Enhancing Efficiency for Peer-to-Peer Traffic Locality : Measurement , Design and Future Trends

The fast-growing traffic of peer-to-peer (P2P) applications, most notably BitTorrent, is putting unprecedented pressure to Internet Service Providers (ISPs). P2P locality has therefore been widely suggested to mitigate the costly inter-ISP traffic. In this paper, we find that even in the most popular ASes (Autonomous Systems), very few individual torrents are able to form large enough local clusters of peers, making state-of-the-art locality mechanisms for individual torrents quite inefficient. Inspired by peers’ multiple torrent behavior, we develop a novel framework that traces and recovers the available contents at peers across multiple torrents, and thus effectively amplifies the possibilities of local sharing. We address some key design issues in this framework; in particular, we discuss the detection of peer migration and further explore the trends of improving peers’ incentive. We develop a smart detection mechanism with shared trackers, which achieves 45% success rate without any tracker-level communication overhead. Moreover, we also find that a number of BT swarms are now triggered by Social Network Services (SNS), such as Twitter, reflecting a new trend to provide better incentive for P2P traffic locality. Our trace-based simulation results indicate that our framework can successfully reduce the cross-ISP traffic and minimize the possible degradation of peers’ downloading experiences.
Impact of directionality on the extreme wave occurrence in a discrete random wave system

A number of marine accidents are possibly caused by encounters with the freak waves in the ocean. Numerous researches have therefore been conducted to understand, observe and predict the freak waves in the ocean, particularly in the last 10 years or so. Up until now, however, there is no monitoring system in operation that can detect the sporadic extreme events in the vast ocean. On the other hand, third generation wave models have advanced and are now in operation in various countries and institutions providing global and local wave forecasts. It is therefore practical to utilize numerical wave forecast products to predict freak wave occurrence in the ocean. The only practical suggestion made so far on the utilization of the wave forecast model to predict freak wave is the introduction of the Benjamin-Feir Index by Janssen (2003). The underlying principle is the near resonance interaction of waves that is inherent in the weakly nonlinear gravity wave system (Zakharov 1967). Janssen has shown by use of the Zakharov equation that the magnitude of the kurtosis can be parameterized by the ratio of wave steepness and spectral bandwidth. Because the simplest case of the non-resonant interaction was first discovered by Benjamin & Feir (1967) in their study of an unstable Stokes wave, the parameter was named the Benjamin-Feir index. The correspondence of the BFI to the extreme wave statistics was first verified experimentally by Onorato et al. (2004) where they have observed the evolution of a uni-directional random wave with JONSWAP type wave spectrum. Extreme wave statistics was controlled by changing the peakedness of the spectrum, effectively changing the frequency bandwidth or the BFI. Such discovery is a great step in understanding the freak wave generation mechanism, however, as the same authors (Onorato et al. 2002), and Soquet-Juglard et al. (2005) have shown numerically, the introduction of directionality of the wave spectrum significantly reduces the extreme wave occurrence. For this reason, there has been a debate whether near-resonance interaction or the bound-wave generation enhancing the extreme wave amplitude in a random Gaussian sea is responsible for the extreme wave generation in the open ocean. (Dysthe et al. 2004) In this study we extend the experimental work of Onorato et al. (2004) to include directionality of the JONSWAP type spectrum. The result is rather striking that the occurrence of extreme event significantly reduces as the directionality broadens. Preliminary analysis of a systematic experiment varying the directionality and the spectral bandwidth will be introduced in section 3, following the description of the wave tank in section 2. In section 4, the influence of discreteness of the wave system (that is inevitable in both tank and numerical experiments), will be addressed solving the Zakharov equation numerically. Conclusions follow.
Probabilistic Approach to a Class of Semilinear Partial Differential Equations

We discuss the recent progress about positive solutions of the semilinear equation ∆u = u in a domain, which has involved a combination of probabilistic and analytic methods. We emphasize the main ideas that have been used in the probabilistic approach. Special attention is given to the boundary trace problem, which consists in obtaining a one-to-one correspondence between the set of all solutions and a suitable set of admissible traces on the boundary. A few important open questions are also listed.
Theory Reviews - Hardware and Software Support for Testing Material on Specimens of the Small Cross Section

Testing techniques to obtain the mechanical properties of materials on specimens of the small cross section (miniature specimen) become the subject of numerous researches due to several advantages, in economic and organizational terms. This paper presents the model of the tensile testing device for materials on the specimens of the small cross section, its hardware and software basis. The device proved to be very reliable, so it is suitable for testing the mechanical characteristics of the material, just like the one used for the demonstration of material testing for students. © 2019 Published by Faculty of Engineering Corresponding author: Sonja Kostić Visoka tehnička škola strukovnih studija u Kragujevcu, Kosovska 8, Serbia.

