Who will retweet me?: finding retweeters in twitter

An important aspect of communication in Twitter (and other Social Network is message propagation -- people creating posts for others to share. Although there has been work on modelling how tweets in Twitter are propagated (retweeted), an untackled problem has been who will retweet a message. Here we consider the task of finding who will retweet a message posted on Twitter. Within a learning to-rank framework, we explore a wide range of features, such as retweet history, followers status, followers active time and followers interests. We find that followers who retweeted or mentioned the author's tweets frequently before and have common interests are more likely to be retweeters.
Frontal White Matter Anisotropy and Antidepressant Remission in Late-Life Depression

Introduction Neuroanatomic features associated with antidepressant treatment outcomes in older depressed individuals are not well established. This study used diffusion tensor imaging to examine frontal white matter structure in depressed subjects undergoing a 12-week trial of sertraline. We hypothesized that remission would be associated with higher frontal anisotropy measures, and failure to remit with lower anisotropy. Methods 74 subjects with Major Depressive Disorder and age 60 years or older were enrolled in a twelve-week open-label trial of sertraline and completed clinical assessments and 1.5T magnetic resonance brain imaging. The apparent diffusion coefficient (ADC) and fractional anisotropy (FA) were measured in regions of interest placed in the white matter of the dorsolateral prefrontal cortex, anterior cingulate cortex, and corpus callosum. Differences in ADC and FA values between subjects who did and did not remit to treatment over the study period were assessed using generalized estimating equations, controlling for age, sex, medical comorbidity and baseline depression severity. Results Subjects who did not remit to sertraline exhibited higher FA values in the superior frontal gyri and anterior cingulate cortices bilaterally. There were no statistically significant associations between ADC measures and remission. Conclusions Failure to remit to sertraline is associated with higher frontal FA values. Functional imaging studies demonstrate that depression is characterized by functional disconnection between frontal and limbic regions. Those individuals where this disconnection is related to structural changes as detected by DTI may be more likely to respond to antidepressants. Trial Registration ClinicalTrials.gov NCT00339066
Coxeter Groups act on CAT(0) cube complexes

We show that any finitely generated Coxeter group acts properly discontinuously on a locally finite, finite dimensional CAT(0) cube complex. For any word hyperbolic or right angled Coxeter group we prove that the cubing is cocompact. We show how the local structure of the cubing is related to the partial order studied by Brink and Howlett in their proof of automaticity for Coxeter groups.
Improving coordination in software development through social and technical network analysis

Today’s dynamic and distributed development environment brings significant challenges for software project management. In distributed project settings, “management by walking around” is no longer an option, and project managers may miss out on key project insights. At the same time, the high coordination requirements caused by the dynamic distributed environment can cause many coordination difficulties and can even lead to coordination breakdowns. In response to some of these problems, researchers have developed detailed patterns for describing the preferred relationships between the team communication structure (the social network) and the technical software architecture. We call such patterns Socio-Technical Patterns. As they capture a wide variety of knowledge and experience Socio, Technical and Socio-Technical Patterns (or Socio/Technical Patterns in short) are potentially very useful for the project manager in planning and monitoring complex development projects. However, these patterns are hard to implement and monitor in practice. The reason behind this is that it is difficult to find coordination problems in order to apply the solutions provided by the Socio/Technical Patterns, as purely manual techniques are labour intensive. Especially within dynamic and iterative distributed environments, the use of Socio/Technical Patterns is challenging. But, even in small companies, employing between 20 and 50 developers (ref Chapter 5 and 6), the social network and the relation to the software tasks can get quite complicated for the software manager to track. As part of the TESNA (TEchnical Social Network Analysis) project, we have developed a method and a tool that a project manager can use in order to identify specific coordination problems that we call Socio/Technical Structure Clashes (STSCs). We have evaluated the TESNA method and tool in two commercial case studies (Chapters 5 and 6) and multiple case studies in the Open Source development environment (Chapter 7).
Effect of continuous care model on lifestyle of patients with myocardial infarction

