Gender differences of heart rate variability in healthy volunteers.

OBJECTIVE To identify the basic values of heart rate variability in Pakistani population and to verify our hypothesis that there are gender differences in cardiovascular autonomic modulation. METHODS The descriptive cross sectional study based on convenience probability sampling was conducted at Armed Forces Institute of Cardiology/National Institute of Heart Diseases (AFIC/NIHD) Pakistan. The duration of the study was from December 2009 to July 2010. It involved 24-hour holter monitoring of 45 healthy individuals using holter electrocardiography (ECG) recorder. Heart rate variability was analysed in time (SDNN, SDANN, SDNNi, rMSSD, pNN50) and frequency domains (power, VLF, LF, and HF). RESULTS The time domain indices; SDNN (male = 140 +/- 36ms vs. females = 122 +/- 33ms; p = 0.09), SDANN (male = 123 +/- 34ms vs. females = 111 +/- 34ms; P = 0.23), SDNNi (male = 64 +/- 19ms vs. females = 52 +/- 14ms; P = 0.03), and pNN50 (male = 14 +/- l0ms vs. females = 12 +/- 7ms; P = 0.43) were decreased in female volunteers when compared with males. Comparison of frequency domain indices; Total power (male = 4041 +/- 3150ms(2) vs. females = 2750 +/- 1439ms(2); P = 0.07), VLF (male = 2912 +/- 2675ms(2) vs. females = 1843 +/- 928ms(2); P = 0.06), LF (male = 788 +/- 397ms(2) vs. females = 556 +/- 346ms(2); P = 0.04) and HF (male = 318 +/- 251ms(2) vs. females = 312 +/- 277ms(2): P = 0.94) amongst males and females showed attenuated heart rate variability in females. Of all the observed values, SDNNi and LF were found significantly (p < 0.05) decreased in women. CONCLUSION In healthy population, heart rate variability is low in women than men. It reflects sympathetic dominance in women in our population.
Study on topology of magnetic gear considering shape of pole piece

In this paper, conventional Magnetic Gear (MG), which has Surface Mounted Permanent Magnet rotor Magnetic Gear (SPMMG), and Consequent pole Permanent Magnet rotor Magnetic Gear (CPMMG), which has high torque density, is analyzed. For analysis, various pole pieces shape considering flux density distribution and leakage flux in pole piece core are studied. Moreover proposed design variables are adopted to analyze torque characteristics which are average torque and torque ripple. In addition, two types of MG are analyzed considering torque density according to MG volume and magnet usage. Analysis on SPMMG and CPMMG is verified by 2D Finite Element Analysis (FEA).
Gastric Bypass May Promote Weight Loss in Overweight Partners

Introduction: Following bariatric surgery, patients are expected to implement diet and lifestyle changes that may be imitated by cohabitating family members. We hypothesize that cohabitating family members will lose weight and improve their eating behavior within 1 year after surgery. Methods: In this observational prospective study, family members of patients who had gastric bypass surgery (88 partners, 20 children ≥18 years old, and 25 children between 12 and 17 years old) were repeatedly assessed. Family members were asked to assess their weight and height before and 3, 6, and 12 months following bariatric surgery, and they filled out the Dutch Eating Behavior Questionnaire. Results: Between baseline and 1 year following surgery, 49 partners of patients who underwent gastric bypass surgery (66.2%) lost weight, 6 (8.1%) remained stable, and 19 (25.7%) gained weight. Body mass index of partners (P = .002), particularly of overweight partners (P < .001)—but not children—showed a small, significant decrease over time. No significant changes in eating behavior among partners or children were found. Conclusion: The study indicates that gastric bypass surgery may have a ripple effect, with body weight in partners of patients decreasing over time. However, there is considerable variation in the postoperative weight loss of partners.
Identification of novel genetic susceptibility loci in African American lupus patients in a candidate gene association study.

