Selective cleavage at internal lysine residues in protonated vs. metalated peptides

Abstract The proton, lithium, sodium, potassium and silver ion (Cat + ) adducts of the peptides GGKAA and SIKVAV are formed by electrospray ionization and the unimolecular chemistry of these ions is examined by low-energy collisionally activated dissociation (CAD) in a quadrupole ion trap mass spectrometer. Comparison of the fragmentation characteristics of [GGKAA+Cat] + and [SIKVAV+Cat] + to those of [YGGFL+Cat] + reveals that an internal lysine residue enhances the cleavage of the amide bond in C-terminal position (i.e., Lys–Xxx). The amine group of the lysine side chain initiates this reaction, leading to b n sequence ions with lactam structures, as corroborated by multiple-stage tandem mass spectrometry (MS n ) experiments. The selectivity for forming b-type ions at Lys–Xxx (vs. at other amide bonds) depends on Cat + , increasing in the order H + + + + ≈Na + . Investigation of [PTHIKWGD+Cat] + further shows that, when both His and Lys residues are present in internal positions, Lys–Xxx bonds are cleaved more selectively than His–Xxx bonds if Cat=Na (or Li), whereas both these bonds break with competitive rates if Cat=Ag. These trends are attributed to the different binding properties of silver vs. alkali metal ions. The enhanced dissociation of Lys–Xxx bonds to b-type fragments should be particularly useful in the sequence analysis of non-tryptic as well as incomplete tryptic digests which may contain internal lysine residues.
Extension of a perturbation technique for nonlinear two-point boundary-value problems

This paper extends the perturbation method of Roberts and Shipman by introducing the concept of a general partitioning scheme. Three specific realizations of the general partitioning idea (linear, variational, and quasilinear partitions) are described with supporting numerical results. To date, numerical experience with these methods indicates that the quasilinear partition method is the best.
Lack of effect of exercise on serum cholesterol levels in two types of experimental obesity.

Divers auteurs ont suppose recemment que la pratique journaliere d'exercices physiques peut abaisser le taux du cholesterol du sang. Cette hypothese a ete testee chez des souris normales et chez des souris representant deux classes d'obesite: des souris porteuses du syndrome hereditaire d'obesite-hyperglycemie (qui est accompagnee d'une hypercholesteremie genetique), representant l'obesite «de metabolisme», et des souris rendues obeses par les lesions hypothalamiques causees par l'administration d'aurothioglucose, representant l'obesite «de regulation». Trente jours d'exercice (une heure de course sur tapis roulant par jour) n'eurent aucun effet sur le taux du cholesterol du serum ni chez les souris normales, ni chez les deux groupes de souris obeses, et ceci en depit du fait que la duree et l'intensite de l'exercice quotidien etaient suffisantes pour reduire de facon significative le poids des souris obeses.
Forest understory soil temperatures and heat flux calculated using a Fourier model and scaled using a digital camera

The characterization of the solar radiation environment under a forest canopy is important for both understanding temperature-dependent biological processes and validating energy balance models. A modified sinusoidal model of soil heat conductivity was used to estimate subsurface temperature and heat flux from the uneven but periodic solar heating of the soil surface due to sun flecks from a forest canopy. Using a mobile sensor platform with an infrared thermometer along an 11 m transect, a sunfleck model of soil surface temperature was tested using soil surface temperature maxima, air temperatures, and photodiodes placed on the soil surface to measure sunflecks. A pan-tilt-zoom digital camera on a 10 m tower above the site was then used to capture a time series of panoramic images of sunflecks reflected from the soil surface and to scale the sunfleck temperature model to a wide area. Finally, this image-based model of surface temperatures was combined with the modified sinusoidal model for heat conduction to estimate soil subsurface temperatures and heat flux over a wide area due to sunflecks from a forest canopy.
Constitutively Active Signaling by the G Protein βγ-Subunit Mediates Intrinsically Increased Phosphodiesterase-4 Activity in Human Asthmatic Airway Smooth Muscle Cells

