Content placement for video streaming over cellular networks

The issue of content placement for video streaming over cellular networks is addressed in this study. Our method was verified using real video streaming data taken from traces of live content distribution networks. Simulation results show that replicating a relatively small number of video files can significantly reduce the incoming bandwidth from the Internet backbone, as well as the (time) latency for content delivery.
Silencing of the CaCP Gene Delays Salt- and Osmotic-Induced Leaf Senescence in Capsicum annuum L.

Cysteine proteinases have been known to participate in developmental processes and in response to stress in plants. Our present research reported that a novel CP gene, CaCP, was involved in leaf senescence in pepper (Capsicum annuum L.). The full-length CaCP cDNA is comprised of 1316 bp, contains 1044 nucleotides in open reading frame (ORF), and encodes a 347 amino acid protein. The deduced protein belongs to the papain-like cysteine proteases (CPs) superfamily, containing a highly conserved ERFNIN motif, a GCNGG motif and a conserved catalytic triad. This protein localized to the vacuole of plant cells. Real-time quantitative PCR analysis revealed that the expression level of CaCP gene was dramatically higher in leaves and flowers than that in roots, stems and fruits. Moreover, CaCP transcripts were induced upon during leaf senescence. CaCP expression was upregulated by plant hormones, especially salicylic acid. CaCP was also significantly induced by abiotic and biotic stress treatments, including high salinity, mannitol and Phytophthora capsici. Loss of function of CaCP using the virus-induced gene-silencing technique in pepper plants led to enhanced tolerance to salt- and osmotic-induced stress. Taken together, these results suggest that CaCP is a senescence-associated gene, which is involved in developmental senescence and regulates salt- and osmotic-induced leaf senescence in pepper.
Dynamical Low-Rank Approximation

For the low-rank approximation of time-dependent data matrices and of solutions to matrix differential equations, an increment-based computational approach is proposed and analyzed. In this method, the derivative is projected onto the tangent space of the manifold of rank-$r$ matrices at the current approximation. With an appropriate decomposition of rank-$r$ matrices and their tangent matrices, this yields nonlinear differential equations that are well suited for numerical integration. The error analysis compares the result with the pointwise best approximation in the Frobenius norm. It is shown that the approach gives locally quasi-optimal low-rank approximations. Numerical experiments illustrate the theoretical results.
Unsupervised Feature Selection for Multi-View Data in Social Media

The explosive popularity of social media produces mountains of high-dimensional data and the nature of social media also determines that its data is often unlabelled, noisy and partial, presenting new challenges to feature selection. Social media data can be represented by heterogeneous feature spaces in the form of multiple views. In general, multiple views can be complementary and, when used together, can help handle noisy and partial data for any single-view feature selection. These unique challenges and properties motivate us to develop a novel feature selection framework to handle multi-view social media data. In this paper, we investigate how to exploit relations among views to help each other select relevant features, and propose a novel unsupervised feature selection framework, MVFS, for multiview social media data. We systematically evaluate the proposed framework in multi-view datasets from social media websites and the results demonstrate the effectiveness and potential of MVFS.

