Room‐Temperature Metallic Fusion‐Induced Layer‐by‐Layer Assembly for Highly Flexible Electrode Applications

To fabricate flexible electrodes, conventional silver (Ag) nanomaterials have been deposited onto flexible substrates, but the formed electrodes display limited electrical conductivity due to residual bulky organic ligands, and thus postsintering processes are required to improve the electrical conductivity. Herein, an entirely different approach is introduced to produce highly flexible electrodes with bulk metal–like electrical conductivity: the room‐temperature metallic fusion of multilayered silver nanoparticles (NPs). Synthesized tetraoctylammonium thiosulfate (TOAS)‐stabilized Ag NPs are deposited onto flexible substrates by layer‐by‐layer assembly involving a perfect ligand‐exchange reaction between bulky TOAS ligands and small tris(2‐aminoethyl)amine linkers. The introduced small linkers substantially reduce the separation distance between neighboring Ag NPs. This shortened interparticle distance, combined with the low cohesive energy of Ag NPs, strongly induces metallic fusion between the close‐packed Ag NPs at room temperature without additional treatments, resulting in a high electrical conductivity of ≈1.60 × 105 S cm−1 (bulk Ag: ≈6.30 × 105 S cm−1). Furthermore, depositing the TOAS–Ag NPs onto cellulose papers through this approach can convert the insulating substrates into highly flexible and conductive papers that can be used as 3D current collectors for energy‐storage devices.
Detecting common copy number variants in high-throughput sequencing data by using JointSLM algorithm

The discovery of genomic structural variants (SVs), such as copy number variants (CNVs), is essential to understand genetic variation of human populations and complex diseases. Over recent years, the advent of new high-throughput sequencing (HTS) platforms has opened many opportunities for SVs discovery, and a very promising approach consists in measuring the depth of coverage (DOC) of reads aligned to the human reference genome. At present, few computational methods have been developed for the analysis of DOC data and all of these methods allow to analyse only one sample at time. For these reasons, we developed a novel algorithm (JointSLM) that allows to detect common CNVs among individuals by analysing DOC data from multiple samples simultaneously. We test JointSLM performance on synthetic and real data and we show its unprecedented resolution that enables the detection of recurrent CNV regions as small as 500 bp in size. When we apply JointSLM to analyse chromosome one of eight genomes with different ancestry, we identify 3000 regions with recurrent CNVs of different frequency and size: hierarchical clustering on these regions segregates the eight individuals in two groups that reflect their ancestry, demonstrating the potential utility of JointSLM for population genetics studies.
Model-Free Visually Servoed Deformation Control of Elastic Objects by Robot Manipulators

Despite the recent progress in physically interactive and surgical robotics, the active deformation of compliant objects remains an open problem. The main obstacle to its implementation comes from the difficulty to identify or estimate the object's deformation model. In this paper, we propose a novel vision-based deformation controller for robot manipulators interacting with unknown elastic objects. We derive a new dynamic-state feedback velocity control law using the passivity-based framework. Our method exploits visual feedback to estimate the deformation Jacobian matrix in real time, avoiding any model identification steps. We prove that even in the presence of inexact estimations, the closed-loop dynamical system ensures input-to-state stability (i.e., full dissipativity) with respect to external disturbances. An experimental study with several deformation tasks is presented to validate the theory.
q-conformal invariant equations and q-plane wave solutions

We give new solutions of the quantum conformal deformations of the full Maxwell equations in terms of deformations of the plane wave. We study the compatibility of these solutions with the conservation of the current. We also start the study of quantum linear conformal (Weyl) gravity by writing the corresponding q-deformed equations.

