The detrimental effect of hydrogen on metals which manifests itself as a transition from ductile to brittle failure mode is, for the first time, incorporated into unified continuum-scale predictive framework. complete Gurson model, designed predict by voiding, is extended include decohesion. Hydrogen enhanced plasticity accounted through acceleration voiding process while induced decohesion rea...

Recent data indicate that plasticity protocols have not only synapse-specific but also more widespread effects. In particular, in synaptic tagging and capture (STC), tagged synapses can capture plasticity-related proteins, synthesized in response to strong stimulation of other synapses. This leads to long-lasting modification of only weakly stimulated synapses. Here we present a biophysical mod...

Despite the apparent advantages of adaptive plasticity, it is not common. We examined the effects of variation and uncertainty on selection for plasticity using an individual-based computer simulation model. In the model, the environment consisted of a linear gradient of 50 demes with dispersal occurring either before or after selection. Individuals consisted of multiple loci whose phenotypic e...
