Abstract In this contribution, we present a continuum mechanical transversely isotropic viscoelastic material model at finite deformations to the behavior of plant tissues peltate leaves Stephania japonica . Not many research efforts have been devoted investigate properties type leaf shape. The is obtained by postulating particular Helmholtz free energy, which split additively into an elastic a...

Abstract A two-dimensional numerical simulation is performed in the present work to study the structure of a detonation wave in high activation energy mixtures, which are characterized by their turbulent reaction zone structure and unreacted pockets. The process of transverse wave and triple point collision with the channel walls, formation and consumption mechanism of unburnt gas pockets is e...

In this work, we study the thermodynamic properties on a non--commutative background via gravitational gauge field potentials. This procedure is accomplished after contracting de Sitter (dS) group, $\mathrm{SO}(4,1)$, with Poincar\`e $\mathrm{ISO}(3,1)$. Particularly, focus static spherically symmetric black hole. manner, calculate modified Hawking temperature and other deformed thermal state q...

We construct a new mesoscopic model for granular media using Dynamical Density Functional Theory (DDFT). The includes both collision operator to incorporate inelasticity and the Helmholtz free energy functional account external potentials, interparticle interactions volume exclusion. use statistical data from event-driven microscopic simulations determine parameters not given analytically by cl...

In this study, we investigate the Pauli oscillator in a noncommutative space. other words, derive wave function and energy spectrum of spin half non-relativistic charged particle that is moving under constant magnetic field with an potential We obtain critical values deformation parameter field, which counteract normal anomalous Zeeman effects. Moreover, find has to be smaller than $2.57\times ...

The proposal for a new formulation of the Navier–Stokes equations is based on Helmholtz–Hodge decomposition where all terms corresponding to physical phenomena are written as sum divergence-free term and another curl-free term. These transformations founded bases discrete mechanics, an alternative approach mechanics continuous media, conservation acceleration segment replaces that momentum volu...

Background: Effects of electromagnetic fields on healing have been investigated for centuries. Substantial data indicates that exposure to electromagnetic field can lead to enhanced healing in both soft and hard tissues. Helmholtz coil is a device that generates pulsed electromagnetic fields. Objective: In this study, a pair of Helmholtz coils for enhancing thehealing process in periodontitis w...

The intrinsic secondary structure-forming propensities of the naturally occurring amino acids have been measured both experimentally in host-guest studies and statistically by examination of the protein structure databank. There has been significant progress in understanding the origins of intrinsic alpha-helical propensities, but a unifying theme for understanding intrinsic beta-sheet propensi...

A stochastic gradient is formulated based on deterministic gradient augmented with Cauchy simulated annealing capable to reach a global minimum with a convergence speed significantly faster when simulated annealing is used alone. In order to solve space-time variant inverse problems known as blind source separation, a novel Helmholtz free energy contrast function, H 1⁄4 E T0S; with imposed ther...

Energy Recovery Linacs (ERL) have been discussed as drivers for synchrotron radiation facilities in X-ray region for over a decade. The first proposal for a multi-turn ERL as a next generation synchrotron light facility was in 1997 [1]. Since then great advances in ERL technology and high brightness electron source development were achieved [2], ERL-based high power free electron infrared laser...
