A circular patch based crossover is presented in the paper. The proposed crossover provides an isolation better than -22dB and transmission of 0dB in the band of operation. This crossover is compared with a rectangular patch based crossover operating at same frequency.

OBJECTIVES Under the prevailing conditions of imbalanced life table and historic gender discrimination in India, our study examines crossover between life expectancies at ages zero, one and five years for India and quantifies the relative share of infant and under-five mortality towards this crossover. METHODS We estimate threshold levels of infant and under-five mortality required for crosso...

During chemical reactions, molecules interact to produce new molecules. Some of the reaction mechanisms are very close to the way gene combine to produce new genes. Like the classical genetic crossover operator, chemical crossover occurs when two molecules exchange the atomic material they are composed of. Molecules do so in order to produce new and more stable molecules. Several differences ex...

We study sample-to-sample fluctuations of the gap ratio in energy spectra finite disordered spin chains. The chains are described by random-field Ising model and Heisenberg model. show that away from ergodic-nonergodic crossover, correctly captured Rosenzweig-Porter (RP) However, microscopic models significantly exceed those RP vicinity crossover. upon introducing an extension to model, one rep...

This paper discusses recent NQR/NMR studies performed on Y-Ba-Cu-0 superconductors at the University of Zürich. The work is concerned with normal state properties which are still controversial, for instance the spin-gap effect, i.e. the opening of a pseudo gap in the electron spin excitation spectrum at a temperature 7*, which lies above Tc. We will report on the detection of "anomalies" which ...

The productivity of a manufacturing system is greatly influenced by the configuration of the manufacturing system. This paper examines the importance of configuration on productivity, and the improvements that can be obtained by bufferless parallel-serial configurations, i.e. multiple machining lines in parallel, both with and without crossover between the operations. Combinatorial algebraic mo...

The recombination model is applied to the production of K, φ, Λ and Ω at all pT in central Au+Au collisions. The thermal-shower component of the recombination is found to be important for K and Λ, but not for φ and Ω in the intermediate to high pT region. The normalization and inverse slope of the thermal partons in the strange sector are determined by fitting the low-pT data. The peak in the Λ...

The case-crossover design was developed to study the effects of transient, short-term exposures on the risk of acute events, such as myocardial infarction, in the early 1990s. This paper illustrates how the principles of case-crossover design are related to the principles of crossover and case-control designs and stipulates the possibilities of case-crossover design in air pollution epidemiolog...
