Effects of electron beam irradiation on charpy impact value of GFRP

Glass fiber reinforced polymers GFRPs are increasingly being applied as structural materials with their advantages of light weight and high strength in the fields of aerospace engineering and rapid transport engineering. To strengthen the GFRPs, sheet electron beam (EB) irradiation under low potential has been performed homogeneously. Effects of EB-irradiation on Charpy impact value of GFRPs have been studied. The irradiation, applied as a short-time treatment at room temperature, enhances the impact value of GFRPs at every fracture probability. The effect of EB-irradiation on the impact value of GFRPs mainly depends on the ductility enhancement of the GFRPs. EB-irradiation also enhances the reliability indicated by the minimum impact value (a s ), as well as the Weibull coefficient.
An architecture for semantic service discovery and realizability in cloud computing

One of the open issues in cloud computing is service discovery. Another issue, which has received less attention by practitioners in the cloud computing industry, is service composition based on formal methods, particularly those based on automata and formal languages. In recent years, semantic techniques and cloud ontology have been used to improve the process of finding similar services in the cloud environment. Cloudle, which is the most recent agent-based and semantic-supported search engine in cloud systems, exploits such techniques. Though many models and architectures have been proposed to develop Cloudle, none of them used formal methods for composing services. In this paper, behavior composition, as a formal approach and a sound and complete controller synthesis technique, is adapted to provide a formal approach for resource matching and service composition.
A Programming Language to Facilitate the Transition from Rapid Prototyping to Efficient Software Production

Dynamic languages are becoming increasingly popular for developing different kinds of applications, being rapid prototyping one of the scenarios where they are widely used. The dynamism offered by dynamic languages is, however, counteracted by two main limitations: no early type error detection and fewer opportunities for compiler optimizations. To obtain the benefits of both dynamically and statically typed languages, we have designed theStaDynprogramming language to provide both approaches. Our language implementation keeps gathering type information at compile time, even when dynamic references are used. This type information is used to offer compile-time type error detection, direct interoperation between static and dynamic code, and better runtime performance. Following the Separation of Concerns principle, dynamically typed references can be easily turned into statically typed ones without changing the application source code, facilitating the transition from rapid prototyping to efficient software production. This paper describes the key techniques used in the implementation of StaDynto obtain these benefits.
A fast, interactive 3D paper-flier metaphor for digital bulletin boards

We describe a novel interface for presenting interactive content on public digital bulletin boards. Inspired by paper fliers on physical bulletin boards, posted content is displayed using 3D virtual fliers attached to a virtual corkboard by virtual pushpins. Fliers appear in different orientations, creating an attractive, informal look, and have autonomous behaviors like fluttering in the wind. Passersby can rotate, move and fold fliers; they can also interact with fliers’ live content. Flier content is streamed from a server and represented by the system on large screen displays using a real-time cloth simulation algorithm. We describe our prototype, and offer the results of an initial evaluative user study.
Modeling XCS in class imbalances: population size and parameter settings

This paper analyzes the scalability of the population size required in XCS to maintain nichesthat are infrequently activated.Facetwise models have been developed to predict the effect of the imbalance ratio--ratio betweenthe number of instances of the majority class and the minority class that are sampled to XCS--on population initialization, andon the creation and deletion of classifiers of the minority class. While theoretical models show that, ideally, XCS scales linearly with the imbalance ratio, XCS with standard configuration scales exponentially. The causes that are potentially responsible for this deviation from the ideal scalability are also investigated. Specifically, the inheritance procedure of classifiers' parameters, mutation, and subsumption are analyzed, and improvements in XCS's mechanisms are proposed to effectively and efficiently handle imbalanced problems. Once the recommendations are incorporated to XCS, empirical results show that the population size in XCS indeed scales linearly with the imbalance ratio.
Enabling high-level network programming: A northbound API for Software-Defined Networks

Software-Defined Networking (SDN) is a new paradigm that is attracting significant attention from both academy and industry. In recent years, increasing research efforts have addressed the conception of programming interfaces—northbound APIs—which allow business-applications to properly communicate with SDN controllers and program the network. However, most of current SDN controllers still offer low-level northbound interfaces based on the OpenFlow protocol, which incurs an undesirable but common coupling between network application and controller's code. As software developers often have to insert intricate controller-specific instructions directly into the application's code, this dramatically impairs its reusability and maintainability. In this paper, we propose an open northbound API that enables streaming video applications to easily enforce Quality of Service (QoS) requirements in a high-level fashion, without incurring any controller's code coupling or network operator intervention. The results of a statistical analysis show that our solution can increase the average bandwidth rate in comparison to traditional command-line-driven management approaches. In particular, a simulation study is conducted on a single-controlled SDN architecture using Floodlight controller, where our northbound API performs well, meeting quality of service requirements at runtime with a high statistical confidence.