BACKGROUND Myocardial infarction (MI) is a life threatening disease that influences the physical, psychological and social dimensions of the individual. Improper lifestyle is one of the causes of this disease. The use of nursing models could be one of the important and fundamental steps in changing the risk factors associated with MI. This study was carried out to evaluate the effect of continuous care model on the lifestyle of patients with MI. METHODS This randomized clinical trial was carried out on 70 patients with MI in coronary care units of hospitals affiliated to Shiraz University of Medical Sciences. Enrolled patients were randomly assigned to intervention or control groups using a randomization list (random permutated blocks with length 4). The continuous care model was used for 35 patients in the intervention group for a period of 3 months and in the control group, the usual cares were applied for 35 patients. Data were collected through lifestyle questionnaire before the intervention and 3 months after. The data were analyzed using chi-square, independent t-test and paired t-test. RESULTS Patients in the intervention group showed significant improvements in lifestyle (125.6 ± 15.4 vs. 180.1 ± 19.9). Moreover, the lifestyle score of intervention group was significantly better than that of the control group (117.9 ± 22.0 vs. 180.1 ± 19.9; P < 0.001) after three months. CONCLUSION Applying a continuous care model had positive effects on the lifestyle of patients with Myocardial Infarction. In order to reduce the risk factors and improve the lifestyle of patients with MI, nurses could use this model to create an effective change.

Green’s conjecture for curves on arbitrary K3 surfaces

Abstract Green’s conjecture predicts than one can read off special linear series on an algebraic curve, by looking at the syzygies of its canonical embedding. We extend Voisin’s results on syzygies of K3 sections, to the case of K3 surfaces with arbitrary Picard lattice. This, coupled with results of Voisin and Hirschowitz–Ramanan, provides a complete solution to Green’s conjecture for smooth curves on arbitrary K3 surfaces.
Sports Activities in Obese Teenagers Improve Social Inclusion and Health

Obesity is known to be a major risk of whole range of cardio vascular, metabolic and respiratory disorders. The etiology of obesity can be genetic, hormonal and determine the central obesity (or visceral or android). It is characterized by the deposit of fat especially abdominal and recognizable by a waist-hip ratio of more than 0.85 in women and 0.95 in ‘man, and the peripheral (or subcutaneous or gynoid) that shows a ratio of less than 0.85 in women and 0.95 in men. The research was carried out in order to monitor and improve the correct use of the respiratory function of obese adolescents by developing a sports program aimed at reducing body weight and enhancing motor skills on 60 subjects (30 males and 30 females) aged between 14 and 16 years for a period of eight months. Results showed a reduction in body weight for almost all participants. For 26 subjects, the reduction was around 10%, while for others it was around 8%. Only 8 subjects did not signifi cantly change their weight. The improvement of the motor program, on average, was about 9.5%. The phenomenon of obesity is often one of the factors of discomfort conditions in adolescence that slows down the process of social inclusion and highlights “paramorhism” that has negative eff ect on the respiratory function. Sport is one of the most important activities to combat the problem of weight gain because, through the rules of sports disciplines, it favors the acquisition of correct lifestyles.
Exploiting Vestibular Output during LearningResults in Naturally Curved Reaching Trajectories

Teaching a humanoid robot to reach for a visual target is a complex problem in part because of the high dimensionality of the control space. In this paper, we demonstrate a biologically plausible simplification of the reaching process that replaces the degrees of freedom in the neck of the robot with sensory readings from a vestibular system. We show that this simplification introduces errors that are easily overcome by a standard learning algorithm. Furthermore, the errors that are necessarily introduced by this simplification result in reaching trajectories that are curved in the same way as human reaching trajectories.
Expectation-Driven Changes in Cortical Functional Connectivity Influence Working Memory and Long-Term Memory Performance

Expectations generated by predictive cues increase the efficiency of perceptual processing for complex stimuli (e.g., faces, scenes); however, the impact this has on working memory (WM) and long-term memory (LTM) has not yet been investigated. Here, healthy young adults performed delayed-recognition tasks that differed only in stimulus category expectations, while behavioral and functional magnetic resonance imaging data were collected. Univariate and functional-connectivity analyses were used to examine expectation-driven, prestimulus neural modulation, networks that regulate this modulation, and subsequent memory performance. Results revealed that predictive category cueing was associated with both enhanced WM and LTM for faces, as well as baseline activity shifts in a face-selective region of the visual association cortex [i.e., fusiform face area (FFA)]. In addition, the degree of functional connectivity between FFA and right inferior frontal junction (IFJ), middle frontal gyrus (MFG), inferior frontal gyrus, and intraparietal sulcus correlated with the magnitude of prestimulus activity modulation in the FFA. In an opposing manner, prestimulus connectivity between FFA and posterior cingulate cortex, a region of the default network, negatively correlated with FFA activity modulation. Moreover, whereas FFA connectivity with IFJ and the precuneus predicted enhanced expectation-related WM performance, FFA connectivity with MFG predicted LTM improvements. These findings suggest a model of expectancy-mediated neural biasing, in which a single node (e.g., FFA) can be dynamically linked or disconnected from different brain regions depending on prestimulus expectations, and the strength of distinct connections is associated with WM or LTM benefits.

