Ambient Systems , Networks and Technologies ( ANT-2014 ) Semantic Annotation Tool for Annotating Arabic Web Documents

The vision of semantic Web is to have a Web of data instead of Web of documents in a form that can be processed by machines. This vision could be achieved in the existing Web using semantic annotation. Due to exponential growth and huge size of the Web sources, there is a need to have a fast and automatic semantic annotation of Web documents. Arabic language has received less attention in semantic Web research compared to Latin languages especially in the field of semantic annotation. In this paper, we present an automatic annotation tool that supports the semantic annotation of Arabic language Web documents. The tool takes a URL of Web document and the corresponding ontology then produces an external annotation of the Web document using Resource Description Framework (RDF) language. The annotation tool's output could be used by semantic search engines to achieve higher recall and precision. To evaluate the performance of the tool, three domain ontologies of food, nutrition and health were used with manually annotated documents related to those domains. The initial results show a promising performance which will support the research in the semantic Web with respect to Arabic language. © 2014 The Authors. Published by Elsevier B.V.

"The Bar Harbor Course": a 30-year veteran in the teaching of human genetics.

The year 1960 marked the inaugural year of the "Short Course in Medical Genetics" held at the Jackson Laboratory in Bar Harbor, ME. The location on Mt. Desert Island and the proximity of Acadia National Park offer a beautiful setting for a summer course. The idea for the course was conceived by Victor McKusick and John Fuller over "lunch at a well-known Bar Harbor restaurant" (McKusick 1981) during Dr. McKusick's visit to Jackson Laboratory at the invitation of its director, Earl Green (McKusick 1989). A joint effort of The Johns Hopkins University and The Jackson Laboratory, the course has been held for 2 wk every summer for the past 30 years. Between 1967 and 1977, it alternated yearly with the "Short Course in Experimental Mammalian Genetics;' which was primarily concerned with studies of the mouse. Since 1977, the courses have been combined and called the "Short Course in Medical and Experimental Mammalian Genetics. " The course was exclusively supported by the National FoundationMarch of Dimes through 1984. Although March of Dimes support has continued, the prominent support in recent years has come from the National Institute for Child Health and Human Development of the National Institutes of Health and from the Lucille P. Markey Charitable Trust. The Short Course was developed to "teach the teachers. " It is not intended to be a symposium, although many of the lecturers have included information from their current research to illustrate various techniques and concepts. "As originally outlined, the purpose of this course was to provide for faculty members in medical schools, universities and certain other professional schools an opportunity to become acquainted with the
The Forward Valuation of Compound Options

The Black-Scholes (BS) model gives the value of a European option when the underlying follows a lognormal distribution with constant volatility. American options, however, require more elaborate procedures, typically coming from what amounts to an approximate solution to a “backward” partial differential equation. Time varying volatility is fairly easily accommodated for European options, so long as it is non-stochastic, but for American options things become more complicated. More complex derivatives, involving compound optionality, for example, can be solved for the simplest cases, but quickly get beyond easy application of current techniques, as complexity grows. In any case, the existing solutions are such that each option requires its own full valuation routine. In this rather remarkable article, Buraschi and Dumas develop a new technique, based on solving a forward equation, that greatly simplifies the entire process. The result is a valuation algorithm that easily handles time varying (non-stochastic) volatility, compound optionality and American exercise. Unlike the “backward” technique, their approach produces an entire valuation surface defined in terms of strike and time to maturity, given current date and stock price. This allows valuation of multiple options on the same underlying with essentially no more computation than pricing a single one.
An M protein with a single C repeat prevents phagocytosis of Streptococcus pyogenes: use of a temperature‐sensitive shuttle vector to deliver homologous sequences to the chromosome of S. pyogenes

