Topic distillation using hierarchy concept tree

In this paper, we propose a new approach for topic distillation on World Wide Web. Topic distillation is to find quality documents related to the user query topic. Our approach is based on Bharat's topic distillation algorithm [1]. We present the analysis of hyperlink graph structure using hierarchy concept tree to solve the mixed hubs problem that is also remained in the Bharat's algorithm. For assigning better weights to hyperlinks which point to relevant documents among hyperlinks in a document, we try to find the relationship in documents connected by hyperlinks using content analysis and we assign weights to hyperlinks based on the relationship. We evaluated this algorithm using 50 topics on WT10g corpus and obtained improved results.
DOMProxy: enabling dynamic-content front-end Web caching

Proxy caching is a commonly accepted methodology used to reduce Internet traffic, decrease back-end related user delays, and generally improve Web performance. Nevertheless, it seems to be inadequate when it comes to caching dynamic Web pages, due to their low degree of reusability and strong dependency on the back-end site infrastructure. In order to overcome these drawbacks we present DOMProxy (dynamic objects manager proxy), a new proxy architecture that enables front-end Web caching for dynamically generated Web pages. Instead of caching Web pages produced dynamically or their fragments, the proposed architecture provides methods for "caching" their generation process. This is achieved by caching both the applications and the back-end data content that are used to create dynamic Web pages. We discuss the new challenges and issues raised by this approach, with special emphasis on the caching and manipulation of different types of Web objects at a front-end caching point.
Video games as a multifaceted medium: a review of quantitative social science research on video games and a typology of video game research approaches

Although there is a vast and useful body of quantitative social science research dealing with the socialrole and impact of video games, it is difficult to compare studies dealing with various dimensions ofvideo games because they are informed by different perspectives and assumptions, employ differentmethodologies, and address different problems. Studies focusing on different social dimensions ofvideo games can produce varied findings about gamesâ€™ social function that are often difficult to reconcileâ€”or even contradictory. Research is also often categorized by topic area, rendering a comprehensiveview of video gamesâ€™ social role across topic areas difficult. This interpretive review presentsa novel typology of four identified approaches that categorize much of the quantitative social sciencevideo game research conducted to date: â€œvideo games as stimulus,â€ â€œvideo games as avocation,â€â€œvideo games as skill,â€ and â€œvideo games as social environment. â€ This typology is useful because itprovides an organizational structure within which the large and growing number of studies on videogames can be categorized, guiding comparisons between studies on different research topics and aidinga more comprehensive understanding of video gamesâ€™ social role. Categorizing the different approachesto video game research provides a useful heuristic for those critiquing and expanding thatresearch, as well as an understandable entry point for scholars new to video game research. Further,and perhaps more importantly, the typology indicates when topics should be explored using differentapproaches than usual to shed new light on the topic areas. Lastly, the typology exposes the conceptualdisconnects between the different approaches to video game research, allowing researchers toconsider new ways to bridge gaps between the different approachesâ€™ strengths and limitations withnovel methods.
Landscape’s physiognomic structure: conceptual development and practical applications

Abstract The past decade has seen an increased interest in approaches for the identification and assessment of landscapes, which has been, in part, a response to the European Landscape Convention (ELC). In this article, we review landscape physiognomy, an important component of the Polish approach to the assessment and identification of its landscape. We address the relevance of physiognomy both in relation to the ELC and to the landscape character assessments approach, and then explore the theoretical basis of landscape physiognomic structure. We also expand the existing classification of landscape interiors; this is followed by combining three approaches: (1) physical geography in the field of comprehensive classification of natural landscapes; (2) landscape ecology studies on the spatial structure of land cover patches against the ‘landscape matrix’ and (3) the theory of landscape interiors. Presented ideas create the outline of the concept of landscape’s physiognomic structure.
Controlling Wild Bodies Using Discrete Transition Systems

This paper proposes methods for achieving basic tasks such as navigation, patrolling, herding, and coverage by exploiting the wild motions of very simple bodies in the environment. Bodies move within regions that are connected by gates that enforce specific rules of passage. This leads to a hybrid systems approach in which the behaviors define a discrete transition system. Tasks can even be specified using a Linear Temporal Logic (LTL) formula and are converted into a multibody implementation that satisfies the formula. Common issues such as dynamical system modeling, precise state estimation, and state feedback are avoided. The method is demonstrated in a series of experiments that manipulate the flow of weasel balls (without the weasels) and Hexbug Nano vibrating bugs.
“Getting Help for Yourself is a Way of Helping Your Baby: ” Fathers’ Experiences of Support for Mental Health and Parenting in the Perinatal Period

