant room temperature photo-luminescence, PL, was absent in CH3CN but was observed at 77 K in a 4:1 EtOH:MeOH (v:v) glass. Cyclic voltammetry measurements revealed quasi-reversible Ru-III/(II) electrochemistry. Ligand reductions were quasi-reversible for the diethyl ester compound [Ru(bpy)(2)(defm)](2+), but were irreversible for [Ru(bpy)(2)(dfm)](2+). Both compounds were anchored to TiO2 thin films by overnight reactions in CH3CN to yield saturation surface coverages of 3 X 10(-8) mol/cm(2). Attenuated total reflection infrared measurements revealed that the [Ru(bpy)(2)(dfm)](2+) compound was present in the deprotonated carboxylate form when anchored to the TiO2 surface. The MLCT excited states of both compounds injected electrons into TiO2 with quantum yields of 0.70 in 0.1 M LiClO4 CH3CN. Micro- to milli- second charge recombination yielded ground state products. In regenerative solar cells with 0.5 M LiI/0.05 M I-2 in CH3CN, the Ru(bpy)(2)(dfm)/TiO2 displayed incident photon-to-current efficiencies of 0.7 at the absorption maximum. Under the same conditions, the diethylester compound was found to rapidly desorb from the TiO2 surface.

AB Fe/Zr-codoped In2O3 thin films were grown on yttria stabilized zirconia substrates by pulsed laser deposition. The deposited films exhibited ferromagnetism at room temperature with strong magnetic anisotropy, which was influenced by a magnetostriction effect under tensile stress (i.e., c/a > 1). Both the saturation magnetization and anomalous Hall effect (AHE) were enhanced by increasing charge carrier density via Zr-doping. Our observations, including AHE and magnetic anisotropy, provide strong evidence of intrinsic ferromagnetism at room temperature in these materials. (C) 2012 American Institute of Physics.

ID PASSIVATION; CAPACITORS; PARAMETERS; GAAS
AB Performance degradation due to interfacial traps is generally considered as one of the main challenges for III-V metal-oxide-semiconductor field-effect-transistors (MOSFETs). In this work, we have investigated the suppression of interface state response using band engineering in III-V quantum well MOSFETs and experimentally verified the concept in the antimonide materials system using a gate-stack consisting of Al2O3/GaSb/InAlSb. It is shown that if the thickness of the interfacial layer of GaSb is scaled down to a few monolayers, the effective bandgap of the interfacial layer increases dramatically due to quantum confinement, which leads to the suppression of interface-trap response.

AB The measured spectrum of kinetic Alfven wave fluctuations in the turbulent solar wind plasma is used to calculate the quasi-linear evolution of the initially stable electron and ion distribution functions. The resulting ion distribution function is found to be unstable to electromagnetic left hand polarized ion cyclotron-Alfven waves as well as right hand polarized magnetosonic-whistler waves. These waves can pitch angle scatter the ion super-thermal velocity component to provide perpendicular ion heating. Additionally, right hand polarized waves transfer some part of kinetic Alfven wave flux to whistler waves. (C) 2012 American Institute of Physics. [http://dx.doi.org/10.1063/1.3698407]

AB Smoke deposition patterns are a potentially rich source of information concerning the behavior of a fire. Clean burn patterns are smoke-free areas where smoke deposits have been oxidized away. In order to predict the formation of clean burn patterns, smoke oxidation kinetics are required. Smoke oxidation kinetics were studied for smokes from acrylonitrile butadiene styrene, polymethylmethacrylate, polypropylene, and gasoline. The fuels were burned below a hood, and smoke samples were collected from the hot gas layer and from the wall surfaces. The smokes from various polymers and gasoline were found to contain no measurable volatile organic chemicals. The kinetics of the smokes from the polymers and gasoline were found to be satisfactorily modeled as first order in both smoke and oxygen with the same kinetic constants for all fuels tested. The activation energy was calculated to be 211 kJ/mol, and the pre-exponential factor was found to be 4.7 x 10(10)/s. These kinetic parameters provide a basis for modeling clean burn pattern generation. Copyright (C) 2011 John Wiley & Sons, Ltd.

AB Using direct-tunable diode laser absorption spectroscopy, we obtained simultaneous oxygen, water vapor, and temperature measurements in situ during aqueous high expansion foam-suppressed fires in a foam-adapted cup burner apparatus. Foams with expansion ratios ranging from 55:1 to 129:1 were delivered at various rates; measurements were obtained 5.5 cm above and 1.5 cm outside the cup burner exit. By monitoring water vapor as foam advances through the cup burner chimney with and without the flame present, we are able to quantify evaporation due to the presence of the thermal and radiating field. We are also able to measure the impact on the oxygen concentration resulting from flame consumption of oxygen versus release of oxygen from evaporating foam bubbles. By analyzing video captured during each foam injection event, foam velocities during fire suppression and in the absence of the flame were measured.

AB The structure and propagation of oceanic Yanai waves (also known as mixed Rossbygravity waves) are investigated by analysis of satellite-derived sea-surface-height (SSH) data. Significant spectral peaks along the dispersion curves of first and second baroclinic mode Yanai waves are identified by the wavenumberfrequency spectral analysis of SSH for the period 1017 days. The spatial structure and propagation of these modes are described by an analysis of SSH time series filtered in the frequencywavenumber domain that includes strong signals along the dispersion curves but excludes those of 17-day tropical instability waves. The difference in meridional structure between the first and second baroclinic modes, which is consistent with theory, is evident. The slow eastward propagation of first and second baroclinic mode Yanai wave packets, which is consistent with the group velocity derived from theory, is also isolated from the SSH data. Year-to-year variability of Yanai wave activity is compared with that of the El NinoSouthern Oscillation (ENSO), showing a moderate correlation with ENSO Modoki.

AB A fully coupled multi-dimensional continuum model of the thermoelectromechanics of GaN HEMTs is presented and discussed. The governing equations are those of linear thermoelectroelasticity, diffusion-drift transport theory, and heat conduction, with full coupling assumed, i.e., all mechanical, electrical, and thermal variables are solved for simultaneously. Apart from the known strains induced by epitaxy, plane-strain conditions are assumed, so that two-dimensional simulation suffices. Important aspects of the model are that it incorporates "actual" device geometries and that it captures field/stress concentrations that often occur near material discontinuities and especially at corners. The latter are shown to be especially important with regards to understanding the mechanisms of both electrical and mechanical degradation in GaN HEMTs. Various possible contributors to degradation are discussed, including electron injection, the inverse piezoelectric effect, thermal stress, SiN intrinsic stress, and device geometry. The possibilities of crack propagation and fracture of the AlGaN are also analyzed. [http://dx.doi.org/10.1063/1.3698492]

AB A series of alloys with compositions of Nd4+xFe72Co5Ga2B17-x, where x = 0-10, were prepared by rapid solidification. Annealing the as-spun alloys above primary crystallization (T-x1) formed nanocomposite ribbons. While x-ray diffraction measurements showed the annealed alloys to be nanocrystalline, the phases present in each alloy were found to vary with Nd content. The alloys with x = 0, 7.5, and 10 contained a majority fraction of the Nd2Fe14B phase, along with Fe3B, alpha-Fe, and/or Nd2Fe23B3 phases. These alloys showed room temperature coercivities and remanent magnetizations of 199, 446, and 1034 kA/m and 120, 82, and 70 A m(2)/kg, respectively. The x = 5 and 7.5 samples were primarily made up of Nd2Fe23B3, and therefore, showed little coercivity. At elevated temperatures, the presence of Co and Ga were found to increase the coercivity of the Nd2Fe14B phase. (C) 2012 American Institute of Physics. [doi:10.1063/1.3673810]

ID ALLOYS
AB An attractive feature of the Galfenol alloy system is the ability to impart enough uniaxial anisotropy into the alloy such that no pre-load mechanism is required to attain saturation magnetostriction. Stress annealing is typically employed to generate this anisotropy. Recent published results indicate that magnetic field annealing could generate sufficient anisotropy to provide full magnetostriction with no prestress, which will suffice for the majority of applications. The magnetic field annealing apparatus used in these experiments applies a constant 1T magnetic field at a temperature between 300 degrees C and 700 degrees C in a 7.6cm square x 15.2-cm-long cavity. The magnetic behavior of field-annealed Galfenol is compared to stress-annealed samples. Field-annealed Galfenol rods behave differently than stress-annealed rods. While the saturation strain values are equivalent, the magnetic field required to saturate the Galfenol is much less, 60 Oe versus 200 Oe, in the field-annealed state. This behavior is also exhibited in the flux density versus field. Both curves have a significant impact on device design. The type (mechanical or magnetic) and magnitude of stored energy largely determines the optimum magnetic bias point and impacts operational efficiency. (C) 2012 American Institute of Physics.

AB Nanocomposite ribbons with composition Pr-10(Fe1-2xCoxNix)(84)B-6 (x=0.0, 0.05, 0.10, and 0.15) were prepared by melt-spinning. All melt-spun ribbons are composed of a fine mixture of 2: 14: 1 and bcc-(Fe,Co,Ni) phases with an additional soft phase (Pr2Fe23B3-based) for x=0.10 and 0.15. The room temperature coercivity decreases from 7.4 to 2 kOe with Co and Ni substitutions likely due to the decrease of the magnetocrystalline anisotropy of the 2: 14: 1 phase and the increase of the amount of the soft phases. Saturation magnetization increases slightly while remanence and (BH)(max) show a slight decrease for x up to 0.10 and then they drop quickly. The intergranular exchange coupling is strong for x <= 0.10 but it is reduced significantly for x=0.15 due to the substantial increase of the volume and size of the soft phases. Thermomagnetic measurements showed a significant increase of the Curie temperature of the 2: 14: 1 phase from 290 degrees C for x 0 to 485 degrees C for x=0.15. High temperature hysteresis loop measurements showed improved temperature dependence of remanence and coercivity for x=0.05. (C) 2012 American Institute of Physics. [doi:10.1063/1.3676233]

AB Tetragonal magnetostriction (lambda(gamma,2)) and elastic constants (c', c(44), and c(11)) for Fe100-xSix were measured as a function of temperature (T). Compositions corresponding to the disordered A2 (x = 5), ordered D0(3) (x = 19.8), and mixed (x = 11.6) phases, were investigated. The magnetoelastic coupling (-b(1)) was determined for 77 < T < 300 K and compared with those of Fe-Ga, Fe-Ge, and Fe-Al. Both lambda(gamma,2) (T) and -b(1)(T) of Fe-Si behave similarly to those of Fe-Ge, while other notable differences exist between the measured properties of Fe-Si and those of the other three alloys. Due to the early establishment of short range order, Fe-Si exhibits a positive, although small, slope in lambda(gamma,2) (T) at 5 at. % Si, and a remarkable drop in -b(1) before the solubility limit. The weaker softening of the tetragonal shear modulus with the addition of Si and the lack of strong anharmonic effects in the Fe-Si lattice inferred from the weak T-dependence of all the moduli suggest that Fe-Si exhibits more structural stability than the other three alloys. The distinctive behavior is likely due to the smaller size of Si compared to the sizes of Ga, Ge and Al, and therefore to the effect of the larger size difference between Fe and Si in the Fe-Si lattice.

AB Samples of rice husks were transformed to beta (3C)-SiC by microwave processing in controlled conditions of temperature and vacuum. This simple and fast way of producing powdered samples of silicon carbide is technologically important if this material is to be used for electronics, sensors, biotechnology, and other applications. Using x-ray diffraction it was found that the microwave processed sample at 1900 degrees C consists of beta (3C)-SiC phase. Raman scattering measurements confirmed the formation of beta (3C)-SiC phase. Transmission electron microscopy revealed the presence of stacking faults along the [111] direction. The presence of 6H/4H stacking faults in 3C phase is explained in terms of their total energies. The presence of these stacking faults with a similar to 1 eV band offset between the host 3C and hexagonal stacking faults implies that these stacking faults provide a conduction barrier, and the interfaces between the stacking faults and host lattice act as a heterojunction that may provide potential utility for various optoelectronic applications.

AB The magnetic field plays a pivotal role in many fields of Astrophysics. This is especially true for the physics of the solar atmosphere. Measuring the magnetic field in the upper solar atmosphere is crucial to understand the nature of the underlying physical processes that drive the violent dynamics of the solar corona-that can also affect life on Earth. SolmeX, a fully equipped solar space observatory for remote-sensing observations, will provide the first comprehensive measurements of the strength and direction of the magnetic field in the upper solar atmosphere. The mission consists of two spacecraft, one carrying the instruments, and another one in formation flight at a distance of about 200 m carrying the occulter to provide an artificial total solar eclipse. This will ensure high-quality coronagraphic observations above the solar limb. SolmeX integrates two spectro-polarimetric coronagraphs for off-limb observations, one in the EUV and one in the IR, and three instruments for observations on the disk. The latter comprises one imaging polarimeter in the EUV for coronal studies, a spectro-polarimeter in the EUV to investigate the low corona, and an imaging spectro-polarimeter in the UV for chromospheric studies. SOHO and other existing missions have investigated the emission of the upper atmosphere in detail (not considering polarization), and as this will be the case also for missions planned for the near future. Therefore it is timely that SolmeX provides the final piece of the observational quest by measuring the magnetic field in the upper atmosphere through polarimetric observations.

TI Assessing Moonlight Availability for Nighttime Environmental
Applications by Low-Light Visible Polar-Orbiting Satellite Sensors
SO JOURNAL OF ATMOSPHERIC AND OCEANIC TECHNOLOGY
LA English
DT Article
ID IMAGERY
AB The next-generation U.S. polar-orbiting environmental satellite program, the Joint Polar Satellite System (JPSS), promises unprecedented capabilities for nighttime remote sensing by way of the day/night band (DNB) low-light visible sensor. The DNB will use moonlight illumination to characterize properties of the atmosphere and surface that conventionally have been limited to daytime observations. Since the moon is a highly variable source of visible light, an important question is where and when various levels of lunar illumination will be available. Here, nighttime moonlight availability was examined based on simulations done in the context of Visible/Infrared Imager Radiometer Suite (VIIRS)/DNB coverage and sensitivity. Results indicate that roughly 45% of all JPSS-orbit [sun-synchronous, 1330 local equatorial crossing time on the ascending node (LTAN)] nighttime observations in the tropics and midlatitudes would provide levels of moonlight at crescent moon or greater. Two other orbits, 1730 and 2130 LTAN, were also considered. The inclusion of a 2130 LTAN satellite would provide similar availability to 1330 LTAN in terms of total moonlit nights, but with approximately a third of those nights being additional because of this orbit's capture of a different portion of the lunar cycle. Nighttime availability is highly variable for near-terminator orbits. A1-h shift from the 1730 LTAN near-terminator orbit to 1630 LTAN would nearly double the nighttime availability globally from this orbit, including expanded availability at midlatitudes. In contrast, a later shift to 1830 LTAN has a negligible effect. The results are intended to provide high-level guidance for mission planners, algorithm developers, and various users of low-light applications from these future satellite programs.

TI Optimizing Provider Recruitment for Influenza Surveillance Networks
SO PLOS COMPUTATIONAL BIOLOGY

DT Article
ID EPIDEMIC; PREDICTION; SPREAD
AB The increasingly complex and rapid transmission dynamics of many infectious diseases necessitates the use of new, more advanced methods for surveillance, early detection, and decision-making. Here, we demonstrate that a new method for optimizing surveillance networks can improve the quality of epidemiological information produced by typical provider-based networks. Using past surveillance and Internet search data, it determines the precise locations where providers should be enrolled. When applied to redesigning the provider-based, influenza-like-illness surveillance network (ILINet) for the state of Texas, the method identifies networks that are expected to significantly outperform the existing network with far fewer providers. This optimized network avoids informational redundancies and is thereby more effective than networks designed by conventional methods and a recently published algorithm based on maximizing population coverage. We show further that Google Flu Trends data, when incorporated into a network as a virtual provider, can enhance but not replace traditional surveillance methods.

TI Three-dimensional transport imaging for the spatially resolved
determination of carrier diffusion length in bulk materials
SO REVIEW OF SCIENTIFIC INSTRUMENTS
LA English
DT Article
ID LIFETIME
AB A contact-free optical technique is developed to enable a spatially resolved measurement of minority carrier diffusion length and the associated mobility-lifetime (mu tau) product in bulk semiconductor materials. A scanning electron microscope is used in combination with an internal optical microscope and imaging charge-coupled device (CCD) to image the bulk luminescence from minority carrier recombination associated with one-dimensional excess carrier generation. Using a Green's function to model steady-state minority carrier diffusion in a three-dimensional half space, non-linear least squares analysis is then applied to extract values of carrier diffusion length and surface recombination velocity. The approach enables measurement of spatial variations in the mu tau product with a high degree of spatial resolution. [http://dx.doi.org/10.1063/1.3698090]

AB Optical trapping forces depend on the difference between the trap wavelength and the extinction resonances of trapped particles. This leads to a wavelength-dependent trapping force, which should allow for the optimization of optical tweezers systems, simply by choosing the best trapping wavelength for a given application. Here we present an optical tweezer system with wavelength tunability, for the study of resonance effects. With this system, the optical trap stiffness is measured for single trapped particles that exhibit either single or multiple extinction resonances. We include discussions of wavelength-dependent effects, such as changes in temperature, and how to measure them. [http://dx.doi.org/ 10.1063/1.4704373]

AB In the pursuit of novel, laser-produced x-ray sources for medical imaging applications, appropriate instrumental diagnostics need to be developed concurrently. A type of transmission crystal spectroscopy has previously been demonstrated as a survey tool for sources produced by high-power and high-energy lasers. The present work demonstrates the extension of this method into the study of medium-intensity laser driven hard x-ray sources with a design that preserves resolving power while maintaining high sensitivity. Specifically, spectroscopic measurements of characteristic K alpha and K beta emissions were studied from Mo targets irradiated by a 100 fs, 200 mJ, Ti: sapphire laser with intensity of 10(17) W/cm(2) to 10(18) W/cm(2) per shot. Using a transmission curved crystal spectrometer and off-Rowland circle imaging, resolving powers (E/Delta E) of around 300 for Mo K alpha(2) at 17.37 keV were obtained with an end-to-end spectrometer efficiency of (1.13 +/- 0.10) x 10 (5). This sensitivity is sufficient for registering x-ray lines with high signal to background from targets following irradiation by a single laser pulse, demonstrating the utility of this method in the study of the development of medium-intensity laser driven x-ray sources.

AB The mechanical properties and corrosion resistance of duplex (ferrite-austenite) grade 2205 stainless steel have been substantially improved by interstitial hardening using low temperature carburisation. The austenite phase of the duplex stainless steel responds to low temperature carburisation in a similar manner as single phase austenitic stainless steels, forming 'expanded' austenite (also called S phase). The surface layer that forms on the ferritic portion of 2205 steel consists of a paraequilibrium carbide, a carbide with the same metal composition as the underlying ferrite. This two-phase case has about three times the Vickers hardness of non-treated material, an improved ultimate tensile strength and increased fatigue resistance, and much improved crevice corrosion resistance.

AB We present the second catalog of high-energy gamma-ray sources detected by the Large Area Telescope (LAT), the primary science instrument on the Fermi Gamma-ray Space Telescope (Fermi), derived from data taken during the first 24 months of the science phase of the mission, which began on 2008 August 4. Source detection is based on the average flux over the 24 month period. The second Fermi-LAT catalog (2FGL) includes source location regions, defined in terms of elliptical fits to the 95% confidence regions and spectral fits in terms of power-law, exponentially cutoff power-law, or log-normal forms. Also included are flux measurements in five energy bands and light curves on monthly intervals for each source. Twelve sources in the catalog are modeled as spatially extended. We provide a detailed comparison of the results from this catalog with those from the first Fermi-LAT catalog (1FGL). Although the diffuse Galactic and isotropic models used in the 2FGL analysis are improved compared to the 1FGL catalog, we attach caution flags to 162 of the sources to indicate possible confusion with residual imperfections in the diffuse model. The 2FGL catalog contains 1873 sources detected and characterized in the 100 MeV to 100 GeV range of which we consider 127 as being firmly identified and 1171 as being reliably associated with counterparts of known or likely gamma-ray-producing source classes.

AB Background
Most previous attempts to determine the psychological cost of military deployment have been limited by reliance on convenience samples, lack of pre-deployment data or confidentiality and cross-sectional designs.
Aims
This study addressed these limitations using a population-based, prospective cohort of US military personnel deployed in support of the operations in Iraq and Afghanistan. Method The sample consisted of US military service members in all branches including active duty, reserve and national guard who deployed once (n=3393) or multiple times (n=4394). Self-reported symptoms of post-traumatic stress were obtained prior to deployment and at two follow-ups spaced 3 years apart. Data were examined for longitudinal trajectories using latent growth mixture modelling.
Results
Each analysis revealed remarkably similar post-traumatic stress trajectories across time. The most common pattern was low-stable post-traumatic stress or resilience (83.1% single deployers, 84.9% multiple deployers), moderate-improving (8.0%, 8.5%), then worsening-chronic post-traumatic stress (6.7%, 4.5%), high-stable (2.2% single deployers only) and high-improving (2.2% multiple deployers only). Covariates associated with each trajectory were identified.
Conclusions
The final models exhibited similar types of trajectories for single and multiple deployers; most notably, the stable trajectory of low post-traumatic stress pre- to post-deployment, or resilience, was exceptionally high. Several factors predicting trajectories were identified, which we hope will assist in future research aimed at decreasing the risk of post-traumatic stress disorder among deployers.

AB A simple three-step synthesis of 5-(3-hydroxyphenyl)-2-methyl-2-azabicyclo[3.3.1]nonan-4-ol (3a) was achieved using an osmium tetroxide mediated oxidation of the known intermediate 6. A pyrrolidine-ring variant of 3a (3-(7-(hydroxymethyl)-6-methyl-6-azabicyclo[3.2.1]octan-1-yl)phenol (5)) was isolated when other routes were used. The epimeric hydroxy analogue 4a was synthesized by simple inversion of the stereochemistry at C-4. Both N-methyl (3a and 4a) and N-phenethyl (3b and 4b) derivatives were synthesized. The compounds were examined for their opioid receptor affinity and the N-phenethyl analogue 3b was found to have relatively weak affinity for the mu-opioid receptor (K-i = 74 nM). However, the N-phenethyl analogue of the C-4 epimer, 4b, had about 15 fold higher affinity than 3b and was selective for the mu-opioid receptor (K-i = 4.6 nM). Compound 4b was a moderately potent mu-opioid antagonist (K-e = 12 nM), as determined by [S-35]GTP-gamma-S assays. Compounds 3b and 4b were energy minimized at the level of B3LYP/6-31G*, and then overlaid onto the 5-phenylmorphan, the (1R,5R,9S)-(-)-enantiomer of 2b (Fig. 1) with the alpha or beta-OH group at the C-9 position. The spatial orientation of the hydroxyl moiety in 3b, 4b, 2a, and 2b is proposed to be the structural requirement for high p-opioid receptor binding affinity and their agonist or antagonist activity. The modest change in spatial position of the hydroxyl moiety, and not the N-substituent, induced the change from potent agonist to an antagonist of moderate potency. Published by Elsevier Masson SAS.