OBJECTIVE Candidate gene and genome-wide association studies have identified several disease susceptibility loci in lupus patients. These studies have largely been performed in lupus patients who are Asian or of European ancestry. This study was undertaken to examine whether some of these same susceptibility loci increase lupus risk in African American individuals. METHODS Single-nucleotide polymorphisms tagging 15 independent lupus susceptibility loci were genotyped in a set of 1,724 lupus patients and 2,024 healthy controls of African American descent. The loci examined included PTPN22, FCGR2A, TNFSF4, STAT4, CTLA4, PDCD1, PXK, BANK1, MSH5 (HLA region), CFB (HLA region), C8orf13-BLK region, MBL2, KIAA1542, ITGAM, and MECP2/IRAK1. RESULTS We found the first evidence of genetic association between lupus in African American patients and 5 susceptibility loci (C8orf13-BLK, BANK1, TNFSF4, KIAA1542, and CTLA4; P = 8.0 × 10⁻⁶, P = 1.9 × 10⁻⁵, P = 5.7 × 10⁻⁵, P = 0.00099, and P = 0.0045, respectively). Further, we confirmed the genetic association between lupus and 5 additional lupus susceptibility loci (ITGAM, MSH5, CFB, STAT4, and FCGR2A; P = 7.5 × 10⁻¹¹, P = 5.2 × 10⁻⁸, P = 8.7 × 10⁻⁷ , P = 0.0058, and P = 0.0070, respectively), and provided evidence, for the first time, of genome-wide significance for the association between lupus in African American patients and ITGAM and MSH5 (HLA region). CONCLUSION These findings provide evidence of novel genetic susceptibility loci for lupus in African Americans and demonstrate that the majority of lupus susceptibility loci examined confer lupus risk across multiple ethnicities.
An effective general framework for localized content optimization

Local search services have been gaining interests from Web users who seek the information near certain geographical locations. Particularly, those users usually want to find interesting information about what is happening nearby. In this poster, we introduce the localized content optimization problem to provide Web users with authoritative, attractive and fresh information that are really interesting to people around the certain location. To address this problem, we propose a general learning framework and develop a variety of features. Our evaluations based on the data set from a commercial localized Web service demonstrate that our framework is highly effective at providing contents that are more relevant to users' localized information need.
odd skipped related1 reveals a novel role for endoderm in regulating kidney versus vascular cell fate

The kidney and vasculature are intimately linked both functionally and during development, when nephric and blood/vascular progenitor cells occupy adjacent bands of mesoderm in zebrafish and frog embryos. Developmental mechanisms that underlie the differentiation of kidney versus blood/vascular lineages remain unknown. The odd skipped related1 (osr1) gene encodes a zinc-finger transcription factor that is expressed in the germ ring mesendoderm and subsequently in the endoderm and intermediate mesoderm, prior to the expression of definitive kidney or blood/vascular markers. Knockdown of osr1 in zebrafish embryos resulted in a complete, segment-specific loss of anterior kidney progenitors and a compensatory increase in the number of angioblast cells in the same trunk region. Histology revealed a subsequent absence of kidney tubules, an enlarged cardinal vein and expansion of the posterior venous plexus. Altered kidney versus vascular development correlated with expanded endoderm development in osr1 knockdowns. Combined osr1 loss of function and blockade of endoderm development by knockdown of sox32/casanova rescued anterior kidney development. The results indicate that osr1 activity is required to limit endoderm differentiation from mesendoderm; in the absence of osr1, excess endoderm alters mesoderm differentiation, shifting the balance from kidney towards vascular development.
Preparing Semantic Agents for an Unsuspecting and Unreliable World