The major virulence factor of the important human pathogen Streptococcus pyogenes is the M protein, which prevents phagocytosis of the bacterium. In different strains of streptococci, there are over 80 serologically different M proteins and there are additional M‐like proteins, some of which bind immunoglobulins. Although the sequence of the M molecules differs among different S. pyogenes strains, all M proteins, and some of the immunogiobulin‐binding molecules, have at least two copies of the C repeat region. We describe construction of a deletion mutation in S. pyogenes, which has only one C repeat copy, and show that the mutant strain is still resistant to phagocytosis. The mutation was constructed in vitro and used to replace the resident emm allele in an S. pyogenes strain. To facilitate homologous recombination into the streptococcal chromosome, we adapted a shuttle vector which is temperature sensitive for replication in Gram‐positive bacteria but not in Gram‐negative hosts. This new method for delivery of a homologous DNA fragment to the S. pyogenes chromosome is efficient and reproducible and should be of general use.
A simplified model predictive control to eliminate common mode voltage of an AC motor fed by a neutral point clamped inverter

This paper presents an approach to completely eliminate common-mode voltage (CMV) of an AC motor fed by a three-level neutral point clamped (NPC) inverter. CMV is produced at the star point of an AC machine fed from the inverter. Its parasitic coupling with the motor frame has a negative effect on the motor itself and other equipment, particularly in underground environment. The proposed approach to eliminate CMV, in combination with capacitor voltage balancing, is based on simplified model predictive control (MPC). Simulation results implemented in MATLAB-Simulink environment confirm that the proposed MPC algorithm successfully removes CMV, which makes it a promising control technique in industrial applications.
CONTRASTIVE SUMMARIZATION : COMPARING OPINIONS OF CZECH SENATORS

In this paper, we present a novel approach to contrastive summarization, i.e. a specific type of summarization, which aims to compare two documents (or groups of documents) on semantic and also sentiment level. The final output of contrastive summarization is a pair of summaries, depicting what topics are most often discussed with the largest difference in opinions of the authors. We explore the possibilities of combining the latent semantic information with the information about the opinions of the authors. First, we describe related works, which show, that this problem can be approached from many different directions. Next, we present our own algorithm, based on Latent Semantic Analysis, which computes scores for excerpts of the original text and based on these, it chooses best excerpts that should be included into the final summaries. Finally, we present the evaluation of our algorithm, using speeches from Czech senate.
Tobacco industry campaign contributions are affecting tobacco control policymaking in California.

OBJECTIVE To test the hypothesis that tobacco industry campaign contributions are influencing the behavior of members of the California legislature. DESIGN Multivariate simultaneous-equations regression was used to analyze data on campaign contributions from the tobacco industry to members of the California legislature in 1991 and 1992, members' tobacco control policy positions, and members' personal characteristics. DATA SOURCES The following sources were analyzed: campaign contributions from disclosure statements filed with the California Fair Political Practices Commission; constituent attitudes on tobacco control from the California Tobacco Survey; legislators' personal characteristics, from a survey of key informants conducted by the California Journal; and the tobacco policy score, a survey of key informants working on tobacco issues in the state legislature. Specific voting on tobacco-related bills was also analyzed. SETTING California legislature in 1991 and 1992. PATIENTS OR OTHER PARTICIPANTS All members of the California legislature in 1991 and 1992. MAIN OUTCOME MEASURES Tobacco policy score, campaign contributions, and votes on individual tobacco-related bills. RESULTS The tobacco industry is having a statistically detectable effect on behavior of members of the California legislature on tobacco policymaking. On a scale of 0 to 10, a legislator's tobacco policy score dropped (ie, became more protobacco industry) by -0.11 for every $1000 in tobacco campaign contributions, after accounting for the fact that a more protobacco position was associated with greater contributions ($1855 for each -1.0 reduction in score). Members who were rated as effective received larger contributions from the industry. Members rated higher in integrity and intelligence were more antitobacco (higher scores) and Republicans more protobacco (lower scores) after taking into account the effects of contributions from the industry. Constituent attitudes were not reflected in legislators' perceived behavior. CONCLUSION Tobacco industry campaign contributions influence California legislators in matters related to tobacco policymaking, independent of constituents' support for tobacco control.
A systematic methodology to design analog predistortion linearizer for dual inflection power amplifiers

