Shear flow generation by drift waves revisited

The generation of shear flow by drift waves is an important area of investigation. In a recent paper [Chen et al., Phys. Plasmas 7, 3129 (2000)] an elegant formalism was developed for the generation of shear/zonal flows by drift waves in a toroidal plasma. The study of shear flow generation in fluids and plasmas is put into perspective. In this paper it is shown how a simple slab geometry analysis can lead to a similar dispersion relation and highlight the subtle differences between the slab and toroidal geometries.
Detection of estrus-related odors in cows by trained dogs.

Four German Shepherd and 2 Labrador Retriever dogs with previous experience in olfactory detection of explosives were trained to detect and respond to samples from estrous cows. Performance of the dogs was tested in trials consisting of simultaneous presentation of swabs from the vaginas of estrous and diestrous cows. Seven experiments were conducted, each consisting of several sessions of testing. In the first experiment, estrous-diestrous pairs of samples from the same cow (within-cow comparisons) were used repeatedly over successive sessions and the dogs averaged 8 1.6% correct detections of samples from estrous cows. In the second experiment, withincow pairs of samples were used again, but samples from a different cow were introduced after every 10 trials. The dogs averaged 68.1% correct detections in the second experiment. The third experiment was identical to the second, except that it took place in a dairy farmyard setting and the dogs’ overall score rose to 79.5% correct detections.The fourth, fifthand sixth experiments were conducted indoors as the first two had been. The fourth experiment was designed to make detection more difficult and within-cow pairs of samples were changed afterevery trial. The dogs averaged 80.7% correct detections. In the fifth experiment, pairs of samples from S cows were used during each of 3 sessionsof testing. Each sample from a cow in estrus was paired with a sample from the same cow indiestrusand also with the diestroussamples from each of the other 4 cows. The dogs averaged 80.9% correct detectionsof estrous samples. In the sixth experiment, a limited number of urine samples from estrous and diestrouscows was used and the dogs correctly identifiedthe estroussamples in 77.8% of the trials. In experiment 7, 4 dogs were tested in a farmyard settingwith livecows. Three cows, 1 in estrus and the other 2 between Days 6 and 12 postestrus,were used during each of 12 sessions of testing. Each session involved a new group of cows. The dogs averaged 87.3% correctdetections of estrous cows, The results of these experiments indicate that a specific odor is associated with estrus in cows and that specially trained dogs can detect the odor.
Detection of SRAM cell stability by lowering array supply voltage

In this paper, we discuss a design-for-test technique for the detection of cell stability in static random access memory (SRAM). The power supply to the memory array is isolated and independently accessible from an external terminal. By lowering the array supply voltage, the cell stability is degraded, making the defective cells susceptible to noises induced by read/write operations. On-silicon characterization result using 0.18 /spl mu/m CMOS technology is reported. It shows that the weak tailing bits in the statistical distribution can manifest themselves. The implementation of the test mode is inherently low-cost and can be combined with previously proposed methods for an improved detection capability.
Identificación de genes candidatos asociados a harinosidad en Prunus persica (L.) Batsch usando QTL de expresión

El duraznero (Prunus persica (L.) Batsch) es una especie frutal caducifolia de clima templado. A nivel mundial es la cuarta especie en importancia en terminos de produccion. Por otra parte, Chile es el principal exportador desde el hemisferio sur hacia EE.UU. , Europa y Asia. Sin embargo, para transportar duraznos a los mercados de destino, que se encuentran a distancias considerables, es necesario utilizar condiciones de almacenamiento refrigerado por largos periodos a bajas temperaturas, lo que genera desordenes fisiologicos conocidos como dano por frio o “chilling injury” (CI). Los sintomas del CI son pardeamiento, “bleeding”, perdida de sabor y harinosidad. Este ultimo es de gran importancia ya que ha sido identificado como uno de los principales problemas en la fruta por parte de los consumidores. La harinosidad se expresa como falta de jugo en la pulpa del fruto con la consecuente disminucion de la calidad organoleptica. Es por este motivo que resulta muy relevante estudiar y comprender el CI con el objeto de generar tecnologias para evitar su aparicion o reducir su efecto. El objetivo general de este trabajo fue identificar genes candidatos involucrados con harinosidad utilizando la asociacion de marcadores geneticos con los niveles de expresion de transcritos (fenotipo molecular) y los niveles de harinosidad (fenotipo), combinando la estrategia de analisis de QTLs con la secuenciacion masiva de transcriptomas de individuos de una poblacion F1 (‘O’Henry’ x ‘NR-053’; OxN) contrastantes para harinosidad. Para esto, se realizo una caracterizacion fenotipica de la poblacion para seleccionar los individuos contrastantes. Posteriormente, se secuencio el transcriptoma de tres frutos en cuatro estadios. Adicionalmente, con informacion proveniente de un mapa genetico previamente construido por el grupo de trabajo, se realizo un analisis de QTLs convencionales y de expresion para identificar los genes candidatos asociados al fenotipo. Se encontraron genes asociados a produccion de antocianinas, respuesta a estimulos, modificacion de pared celular y fitohormonas. En base a ellos fue posible hipotetizar que la harinosidad es gatillada a partir de un estres por frio durante la etapa de ablandamiento para madurez de consumo del fruto. Esta situacion genera una respuesta celular deficiente, no pudiendo reclutar correctamente factores que gatillan el ablandamiento o concentraciones suficientes de hormonas o metabolitos, lo cual finalmente culmina en el desarrollo del fenotipo harinoso en Prunus persica.
Simulation and Implication Using a Transfer Function Model for Switching Logic

