Gating Recurrent Enhanced Memory Neural Networks on Language Identification

This paper proposes a novel memory neural network structure, namely gating recurrent enhanced memory network (GREMN), to model long-range dependency in temporal series on language identification (LID) task at the acoustic frame level. The proposed GREMN is a stacking gating recurrent neural network (RNN) equipped with a learnable enhanced memory block near the classifier. It aims at capturing the long-span history and certain future contextual information of the sequential input. In addition, two optimization strategies of coherent SortaGrad-like training mechanism and a hard sample score acquisition approach are proposed. The proposed optimization policies drastically boost this memory network based LID system, especially on the large disparity training materials. It is confirmed by the experimental results that the proposed GREMN possesses strong ability of sequential modeling and generalization, where about 5% relative equal error rate (EER) reduction is obtained comparing with the approximate-sized gating RNNs and 38.5% performance improvements is observed compared to conventional i-Vector based LID system.
An Innovative Electro-Optical Chaotic System Using Electrical Mutual Injection With Nonlinear Transmission Function

In the purpose of improving the complexity and the security of chaotic communication system, a novel electro-optical intensity chaotic system using electrical mutual injection with nonlinear transmission function is proposed. The electro-optical intensity chaotic system consisting of two delay feedback branches in a serial configuration extends keys space scale. The dynamic characteristics of the proposed system are investigated by means of the bifurcation diagram, the largest Lyapunov exponents, and the permutation entropy, and the security are also analyzed through the autocorrelation function and the delayed mutual information. The simulation results show that the proposed system can acquire higher complexity and the better security, compared with the recent ones. The scheme allows the system to enter chaos with a low gain and the time-delay concealed effectively due to a nonlinear transmission function. Besides, the communication synchronization on basis of the proposed system is discussed. It comes to a conclusion that the proposed chaotic system has potential applications in secure communications.
MIREX: MapReduce Information Retrieval Experiments

We propose to use MapReduce to quickly test new retrieval approaches on a cluster of machines by sequentially scanning all documents. We present a small case study in which we use a cluster of 15 low cost machines to search a web crawl of 0.5 billion pages showing that sequential scanning is a viable approach to running large-scale information retrieval experiments with little effort. The code is available to other researchers at: http://sourceforge.net/projects/mirex/
Design and Stability Analysis of Supervisor-based Adaptive Fuzzy Logic Control System for Temperature

The application of fuzzy logic (FL) supervisors (FLS) for on-line nonlinear auto-tuning of the basic FL controllers (FLCs) gains popularity as a simple adaptive technique for improvement of the performance of control systems for plants with nonlinearities, inertia, time-delay, model uncertainty and variable parameters. Various approaches for the FLS design are developed for different types of FLCs and performance measures considered. However, structure simplification techniques and closed loop system stability analysis are needed to promote the FLC -FLS industrial applications which constitute the aim of the present work. A parallel distributed compensation (PDC) equivalent in operation to the FLC-FLS is suggested that consists of a Sugeno model for fuzzy blending of the outputs of several linear PID controllers depending on the operation point. The PID parameters are optimized using genetic algorithms, simulations, experimental data and random inputs. The simpler in structure PDC-PID control system is validated as equivalent in operation to the supervisory control system and also its stability is proven by deriving Lyapunov conditions and solving them using linear matrix inequalities (LMI) numerical technique. All investigations are performed on the example of the control of the air temperature in a laboratory dryer using MATLAB and its real time facilities.
EFFECT OF CAMEL MILK ON GLYCEMIC CONTROL, RISK FACTORS AND DIABETES QUALITY OF LIFE IN TYPE-1 DIABETES: A RANDOMISED PROSPECTIVE CONTROLLED STUDY

