An improved staged event driven architecture for Master-Worker network computing

We propose a new design for Master-Worker network computing systems, called the Master-Worker event driven architecture (MEDA). MEDA is an extension of staged event driven architecture and designed for the goal to meet the dynamic demand of Master-Worker model network computing systems, with support for high concurrency, adaptive resources management and modular construction. In MEDA, applications consist of a network of event-driven stages connected by queues. MEDA makes use of a set of dynamic control mechanisms for automatic tuning and load conditioning. Queuing theory is used for thread management mechanism. Application field extends from stand-alone environment to the wide area network environment through the introduction of network queue. Delay event queue realizes the balance of performance and resource consumption. Priority queue expands the availability of job scheduling strategy and improves system efficiency. From experiments of Drug Discovery Grid, these results show that MEDA systems exhibit higher performance, better reliability than Master-Worker network computing system developed using traditional design.
Large-Scale Code Reuse in Open Source Software

We are exploring the practice of large-scale reuse involving at least a group of source code files. Our research question is to determine the extent of such reuse occurring in open source projects, to identify the code that is reused the most, and to investigate patterns of large-scale reuse. We start by identifying a sample of projects involving all code in several large repositories of open source projects, all projects bundled with popular distributions of Linux and BSD, and several large individual projects. In the next step we obtain the source code and identify groups of files reused among projects and determine the code that is most widely reused in our sample. Our findings indicate that more than 50% of the files were used in more than one project. The most widely reused components were small and represented templates requiring major and minor modifications and a group of files reused without any change. Some widely reused components involved hundreds of files.
A modular multisensory prosthetic hand

This paper presents a multi-DOF and multisensory prosthetic hand (HIT V prosthetic hand) with five modular fingers. The hand has a total of 11 joints, which are actuated by 6 intrinsic DC motors. Each digit (2 joints, DIP and MCP, coupled) is driven separately by a motor within the proximal phalange, while the trapeziometacarpal (TM) joint of the thumb is specially devised with an additional actuation in the palm to accomplish adduction/abduction. A type of worm-and-wheel is applied to the metacarpophalangeal (MCP) joints of the five fingers and the TM joint, which can provide a self-locking ability when no motion is internally actuated. Multiple sensors integrated in the distal phalanxes can measure the current position and applied forces of the fingers. The hand control system is composed of two subsystems separately in the finger and in the palm. The finger, integrated with the actuator, the transmission mechanism, the sensory system and the control system as a whole, can obtain abilities to perceive and control all by itself, which provides a technical possibility for partial upper-limb amputees. The hand configuration is specially designed to provide versatile grasps in human's activities of daily living (ADLs). According to the primary experimental results, the technical specifications of the newly-developed prosthetic hand, including the output force and motion velocity, are given in detail. It is validated that the hand can accomplish most of the grasping patterns in our daily lives.
Underestimated Amoebic Appendicitis among HIV-1-Infected Individuals in Japan

ABSTRACT Entamoeba histolytica is not a common causative agent of acute appendicitis. However, amoebic appendicitis can sometimes be severe and life threatening, mainly due to a lack of awareness. Also, its frequency, clinical features, and pathogenesis remain unclear. The study subjects were HIV-1-infected individuals who presented with acute appendicitis and later underwent appendectomy at our hospital between 1996 and 2014. Formalin-fixed paraffin-embedded preserved appendix specimens were reexamined by periodic acid-Schiff (PAS) staining and PCR to identify undiagnosed amoebic appendicitis. Appendectomies were performed in 57 patients with acute appendicitis. The seroprevalence of E. histolytica was 33% (14/43) from the available stored sera. Based on the medical records, only 3 cases were clinically diagnosed as amoebic appendicitis, including 2 diagnosed at the time of appendectomy and 1 case diagnosed by rereview of the appendix after the development of postoperative complications. Retrospective analyses using PAS staining and PCR identified 3 and 3 more cases, respectively. Thus, E. histolytica infection was confirmed in 9 cases (15.8%) in the present study. Apart from a significantly higher leukocyte count in E. histolytica-positive patients than in negative patients (median, 13,760 versus 10,385 cells/μl, respectively, P = 0.02), there were no other differences in the clinical features of the PCR-positive and -negative groups. In conclusion, E. histolytica infection was confirmed in 9 (15.8%) of the appendicitis cases. However, only 3, including one diagnosed after intestinal perforation, were diagnosed before the present analyses. These results strongly suggest there is frequently a failure to detect trophozoites in routine examination, resulting in an underestimation of the incidence of amoebic appendicitis.
Evolution of manifestos in a developing parliamentary democracy with proportional representation and multiparty coalition governments

