System development for research map visualisation

Finding a research gap is an important and difficult step in the research world. To find the research problem, one needs to read and analyze a lot of scientific articles. Although many systems and methods have been develop to assist the above process such as bibliographic analysis & visualization as well as scientific articles recommendation systems, almost all of them are limited to find relevant articles. A tool that helps researchers to get a bigger picture of research in a topic of interests is very desirable. This paper reports our effort in the development of research map visualizers, which we believe will be a useful tool for researchers. Assuming that the detail information about articles is available, the system can visualize a research map according to the user information needs. The user can specify the visualization parameters to explore the various ways of presenting a research map. The visualization parameters include selecting the information along ordinate and abscissa as well as the type of relation among articles. The system has been designed by considering usability and user experience goals. The usability testing for the system that has been conducted reveals that it can attain the goals of effectiveness, learnability, satisfying, being helpful and fun.
The role of the palate in tongue kinematics: an experimental assessment in v sequences from EPG and EMMA data

The effect of palatal contact on tongue tip kinematics was investigated using simultaneous EMMA and EPG recordings. The material consisted of VC sequences, where C is a voiced or voiceless alveolar stop. The kinematic characteristics were studied by analyzing parameters of the velocity profile and the deceleration peaks of the closing gesture. No evidence could be found for a potential influence of lateral contacts. Central contacts, associated with the beginning of the consonantal closure, are strongly correlated in time with the velocity drop. It supports the hypothesis that for achieving a consonantal closure tongue tip kinematics is not controlled by a specific target on the palate, and that its deceleration phase is mostly influenced by the collision with the palate.
HUMAN COCHLEAR MODEL : A SIMULINK IMPLEMENTATION

Models of human auditory pathway are commonly used as a part of audio coding systems or algorithms for objective evaluation of sound quality. In order to simulate properly the nonlinear, signal-dependent behavior of the cochlea, physiologically accurate models are being developed. In the paper, a SIMULINK implementation of a hardware active nonlinear model of human cochlea is presented. The model was designed to reproduce satisfactorily the masking properties, frequency selectivity and sensitivity of human inner ear.
Immune response to Fusobacterium nucleatum, Prevotella intermedia and other anaerobes in children with acute tonsillitis.

The number of aerobic and anaerobic bacteria was determined in the saliva of 20 children with acute group A beta-haemolytic streptococcal (GABHS) pharyngo-tonsillitis, and 20 with acute non-GABHS tonsillitis. Antibody titres to four Gram-negative anaerobic bacilli that reside in the oropharynx (Fusobacterium nucleatum, Prevotella intermedia, Porphyromonas gingivalis, and Actinobacillus actinomycetemcomitans) were determined in these and 20 control patients. An average of 8.8 aerobic and anaerobic isolates per patient saliva specimens were found during the acute tonsillitis stage in both groups, and 6.9 (in GABHS tonsillitis) and 5.6 (in non-GABHS tonsillitis) 5-6 weeks later. There were 10- to 1000-fold more bacteria in the acute stages of the inflammation in both GABHS and non-GABHS groups. These bacteria were Staphylococcus aureus, Haemophilus influenzae, Moraxella catarrhalis, Peptostreptococcus spp. , F. nucleatum, Prevotella spp. and Porphyromonas spp. Significantly higher antibodies levels to F. nucleatum and P. intermedia were found in the second serum sample of patients with non-GABHS pharyngo-tonsillitis (P < 0.001) and GABHS tonsillitis (P < 0.05), as compared with their first sample or the levels of antibodies in controls. The increase in the number of several aerobic and anaerobic bacteria during acute tonsillitis and the increase in antibody levels to F. nucleatum and P. intermedia, known oral pathogens, may suggest a possible pathogenic role for these organisms in acute non-GABHS and GABHS tonsillitis.
Temperature dependence of biomolecular circuit designs

Quantifying performance of biomolecular circuit designs across different environmental conditions is a key step in assessing their robustness. It is generally unclear how robust this performance is to the important environmental variable of temperature. Here, we address this issue for a transcriptional negative feedback circuit design that can speed up the response time using a combination of simple computational methods and dynamic experimental measurements. We use a simple two-state model of gene expression to illustrate different ways in which temperature dependence of reaction rate parameters can propagate through to the functional output. Next, we extend this analysis to the response time of a transcriptional negative feedback circuit design. Finally, we present experimental results estimating how response time of a negative transcriptional feedback circuit depends on temperature. These results help to develop a framework for assessing how functional output of biomolecular circuit designs can depend on temperature.
Parallelization of loops with exits on pipelined architectures

