Document similarity computation by combining multiple representation models

Evaluating semantic similarity of text document pairs is an active research topic. Various models of document representation have been proposed. Each kind of representation model concentrates on a different kind of information from other kind of models. However, it is difficult for a single model to perform well in all scenarios because of the variety of textual documents. Leveraging these models to complement each other is possible to improve the performance. In this paper, we first make an analysis on the relations among document semantic similarity, human ratings and model performance. Based on the observations, we propose a rational solution of selecting different representation models and fusing the results of these models to compute document similarity for a given document collection. We leverage the performance and relations of different models to select proper models. Our fusion approach proposes a regression function with both nonlinear and linear factors and dynamic weights based on the similarities by various models. We report the effectiveness of our work based on a rated news document collection. The particular version of our general approach for this collection can integrate the information from both brief entity knowledge and detailed word content.
Reachability analysis of the RIOL robot

The paper presents the reachability analysis for the RIOL robot prototype for power line inspection. The robot is a 5-dof articulated multibody with three claws able to move with statically stable gaits. The claws are assumed to grasp the line with some compliance and hence the reachable positions by each the claws are those that compensate for torques induced by gravity.
EZ.WordNet: Principles for Automatic Generation of a Coarse Grained WordNet

In this paper, we propose several principles that enable the automatic transformation of WordNet into a coarser grained dictionary, without affecting its existing semantic relations. We derive a new version of WordNet leading to a reduction of 26% in the average polysemy of words, while introducing a small error rate of 2.1%, as measured on a sense tagged corpus.
How Long Should the Elderly Take Antidepressants?

Of 219 elderly patients with a major depressive disorder (meeting RDC), 69 recovered sufficiently and consented to enter a two-year double-blind placebo-controlled trial of dothiepin. Survival analysis revealed that dothiepin reduced the relative risk of relapse by two and a half times. Past but not current serious physical illness was also associated with a favourable outcome, whereas a prolonged index depressive illness trebled the relative risk of relapse. In the light of previous research on prognosis it is suggested that elderly persons who recover from a major depressive illness should continue with antidepressant medication for at least two years, if not indefinitely.
Study and Development of Novel Feature Selection Framework for Heart Disease Prediction

Heart disease prediction is designed to support clinicians in their diagnosis. We proposed a method for classifying the heart disease data. The patient's record is predicted to find if they have symptoms of heart disease through Data mining. It is essential to find the best fit classification algorithm that has greater accuracy on classification in the case of heart disease prediction. Since the data is huge attribute selection method used for reducing the dataset. Then the reduced data is given to the classification . In the Investigation, the hybrid attribute selection method combining CFS and Filter Subset Evaluation gives better accuracy for classification. We also propose a new feature selection method algorithm which is the hybrid method combining CFS and Bayes Theorem. The proposed algorithm provides better accuracy compared to the traditional algorithm and the hybrid Algorithm CFS+FilterSubsetEval.
ACPM: An associative connectivity prediction model for AANET

Aeronautical ad hoc networks (AANETs) can have a hybrid topology of intermittently connected clusters and mesh network. The hybrid network topology compounded with highly dynamic nature of AANET leads to variable connectivity in the network. The connectivity in the network for direct air-to-air communication between aircrafts is primarily a function of velocity of air vehicles, position of air vehicles, direction of flight, range of communication and congestion. In this paper, we present a connectivity prediction model for the AANET. The proposed model does a space time analysis of connectivity in the regions of AANET. The model can identify areas of low connectivity in a region by grading connectivity in the AANET. The connectivity prediction complements the change in state of an aircraft as it joins the AANET in a cluster or mesh. The model directs idle or migrating members of the network to the higher regions of connectivity. Connectivity gradation reduces network setup time in the events of network disruptions, strengthening the network's self-healing capability. FCM clustering is used for translating 3D topology of the network in conjunction with network traffic to multiple domains, that represent an aircraft.
GeoCoastPilot: A better way of organizing and displaying information in support of port familiarization

GeoCoastPilot is a research software application built to explore techniques for simplifying access to the navigation information a mariner needs prior to entering or leaving a port. GeoCoastPilot is intended to demonstrate what is possible with current technology and to facilitate technology transfer. We started with the question, "What might a digital application based on the NOAA Coast Pilot look like if other marine data sources were combined with it? " Along these lines, GeoCoastPilot introduces two new capabilities to existing marine information products: multiramas and microlinks. These capabilities are intended to help the user develop a more complete and integrated mental model of a port before encountering it for the first time. Operational benefits of GeoCoastPilot include: • decreased time in searching for relevant information; • fewer errors in interpreting the information; and • increased awareness of important navigation aids, hazards, and regulations. In order for commercial software applications to more easily adopt multiramas and microlinking, we advocate two paradigms for data collection and management. First, pertinent marine information sources should be tagged with consistent feature-level metadata. Second, simple mappings of object and attribute names between different information sources should be published and maintained without necessarily being tied to the requirements of any one information source.
Resilience Among Students at the Basic Enlisted Submarine School

