Adaptive nonsingular terminal sliding model control of the suspension system for a bearingless permanent magnet synchronous motor

To improve the stability and disturbance rejection for the suspension system of a bearingless permanent magnet synchronous motor (BPMSM), an adaptive nonsingular terminal sliding mode (NTSM)control is proposed in suspension system. Radial basis function neural network(RBFNN) is introduced to estimate the upper bound of the uncertainties, and faster convergence speed of system state variables can be obtained during the whole process. The suspension control system for the bearingless motor with rotor flux orientation is also implemented on the basis of proposed controller. Simulation results show that the proposed method is effective, higher robustness in disturbances is achieved.
Platform-Driven Design for Serious Games, Collaboration and Multilayer methodology

The multilayer methodology involves several concepts for serious game design; it can increase the collaboration between several actors of design, obtaining a more efficient serious game. Although it requires a specific environment to provide an effective assistance and visibility during the development of serious games, it improves on the combination of learning and entertainment fields. In this paper, we present the multilayer methodology and how can actors collaborate to provide an effective design, then, we study the implementation of the methodology on an online platform. This methodology can make the design process more structured and improve the collaboration purpose. Finally, we propose a new environment of serious game design.
Will a Clinical Approach Make Education Research More Relevant for Practice?

The way in which researchers view education differs fundamentally from the way in which teachers view education. These different outlooks are (partly) a consequence of the different work roles of researchers and teachers. This article explores the question of whether it is really inevitable that research and practice each establish different views of education. The author shows that the definition of the role of researchers draws heavily on a dualistic view that separates knowledge from skill and detaches human intellectual faculties from other human faculties. Although such dualistic notions are highly contested nowadays, they are institutionalized in the definition of the work of researchers and the purpose of research. The contribution of this article lies in the presentation of a unifying framework in which the views of teachers and researchers can be (at least partially) reconciled in the context of clinical research practice.
Morphological Investigation of Iron‐Induced Epileptic Rats: With Special Reference to C‐fos Immunohistochemistry and Iron Staining

Abstract: We investigated the iron‐induced epileptic rats with special reference to c‐fos immunohistochemistry and iron histochemistry in order to elucidate the pathogenesis of post‐traumatic epilepsy. The c‐fos‐immunopositive neurons were observed in a hippocampal formation, especially in the dentate gyrus and CA1 and CA2, in the vicinity of the iron injected cerebral cortex and amygdala only at 3 hours after the iron administration. Three days later after administration, several heavily positively iron staining cells and nerve fibers were observed around the injection site. In the cases of 3 weeks after administration, the large cavity and gliosis were characteristically observed.
Power-efficient resource allocation for QoS provisioning in underwater MIMO-OFDM acoustic cooperative wireless networks

In recent years, the multiple-input-multiple-output (MIMO), the orthogonal frequency division multiplexing (OFD- and the relay communication techniques have significantly improved the important performance of radio wireless communication networks. Due to its wide and critical applications, we can also apply these techniques into the underwater acoustic (UWA) wireless networks. In this paper, we propose the power-efficiency resource allocation scheme for tradeoff between the power consumption and quality of service (QoS) of multimedia applications in a relay-based underwater MIMO-OFDM acoustic cooperative wireless networks. Our objective is to efficiently minimize the total power/energy consumption while supporting the QoS-guaranteed services for multimedia applications over underwater MIMO-OFDM acoustic cooperative wireless networks. To achieve these goals, we propose a joint optimization of source and relay network transmit power with the QoS-constraint for the relay-based MIMO-OFDM underwater acoustic cooperative wireless networks. We conduct the extensive simulations to validate and evaluate our proposed scheme, showing its superiority over the other existing schemes.
Fractionally spaced decision feedback joint detection for multitone CDMA systems

In the present paper we consider a fractionally spaced decision feedback joint detector for multitone CDMA systems. We first derive the structure of the receiver for an MMSE criterion. Then we evaluate the BER achieved by this detector for BPSK modulation in steady-state conditions. We consider an asynchronous scenario where the signal of each user propagates over a two-path channel. The resistance of the detector against timing errors is studied and the resistance against a near-far scenario is also demonstrated.
Structurally enhanced latent semantic analysis for video object retrieval

