Performance and availability aware regeneration for cloud based multitier applications

Virtual machine technology enables agile system deployments in which software components can be cheaply moved, replicated, and allocated hardware resources in a controlled fashion. This paper examines how these facilities can be used to provide enhanced solutions to the classic problem of ensuring high availability while maintaining performance. By regenerating software components to restore the redundancy of a system whenever failures occur, we achieve improved availability compared to a system with a fixed redundancy level. Moreover, by smartly controlling component placement and resource allocation using information about application control flow and performance predictions from queuing models, we ensure that the resulting performance degradation is minimized. We consider an environment in which a collection of multitier enterprise applications operates across multiple hosts, racks, clusters, and data centers to maximize failure independence. Simulation results show that our proposed approach provides better availability and significantly lower degradation of system response times compared to traditional approaches.
Low expression of nm23-H1 associates with poor survival of nasopharyngeal carcinoma patients

Background: Developing a new reliable prognostic marker to predict the prognosis and supply better and more suitable therapy for patients with nasopharyngeal carcinoma (NPC) is urgent. Therefore, we performed this systematic review of the literature with meta-analysis to clarify and explore the associate expression of nm23-H1 with prognosis of NPC patients. Methods: Literature research in Cochrane Library, PubMed, and EMBASE was performed up to July 2016. Eligible case–control studies of associate expression of nm23-H1 with prognosis of NPC patients were included. Results: Nine studies met our inclusion criteria and were finally included for the analysis, involving 861 participants. Our meta-analysis revealed that the low expression of nm23-H1 in NPC was: RR = 2.13, 95% CI 1.15–3.95 and R = 2.56, 95% CI 2.03–3.22; and poorer overall survival (OS) rate was 3-year OS rate: RR: 0.55; 95% CI: 0.45–0.67 and 5-year OS rate: RR: 0.60; 95% CI: 0.52–0.69. Furthermore, the statistical significance was constant irrespective of different NPC subtypes. Conclusion: The low expression of nm23-H1 is associated with poorer prognosis in patients with NPC, suggesting that it is a prognostic factor and potential biomarker for survival in NPC.
Causal and anti-causal learning in pattern recognition for neuroimaging

Pattern recognition in neuroimaging distinguishes between two types of models: encoding- and decoding models. This distinction is based on the insight that brain state features, that are found to be relevant in an experimental paradigm, carry a different meaning in encoding-than in decoding models. In this paper, we argue that this distinction is not sufficient: Relevant features in encoding- and decoding models carry a different meaning depending on whether they represent causal-or anti-causal relations. We provide a theoretical justification for this argument and conclude that causal inference is essential for interpretation in neuroimaging.
The probabilistic relationship between the assignment and asymmetric traveling salesman problems

We consider the gap between the cost of an optimal assignment in a complete bipartite graph with random edge weights, and the cost of an optimal traveling salesman tour in a complete directed graph with the same edge weights. Using an improved “patching” heuristic, we show that with high probability the gap is $O((\ln n)^2/n)$, and that its expectation is $\Omega(1/n)$. One of the underpinnings of this result is that the largest edge weight in an optimal assignment has expectation $\Theta(\ln n / n)$. A consequence of the small assignment-TSP gap is an $e^{\tilde{O}(\sqrt{n})}$-time algorithm which, with high probability, exactly solves a random asymmetric traveling salesman instance. In addition to the assignment-TSP gap, we also consider the expected gap between the optimal and second-best assignments; it is at least $\Omega(1/n^2)$ and at most $O(\ln n/n^2)$.
On the design of multivariable PID controllers via LMI approach

We study the design problem of multivariable PID controllers which guarantee the stability of the closed loop systems, H/sub 2/ or H/sub /spl infin// performance specifications, or maximum output control requirement, respectively. The basic idea of our method is to transform the problem of PID controller design to that of static output feedback controller design. Algorithms based on an iterative linear matrix inequality technique are developed to find the feedback gains of PID controllers corresponding to the above mentioned four cases.
Rapid Colorimetric Assay for Antimicrobial Susceptibility Testing of Pseudomonas aeruginosa

ABSTRACT A colorimetric assay based on the reduction of a tetrazolium salt {2,3-bis[2-methyloxy-4-nitro-5-sulfophenyl]-2H-tetrazolium-5-carboxanilide (XTT)} for rapidly determining the susceptibility of Pseudomonas aeruginosa isolates to bactericidal antibiotics is described. There was excellent agreement between the tobramycin and ofloxacin MICs determined after 5 h using the XTT assay and after 18 h using conventional methods. The data suggests that an XTT-based assay could provide a useful method for rapidly determining the susceptibility of P. aeruginosa to bactericidal antibiotics.