Transfer functions are concise mathematical models representing the input/output behavior of a system and are widely used in many areas of engineering including system theory and signal analysis. We develop a framework for the construction of transfer function models for digital networks and demonstrate their application in simulation and implication. Rather than using a traditional switching theory model, the transfer functions are defined over vector spaces, H. The derivation of the transfer function is provided and it is applied to logic network simulation and implication.
2 The InTeracTIon of Gender WITh oTher SocIally conSTrucTed PrISmS

55 After considering what gender is and isn’t, we are going to complicate things a bit by looking at how a variety of other socially constructed categories of difference and inequality such as race, ethnicity, social class, religion, age, and sexuality shape gender. As is the case with prisms in a kaleidoscope, the interaction of gender with other social prisms creates complex patterns of identity and relationships for people across groups and situations. Because there are so many different social prisms that interact with gender in daily life, we can only discuss a few in this chapter; however, other social categories are explored throughout this book. The articles we have selected for this chapter illustrate three key arguments. First, gender is a complex and multifaceted array of experiences and meanings that cannot be understood without considering the social context within which they are situated. Second, variations in the meaning and display of gender are related to different levels of prestige, privilege, and power associated with membership in other socially constructed categories of difference and inequality. Third, gender intersects with other socially constructed categories of difference and inequality at all levels discussed in the introduction to this book—individual, interactional, and institutional.
Prefrontal Dopamine D1 and D2 Receptors Regulate Dissociable Aspects of Decision Making via Distinct Ventral Striatal and Amygdalar Circuits

Mesocortical dopamine (DA) regulates a variety of cognitive functions via actions on D1 and/or D2 receptors. For example, risk/reward decision making is modulated differentially by these two receptors within the prefrontal cortex (PFC), with D2 receptors enabling flexible decision making and D1 receptors promoting persistence in choice biases. However, it is unclear how DA mediates opposing patterns of behavior by acting on different receptors within the same terminal region. We explored the possibility that DA may act on separate networks of PFC neurons that are modulated by D1 or D2 receptors and in turn interface with divergent downstream structures such as the basolateral amygdala (BLA) or nucleus accumbens (NAc). Decision making was assessed using a probabilistic discounting task in which well trained male rats chose between small/certain or large/risky rewards, with the odds of obtaining the larger reward changing systematically within a session. Selective disruption of D1 or D2 modulation of separate PFC output pathways was achieved using unilateral intra-PFC infusions of DA antagonists combined with contralateral inactivation of the BLA or NAc. Disrupting D2 (but not D1) modulation of PFC→BLA circuitry impaired adjustments in decision biases in response to changes in reward probabilities. In contrast, disrupting D1 modulation of PFC→NAc networks reduced risky choice, attenuating reward sensitivity and increasing sensitivity to reward omissions. These findings reveal that mesocortical DA can facilitate dissociable components of reward seeking and action selection by acting on different functional networks of PFC neurons that can be distinguished by the subcortical projection targets with which they interface. SIGNIFICANCE STATEMENT Prefrontal cortical dopamine regulates a variety of executive functions governed by the frontal lobes via actions on D1 and D2 receptors. These receptors can in some instances mediate different patterns of behavior, but the mechanisms underlying these dissociable actions are unclear. Using a selective disconnection approach, we reveal that D1 and D2 receptors can facilitate diverse aspects of decision making by acting on separate networks of prefrontal neurons that interface with distinct striatal or amygdalar targets. These findings reveal an additional level of complexity in how mesocortical DA regulates different forms of cognition via actions on different receptors, highlighting how it may act upon distinct cortical microcircuits to drive different patterns of behavior.
Análisis del burnout y engagement en docentes: un estudio de diario