Evaluation of central analgesic efficacy with two experimental models was the hot-plate method and white needle-guided method for the n-hexane extract and ethyl acetate fraction of Sanchezia nobilis Hook.f. leaves collected in Nam Dinh province. The study results show that by oral administration, at a dose of 64 mg/kg/day, 192 mg/kg/day for n-hexane and 16 mg/kg/day, 48 mg/kg/day for ethyl acetate fraction, for 7 consecutive days, the ethyl acetate fraction had more pronounced central analgesic effect than the n-hexane fraction.
A latent semantic indexing and WordNet based information retrieval model for digital forensics

It is well known that either domain specific or domain independent knowledge has been adopted in Information retrieval (IR) to improve the retrieval performance. In this paper, we propose a novel IR model for digital forensics by using latent semantic indexing (LSI) and WordNet as an underlying reference ontology to retrieve suspicious emails according to the semantic meaning of an investigatorpsilas query. Our model incorporates corpus independent knowledge from WordNet and corpus dependent knowledge from LSI into query expansion and reduction; and LSI is also adopted to simulate human meaning based judgement of relatedness between investigatorpsilas queries and emails. We compare the performance of the resulting LSI And WordNet based Information retrieval system (LAWIRS) with other three systems we implement, i.e. the LSI system, the Lucene system and the Lucene system with query expansion. Experimental results on several email datasets demonstrate that for short Boolean queries, LAWIRS can successfully capture their meaning and yield substantial improvements in the overall retrieval performance.
Multimodal Dialog System Using Hidden Information State Dialog

This demo presents a multimodal dialog system that uses Hidden Information State (HIS) approach to manage the human-machine multimodal interaction. HIS dialog manager is a variation of classic Partially Observable Markov Decision Process (POMDP), which provides one of the statistical dialog modeling frameworks. But it has been hard to apply POMDP to the real domain of dialog system since POMDP-based dialog management requires very large size of state space. With HIS approach, system groups the belief states to reduce the size of state space, so that HIS dialog manager can be used in practical dialog systems. We adopted HIS dialog manager to our smart-home control domain multimodal dialog system that supports speech and pen gesture as input channels.
Mate Selection in Heterosexual Relationships: A Study of Gender Differentiation among Students in Greece

The article discusses gender differentiation of mate selection criteria in heterosexual relationships, presenting the findings of a survey conducted in Greece among 77 students aged 19-29 who attend the Department of Social Work in the University of West Attica. The gender variable was the control variable for research cases and was used in the interpretation of the results. The results showed that in this particular group of educated young people differences in preferences in mate selection between men and women tend to be eliminated as a source of social development in the field of women's position and gender socialization.
Maintaining Task Set Against Distraction: The Role of Working Memory in Multitasking

Multitasking, a common feature of everyday life, requires simultaneous maintenance and operation of a range of action-controlling task sets. We investigated the role of working memory in multitasking by means of the embedded task paradigm. This involved setting up a primary task with a variable task set, which then had to be maintained throughout the performance of a second embedded task with a fixed task set before it could be completed. We tested the hypothesis that the capacity to maintain the 2 task sets so as to avoid mutual interference would depend on working memory. We used Baddeley and Hitch’s (1974) multicomponent working memory approach to investigate this. Experiment 1 used articulatory suppression to examine the potential role of subvocal rehearsal, and found no impact on performance. Experiment 2 used backward counting to impose an additional executive load, and found a major impact on performance even with the simple task of counting backward in ones. This took the form of more pervasive effects of stimulus overlap that could be interpreted in terms of a change in the way the two tasks were managed. The differential impacts of the concurrent tasks indicated that multitasking is dependent on working memory, where it draws on limited-capacity executive resources but not on the capacity for temporary phonological storage.
Computational soundness of observational equivalence

Many security properties are naturally expressed as indistinguishability between two versions of a protocol. In this paper, we show that computational proofs of indistinguishability can be considerably simplified, for a class of processes that covers most existing protocols. More precisely, we show a soundness theorem, following the line of research launched by Abadi and Rogaway in 2000: computational indistinguishability in presence of an active attacker is implied by the observational equivalence of the corresponding symbolic processes. We prove our result for symmetric encryption, but the same techniques can be applied to other security primitives such as signatures and public-key encryption. The proof requires the introduction of new concepts, which are general and can be reused in other settings.
A Method of Performance Analysis and Verification of Real-Time System Based on Model Checking