This paper presents a systematic methodology to design a diode-based RF predistortion linearizer that can be used to linearize power amplifiers with dual inflection points in their distortion characteristics. The proposed structure contains anti parallel configuration of Schottky diodes, complemented with a PIN diode in parallel, connected to through and coupled ports of a 90° hybrid coupler using λ/4 transmission lines. The use of a PIN diode in the linearizer provides it with an extra level of freedom in achieving the desired level of amplitude and inflection depth in the AM/AM characteristic. A systematic design procedure using this configuration is proposed and applied to linearize a commercial power amplifier. Two tone test experimental results show that the IM3 cancellation of 10 dB in 1 MHz separation between tones at 2.14 GHz can be achieved.
High-Level Switching Activity Prediction Through Sampled Monitored Simulation

This paper presents a sample-based technique to predict the switching activity of digital circuits. It is an improvement to PowerSC, a SystemC library extension that enables a fast and easy-to-use way of gathering switching activity from SystemC descriptions. The experimental results reveal that it can dramatically reduce the monitoring time of the simulation, with a minimal loss of accuracy with respect to estimates provided by an industrial tool. Several tests realized in a case study with a real-world design obtained reductions in the monitoring time of up to 99% with average errors of no more than 0.05%.
Typing of Legionella pneumophila strains by polymerase chain reaction-mediated DNA fingerprinting

Well-defined Legionella pneumophila strains were analyzed by amplification of variable genomic regions with arbitrary and repeat sequence primers. Clinical and environmental outbreak-related isolates showed closely related amplicon patterns. Eleven strains of unrelated origins displayed 10 distinct patterns. Fingerprinting of L. pneumophila by polymerase chain reaction appeared to have the potential of being as epidemiologically useful as other genotypic methods.
Dual Two-Dimensional Fuzzy Class Preserving Projections for Facial Expression Recognition

This paper proposes a novel algorithm for image feature extraction-the dual two-dimensional fuzzy class preserving projections ((2D)2FCPP). The main advantages of (2D)2FCPP over two-dimensional locality preserving projections (2DLPP) are: (1) utilizing the fuzzy assignation mechanisms to construct the weight matrix, which can improve the classification results; (2) incorporating 2DLPP and alternative 2DLPP to get a more efficient dimensionality reduction method-(2D)2LPP.
Brown snake envenoming: Why are we left in the dark?

Ou et al. report an interesting case of presumed brown snake envenoming, but we are concerned that some statements about diagnosis, treatment and antivenom dosing are not evidence based. Most importantly it is unclear why the authors do not confirm brown snake envenoming by testing the patient’s blood for brown snake venom. They provide a discussion about the utility of the commercial venom detection kit, but do not discuss measurement of venom in blood using venom-specific enzyme immunoassays. Such testing is freely available for any snake bite in Australia from the Australian Snakebite Project. Although, they conclude the case is Eastern Brown Snake envenoming, they only provide circumstantial evidence for this. Why leave the reader and patient in the dark about the diagnosis? The authors discuss the dose of antivenom and suggest that current guidelines that recommend only one vial 3 are ‘‘precariously narrow clinical strategy’’. However, they provide no reference or evidence to support their view that two vials should be given. The Australian snakebite project has demonstrated that one vial is more than sufficient for all brown snake bites in a large series of cases and followed this up by demonstrating that low concentrations of venom detected post-antivenom are in fact bound venom. It is unclear how Ou et al. arrive at two vials, considering this is four times the original dose recommended by the Commonwealth Serum Laboratories based on venom yields, and only a fifth of the huge doses recommended by some clinicians a decade ago. It is important to note that at least one of the authors receives funding and provides advice to the antivenom manufacturer, CSL Ltd. It is also unclear how the authors can make a diagnosis of non-ST elevation myocardial infarction in a patient who has no chest pain (or other symptomatology), no electrocardiogram changes and only an elevated troponin. The patient is not reported to have any further investigations as per Australian guidelines. She was discharged home to have Holter monitoring and a transthoracic echocardiogram, but these are not reported. Elevated troponins can occur in many non-ischaemic heart disease conditions, e.g. pulmonary embolism, myocarditis, sepsis and have been previously reported in brown snake envenoming and are most likely due to the initial collapse that is associated with hypotension.
The performance and scalability of SHMEM and MPI‐2 one‐sided routines on a SGI Origin 2000 and a Cray T3E‐600

