Building Efficient Limited Scale-Free Overlay Topologies for Unstructured P 2 P Networks

In addition to the peer/data organization and search algorithm, the overlay network topology (logical connectivity graph) among peers is a crucial component in unstructured peer-to-peer (P2P) networks. Its topological characteristics significantly affect the efficiency of a search on such unstructured P2P networks. Scale-free (power-law) overlay network topologies are one type of the structures that offer high performance for these networks. However, a key problem for these topologies is the high connectivity (i.e., load) in only a small portion (i.e., hubs) of nodes. In fact, the peers in a typical unstructured P2P network may not want or be able to cope with such high connectivity/load. Therefore, some hard cutoffs are often imposed on the number of edges that each peer can have to achieve implementation feasibility and fairness among all peers, resulting in limited or truncated scale-free networks. In this paper, we discuss and analyze the growth of such limited scale-free networks and propose two different algorithms for constructing perfect scale-free overlay network topologies with flexible scale-free growth exponent (γ) and with low communication overhead during the construction phase. Through extensive simulations, we also evaluate the performance of proposed approaches and compare them with existing solutions. The simulation results demonstrate that the proposed approaches indeed generate perfect scale free networks and can achieve the best performance in different search algorithms with right parameters with much smaller overhead than the existing solutions.
Non-alcoholic duct destructive chronic pancreatitis

Background—The pathology of non-alcoholic chronic pancreatitis has not yet been sufficiently studied. Aims—To identify the major changes of pancreatic tissue in patients surgically treated for non-alcoholic chronic pancreatitis. Patients—Pancreatectomy specimens from 12 patients with non-alcoholic chronic pancreatitis, including four patients with autoimmune or related diseases (Sjögren’s syndrome, primary sclerosing cholangitis, ulcerative colitis, and Crohn’s disease), were reviewed. Methods—Morphological changes were studied histologically and immunohistochemically (to type inflammatory cells) and compared with the pancreatic alterations found in 12 patients with alcoholic chronic pancreatitis. Results—In patients with non-alcoholic chronic pancreatitis, with or without associated autoimmune or related diseases, pancreatic inflammation particularly involved the ducts, commonly resulting in duct obstruction and occasionally duct destruction. None of these features was seen in alcoholic chronic pancreatitis which, however, showed pseudocysts and calcifications. Conclusion—The pancreatic changes in patients with non-alcoholic chronic pancreatitis clearly differ from those with alcoholic chronic pancreatitis. The term chronic duct destructive pancreatitis is suggested for this type of pancreatic disease.
Obsessivecompulsive disorder and traumatic brain injury: behavioral, cognitive, and neuroimaging findings.

OBJECTIVE The goal of this study was to evaluate behavior and cognition in a consecutive series of patients who developed obsessive-compulsive disorder (OCD) after suffering a traumatic brain injury (TBI). BACKGROUND Because OCD is a rare sequelae of TBI, the phenomenology of obsessions and compulsions, the comorbid psychiatric disorders, the performance on cognitive tests, and the neural correlates have not been well characterized. METHODS Ten adult patients who met DSM-IV diagnostic criteria for OCD after suffering either mild (6 cases), moderate (2 cases), or severe (2 cases) TBI were studied using structured psychiatric rating scales (i.e., Yale-Brown Obsessive Compulsive Scale), cognitive tests, and magnetic resonance imaging (MRI). RESULTS Global severity of OCD ranged from moderate to severe, and all patients had multiple obsessions and compulsions. There was a high frequency of aggressive, contamination, need for symmetry/exactness, somatic, and sexual obsessions as well as cleaning/washing, checking, and repeating compulsions. Unusual features such as obsessional slowness (3 cases) and compulsive exercising (3 cases) were also documented. Comorbid psychiatric diagnoses were common and included posttraumatic stress disorder, anxiety with panic attacks, depression, and intermittent explosive disorder. Compared with 10 age-matched normal controls, the OCD group had poor performance on tests of general intelligence, attention, learning, memory, word-retrieval, and executive functions; these cognitive deficits were more pervasive among patients displaying obsessional slowness. All OCD patients with mild TBI had normal MRI scans, whereas focal contusions in the frontotemporal cortices, subcortical structures (caudate nucleus), or both were found in OCD patients with moderate and severe TBI. CONCLUSIONS Posttraumatic OCD has a relatively specific pattern of symptoms even in patients with mild TBI and is associated with a variety of other psychiatric disorders, particularly non-OCD anxiety. The patterns of cognitive deficits and MRI findings suggest dysfunction of frontal-subcortical circuits.
The expression of wild-type pendrin (SLC26A4) in human embryonic kidney (HEK 293 Phoenix) cells leads to the activation of cationic currents.