Abstract : This study assesses resilience among Sailors at Basic Enlisted Submarine School (BESS), analyzing the effects of positive framing and how changes in resilience affect subjective well-being and perceived stress. An appreciative inquiry-based intervention was administered at two intervals to measure changes according to various scales (e.g., positive framing, perceived-stress scale, resilience, and subjective well-being). Surveys of BESS Sailors were collected at four intervals to examine relationships, trends, and measure changes in scales and self-reported resilience. The Hayes Macro in the Statistical Package for the Social Sciences (SSPS) was used to uncover factors relevant to mediation analysis. Findings suggest that the encouragement of social resilience helps buffer against stress and explains subjective well-being. Improvement of Sailor resilience may improve fleet readiness, productivity, retention, and morale. It is recommended that this study be expanded in scope from BESS to the entire submarine fleet to target and reduce unplanned attrition in the submarine community.
Salicortin-Derivatives from Salix pseudo-lasiogyne Twigs Inhibit Adipogenesis in 3T3-L1 Cells via Modulation of C/EBPα and SREBP1c Dependent Pathway

Obesity is reported to be associated with excessive growth of adipocyte mass tissue as a result of increases in the number and size of adipocytes differentiated from preadipocytes. To search for anti-adipogenic phytochemicals, we screened for inhibitory activities of various plant sources on adipocyte differentiation in 3T3-L1 preadipocytes. Among the sources, a methanolic extract of Salix pseudo-lasiogyne twigs (Salicaceae) reduced lipid accumulation in a concentration-dependent manner. During our search for anti-adipogenic constituents from S. pseudo-lasiogyne, five salicortin derivatives isolated from an EtOAc fraction of this plant and bearing 1-hydroxy-6-oxo-2-cyclohexene-carboxylate moieties, namely 2′,6′-O-acetylsalicortin (1), 2′-O-acetylsalicortin (2), 3′-O-acetylsalicortin (3), 6′-O-acetylsalicortin (4), and salicortin (5), were found to significantly inhibit adipocyte differentiation in 3T3-L1 cells. In particular, 2′,6′-O-acetylsalicortin (1) had the most potent inhibitory activity on adipocyte differentiation, with an IC50 value of 11.6 μM, and it significantly down-regulated the expressions of CCAAT/enhancer binding protein α (C/EBPα) and sterol regulatory element binding protein 1 (SREBP1c). Furthermore, 2′,6′-O-acetylsalicortin (1) suppressed mRNA expression levels of C/EBPβ during the early stage of adipocyte differentiation and stearoyl coenzyme A desaturase 1 (SCD-1), acetyl-CoA carboxylase (ACC), and fatty acid synthase (FAS) expression, target genes of SREBP1c. In the present study, we demonstrate that the anti-adipogenesis mechanism of 2′,6′-O-acetylsalicortin (1) may be mediated via down-regulation of C/EBPα and SREBP1c dependent pathways. Through their anti-adipogenic activity, salicortin derivatives may be potential novel therapeutic agents against obesity.
A new approach for visualizing UML class diagrams

UML diagrams have become increasingly important in the engineering and reengineering processes for software systems. Of particular interest are UML class diagrams whose purpose is to display class hierarchies (generalizations), associations, aggregations, and compositions in one picture. The combination of hierarchical and non-hierarchical relations poses a special challenge to a graph layout tool. Existing layout tools treat hierarchical and non-hierarchical relations either alike or as separate tasks in a two-phase process as in, e.g., [Seemann 1997]. We suggest a new approach for visualizing UML class diagrams leading to a balanced mixture of the following aesthetic criteria: Crossing minimization, bend minimization, uniform direction within each class hierarchy, no nesting of one class hierarchy within another, orthogonal layout, merging of multiple inheritance edges, and good edge labelling. We have realized our approach within the graph drawing library GoVisual. Experiments show the superiority to state-of-the-art and industrial standard layouts.
DEVELOPMENT OF A SPEECH RECOGNIZER FOR THE DUTCH LANGUAGE

This paper describes the development of a large vocabulary speaker independent speech recognizer for the Dutch language. The recognizer was build using Hidden Markov Toolkit and the Polyphone database of recorded Dutch speech. A number of systems have been build ranging from a simple monophone recognizer to a sophisticated system that uses backed-off triphones. The system has been tested using audio from different acoustic environments to test its robustness. The design and the test results will be presented.
Cost utility analysis of sildenafil compared with papaverine-phentolamine injections

