Concurrent Negotiation and Coordination for Grid Resource Coallocation

Bolstering resource coallocation is essential for realizing the Grid vision, because computationally intensive applications often require multiple computing resources from different administrative domains. Given that resource providers and consumers may have different requirements, successfully obtaining commitments through concurrent negotiations with multiple resource providers to simultaneously access several resources is a very challenging task for consumers. The impetus of this paper is that it is one of the earliest works that consider a concurrent negotiation mechanism for Grid resource coallocation. The concurrent negotiation mechanism is designed for 1) managing (de)commitment of contracts through one-to-many negotiations and 2) coordination of multiple concurrent one-to-many negotiations between a consumer and multiple resource providers. The novel contributions of this paper are devising 1) a utility-oriented coordination (UOC) strategy, 2) three classes of commitment management strategies (CMSs) for concurrent negotiation, and 3) the negotiation protocols of consumers and providers. Implementing these ideas in a testbed, three series of experiments were carried out in a variety of settings to compare the following: 1) the CMSs in this paper with the work of others in a single one-to-many negotiation environment for one resource where decommitment is allowed for both provider and consumer agents; 2) the performance of the three classes of CMSs in different resource market types; and 3) the UOC strategy with the work of others [e.g., the patient coordination strategy (PCS )] for coordinating multiple concurrent negotiations. Empirical results show the following: 1) the UOC strategy achieved higher utility, faster negotiation speed, and higher success rates than PCS for different resource market types; and 2) the CMS in this paper achieved higher final utility than the CMS in other works. Additionally, the properties of the three classes of CMSs in different kinds of resource markets are also verified.
How automated agents treat humans and other automated agents in situations of inequity: an experimental study

This paper explores the question of how agent designers perceive and treat their agent's opponents. In particular, it examines the influence of the opponent's identity (human vs. automated agent) in negotiations. We empirically demonstrate that when people interact spontaneously they treat human opponents differently than automated agents in the context of equity and fairness considerations. However, these difference vanish when people design and implement agents that will interact on their behalf. Nevertheless, the commitment of the agents to honor agreements with people is higher than their commitment to other agents. In the experiments, which comprised 147 computer science students, we used the Colored Trails game as the negotiation environment. We suggest possible explanations for the relationships among online players, agent designers, human opponents and automated opponents.
What native speaker judgments tell us about the grammaticalization of a progressive aspectual marker in Dutch

Abstract This paper focuses on native speaker judgments of a construction in Dutch that functions as a progressive aspectual marker (aan het X zijn, referred to as aan het-construction) and represents an event as in progression at the time of speech. The method was chosen in order to investigate how native speakers assess the scope and conditions of use of a construction which is in the process of grammaticalization. It allows for the inclusion of a large group of participants of different age groups and an investigation of potential age-related differences. The study systematically covers a range of temporal variables that were shown to be relevant in elicitation and corpus-based studies on the grammaticalization of progressive aspect constructions. The results provide insights into the selectional preferences and constraints of the aan het-construction in contemporary Dutch, as judged by native speakers, and the extent to which they correlate with production tasks.
Field-incidence transmission of treated orthotropic and laminated composite panels

In an effort to improve understanding of the phenomenon of noise transmission through the sidewalls of an aircraft fuselage, an analytical model was developed for the field incidence transmission loss of an orthotropic or laminated composite infinite panel with layers of various noise insulation treatments. The model allows for four types of treatments, impervious limp septa, orthotropic trim panels, porous blankets, and air spaces, while it also takes into account the effects of forward speed. Agreement between the model and transmission loss data for treated panels is seen to be fairly good overall. In comparison with transmission loss data for untreated composite panels, excellent agreement occurred.
Does breastfeeding influence risk of type 2 diabetes in later life? A quantitative analysis of published evidence.

BACKGROUND Observational evidence suggests that having been breastfed in infancy may reduce the prevalence of type 2 diabetes in later life. OBJECTIVE The objective was to examine the influence of initial breastfeeding on type 2 diabetes and blood glucose and insulin concentrations. DESIGN A systematic review of published studies identified 1010 reports; 23 examined the relation between infant feeding and type 2 diabetes in later life or risk factors for diabetes. Risk factors in infants were examined separately from those in children and adults. All estimates were pooled by using fixed-effect models; differences <0 and ratios <1 imply a beneficial effect of breastfeeding. RESULTS Subjects who were breastfed had a lower risk of type 2 diabetes in later life than did those who were formula fed (7 studies; 76 744 subjects; odds ratio: 0.61; 95% CI: 0.44, 0.85; P = 0.003). Children and adults without diabetes who had been breastfed had marginally lower fasting insulin concentrations than did those who were formula fed (6 studies; 4800 subjects; percentage difference: -3%; 95% CI: -8%, 1%; P = 0.13); no significant difference in fasting glucose concentrations was observed. Breastfed infants had lower mean preprandial blood glucose (12 studies; 560 subjects; mean difference: -0.17 mmol/L; 95% CI: -0.28, -0.05 mmol/L; P = 0.005) and insulin (7 studies; 291 subjects; mean difference: -2.86 pmol/L; 95% CI: -5.76, 0.04 pmol/L; P = 0.054) concentrations than did those who were formula fed. CONCLUSION Breastfeeding in infancy is associated with a reduced risk of type 2 diabetes, with marginally lower insulin concentrations in later life, and with lower blood glucose and serum insulin concentrations in infancy.
Posttraumatic stress disorder and psychiatric comorbidity among detained youths.

