With the development of advanced molecular-genetic and computational technologies it becomes possible to tackle individual cells within a regenerating tissue, to define morphogenetic and cellular changes in space and time by live imaging, to acquire transcriptome status with single-cell RNA sequencing (ScRNA-seq), and to delineate the candidate mechanisms by iterative computational and experimental approaches. Here, we review recent findings and current knowledge on tissue regeneration in plants, focusing on four evolutionarily conserved scenarios that a cell may embark on to facilitate the regeneration of a plant tissue structure lost by injury, namely cell death, division, dedifferentiation, and transdifferentiation. Understanding of these scenarios at single-cell resolution, singularly and in combination, could provide an unprecedented view of tissue regeneration in plants.
Finite groups are said to be isospectral if they have the same sets of element orders. A finite nonabelian simple group L is said to be almost recognizable by spectrum if every finite group isospectral to L is an almost simple group with socle isomorphic to L . It is known that all finite simple sporadic, alternating and exceptional groups of Lie type, except J 2 , A 6 , A 10 and 3 D 4 (2), are almost recognizable by spectrum.

The present paper is the final step in the proof of the following conjecture due to V. D. Mazurov: there exists a positive integer d 0 such that every finite simple classical group of dimension larger than d 0 is almost recognizable by spectrum. Namely, we prove that a nonabelian composition factor of a finite group isospectral to a finite simple symplectic or orthogonal group L of dimension at least 10, is either isomorphic to L or not a group of Lie type in the same characteristic as L

and combining this result with earlier work, we deduce that Mazurov's conjecture holds with d 0 = 60.
The main mass of the Sevathur carbonatite complex (Tamil Nadu, India) consists of dolomite carbonatite with a small number of ankerite carbonatite dikes. Calcite carbonatite occurs in a very minor amount as thin veins within the dolomite carbonatite. The age (207Pb/204Pb) of the Sevathur carbonatites is 801 ± 11 Ma, they are emplaced within the Precambrian granulite terrains along NE–SW trending fault systems.

Minor minerals in dolomite carbonatite are fluorapatite, phlogopite (with a kinoshitalite component), amphibole and magnetite. Pyrochlore (rich in UO2), monazite-Ce, and barite are accessory minerals. Dolomite carbonatite at the Sevathur complex contains norsethite, calcioburbankite, and benstonite as inclusions in primary calcite and are interpreted as primary minerals.

They are indicative of Na, Sr, Mg, Ba, and LREE enrichment in their parental carbonatitic magma. Norsethite, calcioburbankite, and benstonite have not been previously known at Sevathur. The hydrothermal processes at the Sevathur carbonatites lead to alteration of pyrochlore into hydropyrochlore, and Ba-enrichment. Also, it leads to formation of monazite-(Ce) and barite-II.
Based on a genetic algorithm, we have solved the problem of finding the parameters of optical Gaussian pulses which make their efficient nonlinear combining possible in one of the peripheral cores of a 7-core hexagonal fibre.

Two approaches based on individual selection of peak powers and field phases of the pulses launched into the fibre are considered.

The found regimes of Gaussian pulse combining open up new possibilities for the development of devices for controlling optical radiation.
One of the aims of new circular collider projects is further increase in their luminosity. A high electromagnetic field of space charge at the meeting points limits the achievable current densities and consequently the luminosity. Non- linear focusing compensation in a storage ring done by the opposite-charge beam circulating in another storage ring was proposed and tested many years ago. Ya. S. Derbenev has shown that such a scheme suffers from tune shifts of coherent betatron oscillations, which move betatron frequencies toward the nearest integer or half-integer resonance. In this paper, the collider based on electron energy recovery linac (ERL) and "figure-8" positron storage ring with beams of equal currents is considered. Positrons are circulating in a two-loop storage ring (positron-positron collider), and electron- electron collider uses ERL, as in original Tigner's proposal. Thus, a collision of four bunches and space-charge compensation in a multi-bunch mode can be ensured. The mathematical and numerical analysis of this configuration is presented.

Ethanol steam reforming catalyst’s precursors, i.e., nanocomposites of complex oxides with the general formula [Pr 0.15 Sm 0.15 Ce 0.35 Zr 0.35 O 2 + LaMn 0.45 Ni 0.45 Ru 0.1 O 3 ] (1:1 by mass), were synthesized by three different methods.