The work presented in this paper aims at reducing the semantic gap between low level video features and semantic video contents. The proposed method for finding associations between segmented frame region characteristics relies on the strength of latent semantic analysis (LSA). Previous work, using colour histograms and Gabor features, have rapidly shown the potential of this approach but also uncovered some of its limitations. The use of structural information is necessary, yet rarely employed for such a task. This paper addresses two important issues: the first is to verify that using structural information does indeed improve information retrieval performances, while the second concerns the manner in which this additional information is integrated within the framework. Here, two methods are proposed using the structural information contained in object parts' topological arrangement. The first adds structural constraints indirectly to the LSA during the preprocessing of the video, while the other includes the structure directly within the LSA. Finally, retrieval results demonstrate that when the structure is added directly to the LSA the performance gain of combining visual (low level) and structural information is convincing.
Circulation des Chlamydiaceae en filières avicoles, exposition des professionnels et étude de la survie de Chlamydia psittaci

La chlamydiose aviaire, causee par la bacterie Chlamydia psittaci, represente un risque zoonotique important. L’infection chez l’animal est principalement asymptomatique, mais chez l’Homme elle peut entrainer des pneumopathies atypiques severes et causer la mort dans les cas les plus graves. Les personnes infectees sont principalement celles exposees regulierement a des oiseaux, particulierement dans le cadre professionnel. En France, de nombreux cas humains sont lies a une exposition a des canards Mulard, espece utilisee pour la production du foie gras. Afin d’evaluer la prevalence des Chlamydiaceae chez les volailles et de caracteriser les souches circulantes, des suivis ont ete realises a differents stades de l’elevage (couvoir, pre-gavage et gavage pour la filiere canard, et abattoirs impliques dans l’abattage de differentes especes aviaires). Des prelevements d’air et de poussieres ainsi que des suivis serologiques et biologiques de personnels volontaires ont ete effectues en parallele afin d’evaluer l’exposition des professionnels travaillant au contact des volailles. Des prelevements environnementaux ainsi que des essais in vitro visant a etudier la survie de C. psittaci ont ete realises afin de tenter de mieux caracteriser les voies de contamination des oiseaux, ce qui pourrait, a terme, permettre de maitriser le risque de contamination par C. psittaci chez l’animal et donc de reduire l’exposition des professionnels. Les resultats ont demontre une prevalence importance de C. psittaci chez le canard Mulard, au contraire des autres volailles qui hebergent tres majoritairement C. gallinacea. L’exposition des professionnels aux Chlamydia est reelle, tout au long du processus d’elevage des volailles, mais plus particulierement en elevages de canards Mulard et a l’abattoir, aussi il convient pour les professionnels de se proteger a chaque contact avec les animaux. L’hypothese d’une contamination environnementale des animaux se fait de plus en plus claire, avec notamment la mise en evidence d’un lien existant entre les procedures de nettoyage et desinfection et l’excretion des canards, la description de la survie de C. psittaci en dehors de tout hote vivant, ou encore la mise en evidence d’une possible survie de C. psittaci au sein d’A. castellanii. La mise au point de moyens de lutte efficaces permettant de reduire voire de supprimer l’excretion chez les volailles est egalement necessaire, dans le but de diminuer l’exposition des professionnels
Localization-based visual tracking with convolutional neural networks

This paper presents a novel framework for the visual tracking problem. This framework predicts the exact location of the object using a regression. In this work, we first select an approximate region based on object location in the previous frame and then predict the exact location of the object in the current frame by a deep convolutional network that its last layer replaced with a regression. The entire network gets updated due to the occurrence of various challenges during the video. We evaluate our work using 8 challenging benchmark video sequences and shows a significant improvement over state-of-the-art approaches.
Gastroschisis: International epidemiology and public health perspectives

Gastroschisis offers the intriguing epidemiological situation of a pandemic, strongly associated with very low maternal age. Identifying gastroschisis, and distinguishing it from the other abdominal wall defects, is theoretically easy but difficult in practice. The baseline birth prevalence of gastroschisis before the pandemic was approximately 1 in 50,000 births and has increased since between 10‐ and 20‐fold. In many populations worldwide, it is still increasing. Such increasing prevalence and the association with very low maternal age are well proven, but the interaction between these two findings remains unknown. Geographic gradients (decreasing prevalence from North to South) are clear in Continental Europe and suggestive in Britain and Ireland. Gastroschisis seems more frequent in Caucasians compared to African Blacks and Orientals, and in Northern compared to Southern Europeans. These observations indicate the need for investigating gene–environment interactions. Since the global human situation is marked by inequalities among as well as within countries, the medical care and public health impact of gastroschisis varies widely among regions and social strata. The postnatal benefits of prenatal diagnosis of gastroschisis include family awareness; adequate planning of delivery with alerted obstetrical, pediatric, and surgical staff; optimal risk categorization, and personalized protocol for action. The increasing prevalence of gastroschisis combined with improved medical techniques to reduce morbidity and mortality are also increasing the burden and costs of this anomaly on health systems. © 2008 Wiley‐Liss, Inc.
High prevalence of renal transplant recipients infected with more than one cytomegalovirus glycoprotein B genotype.