The aim of the study was to evaluate the efficacy of camel milk on glycemic control, risk factors and quality of life in patients of type 1 diabetes. Twentyfour randomly selected patients with type 1 diabetes were enrolled in the study. These patients were divided into two groups. Group 1 (n=12) received usual care (diet, exercise and insulin) and group 2 (n=12) received 500 ml camel milk in addition to usual care, for a period of three months. Frequent blood sugar monitoring was done to maintain euglycemia by titrating the doses of insulin. HbA1C, Lipid profile, plasma insulin and C-peptide estimation was done at the beginning and after 3 months. BMI and diabetes quality of life questionnaire were evaluated weekly. In each visit, the patient was queried for any untoward effects after starting camel milk. Baseline data of both the groups were similar in demographic and clinical variables. After 3 months of treatment there was a significant improvement in fasting blood sugar (115.7 + 7.2 to 100 + 16.2, p<0.002), HbA1C levels (9.54 + 2.1 to 9.08 + 1.77, p<0.002) and a significant reduction in insulin requirement (mean doses of insulin 41.2 + 10.3 to 30 + 12.6 units, p<0.002) in patients receiving camel milk. Diabetes quality of life score improved significantly in the form of change in satisfaction score from 28 + 5.16 to 22.5 + 3.96 (p<0.002), impact score from 34 + 4.84 to 28.08 + 5.26 (p<0.003) and worry score from 15.5 + 3.2 to 11.91 + 1.24 (p<0.002). There was 30% reduction in doses of insulin in 92% of patients of group 2. However, there were no statistically significant changes in lipid profile, plasma insulin and C-peptide levels. Camel milk is an effective supplementation in the management of type 1 diabetes as there was significant reduction in doses of insulin along with betterment in BMI and diabetes quality of life. However, there was no change in lipid profile and insulin levels.
CETS : Compiler-Enforced Temporal Safety for C Santosh Nagarakatte Jianzhou

Temporal memory safety errors, such as dangling pointer dereferences and double frees, are a prevalent source of software bugs in unmanaged languages such as C. Existing schemes that attempt to retrofit temporal safety for such languages have high runtime overheads and/or are incomplete, thereby limiting their effectiveness as debugging aids. This paper presents CETS, a compile-time transformation for detecting all violations of temporal safety in C programs. Inspired by existing approaches, CETS maintains a unique identifier with each object, associates this metadata with the pointers in a disjoint metadata space to retain memory layout compatibility, and checks that the object is still allocated on pointer dereferences. A formal proof shows that this is sufficient to provide temporal safety even in the presence of arbitrary casts if the program contains no spatial safety violations. Our CETS prototype employs both temporal check removal optimizations and traditional compiler optimizations to achieve a runtime overhead of just 48% on average. When combined with a spatial-checking system, the average overall overhead is 116% for complete memory safety.

The Chitinolytic Activity of Listeria monocytogenes EGD Is Regulated by Carbohydrates but Also by the Virulence Regulator PrfA

ABSTRACT Chitin, an insoluble polymer of N-acetyl-d-glucosamine (GlcNAc), is one of the most abundant carbohydrate polymers in marine and terrestrial environments. Chitin hydrolysis by Listeria monocytogenes depends on two chitinase-encoding genes, chiA and chiB, and the aim of this study was to investigate their regulation. Chitin induces the expression of both chitinases in late exponential growth phase, and chiA but not chiB is furthermore induced by the monomer GlcNAc. Furthermore, their expression is subjected to catabolite control. Chitinases expressed by bacterial pathogens have proven to be important not only for nutrient acquisition and environmental survival but also for infecting animals and humans. Interestingly, the central L. monocytogenes virulence gene regulator, PrfA, is required for the chitinolytic phenotype, as chitinase activity was significantly reduced in prfA mutant cells compared to its level in wild-type cells. In agreement with this, Northern blot analysis showed that the amounts of chiA and chiB transcripts upon induction by chitin were significantly lower in the prfA mutant than in the wild type. The chitinolytic activity and chiA and chiB expression were reduced in the absence of the sigB gene, indicating that σB is also important for the production of chitinases. The chiA, chiB, and chiA chiB mutants were not impaired for in vitro adhesion and invasion in epithelial cell lines, but the chiA chiB double mutant showed less survival ability in a chitin-enriched medium. The regulation of chitinolytic activity in L. monocytogenes is complex, and taken together, the results indicate that the biological role of this activity may not be limited to the external environment.
Vision, relationships and teacher motivation: a case study