University of Central Florida at TRECVID 2003

In this paper, we describe the methods for shotboundary detection, story segmentation, and feature extraction developed at the Computer Vision Laboratory, UCF, for TRECVID 2003 forum. To detect shot boundaries in videos, we use a multiresolution color histogram intersection technique in a coarse-to-fine fashion. Detected shot transitions are further classified into abrupt and gradual transitions. We have also developed a method to segment video clips into stories. Our method is based on only visual cues and is useful to separate commercials from the news stories. In addition, we have contributed to the feature extraction task and have developed methods to detect two features, namely, Non-Studio Settings and Weather News. The feature detection also relies on the visual information and exploits the structure of the shot transitions and the common annotations in the news videos. We present our results and its evaluation released by NIST.
Contribution of Social Isolation, Restraint, and Hindlimb Unloading to Changes in Hemodynamic Parameters and Motion Activity in Rats

The most accepted animal model for simulation of the physiological and morphological consequences of microgravity on the cardiovascular system is one of head-down hindlimb unloading. Experimental conditions surrounding this model include not only head-down tilting of rats, but also social and restraint stresses that have their own influences on cardiovascular system function. Here, we studied levels of spontaneous locomotor activity, blood pressure, and heart rate during 14 days under the following experimental conditions: cage control, social isolation in standard rat housing, social isolation in special cages for hindlimb unloading, horizontal attachment (restraint), and head-down hindlimb unloading. General activity and hemodynamic parameters were continuously monitored in conscious rats by telemetry. Heart rate and blood pressure were both evaluated during treadmill running to reveal cardiovascular deconditioning development as a result of unloading. The main findings of our work are that: social isolation and restraint induced persistent physical inactivity, while unloading in rats resulted in initial inactivity followed by normalization and increased locomotion after one week. Moreover, 14 days of hindlimb unloading showed significant elevation of blood pressure and slight elevation of heart rate. Hemodynamic changes in isolated and restrained rats largely reproduced the trends observed during unloading. Finally, we detected no augmentation of tachycardia during moderate exercise in rats after 14 days of unloading. Thus, we concluded that both social isolation and restraint, as an integral part of the model conditions, contribute essentially to cardiovascular reactions during head-down hindlimb unloading, compared to the little changes in the hydrostatic gradient.
University of Groningen Determinants of receiving mental health care for depression in older adults

Background: Major Depressive Disorder (MDD) is common among elderly people. However, it appears that only a minority receives treatment. This study aims to identify and analyse the factors that determine whether elderly people with depressive disorders have contact with health care professionals for mental problems. Method: Cross-sectional analysis of cohort data collected in the Netherlands Study of Depression in Older persons (NESDO) and the Netherlands Study of Depression and Anxiety (NESDA) among 167 respondents aged Z55 with a depressive disorder as indicated by the CIDI. Contacts for mental health problems during the past six months (TiC-P), and indicators of predisposing, enabling, and objective need factors were assessed by interview. Results: Of the total sample, 70% had contact for mental health problems, almost entirely within primary care (62%). The odds of having contact increased with advancing age; for respondents born in the Netherlands; for those who felt less lonely; and for those with a higher household income. Limitations: Our study is based on base-line interviews and thus has a cross-sectional character. Therefore, causal conclusions cannot be drawn. Furthermore, we studied the respondents’ perception whether mental health care was received. Conclusions: The contact rate for mental health problems is high. Health care professionals should be aware that having contact is not associated with a higher objective need, but rather with increasing age, being Dutch-born, being less lonely and having a higher household income. & 2012 Elsevier B.V.

A Novel Weight for Recommendation: Item Quality

The many researches of recommendation technique already have been performed. These techniques were used mostly content-based filtering, collaborative filtering or hybrid filtering approach. They are performed the recommendation using userpsilas rating, user similarity, itempsilas features, user profiles. They consider several features of user and user profiles but they do not consider a quality of items itself. Because they donpsilat be able to efficiently define the quality definition of all item and they donpsilat be able to easily get user feedbacks. To solve the difficulty of the measurement of item quality and apply item quality as a weight to recommendation techniques, we measure item quality through popularity of item and user awareness. And we propose an approach to apply item quality to recommendation.
Attitudes and Social Factors as Predictors of Male Perpetration of Sexual Assault

