Finding Idle Periods on Networks of WorkstationsNYU

We present a simple technique for predicting the probability that an idle workstation will continue to be idle for i minutes, given that it has been idle for x minutes (i.e., nd the remaining idle period probability P (i; x)). By idle we mean that the workstation owner is not interactively using the workstation or executing other tasks on it. The results are particularly applicable to the scheduling of tasks in systems that harvest cycles from idle-only workstations. Our Remaining Idle Period Probability Predictor (RIPPP) uses the distribution of the lengths of idle periods on the managed workstations. Collecting, storing, and processing these distributions (in the form of histograms) is a small overhead on modern workstations (a few kilobytes of storage per workstation). We investigated the behavior of our RIPPP with usage traces of 31 workstations collected over a ve month period, and discovered the following six results. (1) The distribution of one month of idle periods predicts the remaining idle period probability in the next month for most workstations. (2) Diierent workstations tend to have signiicantly diierent idle period length distributions. (3) The average length of an idle period does not necessarily correlate well with the probability of being able to nd long idle periods, contrary to intuition and previous scheduling heuristics. (4) A workstation that has been idle a long time does not necessarily have a high probability of remaining idle for a long time. (5) Using the time of day can improve predictions. (6) The length of the previous and the current idle periods are positively correlated, but the length of the previous idle period is not strongly correlated with nding long remaining idle periods. Based on these studies, we conclude that an eeective way to nd idle workstations is to collect their idle period length distribution and use it to compute P (i; x). We believe our analysis will be applicable to predicting the length of busy periods, which is useful for deciding whether to migrate or suspend tasks when a workstation becomes busy (the owner reclaims it). From our results, we have developed a remaining idle period probability toolkit which includes a statistics collector and a prediction library in C. This will be available from our project homepage.
The "Politicization" of Turkish Television Dramas

Turkish television has undergone a distinctive transformation since the early 2000s in which new regulations, rapid market growth, and political pressures have interacted with and transformed each other. As Turkey set new records in 2013 for the highest number of journalists arrested worldwide, television dramas have suffered from their fair share of political pressures, while the contemporary political agenda has, in turn, infiltrated the content of television dramas. This article analyzes the ways in which Turkish television dramas appear as a sphere of political contest.
Rehospitalization because of respiratory syncytial virus infection in premature infants younger than 33 weeks of gestation: a prospective study

Objective. To collect data on hospitalization for respiratory syncytial virus (RSV) infections and presumptive risk factors for rehospitalization among premature infants in Spain. Design. Observational, prospective, longitudinal, multicenter study. Setting. Fourteen Spanish neonatal units with an annual birth cohort of 57 000 infants. Patients. All children (n = 680) born ≤32 weeks of gestational age between April 1, 1998, and March 31, 1999, and discharged from the hospital before March 31, 1999, were included in the study. A total of 96 were excluded because of administration of prophylactic treatment (n = 55) or were lost to follow‐up (n = 41). Five children died during the study period, but death was related to RSV in only 1 case. Methods and main outcome measures. Neonatal and demographic data were recorded at the initial visit. Infants were prospectively followed at monthly intervals up to March 31, 1999. In patients rehospitalized for respiratory disorders, further data about RSV status and morbidity were collected. A comparison was made between children rehospitalized for RSV infection and those who were not. The influence of factors on the probability of rehospitalization for RSV infection was assessed by logistic regression analysis. Results. Of the 584 evaluable patients 118 (20.2%) were rehospitalized for respiratory disease during the study period. The causative pathogen was identified in 89 (75.4%) hospital admissions. Of these 59 (66.3%) were a result of RSV infection in 53 children; 6 were reinfections. In a logistic regression model significant independent prognostic variables included: lower risk of RSV hospitalization with increase gestational age [odds ratio (OR), 0.85; 95% confidence interval (CI), 0.72 to 0.99;P < 0.047]; higher risk with chronic lung disease (OR = 3.1; 95% CI 1.22 to 7.91;P < 0.016); and living with school age siblings (OR = 1.86; 95% CI 1.01 to 3.4;P < 0.048). Conclusion. This large descriptive study has enabled us to define the influence of specific risk factors that increase the risk of rehospitalization for RSV infection in preterm infants. Such studies help to define the appropriate role of available prophylactic interventions and establish treatment guidelines.
Platelets can be a biological compartment for the Hepatitis C Virus

