Rigorous Justification of the Uniaxial Limit from Qian--Sheng Inertial $Q$-Tensor Theory to Ericksen--Leslie
Amphiphilic polymers in aqueous solutions can self-assemble to form bilayer membranes, and their elastic properties be captured using the well-known Helfrich model involving several constants.
The nature of pH in a pure water pool that is too small to have continuous population ions formed by dissociation not settled. Here, we use stochastic kinetics simulations the reaction pools ranging from 103 1016 waters characterize ion lifetimes and populations. An availability coefficient defined quantify intermittent presence pairs during an arbitrary observation period used proposed definition for effective nanoscopic pools. converges bulk value 7 range 1010 waters. are found increase...
Bilayer membranes self-assembled from amphiphilic molecules are ubiquitous in biological and soft matter systems. The elastic properties of bilayer essential determining the shape structure bilayers. A novel method to calculate moduli bilayers within framework self-consistent field theory is developed based on an asymptotic expansion order parameters terms curvature. In particular, used derive analytic expressions moduli, which allows us design more efficient numerical schemes. efficiency...
Liquid-crystalline orders are ubiquitous in membranes and could significantly affect the elastic properties of self-assembled bilayers. Calculating free energy bilayer with different geometries fitting them to their theoretical expressions allow us extract moduli, such as bending modulus Gaussian modulus. However, this procedure is time-consuming for liquid-crystalline In paper reports a novel method calculate moduli bilayers within self-consistent field theory framework. Based on asymptotic...
This article is concerned with the rigorous connections between inertial Qian--Sheng model and Ericksen--Leslie for liquid crystal flow, under a more general condition of coefficients. More specifically, in framework Hilbert expansions, we show that: (i) when elastic coefficients tend to zero (also called uniaxial limit), smooth solution converges that full model; (ii) coefficient simultaneously, noninertial model.
Motivated by the weighted averaging method for training neural networks, we study time-fractional gradient descent (TFGD) based on flow and explore influence of memory dependence network training. The TFGD algorithm in this paper is studied via theoretical derivations experiments. Compared with common (GD) algorithm, optimization effect significant when value fractional α close to 1, under condition appropriate learning rate η. comparison extended experiments MNIST dataset various rates.

In this paper, we consider a hydrodynamic $Q$-tensor system for nematic liquid crystal flow, which is derived from Doi-Onsager molecular theory by the Bingham closure. We first prove existence and uniqueness of local strong solution. Furthermore, taking Deborah number goes to zero using Hilbert expansion method, present rigorous derivation molecule-based Ericksen-Leslie theory.
The Doi–Onsager molecular theory is capable of providing a rather accurate description the local behavior molecules; however, its computation extremely time-consuming, since some higher-dimensional variables are typically involved. Therefore, establishing computable reduced model that can capture essential physical properties an important issue. In this work, we derived Q-tensor hydrodynamic described smectic phases with density variations from using Bingham closure approximation....
Rapid on-site detection of pesticide residues in vegetable has recently attracted much attention. Herein, a Cu-modified graphitic carbon nitride nanomaterial (Cu-C3N4) with peroxidase (POD)-like property was synthesized to construct an enzyme-based colorimetric sensing platform for the organophosphorus pesticides paraoxon (PA). Cu-C3N4 could catalyze H2O2, produced by reaction acetylcholine acetylcholinesterase and choline oxidase, which further oxidized 3,3,5,5-tetramethylbenzidine (TMB)...
The increasing reliance of drivers on navigation applications has made transportation networks more susceptible to data-manipulation attacks by malicious actors. Adversaries may exploit vulnerabilities in the data collection or processing services inject false information, and thus interfere with drivers' route selection. Such can significantly increase traffic congestions, resulting substantial waste time resources, even disrupt essential that rely road networks. To assess threat posed such...

The coupling system consists Navier–Stokes equation evolution for Q-tensor. prove global existence strong solutions three-dimensional bounded domain with homogeneous Dirichlet boundary conditions, under assumption that viscosity is sufficiently large.
In this paper, we rigorously justify the connection between Qian-Sheng's inertial $Q$-tensor model and full Ericksen-Leslie for liquid crystal flow. By using Hilbert expansion method, prove that, when elastic coefficients tend to zero(also called uniaxial limit), solution will converge system.
We consider the hydrodynamics for biaxial nematic phase characterized by a field of orthonormal frame, which can be derived from molecular-theory-based tensor model.