OBJECTIVE This study examined the prevalence of posttraumatic stress disorder (PTSD) and comorbid psychiatric disorders among juvenile detainees. METHODS The sample consisted of a stratified random sample of 898 youths aged ten to 18 years who were arrested and detained in Chicago. RESULTS Among participants with PTSD, 93% had at least one comorbid psychiatric disorder; however, among those without PTSD, 64% had at least one comorbid psychiatric disorder. Over half (54%) of the participants with PTSD had two or more types of comorbid disorders--that is, affective, anxiety, behavioral, or substance use disorders--and 11% had all four types of comorbid disorders. Among males, having any psychiatric diagnosis significantly increased the odds of having comorbid PTSD. Among females, alcohol use disorder and both alcohol and drug use disorders significantly increased the odds of having PTSD. No significant difference in prevalence rates of PTSD was found between males and females with specific psychiatric disorders. The prevalence of any comorbid psychiatric disorder was significantly greater for males with PTSD than that for females with PTSD (OR=3.4, CI=1.1-10.6, p<.05). CONCLUSIONS Detection of comorbid PTSD among detained youths must be improved. PTSD is often missed because traumatic experiences are rarely included in standard screens or volunteered by patients. When planning treatment, clinicians must consider ramifications of comorbid PTSD.
Evaluation of Low Temperature Performance for Diatomite Modified Asphalt Mixture

According to the low temperature disease on asphalt pavement in the areas of cold and large temperature difference between day and night, conventional index test and low temperature bending creep test were used to analyze the influence of diatomite dosage on the low temperature performance of diatomite modified asphalt, and the mixture’s low temperature bending test was applied for verification. Test results show that after diatomite’s addition into asphalt, equivalent brittle point reduces significantly, ductility test cannot estimate low temperature performance very well, stiffness modulus increases and relaxation ability decreases; meanwhile, peak value of stiffness modulus and strain energy of asphalt mixture can be found, the low temperature crack resistance is enhanced; optimum dosage of diatomite is 13%. So, the low temperature performance evaluation method of diatomite modified asphalt mixture through BBR’s low temperature performance evaluation on diatomite modified asphalt remains to be discussed.
Food-Related Odors Activate Dopaminergic Brain Areas

Food-associated cues of different sensory categories have often been shown to be a potent elicitor of cerebral activity in brain reward circuits. Smells influence and modify the hedonic qualities of eating experience, and in contrast to smells not associated with food, perception of food-associated odors may activate dopaminergic brain areas. In this study, we aimed to verify previous findings related to the rewarding value of food-associated odors by means of an fMRI design involving carefully preselected odors of edible and non-edible substances. We compared activations generated by three food and three non-food odorants matching in terms of intensity, pleasantness and trigeminal qualities. We observed that for our mixed sample of 30 hungry and satiated participants, food odors generated significantly higher activation in the anterior cingulate cortex (right and left), insula (right), and putamen (right) than non-food odors. Among hungry subjects, regardless of the odor type, we found significant activation in the ventral tegmental area in response to olfactory stimulation. As our stimuli were matched in terms of various perceptual qualities, this result suggests that edibility of an odor source indeed generates specific activation in dopaminergic brain areas.
Motivation in health behavior: Measurement, antecedents, and correlates

Additional reliability, validity, and information on health behavior correlates for a recently developed measure of intrinsic motivation in health behavior are reported. A randomly selected sample of 379 elders responded to a structured interview containing the Health Self-determinism Index (HSDI) and other relevant variables. The overall reliability of the HSDI was supported with an alpha coefficient of 0.78. The multidimensionality of the instrument was reconfirmed through principal components analysis, and factor invariance across study samples was established. The total HSDI and subscale scores were associated with the practice of selected life-style behaviors. The homogeneity of the sample raises significant considerations relative to contextual item sensitivity and sample-induced response tendencies.
Influence of lubrication on through thickness texture of ferritically hot rolled interstitial free steel