In exploring the first two decades of evolution of political programmes applied for the electoral processes in Slovenia, a young European multiparty parliamentary democracy with a proportional electoral system and multiparty government coalitions, the article contributes to a rich tradition of studying the programmes of political parties as relevant narrators of the development of democratic systems and suggests an answer to ‘why do parties write manifestos? ’ The main findings include the distinct issue emphasis of parliamentary and non-parliamentary parties’ manifestos and convergence in issue emphasis over time among parliamentary parties who go on to form coalition governments. Regarding the ‘why’, these and other findings indicate that the manifestos considered here are intended more for post-election purposes – in particular, for the formation of alliances and negotiating and running a coalition government – than for attracting voters in the pre-election period. Party programmes are seen more as self-intended tools for political struggle than as promoters or control mechanisms for the further development of the democratic political system.
Extracting Thai Compounds Using Collocations and POS Bigram Probabilities without a POS Tagger

This paper presents a simple method to extract compounds using statistical collocations and POS bigram probabilities without a POS tagger. Statistical collocation was used to determine strength of word co-occurrences. Probabilities of POS sequences were used to adjust the strength of collocation within a possible compound. These probabilities were estimated from compounds found in the dictionary. Bigram and trigram words extracted from a corpus of 28 million words were ranked by two means, collocation scores and collocation scores weighted by POS pattern probabilities. Cutoff precision at every 200 points were calculated for both methods. The results showed that probabilities of POS sequences could increase the precision rate of compound extraction at certain level. The system can extract 2-word compounds and 3-word compounds at the precision rate up to 63% and 35% respectively. When eliminating bigram extractions that could be parts of trigram extraction, the precision rate is increased up to 71%.
Gene expression pattern Differential expression of Tbx4 and Tbx5 in Zebrafish fin buds

In here we report the identification of two new members of the T-box gene family, zf-tbx5 and zf-tbx4, from the Zebrafish, Danio rerio. The amino acid sequences within the T-box domain share high homology with the mouse, chick, and newt orthologs. Whole mount in situ hybridization revealed specific expression of these genes in the eye and Fin buds. zf-tbx5 expression is restricted to the pectoral Fin bud, whilst zf-tbx4 transcripts are confined in the pelvic Fin bud. These results reveal the conserved expression pattern of Tbx5 and Tbx4 during appendage development in all animal species studied to date. q 1999 Elsevier Science Ireland Ltd. All rights reserved.
Minimum cost seed set for competitive social influence

We wonder that in a competitive environment, how an influence uses the minimum cost to choose seeds such that its influence spread can reach a desired threshold under thwarting from its competitors. At first we take a simple fact into account: the information arriving first has heavy impact, and present Competitive - Independent Cascade (C-IC) model to characterize how different influences competing with others in a social network. We have found that a specific influence's spread is monotone and submodular, and these nice properties make algorithm performance tractable. We then propose Minimum Cost Seed Set problem (MinSeed) to answer our original concern and give a greedy algorithm. We analyze the ratio of greedy algorithm, and give result significantly better than similar ones analyzed by others. Noticing that the computation of real information spread is hard to compute and simple greedy is too time consuming, we design an effective method for estimating information spread in C-IC model, and devise scalable algorithm applying for large social networks. Through simulation on real world datasets, we confirm that, our scalable algorithm outputs seed set with small total cost comparable to that given by simple greedy, with very fast computation.
The stromelysin-1 5A/5A genotype enhances colorectal cancer cell invasion in Iranian population

Background: Matrix metalloproteinases comprise a family of enzyme degrade components of extra cellular matrix. There are single nucleotide polymorphisms in the promoter regions of several genes with ability to influence cancer susceptibility. The aim of this study was to analyze association between MMP3 promoter polymorphisms and colorectal cancer occurrence and progression. Materials and Methods: In this case-control study 120 colorectal cancer patients and 100 controls were genotyped using polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) on the genomic deoxyribonucleic acid (DNA). The patients group was divided into different subgroups: a subgroup without metastatic activity (M-) and a subgroup that had developed metastasis (M+). Results: There was a significant difference in frequency of the MMP-3 genotype between cases and controls (χ΂ = 16.17; P = 0.0003). The 5A homozygote in patients and controls was significantly different. The frequency of the 5A allele among affected patients (67.91%) was significantly higher than among the healthy controls (49%; χ2 = 16.17, P = 0.00005). At the time of diagnosis, individual who was carrying the 5A allele was more represented in the M+ subgroup than in M- subgroup (χ² = 7.49; P = 0.006, OR = 3.86; 95% CI, 1.43–10.33). The difference between M- and controls did not observe statistically significant (χ² = 0.009; P = 0.92). Conclusions: Our results suggest that the presence of 5A polymorphism at the MMP-3 promoter region may favor the growth and the metastasis process in colorectal cancer patients and could be looked at as a risk factor for a worse prognosis.
Automated Design Debugging With Maximum Satisfiability

