The textual description of Table 2 and text are incorrectly submitted and published in the original version. These discrepancies are corrected with this erratum. On page 5 (line 1): ‘‘Data from the questionnaire showed that 88 % of the participants were affected by issues relating to hearing, 75 % by touch, 50 % by vision and 38 % smell (Table 2).’’ Instead it should say: ‘‘Data from the questi...

This paper describes algorithms for threedimensional dynamic stress and fracture analysis using the material point method (MPM). By allowing dual velocity fields at background grid nodes, the method provides exact numerical implementation of explicit cracks in a predominantly meshless method. Crack contact schemes were included for automatically preventing crack surfaces from interpenetration. ...

The peridynamic model is a framework for continuum mechanics based on the idea that pairs of particles exert forces on each other across a finite distance. The equation of motion in the peridynamic model is an integro-differential equation. In this paper, a notion of a peridynamic stress tensor derived from nonlocal interactions is defined. At any point in the body, this stress tensor is obtain...

Accumulating evidence from clinical studies and pre-clinical animal models supports a role for neuropeptide Y (NPY) in adaptive emotional response following stress. The long-term impact of stress, particularly chronic stress, on availability, and function of resilience factors such as NPY may be critical to understanding the etiology of stress-related psychopathology. In these studies, we exami...

Forty-eight pigs of three known stress susceptibility classes were injected daily with porcine somatotropin (pST; 4 mg/d) or a placebo. Each pig was injected in the neck once daily until taken off test, starting when the pigs weighed 59 kg. The pST treatment was terminated at weekly intervals when individual pigs reached 109 kg, but animals continued to be fed for six additional days to allow f...

In this brief study, the stress is averaged over a two-dimensional rigid particle (disk) that is in contact with other objects via localized (point) contacts. In contrast to previous studies, the rotation dynamics of the particles is also taken into account here The stress contains four terms, (i) the static stress due to forces, (ii) the dynamic stress due to translational velocity fluctuation...

Within the context of the quantum field theory in curved space-times, Hacyan and Sarmiento defined the vacuum stress-energy tensor with respect to the accelerated observer. They calculated it for a uniform acceleration and a circular motion, and derived that the rotating observer perceives a flux. Mane related the flux to synchrotron radiation. In order to investigate the relation between the v...