A prospective analysis of cytomegalovirus (CMV) glycoprotein B (gB) genotypes was conducted on 34 renal transplant recipients using peripheral blood leukocytes (PBLs) and urine specimens. The CMV gB genotypes were analyzed by polymerase chain reaction (PCR) followed by enzyme digestion. PBLs and urine samples showed almost equal proportions of the 4 known gB genotypes, as well as equal proportions of gB genotype mixtures. The gB genotypes 1, 2 and 3 were equally distributed in the patients. Twenty-four (70.6%) patients had more than one gB genotype during follow-up. There was no association of gB genotypes with the development of symptomatic CMV infection.
Design of a New Reduced Size Dual-Mode Microstrip Resonator Bandpass Filter for Modern Wireless Applications

In this paper, the design of a new compact size dual-mode microstrip resonator is presented as a candidate for use in modern wireless applications. The proposed resonator structure is a result of applying two reduction techniques to the conventional square patch dual-mode microstrip resonator. First, the edges of the conventional square patch have been replaced by first iteration Koch pre-fractal curves. The proposed resonator filter has been designed for ISM band applications, at 2.4 GHz, using a substrate with a relative dielectric constant of 10.8 and thickness of 1.27 mm. This has shown to result in dual-mode resonator with a side length of 16.05 mm, which represents a size reduction of about 24%, as compared with the conventional square patch resonator using the same substrate and designed at the same frequency. Moreover, the resonator size has been further reduced by inserting a crossed slot in the patch structure. The resulting microstrip patch dual-mode resonator has been found to possess a side length of about 11.55 mm, which represents a size reduction of about 61% as compared with the conventional square patch dual-mode resonator. Modeling and performance evaluation of the presented resonator structures have been carried out using a method of moments based IE3D SSD electromagnetic simulator from Mentor Graphics Corporation. Simulation results show that the proposed filter has acceptable return loss and transmission responses besides the miniaturized size gained. mode resonator, microwave resonator miniaturization, Koch fractal Dual :

Reactive Oxygen and Nitrogen Intermediates and Products from Polyamine Degradation Are Babesiacidal In Vitro a

Products released from activated macrophages have been demonstrated to have microbicidal activity against a variety of microorganisms. Reactive oxygen intermediates (ROI) and reactive nitrogen intermediates (RNI) have been shown to affect the induction of degenerate (crisis) forms of Plasmodium spp. Polyamines are degraded into acrolein which has also been shown to be toxic to Plasmodium spp. We have investigated the possibility that these products act similarly with Babesia bovis. Crisis forms of B. bovis developed in erythrocyte cultures after the introduction of supernatants containing ROI, RNI, and acrolein. Xanthine degradation by xanthine oxidase leads to the formation of superoxide anion, hydrogen peroxide, and hydroxyl radicals. The degradation in the presence of B. bovis was toxic to the parasite. The toxicity was partially reversed by the addition of the ROI scavenger catalase. However, H2O2 added directly had little effect, suggesting a role for the other ROI products. Spermine degradation by polyamine oxidase and direct addition of acrolein was toxic in a dose-dependent manner. Finally, spontaneous generation of nitric oxide from sodium nitroprusside or S-nitroso-N-acetyl-penicillamine was also toxic in a dose-dependent manner. These data lead us to suggest a role for activated macrophages in the primary immune response against B. bovis.

What Determines Video Game Use?

The present study explores the role of intentions, habits, and addictive tendencies in people's video game use. Although both habits and addictive tendencies may determine higher amounts of video game use, the present study examines whether the impact of habits and addictive tendencies on video game use may also be lower the less users intend to play (indicating a moderating role of intention). To test these assumptions, survey data were collected in two waves (N = 351), measuring causal factors in the first wave and outcomes (subsequent video game use) in the second. Results of mediation analyses reveal a positive impact of both habits and addictive tendencies on video game use that is partly affected by users' intentions. Furthermore, moderation analyses suggest that the impact of habits, but not of addictive tendencies, on video game use decreases, the less users intend to play. Taken together, these findings suggest that users' video game habits, addictive tendencies, and intentions jointly determine video game use.
Optimal Estimation in Wireless Sensor Networks With Energy Harvesting