Modulo scheduling theory can be applied successfully to overlap Fortran DO loops on pipelined computers issuing multiple operations per cycle both with and without special loop architectural support. It is shown that a broader class of loops-repeat-until, while, and loops with more than one exit-where the trip count is not known beforehand, can also be overlapped efficiently on multiple issue pipelined machines. Special features that are required in the architecture as well as compiler representations for accelerating these loop constructions are discussed. The approach uses hardware architectural support, program transformation techniques, performance bounds calculations, and scheduling heuristics. Performance results are presented for a few select examples. A prototype scheduler is currently under construction for the Cydra 5 directed dataflow computer. <<ETX>>
ODrM* optimal multirobot path planning in low dimensional search spaces

We believe the core of handling the complexity of coordinated multiagent search lies in identifying which subsets of robots can be safely decoupled, and hence planned for in a lower dimensional space. Our work, as well as those of others take that perspective. In our prior work, we introduced an approach called subdimensional expansion for constructing low-dimensional but sufficient search spaces for multirobot path planning, and an implementation for graph search called M*. Subdimensional expansion dynamically increases the dimensionality of the search space in regions featuring significant robot-robot interactions. In this paper, we integrate M* with Meta-Agent Constraint-Based Search (MA-CBS), a planning framework that seeks to couple repeatedly colliding robots allowing for other robots to be planned in low-dimensional search space. M* is also integrated with operator decomposition (OD), an A*-variant performing lazy search of the outneighbors of a given vertex. We show that the combined algorithm demonstrates state of the art performance.
LP-GALS-C: a new low-power globally asynchronous locally synchronous architecture for symmetric-key cryptography

Internet security protocols are commonly used to provide secure connectivity over public insecure networks. Encrypting traffic, authentication and validating packets' integrity are all services provided by network security. These services implement symmetric-key cryptographic algorithms. Architectures that implement network security not only have to meet high computing demands, but they also have to be flexible enough to adapt to changing cryptographic parameters and to respond to changes in security standards. Mobile and secure communication are likely to be key building blocks of the future communication environment. This sets another burden on cryptographic architectures to be power efficient. In this paper we study some of the prominent cryptographic architectures. This study led to the development of a new architecture for Low-Power Globally Asynchronous Locally Synchronous processor for Cryptography (LP-GALS-C). We provide a detailed discussion of the top level architecture and some of the composing elements. We also show the advantages of LP-GALS-C over existing architectures and the micro-architectural solutions employed to reduce power requirements.
A tunable compression framework for bitmap indices

Bitmap indices are widely used for large read-only repositories in data warehouses and scientific databases. Their binary representation allows for the use of bitwise operations and specialized run-length compression techniques. Due to a trade-off between compression and query efficiency, bitmap compression schemes are aligned using a fixed encoding length size (typically the word length) to avoid explicit decompression during query time. In general, smaller encoding lengths provide better compression, but require more decoding during query execution. However, when the difference in size is considerable, it is possible for smaller encodings to also provide better execution time. We posit that a tailored encoding length for each bit vector will provide better performance than a one-size-fits-all approach. We present a framework that optimizes compression and query efficiency by allowing bitmaps to be compressed using variable encoding lengths while still maintaining alignment to avoid explicit decompression. Efficient algorithms are introduced to process queries over bitmaps compressed using different encoding lengths. An input parameter controls the aggressiveness of the compression providing the user with the ability to tune the tradeoff between space and query time. Our empirical study shows this approach achieves significant improvements in terms of both query time and compression ratio for synthetic and real data sets. Compared to 32-bit WAH, VAL-WAH produces up to 1.8× smaller bitmaps and achieves query times that are 30% faster.
First stars and the extragalactic background light: how recent $\gamma$-ray observations constrain the early universe

Context. The formation of the first stars (Population III; PopIII) marks the end of the dark ages of the universe, a subject of lively scientific debate. Not (yet) accessible to direct observations, this early stage of the universe is mostly studied via theoretical calculations and numerical simulations. An indirect window is provided by integrated present day observables such as the metal abundance or the diffuse extragalactic photon fields. Aims. We aim to derive constraints on the properties of the PopIII and low metallicity Population II (LM PopII) stars utilizing limits on the density of the extragalactic background light (EBL), recently derived from very-high-energy (E > 100 GeV; VHE) observations. Methods. A model calculation for the evolving EBL density produced by PopIII/LM PopII stars is presented. The model utilizes stellar population spectra (SPS) for zero and low metallicity stars and accounts for the changing emission of an aging stellar population. Emission from the dense HII regions surrounding the stars (nebula) is included. The resulting EBL density for different scenarios (metallicity, star formation rate, initial mass function) is compared to the limit on the EBL density. The potential for detecting a cut-off in HE/VHE spectra is discussed. Results. Assuming a maximum contribution from PopIII/LM PopII stars to the EBL density of 5 nW m −2 s −1 at 2 μm, a limit on the
DiFX: A Software Correlator for Very Long Baseline Interferometry Using Multiprocessor Computing Environments