Previous research has demonstrated a significant association between sexual assault perpetration and hooking up, male peer support for woman abuse, alcohol consumption, and rape myth acceptance (Burt, 1980; Flack, Daubman, Caron, Asadorian, D’Aureli, Gigliotti & Stine, 2007; Schwartz & DeKeseredy, 1997). In the present study, we tested these relationships on the collegiate level by asking male students to indicate levels of male peer support for woman abuse (MPS), acceptance of rape myths (RMA), alcohol consumption, and history of hooking up and sexual assault perpetration during their undergraduate experience. Participants in this study were 200 male Bucknell students (sophomores seniors) who completed an online survey concerning these issues. The overall prevalence rate for some type of sexual assault perpetration was 10.5%. Specific prevalence rates for non-invasive contact, completed rape, and attempted rape were 5.5%, 2.0%, and 5.0%, respectively. Sexual assault perpetration was positively correlated with MPS and alcohol consumption but not with RMA. Sexual assault was perpetrated most frequently during acquaintance hook ups. These findings demonstrate direct, significant relationships between sexual assault perpetration, alcohol abuse, different types of hooking up, and rape-supportive attitudes, and an association between perpetration and MPS that requires further elaboration.
Anti-Jo-1 antisynthetase syndrome.

OBJECTIVE Given a lack of population-based studies, we report an epidemiological-clinic study of anti-Jo-1 antisynthetase syndrome (ASS). PATIENTS AND METHODS To study a retrospective cohort of a single-center from 1980 to 2010. Clinical-laboratory and demographic data were obtained from medical files. All patients fulfilled the Bohan and Peter criteria (1975) and presented anti-Jo-1, articular, muscle and lung involvement. Eighteen patients with anti-Jo-1 ASS were analyzed. RESULTS The mean age at disease onset was 39.9 ± 15.7 years and average disease duration was 9.7 ± 7.0 years. All subjects were white, and 94.4% were female. Constitutional symptoms occurred in 50 % of cases. There was cutaneous and gastrointestinal tract involvement in 66.6% and 55.6% of cases, respectively. No cases manifested neurologic or cardiac involvement. Half of the patients showed incipient pneumopathy, ground-glass opacities and basal pulmonary fibrosis. There was one case of tuberculosis, three of herpes zoster and one of non-Hodgkin lymphoma. One death occurred due to sepsis shock (hospital bronchopneumonia). All patients received prednisone (1mg/kg/day) and 12 (66.7%) participants received methyl prednisolone pulse therapy (1g/day, 3 days). Various immunosuppressants were used as corticosteroid tapers, depending on tolerance, side effects and/or refractoriness. Although disease relapse (clinical and/or laboratory) occurred in 87.5% of cases, 12 out of 16 patients (75%) were in disease remission at study endpoint. CONCLUSION In the present study, almost all patients were white females and the disease relapse rate was high.
Role of the Black Grandmother in the Racial Socialization of their Biracial Grandchildren

ABSTRACT The current study was conducted with seven Black grandmothers who have a biracial (Black and White) grandchild or grandchildren examining their role in the racial socialization process of their grandchild or grandchildren. Racial socialization is defined as how these grandchildren of biracial parentage came to understand their blackness. The following criteria had to be met; born before 1975 as this would ensure the grandmothers experienced the 70s. Black pride movement and they need to have contact with the identified grandchild. Qualitative methods with a phenomenological lens were used. The results revealed the perspective and methods they exercised in racially socializing their biracial grandchildren fell into eight themes. The themes that emerged were community influence, spirituality, social adjustment, feelings toward “the other,” social perception, cultural indoctrination, grandma’s burden, and the road ahead. Although each grandmother had a different journey and the “why” behind viewpoints varied, their conclusion regarding the proper racial socialization of their biracial grandchildren was to socialize them, as Black was unanimous.
Towards mobile and touchless fingerprint verification

Touchless finger detection for the biometric fingerprint verification/identification process with mobile devices is considered in this paper. Fingerprint capturing is based on a camera system with bright-field illumination. For finger detection, a machine learning based algorithm with Aggregated Channel Features (ACFs) and a skin-color based finger segmentation with a geometric shape based approach for fingertip detection are considered, respectively. Results demonstrate the performance of both algorithms.
Predictive Modeling of Channel Potential in 3-D NAND Flash Memory

For the first time, this brief analyzes the channel potential and capacitance in channel-stack type 3-D NAND flash memory structure. In addition, the effects of geometrical parameters on 3-D NAND flash design with gate-all-around and double-gate devices are studied. The model can be incorporated into a compact circuit model for 3-D NAND flash design optimization.
A Static Approach to Prioritizing JUnit Test Cases

