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 ... -
Quantum probe of an on-chip broadband interferometer for quantum microwave photonics
(IOP PUBLISHING LTD, 2018)Quantum microwave photonics aims at generating, routing, and manipulating propagating quantum microwave fields in the spirit of optical photonics. To this end, the strong nonlinearities of superconducting quantum circuits ... -
Questionnaire-Based Prevalence of Physical Activity Level on Adults According to Different International Guidelines: Impact on Surveillance and Policies
(HUMAN KINETICS PUBL INC, 2019)Background: The World Health Organization recommends 150 minutes of moderate to vigorous physical activity (PA) throughout the week. However, the weekly frequency of PA and how to combine moderate and vigorous PA to define ... -