Signaling by the Gβγ subunit of Gi protein, leading to downstream c-Src-induced activation of the Ras/c-Raf1/MEK-ERK1/2 signaling pathway and its upregulation of phosphodiesterase-4 (PDE4) activity, was recently shown to mediate the heightened contractility in proasthmatic sensitized isolated airway smooth muscle (ASM), as well as allergen-induced airway hyperresponsiveness and inflammation in an in vivo animal model of allergic asthma. This study investigated whether cultured human ASM (HASM) cells derived from asthmatic donor lungs exhibit constitutively increased PDE activity that is attributed to intrinsically upregulated Gβγ signaling coupled to c-Src activation of the Ras/MEK/ERK1/2 cascade. We show that, relative to normal cells, asthmatic HASM cells constitutively exhibit markedly increased intrinsic PDE4 activity coupled to heightened Gβγ-regulated phosphorylation of c-Src and ERK1/2, and direct co-localization of the latter with the PDE4D isoform. These signaling events and their induction of heightened PDE activity are acutely suppressed by treating asthmatic HASM cells with a Gβγ inhibitor. Importantly, along with increased Gβγ activation, asthmatic HASM cells also exhibit constitutively increased direct binding of the small Rap1 GTPase-activating protein, Rap1GAP, to the α-subunit of Gi protein, which serves to cooperatively facilitate Ras activation and, thereby, enable enhanced Gβγ-regulated ERK1/2-stimulated PDE activity. Collectively, these data are the first to identify that intrinsically increased signaling via the Gβγ subunit, facilitated by Rap1GAP recruitment to the α-subunit, mediates the constitutively increased PDE4 activity detected in asthmatic HASM cells. These new findings support the notion that interventions targeted at suppressing Gβγ signaling may lead to novel approaches to treat asthma.
Psychosocial rehabilitation for patients recovering from acute myocardial infarction

standard questionnaire-based measures. A further limitation of our present clinical trial methodology is the difficulty in dealing with multiple interventions. After myocardial infarction, several interventions are required— smoking cessation, reducing cholesterol, exercise, and appropriate drug treatment. No clinical trial is likely to be set up to investigate this approach. The increased mortality rate among women in the active limb of the Canadian trial is a cause for concern. However, the numbers are small, the overall mortality is below predicted, and, if cardiac deaths and re-infarctions are combined (but procedural deaths excluded), the differences become very small (29 cardiac events in the intervention group, 27 in the control group). The difference in mortality rates is mainly related to arrhythmias, presumably unwitnessed sudden death. One of the earliest papers on psychological aspects of mycocardial infarction noted that patients who denied anxiety, who seemed to cope well in the coronary-care unit, had a much better prognosis. Denial has not been investigated formally as a useful mechanism in promoting recovery. Perhaps exploring anxieties in depth with clinical staff increases the risk of arrhythmia. This suggestion is only speculation but it is an attempt to explain the excess of arrhythmia in the intervention group and gives some rationale for the apparent benefit of denial.
Distribution of Red Drum Spawning Sites Identified by a Towed Hydrophone Array

Abstract Knowledge about fish spawning habits and habitats is an essential component of fisheries management. This paper reports on a survey of potential spawning sites for red drum Sciaenops ocellatus in the nearshore western Gulf of Mexico conducted using a towed hydrophone array. Two classes of red drum sounds could be distinguished. One was a low-frequency rumble with a prominent energy peak at approximately 150 Hz. The other was a clearly distinguishable call made by individual or small groups of red drum. Calls of individual red drum were detected along most sections of all transects. There were extensive areas along each transect where no close drumming was heard and where drumming rates were primarily low (<16 calls/min). Calls were detected in both extensive clusters and isolated occurrences along the transects. The distribution of drumming fish suggests that some, if not most, spawning takes place among widely dispersed individuals as opposed to highly aggregated groups. Only 7% of the 1-min sum...

Coupled errors on scattering phase shifts

Abstract During a least squares analysis of scattering data, a hypothetical energy dependence for the phase shifts often reduces the errors considerably. The mechanism of this error reduction becomes explicit only when the grid method of searching for a best fit is employed. Our illustration is drawn from low energy counter measurements on the pion nucleon system.
Polarization instability of femtosecond pulse-splitting in normally dispersive self-focusing media

Summary form only given. Through many numerical, analytical and recently also experimental investigations it has been verified that the collapse of self-focusing femtosecond pulses propagating through normally dispersive bulk third-order media is arrested by temporal dispersion due to the positive value of the GVD constant. In simple intuitive terms the arrest of the collapse may be explained as follows: for common experimental setups temporal dispersion may be neglected initially, thus making self-focusing induced by the combined effect of diffraction and nonlinearity the dominant effect throughout the early stages of pulse propagation. Hence, in the central part of the pulse (center in time) where the power in the transverse plane is above the threshold for self-focusing, off-axis energy is moved towards the peak of the pulse thereby increasing the peak-amplitude. Along with the increase in the peak-amplitude self-phase modulation starts to create significant gradients in the phase along the time-axis-a process which results in a flow of energy directed away from the peak, eventually bringing the peak power below the threshold for collapse. The majority of the studies of femtosecond pulse propagation in the past have used scalar models. A limitation of the various scalar models used is the restriction to the modelling of either linearly or circularly polarized pulses. It is the aim of the present work to illustrate how the inclusion of vectorial effects into the model may significantly alter the propagation scenarios known from the scalar case. In particular, we show how the linearly polarized solutions of the usual scalar models are unstable with respect to perturbations of the polarization state, and how self-focusing and pulse splitting in general may be controlled by altering the polarization state.
Being and Some Theologians