This paper compares the performance and scalability of SHMEM and MPI‐2 one‐sided routines on different communication patterns for a SGI Origin 2000 and a Cray T3E‐600. The communication tests were chosen to represent commonly used communication patterns with low contention (accessing distant messages, a circular right shift, a binary tree broadcast) to communication patterns with high contention (a ‘naive’ broadcast and an all‐to‐all). For all the tests and for small message sizes, the SHMEM implementation significantly outperformed the MPI‐2 implementation for both the SGI Origin 2000 and Cray T3E‐600.

Impact of Protocols and Network Configuration on Node-Level Availability in Sensor Networks

We investigate the effects of the performance of sensor networks on network availability and in turn evaluate the impact of protocols and network configuration on these effects. The typical wireless sensor network of the future consists of a large number of micro-sized sensors that are equipped with batteries of limited capacity. In such a network, energy consumption is one of the most important issues. Several representative protocols that are applied in ring and linear network configurations are analyzed, and explicit formulae for network availability are derived for each of them. Numerical values derived by using these formulae yielded the surprising result that backup routes do not always improve network availability. This is because the loads imposed by the backup routes on network segments that do not include dead sensor nodes reduce sensor-node lifetimes in these segments.
In vitro assay of cell-free turkey herpesvirus.

SUMMARY The susceptibility of cultures of chicken cells to cell-free turkey herpesvirus (HVT) was affected by the age of the culture but not by cell type, cell passage, or age and genetic constitution of the donor. Chicken embryo fibroblasts (CEF), chicken kidney (CK), and chicken embryo kidney cells all were of equal sensitivity, but duck embryo fibroblasts were only one-fourth as susceptible as the chicken cells. Three- or 24-hour CEF and 24-hour CK cell monolayers were more sensitive than 48- or 72-hour cultures. CEF cells inoculated while in suspension were less sensitive than those inoculated as monolayer cultures. About 7.5 X 106 CEF seeded per 60mm Petri dish was found optimal. The type and pH of the virus diluent and the presence or absence of a chelator in the inoculum were without effect on virus titer, but a stabilizer containing sucrose and bovine albumin (SPA) rendered the virus less thermolabile and less susceptible to freezethaw cycles. Mechanical treatments of the inoculum, such as vigorous pipetting or sonic vibration, increased virus titers, apparently by causing better virus dispersion.
A review: Approximate image and video compression

There is a large demand for high dynamic range system that operates at high resolutions. Particularly in high quality videos and images over internet. Internet protocol networks are prominent areas where such requirements are more. Some other fields where image and video compression techniques used are traffic cameras, automatic surveillance, geospatial remote sensing, automotive industry, homeland security. Multiplier-free approximate DCT transform will be implemented having very low circuit complexity and superior compression performance. DCT has remarkable property of energy compaction due to which it is used in multiple of compression standards. The proposed system uses Spartan-III FPGA on which such approximations can be implemented using additions only which possesses a very low computational complexity. In this transform image compression is done using Spartan-III FPGA then this compressed image is again decompressed in MATLAB.
Evaluation of the effect of autologous mesenchymal stem cell injection in a large‐animal model of bilateral kidney ischaemia reperfusion injury