As contemporary very large scale integration designs grow in complexity, design debugging has rapidly established itself as one of the largest bottlenecks in the design cycle today. Automated debug solutions such as those based on Boolean satisfiability (SAT) enable engineers to reduce the debug effort by localizing possible error sources in the design. Unfortunately, adaptation of these techniques to industrial designs is still limited by the performance and capacity of the underlying engines. This paper presents a novel formulation of the debugging problem using MaxSAT to improve the performance and applicability of automated debuggers. Our technique not only identifies errors in the design but also indicates when the bug is excited in the error trace. MaxSAT allows for a simpler formulation of the debugging problem, reducing the problem size by 80% compared to a conventional SAT-based technique. Empirical results demonstrate the effectiveness of the proposed formulation as run-time improvements of 4.5 × are observed on average. This paper introduces two performance improvements to further reduce the time required to find all error sources within the design by an order of magnitude.
Bloch-mode analysis for retrieving effective parameters of metamaterials

We introduce an approach for retrieving effective parameters of metamaterials based on the Bloch-mode analysis of quasiperiodic composite structures. We demonstrate that, in the case of single-mode propagation, a complex effective refractive index can be assigned to the structure, being restored by our method with a high accuracy. We employ both surface and volume averaging of the electromagnetic fields of the dominating (fundamental) Bloch modes to determine the Bloch and wave impedances, respectively. We discuss how this method works for several characteristic examples, and demonstrate that this approach can be useful for retrieval of both material and wave effective parameters of a broad range of metamaterials.
CHAPTER 31 Positive Psychology

I n its relatively brief history, positive psychology has used a variety of research method­ ologies to better understand the nature of happiness and the "good life. " In the face of scant empirical knowledge of positive emotions (cf. tightly controlled randomized laboratory studies have begun to establish the causes, cor­ relates, consequences, and basic mechanisms underlying positive emotions and global happiness. Such experiments represent a significant advance over the correlational survey studies that informed researchers' understanding of well-being for decades. In the pur­ suit of triangulation, an important next step is to examine the real-world circumstances under which people feel good and thrive. According to Seligman and Csikszentmihalyi (2000), "Psychology should be able to help document what kinds of families result in children who flourish, what work settings support the greatest satisfaction among work­ ers, what policies result in the strongest civic engagement, and how people's lives can be most worth living" (p. 5). Realizing these goals requires the study of positive experi­ ences and positive emotions in everyday life and in real time. Not coincidentally, perhaps, experience sampling methods, which are used to assess aspects of daily life as they occur in the moment, have their origins in positive psychologyhave been the focus of research in positive psychology, the majority of studies have examined happiness, or subjective well-being. Consequently, this chapter focuses on methodological advancements in the area of well-being. However, as we argue later, such methods are ripe to be extended and applied to other positive psychological constructs as well.
Vision based system for camera tracking in eye-in-hand configuration

This paper presents an effective approach to estimate the fixed internal and varying external parameters of the camera for real time experiments using 2D-3D point correspondences. Images are acquired at each time step, a pose estimation algorithm is then employed to determine the camera pose w.r. t the object. A simple homogenous transformation is derived between the camera and end-effector to determine the position of the manipulator end-effector, as camera is mounted on the tool in eye-in-hand configuration. The paper focuses on determining the pose accurately and to look upon those issues that we encounter in real time. The major contribution of this paper is in two folds: camera pose parameters are easily and accurately recovered from 2D to 3D point correspondence; second is that experiments using real images are conducted, which presents good results.
Why We Need to Extend the Classical Model of Brand Personality: The Practical Value of Brand Personality Measuring Tool for Marketers

The brand personality is a very popular area of research in marketing. Consumers perceive brands as if they were living beings. They assign to brands positive and negative personal traits, demographic characteristics, physical characteristics and cognitive skills. The personality of the brand is a very important means of differentiation, which is the most difficult to copy. Although this topic has been popular in in theoretical marketing research for a long time, little has been done to implement brand personality measuring tool in practice. The author dealt with the methodological shortcomings of a large number of brand personality studies and presented an extended model of "brand as a person," which, in addition to personality traits includes other determinants of the brand as a person, in order to enhance the practical use of this measuring tool. The author has conducted her own research of the extended personality profile of brands of mobile operators in Serbia (telecommunications sector), including two international companies and one domestic company, in order to determine the diagnostic and predictive value of extended brand personality measuring tool. By determining a broader profile of the "brand as a person" (current or desired), we can clearly perceive: if the diversity of the brand compared to other similar brands is sufficient, where we made the mistakes, and how we can focus brand positioning in the future, using a variety of marketing tools.
An ultra-wideband D-Band signal source chip using a fundamental VCO with frequency doubler in a SiGe bipolar technology

