Ultrafast Steady-State Multiphysics Model for PM and Synchronous Reluctance Machines

A new technique for coupling the electromagnetic, thermal, and airflow analysis is proposed particularly for electric machines that exhibit reduced dependence of core losses with temperature and load and have low rotor losses. Within the overall iterative loop, another inner loop that cycles only the thermal calculations and employs a simplified model to estimate losses is introduced. The thermal and airflow analysis models the conduction, radiation, and convection heat transfer and is based on equivalent circuit networks. A computationally efficient finite-element (FE) technique is employed for the electromagnetic field analysis. The combination of algorithms results in ultrafast processing as the number of outer loop iterations, which include electromagnetic FE analysis, is minimized. The overall computational time is significantly reduced in comparison with the conventional method, such that the new technique is highly suitable for large-scale optimization studies. Example simulation studies and measurements from an integral horsepower interior permanent-magnet motor are included to support validation.
Reaction–diffusion fronts with inhomogeneous initial conditions

Properties of reaction zones resulting from type reaction–diffusion processes are investigated by analytical and numerical methods. The reagents A and B are separated initially and, in addition, there is an initial macroscopic inhomogeneity in the distribution of the B species. For simple two-dimensional geometries, exact analytical results are presented for the time evolution of the geometric shape of the front. We also show using cellular automata simulations that the fluctuations can be neglected both in the shape and in the width of the front.
A Comparison of Traditional and Simple Evolutionary HillClimbing Methods for Solving Static and Recurrent Dynamic Constraint Satisfaction Problems

In this paper we compare the performance of Minton’s et al. min-conflicts hill-climbing (MCHC) algorithm [16], Wallace and Freuder’s MCHC algorithm [25], Morris’ breakout algorithm (BA) [17, 18], and modified variants of the BA that we developed on static constraint satisfaction problems (CSPs) and recurrent dynamic constraint satisfaction problems (rDCSPs). Also, we used a simple evolutionary hill-climber (SEHC) to solve rDCSPs. In this study, our results show that our modified variants of the BA and Morris’ BA are the most efficient algorithms in terms of average number of candidate solutions, average number of constraint checks, and average clock cycles on our CSPs. The largest population SEHC algorithm was the most efficient in terms of average solution instability on our rDCSPs.
C3-Sched — A cache covert channel robust cloud computing scheduler

Several cloud schedulers have been proposed in the literature with different optimization goals such as reducing power consumption, reducing the overall operational costs or decreasing response times. A less common goal is to enhance the system security by applying specific scheduling decisions. The security risk of covert channels is known for quite some time, but is now back in the focus of research because of the multitenant nature of cloud computing and the co-residency of several per-tenant virtual machines on the same physical machine. Especially several cache covert channels have been identified that aim to bypass a cloud infrastructure's sandboxing mechanism. For instance, cache covert channels like the one proposed by Xu et. al. use the idealistic scenario with two alternately running colluding processes in different VMs accessing the cache to transfer bits by measuring cache access time. Therefore, in this paper we present a cascaded cloud scheduler coined C3-Sched aiming at mitigating the threat of a leakage of customers data via cache covert channels by preventing processes to access cache lines alternately. At the same time we aim at maintaining the cloud performance and minimizing the global scheduling overhead.
Assessment of Effectiveness of Cognitive-Behavioral Group Training on Self-Esteem and Achievement Motivation of High School Students

