The three-dimensional electromagnetic simulation analysis of power transmission of loosely coupled transformer based on ANSYS

The loosely coupled transformer (also called separable transformer) is the key component of inductive coupled power transfer (ICPT) system. Its coupling coefficient is very low which limits transmission efficiency of ICPT system. This paper describes the principle of ICPT system, and utilizes ANSYS software to simulate magnetic field of loosely coupled transformer. Three-dimensional simulation can show the core structure more clearly, and makes the results of analysis more accurate. Through quantitative analyzing the distributions of magnetic field intensity, magnetic flux density of loosely coupled transformer and the secondary-side load electromotive force, the paper draws a conclusion that the key technical parameters, such as operating frequency, air gap, core thickness and magnetic core position shift etc have significant impact on the coupling coefficient of the loosely coupled transformer. Furthermore, the transmission efficiency is improved during the resonance after adding capacitors to primary side in the circuit. The simulation analysis of the relationship between the key parameters and the coupling coefficient will be very helpful for the development of loosely coupled transformer and subsequent experiments.
Identifying protective antigens of Staphylococcus aureus, a pathogen that suppresses host immune responses

Staphylococcus aureus infections result in abscesses as well as septicemia. Even with therapy, abscesses can persist or even reoccur, as staphylococcal infections fail to induce protective immune responses. Here, we show that prior infection with certain attenuated strains may elicit protective immunity. A closer examination reveals that protection correlates with antibody responses elicited on exposure to particular attenuated variants. Linear regression analysis was used to compare reduction in staphylococcal disease and antibody responses to infection with wild‐type and attenuated variants. This analysis identified protective antigens that, when tested as vaccines in mice, elicited disease protection. Protection afforded by attenuated strains correlates in part with the ability of Staphylococcus aureus to modulate B cell responses via protein A (spa encoded). We designate this approach “genetic vaccinology,” since it exploits genetic variants to draw a correlation between disease protection and humoral immune responses for the deduction of vaccine antigens. Genetic vaccinology is particularly useful for microbes that do not elicit natural protective immunity during infection. —Kim, H. K. , Kim, H. ‐Y. , Schneewind, O. , Missiakas, D.

Behavioral Consistency and Inconsistency in the Resolution of Goal Conflict

During the course of a day, consumers experience choices that involve goal conflict (e.g., eat tasty vs. healthy food, recreate vs. work, relax vs. act). In some cases, an initial behavior is followed by a similar behavior. In other cases, an initial behavior is followed by an opposing behavior. We posit that a passive guidance system can nonconsciously guide behavior when there is goal conflict and, hence, determine whether a sequence of behaviors will be consistent or inconsistent. The passive guidance system is sensitive to whether a current behavior sustains goal activation and encourages similar future behaviors or results in goal achievement and encourages dissimilar future behaviors. Eight experiments provide evidence for this passive guidance system.
Blind Recursive Subspace-Based Identification of Time-Varying Wideband MIMO Channels

We present a blind recursive algorithm for tracking rapidly time-varying wireless channels in precoded multiple-input-multiple-output (MIMO) orthogonal frequency-division multiplexing (OFDM) systems. Subspace-based tracking is normally considered for slowly time-varying channels only. Due to the frequency correlation of the wireless channels, the proposed scheme can collect data not only from the time but from the frequency domain as well to speed up the update of the required second-order statistics. After each such update, the subspace information is recomputed using the orthogonal iteration, and then, a new channel estimate is obtained. We also investigate choices of precoder in terms of the tradeoff between the symbol recovery capability and the channel estimation performance and demonstrate the convergence properties of our approach. The proposed algorithm is evaluated in a Third-Generation Partnership Project (3GPP) Spatial Channel Model suburban macro scenario, in which a mobile station is allowed to move in any direction with a speed up to 100 km/h, corresponding to a maximum Doppler shift of about 230 Hz in this case. Numerical experiments show that the normalized mean square error of the channel estimates converges to a level of -30 dB within less than five OFDM symbols when the signal-to-noise ratio (SNR) (per symbol) is ≥ 20 dB.
Sentence extraction-based presentation summarization techniques and evaluation metrics

This paper presents automatic speech summarization techniques and its evaluation metrics, focusing on sentence extraction-based summarization methods for making abstracts from spontaneous presentations. Since humans tend to summarize presentations by extracting important sentences from introduction and conclusion parts, this paper proposes a method using sentence location. Experimental results show that the proposed method significantly improves automatic speech summarization performance for the condition of 10% summarization ratio. Results of correlation analysis between subjective and objective evaluation scores confirm that objective evaluation metrics, including summarization accuracy, sentence F-measure and ROUGE-N, are effective for evaluating summarization techniques.

