ATLAS data quality operations and performance for 2015-2018 data-taking
2020
The ATLAS detector at the Large Hadron Collider reads out particle collision data from over 100 million electronic channels at a rate of approximately 100 kHz, with a recording rate for physics events of approximately 1 kHz. Before being certified for physics analysis at computer centres worldwide, the data must be scrutinised to ensure they are clean from any hardware or software related issues that may compromise their integrity. Prompt identification of these issues permits fast action to investigate, correct and potentially prevent future such problems that could render the data unusable. This is achieved through the monitoring of detector-level quantities and reconstructed collision ev…
Particle identification in ALICE: a Bayesian approach
2016
We present a Bayesian approach to particle identification (PID) within the ALICE experiment. The aim is to more effectively combine the particle identification capabilities of its various detectors. After a brief explanation of the adopted methodology and formalism, the performance of the Bayesian PID approach for charged pions, kaons and protons in the central barrel of ALICE is studied. PID is performed via measurements of specific energy loss ($\mathrm{d}E/\mathrm{d}x$) and time-of-flight. PID efficiencies and misidentification probabilities are extracted and compared with Monte Carlo simulations using high-purity samples of identified particles in the decay channels ${\rm K}^0_S \righta…

Grip Strength, Neurocognition, and Social Functioning in People WithType-2 Diabetes Mellitus, Major Depressive Disorder, Bipolar Disorder, and Schizo…
2020
[Background] Frailty is a common syndrome among older adults and patients with several comorbidities. Grip strength (GS) is a representative parameter of frailty because it is a valid indicator of current and long-term physical conditions in the general population and patients with severe mental illnesses (SMIs). Physical and cognitive capacities of people with SMIs are usually impaired; however, their relationship with frailty or social functioning have not been studied to date. The current study aimed to determine if GS is a valid predictor of changes in cognitive performance and social functioning in patients with type-2 diabetes mellitus and SMIs.
Effects of an incremental maximal endurance exercise stress-induced cortisol on cognitive performance
2019
Exercise; Cognitive functions; Cortisol Ejercicio físico; Funciones cognitivas; Cortisol Exercici físic; Funcions cognitives; Cortisol Objectives: It can be hypothesized that cognitive performance decreases after fatigue protocol when it coincides with the maximum peak of cortisol. The first aim of this study was to elucidate the effects of a single bout of high intensity exercise on behavioural (i.e., attention and memory) and physiological (i.e., salivary cortisol) responses. The second objective was to evaluate the effect of the performance of the cognitive tasks on cortisol levels. Methods: Thirty-four physically active men (at least 5 days/week of physical activity practice) 38.11 (1.5…
HUMAN SAFETY PERFORMANCE IN HIGH RELIABILITY ORGANIZATIONS: THE CASE OF THE NUCLEAR INDUSTRY
2018
Over the last few decades, the study of safety in high reliability organizations has not paid enough attention to the human role and its contribution to a reliable operation. Therefore, the literature about human safety performance is scarce and disjointed. The present paper integrates the existing knowledge on workers’ safety performance in high risk industries, specifically in the nuclear industry. In order to do this, we provide a literature review in which the concept of “safety performance” is clarified, and at the same time, we present the most recent research studies and models on this concept.
Limit on the diffuse flux of ultrahigh energy tau neutrinos with the surface detector of the Pierre Auger Observatory
2009
Data collected at the Pierre Auger Observatory are used to establish an upper limit on the diffuse flux of tau neutrinos in the cosmic radiation. Earth-skimming ντ may interact in the Earth's crust and produce a τ lepton by means of charged-current interactions. The τ lepton may emerge from the Earth and decay in the atmosphere to produce a nearly horizontal shower with a typical signature, a persistent electromagnetic component even at very large atmospheric depths. The search procedure to select events induced by τ decays against the background of normal showers induced by cosmic rays is described. The method used to compute the exposure for a detector continuously growing with time is de…
The Relationship Between Goal Orientation, Social Comparison Responses, Self-Efficacy, and Performance
2008
The present study examined whether social comparison responses (identification and contrast in social comparison) mediated the relationship between goal orientation (promotion and prevention) and self-efficacy, and whether self-efficacy was subsequently related with a better performance. As expected, the results showed that promotion-oriented individuals – who are focused on achieving success – had higher self-efficacy than prevention-oriented individuals – who are focused on avoiding failure. Only one of the social comparison responses had a mediating role. That is, the tendency to contrast oneself with others who were doing better mediated the relationship between a prevention goal orien…