Background: Based on researches done in recent decades, there are several therapeutic approaches to increase self-esteem and achievement motivation of students. Among these methods, we can refer to cognitive-behavioral therapy. The purpose of this research is assessment of effectiveness of cognitive-behavioral group training on self-esteem andachievement motivation of students. Methods: The research method was experimental with two- grouped pre-test and post- test design, experimental group and control group. The statistical population includes all students of high schools in Sarakhs (educational year 2012-2013). (N=85). Participants were chosen by available sampling method and randomly assigned to an experimental (15 boys) and a control group (15 boys). The experimental group received cognitive-behavioral group training through 8 sessions of 1 hour, while the control group received no training at all. For assessing the research variables, Alis Pop self- esteem questionnaire and Edwards’s achievement motivation questionnaire were done before and after completion of the trainings. The collected data were analyzed using independent and dependent T test by SPSS statistical software. Results: The study demonstrated that cognitive-behavioral training had positive effects on students’ self-esteem (P<0.001) and achievement motivation (P<0.001) in comparison to control group. Conclusions: In general, it can be concluded that cognitive- behavioral training were found effective in increasing self-esteem and achievement motivation.
Flow Cytometric Analysis of Heterogeneity in Blood Group-related Antigen Expression in a Human Urinary Bladder Carcinoma Cell Line , 647 V 1

Previous immunohistological studies showed a relationship between expression of blood group-related antigens (BG-Ag) and invasive potential in human urinary bladder carcinoma, but the marked variability of antigen staining within many individual tumors has obscured the biological basis of this finding. We studied the expression of the A, H, and T (Thomsen-Friedenreich) BG-Ag by flow cytometry in a human bladder carcinoma cell line (647V) using fluoresceinated BG-Ag-specific lectins (Dolichos bifloris, Ulex europaeus, andArachis hypogaea). Cell cycle com partments were quantitated by flow cytometry using propidium iodide staining. Expression of all three antigens was highly variable, but staining for each antigen produced a distinct profile. T antigen expression appeared independent of A or H antigen expression. Cell populations sorted by T antigen expression showed heritable antigenic differences persistent over many weeks in culture. However, much of the T antigen variability was nonheritable, since the stable staining profiles of the sorted cells were intermediate between the parental and the profiles obtained immediately after sorting. The nonheritable antigenic variation did not appear entirely explainable by cell size or cell cycle fluctuation. These results were confirmed by isolating 64 clones from the dim part of the T antigen staining profile, 19 of which had a persistently dim phenotype. The variability of BG-Ag expression by human bladder carcinoma cells in vitro may explain the staining patterns observed in the study of antigen expression in resected human bladder carcinomas.
Interconnect Power Optimization Based on Timing Analysis

In traditional floorplanners, the lack of information about timing schedule from high level synthesis (HLS) often leads to the failure or iterations of timing schedule design. In this paper, timing analysis with interconnect delay is introduced to the process of floorplanning, which enables the timing schedule information considered in physical design. Furthermore, based on timing schedule information, the timing slacks along datapaths are used to optimize the interconnect power consumptions. Without violating timing specification, we propose a delay budget method to distribute the slacks along interconnects in order to optimize the total interconnect power. Experimental results show that our interconnect power optimization method based on timing analysis can optimize the packing to meet the cycle time requirement effectively and save the interconnect power consumption about 13.2% on average
Th1-like antifilarial immune responses predominate in antigen-negative persons

To characterize immune responses associated with the putatively immune state in bancroftian filariasis (that is, both microfilaria and antigen free), humoral and cellular responses were compared among antigen- and microfilaria-negative, antigen-positive and microfilaria-negative, and microfilaria-positive individuals. Antifilarial isotype levels were measured by enzyme-linked immunosorbent assay. Peripheral blood mononuclear cell responses were measured by proliferation, by bioassay for interleukin-2 (IL-2) and IL-10, and by reverse transcription-PCR for IL-4, IL-5, and gamma interferon. The absence of circulating filarial antigen was associated with Th1-like responses, including significantly higher proliferative (P < 0.001) and IL-2 (P = 0.008) responses and a higher prevalence of gamma interferon (0.02 < P < 0.1) responses. Significantly elevated antifilarial immunoglobulin G4 (IgG4) levels (P = 0.0035) were associated with antigenemia, whereas microfilaremia was associated with significantly decreased antifilarial IgG2 levels (P = 0.0014). IL-4 mRNA levels were not significantly different among the three groups; however, there was a subpopulation of microfilaremic individuals who did not make detectable levels of IL-4 mRNA and who produced low antifilarial IgG4 levels compared with those of individuals who had detectable levels of IL-4 mRNA. IL-5 mRNA levels also were not significantly different among groups; however, more microfilaremic individuals produced IL-5 mRNA in response to adult filarial antigens, and total parasite-specific IL-4 and IL-5 mRNA levels were significantly correlated (P = 0.05). Although longitudinal data are not currently available, the elevated Th1-like responses in antigen- and microfilaria-negative individuals are consistent with the hypothesis that these responses contribute to protection in putatively immune individuals.
A Direct Interaction of Axonin-1 with Ngcam-Related Cell Adhesion Molecule (Nrcam) Results in Guidance, but Not Growth of Commissural Axons

