    Refractory titanium nitride two-dimensional structures with extremely narrow surface lattice resonances at telecommunication wavelengths
/ V. I. Zakomirnyi [et al.] // Appl Phys Lett. - 2017. - Vol. 111, Is. 12, DOI 10.1063/1.5000726 . - ISSN 0003-6951
Аннотация: Regular arrays of plasmonic nanoparticles have brought significant attention over the last decade due to their ability to support localized surface plasmons (LSPs) and exhibit diffractive grating behavior simultaneously. For a specific set of parameters (i.e., period, particle shape, size, and material), it is possible to generate super-narrow surface lattice resonances (SLRs) that are caused by interference of the LSP and the grating Rayleigh anomaly. In this letter, we propose plasmonic structures based on regular 2D arrays of TiN nanodisks to generate high-Q SLRs in an important telecommunication range, which is quite difficult to achieve with conventional plasmonic materials. The position of the SLR peak can be tailored within the whole telecommunication bandwidth (from ? 1.26 ?m to ? 1.62 ?m) by varying the lattice period, while the Q-factor is controlled by changing nanodisk sizes. We show that the Q-factor of SLRs can reach a value of 2 ? 103, which is the highest reported Q-factor for SLRs at telecommunication wavelengths so far. Tunability of optical properties, refractory behavior, and low-cost fabrication of TiN nanoparticles paves the way for manufacturing cheap nanostructures with extremely stable and adjustable electromagnetic response at telecommunication wavelengths for a large number of applications. © 2017 Author(s).

    Titanium nitride nanoparticles as an alternative platform for plasmonic waveguides in the visible and telecommunication wavelength ranges
/ V. I. Zakomirnyi [et al.] // Photonics Nanostruc. Fundam. Appl. - 2018. - Vol. 30. - P50-56, DOI 10.1016/j.photonics.2018.04.005 . - ISSN 1569-4410
Аннотация: We propose to utilize titanium nitride (TiN) as an alternative material for linear periodic chains (LPCs) of nanoparticles (NPs) which support surface plasmon polariton (SPP) propagation. Dispersion and transmission properties of LPCs have been examined within the framework of the dipole approximation for NPs with various shapes: spheres, prolate and oblate spheroids. It is shown that LPCs of TiN NPs support high-Q eigenmodes for an SPP attenuation that is comparable with LPCs from conventional plasmonic materials such as Au or Ag, with the advantage that the refractory properties and cheap fabrication of TiN nanostructures are more preferable in practical implementations compared to Au and Ag. We show that the SPP decay in TiN LPCs remains almost the same even at extremely high temperatures which is impossible to reach with conventional plasmonic materials. Finally, we show that the bandwidth of TiN LPCs from non-spherical particles can be tuned from the visible to the telecommunication wavelength range by switching the SPP polarization, which is an attractive feature for integrating these structures into modern photonic devices. © 2018 Elsevier B.V.

Аннотация: We studied the structuredness inA total transcriptome of Siberian larch. To do that, the contigs from total transcriptome has been labeled with the reads comprising the tissue specific transcriptomes, and the distribution of the contigs from the total transcriptome has been developed with respect to the mutual entropy of the frequencies of occurrence of reads from tissue specific transcriptomes. It was found that a number of contigs contain comparable amounts of reads from different tissues, so the chimeric transcripts to be extremely abundant. On the contrary, the transcripts with high tissue specificity do not yield a reliable clustering revealing the tissue specificity. This fact makes usage of total transcriptome for the purposes of differential expression arguable. © 2019, Springer Nature Switzerland AG.

    Reads in NGS Are Distributed over a Sequence Very Inhomogeneously
/ M. Sadovsky [et al.] // (8 May 2019 through 10 May 2019 : Springer Verlag, 2019. - Vol. 11465 LNBI. - P271-282, DOI 10.1007/978-3-030-17938-0_25 . -
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.

Аннотация: We studied the statistical properties of non-coding regions of chloroplast genomes of 391 plants. To do that, each non-coding region has been tiled with a set of overlapping fragments of the same length, and those fragments were transformed into triplet frequency dictionaries. The dictionaries were clustered in 64-dimensional Euclidean space. Five types of the distributions were identified: ball, ball with tail, ball with two tails, lens with tail, and lens with two tails. Besides, the multi-genome distribution has been studied: there are ten species performing an isolated and distant cluster; surprisingly, there is no immediate and simple relation in taxonomy composition of these clusters. © 2019, Springer Nature Switzerland AG.

Аннотация: The article contains the results of hematological, immunological and chemiluminescent analysis of the functional activity of peripheral blood cells of five-year-old lactating cows from the central regions of the Krasnoyarsk Territory (Siberia, Russia) with different radiation status, at which the radiation doses of animals were 0.02, 0.17 and 0.21 mSv per year. It was established that small doses of radiation at 0.17 mSv per year and 0.21 mSv per year affect hematological parameters, increase the phagocytic activity of blood leukocytes and change the kinetics of the formation of active oxygen forms by blood cells, which is manifested as an increase in the time of formation of the maximum kinetics of spontaneous and activated secondary radicals, reduction of the total production of secondary radicals in the antigenic activation of blood cells in vitro and an increase in the volume of spontaneously produced primary radicals. © 2019 IOP Publishing Ltd.

Аннотация: The experience of implementation of GIS and web technologies for regional agriculture of the Krasnoyarsk territory is considered. The experimental agricultural enterprise "Minino", located near the city of Krasnoyarsk, was chosen as a pilot project. For this agricultural enterprise, the comprehensive digital model using geographic information systems, remote sensing and web mapping data processing techniques and software is created. A geospatial database, which contains relevant and archival information about agricultural fields, varieties, crops, soil, particle size distribution, soil-forming rocks, terrain features, has been developed. A series of technological digital maps and cartograms have been created in which information on crop rotations and cultivated crops is concentrated. Archives of available multispectral satellite data of high spatial resolution on the considered territory are analyzed. As a result, a multi-layer electronic map of the agricultural enterprise was created, which contains all available information and can be used for modeling and forecasting crop yields, agricultural planning. The developed methods and software and technological solutions can become a methodological basis for a new generation of information and analytical systems and technologies to support management decisions in the agricultural sector. © 2019 IOP Publishing Ltd.

Аннотация: The problem of creating a geographic spatial database of morphometric indicators based on the basin approach for several rivers in the Krasnoyarsk region is considered. The division of the territory into catchment basins is carried out in a hierarchical system, up to the river tributaries of the 4-th order. The initial data for the construction of watersheds was a MERIT DEM Hydro digital relief model, vector data on the hydrographic network from A.P. Karpinsky All-Russian Research Geological Institute (VSEGEI) and Roscartography (Federal Agency of Geodesy and Cartography). In the process of data processing methods and algorithms of spatial analysis of relief and hydrological modeling, implemented in GIS software Whitebox GAT, QGIS and ArcGIS, were used. The main morphometric characteristics of the relief are calculated: slope, exposure of slopes; with the help of zone statistics for basins, the average values of these characteristics, the main statistics are calculated. We consider this work as the first stage in the creation of information support for the tasks of land use analysis, assessment of the natural resource potential of the region. © 2019 IOP Publishing Ltd.