OBJECTIVE The SLC26A4 protein (pendrin) seems to be involved in the exchange of chloride with other anions, therefore being responsible for iodide organification in the thyroid gland and the conditioning of the endolymphatic fluid in the inner ear. Malfunction of SLC26A4 leads to Pendred syndrome, characterized by mild thyroid dysfunction often associated with goiter and/or prelingual deafness. The precise function of the SLC26A4 protein, however, is still elusive. An open question is still whether the SLC26A4-induced ion exchange mechanism is electrogenic or electroneutral. Recently, it has been shown that human pendrin expressed in monkey cells leads to chloride currents. METHODS We overexpressed the human SLC26A4 isoform in HEK293 Phoenix cells and measured cationic and anionic currents by the patch-clamp technique in whole cell configuration. RESULTS Here we show that human pendrin expressed in human cells does not lead to the activation of chloride currents, but, in contrast, leads to an increase of cationic currents. CONCLUSION Our experiments suggest that the SLC26A4-induced chloride transport is electroneutral when expressed in human cellular systems.
Running Headline: PARENTING STRESS AND AFFECTION Maternal Affection Moderates the Associations between Parenting Stress and Early Adolescents’ Externalizing and Internalizing Behavior

The present study investigated the role of parenting stress in early adolescents’ externalizing and internalizing behavior and, particularly, the moderating effect of maternal affection on these associations. The data of 992 early adolescents (Mage = 12.71; 454 girls) and their mothers during the transition from primary school to lower secondary school were analyzed. The results showed that when maternal affection was low, parenting stress was not related to the changes in early adolescents’ externalizing or internalizing behavior. In contrast, when maternal affection was high, low parenting stress related to a decrease and high parenting stress to an increase in such behaviors. The results were statistically significant and stronger for internalizing behavior; for externalizing behavior they were marginally significant but showed the same pattern. Overall, the results support the idea that maternal affection provides a context which intensifies (rather than ameliorates) the influence of parenting stress on early adolescents’ externalizing and internalizing behavior.
Key selection criteria for third party logistics in the IC manufacturing industry

Globalization and the shift towards outsourcing have strengthened the need for strong relationship between Third Party Logistics (TPL) and the supply chain. The continuing trend of the IC industry disintegration has resulted in specialized companies that are independent yet co-dependent upon one another. To gain the competitive advantage through a seamless integration with TPL, the IC manufacturing industry sets a very high standard of TPL provider selection. The goal of this paper is to identify the key selection criteria of TPL providers from the empirical study of the IC manufacturing industry in Taiwan, one of the largest IC producers worldwide. The research result indicates that Performance, Cost, and Service are the top three criteria dimensions, in which the Document Accuracy, Problem Solving Capability, Continuous Cost Reduction, Cost Control of Value-added Services, and Value-added Services provision are the top five individual selection criteria. The research result can serve as a valuable reference for other companies with similar industrial characteristics as IC manufacturers.
On the Origin and Characteristics of Noise-Induced Lévy Walks of E. Coli

Lévy walks as a random search strategy have recently attracted a lot of attention, and have been described in many animal species. However, very little is known about one of the most important issues, namely how Lévy walks are generated by biological organisms. We study a model of the chemotaxis signaling pathway of E. coli, and demonstrate that stochastic fluctuations and the specific design of the signaling pathway in concert enable the generation of Lévy walks. We show that Lévy walks result from the superposition of an ensemble of exponential distributions, which occurs due to the shifts in the internal enzyme concentrations following the stochastic fluctuations. With our approach we derive the power-law analytically from a model of the chemotaxis signaling pathway, and obtain a power-law exponent , which coincides with experimental results. This work provides a means to confirm Lévy walks as natural phenomenon by providing understanding on the process through which they emerge. Furthermore, our results give novel insights into the design aspects of biological systems that are capable of translating additive noise on the microscopic scale into beneficial macroscopic behavior.

A Two-Phase Plagiarism Detection Method

In this paper we describe a two-phase plagiarism detection method, which we have used in the learning management system of SCUT to detect plagiarism in the network engineering related courses. And we also used this method to detect external plagiarism in the PAN-10 competition. The method is divided into two steps: the first step, called pre-selecting, is to narrow the scope of detection using the successive same fingerprint; the second step, called locating, is to find and merge all fragments between two documents using cluster method. Our method ran 19 hours in the PAN-10 competition, and the result ranked the second place, which met our expectation.
Joint modelling of repeated measurements and time-to-event outcomes: flexible model specification and exact likelihood inference