We describe the development of an FX‐style correlator for very long baseline interferometry (VLBI), implemented in software and intended to run in multiprocessor computing environments, such as large clusters of commodity machines (Beowulf clusters) or computers specifically designed for high‐performance computing, such as multiprocessor shared‐memory machines. We outline the scientific and practical benefits for VLBI correlation, these chiefly being due to the inherent flexibility of software and the fact that the highly parallel and scalable nature of the correlation task is well suited to a multiprocessor computing environment. We suggest scientific applications where such an approach to VLBI correlation is most suited and will give the best returns. We report detailed results from the Distributed FX (DiFX) software correlator running on the Swinburne supercomputer (a Beowulf cluster of ∼300 commodity processors), including measures of the performance of the system. For example, to correlate all Stokes products for a 10 antenna array with an aggregate bandwidth of 64 MHz per station, and using typical time and frequency resolution, currently requires an order of 100 desktop‐class compute nodes. Due to the effect of Moore’s law on commodity computing performance, the total number and cost of compute nodes required to meet a given correlation task continues to decrease rapidly with time. We show detailed comparisons between DiFX and two existing hardware‐based correlators: the Australian Long Baseline Array S2 correlator and the NRAO Very Long Baseline Array correlator. In both cases, excellent agreement was found between the correlators. Finally, we describe plans for the future operation of DiFX on the Swinburne supercomputer for both astrophysical and geodetic science.
Grasp Frequency and Usage in Daily Household and Machine Shop Tasks

In this paper, we present results from a study of prehensile human hand use during the daily work activities of four subjects: two housekeepers and two machinists. Subjects wore a head-mounted camera that recorded their hand usage during their daily work activities in their typical place of work. For each subject, 7.45 hours of video was analyzed, recording the type of grasp being used and its duration. From this data, we extracted overall grasp frequency, duration distributions for each grasp, and common transitions between grasps. The results show that for 80 percent of the study duration the housekeepers used just five grasps and the machinists used 10. The grasping patterns for the different subjects were compared, and the overall top 10 grasps are discussed in detail. The results of this study not only lend insight into how people use their hands during daily tasks, but can also inform the design of effective robotic and prosthetic hands.

The purpose of this descriptive study was to investigate preschool teachers’ use of strategies to support young children’s social-emotional competence. A total of 103 teachers and classrooms participated in the study. Descriptive findings of the study indicated that preschool teachers implemented a few practices to promote social-emotional competence in young children in the absence of training and professional development support. Preschool teachers were observed to implement universal promotion practices more often than tertiary preventions practices. Preschool teachers’ overall use of strategies to enhance the social-emotional competence of young children did not differ significantly across classroom types and levels and based on whether teachers received training on promoting social-emotional development and addressing challenging behaviors. Moreover, positive correlations between the level of preschool teachers’ use of social-emotional teaching strategies, classroom quality scores, and the number of adults in each classroom were observed. It was also observed that the correlation between preschool teachers’ use of strategies and the number of children in each classroom was negative. Implications of the findings for future research and practice are discussed.
The complete mitochondrial genomes of Dactylellina Leptospora (Orbiliales, Orbiliaceae)

Abstract In this study, the complete mitochondrial DNA sequence was obtained from Dactylellina leptospora using next-generation sequencing technology. The mitogenome is a circular molecule of 201,677 bp in length. The overall nucleotide composition was 38.54% A, 36.34% T, 11.21% C, and 13.9% G, with a higher A + T content (74.88%) than other species. In the D. leptospora mitogenome, we identified 36 genes including 15 protein-coding genes, 2 ribosomal RNA (rRNA), 19 transfer RNA (tRNA). Phylogenetic analysis showed D. leptospora was genetically divergent from species Pyronema omphalodes within Pezizomycetes.
Evidence on Informal Insurance in Rural Zimbabwe

The test for the presence of full insurance employed by Townsend [Econometrica, 63(3), 539--91, 1994] and various others does not take into account that households rely on buffer stocks to shield their consumption from income shocks. In this paper it is shown how, in the presence of partial insurance, not including buffer stocks leads to estimates that underreport the degree of informal insurance. A test to correct for this omission is developed and is applied to panel data from rural Zimbabwe. Copyright 2002, Oxford University Press.
Dyadic Analysis of Childhood Emotional Maltreatment and Marital Satisfaction During the Transition to Parenthood: The Mediating Effects of Emotion Regulation Strategies and Psychological Distress

