Efficient and portable multi-tasking for heterogeneous systems

Modern computing systems comprise heterogeneous designs which combine multiple and diverse architectures on a single system. These designs provide potentials for high performance under reduced power requirements but require advanced resource management and workload scheduling across the available processors. Programmability frameworks, such as OpenCL and CUDA, enable resource management and workload scheduling on heterogeneous systems. These frameworks fully assign the control of resource allocation and scheduling to the application. This design sufficiently serves the needs of dedicated application systems but introduces significant challenges for multi-tasking environments where multiple users and applications compete for access to system resources. This thesis considers these challenges and presents three major contributions that enable efficient multi-tasking on heterogeneous systems. The presented contributions are compatible with existing systems, remain portable across vendors and do not require application changes or recompilation. The first contribution of this thesis is an optimization technique that reduces hostdevice communication overhead for OpenCL applications. It does this without modification or recompilation of the application source code and is portable across platforms. This work enables efficiency and performance improvements for diverse application workloads found on multi-tasking systems. The second contribution is the design and implementation of a secure, user-space virtualization layer that integrates the accelerator resources of a system with the standard multi-tasking and user-space virtualization facilities of the commodity Linux OS. It enables fine-grained sharing of mixed-vendor accelerator resources and targets heterogeneous systems found in data center nodes and requires no modification to the OS, OpenCL or application. Lastly, the third contribution is a technique and software infrastructure that enable resource sharing control on accelerators, while supporting software managed scheduling on accelerators. The infrastructure remains transparent to existing systems and applications and requires no modifications or recompilation. In enforces fair accelerator sharing which is required for multi-tasking purposes.
Homology Modeling of Human Alpha-Glucosidase Catalytic Domains and SAR Study of Salacinol Derivatives

Maltase-glucoamylase (MGAM) and sucrase-isomaltase (SI) belong to human intestinal alpha-glucosidase and their N-terminal side catalytic domains are called NtMGAM and NtSI, and their C-terminal side catalytic domains are called CtMGAM and CtSI. As an antidiabetic, alpha-glucosidase inhibitor is required to bind to all of these domains to inhibit disaccharides hydrolysis. Salacinol and kotalanol isolated from Salacia reticulata are novel seed compounds for al-pha-glucosidase inhibitor. Even though the complex structures of NtMGAM or NtSI have been determined experimen-tally, those of CtMGAM and CtSI have not been revealed. Thus, homology modeling for CtMGAM and CtSI has been performed to predict the binding mode of salacinol and its derivatives for each domain. The binding affinities for these compounds were also calculated to explain the experimental structure-activity relationships (SARs). After a docking study of the derivatives to each catalytic domain, the MM/PBSA method has been applied to predict the binding affinities. The predicted binding affinities were almost consistent with the experimental SARs. The comparison of the complex structures and binding affinities provided insights for designing novel compounds, which inhibit all catalytic domains.
Prenatal syphilis infection is a possible cause of preterm delivery among immigrant women from eastern Europe

Objective:to evaluate the prevalence of maternal syphilis at delivery and neonatal syphilis infection in an Italian urban area, in connection with the increased flow of immigration. Study design: A prospective surveillance study was carried out in Bologna, Italy, from November 2000 to March 2006. All pregnant women were screened for syphilis at delivery. Infants born to seropositive mothers were enrolled in a prospective follow-up. Results: During the study period 19 205 women gave birth to 19 548 infants. A total of 85 women were seropositive for syphilis at delivery. The overall syphilis seroprevalence in pregnant women was 0.44%, but it was 4.3% in women from eastern Europe and 5.8% in women from Central–South America. Ten women were first found positive at delivery, as they did not receive any prenatal care. Nine of these were from eastern Europe. All their infants were asymptomatic, but six had both reactive immunoglobulin (Ig)M western blot and rapid plasma reagin tests and were considered prenatally infected. Three of six were preterm (gestational age <37 weeks). Conclusions: In Italy, congenital syphilis infection is strictly related to immigration from eastern Europe. Although it is asymptomatic, it could cause premature delivery. Therefore, it is necessary to perform serological tests during the third trimester in mothers coming from endemic areas to adequately treat syphilis in pregnancy and prevent congenital infection. If the mother’s test results are not available at delivery, it is necessary to investigate the newborn, especially if it is born prematurely.
Toward Optimal Streaming Feature Selection

