The Modern World Landscape of Data Science Online Education

Data science as an emerging branch of applied knowledge and a new field of study is showing a strong momentum. Besides, the corresponding sphere of educational research is actively developing. At the same time, most of the scientific publications are aimed at studying specific issues related to the content of the programs and their methodological support. The wider context and especially the international perspective are lacking for the necessary attention of researchers.In this regard, the purpose of our study was to summarize and systematize information about training programs in the field of data science presented on online platforms of the main macro-regions – America, Europe and Asia. For this purpose, we found out what elements the corpus of data science training programs consists of, as well as how courses are distributed on educational platforms by countries, organizational providers, level of education and duration of study. Based on the data obtained, we conducted a comparative interregional study of educational programs presented on online platforms.The findings made it possible to draw conclusions about the specifics of the global landscape of data science online education, as well as to determine the specifics of the Russian segment and to formulate recommendations for solving significant problems of the domestic economy using data science online education

Synaptosome-associated protein 25 (SNAP25) synthesis in terminal buttons of mouse motor neuron

© 2015, Pleiades Publishing, Ltd. Previously, we formulated the hypothesis of compartmentalized protein synthesis in axons of motor neurons. In the axon hillock, along the entire length of the axon and in its ending, specific proteins are locally synthesized, which ensure the function of each compartment. In support of this hypothesis, in this work we studied the local protein synthesis in mouse motor nerve ending

Immunohistochemical research of reaction of motoneurons of lumbar spinal cord of the mice that were in 30-day flight on the BION-M1 biosatellite on a week readaptation to conditions of Earth gravitation

© 2016, Human Stem Cell Institute. All rights reserved.Earlier, by an immunohistochemical method we define that after 30-day space flight in motoneurons of mice lumbar spinal cord immunoexpression of the proteins responsible for synaptic transfer of a nervous impulse and proteins of heat shock proteins decrease. In this research for an assessment of animals recovery process dynamics after space flight we studied an immunoexpression of the proteins participating in synaptic transfer of a nervous impulse (synaptophisyne, and PSD95), neurotrophic factors (a vascular endothelial factor of growth - VEGF and its receptor - Flt-1) and heat shock proteins (Hsp25 and Hsp70) in motoneurons of lumbar spinal cord of a mice after 30-day space flight on the BION-M1 biosatellite and the subsequent week readaptation to conditions of Earth gravitation. In this research by immunohistochemical method determine that after a week of animals staying in the Earth gravitation conditions the immunoexpression of synaptophisyne continued to decrease while the expression of PSD95, Hsp25, Hsp70 and VEGF increased in relation to the animals removed from experiment right after 30-day flight. The obtained data confirm functional plasticity of spinal cord motoneurons in the conditions of gravitation force changing. The fact, which is especially interesting, that "switches on" of neurons protective mechanisms (strengthening of heat shock proteins and neurotrophic factor expression) happens not in response to hypogravitation influence, but only a week after return of animals to conditions of Earth gravitation

Academic and Socioсultural Adaptation of Students in Russian Universities

The article presents the results of the All-Russian sociological study of academic and sociocultural adaptation of students in Russian universities. The purpose of the article was to identify and interpret the problems of students’ adaptation to the educational process, research activities, project training, sociocultural environment of the university. The subject of the study was the selfassessment of the adaptability of junior students, as well as the factors influencing it. The novelty of the research consists in a comprehensive consideration of students’ adaptation to key activities at the university, including a new type of project activity. The empirical study was implemented through a massive online survey of students in May-July 2022. The respondents were first and second-year students enrolled in bachelor’s and full-time specialty programs in various areas of training. The total volume of the sample was 15,902 people, the maximum sampling error didn’t exceed 1%.Based on empirical data, the article shows the main problems of students’ adaptation to learning, namely, a significant amount of new information, the pace of the educational process, the format of practical classes and coursework that require more independence and activity than in school education. The authors reveal the connection between the level of students’ educational activity and initiative and the degree of their integration into the university community. The negative trend of decreasing student activity in the research field compared to the school period of study , as well as the preservation of a high proportion of those who are prone to academic fraud due to the lack of adaptive resources, is shown. It is concluded that the adaptation of students to project activities is complicated by their unwillingness to responsibility and independence, an attitude towards individualism and autonomy, an insufficiently high level of professional culture and professional knowledge, which is at odds with the expectations of project customers. At the same time, positive effects have been recorded in the field of sociocultural adaptation of nonresident and foreign students. Getting used to the specifics of Russian culture, the academic environment, and the new urban society occurs without much difficulty. The conclusion is made about the effectiveness of university programs of adaptation and support of foreign students and students with disabilities, reasoned by the absence of significant differences in adaptation problems in all groups of students

