Narrow-ridge interband cascade lasers were subjected to accelerated aging. The aging curves were statistically evaluated by a log-normal distribution of the failure time, and by the mixed effects of the degradation parameters. Based on 10,000 h of output power trend data for lasers operating at 90°C and the maximum cw power, an unexpectedly long lifetime is(More)
Homeostasis as an ability to maintain structural-functional parameters of the system at the required level is a basic characteristic for providing the stability of any biological system (from biosphere and separate ecosystems to communities, populations, and individuals). The study of homeostatic mechanisms that provide the stability of biological systems(More)
The LHCb experiment stores around 10 collision events per year. A typical physics analysis deals with a final sample of up to 10 events. Event preselection algorithms (lines) are used for data reduction. Since the data are stored in a format that requires sequential access, the lines are grouped into several output file streams, in order to increase the(More)
The population phenetic structure was studied in the burying beetle Nicroforus vespillo (Linnaeus, 1761) from Kaluga city pine forest. Some possible phenes of N. vespillo were distinguished and frequencies of their occurrence studied. As a result, all the samples belonged to the same population. The phene pool of the population was characterized by indices(More)
We demonstrate a quantum cascade laser for detecting <sup>12</sup>CO<inf>2</inf> and <sup>12</sup>CO<inf>2</inf> isotopes for use in fingerprinting CO<inf>2</inf> emissions from sources such as power plants and carbon storage reservoirs. The lasers emit a single mode at 4.22 &#x03BC;m in continuous wave operation.
A population-phenogenetic analysis of plants (European white birch) based on investigation of the stability of their development in natural populations was performed. The data obtained allow characterizing the violation of the stability in natural populations as a response of developing organisms to environmental (climate) changes not only in the(More)
The dynamics of developmental stability of two burying beetle species displays the trend of an increase in fluctuating asymmetry indices at almost all of the studied sites. It is assumed that the most likely cause of the observed alterations is the deviations from optimal conditions, which result mainly from global climate change.