Test case prioritization is used in regression testing to schedule the execution order of test cases so as to expose faults earlier in testing. Over the past few years, many test case prioritization techniques have been proposed in the literature. Most of these techniques require data on dynamic execution in the form of code coverage information for test cases. However, the collection of dynamic code coverage information on test cases has several associated drawbacks including cost increases and reduction in prioritization precision. In this paper, we propose an approach to prioritizing test cases in the absence of coverage information that operates on Java programs tested under the JUnit framework-an increasingly popular class of systems. Our approach, JUnit test case Prioritization Techniques operating in the Absence of coverage information (JUPTA), analyzes the static call graphs of JUnit test cases and the program under test to estimate the ability of each test case to achieve code coverage, and then schedules the order of these test cases based on those estimates. To evaluate the effectiveness of JUPTA, we conducted an empirical study on 19 versions of four Java programs ranging from 2K-80K lines of code, and compared several variants of JUPTA with three control techniques, and several other existing dynamic coverage-based test case prioritization techniques, assessing the abilities of the techniques to increase the rate of fault detection of test suites. Our results show that the test suites constructed by JUPTA are more effective than those in random and untreated test orders in terms of fault-detection effectiveness. Although the test suites constructed by dynamic coverage-based techniques retain fault-detection effectiveness advantages, the fault-detection effectiveness of the test suites constructed by JUPTA is close to that of the test suites constructed by those techniques, and the fault-detection effectiveness of the test suites constructed by some of JUPTA's variants is better than that of the test suites constructed by several of those techniques.
Applications of Ecobehavioral Analysis to the Study of Transitions across Early Education Settings.

This article describes the way ecobehavioral analysis has been applied to the study of transitions between special preschool and regular kindergarten settings. After an introduction to the concept of ecobehavior analysis, we describe two instruments that have been developed for evaluating ecobehavioral interactions within early education classrooms. The first, Ecobehavioral System for the Complex Assessment of Preschool Environments - ESCAPE, has been used to contrast special preschool and regular kindergarten environments, student behavior within those settings, and teacher and student behaviors that occur within specific ecological contexts within those settings. The second instrument, Assessment Code/Checklist for Evaluating Survival SkillsACCESS, has been used to compare some specific teacher-student interactions across the two settings that are critical for student success in regular classrooms. The paper concludes with a discussion of the implications of these types of analyses for the study of children's transition from special preschools to kindergarten.
Mobility of moose—comparing the effects of wolf predation risk, reproductive status, and seasonality

Abstract In a predator–prey system, prey species may adapt to the presence of predators with behavioral changes such as increased vigilance, shifting habitats, or changes in their mobility. In North America, moose (Alces alces) have shown behavioral adaptations to presence of predators, but such antipredator behavioral responses have not yet been found in Scandinavian moose in response to the recolonization of wolves (Canis lupus). We studied travel speed and direction of movement of GPS‐collared female moose (n = 26) in relation to spatiotemporal differences in wolf predation risk, reproductive status, and time of year. Travel speed was highest during the calving (May–July) and postcalving (August–October) seasons and was lower for females with calves than females without calves. Similarly, time of year and reproductive status affected the direction of movement, as more concentrated movement was observed for females with calves at heel, during the calving season. We did not find support for that wolf predation risk was an important factor affecting moose travel speed or direction of movement. Likely causal factors for the weak effect of wolf predation risk on mobility of moose include high moose‐to‐wolf ratio and intensive hunter harvest of the moose population during the past century.
Deficits in speed discrimination following lesions of the lateral suprasylvian cortex in the cat

Abstract We examined the role of the lateral suprasylvian (LS) cortex in motion perception by testing the ability of three cats to detect moving targets and to discriminate differences in stimulus direction and speed before and after making bilateral ibotenic acid lesions in LS. The lesions had little or no effect on contrast sensitivity for detecting moving sinusoidal gratings. Moreover, we found no deficits in discriminating opposite directions of motion: the cats discriminated grating directions at threshold contrasts. All three cats, however, showed permanent deficits in discriminating differences in speed and in flicker rate. The deficits were most pronounced at higher temporal and spatial frequencies and at lower contrasts. This result suggests that LS plays an important role in the analysis of stimulus speed. It appears that information needed for discriminating opposite directions of motion may be signalled by visual areas outside LS.
Link-based Active Learning

Supervised and semi-supervised data mining techniques require labeled data. However, labeling examples is costly for many real-world applications. To address this problem, active learning techniques have been developed to guide the labeling process in an effort to minimize the amount of labeled data without sacrificing much from the quality of the learned models. Yet, most of the active learning methods to date have remained relatively agnostic to the rich structure offered by network data, often ignoring the relationships between the nodes of a network. On the other hand, the relational learning community has shown that the relationships can be very informative for various prediction tasks. In this paper, we propose different ways of adapting existing active learning work to network data while utilizing links to select better examples to label.