BURROWING OWL (ATHENE CUNICULARIA) POPULATION GENETICS: A COMPARISON OF NORTH AMERICAN FORMS AND MIGRATORY HABITS

Abstract We assessed the effects of range disjunction, migratory habit, coloniality, and habitat structure on the genetic differentiation of North American Burrowing Owl (Athene cunicularia) populations. Burrowing Owls in North America comprise two forms or subspecies: A. c. floridana in Florida, separated by ∼1,500 km from the western form, A. c. hypugaea, which ranges from Texas to California and north to southern Canada. Burrowing Owls tend to be loosely colonial, and both the Florida populations and southerly populations of A. c. hypugaea from California to Texas are nonmigratory. To assess genetic structure, we examined 201 individuals from nine western and six Florida populations at seven highly variable microsatellite DNA loci. Mean gene diversity (Hexp) was higher in the west than in Florida (0.539 and 0.341, respectively; P < 0.05). Populations within subspecies were essentially panmictic (A. c. floridana: θ = 0.038, ρ = 0.014; A. c. hypugaea: θ = 0.014, ρ = 0.009) and even genetic differentiation across subspecies was modest (θ = 0.051, ρ = 0.014). Nevertheless, the western and Florida forms were easily distinguished by any of several criteria, such as allelic absences in Florida, assignment tests, and well-supported branches on the inferred phylogenetic tree. Genetic differentiation was at least twice as great in resident Florida (θ = 0.038) and California (θ = 0.021) populations as in migratory western populations (θ = 0.012), though 95% confidence intervals of theta estimates overlapped. We found no evidence of a genetic bottleneck that would result in evolutionary disequilibrium within subspecies. In the west, high observed heterozygosity values and evidence of gene flow suggest that population declines and patchy habitat, which currently imperil this species throughout much of its range, have not led to inbreeding or biologically meaningful genetic differentiation among the sampled populations.
Follicular lymphoma: prognostic factors for response and survival.

One hundred forty-eight patients with newly diagnosed follicular lymphoma were treated over a 12-year period. Twenty-two patients received radiotherapy for stage I and II disease, followed by adjuvant chemotherapy in 14 patients. One hundred thirteen were treated at presentation with short courses of chemotherapy, most often with single-agent chlorambucil for bulky stage II and stages III and IV disease. Thirteen patients were managed expectantly until there was evidence of disease progression. The median survival was 9 years. Patients treated with radiotherapy for stage I and II disease had an 83% relapse-free survival, but those with bulky stage II or stages III and IV disease treated with chemotherapy pursued a remitting and relapsing course with a 70% response rate at initial and subsequent retreatments, but a median duration of remission of 4 years in stage III and 1 year in stage IV disease (P = .041). Patients were observed in relapse and retreatment was administered as appropriate, once every 33 months on average. Poor prognosis patients could be identified by a combination of the presentation characteristics: B symptoms, hepatosplenomegaly, anemia, and abnormal liver function. These factors predicted a poor response to treatment and correlated with a short survival. Histologic subgroups were not associated with differences in survival, but transformation to a diffuse high-grade lymphoma was observed in 23 of the 72 patients (32%) at risk, with a median follow-up of 6 years and 6 months, and was associated with a very poor prognosis. The present treatment strategy has proved successful for most patients with localized disease and those older patients with indolent small volume disseminated follicular lymphoma. New approaches are being investigated for the younger poor prognosis patients.
Prevention and Reversal of Premature Endothelial Cell Senescence and Vasculopathy in Obesity-Induced Diabetes by Ebselen

Abstract— Although the accelerated atherosclerosis and premature aging of the cardiovascular system in patients with metabolic syndrome have been appreciated, the mechanisms of their development and potential therapeutic interventions remain unresolved. Our previous studies implicated advanced glycosylation end products in development of premature senescence preventable with a peroxynitrite scavenger, ebselen. Therefore, the effect of ebselen on endothelial senescence and vasculopathy in a model of metabolic syndrome—Zucker diabetic rats (ZDF)—was investigated. Ebselen decreased the abundance of 3-nitrotyrosine–modified proteins in ZDF rats. A 6-fold increase in the number of senescent endothelial cells in 22-week-old ZDF was prevented by ebselen. Development of vasculopathy, as collectively judged by the acetylcholine-induced vasorelaxation, NO production, angiogenic competence, and number of circulating microparticles, was almost completely prevented when ebselen was administered from 8 to 22 weeks and partially reversed when the treatment interval was 13 to 22 weeks. In conclusion, premature senescence of endothelial cells is progressively rampant in ZDF rats and is associated with the signs of severe vasculopathy. In addition, prevention of premature senescence of vascular endothelium through controlled decrease in nitrotyrosine formation was chronologically associated with the amelioration of vasculopathy, lending support to the idea of the pathogenetic role of premature senescence of endothelial cells in diabetic macrovasculopathy.
A Comparison of Alternative Audit Sources for Web Server Attack Detection

