The design of ultra wideband six-port network by using ground-slotted technique

A new design of compact ultra wideband (UWB) six-port network by using ground-slotted technique is presented in this paper. The proposed six-port network is accomplished by constructing four in-phase two-section power dividers and two 90o power dividers by using CST Microwave Studio 2010. The presented result shows that the proposed UWB six-port network offers good amplitude and phase characteristic performances for frequency range of 3.1 to 10.6 GHz.
A learned emotion space for emotion recognition and emotive speech synthesis

Emotion is a complex phenomenon that contributes heavily to human communication. Typically, human-computer interaction and text-to-speech systems do not account for emotion information, possibly due to lack of accurate emotion recognition and emotive speech synthesis methods. It seems likely that emotion recognition and synthesis has the ability to greatly improve how humans interface with machines. Existing methods in speech recognition make use of a wide range of features and models. However, these methods make use of either categorical, or appraisalbased emotion descriptions. We believe these have flaws that limit their ability to describe emotion. We present several neural network models for emotion recognition. In addition, we propose an abstract emotion space that avoids the flaws of existing emotion descriptions. We use stimulation to improve the interpretability of our emotion space, along with multi-task learning to improve its robustness. Finally, we investigate auxiliary features for style adaptation in statistical parametric speech synthesis, evaluating both our emotion space and other descriptions of emotion. The results indicate that our recognition models are state-of-the-art. However, evaluation using speech synthesis shows that our emotion space is no more informative than existing emotion descriptions. Additionally, we investigate a convolutional recognition model using the spectrogram, which outperforms other spectrogram based methods.
A novel battery charger operated from random sound sources or air pressure

Design and implementation of a novel cell phone charger using renewable energy is reported in this work. Conventional cell phone charger takes main line ac source as input, then rectify it and step it down to charge the battery. The cumulative power taken per day from the main line by all the mobile phone users over the world or in a single country is not a small amount. So, if there is alternative way of charging mobile batteries, a significant amount of power can be saved. Here, random sound energy or air pressure is proposed as a new source of renewable energy which can be easily used to charge a mobile phone battery through suitable energy conversion circuit. Piezoelectric material is used here as the transducer to convert sound energy or air pressure into electric energy. The produced electric energy is then processed through simple circuit to make suitable output which can directly charge any commonly used cell phone battery. The proposed set up is simple, portable and especially useful in rural areas where there is no electric power at all. It is also helpful during natural disaster when electric power may not be available in a particular area. The performance of the circuit for different frequencies of sound was tested. Some ways to improve the overall performance of this circuit were also prescribed.
Prevalence of Sarcopenia among Nursing Home Older Residents in Cairo, Egypt

Sarcopenia is highly prevalent in community dwelling older adults in many countries; however, the prevalence of sarcopenia in nursing home older residents is not well characterized. The aim of this study is to assess the prevalence of sarcopenia in nursing home older residents in Cairo. Cross sectional study was performed among 357 nursing home residents in Cairo. The European Working Group on Sarcopenia in Older People (EWGSOP) recommendation was used for diagnosing sarcopenia. The study showed that the prevalence of sarcopenia in nursing home older residents in Cairo was 17.7%, 22.2% in elderly men and 14.4% in elderly women. Age, underweight and lack of physical activity were found to be associated with sarcopenia among studied participants. The study concluded that sarcopenia is an emerging health problem in nursing home older residents in Cairo.
Body-related experiences of two young rural Aboriginal women

There has been a gradual increase in health research that explores the body-related experiences of young Aboriginal women living in urban and reserve settings. However, the voices of rural Canadian Aboriginal women not living on reserves, appear to be absent from this literature. The purpose of this study, therefore, is to better understand the body-related experiences of young Aboriginal women living in rural Canadian communities. Case study was utilized as the strategy of inquiry in which each of two young women (both 15 years of age) represented a case. One-on-one interviews were used to explore the young women’s experiences. Four themes emerged: (1) fitting in, (2) rural uniqueness, (3) role models, and (4) body talk. The primary contribution of this study is that it sheds light on the unique body-related experiences of two young women, each living in a rural community where she is the only teenaged Aboriginal woman. Despite some similarities, the young women related very different stories of their experiences in their respective communities. This research also highlights some of the ethical challenges of ensuring that the stories of the young women are adequately represented, while their confidentiality is respected.
A Structural Approach to Estimate Market-Assessed Sovereign Credit Risk

