Low complexity LMS based adaptive iterative receiver for CDMA systems

An adaptive iterative frequency domain receiver for a Layered Space-Time Coded CDMA (LSTC-CDMA) system has been proposed in this paper. The proposed receiver, based on a joint adaptive iterative detection and decoding algorithm, adaptively cancels Co-Channel Interference (CCI) and mitigates Multiple Access Interference (MAI), and also has a significant reduction in computation complexity with the same performance compared to a time domain receiver. The Least Means Square (LMS) algorithm is used for both feed-forward filter and feedback filter in the adaptive detection. A Partially Filtered Gradient LMS (PFGLMS) algorithm is also proposed to improve the convergence speed of the adaptive detector. The performance results show that the proposed adaptive receiver can approach the interference-free single user performance for a certain range of the signal to noise ratio (SNR).
The Experience of Risk-Adjusted Capitation Payment for Family Physicians in Iran: A Qualitative Study

Background When a country’s health system is faced with fundamental flaws that require the redesign of financing and service delivery, primary healthcare payment systems are often reformed. Objectives This study was conducted with the purpose of exploring the experiences of risk-adjusted capitation payment of urban family physicians in Iran when it comes to providing primary health care (PHC). Materials and Methods This is a qualitative study using the framework method. Data were collected via digitally audio-recorded semi-structured interviews with 24 family physicians and 5 executive directors in two provinces of Iran running the urban family physician pilot program. The participants were selected using purposive and snowball sampling. The codes were extracted using inductive and deductive methods. Results Regarding the effects of risk-adjusted capitation on the primary healthcare setting, five themes with 11 subthemes emerged, including service delivery, institutional structure, financing, people’s behavior, and the challenges ahead. Our findings indicated that the health system is enjoying some major changes in the primary healthcare setting through the implementation of risk-adjusted capitation payment. Conclusions With regard to the current challenges in Iran’s health system, using risk-adjusted capitation as a primary healthcare payment system can lead to useful changes in the health system’s features. However, future research should focus on the development of the risk-adjusted capitation model.
Frequency stability improvement of low inertia systems using synchronous condensers

In order to meet the energy demand and at the same time to achieve sustainable development objectives on a global scale, the Danish government has set a long-term strategy of fossil fuel free country by the year 2050. However, the decline of conventional power generation units and a rising amount of converter interfaced components (wind turbine, HVDC, and Photovoltaic) may have negative effects on the stability of the power system. These components do not have enough inertia response to control frequency excursion, so the power grid can depend on few synchronous machines for frequency regulation and reduce the system inertia. Consequently, the frequency stability of the system will be easily jeopardized. To address these issues, the paper studies frequency characteristics of future Western Danish renewable-based system that uses a majority of wind turbine generators. Different scenarios of wind turbine penetration, governor responsibility of synchronous generators, and disturbance are simulated to examine the impact of high-level renewable energy integration on the system frequency characteristics. The effect of synchronous condensers for the frequency stability enhancement is investigated. It can be concluded from the comparative simulation results that synchronous condenser demonstrates a satisfactory performance for improving the system frequency stability.
Anxiété et troubles cognitifs Anxiety and cognitive deficit