AB The dynamic tree (DT) graphical model is a popular analytical tool for image segmentation and object classification tasks. A DT is a useful model in this context because its hierarchical property enables the user to examine information in multiple scales and its flexible structure can more easily fit complex region boundaries compared to rigid quadtree structures such as tree-structured Bayesian networks. This paper proposes a novel framework for data fusion called a deformable Bayesian network (DFBN) by using a DT model to fuse measurements from multiple sensing platforms into a nonredundant representation. The structural flexibility of the DFBN will be used to fuse common information across different sensor measurements. The appropriate structure update strategies for the DFBN and its parameters for the data fusion application are discussed. A real-world example application using sonar images collected from a survey mission is presented. The fusion results using the presented DFBN framework are shown to outperform state-of-the-art approaches such as the Gaussian mean shift and spectral clustering algorithms. The DFBN's complexity and scalability are discussed to address its potential for a larger data set.

AB 20R,21R-Epoxyresibufogenin-3-formate (1) and 20S,21S-epoxyresibufogenin-3-formate (2) were synthesized from commercial resibufogenin (3) using known procedures. The major product (1) was dextrorotatory, as was the major product from the reported synthesis of epoxyresibufogenin-3-formate; however, the literature (+)-compound was assigned the 20S,21S-configuration on the basis of NMR data. We have now unequivocally determined, using single-crystal X-ray structure analyses of the major and minor products of the synthesis and of their derivatives, that the major product from the synthesis was (+)-20R,21R-epoxyresibufogenin-3-formate (1). Our minor synthetic product was determined to have the (-)-20S,21S-configuration (2). The (+)-20R,21R-compound 1 has been found to have high affinity for the IL-6 receptor and to act as an IL-6 antagonist. A greatly improved synthesis of 1 was achieved through oxidation of preformed resibufogenin-3-formate. This has enabled us to prepare, from the very expensive commercial resibufogenin, considerably larger quantities of 1, the only known nonpeptide small-molecule IL-6 antagonist.

AB Alcohol prevention strategies for soldiers in sub-Saharan African countries suffer from limited knowledge about soldiers' alcohol consumption patterns. The present study was conducted to understand such patterns in Angolan soldiers, including associated risk and protective factors. From 12 military bases, 568 soldiers completed structured interviews that assessed demographic information, level of alcohol consumption, mental health, social support and religious activity. Logistic regressions were used to determine factors associated with any alcohol intake, problematic drinking, binge drinking and alcohol consumption prior to sexual activity. Nearly 35% of participants exhibited problematic drinking behaviour on the Alcohol Use Disorders Identification Test. Approximately 26% reported at least one incidence of binge drinking during the past year; 16% described having recently consumed alcohol before sexual activity. Risk factors included being older, being unmarried, having poorer mental health or increased number of traumatic events and socialising with family and friends two to four times a month. Attending religious services more than once a week appeared to protect against problematic drinking. Results emphasise the need for effective alcohol prevention campaigns in Angola and for targeting efforts towards individuals exhibiting the observed high-risk characteristics.

TI A single-scattering correction for the seismo-acoustic parabolic
equation
SO JOURNAL OF THE ACOUSTICAL SOCIETY OF AMERICA
LA English
DT Article
ID ELASTIC MEDIA; WAVE-PROPAGATION; OCEAN; INTERFACE; RAYLEIGH
AB An efficient single-scattering correction that does not require iterations is derived and tested for the seismo-acoustic parabolic equation. The approach is applicable to problems involving gradual range dependence in a waveguide with fluid and solid layers, including the key case of a sloping fluid-solid interface. The single-scattering correction is asymptotically equivalent to a special case of a single-scattering correction for problems that only have solid layers [Kusel , J. Acoust. Soc. Am. 121, 808-813 (2007)]. The single-scattering correction has a simple interpretation (conservation of interface conditions in an average sense) that facilitated its generalization to problems involving fluid layers. Promising results are obtained for problems in which the ocean bottom interface has a small slope. (C) 2012 Acoustical Society of America. [http://dx.doi.org/10.1121/1.3689557]

ID DUST MEASUREMENTS
AB The Al foils lining the aerogel tiles of the Stardust interstellar tray represent approximately 13% of the total collecting area, about 15,300 mm2. Although the flux is poorly constrained, fewer than 100 impacts are expected in all the Al foils on the collector, and most of these are likely to be less than 1 mu m in diameter. Secondary electron (SE) images of the foils at a resolution of approximately 50 nm per pixel are being collected during the Stardust Interstellar Preliminary Examination, resulting in more than two million images that will eventually need to be searched for impact craters. The unknown and complicated nature of 3-dimensional interstellar tracks in aerogel necessitated the use of a massively distributed human search to locate only a few interstellar tracks. The 2-dimensional nature of the SE images makes the problem of searching for craters tractable for algorithmic approaches. Using templates of craters from cometary impacts into Stardust foils, we present a computer algorithm for the identification of impact craters in the Stardust interstellar foils using normalized cross-correlation and template matching. We address the speed, sensitivity, and false-positive rate of the algorithm. The search algorithm can be adapted for use in other applications. The program is freely available for download at http://jake.ssl.berkeley. edu: 8000/groups/westphalgroup/wiki/14e52/ISPE_SEM_Crater_Search.html.

TI Aerodynamics of an aerofoil in transonic ground effect: numerical study
at full-scale Reynolds numbers
SO AERONAUTICAL JOURNAL
LA English
DT Article
ID AIRFOIL; FLOW
AB The potential positive effects of ground proximity on the aerodynamic performance of a wing or aerofoil have long been established, but at transonic speeds the formation of shock waves between the body and the ground plane would have significant consequences. A numerical study of the aerodynamics of an RAE2822 aerofoil section in ground effect flight was conducted as freestream Mach numbers from 0.5 to 0.9, at a range of ground clearances and angles of incidence. It was found that in general the aerofoil's lifting capability was still improved with decreasing ground clearance up until the point at which a lower surface shock wave formed (most commonly at the lowest clearances). The critical Mach number for the section was reached considerably earlier in ground effect than it would be in freestream, and the buffet boundary was therefore also reached at an earlier stage. The flowfields observed were relatively sensitive to changes in any given variable, and the lower surface shock had a destabilising effect on the pitching characteristics of the wing, indicating that sudden changes in both altitude and attitude would be experienced during sustained transonic flight close to the ground plane. Since ground proximity hastens the lower surface shock formation, no gain in aerodynamic efficiency can be gained by flying in ground effect once that shock is present.

TI EVIDENCE FOR TYPE Ia SUPERNOVA DIVERSITY FROM ULTRAVIOLET OBSERVATIONS

AB We present ultraviolet (UV) spectroscopy and photometry of four Type Ia supernovae (SNe 2004dt, 2004ef, 2005M, and 2005cf) obtained with the UV prism of the Advanced Camera for Surveys on the Hubble Space Telescope. This data set provides unique spectral time series down to 2000 angstrom. Significant diversity is seen in the near-maximum-light spectra (similar to 2000-3500 angstrom) for this small sample. The corresponding photometric data, together with archival data from Swift Ultraviolet/Optical Telescope observations, provide further evidence of increased dispersion in the UV emission with respect to the optical. The peak luminositiesmeasured in the uvw1/F250W filter are found to correlate with the B-band light-curve shape parameter Delta m(15)(B), but with much larger scatter relative to the correlation in the broadband B band (e.g., similar to 0.4 mag versus similar to 0.2 mag for those with 0.8 mag < Delta m(15)(B) < 1.7 mag). SN 2004dt is found as an outlier of this correlation (at > 3 sigma), being brighter than normal SNe Ia such as SN 2005cf by similar to 0.9 mag and similar to 2.0 mag in the uvw1/F250W and uvm2/F220W filters, respectively. We show that different progenitor metallicity or line-expansion velocities alone cannot explain such a large discrepancy. Viewing-angle effects, such as due to an asymmetric explosion, may have a significant influence on the flux emitted in the UV region. Detailed modeling is needed to disentangle and quantify the above effects.

AB Coronal pseudostreamers, which separate like-polarity coronal holes, do not have current sheet extensions, unlike the familiar helmet streamers that separate opposite-polarity holes. Both types of streamers taper into narrow plasma sheets that are maintained by continual interchange reconnection with the adjacent open magnetic field lines. White-light observations show that pseudostreamers do not emit plasma blobs; this important difference from helmet streamers is due to the convergence of like-polarity field lines above the X-point, which prevents the underlying loops from expanding outward and pinching off. The main component of the pseudostreamer wind has the form of steady outflow along the open field lines rooted just inside the boundaries of the adjacent coronal holes. These flux tubes are characterized by very rapid expansion below the X-point, followed by reconvergence at greater heights. Analysis of an idealized pseudostreamer configuration shows that, as the separation between the underlying holes increases, the X-point rises and the expansion factor f(ss) at the source surface increases. In situ observations of pseudostreamer crossings indicate wind speeds v ranging from similar to 350 to similar to 550 km s(-1), with O7+/O6+ ratios that are enhanced compared with those in high-speed streams but substantially lower than in the slow solar wind. Hydrodynamic energy-balance models show that the empirical v-f(ss) relation overestimates the wind speeds from nonmonotonically expanding flux tubes, particularly when the X-point is located at low heights and f(ss) is small. We conclude that pseudostreamers produce a "hybrid" type of outflow that is intermediate between classical slow and fast solar wind.

AB The relative permittivity, loss and dielectric strength have been measured for a polycarbonate-based material, tetraaryl bisphenol A polycarbonate, that has been fluorine substituted (DiF p-TABPA-PC). The new material has a glass transition temperature, T-g = 489 K, that is higher than that for either conventional bisphenol A polycarbonate (BPA-PC) for which T-g = 421 K or for a copolymer of tetraaryl bisphenol A (TABPA) and bisphenol A (BPA) (TABPA-BPA-PC) for which T-g = 464 K. In addition, the dielectric strength of DiF p-TABPA-PC is almost identical to that for purified BPA-PC and slightly larger than the value for TABPA-BPA-PC. The relative permittivity and loss measurements were carried out from 10 to 10(5) Hz over a wide temperature range and at pressures up to 0.25 GPa. Variable temperature results for the alpha relaxation and both temperature and pressure results for the gamma relaxation regions are reported. The alpha relaxation exhibits standard behavior. The gamma relaxation exhibits unusual characteristics such as a strong increase in peak height as temperature increases and a strong decrease in peak height with increasing pressure. The data for the gamma relaxation have been analyzed using several formulations. Expressions for the peak height and peak position based on a two state (inequivalent well) model and the resulting parameters are discussed in terms of the insight they provide into the molecular mechanisms responsible for the sub-T-g relaxation. Ab initio SCF results for a related model compound are presented. Finally, the real part of the relative permittivity for the new polymer is about 10% higher than for BPA-PC. (C) 2012 Elsevier Ltd.

AB This paper presents analysis of the effects of nonperiodic perturbations in periodic RF structures. Small departures from periodicity change the phase shift experienced by a wave as it traverses an imperfect cell. Cell imperfections may be introduced intentionally or due to fabrication errors or material properties variations. The cumulative effect produces distortions of the fields. If the errors are large enough, the structure modes become localized. This is the first demonstration of field localization in a periodic RF structure. Mechanisms, theory, and analytical relations describing the field distortion and localization phenomena are discussed. The results are demonstrated in periodic structures being investigated for submillimeter wave extended interaction klystrons. In an ancillary result, we discover a fundamental limitation of the finite element as well as other mesh-based codes when applied to long periodic structures.

AB We present a parallelization framework prototype for efficient physics-based computer simulation of hyperspectral time-dependent waveforms (i.e., wideband with a large number of frequency components) in nonlinear power amplifiers with memory. It relies on an adaptive algorithm for signal splitting and splicing in the time domain and uses a well-established pseudospectral multifrequency large-signal code, CHRISTINE, as its underlying simulation engine. Included in the model, and calculated from first-principles, are memory effects, such as dispersion and wave reflections. We validate our approach on a specific class of hyperspectral waveforms and study the effect of modifying a set of critical preprocessing parameters on the fidelity and the performance characteristics of the simulation.

ID BANDPASS-FILTERS; BANDSTOP FILTERS; TUNABLE FILTERS
AB Intrinsically switched tunable filters are switched on and off using the tuning elements that tune their center frequencies and/or bandwidths, without requiring an increase in the tuning range of the tuning elements. Because external RF switches are not needed, substantial improvements in insertion loss, linearity, dc power consumption, control complexity, size, and weight are possible compared to conventional approaches. An intrinsically switched varactor-tuned bandstop filter and bandpass filter bank are demonstrated here for the first time. The intrinsically switched bandstop filter prototype has a second-order notch response with more than 50 dB of rejection continuously tunable from 665 to 1000 MHz (50%) with negligible passband ripple in the intrinsic off state. The intrinsically switched tunable bandpass filter bank prototype, comprised of three third-order bandpass filters, has a constant 50-MHz bandwidth response continuously tunable from 740 to 1644MHz (122%) with less than 5 dB of passband insertion loss and more than 40 dB of isolation between bands.

DT Article
DE multichannel array processing; SRP-PHAT; sound source localization (SSL)
ID LOCATION; SPEECH; SYSTEM
AB This paper describes a method for estimating Direction Of Arrival (DOA) of multiple sound sources in full azimuth with three microphones. Estimating DOA with paired microphone arrays creates imaginary sound sources because of time delay of arrival (TDOA) being identical between real and imaginary sources. Imaginary sound sources can create chronic problems in multiple Sound Source Localization (SSL), because they can be localized as real sound sources. Our proposed approach is based on the observation that each microphone array creates imaginary sound sources, but the DOA of imaginary sources may be different depending on the orientation of the paired microphone array. With the fact that a real source would always be localized in the same direction regardless of the array orientation, we can suppress the imaginary sound sources by minimum filtering based on Steered Response Power-Phase Transform (SRP-PHAT) method. A set of experiments conducted in a real noisy environment showed that the proposed method was accurate in localizing multiple sound sources.

ID COASTAL-TRAPPED WAVES; SEA-LEVEL; ISLAND
AB The authors address the propagation of continental shelf waves in the Mid-Atlantic Bight. An analytical model of the bathymetry in the region is constructed by representing the continental shelf as a gently sloping bottom, which deepens linearly with offshore distance to the place where it meets the continental slope. Seaward of that point, the bathymetry is modeled with an exponentially decaying function of distance. The linearized, barotropic equations of hydrostatic motion, subject to the long-wave approximation, yield separate shelf and slope solutions, which are matched at the shelf break to specify the eigenfunctions. The associated eigenvalues define the dispersion relations for each of the modes. Wavenumber frequency pairs derived from NOAA sea surface height stations along the coast are plotted on the first-mode dispersion curve, and the agreement is good. The theory also shows good agreement with the wave data of D. P. Wang.

AB Monobromoindigo is a component of Tyrian purple, a purplered natural colorant extracted from various species of sea snails, which was possibly first produced by the ancient Phoenicians and has been employed as a symbol of royalty and power by several civilizations over the centuries. Raman spectroscopy has proved to be an effective analytical technique to detect historical dyes, as it allows rapid and accurate identification of unknowns in a nondestructive way. Although other constituents of Tyrian purple have been comprehensively investigated by Raman spectroscopy, the Raman bands of 6-bromoindigo, a molecule that has been correlated with a specific snail species, Hexaplex trunculus (also known as Murex trunculus), have been reported but not previously assigned. This paper includes a complete assignment of the Raman spectrum of the 6-bromoindigo isomer, including experimental spectra recorded at 488 and 785?nm, which were compared with those collected from indigo under the same conditions. Theoretical Raman spectra for both molecules were obtained using density functional theory calculations. Copyright (c) 2011 John Wiley & Sons, Ltd.

AB Objective: To determine the rate at which long-acting reversible contraception (LARC) is desired immediately postpartum and utilized within 12 weeks of delivery at our institution.
Methods: This prospective cohort study analyzed 400 consecutive postpartum patients between January 2009 and March 2009. We followed contraceptive desire prior to discharge and actual contraception utilized within 12 weeks postpartum. Patient demographics and LARC utilization was analyzed to determine characteristics predictive of use.
Results: There was complete follow-up information on 329 (82.3%) of the studied women. Thirty-three percent (132/400) desired LARC immediately postpartum, and overall LARC utilization at 12 weeks was 31% (100/329). Demographic characteristics predictive of LARC desire and utilization included age <25 years (adjusted RR = 1.53, 95% CI 1.17-1.92) and African-American ethnicity (adjusted RR = 1.39, 95% CI 1.03-1.78).
Conclusion: In our institution, LARC is highly desired and utilized within 12 weeks postpartum with African-American ethnicity and age <25 years predictive of use.

AB A combined tropical cyclone dynamic initialization three-dimensional variational data assimilation scheme (TCDI-3DVAR) is proposed. The specific procedure for the new initialization scheme is described as follows. First, a first-guess vortex field derived from a global analysis will be spun up in a full-physics mesoscale regional model in a quiescent environment. During the spinup period, the weak vortex is forced toward the observed central minimum sea level pressure (MSLP). The so-generated balanced TC vortex with realistic MSLP and a warm core is then merged into the environmental field and used in the subsequent 3DVAR data assimilation. The observation system simulation experiments (OSSEs) demonstrate that this new TC initialization scheme leads to much improved initial MSLP, warm core, and asymmetric temperature patterns compared to those from the conventional 3DVAR scheme. Forecasts of TC intensity with the new initialization scheme are made, and the results show that the new scheme is able to predict the "observed" TC intensity change, compared to runs with the conventional 3DVAR scheme or the TCDI-only scheme. Sensitivity experiments further show that the intensity forecasts with knowledge of the initial MSLP and wind fields appear more skillful than do the cases where the initial MSLP, temperature, and humidity fields are known. The numerical experiments above demonstrate the potential usefulness of the proposed new initialization scheme in operational applications. A preliminary test of this scheme with a navy operational model shows encouraging results.

AB Studies of molecular hot cores and protostellar environments have shown that the observed abundance of gas-phase acetylene (C2H2) cannot be matched by chemical models without the inclusion of C2H2 molecules subliming from icy grain mantles. Searches for infrared (IR) spectral features of solid-phase acetylene are under way, but few laboratory reference spectra of C2H2 in icy mixtures, which are needed for spectral fits to observational data, have been published. Here, we report a systematic study of the IR spectra of condensed-phase pure acetylene and acetylene in ices dominated by carbon monoxide (CO), carbon dioxide (CO2), methane (CH4), and water (H2O). We present new spectral data for these ices, including band positions and intrinsic band strengths. For each ice mixture and concentration, we also explore the dependence of acetylene's nu(5)-band position (743 cm(-1), 13.46 mu m) and FWHM on temperature. Our results show that the nu(5) feature is much more cleanly resolved in ices dominated by non-polar and low-polarity molecules, specifically CO, CO2, and CH4, than in mixtures dominated by H2O-ice. We compare our laboratory ice spectra with observations of a quiescent region in Serpens.

AB In this paper, we present a number of approaches using fuzzy set theory to influence decision-making behavior, which is a type of human persuasion. We couch the approach as the process to draw a conclusion "V is P" given "V is F," where P is a fuzzy subset of F representing some linguistic value for V that corresponds to a perception of the world V is P, which we want a person to accept. We examine several methods to represent the process to engender such influences. These include using a person's predispositions, framing the context of a discussion and generalization techniques that allow issues to be viewed in a more favorable light. Finally, we discuss approaches to the related topic of negotiations. This paper describes these approaches and the required background formalisms that are used in them.

AB Military personnel deployed in support of combat operations are at significantly higher risk for mental health problems. However, much of what we know about combat-related mental health comes from postdeployment assessments. This study describes the mental health of 1,336 treatment-seeking deployed U.S. military personnel and interventions recommended by military mental health providers in Iraq from January 2006 to January 2007. Cases were primarily young enlisted men, most of whom were on their first combat deployment. Marines made up the majority of the cases (60%), but there were also large numbers of Army and Navy personnel. The most common psychiatric diagnoses were anxiety disorders (31%, including 11% with posttraumatic stress disorder), followed by adjustment (27%) and mood disorders (25%, including 22% with depression). Medication was the most commonly prescribed treatment for patients with psychiatric diagnoses but was often combined with recommendations for psychotherapy/counseling and/or behavioral modifications. The findings illustrate the distribution of mental health conditions seen among treatment-seeking troops while actively serving in a combat environment and the interventions recommended for them. Further examination of postdeployment health outcomes may help to facilitate the development of more effective acute intervention strategies in theater.

AB While awaiting rescue from a disabled submarine (DISSUB), survivors will likely endure an atmosphere of rising CO2 which will eventually be lethal. Previously, it was determined that low-close propranolol reduces resting metabolic carbon dioxide production and therefore may increase survival time in this scenario. The actions and decisions survivors would carry out in a DISSUB situation would require an unaltered cognition state. Therefore, we wanted to determine if low-dose propranolol impairs cognitive function. Eight healthy males completed a counterbalanced, randomized, placebo-controlled, double-blinded crossover study in which each subject received propranolol (40 mg twice daily) or placebo (lactose pill twice daily) over a 72-hour period. The alternate condition was separated by a minimum 96-hour washout period. Subjects performed a series of 6 tasks from the Automated Neuropsychological Assessment Metrics (ANAM) battery and answered a self-report sleepiness scale each morning and afternoon. Subjects exhibited increased accuracy in one of the ANAM tasks while on propranolol compared to placebo, but showed no difference between treatments on the other 5 tasks and sleepiness scale. These results suggest that 40 mg of propranolol taken twice daily does not significantly impair cognitive function and may be a viable option for use in a DISSUB scenario.

AB Spontaneous pneumothorax is a commonly encountered problem in the Emergency Department. Patients are often treated without further investigation for an underlying etiology. We present a patient who was unable to completely resolve a pneumothorax and was found to have lymphangioleiomyomatosis (LAM), a rare cystic lung disease. In the past. LAM was difficult to diagnose and had a mortality of 100% after 10 years, but now there is a 71% survival after 10 years. Recent research has led to increased characterization of the pathology and radiographic findings. This article briefly presents the case and discusses the etiology, diagnosis, and treatment of LAM.

AB This study investigates the characteristic differences of tropical disturbances that eventually develop into tropical cyclones (TCs) versus those that did not, using global daily analysis fields of the Navy Operational Global Atmospheric Prediction System (NOGAPS) from the years 2003 to 2008. Time filtering is applied to the data to extract tropical waves with different frequencies. Waves with a 3-8-day period represent the synoptic-scale disturbances that are representatives as precursors of TCs, and waves with periods greater than 20 days represent the large-scale background environmental flow. Composites are made for the developing and nondeveloping synoptic-scale disturbances in a Lagrangian frame following the disturbances. Similarities and differences between them are analyzed to understand the dynamics and thermodynamics of TC genesis. Part I of this study focuses on events in the North Atlantic, while Part II focuses on the western North Pacific. A box difference index (BDI), accounting for both the mean and variability of the individual sample, is introduced to subjectively and quantitatively identify controlling parameters measuring the differences between developing and nondeveloping disturbances. Larger amplitude of the BDI implies a greater possibility to differentiate the difference between two groups. Based on their BDI values, the following parameters are identified as the best predictors for cyclogenesis in the North Atlantic, in the order of importance: 1) water vapor content within 925 and 400 hPa, 2) rain rate, 3) sea surface temperature (SST), 4) 700-hPa maximum relative vorticity, 5) 1000-600-hPa vertical shear, 6) translational speed, and 7) vertically averaged horizontal shear. This list identifies thermodynamic variables as more important controlling parameters than dynamic variables for TC genesis in the North Atlantic. When the east and west (separated by 40 degrees W) Atlantic are examined separately, the 925-400-hPa water vapor content remains as the most important parameter for both regions. The SST and maximum vorticity at 700 hPa have higher importance in the east Atlantic, while SST becomes less important and the vertically averaged horizontal shear and horizontal divergence become more important in the west Atlantic.