Performance analysis of software designs is particularly important for real-time system, quantitative analysis of a real-time system design allows the early detection of potential performance problems. This paper proposes a method of performance analysis and verification of real-time system which is based on model checking UML collaboration model. Firstly, task architecture of real-time system is created by an event sequence diagram which is based on a concurrent collaboration diagram. And then allocate time budget to the concurrent tasks in the system and convert the concurrent collaboration diagram to networks of timed automata in UPPAAL for automatic analysis and verification.
Analysis of synchrony of a handshake between humans

Physical and social interaction between humans and robots are important for humanoid robotics. In this article the characteristics of a handshake between humans are physically examined aiming at future experiments with a handshake between a human and a robot. A special pair of data gloves has been designed to measure quantitative characteristics of a handshake ritual such as duration, strength of the grip, and frequency of the rhythmic movements. Experiment results show that handshaking consists of four phases. After a physical contact, a mutual synchrony appears between the two persons. A statistical analysis shows that the frequency of this synchronization is around 4 Hz and average strength of the grip is 2.5 N.
Limited Failure Censored Life Test Sampling Plan: Pareto-Rayleigh Model

A combination of Pareto and Rayleigh distributions considered for a new T-X probability model named as Pareto-Rayleigh distribution (PR distribution). We have chosen a life time random variable X from PR distribution whose lots are to be decided for acceptance or otherwise based on sample lifetimes drawn from the lot. A sampling scheme is developed in such way that the sample is divided into different groups and experiment is terminated whenever the first failure noticed in each group. The theory of ordered statistics is applied for the criterion of acceptance and is compared with the similar works proposed by other authors.
Fertility practitioners' experience of the psychological sequelae of unmet parental goals after unsuccessful fertility treatment : a Delphi Consensus Study

This thesis investigates the adjustment processes to involuntary childlessness and the psychological distress associated with unmet parental goals. Paper one reports a systematic review of quantitative studies looking at how trauma theory informs the clinical understanding of adjustment to involuntary childlessness. This yielded eight studies which were reviewed and rated using a quality appraisal tool. The data extracted, focused on the prevalence of trauma and post traumatic growth to infertility. No studies included, focused their research on cohorts of women who identified as being involuntarily childless through delayed childbearing or circumstantial reasons. The findings suggested that for women who are, infertile, who had accessed or were accessing fertility treatment and were childless, trauma theory can aid clinical understanding of both their experience of infertility distress and adjustment to involuntary childlessness. Paper two describes a three round, online Delphi Study which investigated, infertility practitioners’ clinical experience of psychological distress associated with unmet parental goals, following unsuccessful fertility treatment. Nine practitioners, from five countries participated, rating 58 statements on the presentation and nature of distress observed in the post treatment phase. Infertility practitioners perceived distress to be associated with statements concerned with individual’s identity and relinquishing the desire for biological children. The fertility practitioners agreed that the core element of therapy was to facilitate meaning making, acceptance and pursuit of new life goals. Paper three provides a critical account of the strengths and limitations of both the systematic review and empirical paper. The theoretical and clinical implications of the research included addressing pertinent issues, which arose during the research process. Finally, the competencies developed from conducting this research will be described in relation to becoming a clinical psychologist.
Revisit the Analog Computer and Gradient-Based Neural System for Matrix Inversion