ENSEMBLE SIMULATIONS OF RUPTURES ON ROUGH FAULTS : VARIABILITY IN RUPTURE PROCESS AND GROUND MOTION

Laboratory and field observations suggest that faults are self-similar surfaces with amplitude-to-wavelength ratios in the range of 10 to 10. Motivated by these observations, we study spontaneous rupture propagation and the resulting ground motion for hundreds of random realizations of rough faults. Simulation results show that roughness causes significant fluctuations in rupture velocity and induces short-wavelength slip heterogeneity, which excite seismic waves over a broad range of wavelengths and result in an approximately ω far-field displacement spectra. The remarkable similarity between the synthetic and observed seismograms suggests that rupture propagation on randomly generated self-similar faults could be a new and self-consistent way to generate synthetic ground motions that avoids the need to artificially combine deterministic low frequency simulations with stochastic high frequency time series. We also find that the rupture process can be rather complicated: bursts of supershear rupture occur on favorably oriented fault sections; occasionally, ruptures reverse their propagation direction and rupture a fault patch twice in a single event; sometimes, ruptures stop at geometrical barriers for seconds and then initiate again, all of which add complexities to ground motion predictions. We further use the representation theorem to calculate far-field body wave seismograms and Fourier spectra. For primarily unilateral ruptures, far-field radiation patterns change from a distinct double couple pattern with strong directivity effects at low frequencies to a more isotropic pattern with diminished directivity effects at high frequencies, suggesting that in addition to scattering along the wave propagation path, source effects may also be responsible for the observed frequency dependence of directivity effects.
Investigating the Possible Relationship between Multiple Intelligences and Self-efficacy : The Case of Iranian EAP Instructors

The current study aimed to investigate the possible relationship between Iranian English for academic purposes (EAP) instructors’ interpersonal and intrapersonal intelligences and their self-efficacy beliefs. To this end, 120 language and content English for academic purposes instructors were asked to complete the excerpted items from McKenzie’s (1990) Multiple Intelligences Questionnaire and Tschannen-Moran and Woolfolk Hoy’s (2001) Teachers’ Sense of Efficacy Scale. The results of the Pearson product-moment correlation showed that there was a positive significant correlation between personal intelligences and self-efficacy. Furthermore, using an independent t-test, the researchers found that there was no significant difference among language and content instructors regarding their self-efficacy beliefs in EAP classrooms. Moreover, the results of a paired t-test revealed that language instructors would feel more efficacious in English for general purposes than in EAP classrooms. The conclusions and implications of the current study are discussed in light of the earlier findings.
DEMOCRACY AND ECONOMIC GROWTH : EVIDENCE FROM EMERGING MARKET ECONOMIES

It is believed that wealth of countries also increases as the level of democratization increases, vice versa. Effects of democracy on the economic structure have been discussed for a long time. In economic growth literature, it can be seen that the effect of democracy has been frequently examined within the scope of economic growth. But, it can be seen that there is no consensus in studies on relationship between democracy and economic growth. In the present study, the effect of democracy on the economic growth was examined via panel data method by using 1972-2016 annually data of 8 emerging market economies. During the analyses, the real GDP represented the economic growth and Freedom House freedom index represented the level of democracy. In this study, the cross sectional dependency was tested using CDLM1 and CDLMadj, stationarity of series by using CADF unit root test, and long-term relationships by using Westerlund and Edgerton (2007) cointegration test and long-term relationship was found between the series. The coefficients were estimated using Panel AMG method. The findings indicated that the increase in level of democracy affected the economic growth positively in some countries and negatively in some other countries. Moreover, the causality between the variables was examined by using the test of Emirmahmutoğlu and Köse (2011). Bidirectional causality was observed in most of panel. According to the results, it was found that the increase in democratization level in Brazil, Chile, India, and Turkey positively affected the economic growth. But, in Argentina, China, Indonesia, and South Africa, the increase in democratization level has negative effects on the economic growth. In * Dr. Öğr.

