Web video categorization based on Wikipedia categories and content-duplicated open resources

This paper presents a novel approach for web video categorization by leveraging Wikipedia categories (WikiCs) and open resources describing the same content as the video, i.e., content-duplicated open resources (CDORs). Note that current approaches only collect CDORs within one or a few media forms and ignore CDORs of other forms. We explore all these resources by utilizing WikiCs and commercial search engines. Given a web video, its discriminative Wikipedia concepts are first identified and classified. Then a textual query is constructed and from which CDORs are collected. Based on these CDORs, we propose to categorize web videos in the space spanned by WikiCs rather than that spanned by raw tags. Experimental results demonstrate the effectiveness of both the proposed CDOR collection method and the WikiC voting categorization algorithm. In addition, the categorization model built based on both WikiCs and CDORs achieves better performance compared with the models built based on only one of them as well as state-of-the-art approach.
CoCoa: a software tool for estimating the coefficient of coancestry from multilocus genotype data

MOTIVATION Phenotypic data collected in breeding programs and marker-trait association studies are often analyzed by means of linear mixed models. In these models, the covariance between the genetic background effects of all genotypes under study is modeled by means of pairwise coefficients of coancestry. Several marker-based coancestry estimation procedures allow to estimate this covariance matrix, but generally introduce a certain amount of bias when the examined genotypes are part of a breeding program. CoCoa implements the most commonly used marker-based coancestry estimation procedures and as such, allows to select the best fitting covariance structure for the phenotypic data at hand. This better model fit translates into an increased power and improved type I error control in association studies and an improved accuracy in phenotypic prediction studies. The presented software package also provides an implementation of the new Weighted Alikeness in State (WAIS) estimator for use in hybrid breeding programs. Besides several matrix manipulation tools, CoCoa implements two different bending heuristics, in case the inverse of an ill-conditioned coancestry matrix estimate is needed. AVAILABILITY AND IMPLEMENTATION The software package CoCoa is freely available at http://webs.hogent. be/cocoa. Source code, manual, binaries for 32 and 64-bit Linux systems and an installer for Microsoft Windows are provided. The core components of CoCoa are written in C++, while the graphical user interface is written in Java.
Low Raltegravir Concentration in Cerebrospinal Fluid in Patients With ABCG2 Genetic Variants

Abstract:Adenosine triphosphate–binding cassette transporter G2 (ABCG2) is expressed on the cerebrospinal fluid (CSF) side of choroid plexus epithelial cells, which form the blood–CSF barrier. Raltegravir was recently identified as a substrate of ABCG2. In the present study, we analyzed the relationship between single-nucleotide polymorphisms of ABCB1 and ABCG2 genes and raltegravir concentrations in 31 plasma and 14 CSF samples of HIV-infected patients treated with raltegravir-containing regimens. The mean CSF raltegravir concentration was significantly lower in CA (25.5 ng/mL) and AA (<10 ng/mL) genotypes at position 421 in ABCG2 gene compared with CC (103.6 ng/mL) genotype holders (P = 0.016).
Formal validation of pattern matching code

When addressing the formal validation of generated software, two main alternatives consist either to prove the correctness of compilers or to directly validate the generated code. Here, we focus on directly proving the correctness of compiled code issued from powerful pattern matching constructions typical of ML like languages or rewrite based languages such as ELAN, Maude or Tom. In this context, our first contribution is to define a general framework for anchoring algebraic pattern-matching capabilities in existing languages like C, Java or ML. Then, using a just enough powerful intermediate language, we formalize the behavior of compiled code and define the correctness of compiled code with respect to pattern-matching behavior. This allows us to prove the equivalence of compiled code correctness with a generic first-order proposition whose proof could be achieved via a proof assistant or an automated theorem prover. We then extend these results to the multi-match situation characteristic of the ML like languages. The whole approach has been implemented on top of the Tom compiler and used to validate the syntactic matching code of the Tom compiler itself.
Morphology Control by the Centrifugation Method for Bulk Heterojunction Solar Cells

A number of studies have been reported thin-film bulk heterojunction solar cells using p-type semiconducting materials as electron donors and n-type semiconducting materials as electron acceptors. Moreover, some studies have reported that controlling the morphology of the photoactive layer is important. In this study, we report a novel method for film formation utilizing centrifugation to control the morphology of the photoactive layer in thin-film solar cells. By employing this method, we observed high performance. Furthermore, the photoactive layer formed by the centrifugation method resulted in suitable phase-separated structures for charge separation and charge transfer, which were similar to a mutual penetration structure. We also fabricated thin-film bulk heterojunction solar cells using this method and obtained a performance that was 2.2 times greater than that obtained by the conventional spin-coating method using a p-type semiconducting polymer and Ti(IV) isopropoxide as the electron donor and electron acceptor, respectively.
Transmit Antenna Selection for Downlink Transmission in a Massively Distributed Antenna System Using Convex Optimization