Web services-based text-mining demonstrates broad impacts for interoperability and process simplification

The Critical Assessment of Information Extraction systems in Biology (BioCreAtIvE) challenge evaluation tasks collectively represent a community-wide effort to evaluate a variety of text-mining and information extraction systems applied to the biological domain. The BioCreative IV Workshop included five independent subject areas, including Track 3, which focused on named-entity recognition (NER) for the Comparative Toxicogenomics Database (CTD; http://ctdbase.org). Previously, CTD had organized document ranking and NER-related tasks for the BioCreative Workshop 2012; a key finding of that effort was that interoperability and integration complexity were major impediments to the direct application of the systems to CTD's text-mining pipeline. This underscored a prevailing problem with software integration efforts. Major interoperability-related issues included lack of process modularity, operating system incompatibility, tool configuration complexity and lack of standardization of high-level inter-process communications. One approach to potentially mitigate interoperability and general integration issues is the use of Web services to abstract implementation details; rather than integrating NER tools directly, HTTP-based calls from CTD's asynchronous, batch-oriented text-mining pipeline could be made to remote NER Web services for recognition of specific biological terms using BioC (an emerging family of XML formats) for inter-process communications. To test this concept, participating groups developed Representational State Transfer /BioC-compliant Web services tailored to CTD's NER requirements. Participants were provided with a comprehensive set of training materials. CTD evaluated results obtained from the remote Web service-based URLs against a test data set of 510 manually curated scientific articles. Twelve groups participated in the challenge. Recall, precision, balanced F-scores and response times were calculated. Top balanced F-scores for gene, chemical and disease NER were 61, 74 and 51%, respectively. Response times ranged from fractions-of-a-second to over a minute per article. We present a description of the challenge and summary of results, demonstrating how curation groups can effectively use interoperable NER technologies to simplify text-mining pipeline implementation.

Early impaired β-cell function in chinese women with polycystic ovary syndrome.

BACKGROUND The pathogenic factors that account for the development of diabetes condition in Chinese women with polycystic ovary syndrome (PCOS) remain elusive. AIM To clarify the pathogenic features by evaluating the levels of insulin sensitivity and β cell function in these women with PCOS, either separately or by using of a disposition indexes (DIs). METHODS Cross-sectional study involving 137 Chinese women with PCOS and 123 normal women were examined by anthropometry, lipid profile, sex hormone, high-sensitivity C reactive protein, oral glucose tolerance tests and insulin tolerance tests. RESULTS After controlling for BMI status, the Matsuda Index was significantly lower in women with PCOS in comparison to those of normal women (p<0.000). The early phase of insulin secretion (insulinogenic index) remained significantly lower in lean women with PCOS(LP) than those of both lean and obese women of control group (p=0.007, and p = 0.01, respectively). The mean HOMA-F values were significantly lower (p =0.045) in obese women with PCOS (OP) than those of BMI-matched women. Further, all DIs derived from non-fasting state indexes in women with PCOS were significantly lower than those of BMI-matched control women (p<0.001 for all). Lastly, DIs derived from fasting states indexes in OP were significantly lower than those of LP. CONCLUSION Early impaired β cell function was detected in both LP and OP. However, more serious primary defect in insulin action was detected in LP compared to OP. These findings imply that early screening and intervention for PCOS would be therapeutic for Chinese women.
Effect of Distributed Attached Mass on the Vibration of Sandwich Panel Using Higher Order ESL Theory

In this paper, effects of adding a distributed attached mass added to the face sheets of sandwich panels on free vibration of the system are investigated. Higher order equivalent single layer (ESL) theory is expanded and used. Mass Inertias of the distributed attached mass are taking into account. Various design parameters including geometrical and material properties, such as density, thickness of the attached mass and the panel are investigated to show the decreasing effect on the fundamental natural frequency of the system due to the adding of the distributed attached mass.
Radial Basis Functions Collocation Methods for Model Based Level-Set Segmentation

We consider a recent parametric level-set segmentation approach where the implicit interface is the zero level of a continuous function expanded onto compactly supported radial basis functions, defined by their centers, coefficients and supports. We propose to introduce prior knowledge of the shape to be recovered by placing the centers quasi-uniformly over an uncertainty area.
Detecting and Tracking of Multiple People in Video based on Hybrid Detection and Human Anatomy Body Proportion

