Towards Texture-Based Visualization of Multivariate Dataset

Visualization is a science which makes the invisible to visible through the techniques of experimental visualization and computer-aided visualization. This paper presents the practical aspects of visualization of multivariate dataset. In this paper, we will briefly discuss a previous research work and introduce a new visualization technique which will help us to design and develop a visualization tool for experimental visualization of multivariate dataset. Our newly developed visualization tool can be used in various domains. In this paper, we have chosen a software industry as an application domain and we used the multivariate dataset of software components computed by VizzMaintenance. VizzMaintenance is software analysis tool which give us multiple software metrics of open source Java based programs. Main objective of this research is to develop a new visualization tool for large multivariate dataset which will be more efficient and easy to perceive by viewer. Perception is very important for our research work and we have decided to test the perception level of our proposed visualization approach by researchers of our research lab.
Development of a Portable Optical Time Domain Reflectometer System in Photonic Integration Technology

In this work we present and discuss a concept of an integrated optical time domain reflectometer realized in indium phosphide generic integration technology. The proof-of-the-concept chip has been designed, manufactured and tested with respect of applicability in real measuring systems. In general, the correctness of the proposed approach has been confirmed, simultaneously indicating necessary modifications of the design. As a result, the optimized variants of the photonic integrated circuit have been proposed.
The tadpole of Rhinella proboscidea (Anura: Bufonidae) with notes on adult reproductive behavior

The tadpoles of Rhinella proboscidea are described and compared with other tadpoles of the Rhinella margaritifer group. The tadpole of R. proboscidea is characterized by small size (17.8 mm), tooth row formulae 2(2)/3, oral papillae only on lateral margins, jaw sheath V-shaped, spiracle sinistral, vent tube medial, body oval in dorsal view and depressed in lateral view, and color in life light brown. Tadpoles of R. proboscidea are morphologically similar to other species within this group and closely resemble those of R. margaritifer from Cusco Amazónico and R. castaneotica from Pará, Brazil. Rhinella proboscidea is an explosive breeder and reproduction occurs in temporary pools or small headwaters of streams or soaks, during the rainy season.
Bugine: a bug report recommendation system for Android apps

Many automated test generation tools were proposed for finding bugs in Android apps. However, a recent study revealed that developers prefer reading automated test generation cased written in natural language. We present Bugine, a new bug recommendation system that automatically selects relevant bug reports from other applications that have similar bugs. Bugine (1) searches for GitHub issues that mentioned common UI components shared between the app under test and the apps in our database, and (2) ranks the quality and relevance of issues. Our results show that Bugine could find 34 new bugs in five evaluated apps.
Parallel Implementation of DBSCAN Algorithm Based on Spark

In this project, we aim at proposing the parallel implementation of Density-based spatial clustering of applications with noise (DBSCAN) algorithm based on Spark in Python. In particular, we implemented the serial DBSCAN as local function in map stage, through proper partition methods, we can reduce results from each partition to get ﬁnal cluster labels. Additionally, as optimization strategy, distance matrix and R-Tree based optimized partition methods are imported to improve time efﬁciency achieve more balanced partition results.
Risk of infection due to central venous catheters : Effect of site of placement and catheter type

Objective To determine the influence of catheter site and type (single- vs triple-lumen) on infection rates associated with central venous catheterization. Design Prospective observational study of all nontunneled central venous catheters over a 28-month period. Data collected included patient characteristics, insertion site, catheter type, and receipt of parenteral nutrition. End points were clinical infection (bacteremia or site infection) and catheter contamination (clinical infection or colonization with >15 colonies on semiquantitative culture). Setting Medical-surgical wards of Veterans' Affairs hospital. Results Three hundred catheters were inserted into 204 patients. Seventy percent were inserted into upper-body sites, and 30% were inserted into the femoral vein. Forty-five percent were triple-lumen catheters. Bacteremia occurred in 2.7% of catheter insertions; insertion-site infections developed in 1.3%, and catheter colonization developed in 12%. Catheter contamination was associated with emergent insertion (odds ratio [OR], 6.2; 95% confidence interval [CI95], 1.1-36.7; P=.04) by logistic regression and with femoral location (hazard, 4.2; CI95, 2.0-8.8; P=.0001) and history of transplantation (hazard, 2.8; CI95, 1.1-6.7; P=.024) by Cox regression. Clinical infection was not associated with any of the risk factors evaluated, although there was a trend for association with femoral location by Cox regression (hazard, 4.7; CI95, 0.82-26; P=.08). We did not identify an association between infection and use of triple-lumen catheters or parenteral nutrition. Conclusion Our data support an association between intravenous catheter contamination and insertion at a femoral site.
Molecular Characterization of a Stress-Inducible Gene from Lactobacillus helveticus