An interaction of growth cone axonin-1 with the floor-plate NgCAM-related cell adhesion molecule (NrCAM) was shown to play a crucial role in commissural axon guidance across the midline of the spinal cord. We now provide evidence that axonin-1 mediates a guidance signal without promoting axon elongation. In an in vitro assay, commissural axons grew preferentially on stripes coated with a mixture of NrCAM and NgCAM. This preference was abolished in the presence of anti–axonin-1 antibodies without a decrease in neurite length. Consistent with these findings, commissural axons in vivo only fail to extend along the longitudinal axis when both NrCAM and NgCAM interactions, but not when axonin-1 and NrCAM or axonin-1 and NgCAM interactions, are perturbed. Thus, we conclude that axonin-1 is involved in guidance of commissural axons without promoting their growth.
Effect of GnRH analogues on apoptosis and release of interleukin-1beta and vascular endothelial growth factor in endometrial cell cultures from patients with endometriosis.

BACKGROUND The aim of the present study was to evaluate the effect of GnRH analogues on the in-vitro eutopic endometrial cell apoptosis and release of interleukin-1beta (IL-1beta) and vascular endothelial growth factor (VEGF). METHODS Biopsy specimens of eutopic endometrium obtained from 16 women with untreated endometriosis and 14 controls were studied. Apoptosis, IL-1beta and VEGF release were evaluated in epithelial endometrial cell cultures after incubation with leuprolide acetate (LA) as GnRH agonist, antide as GnRH antagonist, and a combination of both. The percentage of apoptotic cells was evaluated by the acridine orange-ethidium bromide technique, and IL-1beta and VEGF concentrations were assessed by using commercial enzyme-linked immunosorbent assay (ELISA) kits. RESULTS We found that LA (100 ng/ml) enhanced apoptosis in endometrial cell cultures from endometriosis patients and controls and this effect was reversed by antide at 10(-7) mol/l. IL-1beta and VEGF release was downregulated by LA in cultures from controls and endometriosis patients. The addition of antide 10(-7) mol/l reversed this inhibition. Endometrial cultures treated with antide at 10(-7) mol/l did not show any significant effects compared with basal conditions. CONCLUSIONS GnRH agonists appear to have a direct effect in endometrial cells cultures, by enhancing the percentage of apoptotic cells and decreasing the release of pro-mitogenic cytokines such as IL-1beta and VEGF.
Automated search for galactic star clusters in large multiband surveys: I. Discovery of 15 new ope