The use of multiple antennas in a spatial multiplexing multiple-input multiple-output (SM-MIMO) system can increase the capacity linearly with the number of antennas, M. However, the radio-frequency (RF) chain associated with each antenna increases the system hardware cost considerably. Antenna selection is a signal processing technique that helps to reduce the system complexity and cost of the RF front-end. This paper describes the novel concept of transmit antenna selection method for the massively distributed antenna system, which is conceived as a technique to increase the data-rate beyond the Long Term Evolution (LTE) and LTE Advanced (LTEA) technologies. In this work, convex optimization is used to determine the optimum antennas for the massively distributed MIMO, to achieve the best compromise between the achievable capacity and system complexity. Specifically, the interior-point algorithm from optimization theory is utilized. For the case of an extremely large antenna array, we observe from the simulations that antenna selection is dependent only upon the large scale fading (LSF). So complexity of the antenna selection algorithm reduces to O(M) if the bucket sorting algorithm is employed. Simulation results confirm that our proposed method works well in a massively distributed antenna system, and its performance is close to the optimal antenna selection algorithm.
Gravity-driven slug motion in capillary tubes

The velocity of a liquid slug falling in a capillary tube is lower than predicted for Poiseuille flow due to presence of menisci, whose shapes are determined by the complex interplay of capillary, viscous, and gravitational forces. Due to the presence of menisci, a capillary pressure proportional to surface curvature acts on the slug and streamlines are bent close to the interface, resulting in enhanced viscous dissipation at the wedges. To determine the origin of drag-force increase relative to Poiseuille flow, we compute the force resultant acting on the slug by integrating Navier–Stokes equations over the liquid volume. Invoking relationships from differential geometry we demonstrate that the additional drag is due to viscous forces only and that no capillary drag of hydrodynamic origin exists (i.e., due to hydrodynamic deformation of the interface). Requiring that the force resultant is zero, we derive scaling laws for the steady velocity in the limit of small capillary numbers by estimating the leadi.

Clinical significance of dynamic pulmonary vascular resistance in two populations at risk of pulmonary arterial hypertension.

AIMS Patients at risk of pulmonary arterial hypertension (PAH) may present with abnormal dynamic pulmonary vascular resistance (PVR) during exercise. However, its clinical significance remains unclear. The present study aimed at analysing the meaning of dynamic PVR in two populations at risk of PAH: secundum atrial septal defect (ASD) and systemic sclerosis (SSc). METHODS AND RESULTS Adult patients with corrected ASD were consecutively selected from the database of Pediatric and Congenital Heart Disease of the University Hospitals Leuven. Patients with SSc were consecutively selected from the rheumatology database of the University Hospital Liège. At inclusion, all underwent a rest and bicycle stress echocardiography to obtain baseline right heart characteristics and dynamic PVR. Routine follow-up echocardiography was performed. Twenty-eight patients with corrected ASD (mean age 41 ± 17 years, 79% female) were followed for a median time of 3.7 [inter-quartile range (IQR) 2.9-4.1] years. No patient developed PAH. Dynamic PVR was significantly associated with right atrial dilatation at latest follow-up (Spearman's ρ 0.51, P = 0.013). Forty-five SSc patients (mean age 54 ± 13 years, 76% female) were followed for a median time of 2.4 (IQR 0.8-2.9) years. Thirteen patients (30%) developed PAH. Dynamic PVR was the only independent predictor of PAH (hazards ratio 1.22, 95% confidence interval 1.01-1.47). No significant right heart morphometric changes occurred. CONCLUSION Dynamic PVR predicted PAH development in patients with SSc, whereas dynamic PVR was associated with right heart morphometric changes after ASD closure. The predictive role of dynamic PVR might depend on the underlying disease type. Larger studies are needed to confirm this hypothesis.
Improved vascular organization enhances functional integration of engineered skeletal muscle grafts

Severe traumatic events such as burns, and cancer therapy, often involve a significant loss of tissue, requiring surgical reconstruction by means of autologous muscle flaps. The scant availability of quality vascularized flaps and donor site morbidity often limit their use. Engineered vascularized grafts provide an alternative for this need. This work describes a first-time analysis, of the degree of in vitro vascularization and tissue organization, required to enhance the pace and efficacy of vascularized muscle graft integration in vivo. While one-day in vitro was sufficient for graft integration, a three-week culturing period, yielding semiorganized vessel structures and muscle fibers, significantly improved grafting efficacy. Implanted vessel networks were gradually replaced by host vessels, coupled with enhanced perfusion and capillary density. Upregulation of key graft angiogenic factors suggest its active role in promoting the angiogenic response. Transition from satellite cells to mature fibers was indicated by increased gene expression, increased capillary to fiber ratio, and similar morphology to normal muscle. We suggest a “relay” approach in which extended in vitro incubation, enabling the formation of a more structured vascular bed, allows for graft-host angiogenic collaboration that promotes anastomosis and vascular integration. The enhanced angiogenic response supports enhanced muscle regeneration, maturation, and integration.

