Psychobiological Changes during National Futsal Team Training Camps and Their Relationship with Training Load
(MDPI, 2020-03-02)The aim of this study was two-fold: (1) to analyze the within-week variations of heart rate, session-rated of perceived exertion (sRPE), total distance, distance in 8.0-11.99 km/h(-1), recovery distance in 12.0-17.99 ... -
Psychological well-being related to screen time, physical activity after school, and weight status in Chilean schoolchildren
(ARAN EDICIONES, S L, 2019)Background: the relationship between physical activity (PA) patterns and mental health in children is receiving considerable attention. Aims: the aim of this study was to compare psychological well-being in groups of ... -
Psychometric properties of the Spanish version of the Edinburgh Handedness Inventory in a sample of Chilean undergraduates
(ACADEMIC PRESS INC ELSEVIER SCIENCE, 2019)An individual's nervous and cognitive systems are lateralized, and handedness represents a behavioral manifestation of such organization. Therefore, accurately and reliably measuring handedness has repercussion on our ... -
PT-symmetric phonon laser under gain saturation effect
(The Optical Society, 2020-07-20)As an analog of optical laser, phonon laser has potential applications in various areas. We study a type of phonon laser implemented by two coupled micro-cavities, one of which carries optical gain medium. The phonon laser ... -
Pubertal development at age 14 is associated with male adolescents' combustible cigarette smoking and dual use, but not with e-cigarette use - Findings from the UK Millennium Cohort Study
(ELSEVIER IRELAND LTD, 2023-12-01)Background: Adolescent nicotine exposure via electronic cigarettes (e-cigarettes) is a global health concern. Pubertal development earlier than peers increases the risk of tobacco smoking compared to peers experiencing ... -

Purification of Exosomes from Primary Schwann Cells, RNA Extraction, and Next-Generation Sequencing of Exosomal RNAs
(Humana Press, 2018)Exosomes are small (30-150 nm) vesicles of endosomal origin secreted by most cell types. Exosomes contain proteins, lipids, and RNA species including microRNA, mRNA, rRNA, and long noncoding RNAs. The mechanisms associated ... -
Quality of life, physical fitness and self-esteem and nutritional status in adolescents and their relationship with academic performance
(Chile. Universidad Mayor, 2019)Academic performance (AP) is conditioned by several factors and the self-esteem and health related to quality of life (HRQoL) are influential factors. The objective of the research was to determine the association between ... -
Quantifying phonon-induced non-Markovianity in color centers in diamond
(AMER PHYSICAL SOC, 2020)We propose the application of a coherence-based measure for non-Markovianity to study the dynamics of color centers in diamond, where the optical coherence between two orbital states is affected by interactions with a ... -
Quantum Discord, Thermal Discord, and Entropy Generation in the Minimum Error Discrimination Strategy
(MDPI, 2019)We study the classical and quantum correlations in the minimum error discrimination (ME) of two non-orthogonal pure quantum states. In particular, we consider quantum discord, thermal discord and entropy generation. We ... -
