Envelope: estimation of bottleneck and available bandwidth over multiple congested links
No full textBandwidth estimation has been extensively researched in the past. The majority of existing methods assume either negligible or fluid cross-traffic in the network during the analysis. However, on the present-day Internet, these assumptions do not always hold right. Hence, over such paths the existing bandwidth estimation techniques become inaccurate. In this thesis, we explore the problem assuming arbitrary cross-traffic and develop a new probing method called Envelope, which can simultaneously estimate bottleneck and available bandwidth over an end-to-end path with multiple heavily congested links. Envelope is based on a recursive extension of the stochastic queuing model first proposed by Kang, Liu, Dai and Loguinov (2004), and a modified packet-train methodology. We use two small packets to surround the probing packet-trains and preserve the inter-packet spacing of probe traffic at each router in the path-suffix. The preserved spacings are then used by the receiver to estimate bandwidth. We first reproduce results for a single congested router case using the model proposed by Kang et al. Next, we extend it to the case of multiple congested routers with arbitrary cross-traffic and develop the methodology Envelope. We evaluate the performance of Envelope in various network path topologies and cross-traffic conditions through extensive NS-2 simulations. We also evaluate various probe-traffic parameters which affect the accuracy of this method and obtain the range of values for these parameters that provide good estimation results. Finally, we compare the bandwidth estimation results of our method with the results of other existing methods such as IGI (2003) , Spruce (2003), Pathload (2002), and CapProbe (June 2004) using simulation in Network Simulator (NS-2) with varied network topologies and cross-traffic
Overcoming Recession through Effective Business Communication Approaches (A Study in Indian Scenario)
No full textNo business activity can be completed without effective business communication network. The stage of economic turmoil is the most important time for any organization to regroup its strategy. At this juncture, strong, transparent and constant internal and external communication networks play a vital role. The global meltdown is a blessing in disguise for the organizations to invigorate their business communication network. The present paper aims to study multifarious approaches of Business Communication applied by Indian Organizations to combat the turbulent period of recession in a successful manner.
Learning from multiple analogies: an Information Theoretic framework for predicting criminal recidivism
No full textIf recidivism is defined as rearrest within a finite period following release from prison, then the kinds of outcomes typically available to researchers include: (i) whether or not the individual was rearrested within the follow-up period; (ii) how many times the individual was rearrested; and (iii) what was the duration from release to first (or subsequent) rearrest. Since these outcomes are all different manifestations of the same underlying stochastic process, they provide multiple analogies from which to recover information about it. This paper develops a semi-parametric approach for utilizing information in these, and several other related outcomes, to predict criminal recidivism and presents preliminary findings.information theory; criminal recidivism; predictive modeling; multiple analogies
Measuring (KSK +/-)-K-0 interactions using Pb-Pb collisions at root S-NN=2.76 TeV
No full textWe present the first ever measurements of femtoscopic correlations between the K-S(0) and K-+/- particles. The analysis was performed on the data from Pb-Pb collisions at root S-NN = 2.76 TeV measured by the ALICE experiment. The observed femtoscopic correlations are consistent with final-state interactions proceeding via the a(0)(980) resonance. The extracted kaon source radius and correlation strength parameters for (KSK-)-K-0 are found to be equal within the experimental uncertainties to those for (KSK+)-K-0. Comparing the results of the present study with those from published identical-kaon femtoscopic studies by ALICE, mass and coupling parameters for the a(0) resonance are tested. Our results are also compatible with the interpretation of the a(0) having a tetraquark structure instead of that of a diquark. (c) 2017 The Author. Published by Elsevier B.V
Quality of reporting in interventional neuroradiology case series: a meta-epidemiological analysis and recommendations for improving reporting
No full textPosterInterventional neuroradiology is a dynamic field with technological advancements constantly driving evolution in clinical practice. Case series provide interventional neuroradiologists the opportunity to describe the clinical implications of novel equipment and techniques almost in real-time, informing broader adoption and directing future research. Complete reporting in case series is vital in enabling readers to detect bias, determine the generalisability of results and replicate study methodology[1-4]. The purpose of this meta-epidemiological analysis was to assess the quality of reporting in interventional neuroradiology case series and develop recommendations for improved reporting. Due to the significant volume of published interventional neuroradiology case series, adherence to the Preferred Reporting of CasE Series in Surgery 2020 (PROCESS 2020) guideline[5] amongst series describing endovascular management of vein of Galen malformation was selected as a case study.S.

