In this paper we study the variational discretization and mixed finite element methods for optimal control problem governed by semilinear parabolic equations. The space discretization of the state variable is done using usual mixed finite elements. The state and the co-state are approximated by the lowest order RaviartThomas mixed finite element spaces and the control is not discreted. Then we ...
Geometric phase has been proposed as one of the promising methodologies to perform fault tolerant quantum computations. However, since decoherence plays a crucial role in such studies, understanding of mixed state geometric phase has become important. While mixed state geometric phase was first introduced mathematically by Uhlmann, recently Sjöqvist et al. [Phys. Rev. Lett. 85(14), 2845 (2000)]...
Background and Objectives: Different governance approaches have various definitions and systems about health. The purpose of this study was to compare the appropriateness of the health system performance with the ideology of the selected countries. Methods: In this comparative study, liberal countries (America, Canada, France), social countries (Russia, China, Cuba) and mixed countries (Sweden...
Spin chains have been proposed as quantum wires in many quantum-information processing architectures. Coherent transmission of quantum information in spin chains over short distances is enabled by their internal dynamics, which drives the transport of single-spin excitations in perfectly polarized chains. Given the practical challenge of preparing the chain in a pure state, we propose to use a ...
