The Support Magnet Cladding with Integrated IPS® Pick-Up Coil of Transrapid Vehicles

For the high-speed maglev system Transrapid the Inductive Power Supply (IPS®) has been developed on behalf of the BMVBS to afford a non-contact power supply of the vehicles (Zheng et al. 2005). In particular, the IPS® system substitutes the conventional system using power rails and current collectors. The essential vehicle components are pick-up coils integrated in the inner claddings of the support magnets. The development of the support magnet cladding including the qualification tests is presented.
Perspectives on Stress, Parenting, and Children’s Obesity-Related Behaviors in Black Families

Objective. In an effort to develop targets for childhood obesity interventions in non-Hispanic-Black (Black) families, this study examined parental perceptions of stress and identified potential links among parental stress and children’s eating patterns, physical activity, and screen-time. Method. Thirty-three self-identified Black parents or grandparents of a child aged 3 to 7 years were recruited from a large, urban Black church to participate in semistructured interviews. Interviews were audio-recorded, transcribed, and analyzed using thematic analysis. Results. Parents/grandparents described a pathway between how stress affected them personally and their child’s eating, structured (sports/dance) and unstructured (free-play) physical activity, and screen-time usage, as well as strategies to prevent this association. Five themes emerged: stress affects parent behaviors related to food and physical activity variably; try to be healthy even with stress; parent/grandparent stress eating and parenting; stress influences family cooking, food choices, and child free-play; and screen-time use to decrease parent stress. Negative parent/grandparent response to their personal stress adversely influenced food purchases and parenting related to child eating, free-play, and screen-time. Children of parents/grandparents who ate high-fat/high-sugar foods when stressed requested these foods. In addition to structured physical activity, cooking ahead and keeping food in the house were perceived to guard against the effects of stress except during parent cravings. Parent/child screen-time helped decrease parent stress. Conclusion. Parents/grandparents responded variably to stress which affected the child eating environment, free-play, and screen-time. Family-based interventions to decrease obesity in Black children should consider how stress influences parents. Targeting parent cravings and coping strategies that utilize structure in eating and physical activity may be useful intervention strategies.
X-band microwave absorption and dielectric properties of polyaniline-yttrium oxide composites

Abstract This article highlights the microwave absorption and dielectric attributes of synthesized polyaniline (PAni)-yttrium trioxide (Y2O3) composites. Temperature-dependent conductivity measurements were carried out in the temperature range of 300–473 K, which indicates the presence of hopping conduction. The PAni-Y2O3 composites showed semiconductor behavior with the exponential variation of inverse temperature dependence of electrical conductivity. Microwave measurements were carried out in the X-band (8–12 GHz) frequency; the composites exhibit absorption-dominated shielding effectiveness (SEA) in the range -33 to -35 dB (>99% microwave attenuation) and minimum electromagnetic reflection. The ε′ and ε″ values of the composites are in the range of 81.5–97.5 and 80–118.5, respectively. The PAni-Y2O3 composites showed significant improvement in microwave SE and complex permittivity of the composites, indicating the influence of Y2O3 in PAni.
On the Use of the Electrospinning Coating Technique to Produce Antimicrobial Polyhydroxyalkanoate Materials Containing In Situ-Stabilized Silver Nanoparticles

Electro-hydrodynamic processing, comprising electrospraying and electrospinning techniques, has emerged as a versatile technology to produce nanostructured fiber-based and particle-based materials. In this work, an antimicrobial active multilayer system comprising a commercial polyhydroxyalkanoate substrate (PHA) and an electrospun PHA coating containing in situ-stabilized silver nanoparticles (AgNPs) was successfully developed and characterized in terms of morphology, thermal, mechanical, and barrier properties. The obtained materials reduced the bacterial population of Salmonella enterica below the detection limits at very low silver loading of 0.002 ± 0.0005 wt %. As a result, this study provides an innovative route to generate fully renewable and biodegradable materials that could prevent microbial outbreaks in food packages and food contact surfaces.