Although HCV has hepatic tropism, the presence of the virus in extra-hepatic compartments has been well documented. Platelets have been described as carriers of the virus in the circulation and may be a natural reservoir for the virus. However, few studies have been performed to evaluate the levels of HCV RNA in plasma and platelets are equal or differ in some way. Therefore, the aim of this study was to perform a comparative evaluation of the stability of HCV RNA in plasma and isolated platelets. Four aliquots of whole plasma obtained from patients infected with HCV were incubated at 37 °C for 0, 48, 96 and 144 h. After incubation, the plasma and platelet pellet was obtained from each aliquot. Viral RNA in plasma and platelets was quantified by q-PCR. The results showed a decrease in HCV RNA levels in plasma with incubation time. However, platelet HCV RNA levels were stable up to 144 h incubation. The results of this study showed that HCV RNA in platelets, although at lower concentrations than in plasma, is preserved from degradation over time, suggesting that the virus may persist longer in the body when associated with platelets, which could have an impact on the efficiency of antiviral therapy.
On the Time Course of Synchronization Patterns of Neuronal Discharges in the Human Brain during Cognitive Tasks

Using intracerebral EEG recordings in a large cohort of human subjects, we investigate the time course of neural cross-talk during a simple cognitive task. Our results show that human brain dynamics undergo a characteristic sequence of synchronization patterns across different frequency bands following a visual oddball stimulus. In particular, an initial global reorganization in the delta and theta bands (2–8 Hz) is followed by gamma (20–95 Hz) and then beta band (12–20 Hz) synchrony.
Continuity and Change in Contemporary Ulster Protestantism*

This paper explores current trends in religious practice, observance and belief in Ulster Protestantism for elements of continuity and change. Using historical and survey data it is clear that there are strong elements of both. However, Protestant religiosity is not changing to the point that it constitutes secularisation, as sociologists of religion understand it. Nor are new trends in religiosity weakening ethno-national identities in Northern Ireland. This is because political identities are socially reproduced in ways that are independent of their religious roots and are thus unaffected by patterns of religiosity. Likely changes in Protestant religiosity in the future therefore offer no immediate panacea for altering the dynamics of Northern Irish politics.
The impact of the Circle of Security-Parenting(c) program on mothers in residential substance abuse treatment: An action research study

Child maltreatment (CM) is a pervasive social problem in the United States that occurs across all socioeconomic, religious, cultural, and ethnic groups (United States Department of Health & Human Services, 2012). Though the causes of CM are complex and involve multiple factors, researchers have found that specific parenting factors are associated with child maltreatment, including harsh discipline practices, hostile attributions, difficulties with emotion regulation, maternal substance abuse, and a parent's personal history of child abuse (Azar, 2002; Belsky & Jaffee, 2006; Mayes & Truman, 2002). Improving parenting through parenting programs is one of the most important approaches to reducing CM (Barth, 2009). The primary purpose of this study was to determine the impact of a manualized, group-based, parenting program on mothers in residential treatment for substance abuse. The Circle of Security-Parenting© (COS-P; Cooper, Hoffman, & Powell, 2009) program is a shortened, eight session version of the original Circle of Security® protocol that has shown efficacy in working with parents at risk for CM (Cassidy et al., 2010; Hoffman, Marvin, Cooper, & Powell, 2006). A secondary purpose involved assessing if COS-P can positively impact three measurable social information processing and attachment variables associated with child maltreatment: (a) hostile attributions (b) emotion regulation, and (c) harsh discipline practices. Utilizing action research methodology, qualitative, quantitative, and secondary data sets were gathered. Quantitative results indicated that some participants who attended the majority of COS-P sessions showed reliable change (Jacobson & Truax, 1991) from pretest to posttest, with the largest changes in parental discipline practices. Qualitatively, COS-P participants, staff members at the agency, and the group researcher/facilitator overwhelmingly commented positively on the new curriculum, with the only noted weakness being more time needed with the curriculum. Further, a review of the participant's background demographic data indicated that participants who had reliable change (i.e., change that was larger than measurement error) on their dependent pretest to posttest measures differed from those who did not have reliable change on their measures on three background variables: education level, self-reported personal history of CM, and time in residential treatment. Results indicate that COS-P is a well-received, engaging program that may impact the parenting factors associated with CM for mothers in residential substance abuse treatment.
The prosodic marking of information status in Malaysian English

