Cross-section-constrained top-quark mass measurement from dilepton events at the tevatron
2008
We report the first top quark mass measurement that uses a cross section constraint to improve the mass determination. This measurement is made with a dilepton $t\bar{t}$ event sample collected with the CDF II detector. From a data sample corresponding to an integrated luminosity of 1.2 fb$^{-1}$, we measure a top quark mass of $\rm{170.7^{+4.2}_{-3.9}(stat)\pm2.6(syst)}$ $\rm{\pm2.4(theory) GeV/{\it{c}}^{2}}$. The measurement without the cross section constraint results in a top quark mass of $\rm{169.7^{+5.2}_{-4.9}(stat)\pm3.1(syst) GeV/{\it{c}}^{2}}$.
Combination of D0 measurements of the top quark mass
2017
We present a combination of measurements of the top quark mass by the D0 experiment in the lepton+jets and dilepton channels. We use all the data collected in Run I (1992--1996) at $\sqrt s=1.8$ TeV and Run II (2001--2011) at $\sqrt s=1.96$ TeV of the Tevatron $p \bar{p}$ collider, corresponding to integrated luminosities of 0.1 fb$^{-1}$ and 9.7 fb$^{-1}$, respectively. The combined result is: $m_t = 174.95 \pm0.40\,{\rm(stat)} \pm 0.64\,{\rm(syst)}\,{\rm{GeV}}=174.95 \pm 0.75 \, {\rm{GeV}}$.
The Efficacy and Safety of Topiramate in the Prevention of Pediatric Migraine: An Update Meta-Analysis
2020
Background: Migraine is the most common acute primary headache in children and adolescents. In 2014, topiramate became the first preventive drug for migraine, approved by the Food and Drug Administration (FDA) for adolescents. This meta-analysis was aimed to evaluate the efficacy and safety of topiramate in the prevention of pediatric migraine.Methods: We searched the PubMed, EMBASE, Cochrane Library, and Chinese National Knowledge Infrastructure (CNKI) databases up to June 2019 for eligible randomized controlled trials (RCTs). The primary outcomes were mean migraine days per month, ≥50% reduction rate, and Pediatric Migraine Disability Assessment Scale (PedMIDAS) scores. RevMan5.3 software…
Nitrogen isotope evidence for stepwise oxygenation of the ocean during the Great Oxidation Event
2019
24 pages; International audience; The Earth’s oxygenation represents one of the most important environmental drivers of life’s evolution, with the first rise, known as ‘the Great Oxidation Event’ (GOE), corresponding to unpreceded accumulation of atmospheric O2, changes in the flux of marine nutrients and possibly global glaciations. However, the detailed evolution of the GOE is still debated, as for instance the accumulation trends of oceanic versus atmospheric oxygen and the nature of biogeochemical responses to oxygenation. Here, we combine organic carbon and bulk nitrogen isotope compositions with major element concentrations and iron speciation data of sedimentary rocks recovered from …
Challenges of tourism development in winter sports destinations and for post-event tourism marketing: the cases of the Ramsau Nordic Ski World Champi…
2013
Previous research on winter sport destinations which have hosted big sport events suggested that there is a gap between the relevance of the systematic considerations of the specific challenges of tourism destination marketing and common practice. The study therefore investigates through individual interviews with key stakeholders (1) the level of agreement with central theoretical statements among stakeholders and key decision-makers at the Austrian destinations Ramsau (a traditional Nordic destination) and St Anton (a traditional Alpine destination) and (2) the relevance of this knowledge to the practical work of the key decision-makers at the destinations. The results show that there is …
Contextual engagement in event visitors’ experience and satisfaction
2021
This paper aims to advance the understanding of the experience-satisfaction relationship and the impact of the event context on such a relationship. In particular, there is an interplay between fou...
monitoraggio della funzionlità renale in un gruppo di soggetti esposti a rischi chimico
2007
Nei lavoratori esposti a rischio chimico la sorveglianza sanitaria risulta strumento indispensabile nella prevenzione delle malattie professionali. A tal proposito il nostro studio si è rivolto in particolare alla individuazione di eventuali effetti nefrolesivi precoci attraverso un protocollo clinico e di esami di laboratorio specifici . The sanitary monitoring is an unavoidable instrument to prevent professional diseases in those workers exposed to che - mical risks. Our study has been carried out in order to focus possible precocious nephro-detrimental effects, thanks to a clinic proce - dure and several specific laboratory exams.
Distraction of cyclists: how does it influence their risky behaviors and traffic crashes?
2018
BackgroundUndisputedly, traffic crashes constitute a public health concern whose impact and importance have been increasing during the past few decades. Specifically, road safety data have systematically shown how cyclists are highly vulnerable to suffering traffic crashes and severe injuries derived from them. Furthermore, although the empirical evidence is still very limited in this regard, in addition to other human factors involved in cycling crashes, distractions while cycling appear to be a major contributor to the road risk of cyclists.ObjectivesThe main objectives of this study were, first, to explore the prevalence and trends of cycling distractions within an international sample o…
Efficacy and cost-effectiveness of guided and unguided internet- and mobile-based indicated transdiagnostic prevention of depression and anxiety (ICa…
2019
Background Depression and anxiety are highly prevalent and often co-occur. Several studies indicate the potential of disorder-specific psychological interventions for the prevention of each of these disorders. To treat comorbidity, transdiagnostic treatment concepts seem to be a promising approach, however, evidence for transdiagnostic concepts of prevention remains inconclusive. Internet- and mobile-based interventions (IMIs) may be an effective means to deliver psychological interventions on a large scale for the prevention of common mental disorders (CMDs) such as depression and anxiety. IMIs have been shown to be effective in treating CMDs, e.g. in reducing symptoms of depression and an…
