Design of E slot rectangular microstrip slot antenna for WiMAX application

In this paper, a new design technique of microstrip patch antenna with E-slot and a-slot at the edge of the radiator for Worldwide Interoperability for Microwave Access (WiMAX) application is presented. The proposed microstrip patch antenna adopts the partial ground planes and Rogers Duroid 5880 substrate is used which is having low dielectric constant, thereby provides good bandwidth. Microstrip feedline technique is used to feed the antenna with 50Ω impedance. The proposed antenna has a compact size of 34 × 27 × 0.787 mm2 and with return loss of -18.6 dB at the lower and middle frequency range of WiMAX application. Using Ansoft HFSS the simulated results are nresented and evaluated with and without slit.
Analysis of a Soft Switching PWM Active Clamp Cuk Converter

A soft switching pulse-width modulation (PWM) Cuk converter with boost type of active clamp is proposed. Active clamp circuit can help the switching devices in the Cuk converter to be operated at zero voltage switching (ZVS) turn-on. Therefore this converter is suitable for high frequency operation to reduce the size of reactive components. The clamp capacitor and auxiliary switch are connected in parallel with the primary switch. When main switch is turned off, the positive inductor current will flow through the anti-parallel diode of auxiliary switch. At this instant, the auxiliary switch can turn on at ZVS. On the other hand, the resonance between the resonant inductor and output capacitor of main switch will create a ZVS condition for main switch. The principle of operation, system analysis, and design consideration are presented in this paper. Experimental results for a laboratory prototype rated at 400 W, input voltage of 150 V~300 V, output voltage of 200 V, and operating at 105 kHz are given to demonstrate the effectiveness of the proposed converter.
hypertension in Dahl S rats with a 1.37 Mbp genomic region protective of Characterization of biological pathways associated

Summary The present study utilized 13 overlapping congenic strainsand identiﬁed by exclusion mapping a 1.37 Mbp region on chr13(positions80.92to82.29MbpintheRn5genomeassembly)that signiﬁcantly inﬂuences the MAP in SS rats fed an HS diet.After DNA sequencing to ﬁll gaps in the reference sequence inthis region, ﬁve genes were identiﬁed ( Rfwd2, Astn1, Fam5b,Pappa2 , and Tnr ). Of these ﬁve genes, Rfwd2 was the moststrongly expressed in the renal outer medulla. The Bayesiananalyses indicated several genes that may connect Rfwd2 topathways related to blood pressure. As summarized in theschematic in Fig. 6, nine genes in the 19 blood pressure-relatedpathways exhibited very high partial correlations with Rfwd2 . Four of these genes that were interdependent with Rfwd2 exhibited signiﬁcant differences in mRNA abundance betweenSS and salt-resistant congenic rats. Plausible mediators linking Rfwd2 to mechanisms of arterial blood pressure regulation asindicated by partial correlation values include:
One microphone speech separaction with deep belief network

In this paper, we proposed a novel method for speech separation under one-microphone input. The method employs the deep belief networks to build the speech magnitude estimator, which provides a soft mask for extracting the desired speech from the input signal mixed with interference signals. The new approach has been evaluated on mixture speech data and the results demonstrated its efficiency.
Large-Scale Design Optimization of PM Machines Over a Target Operating Cycle

A large-scale finite element model-based design optimization algorithm is developed for improving the drive-cycle efficiency of permanent magnet (PM) synchronous machines with wide operating ranges such as those used in traction propulsion motors. The load operating cycle is efficiently modeled by using a systematic k-means clustering method to identify the operating points representing the high-energy-throughput zones in the torque-speed plane. The machine performance is evaluated over these cyclic representative points using a recently introduced computationally efficient finite element analysis, which is upgraded to include both constant torque and field-weakening operations in the evaluation of the machine performance metrics. In contrast with the common practice, which aims at enhancing the rated performance, the entire range of operation is considered in the present design optimization method. Practical operational constraints imposed by the voltage and current limits of the motor-drive system, excessive PM demagnetization, and torque ripple are accounted for during the optimization process. The convergence to the optimal design solutions is expedited by utilizing a new stochastic optimizer. The developed design algorithm is applicable to any configuration of sinewave-drive PM and synchronous reluctance motors over any conceivable load profile. Its effectiveness is demonstrated by optimizing the well-established benchmark design represented by the Toyota Prius Gen. 2 interior PM motor configuration over a compound operating cycle consisting of common U.S. driving schedules. Multiphysics electromagnetic, thermal, and mechanical performance of the optimized design solutions is discussed in a postdesign optimization stage.
The buried Balmer-edge signatures from quasars