Random effects or shared parameter models are commonly advocated for the analysis of combined repeated measurement and event history data, including dropout from longitudinal trials. Their use in practical applications has generally been limited by computational cost and complexity, meaning that only simple special cases can be fitted by using readily available software. We propose a new approach that exploits recent distributional results for the extended skew normal family to allow exact likelihood inference for a flexible class of random‐effects models. The method uses a discretization of the timescale for the time‐to‐event outcome, which is often unavoidable in any case when events correspond to dropout. We place no restriction on the times at which repeated measurements are made. An analysis of repeated lung function measurements in a cystic fibrosis cohort is used to illustrate the method.
Beyond the Bosphorus? Comparing German, French, and British Discourses on Turkey's Application to Join the European Union. IHS Political Science Series Paper, No. 111, December 2006

This article examines the impact of national borders on public discourses, based on a case study of the struggle surrounding Turkey’s application to join the European Union (EU). Comparing opinions, reasons and interpretation patterns in press commentaries about enlarging the EU beyond the Bosphorus, the findings confirm the paramount importance and robustness of national cleavages between the German and the French public sphere on the one hand, and the British on the other. Whereas Turkish membership was predominantly re-jected on the continent, the British commentators strongly and almost unanimously sup-ported Ankara’s request to open doors. These similarities and divergences, I argue, are first and foremost the result of, and linked with, competing visions of Europe’s finality, especially regarding various constitutional ideas and cultural principles. Against this background, the Turkey question was partly exploited as an instrument supporting or repressing different conceptions of the European Union’s future.
On the Long-Run Determinants of the U.S. Trade Balance: A Comment

In a recent article in this joumal, Bahmani-Oskooee (1992) used the augmented Dickey-Fuller (ADF) test and a cointegration technique to detennine what variables have long-run relationships with the U.S. current account and trade balance. He finds that "ffie only variable that has a long-run relation with the current account or the trade balance is the full-employment budget" (p. 90). On the basis of this finding, the author concludes that there is strong support for the use of fiscal policy as a tool for coping with U.S. trade problems. Furthennore, he goes on, "our results indicate that a real ornominal effective exchange rate and tenns of trade do not have any long-run relation with the current account or the trade balance"' (p. 92). The purpose of this note is to point out that the statistical finding on which Bahmani-Oskooee bases his conclusion was derived on a particular method of hypothesis testing and econometric analysis. As I will show, these methods are somewhat outdated and inefficient, and had different and more powerful techniques been applied, the finding and conclusion would have been different. In fact, the research supported by these alternative and newer methodologies indicates that, contrary to the conclusions of Bahmani-Oskooee, (a) the current account (CA) and trade balance (TB), respectively, have long-run relationships with the M2 money supply, the tenns of trade (TOT), and the nominal exchange rate (NEX), and (b) TB is not
Effects of Psychosocial Interventions for School-aged Children's Internet Addiction, Self-control and Self-esteem: Meta-Analysis

Objectives This study was conducted to perform an effect size analysis of psychosocial interventions for internet addiction and to identify the intervention moderators applied to school-aged children. Methods For the meta-analysis, studies were included that were published in English or Korean until January 2015, without limitation in terms of the year. They were retrieved from 11 electronic databases and by manual searches according to predefined inclusion criteria. Results A total of 37 studies were selected, which included 11 treatment conditions and covered a total of 1,490 participants. The effect size estimates showed that psychosocial interventions had a large effect for reducing internet addiction (standardized mean difference [SMD], –1.19; 95% confidence interval [CI], –1.52 to –0.87) and improving self-control (SMD, 0.29; 95% CI, 0.11 to 0.47) and self-esteem (mean difference, 3.58; 95% CI, 2.03 to 5.12). The moderator analyses reveals that group treatments, a selective approach, a long duration, a community setting, or higher school grade had a larger effect. Conclusions The findings of this review suggest that psychosocial intervention may be used to prevent Internet addiction in school-aged children, although further research should be conducted using a randomized controlled trial design or diverse age groups to provide evidence-based recommendations.
Entrepreneurial Behaviour of Farmers in Marathwada Region

The investigation was conducted during year 2012-2013 to study the entrepreneurial behaviour of farmers in Marathwada region of Maharashtra by selecting 125 respondents through random sampling. A pretested structured interview schedule was used to collect the information through personal interview method. Data analyzed by using mean, frequency, percentage, standard deviation and correlation co-efficient. Majority of farmers (51.20%) belonged to medium level of innovativeness, medium farm decision making (63.20%) with medium achievement motivation (58.40%). About (55.20%) farmers had medium knowledge of farm enterprises with medium (71.20%) risk taking ability. The data revealed that 63.20 per cent had medium information seeking behaviour with low leadership ability (40.00%) and medium cosmopoliteness (56.80%). The overall study revealed that farmers had medium entrepreneurial behaviour. It could be observed that, six independent variables i.e . farming experience, education, land holding, annual income, assets and level of aspiration showed positive and significant relationship at 0.05 level of probability, whereas extension contact showed positive and significant relationship at 0.01 level of probability and three independent variables i.e. occupation, social participation and mass media use had non significant relationship with their entrepreneurial behaviour.
Bayesian BCJR for channel equalization and decoding

