Vehicle Following Problem: A Control Approach for Uncertain Systems with Lossy Networks
(2018-09)In the present work, a control system based in Networked Control Systems is proposed, in order to provide a suitable solution to the vehicle following problem. This problem presents the two main obstacles: the first been ... -
Velocity loss thresholds reliably control kinetic and kinematic outputs during free weight resistance training
(2020-09)Exercise velocity and relative velocity loss thresholds (VLTs) are commonly used in velocity-based resistance training. This study aims to quantify the between-day reliability of 10%, 20%, and 30% VLTs on kinetic and ... -

Vitamin C Is an Essential Antioxidant That Enhances Survival of Oxidatively Stressed Human Vascular Endothelial Cells in the Presence of a Vast Molar Excess of Glutathione
(2007)Cellular glutathione levels may exceed vitamin C levels by 10-fold, generating the question about the real antioxidant role that low intracellular concentrations of vitamin C can play in the presence of a vast molar excess ... -
Vitamin D supplementation for the treatment of COVID-19: a living systematic review
(2022)La vitamina D es un nutriente esencial cuya deficiencia se ha asociado con el riesgo de aparición de diversas enfermedades crónicas, como la osteoporosis, la hipertensión arterial, la enfermedad cardiovascular, la diabetes, ... -
Vitamin K for upper gastrointestinal bleeding in patients with liver diseases
(2005-07-20)There is no evidence to establish the beneficial or harmful effects of vitamin K for upper gastrointestinal bleeding in patients with liver diseases Upper gastrointestinal bleeding is one of the most frequent causes of ... -
Vitamina C y Cáncer ¿amigos o enemigos?
(2020-07)La vitamina C es el antioxidante más conocido, debido a su asociación con la prevención del resfrío común. Esta vitamina también participa en la síntesis de colágeno y de catecolaminas, actuando como cofactor de hidrolasas. ... -
Voltage Balancing of a Modular Neutral-Point-Clamped Converter With a Carrier-Based Modulation Scheme
(2018-10)The five-level modular neutral-point-clamped (5L-MNPC) converter is realized by connecting two three-level neutral-point-clamped modules in series. For five-level operation, each dc-bus capacitor voltage of the modular ... -
Water-Soluble Polymers and Their Polymer-MetalIon-Complexes as Antibacterial Agents
(2010)Natural and synthetic polymers with heteroatom, such as oxygen,nitrogen, sulfur or phosphorous, potentially can efficiently remove metal ions fromaqueous solutions. The ability of synthetic polym ers derived from imino ... -
Watersheds are not static: Implications of climate variability and hydrologic dynamics in modeling
(2013)Demands on the world’s freshwater continue to grow as the global population increases, demanding more efficiency in water resources planning and management. Therefore, better confidence and accurate hydrological predictions ... -
Weak efficiency in multiobjective equasicon vex optimization on the real-line without derivatives
(2009)This paper deals with the problem of existence of weakly efficient solution to quasiconvex vector optimization problems in a finite dimensional setting on the real-line. This consideration is motivated by algorithmic ... -
