We present schemes for the generation and evaluation of continuous variable entanglement of bright optical beams and give a brief overview of a variety of optical techniques and quantum communication applications on this basis. A new entanglement-based quantum interferometry scheme with bright beams is suggested. The performance of the presented schemes is independent of the relative interferen...
In this review an attempt has been made to analyze the results of the studies that explored the changes in the growth and development of plants exposed to continuous light published since the 1930s, including papers that are available in Russian only. Potential benefits of using a 24-h photoperiod for the production of greenhouse crops, transplant production in closed controlled environment sys...
Differential transcriptional analysis of the cyanobacterium Cyanothece sp. ATCC 51142 during light-dark and continuous-light growth.Differential transcriptional analysis of the cyanobacterium Cyanothece sp. ATCC 51142 during light-dark and continuous-light growth.
It has been shown in animal studies that exposure to brief pulses of bright light can phase shift the circadian pacemaker and that the resetting action of light is most efficient during the first minutes of light exposure. In humans, multiple consecutive days of exposure to brief bright light pulses have been shown to phase shift the circadian pacemaker. The aim of the present study was to dete...
Exposure of rats to continuous light attenuates melatonin production and results in hypertension development. This study investigated whether hypertension induced by continuous light (24 hours/day) exposure induces heart and aorta remodelling and if these alterations are prevented by melatonin or angiotensin converting enzyme inhibitor captopril. Four groups of 3-month-old male Wistar rats (10 ...
The main contribution of this paper is to present a novel method for automatic 3D face recognition based on sampling a 3D mesh structure in the presence of noise. A structured light method using line projection is employed where a 3D face is reconstructed from a single 2D shot. The process from image acquisition to recognition is described with focus on its real-time operation. Recognition resu...