Most intrusion detection systems available today are using a single audit source for detecting all attacks, even though attacks have distinct manifestations in different parts of the system. In this paper we carry out a theoretical investigation of the role of the audit source for the detection capability of the intrusion detection system (IDS). Concentrating on web server attacks, we examine the attack manifestations available to intrusion detection systems at different abstraction layers, including a network-based IDS, an application-based IDS, and finally a host-based IDS. Our findings include that attacks indeed have different manifestations depending on the audit source used. Some audit sources may lack any manifestation for certain attacks, and, in other cases contain only events that are indirectly connected to the attack in question. This, in turn, affects the reliability of the attack detection if the intrusion detection system uses only a single audit source for collecting security-relevant events. Hence, we conclude that using a multisource detection model increases the probability of detecting a range of attacks directed toward the web server. We also note that this model should account for the detection quality of each attack / audit stream to be able to rank alerts. Keywords: intrusion detection, attack manifestations
Dickens and Darwin

This dissertation examines how Charles Dickensrs last completed novels, which appeared after the publication of Charles Darwinrs The Origin of Species (1859), process Victorian anxieties about evolutionary origins and connections. I argue that Dickensrs thematic work with origins and identitymspecifically in Great Expectations (1860-61) and Our Mutual Friend (1864n65)multimately transcends the epistemological dislocations of Darwinism through an affirmation of selfndetermination and development over biological determination and origins. I examine how this is registered most powerfully in the novelsr emphasis on the liberatory and redemptive nature of self-narration and narrative fantasy. Furthermore, I read this aesthetic assertion as Dickensrs developing response to Darwinian evolutionary theory and a bridge between the social commentary of his last two completed novels. This aesthetic counterpositioning demonstrates how Dickensrs engagement with Darwinian science was complex and richly contradictory. I begin by summarizing and synthesizing Goldie Morgentalerrs and Anny Sadrinrs key work on issues of heredity and parentage in Dickensrs oeuvre. As Morgentaler and Sadrin have argued, Dickensrs work before 1859 primarily articulates a deterministic vision of cohesion and continuity in personal and social identity. Dickensrs treatment of self-formation, however, becomes increasingly critical of hereditary determinants and undergoes a radical unraveling in his postn Origin work. Building on Morgentalerrs and Sadrinrs work, among others, I argue that Great Expectations is ultimately unable to harmonize the deterministic tenets of evolutionary theory with the liberatory desires that underwrite any act of selfnnarration. Retrospective narration becomes a site for remaking origins and identity through the fruitful distortions of storytelling. Dickensrs next and last finished novel, Our Mutual Friend, extends and heightens this work. I present an extended reading and recontextualization of the lengthy soliloquy that bisects the bookmin which the central character hijacks the narrative authority of the novelrs thirdnperson omniscient narrator and seeks to remake himself through a conspicuous act of selfnnarration. The Harmon soliloquy grapples with issues of origin and predestination and privileges even more emphatically the self-germinating potential of the individual over hereditary and environmental determinants.
Contingent Attentional Capture

Four experiments address the degree of top-down selectivity in attention capture by feature singletons through manipulations of the spatial relationship and featural similarity of target and distractor singletons in a modified spatial cuing paradigm. Contrary to previous studies, all four experiments show that when searching for a singleton target, an irrelevant featural singleton captures attention only when defined by the same feature value as the target. Experiments 2, 3, and 4 provide a potential explanation for this empirical discrepancy by showing that irrelevant singletons can produce distraction effects that are independent of shifts of spatial attention. The results further support the notion that attentional capture is contingent on top-down attention control settings but indicates that such settings can be instantiated at the level of feature values.
Energy and latency analysis for in-network computation with compressive sensing in wireless sensor networks