A low-cost approach towards mixed task and data parallel scheduling

A relatively new trend in parallel programming scheduling is the so-called mixed task and data scheduling. It has been shown that mixing task and data parallelism to solve large computational applications often yields better speedups compared to either applying more task parallelism or pure data parallelism. In this paper we present a new compile-time heuristic, named critical path and allocation (CPA), for scheduling data-parallel task graphs. Designed to have a very low cost, its complexity is much lower compared to existing approaches, such as TSAS, TwoL or CPR, by one order of magnitude or even more. Experimental results based on graphs derived from real problems as well as synthetic graphs, show that the performance loss of CPA relative to the above algorithms does not exceed 50%. These results are also confirmed by performance measurements of two real applications (i.e., complex matrix multiplication and Strassen matrix multiplication) running on a cluster of workstations.
Bone Marrow Mesenchymal Stem Cell and Vein Conduit on Sciatic Nerve Repair in Rats

Background: Peripheral nerve repair with sufficient functional recovery is an important issue in reconstructive surgery. Stem cells have attracted extensive research interest in recent years. Objectives: The purpose of this study was to compare the vein conduit technique, with and without the addition of mesenchymal stem cells in gap-less nerve injury repair in rats. Materials and Methods: In this study, 36 Wistar rats were randomly allocated to three groups: In the first group, nerve repair was performed with simple neurorrhaphy (control group), in the second group, nerve repair was done with vein conduit over site (vein conduit group) and in the third group, bone marrow stem cells were instilled into the vein conduit (stem cell group) after nerve repair with vein conduit over site. Six weeks after the intervention, the sciatic function index, electrophysiological study and histological examination were performed. Results: All animals tolerated the surgical procedures and survived well. The sciatic function index and latency were significantly improved in the vein conduit (P = 0.04 and 0.03, respectively) and stem cell group (P = 0.02 and 0.03, respectively) compared with the control group. No significant difference was observed in sciatic function and latency between the vein conduit and stem-cell groups. Moreover, histological analysis showed no significant difference in regenerative density between these two groups. Conclusions: The results of this study showed that the meticulous microsurgical nerve repair, which was performed using the vein tubulization induced significantly better sciatic nerve regeneration. However, the addition of bone marrow mesenchymal stem cell to vein conduit failed to promote any significant changes in regeneration outcome.
Transnational Tongans:The Profile and Re-integration of Return Migrants

This study contributes to the ‘unwritten chapter’ in migration studies, namely transnational return migration, with specific reference to Tongan migrants who have voluntarily returned to live in Tonga. Return migration of transnational Tongans is not ‘permanent’ as their mobility pre and post-return is characterised by circulation or repeated return rather than staying at ‘home’. In examining the circulation of transnational Tongans, two new forms of return migration are identified -‘return for career advancement’ and ‘ancestral return’. These additions to a new typology of return migration represent better the contemporary mobility system of transnational Tongans and suggest a means for addressing ‘brain drain’ through strengthening the ‘Tongan-ness’ of the diaspora while simultaneously stimulating economic development in the Kingdom. Despite these positive dimensions of return, re-integration is a ‘bumpy’ process, and there needs to be a holistic migration strategy if greater numbers in the Tongan diaspora are to return and make their potential contribution to sustainable development in the Island Kingdom.
Half-strings, projectors and multiple D-branes

A sliver state is a classical solution of the string field theory of the tachyon vacuum that represents a background with a single D25-brane. We show that the sliver wavefunctional factors into functionals of the left and right halves of the string, and hence can be naturally regarded as a rank-one projector in a space of half-string functionals. By developing an algebraic oscillator approach we are able to construct higher rank projectors that describe configurations of multiple D-branes of various dimensionalities and located at arbitrary positions. The results bear remarkable similarities with non-commutative solitons.
Case–Control Study of Blood Lead Levels and Attention Deficit Hyperactivity Disorder in Chinese Children

