Machine Learning Predicting Optimal Preparation of Silica-Coated Gold Nanorods for Photothermal Tumor Ablation

Nanomaterials, 2023
Gold nanorods (GNRs) coated with silica shells are excellent photothermal agents with high surface functionality and biocompatibility. Understanding the correlation of the coating process with both structure and property of silica-coated GNRs is crucial ...

Self force on static charges in Schwarzschild spacetime [PDF]

, 1999
We study the self forces acting on static scalar and electric test charges in the spacetime of a Schwarzschild black hole. The analysis is based on a direct, local calculation of the self forces via mode decomposition, and on two independent ...

Rigorous Proof of Chaotic Behaviour in a Dumbbell Satellite Model

Journal of Mathematical Analysis and Applications, 2000
A computer assisted method is applied to rigorously prove the existence of chaotic behaviour in a differential equation modelling a dumbbell satellite moving on a Keplerian ellipse. The problem is described by a second order time periodic differential equation. The satellite is composed of two equal point masses connected by a rigid massless bar. It is

Well‐posedness for the FENE dumbbell model of polymeric flows [PDF]

Communications on Pure and Applied Mathematics, 2008
AbstractWe prove local and global well‐posedness for the FENE dumbbell model for a very general class of potentials. Indeed, in prior local or global well‐posedness results, conditions on the strength of the singularity (or on the parameter b) were made. Here we give a proof in the general case.

Graphene-Assisted Narrow Bandwidth Dual-Band Tunable Terahertz Metamaterial Absorber

Frontiers in Physics, 2020
A tunable graphene terahertz metamaterial absorber is designed by treating a monolayer continuous dumbbell-shaped structure graphene layer, which can simultaneously realize the narrow bandwidth and dual-band absorption with transverse magnetic (TM ...

NEURONAL INTEGRATIVE ANALYSIS OF THE "DUMBBELL" MODEL FOR PASSIVE NEURONS

Journal of Integrative Neuroscience, 2002
We analyze the so called "Dumbbell" model of Jackson (J. Neurophysiol. 69 (1993) pp. 464) for a single neuron consisting of a patch-clamped cell body attached to dendritic cable of finite length terminating in an oblique derivative ("natural termination") boundary condition representing a dendritic swelling or a natural ending sealed by a continuous ...

Numerical approximation of corotational dumbbell models for dilute polymers [PDF]

IMA Journal of Numerical Analysis, 2008
We construct a general family of Galerkin methods for the numerical approximation of weak solutions to a coupled microscopic-macroscopic bead-spring model that arises from the kinetic theory of dilute solutions of polymeric liquids with noninteracting polymer chains. The model consists of the unsteady incompressible Navier-Stokes equations in a bounded

A viscoelastic-viscoplastic constitutive model and its finite element implementation of amorphous polymers

Polymer Testing, 2023
The amorphous polymers present remarkable temperature- and rate-dependent deformation behaviors. Based on a combination of the multiple relaxation viscoelastic-viscoplastic model and the three-element viscoelastic model, a constitutive model was ...

Frustration of freezing in a two dimensional hard-core fluid due to particle shape anisotropy [PDF]

, 2016
The freezing mechanism suggested for a fluid composed of hard disks [Huerta et al., Phys. Rev. E, 2006, 74, 061106] is used here to probe the fluid-to-solid transition in a hard-dumbbell fluid composed of overlapping hard disks with a variable length ...

Solution of the Fokker–Planck Equation by Cross Approximation Method in the Tensor Train Format

Frontiers in Artificial Intelligence, 2021
We propose the novel numerical scheme for solution of the multidimensional Fokker–Planck equation, which is based on the Chebyshev interpolation and the spectral differentiation techniques as well as low rank tensor approximations, namely, the tensor ...
