We study front propagation problems for forced mean curvature flows and their phase field variants that take place in stratified media, that is, heterogeneous media whose characteristics do not vary in one direction.We consider phase change fronts in infinite cylinders whose axis coincides with the symmetry axis of the medium. Using the recently developed variational approaches, we provide a co...
One direction of research in computability theory is the study of the effective content of combinatorial theorems. The last chapter of Rosenstein’s book [2] reports on this type of investigation for linear orderings. Questions raised in that chapter have been the subject of a number of papers, and a summary of results in the area can be found in Downey [1]. In this paper, we consider the proble...
AlGaN/GaN High Electron Mobility Transistors (HEMTs) with various gate lengths have been stepstressed under both onand off-state conditions. On-state, high power stress tests were performed on 0.17 lm gate length HEMTs and a single 5 lm spaced TLM pattern. Significant degradation of the submicron HEMTs as compared to the excellent stability of the TLM patterns under the same stress conditions r...
where IX is the identity map on X . The study of the Daugavet property was inaugurated by I. Daugavet [4] in 1961; he proved that every compact operator on C([0, 1]) satisfies (1.1). Consequently, C([0, 1]) has the DP. Investigation of the Daugavet property continued in the seventies and eighties. In particular, J. Holub proved in [7] and [8] (see also [11]) that for any Hausdorff compact topol...
