Curve-based stereo: figural continuity and curvature

An edge-based trinocular stereovision algorithm is presented. The primitives it works on are cubic B-spline approximations of the 2-D edges. This allows one to deal conveniently with curvature and to extend to some nonpolyhedral scenes to previous stereo algorithms. To build a matching primitive, the principle of the algorithm is, first, to find a triplet of corresponding points on three splines. This is provided by the bootstrapping part. Second, the algorithm propagates along the three supporting splines to find other matching points. This provides a set of ordered point triplets along these three splines, for which all the matching constraints are verified. This primitive constitutes a trinocular hypothesis. The set of all hypotheses is obtained by propagating from all the point triplets provided by the bootstrapping process. A criterion based on the size of the hypotheses is then used to choose among them a compatible set with respect to the uniqueness constraint. Results of several 3-D reconstructed scenes are shown. <<ETX>>
Validation of a 4‐item Negative Symptom Assessment (NSA‐4): a short, practical clinical tool for the assessment of negative symptoms in schizophrenia

The 16‐item Negative Symptom Assessment (NSA‐16) scale is a validated tool for evaluating negative symptoms of schizophrenia. The psychometric properties and predictive power of a four‐item version (NSA‐4) were compared with the NSA‐16. Baseline data from 561 patients with predominant negative symptoms of schizophrenia who participated in two identically designed clinical trials were evaluated. Ordered logistic regression analysis of ratings using NSA‐4 and NSA‐16 were compared with ratings using several other standard tools to determine predictive validity and construct validity. Internal consistency and test–retest reliability were also analyzed. NSA‐16 and NSA‐4 scores were both predictive of scores on the NSA global rating (odds ratio = 0.83–0.86) and the Clinical Global Impressions–Severity scale (odds ratio = 0.91–0.93). NSA‐16 and NSA‐4 showed high correlation with each other (Pearson r = 0.85), similar high correlation with other measures of negative symptoms (demonstrating convergent validity), and lesser correlations with measures of other forms of psychopathology (demonstrating divergent validity). NSA‐16 and NSA‐4 both showed acceptable internal consistency (Cronbach α, 0.85 and 0.64, respectively) and test–retest reliability (intraclass correlation coefficient, 0.87 and 0.82). This study demonstrates that NSA‐4 offers accuracy comparable to the NSA‐16 in rating negative symptoms in patients with schizophrenia. Copyright © 2011 John Wiley & Sons, Ltd.
Multi motor drive based on a dual purpose DC-DC power conversion system

This paper presents a multi motor drive based on a dual purpose energy conversion system with an energy storage. The proposed structure and control are directly applicable for heating ventilation and air conditioning (HVAC) systems adding an energy storage functionality. Based on the new structure, a dual functional control scheme has been introduced to manage the charging/discharging of the energy storage and to regulate two capacitor voltages, which are inverter input voltages, simultaneously. Two independent permanent magnet (PM) sensorless motor drives, which are connected to the two capacitors, are controlled in real time for HVAC applications. Simulation and experimental results verify the feasibility of the proposed structure and control scheme.
Clock-Skew Test Module for Exploring Reliable Clock-Distribution Under Process and Global Voltage-Temperature Variations

This paper presents a clock-skew test module for exploring reliable clock distribution under process, voltage, and temperature (PVT) variations. The proposed test module enables direct evaluation of the following two important issues: 1) the clock-skew process variations and 2) the robustness against race problems under environmental variations such as voltages and temperatures. The test module was fabricated by using a 90-nm low-power process for system-on-chip (SoC). It contains eight blocks including H-tree blocks and clock tree synthesis (CTS)-tree blocks (i.e., blocks formed by clock-tree synthesis), each of which has 1024 flip-flop (FF) pairs with small hold-time margins. A statistical method has been developed for analyzing the measured hold-time margins of the 1024 FF pairs for 80 chips. The example of the analysis for the measured results is presented, confirming the effectiveness of the proposed test module and analysis method toward reliable design of clock distribution.
Molecular determinants of the inhibition of human Kv1.5 potassium currents by external protons and Zn2+