ABSTRACT A gene (htrA) coding for a stress-inducible HtrA-like protein from Lactobacillus helveticus CNRZ32 was cloned, sequenced, and characterized. The deduced amino acid sequence of the gene exhibited 30% identity with the HtrA protein fromEscherichia coli; the putative catalytic triad and a PDZ domain that characterize the HtrA family of known bacterial serine proteases were also found in the sequence. Expression of the L. helveticus htrA gene in a variety of stress conditions was analyzed at the transcriptional level. The strongest induction, resulting in over an eightfold increase in the htrAtranscription level, was found in growing CNRZ32 cells exposed to 4% (wt/vol) NaCl. Enhanced htrA mRNA expression was also seen in CNRZ32 cells after exposure to puromycin, ethanol, or heat. The reporter gene gusA was integrated in theLactobacillus chromosome downstream of the htrApromoter by a double-crossover event which also interrupted the wild-type gene. The expression of gusA in the stress conditions tested was similar to that of htrA itself. In addition, the presence of an intact htrA gene facilitated growth under heat stress but not under salt stress.
Influence of vascular plant photosynthetic rate on CH4 emission from peat monoliths from southern boreal Sweden

Peat monoliths taken from a boreal peatland system were incubated at two different light intensities to investigate the effect of the photosynthetic rate of vascular plants (Eriophorum angustifolium) on net CH4 emission. The experimental set-up consisted of six replicate monoliths as controls and six where the photosynthetic active radiation (PAR) was reduced by 60%. NEP and total system respiration decreased significantly in response to reduced PAR. No significant changes in CH4 emission were found, but two different trends were noted. Methane emissions from the shaded monoliths initially seemed to be higher than emissions from the controls. After approximately four weeks the trend was reversed. The pattern may have been caused by “leakage” of organic compounds from inactivated roots that fueled CH4 production. It is suggested that a new balanced exchange of potential substrate carbon between the plants and the surrounding peat was established. Comparably less easily degradable carbon compounds would then become available for CH4 production. The fact that there appeared to be an effect of decreased carbon flow on CH4 emission is further supported by a tendency for lower concentrations of organic acids in porewater in the shaded monoliths at the end of the experiment. These results indicate a possible lagtime on the order of weeks before changes in photosynthesis rates and NEP have an effect onCH4 emission rates. Nevertheless it confirms the linkage between CO2 and CH4 cycling in wetland ecosystems.
The Highly Conserved, Coregulated SNO andSNZ Gene Families in Saccharomyces cerevisiaeRespond to Nutrient Limitation

SNZ1, a member of a highly conserved gene family, was first identified through studies of proteins synthesized in stationary-phase yeast cells. There are three SNZ genes in Saccharomyces cerevisiae, each of which has another highly conserved gene, named SNO (SNZ proximal open reading frame), upstream. The DNA sequences and relative positions of SNZ and SNO genes have been phylogenetically conserved. This report details studies of the expression of the SNZ-SNO gene pairs under various conditions and phenotypic analysis of snz-sno mutants. An analysis of total RNA was used to determine that adjacent SNZ-SNO gene pairs are coregulated. SNZ2/3 and SNO2/3 mRNAs are induced prior to the diauxic shift and decrease in abundance during the postdiauxic phase, when SNZ1 and SNO1 are induced. In snz2 snz3 mutants, SNZ1 mRNA is induced prior to the diauxic shift, when SNZ2/3 mRNAs are normally induced. Under nitrogen-limiting conditions, SNZ1 mRNAs accumulate in tryptophan, adenine, and uracil auxotrophs but not in prototrophic strains, indicating that induction occurs in response to the limitation of specific nutrients. Strains carrying deletions in all SNZ-SNO gene pairs are viable, but snz1 and sno1 mutants are sensitive to 6-azauracil (6-AU), an inhibitor of purine and pyrimidine biosynthetic enzymes, and methylene blue, a producer of singlet oxygen. The conservation of sequence and chromosomal position, the coregulation and pattern of expression of SNZ1 and SNO1 genes, and the sensitivity of snz1 and sno1 mutants to 6-AU support the hypothesis that the associated proteins are part of an ancient response to nutrient limitation.
Type III and Type IV Endoleak: Toward a Complete Definition of Blood Flow in the Sac after Endoluminal AAA Repair

