Influence of Initial Conditions on Wind Characteristics at a Bridge Middle Span in a U-Shaped Valley by CFD and AHP

open access: yesApplied Sciences, 2022
The wind parameter distribution law at a bridge midspan in a U-shaped valley has important influence on the wind strength of this bridges. In this paper, the wind characteristics were researched by computational fluid dynamics (CFD).

Increased power gains from wake steering control using preview wind direction information [PDF]

open access: yesWind Energy Science, 2023
Yaw controllers typically rely on measurements taken at the wind turbine, resulting in a slow reaction to wind direction changes and subsequent power losses due to misalignments.

Numerical Simulation on Wind Speed Amplification of High-Rise Buildings with Openings

open access: yesAtmosphere, 2023
To explore the influence of openings on wind loads and wind speeds in high-rise buildings, the wind flow around three-dimensional (3D) square cylinders with a breadth/height aspect ratio of 1:6 was numerically simulated using the large eddy simulation ...

A Novel Integrated Algorithm for Wind Vector Retrieval from Conically Scanning Scatterometers

open access: yesRemote Sensing, 2013
Due to the lower efficiency and the larger wind direction error of traditional algorithms, a novel integrated wind retrieval algorithm is proposed for conically scanning scatterometers. The proposed algorithm has the dual advantages of less computational

A Bibliometric Analysis of Publications in Uremic Toxins From 1991 to 2024

open access: yesTherapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Background Uremic toxins are a growing area of research in nephrology, with significant implications in the progression and treatment of chronic kidney disease (CKD) and the management of end‐stage kidney disease (ESKD). This bibliometric analysis aims to evaluate the global research trends, key contributors, and the impact of publications in ...

Calpain small subunit homodimerization is robust and calcium‐independent

open access: yesFEBS Letters, EarlyView.
Calpains dimerize via penta‐EF‐hand (PEF) domains. Using single‐molecule force spectroscopy, we measured the strength and kinetics of PEF–PEF homodimer binding. The interaction is robust, shows a transient conformational step before dissociation, and remains largely insensitive to Ca2+.

Wind Field Retrieval From Co-Polarized SAR Imagery Without External Wind Direction Assistance

open access: yesIEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing
The geophysical model function for sea surface wind speed retrieval from co-polarized synthetic aperture radar (SAR) images typically requires wind direction as prior information. Obtaining wind direction relies directly or indirectly on external sources,