Son varios los estudios que consideran la labor docente como una profesion propensa al padecimiento de altos niveles de burnout (SQT). Esto es un hecho constatado si observamos la abundante bibliografia disponible sobre aspectos vinculados al estres docente y al padecimiento de graves problemas en la salud laboral. Si analizamos las investigaciones de las ultimas tres decadas, podemos observar como el estudio sobre el SQT-docente ha estado presente en numerosas publicaciones en diferentes paises y contextos. Esto lleva al estudio, durante la ultima decada, del burnout-docente en base a la prevencion y medidas paliativas que permitan minimizar los riesgos psicologicos atribuibles a este sindrome. Sin embargo, hoy dia este enfoque se encuentra en cuestion, ya que surgen voces discrepantes que cuestionan el estudio de los aspectos saludables del entorno en base a variables patologicas. La irrupcion de diferentes escuelas positivas abogan por impulsar el estudio de las fortalezas humanas como mecanismo que permita asentar un conocimiento sobre las causas que fomenten la salud y el bienestar. En base a esto, nuestra tesis doctoral, titulada “Analisis del Burnout y Engagement en docentes: Un estudio de diario”, pretende aportar una vision diaria sobre los procesos presentes en el desarrollo del sindrome burnout y engagement. Para ello, hemos recurrido a un estudio de diario multinivel que evalua aspectos intra e interpersonales, vinculados al ambito laboral como personal del colectivo de docentes en Espana. El proyecto plantea como objetivos generales 1) analizar del efecto de las demandas (sobrecarga) y recursos laborales (feedback, afecto, apoyo social y relacion con el alumnado) sobre la salud laboral de los docentes (burnout-engagement); 2) examinar el efecto de las puntuaciones diarias burnout-engagement sobre la salud general de los profesionales; y, por ultimo, 3) estudiar el efecto que tienen variables como el afecto y el apoyo social, tanto dentro como fuera del trabajo, en la salud general diaria.
Past Visions and Reconciling Views: Visualizing Time, Texture and Themes in Cultural Collections

We present a case study on visualizing a collection of historic drawings along its metadata structure while also allowing for close examination of the artifacts’ texture. With regards to the specific character of cultural heritage at the intersection of research, education, and public interest, the presented visualization environment aims at meeting the requirements of both researchers as well as a broader public. We present the results from a collaborative interdisciplinary research project that involved a cultural heritage foundation, art historians, designers, and computer scientists. The case study examines the potential of visualization when applied to, and developed for, cultural heritage collections. It specifically explores how techniques aimed at visualizing the quantitative structure of a collection can be coupled with a more qualitative mode that allows for detailed examination of the artifacts and their contexts by displaying high-resolution views of digitized cultural objects with detailed art historical research findings. Making use of latest web technologies, the resulting visualization environment allows for dynamic filtering and zooming of a collection of visual resources that are arranged along a contextualized timeline. We share insights from our collaborative design process and the feedback and usage data gathered during the deployment of the resulting prototype as a web application. We end with a discussion of transferability of carefully crafted and collaboratively negotiated visualizations of cultural heritage and raise questions concerning the applicability of our approach to related strands of humanities research.
Design and comparison of digital control loops analytical models, laboratory measurements, and simulation results

A buck converter with a digital controller is modeled analytically and compared to laboratory measurements and simulation results. These models will help the practicing engineer in understanding the new digital controllers. This presentation provides engineers less familiar with digital control some tools and insight into how to characterize the behavior of these systems. The models are validated by comparing their results with experimental measurements. An analytical synthesis approach will be given to estimate the control loop PID values to design and assure the stability of these systems. This approach reduces design iteration and the resulting design can be further optimized in the laboratory and by way of the simulator. Additional simulation techniques and methods are presented which will help both young and more experienced engineers evaluate the robustness of these control systems. Finally, real life practical tips are provided to avoid common simulation and modeling traps.
Application of modern teaching techniques in the educational process

Today students are using computers, cell phones and other electronic devices to communicate and to access information. New technologies fundamentally changed the way they interact with knowledge so the traditional approach to learning and teaching is no longer sufficient. In order to make the learning environment more interactive and enable students to learn easier and faster, modern teaching techniques need to be applied. There are many different teaching techniques that have emerged from the integration of technology in education such as: flipped teaching, whole brain teaching, gamification, social media, etc. Flipped teaching encourages students to study the course material before class by using readings, pre-recorded video lectures or research assignments. Class time is reserved for active learning strategies. Whole brain teaching helps stimulate both sides of the brain and emphasizes active learning in which students repeat core information and practice basic skills through humor and games. Gamification is a game-based learning technique that allows students learning through the use of games. Nowadays students are always connected to some social network. These students are easily motivated to engage with social media in the classroom. Experience from the School of Electrical Engineering in Zagreb shows that the use of different modern teaching techniques is making learning interesting and teaching more effective.
Nonlinear Resonant Circuits for Microwave Low Power Limiters

