Performance of CMS muon reconstruction in pp collision events at sqrt(s) = 7 TeV

Abstract: The performance of muon reconstruction, identification, and triggering in CMS has been studied using 40 inverse picobarns of data collected in pp collisions at sqrt(s) = 7 TeV at the LHC in 2010. A few benchmark sets of selection criteria covering a wide range of physics analysis needs have been examined. For all considered selections, the efficiency to reconstruct and identify a muon with a transverse momentum pT larger than a few GeV is above 95% over the whole region of pseudorapidity covered by the CMS muon system, abs(eta)<2.4, while the probability to misidentify a hadron as a muon is well below 1%. The efficiency to trigger on single muons with pT above a few GeV is higher than 90% over the full eta range, and typically substantially better. The overall momentum scale is measured to a precision of 0.2% with muons from Z decays. The transverse momentum resolution varies from 1% to 6% depending on pseudorapidity for muons with pT below 100 GeV and, using cosmic rays, it is shown to be better than 10% in the central region up to pT = 1 TeV. Observed distributions of all quantities are well reproduced by the Monte Carlo simulation.

A Longitudinal Study of Coronary Heart Disease

Abstract: Certain of the data accumulated over the course of more than 4 years in a prospective study of coronary heart disease being carried on in an industrial population have been presented. In a base population of 1,989 men, 88 cases of coronary heart disease have developed: angina pectoris, 47 men; myocardial infarction, 28 men; death from coronary, disease, 13 men. This approximates one case per 100 men per year. The development of clinical coronary heart disease has shown an association with early age of death of father, history of "noncardiac" chest discomfort, history of chronic cough, history of shortness of breath, history of peptic ulcer, presence of increased skinfold thickness, elevated blood pressure, AV nicking in the fundi, elevated blood cholesterol, ST and T abnormalities in the electrocardiogram, and use of cigarettes and coffee. No relation was encountered between body weight, mean blood sugar levels, lipoprotein lipase levels, or diet (other than coffee), and the development of coronary heart ...

Abandon Statistical Significance

Abstract: We discuss problems the null hypothesis significance testing (NHST) paradigm poses for replication and more broadly in the biomedical and social sciences as well as how these problems remain unreso
