Experimental Study on Liquid Flow and Heat Transfer in Rough Microchannels

Advances in Condensed Matter Physics, 2019
Although roughness is negligible for laminar flow through tubes in classic fluid mechanics, the surface roughness may play an important role in microscale fluid flow due to the large ratio of surface area to volume.

Analysis of Upper Airway Morphology Using Four‐Dimensional Dynamic MRI With Active Deep Learning‐Based Automatic Segmentation

Journal of Magnetic Resonance Imaging, EarlyView.
ABSTRACT Background Upper‐airway morphology changes during breathing can be captured with cine 4D MRI. Active‐learning nnU‐Net reduces manual labeling while maintaining accuracy. Purpose For automatic upper airway segmentation on free‐breathing cine 4D MRI using active learning and quantifying dynamic changes under two mouth positions.

Through-flow effects on Nusselt number and torque coefficient in Taylor-Couette-Poiseuille flow investigated by large eddy simulation

Journal of Thermal Science and Technology, 2016
Flow in a concentric annular passage with a rotating inner cylinder, which is called Taylor-Couette flow, is important in industrial applications, such as electric motor which requires not only effective cooling of rotating shaft but also saving power ...

Orientational instabilities in nematics with weak anchoring under combined action of steady flow and external fields

, 2005
We study the homogeneous and the spatially periodic instabilities in a nematic liquid crystal layer subjected to steady plane {\em Couette} or {\em Poiseuille} flow. The initial director orientation is perpendicular to the flow plane.

Permeative flows in cholesterics: Shear and Poiseuille flows

The Journal of Chemical Physics, 2006
By using a lattice Boltzmann scheme that solves the Beris-Edwards equations of motion describing liquid-crystal hydrodynamics, we study the response of cholesterics to shear and Poiseuille flows. The geometry we focus on is a flow along the direction of the helical axis, which is known to give rise to permeation.

A Biophysical Approach to the Design of Networks of Communication Systems

Mathematical Methods in the Applied Sciences, EarlyView.
ABSTRACT Inspired by the growth dynamics of the protist Physarum polycephalum, we employ a formalism that describes adaptive, incompressible Hagen‐Poiseuille flows on channel networks to identify graphs connecting different nodes within Euclidean space. These graphs are either suboptimal or optimal relative to their length.

Extension of the Poiseuille Formula for Shear-thickening Materials and Application to Self-compacting Concrete

Applied Rheology, 2008
In practice, while placing concrete in a formwork by pumping, the pressure generated by the pump is not controlled. In order to enhance the safety on the worksite, and in view of the current economic and ecologic arguments, it would be useful to dispose ...

Coupling CZE, Liquid‐Phase Ion Mobility, to MS/MS for Quantitative Top‐Down Proteomics: Revealing Significant Proteoform Differences Between Healthy and Alzheimer's Disease Brains

PROTEOMICS, EarlyView.
ABSTRACT Alzheimer's disease (AD) is a neurodegenerative disorder characterized by cognitive decline and pathological protein aggregation. Comprehensive quantitative proteomics of brain tissues from AD patients is critical for pursuing a better understanding of the molecular mechanisms that drive AD progression.

Plasticity in plant hydraulic traits: An evaluation of a common‐taxa experiment across a climatic gradient in the Western U.S.

PLANTS, PEOPLE, PLANET, EarlyView.
Due to climate change, plants are experiencing both prolonged drought events and increasingly variable water availability, prompting the need for better understanding of potential impacts on plant performance, as well as the identification of low‐water‐use plants.