As inspired by revising (Zhang and Ge, 2003), the traditional gradient-based neural system (also termed analog computer (Manherz et al., 1968)) for matrix inversion is re-visited by examining different activation functions and various implementation errors. A general neural system for matrix inversion is thus presented which can be constructed by using monotonically-increasing odd activation functions. For superior convergence and robustness of such a system, the power-sigmoid activation function is preferred to be in use if the hardware permits. In addition to investigating the singular case, this paper also presents an application example on inverse-kinematic control of redundant manipulators via online pseudoinverse solution
(±)3,4-Methylenedioxymethamphetamine (‘Ecstasy’)-Induced Serotonin Neurotoxicity: Studies in Animals

The popular recreational drug, (±)3,4-methylenedioxymethamphetamine (MDMA; ‘Ecstasy’) is a potent and selective brain serotonin (5-HT) neurotoxin in animals. MDMA-induced 5-HT neurotoxicity can be demonstrated using a variety of neurochemical, neuroanatomical and, more recently, functional measures of 5-HT neurons. Although the neurotoxic effects of MDMA in animals are widely accepted, the relevance of the animal data to human MDMA users has been questioned, largely because dosages of drugs used in animals are perceived as being much higher than those used by humans. In the present paper, we review the extensive body of data demonstrating that MDMA produced toxic effects on brain 5-HT neurons in animals and present new data indicating that levels of the type 2 vesicular monoamine transporter are reduced in MDMA-treated animals, providing further indication of MDMA’s 5-HT neurotoxic potential. Further, we demonstrate, using principles of interspecies scaling, that dosages of MDMA known to be neurotoxic in animals fall squarely in the range of dosages used typically by recreational MDMA users.
Torsion as Alternative to Curvature in the Description of Gravitation

The general covariance principle, seen as an active version of the principle of equivalence, is used to study the gravitational coupling prescription in the presence of curvature and torsion. It is concluded that the coupling prescription determined by this principle is always equivalent with the corresponding prescription of general relativity. An application to the case of a Dirac spinor is made.
Color correction based image blending for creating high resolution panoramic images on mobile devices

We present a color correction based image blending approach which is capable of combining a set of aligned source images to a composite image and implement it in a mobile panorama system for creating high-resolution panoramic images on mobile devices. Our color correction is performed in the gamma-corrected RGB color space [2009a]. A global adjustment process is used for smoothing color transition in the whole image sequence and reducing cumulative errors. Unlike the work [2009a] which focuses on solving pixel saturation problems in using diagonal models [2002] in the RGB color space, here we are focusing on improving the blending quality and speed for long image sequences. We compare results and performance with a global blending approach [2009b] to demonstrate advantages of the color correction based image blending approach in creating high-resolution panoramic images on mobile devices.
Therapeutic commitment for general nurses in dealing with mental health problems of people living with HIV/AIDS in Blantyre, Malawi.

INTRODUCTION Therapeutic commitment of general nurses influences their provision of mental health care to clients. It is the general nurses' predisposition for working therapeutically with clients who have mental health problems (MHPs). In Malawi, general nurses are the majority of health care professionals who care for people living with HIV/AIDS (PLWHA) and they are expected to deal with the mental health problems of these patients. The provision of mental health care to PLWHA is vital because apart from the physical illnesses associated with the virus, these people are also affected by mental health problems. However, most general nurses, feel neither confident nor competent when dealing with the mental health problems of their clients in Malawi. This may negatively influence their therapeutic commitment in dealing with mental health problems of PLWHA. However, therapeutic commitment of general nurses in providing mental health care to PLWHA in Malawi remains unknown. MATERIALS AND METHODS The study used a quantitative descriptive survey design. a convenient sample comprising of 136 general nurses was used and data was collected using Mental Health Problems Perception Questionnaire. Permission to use the tool in this study was granted by Prof. Lauder. Ethical approval to conduct the study was granted by Ethics Committees at University of KwaZulu Natal and University of Malawi. Data were analysed using Statistical Package for Social Sciences version 15.0. RESULTS The study findings revealed that there is a linear relationship between general nurses' levels of knowledge and skills and their therapeutic commitment (r=.40, n=136, p<.05) to provide mental health care of PLWHA. CONCLUSION This study suggests general nurses' levels of therapeutic commitment in dealing with MHPs of PLWHA vary and their levels of knowledge and skill to deal with MHPs influence their willingness to provide mental health care to PLWHA.
Treatment of Helicobacter pylori Infection in Korea: A Systematic Review and Meta-analysis

