AI Article Synopsis

  • A comprehensive continuum model for soft magnetic elastomers (SMEs) is introduced, focusing on their behavior under finite strain.
  • A numerical algorithm is detailed, which helps predict the shape changes in SME materials when exposed to a magnetic field.
  • The effectiveness of the method is showcased through various examples, highlighting the unique magnetostriction effects in different SME geometries.

Article Abstract

A consistent continuum model of a soft magnetic elastomer (SME) is presented and developed for the case of finite strain. The numeric algorithm enabling one to find the field-induced shape changes of an SME body is described. The reliability of the method is illustrated by several examples revealing specifics of the magnetostriction effect in SME samples of various geometries.

This research aimed to estimate the direct costs and analyze the epidemiological aspects of ambulatory care-sensitive conditions (ACSC) in children under one year of age, São Paulo municipality, 2011-2022. Total and average costs were calculated according to ACSC diagnosis groups by components (early neonatal, late neonatal, and post-neonatal). The trend in ACSC rates was analyzed using Prais-Winsten generalized linear regression.

This article aims to identify the relationship between material deprivation and mortality from breast, cervical, and prostate neoplasms in the Brazilian adult population and the relationship between ethnicity/skin color and material deprivation. This cross-sectional ecological study calculated the mean mortality rate per 100,000 inhabitants, and deaths were standardized by age and gender and redistributed per to ill-defined causes, stratified by age group and ethnicity/skin color. We applied the Negative Binomial model, containing the interaction between ethnicity/skin color and the Brazilian Deprivation Index (IBP).