A crucial issue in contemporary theology is the doctrine of God and especially the nature of the divine reality. What kind of reality is God? How is God's reality like, unlike, and related to other kinds of reality? There are many ways to talk about the reality of God. I want to focus on one way, namely, God as being or beingitself, not because I believe that it is the best way to talk about God but because it is one of the oldest ways, because it seems to be undergoing something of a revival, and because I am baffled and intrigued by it.
Effect of non-leisure physical activity on mortality in U.S. adults: does propensity score matching make a difference?

Abstract Purpose To reanalyze results reported in 2008, using propensity score matching, to test the treatment effect of non-leisure physical activity on survival. Methods McCullagh's ordinal logit model was used to estimate propensity scores, separately for adults aged 35–59 and 60–74 years at baseline in the National Health and Nutrition Examination Survey I Epidemiologic Followup Study, for three levels of non-leisure activity. Each untreated adult (low non-leisure activity) was matched to two treated adults from the same age group, one with moderate and one with high non-leisure activity. Multivariable Cox proportional hazard regressions were fitted to the matched samples and compared with regressions fitted to unmatched samples. Results Except for moderate leisure-time activity and age, observed covariates were well balanced after matching. For adults aged 35–59 years, matched regressions showed smaller mortality reductions: 23% for moderate and 32% for high non-leisure activity, compared with low non-leisure activity. For adults aged 60–74 years, matched regressions showed a smaller mortality reduction for moderate non-leisure activity (29%) but a larger reduction for high non-leisure activity (47%). Conclusions In line with published reviews of conventional multivariable analysis versus propensity score matching, Cox regressions on matched and unmatched samples produced similar estimates of treatment effects for non-leisure activity, but the estimates from matched regressions were usually smaller.
Miscarriage effects on couples' interpersonal and sexual relationships during the first year after loss: women's perceptions.

Objectives: To describe inductively women’s perceptions of the effects of miscarriage on their interpersonal and sexual couple relationships (IR and SR); and, guided by the Lazarus Emotions and Adaptation Model, to compare IR and SR patterns 1 year after loss for differences in backgrounds, contexts, appraisals, reappraisals, and emotions. Methods: This was a secondary analysis of data gathered at 1, 6, 16, and 52 weeks postmiscarriage from 185 women. Text data were content-analyzed. Relationship differences were examined using MANCOVA with Bonferroni adjusted pairwise comparisons. Results: There were three relationship patterns: closer, as it was, and more distant. At 1 year, women whose IR (44%) was as it was (vs. closer [23%] or more distant [32%]) or whose SR (55%) was as it was (vs. more distant [39%]) coped less passively and appraised less miscarriage impact. Women whose IR or SR was as it was (vs. closer) were more likely to have children and (vs. more distant), miscarried at an earlier gestation, conceived again, and experienced fewer negative events. Those whose IR was closer or as it was and whose SR was as it was (vs. IR or SR more distant) had less disturbed emotions, more emotional strength, and partners who performed more caring acts. Women whose IR was closer and whose SR was as it was (vs. more distant) had partners who engaged in more mutual sharing. Conclusions: Women differed in perceptions of how miscarriage affected their IR and SR. The Lazarus Model helped explain those differences. Key words: miscarriage, perinatal loss, emotions, sexual relationship, couples, marriage.
Genetic diversity and reproductive biology in Warea carteri (Brassicaceae), a narrowly endemic Florida scrub annual.

Carter’s mustard ( Warea carteri) is an endangered, fire-stimulated annual endemic of the Lake Wales Ridge, Florida, USA. This species is characterized by seed banks and large fluctuations in plant numbers, with increases occurring in postdisturbance habitat. We investigated the mating system, patterns of isozyme variation, and effective population sizes of W. carteri to better understand its population biology and to comment on reserve designs and management proposals relevant to this species. Warea carteri is self-compatible and autogamous, and probably largely selfing. Measures of genetic variation in W. carteri were lower than values reported for species with similar ecological and life history traits (6.6% of loci polymorphic within populations, 1.87 alleles per polymorphic locus, and 0.026 and 0.018 expected and observed heterozygosity, respectively). The high average value for Nei’s genetic identity (0.989) reflects the paucity of genetic diversity. Genetic variation within populations was not correlated with aboveground population size, effective population size estimates (N e), or recent disturbance history. Much of the diversity detected was found among populations (FST 5 0.304). A significant cline in allele frequencies at one locus and a significant negative correlation between geographic distance and Nei’s genetic identity also point to spatial organization of genetic diversity. As a result we propose that reserve design should include the entire geographic range of W. carteri. We also recommend that the natural fire regime be mimicked.