Recently, real-time data brings explosion of big data that is challenged traditional data mining techniques. Analyzing data in real-time would allow making better decisions on realtime. Usually, big data contains many irrelevant and redundant data. Therefore, removing and discarding these data is essential. Streaming feature selection involving big data has generally been viewed as a solution for selecting informative features that lead to accurate learning models. In this paper we introduce an efficient algorithm for selection of features from a feature stream by online feature grouping. This technique will be useful in big data analytics due to its efficiency and scalability. The main contribution of this work is to solve the challenge of extremely high dimensional of big data by delivering the streaming feature grouping and selection algorithm. In our approach the algorithm is designed with the idea of grouping similar features to reduce the redundancy and to handle the stream of features in an online fashion. Experimental results have demonstrated that our proposed algorithm shown superior performance in terms of prediction accuracy and running time.

The proposed technique helps in automatic identification of intracardiac masses in echocardiograms. This technique aims to help cardiac surgeons to classify tumor and thrombi in patients with cardiac diseases in an easy way thereby improving accuracy and minimizing diagnosis time. It makes use of non-local means algorithm (NLM) for the removal of Rayleigh scattering noise and the despeckled image is processed and segmented with the help of K-singular value decomposition (K-SVD) and sparse representation classifier (SRC) to classify the masses. It aims at better and faster classification results
L'outillage de pierre taillée néolithique en Grèce : approvisionnement et exploitation des matières premières

Les hypotheses les plus courantes concernant l'approvisionnement en matieres premieres au Neolithique sont celle de l'approvisionnement direct aux sources, par les utilisateurs, et celle d'un echange de proche en proche. Toutefois, une analyse technologique du materiel lithique taille demontre une grande variete des systemes d'exploitation des matieres premieres qui se satisfait mal d'une modalite unique d'approvisionnement, quelle qu'elle soit. En outre, aucune des deux hypotheses prevalentes ne s'accorde avec les distributions observees et les contraintes creees par des deplacements jusqu'aux sources, notamment au Neolithique ancien et moyen pour l'obsidienne melienne. La reprise synthetique des donnees oriente vers deux axes : d'une part l'hypothese d'une double specialisation, dans l'approvisionnement et la production, au Neolithique ancien et moyen. D'autre part, l'hypothese du developpement d'une aire d'approvisionnement direct au Neolithique recent et final des lors que les Cyclades deviennent regulierement exploitees. La nature de la production s'en voit modifiee : elle presente, dans cette meme aire meridionale, des caracteres moins extensifs et moins specialises dans les savoir-faire. Ces conclusions conduisent a reposer le probleme de la nature des societes paysannes du Neolithique, de la place de l'echange et des specialisations techniques, et des fondements des transformations qui conduiront a l'Âge du Bronze.
A new bacterial disease of mung bean and cowpea for Australia

A new bacterial disease was detected on mung bean crops in 1984 in central and southern Queensland. The symptoms were marginal and interveinal necrosis of the leaves with vascular browning in a small percentage of affected plants. No wilting was observed. The same symptoms were later detected on cowpeas in southern Queensland. Disease incidence in the commercial crops of mung bean and cowpea surveyed, ranged from leaf symptoms on an occasional plant to 5°/o-8°/o of the crop affected. However, disease incidence as high as 90% has been reported from other districts. The disease appeared to be most severe in rain-grown crops suffering from moisture stress. The pathogen was identified as Curtobacterium flaccumfaciens subsp. flaccumfaciens on biochemical tests and host pathogenicity. It was shown to be seed transmissible by artificial seed inoculation and pathogenic to soybean and French bean but not to tomato. A toxin was involved in pathogenesis.
Biotyping and genotypic diversity among oral Candida albicans strains from caries-free and caries-active healthy children

