Transient spatiotemporal chaos in the complex Ginzburg-Landau equation on long domains [PDF]

, 2010
Numerical simulations of the complex Ginzburg-Landau equation in one spatial dimension on periodic domains with sufficiently large spatial period reveal persistent chaotic dynamics in large parts of parameter space that extend into the Benjamin-Feir ...

The rise and fall of the Television Broadcasters Association, 1943–1951 [PDF]

, 2016
Although television manufacturing in the United States stalled during World War II, the television industry did not simply disappear from 1941 to 1945. Its interrelated components continued to plan, debate, and formulate. That planning drove demand for a

Analysis of Spectrum Occupancy Using Machine Learning Algorithms [PDF]

, 2015
In this paper, we analyze the spectrum occupancy using different machine learning techniques. Both supervised techniques (naive Bayesian classifier (NBC), decision trees (DT), support vector machine (SVM), linear regression (LR)) and unsupervised ...

Superconductivity near lattice instability: the case of NbC$_{1-x}$N$_x$ and NbN

, 2011
Using density functional theory within the local density approximation we report a study of the electron-phonon coupling in NbC$_{1-x}$N$_x$ and NbN crystals in the rocksalt structure. The Fermi surface of these systems exhibits important nesting.

Ab initio calculations of the physical properties of transition metal carbides and nitrides and possible routes to high-Tc

, 2006
Ab initio linear-response calculations are reported of the phonon spectra and the electron-phonon interaction for several transition metal carbides and nitrides in a NaCl-type structure.

Scalar self-energy for a charged particle in global monopole spacetime with a spherical boundary

, 2012
We analyze combined effects of the geometry produced by global monopole and a concentric spherical boundary on the self-energy of a point-like scalar charged test particle at rest. We assume that the boundary is outside the monopole's core with a general