Over recent years, attention has been focused on the development of ferritically hot rolled steels, despite the inherently low drawability attributed to the formation of a (110) texture just below the strip surface. This texture, which cannot be removed by further processing, prevents the formation of the (222) compression texture necessary for good drawability. However, the present programme demonstrates that the use of interstitial free (IF) steels, coupled with the selection of ester oils for rolling lubrication, suppresses the (110) shear texture to satisfy the (222)/(200) > 1 requirements for good drawability. In contrast, while mineral oil reduces frictional conditions in the roll gap, no improvement in through thickness texture formation is found during ferritic hot rolling.
Chromosome breakage and cellular death are induced in oral epithelial cells of hairdressers: a preliminary study

The aim of the present study was to comparatively evaluate genomic damage (micronucleus) and cellular death (pyknosis, karyolysis and karyorrhexis) in exfoliated oral mucosa cells from hairdressers using two different anatomic buccal sites: cheek mucosa and lateral border of the tongue. A total of 28 hairdressers and 30 health controls (non-exposed individuals) were included in this setting. Individuals had epithelial cells from the cheek and lateral border of the tongue mechanically exfoliated, placed in fixative and dropped in clean slides that were checked for the previously mentioned nuclear phenotypes. The results pointed out statistically significant differences (p < 0.05) of micronucleated oral mucosa cells from hairdressers in the lateral border of the tongue. Exposure to hair dyes caused an increase of other nuclear alterations closely related to cytotoxicity, such as karrhyorexis, pyknosis and karyolysis in both the oral sites evaluated. In summary, these data indicate that hairdressers are occupationally exposed to agents that are genotoxic and cytotoxic. It seems that the lateral border of the tongue is a more sensitive site to the genotoxic and cytotoxic effects of hair dyes.
Competency-based medical education: An overview and application in pharmacology

Competency-based medical education (CBME) is gaining momentum across the globe. The Medical Council of India has described the basic competencies required of an Indian Medical Graduate and designed a competency-based module on attitudes and communication. Widespread adoption of a competency-based approach would mean a paradigm shift in the current approach to medical education. CBME, hence, needs to be reviewed for its usefulness and limitations in the Indian context. This article describes the rationale of CBME and provides an overview of its components, i.e., competency, entrustable professional activity, and milestones. It elaborates how CBME could be implemented in an institute, in the context of basic sciences in general and pharmacology in particular. The promises and perils of CBME that need to be kept in mind to maximize its gains are described.
Comprehensive analysis of endogenous bornavirus-like elements in eukaryote genomes

Bornaviruses are the only animal RNA viruses that establish a persistent infection in their host cell nucleus. Studies of bornaviruses have provided unique information about viral replication strategies and virus–host interactions. Although bornaviruses do not integrate into the host genome during their replication cycle, we and others have recently reported that there are DNA sequences derived from the mRNAs of ancient bornaviruses in the genomes of vertebrates, including humans, and these have been designated endogenous borna-like (EBL) elements. Therefore, bornaviruses have been interacting with their hosts as driving forces in the evolution of host genomes in a previously unexpected way. Studies of EBL elements have provided new models for virology, evolutionary biology and general cell biology. In this review, we summarize the data on EBL elements including what we have newly identified in eukaryotes genomes, and discuss the biological significance of EBL elements, with a focus on EBL nucleoprotein elements in mammalian genomes. Surprisingly, EBL elements were detected in the genomes of invertebrates, suggesting that the host range of bornaviruses may be much wider than previously thought. We also review our new data on non-retroviral integration of Borna disease virus.
Polarity, integrin, and extracellular matrix dynamics in the postischemic rat kidney.

Acute renal failure (ARF) as a consequence of ischemic injury is a common disease affecting 5% of the hospitalized population. Despite the fact that mortality from ARF is high, there has been little improvement in survival rates over the last 40 years. The pathogenesis of ARF may be related to substantial changes in cell-cell and cell-extracellular matrix interactions mediated by β1-integrins. On the basis of in vitro and in vivo studies, reorganization of β1-integrins from basal to apical surfaces of injured tubular epithelia has been suggested to facilitate epithelial detachment, contributing to tubular obstruction and backleak of glomerular filtrate. In this study, we examine integrin and extracellular matrix dynamics during epithelial injury and repair using an in vivo rat model of unilateral ischemia. We find that, soon after reperfusion, β1-integrins newly appear on lateral borders in epithelial cells of the S3 segment but are not on the apical surface. At later times, as further injury and regeneration coordinately occur, epithelia adherent to the basement membrane localize β1 predominantly to basal surfaces even while the polarity of other marker proteins is lost. At the same time, amorphous material consisting of depolarized exfoliated cells fills the luminal space. Notably, β1-integrins are not detected on exfoliated cells. A novel finding is the presence of fibronectin, a glycoprotein of plasma and the renal interstitium, in tubular spaces of the distal nephron and to a lesser extent S3 segments. These results indicate that β1-integrins dramatically change their distribution during ischemic injury and epithelial repair, possibly contributing to cell exfoliation initially and to epithelial regeneration at later stages. Together with the appearance of large amounts of fibronectin in tubular lumens, these alterations may play a significant role in the pathophysiology of ARF.
Anticorrelated CN and CH variations on the 47 Tucanae main-sequence turnoff

