Cytological Anal Squamous Intraepithelial Lesions Associated with Anal High-Risk Human Papillomavirus Infections among Men Who Have Sex with Men in Northern Thailand

Background Anal cancer, one of human papillomavirus (HPV) related malignancies, has increased in recent decades, particularly among men who have sex with men (MSM) and HIV-infected (HIV+) persons. We aimed to explore the prevalence of anal squamous intraepithelial lesions (ASIL) using Papanicolau (Pap) screening among MSM in northern Thailand and its associated factors. Methods Two hundreds MSM aged ≥18 years reporting receptive anal intercourse in the prior 6 months were recruited from July 2012 through January 2013. Medical history and behavioral data were collected by staff interview and computer-assisted self interview. Anal Pap smear, HPV genotyping, and HIV testing were performed. Two pathologists blinded to HPV and HIV status reported cytologic results by Bethesda classification. Results Mean age was 27.2 years (range 18–54). Overall, 86 (43.0%) had ASIL: 28 (14.2%) with atypical cells of undetermined significance (ASCUS), 1 (0.5%) with atypical squamous cells—cannot exclude high-grade squamous intraepithelial lesion (ASC-H), 56 (28.4%) with low-grade squamous intraepithelial lesion (LSIL), and 1 (0.5%) with high-grade squamous intraepithelial lesion (HSIL). ASIL was associated by univariate analysis (p ≤0.05) with older age, gender identity other than bisexual (i.e., gay men and transgender women), rectal douching, anal symptoms, genital warts, HIV positivity, and high-risk-HPV infection. However, on multiple logistic regression ASIL was associated only with high-risk HPV type (p = 0.002) and HIV infection (p = 0.01). Conclusions ASIL is quite common in high-risk MSM in northern Thailand and is associated with high-risk HPV types and HIV infection. Routine anal Pap screening should be considered, given the high frequency of ASIL, particularly in the HIV+. High resolution anoscopy (HRA), not done here, should be to confirm PAP smears whose sensitivity and specificity are quite variable. Timely HPV vaccination should be considered for this population.
Conditional Functional Dependencies for Data Cleaning

We propose a class of constraints, referred to as conditional functional dependencies (CFDs), and study their applications in data cleaning. In contrast to traditional functional dependencies (FDs) that were developed mainly for schema design, CFDs aim at capturing the consistency of data by incorporating bindings of semantic ally related values. For CFDs we provide an inference system analogous to Armstrong's axioms for FDs, as well as consistency analysis. Since CFDs allow data bindings, a large number of individual constraints may hold on a table, complicating detection of constraint violations. We develop techniques for detecting CFD violations in SQL as well as novel techniques for checking multiple constraints in a single query. We experimentally evaluate the performance of our CFD-based methods for inconsistency detection. This not only yields a constraint theory for CFDs but is also a step toward a practical constraint-based method for improving data quality.
TweetBuzz : Identifying Buzzwords in a Domain

Since past few years, social media has become an integral part of modern society. The user generated social data, in the form of tweets (microblogs), wall-postings, blogs, video blogs (vlogs), etc. contains great wealth of information and can be exploited to explore any field including the current affairs worldwide. In this paper, we introduce 'TweetBuzz', an application which uses Twitter [10] data, i.e., tweets, to analyze the current buzzwords, the topics which are being highly discussed, in a particular domain. This system can be applied to any area in general, provided we have its knowledge base; and we also show that having some specific knowledge about the domain can also help in improving the accuracy of the system. In our case, we have chosen 'Hollywood movies' as our area, and using a large set of tweets, we try to find out what all movies in a specific genre are popular among Twitter users.
Anthropometric and Cardiovascular Variables of Elite Athletes

Summary Synchronized swimming and aerobic gymnastics are competitive sports that have grown in popularity throughout the Slovakia and around the world. Unfortunately, a paucity of research exists either on anthropometric and physiological characteristics or physical benefits of these sports. The present study examined anthropometric and cardiovascular characteristics of control group - CO (n = 10) in comparison to competitive synchronized swimmers - SS (n = 11) and aerobic gymnasts - AG (n = 10) between the ages of 13 and 25 years. The physical measures were assessed per the protocols in the following order: height (BH), weight (BW), body mass index (BMI), and % body fat (% BF). The measurements of maximal oxygen consumption (VO2max) and maximum heart rate (HRmax) were examined by spiroergometry via COSMED K4b2. All measurements were collected by trained data collection staff. An analysis of variance (Kruskal - Wallis) with a Mann-Whitney U test for the significant effect among the three groups showed that aerobic gymnasts were taller than synchronized swimmers and control group (p = .02). Training and conditioning requirements specific for the two athletic groups caused that AG and SS have higher level of VO2max (p = .02) and VO2max.kg-1 (p = .00), and also lower level of the body weight (p= .01), BMI (p = .01) and the % BF (p = .00). These findings confirm that selected parameters are considered the bases for success in elite sports. This information could also help to design specific training and evaluate the adaptation to training stimuli with the aim to maximize sport performance.
Why Does Educational Attainment Differ Across U.S. States?