In our previous paper, we reported the detection of a Balmer edge absorption feature in the polarized flux of one quasar (Ton 202). We have now found similar Balmer edge features in the polarized flux of four more quasars (4C09.72, 3C95, B2 1208+32, 3C323.1), and possibly a few more, out of 14 newly observed with the Very Large Telescope and the Keck Telescope. In addition, we also re-observed Ton 202, but we did not detect such a dramatic feature, apparently due to polarization variability (the two observations are 1 yr apart). The polarization measurements of some quasars are affected by an interstellar polarization in our Galaxy, but the measurements have been corrected for this effect reasonably well. As the broad emission lines are essentially unpolarized and the polarization is confined only to the continuum in the five quasars including Ton 202 in both epochs, the polarized flux is considered to originate interior to the broad emission-line region. The Balmer edge feature seen in the polarized flux is most simply interpreted as an intrinsic spectral feature of the quasar ultraviolet/optical continuum, or the ‘Big Blue Bump’ emission. In this case, the edge feature seen in absorption indeed indicates the thermal and optically thick nature of the continuum emitted. However, we also discuss other possible interpretations.
Acoustic modeling for spontaneous speech recognition using syllable dependent models

This paper proposes a syllable context dependent model for spontaneous speech recognition. It is generally assumed that, since spontaneous speech is greatly affected by coarticulation, an acoustic model featuring a longer range phonemic context is required to achieve a high degree of recognition accuracy. This motivated the authors to investigate a tri-syllable model that takes differences in the preceding and succeeding syllables into account. Since Japanese syllables consist of either a single vowel or a consonant and vowel combination, a tri-syllable model always takes the preceding and succeeding vowels that are the primary factors in coarticulation into account. A tri-syllable model is thus capable of efﬁciently representing coarticulation. The tri-syllable model was trained using sponta-neous speech; then, the effectiveness of continuous syllable recognition and statistical language model-based continuous word recognition were evaluated. Compared to a regular triphone model without state sharing, it was found that the correct syllable accuracy of the continuous syllable recognition improved from 64.9% to 66.3%. The word recognition accuracy for the statistical language model-based continuous word recognition improved from 88.4% to 89.2%.
A Review: Detecting Alterations of Brain Connectivity in Schizophrenia basedon Structural MRI

Schizophrenia is a common psychiatric disease with brain connectivity changed. Nowadays brain network has become an effective tool to detect the abnormal brain connectivity in patients. Compared with studies focused on functional and white matter connectivity, the research of grey matter connectivity is relatively less and should be paid more attention. The primary approach of grey matter connectivity analysis is based on brain network constructed from structural MRI (sMRI). There are several morphometric features such as cortical thickness, volume, and curvature etc. Which could be used for sMRI brain network construction? This review briefly introduced sMRI brain network construction and analysis, presenting the most frequently used morphometric features with their effectiveness in schizophrenia, highlighting the application of sMRI brain network in schizophrenia, and finally estimated its potential value.
Romidepsin-induced HIV-1 viremia during effective antiretroviral therapy contains identical viral sequences with few deleterious mutations

Objective: To investigate the origin of the HIV-1 viremia induced by the latency-reversing agent romidepsin. Design: Six individuals on suppressive antiretroviral therapy received romidepsin administered intravenously once weekly for 3 consecutive weeks. CD4+ T cells were obtained at baseline, following the second and third romidepsin infusion, and 10 weeks after the final romidepsin treatment. Plasma samples were collected 24 and 72 h after romidepsin infusions. Methods: Single-genome sequencing of the env and p24-RT region was used to genetically characterize the virus from proviral DNA, the transcribed cell-associated RNA and the plasma RNA pool. Results: In three of six participants with available plasma samples we identified plasma HIV-1 RNA sequences that were identical to DNA and/or cell-associated RNA sequences from peripheral blood CD4+ T cells. In two participants, plasma RNA sequences contained expansions of identical sequences, corresponding to 62 and 100% of the total sequences, respectively. Plasma HIV-1 RNA had very low amounts of defective viruses compared to cell-associated RNA (odds ratio 20.85, P < 0.001) and to DNA (odds ratio 7.07, P = 0.011) during romidepsin therapy. Conclusions: Romidepsin induced transcription from proviruses in peripheral blood cells, which contributed to viremia in patients on suppressive therapy. The intermingling of these cell-associated HIV-1 RNA with DNA sequences indicates transcription from a diverse range of proviruses, but the expansions of identical viral plasma sequences with few defects indicate that the romidepsin-induced viremia arises from intact proviruses with highly similar or identical genetic backgrounds.
Elastic paging

We study a generalization of the classic paging problem where memory capacity can vary over time - a property of many modern computing realities, from cloud computing to multi-core and energy-optimized processors. We show that good performance in the "classic" case provides no performance guarantees when memory capacity fluctuates: roughly speaking, moving from static to dynamic capacity can mean the difference between optimality within a factor 2 in space, time and energy, and suboptimality by an arbitrarily large factor. Surprisingly, several classic paging algorithms still perform remarkably well, maintaining that factor 2 optimality even if faced with adversarial capacity fluctuations - without taking those fluctuations into explicit account!
Medication-related Self-management Behaviors among Arthritis Patients: Does Attentional Coping Style Matter?