I thank Jim for allowing me to work on his baby. I understand what a statement of trust that is and hope to continue in his impressive tradition. I want to dedicate this edition to all the hardworking, under-appreciated TAFE teachers out there, especially those I have worked with and who, in the tradition of tradespeople, have supported this and many other efforts of their fellow teachers. Last but by no means least, I thank my family and especially my wife Carole, without whose support this book would not have happened.
The impact of stretching on sports injury risk: a systematic review of the literature.

PURPOSE We conducted a systematic review to assess the evidence for the effectiveness of stretching as a tool to prevent injuries in sports and to make recommendations for research and prevention. METHODS Without language limitations, we searched electronic data bases, including MEDLINE (1966-2002), Current Contents (1997-2002), Biomedical Collection (1993-1999), the Cochrane Library, and SPORTDiscus, and then identified citations from papers retrieved and contacted experts in the field. Meta-analysis was limited to randomized trials or cohort studies for interventions that included stretching. Studies were excluded that lacked controls, in which stretching could not be assessed independently, or where studies did not include subjects in sporting or fitness activities. All articles were screened initially by one author. Six of 361 identified articles compared stretching with other methods to prevent injury. Data were abstracted by one author and then reviewed independently by three others. Data quality was assessed independently by three authors using a previously standardized instrument, and reviewers met to reconcile substantive differences in interpretation. We calculated weighted pooled odds ratios based on an intention-to-treat analysis as well as subgroup analyses by quality score and study design. RESULTS Stretching was not significantly associated with a reduction in total injuries (OR = 0.93, CI 0.78-1.11) and similar findings were seen in the subgroup analyses. CONCLUSION There is not sufficient evidence to endorse or discontinue routine stretching before or after exercise to prevent injury among competitive or recreational athletes. Further research, especially well-conducted randomized controlled trials, is urgently needed to determine the proper role of stretching in sports.
Polymorphous Ventricular Tachycardia Associated With Acute Myocardial Infarction

BackgroundDuring a 2.9-year period, 11 patients developed polymorphous ventricular tachycardia 1–13 days after acute anterior (seven patients) or inferior (four patients) myocardial infarction. None of the 11 patients had sinus bradycardia (mean heart rate, 90 ± 23 beats/min), but three had a sinus pause immediately before the onset of polymorphous ventricular tachycardia. In all 11 patients, the QT interval and corrected QT interval (QTj) were normal or minimally prolonged (QT, 385 + 34 msec; QT, 442 ± 40 msec). None had significant hypokalemia (mean serum potassium concentration, 43 ± 0.5 meq/l) or a grossly abnormal serum magnesium or calcium concentration (2.1 ± 0.4 and 8.9 ± 0.7 mg/dl, respectively). Methods and ResultsImmediately before the onset of polymorphous ventricular tachycardia, symptoms and/or electrocardiographic changes consistent with recurrent myocardial ischemia occurred in nine of 11 patients. One patient died before drug therapy could be initiated. Lidocaine was used in 10 patients and proved to be effective in only one. Intravenous procainamide was used in six patients: one improved, and five had recurrence of polymorphous ventricular tachycardia. Bretylium was used in five patients and was ineffective in all cases. Overdrive pacing was used in four patients and failed to suppress recurrent arrhythmias in all cases. Four patients with persistent polymorphous ventricular tachycardia unresponsive to lidocaine, procainamide, or bretylium responded to intravenous amiodarone. One patient with polymorphous ventricular tachycardia that was consistently preceded by ST segment elevation responded to intravenous nitroglycerin. Two patients with persistent polymorphous ventricular tachycardia and obvious recurrent ischemia unresponsive to pharmacological intervention responded to emergency coronary revascularization. A third patient who experienced recurrent angina and polymorphous tachycardia was initially stabilized with pharmacological therapy but subsequently underwent elective revascularization and has remained stable without antiarrhythmic therapy. ConclusionsPost-myocardial infarction polymorphous ventricular tachycardia is not consistently related to an abnormally long QT interval, sinus bradycardia, preceding sinus pauses, or electrolyte abnormalities. This arrhythmia has a variable response to class I antiarrhythmics but may be suppressed by intravenous amiodarone therapy. It is often associated with signs or symptoms of recurrent myocardial ischemia. Furthermore, coronary revascularization appears to be effective in preventing the recurrence of polymorphous ventricular tachycardia when associated with recurrent postinfarction angina.
GLML: Annotating Argument Selection and Coercion