In this paper, the source estimation problem is investigated in a wireless sensor network (WSN) with energy-harvesting (EH) nodes. We first consider a deterministic EH model where the amount of harvested energy at each node is known prior to transmissions. For such a model, we investigate the average mean-square-error (MSE) minimization problem over a finite horizon of multiple estimation periods and derive the optimal solution. Moreover, a more realistic stochastic EH model is considered, where only the current amount of harvested energy is known. The corresponding MSE minimization problem over an infinite horizon is formulated. The Lyapunov optimization technique is adopted to obtain a solution for the stochastic EH problem. Simulation results are conducted to validate the effectiveness of the proposed solutions for both the deterministic and stochastic EH models.
Dynamically and epigenetically coordinated GATA/ETS/SOX transcription factor expression is indispensable for endothelial cell differentiation

Abstract Although studies of the differentiation from mouse embryonic stem (ES) cells to vascular endothelial cells (ECs) provide an excellent model for investigating the molecular mechanisms underlying vascular development, temporal dynamics of gene expression and chromatin modifications have not been well studied. Herein, using transcriptomic and epigenomic analyses based on H3K4me3 and H3K27me3 modifications at a genome-wide scale, we analysed the EC differentiation steps from ES cells and crucial epigenetic modifications unique to ECs. We determined that Gata2, Fli1, Sox7 and Sox18 are master regulators of EC that are induced following expression of the haemangioblast commitment pioneer factor, Etv2. These master regulator gene loci were repressed by H3K27me3 throughout the mesoderm period but rapidly transitioned to histone modification switching from H3K27me3 to H3K4me3 after treatment with vascular endothelial growth factor. SiRNA knockdown experiments indicated that these regulators are indispensable not only for proper EC differentiation but also for blocking the commitment to other closely aligned lineages. Collectively, our detailed epigenetic analysis may provide an advanced model for understanding temporal regulation of chromatin signatures and resulting gene expression profiles during EC commitment. These studies may inform the future development of methods to stimulate the vascular endothelium for regenerative medicine.
Design of Built in Self Test Asynchronous Micropipeline using Double Edge Triggered D Flip Flop

Asynchronous micropipeline is a popular design style of building asynchronous circuits. This paper presents the novel idea of implementation of Built in Self Test (BIST) asynchronous micropipeline using Double Edge Triggered D Flip Flop(DETDFF). A two stage, 4 bit asynchronous micro pipeline incorporated with built in self test feature and operating in four modes namely normal mode, testing mode, Linear Feedback Shift register (LFSR) and Signature analyzer(SA) modes have been implemented using DETDFF. We had compared our proposed circuit with BIST asynchronous micropipeline designed using BILBO register by Petlin and Furber. We have implemented both the circuits in CMOS 0.13u and 0.18u Technology using T-spice and compared the performance in terms of power consumption and delay.
Intestinal alkaline phosphatase regulates protective surface microclimate pH in rat duodenum

Regulation of localized extracellular pH (pHo) maintains normal organ function. An alkaline microclimate overlying the duodenal enterocyte brush border protects the mucosa from luminal acid. We hypothesized that intestinal alkaline phosphatase (IAP) regulates pHo due to pH‐sensitive ATP hydrolysis as part of an ecto‐purinergic pH regulatory system, comprised of cell‐surface P2Y receptors and ATP‐stimulated duodenal bicarbonate secretion (DBS). To test this hypothesis, we measured DBS in a perfused rat duodenal loop, examining the effect of the competitive alkaline phosphatase inhibitor glycerol phosphate (GP), the ecto‐nucleoside triphosphate diphosphohydrolase inhibitor ARL67156, and exogenous nucleotides or P2 receptor agonists on DBS. Furthermore, we measured perfusate ATP concentration with a luciferin–luciferase bioassay. IAP inhibition increased DBS and luminal ATP output. Increased luminal ATP output was partially CFTR dependent, but was not due to cellular injury. Immunofluorescence localized the P2Y1 receptor to the brush border membrane of duodenal villi. The P2Y1 agonist 2‐methylthio‐ADP increased DBS, whereas the P2Y1 antagonist MRS2179 reduced ATP‐ or GP‐induced DBS. Acid perfusion augmented DBS and ATP release, further enhanced by the IAP inhibitor l‐cysteine, and reduced by the exogenous ATPase apyrase. Furthermore, MRS2179 or the highly selective P2Y1 antagonist MRS2500 co‐perfused with acid induced epithelial injury, suggesting that IAP/ATP/P2Y signalling protects the mucosa from acid injury. Increased DBS augments IAP activity presumably by raising pHo, increasing the rate of ATP degradation, decreasing ATP‐mediated DBS, forming a negative feedback loop. The duodenal epithelial brush border IAP–P2Y–HCO3− surface microclimate pH regulatory system effectively protects the mucosa from acid injury.