Rill erosion on an oxisol influenced by a thin compacted layer

The presence of compacted layers in soils can induce subprocesses (e.g., discontinuity of water flow) and induces soil erosion and rill development. This study assesses how rill erosion in Oxisols is affected by a plow pan. The study shows that changes in hydraulic properties occur when the topsoil is eroded because the compacted layer lies close below the surface. The hydraulic properties that induce sediment transport and rill formation (i.e., hydraulic thresholds at which these processes occur) are not the same. Because of the resistance of the compacted layer, the hydraulic conditions leading to rill incision on the soil surface differed from the conditions inducing rill deepening. The Reynolds number was the best hydraulic predictor for both processes. The formed rills were shallow and could easily be removed by tillage between crops. However, during rill development, large amounts of soil and contaminants could also be transferred.
An analysis of visual masking, with a defense of 'Stopped Processing'

The use of a backward mask (a patterned mask which follows the target in time) to ‘stop the processing’ of the target illustrates an important application of masking – the study of the ‘microgenesis’ of visual perception, that is, visual processing over about the first one-fifth of a second. This paper provides evidence for stopped processing and some applications of this to object recognition and letter detection. The paper also discusses the notion of an ‘active filter’ which may help to account for Type-A masking but at best can only account for Type-B masking in part. I conclude that masking, while illuminating various areas of vision science, is under-utilized, perhaps because the theoretical justification for such masking is still uncertain, and perhaps because of the care needed to establish that the mask does indeed ‘stop’ processing.
A cooperative microbial fuel cell system for waste treatment and energy recovery

A cooperative microbial fuel cell (MFC) system was developed and investigated for its performance in waste treatment and bioenergy production. The system consisted of a conventional MFC and a dual-cathode MFC that was specially designed for nitrogen removal. Three feeding solutions, including a synthetic solution (acetate as an organic source), digested sludge and landfill leachate, were used as substrates. The MFC system removed more than 99% of chemical oxygen demand (COD) from the synthetic solution, and the organic removal mainly occurred in the anodes of the MFCs. Nitrogen, on the other hand, was removed in the cathodes of the MFC system, which achieved more than 98% removal of ammonium and 96% removal of total nitrogen. The MFC system also effectively treated the actual wastes and removed more than 85% of the total COD and 50–70% of the total nitrogen from the digested sludge and landfill leachate. The organic removal rates with the actual wastes were significantly higher than in other MFC systems. ...
Judgment of temporal duration as a function of numerosity

In judging brief stimulus duration, change of the number of dark dots from three to one resulted in underestimation, while similar change from three to five resulted in overestimation. Such a trend of temporal judgment was accentuated when the change was less frequent, demonstrating a contrast effect. But the analogous contrast effect was also obtained when the stimulus duration itself was changed.
The predominantly HEAT-like motif structure of huntingtin and its association and coincident nuclear entry with dorsal, an NF-kB/Rel/dorsal family transcription factor

Huntington's disease (HD) pathogenesis is due to an expanded polyglutamine tract in huntingtin, but the specificity of neuronal loss compared with other polyglutamine disorders also implies a role for the protein's unknown inherent function. Huntingtin is moderately conserved, with 10 HEAT repeats reported in its amino-terminal half. HD orthologues are evident in vertebrates and Drosophila, but not in Saccharomyces cerevisiae, Caenorhabditis elegans or Arabidopsis thaliana, a phylogenetic profile similar to the NF-kB/Rel/dorsal family transcription factors, suggesting a potential functional relationship. We initially tested the potential for a relationship between huntingtin and dorsal by overexpression experiments in Drosophila S2 cells. Drosophila huntingtin complexes via its carboxyl-terminal region with dorsal, and the two enter the nucleus concomitantly, partly in a lipopolysaccharide (LPS)- and Nup88-dependent manner. Similarly, in HeLa cell extracts, human huntingtin co-immunoprecipitates with NF-kB p50 but not with p105. By cross-species comparative analysis, we find that the carboxyl-terminal segment of huntingtin that mediates the association with dorsal possesses numerous HEAT-like sequences related to those in the amino-terminal segment. Thus, Drosophila and vertebrate huntingtins are composed predominantly of 28 to 36 degenerate HEAT-like repeats that span the entire protein. Like other HEAT-repeat filled proteins, huntingtin is made up largely of degenerate HEAT-like sequences, suggesting that it may play a scaffolding role in the formation of particular protein-protein complexes. While many proteins have been implicated in complexes with the amino-terminal region of huntingtin, the NF-kB/Rel/dorsal family transcription factors merit further examination as direct or indirect interactors with huntingtin's carboxyl-terminal segment.
Impact of DFIG based wind turbine generators on transient and small signal stability of power systems