It was shown that two synthesis methods – ultrasonic dispersion and sequential polymeric method, lead to the formation of the nanocomposite perovskite–fluorite system with the specific surface area up to 50 m 2 /g. Reduction of samples at 400–500°C lead to the formation of Ni–Ru alloy nanoparticles strongly bound with the surface of oxide nanocomposite.

Catalytic tests in ethanol steam reforming reaction at 500–600°C showed the highest specific activity of the sample prepared by the sequential polymeric method due to the location of Ni- and Ru-containing perovskite mainly on the surface of the composite providing a high concentration of active metal centers. At higher temperatures for all samples, ethanol conversion approached 100% with hydrogen yield varying in the range of 65–75%. A study of spent catalysts confirmed the absence of carbon deposits after long-term catalytic tests at 650°C.
In the title compound, [ Me C 5 H 4 NCONHCH 2 C 6 H 5 ]I or C 14 H 15 N 2 O + ·I − , a cation and an anion form an ionic pair linked by a strong N—H...I hydrogen bond. In the crystal, ionic pairs linked by weak C—H...I hydrogen bonds form infinite ribbons along the crystallographic a axis.

Polymorphism screening varying crystallization solvents (water, acetone 90%–water, ethanol 90%–water, 2-propanol 90%–water, DMF, DMSO, methanol, acetonitrile) and conditions (solution temperature, heating and cooling protocols) did not reveal any other polymorphs than the one reported in this work.
Coagulation technique was applied for preparation of multiwall carbon nanotube- (MWNT-)containing polystyrene (PSt) composite materials with different MWNT loading (0.5–10 wt.%).

Scanning and transmission electron microscopies were used for investigation of the morphology and structure of produced composites. Electrical conductivity of MWNT/PSt composites was investigated using a four-probe technique. Electromagnetic response of prepared materials was investigated in broadband region (0.01–4 and 26–36 GHz).

It was shown that synthesis of MWNT/PSt composites using coagulation technique allows one to obtain high dispersion degree of MWNT in the polymer matrix. According to microscopy data, composite powder consists of the polystyrene matrix forming spherical particles with diameter ca. 100–200 nm, and the surface of MWNT is strongly wetted by the polymer forming thin layer with 5–10 nm thickness. Observed electrical percolation threshold of composite materials is near to 10 wt.%, mainly due to the insulating polymer layer deposited on the surface of nanotubes. It was found that MWNT/PSt composites are almost radiotransparent for low frequency region and possess high absorbance of EM radiation at higher frequencies.
We study nonlinear stability of radial collapse of a cylindrical shell filled with a viscous incompressible fluid homogeneous in density. We have made the following assumptions: 1) there is a vacuum inside the shell, 2) there is the layer of compressed polytropic gas outside the shell, the gas serves as a product of instant detonation and causes nonzero constant pressure on the outer surface of the shell, 3) there is a vacuum beyond the layer of gas. By the direct Lyapunov method, we state the absolute stability of radial collapse of the viscous cylindrical shell relative to finite disturbances of the same type of symmetry. Namely, we construct a Lyapunov function satisfying all conditions of the Lyapunov first theorem (stability theorem) regardless of radial collapse mode. Thus, we confirm the Trishin hypothesis and prove that cumulation of the fluid kinetic energy during the radial collapse of the cylindrical shell near its geometric axis never originates.

Libellula depressa (Linnaeus, 1758) was recorded from the NW foothills of Altai Mts. at the Inya River near the Chineta Village (51.34° N, 83.05° E) in Kranoshchekovo District of Altai Krai Province, Russia. This record was made for the first time in the territory of Russia, eastward of Urals and in 150 km NNE of the closest locality in East Kazakhstan in Ust’-Kamenogorsk (Oskemen).
In the South Urals, we have identified and investigated two platinum-bearing formations – ophiolite chromitebearing complexes, and the Khudolaz differentiated mafic-ultramafic complex with sulfide Cu-Ni mineralization. The ophiolite chromite-bearing complexes include fragments of the upper mantle and lower crust of the Paleouralian Ocean, which were induced by collision onto the edge of the East European platform. The origin of the Khudolaz complex is related a mantle plume activity.