Using human Kv1.5 channels expressed in HEK293 cells we assessed the ability of H+o to mimic the previously reported action of Zn2+ to inhibit macroscopic hKv1.5 currents, and using site‐directed mutagenesis, we addressed the mechanistic basis for the inhibitory effects of H+o and Zn2+. As with Zn2+, H+o caused a concentration‐dependent, K+o‐sensitive and reversible reduction of the maximum conductance (gmax). With zero, 5 and 140 mm K+o the pKH for this decrease of gmax was 6.8, 6.2 and 6.0, respectively. The concentration dependence of the block relief caused by increasing [K+]o was well fitted by a non‐competitive interaction between H+o and K+o, for which the KD for the K+ binding site was 0.5‐1.0 mm. Additionally, gating current analysis in the non‐conducting mutant hKv1.5 W472F showed that changing from pH 7.4 to pH 5.4 did not affect Qmax and that charge immobilization, presumed to be due to C‐type inactivation, was preserved at pH 5.4. Inhibition of hKv1.5 currents by H+o or Zn2+ was substantially reduced by a mutation either in the channel turret (H463Q) or near the pore mouth (R487V). In light of the requirement for R487, the homologue of Shaker T449, as well as the block‐relieving action of K+o, we propose that H+ or Zn2+ binding to histidine residues in the pore turret stabilizes a channel conformation that is most likely an inactivated state.
Preoperative high-intensity training in frail old patients undergoing pulmonary resection for NSCLC

Abstract Thoracic surgery remains the better therapeutic option for non-small cell lung cancer patients that are diagnosed in early stage disease. Preoperative lung function assessment includes respiratory function tests (RFT) and cardio-pulmonary exercise testing (CPET). Vo2 peak, FEV1 and DLCO as well as recognition of performance status, presence of co-morbidities, frailty indexes, and age predict the potential impact of surgical resection on patient health status and survival risk. In this study we have retrospectively assessed the benefit of a high-intensity preoperative pulmonary rehabilitation program (PRP) in 14 patients with underlying lung function impairment prior to surgery. Amongst these, three patients candidate to surgical resection exhibited severe functional impairment associated with high score of frailty according CHS and SOF index, resulting in a substantial mortality risk. Our observations indicate that PRP appear to reduce the mortality and morbidity risk in frail patients with concurrent lung function impairment undergoing thoracic surgery. PRP produced improvement of VO2 peak degree and pulmonary function resulting in reduced postoperative complications in high-risk patients from our cases. Our results indicate that a preoperative training program may improve postoperative clinical outcomes in fraillung cancer patients with impaired lung function prior to surgical resection.
Application of miniaturized indefinite magnetic metamaterial lens in wireless power transfer

The application of miniaturized indefinite magnetic metamaterial lens (IMML) in wireless power transfer (WPT) are numerically investigated. Vibrations of efficiency can be observed by sweeping the geometrical size or permeability of the IMML. By optimizing the parameters of IMML, the volume of the metamaterial lens can be miniaturized to the extent in which the lens is portable and flexible enough for practical using without obvious sacrifice of efficiency comparing to large-sized planar metamaterial lens. Furthermore, this phenomenon can be viewed as the performance of metamaterial resonator.

Difference of Spatial Frequency Selectivity between Static and Flicker Motion Aftereffects

The strength of motion aftereffect (MAE) was measured with the use of sinusoidal gratings of several spatial frequencies, to examine the spatial frequency selectivity of two types of MAE. With ordinary static grating as a test stimulus, to measure ‘static MAE’, the maximum aftereffect for each adapting spatial frequency was obtained at the testing stimuli of the same spatial frequency, showing spatial frequency selectivity. However, in the case when the sinusoidally flickering grating was used as a test stimulus, to measure ‘flicker MAE’, no spatial frequency selectivity was observed. The two types of MAE were considered to be based on different mechanisms. Static MAE is thought to depend on the spatiotemporal channel mechanism in the early processing stages, whereas flicker MAE might reflect higher-level processes which might occur at the extrastriate regions.
Invasive meningococci with reduced susceptibility to penicillin in Portugal.

Sir, Since the description of the first clinical isolate of Neisseria meningitidis with reduced susceptibility to penicillin (MRSP), similar findings have been reported from a number of countries. At the same time, the frequency of serogroup C meningococci has increased in Europe. Twenty-seven MRSP invasive strains recovered from the collection of the Antibiotic Resistance Unit at the National Institute of Health in Lisbon were analysed. MRSP were defined as strains with a penicillin MIC of 0.12–1 mg/L. MICs of penicillin and of ampicillin (Wyeth Lederle Portugal), cefotaxime (Hoechst Marion Rousel), ceftriaxone (Roche Pharmaceuticals), ciprofloxacin (Bayer Portugal) and rifampicin (Novartis Farma) were determined by an agar dilution method according to NCCLS guidelines. Serogroup determination was carried out by a slide agglutination method with specific antisera (Murex Biotech, Dartford, UK). -Lactamase production was assessed on all isolates by chromogenic cephalosporin assay (Oxoid, Basingstoke, UK). Ampicillin was found to be less active than penicillin against meningococci (Table). None of the isolates produced -lactamase. All meningococci were fully susceptible to cefotaxime, ceftriaxone, ciprofloxacin and rifampicin. Most of the MRSP isolates were from serogroup C (19/27, 70.4%), but 6/27 (22.2%) belonged to serogroup B and 2/27 (7.4%) belonged to serogroup W135. These results suggest that ceftriaxone or cefotaxime should become the antibiotic of choice for treating meningococcal meningitis in the face of the possible development of penicillin resistance. As there appears to be no immediate risk of resistance to rifampicin or ciprofloxacin, these antibiotics should continue to be used for prophylaxis among contacts. In this study we demonstrate a high prevalence of MRSP in serogroup C, which indicates that meningococcal group C conjugate (MCC) vaccine in national prophylaxis programmes could be very useful in countries with such a high prevalence. Immunization with effective vaccines is the best approach for controlling meningococcal disease, and the MCC vaccine has been demonstrated to have an effect on the epidemiological pattern of serogroup C infection. Our data highlight the importance of serotype and resistance surveillance for these pathogens in helping to define health policies. Improvements in the submission of meningococcal isolates to national reference laboratories are crucial for maximizing the efficacy of this surveillance.
The effect of ice ingestion on female athletes performing intermittent exercise in hot conditions