In this document the authors continue to refine their seminal categorization of endoleak, a major complication of endovascular aneurysm repair. In addition to type I (related to the graft device itself) and type II (retrograde flow from collateral branches) endoleak, they propose two new categories: endoleak due to fabric tears, graft disconnection, or disintegration would be classified type III, and flow through the graft presumed to be associated with graft wall “porosity” would be categorized as type IV endoleak.
Viral Aerosol Concentration Characterization and Detection in Bounded Environments

Viral spread has been intermittently threatening human life over time. Characterizing the viral concentration and modelling the viral transmission are, therefore, considered major milestones for enhancing viral detection capabilities. This paper addresses the problem of viral aerosol detection from the exhaled breath in a bounded environment, e.g., a bounded room. The paper models the exhaled breath as a cloud which is emitted through the room, and analyzes the temporal-spatial virus-laden aerosol concentration by accounting for partial absorption and reflection at each side of the room. The paper first derives a closed form expression of the temporal-spatial virus-laden aerosol concentration. It then considers the deployment of a receiver composed of an air sampler and a bio-sensor to detect the viral existence of a specific virus. We, therefore, assess the detection capabilities of the proposed system via evaluating the viral miss-detection probability as a function of the sampling volume and the detection time-instance at the receiver side. Our numerical simulations verify the validity of the analytical results, and illustrate the ability of the proposed system to detect viruses in indoor environments. The results further characterize the impacts of several system parameters on the miss-detection probability.
Gene expression of components of the insulin/insulin-like signaling pathway in response to heat stress in the garter snake, Thamnophis elegans

The insulin/insulin-like signaling (IIS) pathway is an evolutionary conserved molecular signaling pathway that regulates growth, reproduction, stress resistance, and longevity in response to nutrition and external stress. While the constituents of this pathway and their functions are relatively well understood in laboratory model animals, they have not been explored in many other organisms, with notable exceptions in the fisheries literature. We tested for the gene expression of four key components of this pathway in the garter snake (Thamnophis elegans) liver, and determine how the transcription of these components responds to heat stress. We found that the two insulin-like growth factor ligands (IGF-1 and IGF-2) and the receptors (IGF-1 Receptor and M6P/IGF-2 Receptor, or IGF-1R and IGF-2R) are expressed in garter snake liver tissue. Under normal laboratory conditions, IGF-2 and IGF-2R are expressed at a higher level than IGF-1 and IGF-1R. In response to heat stress, IGF-1 expression remained the same, .
Managing New Product Definition in Highly Dynamic Environments

In highly dynamic environments, characterized by changing customer preferences and uncertainty about competitive products, managing the development of a new product is a complex managerial task. The traditional practice, recommended in the literature, of reaching a sharp definition early in the new product development (NPD) process may not be optimal, desirable or even feasible in such dynamic situations. Under high uncertainty, forcing early finalization of specifications may result in a firm getting locked into an incorrect definition. Based on our study of NPD in the high technology industry, we present a model of an approach called real-time definition, in which a firm adapts its product definition process to the market and competitive environment. Uncertainty in the product definition is resolved through frequent, repeated interactions with customers and using a flexible development process. We find that early definition is optimal only in a limited set of situations. To maximize its anticipated profits, a firm should tune its definition process to the prevailing level of market uncertainty, the marginal value of information obtained from the customer during the NPD process, and its own risk-profile and internal development capabilities. Effects of competition on a firm's definition approach are also examined, and implications for managers of a NPD process are presented using a conceptual framework.