Abstract Objective: To compare the cost effectiveness of sildenafil and papaverine-phentolamine injections for treating erectile dysfunction. Design: Cost utility analysis comparing treatment with sildenafil (allowing a switch to injection therapy)and treatment with papaverine-phentolamine (no switch allowed). Costs and effects were estimated from the societal perspective. Using time trade-off, a sample of the general public (n=169) valued health states relating to erectile dysfunction. These values were used to estimated health related quality of life by converting the clinical outcomes of a trial into quality adjusted life years (QALYs). Participants: 169 residents of Rotterdam. Main outcome measures: Cost per quality adjusted life year. Results: Participants thought that erectile dysfunction limits quality of life considerably: the mean utility gain attributable to sildenafil is 0.11. Overall, treatment with sildenafil gained more QALYs, but the total costs were higher. The incremental cost effectiveness ratiofor the introduction of sildenafil was £3639 in the first year and fell in following years. Doubling the frequency of use of sildenafil almost doubled the cost per additional QALY. Conclusions: Treatment with sildenafil is cost effective. When considering fundingsildenafil, healthcare systems should take into account that the frequency of use affects cost effectiveness.
Simplicity in RNA Secondary Structure Alignment: Towards biologically plausible alignments

Ribonucleic acid (RNA) molecules contain the genetic information that regulates the functions of organisms. Given two different molecules, a preserved function corresponds to a preserved secondary RNA structure. Hence, RNA secondary-structure comparison is essential in predicting the functions of a newly discovered molecule. In this paper, we discuss our SPRC method for RNA structure comparison. In this work, we developed, a novel tree representation of RNA that reflects both its primary and secondary structure and a tree-alignment algorithm, which, given the tree representations of two RNA molecules, produces a sequence of mutations that could transform one RNA molecule to the other. Our SPRC algorithm extends the Zhang-Shasha tree-edit distance calculation algorithm in two ways: first, in addition to the distance, it reports all editing sequences with the same minimum edit cost, and second, it uses a biologically-inspired affine cost function. Furthermore, the SPRC method proposes set of heuristics designed to filter the produced solution set to recommend the simplest editing sequence, as corresponding to the most biologically correct alignment. Experiments on three 5S rRNA families: archaea, eubacteria, and eukaryota, show that SPRC is very effective in producing biologically meaningful RNA secondary structure alignments
Risk and Return in Fixed Income Arbitrage: Nickels in Front of a Steamroller?

We conduct an analysis of the risk and return characteristics of a number of widely used fixed income arbitrage strategies. We find that the strategies requiring more “intellectual capital” to implement tend to produce significant alphas after controlling for bond and equity market risk factors. We show that the risk-adjusted excess returns from these strategies are related to capital flows into fixed income arbitrage hedge funds. In contrast with other hedge fund strategies, we find that many of the fixed income arbitrage strategies produce positively skewed returns. These results suggest that there may be more economic substance to fixed income arbitrage than simply “picking up nickels in front of a steamroller. ”
Sex-dependent differences in the regulation of myocardial protein synthesis following long-term ethanol consumption.

Chronic heavy alcohol consumption alters cardiac structure and function. Controversies remain as to whether hearts from females respond to the chronic ethanol intake in a manner analogous to males. In particular, sex differences in the myocardial response to chronic alcohol consumption remain unresolved at the molecular level. The purpose of the present set of experiments was to determine whether alterations in cardiac structure and protein metabolism show sexual dimorphism following chronic alcohol consumption for 26 wk. In control animals, hearts from female rats showed lowered heart weights and had thinner ventricular walls compared with males. The smaller heart size was associated with a lower protein content that occurred in part from a reduced rate of protein synthesis. Chronic alcohol consumption in males, but not in females, caused a thinning of the ventricular wall and intraventricular septum, as assessed by echocardiography, correlating with the loss of heart mass. The alterations in cardiac size occurred, in part, through a lowering of the protein content secondary to a diminished rate of protein synthesis. The decreased rate of protein synthesis appeared related to a reduced assembly of active eukaryotic initiation factor (eIF)4G.eIF4E complex secondary to both a diminished phosphorylation of eIF4G and increased formation of inactive 4Ebinding protein (4EBP1). eIF4E complex. The latter effects occurred as a result of decreased phosphorylation of 4EBP1. None of these ethanol-induced alterations in hearts from males were observed in hearts from females. These data suggest that chronic alcohol-induced impairments in myocardial protein synthesis results, in part, from marked decreases in eIF4E.eIF4G complex formation in males. The failure of female rats consuming ethanol to show structural changes appears related to the inability of ethanol to affect the regulation protein synthesis to the same extent as their male counterparts.
Integrity and function of gestures in aphasia

