This work presents the absorptance of high-temperature superconducting YBa Cu O 2 3 7 d I 1 ( ) YBCO films, deposited on Si substrates, in the far infrared from 15 to 95 cm ( ) ( wav elength from 667 to 105 m m at temperatures of 100, 200, and 300 K i.e., in the ) normal state . Our experiments show a significant difference in the absorptance for radiation incident on the film side as compared ...

This paper studies the structural robustness of evolutionary models of cooperation, i.e. their sensitivity to small structural changes. To do this, we focus on the Prisoner’s Dilemma game and on the set of stochastic strategies that are conditioned on the last action of the player’s opponent. Strategies such as Tit-For-Tat (TFT) and Always-Defect (ALLD) are particular and classical cases within...

Solutions to the twisted Yang-Baxter equation arising from intertwin-ers for cyclic representations of U q (sl n) are described via two coupled the lattice current algebras.

Nanocrystalline cadmium sulfide thin films as antireflection materials for solar cells have been prepared by a new chemical solution deposition route in an aqueous medium at 50 °C. as-deposited thin films were studied using X-ray diffraction (XRD), field emission scanning electron microscopy (FE-SEM), and optical absorption spectra. X-ray diffraction data indicated the formation of hexagonal na...

This study is focused on the investigation of SnS thin film for transistor application. Electron trap which associated with grain boundary effect affects electrical conductivity semiconductor thereby militating attainment threshold voltage required operation. Grain size and a function semiconductor’s thickness. films 0.20, 0.25, 0.30, 0.35, 0.40 μm were deposited using aerosol assisted chemical...

The correlators of two-dimensional rational conformal field theories that are obtained in the TFT construction of [ I , II , IV ] are shown to be invariant under the action of the relative modular group and to obey bulk and boundary factorisation constraints. We present results both for conformal field theories defined on oriented surfaces and for theories defined on unoriented surfaces. In the...

The use of thin magnetic film memories for high speed computers has been well established. More recently, efforts have been made to adapt thin-film memory elements for operation in a phase script mode by using drive fields at two different frequencies to switch and read the state of the memory element. The resulting memory system is uniquely suited for operation in a parametron computer where i...
