Caustics of the vortex beams generated by vortex lenses and vortex axicons
Journal of the Optical Society of America A, 2020In this work, the propagation of vortex beams is treated using a catastrophe theory approach. Analytic expressions are deduced to describe caustic surfaces produced by vortex lenses and vortex axicons. The obtained analytics allow us to explain the formation of the shadow region along the optical axis for vortex beams using ...

Previously, techniques such as class hierarchy analysis and profile-guided receiver class prediction have been demonstrated to greatly improve the performance of applications written in pure object-oriented languages, but the degree to which these results are transferable to applications written in hybrid languages has been unclear.

Proceedings of the 52nd Annual Design Automation Conference, 2015
Recent advances in development of memristor devices and crossbar integration allow us to implement a low-power on-chip neuromorphic computing system (NCS) with small footprint. Training methods have been proposed to program the memristors in a crossbar by following existing training algorithms in neural network models.

Vortex configuration and vortex–vortex interaction in nano-structured superconductors
Physica C: Superconductivity, 2012Abstract We study the vortex structures and quasi-particle structures in nano-structured superconductors. We used the Bogoliubov–de Gennes equation and the finite element method and obtained stable magnetic flux structures and the quasi-particle states.

Cultural Politics
Der Mensch der Neuzeit bewegt sich fortschrittlich vorwärts und nach oben. In Zeiten der Krise jedoch gerät er ins Strudeln. Ihm wird schwindelig, er verliert sich. Der Vortex (Wirbel) versinnbildlicht solche Dynamiken der Orientierungslosigkeit, des Fortgerissenwerdens und der Entgrenzung.

Vortex Fluctuations in Vortex Liquids
1997Results of Monte Carlo (MC) simulations of a lattice London model without pinning, carried out in order to study the nature of the vortex liquid state. are reported. Evidence for vortex-line lattice melting into an entengled vortex liquid in the isotropic model are presented. Results for the model with uniaxial anisotropy are also reported.
