High-Voltage Stations for Electric Vehicle Fast-Charging: Trends, Standards, Charging Modes and Comparison of Unity Power-Factor Rectifiers
(IEEE, 2021-06-30)Emission of greenhouse gases and scarcity of fossil fuels have put the focus of the scientific community, industry and society on the electric vehicle (EV). In order to reduce CO2 emissions, cutting-edge policies and ... -
Higher Order Non-Planar Electrostatic Solitary Potential in a Streaming Electron-Ion Magnetoplasma: Phase Plane Analysis
(MDPI, 2023-02-06)We investigate cylindrical and spherical solitons in electron-ion (EI) plasma that contains hot (cold) electrons with stationary ions. The magneto-hydrodynamic equations are solved with the aid of the reductive perturbation ... -
Higher Order Sliding Mode Control of MIMO Induction Motors: A New Adaptive Approach
(MDPI, 2023-11-06)In this paper the objective is to force the outputs of nonlinear nonaffine multi-input multi-output (MIMO) systems to track those of a linear system with the desired properties. The approach is based on designing higher ... -
Higher order vortex gyrotropic modes in circular ferromagnetic nanodots
(Nature Publishing Group, 2014-04-25)Magnetic vortex that consists of an in-plane curling magnetization configuration and a needle-like core region with out-of-plane magnetization is known to be the ground state of geometrically confined submicron soft magnetic ... -
Higher versus lower nut consumption and changes in cognitive performance over two years in a population at risk of cognitive decline: a cohort study
(Elsevier, 2023-08)Background Tree nuts and peanuts (henceforth, nuts) are nutrient-dense foods rich in neuroprotective components; thus, their consumption could benefit cognitive health. However, evidence to date is limited and inconsistent ... -
Higher-Order Electrocyclizations in Biological and Synthetic Processes
(Wiley, 2023-11)In general, electrocyclizations follow the Woodward-Hoffmann's rules of conservation of orbital symmetry. These rules have been extensively verified in low-order processes, both in thermal and photochemical reactions, up ... -
Higher-Order Topological Insulators
(American Association for the Advancement of Science, 2018-06)Three-dimensional topological (crystalline) insulators are materials with an insulating bulk but conducting surface states that are topologically protected by time-reversal (or spatial) symmetries. We extend the notion of ... -
Highlighting the Compound Risk of COVID-19 and Environmental Pollutants Using Geospatial Technology
(Nature, 2021-04-16)The new COVID-19 coronavirus disease has emerged as a global threat and not just to human health but also the global economy. Due to the pandemic, most countries affected have therefore imposed periods of full or partial ... -
Highlighting the lack of neuropsychologists and speech therapists in healthcare services towards an accurate (pre‐ and postoperative) cognitive assessment in low‐grade glioma patients
(WILEY, 2022)Key points Due to the slow growth of Low‐grade gliomas (LGGs), cognitive impairments can be quite difficult to detect at early stages There is a lack of staff specialized on the cognitive and emotional assessment of ... -
Highlights of the 2nd International Symposium on Tribbles and Diseases: Tribbles Tremble in Therapeutics for Immunity, Metabolism, Fundamental Cell Biology and Cancer
(Institute of Materia Medica, 2019-03)The Tribbles (TRIB) family of pseudokinase proteins has been shown to play key roles in cell cycle, metabolic diseases, chronic inflammatory disease, and cancer development. A better understanding of the mechanisms of TRIB ... -
Highly Diastereoselective Multicomponent Synthesis of Spirocyclopropyl Oxindoles Enabled by Rare-Earth Metal Salts
(American Chemical Society, 2023-04)The synthesis of polysubstituted spirocyclopropyl oxindoles using a series of rare-earth metal (REM) salts is reported. REMs, in particular Sc(OTf)3, allowed access to the target compounds by a multicomponent reaction with ... -