The fraction of persons holding a college degree differs nearly two-fold across U.S. states. This paper documents data related to state educational attainment differences and explores possible explanations. It shows that highly educated states employ skillbiased technologies, specialize in skill-intensive industries, but do not pay lower skill premia than do less educated states. Moreover, measures of urbanization and population density are positively related to educational attainment. Theories based on agglomeration economies offer natural explanations for these observations.
Emergent Dynamics of Fast Ripples in the Epileptic Hippocampus

Fast ripples are a type of transient high-frequency oscillations recorded from the epileptogenic regions of the hippocampus and the temporal cortex of epileptic humans and rodents. These events presumably reflect hypersynchronous bursting of pyramidal cells. However, the oscillatory spectral content of fast ripples varies from 250 to 800 Hz, well above the maximal firing frequency of most hippocampal pyramidal neurons. How such high-frequency oscillations are generated is therefore unclear. Here, we combine computational simulations of fast ripples with multisite and juxtacellular recordings in vivo to examine the underlying mechanisms in the hippocampus of epileptic rats. We show that populations of bursting cells firing individually at 100–400 Hz can create fast ripples according to two main firing regimes: (1) in-phase synchronous firing resulting in “pure” fast ripples characterized by single spectral peaks that reflect single-cell behavior and (2) out-of-phase firing that results in “emergent” fast ripples. Using simulations, we found that fast ripples generated under these two different regimes can be quantitatively separated by their spectral characteristics, and we took advantage of this separability to examine their dynamics in vivo. We found that in-phase firing can reach frequencies up to 300 Hz in the CA1 and up to 400 Hz in the dentate gyrus. The organization of out-of-phase firing is determined by firing delays between cells discharging at low frequencies. The two firing regimes compete dynamically, alternating randomly from one fast ripple event to the next, and they reflect the functional dynamic organization of the different regions of the hippocampus.
Palm print identification using fractional coefficient of transformed edge palm images with Cosine, Haar and Kekre transform

Paper presents performance comparison of palm print identification techniques based on fractional coefficients of transformed palm print edge image using three transforms namely Cosine, Haar and Kekre. In transform domain, the energy of image gets concentrated towards low frequency region; this characteristic of image transforms is used here to reduce the feature vector size of palm print images by selecting these low frequency coefficients in transformed edge images. Three image transforms applied on palm print edge image and 7 ways of taking fractional coefficients along with five different edge detection methods give total 105 variation of proposed palm print identification method. Experimentation is done on a test bed of 1000 palm print images (500 left and 500 right). Genuine acceptance rate is considered for performance comparison. The experimental results in Cosine and Haar transform have shown performance improvement in palm print identification using fractional coefficients of transformed images. In all edge detection methods, canny is proven to be better. In all Cosine transform gives best performance having maximum GAR value for canny edge detection method with 0.097% of fractional coefficients considering both left and right palm print images.
Occupancy-Elevation Grid Mapping from Stereo Vision

This paper proposes an alternative environment mapping method for accurate robotic navigation based on 3D information. Typical techniques for 3D mapping using occupancy grid require intensive computational workloads to both build and store the map. We introduce an Occupancy-Elevation Grid (OEG) mapping based on visual range data, which is a discrete mapping approach where each cell represents the occupancy probability, the elevation of the terrain and its variance. This representation allows a mobile robot to know if a space in its environment is occupied by an obstacle and the elevation of such obstacle, thus, it can decide if it is possible to traverse the obstacle. The resulting maps allow the execution of tasks like decision making for autonomous navigation, exploration, localization and path planning. Experiments carried out with a real mobile robot equipped by a stereo vision system demonstrate that the proposed approach yields useful maps for autonomous robust navigation.
Image interpolation using visual attention model and particle swarm optimization

In this study, a new edge-directed image interpolation approach using visual attention model and particle swarm optimization (PSO) is proposed. First, a high-quality saliency map of an image to be interpolated is generated by the proposed visual attention model in an effective manner. Then, based on the saliency map, bilinear interpolation and the proposed PSO interpolation are employed for non-saliency blocks (non-ROIs) and saliency blocks (ROIs), respectively, to obtain the final interpolation results. The proposed approach is applicable for image interpolation with arbitrary magnification factors (MFs). Based on the experimental results obtained in this study, the interpolation results of the proposed approach are better than those of three comparison methods.
A contract-extended push-pull-clone model

