Vanishing efficiency of speeded-up quantum Otto engines
(IOP, 2019-08-28)We assess the energy cost of shortcuts to adiabatic expansions or compressions of a harmonic oscillator, the power strokes of a quantum Otto engine. Difficulties to identify the cost stem from the interplay between different ... -
Vargar
(Mythopoeic Society, 2021)Squinting my eyes and resuming the frenzied spurring, I headed unflinchingly towards the setting sun. The gap between my steed and the couple of pursuers was widening, we were almost outside their shooting range. -
Variability and distribution of parasites, pathologies and their effect on wild mussels (Mytilus sp) in different environments along a wide latitudinal span in the Northern Atlantic and Arctic Oceans
(Elsevier, 2022-04)[EN] Histopathological examination in mussels can provide useful information for the diagnosis of ecosystem health status. The distribution of parasites in mussels can be conditioned by several environmental factors, ... -
Variability in cerebrospinal fluid microRNAs through life
(Springer, 2020-07-16)The development of human brain starts in the first weeks of embryo differentiation. However, there are many relevant neurodevelopmental processes that take place after birth and during lifespan. Such a fine and changing ... -
Variability in the air-sea interaction patterns and timescales within the south-eastern Bay of Biscay, as observed by HF radar data
(Copernicus Gesellschaft MBH, 2013)Two high-frequency (HF) radar stations were installed on the coast of the south-eastern Bay of Biscay in 2009, providing high spatial and temporal resolution and large spatial coverage of currents in the area for the first ... -
Variability in the Beneficial Effects of Phenolic Compounds: A Review
(MDPI, 2022-05-04)When analysing the beneficial effects of phenolic compounds, several factors that exert a clear influence should be taken into account. The content of phenolic compounds in foods is highly variable, directly affecting ... -
Variability of indication criteria in knee and hip replacement: an observational study
(BioMed Central, 2010)Background Total knee (TKR) and hip (THR) replacement (arthroplasty) are effective surgical procedures that relieve pain, improve patients' quality of life and increase functional capacity. Studies on variations in medical ... -
Variability of the Motor Behavior during Continued Practice of the Same Motor Game: A Preliminary Study
(MDPI, 2020-11-22)Motor behavior assessment during games could help physical education teachers and team coaches to design effective and efficient motor interventions. This study aimed to assess the variability of the physical and behavioral ... -
Variable Capacity for Acute and Chronic Thermal Compensation of Physiological Rates Contributes to Inter-Individual Differences in Growth Rate in Mussels (Mytilus galloprovincialis)
(Frontiers Media, 2020-09)The aim of this study was to ascertain if the capacity for acute and chronic compensation of thermal effects on physiological rates represents a trait contributing to inter-individual growth rate differences in the mussel ... -
Variable phenotype in HNF1B mutations: extrarenal manifestations distinguish affected individuals from the population with congenital anomalies of the kidney and urinary tract
(Oxford Academic, 2019)Background: Mutations in hepatocyte nuclear factor 1B (HNF1B) have been associated with congenital anomalies of the kidney and urinary tract (CAKUT) in humans. Diabetes and other less frequent anomalies have also been ... -
Variable selection with LASSO regression for complex survey data
(Wiley, 2023-12)Variable selection is an important step to end up with good prediction models. LASSO regression models are one of the most commonly used methods for this purpose, for which cross-validation is the most widely applied ... -
Variable Speed Control In Wells Turbine-Based Oscillating Water Column Devices: Optimum Rotational Speed
(IOP Publishing LTD, 2018)The effects of climate change and global warming reveal the need to find alternative sources of clean energy. In this sense, wave energy power plants, and in particular Oscillating Water Column (OWC) devices, offer a huge ... -
Variable speed wind turbine control scheme using a robust wind torque estimation
(Elsevier, 2018-10-04)This work proposes a robust controller for a variable speed wind turbine system with a doubly feed induction generator. The controller aims at tracking the optimal speed of the wind turbine so that extracts the maximum ... -
Variable Speed Wind Turbine Controller Adaptation By Reinforcement Learning
(ACM, 2016-12-30)The control of Variable Speed Wind Turbines (VSWT) to achieve optimal balance of power generation stability and rotor angular speed is impeded by the non-linear dynamics of the turbine-wind interaction and sudden changes ... -
Variable structure control for maximum wind power extraction
(ACTA Press, 2009)The actual wind turbines are provided with adjustable speed generators.Iike the double feed induction generator, that are capable to work in variable speed operations. One of the main advantage of adjustable speed generators ... -
Variables antropométricas, hábitos y dietas alimentarias en adolescentes y jóvenes: diferencias en función del sexo
(UNED, 2016-06)El estudio tuvo como objetivo analizar las diferencias entre sexos en variables antropométricas (reales, percibidas y deseadas), en hábitos alimentarios, y en el uso de dietas alimentarias. Los participantes fueron 1.075 ... -