This paper explores the economic determinants of market-assessed sovereign risk of members of the European monetary union. The empirical work is innovative in its Merton structural specification of appropriate inputs. It provides a theoretical background for the empirical investigation of sovereign risks. We make use of publicly available government financial statistics as well as national stock market volatility estimated by EGARCH, implied from traded options and by fitting a generalized Pareto distribution. We show a high degree of association between our modelled spreads and credit default swap spreads using volatility estimates based on option implied and generalized Pareto distribution. Model performance holds in out-of-sample prediction and the non-linear model derived from structural theory is shown to outperform a benchmark linear regression model.These results provide policy makers and regulators with a set of insights into the factors which influence credit market activity enabling them to take an informed approach to policy and regulatory settings which will be subject to market appraisal.
A robust tracking-by-detection approach based on partial update strategy

The goal of visual tracking is to estimate the location of the visual target in a sequence of images. If the video has long-term sequence of images, the tracking task without prior information is severely difficult due to the occlusion or the disappearance. Recently, tracking-by-detection methods have been proposed to solve the long-term tracking problem. However, most of them also suffer from drifting, since they did not sufficiently consider the labeling problem when updating the detector. In this paper, a robust tracking approach via a novel partial update strategy is proposed. The proposed strategy is based on the thinking that unoccluded area of the target still includes useful information, while the use of the whole area will degrade the performance of the detector. As a result, the proposed partial update strategy effectively improves the performance of the tracking-by-detection method in the presence of partial occlusions and abrupt changes of illumination.
Coupling-Independent Wireless Power Transfer

It is well known that mid-range wireless power transfer can be realized by a link consisting of mutually coupled series resonant circuits operating at the common resonant frequency. However, in such conditions, the link load which maximizes the output power or the transfer efficiency is coupling dependent. This letter provides an analytical solution to this problem by exploiting the frequency bifurcation phenomenon, which occurs after a certain threshold value of the coupling. When the system is operated at one of the secondary resonances, it behaves as an ideal transformer; thus, it is able to deliver to a prescribed load constant output power with constant efficiency. This is true for variable coil distances or coil misalignment, that is, for variable coupling coefficient.
Targeting anti-HIV drugs to the CNS

The development of antiretroviral drugs over the past couple of decades has been commendable owing to the identification of several new targets within the overall HIV replication cycle. However, complete control over HIV/AIDS is yet to be achieved. This is because the current anti-HIV drugs, although effective in reducing plasma viral levels, cannot eradicate the virus completely from the body. This occurs because most anti-HIV drugs do not accumulate in certain cellular and anatomical reservoirs including the CNS. Insufficient delivery of anti-HIV drugs to the CNS is attributed to their low permeability across the BBB. Hence, low and sustained viral replication within the CNS continues even during prolonged antiretroviral drug therapy. Therefore, developing novel approaches that are targeted at enhancing the CNS delivery of anti-HIV drugs are required. In this review, we discuss the potential of nanocarriers and the role of cell-penetrating peptides in enhancing drug delivery to the CNS. Such drug delivery approaches could also lead to higher drug delivery to other cellular and anatomical reservoirs where the virus harbors than with conventional treatment, thus providing an effective therapy to eliminate the virus completely from the body.
Modified SURF Applied in Remote Sensing Image Stitching

With the development of satellite technology, the application of remote sensing images becomes more and more significant. The coverage of a single remote sensing image is limited, so remote sensing images should be stitched into a larger image by overlapping region. SURF is a commonly algorithm for image mosaic, but the calculation of this algorithm is too heavy. Thus, we propose the method of modified SURF applied in remote sensing image stitching. Firstly, we extract basic feature points by Hessian matrix. Secondly, we improve the accuracy of feature point matches by use of FLANN algorithm and RANSAC. Finally, we take advantage of the algorithm of overlapping region weighted average to blend remote sensing images. Through the experiment, we can prove that the image stitching system can implement remote sensing image mosaic, which enables the smooth transition for image blending and has superiority and efficiency about image stitching.
Improving your software using static analysis to find bugs

FindBugs looks for bugs in Java programs. It is based on the concept of bug patterns. A bug pattern is a code idiom that is often an error. Bug patterns arise for a variety of reasons, such as difficult language features, misunderstood API semantics, misunderstood invariants when code is modified during maintenance, garden variety mistakes: typos, use of the wrong boolean operator and simple mistakes such as typos.FindBugs uses static analysis to inspect Java bytecode for occurrences of bug patterns. We have found that FindBugs finds real errors in most Java software. Because its analysis is sometimes imprecise, FindBugs can report false warnings, which are warnings that do not indicate true errors. In practice, the rate of false warnings reported by FindBugs is generally lower than 50%, often much lower.
Ten-year study comparing enzyme-linked immunosorbent assay with the immunofluorescent antibody test for detection of feline leukemia virus infection in cats.

