Self-stresses control stiffness and stability in overconstrained disordered networks [PDF]
Phys. Rev. E 99, 023001 (2019), 2018 We investigate the interplay between pre-stress and mechanical properties in random elastic networks. To do this in a controlled fashion, we introduce an algorithm for creating random freestanding frames that support exactly one state of self stress. By multiplying all the bond tensions in this state of self stress by the same number---which with the ...

First contact breaking distributions in strained disordered crystals [PDF]
, 2022 We derive exact probability distributions for the strain ($\epsilon$) at which the first stress drop event occurs in uniformly strained disordered crystals, with quenched disorder introduced through polydispersity in particle sizes. We characterize these first stress drop events numerically as well as theoretically, and identify them with the first ...

The impact of the military mission in Afghanistan on mental health in the Canadian Armed Forces: a summary of research findings [PDF]
European Journal of Psychotraumatology, 2014 Background: As Canada's mission in Afghanistan winds down, the Canadian Forces (CF) are reflecting on the psychological impact of the mission on more than 40,000 deployed personnel.

Note: Simple argument for emergent anisotropic stress correlations in disordered solids [PDF]
, 2020 It is now well-established that mechanical equilibrium in athermal disordered solids gives rise to anisotropic spatial correlations of the coarse-grained stress field that decay in space as $1/r^d$, where $r$ is the distance from the origin, and $d$ denotes the spatial dimension. In this note we present a simple, geometry based argument for the scaling

Serotonin and corticosterone rhythms in mice exposed to cigarette smoke and in patients with COPD:implication for COPD-associated neuropathogenesis [PDF]
, 2014 The circadian timing system controls daily rhythms of physiology and behavior, and disruption of clock function can trigger stressful life events. Daily exposure to cigarette smoke (CS) can lead to alteration in diverse biological and physiological ...

History effects in the creep of a disordered brittle material [PDF]
arXiv, 2022 We study the creep behavior of a disordered brittle material (concrete) under successive loading steps, using acoustic emission and ultrasonic sensing to track internal damage. The primary creep rate is observed to follow a (Omori-type) power-law decay in the strain rate, the number of acoustic emission events as well as the amplitudes of the ...

Models of plastic depinning of driven disordered systems [PDF]
Pramana 64, 1097 (2005), 2005 Two classes of models of driven disordered systems that exhibit history-dependent dynamics are discussed. The first class incorporates local inertia in the dynamics via nonmonotonic stress transfer between adjacent degrees of freedom. The second class allows for proliferation of topological defects due to the interplay of strong disorder and drive.