Candida albicans oral strains collected from caries-free and caries-active healthy children ranging from 24 to 36 months old, were studied. The aim of the study was to determine proteinase and phospholipase activities produced by Candida albicans in the two groups and to determine the phenotypic diversity of these enzymes based on genetic polymorphism using the AP-PCR method. Strains identified by morphological and fermentation tests as C. albicans were grown in proteinase and phospholipase agar media at 37oC for 7 and 4 days, respectively. After the incubation period, the enzyme activity of the proteinase and phospholipase positive strains was measured. All strains were subjected to AP-PCR, using the arbitrary primer AP-3. The enzymatic analysis showed no differences between the two groups. The AP-PCR method was effective in demonstrating intra-individual genetic polymorphism in C. albicans, showing a greater clonal diversity in caries-active versus caries-free children. Dendograms of similarity showed only intra-individual clonal lineage. The results suggest that the enzymatic profile does not depend on the genotypic characteristics of the strains.
The Prevalence of Symptomatic, Diabetic Neuropathy in an Insulin-treated Population

The prevalence of symptomatic sensorimotor polyneuropathy has been determined in a population of 382 insulin-treated diabetic subjects aged 15–59 yr. Forty-one subjects (10.7%) were found to have diabetic neuropathy, according to strict diagnostic criteria that required the presence of symptoms and signs of nerve dysfunction in the absence of peripheral vascular disease. There was a significant correlation between glycosylated hemoglobin levels and motor conduction velocity in the median and peroneal nerves in all subjects. This finding further emphasizes the importance of metabolic factors related to hyperglycemia in the impaired nerve function seen in diabetic patients.
NIVEL DE BIFURCACION DE LA ARTERIA BRAQUIAL Y SUS RELACIONES CON EL NERVIO MEDIANO

Las arterias del miembro superior presentan variaciones debido fundamentalmente a modificaciones ocurridas durante el desarrollo embriologico. La bifurcacion de la arteria braquial en arterias radial y ulnar ocurre a nivel del codo pudiendo esta ser mas alta o mas baja. Con el proposito de determinar el nivel de bifurcacion de esta arteria y sus relaciones con el nervio mediano, realizamos un estudio morfometrico de estos parametros en 72 miembros superiores de cadaveres formolizados, adultos, brasilenos, de ambos sexos, utilizando para ello la diseccion y registrando los datos morfometricos con un paquimetro digital. Como punto de referencia se considero a la linea biepicondilar (LBE). En el 87, 5 % de los casos, la arteria braquial se bifurco distal a esta linea y en el 11,1 % fue proximal a la misma. La distancia promedio para la primera fue de 38,4 mm en el sexo masculino y de 30,00 mm en el femenino. El test de regresion linear aplicado para ver la posible relacion entre este nivel y la longitud del brazo no fue estadisticamente significativo. Cuando la bifurcacion fue distal a la LBE el nervio mediano cruzo ventralmente a la arteria braquial en 54,9 % de los casos y dorsalmente en 23,5 %. El punto de cruzamiento fue localizado a 64,6 mm de la linea biepicondilar
Energy-Efficient Routing in Multi-Community DTN with Social Selfishness Considerations

Delay-Tolerant Networks (DTNs) are wireless mobile networks, where the nodes are sparse and end-to- end connectivity is rare. Since DTN nodes are mostly energy-limited devices, there is an immediate need to have energy-efficient routing protocols, allowing the network to perform better and function longer. Besides, in the real world, people carrying the nodes form a lot of communities because of similar interests, and they behave with social selfishness. How to improve the energy efficiency in multi-community scenarios has been an important problem. In this paper, we analytically model the performance of epidemic routing protocols in multi-community scenarios with social selfishness considerations using the Ordinary Differential Equations (ODEs). Further, an energy-efficient copy-limit-optimized algorithm based on the Box's complex method for epidemic routing is proposed, which is designed to determine the optimal copy limit in multiple communities, and can improve the energy efficiency effectively. At last, both the numerical and simulation results show that the routing protocol with the proposed algorithm can reduce the energy consumption effectively, and the impact of social selfishness is also analyzed.
Avaliação isocinética de rotadores externos e internos do ombro de atletas sobre cadeira de rodas e indivíduos sedentários – estudo comparativo