Aims. According to some estimations, there are as many as 100 000 open clusters in the Galaxy, but less than 2000 of them have been discovered, measured, and cataloged. We plan to undertake data mining of multiwavelength surveys to find new star clusters. Methods. We have developed a new method to search automatically for star clusters in very large stellar catalogs, which is based on convolution with density functions. We have applied this method to a subset of the Two Micron All Sky Survey catalog toward the Galactic anticenter. We also developed a method to verify whether detected stellar groups are real star clusters, which tests whether the stars that form the spatial density peak also fall onto a single isochrone in the color–magnitude diagram. By fitting an isochrone to the data, we estimate at the same time the main physical parameters of a cluster: age, distance, color excess. Results. For the present paper, we carried out a detailed analysis of 88 overdensity peaks detected in a field of 16 × 16 degrees near the Galactic anticenter. From this analysis, 15 overdensities were confirmed to be new open clusters and the physical and structural parameters were determined for 12 of them; 10 of them were previously suspected to be open clusters by Kronberger (2006) and Froebrich (2007). The properties were also determined for 13 yet-unstudied known open clusters, thus almost tripling the sample of open clusters with studied parameters in the anticenter. The parameters determined with this method showed a good agreement with published data for a set of well-known clusters.
Blended Interaction Spaces for Collaborative Design

In this workshop paper, we give an overview of our work and present our visions and ongoing research in developing Blended Interaction spaces for collaborative design. We then identify key themes and challenges pertinent for the workshop.
The genera, reflexibility and simplicity of regular maps

This paper uses combinatorial group theory to help answer some long-standing questions about the genera of orientable surfaces that carry particular kinds of regular maps. By classifying all orientably-regular maps whose automorphism group has order coprime to g −1, where g is the genus, all orientably-regular maps of genus p+1 for p prime are determined. As a consequence, it is shown that orientable surfaces of inﬁnitely many genera carry no regular map that is chiral (irreﬂexible), and that orientable surfaces of inﬁnitely many genera carry no reﬂexible regular map with simple underlying graph. Another consequence is a simpler proof of the Breda–Nedela–Siraň classiﬁcation of non-orientable regular maps of Euler characteristic −p where p is prime.
FPGA implementation of a license plate recognition SoC using automatically generated streaming accelerators

Modern FPGA platforms provide the hardware and software infrastructure for building a bus-based system on chip (SoC) that meet the applications requirements. The designer can customize the hardware by selecting from a large number of pre-defined peripherals and fixed IP functions and by providing new hardware, typically expressed using RTL. Hardware accelerators that provide application-specific extensions to the computational capabilities of a system is an efficient mechanism to enhance the performance and reduce the power dissipation. What is missing is an integrated approach to identify the computationally critical parts of the application and to create accelerators starting from a high level representation with a minimal design effort. In this paper, we present an automation methodology and a tool that generates accelerators. We apply the methodology on an FPGA-based license plate recognition (LPR) system used in law enforcement. The accelerators process streaming data and support a programming model which can naturally express a large number of embedded applications resulting in efficient hardware implementations. We show that we can achieve an overall LPR application speed up from 1.2times to 2.6times, thus enabling real-time functionality under realistic road scenes
EFECTOS DE LA ESTIMULACIÓN COGNITIVA EN LA ENFERMEDAD DE ALZHEIMER: IMPLICACIÓN DE BDNF

Education and cognitive occupations is commonly associated to reduced risk of Alzheimer? s disease (AD) dementia. Animal studies have demonstrated that cognitive stimulation (CS) achieved by social/physical activities and/or enriched environments compensates for memory decline. We have elaborated a novel paradigm of CS that is devoid of physical/social activity and enriched environments. 4 months-old Tg2576 mice were cognitively trained for 8 weeks and, after a break of 8 months, long-lasting effects of CS on cognitive abilities and AD-like pathology were measured. MWM and NOR tests showed that deficits in spatial and recognition memories were compensated by CS. These outcomes were accompanied by increased levels of hippocampal post-synaptic markers (PSD95 and NR1) and proteins involved in synaptic formation (Arc, â-catenin). CS softened amyloid pathology in terms of reduced levels of Aâ1-42 and the dodecameric assembly, referred as Aâ*56. CS appeared to affect the APP processing since differences in levels of ADAM17, BACE1 and C99/C83 ratio were found. Tau hyper-phosphorylation and high activities of Tau kinases were also reduced by CS. In contrast, CS did not induce any of these molecular changes in wild-type mice. The present findings suggest beneficial and long-lasting effects of CS early in life on cognitive decline and AD-like pathology. In this research work we have also characterized the role of BDNF on a new mechanism by which cognitive stimulation exerts its beneficial effects on cognitive decline and AD-like pathology.
A High-Throughput Eight-Channel Probe Head for Murine MRI at 9.4 T

