We propose and numerically demonstrate the generation of wideband millimeter-wave (mmW) flat chaos with controllable power spectrum by injection of chaotic signal from external cavity semiconductor laser (ECSL) into optical time lens with noise phase modulation.Simulation results indicate consistent elimination of the ECSL relaxation oscillation fr
INTRODUCTION: As part of the young age bracket, undergraduate university students are exposed to a range of risky behaviors including HIV/AIDS.Given the paucity of data among the risk behaviors of African university students, this study was conducted to examine the sexual risk behaviors of this group in Ethiopia.METHODS: A self-administered questio
This study has developed a sensitive and simple ultra-high performance liquid chromatography-electrospray ionization-tandem mass spectrometry method for the simultaneous determination of corydaline, dehydrocorydaline, tetrahydropalmatine, protopine, palmatine, tetrahydroberberine, columbamine, berberine, coptisine and berberrubine in beagle dog pla
We proposed a new type of distributed feedback laser with alternating active- and passive-cavities (APC DFB), which enjoys the same quantum well layer where the butt-joint re-growth process can be avoided.By utilizing the chirp characteristics of the APC DFB laser in a delayed self-heterodyne system, a chirped microwave signal with a sweep range up