This paper addresses problems of detection and tracking of moving multiple people in a video stream. Detecting and tracking are fundamental tasks for future research into Human Computer Interaction (HCI). Detecting and Tracking multiple people in video are considered time consuming processes due to the amount of data a video contains, illumination changes, complex backgrounds and occlusions that occur as soon as people change orientations over time. This study focus on developing a fully automated system aims to Detecting and tracking multiple people in video, by analyzes sequential video frames based on hybrid detection algorithm, and tracking based on human body structure. The performance of the proposed system is tested through a series of experiments and human computer interaction application based human detection, tracking and identification. Identification is based on new clustering method mentioned in this paper. General Terms Video Processing, Computer vision systems, Human detection and tracking, Clustering.
When homoplasy mimics hybridization: a case study of Cape hakes (Merluccius capensis and M. paradoxus)

In the marine environment, an increasing number of studies have documented introgression and hybridization using genetic markers. Hybridization appears to occur preferentially between sister-species, with the probability of introgression decreasing with an increase in evolutionary divergence. Exceptions to this pattern were reported for the Cape hakes (Merluccius capensis and M. paradoxus), two distantly related Merluciidae species that diverged 3–4.2 million years ago. Yet, it is expected that contemporary hybridization between such divergent species would result in reduced hybrid fitness. We analysed 1,137 hake individuals using nine microsatellite markers and control region mtDNA data to assess the validity of the described hybridization event. To distinguish between interbreeding, ancestral polymorphism and homplasy we sequenced the flanking region of the most divergent microsatellite marker. Simulation and empirical analyses showed that hybrid identification significantly varied with the number of markers, model and approach used. Phylogenetic analyses based on the sequences of the flanking region of Mmerhk-3b, combined with the absence of mito-nuclear discordance, suggest that previously reported hybridization between M. paradoxus and M. capensis cannot be substantiated. Our findings highlight the need to conduct a priori simulation studies to establish the suitability of a particular set of microsatellite loci for detecting multiple hybridization events. In our example, the identification of hybrids was severely influenced by the number of loci and their variability, as well as the different models employed. More importantly, we provide quantifiable evidence showing that homoplasy mimics the effects of heterospecific crossings which can lead to the incorrect identification of hybridization.
Determination of the pore size of woven structures through image analysis

The paper presents an experimental procedure developed for determination of the pore size, shape and distribution in a single layer woven fabric, for the construction of a virtual model to be incorporated in a future CFD software package. The procedure is based on non-destructive observation and analysis of woven samples. 14 different samples of gray fabrics of 100 % cotton in plain and twill weaves are investigated. The results obtained allow the creation of reality more realistic virtual model of the woven structure, and theoretical investigation of its porosity and permeability through computer simulation.
Automatic Generation of Stereogram by Using Stripe Backgrounds

In this paper, we propose a new method that can generate stereograms (stereoscopic photographs) automatically by compositing foreground images and background images with chromakey using a two-tone stripe background. As to the image composition of foreground images and background images, a chromakey is usually used. However, the conventional chromakey uses the unicolored blue background, and has a problem that one’s clothes are regarded as the background if their colors are same. Therefore, we utilize the adjacency condition between two-tone striped areas on the background, and extract the foreground regions whose colors are same with the background. In addition, the stereogram consists of images for a left eye and those for a right eye. The relationships between foreground objects and background objects in composite images must be consistent. The relationships of objects between the left image and the right one must be also consistent. Therefore, the foreground images and the background images are merged by considering the geometric constraints.
Understanding repeated non-attendance in health services: a pilot analysis of administrative data and full study protocol for a national retrospective cohort

Introduction Understanding the causes of low engagement in healthcare is a pre-requisite for improving health services’ contribution to tackling health inequalities. Low engagement includes missing healthcare appointments. Serially (having a pattern of) missing general practice (GP) appointments may provide a risk marker for vulnerability and poorer health outcomes. Methods and analysis A proof of concept pilot using GP appointment data and a focus group with GPs informed the development of missed appointment categories: patients can be classified based on the number of appointments missed each year. The full study, using a retrospective cohort design, will link routine health service and education data to determine the relationship between GP appointment attendance, health outcomes, healthcare usage, preventive health activity and social circumstances taking a life course approach and using data from the whole journey in the National Health Service (NHS) healthcare. 172 practices will be recruited (∼900 000 patients) across Scotland. The statistical analysis will focus on 2 key areas: factors that predict patients who serially miss appointments, and serial missed appointments as a predictor of future patient outcomes. Regression models will help understand how missed appointment patterns are associated with patient and practice characteristics. We shall identify key factors associated with serial missed appointments and potential interactions that might predict them. Ethics and dissemination The results of the project will inform debates concerning how best to reduce non-attendance and increase patient engagement within healthcare systems. Significant non-academic beneficiaries include governments, policymakers and medical practitioners. Results will be disseminated via a combination of academic outputs (papers, conferences), social media and through collaborative public health/policy fora.
Solution-Processed, Flexible, and Transparent Non-Volatile Memory With Embedded Graphene Quantum Dots in Polymethylsilsesquioxane Layers