ABSTRACT Background: Gestures can provide an excellent natural alternative to verbal communication in people with aphasia (PWA). However, despite numerous studies focusing on gesture production in aphasia, it is still a matter of debate whether the gesture system remains intact after language impairment and how PWA use gestures to improve communication. A likely source for the contradicting results is that many studies were conducted on individual cases or in heterogeneous groups of individuals with additional cognitive deficits such as conceptual impairment and comorbid conditions such as limb apraxia. Aims: The goal of the current study was to evaluate the integrity and function of gestures in PWA in light of cognitive theories of language–gesture relationship. Since all such theories presuppose the integrity of the conceptual system, and the absence of comorbid conditions that selectively impair gesturing (i.e., limb apraxia), our sample was selected to fulfill these assumptions. Methods & Procedures: We examined gesture production in eight PWA with preserved auditory comprehension, no comorbidities, and various degrees of expressive deficit, as well as 11 age- and education-matched controls, while they described events in 20 normed video clips. Both speech and gesture data were coded for quantitative measures of informativeness, and gestures were grouped into several functional categories (matching, complementary, compensatory, social cueing, and facilitating lexical retrieval) based on correspondence to the accompanying speech. Using rigorous group analyses, individual-case analyses, and analyses of individual differences, we provide converging evidence for the integrity and type of function(s) served by gesturing in PWA. Outcomes & Results: Our results indicate that the gesture system can remain functional even when language production is severely impaired. Our PWA heavily relied on iconic gestures to compensate for their language impairment, and the degree of such compensation was correlated with the extent of language impairment. In addition, we found evidence that producing iconic gestures was related to higher success rates in resolving lexical retrieval difficulties. Conclusions: When comprehension and comorbidities are controlled for, impairment of language and gesture systems is dissociable. In PWA with good comprehension, gesturing can provide an excellent means to both compensate for the impaired language and act as a retrieval cue. Implications for cognitive theories of language–gesture relationship and therapy are discussed.
The Clinical and Radiographic Importance of Distinguishing Partial from Near-Complete Reperfusion Following Intra-Arterial Stroke Therapy

BACKGROUND AND PURPOSE: Reperfusion following intra-arterial stroke therapy is associated with improved clinical outcomes. However, the degree of reperfusion needed to achieve successful outcomes is unknown. The purpose of this analysis was to determine whether the degree of reperfusion has an impact on final infarct volumes and clinical outcomes. MATERIALS AND METHODS: A retrospective analysis identified 88 consecutive patients who underwent intra-arterial therapy for acute anterior circulation stroke. Reperfusion was graded by using the TICI scale into none (TICI 0 or 1), partial (TICI 2a), or near-complete (TICI 2b/3). Baseline characteristics were compared. For each of these groups, we compared discharge disposition and final infarct volumes. RESULTS: Near-complete, partial, and no reperfusion occurred in 44.3%, 26.1%, and 29.6% of patients, respectively. Baseline characteristics were similar across all 3 groups. The median NIHSS score was 15. Significant differences in discharge disposition were seen, with 41.0% of the TICI 2b/3 group discharged home versus 17.4% of TICI 2a and 7.7% of TICI 0/1. In-hospital mortality was 12.8% for TICI 2b/3 compared with 39.1% for TICI 2a and 34.6% for TICI 0/1. Patients with near-complete reperfusion were significantly more likely to have infarct volumes ≤70 mL (OR = 12.1; 95% CI, 2.7–54.2), compared with patients with partial reperfusion (OR = 2.2; 95% CI, 0.5–9.6). CONCLUSIONS: Significant differences exist in outcomes and infarct volumes between partial (TICI 2a) and near-complete (TICI 2b/3) reperfusion following intra-arterial stroke therapy. Further trials should separately report these groups to facilitate comparison among treatment paradigms.
On the Complexity of the Regenerator Placement Problem in Optical Networks

Placement of regenerators in optical networks has attracted the attention of recent research works in optical networks. In this problem, we are given a network with an underlying topology of a graph G and with a set of requests that correspond to paths in G. There is a need to put a regenerator every certain distance, because of a decrease in the power of the signal. In this paper, we investigate the problem of minimizing the number of locations to place the regenerators. We present analytical results regarding the complexity of this problem, in four cases, depending on whether or not there is a bound on the number of regenerators at each node, and depending on whether or not the routing is given or only the requests are given (and part of the solution is also to determine the actual routing). These results include polynomial time algorithms, NP-completeness results, approximation algorithms, and inapproximability results.