School leaders continue to be urged to have vision. Some argue that effective schools have principals who create and communicate a vision for the school. However, although there is literature on visionary leadership, relatively little is empirical. The purpose of the study was to investigate transformational leadership behaviour and vision in schools. Four schools, in which the transformational leadership practices of principals were perceived by teachers to be characterised by individual concern and vision, were identified. A qualitative approach using semi‐structured interviews was used to collect data. Content analysis identified patterns and themes in the data from which propositions and conclusions were drawn. Within the context of the study, the results suggest that the influence of vision may be overestimated and the most critical leadership transformational behaviour is individual concern. The main conclusion of the study is that leadership in schools is mainly characterised by relationships with individuals, and it is through these relationships a leader is able to establish her/his leadership and encourage teachers to apply their expertise, abilities, and efforts towards shared purposes.
The Recall of Affirmative and Negative Sentences in an Incidental Learning Task

This experiment examined the recall of positive and negative information in an incidental learning task. The two main findings were that a significantly greater number of affirmative than negative clues were correctly recalled and that the majority of errors took the form of conversions from negative to affirmative, independently of meaning. The difficulty associated with the negative clues was explained in terms of their inappropriateness in the situation, namely in the absence of any prior expectations.

Decentralized Decision Making and Organizational Effectiveness in Colleges for Vocational Education: A Structural Equation Model for School Organization

ABSTRACT The present study deals with the effect of decentralization on organizational effectiveness in Dutch colleges for middle vocational education (or MBO in Dutch). Following recent developments in educational administration, four domains of organizational effectiveness are distinguished: adaptation; goal attainment; integration; and teachers commitment (Quinn & Rorhbaugh, 1983: Competing Values Approach). Decentralization is defined as the relative amount of influence on decision making processes at the operational level compared with strategic level. In accordance with Hanson's Interacting Spheres Model (1991) three domains of decision making are distinguished: an educational domain; an administrative domain; and a contested zone. These concepts were measured with a questionnaire which was administered to middle managers, i.e., heads of departments, course co‐ordinators, etc., within each college for vocational education in the Netherlands. From the total population, 299 middle managers (62%) of 87.
Physical Aspects of Healthy Aging: Assessments of Three Measures of Balance for Studies in Middle-Aged and Older Adults

Objectives. To investigate the reliability and correlations with age of the balance components of the EPESE, NHANES, and the Good Balance Platform System (GBPS) in a normal population of adults. Design. Cross-sectional. Setting. Urban Medical Center in the Pacific. Participants. A random sample of 203 healthy offspring of Honolulu Heart Program participants, ages 38–71. Measurements. Subjects were examined twice at visits one week apart using the balance components of the EPESE, NHANES, and the good balance system tests. Results. The EPESE and NHANES batteries of tests were not sufficiently challenging to allow successful discrimination among subjects in good health, even older subjects. The GBPS allowed objective quantitative measurements, but the test-retest correlations generally were not high. The GBPS variables correlated with age only when subjects stood on a foam pad; they also were correlated with anthropometric variables. Conclusion. Both EPESE and NHANES balance tests were too easy for healthy subjects. The GBPS had generally low reliability coefficients except for the most difficult testing condition (foam pad, eyes closed). Both height and body fat were associated with GBPS scores, necessitating adjusting for these variables if using balance as a predictor of future health.
Complete nucleotide sequence of the infectious cloned DNA components of tomato golden mosaic virus: potential coding regions and regulatory sequences

The nucleotide sequences of the infectious cloned DNA components of tomato golden mosaic virus (TGMV) have been determined. DNA A (2588 nucleotides) and DNA B (2508 nucleotides) have little sequence homology except for a region of ˜200 bases which is almost identical in the two molecules. Analysis of open reading frames revealed six potential coding regions for proteins of mol. wt. >10 000, four in DNA A and two in DNA B. Possible regulatory signals are identified and a model for bidirectional transcription of the two genome components is presented. Comparison of the nucleotide sequences of the DNAs of TGMV and cassava latent virus (CLV) revealed a fairly close relationship between TGMV DNA A and CLV DNA 1 and a comparatively distant relationship between TGMV DNA B and CLV DNA 2. All the potential coding regions in the TGMV DNAs had counterparts in the CLV DNAs suggesting an overall similarity in genome organisation, but six potential coding regions in the CLV DNAs had no counterparts in the TGMV DNAs. The 200‐base region common to the two DNAs of each virus had little sequence homology, except for a highly conserved 33‐base sequence potentially capable of forming a stable hairpin structure.
What Is Islamophobia and How Much Is There? Theorizing and Measuring an Emerging Comparative Concept