This paper investigates the prosodic strategies used by Malaysian speakers of English to mark the information status of new and given discourse elements. Thirty speakers of Malaysian English were recorded both when playing a game designed by Swerts, Krahmer, and Avesani (2002) to elicit semi-spontaneous speech and when reading out a 179-word story. Pitch accent placement in the semi- spontaneous speech was analysed auditorily, while six given and new word pairs in each reading passage were analysed acoustically in terms of the phonetic realisation of the pitch accent (following Atterer and Ladd 2004). In addition, 11 speakers of Malaysian English participated in a perception experiment testing their identification of new and given discourse elements in these recordings. Results show that Malaysian speakers of English do not mark given and new information with distinct pitch accent placement and that it is not possible to categorise these utterance elements unambiguously according to their information status. The acoustic analysis showed that given information is marked by a later pitch trough and a smaller rise than new information. No difference between the two, however, was found in terms of pitch peak alignment.

New potential inhibitors of mTOR: a computational investigation integrating molecular docking, virtual screening and molecular dynamics simulation

The mTOR (mammalian or mechanistic Target Of Rapamycin), a complex metabolic pathway that involves multiple steps and regulators, is a major human metabolic pathway responsible for cell growth control in response to multiple factors and that is dysregulated in various types of cancer. The classical inhibition of the mTOR pathway is performed by rapamycin and its analogs (rapalogs). Considering that rapamycin binds to an allosteric site and performs a crucial role in the inhibition of the mTOR complex without causing the deleterious side effects common to ATP-competitive inhibitors, we employ ligand-based drug design strategies, such as virtual screening methodology, computational determination of ADME/Tox properties of selected molecules, and molecular dynamics in order to select molecules with the potential to become non-ATP-competitive inhibitors of the mTOR enzymatic complex. Our findings suggest five novel potential mTOR inhibitors, with similar or better properties than the classic inhibitor complex, rapamycin.
Mobile infostation network technology

Inefficient use of network resources on the battlefield is a serious liability: if an asset communicates with the network command for data-a terrain map, for instance-it ties up the end-to-end network resources. When many such assets contend for data simultaneously, traffic is limited by the slowest link along the path from the network command to the asset. A better approach is for a local server, known as an infostation, to download data on an anticipated-need basis when the network load is low. The infostation can then dump data when needed to the assets over a high-speed wireless connection. The infostation serves the local assets over an OFDM-based wireless data link that has MIMO enhancements for high data rate and robustness. We aim for data rate in excess of 100 Mbps, spectral efficiency in excess of 5 bits/sec/Hz, and robustness to poor channel conditions and jammers. We propose an adaptive physical layer that determines power levels, modulation schemes, and the MIMO enhancements to use based on the channel state and the level of interference in the system. We also incorporate the idea of superuser: a user who is allowed preferential use of the high data rate link. We propose a MAC that allows for this priority-based bandwidth allocation scheme. The proposed infostation MAC is integrated tightly with the physical layer through a cross-layer design. We call the proposed infostation PHY, MAC, and network technology, collectively, as the Mobile Infostation Network Technology (MINT).
Perceived value in community supported agriculture (CSA)