KRAS and BRAF mutations limit the benefit of liver resection in etastatic colorectal cancer patients ? A systematic review and eta-analysis

Background: Clinical trials investigated the potential role of both KRAS and BRAF mutations, as prognostic biomarkers, in colorectal cancer (CRC) patients who underwent surgical treatment of CRC-related liver metastases (CLM), showing conflicting results. This meta-analysis aims to review all the studies reporting survival outcomes (recurrence free survival (RFS), and/or overall survival (OS)) of patients undergoing resection of CLM, stratified according to KRAS and/or BRAF mutation status. Materials and methods: Data from all published studies reporting survival outcomes (RFS and/or OS) of CRC patients who received resection of CLM, stratified by KRAS and/or BRAF mutation status were collected, according to the PRISMA guidelines. Pooled HRs were calculated for both the OS and/or RFS. Results: Seven eligible trials (1403 patients) were included. Pooled analysis showed that KRAS mutaolorectal cancer tions predicted a significantly worse both RFS (HR: 1.65; 95% CI: 1.23–2.21) and OS (HR: 1.86; 95% CI: 1.51–2.30) in patients who underwent surgical resection of CLM. BRAF mutations were also associated with a significantly worse OS (HR: 3.90; 95% CI: 1.96–7.73) in this subgroup of patients. Conclusions: This meta-analysis suggests both KRAS and BRAF mutations as poor, prognostic biomarkers, associated with worse survival outcomes, in patients undergoing hepatic resection of CLM. © 2016 Elsevier Ireland Ltd.

Identification and pathogenicity of Graphium and Pesotum species from machete wounds on Schizolobium parahybum in Ecuador

Schizolobium parahybum is native to Ecuador and is widely distributed throughout South America. This tree has ideal timber properties and is a favored species for plantation development. Schizolobium parahybum trees, however, suffer from a serious disease that causes substantial losses to plantations in Ecuador. Most diseased trees have been regularly wounded with machetes and it has been suggested that these wounds might provide entry portals for pathogens. To determine the possible role that fungi associated with machete wounds might play in disease development, wood samples were taken from these wounds and screened for possible pathogens. A number of potential pathogens were identified, including Ceratocystis fimbriata, C. moniliformis, Graphium spp. and Pesotum spp. The objective of this study was to identify the twenty-one synnematous Hyphomycetes, from wounds on S. parahybum, using small subunit (SSU) and internal transcribed spacer (ITS) sequence data from the ribosomal RNA operon. We also investigated the possible role of these species in disease development in a greenhouse inoculation trail. Results showed that fifteen isolates reside in the Graphium penicillioides complex (Order: Microascales). Four isolates resided in the Ophiostomatales and represent the Pesotum anamorph of Ophiostoma quercus. The remaining two isolates were unidentified Pesotum anamorphs of Ophiostoma. None of the three species produced significant lesions in a greenhouse inoculation trail and we do not consider them pathogens of S. parahybum.
238 Language and Speech 59 ( 2 ) 2 A comparison of voicing and voicing alternations in Dutch and German

The voicing contrast is neutralized syllable and word finally in Dutch and German, leading to alternations within the morphological paradigm (e.g., Dutch ‘bed(s)’, be[t]-be[d]en, German ‘dog(s)’, Hun[t]-Hun[d]e). Despite structural similarity, language-specific morphological, phonological and lexical properties impact on the distribution of this alternation in the two languages. Previous acquisition research has focused on one language only, predominantly focusing on children’s production accuracy, concluding that alternations are not acquired until late in the acquisition process in either language. This paper adapts a perceptual method to investigate how voicing alternations are represented in the mental lexicon of Dutch and German 3-year-olds. Sensitivity to mispronunciations of voicing word-medially in plural forms was measured using a visual fixation procedure. Dutch children exhibited evidence of overgeneralizing the voicing alternation, whereas German children consistently preferred the correct pronunciation to mispronunciations. Results indicate that the acquisition of voicing alternations is influenced by language-specific factors beyond the alternation itself.