AB Global daily reanalysis fields from the Navy Operational Global Atmospheric Prediction System (NOGAPS) are used to analyze Northern Hemisphere summertime (June-September) developing and nondeveloping disturbances for tropical cyclone (TC) formation from 2003 to 2008. This is Part II of the study focusing on the western North Pacific (WNP), following Part I for the North Atlantic (NATL) basin. Tropical cyclone genesis in the WNP shows different characteristics from that in the NATL in both large-scale environmental conditions and prestorm disturbances.
A box difference index (BDI) is used to identify parameters in differentiating between the developing and nondeveloping disturbances. In order of importance, they are 1) 800-hPa maximum relative vorticity, 2) rain rate, 3) vertically averaged horizontal shear, 4) vertically averaged divergence, 5) 925-400-hPa water vapor content, 6) SST, and 7) translational speed. The study indicates that dynamic variables are more important in TC genesis in the WNP, while in Part I of the study the thermodynamic variables are identified as more important in the NATL. The characteristic differences between the WNP and the NATL are compared.

AB An analysis of three predecessor rain events (PREs) that occurred ahead of North Atlantic tropical cyclone (TC) Ike and east Pacific TC Lowell during 10-15 September 2008 is presented. The three PREs produced all-time daily record rainfall at many locations, including Lubbock, Texas (189.5 mm); Wichita, Kansas (262 mm); and Chicago-O'Hare, Illinois (169 mm), on 11-13 September, respectively. PRE 1 organized over Texas on 10 September with moisture from a stalled frontal boundary and the Bay of Campeche, and matured with moisture from TC Lowell. PRE 2 organized over the Texas Panhandle on 11 September with moisture from the Bay of Campeche, and developed and matured over Kansas and Missouri with moisture from TC Lowell. PRE 3 developed over Texas on 11 September, merged with and absorbed PRE 2 over Kansas and Missouri, and matured as it ingested moisture from TC Ike All three PREs matured in the equatorward entrance region of an intensifying subtropical jet stream (STJ).
Heavy rainfall with the three PREs occurred along a plume of moist air characterized by high precipitable water values that extended poleward over the central United States near the juxtaposition of the nose of a low-level jet, a region of lower-tropospheric forcing for ascent along a surface baroclinic zone, and the STJ equatorward entrance region. The cumulative upscale effect of persistent deep convection from the three PREs enhanced and "locked in" a favorable upper-tropospheric flow pattern conducive to ridge development over the Ohio Valley and STJ intensification over the central U.S. and Great Lakes region.

AB In support of the National Science Foundation Pre-Depression Investigation of Cloud-systems in the tropics (NSF PREDICT) and National Aeronautics and Space Administration Genesis and Rapid Intensification Processes (NASA GRIP) dry run exercises and National Oceanic and Atmospheric Administration Hurricane Intensity Forecast Experiment (NOAA IFEX) during the 2009 hurricane season, a real-time wave-tracking algorithm and corresponding diagnostic analyses based on a recently proposed tropical cyclogenesis model were applied to tropical easterly waves over the Atlantic. The model emphasizes the importance of a Lagrangian recirculation region within a tropical-wave critical layer (the so-called pouch), where persistent deep convection and vorticity aggregation as well as column moistening are favored for tropical cyclogenesis. Distinct scenarios of hybrid wave-vortex evolution are highlighted. It was found that easterly waves without a pouch or with a shallow pouch did not develop. Although not all waves with a deep pouch developed into a tropical storm, a deep wave pouch had formed prior to genesis for all 16 named storms originating from monochromatic easterly waves during the 2008 and 2009 seasons. On the other hand, the diagnosis of two nondeveloping waves with a deep pouch suggests that strong vertical shear or dry air intrusion at the middle-upper levels (where a wave pouch was absent) can disrupt deep convection and suppress storm development.
To sum up, this study suggests that a deep wave pouch extending from the midtroposphere (similar to 600-700 hPa) down to the boundary layer is a necessary condition for tropical cyclone formation within an easterly wave. It is hypothesized also that a deep wave pouch together with other large-scale favorable conditions provides a sufficient condition for sustained convection and tropical cyclone formation. This hypothesized sufficient condition requires further testing and will be pursued in future work.

AB We demonstrate the first successful growth of large-area (200 X 200 mu m(2)) bilayer, Bernal stacked, epitaxial graphene (EG) on atomically flat, 4H-SiC (0001) step-free mesas (SFMs). The use of SFMs for the growth of graphene resulted in the complete elimination of surface step-bunching typically found after EG growth on conventional nominally on-axis SiC (0001) substrates. As a result heights of EG surface features are reduced by at least a factor of SO from the heights found on conventional substrates. Evaluation of the EG across the SFM using the Raman 2D mode indicates Bernal stacking with low and uniform compressive lattice strain of only 0.05%. The uniformity of this strain is significantly improved, which is about 13-fold decrease of strain found for EG grown on conventional nominally on-axis substrates. The magnitude of the strain approaches values for stress-free exfoliated graphene flakes. Hall transport measurements on large area bilayer samples taken as a function of temperature from 4.3 to 300 K revealed an n-type carrier mobility that increased from 1170 to 1730 cm(2) V-1 s(-1), and a corresponding sheet carrier density that decreased from 5.0 X 10(12) cm(-2) to 3.26 X 10(12) cm(-2). The transport is believed to occur predominantly through the top EG layer with the bottom layer screening the top layer from the substrate. These results demonstrate that EG synthesized on large area, perfectly flat on-axis mesa surfaces can be used to produce Bernal-stacked bilayer EG having excellent uniformity and reduced strain and provides the perfect opportunity for significant advancement of epitaxial graphene electronics technology.

AB This report entails in vivo and in vitro studies concerned with free radical species involved in brain ischemia. The participation of reactive oxygen species (ROS) and reactive nitrogen species (RNS) in the early manifestation of cerebral ischemia/reperfusion was investigated in gerbils exposed to transient global ischemia using 4-OH-2,2,6,6-Tetramethylpiperidine-1-oxyl (TPL), a well-known antioxidant. TPL treatment reversed cerebral postischemic hypoperfusion and tissue edema in these animals. The findings are consistent with ROS/RNS participation in tissue injury and the reduction of cerebromicrovascular blood flow (CBF) during postischemic recirculation. The activation/deactivation of signal transduction pathway by oxidation/antioxidation [i.e., using hydrogen peroxide (H2O2)/TPL] was evaluated in cultured human brain endothelial cells (HBEC) to assess the involvement of endothelial-dependent mechanisms. The data showed that H2O2 activates various "stress" kinases and vasodilalator-stimulated phosphoprotein (VASP); activation of this pathway was reduced by inhibitors of Rho-or IP-3 kinases, as well as TPL. H2O2 also induced cytoskeleton (actin) rearrangements in HBEC; this effect was prevented by inhibitors of Rho/IP3 kinase or TPL. The observed activation/deactivation of H2O2-induced "stress" kinase is in agreement with the reported capacity of ROS/RNS to stimulate the oxidative signal transduction pathway. The noted TPL reduction of H2O2-induced phosphorylation of kinase strongly suggests that the beneficial effect of TPL implicates the stress signal transduction pathway. This may represent a mechanism for the cerebral postischemic manifestations observed by in vivo experiments.

AB A regional climate model is used to simulate the summer monsoon onset in South and Southeast Asia during the year 2000 to explore the interaction between orographic precipitation and the large-scale monsoon circulation. In the control run, the model uses the U. S. Geological Survey topography data and simulates the observed monsoon onset reasonably well. In the sensitivity tests, mountains are removed within different regions south of the Tibetan Plateau. It is found that the Indochina Peninsula monsoon onset is closely related to the local wind-terrain-precipitation interaction, while the Indian monsoon onset is more controlled by the large-scale land-sea thermal contrast.
The sensitivity tests suggest two opposite effects of high terrain on the monsoon circulation and precipitation. When the terrain height is below the lifted condensation level (LCL), the low-level westerlies and the orographic precipitation weaken with increasing terrain height due to the surface drag effect. When the terrain height is above the LCL, the positive feedback associated with the diabatic forcing of orographic precipitation is dominant, and a large mountain height leads to heavier orographic precipitation and stronger low-level westerlies. The sensitivity tests also show that the impact of orographic precipitation in the Indochina Peninsula extends up to 30 degrees longitude upstream and affects monsoon precipitation along the western coast of India.

ID IRRADIANCE; CLIMATE
AB Recent observations made by the Spectral Irradiance Monitor (SIM) on the Solar Radiation and Climate Experiment (SORCE) spacecraft suggest that the Sun's visible and infrared spectral irradiance increased from 2004 to 2008, even as the total solar irradiance measured simultaneously by SORCE's Total Irradiance Monitor (TIM) decreased. At the same time, solar ultraviolet (UV) irradiance decreased 3-10 times more than expected from prior observations and model calculations of the known effects of sunspot and facular solar features. Analysis of the SIM spectral irradiance observations during the solar minimum epoch of 2008, when solar activity was essentially invariant, exposes trends in the SIM observations relative to both total solar irradiance and solar activity that are unlikely to be solar in origin. The authors suggest that the SIM's radically different solar variability characterization is a consequence of undetected instrument sensitivity drifts, not true solar spectrum changes. It is thus doubtful that simulations of climate and atmospheric change using SIM measurements are indicative of real terrestrial behavior.

ID SURGICAL ANATOMY; FRACTURES; PALSY; SHAFT
AB Objective: Identification of the radial nerve is necessary during the posterior approach to the humerus in an effort to maintain its integrity. Other than anatomic descriptions of the radial nerve with respect to osseous structures, there are few superficial intraoperative landmarks along the course of the traditional triceps-splitting approach to provide facile nerve identification. The objective of this study was to determine the reliability of using the anatomic intersection of the long and lateral heads of the triceps and the triceps aponeurosis as a superficial reference point for radial nerve identification during the posterior approach to the humerus.
Methods: Thirty adult human cadaver upper extremities as 15 matched pairs were used. Systematic identification and measurement from the point of intersection between the long and lateral heads of the triceps and the triceps aponeurosis to the distal most aspect of the radial nerve as it coursed the posterior humerus at its midaxial point was performed and recorded.
Results: Mean distance was found to measure 39.0 +/- 2.1 mm (range, 36-44 mm), approximating a fixed distance, two finger breadths proximal to our identified point of intersection. Statistical analysis between the two matched pair groups yielded no significant difference in measured distances (P = 0.88).
Conclusions: Our group has identified the point of intersection among three landmarks forming a point of intersection. This point is the confluence of the long and lateral heads of the triceps and the triceps aponeurosis. This serves as a visualized anatomic reference point during the posterior surgical exposure to the humerus and can be used to identify the radial nerve as it courses the posterior humerus.

AB Preclinical studies suggest that GP2, a HER2/neu-derived peptide, is immunogenic. Subsequent phase I clinical trials demonstrated that GP2-based vaccines are safe and effective in stimulating peptide-specific immunity. A GP2 peptide vaccine is currently being evaluated in a phase II efficacy trial enrolling breast cancer patients. This article reviews initial studies characterizing GP2, clinical trials investigating GP2-based vaccines, and novel immunotherapy strategies incorporating GP2 in combination with other peptides or with the monoclonal antibody trastuzumab.

AB The Hill-Sachs lesion is an osseous defect of the humeral head that is typically associated with anterior shoulder instability. The incidence of these lesions in the setting of glenohumeral instability is relatively high and approaches 100% in persons with recurrent anterior shoulder instability. Reverse Hill-Sachs lesion has been described in patients with posterior shoulder instability. Glenoid bone loss is typically associated with the Hill-Sachs lesion in patients with recurrent anterior shoulder instability. The lesion is a bipolar injury, and identification of concomitant glenoid bone loss is essential to optimize clinical outcome. Other pathology (eg, Bankart tear, labral or capsular injuries) must be identified, as well. Treatment is dictated by subjective and objective findings of shoulder instability and radiographic findings. Nonsurgical management, including focused rehabilitation, is acceptable in cases of small bony defects and nonengaging lesions in which the glenohumeral joint remains stable during desired activities. Surgical options include arthroscopic and open techniques.

AB This study examines further the characteristics of turbulent flow in the low-level region of intense hurricanes using in situ aircraft observations. The data analyzed here are the flight-level data collected by research aircraft that penetrated the eyewalls of category-5 Hurricane Hugo (1989), category-4 Hurricane Allen (1980), and category-5 Hurricane David (1979) between 1 km and the sea surface. Estimates of horizontal eddy momentum flux, horizontal eddy diffusivity, and horizontal mixing length are obtained. It is found that the horizontal momentum flux and horizontal diffusivity increase with increasing wind speed. The horizontal mixing length increases slightly with wind speed also, but the mixing length is not significantly dependent on the wind speed. The magnitude of the horizontal momentum flux is found to be comparable to that of the vertical momentum flux, indicating that horizontal mixing by turbulence becomes nonnegligible in the hurricane boundary layer, especially in the eyewall region.
Within the context of simple K theory, the results suggest that the average horizontal eddy diffusivity and mixing length are approximately 1500 m(2) s(-1) and 750 m, respectively, at about 500 m in the eyewall region corresponding to the mean wind speed of approximately 52 m s(-1). It is recalled also that the mixing length is a virtual scale in numerical models and is quantitatively smaller than the energy-containing scale of turbulent eddies. The distinction between these two scales is a useful reminder for the modeling community on the representation of small-scale turbulence in hurricanes.

AB We report the results of a low frequency radio variability and slow transient search using archival observations from the Very Long Array. We selected six 325 MHz radio observations from the spring of 2006, each centered on the Spitzer-Space-Telescope Wide-area Infrared Extragalactic Survey (SWIRE) Deep Field: 1046+59. Observations were spaced between one day to three months, with a typical single-epoch peak flux sensitivity below 0.2 mJy beam(-1) near the field pointing center. We describe the observation parameters, data post-processing, and search methodology used to identify variable and transient emission. Our search revealed multiple variable sources and the presence of one, day-scale transient event with no apparent astronomical counterpart. This detection implies a transient rate of 1 +/- 1 event per 6.5 deg(2) per 72 observing hours in the direction of 1046+59 and an isotropic transient surface density Sigma = 0.12 deg(-2) at 95% confidence for sources with average peak flux density higher than 2.1 mJy over 12 hr.

AB Background: Nephrolithiasis is a common medical condition among aviation personnel that can negatively impact their health and careers. Due to the potentially severe consequences of in-flight renal colic associated with nephrolithiasis, current Navy regulations stipulate extensive evaluation for any aircrew member who has an instance of kidney stones. Case Report: Two cases of Naval aircrew members with kidney stones are reviewed and current Navy standards regarding nephrolithiasis are discussed. Discussion: Current Navy standards for granting aeromedical waivers for kidney stones do not differentiate between pilots in actual control of the aircraft and other aircrew members among aircraft personnel. Furthermore, a premium is placed on stone-free status, even for asymptomatic, incidentally found nephroliths. This policy has many similarities, but also significant differences from those of other services and those of civilian aviation authorities. This difference in protocols across aviation communities should be re-examined in order to promote more efficient return to flying duties of operational personnel without compromising safety of flight.

AB Cytochrome c oxidase is an efficient energy transducer that reduces oxygen to water and converts the released chemical energy into an electrochemical membrane potential. As a true proton pump, cytochrome c oxidase translocates protons across the membrane against this potential. Based on a wealth of experiments and calculations, an increasingly detailed picture of the reaction intermediates in the redox cycle has emerged. However, the fundamental mechanism of proton pumping coupled to redox chemistry remains largely unresolved. Here we examine and extend a kinetic master-equation approach to gain insight into redox-coupled proton pumping in cytochrome c oxidase. Basic principles of the cytochrome c oxidase proton pump emerge from an analysis of the simplest kinetic models that retain essential elements of the experimentally determined structure, energetics, and kinetics, and that satisfy fundamental physical principles. The master-equation models allow us to address the question of how pumping can be achieved in a system in which all reaction steps are reversible. Whereas proton pumping does not require the direct modulation of microscopic reaction barriers, such kinetic gating greatly increases the pumping efficiency. Further efficiency gains can be achieved by partially decoupling the proton uptake pathway from the active-site region. Such a mechanism is consistent with the proposed Glu valve, in which the side chain of a key glutamic acid shuttles between the D channel and the active-site region. We also show that the models predict only small proton leaks even in the absence of turnover. The design principles identified here for cytochrome c oxidase provide a blueprint for novel biology-inspired fuel cells, and the master-equation formulation should prove useful also for other molecular machines.

AB Immunoglobulin (Ig)G levels are important for antibody vaccine responses and IgG subclass deficiencies have been associated with severe 2009 influenza A (H1N1) infections. Studies have demonstrated variations in immune responses to the H1N1 vaccine, but the aetiology of this is unknown. We determined the associations between pre-vaccination overall and influenza-specific IgG subclass levels and 2009 H1N1-specific antibody responses post-vaccination (robust versus poor at day 28) stratified by human immunodeficiency virus (HIV) status. Logistic regression models were utilized to evaluate whether pre-vaccination IgG subclass levels were associated with the antibody response generated post-vaccination. We evaluated 48 participants as part of a clinical study who were stratified by robust versus poor post-vaccination immune responses. Participants had a median age of 35 years; 92% were male and 44% were Caucasian. HIV-infected adults had a median CD4 count of 669 cells/mm3, and 79% were receiving highly active anti-retroviral therapy. HIV-infected participants were more likely to have IgG2 deficiency (<240 mg/dl) than HIV-uninfected individuals (62% versus 4%, P < 0.001). No association of pre-vaccination IgG subclass levels (total or influenza-specific) and the antibody response generated by HIN1 vaccination in either group was found. In summary, pre-vaccination IgG subclass levels did not correlate with the ability to develop robust antibody responses to the 2009 influenza A (H1N1) monovalent vaccine. IgG2 deficiencies were common among HIV-infected individuals but did not correlate with poor influenza vaccine responses. Further investigations into the aetiology of disparate vaccine responses are needed.

AB Despite that underwater acoustic channels are well known to contain various interferences, research on interference mitigation in underwater acoustic communications has been very limited. In this paper, we deal with a wideband orthogonal frequency division multiplexing (OFDM) transmission in the presence of an external interference which occupies partially the signal band and whose time duration is shorter than the OFDM block. We parameterize the unknown interference waveform by a number of parameters assuming prior knowledge of the frequency band and time duration of the interference, and develop an iterative receiver, which couples interference detection via a generalized likelihood-ratio-test (GLRT), interference reconstruction and cancellation, channel estimation, and data detection. In addition to simulation results, we verify the receiver performance using data sets collected from two experiments. In both time-invariant and time-varying channels, the proposed iterative receiver achieves robust performance in the presence of unknown interference.

AB In this article, case-study inverse thermal analyses of Al2198 laser welds are presented. These analyses employ a numerical methodology, that is, in terms of analytic and numerical basis functions for inverse thermal analysis of steady-state energy deposition in plate structures. The results of the case studies presented provide parametric representations of weld temperature histories that can be adopted as input data to various types of computational procedures, such as those for prediction of solid-state phase transformations and their associated software implementations. In addition, these weld temperature histories can be used for construction of numerical basis functions that can be adopted for inverse analysis of welds corresponding to other process parameters or welding processes whose process conditions are within similar regimes.

AB This paper presents an intelligent controller for underwater vehicle-manipulator systems (UVMS) based on the neuro-fuzzy approach. The controller is composed of fuzzy PD control with membership function tuning by linguistic hedge. A neural network compensator approximates the dynamics of the UVMS in decentralized form. The new controller has the advantages of simplicity of implementation due to decentralized design, precision, and robustness to payload variations and hydrodynamic disturbances. It has significantly low energy consumption compared to both the conventional PD and conventional fuzzy control methods. The effectiveness of the proposed controller is illustrated by results of simulations for a six degrees of freedom autonomous underwater vehicle with a three degrees of freedom on-board manipulator.

AB Stress fractures commonly plague runners; the repetitive, continuous, and or excessive forces placed on the bone lead to bony microdamage and progress to stress fractures. Stress fractures are classified as high or low risk; High-risk fractures draw special recognition because of their risk for nonunion and for the significant complications associated with fracture completion. Surgical fixation for a high-risk stress fracture is often indicated, where low-risk fractures can be treated conservatively. Proven measures to prevent stress fractures include cushioned running shoes, interval training, and calcium supplementation.

AB The truncation of large physical domains to concentrate computational resources is necessary or desirable in simulating many natural and man-made plasma phenomena. Three open boundary condition (BC) methods for such domain truncation of dissipative magnetohydrodynamics (MHD) problems are described and compared here. A novel technique, lacuna-based open boundary conditions (LOBC), is presented for applying open BC to dissipative MHD and other hyperbolic and mixed hyperbolic-parabolic systems of partial differential equations. LOBC, based on manipulating Calderon-type near-boundary sources, essentially damp hyperbolic effects in an exterior region attached to the simulation domain and apply BC appropriate for the remaining parabolic effects (if present) at the exterior region boundary. Another technique, approximate Riemann BC (ARBC), is adapted from finite volume and discontinuous Galerkin methods. In ARBC, the value of incoming flux is specified using a local, characteristic-based method. A third commonly-used open BC, zero-normal derivative BC (ZND BC), is presented for comparison. These open BC are tested in several gas dynamics and dissipative MHD problems. LOBC are found to give stable, low-reflection solutions even in the presence of strong parabolic behavior, while ARBC are stable only when hyperbolic behavior is dominant. Pros and cons of the techniques are discussed and put into context within the body of open BC research to date. (C) 2012 Elsevier Inc. All rights reserved.

AB A prototype shipboard filter skid (p1SFS) was designed and built to facilitate shipboard collection and concentration of epsilon 50 m planktonic organisms from large volumes of water. The p1SFS consisted of two stainless steel filter housings, each containing a filter bag, arranged in parallel. Validation of the device examined the particle retention efficiency of filter bags (using inert polystyrene microbeads), the potential toxicity of filter skid materials and the capture efficiency of plankton collected with a filter skid versus a plankton net at two sample volumes (5 and 10 m(3)). Microbead recovery in filter bags was 89 and 100 for microbeads of 50 and 150 m diameters, respectively. Exposure to the sealant used to close the filter bags seams or stainless steel did not lead to mortality of two model zooplankton species. Overall, the concentration of epsilon 50 m plankton in the p1SFS relative to concentrations in the plankton net (i.e. the capture efficiency, CE) was 108 66 (mean 1 SD, n 6). The p1SFS CE was higher in experiments with 5 m(3) sample volume (147 74; n 3) relative to experiments with a 10 m(3) sample volume (69 28, n 3), although the difference in CE between the sample volumes was not significant. Consequently, these experiments suggest this or similarly validated filter skids are appropriate for in-line sampling of plankton from relatively large volumes of water.