Observations of CN and CH band strengths among a random sample of main-sequence turn-off stars (+3.9 < MV < +4.6) in the globular cluster 47 Tuc (NGC 104, C0021-723) were made with the CTIO Argus fiber spectrograph for the purpose of determining the ratio of CN-strong to CN-weak stars and investigating the behavior of CH relative to CN. Of the 20 turn-off stars, 12 were found to be CN-strong while 8 appear to be CN-weak. This ratio of CN-strong to CN-weak stars is similar to the ratios found among the more luminous 47 Tuc stars and implies little change in the overall distribution of CN with evolutionary state, although the present sample size is small. A general anticorrelation between CN and CH is also observed in that the CN-weak main-sequence stars all (with one possible exception) exhibit strong CH bands - a trend similar to that found among the brighter stars. That these variations occur among such relatively un-evolved stars and that the overall CN distribution appears to be independent of evolutionary state presents serious challenges to internal or mixing theories of their origin. We therefore suggest that at least some component of the C and N abundance inhomogeneities observed among the brighter (more evolved) stars of this cluster appears to have been established prior to the commencement of evolution up the red giant branch.
The origin and properties of intracluster stars in a rich cluster

We use a multimillion particle N-body + smooth particle hydrodynamics (SPH) simulation to follow the formation of a rich galaxy cluster in a � -cold dark matter (� CDM) cosmology, with the goal of understanding the origin and properties of intracluster stars. The simulation includes gas cooling, star formation, the effects of a uniform ultraviolet background and feedback from supernovae. Haloes that host galaxies as faint as MR =− 19.0 are resolved by this simulation, which includes 85 per cent of the total galaxy luminosity in a rich cluster. We find that the accumulation of intracluster light (ICL) is an ongoing process, linked to infall and stripping events. The unbound star fraction varies with time between 10 and 22 per cent of the total amount of cluster stars, with an overall trend to increase with time. The fraction is 20 per cent at z = 0, consistent with observations of galaxy clusters. The surface brightness profile of the cD galaxy shows an excess compared with a de Vaucouleur profile near 200 kpc, which is also consistent with observations. Both massive and small galaxies contribute to the formation of the ICL, with stars stripped preferentially from the outer, lower-metallicity parts of their stellar distributions. Simulated observations of planetary nebulae (PNe) show significant substructure in velocity space, tracing separate streams of stripped intracluster stars. Despite an unrelaxed distribution, individual intracluster PNe might be useful mass tracers if more than five fields at a range of radii have measured line-of-sight velocities, where an accurate mass calculation depends more on the number of fields than the number of PNe measured per field. However, the orbits of intracluster stars are more anisotropic than those of galaxies or dark matter, which leads to a systematic underestimate of cluster mass relative to that calculated with galaxies, if not accounted for in dynamical models. Overall, the properties of ICL formed in a hierarchical scenario are in good agreement with current observations, supporting a model where ICL originates from the dynamical evolution of galaxies in dense environments. ICL should thus be ubiquitous in galaxy clusters.
A Model for Format Endangerment Analysis using Fuzzy Logic

This paper presents an approach for merging information automatically aggregated from open repositories and expert knowledge related to digital preservation. The main contribution of this work is the employment of fuzzy models to support digital preservation experts with semi-automatic estimation of \endangerment level" for le formats. Our goal is to make use of a solid knowledge base automatically aggregated from linked open data repositories to detect conicts and inaccuracies in this data in order to improve the quality of a risk analysis process. The proposed method is meant to facilitate decision making with regard to preservation of digital content in libraries and archives using knowledge of domain experts. To allow reasoning even in case of inconsistent data we employ fuzzy logic techniques for transforming information about formats in user friendly metrics. The goal is to bring conicting and incorrect information to the surface for correction and improvement by community. The analysis of a survey regarding the risk factors for le formats was used as an input for fuzzy model and is presented in evaluation part.
Allelic loss at the 8p22 region as a prognostic factor in large and estrogen receptor negative breast carcinomas

Allelic losses of tumor suppressor genes, or the chromosomal regions harboring them, in the DNA of tumor cells may become useful postoperative prognostic indicators. The authors studied frequent loss of heterozygosity (LOH) on chromosome 8p22 and its association with disease progression that occurred later in patients with breast carcinoma.
