Psychological stressors elicit the anticipation of homeostatic challenge, whereas physical stressors are direct threats to homeostasis. Many rodent models of stress include both types of stressors, yet deficits, like those reported for working memory, are often attributed to psychological stress. To empirically test whether intermittent psychological stressors, such as repeated threats, are solely...
The Bateman equations model the evolution of nuclide number densities as a function of time when they are subjected to irradiation. When particles such as neutrons, protons and deuterons interact with a material, several reactions can occur. Depending on the nuclides which are being irradiated, the nuclide may absorb the incoming particle, collide with the incoming particle causing scattering or it...
Here we present a novel biologically inspired tactile sensor based on the structure of the human fingertip. Unlike previous biologically inspired sensors, it is based on new theories of the functional morphology of the fingertip skin features and the Meissner's Corpuscles mechanoreceptors pervading them, particularly in the encoding of tactile edge information. Through mimicking the layered macro-structure...