AB Large, deep, well shielded liquid detectors have become an important technology for the detection of neutrinos over a wide dynamic range from few MeV to TeV. The critical component of this technology is the large format semi-hemispherical photo-multiplier tube with diameters in the range of 25-50 cm. The survival of an assembled array of these photo-multiplier tubes under high hydrostatic pressure is the subject of this study. These are the results from an R&D program which is intended to understand the modes of failure when a photo-multiplier tube implodes under hydrostatic pressure. Our tests include detailed measurements of the shock wave which results from the implosion of a photo-multiplier tube and a comparison of the test data to modern hydrodynamic simulation codes. Using these results we can extrapolate to other tube geometries and make recommendation on deployment of the photo-multiplier tubes in deep water detectors with a focus on risk mitigation from a tube implosion shock wave causing a chain reaction loss of multiple tubes.

ID SOLAR-CELLS; EFFICIENCY; RADIATION
AB The balance of photogeneration and recombination gives rise to an optimum bandgap for any solar cell. The radiative limit represents the lowest permissible level of recombination in a solar cell and, therefore, places an upper limit on the voltage that can be attained. Introducing additional nonradiative recombination results in a loss in voltage that can only be compensated for by moving to higher bandgaps. Consequently, the optimal bandgap for solar energy conversion will rise with increasing nonradiative recombination rate. This balance was recognized by Shockley and Queisser for single-junction solar cells and is here extended to multijunction solar cells. A rise in optimal bandgaps has been observed in simulated single-, double-, and triple-junction devices as nonradiative recombination increases. Optimal bandgaps between excellent and poor diode quality devices are shown to differ by 100s of meV under 1-sun illumination with both terrestrial and extraterrestrial spectra but exhibit no significant change at high concentration due to the dominance of the radiative component in the recombination dynamics.

AB We describe a methodology for optimizing a threshold detection-based biosurveillance system. The goal is to maximize the system-wide probability of detecting an "event of interest" against a noisy background, subject to a constraint on the expected number of false signals. We use nonlinear programming to appropriately set detection thresholds taking into account the probability of an event of interest occurring somewhere in the coverage area. Using this approach, public health officials can "tune" their biosurveillance systems to optimally detect various threats, thereby allowing practitioners to focus their public health surveillance activities. Given some distributional assumptions, we derive a one-dimensional optimization methodology that allows for the efficient optimization of very large systems. We demonstrate that optimizing a syndromic surveillance system can improve its performance by 20-40%. Published by Elsevier B.V.

AB This study examined the 1979-2004 volume and freshwater fluxes through the Canadian Arctic Archipelago (CAA) and into the Labrador Sea using a high resolution (similar to 9 km) coupled ice-ocean model of the pan-Arctic region to provide a reference, compare with limited observational estimates, and investigate control mechanisms of this exchange. The 26-year mean volume and freshwater fluxes through Nares Strait were 0.77 Sv +/- 0.17 Sv and 10.38 mSv +/- 1.67 mSv respectively, while those through Lancaster Sound amounted to 0.76 Sv +/- 0.12 Sv and 48.45 mSv +/- 7.83 mSv respectively. The 26-year mean volume and freshwater fluxes through Davis Strait were 1.55 Sv +/- 0.29 Sv and 62.66 mSv +/- 11.67 mSv while the modeled Fram Strait branch provided very little (similar to 2%) freshwater into the Labrador Sea compared to the total CAA input. Compared to available observations, the model provides reasonable volume and freshwater fluxes, as well as sea ice thickness and concentration in the CAA. In Nares Strait and Lancaster Sound, volume flux anomalies were controlled by the sea surface height (SSH) gradient anomalies along the straits and freshwater anomalies were highly correlated with the volume anomalies. At least half of the variance in the time series of SSH gradient anomaly was due to SSH anomalies in northern Baffin Bay. The West Greenland Current (WGC) exhibits seasonality, with cross shelf flow (into the Labrador Sea) peaking in January/February/March, while reducing the northward flow across eastern Davis Strait. We hypothesize that the eddy-reduced northward flow of WGC results in the lower volume and SSH in Baffin Bay. This maximizes the SSH gradients between the Arctic Ocean and Baffin Bay, leading to maximum winter volume fluxes through Nares Strait and Lancaster Sound. Model limitations include the insufficient spatial resolution of atmospheric forcing (especially to account for the effects of local topography), the representation of river runoff into Hudson Bay and coastal buoyancy currents, low mobility of modeled ice, and incomplete depiction of ice arching. Many of these issues are expected to be resolved with increased model grid cell resolution, improved sea ice and ocean models and more realistic atmospheric

AB A research cruise was carried out over the Heng-Chun Ridge during June 27-July 1, 2010, near 21 degrees 34'N, 120 degrees 54'E, about 35 km south of Taiwan. The goal of the cruise was to determine if the location is an active generation site for internal tides and high-frequency nonlinear internal waves (NLIWs) in the northeastern South China Sea (SCS). The method was to sample a series of across-ridge sections using an underway conductivity-temperature-depth (UCTD) profiler and to conduct a time series at a fixed point atop the ridge using a CTD with lowered acoustic Doppler current profiler (LADCP) instrumentation. A hull-mounted ADCP and acoustic backscatter device were also operated throughout the cruise. The site was a very high energy region, with the northward Kuroshio Current exceeding 100 cm s(-1) and the primarily zonal barotropic tidal currents exceeding 140 cm s(-1). The most remarkable feature observed was a convex-type mode-2 NLIW with a westward-propagating core centered near 100 m depth. The wave was clearly visible in the velocity and backscatter data and had surface expressions visible both on radar and with the naked eye. The horizontal and vertical velocity structure was a good match for theoretical mode-2 waves in the SCS. The wave generation was consistent with local lee wave dynamics, which favored mode-2 generation over mode-1 at peak ebb tide given the currents, stratification, and bottom slope at the site. The wave could not be tracked farther west, and apparently did not escape the opposing Kuroshio.

AB Observations along 26.5 degrees N are used to examine the time mean structure of the Atlantic meridional overturning circulation (AMOC) in eddy-resolving simulations with the Hybrid Coordinate Ocean Model (HYCOM). The model results yield a 5 year mean AMOC transport of 18.2 Sv, compared to 18.4 Sv based on data. The modeled northward limb of the AMOC has a vertical structure similar to observations. The southward limb is shallower than observed but deeper than other ocean general circulation models and includes a secondary transport maximum near 4000 m corresponding to Nordic Seas Overflow Water. The modeled flow through the Florida Strait and the deep western boundary current (DWBC) east of Abaco, Bahamas, are also approximately consistent with observations. The model results are used to clarify the sources of the northward AMOC transport and to explore the circulation pattern of the southward transport in the western subtropical North Atlantic in the range 18-33 degrees N. About 14.1 Sv of the modeled northward AMOC transport is through the Florida Strait and the remainder through the mid-ocean, primarily in the Ekman layer, but also below 600 m. The modeled AMOC transport is about 2/3 surface water and 1/3 Antarctic Intermediate Water with no contribution from the thermocline water in between. In the western subtropical North Atlantic the model results depict a complicated deep circulation pattern, associated with the complex bathymetry. The DWBC flows southward then eastward in both the upper and lower North Atlantic Deep Water (NADW) layers but with different offshore recirculation pathways, and there exists a second, more northern branch of eastward flow in the lower NADW layer.

ID LAYERED CHALCOGENIDES CUS; 40 K; COVELLITE; BEHAVIOR; STATE
AB We present first-principles calculations of the structural and electronic properties of the CuS covellite material. The symmetry-lowering structural transition is well reproduced. However, the microscopic origin of the transition is unclear. The calculations firmly establish that the previously controversial Cu valency in this compound is 1.33. We also argue that recently reported high-temperature superconductivity (HTSC) in CuS is unlikely to occur in the stoichiometric defect-free material, since the determined Cu valency is too close to 1 to ensure proximity to a Mott-Hubbard state and superexchange spin fluctuations of considerable strength. On the other hand, one can imagine a related system with more holes per Cu in the same structural motif (e.g., due to defects or O impurities), in which case the combination of superexchange and a Fermi surface enlarged compared to that of CuS may lead to unconventional superconductivity, as in HTSC cuprates, but, unlike them, of an f-wave symmetry.

AB Simulated bidirectional reflectance distribution functions (BRDF) were compared with measurements made just beneath the water's surface. In Case I water, the set of simulations that varied the particle scattering phase function depending on chlorophyll concentration agreed more closely with the data than other models. In Case II water, however, the simulations using fixed phase functions agreed well with the data and were nearly indistinguishable from each other, on average. The results suggest that BRDF corrections in Case II water are feasible using single, average, particle scattering phase functions, but that the existing approach using variable particle scattering phase functions is still warranted in Case I water.

AB A seven-year old California sea lion (Zalophus californianus) presented with focally extensive, bilaterally symmetric, proliferative axillary skin lesions and preputial lesions. A second California sea lion in the same population presented with similar proliferative lesions on the underside of the tail. Histopathology revealed epidermal hyperplasia with severe hyperkeratosis, with proliferating keratinocytes forming broad, branching pegs that extended into the dermis. Pan-papillomaviral consensus PCR was used to obtain initial El sequence template and the complete genome was determined using a combination of rolling circle amplification and specific-primer PCR. Analysis revealed a novel papillomavirus, Zalophus californianus papillomavirus 1 (ZcPV1), with seven open reading frames encoding five early proteins (E6, E7, El, E2 and E4) and two late proteins (L1 and L2). Phylogenetic analysis revealed that (ZcPV1) is most closely related to Equine papillomavirus 1 (EcPV1) in the genus Zetapapillomavirus, and Canine papillomaviruses 3 and 4 (CPV3, CPV4) in the genus Chipapillomavirus. The lesions regressed without intervention over a period of several months. (C) 2011 Elsevier B.V. All rights reserved.

AB We present the results of a laboratory study on bubble clouds characteristics (length, depth of penetration, width, and void fraction) in fresh water for wind speeds from 9 to 16 m s(-1). Temporal and spatial changes of these characteristics and their statistics were extracted from video images from side and top views. Cloud characteristics were scaled with the period T, wavelength L, phase speed c, and significant wave height H-s of the dominant wave. The lifetime of the bubble cloud comprises formation, growth and decay stages. The bubble cloud moves forward horizontally with the wave for the initial 1/3 of the wave period at approximately half the wave phase speed (0.5c). The subsequent dominant motion of the bubble cloud in the wave trough is vertical with a mean speed half that of rising bubbles. The void fraction is as high as 80-99% in the first quarter (0.25T) of the bubble cloud lifetime corresponding to wave phase of up to 90 degrees. The void fraction decreases steadily to about 20-30% at 0.7T (wave phase of similar to 270 degrees). Probability density functions of the bubble cloud characteristics show that the bubble cloud length varies from 0.1L to 0.7L; the bubble cloud thickness ranges from 0.5H(s) to 2H(s). Scaled bubble cloud characteristics and the cloud void fraction vary weakly with the wind speed for the growth stage. Residual void fractions can persist for long times O(100T).

AB Background: Whether seroresponse to a vaccine such as hepatitis B virus (HBV) vaccine can provide a measure of the functional immune status of HIV-infected persons is unknown. This study evaluated the relationship between HBV vaccine seroresponses and progression to clinical AIDS or death.
Methods and Findings: From a large HIV cohort, we evaluated those who received HBV vaccine only after HIV diagnosis and had anti-HBs determination 1-12 months after the last vaccine dose. Non-response and positive response were defined as anti-HBs <10 and >= 10 IU/L, respectively. Participants were followed from date of last vaccination to clinical AIDS, death, or last visit. Univariate and multivariable risk of progression to clinical AIDS or death were evaluated with Cox regression models. A total of 795 participants vaccinated from 1986-2010 were included, of which 41% were responders. During 3,872 person-years of observation, 122 AIDS or death events occurred (53% after 1995). Twenty-two percent of non-responders experienced clinical AIDS or death compared with 5% of responders (p<0.001). Non-response to HBV vaccine was associated with a greater than 2-fold increased risk of clinical AIDS or death (HR 2.47; 95% CI, 1.38-4.43) compared with a positive response, after adjusting for CD4 count, HIV viral load, HAART use, and delayed type hypersensitivity skin test responses (an in vivo marker of cell-mediated immunity). This association remained evident among those with CD4 count >= 500 cells/mm(3) (HR 3.40; 95% CI, 1.39-8.32).
Conclusions: HBV vaccine responses may have utility in assessing functional immune status and risk stratificating HIV-infected individuals, including those with CD4 count >= 500 cells/mm(3).

AB Decompression sickness (DCS; 'the bends') is a disease associated with gas uptake at pressure. The basic pathology and cause are relatively well known to human divers. Breath-hold diving marine mammals were thought to be relatively immune to DCS owing to multiple anatomical, physiological and behavioural adaptations that reduce nitrogen gas (N-2) loading during dives. However, recent observations have shown that gas bubbles may form and tissue injury may occur in marine mammals under certain circumstances. Gas kinetic models based on measured time-depth profiles further suggest the potential occurrence of high blood and tissue N-2 tensions. We review evidence for gas-bubble incidence in marine mammal tissues and discuss the theory behind gas loading and bubble formation. We suggest that diving mammals vary their physiological responses according to multiple stressors, and that the perspective on marine mammal diving physiology should change from simply minimizing N-2 loading to management of the N-2 load. This suggests several avenues for further study, ranging from the effects of gas bubbles at molecular, cellular and organ function levels, to comparative studies relating the presence/absence of gas bubbles to diving behaviour. Technological advances in imaging and remote instrumentation are likely to advance this field in coming years.

TI THE SWIFT BURST ALERT TELESCOPE PERSPECTIVE ON NON-THERMAL EMISSION IN

AB The search for diffuse non-thermal, inverse Compton (IC) emission from galaxy clusters at hard X-ray energies has been underway for many years, with most detections being either of low significance or controversial. In this work, we investigate 14-195 keV spectra from the Swift Burst Alert Telescope (BAT) all-sky survey for evidence of non-thermal excess emission above the exponentially decreasing tail of thermal emission in the flux-limited HIFLUGCS sample. To account for the thermal contribution at BAT energies, XMM-Newton EPIC spectra are extracted from coincident spatial regions so that both thermal and non-thermal spectral components can be determined simultaneously. We find marginally significant IC components in six clusters, though after closer inspection and consideration of systematic errors we are unable to claim a clear detection in any of them. The spectra of all clusters are also summed to enhance a cumulative non-thermal signal not quite detectable in individual clusters. After constructing a model based on single-temperature fits to the XMM-Newton data alone, we see no significant excess emission above that predicted by the thermal model determined at soft energies. This result also holds for the summed spectra of various subgroups, except for the subsample of clusters with diffuse radio emission. For clusters hosting a diffuse radio halo, a relic, or a mini-halo, non-thermal emission is initially detected at the similar to 5 sigma confidence level-driven by clusters with mini-halos-but modeling and systematic uncertainties ultimately degrade this significance. In individual clusters, the non-thermal pressure of relativistic electrons is limited to less than or similar to 10% of the thermal electron pressure, with stricter limits for the more massive clusters, indicating that these electrons are likely not dynamically important in the central regions of clusters.

TI Spin Waves and Revised Crystal Structure of Honeycomb Iridate Na2IrO3
SO PHYSICAL REVIEW LETTERS
LA English
DT Article
AB We report inelastic neutron scattering measurements on Na2IrO3, a candidate for the Kitaev spin model on the honeycomb lattice. We observe spin-wave excitations below 5 meV with a dispersion that can be accounted for by including substantial further-neighbor exchanges that stabilize zigzag magnetic order. The onset of long-range magnetic order below T-N = 15.3 K is confirmed via the observation of oscillations in zero-field muon-spin rotation experiments. Combining single-crystal diffraction and density functional calculations we propose a revised crystal structure model with significant departures from the ideal 90 degrees Ir-O-Ir bonds required for dominant Kitaev exchange.

AB We have discovered five millisecond pulsars (MSPs) in a survey of 14 unidentified Fermi Large Area Telescope sources in the southern sky using the Parkes radio telescope. PSRs J0101-6422, J1514-4946, and J1902-5105 reside in binaries, while PSRs J1658-5324 and J1747-4036 are isolated. Using an ephemeris derived from timing observations of PSR J0101-6422 (P = 2.57 ms, DM = 12 pc cm(-3)), we have detected gamma-ray pulsations and measured its proper motion. Its gamma-ray spectrum (a power law of Gamma = 0.9 with a cutoff at 1.6 GeV) and efficiency are typical of other MSPs, but its radio and gamma-ray light curves challenge simple geometric models of emission. The high success rate of this survey-enabled by selecting gamma-ray sources based on their detailed spectral characteristics-and other similarly successful searches indicate that a substantial fraction of the local population of MSPs may soon be known.

TI Effects of stencil width on surface ocean geostrophic velocity and
vorticity estimation from gridded satellite altimeter data
SO JOURNAL OF GEOPHYSICAL RESEARCH-OCEANS
LA English
DT Article
ID DIFFERENTIATION; TOPEX/POSEIDON; CIRCULATION; RESOLUTION
AB This paper examines the effect of "stencil width" on surface ocean geostrophic velocity and vorticity estimated from differentiating gridded satellite altimeter sea surface height products. In oceanographic applications, the value of the first derivative at a central grid point is generally obtained by differencing the sea surface heights at adjacent grid points. This is called a "three-point stencil centered difference". Here the stencil width is increased from three to five, seven, and nine points, using well-known formulae from the numerical analysis literature. The discrepancies between velocities computed with successive stencils decreases with increasing stencil width, suggesting that wide stencil results are more reliable. Significant speed-dependent biases (up to 10-20%) are found between results computed from three-point stencils versus those computed from wider stencils. The geostrophic velocity, and the variance of geostrophic velocity, are underestimated with thin stencils. Similar results are seen in geostrophic velocities computed from high-resolution model output. In contrast to the case when three-point stencils are used, wider stencils yield estimates of the anisotropy of velocity variance that are insensitive to the differences in grid spacing between two widely used altimeter products. Three-point stencils yield incorrect anisotropies on the 1/4 degrees anisotropic AVISO grid; we recommend the use of 7-point stencils. Despite the demonstrated inadequacies of the three-point stencils, the conclusions of earlier studies based on them, that the zonally averaged midlatitude eddy kinetic energy field is nearly isotropic, are found to pertain also with wider stencils. Finally, the paper also examines the strengths and limitations of applying noise-suppressing differentiators, versus classic centered differences, to altimeter data.

ID MAGNETIC-PROPERTIES; ERRH4B4; TRANSITION
AB We study a bilayer consisting of an ordinary superconductor and a magnet with a spiral magnetic structure of the Ho type. We use a self-consistent solution of the Bogolioubov-de Gennes equations to evaluate the pair amplitude, the transition temperature, and the thermodynamic functions, namely, the free energy and entropy. We find that for a range of thicknesses of the magnetic layer the superconductivity is reentrant with temperature T: as one lowers T the system turns superconducting, and when T is further lowered it turns normal again. This behavior is reflected in the condensation free energy and the pair potential, which vanish both above the upper transition and below the lower one. The transition is strictly reentrant: the low and high temperature phases are the same. The entropy further reveals a range of temperatures where the superconducting state is less ordered than the normal one.

AB Shipboard magnetic field data collected over Chesapeake Bay exhibit low-amplitude, short-wavelength anomalies that most likely indicate shallow concentrations of heavy mineral sediments. Piston core layers and black sand beach samples exhibit enhanced magnetic susceptibilities and carry remanent magnetization, with mineralogical analyses indicating ilmenite and trace magnetite and/or maghemite and hematite. The anomalies are subtle and would be filtered as noise using traditional approaches, but can instead be highlighted using spectral methods, thus providing nearly continuous coverage along survey tracks. The distribution of the anomalies provides constraints on relevant sorting mechanisms. Comparisons to sonar data and previous grab samples show that two of three areas surveyed exhibit short-wavelength anomalies that are clustered over sand-covered areas, suggesting initial sorting through settling mechanisms. This is supported by a correlation between core magnetic susceptibility and grain size. Near the Choptank River, where sediment resuspension is wave-dominated, anomalies show a sharp decrease with seafloor depth that cannot be explained by signal attenuation alone. In Pocomoke Sound, where both tidal currents and wave-action impact sediment resuspension, anomalies show a more gradual decrease with depth. Near the mouth of the bay, where there is a higher influx of sediments from the continental shelf, short-wavelength anomalies are isolated and do not appear to represent heavy mineral sand concentrations. These combined observations suggest the importance of further sorting by erosional processes in certain parts of the bay. Additionally, comparisons of these data to cores sampling pre-Holocene sediments suggest that the sorting of heavy minerals in higher energy, shallow water environments provides a mechanism for correlations between core magnetic susceptibility and sea-level changes.

ID AMORPHOUS-ALLOYS; FORMING ABILITY; FE; TEMPERATURE; CO
AB A series of ferromagnetic metallic glasses with compositions (Fe,Co)(78)Mo-1(B,P,Si)(21) are shown to possess good thermal stability and soft magnetic performance. The thermal stability inside the supercooled liquid temperature region was evaluated using Kissinger analysis of primary crystallization, time-temperature-transformation (TTT) diagrams, and the extent of the supercooled liquid region (Delta T-x). The phosphorus-free alloy, Fe78Mo1B15Si6, had an activation energy (E-a) of 414 kJ/mol, Delta T-x similar to 50 K, and began devitrifying after about 1 min at 730 K. By way of comparison, the phosphorus-containing alloy, Fe78Mo1B13P6Si2, had an E-a of 440 kJ/mol, Delta T-x similar to 45 K, and began devitrification after 10 min at 730 K. High saturation magnetization (mu M-0(s) similar to 1.45-1.55 T) and low coercivity (H-c similar to 20 A/m) are demonstrated across the composition range. Core loss measurements of toroidal cores are shown to be less than 12 W/cm(3) at 1 T, maximum induction amplitude (under both sinusoidal and square waveforms). Trends were established for magnetic and thermal stability as a function of metalloid and magnetic transition metal composition. (C) 2012 American Institute of Physics.

AB In this paper we report the superconducting quantum interference device (SQUID) and magnetic force microscope (MFM) measurements of magnetic multilayer nanoscale antidot samples. The systems used consist of Fe(60 angstrom)/Ni(90 angstrom)/Fe(60 angstrom) (FeNiFe) multilayer antidots with hexagonal lattice fabricated on nanochannel glass (NCG) substrates with antidot diameters of 260, 362, 530, and 800 nm. The results indicate that the domain structure is commensurate with the holes due to the pinning effect of the antidots. This pinning effect is inversely proportional to the diameter of the antidots. The field dependent MFM data show that the hexagonal antidot lattice induces a weak anisotropy with the magnetic easy axis along the nearest neighbor direction. The unit cell in the antidot arrays could be used for data storage. (C) 2012 American Institute of Physics. [http://dx.doi.org/10.1063/1.3694011]

AB ZrW2O8 is known for its isotropic negative thermal expansion over a wide of range of temperature from 272 to 777 degrees C. However, ZrW2O8 melts incongruently at 1257 degrees C and is stable only over a short temperature interval between 1105 and 1257 degrees C. This makes the growth of single crystals a formidable challenge. In order to study the intrinsic properties of this compound, a repeatable, viable single crystal growth strategy is required. Here we report a simple, self-seeding, self-fluxing single crystal growth process which resulted in single crystals of ZrW2O8 up to about 4 mm in size. Grown crystals were characterized by X-ray diffraction (XRD), Raman spectroscopy and Fourier transform infrared (FTIR) spectroscopy. Mechanical properties of the crystals were studied using nanoindentation. (C) 2012 Elsevier B.V. All rights reserved.