Abstract Studies have reported the benefits of pre-cooling prior to exercise in the heat for male athletes, but at this time no research has investigated female athletes. The aim of the following study was to test the effects of pre-cooling on female repeat sprint performance in hot, humid conditions; namely is ice ingestion effective in reducing core temperature (Tc) and does this reduced Tc lead to improved repeat sprint performance in female athletes? Nine female team sport athletes with mean age (21.0 ± 1.2 y), height (169.8 ± 4.1 cm) and body mass (62.3 ± 5.0 kg) participated in this study. Participants completed 72 min of an intermittent sprint protocol (ISP) consisting of 2 × 36 min halves in hot, humid conditions (33.1 ± 0.1°C, 60.3 ± 1.5% RH) on a cycle ergometer. This was preceded by 30 min of either ice ingestion (ICE) or water consumption (CON) in a randomised order. At the end of the pre-cooling period, Tc significantly decreased following ICE (−0.7 ± 0.3°C) compared to CON (−0.1 ± 0.2°C; p = 0.001). Tc also remained lower in ICE compared to CON during the ISP (p = 0.001). Ratings of perceived thermal sensation were lower in ICE compared to CON (p = 0.032) at the beginning (p = 0.022) and mid-point (p = 0.035) of the second half. No differences in work, mean power, peak power, rating of perceived exertion, heart rate or sweat loss between conditions were recorded (p > 0.05). Ice ingestion significantly reduced female Tc prior to intermittent exercise in the heat and reduced thermal sensation; however, this did not coincide with improved performance.
Mobility Reduces the Number of Secondary Users in Cognitive Radio Networks

In this paper, we study the capacity and delay scaling laws for cognitive radio networks (CRN). The primary network consists of $n$ static, randomly and evenly distributed primary users (PUs), which require high throughput with low delay. The secondary network consists of $m=O(n^{1+\delta})$ randomly and evenly distributed cognitive secondary users (SUs) with $\delta>0$, which move in different area according to the hierarchical i.i. d. mobility model. The secondary network is carefully designed to support the primary network, so that PUs may achieve near-optimal performance in both capacity and delay aspects. Then by utilizing hierarchical cooperation among SUs with different mobility, a new hierarchical relay algorithm is proposed to improve the delay performance extensively. Under optimal condition, this algorithm may provide $\Omega(n^{- \delta'})$ per-node throughput and $O(n^{\delta''})$ average delay for PU with $\delta',\delta''>0$, and significantly improve the performance of SU at the same time.
Social Support Factor Structure in the Elderly

This research examines the factor structure of social support measures using the responses of a sample of 210 elderly. Four measures selected to operationalize socioemotional and instrumental support were administered as part of a structured interview including demographic, health status, and life satisfaction measures. A principal axes factor analysis followed by oblique rotation generated a four factor solution. The derived factors were interpreted as (1) support intensity, (2) social contacts, (3) social resource availability, and (4) telephone contacts.
How Do Institution-Based Trust and Interpersonal Trust Affect Interdepartmental Knowledge Sharing?

There are two typical forms of trust in organisational settings—institution-based trust and interpersonal trust. The role of interpersonal trust in promoting interdepartmental knowledge sharing has been investigated. The effect of institution-based trust, especially the joint effect of institution-based and interpersonal trust, on interdepartmental knowledge sharing has not been adequately described. This article builds a conceptual model to describe the independent and joint effects of these two forms of trust on the satisfaction and success of interdepartmental knowledge sharing. The moderating role of knowledge tacitness is also described in this model, which is tested on 294 collaborative task scenarios between departments within Chinese IT firms. The empirical results essentially support the proposed model and contribute to organisational trust and interdepartmental knowledge-sharing discussions by clarifying the substantial roles of these two forms of trust in the context of interdepartmental collaboration and knowledge sharing.
Use case extractor: XML parser for automated extraction and storage of use - Case diagram