Background Attention deficit/hyperactivity disorder (ADHD) and lead exposure are high-prevalence conditions among children. Objective Our goal was to investigate the association between ADHD and blood lead levels (BLLs) in Chinese children, adjusting for known ADHD risk factors and potential confounding variables. Methods We conducted a pair-matching case–control study with 630 ADHD cases and 630 non-ADHD controls 4–12 years of age, matched on the same age, sex, and socioeconomic status. The case and control children were systematically evaluated via structured diagnostic interviews, including caregiver interviews, based on the Diagnostic and Statistical Manual of Mental Disorders, 4th ed., revised criteria (DSM-IV-R). We evaluated the association between BLLs and ADHD using the Pearson chi-square test for categorical variables and the Student t-test for continuous data. We then performed conditional multiple variables logistic regression analyses with backward stepwise selection to predict risk factors for ADHD. Results There was a significant difference in BLLs between ADHD cases and controls. ADHD cases were more likely to have been exposed to lead during childhood than the non-ADHD control subjects, with adjustment for other known risk factors [children with BLLs ≥ 10 μg/dL vs. ≤ 5 μg/dL; OR = 6.0; 95% confidence interval (CI) = 4.10–8.77, p < 0.01; 5–10 μg/dL vs.≤ 5 μg/dL, OR = 4.9; 95% CI = 3.47–6.98, p < 0.01]. These results were not modified by age and sex variables. Conclusions This was the largest sample size case–control study to date to study the association between BLLs and ADHD in Chinese children. ADHD may be an additional deleterious outcome of lead exposure during childhood, even when BLLs are < 10 μg/dL.
Service identification and definition frameworks

Companies are interested in implementing Service Oriented Architecture (SOA) but they are missing the methods and the frameworks describing how they should do it. Some frameworks have been suggested. When designing SOA, the analysis and the service identification and definition phases are crucial to reach a good architectural plan. I present and evaluate some of the suggested analysis and design frameworks based on the guidance and means they offer for a starting SOA company. Two of the frameworks are described and evaluated in more detail.
Short-Term Effects of Chlorpromazine on Oxidative Stress in Erythrocyte Functionality: Activation of Metabolism and Membrane Perturbation

The purpose of this paper is to focus on the short-term effects of chlorpromazine on erythrocytes because it is reported that the drug, unstable in plasma but more stable in erythrocytes, interacts with erythrocyte membranes, membrane lipids, and hemoglobin. There is a rich literature about the side and therapeutic effects or complications due to chlorpromazine, but most of these studies explore the influence of long-term treatment. We think that evaluating the short-term effects of the drug may help to clarify the sequence of chlorpromazine molecular targets from which some long-term effects derive. Our results indicate that although the drug is primarily intercalated in the innermost side of the membrane, it does not influence band 3 anionic flux, lipid peroxidation, and protein carbonylation processes. On the other hand, it destabilizes and increases the autooxidation of haemoglobin, induces activation of caspase 3, and, markedly, influences the ATP and reduced glutathione levels, with subsequent exposure of phosphatidylserine at the erythrocyte surface. Overall our observations on the early stage of chlorpromazine influence on erythrocytes may contribute to better understanding of new and interesting characteristics of this compound improving knowledge of erythrocyte metabolism.
Comparative Cellular Toxicity of Hydrophilic and Hydrophobic Microcystins on Caco-2 Cells

Microcystins (MC), cyanobacterial peptide hepatotoxins, comprise more than 100 different variants. They are rather polar molecules but some variants contain hydrophobic amino acid residues in the highly variable parts of the molecule. In MC-LF and MC-LW, the more hydrophobic phenylalanine (F) and tryptophan (W), respectively, have replaced arginine (R) in MC-LR. Depending on the structure, microcystins are expected to have different in vivo toxicity and bioavailability, but only a few studies have considered the toxic properties of the more hydrophobic variants. The present study shows that MC-LF and MC-LW have more pronounced cytotoxic effects on Caco-2 cells as compared to those of MC-LR. Treatment of Caco-2 cells with MC-LW and especially MC-LF showed clear apoptotic features including shrinkage and blebbing, and the cell–cell adhesion was lost. An obvious reduction of cell proliferation and viability, assessed as the activity of mitochondrial dehydrogenases, was observed with MC-LF, followed by MC-LW and MC-LR. Cytotoxicity was quantified by measuring lactate dehydrogenase leakage. The more hydrophobic MC-LW and MC-LF induced markedly enhanced lactate dehydrogenase leakage compared to controls and MC-LR, indicating that the plasma membrane was damaged. All of the three toxins examined inhibited protein phosphatase 1, with MC-LF and MC-LW to a weaker extent compared to MC-LR. The higher toxic potential of the more hydrophobic microcystins could not be explained by the biophysical experiments performed. Taken together, our data show that the more hydrophobic microcystin variants induce higher toxicity in Caco-2 cells.