AB Films of nanocrystalline PbSe were fabricated with a set of structurally varied short-chain dicarboxylic acids. Oxidation rates were studied via NIR spectroscopy to determine the effect of the structure of the diacid ligands on film stability under ambient conditions. Ligands favoring a non-bridging bonding mode were found to provide the best protection against oxidation, while among ligands expected to bridge between adjacent nanocrystals in the films, those with shorter chain lengths conferred better oxidative stability. Electronic coupling was observed as a red shift in the optical data of the ground excitonic peak of the PbSe films and found to be strongly influenced by the structure of the ligand. Transport measurements were made in air using thin-film transistors that were treated with a thin Al2O3 coating via remote plasma ALD. Films prepared using fumaric, maleic, and oxalic acids yielded mobility numbers of 2.5 x 10(-5), 3.7 x 10(-5), and 1.6 x 10(-3) cm(2)/V.s, respectively. Results suggest that the internanocrystal distance is the major contributor to electron mobility through the nanocrystalline films, while the electronic coupling is heavily influenced by multiple factors related to the structure of the surface ligands in addition to the internanocrystal distance.

AB Six Arctic Ocean Model Intercomparison Project model simulations are compared with estimates of sea ice thickness derived from pan-Arctic satellite freeboard measurements (2004-2008); airborne electromagnetic measurements (2001-2009); ice draft data from moored instruments in Fram Strait, the Greenland Sea, and the Beaufort Sea (1992-2008) and from submarines (1975-2000); and drill hole data from the Arctic basin, Laptev, and East Siberian marginal seas (1982-1986) and coastal stations (1998-2009). Despite an assessment of six models that differ in numerical methods, resolution, domain, forcing, and boundary conditions, the models generally overestimate the thickness of measured ice thinner than similar to 2 m and underestimate the thickness of ice measured thicker than about similar to 2 m. In the regions of flat immobile landfast ice (shallow Siberian Seas with depths less than 25-30 m), the models generally overestimate both the total observed sea ice thickness and rates of September and October ice growth from observations by more than 4 times and more than one standard deviation, respectively. The models do not reproduce conditions of fast ice formation and growth. Instead, the modeled fast ice is replaced with pack ice which drifts, generating ridges of increasing ice thickness, in addition to thermodynamic ice growth. Considering all observational data sets, the better correlations and smaller differences from observations are from the Estimating the Circulation and Climate of the Ocean, Phase II and Pan-Arctic Ice Ocean Modeling and Assimilation System models.

AB This study aimed to improve the accuracy and robustness of a real-time assistive human machine interface system by classifying between the controlled movements related tongue-movement ear pressure (TMEP) signals and the interfering signals. The controlled movement TMEP signals were collected during left, right, up, down, flicking and pushing tongue motions. The TMEP signals were processed and classified using detection, segmentation, feature extraction and classification. The segmented signals were decomposed into the time-scale domain using a wavelet packet transform. The variance of the wavelet packet coefficients and its ratio between low-to-high scales were defined as features and the intended tongue movement commands and interfering signals were classified using both a Bayesian and support vector machine (SVM) classifiers for comparison. The average classification accuracy for discriminating between the controlled movements and the interfering signals achieved 97.8% (Bayesian) and 98.5% (SVM). The classifiers were robust remaining at a similar performance level when generalised interferences from all subjects were used. It was shown that the Bayesian classifier performed better than the SVM in a real-time environment. The approach of combining the Bayesian classifier and the wavelet packet transform provides a robust and efficient method for a real-time assistive human machine interface based on tongue-movement ear pressure signals.

AB Background: A major concern in malaria vaccine development is genetic polymorphisms typically observed among Plasmodium isolates in different geographical areas across the world. Highly polymorphic regions have been observed in Plasmodium falciparum and Plasmodium vivax antigenic surface proteins such as Circumsporozoite protein (CSP), Duffy-binding protein (DBP), Merozoite surface protein-1 (MSP-1), Apical membrane antigen-1 (AMA-1) and Thrombospondin related anonymous protein (TRAP).
Methods: Genetic variability was assessed in important polymorphic regions of various vaccine candidate antigens in P. vivax among 106 isolates from the Amazon Region of Loreto, Peru. In addition, genetic diversity determined in Peruvian isolates was compared to population studies from various geographical locations worldwide.
Results: The structured diversity found in P. vivax populations did not show a geographic pattern and haplotypes from all gene candidates were distributed worldwide. In addition, evidence of balancing selection was found in polymorphic regions of the trap, dbp and ama-1 genes.
Conclusions: It is important to have a good representation of the haplotypes circulating worldwide when implementing a vaccine, regardless of the geographic region of deployment since selective pressure plays an important role in structuring antigen diversity.

TI Analysis of a ray-tracing model for gravity waves generated by
tropospheric convection
SO JOURNAL OF GEOPHYSICAL RESEARCH-ATMOSPHERES

DT Article
ID THERMOSPHERIC RESPONSES; INTERNAL WAVES; WINDS; SHEAR
AB The Vadas-Fritts ray-tracing model for convectively generated gravity waves is analyzed using the stationary phase approximation and is interpreted in terms of a ray Jacobian approximated by the density of rays. The Vadas-Fritts model launches rays from the convective source region, with initial conditions for the ray-tracing deduced from a near-field integral representation. In the far-field the rays are binned in space-time grid cells. The contribution of each ray to the spatial wave amplitude is determined by its spectral amplitude and by the local density of rays within the grid cells. The present analysis accomplishes two things. First, the stationary phase analysis gives the formal initial conditions for the ray-tracing, which mostly agree with the Vadas-Fritts initialization but also suggest some refinements. Secondly, the Jacobian and ray-density analysis shows how the Vadas-Fritts model can be generalized to follow a beam of rays with a single moving grid cell.

ID QUANTUM CASCADE LASER; ABSORBER; DESIGN; FILMS
AB Metamaterial absorbers with nearly 100% absorption in the terahertz (THz) spectral band have been designed and fabricated using a periodic array of aluminum (Al) squares and an Al ground plane separated by a thin silicon dioxide (SiO2) dielectric film. The entire structure is less than 1.6 mm thick making it suitable for the fabrication of microbolometers or bi-material sensors for THz imaging. Films with different dielectric layer thicknesses exhibited resonant absorption at 4.1, 4.2, and 4.5 THz with strengths of 98%, 95%, and 88%, respectively. The measured absorption spectra are in good agreement with simulations using finite element modeling. (C) 2012 American Institute of Physics. [http://dx.doi.org/10.1063/1.3693407]

TI Exchange anisotropy in the nanostructured MnAl system
SO APPLIED PHYSICS LETTERS

DT Article
ID MAGNETIC-PROPERTIES; SILVER-MANGANESE; AL; ALLOYS; PHASE; FILMS; BASE
AB In this letter, we report on the achievement of exchange anisotropy magnitude in a nanostructured Mn55Al45 alloy fabricated by rapid solidification with large exchange bias values (H-E approximate to 13 kOe at 10K) and a blocking temperature of T-B similar to 95 K. Field-cooled magnetization loops show a prominent exchange bias for T < T-B signaling the simultaneous presence of antiferromagnetic and ferromagnetic phases at these temperatures. Structural probes confirm a majority presence of the high-temperature metastable hexagonal epsilon-MnAl in the as-solidified state with an intriguing double-Bragg peak structure indicative of phase separation. The observed exchange bias is hypothesized to originate from an intimate mixture of antiferromagnetic and nanoscaled ferromagnetic phases or dual mictomagnetic phases, approximating a cluster glass with well-defined variations in the local Mn concentration of the composition and leading to Mn-rich and Mn-poor regions with antiferromagnetic and ferromagnetic characters, respectively.

AB Using a low power beam of ultrashort THz pulses that propagate in the ambient laboratory environment we have measured the rotational signatures of small molecule vapors at frequencies within the atmospheric transmission windows. We investigate two types of apparatus. In the first type the THz beam propagates along a 6.7 meter round trip path that is external to the spectrometer, and which contains a long sample tube (5.4 meter round trip path) that holds the analyte vapor. The environment of the tube is controlled to simulate dry or humid conditions. In the second apparatus the THz beam propagates over a much longer 170 meter round trip path with analyte vapor contained in a relatively short 1.2 meter round trip path sample chamber. We describe the rotational signatures for each apparatus in the presence of the strong interference from water vapor absorption. For the shorter path long-tube apparatus we find that the peak detection sensitivity is sufficient to resolve a 1% absorption feature. For the more challenging 170 meter path apparatus we find that the peak detection sensitivity is sufficient to resolve a 3-5% absorption feature. The experiments presented here represent a first step towards using ultrashort THz pulses for coherent broad band detection of small molecule gases and vapors under ambient conditions.

AB Numerical simulations based on the ACDM model of cosmology predict a large number of as yet unobserved Galactic dark matter satellites. We report the results of a Large Area Telescope (LAT) search for these satellites via the gamma-ray emission expected from the annihilation of weakly interacting massive particle (WIMP) dark matter. Some dark matter satellites are expected to have hard gamma-ray spectra, finite angular extents, and a lack of counterparts at other wavelengths. We sought to identify LAT sources with these characteristics, focusing on gamma-ray spectra consistent with WIMP annihilation through the b (b) over bar channel. We found no viable dark matter satellite candidates using one year of data, and we present a framework for interpreting this result in the context of numerical simulations to constrain the velocity-averaged annihilation cross section for a conventional 100 GeV WIMP annihilating through the b (b) over bar channel.

AB We report on a systematic investigation of the gamma-ray properties of 120 hard X-ray-selected Seyfert galaxies classified as "radio-quiet" objects, utilizing the three-year accumulation of Fermi Large Area Telescope (LAT) data. Our sample of Seyfert galaxies is selected using the Swift Burst Alert Telescope 58 month catalog, restricting the analysis to the bright sources with average hard X-ray fluxes F14-195 keV >= 2.5 x 10(-11) erg cm(-2) s(-1) at high Galactic latitudes (|b| > 10 degrees). In order to remove "radio-loud" objects from the sample, we use the "hard X-ray radio loudness parameter," RrX, defined as the ratio of the total 1.4 GHz radio to 14-195 keV hard X-ray energy fluxes. Among 120 X-ray bright Seyfert galaxies with RrX < 10(-4), we did not find a statistically significant g-ray excess (TS > 25) positionally coincident with any target Seyferts, with possible exceptions of ESO 323-G077 and NGC 6814. The mean value of the 95% confidence level gamma-ray upper limit for the integrated photon flux above 100 MeV from the analyzed Seyferts is similar or equal to 4 x 10(-9) photons cm(-2) s(-1), and the upper limits derived for several objects reach similar or equal to 1 x 10(-9) photons cm(-2) s(-1). Our results indicate that no prominent gamma-ray emission component related to active galactic nucleus activity is present in the spectra of Seyferts around GeV energies. The Fermi-LAT upper limits derived for our sample probe the ratio of gamma-ray to X-ray luminosities L-gamma/L-X < 0.1, and even <0.01 in some cases. The obtained results impose novel constraints on the models for high-energy radiation of "radio-quiet" Seyfert galaxies.

AB Recent STEREO observations enabled the study of the properties of EUV waves in more detail. They were found to have a three-dimensional (3D) dome-shaped structure. We investigate, by means of 3D MHD simulations, the formation of EUV waves as the result of the interaction of twisted coronal magnetic loops. The numerical simulation is initialized with an idealized dipolar active region and is performed under coronal (low beta) conditions. A sheared rotational motion is applied to the central parts of both the positive and negative flux regions at the photosphere so that the flux tubes in between them become twisted. We find that the twisting motion results in a dome-shaped structure followed in space by a dimming and in time by an energy release (flare). The rotation of the sunspots is the trigger of the wave which initially consists of two fronts that later merge together. The resulting EUV wave propagates nearly isotropically on the disk and similar to 2 times faster in the upward direction. The initial stage of the evolution is determined by the driver, while later the wave propagates freely with a nearly Alfvenic speed.

AB We develop a tricomponent (ternary) hydrodynamic model for multiphase flows of biomass and solvent mixtures, which we employ to simulate biofilm. In this model, the three predominant effective components in biofilms, which are the extracellular polymeric substance (EPS) network, the bacteria, and the effective solvent (consisting of the solvent and nutrient, etc.), are modeled explicitly. The tricomponent fluid mixture is assumed incompressible as a whole, while intercomponent mixing, dissipation, and conversion are allowed among the effective components. Bacterial growth and EPS production due to the growing bacterial population are modeled in the biomass transport equations. Bacterial decay due to starvation and natural causes is accounted for in the bacterial population dynamics to capture the possible bacterial population reduction due to the depletion of the nutrient. In the growth regime for biofilms, the mixture behaves like a multiphase viscous fluid, in which the molecular relaxation is negligible in the corresponding time scale. In this regime, the dynamics of biofilm growth in the solvent (water) are simulated using a two-dimensional finite difference solver that we developed, in which the distribution and evolution of the EPS and bacterial volume fractions are investigated. The hydrodynamic interaction between the biomass and the solvent flow field is also simulated in a shear cell environment, demonstrating the spatially and temporally heterogeneous distribution of the EPS and bacteria under shear. This model together with the numerical codes developed provides a predictive tool for studying biomass-flow interaction and other important biochemical interactions in the biofilm and solvent fluid mixture.

AB On-line sample preconcentration is an essential tool in the development of microfluidic-based separation platforms. In order to become more competitive with traditional separation techniques, the community must continue to develop newer and more novel methods to improve detection limits, remove unwanted sample matrix components that disrupt separation performance, and enrich/purify analytes for other chip-based actions. Our goal in this review is to familiarize the reader with many of the options available for on-chip concentration enhancement with a focus on those manuscripts that, in our assessment, best describe the fundamental principles that govern those enhancements. Sections discussing both electrophoretic and nonelectrophoretic modes of preconcentration are included with a focus on device design and mechanisms of preconcentration. This review is not meant to be a comprehensive collection of every available example, but our hope is that by learning how on-line sample concentration techniques are being applied today, the reader will be inspired to apply these techniques to further enhance their own programs.

TI Use of vertical temperature gradients for prediction of tidal flat
sediment characteristics
SO JOURNAL OF GEOPHYSICAL RESEARCH-OCEANS
LA English
DT Article
ID MUDDY INTERTIDAL SEDIMENTS; THERMAL-CONDUCTIVITY; SANDS; KOREA
AB Sediment characteristics largely govern tidal flat morphologic evolution; however, conventional methods of investigating spatial variability in lithology on tidal flats are difficult to employ in these highly dynamic regions. In response, a series of laboratory experiments was designed to investigate the use of temperature diffusion toward sediment characterization. A vertical thermistor array was used to quantify temperature gradients in simulated tidal flat sediments of varying compositions. Thermal conductivity estimates derived from these arrays were similar to measurements from a standard heated needle probe, which substantiates the thermistor methodology. While the thermal diffusivities of dry homogeneous sediments were similar, diffusivities for saturated homogeneous sediments ranged approximately one order of magnitude. The thermal diffusivity of saturated sand was five times the thermal diffusivity of saturated kaolin and more than eight times the thermal diffusivity of saturated bentonite. This suggests that vertical temperature gradients can be used for distinguishing homogeneous saturated sands from homogeneous saturated clays and perhaps even between homogeneous saturated clay types. However, experiments with more realistic tidal flat mixtures were less discriminating. Relationships between thermal diffusivity and percent fines for saturated mixtures varied depending upon clay composition, indicating that clay hydration and/or water content controls thermal gradients. Furthermore, existing models for the bulk conductivity of sediment mixtures were improved only through the use of calibrated estimates of homogeneous end-member conductivity and water content values. Our findings suggest that remotely sensed observations of water content and thermal diffusivity could only be used to qualitatively estimate tidal flat sediment characteristics.

AB The effects of multiwall carbon nanotubes (MWCNT), nanolayered silicate (nanoclay), and trisilanolphenyl-functionalized polyhedral oligomeric silsesquioxane (PUSS) on the rheology and mechanical properties of an oligomeric polydiamine and the polyurea formed by its reaction with isocyanate were measured. The MWCNT and nanoclay increase the viscosity of the polydiamine and form a flocculated filler network at very low concentrations (<1%). This network imparts a strong strain-dependence to the dynamic modulus. These effects are absent with PUSS, which primarily affects the polyurea chemistry. The tensile modulus of the cured polyurea is higher for all three additives, with PUSS significantly toughening the material, provided adjustments to the stoichiometry are made.

AB By combining first-principles calculations and experimental x-ray photoemission (XPS) spectroscopy measurements, we investigate the electronic structure of potential Li-ion battery cathode materials LiMPO4 (M = Mn, Fe, Co, Ni) to uncover the underlying mechanisms that determine small hole polaron formation and migration. We show that small hole polaron formation depends on features in the electronic structure near the valence-band maximum and that, calculationally, these features depend on the methodology chosen for dealing with the correlated nature of the transition-metal d-derived states in these systems. Comparison with experiment reveals that a hybrid functional approach is superior to GGA + U in correctly reproducing the XPS spectra. Using this approach, we find that LiNiPO4 cannot support small hole polarons, but that the other three compounds can. The migration barrier is determined mainly by the strong- or weak-bonding nature of the states at the top of the valence band, resulting in a substantially higher barrier for LiMnPO4 than for LiCoPO4 or LiFePO4.

AB Fundamental physics and chemistry underlying nanotube synthesis and characteristics have not been fully understood. To facilitate this understanding, the concept of component seed, component droplet, and component nanowire for nanotube synthesis and characteristics has been introduced. This concept generalizes the shell model for nanotubes. It vastly broadens our ability to explain nanotube materials characteristics that could not otherwise be explained. Experiments widely corroborate with the present findings. They lend support to the concept of component seeds and component droplets. Size-dependent and solubility-dependent melting point depressions have been studied. They provide new insight and uncover the basic causes of melting (nonmelting) of the catalyst nanoparticles. They also elucidate nanotube growth, employing metal nanopartides at temperatures lower than their melting points. The concept of component seed (droplet) also successfully explains nanotube branching. In light of this concept, growth mechanisms available in the literature have been modified.

AB Individuals who perform optimally in extreme conditions, such as elite military warriors, can provide valuable insight into the neurobehavioral mechanisms underlying extraordinary performance. In the current study, we examined the degree to which Navy SEALs, when compared with healthy volunteers, could show more right anterior insula activation when shifting from anticipating one emotion to another during functional MRI. Consistent with our hypothesis, SEALs showed attenuated insula activation to negative image relative to positive image anticipation and greater right anterior insula activation during affective set-shifting. These findings suggest that elite warriors show combined (a) minimal reactivity during negative stimuli and (b) an enhanced ability to efficiently change their physiological state. These neural changes may underlie their ability to perform well in stressful situations. NeuroReport 23:234-239 (C) 2012 Wolters Kluwer Health vertical bar Lippincott Williams & Wilkins.

AB Significant efforts to develop both laboratory and field-based detection assays for an array of potential biological threats started well before the anthrax attacks of 2001 and have continued with renewed urgency following. While numerous assays and methods have been explored that are suitable for laboratory utilization, detection in the field is often complicated by requirements for functionality in austere environments, where limited cold-chain facilities exist. In an effort to overcome these assay limitations for Bacillus anthracis, one of the most recognizable threats, a series of single domain antibodies (sdAbs) were isolated from a phage display library prepared from immunized llamas. Characterization of target specificity, affinity, and thermal stability was conducted for six sdAb families isolated from rounds of selection against the bacterial spore. The protein target for all six sdAb families was determined to be the S-layer protein EA1, which is present in both vegetative cells and bacterial spores. All of the sdAbs examined exhibited a high degree of specificity for the target bacterium and its spore, with affinities in the nanomolar range, and the ability to refold into functional antigen-binding molecules following several rounds of thermal denaturation and refolding. This research demonstrates the capabilities of these sdAbs and their potential for integration into current and developing assays and biosensors.

AB The use of thermal desorption systems for the analysis of trace vapors typically requires establishing a calibration curve from vapors generated with a permeation tube. The slow equilibration time of permeation tubes causes such an approach to become laborious when covering a wide dynamic range. Furthermore, many analytes of interest, such as explosives, are not available as permeation tubes. A method for easily and effectively establishing calibration curves for explosive vapor samples via direct deposition of standard solutions on thermal desorption tubes was investigated. The various components of the thermal desorption system were compared to a standard split/splitless inlet. Calibration curves using the direct liquid deposition method with a thermal desorption unit coupled to a cryo-focusing inlet were compared to a standard split/splitless inlet, and a statistical difference was observed but does not eliminate or deter the use of the direct liquid deposition method for obtaining quantitative results for explosive vapors.

TI Is the "Big Deal" Dying?
SO SERIALS REVIEW
LA English
DT Article
AB This installment of Balance Point presents a series of written interviews with a variety of participants in the current debate over the possible death of the "big deal." The written discussions with large and small publishers, information service providers, consortia leaders, and several library stakeholders present the plethora of issues for readers. It is evident from the submissions that the idea of opting out of the "big deal," or at least the debates surrounding the discussions, is gaining momentum. The problems are important and often controversial. Most authors agree that the "big deal" is not dead yet, and some think it may never die completely. (C) 2012 Elsevier Inc. All rights reserved.

AB Near-ground aerosol fogs were applied in the Chihuahua Desert of New Mexico, which has widely spaced, low shrub vegetation. Near-ground fog dispersion was measured remotely with a light detection and ranging (lidar) system. Local atmospheric turbulence and stability were continuously measured with 3-axis sonic anemometers during aerosol treatments. Lidar-measured plume area coverage and spread were related to the simultaneous local-scale weather, including both convective boundary layers (CBL) and stable boundary layers (SBL). A modified bulk stability ratio (SRm) was used to characterize the stability conditions near the ground. Time averages appropriate to the SBL were determined using the multidimensional decomposition technique and matched to the short spray time periods in the CBL. The widest, most effective, near-ground coverage was obtained from insect fogger applications conducted during relatively high wind speeds: U > 1 m s(-1) stable conditions, and U > 3 m s(-1) in unstable conditions. In general, spraying during SBLs was more efficient than during CBLs, with less material wasted and better consistency of coverage in the target zone nearest the ground. There was no significant difference in spray coverage or plume dispersion between the handheld thermal fogger and the ultra-low volume (cold fogger) applicator used.

AB Introduction. Risk for post-traumatic stress disorder (PTSD) varies in part due to the nature of the traumatic event involved. Both injury and return from combat pose high risk of PTSD symptoms. How different injuries may predispose towards PTSD is less well understood.
Methods. A retrospective record review was conducted from 1402 service members who had returned to Naval Medical Center San Diego from Iraq or Afghanistan and who had completed the PTSD Checklist as part of their post-deployment screening. Rates of PTSD were examined in relation to mechanism of injury.
Results. Of those without injury, 8% met Diagnostic and Statistical Manual criteria for PTSD. Thirteen percent of those with a penetrating injury, 29% with blunt trauma, and 33% with combination injuries met criteria for PTSD. PTSD severity scores varied significantly according to type of injury.
Discussion. The World War I concept of "shell shock" implied that blast-related injuries were more likely to result in psychological symptoms than were other injuries. These data may support that idea. Circumstance of injury, population differences, and reporting bias could also have influenced the results.
Conclusion. These results suggest that service members with blunt or combination injuries merit particular attention when screening for PTSD.

