Classification of bad pixels of the Hawaii-2RG detector of the ASTROnomical NearInfraRed CAMera

ASTRONIRCAM is an infrared camera-spectrograph installed at the 2.5-meter telescope of the CMO SAI. The instrument is equipped with the HAWAII-2RG array. A bad pixels classification of the ASTRONIRCAM detector is proposed. The classification is based on histograms of the difference of consecutive non-destructive readouts of a flat field. Bad pixels are classified into 5 groups: hot (saturated on the first readout), warm (the signal accumulation rate is above the mean value by more than 5 standard deviations), cold (the rate is under the mean value by more than 5 standard deviations), dead (no signal accumulation), and inverse (having a negative signal accumulation in the first readouts). Normal pixels of the ASTRONIRCAM detector account for 99.6% of the total. We investigated the dependence between the amount of bad pixels and the number of cooldown cycles of the instrument. While hot pixels remain the same, the bad pixels of other types may migrate between groups. The number of pixels in each group stays roughly constant. We found that the mean and variance of the bad pixels amount in each group and the transitions between groups do not differ noticeably between normal or slow cooldowns.Comment: 11 pages, 7 Figures, 3 table

Arctic polar vortex dynamics during winters 2014/2015 and 2020/2021

The dynamic barrier of the polar vortex contributes to lowering the temperature inside the vortex in the lower stratosphere and prevents the penetration of air masses into the vortex. The presence of a dynamic barrier during winter is one of the criteria determining the possibility of ozone depletion from late winter to spring. We considered the dynamics of the Arctic polar vortex in the winters of 2014/2015 and 2020/2021 at the 50, 30 and 10 hPa levels by the vortex delineation method using the geopotential. In early January 2015 and 2021, sudden stratospheric warmings were recorded as a result of the splitting (4 January 2015) and the significant displacement (5 January 2021) of the polar vortex. In both cases, the weakening of the dynamic barrier of the polar vortex was observed. The polar vortex is characterized by the presence of a dynamic barrier, when the wind speed along the entire edge of the vortex is more than 20, 24 and 30 m/s at the 50, 30 and 10 hPa levels, respectively. A decrease in the average wind speed along the vortex edge below 30, 36 and 45 m/s, at the 50, 30 and 10 hPa levels, respectively, usually indicates a local decrease in the wind speed below 20, 24 and 30 m/s at these levels, i.e., indirectly indicates a weakening of the dynamic barrier.The dynamic barrier of the polar vortex contributes to lowering the temperature inside the vortex in the lower stratosphere and prevents the penetration of air masses into the vortex.

INNOVATIVE POTENTIAL OF THE ORGANIZATION AS A COMPETITIVE FORCE OF «ELENA FURS» FACTORY

The purpose of the article consists in the choice of the approach to the assessment of the innovative potential of the organization, since the quality of the assessment of innovation potential becomes the basis of the strategy of innovation transformation. Each approach is tested on the example of the fur factory «Elena Furs» and the feasibility and validity of the assessment of the innovative potential of the organization is checked. The article contains calculations confirming the availability of innovative capacity in the organization, but the use of these approaches did not allow us to identify specific areas for its development. The estimation of innovative potential from positions of competitive force in the external environment is offered that will allow to compare innovative potential with potential of participants of an environment and to develop strategic directions of development of innovative potential in the field of new technologies of production, marketing, personnel management, etc

Buy-out of pets because of their unproper treatment under civil legislation of Russia and post-soviet countries

The article deals with one of the compulsory methods of ownership right termination - the buy-out of pets if they are treated improperly. The authors draw attention to the specifics of this reason, which is associated with the buy-out subject, i.e. with an animal. They performed the comparative analysis of "pet improper treatment" and "cruel animal treatment" concepts, the problem of their differentiation is studie

PROBLEM OF INNOVATIVE DEVELOPMENT OF MODERN PROFESSIONAL EDUCATION IN RUSSIA

В статье рассматриваются особенности развития современного профессионального образования как мощного фактора экономического роста, духовно-нравственного возрождения нации. Определяющим в системе глубины и качества такого развития должно стать инновационное образование как новая педагогика, новые образовательные технологии, ориентированные на развитие творчества конкретных субъектов образовательного взаимодействия.

Semantic similarity and analysis of the word frequency dynamics

© Published under licence by IOP Publishing Ltd. In this study a similarity in changes of frequencies dynamics for semantically related words was analyzed using word statistics extracted from more than 4.5 million books written over a period of 205 years. The approach is based on the correlation analysis of 1-grams frequency dynamics. We analyzed the frequencies correlation of synonym pairs, their corresponding antonymous groups and random words pairs. Also, we compared several metrics to find the most effective for assessing the degree of similarity in the dynamics of use of different words. Comparing differences between logarithmic rank variations in pairs of synonyms and random word pairs, significant differences are found, though they are smaller than it could be expected