The improved efficiency and controllability inherent with the doubly fed induction generators (DFIGs) is bringing this technology to the forefront of power industry. However, the dynamic behavior of these machines is different from those of synchronous machines. Apparently, the large penetration of these machines entails a change in dynamics and operational characteristics of the system as a whole. Given this assertion, the present paper develops an approach to analyze the impact of increased penetration of DFIG based wind turbine generators on transient and small signal stability of a large power system. The primary basis of the method is to convert the DFIG machines into equivalent conventional round rotor synchronous machines and then evaluate the sensitivity of the eigenvalues with respect to inertia. In this regard, modes that are both detrimentally and beneficially affected by the change in inertia are identified. These modes are then excited by appropriate disturbances and the impact of reduced inertia on transient stability performance is also examined. The proposed technique is tested on a large test system representing the Midwestern portion of the U.S. interconnection. The results obtained indicate that the proposed method effectively identifies both detrimental and beneficial impacts of increased DFIG penetration both for transient stability and small signal stability related performance.
Frequency-Hop Antijam Communications with Nonbinary Error-Control Coding

Reed-Solomon codes are nonbinary error-control codes that have been employed in military frequency-hop spread-spectrum systems to mitigate the effects of partial-band jamming and other frequency-selective disturbances. Hermitian codes, which are also nonbinary codes, have been suggested as alternatives because they have longer block lengths for the same alphabet size. More recently, construction methods and efficient iterative decoding techniques have been developed for nonbinary quasi-cyclic low-density parity-check (LDPC) codes. For channels in which the only disturbance is thermal noise, nonbinary quasi-cyclic LDPC codes with iterative decoding have been shown to be superior to Reed-Solomon codes of the same block length. We compare the performance of LDPC, Hermitian, and Reed-Solomon codes for frequency-hop transmission over channels with partial-band jamming. Performance results are also included for interleaved binary product codes with iterative decoding. Comparisons are made for nonbinary orthogonal modulation with coherent and noncoherent demodulation.
Comparative Single‐Point Diamond Scratching Behavior of a Cordierite Glass and Glass‐Ceramic

A comparative study was conducted of the single-point diamond scratching response of a cordierite glass and glass-ceramic. For the glass, deformation and material removal occurred by viscous flow at the lowest values of load, viscous flow combined with crack formation adjacent to the contact area over the intermediate load range, and extensive spoiling at the highest values of load. The density of the spalls and spall size were found to be proportional and inversely proportional to perpendicular scratching load, respectively. The glass-ceramic exhibited plastic flow and abrasive wear at loads as low as could be reliably measured, the particle size of the debris being of the order of the grain size. At the highest ranges of load, the glass-ceramic exhibited material removal by spall formation with a spall size proportional to load. At the lower ranges of load, the widths of the scratch for the glass and glass-ceramic were comparable. However, at the highest values of load tne size of the spall of the glass-ceramic was significantly less than the size of the spall in the glass.
Creating Technology-Enhanced, Learner-Centered Classrooms: K-12 Teachers' Beliefs, Perceptions, Barriers, and Support Needs

Although a wealth of literature discusses the factors that affect technol ogy integration in general and how to improve professional development efforts, few studies have examined issues related to learner-centered technology integration. Thus, this study aims to explore K–12 teachers’ beliefs, perceptions, barriers, and support needs in the context of creating technology-enhanced, learner-centered classrooms. The researcher used an online survey to collect data, and 126 teachers participated in the survey. The findings of this study provide practical insights into how to support teachers in creating technology-enhanced, learner-centered classrooms. This article discusses the implications for professional development and the need for paradigm change.
Magnetic Switching in Materials

