Boundary-Dependent Sleep-Wake Dysregulation in Idiopathic Hypersomnia. [PDF]

Ann Clin Transl Neurol
ABSTRACT Objective Idiopathic hypersomnia (IH) presents with excessive daytime sleepiness (EDS) despite apparently preserved nocturnal sleep, challenging traditional models of hypersomnolence based on sleep loss or fragmentation. We aimed to test the hypothesis that EDS in IH reflects excessive stabilization of the sleep state, consistent with ...

Wake Characteristics of Multiscale Buildings in a Turbulent Boundary Layer. [PDF]

Boundary Layer Meteorol
Abstract Urban forms characterised by multi-scale roughness can drastically modify the wind structure within cities affecting both pedestrian comfort and air quality at street level, however, for simplicity, most urban flow studies focus on cuboid buildings with a single length scale.

Wake-Up Stroke: Clinical and Neuroimaging Characteristics [PDF]

Cerebrovascular Diseases, 2010
<i>Background:</i> Approximately 25% of ischemic stroke patients awaken with neurological deficits. In these patients, in whom the time from symptom onset is uncertain, brain imaging is a potential strategy to characterize the ischemia duration and the presence of salvageable brain tissue.

Aerodynamics and Wake Flow Characteristics of a Four-Cylinder Cluster [PDF]

Flow, Turbulence and Combustion, 2023
AbstractThe aerodynamic behaviour and wake flow of a cluster of two-dimensional sharp-edged bluff bodies exhibits extremely complex unsteady phenomena in both near and far fields. Due to the high cost of wind-tunnel experiments and numerical simulations, a complete understanding of wake flows and a description of their characteristics are lacking. This

Electromagnetic Scattering of Near-Field Turbulent Wake Generated by Accelerated Propeller

Remote Sensing, 2021
The electromagnetic scattering study of the turbulent wake of a moving ship has important application value in target recognition and tracking. However, to date, there has been insufficient research into the electromagnetic characteristics of near-field ...

Calibration of a super-Gaussian wake model with a focus on near-wake characteristics

Journal of Physics: Conference Series, 2020
Abstract Offshore wind turbine near wakes can extend downstream up to 5D due to low atmospheric turbulence intensities. They are characterised by strong velocity deficits, a transitioning Gaussian shape, and strong added turbulence intensities. Classical analytical wake models are still used due to their low computational costs, but they

Optimal combined wake and active power control of large‐scale wind farm considering available power

IET Renewable Power Generation, 2023
The high‐order nonlinear complex characteristics of traditional static wake model (SWM) restrict the fast optimization of wake effect. Therefore, this paper introduces a dynamic wake model (DWM) to describe the time‐varying wake characteristics of wind ...
