Аннотация: The upper-mantle structure was studied from first-arrival data along the Meteorite profile, run using underground nuclear explosions. Unlike the layered, slightly inhomogeneous models in the previous works, emphasis was laid on lateral inhomogeneity at the minimum possible number of abrupt seismic boundaries. We used forward ray tracing of the traveltimes of refracted and overcritical reflected waves. The model obtained is characterized by considerable velocity variations, from 7.7 km/s in the Baikal Rift Zone to 8.0-8.45 km/s beneath the Tunguska syneclise. A layer of increased velocity (up to 8.5-8.6 km/s), 30-80 km thick, is distinguished at the base of seismic lithosphere. The depth of the layer top varies from 120 km in the northern Siberian craton to 210 km in its southeastern framing. It has been shown that, with crustal density anomalies excluded, the reduced gravity field is consistent with the upper-mantle velocity model. В© 2013.

Аннотация: The spatial distributions of electric fields and currents in the Earth's atmosphere are calculated. Electric potential distributions typical of substorms and quiet geomagnetic conditions are specified in the ionosphere. The Earth is treated as a perfect conductor. The atmosphere is considered as a spherical layer with a given height dependence of electrical conductivity. With the chosen conductivity model and an ionospheric potential of 300 kV with respect to the Earth, the electric field near the ground is vertical and reaches 110 Vm(-1). With the 60-kV potential difference in the polar cap of the ionosphere, the electric field disturbances with a vertical component of up to 13 V m(-1) can occur in the atmosphere. These disturbances are maximal near the ground. If the horizontal scales of field nonuniformity are over 100 km, the vertical component of the electric field near the ground can be calculated with the one-dimensional model. The field and current distributions in the upper atmosphere can be obtained only from the three-dimensional model. The numerical method for solving electrical conductivity problems makes it possible to take into account conductivity inhomogeneities and the ground relief.

Аннотация: The distribution of triplets alongside a genome is studied.We explored the distribution to the nearest neighbour, that is the pattern where two triplets are fixed, and the distance is determined from the former to the latter so that the second triplet takes place nowhere inside the observed gap surrounded with the couple of the given triplets. The distribution differs strongly, for different organisms. Yeast and bacteria seem to have rather smooth pattern, while mammalia and other higher eukaryotes exhibit very complex patterns with long-range correlations in the triplet distribution. © Springer International Publishing Switzerland 2015.

Application of the technology of estimation of density, velocity, and statics corrections from gravimetric data in seismic data processing in Eastern
[Text] : статья / V. A. Kochnev [et al.] // Geomodel 2012 - 14th Scientific-Practical Conference on the Problems of Integrated Interpretation of Geological and Geophysical Data During Geological Modeling of Hydrocarbons' Deposits. - 2012
Аннотация: The use of gravity data to estimate parameters and to determine near-surface static corrections is becoming more popular. Of particular importance is the application of this method at the Siberian platform, where amplitudes of the structures are small, and the influence of strong near-surface inhomogeneities greatly distorts the wave pattern. We offer a technology of co-processing and interpretation of seismic and gravity data. The technology is based on the adaptive methods for inverse problems of gravimetry and magnetometry, implemented in packages ADG-3D and the ADM-3D, as well as existing seismic data processing packages.

Аннотация: Настоящая работа посвящена анализу температурных аномалий в городе Красноярске и его окрестностях («городские острова тепла»), которые оценивались по спутниковым данным Landsat-8 теплового инфракрасного диапазона и наземным данным с автоматизированных постов наблюдения за атмосферой. Актуальность исследования обусловлена крайне неблагоприятной экологической обстановкой в городе, сложностью оценки метеорологических характеристик территории из-за значительной неравномерности рельефа, температурным режимом разрезающей город пополам реки Енисей, который обусловлен расположенной в 40 км от города Красноярской ГЭС. Задача состояла в выявлении характерных температурных неоднородностей в городе, их пространственного местоположения и количественной оценке. Всего было рассмотрено 10 безоблачных сцен Landsat-8 на территорию Красноярска и окрестностей, в бесснежный период с 2013 по 2016 гг. Вычисления проводились на основе данных радиометра TIRS (10-й канал – ИК-диапазон 10,3–11,3 мкм). Данные каналов видимого диапазона 4-3-2 (красный-зеленый-синий), регистрируемые радиометром OLI Landsat-8, использовались для классификации изображений, определения типа подстилающей поверхности. Была выполнена обработка спутниковых данных, в том числе – классификация изображения, определение коэффициентов эмиссии для различных участков городской территории, вычисление температуры поверхности. Также был проведен сравнительный анализ полученных данных с измерениями на метеостанциях. Было обнаружено, что температура, измеренная разными способами, имеет сопоставимые значения. По результатам исследования были сформированы сезонные тепловые аномалии городской территории для трех сезонов – лета, весны и осени. Было выделено несколько сезонных тепловых аномальных зон разного типа – природные возвышенности, территории около нескольких крупных торгово-развлекательных центров, промышленные зоны ряда предприятий, участки теплового загрязнения сточными водами.
The subject of the analysis in this paper were temperature anomalies in the city of Krasnoyarsk and its surroundings («Urban Heat Islands»), which were estimated from satellite data Landsat-8 thermal infrared and ground data from automated observation posts for the atmosphere. The relevance of the study is due to the extremely unfavorable environmental situation in the city. The task was to identify characteristic temperature inhomogeneities in the city, their spatial location and quantitative assessment. In total, 10 cloudless Landsat-8 scenes were examined on the territory of Krasnoyarsk and its environs during the snowless period from 2013 to 2016. The calculations were based on the data of the TIRS radiometer (10th channel – IR range of 10.3-11.3 µm). The data of the channels of the visible range 4-3-2 (red-green-blue), registered by the OLI Landsat-8 radiometer, were used to classify the images, to determine the type of underlying surface. Satellite data processing was performed. Also, a comparative analysis of the data obtained with measurements at weather stations was carried out. It was found that the temperature measured in different ways has comparable values. According to the results of the study were formed seasonal thermal anomalies of the urban area. Several seasonal thermal anomalous zones of different types such as natural elevations, territories of about several large shopping and entertainment centers, industrial zones of a number of enterprises, sites of thermal pollution by sewage were singled out.

Аннотация: Distribution of read starts over a sequences genetic entity is studied. Key question was whether the starts are distributed uniformly and homogeneously along a sequence, or there exist some spots of the increased local density of the starts. To answer the question, 15 bacterial genomes have been studied. It was found that some genomes exhibit extremely far distribution pattern, from an homogeneity, while others show lower level of the inhomogeneity. The inhomogeneity level was determined through the Kullback-Leibler distance between the real string distribution, and that one bearing the most probable continuations of the shorter strings. © 2019, Springer Nature Switzerland AG.
