We calculate the wake induced in a hot, dense QCD medium by a fast parton in the framework of linear response theory. We discuss two different scenarios: (i) a weakly coupled quark gluon plasma (pQGP) described by hardthermal loop (HTL) perturbation theory and (ii) a scenario where the plasma has the properties of a quantum liquid. We show that a Mach cone can appear in the second scenario, but...

Depersonalization is a type of dissociation characterized by feelings of unreality and detachment from one’s sense of self. Despite a history rich in clinical description, depersonalization has proven difficult to define and thus measure. Not surprisingly, available measures of depersonalization have limited psychometric support. The present study examined the construct validity of three self-r...

We report the phenomenon of vibrational resonance in a single species and a two species models of groundwater-dependent plant ecosystems with a biharmonic oscillation (with two widely different frequencies ω and Ω, Ω ≫ ω) of the water table depth. In these two systems, the response amplitude of the species biomass shows multiple resonances with different mechanisms. The resonance occurs at both...

The memristor is a device whose resistance changes depending on the polarity and magnitude of a voltage applied to the device’s terminals. We design a minimalistic model of a regular network of memristors using structurally-dynamic cellular automata. Each cell gets info about states of its closest neighbours via incoming links. A link can be one ’conductive’ or ’non-conductive’ states. States o...
