It is now well understood that equations of viscoelasticity can be seen as perturbation of wave type equations. This observation can be exploited in several different ways and it turns out that it is a usefull tool when studying controllability. Here we compare a viscoelastic system which fills a surface of a solid region (the string case has already been studied) with its memoryless counterpar...

We present a general and exact formalism for finding the evolution of a quantum system subject to external telegraph noise. The various qubit decoherence rates are determined by the eigenvalues of a transfer matrix. The formalism can be applied to a qubit subject to an arbitrary combination of dephasing and relaxational telegraph noise, in contrast to existing non-perturbative methods that trea...

We show a device with which, apparently, information (in the form of a ”slash-dot” code) is instantly transmitted via Bell state collapse, over arbitrary distance. We discuss some problems and paradoxes arising when this conclusion is viewed in the relativistic framework.

A contemporary of such important figures as Laplace, Coulomb, Herschel, Jefferson, Kant and Betancourt, the Spaniard Francisco Salva y Campillo (17511828) was a prominent late Enlightenment scientist who dedicated his whole life to researching on different topics related to diverse fields of knowledge by applying scientific method. Five years before Samuel Thomas von Sómmering (17551830) demons...

in this work, the solution of a boundary value problem is discussed via asemi analytical method. the purpose of the present paper is to inspect theapplication of the adomian decomposition method for solving the nagumo tele-graph equation. the numerical solution is obtained for some special cases sothat demonstrate the validity of method.
