The multi-scale nature of Wall shear stress fluctuations in turbulent Rayleigh-Benard convection [PDF]

open access: yes
Measurements of wall shear-stress fluctuations on very long timescales ($\ge$ 1900 free-fall time units) are reported for turbulent Rayleigh-Benard (RB) convection in air at the heated bottom plate of a RB cell, 2.5 m in diameter and 2.5 m in height. The

The Role of Sex Hormones in Inducing Maternal Uterine Remodeling and Vasodilation During Pregnancy [PDF]

open access: yes, 2018
Uterine vascular adaptations such as vessel growth and vasodilation are needed to facilitate the more than 10-fold increase of uteroplacental blood flow (UPBF) during pregnancy.

Mapping Nanoscale Protein‐Corona Kinetics of DoE‐Optimized Perfluorocarbon Encapsulated‐PLGA Nanoparticles by In Situ, Time‐Resolved Synchrotron SAXS

open access: yesAdvanced Healthcare Materials, EarlyView.
A two‐phase workflow (OFAT screening followed by central composite design) maps how processing variables tune PFCE‐PLGA nanoparticle size, dispersity, surface charge, loading, and 19F‐MRI signal. In situ, time‐resolved synchrotron SAXS tracks albumin‐corona growth on intact dispersions and reveals PFCE‐dependent adsorption pathways.

Experimental Study on Seismic Performance of Partially Corroded Squat RC Shear Walls in Coastal Environment

open access: yesBuildings
In coastal environments, squat reinforced concrete (RC) shear walls are susceptible to local accumulation of moisture and chloride salts, causing local corrosion in the shear walls, which in turn affects their seismic performance.

Bioengineered 3D hPSC‐Cholangiocyte Ducts With Physiological Signals for Biliary Disease Modeling

open access: yesAdvanced Healthcare Materials, EarlyView.
Tian and colleagues generated a bioengineered bile duct from human pluripotent stem cell (hPSC)‐derived intrahepatic cholangiocytes within a high‐throughput, 384‐well platform to systematically examine the influence of biliary physiological signals including fluid flow, stromal cells and bile acids, and models intrahepatic biliary disease progression ...

Numerical Simulation of Cluster-Connected Shear Wall Structures under Seismic Loading

open access: yesBuildings
The reinforced part at the bottom of high-rise assembled monolithic concrete shear wall structures generally uses cast-in-place concrete due to high elastic–plastic deformation capacity requirements, which limits the advantages of prefabricated shear ...

Heat Transfer Dynamic Analyses for Recycled-Concrete Wall Combined with Expanded Polystyrene Template

open access: yesAdvances in Materials Science and Engineering, 2018
Due to the benefits of pollution reduction, energy saving, and recycling of resources associated with the recycled concrete, together with the apparent thermal storage thermal insulation yield of expandable polystyrene (EPS) template, the heat transfer ...