Teasing in Hierarchical and Intimate Relations

Following E. Goffman's( 1967) face threat analysis of social interaction, it was hypothesized that the aggressive, playful content of teasing would vary according to social status and relational satisfaction, personality, role as teaser or target, and gender. These 4 hypotheses were tested in analyses of the teasing among fraternity members (Study 1) and romantic couples (Study 2). Consistent with a face threat analysis of teasing, low-status fraternity members and satisfied romantic partners teased in more prosocial ways, defined by reduced face threat and increased redressive action. Some findings indicate that disagreeable individuals teased in less prosocial ways, consistent with studies of bullying. Targets reported more negative emotion than teasers. Although female and male romantic partners teased each other in similar ways, women found being the target of teasing more aversive, consistent with previous speculation. The joke, in other words, is the art of making fun without raising anger, by means of ritual mockery of insults which are neutralized by their very excess and which, presupposing a great familiarity . are in fact tokens of attention or affection, ways of building up while seeming to run down, of accepting while seeming to
Pupils’ Attitudes to Science in Key Stage 3 of the National Curriculum: a study of pupils in South Wales

This paper describes part of a continuing research project based at the University of Wales, Swansea, which is investigating pupils' attitudes to a range of national curriculum subjects. There has been no major national funded project to evaluate the national curriculum from pupils' perspectives. The market economy philosophy adopted by the present government is restricted in the meaning of choice given to consumers of education. Pupils' opinions are rarely sought out.
Analysis of cell wall synthesis genes in feeding cells formed by root -knot nematodes

HUDSON, LAURA C. Analysis of Cell Wall Synthesis Genes in Feeding Cells Formed by Root-Knot Nematodes. (Under the direction of Eric Davis). Root-knot nematodes (Meloidogyne sp.) are sedentary endoparasites that infect roots of a wide range of plant species and cause considerable economic loss to many crops. Rootknot nematodes (RKN) transform selected root vascular cells into enlarged, multinucleate feeding sites called giant-cells that arise from repeated karyokinesis without cytokinesis. Giant-cells undergo extensive modifications of the cell wall architecture including cell wall thickening and the formation of ingrowths that act to increase the surface area of the plasma membrane to facilitate solute uptake by the nematode. Extensive cell division is stimulated around the giant-cells to give rise to the root gall that is characteristic of RKN infection. Extensive cell wall modifications taking place in feeding cells are hypothesized to be mediated by both cell wall-loosening and cell wall biosynthetic enzymes of plant origin based on evidence that nematodes alter gene expression in plants during formation of feeding cells. Ten members of the cellulose synthase (CesA) gene family of Arabidopsis thaliana were analyzed to monitor cell wall deposition in RKN infection sites. CesA gene promoter::GUS constructs and developmental quantitative RT-PCR indicated that CesA genes responsible for both primary and secondary cell wall synthesis were temporally and quantitatively expressed in the same pattern, with peak activity in RKN infection sites at five days post-inoculation. Sections of RKN infection sites in CesA promoter::GUS roots indicated that upregulated secondary cell wall CesA genes were localized within the central giant-cells and primary cell wall CesA genes were primarily localized to the surrounding dividing cells (gall tissue) of the infection site. The number of galls and RKN female development were decreased in Arabidopsis mutants in eight of the CesA genes, and complementation studies with the constitutive 35S promoter restored the mutant phenotypes of CESA4, CESA5, and CESA7 (involved in secondary cell wall synthesis) and also restored normal RKN infection levels. Mutant complementation of the CESA4, CESA5, and CESA7 genes with the giant-cell-inducible NtCel7 promoter had limited effects on mutant plant phenotype and RKN infection rates, but the development of successful infective RKN females was increased dramatically. The combined data support a critical role for plant CESA gene activity working in consort to generate the proper root morphology to promote nematode infection and for the development of feeding cells to support nematode growth and reproduction.

Comparison of Air and Ground Deer Counts in Colorado

Since the aerial technique is an important tool of big-game management in Colorado, a study was instigated in 1953, with specific objectives as follows: (1) to determine the ratio between aerial and ground counts of mule deer (Odocoileus hemionus hemionus) on a given area; (2) to determine the variation in this ratio between replications, pilots, observers, cover types, and snow conditions; (3) to evolve factors that will correct aerial counts to give ground totals for a given cover type and given counting conditions; and (4) to determine the limiting factors of aerial counts and how these counts may be used to gather population information from permanently established "trend
Mesoscopic continuum mechanics applied to liquid crystals

Continuum mechanics is based on the balance equations of mass, momentum, angular momentum or spin, total or kinetic energy and internal energy. Additionally, one has to consider the balance of entropy for taking into account the second law. In non-relativistic physics, all these balances are defined on time and position (x, t). Beyond the quantities whose balance equations are mentioned above, complex materials need more variables for their unique description. Examples for these additional quantities are internal variables, order and damage parameters, Cosserat triads, directors and alignment and conformation tensors.