Magnetic materials is an old subject poorly understood · by the majority of engineers. Recent research, particularly in magnetic films, has provided insights to understand and explain the behavior of the materials reacting to applied magnetic fields. Elementary domain theory is central to any significant comprehension. Dynamic behavior of nonlinear magnetic material cannot be analyzed entirely from the familiar B-H or hysteresis loop. However, the loop shape can be used to confirm behavior anticipated on the basis of domain theory and observation. Dynamic processes in magnetic material involve a change in the state, which is termed switching. A review of the fundamental principles pertinent to switching behavior and experimental data from a typical magnetic core are used to bring together theory and practical observation. Many recent applications of magnetic material require a more sophisticated understanding built upon such a knowledge of material behavior.
Kinematic Evaluation of Pulling Carry-on Luggage

From a kinematic standpoint, the objective of this study was to investigate forward pulling tasks that were rare in ergonomic studies, so handling carry-on luggage was determined as an application. Single-pole and traditional double-pole luggage was selected for the comparison under different conditions of load weights and walking speeds. Single-pole luggage had one curved and longer pole in the handle whereas double-pole luggage had two poles that were straight and aligned in parallel. Five male students participated in the study. Subjects walked on the specially fabricated doublewide treadmill at either self-chosen normal speeds or 20% faster than normal speeds with luggage of 15 or 23 kg load weights. During one stride, the peak angles, peak velocities and peak accelerations often segments including luggage were obtained from three-dimensional planes as kinematic parameters. The result showed that all three independent variables of luggage types, walking speeds, and load weights affected the motions of...
Attitude Basis, Certainty, and Challenge Alignment: A Case of Negative Brand Publicity

By integrating research from attitude challenge matching and consumer alignment and judgment revision, the authors explore how firms can position brands to insulate them from negative publicity and how consumers evaluate brands in reaction to such publicity. They introduce an important moderator of brand evaluation revision, prior brand attitude certainty, and propose that when negative publicity matches or “aligns” with the basis of a brand attitude, certainty in that attitude interacts with the attitude, determining the affect of the negative publicity on brand evaluations. The results of two experiments suggest that prior brand attitudes held with high certainty tend to “nsulate” brands, even when negative publicity matches or aligns with the bases of brand attitudes, whereas brand attitudes held with low certainty may exacerbate the effects of negative event publicity. The results also show that multiplex positioning (positioning a brand with both performance-and values-based attributes) may insulate brands more effectively from negative publicity.
When Bad Things Turn Good and Good Things Turn Bad: Sequences of Redemption and Contamination in Life Narrative and their Relation to Psychosocial Adaptation in Midlife Adults and in Students

Midlife adults (age 35 to 65) and college undergraduates provided lengthy, open-ended narrative accounts of personally meaningful episodes from the past, such as life-story high points, low points, turning points, and earliest memories. The oral (adult) and written (student) narratives were coded for redemption and contamination imagery. In the midlife sample, adults scoring high on self-report measures of generativity showed significantly higher levels of redemption and lower levels of contamination sequences. In both samples, redemption sequences in life narrative accounts were positively associated with self-report measures of psychological well-being, whereas contamination sequences predicted low levels of well-being among midlife adults. In addition, redemption sequence scores were a stronger predictor of well-being than were ratings of the overall affective quality of life-narrative accounts. The results are discussed with respect to the empirical literature of benefit-finding in the face of adversi...
MEDICS: ultra-portable processing for medical image reconstruction

Medical imaging provides physicians with the ability to generate 3D images of the human body in order to detect and diagnose a wide variety of ailments. Making medical imaging portable and more accessible provides a unique set of challenges. In order to increase portability, the power consumed in image acquisition -- currently the most power-consuming activity in an imaging device -- must be dramatically reduced. This can only be done, however, by using complex image reconstruction algorithms to correct artifacts introduced by low-power acquisition, resulting in image processing becoming the dominant power-consuming task. Current solutions use combinations of digital signal processors, general purpose processors and, more recently, general-purpose graphics processing units for medical image processing. These solutions fall short for various reasons including high power consumption and an inability to execute the next generation of image reconstruction algorithms. This paper presents the MEDICS architecture -- a domain-specific multicore architecture designed specifically for medical imaging applications, but with sufficient generality tomake it programmable. The goal is to achieve 100 GFLOPs of performance while consuming orders of magnitude less power than the existing solutions. MEDICS has a throughput of 128 GFLOPs while consuming as little as 1.6W of power on advanced CT reconstruction applications. This represents up to a 20X increase in computation efficiency over current designs.