Let’s talk mental health: analysis of Indian immigrant women’s culturally centered mental health perceptions and identifying modifiers in interventions
No full textDoctor of PhilosophyLeadership Communication Interdepartmental ProgramNancy W. MuturiMental health problems such as depression and anxiety are common among immigrant groups in the United States. Differences in cultural values and practices inform the variety of mental health perceptions and behaviors. Negative perceptions and barriers persist among Indian immigrant women due to stigma and fear of judgment. Although previous research has documented the prevalence of mental health diseases among Indian immigrant women, there is a limited understanding of the role of Indian culture in influencing perceptions and help-seeking behaviors. This hinders improvement in interventions and campaigns for cultural communities. To fill these gaps, this health communication research aimed to develop a thorough understanding of how culture shapes mental health perceptions and help-seeking behaviors among Indian immigrant women and to elicit recommendations for enhancement in the current intervention from community mental health experts. Using Hofstede’s cultural determinants theory, culture-centered approach, and collective leadership as a theoretical framework, this study employed a hermeneutic phenomenological approach using in-depth semi-structured interviews among Indian immigrant women and focus group discussion among mental health experts.
Findings indicated that the Indian culture negatively influences perceptions and behaviors among Indian immigrant women. Masculinity, collectivism, high power distance, and uncertainty avoidance restrict women’s mental health expression and ability to seek help. Further, Indian immigrant women’s lived experiences, along with cultural and social factors, shape their perceptions. Additionally, acculturative experiences hinder mental well-being but also improve Indian immigrant women’s outlook on diseases and treatments. These women also perceive contextual and cost-related barriers while also facing difficulty in communicating about mental health due to a lack of awareness and openness among other Asian Indians. To address these challenges, mental health experts elicited recommendations for mental health experts to be proactive in the immigrant communities. They also provided enhancement opportunities for universities to improve their accessibility for international and immigrant communities and train future therapists to become more culturally attuned. Additionally, cultural ambassadorship must be adopted to reach immigrant communities through leaders. The theoretical and practical implications of this research are highlighted in the study. The study suggests further research in understanding the role of culture in mental health topics among minority groups with the use of culture-centered approach that can accentuate development in health interventions. It provides avenues for social change scholarship in health topics that can look beyond Western biomedicine. The study concludes by presenting an overview of the completion of research goals
Integrated ecosystems approach for sustainable intensification of community based silvopatoral systems in arid western Rajasthan, India: implications for upscaling
No full textThe common pastures in arid Rajasthan, India though are critically important for sustaining livestock dominant smallholder rural livelihoods and ecosystems services, but have been severely degraded due to several factors. Among others, the stakeholders’ perception of low returns on any investment of time or other resources for restoring these degraded common property resources (CPRs) is resulting into their continuous neglect. Generating sufficient on-farm evidence of enhanced biomass productivity and returns from CPRs employing integrated natural resource management and appropriate governance mechanisms are suggested strategies for enhancing community participation and influencing policies for their sustainable development. The present study aims to understand the key drivers of CPRs management and assess the potential of sustainable intensification of community silvo-pastoral systems for increased biomass production and returns in arid western Rajasthan, India. The study was