Managing At-Risk Juvenile Offenders in the Community

More than a half-million juveniles are under community supervision as a result of violent or delinquent behavior. Research has shown that treatment can reduce their risk of reoffending. This article reviews and distills the key lessons from hundreds of empirical studies and metaanalyses and applies them to practice. The author argues for conducting systematic and developmentally informed risk assessments, selectively assigning intensive intervention to the highest risk offenders, focusing on criminogenic treatment targets, using proven interventions and treatment strategies, and applying rigor in implementation and follow-up.
SOA gain uniformity improvement employing a non-uniform biasing technique for ultra-high speed optical routers

In this paper, we propose a non-uniform biasing technique to improve the uniformity of the semiconductor optical amplifier (SOA) gain for ultra-high speed applications. In ultra-high speed applications, rapid gain recovery of the SOA is necessary to minimize the gain standard deviation and thus reducing system power penalties. A triangular shape biasing current is used in order to accelerate the SOA gain recovery while reducing the gain standard deviation. The effect of the non-uniform bias current on the SOA gain is investigated. The SOA is modeled using a segmentation method and the detailed theoretical analysis for the model is presented. The SOA gain and the output gain profiles achieved when injected with a burst of input Gaussian pulses for the non-uniform and the corresponding uniform techniques are also investigated. The operation principle is simulated and results show the boundaries and requirements in order to achieve the desired SOA bit rate for a range of different input powers. A reduction (at 1 mW input power) of 1.5 dB, 0.3 dB and 0.1 dB in the gain standard deviation is achieved for the input data rates of 10, 20 and 40 Gb/s, respectively.
Decisional Balance and Self-Efficacy for Sun Protection: Measurement Among Turkish Adolescents

BackgroundSun protection is important for skin cancer prevention, but many adolescents do not protect themselves from the sun. Instrumentation derived from the transtheoretical model (TTM) can be used to study the process of change in health behaviors like sun protection. ObjectiveThe purpose of this study was to translate and adapt TTM-based decisional balance and self-efficacy for sun protection scales from English to Turkish and assess psychometric properties of scores when the scales are used among Turkish adolescents. MethodsThe Decisional Balance Scale (DBS) and the Self-Efficacy Scale (SES) for sun protection were adapted to Turkish culture using translation and back-translation. The scales were administered to a total of 900 adolescents in two Turkish schools. Confirmatory factor analysis was used to assess dimensionality. External validity was evaluated by comparing subscale scores across reported stages of change for sun protection. ResultsReliability estimates for scores on the DBS Pros and DBS Cons and the SES Sunscreen Use scales were high and SES Hat Use and Sun Avoidance were moderate. The two-factor correlated model for the DBS and the three-factor correlated model for the SES reported in other studies were confirmed. Means increased across the stages of change for sun protection and sunscreen use for the DBS Pros and the SES subscales as predicted by the TTM, but the pattern of DBS Cons means did not. DiscussionScores from the Turkish version of the DBS and SES for sun protection were valid, reliable, and appropriate for Turkish culture. The pattern of means for the SES and DBS Pros across the stages of change supported propositions of the TTM. Theoretical inconsistencies in the pattern of DBS Cons scores across the stages of change suggest that greater attention to conceptualization and measurement of the DBS Cons for sun protection and sunscreen use is needed.
Measuring the distribution, abundance, and biovolume of zooplankton in an oligotrophic freshwater lake with a 710 kHz scientific echosounder