Mathematisches Forschungsinstitut Oberwolfach Report No . 55 / 2005 Set Theory

This meeting covered all important aspects of modern Set Theory, including large cardinal theory, combinatorial set theory, descriptive set theory, connections with algebra and analysis, forcing axioms and inner model theory. The presence of an unusually large number (19) of young researchers made the meeting especially dynamic. Mathematics Subject Classification (2000): 03Exx. Introduction by the Organisers This meeting was organised by Sy-David Friedman (University of Vienna), Menachem Magidor (Hebrew University, Jerusalem) and Hugh Woodin (University of California, Berkeley). Largely due to the generous EU support for the meeting, we were able to invite an unusually large number of young researchers (at most 10 years after the beginning of doctoral studies). We consequently chose an unusual format for the meeting, in which young people were given priority in the scheduling of lectures. This turned out to be a good choice, as the quality of these lectures was extremely high, giving us an excellent opportunity to learn about the new talent that has recently come into our field. 45-minute lectures were delivered by Krueger (Vienna), Dobrinen (Vienna), Camerlo (Torino), Zoble (Toronto), Geschke (Berlin), König (Paris), Viale (Paris), Asperó (Barcelona), Sharon (Irvine) and Lopez-Abad (Paris). These young people presented striking new results concerning combinatorial set theory, descriptive set theory, set-theoretic analysis and forcing axioms. One of the most impressive of these new results was that of Viale, who established a connection between two important set-theoretic principles, by showing that the singular cardinal hypothesis follows from the proper forcing axiom. 3122 Oberwolfach Report 55/2005 Shorter lectures (20 to 30 minutes) were given by the more senior researchers. In total, lectures were held by 29 of the 59 participants. By restricting the number and length of these lectures, we were able to leave substantial time for private discussion. The 15-minute breaks between lectures were especially appreciated, giving the meeting a relaxed feeling. The traditional Wednesday afternoon walk was a success. The Schwarzwaldkirschtorte in Wolfach was superb, and despite the rain and getting (slightly) lost in the dark, everyone made it safely back to the institute in time for dinner.
Types of stressors and bullying perpetration among female adolescents in Korea

ABSTRACT Research concerning bullying among female adolescents in Korea remains extremely limited. This study examined the impact of three different types of stressors (family stress, friendship stress, and school stress) on bullying perpetration among Korean female adolescents. Five middle schools were randomly selected from 11 schools in Pyeongtaek, Korea. Participants in the study were 374 female students in 7–9th grade. A linear regression analysis based on the different types of stressors was conducted. Findings indicate that family and school related stressors were significantly associated with bullying perpetration. Results supported Bronfenbrenner’s bioecological systems theory. Interventions to decrease family stress and school stress are supported for Korean female adolescents engaged in bullying perpetration.

Window-based feature extraction framework for machine-printed/handwritten and Arabic/Latin text discrimination

In this paper, we propose a new writing type and script text classification technique to recognize the identity of texts extracted from heterogeneous document images. English, French and Arabic languages are used in these documents with mixed handwritten and machine-printed types. In order to identify each text-line/word image, we propose to use 23 features computed on a fixed-length sliding window. Gaussian Mixture Models (GMMs) are used to achieve the classification objective. This framework has been tested on machine-printed and handwritten text-blocks, text-lines and words extracted from different document images of the Maurdor database. Experimental results reveal the effectiveness of our proposed system in writing type and script identification.
SHP-2 Binds to Caveolin-1 and Regulates Src Activity via Competitive Inhibition of CSK in Response to H2O2 in Astrocytes

Reactive oxygen species (ROS) regulate diverse cellular functions by triggering signal transduction events, such as Src and mitogen-activated protein (MAP) kinases. Here, we report the role of caveolin-1 and Src homology 2 domain-containing protein tyrosine phosphatase 2 (SHP-2) in H2O2-induced signaling pathway in brain astrocytes. H2O2-mediated oxidative stress induced phosphorylation of caveolin-1 and association between p-caveolin-1 and SHP-2. SHP-2 specifically bound to wild-type caveolin-1 similarly to c-Src tyrosine kinase (CSK), but not to phosphorylation-deficient mutant of caveolin-1 (Y14A), and interfered with complex formation between caveolin-1 and CSK. In the presence of CSK siRNA, binding between caveolin-1 and SHP-2 was enhanced by H2O2 treatment, which led to reduced Src phosphorylation at tyrosine (Tyr) 530 and enhanced Src phosphorylation at Tyr 419. In contrast, siRNA targeting of SHP-2 facilitated H2O2-mediated interaction between caveolin-1 and CSK and enhanced Src phosphorylation at Tyr 530, leading to subsequent decrease in Src downstream signaling, such as focal adhesion kinase (FAK) and extracellular signal-related kinase (ERK). Our results collectively indicate that SHP-2 alters Src kinase activity by interfering with the complex formation between CSK and phosphotyrosine caveolin-1 in the presence of H2O2, thus functions as a positive regulator in Src signaling under oxidative stress in brain astrocytes.
Postsuburban Spatial Evolution of Vienna's Urban Fringe: Evidence from Point Process Modeling