Objective: The aim of this study was to investigate the relationship between the attentional coping styles (monitoring and blunting) of rheumatoid arthritis (RA) and osteoarthritis (OA) patients and: (a) receipt of medication information; (b) receipt of conflicting medication information; (c) ambiguity aversion; (d) medication-related discussions with doctors and spouse/partners; and (e) medication adherence. Method: A sample of 328 adults with a self-reported diagnosis of arthritis (RA n=159; OA n=149) completed an Internet-based survey. Coping style was assessed using the validated short version of the Miller Behavioral Style Scale. Measures related to aspects of medication information receipt and discussion and validated measures of ambiguity aversion and medication adherence (Vasculitis Self-Management Survey) were collected. Pearson correlation coefficients, ANOVA, independent samples t-tests and multiple regression models were used to assess associations between coping style and the other variables of interest. Results: Arthritis patients in our sample were more likely to be high monitors (50%) than high blunters (36%). Among RA patients, increased information-receipt was significantly associated with decreased monitoring (b = -1.06, p = .001). Among OA patients, increased information-receipt was significantly associated with increased blunting (b = .60, p = .02). Conclusion: In our sample of patients with arthritis, attentional coping style is not in accordance with the characteristic patterns outlined in the acute and chronic disease coping literature.

24 Nanoelectromechanical Systems – Experiments andModeling

Nanoelectromechanical systems (NEMS) are made of electromechanical devices that have critical dimensions from hundreds down to a few nanometers. By exploring nanoscale effects, NEMS present interesting and unique characteristics, which deviate greatly from their predecessor microelectromechanical systems (MEMS). For instance, NEMS-based devices can have fundamental frequencies in the microwave range (approximately 100 GHz) [1]; mechanical quality factors in the tens of thousands, meaning low energy dissipation; active mass in the femtogram range [2]; force sensitivity at the attonewton level [3]; mass sensitivity up to attogram [4] and subattogram [5] levels; heat capacities far below a “yoctocalorie” [6]; power consumption in the order of 10 aW [7]; and extremely high integration levels, approaching 1012 elements per square centimeter [1]. All these distinguished properties of NEMS devices pave the way for applications such as force sensors, chemical sensors, biological sensors, and ultrahigh frequency resonators. The interesting properties of the NEMS devices typically arise from the behavior of the active parts, which, in most cases, are in the form of cantilevers or doubly clamped beams with dimensions at the nanometer scale. The materials for these active components include silicon and silicon carbide, carbon nanotubes (CNTs), gold, and platinum, to name a few. Silicon has been the basic material for integrated circuit technology and MEMS during the past few decades, and is widely used to build NEMS as well. Figure 24.1 is a scanning electron microscopy (SEM) image of a double-clamped resonator fabricated from a bulk, single-crystal silicon substrate [8]. However, ultrasmall silicon-based NEMS fail to achieve desired high quality factors owing to the dominance of surface effects, such as surface oxidation
Idiosyncratic Sentiments and Coordination Failures

Coordination models have been used in macroeconomics to study a variety of crises phenomena. It is well understood that, in these models, aggregate fluctuations can be purely self-fulfilling. In this paper I highlight that cross-sectional heterogeneity in expectations regarding the endogenous prospects of the economy can also emerge as a purely self-fulfilling equilibrium property. This in turn leads to some intriguing positive and normative implications: (i) It can rationalize idiosyncratic investor sentiment. (ii) It can be the source of significant heterogeneity in real and financial investment choices, even in the absence of any heterogeneity in individual characteristics or information about all economic fundamentals, and despite the presence of a strong incentive to coordinate on the same course of action. (iii) It can sustain rich fluctuations in aggregate investment and asset prices, including fluctuations that are smoother than those often associated with multiple-equilibria models of crises. (iv) It can capture the idea that investors learn slowly how to coordinate on a certain course of action. (v) It can boost welfare. (vi) It can render apparent coordination failures evidence of improved efficiency. *An earlier version was entitled "Private Sunspots and Idiosyncratic Investor Sentiment. "
Herpes simplex virus and the lexicon of latency and reactivation: a call for defining terms and building an integrated collective framework

The field of herpes simplex virus (HSV) latency and reactivation has been marked by controversy, which is not unexpected considering the complexities of the biology involved. While controversy is an important tool for digging to the bottom of difficult issues, we propose that unproductive conflict in the field arises in part from poorly defined terminology and the need for a collective framework. The uses of advanced global molecular and next-generation sequencing approaches and an increasing array of in vitro model systems have provided new molecular-level insights into HSV latency and reactivation, with the promise of expanding our concepts of these processes. However, our current framework and language are inadequate to effectively integrate new data streams into the established theories. In this brief perspective, we look back into the past to examine when and how the lexicon of HSV latency and reactivation arose in the literature and its evolution. We propose to open a dialogue among investigators for the purpose of updating and clearly defining terms used to describe these processes and to build a collective integrated framework to move our field forward.
A 3-year causative study of pompholyx in 120 patients.