In this paper we focus on the probabilistic channel equalization in digital communications. We face the single input single output (SISO) model to show how the statistical information about the multipath channel can be exploited to further improve our estimation of the a posteriori probabilities (APP) during the equalization process. We consider not only the uncertainty due to the noise in the channel, but also in the estimate of the channel estate information (CSI). Thus, we resort to a Bayesian approach for the computation of the APP. This novel algorithm has the same complexity as the BCJR, exhibiting lower bit error rate at the output of the channel decoder than the standard BCJR that considers maximum likelihood (ML) to estimate the CSI
Welfare Effects of Endogenous Copyright Enforcement - the Case of Digital Goods

In case of digital goods such like music, intellectual property rights are typically not exerted by the creators (artists) but by intermediaries. Their profits, and therefore also the income of the artists, are endangered by copyright infringements (piracy). It is well known from static welfare analysis that to some extent piracy reduces the deadweight loss by limiting monopoly power and could therefore increase welfare. This paper contributes to the discussion by including the costs of law enforcement into the welfare analysis. Most models in the literature assume that law is enforced by governmental activities. In contrast, this paper considers that law enforcement is exerted by agents (e.g. lawyer chancellories, provider of screening technologies) which are also seen as intermediaries. The enforcement effort is therefore endogenously determined. It is shown that this will lead to suboptimal welfare outcomes. A social planner has to regulate punishment and enforcement effort to a moderate level. A more rigorous fight against piracy could only be justified by negative dynamic welfare effects due to a loss of creativity. However, there is no empirical evidence for that.
Presumed monozygotic twins develop following transfer of an in vitro-produced equine embryo

ABSTRACT An equine embryo produced by intracytoplasmic sperm injection (ICSI) was trans-cervically transferred to a recipient mare and pregnancy was confirmed via ultrasound examination on days 11, 12 and 15. On days 20 and 22, a single embryonic proper with a heartbeat was observed. On day 29, two embryos proper appeared during ultrasound examination, each possessing a heartbeat. Subsequent examinations on days 35 and 39 revealed continued viability and development of both embryos proper. On day 49, demise of both fetuses was present. Although no DNA analysis or post-partum examinations were performed, it is presumed that the fetuses were monozygotic twins based on membrane classification by ultrasound imaging as well as development occurring after the transfer of a single in vitro-produced embryo.
The S2E Platform: Design, Implementation, and Applications

This article presents S2E, a platform for analyzing the properties and behavior of software systems, along with its use in developing tools for comprehensive performance profiling, reverse engineering of proprietary software, and automated testing of kernel-mode and user-mode binaries. Conceptually, S2E is an automated path explorer with modular path analyzers: the explorer uses a symbolic execution engine to drive the target system down all execution paths of interest, while analyzers measure and/or check properties of each such path. S2E users can either combine existing analyzers to build custom analysis tools, or they can directly use S2E’s APIs. S2E’s strength is the ability to scale to large systems, such as a full Windows stack, using two new ideas: selective symbolic execution, a way to automatically minimize the amount of code that has to be executed symbolically given a target analysis, and execution consistency models, a way to make principled performance/accuracy trade-offs during analysis. These techniques give S2E three key abilities: to simultaneously analyze entire families of execution paths instead of just one execution at a time; to perform the analyses in-vivo within a real software stack---user programs, libraries, kernel, drivers, etc.---instead of using abstract models of these layers; and to operate directly on binaries, thus being able to analyze even proprietary software.
Local superfluidity of parahydrogen clusters.

We study by quantum Monte Carlo simulations the local superfluid response of small (up to 27 molecules) parahydrogen clusters, down to temperatures as low as 0.05 K. We show that at low temperature superfluidity is not confined at the surface of the clusters, as recently claimed by Khairallah et al. [Phys. Rev. Lett. 98, 183401 (2007)10.1103/PhysRevLett.98. 183401]. Rather, even clusters with a pronounced shell structure are essentially uniformly superfluid. Superfluidity occurs as a result of long exchange cycles involving all molecules.
Nonparametric inference for discretely sampled L\'evy processes

Given a sample from a discretely observed Levy process X = (Xt)t�0 of the finite jump activity, the problem of nonparametric estimation of the Levy density ρ corresponding to the process X is studied. An estimator of ρ is proposed that is based on a suitable inversion of the Levy-Khintchine formula and a plug-in device. The main results of the paper deal with upper risk bounds for estimation of ρ over suit- able classes of Levy triplets. The corresponding lower bounds are also discussed.