In this paper, we study data gathering with compressive sensing from the perspective of in-network computation in random networks, in which n nodes are uniformly and independently deployed in a unit square area. We formulate the problem of data gathering to compute multiround random linear function. We study the performance of in-network computation with compressive sensing in terms of energy consumption and latency in centralized and distributed fashions. For the centralized approach, we propose a tree-based protocol for computing multiround random linear function. The complexity of computation shows that the proposed protocol can save energy and reduce latency by a factor of Θ(√(n/log n)) for data gathering comparing with the traditional approach, respectively. For the distributed approach, we propose a gossip-based approach and study the performance of energy and latency through theoretical analysis. We show that our approach needs fewer transmissions than the scheme using randomized gossip.
Patient's rationale: Patient Knowledge retrieval from health forums

Online health forums are areas of exchange where patients, on condition of anonymity, can speak freely on their personal experiences. These resources are a gold mine for health professionals—giving them access to patient to patient, patient to health professional and even health professional to health professional exchanges. In this study, we used text mining techniques to analyse health forums in order to extract emotions (e.g., joy, anger, surprise, etc.) expressed by patients. After a study of real messages, we demonstrate the difficulty of manual annotation due to the low level of agreement between humans. We propose a method to identify the polarity of a message and extract one or several emotions. This method was validated on a substantial real dataset.
Fingerprint characteristic extraction by Ridge Orientation: an Approach for a Supervised Contactless Biometric System,

Fingerprints are the most widely used human characteristics for the purpose of people identification. However, touchbased fingerprint systems have some drawbacks due to skin elasticity, inconsistent finger placement, contact pressure, small sensing area, environment conditions and sensor noise. In this paper, we present a contactless fingerprint system based on a supervised contactless image acquisition and a ridge minutiae extraction method based on orientation computation. The fingerprint image acquisition method requires only an ordinary camera. The ridge orientation characteristic extraction is based on a double windowing of the ridge ending points and a single windowing of the ridge bifurcation points.
Identification and reconstruction of complex weld geometry based on modified entropy

In this paper, a modified entropy-based algorithm is proposed for identification and reconstruction of a complex weld geometry. The edge of the weld geometry is identified based on minimizing a modified entropy-type cost function, and the weld geometry is reconstructed based on the detected edge. In addition, the volume of the weld geometry is computed using the point cloud samples of the identified weld geometry, and the effects of Gaussian noise are also considered. Our simulation results using the proposed reconstruction algorithm demonstrate efficient identification and reconstruction of a complex weld geometry in the presence of Gaussian noise.
Serverless Network File Systems

The paper presents a design for serverless network file system that can dynamically distribute control processing, data storage and caching among a set of cooperating workstations. The aim is to improve performance, scalability and availablility of such a peer-based distributed system. The approach adopted in this paper is to build a monolithic system that handles all aspects of storage, caching, data layout and recovery. This is in contrast to the technique used by later distributed file systems such as Petal and Frangipani, which have a two-layer structure in order to reduce the complexity associated with building a single monolithic system.
Workplace participatory practices: Conceptualising workplaces as learning environments

Arguing against a concept of learning as only a formal process occurring in explicitly educational settings like schools, the paper proposes a conception of the workplace as a learning environment focusing on the interaction between the affordances and constraints of the social setting, on the one hand, and the agency and biography of the individual participant, on the other. Workplaces impose certain expectations and norms in the interest of their own continuity and survival, and in the interest of certain participants; but learners also choose to act in certain ways dependent on their own preferences and goals. Thus, the workplace as a learning environment must be understood as a complex negotiation about knowledge‐use, roles and processes – essentially as a question of the learner's participation in situated work activities.
Using Sequence Data To Infer the Antigenicity of Influenza Virus

ABSTRACT The efficacy of current influenza vaccines requires a close antigenic match between circulating and vaccine strains. As such, timely identification of emerging influenza virus antigenic variants is central to the success of influenza vaccination programs. Empirical methods to determine influenza virus antigenic properties are time-consuming and mid-throughput and require live viruses. Here, we present a novel, experimentally validated, computational method for determining influenza virus antigenicity on the basis of hemagglutinin (HA) sequence. This method integrates a bootstrapped ridge regression with antigenic mapping to quantify antigenic distances by using influenza HA1 sequences. Our method was applied to H3N2 seasonal influenza viruses and identified the 13 previously recognized H3N2 antigenic clusters and the antigenic drift event of 2009 that led to a change of the H3N2 vaccine strain. IMPORTANCE This report supplies a novel method for quantifying antigenic distance and identifying antigenic variants using sequences alone. This method will be useful in influenza vaccine strain selection by significantly reducing the human labor efforts for serological characterization and will increase the likelihood of correct influenza vaccine candidate selection.