undertaken in Jodhpur, Barmer and Jaisalmer districts across the annual rainfall gradient from 170 mm to 280 mm. The case-study analyses and the group-discussions were used as a starting point for facilitated community elaborations on how to adopt appropriate by-laws and identify opportunities and challenges of sustainable intensification of community pastures. Action-sites of 10 ha degraded common pastures were identified in each of the three communities to test silvo-pastoral rehabilitation options. Participatory Mozer-framework matrix accounted for local preferences and climate in selecting the plant species. The community was involved in in-situ and ex-situ water and soil conservation, species selection and monitoring, fencing, cut and carry systems and output sharing. The biomass assessment with respect to yield, species diversity, share of edible and non-edible species was carried out in pasture and control plots. The integrated ecosystems approach for rehabilitation of severely degraded community silvo-pastoral systems under arid region resulted in many-fold increase in biomass yield from 0.25-0.40 t/ha to 1.6–4.6 t/ha in the second year. The proportion of edible species increased from 15 -24% to 55 – 73%. The ex-ante analysis for a 10 year time horizon indicates payback period of about three years and over 30% IRR. Paper explores the potential to upscale the approach to at least one quarter of the common lands in west Rajasthan (1 m ha) producing about 2.5 million tons additional biomass. The study highlights the role of the structure and functions of the production system as well as social ecological system in designing appropriate NRM interventions, species selection, grazing system, market integration and institutional mechanisms
K*(892)0 and φ(1020) meson production at high transverse momentum in pp and Pb-Pb collisions at sNN=2.76 TeV
No full textThe production of K∗(892)0 and φ(1020) mesons in proton-proton (pp) and lead-lead (Pb-Pb) collisions at sNN=2.76TeV has been analyzed using a high luminosity data sample accumulated in 2011 with the ALICE detector at the Large Hadron Collider (LHC). Transverse momentum (pT) spectra have been measured for K∗(892)0 and φ(1020) mesons via their hadronic decay channels for pT up to 20GeV/c. The measurements in pp collisions have been compared to model calculations and used to determine the nuclear modification factor and particle ratios. The K∗(892)0/K ratio exhibits significant reduction from pp to central Pb-Pb collisions, consistent with the suppression of the K∗(892)0 yield at low pT due to rescattering of its decay products in the hadronic phase. In central Pb-Pb collisions the pT dependent φ(1020)/π and K∗(892)0/π ratios show an enhancement over pp collisions for pT≈3GeV/c, consistent with previous observations of strong radial flow. At high pT, particle ratios in Pb-Pb collisions are similar to those measured in pp collisions. In central Pb-Pb collisions, the production of K∗(892)0 and φ(1020) mesons is suppressed for pT>8GeV/c. This suppression is similar to that of charged pions, kaons, and protons, indicating that the suppression does not depend on particle mass or flavor in the light quark sector
Production of K∗ (892) 0 and ϕ(1020) in p–Pb collisions at √sNN = 5.02 TeV
No full textThe production of K∗(892)0 and ϕ(1020) mesons has been measured in p–Pb collisions at √sNN = 5.02 TeV. K∗0 and ϕ are reconstructed via their decay into charged hadrons with the ALICE detector in the rapidity range −0.5<y<0. The transverse momentum spectra, measured as a function of the multiplicity, have a pT range from 0 to 15 GeV/c for K∗0 and from 0.3 to 21 GeV/c for ϕ. Integrated yields, mean transverse momenta and particle ratios are reported and compared with results in pp collisions at s√ = 7 TeV and Pb–Pb collisions at √sNN = 2.76 TeV. In Pb–Pb and p–Pb collisions, K∗0 and ϕ probe the hadronic phase of the system and contribute to the study of particle formation mechanisms by comparison with other identified hadrons. For this purpose, the mean transverse momenta and the differential proton-to-ϕ ratio are discussed as a function of the multiplicity of the event. The short-lived K∗0 is measured to investigate re-scattering effects, believed to be related to the size of the system and to the lifetime of the hadronic phase.peerReviewe