In this paper we introduce a methodology for annotating compositional operations in natural language text, and describe a mark-up language, GLML, based on Generative Lexicon, for identifying such relations. While most annotation systems capture surface relationships, GLML captures the "compositional history" of the argument selection relative to the predicate. We provide a brief overview of GL before moving on to our proposed methodology for annotating with GLML. There are three main tasks described in the paper: (i) Compositional mechanisms of argument selection; (ii) Qualia in modification constructions; (iii) Type selection in modification of dot objects. We explain what each task includes and provide a description of the annotation interface. We also include the XML format for GLML including examples of annotated sentences.
Statistical Machine Translation based on LDA

Current Statistical Machine Translation (SMT) systems translate one sentence at a time, ignoring any document level information. Consequently, translation models are learned only at sentence level and document contexts are generally overlooked. In this paper, we try to introduce document topic to help SMT system to produce target sentences. First, the parallel training corpus with underlying document boundary is segmented into multiple documents, and then we use a monolingual LDA model to determine which topics these documents belong to. Next, the background phrase table is enhanced with the probability distribution of a document over topics. Evaluation shows that our proposed approach significantly improves the BLEU score on Chinese-to-English machine translation.
Mining Techniques in Network Security to Enhance Intrusion Detection Systems

In intrusion detection systems, classifiers still suffer from several drawbacks such as data dimensionality and dominance, different network feature types, and data impact on the classification. In this paper two significant enhancements are presented to solve these drawbacks. The first enhancement is an improved feature selection using sequential backward search and information gain. This, in turn, extracts valuable features that enhance positively the detection rate and reduce the false positive rate. The second enhancement is transferring nominal network features to numeric ones by exploiting the discrete random variable and the probability mass function to solve the problem of different feature types, the problem of data dominance, and data impact on the classification. The latter is combined to known normalization methods to achieve a significant hybrid normalization approach. Finally, an intensive and comparative study approves the efficiency of these enhancements and shows better performance comparing to other proposed methods.
Relationship of angiographically defined coronary artery disease to serum lipoproteins and apolipoproteins in young survivors of myocardial infarction.

The relationship of serum lipoprotein and apolipoprotein concentrations to angiographically determined coronary artery disease was investigated in 105 consecutive male survivors of myocardial infarction under the age of 45. Concentrations and composition of lipoproteins, lipid indexes, and nonlipid risk factors (tobacco consumption, hypertension, reduced glucose tolerance, and obesity) were related to a recently developed scoring system for semiquantitative estimation of diffuse coronary atheromatosis, as well as to the number and severity of significant coronary artery stenoses. The concentrations of cholesterol in very low-density lipoprotein (VLDL), low-density lipoprotein (LDL), and high-density lipoprotein (HDL), in combination with serum triglyceride or VLDL triglyceride level, comprised the best set of independent discriminatory lipid variables between patients and control subjects. In the patients, LDL cholesterol and apolipoprotein B levels showed strong relationships to the extent and severity of coronary atheromatosis but not to the number and severity of distinct coronary stenoses. HDL2 cholesterol concentration correlated inversely with the coronary atheromatosis score, whereas other variables reflecting HDL concentration and composition or VLDL lipids were not independently related to any of the coronary scores. The LDL triglyceride level, an index of intermediate-density lipoprotein (IDL) accumulation, was significantly correlated to the coronary atheromatosis score in univariate analysis. Nonlipid risk factors were correlated neither to coronary atheromatosis nor to severity of stenoses. Stepwise multiple regression analyses of data adjusted for age, cumulative tobacco consumption, and weight indicated that 18% of the variation in the coronary atheromatosis score could be accounted for by levels of apolipoprotein B. Addition of other lipoprotein variables or the nonlipid variables hypertension and glucose tolerance did not significantly increase the value of R2. When ratios of lipoprotein lipids and apolipoproteins were included in the regression model, the highest multiple correlation coefficient was obtained with the LDL/HDL cholesterol ratio alone (R2 = .22). The present data demonstrate the importance of elevated LDL cholesterol and apolipoprotein B concentrations for the development of coronary atheromatosis in young male survivors of myocardial infarction. The lack of correlations between the levels of lipoprotein lipids and serum apolipoproteins and the severity of coronary stenoses suggests that mechanisms other than disturbances of lipoprotein metabolism may be involved in the progression of more advanced coronary lesions.