O efeito do desequilibrio muscular na performance e na gênese de lesões em atletas vem adquirindo interesse crescente. Esse desequilíbrio muscular tem sido identificado como ocorrência comum e induzido pelo treino. Recentemente, tem-se sugerido que esse causaria o aumento do risco de lesões nos atletas. Há muitas pesquisas a esse respeito na literatura direcionada são joelho. Pouco se tem a respeito do ombro, alvo de lesões freqüentesem esportistas . Os poucos trabalhos que se tem a esse respeito constam de estudos isocinéticos em atletas de beisebol, natação, tênis e pólo aquático. Esses demonstram alterações importantes no equilíbrio muscular dos ombros dos atletas estudados quando comparados a grupos-controle, em especial o fortalecimento excessivo de rotadores internos em relação a rotadores externos e de adutores em relação a abdutores. O possível papel desse desequilíbrio muscular no desenvolvimento de dores, tendinites, síndromes do impacto e subluxações anteriores tem sido sugerido e estudado.
Anomalous Resistivity in the Auroral Plasma.

The stabilization of fast precipitating electron bursts in the auroral plasma by parametric spectral transfer of waves out of their region of generatlon results in a nonlinear equilibrium, composed of an enhanced wave spectrum of high frequency oscillations and very low frequency ion density fluctuations. It is shown that the wave particle scattering due to the enhanced spectrum of the low phase velocity ion fluctuations can increase the d.c. resistivity of the auroral plasma by several orders of magnitude.

VARIOUS FRAMEWORKS 2 . 1 Deep 2 learning : Deep belief networks ( DBN )

Object detection and recognition are important problems in computer vision and pattern recognition domain. Human beings are able to detect and classify objects effortlessly but replication of this ability on computer based systems has proved to be a non-trivial task. In particular, despite significant research efforts focused on meta-heuristic object detection and recognition, robust and reliable object recognition systems in real time remain elusive. Here we present a survey of one particular approach that has proved very promising for invariant feature recognition and which is a key initial stage of multi-stage network architecture methods for the high level task of object recognition.
Computational Method for Representing the Simultaneous Hemodynamic Relationship between Oxy-Hemoglobin Delivery and Deoxy-Hemoglobin Extraction in Neural Tissues

In this study, we propose the use of phase space plot analysis to characterize coupling relationships between two simultaneously recorded hemodynamic variables, i.e., oxyhemoglobin (oxy-Hb) and deoxy-hemoglobin (deoxy-Hb), using functional near-infrared spectroscopy (fNIRS). To demonstrate the validity of the proposed method, we analyze hemodynamic data recorded from human subjects performing an orthogonal movement task. Our results show that phase space plots can quantify the dynamic time-varying relationships between the two variables based on the trajectory of the loci of data points in the phase space plots. In particular, the location of the phase space plots in different quadrants provides a specific coupling relationship between the two hemodynamic variables. The orientation of the loci of points characterizes further the relationship between these two variables, which can be directly or inversely proportional. The locus of the trajectory along a straight line or an elliptical path can reveal the phase relationship between the two variables. Thus, using phase space analysis on these two simultaneously recorded hemodynamic variables can uniquely identify the movement direction encoded by the motor cortex.
Solution structure of a cyanovirin-N:Man alpha 1-2Man alpha complex: structural basis for high-affinity carbohydrate-mediated binding to gp120.