The Effect of Counterproductive Work Behavior (CWB) And Organizational Citizenship Behavior (OCB) on Employee Performance With Employee Engagement As Intervening Variable

The purpose of this research is to test the predictive model of the influence of Counterproductive Work Behavior (CWB) and Organizational Citizenship Behavior (OCB) on Employee Performance (EP) with Employee Engagement (EE) as intervening variable. Surveys are conducted by researchers in order to find answers to corruption that undermine the performance of the organization. The population includes all employees working in organization X in 2016. The total number (107) is selected as a sample. For analysts Pearson correlation research results, multiple regression and path equation modeling techniques with software SPSS 19 with a confidence level of 95%. The results showed a significant relationship between OCB, CWB and EE on PE. It is evident that the greater the OCB, the more influential the EE is. The magnitude of the influence of OCB on EE indirectly also affect the large PE also. The opposite occurs when CWB increases, CWB will have a negative impact on PE. The impact of employees who have high Engagement Employee performance souls, influences the high PE. when compared to individuals who do not have an EE. Similarly, high Engagement Employee CWB will have a negative impact on performance will decrease. So EE is able to increase the influence of OCB on PE and EE able to suppress CWB to PE.
Robust H ∞ Fuzzy Filtering for a Class of State-Delayed Nonlinear Systems in an LMI Setting

— The problem of H∞ filtering design for a class of nonlinear systems with time-delay via TakagiSugeno fuzzy models is investigated in this paper. Sufficient conditions for the existence of a stable nonlinear filter assuring global asymptotic stability and a prescribed H∞ noise attenuation level to the filtering error are established in terms of linear matrix inequalities. Moreover, it is shown how to consider the proposed approach to deal with uncertain parameters or systems without delay. Finally, a discrete-time nonlinear system with timedelay is investigated as a numerical example.

Effectiveness of essential oils from Ngaoundere, against post-harvest insect and fungal pests of maize: Poster

Successful storage of harvest is a matter of utmost importance in the Sudano-Guinean agro-ecological zone where intense cultivation takes place only once a year. Poor and rudimentary drying/storage methods, high relative humidity as well as inaccessibility to the chemical pesticides leave stored maize at the mercy of insect and fungal attack. Insect attack favours secondary attack by fungi; both leading to a fall in the nutritional, sanitary and organoleptic qualities of the stored maize. Thus, poor peasant farmers are left with the choice of locally available botanicals as alternatives to chemical pesticides. It is against this backdrop that this study seeks to determine the insecticidal efficacy of essential oils from the leaves of Chenopodium ambrosioides and Cupressus sempervirens together with their 50/50 binary combination against the maize weevil, Sitophilus zeamais, and the fungi: Rhizopus stolonifer and Aspergillus flavus on stored maize. Insect mortality and progeny inhibition and the inhibition of fungal invasion were evaluated. Pesticidal activities of both essential oils increased with ascending dose of application. 200 µL/kg of the binary combination caused 100% mortality within 14 days and it completely inhibited progeny production in the weevil. The mixture of the two oils showed additive effects against the weevils and fungi. The two essential oils in isolation significantly inhibited fungal spore invasion in 21 days of storage although A. flavus was less susceptible than R. stolonifer. Therefore both plants could provide active botanical pesticides against S. zeamais and fungal pests in stored maize.
Sweeting, H. and West, P. (2001) Being different: correlates of the experience of teasing and bullying at age 11. Research Papers in Education 16(3):pp. 225-46. http://eprints.gla.ac.uk/archive/00002724/ BEING DIFFERENT: CORRELATES OF THE EXPERIENCE OF TEASING AND BULLYING AT AGE

The public stereotype, largely supported by a rather diverse range of literature, is that bullied children differ from their peers in respect of attributes such as appearance, disability or school performance. In this paper we explore the characteristics of such victims in a way which is both more comprehensive than previous studies and in addition, considers and accounts for possible interrelationships between variables. Self-report data on teasing and bullying (found to be strongly inter-related) were obtained from a large, school-based sample of 11 year olds, with additional descriptions and ratings of the children from their parents, class teachers and nurses. Experience of teasing/bullying did not differ according to race, physical maturity or height, but was more likely among children who were less physically attractive, overweight, had a disability such as a sight, hearing or speech problem, and performed poorly at school. These factors were not only significant regardless of sex and social class, but also independent and thus additive in their effects. Characteristics of appearance, disability or ability which in themselves may be difficult to deal with also increase the likelihood that a child will experience the additional burden of being bullied.
