Data and process abstractions for cloud computing

Applying suitable application models is essential to achieve efficient execution of the applications, effective development process and assure application portability and reusability. We observe that execution environments and the cloud environment in particular, lack of tools that would make it more available from a programmer perspective. Complexity and variety of libraries and authentication methods do not correspond with simplistic functionality of those services. We approach this issue at several fields - workflow systems, domain specific languages and cloud computing. Our work focus on two points, optimizing existing application models by supplementing them with additional tools and providing new features, and develop new models that are based on our research on applications in the cloud environment.
Palmar Skin Blood Flow and Temperature Responses Throughout Endoscopic Sympathectomy

Thoracic surgical sympathectomy is often performed to treat primary palmar and axillary hyperhidrosis. An increase in palmar skin temperature is frequently used to identify the success of the procedure. Because changes in palmar skin temperature occur secondary to changes in skin blood flow, the objective of this study was to test the hypothesis that monitoring palmar skin blood flow would provide greater temporal resolution relative to monitoring palmar skin temperature. In 11 patients with palmar and/or axillary hyperhidrosis, we measured palmar skin temperature and blood flow (via laser Doppler flowmetry) throughout the sympathectomy procedure. Five minutes after the initial cautery, skin blood flow increased from 48 ± 7 perfusion units to 121 ± 17 perfusion units (P < 0.001), whereas no significant change in temperature was observed (31.0°C ± 0.5°C to 31.3°C ± 0.5°C; P > 0.05). The time required to reach peak skin blood flow (22 ± 3 min) was significantly less than the time required to reach peak skin temperature (34 ± 0.3 min; P < 0.001). Finally at 5, 10, and 15 min after the initial cautery, skin blood flow increased to a larger percentage of the total increase in skin blood flow relative skin temperature (all P < 0.006). These data suggest that monitoring skin blood flow provides greater temporal resolution when compared with monitoring skin temperature during thoracic sympathectomy. However, the initial cautery of the parietal pleura over the ganglion may result in increases in skin blood flow before physical disruption of the ganglion. This occurrence may limit the utility of skin blood-flow measurements in identifying the success of the procedure.
Exploring the heterogeneous design space for both performance and reliability

As we move into a new era of heterogeneous multi-core systems, our ability to tune the performance and understand the reliability of both hardware and software becomes more challenging. Given the multiplicity of different design trade-offs in hardware and software, and the rate of introduction of new architectures and hardware/-software features, it becomes difficult to properly model emerging heterogeneous platforms. In this paper we present a new methodology to address these challenges in a flexible and extensible framework. We describe the design of a framework that supports a range of heterogeneous devices to be evaluated based on different performance/reliability criteria. We address heterogeneity both in hardware and software, providing a flexible framework that can be easily adapted and extended as new elements in the SoC stack continue to evolve. Our framework enables modeling at different levels of abstraction and interfaces to existing tools to compose hybrid modeling environments. We also consider the role of software, providing a flexible and modifiable compiler stack based on LLVM. We provide examples that highlight both the flexibility of this framework and demonstrate the utility of the tools.
Korean State-Trait Anxiety Inventory Application Study in Middle and High School Students

Objectives：This study aimed to investigate the validity and standardize the Spielberger State-Trait Anxiety Inventory (STAI) in middle and high school students and find the factors which influenced their anxiety. Methods：1,033 middle and high school students were selected randomly from 7 regions around the country. The State-Trait Anxiety Inventory (STAI) was applied in all subjects and the Beck Anxiety Inventory (BAI) was applied with it to calculate the coexistence validity. To find the causes of adolescent anxiety, Beck Depression Inventory (BDI), Subjective Happiness Scale, The Satisfaction With Life Scale, Rosenberg Self-Esteem Scale (RES), Parent-Adolescent communication family inventories, In family social scene were all applied and correlation with STAI was investigated. Results：Reliability issues, such as internal coherence, the coherence between specific phobia and anxiety state were satisfactory and the coexistence validity with BAI was high. The result of factor analysis shows that factor structures were similar to previous studies. High school students showed higher anxiety levels than middle school students, and girls higher than boys. For socio-economical factors, poverty and poor grades related to higher anxiety. Among psychological factors, happiness and selfesteem showed high correlation with anxiety. Conclusion：The State-Trait Anxiety Inventory (STAI) showed high validity and reliability in middle and high school students and proved itself a reliable scale. When treating their anxiety, age, sex, socio-economical and psychological factors should all be considered.
Antenna pairing for space-frequency block codes in edge-excited distributed antenna systems