Immunodetection tests for feline retroviruses are powerful tools used in modern veterinary practice. Veterinarians must fully understand the characteristics--strengths and weaknesses--of the FeLV tests so that the information gained from them can be used properly. Any FeLV ELISA or immunofluorescent antibody (IFA) test is a method for detection of FeLV infection (the virus) and is not a diagnostic test for leukemia or other feline disease. From previous studies, it was determined that the most accurate test for detection of persistent FeLV infection is the IFA test, which detects FeLV antigens in cytoplasm of leukocytes in the blood of infected cats. In the study reported here, 1,142,600 FeLV IFA tests were performed between June 1972 and December 1990. During this period 19.8% of the IFA test results were positive and 78% were negative. Evaluation was not possible for the remaining 2.2% of the tests because of lack of enough leukocytes in the smears to evaluate, or nonspecific staining reactions. In 1979, 7 years after introduction of the IFA test, in-hospital FeLV ELISA were introduced, which enabled veterinarians to test for FeLV in their hospitals. Ever since that time, continual discrepancies have been reported between results of FeLV ELISA and IFA tests, particularly between positive ELISA results and their IFA test confirmation. A 10-year comparison was made between practitioner-performed in-hospital FeLV ELISA (n = 20, 240 tests) results and FeLV IFA test performed by a commercial laboratory. All samples tested by ELISA were submitted (for confirmation of results) by veterinarians from the United States, Canada, Europe, Japan, and Australia. (ABSTRACT TRUNCATED AT 250 WORDS)
Discrimination between individual humans by domestic fowl ( Gallus gallus domesticus )

1. We demonstrate that Barred-Rock and Isa-Brown hens can discriminate between the presence of 2 different humans and use this information as a cue for whether or not to make an operant response. 2. This demonstration in domestic fowl, the first of its kind in any avian subject, is consistent with a growing body of evidence that many species, including agricultural animals, are surprisingly adept at differentiating between humans. 3. Such a discriminative ability carries considerable implications for issues related to husbandry, production and welfare.

Using Wikipedia for Extracting Hierarchy and Building Geo-Ontology

Purpose – This paper aims to serves two main purposes: First, it seeks to provide an overview of the location hierarchy from the highest divisions (continents) to the lowest divisions (wards, villages) in reality and in the Wikipedia pages. Secondly, it aims to introduce an approach to building a geographical ontology from Wikipedia.Design/methodology/approach – The paper first reviews existing applications which extract information from Wikipedia and use it as a data resource to develop natural language processing tools. The paper also reviews the structure of Wikipedia pages which show the location's information. Based on the analysis, the paper then proposes an approach to extract location hierarchy as well as geographical characteristics for the geo‐ontology. The approach also rebuilds the relations between locations in the ontology.Findings – Existing location name systems are mainly based on probabilistic locations, which are mined from the data and they lack the administrative relations between loc.
Crystal structure of atomic hydrogen.

We have performed quantum Monte Carlo calculations on atomic metallic hydrogen at zero temperature and constant volume (r s =1.31) for protons rigidly fixed to lattice sites and for protons having zero point motion. By studying a variety of crystal structures including bcc, simple cubic, simple hexagonal, diamond, and β-Sn, we show that low-coordination structures, especially diamond, are energetically favored for a range of pressures around 3.0 Mbars. Our results show that it is essential to treat the electrons beyond the local density approximation and protons beyond the harmonic approximation to predict the correct ground state structure
Microbial diversity of different modified atmosphere packed pot‐stewed duck wings products during 8°C storage