In the push-pull-clone collaborative editing model widely used in distributed version control systems users replicate shared data, modify it and redistribute modified versions of this data without the need of a central authority. However, in this model no usage restriction mechanism is proposed to control what users can do with the data after it has been released to them. In this paper we extended the push-pull-clone model with contracts that express usage restrictions and that are checked a posteriori by users when they receive the modified data. We propose a merging algorithm that deals not only with modifications on data but also with contracts. A log-auditing protocol is used to detect users who do not respect contracts and to adjust user trust levels. Our proposed contract-based model has been implemented and evaluated by using PeerSim simulator.
Secularization in the Long 1960s: Numerating Religion in Britain

The chapter sets the scene in three respects. It reviews the historiography of British religious change in the long 1960s, with particular reference to Callum Brown’s thesis of a gendered revolutionary secularization commencing in 1963, and the cautious or critical reactions to this interpretation of other historians and sociologists. It introduces the statistical sources to be used in evaluating such competing claims, noting any methodological limitations or availability issues, the principal data collecting agencies being the state, faith communities, opinion pollsters, and academic social scientists. Finally, it defines the parameters of the work, considering alternative definitions of the 1960s, ultimately opting for wide chronological limits (mostly presenting statistics for 1955-80), and explaining the spatial, demographic, and empirical scope (and thus any topics consciously excluded from the terms of reference).
Core Competencies Development among Science and Technology (S&T) College Students and New Graduates

Employers and societies increasingly ask for competent and ready to work graduates, endowed with a certain amount of capabilities and competencies when entering the workforce. Whereas the need for highly skilled worker has been climbing, the discrepancy between competencies of graduates and qualifications searched by employers continue to be a serious concern among various nations [1,24]. The main issue addressed by the present study is: “Is science and technology (S&T) students and new graduates’ development of core competencies influenced by their prior perception of importance of these competencies? And does the development of these core competencies guarantee their fitness for purpose in terms of entering into the workforce? ” Findings revealed that S&T students and new graduates’ experience at the institution have developed all the seven core competencies under investigation in the present research and that the development of core competencies is not always influenced by prior perception of importance. With respect to the fitness for purpose, findings show that S&T students and new graduates perceived their preparedness for the workplace close to “more than adequate preparation for being an expert in my field of S&T”. This finding confirms the view of “fitness for purpose” explanation as a requirement of the higher education.
Evaluating the Quality of Service for a Satellite Based Content Delivery Network

—In the past years content delivery networks (CDNs) have become increasingly popular as they bypass the contended Internet and deliver content to their paying customers with higher quality of service (QoS). Satellite based CDNs additionally exploit the advantage of satellite multicast and broadcast, being able to deliver the same content to an arbitrary number of points of presence (PoPs) in its footprint. Although many future CDNs will use satellites, little is known about the QoS as perceived by end users of such a network and how to measure it. In this paper we present a methodology for evaluating the QoS of a satellite based CDN for the European IST project CODIS. Designed as a professional CDN transporting MPEG-2 and MPEG-4 based multimedia presentations for content providers, broadcasters, and ISPs, the network will use the satellite STENTOR, containing an onboard MPEG-TS multiplexer. The methodology is centered around the QoS perceived by network end users.
An Exploration of the Factors that Influence Brazilian Students' Fluency of English: A Case Study

Although English fluency is necessary for Brazilians’ participation in the global marketplace, little is known about how English fluency is acquired in the context of the Brazilian educational system. The purpose of this holistic single-case study was to identify and understand how English fluency was acquired by studying the child, the family, and the school interactions that contributed to Brazilian students’ development of English. The primary research question that supported the purpose of this holistic singlecase study was what perceived influences act within and on the students’ language acquisition to acquire English fluency? Middle school students with high English fluency in a private school in Goiânia, Goias, Brazil, were studied to attain evidence of the influences that supported their success in acquiring fluency in the English language. Interviews, interview transcriptions, tape-recordings, document analysis, membercheck interviews, and researcher memos were coded and analyzed through the qualitative data analysis software, NVivo 10.0 for Mac Beta. Seven themes of external influences (family and teacher) and two themes of internal influences (within the child) were identified. The seven themes of external factors that emerged from the data were the following: (1) English lessons are a Priority in Extracurricular Activities, (2) Technology Use is Fundamental, (3) Parents Participate in the Learning Experience, (4) Contact with Culture and Native Speakers Advances English, (5) Parents Set High Standards, (6) the Curriculum, and (7) Teachers’ Competency Influences English Fluency. One sub-theme of external factors was Parents Motivate Fluency through Example. Two themes related to internal factors were identified: (1) Students are Naturally Interested, and (2) the Students Like Learning. The results revealed that when positive didactic influences between the child and the family, and the child and the teachers were evident, the child achieved successful English fluency.
Probing dynamics of HIV-1 nucleocapsid protein/target hexanucleotide complexes by 2-aminopurine