Margaret Vento-Wilson, California State University, 1250 Bellflower Blvd., Long Beach, CA 90840, USA Email: Margaret{at}schoolsavers.com This research article describes the remediation of moderate stuttering in an adult client who experienced speech dysfluency for more than 40 years. Treatment took place at an urban residential rehabilitation mission where the client was court sentenced for a history of felonies and current narcotic sales and use. In conjunction with the operant conditioning instruction of the rehabilitation mission, the Ryan Fluency Program was implemented along with the initial use of pause time in response to the complex needs of the client. The article provides an overview of the assessment (Fluency Interviews, Criterion Tests) and treatment program. At present, 2.5 years post-initiation of treatment, the client has reported and been observed to have achieved smooth, forward-flowing, natural sounding speech throughout his work environment, family interaction, and daily life.

ASME Sec VIII Div 3 Fatigue Life Predictions Using Critical Plane Approach

ASME VIII Div 3 fatigue evaluation is based on the theory that cracks tend to nucleate along the slip lines oriented in the maximum shear stress planes. This code provides methods to calculate the fatigue stresses when the principal stress direction does not change (proportional loading) and axes change (nonproportional loading). When principal stress direction does not change within a fatigue cycle, shear stress amplitude is calculated only on the three maximum shear stress planes. But when the principal stress directions do change within a loading cycle, the plane carrying the maximum shear stress amplitude (also known as critical plane) cannot be easily identified and all planes at a point needs to be searched for the maximum shear stress amplitude.This paper describes the development of an ANSYS-APDL macro to predict the critical plane at each surface node of an FE model using the FEA stress results. This macro searches through 325 planes (at 10° increments along two angles) at each surface node and for each load step to identify the maximum shear stress and the corresponding normal stress for each surface node. The fatigue life is calculated for each surface node and is plotted as a color contour on the FEA model. This macro can be extended to calculate the fatigue life using other critical plane approaches such as the Findley and Brown-Miller models.Copyright © 2015 by ASME
Weaving Imperial Ideas: Iconography and Ideology of the Inca Coca Bag

AbstractWithout a system of writing, the Incas (ca. 1476-1534 c.e.) presided over an empire of orality and performance that stretched along the Andes Mountains from southern Ecuador to northern Chile. The Incas relied heavily on visual signals to impart information and organize their civilization. Textiles, among other crafted objects, were made to perform as visual emblems displaying ideas about imperial ideology and the authority embodied by individuals. This article explores the capacity of textiles to carry embedded meaning through the study of several specimens of Inca coca bags in the collections of the Dallas Museum of Art and the Museum of Fine Arts, Boston. Widespread throughout the Inca Empire and now housed in museum collections around the world, members of the Inca elite wore these elaborately woven bags to carry the leaves of the coca plant, a significant medicinal herb and sacrificial item. This article offers an iconographic analysis of the coca bag's surface embellishment and will establis...

Antibiosis to the Southern Chinch Bug by St. Augustinegrass Accessions

Twenty-six accessions of St. Augustinegrass, Stenotaphrum secundalum (Walt.) Kuntze, were evaluated under laboratory conditions for resistance to Blissus insularis Barber. ‘Floratam’, FA-46, 64, 73, 80, 87, 121, 131, 145, 217, and 243 when compared to common St. Augustinegrass exhibited significant antibiosis (P<0.05) to the caged adult southern chinch bug populations within 4–7 days. Floratam produced significantly more antibiosis (P<0.05) than any other selection when evaluated at 4 and 5 days but by the 7-day evaluation FA-46, 73, 87, 121, and 131 were not significantly different from Floratam. Significant (P<0.05) antibiosis to the 5th instars also was shown for 8 of the accessions including Floratam. A similar difference was also shown in the percentage of confined nymphs which survived but failed to molt to adults within 7 days for Floratam and FA-46, 131, and 173. Unlike Floratam which is very coarse-textured, the resistant selections FA-80, 121, 131, 145, and 243 are fine-textured. Like Floratam all 5 of these are relatively fast-growing, although FA-243 is the most vigorous accession.
Upstream propagating potential waves in the F109 turbofan engine inlet flow

Experiments were performed to study and quantify the unsteady velocity field upstream of the fan in an AlliedSignal F109 turbofan engine. In particular, phase-locked, three-component, velocity measurements were taken upstream of the fan at three fan RPM. The collected data were ensemble averaged and resolved into mean and unsteady velocity components. The resulting unsteady velocity components were further decomposed into elements of amplitude, frequency, and relative phase for the fundamental and first harmonic frequencies. Analysis of the decomposed phase data demonstrates, through unambiguous disturbance positionvs.-phase maps, that the measured velocity fluctuations are potential in nature and propagate at acoustic speeds upstream into the oncoming flow. Futhermore, the decomposed, axial-velocity, amplitude data exhibit peak-to-peak velocity fluctuations of nearly 20% of the mean-axial-velocity at locations near the fan; more importantly, the decomposed, azimuthal-velocity (swirl-velocity), amplitude data show peak-to-peak velocity fluctuations of nearly 50% of the mean-axial-velocity near the fan.
Senior Center Utilization by Black Elderly Adults: Social, Attitudinal and Knowledge Correlates