Full-genome study of gene expression in lumbar spinal cord of mice after 30-day space flight on Bion-M1 biosatellite

Experiments were conducted on male mice of the C57BL/6J for full genome study of gene expression. The animals were divided into two groups.The 'flight group' mice that had spent 30 days in space and the 'control group' mice that stayed on Earth. The spinal cord of the 'flight' group mice as extracted 14h following the biosatellite's landing. The spinal cord of the control group mice was extracted at the same time.Then the lumbar spinal cord was frozen in liquid nitrogen and kept until the beginning of the study at -80°C. Quality control of the feature was performed using the settings recommended by Agilent Technologies. Signal background was subtracted and the signal intensity of each gene was globally normalized using locally weighted scatterplot smoothing. The analysis suggests that various functional groups of genes in different types of cells in spinal cord may be involved in the development of HLS and some changes in gene expression certainly happened in motor neurons innervating affected skeletal muscles

Characterization of spinal cord glial cells in a model of hindlimb unloading in mice

© 2014 IBRO. Exposure to microgravity has been shown to result in damaging alterations to skeletal muscle, bones, and inner organs. In this study, we investigated the effects of microgravity by using a hindlimb unloading model (HUM) in mice. The characteristics of the lumbar spinal cords of HUM mice 30. days after hindlimb unloading were examined. Morphometric analysis showed reductions of the total area, gray matter, and white matter by 17%, 20%, and 12%, respectively. Myelinated fibers in the white matter showed prominent myelin destruction. Analysis of the number of glial fibrillary acidic protein (GFAP+)/S100 calcium-binding protein B (S100B-), GFAP+/S100B+, and GFAP-/S100B+ astrocytes in the ventral horn (VH), central channel area (CC), dorsal root entry zone (DREZ), main corticospinal tract (CST), and ventral funiculi (VF) showed that the number of GFAP+/S100B- astrocytes was increased in the DREZ and CST of HUM mice. Additionally, GFAP+/S100B+ cell numbers were significantly decreased in the VH and CST but did not differ in the CC or DREZ of HUM mice, as compared with the control. The numbers of GFAP-/S100B+ cells were significantly reduced only in the VH of HUM mice. Moreover, the number of ionized calcium-binding adaptor molecule 1 (Iba1+) microglia cells was significantly increased in the CC and DREZ of HUM mice. In control mice, homeobox protein HoxB8 (HoxB8+) cells were found only in the CC; in contrast, HoxB8+ cells were observed in all studied areas in HUM mice, with the greatest number found in the CC. Genome-wide transcriptome analysis of the lumbar spinal cords of HUM mice showed decreased expression of genes encoding myelin, extracellular matrix, cytoskeleton, and cell adhesion proteins. Real-time polymerase chain reaction (PCR) confirmed reductions in the expression of mpz, pmp2, pmp22, and prx genes, which are involved in myelination, as well as decreases in the levels of genes encoding extracellular matrix molecules, including glycoproteins (matrix gla protein (MGP), osteoglycin (OGN), microfibrillar associated protein 5 (MFAP), and collagen, type IV, alpha 1 (COL4A)), proteoglycans (perlecan (heparan sulfate proteoglycan) (HSPG)), and metalloproteinases (lysyl oxidase (LOX)). Thus, our results showed that hindlimb unloading caused decreases in gray and white matter areas, changes in gene expression, alterations in myelination, and phenotypic modifications in glial cells in the lumbar spinal cords of mice

The Atmospheric Chemistry Suite (ACS) of Three Spectrometers for the ExoMars 2016 Trace Gas Orbiter