Non-volatile memory (NVM) devices using graphene quantum dots (GQDs) as charge trapping sites were fabricated with silver nanowires as top electrodes using solution process. The stacking structure consists of GQDs embedded between polymethylsilsesquioxane layers constructed on transparent flexible substrate. Hysteresis window was observed in the current-voltage plots, and the NVM devices are reprogrammable and stable up to 1 × 104 s with a distinct ON/OFF ratio of 104. In addition, the memory device shows the stable hysteresis window without obvious degradation upon bending under different curvature radii.
Compression of Isosurfaces

In many applications surfaces containing a large number of primitives occur. Geometry compression reduces storage space and transmission time for such models. A special case is given by polygonal isosurfaces generated from gridded volume data. However, most current state-of-the-art geometry compression systems do not capitalize on the structure that is characteristic of such isosurfaces, namely that the surfaces are defined by a set of vertices on edges of the grid. We propose a compression method for isosurfaces that is designed to exploit this feature. We tested our method for several isosurfaces from a CT scan of a human head. For this data set our coder outperformed state-of-the-art geometry compression methods by a factor of 2.2 to 2.8 in terms of compression ratio.
Registration of 3D Point Clouds and Meshes: A Survey from Rigid to Nonrigid

Three-dimensional surface registration transforms multiple three-dimensional data sets into the same coordinate system so as to align overlapping components of these sets. Recent surveys have covered different aspects of either rigid or nonrigid registration, but seldom discuss them as a whole. Our study serves two purposes: 1) To give a comprehensive survey of both types of registration, focusing on three-dimensional point clouds and meshes and 2) to provide a better understanding of registration from the perspective of data fitting. Registration is closely related to data fitting in which it comprises three core interwoven components: model selection, correspondences and constraints, and optimization. Study of these components 1) provides a basis for comparison of the novelties of different techniques, 2) reveals the similarity of rigid and nonrigid registration in terms of problem representations, and 3) shows how overfitting arises in nonrigid registration and the reasons for increasing interest in intrinsic techniques. We further summarize some practical issues of registration which include initializations and evaluations, and discuss some of our own observations, insights and foreseeable research trends.
P23H rhodopsin transgenic rat: correlation of retinal function with histopathology.

PURPOSE To correlate retinal functional changes with structural changes in P23H rhodopsin transgenic rats as a model of autosomal dominant retinitis pigmentosa. METHODS P23H heterozygote (lines 1 and 3) and Sprague-Dawley control rats were studied at 4 to 29 weeks by retinal histology, electroretinogram (ERG), and a-wave transduction modeling. RESULTS Both line 1 (faster degeneration) and line 3 (slower degeneration) showed progressive rod outer segment (ROS) shortening and outer nuclear layer (ONL) cell loss with age. ERG b-wave maximum amplitude (Vb(max)) decreased with age, but b-wave threshold remained constant within each line despite progressive ONL thinning and ROS shortening. The only exception was in line 1 at 29 weeks, which showed a slight threshold change relative to earlier ages. Va(max) and a-wave threshold changed more rapidly and were more sensitive than the b-wave in reflecting histologic degeneration. Va(max) was linearly proportional to the product of (ROS x ONL) across a two log unit range of data combined from both lines. The photopic b-wave was normal for both lines until the ONL thinned beyond 50%. Phototransduction sensitivity was normal for both lines, and dark-adaptation recovery after bleaching rhodopsin was normal. CONCLUSIONS The P23H transgenic rat has a slow rod degeneration with initially normal cone function, consistent with clinical findings of P23H patients. However, the normal bleach recovery and the normal phototransduction sensitivity in this rat model are different from human P23H disease. a-Wave measures were more sensitive than the b-wave for tracking changes. b-Wave threshold was inexplicably poor for tracking degeneration. Although line 1 degenerated faster than line 3, the functional-structural correlates were the same. The tight linear relationship between saturated a-wave amplitude and the product of (ROS x ONL) indicates that the density of cGMP-gated channels per unit ROS plasma membrane area remains constant over a wide range of degenerations.
