Cerebrospinal Fluid Biomarkers of Alzheimer’s Disease: Current Evidence and Future Perspectives

open access: yesBrain Sciences, 2021
Alzheimer’s disease is a progressive, clinically heterogeneous, and particularly complex neurodegenerative disease characterized by a decline in cognition. Over the last two decades, there has been significant growth in the investigation of cerebrospinal

Retrieving the global distribution of the threshold of wind erosion from satellite data and implementing it into the Geophysical Fluid Dynamics Laboratory land–atmosphere model (GFDL AM4.0/LM4.0) [PDF]

open access: yesAtmospheric Chemistry and Physics, 2020
Dust emission is initiated when surface wind velocities exceed the threshold of wind erosion. Many dust models used constant threshold values globally.

Effect of the Coastline Geometry on the Boundary Currents Intruding through the Gap

open access: yesFluids, 2022
The problem of a geophysical western boundary current negotiating a gap in its supporting boundary is considered. For traditional straight, parallel gaps, such systems are known to exhibit two dominant states, gap penetrating and leaping, with the ...

Current and emerging deep-learning methods for the simulation of fluid dynamics

open access: yesProceedings of the Royal Society A, 2023
Over the last decade, deep learning (DL), a branch of machine learning, has experienced rapid progress. Powerful tools for tasks that have been traditionally complex to automate have been developed, such as image synthesis and natural language processing.

Current Concepts in Fluid Therapy in Horses

open access: yesFrontiers in Veterinary Science, 2021
Despite the frequent inclusion of fluid therapy in the treatment of many conditions in horses, there are limited studies available to provide evidenced-based, species-specific recommendations.

Hall Current and Soret Effects on Unsteady MHD Rotating Flow of Second-Grade Fluid through Porous Media under the Influences of Thermal Radiation and Chemical Reactions

open access: yesCatalysts, 2022
The unsteady MHD free convection heat and mass transfer flow of a viscous, incompressible, and electrically conducting fluid passing through a vertical plate embedded in a porous medium in the presence of chemical reactions and thermal radiation is ...

Effect of Time and Frequency of Magnetic Field Application on MRF Pressure Performance

open access: yesMicromachines, 2022
This research was conducted to determine the effect of the time and frequency of magnetic field application on MRF pressure performance. It was carried out by placing magnetorheological fluid (MRF) in a U-shaped, glass tube and then repeatedly applying a

On the current-voltage relationship in fluid theory [PDF]

open access: yesAnnales Geophysicae, 1999
The kinetic theory of precipitating electrons with Maxwellian source plasma yields the well-known current-voltage relationship (CV-relationship; Knight formula), which can in most cases be accurately approximated by a reduced linear formula.

STREAMING CURRENT INDUCED BY FLUID FLOW IN POROUS MEDIA [PDF]

open access: yesEarth Science Malaysia, 2018
Streaming current is induced by the relative motion between a fluid and a solid surface under a fluid pressure difference. In this work, a theoretical model for the streaming current coefficient in porous media is firstly developed based on the fractal

Control of ambient fluid on turbidity current evolution: Mechanisms, feedbacks and influencing factors

open access: yesGeosystems and Geoenvironment, 2023
Turbidity currents are important ocean dynamic processes that influence sediment transport, ocean engineering, and marine environments. As a turbidity current evolves, its macroscopic and mesoscopic properties are controlled by ambient fluid mechanisms ...