Purpose – The purpose of this paper is threefold: to conceptualize a construct of the perceived value in CSA and its dimensions, to operationalize and validate the construct, and to empirically investigate the influence of perceived value in CSA on consumer satisfaction and loyalty. Design/methodology/approach – This research begins by reviewing relevant literature that frames the concept of perceived value in CSA and integrates this construct into a nomological network. Operational measures for each component of perceived value in CSA are then developed. The scale is validated, and then used to test the hypothesized model in a sample of 198 consumers of Beijing's five CSA farms using partial least squares (PLS) as an analytical tool. Findings – Perceived value in CSA is found to be a formative, multi-dimensional, third-order construct. Further, the results suggest that perceived value in CSA has both a direct positive effect on consumer loyalty and an indirect effect mediated through consumer satisfactio.
MINETRAC: Mining flows for unsupervised analysis & semi-supervised classification

Driven by the well-known limitations of port-based and payload-based analysis techniques, the use of Machine Learning for Internet traffic analysis and classification has become a fertile research area during the past half-decade. In this paper we introduce MINETRAC, a combination of unsupervised and semi-supervised machine learning techniques capable of identifying and classifying different classes of IP flows sharing similar characteristics. The unsupervised analysis is accomplished by means of robust clustering techniques, using Sub-Space Clustering, Evidence Accumulation, and Hierarchical Clustering algorithms to explore inter-flows structure. MINETRAC permits to identify natural groupings of traffic flows, combining the evidence of data structure provided by different partitions of the same set of traffic flows. Automatic classification is performed by means of semi-supervised learning, using only a small fraction of ground-truth flows to map the identified clusters into their associated most-probable originating network service or application. We evaluate the performance of MINETRAC using real traffic traces, additionally comparing its performance against previously proposed clustering-based flow analysis methods and supervised/semi-supervised classification approaches.
Variational Latent Gaussian Process for Recovering Single-Trial Dynamics from Population Spike Trains

Abstract When governed by underlying low-dimensional dynamics, the interdependence of simultaneously recorded populations of neurons can be explained by a small number of shared factors, or a low-dimensional trajectory. Recovering these latent trajectories, particularly from single-trial population recordings, may help us understand the dynamics that drive neural computation. However, due to the biophysical constraints and noise in the spike trains, inferring trajectories from data is a challenging statistical problem in general. Here, we propose a practical and efficient inference method, the variational latent gaussian process (vLGP). The vLGP combines a generative model with a history-dependent point process observation, together with a smoothness prior on the latent trajectories. The vLGP improves on earlier methods for recovering latent trajectories, which assume either observation models inappropriate for point processes or linear dynamics. We compare and validate vLGP on both simulated data sets and population recordings from the primary visual cortex. In the V1 data set, we find that vLGP achieves substantially higher performance than previous methods for predicting omitted spike trains, as well as capturing both the toroidal topology of visual stimuli space and the noise correlation. These results show that vLGP is a robust method with the potential to reveal hidden neural dynamics from large-scale neural recordings.
A Cross-Sectional Analysis of the Development of Response Inhibition in Children with Chromosome 22q11.2 Deletion Syndrome

Chromosome 22q11.2 deletion syndrome (22q11.2DS) is a neurogenetic disorder that is associated with cognitive impairments and significantly elevated risk for developing schizophrenia. While impairments in response inhibition are central to executive dysfunction in schizophrenia, the nature and development of such impairments in children with 22q11.2DS, a group at high risk for the disorder, are not clear. Here we used a classic Go/No-Go paradigm to quantify proactive (anticipatory stopping) and reactive (actual stopping) response inhibition in 47 children with 22q11.2DS and 36 typically developing (TD) children, all ages 7–14. A cross-sectional design was used to examine age-related associations with response inhibition. When compared with TD individuals, children with 22q11.2DS demonstrated typical proactive response inhibition at all ages. By contrast, reactive response inhibition was impaired in children with 22q11.2DS relative to TD children. While older age predicted better reactive response inhibition in TD children, there was no age-related association with reactive response inhibition in children with 22q11.2DS. Closer examination of individual performance data revealed a wide range of performance abilities in older children with 22q11.2DS; some typical and others highly impaired. The results of this cross-sectional analysis suggest an impaired developmental trajectory of reactive response inhibition in some children with 22q11.2DS that might be related to atypical development of neuroanatomical systems underlying this cognitive process. As part of a larger study, this investigation might help identify risk factors for conversion to schizophrenia and lead to early diagnosis and preventive intervention.