sentiment de déjà-vu ou de jamais-vu), des déficits mnésiques et attentionnels, ainsi que des perturbations émotionnelles et affectives. Les perturbations attentionnelles sont à l’origine d’une partie des troubles de la mémoire observés chez les sujets anxieux. Il y aurait, selon M.W. Eysenck (2), plusieurs effets de l’anxiété sur l’attention. Les sujets anxieux auraient tendance à rechercher les stimuli menaçants se rapportant à leurs symptômes. Ils présenteraient des troubles de l’attention se manifestant par une grande distractibilité. De plus, leur attention serait sélective, c’est-à-dire qu’ils focaliseraient leur attention sur des informations bien spécifiques. Enfin, les ressources attentionnelles concernant leur mémoire de travail seraient limitées. Dans le test de Stroop, les patients présentant une anxiété généralisée sont plus lents à dénommer la couleur lorsque les mots présentés ont une connotation péjorative (par exemple, “infarctus”). Il en est de même chez des patients souffrant de phobie simple lorsque le mot désigne directement le stimulus phobogène lui-même (par exemple, “obscurité”). Dans l’attention visuospatiale, certaines études ont mis en évidence un biais attentionnel en faveur des stimuli menaçants. La nature sémantique des mots présentés interviendrait également. Le patient anxieux effectuerait un traitement sémantique inconscient des mots. Plus le mot est congruent à ses préoccupations et plus l’interférence serait grande. L’anxiété mobiliserait une partie des ressources attentionnelles des patients, ce qui les placerait dans une situation de double tâche (3). En effet, les patients souffrant d’anxiété doivent traiter à la fois l’information pertinente et celle liée à l’anxiété, ce qui entraîne un effort attentionnel plus important. Pour le trouble anxieux généralisé (TAG), aucun biais en mémoire explicite n’a été trouvé. Il en existe cependant un en mémoire implicite pour les mots à connotation menaçante (4). L’existence de déficits mnésiques dans les troubles obsessionnels compulsifs (TOC) a été mise en évidence à plusieurs reprises. En effet, plusieurs études ont montré que les patients souffrant de TOC présentaient des déficits de la mémoire visuospatiale, mais non de la mémoire verbale. Dans l’état de stress post-traumatique (ESPT), certaines caractéristiques du souvenir traumatique et des réactions aux traumatismes montrent que les émotions du sujet sont essentiellement représentées par les flash-back plutôt que par des formes de souvenirs ordinaires. Ces derniers incorporent des pensées concernant la mort et le fait de mourir, qui sont des prédicteurs importants du développement de l’ESPT (5), ainsi que l’existence de séquences interconnectées et d’images plutôt que de scènes séparées (6).
A Scalable Runtime for the ECOSCALE Heterogeneous Exascale Hardware Platform

Exascale computation is the next target of high performance computing. In the push to create exascale computing platforms, simply increasing the number of hardware devices is not an acceptable option given the limitations of power consumption, heat dissipation, and programming models which are designed for current hardware platforms. Instead, new hardware technologies, coupled with improved programming abstractions and more autonomous runtime systems, are required to achieve this goal. This position paper presents the design of a new runtime for a new heterogeneous hardware platform being developed to explore energy efficient, high performance computing. By extending and enhancing the OpenCL framework, this work will both simplify the programming of current and future HPC applications, as well as automating the scheduling of data and computation across this new hardware platform. Also, this work explores the use of FPGAs to achieve both the power and performance goals of exascale, as well as utilising the runtime to automatically effect dynamic configuration and reconfiguration of hardware platforms.
Pengaruh Person-Organization Fit (P-O Fit), Motivasi Kerja, dan Kepuasan Kerja terhadap Komitmen Pegawai (Pada Pegawai UB Hotel, Malang)

The importance of employee commitment reflects the good relationship between employees and organizations. Employee commitment can be influenced by some factors, such as person-organization fit (P-O Fit), job motivation, and job satisfaction. This study has objective to analysis the person-organization fit, job motivation, and job satisfaction influences toward employee commitment. Researcher uses 60 em- ployees as sample in the UB Hotel, exclude the Director Data is analyzed by using Partial Least Square (PLS). The result shows that person-organization fit has a positive and significant influence on job motiva- tion, job satisfaction, and employee commitment. Also, job motivation and job satisfaction have a positive and significant influence on the employee commitment. In the other hand, there is an indirect relationship between person-organization fit toward employee commitment through job motivation or job satisfaction
The Truly Disadvantaged