The letter comprises an analysis of nonlinear coupled resonant circuits for application in limiting low power microwave signals. It presents a novel approach to the use of the resonant circuit containing a nonlinear element which concerns obtaining power dependence of the quality factor and transmission losses without tuning resonant frequency. The basic theory of the single circuit is presented and examples provided of simulations in Microwave Office and measurements results of the designed two-stage limiter. The effect of transforming the input signal amplitude causes this type of circuit to be power-sensitive and allows to limit low power signals.
Development of real-time supervision HIL emulator of shaded PV systems

This paper presents the development of a real-time Supervision Hardware-in-the-Loop (HIL) emulator of shaded PV systems. This study is focused on shaded conditions due to the impact of shadows in the final energy production and the global structural healthy. In this context, we propose a methodology to emulate in real-time the shaded PV system behavior. This proposed methodology is intended for evaluation of supervision and fault detection strategies using a Hardware-in-the-Loop approach. This study takes advantage of FPGAs given their features of adaptability and parallel processing suitable for emulation of complex shaded PV systems. The proposed methodology employs the High Level Specification of Embedded Systems (HiLeS) for automatic VHDL code generation, and the graphical Systems Modeling Language (SysML) to represent the PV system behavior. Experimental results show the emulation of current-voltage behavior of PV modules under normal and shaded conditions. Emulation results are compared with experimental and conventional computational approaches shown a high degree of accuracy.
General implementation of arbitrary nonlinear quadrature phase gates

We propose general methodology of deterministic single-mode quantum interaction nonlinearly modifying single quadrature variable of a continuous variable system. The methodology is based on linear coupling of the system to ancillary systems subsequently measured by quadrature detectors. The nonlinear interaction is obtained by using the data from the quadrature detection for dynamical manipulation of the coupling parameters. This measurement-induced methodology enables direct realization of arbitrary nonlinear quadrature interactions without the need to construct them from the lowest-order gates. Such nonlinear interactions are crucial for more practical and efficient manipulation of continuous quadrature variables as well as qubits encoded in continuous variable systems.
From employee representation to problem-solving: Mainstreaming OHS management

The role of occupational health and safety representatives is changing. A study in 60 Danish enterprises indicates that representation, and especially negotiation on behalf of colleagues, has diminished. The work environment is mainstreamed in many enterprises and is rarely an area of conflict. The role of OHS representatives has accordingly changed to focus on solving specific problems in the workplace as an integrated part of daily operations. Both management and colleagues consider the OHS representatives as a resource that can be utilized to manage the work environment. The consequences of this development for the employees may be a stronger joint management–employee effort to improve the work environment, but also management domination and an accordingly weaker employee voice in some companies.
Lithium Blocks the c-Jun Stress Response and Protects Neurons via Its Action on Glycogen Synthase Kinase 3

ABSTRACT Lithium has been used as an effective mood-stabilizing drug for the treatment of manic episodes and depression for 50 years. More recently, lithium has been found to protect neurons from death induced by a wide array of neurotoxic insults. However, the molecular basis for the prophylactic effects of lithium have remained obscure. A target of lithium, glycogen synthase kinase 3 (GSK-3), is implicated in neuronal death after trophic deprivation. The mechanism whereby GSK-3 exerts its neurotoxic effects is also unknown. Here we show that lithium blocks the canonical c-Jun apoptotic pathway in cerebellar granule neurons deprived of trophic support. This effect is mimicked by the structurally independent inhibitors of GSK-3, FRAT1, and indirubin. Like lithium, these prevent the stress induced c-Jun protein increase and subsequent apoptosis. These events are downstream of c-Jun transactivation, since GSK-3 inhibitors block neuronal death induced by constitutively active c-Jun (Ser/Thr→Asp) and FRAT1 expression inhibits AP1 reporter activity. Consistent with this, AP1-dependent expression of proapoptotic Bim requires GSK-3-like activity. These data suggest that a GSK-3-like kinase acts in tandem with c-Jun N-terminal kinase to coordinate the full execution of the c-Jun stress response and neuronal death in response to trophic deprivation.