ABSTRACT Childhood emotional maltreatment (CEM) has been found to be associated with marital dissatisfaction. However, less attention has been paid to the married couples during the initial transition to parenthood from the perspective of both partners, as well as the underlying mechanisms by which parents’ CEM histories are related to marital satisfaction. The purposes of this study were to examine the relation between CEM and current marital satisfaction among first-time parents using dyadic analysis, and to test the serial mediating effects of emotion regulation strategies and psychological distress. A total of 156 couples during the transition to parenthood from mainland China reported on CEM, emotion regulation strategies (i.e., cognitive reappraisal and expressive suppression), psychological distress (i.e., depression, anxiety, and stress symptoms), and marital satisfaction at 6 months postpartum. Results indicated that paternal depression significantly mediated the paths from paternal emotional maltreatment to paternal and maternal marital dissatisfaction. In comparison, maternal depression significantly mediated the link between maternal CEM and maternal marital dissatisfaction. In addition, the association between maternal CEM and maternal marital satisfaction was serially mediated by maternal cognitive reappraisal and maternal depression. This study highlights the importance of examining the link between CEM and marital satisfaction and its underlying mechanisms from the dyadic perspective.
Monte Carlo simulation of distributed rainfall-runoff conditions for probabilistic short-term flood forecasting

A framework for short-term probabilistic forecasting of watershed flood stage conditions using a distributed rainfall-runoff model is proposed. A stochastic rainfall pattern simulation model capable of generating input for a distributed rainfall-runoff model is developed. Generation of rainfall patterns over a 6-hour period is achieved using a translation vector rainfall forecasting process modified to account for uncertainties in rainfall pattern development. The stochastic rainfall generation model is coupled with a distributed rainfall-runoff model in a Monte-Carlo simulation to provide a short-term ensemble forecast of distributed flood discharge. An adaptive updating procedure for the real-time reduction of forecast error suitable for use with a distributed rainfall-runoff model is developed for the system. An example application of the proposed probabilistic flood stage forecasting system is provided for a typhoon event that occurred in the vicinity of the Nagara River watershed located in Gifu, Japan.
Identification of Sox17 as a Transcription Factor That Regulates Oligodendrocyte Development

Microarray analysis of oligodendrocyte lineage cells purified by fluorescence-activated cell sorting (FACS) from 2′,3′-cyclic nucleotide 3′-phosphodiesterase (CNP)–enhanced green fluorescent protein (EGFP) transgenic mice revealed Sox17 (SRY-box containing gene 17) gene expression to be coordinately regulated with that of four myelin genes during postnatal development. In CNP–EGFP-positive (CNP–EGFP+) cells, Sox17 mRNA and protein levels transiently increased between postnatal days 2 and 15, with white matter O4+ preoligodendrocytes expressing greater Sox17 levels than Nkx2.2+ (NK2 transcription factor related, locus 2) NG2+, or GalC+ (galactocerebroside) cells. In spinal cord, Sox17 protein expression was undetectable in the primary motor neuron domain between embryonic days 12.5 and 15.5 but was evident in Nkx2.2+ and CC1+ cells. In cultured oligodendrocyte progenitor cells (OPCs), Sox17 levels were maximal in O4+ cells and peaked during the phenotypic conversion from bipolar to multipolar. Parallel increases in Sox17 and p27 occurred before MBP protein expression, and Sox17 upregulation was prevented by conditions inhibiting differentiation. Sox17 downregulation with small interfering RNAs increased OPC proliferation and decreased lineage progression after mitogen withdrawal, whereas Sox17 overexpression in the presence of mitogen had opposite effects. Sox17 overexpression enhanced myelin gene expression in OPCs and directly stimulated MBP gene promoter activity. These findings support important roles for Sox17 in controlling both oligodendrocyte progenitor cell cycle exit and differentiation.
Reconceptualizing uncertainty in illness: commonalities, variations, and the multidimensional nature of uncertainty

ABSTRACT Communication scholars have been long interested in uncertainty and its connection to communicative actions. Since the special issue of Journal of Communication on uncertainty and communication [Babrow, (2001a). Introduction to the special issue on uncertainty, evaluation, and communication. Journal of Communication, 51, 453–455. doi:10.1111/j.1460-2466.2001. tb02890.x], there is growing literature, including both theoretical advancements and empirical investigations, in this area of research, especially in health communication contexts. However, substantial variation exists in how uncertainty is defined across different research traditions, with a heavy yet narrow emphasis on probability and information deficit perspective. This paper reviews and synthesizes conceptualizations and operationalizations of uncertainty and highlights its multidimensional nature. Given that uncertainty and uncertainty management is context-specific, this paper focuses primarily on illness uncertainty. Theoretical and practical implications for understanding uncertainty and uncertainty management are discussed.