Renowned American sociologist William Julius Wilson takes a look at the social transformation of inner city ghettos, offering a sharp evaluation of the convergence of race and poverty. Rejecting both conservative and liberal interpretations of life in the inner city, Wilson offers essential information and a number of solutions to policymakers. The Truly Disadvantaged is a wide-ranging examination, looking at the relationship between race, employment, and education from the 1950s onwards, with surprising and provocative findings. This second edition also includes a new afterword from Wilson himself that brings the book up to date and offers fresh insight into its findings. “ The Truly Disadvantaged should spur critical thinking in many quarters about the causes and possible remedies for inner city poverty. As policymakers grapple with the problems of an enlarged underclass they—as well as community leaders and all concerned Americans of all races—would be advised to examine Mr. Wilson's incisive analysis. ”—Robert Greenstein, New York Times Book Review
Urinary Level of CA 19-9 as a Tumor Marker in Urothelial Carcinoma of the Bladder

Purpose: To diagnose the urothelial carcinoma of the bladder by measuring CA19-9 level in the urine. Materials and Methods: This study was conducted on 47 patients with histopathologically confirmed urothelial cancer and 50 control subjects. The urinary level of CA19-9 was measured in both groups by enzyme-linked immunosorbent assay after concentration of urine with Bio-Gel dry beads. Urine cytology was also done in both controls and patients. Results: The mean urinary level of CA19-9 was 194.59 ± 110.56 u/mL in patients and 11.67 ± 8.42 u/mL in controls (P = .0001). The mean urinary level of CA19-9 in patients with low-grade and high-grade bladder cancer was 206.56 ± 114.56 u/mL and 174.80 ± 94.06 u/mL, respectively (P = .56). Urine cytology by Papanicolaou stain was mostly negative. Conclusion: It can be concluded that CA19-9 may be a useful non-invasive test to diagnose the urothelial carcinoma of the bladder.
Sporosarcina aquimarina sp. nov., a bacterium isolated from seawater in Korea, and transfer of Bacillus globisporus (Larkin and Stokes 1967), Bacillus psychrophilus (Nakamura 1984) and Bacillus pasteurii (Chester 1898) to the genus Sporosarcina as Sporosarcina globispora comb. nov., Sporosarcina psy

A light-orange-coloured, facultatively anaerobic, rod-shaped bacterium (strain SW28T), which was isolated from seawater in Korea, was taxonomically studied by a polyphasic approach. This organism formed round terminal endospores in swollen sporangia. The peptidoglycan type is A4alpha, based on L-Lys-L-Ala-D-Asp. The predominant menaquinone is MK-7 and the major fatty acid is ante-C15:0. The G+C content of the DNA is 40 mol%. Phylogenetic analysis based on 16S rDNA sequences showed that strain SW28T falls within the radiation of a cluster comprising the rRNA group 2 bacilli and non-Bacillus-type organisms. Strain SW28T showed the highest degree of relatedness to the type strain of Sporosarcina ureae, sharing 96.8% 16S rDNA similarity. Levels of DNA-DNA relatedness between strain SW28T and S. ureae DSM 2281T and the type strains of some Bacillus species forming a coherent phylogenetic cluster are less than 12.5%. On the basis of phenotypic and chemotaxonomic characteristics, 16S rDNA sequence analysis and DNA-DNA relatedness data, it is proposed that strain SW28T should be placed in the genus Sporosarcina as a new species, Sporosarcina aquimarina sp. nov. The type strain is SW28T (= KCCM 41039T = JCM 10887T). From the results of the taxonomic re-evaluation, it is also proposed that Bacillus globisporus, Bacillus psychrophilus and Bacillus pasteurii be transferred to the genus Sporosarcina as Sporosarcina globispora, Sporosarcina psychrophila and Sporosarcina pasteurii, respectively.
Differential Carbohydrate Recognition by Campylobacter jejuni Strain 11168: Influences of Temperature and Growth Conditions

