Guiding and Manipulating Light Fields in Microstructured Liquid Crystals

open access: yesAdvanced Physics Research, EarlyView.
This review summarizes recent advances in guided‐wave optics enabled by microstructured liquid crystal (LC) devices, covering their fundamental material properties, key degree of freedom for dynamic light field manipulations. The advances of linear guided‐wave optics, nonlinear‐optics with spatial optical solitons, and microlasers in LC‐based devices ...

Shock wave enhanced turbulent mixing in a wide-speed-range strut-based scramjet combustor

open access: yesPropulsion and Energy
The efficient mixing of fuel and oxidizer in a scramjet combustor is a critical issue for achieving future wide-speed-range flight. A numerical study is conducted using Reynolds-averaged Navier–Stokes equations coupled with shear stress transport k-ω ...

Erwin Schrödinger und die Versuchungen der (Wissenschafts‐)Biografik: Vorurteilsgefüge und Mechanismen der Skandalisierung

open access: yesBerichte zur Wissenschaftsgeschichte, EarlyView.
Since late 2021, serious allegations have been made against physicist Erwin Schrödinger, ranging from pedophilia to serial sexual abuse. These accusations have significantly tarnished the Nobel Prize winner's public reputation. The ongoing debate has repeatedly raised the question of whether, and to what extent, these grave allegations are justified ...

A Preconditioned Method for Rotating Flows at Arbitrary Mach Number

open access: yesModelling and Simulation in Engineering, 2011
An improved preconditioning is proposed for viscous flow computations in rotating and nonrotating frames at arbitrary Mach numbers. The key to the current method is the use of both free stream Mach number and rotating Mach number to construct a ...

The ageing holobiont: crosstalk between telomere dynamics, oxidative stress and the gut microbiome

open access: yesBiological Reviews, EarlyView.
ABSTRACT The gut tissue is at the frontline of early onset of ageing. It exhibits high cell turnover rates and rapid telomere shortening, which can have systemic effects on the developing or senescing organism. We conducted a literature review of studies on the crosstalk between telomere length dynamics, telomerase activity, oxidative stress, and gut ...

Compressibility effects in microchannel flows between two-parallel plates at low reynolds and mach numbers: Numerical analysis

open access: yesInternational Journal of Thermofluids
Under certain circumstances, flow in microchannels can exhibit compressibility effects even at Reynolds numbers (Re) around (below 2,300) and low Mach numbers (below 0.3).

Firm‐Size Heterogeneity in the Effects of ESG Disclosure on Firm Value Under Institutional Reform: Evidence From Japan

open access: yesBusiness Strategy and the Environment, EarlyView.
ABSTRACT Focusing on firm‐size heterogeneity, this study examines how institutional reform reshapes the effects of environmental, social, and governance (ESG) disclosure on firm value. Using 2019–2023 panel data on 1427 Japanese listed firms (before and after the 2022 Tokyo Stock Exchange reorganization and Corporate Governance Code revision), this ...

Large eddy simulation of weakly compressible turbulent flows around an airfoil

open access: yesJournal of Fluid Science and Technology, 2014
The purpose of this study is to develop a numerical method for turbulent flows at low Mach number range. To account for the weak compressibility, we modify the time marching method of the usual incompressible scheme which is based on the elliptic ...

Low Mach number limit of compressible nematic liquid crystal flows with well-prepared initial data in a 3D bounded domain

open access: yesElectronic Journal of Differential Equations, 2019
In this article, we consider the low Mach number limit of the compressible nematic liquid crystal flows in a 3D bounded domain. We establish the uniform estimates with respect to the Mach number for the strong solutions with large initial data in a ...
