Perturbative analysis of numerical discretization to stochastic Hamiltonian problems

, 2022
This talk will highlight recent results based on the study of numerical dynamics associated to discretization of stochastic Hamiltonian problems, since they are excellent models useful in a large number of applications, when the dynamics is subject to ...

Experience With Performing Rheocarna Therapy via the Single‐Needle Method for Treatment of Chronic Limb‐Threatening Ischemia

Therapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Introduction This study investigated the safety and efficacy of single‐needle Rheocarna therapy for chronic limb‐threatening ischemia (CLTI) with wounds. Methods Six patients with CLTI involving ulcers unresponsive to revascularization underwent single‐needle Rheocarna treatment.

HEURISTIC MODIFIED EQUATION ANALYSIS ON OSCILLATIONS IN NUMERICAL SOLUTIONS OF CONSERVATION LAWS

, 2011
Oscillations are ubiquitous in numerical solutions obtained by high order or even first order schemes for hyperbolic problems and are conventionally understood as the consequence of low dissipation effects of underlying numerical schemes.

A numerical analysis focused comparison of several Finite Volume schemes for an Unipolar Degenerated Drift-Diffusion Model

, 2020
International audienceIn this paper, we consider an unipolar degenerated drift-diffusion system where the relation between the concentration of the charged species c and the chemical potential h is h(c) = log c 1−c. We design four different finite volume

Effectiveness of a Novel Low‐Density Lipoprotein Apheresis Device Rheocarna in Patients Undergoing Hemodialysis With Chronic Limb‐Threatening Ischemia: A Single‐Center Retrospective Study

Therapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Background Chronic limb‐threatening ischemia (CLTI) is a severe form of lower‐extremity artery disease characterized by distal lesions and microcirculatory impairment, limiting revascularization efficacy. Rheocarna is a direct hemoperfusion low‐density lipoprotein (LDL) adsorption device with potential rheological and anti‐inflammatory ...

Numerical Analysis on Vehicle Collision to Flexible Precast Concrete Guard Fence [PDF]

, 2003
A new type of guard fence named Flexible Precast Concrete (FPC) guard fence has been developed in Japan. In this study, FEM models are established for truck and the FPC guard fence to simulate impact behaviors. Firstly, tension tests on the spring steel (

Numerical analysis of implicitly constituted incompressible fluids: mixed formulations

, 2020
We consider the numerical approximation of incompressible non-Newtonian flow by means of the finite element method, where the constitutive law is defined through an implicit relation G(S ,D(u)) = 0.

High-order numerical methods for scattering problems

, 2021
Scattering problems are ubiquitous in scientific and engineering applications. These problems can often be straightforwardly modeled using relatively simple linear partial differential equations, such as the Helmholtz equation.