Murine MRI studies are conducted on dedicated MR systems, typically equipped with ultra‐high‐field magnets (≥4.7 T; bore size: ∼12–25 cm), using a single transmit‐receive coil (volume or surface coil in linear or quadrature mode) or a transmit‐receive coil combination. Here, we report on the design and characterization of an eight‐channel volume receive‐coil array for murine MRI at 400 MHz. The array was combined with a volume‐transmit coil and integrated into one probe head. Therefore, the animal handling is fully decoupled from the radiofrequency setup. Furthermore, fixed tune and match of the coils and a reduced number of connectors minimized the setup time. Optimized preamplifier design was essential for minimizing the noise coupling between the elements. A comprehensive characterization of transmit volume resonator and receive coil array is provided. The performance of the coil array is compared to a quadrature‐driven birdcage coil with identical sensitive volume. It is shown that the miniature size of the elements resulted in coil noise domination and therefore reduced signal‐to‐noise‐ratio performance in the center compared to the quadrature birdcage. However, it allowed for 3‐fold accelerated imaging of mice in vivo, reducing scan time requirements and thus increasing the number of mice that can be scanned per unit of time.

On the incremental deployment of overlay information centric networks

It has long been realized that the proliferation of information-centric applications and services must be reflected in a corresponding shift of the underlying Internet architecture. Even though users increasingly focus on the desired information, the underlying network still focuses on the endpoints providing/consuming this information and in many cases this mismatch has resulted in an inefficient utilization of network resources, as demonstrated by peer-to-peer (P2P) and file sharing applications. In view of this situation, many research projects have focused on the investigation of alternative networking models centered around information. However, less attention has been paid to the transition process from the current end host centric model to an information centric one. In this paper, we propose an overlay multicast-enabled, publish-subscribe architecture and focus on its gradual deployment both inside administrative domain boundaries as well as across the Internet. Our simulation results demonstrate the benefits for individual network operators as they gradually adopt our new networking model, and shed further light on the extent of deployment required within an administrative domain in order for our approach to perform optimally.
Explaining the Food Stamp Cash-Out Puzzle

Empirical studies have shown that food stamp participants spend a higher proportion of their benefit on food than they would with an equivalent amount of cash. Our study demonstrates that this result can be explained by the decision-making behavior of multi-adult households. Multi-adult households spend a higher proportion of their food stamp benefit than they would with an equivalent amount of cash. In contrast, single-adult households show little difference in food spending between food stamps and an equivalent amount of cash. Because over 30 percent of food stamp participants are in multi-adult households, switching from food stamps to cash may reduce food purchases of these needy households. If that is indeed the case, the use of food stamps and other in-kind benefits may be more desirable than other forms of assistance.
Community Service Learning as Critical Curriculum: Promoting International Students' Second Language Practices

Grounded in the whole person perspective of language learners and the concepts of investment and L2 socialization, this qualitative study explores how community service learning (CSL) contributes to international students' L2 practices and identity development. This study finds that CSL creates “a pedagogical contact zone” outside the formal language classroom in which students are exposed to authentic L2 practices and discourse acquisition. CSL is a critical curriculum for students' learning, repositioning, cooperating, and empowering. It transforms the multiple spaces of students' worlds and connects the boundaries between university and community and between foreign culture and American culture. CSL promotes students' L2 practices and positions in the community as worthy cultural and social beings. This study advocates that CSL is a legitimate language practice. It offers students an alternative discourse, community contact, and an invitation to reading and understanding the world. Suggestions for curriculum implications are discussed.