The need for services targeting fathers in the perinatal period is increasingly apparent. To maximize engagement, such interventions need to be father focused, but men’s experiences and needs around support have not been adequately examined. Therefore, the aims of this qualitative study were to explore men’s experiences of seeking support for their mental health and parenting in the perinatal period, and identify their specific support needs during this time. Australian fathers (N = 20) who were expecting or parenting an infant less than 2 years of age participated in individual semistructured face-to-face or telephone interviews. Thematic content analysis was used to analyze the data. Five broad themes were explored: experiences of support, support needs, barriers to support, facilitators to support, and timing of support. Several subthemes were identified within each category, illustrating a diverse range of issues that fathers experience across the perinatal period. The findings have implications for our understanding of fathers’ help-seeking behaviors, their perinatal support needs and for the development of resources, services, and interventions aiming to engage fathers in maternity health services.
PROPHET : Tool Infrastructure To Support Program Comprehension Experiments

Program comprehension is an important human factor in software engineering. To evaluate and improve it, controlled experiments are usually necessary, which, however, require a lot of effort. To support researchers in planning and conducting program-comprehension experiments, we developed the extensible tool PROPHET. It can fulfill the most common requirements of program-comprehension experiments published in the last five years. Furthermore, PROPHET provides an extensible architecture, so that new requirements can be easily implemented. Keywords-program comprehension; experiments; tool support; prophet
In Vitro and Ex Vivo Testing of Tenofovir Shows It Is Effective As an HIV-1 Microbicide

Background Tenofovir gel has entered into clinical trials for use as a topical microbicide to prevent HIV-1 infection but has no published data regarding pre-clinical testing using in vitro and ex vivo models. To validate our findings with on-going clinical trial results, we evaluated topical tenofovir gel for safety and efficacy. We also modeled systemic application of tenofovir for efficacy. Methods and Findings Formulation assessment of tenofovir gel included osmolality, viscosity, in vitro release, and permeability testing. Safety was evaluated by measuring the effect on the viability of vaginal flora, PBMCs, epithelial cells, and ectocervical and colorectal explant tissues. For efficacy testing, PBMCs were cultured with tenofovir or vehicle control gels and HIV-1 representing subtypes A, B, and C. Additionally, polarized ectocervical and colorectal explant cultures were treated apically with either gel. Tenofovir was added basolaterally to simulate systemic application. All tissues were challenged with HIV-1 applied apically. Infection was assessed by measuring p24 by ELISA on collected supernatants and immunohistochemistry for ectocervical explants. Formulation testing showed the tenofovir and vehicle control gels were >10 times isosmolar. Permeability through ectocervical tissue was variable but in all cases the receptor compartment drug concentration reached levels that inhibit HIV-1 infection in vitro. The gels were non-toxic toward vaginal flora, PBMCs, or epithelial cells. A transient reduction in epithelial monolayer integrity and epithelial fracture for ectocervical and colorectal explants was noted and likely due to the hyperosmolar nature of the formulation. Tenofovir gel prevented HIV-1 infection of PBMCs regardless of HIV-1 subtype. Topical and systemic tenofovir were effective at preventing HIV-1 infection of explant cultures. Conclusions These studies provide a mechanism for pre-clinical prediction of safety and efficacy of formulated microbicides. Tenofovir was effective against HIV-1 infection in our algorithm. These data support the use of tenofovir for pre-exposure prophylaxis.
O PERFIL DOS ESTUDANTES UNIVERSITÁRIOS NA DECISÃO DE TEREM RELAÇÕES SEXUAIS