There are many students who can not afford higher education due to any of the reasons. If some teachers who are expert in his/her subject can upload their material on web then the students who cannot afford education from good academic institution can take benefit out of this. For e-learning to be effective students must also be given assignment and test. And their work must be evaluated online. However evaluating large number of students online is very tedious and cumbersome task. Expert teachers are coming forward and uploading their material online so that the large number of students benefit out of it. But when the number of student is very large, nobody is interested or very few teachers are readily available for evaluation. This paper describes the tool named Use Case Extractor developed by us towards achieving our research objective of Automate evaluation of the Use - Case diagram. Use Case Extractor fetches the Use - Case diagram created in StarUML by user and is available in the form of XML file and successfully stores the fetched diagram in the database appropriately to be used further for the automatic evaluation.
Optimization of the boundary conditions and computational parameters for the FDTD solution of the inverse problem of reconstructing permittivity of a dielectric inclusion in a waveguide

Wave propagation in a waveguide of rectangular cross section with perfectly conducting wall containing an inhomogeneous dielectric insert in the form of a parallel-plane diaphragm with an inclusion is simulated numerically. The permittivity of the inclusion is a quantity to be restored from as little information about the scattered field as possible using FDTD numerical solution of Maxwell's equations with nonlocal multimode scattering boundary conditions. The optimal number of higher-order evanescent waves and the size of the computational waveguide domain are found using the series of numerical experiments.
Evidence-Based Psychosocial Treatments for Children and Adolescents With Attention Deficit/Hyperactivity Disorder

The purpose of this research was to update the series of articles on evidence-based treatment for children and adolescents with attention deficit/hyperactivity disorder that have appeared in this journal (Evans, Owens & Bunford, 2014; Pelham & Fabiano, 2008; Pelham, Wheeler, & Chronis, 1998). We completed a systematic review of the literature published between 2012 and 2016 to establish levels of evidence for psychosocial treatments for these youth. We identified articles using criteria established by the Society of Clinical Child and Adolescent Psychology using keyword searches of abstracts and titles. Articles were classified according to a modified version of the Division 12 task force guidelines that was used in other reviews in this series. The results revealed that findings are becoming increasingly nuanced with variations in levels of evidence related to ages of the children and characteristics of the specific treatment. In addition, we focused our critique on generalization of treatment effects across settings and time and on sample diversity (with regard to ethnicity and levels of parent education) in relation to the population. Children of parents with higher levels of education than average appear to be overrepresented in the literature. Implications for future treatment development and evaluation and for dissemination research are discussed.
Causal inference of gene expression data using a clustering-based extension of Kernel-Granger causality

Detecting causal relationships between time series data has been widely studied in many areas, including biology, neuroscience, economics, and climatology. One of the most popular causality inference methods is Granger causality approach that is a linear regression based model for determining whether one time series is useful in forecasting another; however, this approach cannot detect nonlinear relations in the data. Different extensions of Granger causality have been proposed for nonlinear dynamics of the time series data, which have problems in detecting false discoveries. Recently the properties of kernel algorithms have been used in order to achieve nonlinear evaluations of Granger causality. Real biological datasets have a significant problem which is about the big numbers of genes. However, the time steps in the dataset are very short. Due to this problem, the most algorithm in inferring nonlinear causal relationships would fail. In this paper, we propose a new method that deals with this high dimensionality problem and reduces the size of data. In this method, we cluster the hole data using hierarchical clustering with Euclidian Distance measure. Afterwards, we apply Kernel-Granger causality to a reduced real biological dataset (yeast gene expression data) to infer causal network.

The relative merits of hormone therapy, carotid arteriography, external and interstitial radiation therapy, cryosurgery, and various surgical approaches are discussed.
Accumulation of low density lipoproteins in stimulated rat serosal mast cells during recovery from degranulation.

Stimulation of rat serosal mast cells in vitro with compound 48/80, a degranulating agent, resulted in an immediate increase in binding of low density lipoproteins (LDL) to the stimulated mast cells. The increase in binding was dose-dependent and closely followed the increase in histamine release, i.e., the exocytosis of mast cell granules. It could be demonstrated that the LDL were bound to exocytosed secretory granules which remained cell-associated. During the recovery period the granule-bound LDL were internalized by the mast cells along with the granules. A single stimulation of mast cells rendered their cytoplasm to be filled with granular material showing positive staining for both apoB and neutral lipid. This change was accompanied by a 30-fold increase in the cellular content of cholesteryl esters. Thus, rat serosal mast cells possess a specific mechanism for uptake of LDL that is activated by stimuli that lead to degranulation, the result being massive uptake of LDL by stimulated mast cells during recovery from degranulation.