The pathogenic clinical strain NCTC11168 was the first Campylobacter jejuni strain to be sequenced and has been a widely used laboratory model for studying C. jejuni pathogenesis. However, continuous passaging of C. jejuni NCTC11168 has been shown to dramatically affect its colonisation potential. Glycan array analysis was performed on C. jejuni NCTC11168 using the frequently passaged, non-colonising, genome sequenced (11168-GS) and the infrequently passaged, original, virulent (11168-O) isolates grown or maintained under various conditions. Glycan structures recognised and bound by C. jejuni included terminal mannose, N-acetylneuraminic acid, galactose and fucose. Significantly, it was found that only when challenged with normal oxygen at room temperature did 11168-O consistently bind to sialic acid or terminal mannose structures, while 11168-GS bound these structures regardless of growth/maintenance conditions. Further, binding of un-capped galactose and fucosylated structures was significantly reduced when C. jejuni was maintained at 25°C under atmospheric oxygen conditions. These binding differences identified through glycan array analysis were confirmed by the ability of specific lectins to competitively inhibit the adherence of C. jejuni to a Caco-2 intestinal cell line. Our data suggests that the binding of mannose and/or N-acetylneuraminic acid may provide the initial interactions important for colonisation following environmental exposure.
Production of anti-Cryptosporidium polyclonal antibodies and standardization of direct immunofluorescence for detecting oocysts in water.

INTRODUCTION The production of anti-Cryptosporidium polyclonal antibodies and its use in direct immunofluorescence assays to determine the presence of Cryptosporidium in water are described in the present work. METHODS Two rabbits were immunized with soluble and particulate antigens from purified Cryptosporidium oocysts. The sera produced were prepared for immunoglobulin G extraction, which were then purified and conjugated with fluorescein isothiocyanate (FITC). Slides containing known amounts of oocysts were prepared to determine the sensitivity of the technique. To test the specificity, slides containing Giardia duodenalis cysts were prepared. RESULTS The conjugate was successfully used in water samples experimentally contaminated with Cryptosporidium oocysts, and it was possible to detect up to five oocysts/spot, corresponding to contamination of 250 oocysts/mL. CONCLUSIONS The three immunizations performed in the rabbits were enough to produce antibodies against Cryptosporidium, the standard direct immunofluorescence assay permitted the detection of five oocysts in 20% of the samples, and no cross-reaction with Giardia duodenalis cysts occurred.

Uptake, Accumulation and Toxicity of Silver Nanoparticle in Autotrophic Plants, and Heterotrophic Microbes: A Concentric Review

Nanotechnology is a cutting-edge field of science with the potential to revolutionize today’s technological advances including industrial applications. It is being utilized for the welfare of mankind; but at the same time, the unprecedented use and uncontrolled release of nanomaterials into the environment poses enormous threat to living organisms. Silver nanoparticles (AgNPs) are used in several industries and its continuous release may hamper many physiological and biochemical processes in the living organisms including autotrophs and heterotrophs. The present review gives a concentric know-how of the effects of AgNPs on the lower and higher autotrophic plants as well as on heterotrophic microbes so as to have better understanding of the differences in effects among these two groups. It also focuses on the mechanism of uptake, translocation, accumulation in the plants and microbes, and resulting toxicity as well as tolerance mechanisms by which these microorganisms are able to survive and reduce the effects of AgNPs. This review differentiates the impact of silver nanoparticles at various levels between autotrophs and heterotrophs and signifies the prevailing tolerance mechanisms. With this background, a comprehensive idea can be made with respect to the influence of AgNPs on lower and higher autotrophic plants together with heterotrophic microbes and new insights can be generated for the researchers to understand the toxicity and tolerance mechanisms of AgNPs in plants and microbes.
Evaluating verbose query processing techniques

Verbose or long queries are a small but significant part of the query stream in web search, and are common in other applications such as collaborative question answering (CQA). Current search engines perform well with keyword queries but are not, in general, effective for verbose queries. In this paper, we examine query processing techniques which can be applied to verbose queries prior to submission to a search engine in order to improve the search engine's results. We focus on verbose queries that have sentence-like structure, but are not simple "wh-" questions, and assume the search engine is a "black box. " We evaluated the output of two search engines using queries from a CQA service and our results show that, among a broad range of techniques, the most effective approach is to simply reduce the length of the query. This can be achieved effectively by removing "stop structure" instead of only stop words. We show that the process of learning and removing stop structure from a query can be effectively automated.
Paediatric regional anaesthesia, a survey of practice in the United Kingdom.