EnglishThe HIV infection rates continue to rise among heterosexual young adults due to inconsistent condom use. In order to be able to design interventions to increase condom use we need to understand how young adults decide to have sexual intercourse. Nevertheless, Jones and Nisbett (1971) refer that individuals impair in the ability to perceive the motives underlying their behaviour.According to Weiderman (1999) individuals base their answers upon the factors they think that promote behavior. However, when a decision is taken, the variables that contribute to it can be different or have different importance from those rationally point out. To avoid measure the beliefs over the decision to use condoms, we used the policy capture methodology to understand how individuals decide to have sexual relations since this technique allow us to measure individual judgment base in multidimensional stimulus using a linear model (Brehmer & Brehmer, 1988). The scenarios included stimulus concerning the type of relationship, alcohol consumption, attitudes towards condoms, ability to negotiate condoms with partner and condoms availability. The individuals where clustered according to their answers to scenarios. Different types of decision emerged pointing out the necessity to developed different interventions according to the individuals’ method of decision portuguesA infeccao por VIH continua a aumentar nos jovens adultos heterossexuais devido a inconsistencia no uso do preservativo. Para que as intervencoes sejam capazes de promover uma utilizacao consistente do preservativo e necessario compreender como os jovens adultos decidem ter relacoes sexuais. Contudo, Jones e Nisbett (1971) referem que os individuos tem dificuldade em perceber os motivos subjacentes ao seu comportamento e, de acordo com Weiderman (1999) estes baseiam as suas respostas nos factores que pensam promover o comportamento. No entanto, quando se toma uma decisao, as variaveis que contribuem podem ser diferentes ou ter importâncias diferentes daquelas racionalmente referidas. Para evitar medir as crencas relativas a decisao de usar preservativos, utilizamos a metodologia de captacao de comportamento para compreender como os individuos decidem ter relacoes sexuais. Esta tecnica permite medir o julgamento individual com base em estimulos multidimensionais atraves de um modelo linear (Brehmer & Brehmer, 1988). Os cenarios incluem estimulos relativos ao tipo de relacao, consumo de alcool, atitudes face ao preservativo, negociacao e disponibilidade do preservativo. Os individuos foram agrupados atraves das suas respostas e diferentes tipos de decisao emergiram sugerindo a necessidade de desenvolver diferentes tipos de intervencao de acordo com o tipo de decisao.
Vaccination with DNA Encoding Truncated Enterohemorrhagic Escherichia coli (EHEC) Factor for Adherence-1 Gene (efa-1′) Confers Protective Immunity to Mice Infected with E. coli O157:H7

Enterohemorrhagic Escherichia coli (EHEC) O157:H7 is the predominant causative agent of hemorrhagic colitis in humans and is the cause of haemolytic uraemic syndrome and other illnesses. Cattle have been implicated as the main reservoir of this organism. Here, we evaluated the immunogenicity and protective efficacy of a DNA vaccine encoding conserved sequences of truncated EHEC factor for adherence-1 (efa-1′) in a mouse model. Intranasal administration of plasmid DNA carrying the efa-1′ gene (pVAXefa-1′) into C57BL/6 mice elicited both humoral and cellular immune responses. In animals immunized with pVAXefa-1′, EHEC-secreted protein-specific IgM and IgG antibodies were detected in sera at day 45. Anti-EHEC-secreted protein sIgA was also detected in nasal and bronchoalveolar lavages. In addition, antigen-specific T-cell-proliferation, IL-10, and IFN-γ were observed upon re-stimulation with either heat-killed bacteria or EHEC-secreted proteins. Vaccinated animals were also protected against challenge with E. coli O157:H7 strain EDL933. These results suggest that DNA vaccine encoding efa-1′ have therapeutic potential in interventions against EHEC infections. This approach could lead to a new strategy in the production of vaccines that prevent infections in cattle.
Learning complex linguistic structure: The Simple Recurrent Network (SRN) as a model of nonadjacent dependency learning

Higher-order syntactic structure is a hallmark of language, contributing to its expressive power, but also making it more difficult to learn. One such example is the nonadjacent dependency, where one element predicts another element, but at a distance. The present work reviews behavioral studies of nonadjacent dependency learning in artificial grammars, focusing on a few critical studies that highlight important properties of language. In this work, we explain behavioral performance in those studies within a single theoretical framework, the connectionist simple recurrent network (SRN). Five simulations were performed, showing that the SRN captures the qualitative patterns of human performance in these learning tasks. Further, examination of why the SRN succeeds provides additional insights into how people may learn language. One important conclusion is that the SRN, like people, performs dramatically better in situations where the learning situation is made more realistic, incorporating cues like meaning and variability that children have when learning natural languages.

