Serological Benefit of SARS‐CoV‐2 Vaccination Relative to Infection in Children With Acute Lymphoblastic Leukemia

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background Children with acute lymphoblastic leukemia (ALL) are at risk of severe outcomes from SARS‐CoV‐2 (SCV2). In the post‐pandemic context, where most children have been infected with SCV2, there are limited data on whether vaccination remains beneficial in children with ALL.

Monte-Carlo Simulations of the Dynamical Behavior of the Coulomb Glass [PDF]

, 1996
We study the dynamical behavior of disordered many-particle systems with long-range Coulomb interactions by means of damage-spreading simulations. In this type of Monte-Carlo simulations one investigates the time evolution of the damage, i.e.

Constitutive modeling of cortical bone considering anisotropic inelasticity and damage evolution

Mechanical Engineering Journal, 2017
Researchers have conducted finite element (FE) analyses with human models to predict injuries due to traffic accidents or falling. In most of their analyses, cortical bone was simply modeled as a general isotropic elastoplastic material. In this study, a

INITIAL PRODUCTION OF DEFECTS IN ALKALI-HALIDES - F AND H CENTER PRODUCTION BY NON-RADIATIVE DECAY OF SELF-TRAPPED EXCITON [PDF]

, 1977
Radiation damage in KCl can be produced by the decay of a self-trapped exciton into an F centre and an H centre. The authors present calculations of the energies of the states involved for various stages in the evolution of the damage.

Evolution law for anisotropic damage

, 1999
Summary: We give a formulation for anisotropic damage in the framework of the principle of strain equivalence. The damage variable is still related to the surface density of microcracks and microvoids, and, as its evolution is governed by the plastic strain, it is represented by a second-order tensor and is orthotropic.