Abstract : Semantic web-enabled agents offer tremendous promise for enabling automated coordination and negotiation amongst diverse participants. Ideally, a user should be able to quickly instruct his personal agent to achieve some goal, e.g., to schedule a meeting so that at least one representative of each division of the company would attend. This agent would then negotiate with the agents of all the invited participants, receiving prompt and definitive replies, and quickly reach consensus on an acceptable time. The original user would be involved again only when the goal was achieved. In reality, many problems are likely to arise: 1. Goal Specification: The user may know precisely what he wishes to have done, but instructing a general-purpose software agent to achieve this goal can be very complex. 2. Agent Proliferation: In a typical organization today, very few participants will know what a software agent is, much less have one that could act on their behalf. 3. Participant Reliability: Even if the user's agent is able to directly interact with the participants, many of them are likely to not respond, due to confusion about how to do so or general busyness. Moreover, those that do properly respond may later need to change their response, a situation that the user's agent may not be prepared to handle. 4. Evolving Goals: Finally, even the originating user may be uncertain about his precise goals. For instance, he may decide to invite new participants later, or to modify the goals after seeing the initial responses. Such changes pose technical challenges for the agent and may render its earlier actions irrelevant or even counter-productive. Collectively, these issues pose serious problems to the wide-scale deployment of useful, flexible semantic agents. In previous work, we examined the first issue by considering how ordinary people could specify flexible, explainable semantic agents (McDowell, Etzioni, & Halevy 2004).
Efficacy of Beam Thresholding, Unification Filtering and Hybrid Parsing in Probabilistic HPSG Parsing

We investigated the performance efficacy of beam search parsing and deep parsing techniques in probabilistic HPSG parsing using the Penn treebank. We first tested the beam thresholding and iterative parsing developed for PCFG parsing with an HPSG. Next, we tested three techniques originally developed for deep parsing: quick check, large constituent inhibition, and hybrid parsing with a CFG chunk parser. The contributions of the large constituent inhibition and global thresholding were not significant, while the quick check and chunk parser greatly contributed to total parsing performance. The precision, recall and average parsing time for the Penn treebank (Section 23) were 87.85%, 86.85%, and 360 ms, respectively.
Between a ROC and a hard place: decision making and making decisions about using the SCQ.

BACKGROUND The Social Communication Questionnaire (SCQ), formerly the Autism Screening Questionnaire (ASQ), is based on a well-validated parent interview, the Autism Diagnostic Interview (ADI). It has shown promise as a screening measure for autism spectrum disorders (ASDs) in a research-referred older sample, though recent studies with younger children reported lower sensitivities when using the suggested cutoff of > or = 15 to differentiate ASDs from children with nonspectrum disorders (NS). METHODS Diagnostic discrimination of the SCQ was evaluated alone and in combination with the ADOS (Autism Diagnostic Observation Schedule) in a clinical and research-referred sample of 590 children and adolescents (2 to 16 years), with best estimate consensus diagnoses of autism, pervasive developmental disorder, not otherwise specified (PDD-NOS) and non-ASD disorders. The SCQ was completed before the evaluation in most cases. Performance of the SCQ was also compared with the Autism Diagnostic Interview - Revised (ADI-R). RESULTS Absolute scores and sensitivity in the younger children and specificity for all groups were lower than reported in the original study. Using receiver operating curves (ROC) to examine the area under the curve (AUC), the SCQ was more similar to the ADI-R total score in differentiating ASD from NS disorders in the older (8-10, >11) than younger age groups (<5, 5-7). Lowering the cutoff score in the 2 younger groups improved sensitivity, with specificity remaining relatively low in all groups. Using the SCQ in combination with the ADOS resulted in improved specificity. Diagnostic discrimination was best using the ADI-R and ADOS in combination. CONCLUSIONS Those interested in using the SCQ should consider adjusting cutoff scores according to age and purpose, and using it in combination with another measure. Sensitivity or specificity may be prioritized for research or screening depending on goals.
Analysis on Trendy Characteristics and differences of Environmental Kuznets Curve of Main Pollutants in Chinese big urban area

On the Base of relevant data relationship between economic growth and environment quality are analyzed to show Trendy Characteristics of Environmental Kuznets Curve of Main Pollutants in Beijing and Tianjin Region during 1985∼2008. It is concluded that new type curves which differ form traditional EKC curve are possible. The overall relationship between the environment and the economy in Beijing and Tianjin region has entered a “win-win” stage, while the pressure of pollution control is greater in Beijing. The turning points of major pollutant EKC in Beijing and Tianjin region are slightly lower than that in the developed countries. In addition, the trendy characteristics of the same kind of pollutants are quite similar in Beijing and Tianjin regions.