Space-frequency block codes (SFBC) combined with frequency switched transmit diversity (FSTD) is used in the downlink of 3GPP LTE system, where all transmit antennas are collocated at eNodeBs. However, all transmit antennas serving a cell are distributed at the cell edge in edge-excited distributed antenna systems. The performance of SFBC is greatly affected by the different large scale fading from different remote antenna units. In this paper, we investigate the tradeoff between the coding gain and average receive SNR of SFBC in DAS layout and propose to set apart the two antennas of SFBC transmission as far as possible. The optimal antenna pairing schemes in the edge-excited DAS cells compatible with 3GPP LTE system are those with the maximized average distance of SFBC transmission. According to the system level simulations in multicell environment, the 5% outage spectrum efficiency and average throughput per cell of SFBC transmission are improved by as much as 21.8% and 11.6% respectively in DAS3 cells,compared with those in LTE system. The DAS6 cells achieve even high gains in outage spectrum efficiency by 123.6% and average throughput per cell by 22.5%.
Mimovirus: a Novel Form of Vaccine That Induces Hepatitis B Virus-Specific Cytotoxic T-Lymphocyte Responses In Vivo

ABSTRACT CD8+ cytotoxic T lymphocytes (CTLs) are now recognized as important mediators of immunity against intracellular pathogens, including human immunodeficiency virus and tumors. How to efficiently evoke antigen-specific CTL responses in vivo has become a crucial problem in the development of modern vaccines. Here, we developed a completely novel CTL vaccine—mimovirus, which is a kind of virus-size particulate antigen delivery system. It was formed by the self-assembly of a cationic peptide containing 18 lysines and a CTL-epitope peptide of HBsAg28-39, with a plasmid encoding mouse interleukin-12 (IL-12) through electrostatic interactions. We examined the formation of mimovirus by DNA retardation assay, DNase I protection assay, and transmission electron microscopy and demonstrated that mimovirus could efficiently transfer the plasmid encoding IL-12 into mammalian cells such as P815 cells in vitro. Furthermore, it was proved that mimovirus could induce an HBsAg28-39-specific CTL response in vivo. Considering its effectiveness, flexibility, and defined composition, mimovirus is potentially a novel system for vaccination against intracellular pathogens and tumors.
Study of the Penetration Bias of ENVISAT Altimeter Observations over Antarctica in Comparison to ICESat Observations

The aim of this article is to characterize the penetration bias of the ENVIronmental SATellite (ENVISAT) radar altimeter over the Antarctic ice sheet through comparison with the more accurate measurements of the Ice, Cloud and land Elevation Satellite (ICESat) altimeter at crossover points. We studied the difference between ENVISAT and ICESat fluctuations over six years. We observed the same patterns between the leading edge width and the elevation difference. Both parameters are linked, and the major bias is due to the lengthening of the leading edge width due to the radar penetration. We show that the elevation difference between both altimeters and the leading edge width are linearly well-linked with a 0.8 Pearson correlation coefficient, whereas the slope effect over the coasts is difficult to analyze. When we analyze each crossover point temporal evolution locally, the linear correlation between the leading edge width and the elevation difference is between −0.6 and −1. Fitting a linear model between them, we find a reliability index greater than 0.7 for the Antarctic Plateau and Dronning Maud Land, which confirms that the penetration effect has a linear influence on the retrieved height. Moreover, we present results from SARAL/AltiKa (launched in February 2013) that confirm SARAL/AltiKa accuracy and the promising information it will provide.
Exchange Reactions in the Ca-Mg-Na-Montmorillonite System

The exchange reactions of Na, Ca and Mg on montmorillonite are revisited employing recently developed analytical and theoretical approaches. The fractional adsorption of the cations has been determined by displacing them from the adsorbed state in one step, using a low concentration of an organic cation of large binding affinity. The analysis of displaced and solution cations employed inductively coupled plasma emission spectrometry. An adsorption model was employed in the analysis of the data. The procedure consists of solving the electrostatic Gouy-Chapman equations and calculating adsorbed amounts of the cations as the sum of the cations residing in the double layer region, and the cations chemically bound to the surface, in a closed system. The model also accounts explicitly for cation complexation in solution. Thus the calculations also considered the adsorption of CaCl+ and MgCl+, which eliminated the apparent increase of the cation exchange capacity (CEC) with divalent cation concentration. The model could explain and yield predictions for our measured adsorbed amounts as well as previously published data, in the binary and ternary systems of Ca/Mg/Na, provided that the fraction of surface sites occupied by calcium did not exceed 0.4. For a larger coverage of surface sites by calcium, a fit of the experimental data required an order of magnitude increase in the binding coefficients of the divalent cations in the binary system Ca/Na and in the ternary system Ca/Mg/Na.
Evidence for a Proton–Protein Symport Mechanism in the Anthrax Toxin Channel