The Atmospheric Chemistry Suite (ACS) package is an element of the Russian contribution to the ESA-Roscosmos ExoMars 2016 Trace Gas Orbiter (TGO) mission. ACS consists of three separate infrared spectrometers, sharing common mechanical, electrical, and thermal interfaces. This ensemble of spectrometers has been designed and developed in response to the Trace Gas Orbiter mission objectives that specifically address the requirement of high sensitivity instruments to enable the unambiguous detection of trace gases of potential geophysical or biological interest. For this reason, ACS embarks a set of instruments achieving simultaneously very high accuracy (ppt level), very high resolving power (>10,000) and large spectral coverage (0.7 to 17 μm—the visible to thermal infrared range). The near-infrared (NIR) channel is a versatile spectrometer covering the 0.7–1.6 μm spectral range with a resolving power of ∼20,000. NIR employs the combination of an echelle grating with an AOTF (Acousto-Optical Tunable Filter) as diffraction order selector. This channel will be mainly operated in solar occultation and nadir, and can also perform limb observations. The scientific goals of NIR are the measurements of water vapor, aerosols, and dayside or night side airglows. The mid-infrared (MIR) channel is a cross-dispersion echelle instrument dedicated to solar occultation measurements in the 2.2–4.4 μm range. MIR achieves a resolving power of >50,000. It has been designed to accomplish the most sensitive measurements ever of the trace gases present in the Martian atmosphere. The thermal-infrared channel (TIRVIM) is a 2-inch double pendulum Fourier-transform spectrometer encompassing the spectral range of 1.7–17 μm with apodized resolution varying from 0.2 to 1.3 cm−1. TIRVIM is primarily dedicated to profiling temperature from the surface up to ∼60 km and to monitor aerosol abundance in nadir. TIRVIM also has a limb and solar occultation capability. The technical concept of the instrument, its accommodation on the spacecraft, the optical designs as well as some of the calibrations, and the expected performances for its three channels are described

Ancient DNA suggests modern wolves trace their origin to a late Pleistocene expansion from Beringia.

Grey wolves (Canis lupus) are one of the few large terrestrial carnivores that have maintained a wide geographic distribution across the Northern Hemisphere throughout the Pleistocene and Holocene. Recent genetic studies have suggested that, despite this continuous presence, major demographic changes occurred in wolf populations between the late Pleistocene and early Holocene, and that extant wolves trace their ancestry to a single late Pleistocene population. Both the geographic origin of this ancestral population and how it became widespread remain unknown. Here, we used a spatially and temporally explicit modelling framework to analyse a dataset of 90 modern and 45 ancient mitochondrial wolf genomes from across the Northern Hemisphere, spanning the last 50,000 years. Our results suggest that contemporary wolf populations trace their ancestry to an expansion from Beringia at the end of the Last Glacial Maximum, and that this process was most likely driven by Late Pleistocene ecological fluctuations that occurred across the Northern Hemisphere. This study provides direct ancient genetic evidence that long-range migration has played an important role in the population history of a large carnivore, and provides an insight into how wolves survived the wave of megafaunal extinctions at the end of the last glaciation. Moreover, because late Pleistocene grey wolves were the likely source from which all modern dogs trace their origins, the demographic history described in this study has fundamental implications for understanding the geographical origin of the dog.L.L., K.D. and G.L. were supported by the Natural Environment Research Council, UK (grant numbers NE/K005243/1, NE/K003259/1); LL was also supported by the European Research Council grant (339941‐ADAPT); A.M. and A.E. were supported by the European Research Council Consolidator grant (grant number 647787‐LocalAdaptation); L.F. and G.L. were supported by the European Research Council grant (ERC‐2013‐StG 337574‐UNDEAD); T.G. was supported by a European Research Council Consolidator grant (681396‐Extinction Genomics) & Lundbeck Foundation grant (R52‐5062); O.T. was supported by the National Science Center, Poland (2015/19/P/NZ7/03971), with funding from EU's Horizon 2020 programme under the Marie Skłodowska‐Curie grant agreement (665778) and Synthesys Project (BETAF 3062); V.P., E.P. and P.N. were supported by the Russian Science Foundation grant (N16‐18‐10265 RNF); A.P. was supported by the Max Planck Society; M.L‐G. was supported by a Czech Science Foundation grant (GAČR15‐06446S)