The nucleocapsid protein (NC) plays an important role in HIV-1, mainly through interactions with the genomic RNA and its DNA copies. Though the structures of several complexes of NC with oligonucleotides (ODNs) are known, detailed information on the ODN dynamics in the complexes is missing. To address this, we investigated the steady state and time-resolved fluorescence properties of 2-aminopurine (2Ap), a fluorescent adenine analog introduced at positions 2 and 5 of AACGCC and AATGCC sequences. In the absence of NC, 2Ap fluorescence was strongly quenched in the flexible ODNs, mainly through picosecond to nanosecond dynamic quenching by its neighboring bases. NC strongly restricted the ODN flexibility and 2Ap local mobility, impeding the collisions of 2Ap with its neighbors and thus, reducing its dynamic quenching. Phe16→Ala and Trp37→Leu mutations largely decreased the ability of NC to affect the local dynamics of 2Ap at positions 2 and 5, respectively, while a fingerless NC was totally ineffective. The restriction of 2Ap local mobility was thus associated with the NC hydrophobic platform at the top of the folded fingers. Since this platform supports the NC chaperone properties, the restriction of the local mobility of the bases is likely a mechanistic component of these properties.
Faster all-pairs shortest paths via circuit complexity

We present a new randomized method for computing the min-plus product (a.k.a., tropical product) of two n × n matrices, yielding a faster algorithm for solving the all-pairs shortest path problem (APSP) in dense n-node directed graphs with arbitrary edge weights. On the real RAM, where additions and comparisons of reals are unit cost (but all other operations have typical logarithmic cost), the algorithm runs in time [EQUATION] and is correct with high probability. On the word RAM, the algorithm runs in [EQUATION] + n2+o(1) logM time for edge weights in ([0,M]∩Z)∪{∞}. Prior algorithms took either O(n3/logc n) time for various c ≤ 2, or O(Mαnβ) time for various α > 0 and β > 2. The new algorithm applies a tool from circuit complexity, namely the Razborov-Smolensky polynomials for approximately representing AC0[p] circuits, to efficiently reduce a matrix product over the (min, +) algebra to a relatively small number of rectangular matrix products over F2, each of which are computable using a particularly efficient method due to Coppersmith. We also give a deterministic version of the algorithm running in n[EQUATION] time for some δ > 0, which utilizes the Yao-Beigel-Tarui translation of AC0[m] circuits into "nice" depth-two circuits.
Semisupervised Nonnegative Matrix Factorization for learning the semantics

In real world there are a lot of unlabeled data, and relatively few labeled data. Unlabeled data help to learn a statistical model that can fully describe the global property of data, while labeled data help to minimize the gap between the statistical property and human beings' perception, i.e. labeled data can help to learn the semantics. Nonnegative Matrix Factorization is a popular technique in data analysis, since a lot of real world data are nonnegative. However, traditional NMF is an unsupervised learning algorithm, which means that it cannot make use of the label information. To enable NMF to make use of both labeled and unlabeled data samples, we propose a novel semisupervised Nonnegative Matrix Factorization technique for learning the semantics. The proposed algorithm extracts prior information from the labeled data, and then uses it to guide the later processing. Experimental results with different settings prove the efficacy of the proposed algorithm.
Do Organizational Practices Matter in Role Stress Processes? A Study of Direct and Moderating Effects for Marketing-Oriented Boundary Spanners

Previous research and meta-analyses suggest that the influence of organizational variables on boundary role stress processes is weak and marginal. Using the emerging work in organizational practices and configurations, the authors reexamine this relationship by addressing three critical gaps: (1) conceptualizing organizational environment as a multidimensional practices construct, (2) operationalizing the organizational environment as configurations or combinations of practices dimensions, and (3) testing for direct and moderating hypotheses. The results reveal that organizational practices matter significantly in boundary role stress processes. The findings show that procedural environments are dysfunctional because they engender higher levels of role stressors, reduce performance, and negatively affect the psychological well-being of boundary spanners. In contrast, the achievement and affective-oriented environments involve distinct trade-offs, because none is clearly superior. The authors discuss the theoretical implications for further research and provide recommendations for managerial practice.