The efficacy of seven-day clarithromycin-based standard triple therapy (STT) for Helicobacter pylori has decreased in Korea over the past decade. The aim of this meta-analysis was to clarify the efficacy of first-line and second-line therapies in Korea. This systematic review will provide an overview of H. pylori eradication and present new therapeutic strategies used in Korea. An extensive search of the literature concerning STT, sequential therapy (SET), concomitant therapy (CT), bismuth-containing quadruple therapy (BCQT) and various other therapies used in Korea was performed. All selected studies were randomized controlled trials (RCTs). Eighteen RCTs were eligible for systematic review. The alternative regimens comparing seven-day STT as a first-line therapy include SET, CT, levofloxacin-based therapy (LBT), BCQT, and STT with prolonged duration. The results of the meta-analysis suggest that SET is superior to seven-day STT. The overall eradication rate by intention to treat (ITT) analysis was 69.8% for STT and 79.7% for SET. The overall eradication rate by per-protocol (PP) analysis was 77.0% for STT and 85.0% for SET. The odds ratios for the ITT and PP eradication rate were 0.57 (95% confidence interval [CI], 0.43 to 0.74) and 0.52 (95% CI, 0.35 to 0.76), respectively. In the subgroup analysis, however, there were no significant differences between SET and STT with prolonged durations. Alternative regimens to seven-day BCQT as second-line therapy include LBT, moxifloxacin-based therapy and 14-day BCQT. The eradication rates of these alternative regimens were not superior to that of the conventional treatment. SET is superior to seven-day STT but not to STT with prolonged duration.

Assessing Software Maintainability Based on Class Diagram Design: A Preliminary Case Study

 Abstract—Can software maintainability be assessed at the early design stage? For a preliminary answer, we conducted a case study. The study adopts a set of metrics for class diagram measurement, and defines three indices for maintainability assessment from the defect-correction perspectives. The dataset under investigation includes the defect repository and corrective maintenance history of Apache Tomcat (maintained from 2006 to 2014). Statistical findings show that some class diagram metrics (such as the number of class association across packages, the number of classes, the inheritance depth for a class et al.) are significantly correlated with the maintainability assessment in this software. The result can guide maintenance-oriented software design, and also motivates us to do a stronger empirical evaluation. 
Desiccation Tolerance of Five Tropical Seedlings in Panama. Relationship to a Field Assessment of Drought Performance1

Studies of the desiccation tolerance of the seedlings of five tropical trees were made on potted plants growing in a greenhouse. Pots were watered to field capacity and then dehydrated for 3 to 9 weeks to reach various visual wilting stages, from slightly wilted to dead. Saturated root hydraulic conductance was measured with a high-pressure flowmeter, and whole-stem hydraulic conductance was measured by a vacuum chamber method. Leaf punches (5.6-mm diameter) were harvested for measurement of leaf water potential by a thermocouple psychrometer method and for measurement of fresh and dry weight. In a parallel study, the same five species were studied in a field experiment in the understory of a tropical forest, where these species frequently germinate. Control seedlings were maintained in irrigated plots during a dry season, and experimental plants were grown in similar plots with rain exclusion shelters. Every 2 to 4 weeks, the seedlings were scored for wilt state and survivorship. After a 22-week drought, the dry plots were irrigated for several weeks to verify visual symptoms of death. The field trials were used to rank drought performance of species, and the greenhouse desiccation studies were used to determine the conditions of moribund plants. Our conclusion is that the desiccation tolerance of moribund plants correlated with field assessment of drought-performance for the five species (r2 > 0.94).