Objectives: Adult mesenchymal stem cells (MSC) have been proven to be of benefit to the kidney in different experimental models of renal injuries. All studies have been performed in valuable rodent models, but the relevance of these results to large mammals and ultimately, to humans remains unknown. Therefore, the aim of this study was to investigate the effect of MSC transplantation in an alternative ovine large‐animal model of bilateral kidney ischaemia reperfusion injury.
Late Presentation of HIV-Infected Individuals

Late presentation remains a major concern despite the dramatically improved prognosis realized by ART. We define a first presentation for HIV care during the course of HIV infection as ‘late’ if an AIDS-defining opportunistic disease is apparent, or if CD4+ T-cells are <200/μl. In the Western world, approximately 10 and 30% of HIV-infected individuals still present with CD4+ T-cells <50 and <200/μl, respectively; estimates are substantially higher for developing countries. Diagnosis and treatment of opportunistic diseases and intense supportive in-hospital care take precedence over ART. Benefits of starting ART without delay, that is, when opportunistic diseases are still active, include faster resolution of opportunistic diseases and a decreased risk of recurrence. The downside of starting ART without delay could include toxicity, drug interactions and immune reconstitution inflammatory syndrome (IRIS). Among asymptomatic or oligosymptomatic individuals presenting late, where ART and primary prophylaxis are initiated, ∼10–20% will become symptomatic from drug toxicity or undiagnosed opportunistic complications, including IRIS, which require appropriate therapies. In this review we describe late presentation to HIV care, the scale of the problem, the evaluation of a late-presenting patient and challenges associated with initiation of potent anti-retroviral therapy (ART) in the setting of acute opportunistic infections and other comorbidities.
Chondrogenesis by bone marrow‐derived mesenchymal stem cells grown in chondrocyte‐conditioned medium for auricular reconstruction

Bone marrow‐derived mesenchymal stem cells (BMSCs) can be obtained by minimally invasive means and would be a favourable source for cell‐based cartilage regeneration. However, controlling the differentiation of the BMSCs towards the desired chondrogenic pathway has been a challenge hampering their application. The major aim of the present study was to determine if conditioned medium collected from cultured auricular chondrocytes could promote chondrogenic differentiation of BMSCs. Auricular chondrocytes were isolated and grown in BMSC standard culture medium (SM) that was collected and used as chondrocyte‐conditioned medium (CCM). The BMSCs were expanded in either CCM or SM for three passages. Cells were seeded onto fibrous collagen scaffolds and precultured for 2 weeks with or without transforming growth factor‐beta 3 (TGF‐β3). After preculture, constructs were implanted subcutaneously in nude mice for 6 and 12 weeks and evaluated with real‐time polymerase chain reaction, histology, immunohistochemistry and biochemistry. Real‐time polymerase chain reaction results showed upregulation of COL2A1 in the constructs cultured in CCM compared with those in SM. After 12 weeks in vivo, abundant neocartilage formation was observed in the implants that had been cultured in CCM, with or without TGF‐β3. In contrast, very little cartilage matrix formation was observed within the SM groups, regardless of the presence of TGF‐β3. Osteogenesis was only observed in the SM group with TGF‐β3. In conclusion, CCM even had a stronger influence on chondrogenesis than the supplementation of the standard culture medium with TGF‐β3, without signs of endochondral ossification. Efficient chondrogenic differentiation of BMSCs could provide a promising alternative cell population for auricular regeneration. Copyright © 2016 John Wiley & Sons, Ltd.
Towards Context-based Mediation for Semantic Web Services Composition

Web services composition is a keystone towards the development of interoperable systems. However, desp ite several efforts for explicit semantic description, Web services still face data-heterogeneity chal lenges. Correct interpretation of data exchanged between composed Web services is hampered by differen t implicit modeling assumptions and representations. In this paper, we demonstrate the importance of c ontext to facilitate data exchange, and describe a context representation model for Web services. Then , we present a context-based mediation architecture that helps performing meaningful composition.