Metropolitan areas today are faced with pervasive changes of their urban spatial structure and are reshaped by postsuburbanization processes. In this study, one example of such postsuburban restructuring, the multinucleated monofunctional clustering of higher-order services, is investigated in the urban fringe of Vienna, Austria. The methodological framework uses microgeographic data for 2006 and applies a case-control point process modeling approach, which accounts for nonstationarity in first-order effects. The results show a relocation of highly specialized firms into the outer metropolitan ring, where these firms provide functional enrichment. This disagrees with the classical notion of a central place hierarchy. The urban fringe thus increasingly conforms to the core city. This spatial functional agglomeration shows statistically significant evidence of a bicentric urban structure, with the two new subcenters located in traditional suburban areas. Accordingly, Vienna's urban fringe is being altered by new postsuburban forms.
Fever of unknown origin in elderly patients.

INTRODUCTION Causes of fever of unknown origin are different. It is considered that it can be caused with over 200 different clinical entities. Aetiological causes differ according to different categories of age. Febricity in the elderly is at most the result of autoimmune processes, malignancies, bacterial infections and vasculitis. OBJECTIVE The aim of this study was to determine the most common characteristics of fever, the most common laboratory, bacterial and viral tests and to analyze applied therapy in patients with unknown febrile state, and to affirm final diagnosis in elderly patients, as well as younger than 65 years old, and to define outcome of disease in both groups of patients. METHODS Research comprised 100 patients who had been treated at the Infectious Disease Clinic of the Clinical Centre of Vojvodina in Novi Sad, during a three-year period, and in whom fever of unknown origin had been diagnosed. Patients were divided into two homogenous groups of 50 people. The first one (S) consisted of patients older than 65 years, and the second, control group (K) was constituted of patients younger than the age of 65. All of them were chosen by random sample method. RESULTS Average results of standard laboratory parameters of infection were obtained, such as erythrocyte sedimentation rate (ESR), fibrinogen, CRP, and especially leukocyte, and those were significantly higher in the group of elderly patients. The cause had not been found in 10% of elderly patient group, and in the younger group, not even in the third of patients. Among known causative agents dominant were infections, usually of respiratory and urinary tract, in both tested groups. Even 28% of the elderly had sepsis, and 10% endocarditis. Malignant diseases were more frequent in group of the elderly patients, and immune i.e. systematic disorders were evenly noticed in both groups of patients. CONCLUSION Despite advanced studies in medicine, and existence of modern diagnostic procedures, fever of unknown origin is still today differential diagnostic problem.
The Estimation of Mechanical Properties of Polymers from Molecular Structure

The use of semiempirical and empirical relationships have been developed to estimate the mechanical properties of polymeric materials. Based on these relationships, properties can be calculated from only five basic molecular properties. They are the molecular weight, van der Waals volume, the length and number of rotational bonds in the repeat unit, as well as the Tg of the polymer. Since these are fundamental molecular properties, they can be obtained from either purely theoretical calculations or from group contributions. The use of these techniques by polymer chemists can provide a screening technique that will significantly diminish their bench time so that they may pursue more creatively the design of new polymeric materials.
Defective Expression of the Mitochondrial-tRNA Modifying Enzyme GTPBP3 Triggers AMPK-Mediated Adaptive Responses Involving Complex I Assembly Factors, Uncoupling Protein 2, and the Mitochondrial Pyruvate Carrier

