Elastic properties of isotropic discrete systems with skew contact normals [PDF]
, 2019 The macroscopic elastic properties of discrete assemblies are fundamental characteristics of such systems. The contribution uses homogenization procedure based on equivalence of virtual work between the isotropic elastic continuum and the discrete system

Modeling of negative Poisson’s ratio (auxetic) crystalline cellulose Iβ [PDF]
, 2016 Energy minimizations for unstretched and stretched cellulose models using an all-atom empirical force field (Molecular Mechanics) have been performed to investigate the mechanism for auxetic (negative Poisson’s ratio) response in crystalline cellulose Iβ

Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Objective In multiple sclerosis, the optimal time for deploying a therapeutic intervention is before the central nervous system is damaged; given the success of trials treating the earliest stage of MS, the radiologically isolated syndrome, developing primary prevention strategies is an important next challenge.

Effect of Confining Pressure, Relative Density and Shear Strain on the Poisson’s Ratio of Clean Sand [PDF]
, 2015 In comparison to other dynamic properties of soil, Poisson’s ratio is mostly considered as an elasti c constant. The effect of different para meters on the Poisson’s ratio of soil is neglected in most of the ...

Auxetic two-dimensional lattice with Poisson's Ratio arbitrarily close to -1
, 2014 In this paper we propose a new lattice structure having macroscopic Poisson's ratio arbitrarily close to the stability limit -1. We tested experimentally the effective Poisson's ratio of the micro-structured medium; the uniaxial test has been performed ...

High Healthcare Utilization Preceding Diagnosis with Juvenile Idiopathic Arthritis
Arthritis Care &Research, Accepted Article.Objective Though early diagnosis improves long‐term outcomes, Juvenile Idiopathic Arthritis (JIA) patients often experience prolonged, circuitous paths to diagnosis. To inform diagnostic improvement, we sought to characterize healthcare utilization in the year preceding diagnosis.

Jixie qiangdu, 2022 In view of the large difference between the elastic modulus of human bone structure and metal materials and the difficulty of control, the goal is to reduce or eliminate the “stress shielding” effect in a wide span, introduce a negative Poisson’s ratio ...
