We examine the gain saturation effect in non-Hermitian systems of coupled gain–loss waveguides and whispering-gallery-mode microresonators, through which a continuous-variable (CV) entanglement light fields is generated. Here, we consider squeezed vacuum inputs for waveguide setup coherent drive study influence from used optical gain. Unlike ideal situation without saturation, it possible to ge...

This pilot investigation was undertaken to assess the performance of a novel fiber-optic cerebral pulse oximetry system. A fiber-optic probe designed to pass through the lumen of a cranial bolt of the type used to make intracranial pressure measurements was used to obtain optical reflectance signals directly from the brain tissue. Preliminary results from seven patients measured in the operatin...

In order to implement an integrated optical quantum circuit, designing waveguides based on the quantum box is of prime importance. To do this we have investigated optical waveguide both with and without optical pumping. The rate of absorption and emission using an array of AlGaAs/GaAs quantum box core/shell structure in the optical waveguide with various pumping intensities has computed. By con...

this experiment was conducted to evaluate the effect of vitamin premix withdrawal from diets containing different energy levels on growth performance and carcass characteristics of broilers subjected to heat stress in a completely randomized design with 2×3 factorial arrangement containing, 2 levels of energy (low and high energy) and 3 levels of vitamin premix withdrawal (28, 35 and 42 days). ...

The DARTWARS project has the goal of developing high-performing innovative traveling wave parametric amplifiers with high gain, large bandwidth, saturation power, and nearly quantum-limited noise. target frequency region for its applications is 5–10 GHz, where expected noise temperature below 600 mK. development follows two different approaches, one based on Josephson junctions kinetic inductan...

effects of partial docking on feedlot performance and body fat characteristics were studied in a fat-tailed sheep breed. thirty-eight male lambs with an average weight of 4.44 ± 0.48 were randomly divided into two groups. the lambs in one group were partially docked at 3-4 h after birth, using rubber rings, and the lambs in another group remained intact (control). after weaning, 20 male lambs f...

the aim of this study was to analyze the effect of sex, season and year of birth on growth rate of biometric measurements and body weight gain of thoroughbred foals during first six months of life. 103 thoroughbred foals (53 colts and 50 fillies) from golejewko stud born between 2006 and 2008, were used in this study. thoroughbred foals born in winter months were characterized by significantly ...