AB Using the Aerosol Through Plasma (A-T-P) method in conjunction with simple chemical techniques a variety of complex and novel nanoparticle architectures were created. A-T-P was used to make metal core/carbon shell nanoparticles (ca. 50 nm diameter) of Sn/Carbon, which have potential for application as high energy density battery anodes for hybrid and electric vehicles. The initial Sn/carbon particles formed in the plasma were found to reach high capacity values, however presented poor cycle life possibly due to Sn volume expansion during lithiation and consequent shell breakage. Nonetheless, A-T-P Sn-core/carbon-shell material treated in acidic solution to partially remove tin, hence create void space, Sn/void space/carbon, showed higher discharge capacity and greatly improved cycling performance.

For different values of the parameters involved chaotic behaviour has been observed. Using the asymptotic methods of Bogoliubov, Krylov and Mitropolsky, non-resonant and resonant cases are discussed analytically. Computational studies of the system under consideration through poincare sections, time series, phase plots and poincare map confirm the chaotic behaviour or aging effect for the certain values of parameters of SWCNT.

AB Objective: Our aim was to determine if silent myocardial infarction (MI) is more common in women with type 2 diabetes than in men. Our secondary aim was to examine the relationships between silent MI and risk factors for cardiovascular disease.
Research design and methods: The Action to Control Cardiovascular Risk in Diabetes (ACCORD) database was used to determine if women had more silent MI on baseline electrocardiograms (ECGs) than did men with a similar unremarkable cardiovascular history. MI was diagnosed using ECG analysis according to the Minnesota code. Multivariable logistic regression analysis was used to compare demographic and clinical associations. Interactive effects of risk factors by gender were tested using a forward selection algorithm.
Results: Men were found to have a higher prevalence of silent MI on baseline ECGs than women (6% vs 4%, P = .001). Women had lower odds of silent MI than men after adjusting for other risk factors (OR = 0.80, P = .04). Race and ethnicity were significantly associated with silent MI (P = .02), with Asians having the highest and African Americans and Hispanics having lower odds relative to whites.
Conclusions: Our main findings provide no evidence that silent MI, as detected by the Minnesota code, was more common in women than in men in the ACCORD cohort. If, as in the general population, the women in ACCORD are found to have a higher heart disease mortality rate than the men, it seems unlikely that failure to recognize clinically silent heart disease in the years before study enrollment could be a major cause.

AB We describe a mission concept for a stand-alone Titan airplane mission: Aerial Vehicle for In-situ and Airborne Titan Reconnaissance (AVIATR). With independent delivery and direct-to-Earth communications, AVIATR could contribute to Titan science either alone or as part of a sustained Titan Exploration Program. As a focused mission, AVIATR as we have envisioned it would concentrate on the science that an airplane can do best: exploration of Titan's global diversity. We focus on surface geology/hydrology and lower-atmospheric structure and dynamics. With a carefully chosen set of seven instruments-2 near-IR cameras, 1 near-IR spectrometer, a RADAR altimeter, an atmospheric structure suite, a haze sensor, and a raindrop detector-AVIATR could accomplish a significant subset of the scientific objectives of the aerial element of flagship studies. The AVIATR spacecraft stack is composed of a Space Vehicle (SV) for cruise, an Entry Vehicle (EV) for entry and descent, and the Air Vehicle (AV) to fly in Titan's atmosphere. Using an Earth-Jupiter gravity assist trajectory delivers the spacecraft to Titan in 7.5 years, after which the AVIATR AV would operate for a 1-Earth-year nominal mission. We propose a novel 'gravity battery' climb-then-glide strategy to store energy for optimal use during telecommunications sessions. We would optimize our science by using the flexibility of the airplane platform, generating context data and stereo pairs by flying and banking the AV instead of using gimbaled cameras. AVIATR would climb up to 14 km altitude and descend down to 3.5 km altitude once per Earth day, allowing for repeated atmospheric structure and wind measurements all over the globe. An initial Team-X run at JPL priced the AVIATR mission at FY10 $715M based on the rules stipulated in the recent Discovery announcement of opportunity. Hence we find that a standalone Titan airplane mission can achieve important science building on Cassini's discoveries and can likely do so within a New Frontiers budget.

AB Western and guideline based diets were compared to determine if dietary improvements resulting from following dietary guidelines reduce acrylamide intake. Acrylamide forms in heat treated foods and is a human neurotoxin and animal carcinogen. Acrylamide intake from the Western diet was estimated with probabilistic techniques using teenage (13-19 years) National Health and Nutrition Examination Survey (NHANES) food consumption estimates combined with FDA data on the levels of acrylamide in a large number of foods. Guideline based diets were derived from NHANES data using linear programming techniques to comport to recommendations from the Dietary Guidelines for Americans, 2005. Whereas the guideline based diets were more properly balanced and rich in consumption of fruits, vegetables, and other dietary components than the Western diets, acrylamide intake (mean SE) was significantly greater (P < 0.001) from consumption of the guideline based diets (0.508 +/- 0.003 mu g/kg/day) than from consumption of the Western diets (0.441 +/- 0.003 mu g/kg/day). Guideline based diets contained less acrylamide contributed by French fries and potato chips than Western diets. Overall acrylamide intake, however, was higher in guideline based diets as a result of more frequent breakfast cereal intake. This is believed to be the first example of a risk assessment that combines probabilistic techniques with linear programming and results demonstrate that linear programming techniques can be used to model specific diets for the assessment of toxicological and nutritional dietary components.

ID RESEARCH-AND-DEVELOPMENT; DEVELOPMENT-PROJECTS; MODEL; INVESTMENT
AB We consider two opponents that compete in developing asymmetric technologies where each party's technology is aimed at damaging (or neutralizing) the other's technology. The situation we consider is different than the classical problem of commercial R&D races in two ways: First, while in commercial R&D races the competitors compete over the control of market share, in our case the competition is about the effectiveness of technologies with respect to certain capabilities. Second, in contrast with the "winner-takes-all" assumption that characterizes much of the literature on this field in the commercial world, we assume that the party that wins the race gains a temporary advantage that expires when the other party develops a superior technology. We formulate a variety of models that apply to a one-sided situation, where one of the two parties has to determine how much to invest in developing a technology to counter another technology employed by the other party. The decision problems are expressed as (convex) nonlinear optimization problems. We present an application that provides some operational insights regarding optimal resource allocation. We also consider a two-sided situation and develop a Nash equilibrium solution that sets investment values, so that both parties have no incentive to change their investments.

AB A prototype modular ultrawideband wavelength-scaled array of flared notches has been designed, built, measured and validated with full-wave modeling tools. Wavelength-scaled arrays operate over ultrawide bandwidths with significantly-reduced element counts, maintaining a relatively-constant beam size by utilizing phased-array radiators of different size. The prototype phased array presented here is designed to operate over an 8: 1 bandwidth (1-8 GHz), demonstrating a 12-degree beam capacity at 2 GHz, 4 GHz, and 8 GHz. The architecture achieves a reduction in element count by a factor of 6.4-only 160 elements per polarization as compared to a conventional 1024-element phased array of the same aperture size-at the cost of reduced beamwidth capacity in the higher frequency range. Performance metrics (active VSWR and radiation characteristics) of the wavelength-scaled array are measured and validated against full-wave simulations. The technology is presented as a viable alternative to more expensive conventional ultrawideband arrays with dense uniform element layouts.

SO JOURNAL OF THE ACOUSTICAL SOCIETY OF AMERICA
LA English
DT Article
ID OSCILLATORS; ENERGY; WAVES
AB The effect of dissipation on the real part of the admittance of an elastic half-space is typically thought to be unimportant if the loss factor zeta of the elastic medium is small. However, dissipation induces losses in the near field of the source and, provided the size of the source is small enough, this phenomenon can be more important than elastic wave radiation. Such losses give rise to a fundamental limit in the quality factor of an oscillator attached to a substrate. Near field losses associated with strains in the elastic substrate can actually be larger than intrinsic losses in the oscillator itself if the internal friction of the substrate is larger than the internal friction of the oscillator. For a uniform stress applied to a disk of radius a, a monopole source, such phenomena become significant for k(L)a < zeta, while for higher order multipole sources of order l, near field losses are important for (k(L)a)(l+1) < zeta, a far less restrictive constraint.

ID SCATTERING; SURFACE
AB A spiral wave front source generates a pressure field that has a phase that depends linearly on the azimuthal angle at which it is measured. This differs from a point source that has a phase that is constant with direction. The spiral wave front source has been developed for use in navigation; however, very little work has been done to model this source in an ocean environment. To this end, the spiral wave front analogue of the acoustic point source is developed and is shown to be related to the point source through a simple transformation. This makes it possible to transform the point source solution in a particular ocean environment into the solution for a spiral source in the same environment. Applications of this transformation are presented for a spiral source near the ocean surface and seafloor as well as for the more general case of propagation in a horizontally stratified waveguide.

AB The one-dimensional Vlasov-Poisson system is considered and a particle method is developed to approximate solutions without compact support which tend to a fixed background of charge as vertical bar x vertical bar -> infinity. Such a system of equations can be used to model kinetic phenomena occurring in plasma physics. A localized particle method is constructed and implemented using the fact that solutions to the Vlasov-Poisson system propagate at finite speeds. Finally, the numerical method is utilized to ascertain information regarding the time asymptotics of the generated electrostatic field. (C) 2011 IMACS. Published by Elsevier B.V. All rights reserved.

AB The relative motion of stars and other celestial objects in very wide pairs, separated by distances of the order of 1 pc, is strongly influenced by the tidal gravitational potential of the Galaxy. The Coriolis component of the horizontal tidal force in the rotating reference frame tends to disrupt such marginally bound pairs. However, even extremely wide pairs of bodies can be bound over intervals of time comparable to the Hubble time, under appropriate initial conditions. Here we show that for arbitrary chosen initial coordinates of a pair of stars, there exists a volume of the space of initial velocity components where the orbits remain bound in the planar tidal field for longer than 10 Gyr, even though the initial separation is well outside the Jacobi radius. The boundary of this phase space of stable orbits is fractal, and the motion at the boundary conditions is clearly chaotic. We found that the pairs may remain confined for several Gyr, and then suddenly disintegrate due to a particularly close rendezvous. By reversing such long-term stable orbits, we find that entrapment of unrelated stars into wide pairs is possible, but should be quite rare. Careful analysis of precision astrometry surveys revealed that extremely wide pairs of stars are present in significant numbers in the Galaxy. These results are expected to help in discriminating the cases of genuine binarity and chance entrapment, and to make inroads in testing the limits of Newtonian gravitation.

AB Using an 850-nanometer-wavelength free-space optical (FSO) communications system of our own design, we acquired field data for the transmitted and received signals in fog at Point Loma, CA for a range of optical depths within the multiple-scattering regime. Statistical estimators for the atmospheric channel transfer function and the related coherency function were computed directly from the experimental data. We interpret the resulting channel transfer function estimates in terms of the physics of the atmospheric propagation channel and fog aerosol particle distributions. We investigate the behavior of the estimators using both real field-test data and simulated propagation data. We compare the field-data channel transfer function estimates against the outputs from a computationally-intensive radiative-transfer theory model-based approach, which we also developed previously for the FSO multiple-scattering atmospheric channel. Our results show that the data-driven channel transfer function estimates are in close agreement with the radiative transfer modeling, and provide comparable receiver signal detection performance improvements while being significantly less time and computationally-intensive.

AB We consider the weak turbulence of whistler waves in the in low-beta inner magnetosphere of the earth. Whistler waves, originating in the ionosphere, propagate radially outward and can trigger nonlinear induced scattering by thermal electrons provided the wave energy density is large enough. Nonlinear scattering can substantially change the direction of the wave vector of whistler waves and hence the direction of energy flux with only a small change in the frequency. A portion of whistler waves return to the ionosphere with a smaller perpendicular wave vector resulting in diminished linear damping and enhanced ability to pitch-angle scatter trapped electrons. In addition, a portion of the scattered wave packets can be reflected near the ionosphere back into the magnetosphere. Through multiple nonlinear scatterings and ionospheric reflections a long-lived wave cavity containing turbulent whistler waves can be formed with the appropriate properties to efficiently pitch-angle scatter trapped electrons. The primary consequence on the earth's radiation belts is to reduce the lifetime of the trapped electron population. (C) 2012 American Institute of Physics. [http://dx.doi.org/10.1063/1.3692092]

AB A rational response to an inconsistent set of propositions is to revise it in a minimal way to restore consistency. A more important psychological goal is usually to create an explanation that resolves the inconsistency. We report five studies showing that once individuals have done so, they find inconsistencies harder to detect. Experiment 1 established the effect when participants explained inconsistencies, and Experiment 2 eliminated the possibility that the effect was a result of demand characteristics. Experiments 3a and 3b replicated the result, and showed that it did not occur in control groups that evaluated (or justified) which events in the pairs of assertions were more surprising. Experiment 4 replicated the previous findings, but the participants carried out all the conditions acting as their own controls. In all five studies, control conditions established that participants were able to detect comparable inconsistencies. Their explanations led them to reinterpret the generalizations as holding by default, and so they were less likely to treat the pairs of assertions as inconsistent. Explanations can accordingly undo the devastating consequences of logical inconsistencies, but at the cost of a subsequent failure to detect them. (C) 2012 Elsevier B.V. All rights reserved.

AB The Chagos Archipelago was designated a no-take marine protected area (MPA) in 2010; it covers 550 000?km2, with more than 60 000?km2 shallow limestone platform and reefs. This has doubled the global cover of such MPAs. It contains 2550% of the Indian Ocean reef area remaining in excellent condition, as well as the world's largest contiguous undamaged reef area. It has suffered from warming episodes, but after the most severe mortality event of 1998, coral cover was restored after 10?years. Coral reef fishes are orders of magnitude more abundant than in other Indian Ocean locations, regardless of whether the latter are fished or protected. Coral diseases are extremely low, and no invasive marine species are known. Genetically, Chagos marine species are part of the Western Indian Ocean, and Chagos serves as a stepping-stone in the ocean. The no-take MPA extends to the 200?nm boundary, and. includes 86 unfished seamounts and 243 deep knolls as well as encompassing important pelagic species. On the larger islands, native plants, coconut crabs, bird and turtle colonies were largely destroyed in plantation times, but several smaller islands are in relatively undamaged state. There are now 10 important bird areas, coconut crab density is high and numbers of green and hawksbill turtles are recovering. Diego Garcia atoll contains a military facility; this atoll contains one Ramsar site and several strict nature reserves. Pollutant monitoring shows it to be the least polluted inhabited atoll in the world. Today, strict environmental regulations are enforced. Shoreline erosion is significant in many places. Its economic cost in the inhabited part of Diego Garcia is very high, but all islands are vulnerable. Chagos is ideally situated for several monitoring programmes, and use is increasingly being made of the archipelago for this purpose. Copyright (c) 2012 John Wiley & Sons, Ltd.

TI A DECADE OF COUNTERING BIOTERRORISM: INCREMENTAL PROGRESS, FUNDAMENTAL
FAILINGS
SO BIOSECURITY AND BIOTERRORISM-BIODEFENSE STRATEGY PRACTICE AND SCIENCE
LA English
DT Article
AB The fear and disruption caused by the 2001 anthrax attacks understandably led Americans to seek enhanced biodefenses. However, the path followed since those attacks has left the country inadequately prepared to face further risks from biological attacks. Why has security against these threats been only partially achieved? This article suggests that our responses over the past decade can be sorted into 4 levels in order of increasing difficulty. First, we rapidly appropriated funds, augmented personnel, and mandated reorganization of agencies. Though not easy to accomplish, these steps were easily conceptualized and, whatever their imperfections, could rather assuredly be achieved. A second level was more demanding, but also quite achievable. It involved the amplification of ongoing efforts. These efforts sometimes suffered as they scaled up, but, though they were qualified by delays and uncertainties, we can point to real achievements at this level. A third level was more difficult: It required evolving new strategies to deal with this largely unprecedented problem. In this regard, we have so far had only glimmers of possibility. At a fourth level, our performance and our prospects are worse still. At this level, our problems stem from resistances inherent in our country's cultural and political framework. This article identifies some of these problems and suggests, regrettably, that they are not likely to be resolved until change is catalyzed by further, and more dramatically traumatic, attacks or natural disasters. If this situational assessment is correct, what remedial strategies should we pursue? The article distinguishes 3 strategic approaches: an evolutionary one in which the U. S. continues advancing along its present path; a radical approach that attempts to address the fourth-level issues; and a third approach that prepares for punctuated evolution. This third approach accepts the improbability of level 4 change either by gradual evolution or by radical argument, but asserts that it is possible to lay the conceptual groundwork now for the radical changes that will be possible, even demanded, after a catastrophic incident. This approach, neglected at present, would be a valuable addition to our present efforts.

AB Spin-orbit coupling can be described in two approaches. The first method, known as the "MacDonald torque", is often combined with a convenient assumption that the quality factor Q is frequency-independent. This makes the method inconsistent, because derivation of the expression for the MacDonald torque tacitly fixes the rheology of the mantle by making Q scale as the inverse tidal frequency. Spin-orbit coupling can be treated also in an approach called "the Darwin torque". While this theory is general enough to accommodate an arbitrary frequency-dependence of Q, this advantage has not yet been fully exploited in the literature, where Q is often assumed constant or is set to scale as inverse tidal frequency, the latter assertion making the Darwin torque equivalent to a corrected version of the MacDonald torque. However neither a constant nor an inverse-frequency Q reflect the properties of realistic mantles and crusts, because the actual frequency-dependence is more complex. Hence it is necessary to enrich the theory of spin-orbit interaction with the right frequency-dependence. We accomplish this programme for the Darwin-torque-based model near resonances. We derive the frequency-dependence of the tidal torque from the first principles of solid-state mechanics, i.e., from the expression for the mantle's compliance in the time domain. We also explain that the tidal torque includes not only the customary, secular part, but also an oscillating part. We demonstrate that the lmpq term of the Darwin-Kaula expansion for the tidal torque smoothly passes zero, when the secondary traverses the lmpq resonance (e. g., the principal tidal torque smoothly goes through nil as the secondary crosses the synchronous orbit). Thus, we prepare a foundation for modeling entrapment of a despinning primary into a resonance with its secondary. The roles of the primary and secondary may be played, e. g., by Mercury and the Sun, correspondingly, or by an icy moon and a Jovian planet. We also offer a possible explanation for the "improper" frequency-dependence of the tidal dissipation rate in the Moon, discovered by LLR.

AB The wide-spread availability of ensembles of high-performance clocks has motivated interest in time-scale algorithms. There are many such algorithms in use today in applications ranging from scientific to commercial. Although these algorithms differ in key aspects and are sometimes tailored for specific applications and mixtures of clocks, they all share the goal of combining measured time differences between clocks to form a reference time scale that is more stable than any of the clocks in the ensemble. A new approach to forming time scales is presented here, the multiscale ensemble timescale (METS) algorithm. This approach is based on a multi-resolution analysis afforded by the discrete wavelet transform. The algorithm does not assume a specific parametric model for the clocks involved and hence is well-suited for an ensemble of highly disparate clocks. The approach is based on an appealing optimality criterion which yields a reference time scale that is more stable than the constituent clocks over all averaging intervals (scales). The METS algorithm is presented here in detail and is shown in a simulation study to compare favorably with a time-scale algorithm based on Kalman filtering.

AB Silicon nitride thin films were deposited on (100) Si wafers in an ultra-high vacuum system using a Si effusion cell and reactive nitrogen from a radio-frequency plasma source. The films were characterized using infrared transmission spectroscopy, infrared reflectance, Rutherford backscattering spectrometry, spectroscopic ellipsometry, specular x-ray reflectivity, wet etching in a buffered-oxide etch solution, and the electrical characterization of metal-insulator-semiconductor capacitors. High-quality, stoichiometric silicon nitride films with a refractive index of 2.05 at 632.8 nm are produced when the deposition temperature is 750 degrees C. Lower deposition temperatures produce nitrogen-rich silicon nitride films with lower refractive index, lower density, greater tendency toward oxidation in ambient air, faster etching in a buffered oxide etch solution, and greater electrical leakage. A deposition model involving thermal evolution of weakly-bonded excess N is proposed to explain our observations. (C) 2012 American Vacuum Society. [DOI: 10.1116/1.3675835]

AB The authors have investigated the growth and structural and electrical properties of homoepitaxial GaN layers and GaN/AlGaN heterostructures grown on free-standing, hydride vapor phase epitaxy grown, N-polar GaN: Fe substrates by rf-plasma molecular beam epitaxy. Secondary-ion mass spectroscopic analysis of unintentionally doped and Be-doped N-polar GaN layers indicate that oxygen is the dominant impurity in all layers and is largely insensitive to growth temperature in the range investigated (675 degrees C < T-S < 760 degrees C). Transmission electron microscopy (TEM) indicates that threading dislocations are generated at the regrowth interface in these samples; in contrast to homoepitaxial growth on Ga-polar GaN, and that the density of threading dislocations diminishes as the growth temperature increases. However, examination by TEM indicates that threading dislocations are not generated at the regrowth interface of samples subjected to pregrowth substrate surface cleaning by gallium deposition and desorption and subsequent growth of ultrathin (15 degrees) initial AlN layers. N-polar GaN/AlGaN heterostructures grown on Be-doped homoepitaxial N-polar GaN buffers exhibit low buffer leakage and Hall mobilities up to 1680 cm(2)/Vs at sheet densities of 1.3 x 10(13) cm(-2). High electron mobility transistors have been fabricated on these structures; drain current densities over 700 mA/mm and breakdown voltages as high as 70V have been measured.

AB Contactless measurements of water temperature are utilized in a number of sciences, such as oceanography, climatology, and biology. Previously reported Raman spectroscopy techniques exploited the changes in the shapes of water Raman bands. Interpretation of these changes is difficult since these bands are composed of multiple lines, each influenced not only by temperature but also by pressure and salinity. This paper presents a proof-of-principal demonstration of a contactless technique which determines water temperature from the ratio of Stokes and anti-Stokes intensities of the water 180 cm(-1) Raman band. This ratio is not sensitive to pressure and salinity, allowing reliable determination of water temperature. (C) 2012 American Institute of Physics. [http://dx.doi.org/10.1063/1.3685613]

AB The primary aim of the current study was to obtain information about the longitudinal clinical functioning of primary care patients who had received care from behavioral health consultants (BHCs) integrated into a large family medicine clinic. Global mental health functioning was measured with the 20-item self-report Behavioral Health Measure (BHM), which was completed by patients at all appointments with the BHC. The BHM was then mailed to 664 patients 1.5 to 3 years after receipt of intervention from BHCs in primary care, of which 70 (10.5%) were completed and returned (62.9% female; mean age 43.1 +/- 12.7 years; 48.6% Caucasian, 12.9% African American, 21.4% Hispanic/Latino, 2.9% Asian/Pacific Islander, 10.0% Other, 4.3% no response). Mixed effects modeling revealed that patients improved from their first to last BHC appointment, with gains being maintained an average of 2 years after intervention. Patterns of results remained significant even when accounting for the receipt of additional mental health treatment subsequent to BHC intervention. Findings suggest that clinical gains achieved by this subset of primary care patients that were associated with brief BHC intervention were maintained approximately 2 years after the final appointment.