Islamophobia is an emerging comparative concept in the social sciences. Yet there is no widely accepted definition of Islamophobia that permits systematic comparative and causal analysis. This article explores how the term Islamophobia has been deployed in public and scholarly debates, emphasizing that these discussions have taken place on multiple registers. It then draws on research on concept formation, prejudice, and analogous forms of status hierarchies to offer a usable social scientific definition of Islamophobia as indiscriminate negative attitudes or emotions directed at Islam or Muslims. The article discusses the types of indicators that are most appropriate for measuring Islamophobia as well as the benefits of concept development for enabling comparative and causal analysis.
Selective J‐resolved HMBC, an efficient method for measuring heteronuclear long‐range coupling constants

An efficient pulse sequence for measuring long‐range CH coupling constants (JCH) named selective J‐resolved HMBC has been developed by replacing a 1H 180° pulse with a selective 1H 180° pulse and the HMBC pulse scheme with the constant time (CT) HMBC employed in the J‐resolved HMBC pulse sequence that we reported previously. The novel pulse sequence providing only long‐range JCH cross peaks for easy and accurate analysis enables to overcome disadvantages of the previous HMBC‐based pulse sequences (J‐resolved HMBC‐1) along with maintaining high sensitivity. The efficiency of measuring long‐range JCH using the proposed pulse sequence has been demonstrated in applications to the complicated natural products, portmicin and monazomycin.

Dominant flow extraction and analysis in traffic surveillance videos

Flow analysis of crowd and traffic videos is an important video surveillance task. In this work, we propose an algorithm for long-term flow segmentation and dominant flow extraction in traffic videos. Each flow segment is a temporal sequence of image segments indicating the motion of a vehicle in the camera view. This flow segmentation is done in the framework of Conditional Random Fields using motion and color features. We also propose a distance measure between any two flow segments based on Dynamic Time Warping and use this distance for clustering the flow segments into dominant flows. We then model each dominant flow by generating a representative flow segment, which is the mean of all the time-warped flow segments belonging to its cluster. Using these dominant flow models, we perform path prediction for the vehicles entering the view and detect anomalous motions. Experimental evaluation on a diverse set of challenging traffic videos demonstrates the effectiveness of the proposed method.
Search-based Software Requirements Selection: A Case Study

paper presents a Multi-objective Quantum-inspired Hybrid Differential Evolution (MQHDE) for the solution of software requirements selection problem and its application on a real-world project. As the customer requirements change from time to time, often software products are developed in an iterative or incremental manner so as to deal with these changing requirements. The problem is to identify a set of requirements to be included in the next release of the software product, by minimizing the cost and maximizing the customer satisfaction. This problem is referred to as Multi-objective Next Release Problem (MONRP) in the jargon of Search- based Software Engineering (SBSE). The solution to the problem of MONRP has been studied by researchers using different metaheuristic search techniques. The efficiency of the proposed MQHDE is tested on a real-world application and the results are compared against the state-of-the-art multi- objective evolutionary algorithm NSGA-II, and found that the performance of MQHDE is promising and therefore can be used with confidence for the solution of real-world instances of MONRP.
Contestation and Accommodation: Constructions of Lone Mothers’ Subjectivity Through Workfare Discourse and Practice

This article examines the ways in which dominant discourses about poor lone mothers are both contested and accommodated among three groups of actors within the workfare system in Toronto, Canada. Drawing on qualitative data from a national research project on lone mothers and social assistance, the authors examine and analyze how lone mothers construct their own subjectivity, as well as how it is constructed by workers in state-contracted nongovernmental organizations (NGOs) that deliver job-readiness and related workfare programs and by welfare workers who assess and administer welfare benefits.
