I argue that conventional estimates of the criterion for classical behavior of a macroscopic body are incorrect, because they do not take into account the locality of interactions, which characterizes the behavior of all systems described approximately by local quantum field theory. Black holes are the only localized objects which do not have such a description. The deviations from classical be...

Caenorhabditis elegans locomotion is a stereotyped behavior that is ideal for genetic analysis. We integrated video microscopy, image analysis algorithms, and fluid mechanics principles to describe the C. elegans swim gait. Quantification of body shapes and external hydrodynamics and model-based estimates of biomechanics reveal that mutants affecting similar biological processes exhibit related...

In the current paper the results of a numerical simulation that were verified by a well instrumented experimental procedure for studying the arching effect over a trapdoor in sand is presented. To simulate this phenomenon with continuum mechanics, the experimental procedure is modeled in ABAQUS code using stress dependent hardening in elastic state and plastic strain dependent frictional harden...

backgrounds: the prevalence of disordered eating behaviors has been reported to increase in recent decades; therefore, scientific studies should perform for specifying psychological variables that may contribute to the etiology of this disorder. in this study, we examined the role of body image disturbance and perfectionism variables in predicting disordered eating behaviors among female studen...

background: breast and testicular cancers affect a substantial and increasing proportion of the global population. self-examination encourages early detection and treatment of these cancers, which positively impacts on patient quality of life and survival. methods: the present study investigated the role of body esteem in breast and testicular self-examination. men ( n = 60) and women ( n = 90)...