Acoustic surveys of the distribution and abundance of freshwater zooplankton were conducted in Lake Giles, an oligotrophic freshwater lake. Volume backscatter data from a 710 kHz scientific echosounder were converted to high‐resolution spatial and temporal numerical density estimates of small zooplankton. Vertical net tows of a 153 μm mesh closing bongo net at multiple depth intervals provided both identification of the types and sizes (0.5–1.5 mm length) of crustacean zooplankton present in the lake as well as an independent measurement of zooplankton numerical density. Net and acoustic estimates of zooplankton abundance, biovolume, and distribution were very similar. The improved resolution of the high‐frequency acoustic sampling provides insight into several aspects of freshwater zooplankton ecology including: separation of migrating and non‐migrating zooplankton, high resolution measurements of in situ zooplankton biovolume, calculation of in situ vertical velocities of migrating zooplankton, and fine‐scale (sub‐meter) horizontal and vertical zooplankton distribution during daytime, nighttime, and vertical migration events. These methods allow for more detailed and accurate estimates of zooplankton distribution than traditional net sampling methods can provide, including determining the total abundance of organisms within a specific habitat. They also provide higher resolution data in both space and time of smaller zooplankton taxa than have been measured previously in freshwater ecosystems.
Energy-Efficient Cooperative MIMO-Based Random Walk Routing for Wireless Sensor Networks

To improve energy efficiency of wireless sensor networks, this letter proposes a novel random walk routing algorithm based on the cooperative multi-input multi-output (MIMO) mechanism. For each hop of each walk, we investigate the adaption of communication modes [i.e., single-input single-output, virtual single-input multi-output, virtual multi-input single-output (vMISO), and virtual MIMO]. The parameters are jointly optimized for determining minimum energy consuming communication mode, including the number of transmitters and receivers, the set of cooperation nodes. Additionally, we consider only vMISO mode and derive the approximate optimal number of transmitters by exploiting the relationship with the transmission distances. The simulation results show that the proposed scheme can improve energy efficiency.
Social Health Social Support May Protect Against Development of Posttraumatic Stress Disorder : Findings From the Heart and Soul Study

Purpose. No prospective studies have examined the association of poor social support and development of posttraumatic stress disorder (PTSD) in patients with chronic illness. This study addresses this knowledge gap. Design. This prospective study examines the relationship of social support to the subsequent development of PTSD during a 5-year period. Setting. San Francisco Veterans Affairs Medical Center. Subjects. A total of 579 participants with cardiovascular disease did not have PTSD at baseline and returned for the 5-year follow-up examination. Measures. PTSD measured by Computerized Diagnostic Interview Schedule for DSM-IV. Social support measured by Interpersonal Support Evaluation List (ISEL). Analysis. Unconditional ordered logistic regression analyses were performed to yield the odds ratio of developing PTSD for a one-standard-deviation change in ISEL score. Results. Of 579 participants who did not have PTSD at baseline, approximately 6.4% (n1⁄4 37) developed PTSD. Higher baseline perceived social support was strongly protective against development of PTSD (OR 1⁄4 .60, p 1⁄4 .001). Results remained significant after adjustment for age, sex, race, income, and depression (OR 1⁄4 .69, p 1⁄4 .04). Of social support types examined, the ‘‘tangible’’ and ‘‘belonging’’ domains were most strongly associated with future PTSD status. Conclusion. Social support may impact development of PTSD. Interventions that optimize social support may be part of a PTSD prevention program designed to help individuals at risk of developing PTSD. (Am J Health Promot 2014;28[5]:294–297.)

A comparative study of the neural stem cell niche in the adult hypothalamus of human, mouse, rat and gray mouse lemur (Microcebus murinus)

The adult brain contains niches of neural stem cells that continuously add new neurons to selected circuits throughout life. Two niches have been extensively studied in various mammalian species including humans, the subventricular zone of the lateral ventricles and the subgranular zone of the hippocampal dentate gyrus. Recently, studies conducted mainly in rodents have identified a third neurogenic niche in the adult hypothalamus. In order to evaluate whether a neural stem cell niche also exists in the adult hypothalamus in humans, we performed multiple immunofluorescence labeling to assess the expression of a panel of neural stem/progenitor cell (NPC) markers (Sox2, nestin, vimentin, GLAST, GFAP) in the human hypothalamus and compared them with the mouse, rat and a non‐human primate species, the gray mouse lemur (Microcebus murinus). Our results show that the adult human hypothalamus contains four distinct populations of cells that express the five NPC markers: (a) a ribbon of small stellate cells that lines the third ventricular wall behind a hypocellular gap, similar to that found along the lateral ventricles, (b) ependymal cells, (c) tanycytes, which line the floor of the third ventricle in the tuberal region, and (d) a population of small stellate cells in the suprachiasmatic nucleus. In the mouse, rat and mouse lemur hypothalamus, co‐expression of NPC markers is primarily restricted to tanycytes, and these species lack a ventricular ribbon. Our work thus identifies four cell populations with the antigenic profile of NPCs in the adult human hypothalamus, of which three appear specific to humans.
LibRadar: Fast and Accurate Detection of Third-Party Libraries in Android Apps