AB A high-order accurate radiative transfer (RT) model developed by Fu and Liou has been implemented into the Navy Operational Global Atmospheric Prediction System (NOGAPS) to improve the energy budget and forecast skill. The Fu-Liou RT model is a four-stream algorithm (with a two-stream option) integrating over 6 shortwave bands and 12 longwave bands. The experimental 10-day forecasts and analyses from data assimilation cycles are compared with the operational output, which uses a two-stream RT model of three shortwave and five longwave bands, for both winter and summer periods. The verifications against observations of radiosonde and surface data show that the new RT model increases temperature accuracy in both forecasts and analyses by reducing mean bias and root-mean-square errors globally. In addition, the forecast errors also grow more slowly in time than those of the operational NOGAPS because of accumulated effects of more accurate cloud-radiation interactions. The impact of parameterized cloud effective radius in estimating liquid and ice water optical properties is also investigated through a sensitivity test by comparing with the cases using constant cloud effective radius to examine the temperature changes in response to cloud scattering and absorption. The parameterization approach is demonstrated to outperform that of constant radius by showing smaller errors and better matches to observations. This suggests the superiority of the new RT model relative to its operational counterpart, which does not use cloud effective radius. An effort has also been made to improve the computational efficiency of the new RT model for operational applications.

AB Changes in electron density near the surface of a metal gives rise to the largest part of its work function, but a small contribution arises from the penetration of electrons into the classically forbidden region and the dipole component which results. An analytic model of the dipole term is difficult for the image charge potential, but it is shown, first, that a slab plus triangular barrier (STB) potential has a straightforward solution and, second, that it fits well with a general "shape factor" method to find the transmission probability (and, from it, the current density). The shape factors for rectangular, triangular, quadratic, STB, and image charge potentials are compared: it is shown that, just as the STB potential is intermediate between the rectangular and triangular potentials, the image charge potential is intermediate between the triangular and quadratic potentials. The evaluation of parameters needed for a general thermal-field-photoemission equation is demonstrated. Finally, the STB model enables a shifted electron density representation that is useful to estimate the increasing dipole component to the work function and the corresponding decrease in current density for high fields. Modifications to treat semiconductors are briefly described. (C) 2012 American Institute of Physics. [http://dx.doi.org/10.1063/1.3692571]

AB Space charge effects reduce electron emission by altering the surface barrier via two effects: increasing the barrier height (Schottky factor) and width to electron emission by lowering the surface field and changing the magnitude of the dipole associated with electron density variation. A one-dimensional emission model using a transit time argument to account for charge in the anode-cathode (AK) gap and an analytical model of the dipole is used to approximate the effects of each factor on the current density. The transit time model is compared to the experimental data of Longo [J. Appl. Phys. 94, 6966 (2003)] for thermal emission. Changes in the dipole contribution are primarily associated with tunneling and therefore field emission. The transit time plus dipole modification is compared to the experimental data of Barbour et al. [Phys. Rev. 92, 45 (1953)] for field emission. The model's application to thermal-field, and photoemission in general is discussed, with the former corresponding to continuous current limit and the latter to a pulsed current limit of the model.

AB A tabletop apparatus permitting demonstrations and hands-on student exercises in the acoustic beamforming of linear arrays is described. The apparatus can be used to demonstrate how interference effects from two or more linearly arranged sources produce patterns of maxima and minima as described by theory. A transmitting array is attached to the top of a rotating table and a receiving transducer provides voltages to a signal processor. Students measure the angular speed of the rotating table and the voltages produced by the receiving transducer as a function of time. These data can be analyzed in a spreadsheet program and compared to theory. The angles at which signal maxima occur correspond well to theory and useful teaching discussions result from comparisons of signal maxima magnitudes. The spreadsheet analysis can also provide the students a graphical demonstration of l'Hocircumflexpital's rule. [DOI: 10.1121/1.3677242]

AB A limited domain, coastal ocean forecast system consisting of an unstructured grid model, a meteorological model, a regional ocean model, and a global tidal database is designed to be globally relocatable. For such a system to be viable, the predictability of coastal currents must be well understood with error sources clearly identified. To this end, the coastal forecast system is applied at the mouth of Chesapeake Bay in response to a Navy exercise. Two-day forecasts are produced for a 10-day period from 4 to 14 June 2010 and compared to real-time observations. Interplay between the temporal frequency of the regional model boundary forcing and the application of external tides to the coastal model impacts the tidal characteristics of the coastal current, even contributing a small phase error. Frequencies of at least 3 h are needed to resolve the tidal signal within the regional model; otherwise, externally applied tides from a database are needed to capture the tidal variability. Spatial resolution of the regional model (3 vs 1 km) does not impact skill of the current prediction. Tidal response of the system indicates excellent representation of the dominant M-2 tide for water level and currents. Diurnal tides, especially K-1, are amplified unrealistically with the application of coarse 27-km winds. Higher-resolution winds reduce current forecast error with the exception of wind originating from the SSW, SSE, and E. These winds run shore parallel and are subject to strong interaction with the shoreline that is poorly represented even by the 3-km wind fields. The vertical distribution of currents is also well predicted by the coastal model. Spatial and temporal resolution of the wind forcing including areas close to the shoreline is the most critical component for accurate current forecasts. Additionally, it is demonstrated that wind resolution plays a large role in establishing realistic thermal and density structures in upwelling prone regions.

ID ORTHOGONAL FUNCTIONS
AB The nonorthogonality of algebraic polynomials of field coordinates traditionally used to model field-dependent corrections to astrometric measurements, gives rise to subtle adverse effects. In particular, certain field-dependent perturbations in the observational data propagate into the adjusted coefficients with considerable magnification. We explain how the worst perturbation, resulting in the largest solution error, can be computed for a given nonorthogonal distortion model. An algebraic distortion model of full rank can be converted into a fully orthonormal model based on the Zernike polynomials for a circular field of view, or a basis of functions can be constructed from the original model by a variant of the Gram-Schmidt orthogonalization process for a rectangular field of view. The relative significance of orthonormal distortion terms is assessed simply by the numerical values of the corresponding coefficients. Orthonormal distortion models are easily extendable when the distribution of residuals indicate the presence of higher-order terms.

TI Fetal loss in symptomatic first-trimester pregnancy with documented yolk
sac intrauterine pregnancy
SO AMERICAN JOURNAL OF EMERGENCY MEDICINE

DT Article
ID THREATENED-ABORTION; FAILURE; SIGN
AB Background: The possibility of spontaneous miscarriage is a common concern among pregnant women in the emergency department (ED).
Objective: This study sought to determine fetal outcomes for women following ED evaluation for first-trimester abdominopelvic pain or vaginal bleeding who had an intrauterine pregnancy (IUP) on ultrasound before a visible fetal pole ("yolk sac IUP").
Methods: A retrospective chart review of consecutive ED charts from December 2005 to September 2006 identified patients with a yolk sac IUP. Demographic data, obstetric/gynecologic history, and presenting symptoms were obtained. Outcomes were determined via computerized records. Fetal loss was diagnosed by falling beta-human chorionic gonadotropin or pathology specimen. Live birth was diagnosed by viable fetus at 20-week ultrasound or delivery.
Results: A total of 131 patients were enrolled in this study. Of these, 14 were lost to follow-up (12%), leaving 117 patient encounters. Of the 117 women, 82 carried their pregnancies to at least 20-week gestation. Thirty-five patients miscarried. Fetal loss rate by chief complaint were as follows: 8 of 46 patients presenting with pain only, 14 of 34 presenting with vaginal bleeding only, and 13 of 37 with both vaginal bleeding and pain.
Conclusion: Seventy percent of women diagnosed with a yolk sac IUP in the ED carried their pregnancy to at least 20 weeks. The remaining women (30%) experienced fetal loss. Vaginal bleeding (with or without pain) increased the rate of fetal loss compared with women with pain only. These data will assist the emergency physician in counseling women with symptomatic first-trimester pregnancies. Published by Elsevier Inc.

AB USING THE AMAZING ATMOSPHERE TO FOSTER STUDENT LEARNING AND INTEREST IN METEOROLOGY
To engage students in active learning, the Oceanography Department at the United States Naval Academy developed a new, not-for-course-credit training activity for its students, the Severe Weather In-Field Training (SWIFT). In SWIFT, 10 students and 2 faculty members traveled to the Great Plains and met with operational and research meteorologists, led daily weather discussions, made daily convective forecasts, and verified their convective forecasts by observing severe storms. Participation was solicited from sophomore- and junior-level students. SWIFT built on similar activities developed by other universities with its particular emphasis on assessing student learning and broadening awareness of both Department of Defense and civilian career opportunities in meteorology. Assessment outcomes from SWIFT indicate that students deepened their understanding of severe weather processes, were equipped to use observational and modeling data in real time, applied course content to real-world situations, became active participants in science inquiry, were introduced to a variety of meteorology career options, and increased their interest in pursuing a science-related career.

AB This paper describes the design and flight implementation of time-optimal attitude maneuvers performed onboard NASA's Transition Region and Corona! Explorer spacecraft. Minimum-time reorientation maneuvers have obvious applications for improving the agility of spacecraft systems, yet this type of capability has never before been demonstrated in flight due to the lack of reliable algorithms for generating practical optimal control solutions suitable for flight implementation. Constrained time-optimal maneuvering of a rigid body is studied first, in order to demonstrate the potential for enhancing the performance of the Transition Region and Coronal Explorer spacecraft. Issues related to the experimental flight implementation of time-optimal maneuvers onboard Transition Region and Coronal Explorer are discussed. A description of an optimal control problem that includes practical constraints such as the nonlinear reaction wheel torque-momentum envelope and rate gyro saturation limits is given. The problem is solved using the pseudospectral optimal control theory implemented in the MATLAB (R) software DIDO. Flight results, presented for a typical large-angle time-optimal reorientation maneuver, show that the maneuvers can be implemented without any modification of the existing spacecraft attitude control system. A clear improvement in spacecraft maneuver performance as compared with conventional eigenaxis maneuvering is demonstrated.

AB Two objectives dominate consideration of control moment gyroscopes for spacecraft maneuvers: high torque (equivalently momentum) and singularity-free operations. This paper adds to the significant body of research toward these two goals using a minimal three-control-moment-gyroscope array to provide significant singularity-free momentum performance increase spherically (in all directions) by modification of control-moment-gyroscope skew angles, compared with the ubiquitous pyramid geometry skewed at 54.73 deg. Spherical 1H (one control moment gyroscope's worth momentum) singularity-free momentum is established with bidirectional 1H and 2H in the third direction in a baseline configuration. Next, momentum space reshaping is shown via mixed skew angles permitting orientation of maximum singularity-free angular momentum into the desired direction of maneuver (yaw in this study). Finally, a decoupled gimbal angle calculation technique is shown to avoid loss of attitude control associated with singular matrix inversion. This technique permits 3H (maximal) yaw maneuvers without loss of attitude control despite passing through singularity. These claims are demonstrated analytically, then heuristically, and finally validated experimentally.

AB Periodic arrays of plasmonic nanopillars have been shown to provide large, uniform surface-enhanced Raman scattering (SERS) enhancements. We show that these enhancements are the result of the combined impact of localized and propagating surface plasmon modes within the plasmonic architecture. Here, arrays of periodically arranged silicon nanopillars of varying sizes and interpillar gaps were fabricated to enable the exploration of the SERS response from two different structures; one featuring only localized surface plasmon (LSP) modes and the other featuring LSP and propagating (PSP) modes. It is shown that the LSP modes determine the optimal architecture, and thereby determine the optimum diameter for the structures at a given incident. However, the increase in the SERS enhancement factor for a system in which LSP and PSP cooperatively interact was measured to be over an order of magnitude higher and the peak in the diameter dependence was significantly broadened, thus, such structures not only provide larger enhancement factors but are also more forgiving of lithographic variations.

AB Introduction: The true incidences of genitourinary conditions in the modern era are not completely known. We sought to determine the incidence of genitourinary abnormalities in a group of asymptomatic adult patients undergoing axial imaging with virtual colonoscopy. Methods: We performed a post-hoc analysis of imaging results from a prospective, IRB-approved study that randomized patients to screening "virtual" CT colonography (CTC) followed by standard endoscopic colonoscopy. CTC scans were reviewed separately by an independent radiologist and a urologist for genitourinary abnormalities. Genitourinary abnormalities were characterized as of minor, moderate, or major clinical significance. Identified nephroliths were categorized by location, laterality, size, and number. Student's t-tests and Fisher's exact-tests were used for continuous and categorical variables as appropriate. Results: Of 490 patients undergoing CTC and eligible for analysis, no genitourinary abnormalities were found in 294 (60%), minor genitourinary abnormalities were found in 100 (20.4%), moderate genitourinary abnormalities were found in 86 (17.6%), and major genitourinary abnormalities were found in 10 (2%). Renal cysts (n = 60, 12%) were the most common minor urologic findings. Moderate and major genitourinary findings of nephrolithiasis, adrenal adenomas, and renal masses were noted in 13.9%, 3%, and 2% of the population, respectively. The largest stone was 1.2 cm, and the smallest was 1 mm; while 59% had stones < 3mm, 20% between 3 mm and 5 mm, 18% between 5 mm and 10 mm, and 3% > 10 mm in size. Unilateral stones were found in 85%, while bilateral were found in 15%, and the average number of stones was 2, (range 1 - 16). Age and male sex were significantly associated with moderate or major genitourinary findings p = 0.04 and p = 0.05, respectively. Conclusions: CT colonography in an asymptomatic screening population helped to identify nephrolithiasis in 13.9%. Moderate and major urologic abnormalities were found in 20% of the cohort. Risk factors included male sex and older age.

ID CARBON; COST
AB The transportation industry accounts for one quarter of global energy use and has by far the largest share of global oil consumption. It used 51.5% of the oil worldwide in 2003. Mobility projections show that it is expected to triple by 2050 with associated energy use. Considerable achievements recently have been obtained in the development of powder and powder-processed metallic alloys, metal matrix composites, intermetallics, and carbon fiber composites. These achievements have resulted in their introduction to the transportation industry in a wide variety of transportation components with significant impact on energy efficiency. A significant number of nano, nanostructured, and nanohybrid materials systems have been deployed. Others, some of them incorporating carbon nanotubes and graphene, are under research and development and exhibit considerable potential. Airplane redesign using a materials and functional systems integration approach was used resulting in considerable system improvements and energy efficiency. It is expected that this materials and functional systems integration soon will be adopted in the design and manufacture of other advanced aircrafts and extended to the automotive industry and then to the marine transportation industry. The opportunities for the development and application of new powder materials in the transportation industry are extensive, with considerable potential to impact energy utilization. However, significant challenges need to be overcome in several critical areas.

TI Divergence-Free Spatial Velocity Flow Field Interpolator for Improving
Measurements from ADCP-Equipped Small Unmanned Underwater Vehicles
SO JOURNAL OF ATMOSPHERIC AND OCEANIC TECHNOLOGY

ID DOPPLER CURRENT PROFILER; VESSEL MEASUREMENTS; PRACTICAL ASPECTS;
QUANTIFICATION
AB Applying a two-dimensional (2D) divergence-free (DF) interpolation to a one-person deployable unmanned underwater vehicle's (UUV) noisy moving-vessel acoustic Doppler current profiler (MV-ADCP) measurements improves the results and increases the utility of the UUV in tidal environments. For a 3.5-h MV-ACDP simulation that spatially and temporally varies with the M-2 tide, the 2D DF-estimated velocity magnitude and orientation improves by approximately 85%. Next the 2D DF method was applied to velocity data obtained from two UUVs that repeatedly performed seven 1-h survey tracks in Bear Cut Inlet, Miami, Florida. The DF method provides a more realistic and consistent representation of the ADCP measured flow field, improving magnitude and orientation estimates by approximately 25%. The improvement increases for lower flow velocities, when the ADCP measurements have low environmental signal-to-noise ratio. However, near slack tide when flow reversal occurs, the DF estimates are invalid because the flows are not steady state within the survey circuit.

AB Atrial fibrillation induced by electroconvulsive therapy (ECT) is rare, with only 3 reported cases. None of those cases involved either young healthy patients or right unilateral ECT. We report a 46-year-old healthy male observed to be in atrial fibrillation immediately after electrical induction of the 25th administration of right unilateral ECT. Diltiazem was administered, and he spontaneously cardioverted. After a negative cardiology workup, he safely resumed ECT. Atrial fibrillation was most likely triggered by autonomic imbalance due to the combination of electrical induction, seizure, and medication.

DE Open fracture; irrigation; debridement; wound contamination
ID PRESSURE PULSATILE LAVAGE; WOUND IRRIGATION; TAP WATER; IN-VITRO;

AB BACKGROUND: Treatment of open fractures demands rapid intervention consisting of intravenous antibiotics, aggressive debridement, fracture immobilization, and soft tissue management including additional debridements and soft tissue coverage. Despite this approach, infection, particularly osteomyelitis, after open fracture continues to be a source of significant morbidity. Recent literature has provided several studies that performed clinical trials in superficial wounds. These investigations compared sterile solutions with tap water for wound decontamination. The results suggest that tap water washouts are cost-effective for these specific wounds.
MATERIAL: An established protocol using sterile porcine hind limb tibias, as reported by Bhandari et al., was applied with modification. There were then 15 specimens and 5 controls (no irrigation) for each condition. The conditions were potable water and sterile water. A representative bacterium of gram-positive, Staphylococcus aureus, or gram-negative, Escherichia coli, acted as the contaminant. Sectioned, sterile porcine hind limb tibias were inoculated with 1 mL of a known concentration (1 x 10(10)) of bacterium and incubated. Each specimen was then irrigated, with bulb irrigation at a standardized distance of 15 cm, with 500 mL of irrigation. The specimen, along with 0.5 mL of wash (irrigant collected after it was placed over the specimen), was placed in 5 mL of Brain Heart Infusion broth. All specimens were incubated in this broth at 37 degrees C for 2 hours. At 2 hours, a 100-mu L supernatant was plated on blood agar plates and incubated for 24 hours. Colony counts for each specimen and controls were then performed.
RESULTS: The number of colony forming units (CFUs) for each type of bacterium was different. The average CFUs from bone samples contaminated with E. coli was 5.18 x 10(8) after irrigation with sterile water and 6.24 x 10(8) after irrigation with tap water. The average CFUs from bone samples contaminated with S. aureus was 18 x 10(6) after irrigation with sterile water and 12 x 10(6) after irrigation with tap water. The average CFUs from the irrigation samples from E. coli contamination treated with sterile water was 1.3 x 10(6) and the CFUs from E. coli contamination treated with tap water was 2.2 x 10(6). The average CFUs from the irrigation samples from S. aureus contamination treated with sterile water was 1.57 x 10(6) and the CFUs from S. aureus contamination treated with tap water was 1.56 x 10(6).
CONCLUSION: There was no significant difference between the CFUs for the sterile and potable water (p = 0.201) for each bacterium (p = 0.871). (J Trauma. 2012; 72: 733-736. Copyright (C) 2012 by Lippincott Williams & Wilkins)

DE Ballast Tank Coatings Assessments; Automated Inspection Systems;
Corrosion Detection and Assessment; Tank Monitoring Systems; Insertable
Stalk Inspection System
AB Since the mid-1990's, the Naval Research Laboratory (NRL) has explored the use of Corrosion Sensor-based Tank Monitoring Systems and the Insertable Stalk Inspection System (ISIS) as a means to reduce requirements for manned entry into tanks and voids during their inspections. These systems provide a means for providing information on the condition of a tank or void while eliminating requirements for gas freeing, cleaning, and preparing the tanks for manual inspection.
In 2010, the U.S. Navy's Corrosion Control Assessment and Maintenance Manual (CCAMM) was modified to afford the use of the Corrosion Sensor-based Tank Monitoring Systems, and for increased use of ISIS as a means of assessing the condition of tanks and voids on U.S. Navy ships. The Corrosion Sensor-based Tank Monitoring Systems afford a means to determine if a tank is actively corroding that does not require entering or opening the tank. ISIS provides a means to perform a visual inspection of a tank or void without requirements to certify the tank safe for human entry or for cleaning and preparing the tank for manned inspection. Combined, these systems provide a means for monitoring and documenting tank and void condition without requirements for human entry. This results in significant savings as the cost to prepare a tank for human entry and inspection are not incurred until the tank or void condition drives this action.

AB Objective: To evaluate the safety and efficacy of a new therapeutic agent, EPI-743, in Leber hereditary optic neuropathy (LHON) using standard clinical, anatomic, and functional visual outcome measures.
Design: Open-label clinical trial.
Setting: University medical center.
Patients: Five patients with genetically confirmed LHON with acute loss of vision were consecutively enrolled and treated with the experimental therapeutic agent EPI-743 within 90 days of conversion.
Intervention: During the course of the study, 5 consecutive patients received EPI-743, by mouth, 3 times daily (100-400 mg per dose).
Main Outcome Measures: Treatment effect was assessed by serial measurements of anatomic and functional visual indices over 6 to 18 months, including Snellen visual acuity, retinal nerve fiber layer thickness measured by optical coherence tomography, Humphrey visual fields (mean decibels and area with 1-log unit depression), and color vision. Treatment effect in this clinical proof of principle study was assessed by comparison of the prospective open-label treatment group with historical controls.
Results: Of 5 subjects treated with EPI-743, 4 demonstrated arrest of disease progression and reversal of visual loss. Two patients exhibited a total recovery of visual acuity. No drug-related adverse events were recorded.
Conclusions: In a small open-label trial, EPI-743 arrested disease progression and reversed vision loss in all but 1 of the 5 consecutively treated patients with LHON. Given the known natural history of acute and rapid progression of LHON resulting in chronic and persistent bilateral blindness, these data suggest that the previously described irreversible priming to retinal ganglion cell loss may be reversed.

AB Objective: To report the accuracy of intraocular lens (IOL) power calculations and the early refractive status in pseudophakic eyes of infants in the Infant Aphakia Treatment Study.
Methods: Eyes randomized to receive primary IOL implantation were targeted for a postoperative refraction of +8.0 diopters (D) for infants 28 to 48 days old at surgery and +6.0 D for those 49 days or older to younger than 7 months at surgery using the Holladay 1 formula. Refraction 1 month after surgery was converted to spherical equivalent, and prediction error (PE; defined as the calculated refraction minus the actual refraction) and absolute PE were calculated. Baseline eye and surgery characteristics and A-scan quality were analyzed to compare their effect on PE.
Main Outcome Measures: Prediction error.
Results: Fifty-six eyes underwent primary IOL implantation; 7 were excluded for lack of postoperative refraction (n=5) or incorrect technique in refraction (n=1) or biometry (n=1). Overall mean (SD) absolute PE was 1.8 (1.3) D and mean (SD) PE was +1.0(2.0) D. Absolute PE was less than 1 D in 41% of eyes but greater than 2 D in 41% of eyes. Mean IOL power implanted was 29.9D(range, 11.5-40.0 D); most eyes (88%) implanted with an IOL of 30.0 D or greater had less postoperative hyperopia than planned. Multivariate analysis revealed that only short axial length (<18 mm) was significant for higher PE.
Conclusions: Short axial length correlates with higher PE after IOL placement in infants. Less hyperopia than anticipated occurs with axial lengths of less than 18 mm or high-power IOLs.
Application to Clinical Practice: Quality A-scans are essential and higher PE is common, with a tendency for less hyperopia than expected.