OBJECTIVE To assess the relative frequency of the different causes of pompholyx evoked in the literature. DESIGN Prospective survey. SETTING Clinical outpatient setting. PATIENTS A total of 120 consecutive patients with pompholyx referred to our department from 2000 through 2003. MAIN OUTCOME MEASURES Systematic investigation of different causes of pompholyx: fungal intertrigo, hyperhidrosis, atopy, contact eczema, and internal reactions with systematic provocation tests to metals, balsam of Peru, and food allergen when suspected. RESULTS The present study found the following causes of pompholyx in the 120 patients: mycosis (10.0%); allergic contact pompholyx (67.5%), with cosmetic and hygiene products as the main factor (31.7%), followed by metals (16.7%); and internal reactivation from drug, food, or haptenic (nickel) origin (6.7%). The remaining 15.0% of patients were classified as idiopathic patients, but all were atopic. (Percentages do not total 100 because of rounding.) CONCLUSIONS Our data confirm the existence of reactional pompholyx to interdigital-plantar intertrigos and endogenous reactions to metals or other allergens, but they mainly point at the unexpected importance of a so-called contact pompholyx in which cosmetic and hygiene products play a preponderant role compared with metals. The great frequency of atopic conditions, even if idiopathic pompholyx is not inferred as an equivalent of atopy, should lead to further causative investigations before undertaking more expensive or extensive treatments of refractory pompholyx.
Managing a Multilingual Treebank Project

This paper describes the work process for a Multilingual Treebank Annotation Project executed for Google and coordinated by a small core team supervising the linguistic work conducted by linguists working online in various locations across the globe. The task is to review an output of a dependency-syntactic parser, including the POS types, dependency types and relations between the tokens, fix errors in output and prepare the data to a shape that can be used for further training of the parser engine. In this paper we focus on the implemented Quality Assurance processes and methodology that are used to monitor the output of the four language teams engaged in the project. On the quantitative side we monitor the throughput to spot any issues in particular language that would require intervention or improving the process. This is combined with a qualitative analysis that is performed primarily by comparing the incoming parsed data, the reviewed data after the first round and after the final crossreview using snapshots to compile and compare statistics. In addition, the possible inconsistencies in the annotations are checked and corrected automatically, where possible, in appropriate stages of the process to minimize the manual work.
A Kaleidoscopic Study of Pricing Performance of Stochastic Volatility Option Pricing Models: Evidence from Recent Indian Economic Turbulence

A whole host of researchers have modeled volatility as a non-constant stochastic process, based on the principle that volatility follows a stochastic process whose parameters are not directly observable in the market. The objective of this research paper is to empirically investigate the forecasting performance of three most dominant models of this species namely, Hull-White (1988), Heston�s (1993), and Heston-Nandi GARCH (2000) option pricing model. These three models have been collaterally compared and contrasted against Black-Scholes and market for pricing S&P CNX Nifty 50 index option of India. The Hull-White model not only warrants a range of stochastic volatility specifications but also incorporates correlation of volatility of asset return and its price changes. The closed form Heston�s (1993) model explicitly and elaborately communicates non-lognormal distribution of the assets return, leverage effect, and mean-reverting property of volatility. The model of Heston-Nandi, also in closed form, successfully incorporates variance of asset returns as a range of GARCH process. It strongly permits correlation between returns of the spot asset and variance and also technically accepts multiple lags in the dynamics of the GARCH process. To decide, determine, and delineate the effectiveness of stochastic models against the Black-Scholes and market, the current paper adopts a structured approach of relative error price, viz., percentage mean error (PME) and mean absolute percentage error (MAPE). The most turbulent period of the Indian economy � January 1, 2008 to December 31, 2008 — was considered appropriate for testiing the suggested model. It was a testing time for the Indian economy as well as a critical period questioning the sustainability of all financial products/models and challenging their fundamental platform depicted as equity market. How to safeguard investors� faith and at least protect their investments if not multiply returns in the face of such financial hardships remained a burning question for all thinkers and experts on the subject. Data pertaining to the specific period of such drastic disturbance was analysed with the help of the proposed models. After rigorous churning of specific data taken across various models, the Heston model was found to outperform and surpass other models.