We present LibRadar, a tool that is able to detect third-party libraries used in an Android app accurately and instantly. As third-party libraries are widely used in Android apps, program analysis on Android apps typically needs to detect or remove third-party libraries first in order to function correctly or provide accurate results. However, most previous studies employ a whitelist of package names of known libraries, which is incomplete and unable to deal with obfuscation. In contrast, LibRadar detects libraries based on stable API features that are obfuscation resilient in most cases. After analyzing one million free Android apps from Google Play, we have identified possible libraries and collected their unique features. Based on these features, LibRadar can detect third-party libraries in a given Android app within seconds, as it only requires simple static analysis and fast comparison. LibRadar is available for public use at http://radar.pkuos. org. The demo video is available at: https://youtu.be/GoMYjYxsZnI
Extending platform-based design to network on chip systems

Exploitation of silicon capacity will require improvements in design productivity and more scalable system paradigms. Asynchronous message passing networks on chip (NOC) have been proposed as backbones for billion-transistor ASICs. We present a novel layered backbone-platform-system (BPS) design methodology for development of network-on-chip based products. It combines and extends the distributed, parallel, embedded and platform-based design concepts in order to manage the diversity and complexity of NOC-based systems. The reuse of communication principles in various platforms, the reuse of platforms in product differentiation, and system-level decision-support methods are the cornerstones of our methodology. The presented mappability estimation and workload simulations demonstrate the feasibility of such methods.
Temperature history within laser sintered part cakes and its influence on process quality

Purpose The temperature distribution and history within laser sintered part cakes is an important aspect regarding the process quality and reproducibility of the polymer laser sintering process. This paper aims to an analysis of the temperature history during the build and cooling phase, which is decisive for powder ageing effects and the development of part quality characteristics. Design/methodology/approach A measurement system for three-dimensional in-process temperature measurements is set up and the influence of different parameters on the inner part cake temperature distribution and history is analyzed. In addition, position dependent temperature histories are finally correlated with powder ageing effects. Findings The main parameters influencing the part cake temperature history are figured out. Temperature inhomogeneities on the powder bed surface are detectable within the part cake, but only for a specific time or additional build height. Heat flux through the build frame results in different cooling rates dependent on z height. A combination of process parameters and build job layout results in individual, position-dependent temperature histories. As a consequence, completely different ageing intensities are found within one part cake. Research limitations/implications Temperature measurements are limited to part-free powder cakes so far. To transfer the results to other boundary conditions and machine types, simulation tools have to be developed and validated. Originality/value For the first time, the inner part cake temperature distribution and history have been measured during all build phases and with a high sensor density. The results of this work help to understand the temperature history dependency of powder and part properties and can therefore be used to develop optimized process controls.
Frequency of marine heatwaves in the North Atlantic and North Pacific since 1950

Extreme and large‐scale warming events in the ocean have been dubbed marine heatwaves, and these have been documented in both the Northern and Southern Hemispheres. This paper examines the intensity, duration, and frequency of positive sea surface temperature anomalies in the North Atlantic and North Pacific Oceans over the period 1950–2014 using an objective definition for marine heatwaves based on their probability of occurrence. Small‐area anomalies occur more frequently than large‐area anomalies, and this relationship can be characterized by a power law distribution. The relative frequency of large‐ versus small‐area anomalies, represented by the power law slope parameter, is modulated by basin‐scale modes of natural climate variability and anthropogenic warming. Findings suggest that the probability of marine heatwaves is a trade‐off between size, intensity, and duration and that region specific variability modulates the frequency of these events.