A 2/5mW CMOS Delta Sigma modulator employed in an improved GSM/UMTS receiver structure

In this paper, the design of a reconfigurable low-power low-pass Switched Capacitor Delta-Sigma (SC ΔΣ) modulator for GSM/UMTS standards used in an optimum low-IF(LIF)/Zero-IF(ZIF) receiver architecture is described. A new approach for obtaining the optimum modulator coefficients is developed which results in relaxed specifications of the circuit components, aggressive noise transfer function (NTF) and a signal transfer function (STF) with the blocker-rejection property. The modulator employs a second/third-order single-stage dual-quantizer structure. It achieves 85.6dB/57dB SNDR and -0.2dBFS/-0.05dBFS overload factor at 0.2/2MHz bandwidth for GSM/UMTS standards and consumes only 2mW/5mW from a single 1.8V supply in a 0. 18µm 1P6M CMOS process. The maximum spread of the modulator capacitors is 105.
Statistical Mechanics of Temporal Association in Neural Networks

We study the representation of static patterns and temporal associations in neural networks with a broad distribution of signal delays. For a certain class of such systems, a simple intuitive understanding of the spatio-temporal computation becomes possible with the help of a novel Lyapunov functional. It allows a quantitative study of the asymptotic network behavior through a statistical mechanical analysis. We present analytic calculations of both retrieval quality and storage capacity and compare them with simulation results.
Home appliance translator for remote control of conventional home appliance

We developed the HAT (home appliance translator) and HAT-Sub to enable conventional appliances without telecommunication capabilities to connect to home networks. The demand is rising for home appliances to connect to networks so that they can be remotely controlled, however, purchasing information appliances places financial strain on users. If conventional appliances could connect to home networks, this problem would be solved. X-10 devices can do that, but they can only turn appliances on and off. HATs and HAT-Subs allow more advanced control and determine the state of a conventional appliance in more detailed by using an IR signal and supplied electricity. The user can program a VCR and adjust the temperature of a heater and remotely determine whether those tasks were correctly done by using HATs and HAT-Subs. These devices use power lines for automatic communication. Users can construct home networks more easily and cheaply, without information appliances, new communication infrastructures, or complex settings.
The application of Principal Component Analysis to materials science data

The relationship between apparently disparate sets of data is a critical component of interpreting materials' behavior, especially in terms of assessing the impact of the microscopic characteristics of materials on their macroscopic or engineering behavior. In this paper we demonstrate the value of principal component analysis of property data associated with high temperature superconductivity to examine the statistical impact of the materials' intrinsic characteristics on high temperature superconducting behavior
PreMOn: a Lemon Extension for Exposing Predicate Models as Linked Data

We introduce PreMOn (predicate model for ontologies), a linguistic resource for exposing predicate models (PropBank, NomBank, VerbNet, and FrameNet) and mappings between them (e.g, SemLink) as Linked Open Data. It consists of two components: (i) the PreMOn Ontology, an extension of the lemon model by the W3C Ontology-Lexica Community Group, that enables to homogeneously represent data from the various predicate models; and, (ii) the PreMOn Dataset, a collection of RDF datasets integrating various versions of the aforementioned predicate models and mapping resources. PreMOn is freely available and accessible online in different ways, including through a dedicated SPARQL endpoint.
MontiCore: a framework for the development of textual domain specific languages