GTPBP3 is an evolutionary conserved protein presumably involved in mitochondrial tRNA (mt-tRNA) modification. In humans, GTPBP3 mutations cause hypertrophic cardiomyopathy with lactic acidosis, and have been associated with a defect in mitochondrial translation, yet the pathomechanism remains unclear. Here we use a GTPBP3 stable-silencing model (shGTPBP3 cells) for a further characterization of the phenotype conferred by the GTPBP3 defect. We experimentally show for the first time that GTPBP3 depletion is associated with an mt-tRNA hypomodification status, as mt-tRNAs from shGTPBP3 cells were more sensitive to digestion by angiogenin than tRNAs from control cells. Despite the effect of stable silencing of GTPBP3 on global mitochondrial translation being rather mild, the steady-state levels and activity of Complex I, and cellular ATP levels were 50% of those found in the controls. Notably, the ATPase activity of Complex V increased by about 40% in GTPBP3 depleted cells suggesting that mitochondria consume ATP to maintain the membrane potential. Moreover, shGTPBP3 cells exhibited enhanced antioxidant capacity and a nearly 2-fold increase in the uncoupling protein UCP2 levels. Our data indicate that stable silencing of GTPBP3 triggers an AMPK-dependent retrograde signaling pathway that down-regulates the expression of the NDUFAF3 and NDUFAF4 Complex I assembly factors and the mitochondrial pyruvate carrier (MPC), while up-regulating the expression of UCP2. We also found that genes involved in glycolysis and oxidation of fatty acids are up-regulated. These data are compatible with a model in which high UCP2 levels, together with a reduction in pyruvate transport due to the down-regulation of MPC, promote a shift from pyruvate to fatty acid oxidation, and to an uncoupling of glycolysis and oxidative phosphorylation. These metabolic alterations, and the low ATP levels, may negatively affect heart function.
Learning to Learn with Compound HD Models

We introduce HD (or "Hierarchical-Deep") models, a new compositional learning architecture that integrates deep learning models with structured hierarchical Bayesian models. Specifically we show how we can learn a hierarchical Dirichlet process (HDP) prior over the activities of the top-level features in a Deep Boltzmann Machine (DBM). This compound HDP-DBM model learns to learn novel concepts from very few training examples, by learning low-level generic features, high-level features that capture correlations among low-level features, and a category hierarchy for sharing priors over the high-level features that are typical of different kinds of concepts. We present efficient learning and inference algorithms for the HDP-DBM model and show that it is able to learn new concepts from very few examples on CIFAR-100 object recognition, handwritten character recognition, and human motion capture datasets.
The performance of Tetranychus urticae on five melon cultivars is correlated with leaf thickness

Abstract The two-spotted spider mite, Tetranychus urticae Koch (Acari: Tetranychidae), is an important pest of melons. In this laboratory study, we used two-sex life table to evaluate the performance of T. urticae on five melon cultivars (IVF28, IVF118, IVF168, IVF437, and Yangjiaomi). We also evaluated the correlation between mite population growth and morphological characteristics of leaves. The results showed that the total immature time, adult longevity, total longevity, and fecundity of the spider mite differed among the cultivars. On IVF28, the values for the intrinsic rate of increase (r) and the finite rate of increase (λ) were 0.1638 d-1 and 1.1178 d-1, respectively, which were significantly lower than the values on IVF168, IVF118, or Yangjiaomi. Values for r and λ tended to be highest on IVF168. In addition, r values for T. urticae were not correlated with trichome density or stomatal density but were negatively correlated with melon leaf thickness. In summary, the different melon cultivars exhibited distinct levels of resistance to T. urticae and the IVF28 cultivar was considered the least favored for the growth and reproduction of T. urticae mites, and such differences of mite performance might be related to the leaf thickness, instead of trichome density or stomatal density.
The Range of Attractant Concentrations for Bacterial Chemotaxis and the Threshold and Size of Response over This Range

Attractant was added to a suspension of bacteria (the background concentration of attractant) and then these bacteria were exposed to a yet higher concentration of attractant in a capillary. Chemotaxis was measured by determining how many bacteria accumulated in the capillary. The response range for chemotaxis lies between the threshold concentration and the saturating concentration. The breadth of this range is different for attractants detected by different chemoreceptors. Attractants detected by the same chemoreceptor can have their response ranges in widely different places. Over the center of the response range (on a logarithmic scale), bacteria give similar sized responses to similar fractional increases of concentration, i.e. they respond to ratios of attractant concentration, but the response peaks at the center of the range. The size of the response is different for attractants detected by different chemoreceptors. For a detectable response, a smaller increase in attractant concentration is needed for attractants detected by some chemoreceptors than for attractants detected by others. Although the data are inadequate, it appears that the Weber law may be observed over a wide range of concentrations for some attractants but not for others. In the Appendix we aim to explain some of these results in terms of the interaction of an attractant with its chemoreceptor according to the law of mass action.