The toxin produced by Bacillus anthracis, the causative agent of anthrax, is composed of three proteins: a translocase heptameric channel, (PA63)7, formed from protective antigen (PA), which allows the other two proteins, lethal and edema factors (LF and EF), to translocate across a host cell's endosomal membrane, disrupting cellular homeostasis. It has been shown that (PA63)7 incorporated into planar phospholipid bilayer membranes forms a channel capable of transporting LF and EF. Protein translocation through the channel is driven by a proton electrochemical potential gradient on a time scale of seconds. A paradoxical aspect of this is that although LFN (the N-terminal 263 residues of LF), on which most of our experiments were performed, has a net negative charge, it is driven through the channel by a cis-positive voltage. We have explained this by claiming that the (PA63)7 channel strongly disfavors the entry of negatively charged residues on proteins to be translocated, and hence the aspartates and glutamates on LFN enter protonated (i.e., neutralized). Therefore, the translocated species is positively charged. Upon exiting the channel, the protons that were picked up from the cis solution are released into the trans solution, thereby making this a proton–protein symporter. Here, we provide further evidence of such a mechanism by showing that if only one SO3−, which is essentially not titratable, is introduced at most positions in LFN, through the reaction of an introduced cysteine residue at those positions with 2-sulfonato-ethyl-methanethiosulfonate, voltage-driven LFN translocation is drastically inhibited. We also find that a site that disfavors the entry of negatively charged residues into the (PA63)7 channel resides at or near its Φ-clamp, the ring of seven phenylalanines near the channel's entrance.
Towards affective state modeling in narrative and conversational settings

We carry out two studies on affective state modeling for communication settings that involve unilateral intent on the part of one participant (the evoker) to shift the affective state of another participant (the experiencer). The first investigates viewer response in a narrative setting using a corpus of documentaries annotated with viewer-reported narrative peaks. The second investigates affective triggers in a conversational setting using a corpus of recorded interactions, annotated with continuous affective ratings, between a human interlocutor and an emotionally colored agent. In each case, we build a "one-sided" model using indicators derived from the speech of one participant. Our classification experiments confirm the viability of our models and provide insight into useful features.
Complementary and alternative medicine in asthma: do they work?

OBJECTIVE An increasing number of patients with asthma are attracted by complementary and alternative medicine (CAM). Therefore, it is of importance that scientific evidence about the efficacy of this type of therapy is regarded. METHOD We searched the electronic databases Medline, Embase and the Cochrane Library for controlled trials and systematic reviews to evaluate the evidence of the most popular alternative therapies, i.e. acupuncture, homeopathy, breathing techniques, herbal and nutritional therapies. RESULTS Claims that acupuncture is effective for the treatment of asthma are not based on well-performed clinical trials. The role of homeopathy in the treatment of asthma needs further evaluation. Breathing techniques, e.g. improved control of breathing by yoga, may contribute to the control of asthma symptoms, but due to the small number of controlled trials and due to the small number of patients it is not possible to make firm judgments. Herbal remedies cannot be recommended based on the available evidence. Recommendations for a diet high in vitamin C and marine fatty acids are not harmful, but evidence for clinically meaningful effects are scant. CONCLUSION Up to now evidence is lacking that alternative forms of medicine are more effective than placebo in asthma. However, lack of evidence does not always mean that treatment is ineffective, but it could mean that effectiveness has not been adequately investigated. High quality research as in conventional therapy should be fostered in complementary medicine.
Comparison of bacterial and fungal adherence to vaginal exfoliated epithelial cells and human vaginal epithelial tissue culture cells

The adherence of four bacterial species and Candida albicans to a new in vitro tissue culture model of human vaginal stratified squamous epithelium was investigated and compared with in vitro adherence to vaginal exfoliated cells. Gardnerella vaginalis, group B streptococci, Lactobacillus sp. , and C. albicans adhered well to both exfoliated and tissue culture cells. Similarly, a piliated fecal isolate of Escherichia coli, but not a nonpiliated vaginal isolate of E. coli, adhered well to both cell types. Adherence of the piliated E. coli was markedly inhibited by preincubation of bacteria with D-mannose. No inhibition of adherence by D-mannose of G. vaginalis, nonpiliated E. coli, and C. albicans was demonstrated. Scanning electron microscopy of tissue cultures showed nonuniform distribution of adherent microorganisms with diminished adherence in areas of active mitosis and proliferation and increased adherence to mature flat cells, often in the process of desquamation.
[Is 'attention' important for the results of dementia screening? Relation among Digit Span Test, CST amd ADS in elderly patients].

