Abstract: The production of prompt D+s mesons was measured for the first time in collisions of heavy nuclei with the ALICE detector at the LHC. The analysis was performed on a data sample of Pb-Pb collisions at a centre-of-mass energy per nucleon pair, √sNN, of 2.76 TeV in two different centrality classes, namely 0–10% and 20–50%. D+s mesons and their antiparticles were reconstructed at mid-rapidity from their hadronic decay channel D+s → φπ+, with φ → K−K+, in the transverse momentum intervals 4 < pT < 12 GeV/c and 6 < pT < 12GeV/c for the 0–10% and 20–50% centrality classes, respectively.

Connection Service Providers (CSP) are wishing to increase their Return on Investment (ROI) by utilizing the data assets generated by tracking subscriber behaviors. This results in the ability to apply personalized policies, monitor and control the service traffic to subscribers and gain more revenue through the usage of subscriber data with ad networks. In this paper, a system is proposed to monitor and analyze the Internet access of the subscribers of a regional SP in order to classify the subscribers into interest categories from the Interactive Advertising Bureau (IAB) categories.

We report on the first measurement of an excess in the yield of J=ψ at very low transverse momentum (pT < 0.3 GeV=c) in peripheral hadronic Pb-Pb collisions at sNN 1⁄4 2.76 TeV, performed by ALICE at the CERN LHC. Remarkably, the measured nuclear modification factor of J=ψ in the rapidity range 2.5 < y < 4 reaches about 7 (2) in the pT range 0–0.3 GeV=c in the 70%–90% (50%–70%) centrality class. The J=ψ production cross section associated with the observed excess is obtained under the hypothesis that coherent photoproduction of J=ψ is the underlying physics mechanism. If confirmed, the observa ...Daha fazlası

The synthesis of derivatives of dithionepyrrole is a hot subject that has been studied extensively. In this study, a novel approach for constructing different glucose biosensors using conducting polymers of 4-(4H-dithyinol[3,2-b:2′,3′-d]pyroll-4-yl)aniline and 4-(4H-dithyinol[3,2-b:2′,3′-d]pyroll-4-yl)-[1,1′-biphenyl]-4-amine is proposed. After the synthesis and characterizations of the dithionepyrrole type monomers, they were used in glucose biosensing applications. The surface of gold electrode was modified with mercaptoethane sulfonic acid and p-aminothiophenol functionalized gold nanoparti ...Daha fazlası

Introduction: Helicobacter pylori (H. pylori) infection is common throughout the world. Ghrelin and leptin peptides play a crucial role in the homeostasis of the human body. Previously, some studies showed that H. pylori colonization had been associated with circulating leptin and ghrelin levels, but the certain relationship is still uncertain. The goal of this study is to determine the effects of H. pylori infection on serum ghrelin and leptin levels and how these relates to body weight changes before and after H. pylori eradication. Materials and methods: This study prospectively enrolled 12 ...Daha fazlası
The elliptic, triangular, quadrangular and pentagonal anisotropic flow coeffi- cients for π±, K± and p+p in Pb-Pb collisions at √sNN = 2.76 TeV were measured with the ALICE detector at the Large Hadron Collider. The results were obtained with the Scalar Product method, correlating the identified hadrons with reference particles from a different pseudorapidity region. Effects not related to the common event symmetry planes (non-flow) were estimated using correlations in pp collisions and were subtracted from the measure- ment. The obtained flow coefficients exhibit a clear mass ordering for tra ...Daha fazlası
Quality Function Deployment (QFD) is a method developed in the 1970’s in Japan by Dr. Yoji Akao and with later contributions of Shigeru Mizuno. QFD is adopted all over the world following a number of successful applications in Japan and has been applied very widely until today. This term has been translated to English as "Quality Function Deployment" from original Japanese name "Ten Kai Hin Shits Ki No". The most basic purpose of QFD is to design the functions which product performs according to the needs and requirements of customers. The aim of this study is to apply QFD in a university in T ...Daha fazlası
The production of the hypertriton nuclei 3ΛH and 3Λ¯ has been measured for the first time in Pb–Pb collisions at √sNN = 2.76 TeV with the ALICE experiment at LHC. The pT-integrated 3 !H yield in one unity of rapidity, dN/dy × B.R. ! 3 !H→3He,π−" = (3.86 ± 0.77(stat.) ± 0.68(syst.)) × 10−5 in the 0–10% most central collisions, is consistent with the predictions from a statistical thermal model using the same temperature as for the light hadrons. The coalescence parameter B3 shows a dependence on the transverse momentum, similar to the B2 of deuterons and the B3 of 3He nuclei. The ratio of yield ...Daha fazlası
The 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, mea- sured 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. Inte- grated 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 pr ...Daha fazlası