This paper presents an ultra-wideband signal source chip for the D-Band in a SiGe:C bipolar production technology with an fT of 170 GHz and fmax of 250 GHz. The presented architecture consists of a fundamental VCO with a frequency doubling output stage. The goal of this work is to achieve a signal source near the technologies cut-off frequency while providing good performance concerning phase noise, bandwidth, and output power simultaneously. The chip facilitates a 3 dBm peak output power and a 3 dB bandwidth of 39 GHz. The phase noise at 1 MHz offset is -93 dBc/Hz at 147 GHz (and better than -89 dBc/Hz in a wide frequency range of 39 GHz). The results are achieved with a power consumption of 410 mW from a 5 V supply.
Reusing Speech Techniques for Video Semantic Indexing [Applications Corner]

Many techniques developed in speech research have been successfully employed in other fields, such as automatic video semantic indexing. In this application, a user submits a textual input query for an desired object or a scene to a search system, which returns video shots that include the object or scene. Recently, a new method using Gaussian-mixture model (GMM) supervectors and support vector machines (SVMs) was proven to be very effective. In this method, speech technology such as speaker verification and adaptation techniques play very important roles.
A Faster Parameterized Algorithm for Pseudoforest Deletion

A pseudoforest is a graph where each connected component contains at most one cycle, or alternatively, a graph that can be turned into a forest by removing at most one edge from each connected component. In this paper, we show that the following problem can be solved in O(3^k n k^{O(1)}) time: given a graph G and an integer k, can we delete at most k vertices from G such that we obtain a pseudoforest? The result improves upon an earlier result by Philip et al. [MFCS 2015] who gave a (nonlinear) 7.56^k n^{O(1)}-time algorithm both in the exponential factor depending on k as well as in the polynomial factor depending on n.
1 AUTONOMOUS FAULT DETECTION ON A LOW COST GPS-AIDED ATTITUDE DETERMINATION SYSTEM

This paper presents a three-axis attitude determination procedure based on the Global Positioning System (GPS) with special emphasis to the autonomous integrity monitoring issue. One envisages a class of low cost navigation applications requiring low accurate (around 0.5 degrees) but continuous attitude knowledge. A snapshot algorithm first estimate the three-axis attitude from interferometry on double differences of GPS carrier phase L1. Then, the attitude estimate is improved by fusing it with angular rate measurements from low cost, MEMS gyros. The procedure is especially designed to detect single faults on either the GPS or the gyros autonomously from residuals monitoring. Both GPS and gyro measurements are taken as corrupted by colored Gaussian noises whose effects are mitigated by a stochastic dynamic compensation model. The state vector, which includes the attitude quaternion and parameters of the error model, is estimated from a bank of extended Kalman filters with different time delays. Attitude propagation model between GPS sampling times is based on the gyro output after drift calibration. One defines the fault modes of each sensor and some control parameters to the fault detection procedure.The algorithm is tested with numerical simulation and real data. The simulation scenarios include LEO micro-satellites with different orbit inclinations and three different failure modes: complete out track from the whole GPS constellation; temporary abnormal interference on a single GPS satellite; and gyro drift higher than its specified level. The results show that the algorithm is suitable to cope with different fault types and intensity levels.
Risk factors that influence suicidal behavior in affective disorders

It is known in the literature that the incidence and prevalence of suicide and attempted suicide in psychiatric patients is significantly higher than in the general population. The paper examined risk factors for suicidal behavior in the category of admitted patients hospitalized with the diagnosis of sleep disorders and affective (Unipolar resp. Bipolar depression). Study activated by 80 patients, 40 in both diagnostic groups received treatment at the Special Psychiatric Hospital in Gornja Toponica near Nis. The work methodology used are: psychiatric interview, Hamilton Depression Rating Scale (HAMD), and the C-SSRS (Columbia-Suicide Severity Rating Scale)- assessment tool that assesses suicidal ideation and behavior. The study results show that there is a relationship between suicidal behavior (suicide attempts and suicidal ideation) and the diagnosis of bipolar affective disorder, positive history of previous suicide attempts, so that these factors are stronger, to the degree of suicidality higher. On this sample, clearly suicidal behavior, with the same purpose, intensity of suicidal thoughts and medical impairment after suicide attempts were significantly more frequent in patients with Bipolar Affective Disorder in the depressive phase of the illness. Patients with a previous suicide attempt, and poor personal and social circumstances had a higher rate of attempted suicide.