In this paper we demonstrate a framework for the efficient development of textual domain specific languages and supporting tools. We use a redundance-free and compact definition of a readable concrete syntax and a comprehensible abstract syntax as both representations significantly overlap in their structure. To further improve the usability of the abstract syntax, this definition format integrates additional concepts like associations and inheritance into the well-understood grammar-based approach. Modularity concepts like language inheritance and embedding are used to simplify the development of languages based on already existing ones. In addition, the generation of editors and a template approach for code generation is explained.
Harmonic Change Detection for musical chords segmentation

In this paper, different strategies for the calculation of the Harte's Harmonic Change Detection Function (HCDF) are discussed. HCDFs can be used for detecting chord boundaries for Automatic Chord Estimation (ACE) tasks, where the chord transitions are identified as peaks in the HCDF. We show that different audio features and different novelty metric have significant impact on the overall accuracy results of a chord segmentation algorithm. Furthermore, we show that certain combination of audio features and novelty measures provide a significant improvement with respect to the current chord segmentation algorithms.
Scientiﬁc Literature Retrieval based on Terminological Paraphrases using Predicate Argument Tuple

The conceptual condensability of technical terms permits us to use them as effective queries to search scientific databases. However, authors often employ alternative expressions to represent the meanings of specific terms, in other words, Terminological Paraphrases (TPs) in the literature for certain reasons. In this paper, we propose an effective way to retrieve “de facto relevance documents” which only contain those TPs and cannot be searched by conventional models in an environment with only controlled vocabularies by adapting Predicate Argument Tuple (PAT). The experiment confirms that PAT-based document retrieval is an effective and promising method to search those kinds of documents and to improve terminology-based scientific information access models.
Mechanical Pressure Versus Intrinsic Effects of Hypertension on Large Arteries in Humans

Brachial artery diameter and compliance were measured in 23 normotensive control subjects and 49 hypertensive patients. The results were compared in isobaric conditions by a modeling analysis extrapolating from the measured data a short segment of the pressure-diameter and pressure–compliance curves in the artery. A logarithmic diameter-pressure function was used as well as measurements of brachial artery blood pressure and lumen diameter (by pulsed Doppler), and of brachial-to-radial pulse wave velocity (by mechanography). The measured values of diameter and compliance in the hypertensive patients were 109% and 63%, respectively, of the control group values. By extrapolating the data via the model at the same pressure level in all subjects (the average level of mean blood pressure of the two groups), the isobaric values of diameter and compliance in the hypertensive patients were 107% and 81%, respectively, of the control group values. Overall, measured isobaric diameters and measured compliance correlated with systolic, diastolic, and mean blood pressure values (p<0.001), whereas isobaric compliance correlated only with systolic (p<0.05) and pulse (p<0.01) pressure values. Thus, the increased diameter and reduced compliance of the brachial artery observed in hypertensive humans cannot be attributed solely to the stretching effect of elevated blood pressure, but also to intrinsic alteration of the arterial walls. These could represent either adaptative structural or functional changes secondary to the chronic increase in arterial pressure, or primary abnormalities of the vessel wall.
Split ring EM field response towards modified triangular and tapered edge tip within a WR159 waveguide

This paper investigates the effect of bringing together a triangular tip edge and tapered tip edge at the longest arm split gap of a circular split ring and its effect towards the electric and magnetic field. Conducted using tetrahedral mesh type frequency based numerical simulation by modeling the behavior of the circular rings located centered wise in a standard WR159 waveguide in comparison to the conventional circular split ring resonators. The less electrical field sensitivity of the conventional circular split ring had been strengthened from 5.19e+04 V/m to 5.36e+04 V/m and magnetic field sensitivity from 149 A/m to 218 A/m with a 3.27 % increase while retaining the operating frequency well at 5.9 GHz. The properties of this resonance response could be used to design numerous novel C-Band metamaterials applications.
