Regulation of Liquid Self‐Transport Through Architectural‐Thermal Coupling: Transitioning From Free Surfaces to Open Channels

open access: yesAdvanced Science, EarlyView.
Inspired by the skin of the Texas horned lizard, hierarchical structures composed of primary wedged grooves and secondary capillary crura are proposed, and the regulation of liquid self‐transport is achieved through architectural and thermal coupling, transitioning from free surfaces to open channels.

Measures of tonic and phasic activity of the locus coeruleus—norepinephrine system in children with autism spectrum disorder: An event‐related potential and pupillometry study

open access: yesAutism Research, Volume 15, Issue 12, Page 2250-2264, December 2022., 2022
Abstract A growing body of research suggests that locus coeruleus‐norepinephrine (LC‐NE) system may function differently in individuals with autism spectrum disorder (ASD). Understanding the dynamics of both tonic (resting pupil diameter) and phasic (pupil dilation response [PDR] and event‐related potential [ERP]) indices may provide meaningful ...

A Molecular Theory of the Onset of Turbulence

open access: yesScience Diliman, 1999
We review experimental data which shows the dependence of the critical Reynolds number on molecular composition. We then use the cell model of a gas to explain the onset of turbulence by the excitation of the internal degrees of freedom of molecules. Two

KLF1 Promotes Cardiomyocyte Proliferation and Heart Regeneration Through Regulation of Wnt/β‐Catenin Signaling Pathway

open access: yesAdvanced Science, EarlyView.
In KLF1‐on (neonatal and Klf1 overexpression hearts) models, KLF1 regulates Wnt/β‐catenin signaling pathway and the expression of cell proliferation‐related genes via transcriptional and epigenetic mechanisms, which induces cardiomyocyte proliferation and cardiac regeneration in mice after myocardial infarction.

A Hollow Shell‐Lattice Soft Robot in Flexible Pipelines with Flowing Fluids

open access: yesAdvanced Science, EarlyView.
This study proposes a novel shell‐lattice robot with hollow bodies, capable of crawling through pipes with flowing fluids of high velocities and viscosities and mixed with impurities. The robot also features capabilities of crawling with high payloads, in curved pipes, and unthethered crawling. These unique properties make this robot high promising for

Prandtl number effect on near wall temperature profile in high-Reynolds number channel flows

open access: yesNihon Kikai Gakkai ronbunshu, 2014
Prandtl number (Pr) effects on characteristics of the thermal boundary layer were investigated by means of Direct Numerical Simulations (DNS) in high-Reynolds number turbulent channel flows. The molecular Pr conditions were changed from 0.71 to 25.0, and