The objective of this study was to investigate the effect of spices and packaging films on the bacterial dynamics of pot‐stewed duck wings (PSDW) during storage at 8°C. The results showed that spices added at a 1 : 1 ratio (weight ratio of pungent spices and fragrant spices) could delay the lag period of bacterial growth and extend the shelf‐life of PSDW. Denaturing Gel Gradient Electrophoresis (DGGE) analysis indicated that the predominant bacteria in PSDW at the end of storage were Weisella hellenica, Weisella diestrammenae, Staphylococcus equorum and Streptococcus parauberis, and spices added at a 1 : 1 ratio showed better inhibition for bacteria at the end of storage, except for W. hellenica. Thus, general‐purpose and high barrier films in modified atmosphere packaging, had a good barrier effect for the isolation of air, and showed no effect on the bacteria. This study will help PSDW processing companies to understand the biodiversity of PSDW, and provide a scientific basis for the extension of shelf‐life.
Direct polarization-heterodyne measurement of Kerr-induced birefringence in optical fibers

We have directly measured the amount of birefringence induced by nonlinear Kerr effect in standard optical fibers, by means of a double-polarization-heterodyne method, suitable for characterizing short samples of fibers. Birefringence is measured with a resolution of /spl Delta/n/spl ap/10/sup -12/ and the optical Kerr coefficient is extracted. The agreement of experimental results and theoretical predictions confirms the accuracy of the technique.
Quantifying Bird-HaBitat using a relevé MetHod

The relevé method, a standardized, floristically based vegetation sampling technique developed in Europe, has become a vegetation measurement method used worldwide. Although the relevé method was developed by plant ecologists to classify vegetation, ornithologists have begun to use the method for bird-habitat studies, sometimes including modifications to better sample structural features of a habitat thought to influence bird occupancy. To evaluate the potential for these data to provide information about bird habitat, we compared the use of data acquired using an original relevé method to a modified relevé method to build explanatory bird occupancy models. Furthermore, time and effort required to collect relevé method data were compared against widely used vegetation data collection methods. In 2004-2005, point counts for bird occurrences, relevé vegetation measurements following original methods used by the California Native Plant Society, and a modified relevé method implemented by the California Department of Fish and Game, and time and effort data for both methods were collected in the Sierra Nevada foothill blue oak (Quercus douglasii) woodlands of Yuba and Nevada Counties, California. Occupancy models were built using both the original and modified relevé data for three focal bird species important in California’s oak woodlands. Site occupancy and probability of detection showed strong associations with covariates collected using the original relevé method for spotted towhee (Pipilo maculates), whereas models for white-breasted nuthatch (Sitta carolinensis) were best supported using variables collected from both the original and the modified relevé methods. Environmental variables, which were not exclusive to either the original or modified relevé method, best predicted lark sparrow (Chondestes grammacus) occupancy and were competitive when compared to models built using relevé data for spotted towhee and white-breasted nuthatch. The modified relevé method, on average, was a more efficient method compared to the original relevé method and other common bird habitat quantification methods. Future research should focus on directly comparing data acquired using relevé methods to those of other bird-habitat quantification methods to test the accuracy of data in building explanatory bird-habitat relationship models.
Web Communities in Big Data Era. Editorial

Web-based community is a self-defined web-based network of interactive communication organized around a shared interest or purpose. It provides the means of interactions among people in which they create, share, and exchange information and ideas in virtual space and networks. Working with big data often requires querying and reasoning that data to isolate information of interest and manipulate it in various ways. This editorial paper explores recent big data research topics -- stream querying and reasoning -- over data from web based communities. It combines aspects from some well-studied research domains, such as, social network analysis, graph databases, and data streams. We provide a brief synopsis of some research issues in supporting reasoning and querying tasks. This editorial also presents the WI&C-16 workshop's goal and programme.
ICT and Innovation in the Provision of Public Services: The Case of Slovakia

This paper discusses factors which determine the adoption of information and communication technology (ICT) in public services. The provision of online public services is becoming increasingly utilized as a means to streamline and facilitate contact between citizens and public-sector bodies. The implementation of decentralization process also makes the accessibility of public services to citizens simpler. In this paper, the online services and factors which determine the level of such services are analyzed using the data set of 1216 services provided by municipalities in Slovakia. Special attention is paid to the examination of financial indicators which describe financial independence of local governments with respect to the assumption that local governments with higher level of expenditure covered by the revenue coming from proper taxes display more effective behavior in the field of public services. Thereafter, based on the results of econometric model and statistical methods key factors affecting the provision of online services are determined. The results of the model show that a higher level of ICT adoption in public services is achieved by larger municipalities which are district seats and which are financially autonomous. This is an important lesson for the policy as the process of fiscal decentralization appears to be a very important means of narrowing the gap between the developed and transition economies.