A survey of surface braid groups and the lower algebraic K-theory of their group rings

We give a survey of the theory of surface braid groups and the lower algebraic K-theory of their group rings. We recall several definitions and describe various properties of surface braid groups, such as the existence of torsion, orderability, linearity, and their relation both with mapping class groups and with the homotopy groups of the 2-sphere. The braid groups of the 2-sphere and the real projective plane are of particular interest because they possess elements of finite order, and we discuss in detail their torsion and the classification of their finite and virtually cyclic subgroups. Finally, we outline the methods used to study the lower algebraic K-theory of the group rings of surface braid groups, highlighting recent results concerning the braid groups of the 2-sphere and the real projective plane.
Treating Anxiety with Exercise

Anxiety is an issue that plagues virtually everyone at some point in their life. It is the overwhelming feeling of nervousness and pressure sometimes created by perceived insurmountable responsibilities. In fact, it can become so serious that people require additional help in dealing with what has become a very common disorder. Patients suffering from severe anxiety require counseling from a professional and often, are prescribed medicines to help ease their anxiety. One can also try to reduce anxiety by doing enjoyable activities that involve movement, such as yoga and dance.
Leaf Vein Extraction Using a Combined Operation of Mathematical Morphology

The type of the leaf vein can be a useful parameter in automatic identification of plant species. Leaf vein extraction is the precondition of discriminating the leaf vein type. In this paper a new method is presented for leaf vein extraction based on mathematical morphology. Firstly, the color image of the plant leaf is transformed to gray image according to the hue and intensity information. Secondly, a combined operation of mathematical morphology is applied to the image to eliminate the color overlap between the whole leaf vein and the whole background. Thirdly, image segmentation is performed with OSTU method. Finally, the leaf vein can be got after some processing on details. Experiments have been conducted with several images and the results show the effectiveness of the method. The basic idea of the method is also applicable to other linear objects extraction.
deepBase v2.0: identification, expression, evolution and function of small RNAs, LncRNAs and circular RNAs from deep-sequencing data

Small non-coding RNAs (e.g. miRNAs) and long non-coding RNAs (e.g. lincRNAs and circRNAs) are emerging as key regulators of various cellular processes. However, only a very small fraction of these enigmatic RNAs have been well functionally characterized. In this study, we describe deepBase v2.0 (http://biocenter.sysu.edu.cn/deepBase/), an updated platform, to decode evolution, expression patterns and functions of diverse ncRNAs across 19 species. deepBase v2.0 has been updated to provide the most comprehensive collection of ncRNA-derived small RNAs generated from 588 sRNA-Seq datasets. Moreover, we developed a pipeline named lncSeeker to identify 176 680 high-confidence lncRNAs from 14 species. Temporal and spatial expression patterns of various ncRNAs were profiled. We identified approximately 24 280 primate-specific, 5193 rodent-specific lncRNAs, and 55 highly conserved lncRNA orthologs between human and zebrafish. We annotated 14 867 human circRNAs, 1260 of which are orthologous to mouse circRNAs. By combining expression profiles and functional genomic annotations, we developed lncFunction web-server to predict the function of lncRNAs based on protein-lncRNA co-expression networks. This study is expected to provide considerable resources to facilitate future experimental studies and to uncover ncRNA functions.
A Multiple View Interactive Environment to Support MATLAB and GNU/Octave Program Comprehension

Program comprehension plays an important role in Software Engineering. In fact, many of the software lifecycle activities depend on program comprehension. Despite the importance of MATLAB and Octave programing languages in the Engineering and Statistical communities, little attention has been paid to the conception, implementation and characterization of tools and techniques for the comprehension of programs written in these languages. Considering this scenario, this paper presents a Multiple View Interactive Environment (MVIE) called Oct Miner that supports the comprehension of programs developed in the aforementioned languages. Oct Miner provides a set of coordinated visual metaphors that can be adjusted in accordance with the comprehension goals. An example is presented to illustrate the main functionalities of Oct Miner in a real scenario of program comprehension.
Trial report on self-organizing map based analysis tool for radio networks [GSM applications]

Telecommunications networks move towards wireless applications and service and business driven network management. Operators provide new services on different access technologies, in a multi-technology environment. This shift in abstraction level towards services, away from technology and network element management, requires new tools and methods to support the operational tasks, of which service monitoring and traffic analysis is an especially important area. In this paper, the concept of a neural network based tool that aids the operators in detecting the quality of end-user experience (QoE) is introduced.