BACKGROUND A variety of techniques and drugs, many unlicensed, is used in paediatric regional anaesthesia. This study is the first to survey paediatric anaesthetists about the techniques and drugs used in paediatric regional anaesthesia. The aim is to provide a record and benchmark of UK practice. METHODS A postal questionnaire was sent to all members of the Association of Paediatric Anaesthetists residing in the UK. Information was requested on the type of hospital worked in, years of practice, paediatric anaesthesia workload, regional anaesthesia techniques used, and drugs used in regional anaesthesia. RESULTS A total of 220 responses from 264 questionnaires (83.3%) were received. Of these respondents, 155 (70%) practised paediatric anaesthesia as more than 50% of their workload, and 10 had retired or returned blank forms. Two hundred and two of 210 (96%) use caudal anaesthesia and 151 (72%) use caudal, epidural and peripheral block. One hundred and ninety-two of 210 (91%) have no lower age limit for using caudal anaesthesia. One hundred and twenty-three of 210 anaesthetists (58%) used adjuvants with local anaesthetics in caudal block, the most common being fentanyl [44/210 (21%)], clonidine [55/210 (26%)], diamorphine [27/210 (13%)] and ketamine [67/210 (32%)]. Those working in specialist centres or teaching hospitals or who had a greater paediatric anaesthesia workload were more likely to use a greater variety of regional anaesthesia techniques. CONCLUSIONS Caudal anaesthesia is widely used for patients of all ages by almost all practitioners. Most anaesthetists at all hospital types and experience levels use adjuvants with local anaesthetics when performing caudal anaesthesia. Those with more experience in paediatric anaesthesia and those in specialist centres commonly use other neuraxial and peripheral block techniques.
Differences in swimming speed on short course and long course for female and male breaststroke swimmers: A comparison of swimmers at national and international level

Background: The aims were to examine (i) the difference in swimming speed in breaststroke swimmers between short (SC) and long course (LC) and (ii) the change in swimming speed across years for elite female and male swimmers competing at national and international level. Methods: Swimming speed of breaststroke swimmers at national level (i.e. athletes listed in Swiss swimming high score list between 2000 and 2011) and at international level (i.e. finalists of World Championships between 2001 and 2012) were analyzed for three course distances (i.e. 50m, 100m and 200m) using linear regression analyses and analysis of variance. Results: Swimming speed was faster in SC than in LC in 50m (1.8-2.6%), 100m (2.2-3.6%) and 200m (2.6-4.2 %), respectively. Swimming speed increased between 1.2% and 5.2% both for SC and LC across years, independently of the sex and the distance. For all distances, the sex difference was greater in LC than in SC. Mean values for the sex difference in swimming speed at national level were 12.1% in SC versus 11.9% in LC for 50 m, 11.9% in SC versus 11.3% in LC for 100m and 11.0% in SC versus 10.7% in LC for 200m, with significant difference only for 200m LC (p=0.03). Mean values for sex difference in swimming speed at international level were 13.3% in SC versus 12.7% in LC for 50m, 12.6% in SC versus 11.9% in LC for 100m and 12.1% in SC versus 11.2% in LC for 200m, only with significance for 100m SC (p=0.01). Conclusion: Elite breaststroke swimmers were ∼3% faster on SC compared to LC. The sex difference in breaststroke swimming speed from 50m to 200m events was ~11% (with significance at national level on 200m LC and on international level on 100m SC) but appeared slightly greater in LC compared to SC.
