The phase diagram of the Z2 lattice Higgs model is studied without freezing out the radial excitations. Comparing the results of three meanfield models, effects of mode-mode correlations on the phase diagram are investigated. The second order end point of the first order transition line between the Higgs and the confinement phase, observed at the frozen limit of the radial mode, is shown to rea...

The problem of estimating a generic phase-shift experienced by a quantum state is addressed for a generally degenerate phase shift operator. The optimal positive operator-valued measure is derived along with the optimal input state. Two relevant examples are analyzed: i) a multi-mode phase shift operator for multipath interferometry; ii) the two mode heterodyne phase detection.

This paper presents an analytical modeling method of optimal control variables to maximize output power for switched reluctance generators (SRGs) in single pulse mode operation. This method extends the basic theory of the Stiebler model and utilizes the flux linkage function to express the inductance model of SRG. In this paper, the optimal phase current shape of SRG for maximum output power is...

—A burst-mode clock recovery circuit with a novel dual bit-rate structure is presented. It utilizes two gated-oscillators to align clock with data edges and can operate in half-rate clocking mode, doubling data throughput, as well as in full-rate clocking mode. The gated-oscillator reset-phase control scheme causes the starting phase of gated-oscillators to alternate repeatedly between 0° and 1...

Background & aim: The risks of maternal mortality and morbidity associated with cesarean delivery are three and two times higher than vaginal delivery, respectively. The majority of cesarean sections are due to failure to progress in labor. One of the common risk factors for failure to progress is small maternal body size. Cormic index is an indicator of body composition assessment, which estim...