This study examined factors that affect utilization of senior centers by three groups of black elderly adults: attenders (n = 46) and nonattenders (n = 33) of a neighborhood senior center in one community and nonattenders (n = 27) in a comparable community without a neighborhood senior center. Variables investigated included social contact (with family and with friends), attitudes (disengagement potential, acceptability to others, commitment to become involved in senior centers) and knowledge (perception of senior centers). Results of the multivariate analysis of variance showed that sex, age, marital status, health, and transportation did not have a significant effect on the six variables studied. The three groups differed in commitment to become involved in senior centers, perception of senior centers, contact with family, and contact with friends. Similarities between the attenders and nonattenders in the comparable community suggest that the latter group are potential senior center participants.
Application of Neural Networks for Simultaneous Stereoscopic Tracking of Numerous Particles in Flow and Motion Measurements Measurements

Stereoscopic tracking technology has been developed for simultaneous tracking of numerous markers including particles and dots in three-dimensional space. It can offer an unprecedented capability for measuring three-dimensional (3-D) velocities in a fluid flow and displacement/deformation of a solid object. For fluid motion measurement, the flow can be seeded with small particles. For surface motion, the surface can be marked with dots while for deformation of a transparent object, it can be embedded with particles. In our effort for implementing the stereoscopic tracking technology, we employ neural networks for particle image overlap decomposition and simultaneous stereoscopic tracking of several thousands markers with high-resolution high-speed solid state cameras. One of the successful application examples is the measurement of parachute aerodynamics, for which the technique is termed stereoscopic tracking velocimetry (STV). By seeding the measurement volume with neutrally-buoyant helium soap bubbles as velocity markers, the parachute flow field can be visualized. The testing with a medium-scale model is conducted with high-speed high-resolution cameras. It is not feasible to provide a 3-D flow field of known velocity for assessing accuracy in 3-D flow measurement. For measurement accuracy and performance estimation, known velocity fields and corresponding stereoscopic particle images are thus obtained through 3-D numerical simulation of the aerodynamics flow around a parachute. Another successful application example is the deformation measurement of the brake system component of a heavy-duty truck, that is, slack adjuster. For the reliability evaluation of the measurement technology, numerical calculation for the stress analysis has been also performed for cross examination.
All-solid-state continuous-wave doubly resonant all-intracavity sum-frequency yellow laser at 570 nm

An all solid-state continuous-wave yellow laser at 570 nm is firstly reported.The yellow laser is from two Nd:YAG spectral lines of 1 444 nm and 946 nm with a nonlinear sum frequency,and the two spectral lines correspond to their energy levels of crystal transition for 4F3/2-4I15/2 and 4F3/2-4I9/2,respectively.By using a doubly folded-cavity,the yellow laser at 570 nm is obtained by a intra-cavity sum frequency mixing of type-II critical phase matching KTP crystal at 1 444 nm and 946 nm.The outpower of yellow laser vs incident pump powers is measured,results indicate that when pump powers injected into two Nd:YAG crystals are 24 W and 15 W,respectively,the 570 nm yellow laser of 560 mW can be obtained,and its power stability in 4 h is better than ±2.8%.Furthermore,the beam quality of the yellow laser is measured by a beam quality analyzer in an output power of 560 mW,and results show its beam quality factor M2 is 2.3 in the laser with a maximum sum-frequency output.

FoveAR: Combining an Optically See-Through Near-Eye Display with Spatial Augmented Reality Projections

Optically see-through (OST) augmented reality glasses can overlay spatially-registered computer-generated content onto the real world. However, current optical designs and weight considerations limit their diagonal field of view to less than 40 degrees, making it difficult to create a sense of immersion or give the viewer an overview of the augmented reality space. We combine OST glasses with a projectionbased spatial augmented reality display to achieve a novel display hybrid, called FoveAR , capable of greater than 100 degrees field of view, view dependent graphics, extended brightness and color, as well as interesting combinations of public and personal data display. We contribute details of our prototype implementation and an analysis of the interactive design space that our system enables. We also contribute four prototype experiences showcasing the capabilities of FoveAR as well as preliminary user feedback providing insights for enhancing future FoveAR experiences.