BACKGROUND Cyanovirin-N (CVN) is a novel, 11 kDa cyanobacterial protein that potently inhibits viral entry by diverse strains of HIV through high-affinity carbohydrate-mediated interactions with the viral envelope glycoprotein gp120. CVN contains two symmetry-related carbohydrate binding sites of differing affinities that selectively bind to Man(8) D1D3 and Man(9) with nanomolar affinities, the carbohydrates that also mediate CVN:gp120 binding. High-resolution structural studies of CVN in complex with a representative oligosaccharide are desirable for understanding the structural basis for this unprecedented specificity. RESULTS We have determined by multidimensional heteronuclear NMR spectroscopy the three-dimensional solution structure of CVN in complex with two equivalents of the disaccharide Manalpha1-2Manalpha, a high-affinity ligand which represents the terminal-accessible disaccharide present in Man(8) D1D3 and Man(9). The structure reveals that the bound disaccharide adopts the stacked conformation, thereby explaining the selectivity for Man(8) D1D3 and Man(9) over other oligomannose structures, and presents two novel carbohydrate binding sites that account for the differing affinities of the two sites. The high-affinity site comprises a deep pocket that nearly envelops the disaccharide, while the lower-affinity site comprises a semicircular cleft that partially surrounds the disaccharide. The approximately 40 A spacing of the two binding sites provides a simple model for CVN:gp120 binding. CONCLUSIONS The CVN:Manalpha1-2Manalpha complex provides the first high-resolution structure of a mannose-specific protein-carbohydrate complex with nanomolar affinity and presents a new carbohydrate binding motif, as well as a new class of carbohydrate binding protein, that facilitates divalent binding via a monomeric protein.
Morphological changes in Schistosoma mansoni caused by the mutagen ethyl methane sulphonate

ABSTRACT Three week old Schistosoma mansoni, cultured for up to sixty days after exposure to ethyl methane sulphonate, showed extensive ballooning which often involved most of the worm's body. Other changes included tegumental breakdown which was expressed in varying degrees from mild hernia to total disruption of body shape. Increase in gut size involved stretching of the epithelium and inclusions ranging from masses of disrupted tissue to large, dark opaque masses. Masses were also occasionally seen in the fluid filled spaces of worms. Evidence of hyperplasia was not observed in any of the histological examinations performed.
Design and Fabrication of Low-Driving-Voltage Electroabsorption Modulators Operating at 40 Gb/s

In this paper, a design for low-driving-voltage InGaAlAs/InAlAs electroabsorption modulators (EAMs) operating at 40 Gb/s is described. The theoretical calculation clarified that the tensile-strained InGaAlAs/InAlAs multiquantum-well layers with thin wells provide large and steep extinction characteristics. This was experimentally confirmed. We modeled an EAM with a low-loss coplanar waveguide for both the input and output ports and designed an optimized core structure that assures a sufficient extinction ratio and electrical-to-optical bandwidth for 40-Gb/s operation, in terms of well number and core length. A fabricated device driven by a peak-to-peak voltage as low as 1.1 V shows a 3-dB bandwidth of over 50 GHz and an RF extinction ratio of 10 dB. Error-free operation at 40 Gb/s is confirmed.
Immunogenicity of a purified and carrier-complexed streptococcal lipoteichoic acid

Solublie teichoic acid could not stimulate the formation of antibodies either as an aqueous solution or in an emulsion with Freund incomplete adjuvant. However, when given as precipitates with methylated bovine serum albumin, it stimulated strong anti-teichoic acid responses. High levels of anti-teichoic acid antibodies usually resulted in allergic symptoms upon secondary challenge either with immunogenic teichoic acid-methylated bovine albumin complexes or with non-immunogenic soluble teichoic acid. These symptoms suggested anaphylatic shock, but probably also included the formation of complement-consuming immune complexes.
Oral History and al-Nakbah1

Moderating a meeting between Israeli and Palestinian historians in Paris in 1998, [Edward] Said explained in few sentences, and in a very patient voice, to the attentive public at large, and to the less attentive Israeli historians in particular, what a “ historical document ” was . he pointed us to the vitality and signifi cance of oral history in the reconstruction of the past. The most horrifi c aspects of the Nakbah — the dozens of massacres that accompanied the ethnic cleansing — as well as a detailed description of what expulsion had been from the expelled’s point of view, can only be built when such a historiographical position is adopted. 2