This study focused on the relationship between attention and dementia screening test performance, using the adapted Wechsler's Digit Span test for elderly patients, the Cognitive Screening Test (CST) and the Amsterdam Dementia Screening Test (ADS6). Participants were dementia patients and psychiatric patients (n = 147). In both groups no floor-effect was found on the Digit Span test. Principal components analysis showed that CST and ADS6-scores had relatively high loadings on one factor, in contrast to digit span scores that loaded on a second factor. On average, psychiatric patients did hardly worse than normal controls. Attention deficits were more apparent in dementia patients. Considering a maximum of r = . 41, these more or less subtle deficits were only moderately related to dementia screening test performance. It is concluded that the adapted Digit Span test is suitable for measuring attention deficits in elderly patients. However, Digit Span predicts performance on dementia screening test only to a modest degree.
The reliability of wireless backhaul mesh networks

When planning the structure of a backhaul mesh network for public access, it is common to introduce redundant nodes in the mesh network. These are called redundant, because they do not increase the network capacity under normal operation, due to the shortest-path metric of the routing protocol. Instead, their sole purpose is to increase the network reliability by providing failover links when a link in the shortest-path fails. This paper shows how to estimate the additional network reliability that results from introducing a redundant node. The best location of a redundant node, i.e. where to locate the node in order to maximise the additional network reliability, can also be found.
Climatic niche conservatism and ecological opportunity in the explosive radiation of arvicoline rodents (Arvicolinae, Cricetidae)

Climatic niche conservatism shapes patterns of diversity in many taxonomic groups, while ecological opportunity (EO) can trigger rapid speciation that is less constrained by the amount of time a lineage has occupied a given habitat. These two processes are well studied, but limited research has considered their joint and relative roles in shaping diversity patterns. We characterized climatic and biogeographic variables for 102 species of arvicoline rodents (Arvicolinae, Cricetidae), testing the effects of climatic niche conservatism and EO on arvicoline diversification as lineages transitioned between biogeographic regions. We found that the amount of time a lineage has occupied a precipitation niche is positively correlated with diversity along a precipitation gradient, suggesting climatic niche conservatism. In contrast, shift in diversification rate explained diversity patterns along a temperature gradient. Our results suggest that an indirect relationship exists between temperature and diversification that is associated with EO as arvicoline rodents colonized warm Palearctic environments. Climatic niche conservatism alone did not fully explain diversity patterns under density‐dependence, highlighting the additional importance of EO‐related processes in promoting the explosive radiation in arvicoline rodents and shaping diversity pattern among biogeographic regions and along climatic gradients.
Mind-wandering:Phenomenon,Mechanism and Significance

Mind-wandering is involuntary conscious experience arising internally,and it's a significant part of "stream of consciousness". The phenomenon of mind-wandering suggests the significance of non-perceptual consciousness in human consciousness system,and the significance of ongoing unconscious processing for individual survival.The research about mind-wandering is becoming the live topic in psychology and cognitive neuroscience.After reviewing the studies about the content of mind-wandering,its relation with emotion and its neural correlates,we discussed the possible mechanism of mind-wandering and its adaptive function.At the end of the paper,we summarised the deficiency of the existing studies,such as the ambiguity in the definition of mind-wandering and the methodological limitations,and the future study trends was developed.
A new technique for low-cost phase noise production testing from 1-bit signal acquisition

This paper introduces a new technique for low-cost phase noise production testing from 1-bit signal acquisition. The technique relies on reconstruction of phase fluctuation from the binary vector captured by a digital ATE channel. A dedicated post-processing algorithm is developed that permits phase noise evaluation from the analysis of the reconstructed time-domain phase fluctuation. The technique is validated through hardware measurements and results demonstrate an excellent agreement with conventional phase noise measurements.
Complete Obliteration of the Left Atrial Appendage an Analysis of Epicardial Excision and Novel Pericardial Patch Exclusion

Objective Conventional epicardial excision is believed to be the most effective method of surgically obliterating the left atrial appendage (LAA), although incomplete resection and residual LAA volume may undermine its effectiveness. We sought to compare the impact of conventional epicardial excision with a novel LAA pericardial patch exclusion on residual LAA volume. Methods We performed LAA obliteration using pericardial patch exclusion, followed by conventional epicardial excision, in 27 cadaveric hearts. After each procedure, residual LAA volume was measured by two different techniques and compared with baseline volume. There was no difference in baseline LAA volume between each procedure. Results Procedural success was achieved in all hearts. Conventional epicardial excision left a residual LAA volume of 0.95 mL (24%), as compared with pericardial patch exclusion, which left a residual volume of 0.17 mL (4%, P = 0.0001). Further analysis of fixed and fresh hearts showed that reduction of LAA volume was more pronounced in the fresh hearts, suggesting effectiveness in live patients. Neither technique resulted in any significant change in the endocardial shape of the LAA orifice or injury to the circumflex artery. Conclusions Conventional epicardial excision of the LAA results in significantly more residual LAA volume, which may have important implications in persistent stroke risk. Pericardial patch exclusion seems to achieve near-total elimination of the LAA and may be a superior surgical option.