TI Madden-Julian Oscillation (MJO) Modulation of Atmospheric Circulation
and Chilean Winter Precipitation
SO JOURNAL OF CLIMATE
LA English

ID RAINFALL VARIABILITY; ANDES; PREDICTION; SCALE; ENSO
AB The leading intraseasonal mode of tropical atmospheric variability, the Madden-Julian oscillation (MJO), has been shown to modulate precipitation and circulation on a global and regional scale. Winter precipitation in Chile has been connected to a variety of synoptic-scale forcing mechanisms. This study explored the links between the two, first examining the intraseasonal variability of Chilean precipitation from surface gauges and the Tropical Rainfall Measuring Mission (TRMM) and then examining the variability of synoptic-scale circulation.
Composites of precipitation, precipitation intensity, and lower-, middle-, and upper-tropospheric circulation were created using the Real-Time Multivariate MJO index, which divides the MJO into eight longitudinally based phases. Precipitation was found to vary across MJO phases, with positive precipitation anomalies in central and south-central Chile (30 degrees-45 degrees S) for MJO phases 8, 1, and 2, and negative anomalies in phases 3-7. Circulation was also found to vary across phase, in good agreement with precipitation: low geopotential height and negative omega (corresponding to upward vertical motion) anomalies were found over and upstream of Chile during the rainier phases, and the anomalies reversed during the drier phases. Surface pressure and middle- and upper-tropospheric geopotential height anomalies showed a classic equivalent barotropic wave train, indicating a teleconnection response to deep convective activity in the Maritime Continent in agreement with numerous earlier observational, modeling, and theoretical studies.

TI Intraseasonal Predictability of Siberian High and East Asian Winter
Monsoon and Its Interdecadal Variability
SO JOURNAL OF CLIMATE
LA English
DT Article
ID ARCTIC-OSCILLATION; CLIMATE; TEMPERATURE; REANALYSIS; PREDICTION;
BLOCKING
AB Current skill in the seasonal prediction of the Asian monsoon falls rapidly north of 40 degrees N, where the Siberian high (SH) is a prominent manifestation of the East Asian winter monsoon (EAWM). Variations in the SH are closely related to winter weather over a large latitudinal span from northern Asia to the equator. Here it is shown that during the three recent decades the SH had an intraseasonal variation that tended to be seasonally synchronized, which produced an out-of-phase relationship between November and December/January. This implies a special intraseasonal predictability that did not exist in the two previous decades. If this relationship continues, the EAWM will be the only known major circulation system whose intensity can be predicted to reverse from the previous month. It is hypothesized that this predictability is related to the reduced frequency of blocking events during the positive phase of the Arctic Oscillation (AO). While this suggests the predictability may diminish if the AO phase is reversed, it may become more prevalent in the future if the prediction of more frequent positive AO-like patterns in a warming world forced by greenhouse gases is borne out.

TI The Ecuadorian Army: Neglecting a Porous Border While Policing the

SO LATIN AMERICAN POLITICS AND SOCIETY
LA English
DT Article
ID LATIN-AMERICA; MILITARY
AB This article challenges two prominent explanations for military behavior: militaries, like other bureaucracies, will seek to maximize their budgets; and in the interest of maintaining professionalism, militaries will perform sovereignty missionsexternal defense and counterinsurgencymore intensively than policing functions. Running counter to these expectations, since 2000, Ecuador's army has neglected its professional, lucrative mission of northern border defense, instead focusing on police work. The analysis applies organization theory to argue that the army's minimal border defense efforts have been a way to maintain predictability for patrols on the ground, the part of the army that most directly performs the army's core function of security. Specifically, the article traces how a contradiction has emerged in the army's border mission. The contradiction has meant anything but predictability for the work of troops patrolling the border, compromising the mission.

AB Purpose: We recently demonstrated that diabetes mellitus was an independent risk factor for local recurrence (LR) for patients undergoing resection of non-small cell lung cancer (NSCLC). This investigation was performed to confirm or refute this finding in a different patient cohort.
Materials and methods: Patients were eligible if they did not have a second primary cancer within 5 years of the original diagnosis, had at least 3-month follow-up, and did not receive radiotherapy. There were 373 and 168 patients in the original (P1) and confirmatory (P2) cohorts, respectively, with 66 and 30 patients with diabetes.
Results: The median follow-up was 33 months (range, 3-98 months). Diabetes was an independent risk factor for LR in a Cox model in both the P2 (p = 0.05, hazard ratio [HR] 2.15) and P1 ( p = 0.008, HR 1.90) cohorts, separately from BMI, glucose control, and the presence of the metabolic syndrome. The rates of LR in the patients with diabetes after combining the cohorts at 2, 3, and 5 years were 23%, 33%, and 56%, respectively; these rates were 15%, 19%, and 26% in non-diabetics. In multivariate Cox regression and competing risk analysis of the combined cohorts, the HRs for LR in patients with diabetes exceeded those of more established risk factors for LR including a 1-cm increase in tumor size and lymphovascular invasion.
Conclusions: Diabetes was confirmed to be an independent predictor of the risk of LR following resection of NSCLC. (C) 2011 Elsevier Ireland Ltd. All rights reserved.

The numerical wave model WAM is employed on a high spatial resolution mode and in two different versions, one of which incorporates information for sea surface currents. Altimeter data obtained from all available satellite missions over the area are also utilized. The data sets are analyzed both by conventional statistical measures as well as by advanced techniques provided by a relatively new branch of mathematics, information geometry, in the framework of which the data under study and the distributions that they form are treated as elements of non Euclidean spaces. In this framework, novel ideas for the estimation of the deviations between the observed and modeled values are proposed.

SO MILITARY MEDICINE
LA English
DT Article
AB The purpose of this article is to report on the evaluation of vague abdominal pain and anemia in the deployed military environment resulting in the diagnosis of a giant gastric ulcer. This patient's abdominal pain was initially thought to be attributable to a lower digestive tract process and her anemia was insidious in onset but progressive. A computed tomography examination was obtained. Circumferential gastric wall thickening, more prominent posteriorly with ulceration, adjacent inflammation, and perigastric lymphadenopathy suspicious for a malignancy or a giant gastric ulcer was identified. Referral and medical evacuation to a tertiary care facility out of the deployed setting resulted in an endoscopy showing a giant gastric ulcer with no evidence of malignancy. Prompt evaluation of the patient with the most expeditious radiologic imaging modality available at hand, rather than delayed sequential evaluation, revealed an uncommon finding and conceivably saved this patient's life. Close cooperation among appropriate specialists in the deployed setting resulted in an optimal outcome in a suboptimal environment.

TI Unilateral Mydriasis Potentially Associated With Contact With a
Supplement Powder Mix
SO MILITARY MEDICINE
LA English
DT Article
AB Introduction: Dietary supplement use is common in military populations. Presented is a case of unilateral mydriasis from contact with a supplement mix. Standardized approach to mydriasis is fundamental for diagnosis. Case: A 20-year-old active duty Marine presented to the Emergency Department for evaluation of an enlarged pupil. She had no visual deficits or symptoms otherwise. She had been consuming increased amounts of energy drinks including a supplement powder mix and recalled rubbing her eye while pouring the mix that morning. Her exam demonstrated an asymmetric, nonreactive right pupil both directly and consensually with normal left pupil findings. Exam was otherwise unremarkable. Following unresponsiveness to pilocarpine challenges, pharmacological dilation was diagnosed potentially, secondary to supplement contact without absolute causative effect established. Two days afterward, her exam was normal. Discussion: Several supplement mixes contain compounds with stimulant activity mimicking medications used for pupil dilation. Unilateral mydriasis from contact with anticholingeric substances has been reported, specifically Angel's Trumpet, ipratropium, and moonflower, but there have been no reports with supplement mix-induced dilation. Conclusion: Dietary supplement use in the military is an overwhelming phenomenon. This unique presentation of pharmacological mydriasis reinforces the importance of supplement histories in our military populations for various health presentations.

AB Rickettsia parkeri, a spotted fever group (SFG) rickettsia recently found to be pathogenic to humans, causes an eschar-associated febrile illness. The R. parkeri rickettsiosis, Tidewater spotted fever, has been misdiagnosed as Rocky Mountain spotted fever due to serologic cross reactivity and the lack of specific diagnostic methods. Candidatus Rickettsia andeanae, also a SFG rickettsia, is a recently described agent of unknown pathogenicity originally identified in ticks collected from domestic animals during a fever outbreak investigation in northern Peru. Among 37 Amblyomma maculatum (collected from humans (n = 35) and questing (n = 2)) obtained from the southern United States during 2000-2009, nine and four A. maculatum nucleic acid preparations were found positive for R. parkeri and Candidatus R. andeanae, respectively, by newly developed genus-and species-specific quantitative real-time polymerase chain reaction assays. In addition Rickettsia felis was found in two A. maculatum nucleic acid preparations.

AB To determine whether hepatitis E virus (HEV) is a cause of hepatitis among HIV-infected persons, we evaluated 1985-2009 data for US military beneficiaries. Evidence of acute or prior HEV infection was detected for 7 (4%) and 5 (3%) of 194 HIV-infected persons, respectively. HEV might be a cause of acute hepatitis among HIV-infected persons.

TI Rectal Cultures Before Transrectal Ultrasound-guided Prostate Biopsy
Reduce Post-prostatic Biopsy Infection Rates
SO UROLOGY
LA English
DT Article
ID RESISTANT ESCHERICHIA-COLI; COMPLICATIONS; PROPHYLAXIS; PREVALENCE
AB OBJECTIVE To test our hypothesis that a targeted rectal screening protocol before transrectal ultrasound (TRUS)-guided biopsy would potentiate streamlined prophylaxis, thereby reducing postbiopsy infectious rates while minimizing unnecessary broad-spectrum antibiotic use. To this end, we instituted preprocedure rectal cultures in an effort to identify fluoroquinolone (FQ)-resistant flora using selective media to optimally direct targeted prophylactic antibiotic administration. The inexorably increasing prevalence of multidrug-resistant microorganisms, notably extended spectrum beta lactamase (ESBL)-producing and FQ-resistant Enterobacteriaceae has increased the post-TRUS prostatic biopsy infection rates, including life-threatening sepsis.
METHODS A total of 235 rectal swabs were obtained and plated directly onto MacConkey agar plates containing 10-mu g/mL ciprofloxacin. Following the screening procedure, antimicrobial susceptibility results were used to develop a customized antibiotic prophylaxis regimen to be administered before biopsy. Following the biopsy procedure, the patients were seen in follow-up within 7 days, and information was gathered on potential adverse effects, clinical appointments for infections, and potential antibiotics received.
RESULTS Thirty-two-patients (14%) had FQ-resistant isolates (most Escherichia coli), and 3 (1.3%) were ESBL-producing isolates. There were no infectious complications identified in this period, (compared with 3 septic complications among 103 biopsies in the 4 months preceding the study).
CONCLUSION Rectal cultures obtained before TRUS biopsy, using selective media to identify FQ-resistant Enterobacteriaceae, facilitate targeted antibiotic prophylaxis, and appear to be highly efficacious in reducing infectious complications. UROLOGY 79: 556-563, 2012. Published by Elsevier Inc.

AB We report on our second-year campaign of X-ray follow-up observations of unidentified Fermi Large Area Telescope (LAT) gamma-ray sources at high Galactic latitudes (vertical bar b vertical bar > 10 degrees) using the X-ray Imaging Spectrometer on board the Suzaku X-ray Observatory. In this second year of the project, seven new targets were selected from the First Fermi-LAT Catalog, and studied with 20-40 ks effective Suzaku exposures. We detected an X-ray point source coincident with the position of the recently discovered millisecond pulsar (MSP) PSR J2302+4442 within the 95% confidence error circle of 1FGL J2302.8+4443. The X-ray spectrum of the detected counterpart was well fit by a blackbody model with temperature of kT similar or equal to 0.3 keV, consistent with an origin of the observed X-ray photons from the surface of a rotating magnetized neutron star. For four other targets that were also recently identified with a normal pulsar (1FGL J0106.7+4853) and MSPs (1FGL J1312.6+0048, J1902.0-5110, and J2043.2+1709), only upper limits in the 0.5-10 keV band were obtained at the flux levels of similar or equal to 10(-14) erg cm(-2) s(-1). A weak X-ray source was found in the field of 1FGL J1739.4+8717, but its association with the variable gamma-ray emitter could not be confirmed with the available Suzaku data alone. For the remaining Fermi-LAT object 1FGL J1743.8-7620 no X-ray source was detected within the LAT 95% error ellipse. We briefly discuss the general properties of the observed high Galactic-latitude Fermi-LAT objects by comparing their multiwavelength properties with those of known blazars and MSPs.

AB With the prevalence of particle image velocimetry (PIV) as a quantitative tool for fluid mechanics diagnostics, its application for analyzing complicated multiphase flows has been steadily increasing over the last several decades. While the primary issue in using PIV for multiphase flows is in separating the information of the phases for independent analysis with a minimum of spurious "cross-talk," an equally crucial but often overlooked point is in the accurate quantitative measurement of the dispersed phase concentration. Accurate concentration measurement is important due to the fact that the dispersed phase is often heterogeneously distributed in both space and time, either due to a non-uniformity of the source of particulates (such as a spray nozzle or sediment boundary) or due to inertial migration of the particles even from originally homogeneous spatial distributions. In the current work, we examine the effects of light sheet profile distortion and attenuation by tracer seeding particles, as well as reflected light from local wall boundaries on the effective light sheet thickness. The effective thickness is critical for concentration measurements, as it dictates the dispersed phase detection volume. A direct calibration method is demonstrated to measure the effective light sheet thickness in a water/glass bead system, which shows that systematic bias errors on the order of 30% can result if the reflective bed condition is not accounted for, and the errors can be as high as 50% or more if a single-point measure of the sheet width is used.

AB The Hyperspectral Imager for the Coastal Ocean (HICO) instrument currently on board the International Space Station is a new sensor designed specifically for the studies of turbid coastal waters and large inland lakes and rivers. It covers the wavelength range between 0.4 and 0.9 mu m with a spectral resolution of 5.7 nm and a spatial resolution of approximately 90 m. The HICO sensor is not equipped with a second-order blocking filter in front of the focal plane array. As a result, the second-order light from the shorter visible spectral region falls onto the detectors covering the near-IR spectral region above 0.8 mu m. In order to have accurate radiometric calibration of the near-IR channels, the second-order light contribution needs to be removed. The water-leaving radiances of these near-IR channels over clear ocean waters are close to zero because of strong liquid water absorption above 0.8 mu m. Through analysis of HICO imaging data containing features of shallow underwater objects, such as coral reefs, we have developed an empirical technique to correct for the second-order light effects in near-IR channels. HICO data acquired over Midway Island in the Pacific Ocean and the Bahamas Banks in the Atlantic Ocean are used to demonstrate the effectiveness of the new technique.

AB Although focused ion beam (FIB) microscopy has been used successfully for milling patterns and creating ultra-thin electron and soft X-ray transparent sections of polymers and other soft materials, little has been documented regarding FIB-induced damage of these materials beyond qualitative evaluations of microstructure. In this study, we sought to identify steps in the FIB preparation process that can cause changes in chemical composition and bonding in soft materials. The impact of various parameters in the FIB-scanning electron microscope (SEM) sample preparation process, such as final milling voltage, temperature, ion beam overlap and mechanical stability of soft samples, was evaluated using two test-case materials systems: polyacrylamide, a low melting-point polymer, and Wyodak lignite coal, a refractory organic material. We evaluated changes in carbon bonding in the samples using X-ray absorption near-edge structure spectroscopy (XANES) at the carbon K edge and compared these samples with thin sections that had been prepared mechanically using ultramicrotomy. Minor chemical changes were induced in the coal samples during FIB-SEM preparation, and little effect was observed by changing ion-beam parameters. However, polyacrylamide was particularly sensitive to irradiation by the electron beam, which drastically altered the chemistry of the sample, with the primary damage occurring as an increase in the amount of aromatic carbon bonding (C=C). Changes in temperature, final milling voltage and beam overlap led to small improvements in the quality of the specimens. We outline a series of best practices for preparing electron and soft X-ray transparent samples, with respect to preserving chemical structure and mechanical stability of soft materials using the FIB.

AB Large-scale Rossby normal modes are studied for the Northern Hemisphere winters of 2005, 2006, 2008, and 2009 using global observational meteorological analyses spanning the 0-92-km altitude range. Spectral analysis of geopotential height fields shows pronounced peaks at westward-propagating zonal wavenumber 1 near the theoretical locations of the free Rossby waves at 25, 16, 10, and 5 days that, in some cases, have amplitudes significantly larger than the estimated background spectrum. Evidence is also found for a wavenumber-2 free mode near 4 days. A coherence analysis is used to extract the amplitude and phase of the waves, and to isolate those regions of the latitude/altitude plane where the signals are statistically significant. Although the spectral location, temporal evolution, and vertical structure of several of these waves are suggestive of the presence of Rossby normal modes, this study shows that in the real atmosphere the waves only occasionally have the global properties of classical normal modes. Moreover, no evidence is found that the amplitudes of these modes are enhanced during stratospheric sudden warmings.

AB A delivery person must leave the central location of the business, deliver packages at a number of addresses, and then return. Naturally, he/she wishes to reduce costs by finding the most efficient route. This motivates the following
Given a set of k distinct vertices S = {x(1), x(2), ..., x(k)} in a simple graph G, the closed k-stop-distance of set S is defined to be
d(k)(S) = min(theta is an element of P(S)) (d(theta(x(1)),theta(x(2))) + d(theta(x(2)),theta(x(3))) + ... + d(theta(x(k)),theta(x(1)))),
where P(S) is the set of all permutations of S. That is the same as saying that d(k) (S) is the length of a shortest closed walk through the vertices {x(1), ..., x(k)}.
The closed 2-stop distance is twice the standard distance between two vertices. We study the closed k-stop center and closed k-stop periphery of a graph, for k = 3.

AB Hexavalent chromium (Cr6+) emitted from welding poses serious health risks to workers exposed to welding fumes. In this study, tetramethylsilane (TMS) was added to shielding gas to control hazardous air pollutants produced during stainless steel welding. The silica precursor acted as an oxidation inhibitor when it decomposed in the high-temperature welding arc, limiting Cr6+ formation. Additionally, a film of amorphous SiO2 was deposited on fume particles to insulate them from oxidation. Experiments were conducted following the American Welding Society (AWS) method for fume generation and sampling in an AWS fume hood. The results showed that total shielding gas flow rate impacted the effectiveness of the TMS process. Increasing shielding gas flow rate led to increased reductions in Cr6+ concentration when TMS was used. When 4.2% of a 30-lpm shielding gas flow was used as TMS carrier gas, Cr6+ concentration in gas metal arc welding (GMAW) fumes was reduced to below the 2006 Occupational Safety and Health Administration standard (5 mu g m(-3)) and the efficiency was > 90%. The process also increased fume particle size from a mode size of 20 nm under baseline conditions to 180-300 nm when TMS was added in all shielding gas flow rates tested. SiO2 particles formed in the process scavenged nanosized fume particles through intercoagulation. Transmission electron microscopy imagery provided visual evidence of an amorphous film of SiO2 on some fume particles along with the presence of amorphous SiO2 agglomerates. These results demonstrate the ability of vapor phase silica precursors to increase welding fume particle size and minimize chromium oxidation, thereby preventing the formation of hexavalent chromium.

AB Geobacter sulfurreducens can acquire energy by coupling oxidation of acetate with extracellular electron transfer to an anode, forming an electrically conductive biofilm extending many cell lengths away from the anode surface. Owing to their conductivity, such biofilms may play important roles in emerging technologies referred to as bioelectrochemical systems (BES). In these systems, microbes are used to catalyze anode processes for which abiotic catalysts do not exist, such as wastewater treatment and energy generation from biomass by fuel cells. Two models describing the conductive nature of G. sulfurreducens biofilms grown on anodes (biofilm anodes) have recently been put forth; superexchange proposed by our group, recently published in Energy and Environmental Science, which invokes electron-transfer among a network of cytochromes, and metallic-like conductivity proposed by Malvankar et al., recently published in Nature Nanotechnology, which invokes intrinsic conductivity of certain secreted microbial filaments referred to as nanowires. Here, we respond to criticisms raised by Malvankar et al. in the preceding commentary concerning superexchange.

AB Recurrent pelvic organ prolapse occurs rarely after obliterative procedures. The optimal surgical approach for therapy is unknown. We describe a case of recurrent prolapse after LeFort colpocleisis. The patient presented with stage III prolapse through the lateral vaginal channel. At surgery, the prolapse was repaired using a modified repeat colpocleisis and repeat perineorrhaphy. Transvaginal revision via modified repeat colpocleisis should be considered for treatment of recurrent pelvic organ prolapse after LeFort colpocleisis.

AB We built and evaluated a predictive model for resuming after an interruption. Two different experiments were run. The first experiment showed that people used a transactive memory process, relying on another person to keep track of where they were after being interrupted while retelling a story. A memory for goals model was built using the ACT-R/E cognitive architecture that matched the cognitive and behavioral aspects of the experiment. In a second experiment, the memory for goals model was put on an embodied robot that listened to a story being told. When the human storyteller attempted to resume the story after an interruption, the robot used the memory for goals model to determine if the person had forgotten the last thing that was said. If the model predicted that the person was having trouble remembering the last thing said, the robot offered a suggestion on where to resume. Signal detection analyses showed that the model accurately predicted when the person needed help.

AB Condom use during last sexual contact is a survey measure that may be used to inform monitoring and evaluation indicators of recent condom use in populations at risk for HIV infection and other sexually transmitted infections, such as the uniformed services. The authors tested for differences in condom use measures that were fielded within separate Biological and Behavioral Surveillance Surveys conducted in the armed forces of two separate nations: the Dominican Republic and Belize. Both surveys included measures of condom use during last sexual contact with specified partners and both surveys included the Risk Behavior Assessment (RBA), which measures specific sexual acts and condom use frequency during a specified time period. In both samples, more than 40% of respondents who reported condom use during last sexual contact with a regular partner also reported engaging in unprotected sex when screened with the RBA. Furthermore, more than 60% of respondents who reported condom use during last sexual encounter with a commercial sex worker also reported engaging in unprotected sex when screened with the RBA. The results carry implications for monitoring and evaluation indicators of large-scale HIV prevention programs. The authors recommend that, when feasible, more in-depth instruments such as the RBA be considered to measure recent condom use in populations of uniformed services personnel.

AB Digital printing of interconnects for electronic devices requires processes capable of delivering controlled amounts of conductive inks in a fast and accurate way. Laser-induced forward transfer (LIFT) is an emerging technology that enables controlled printing of voxels of a wide range of inks with micrometer resolution. Its use with high solids content nanoparticle suspensions results in the deposition of voxels shaped as the impinging laser beam. This allows higher processing speeds, increasing the throughput of the technique. However, the optimum conditions for printing spot-like voxels have not been determined, yet. In this work, we perform a systematic study of the main experimental parameters, including laser pulse energy, laser beam dimensions, and gap distance, in order to understand the role that these parameters play in laser printing. Based on these results, we find that there is a narrow fluence range at distances close to the receiving substrate where spot-like voxels are deposited. We also provide a detailed discussion of the possible mechanisms that may lead to the observed features.