Here, we review and compare the main features of platinum-metal mineralization (PMM) in these two formations. The article presents the results of mineralogical and geochemical studies of PMM associated with chromite and sulfide Cu-Ni ores. Texture observations using electron microscope and optical (reflected light) images, as well as LA ICP MS analyses of sulfides suggest late- and post-magmatic crystallization of PMM in three phases: (1) immiscible metalloid or highly fractionated residual sulfide melts trapped in sulfides; (2) segregation of isomorphic impurities of platinum group elements (PGE) and chalcogenide elements from sulfide solid solutions; and (3) interaction of hydrothermal fluids with soluble sulfides.

In association with chromitites, two types of PMM are distinguished: (1) predominating refractory platinoids in chromitites of the mantle unit of the section, and (2) predominating platinum and palladium in chromitites of the transitional wehrlite-clinopyroxenite complex. Compositions of platinum group minerals (PGM) and relations between their elements and host minerals suggest that the minerals of the ophiolite chromite-bearing complexes are of a restite origin, while the Khudolaz complex results from a combination of magmatic processes and solid-phase redistribution of material. Palladium (michenerite, froodite, merenskyite, borovskite, sudburyite) and platinum (sperrylite, moncheite) minerals are found in magmatic sulfide ores of the Khudolaz complex, which were subjected to hydrothermal metasomatization. Prospective for PMM are extended bodies of disseminated chromitites in marginal dunites of the Kraka and Nurali massifs, and wehrlite-clinopyroxenite complexes of the same massifs containing PGE (above 500 ppb). In the Khudolaz complex, promising PMM bodies are low-metasomatized parts of sulfide ore bodies (1 ppm of ΣPGE and above) located in the largest massifs, Severny Buskun and Zapadny Karasaz. Exocontact zones of these intrusions are also promising for PMM.
A possible effect of direct CP violation in $D\to K^{0}_{S}\pi^{+}\pi^{-}$ decay on the γ measurement from B ±→DK ±, $D\to K^{0}_{S}\pi^{+}\pi^{-}$ Dalitz plot analysis is considered.

Systematic uncertainty of γ coming from the current limits on direct CP violation in $D\to K^{0}_{S}\pi ^{+}\pi^{-}$ is estimated, and a modified model-independent procedure of B ±→DK ±, $D\to K^{0}_{S}\pi^{+}\pi^{-}$ Dalitz plot analysis is proposed that gives an unbiased γ measurement even in presence of direct CP violation in charm decays.

The technique is applicable to other three-body D decays such as $D^{0}\to K_{S}^{0}K^{+}K^{-}$ , D 0→π + π − π 0, etc.
Decays $D\ensuremath{\rightarrow}{\ensuremath{\pi}}^{+}{\ensuremath{\pi}}^{\ensuremath{-}}{e}^{+}{\ensuremath{\nu}}_{e}$ and ${D}_{s}\ensuremath{\rightarrow}{\ensuremath{\pi}}^{+}{\ensuremath{\pi}}^{\ensuremath{-}}{e}^{+}{\ensuremath{\nu}}_{e}$ serve as probes that check the existence of constituent $q\overline{q}$ components in the wave functions of scalar mesons decaying into ${\ensuremath{\pi}}^{+}{\ensuremath{\pi}}^{\ensuremath{-}}$. There exists a great deal of concrete evidence in favor of the exotic four-quark nature of light scalars. At the same time, the further expansion of the area of the ${q}^{2}{\overline{q}}^{2}$ model validity for light scalars on ever new processes seems extremely interesting and important. We analyze the BESIII and CLEO data on the decays ${D}^{+}\ensuremath{\rightarrow}{\ensuremath{\pi}}^{+}{\ensuremath{\pi}}^{\ensuremath{-}}{e}^{+}{\ensuremath{\nu}}_{e}$ and ${D}_{s}^{+}\ensuremath{\rightarrow}{\ensuremath{\pi}}^{+}{\ensuremath{\pi}}^{\ensuremath{-}}{e}^{+}{\ensuremath{\nu}}_{e}$ and show that the results of these experiments together can be interpreted in favor of the four-quark nature of light scalar mesons $\ensuremath{\sigma}(500)$ and ${f}_{0}(980)$. Our approach can also be applied to the description of other similar decays involving light scalars.
A fourth-order multi-exponential scheme is proposed for the Zakharov-Shabat system. The scheme represents a product of 13 exponential operators. The construction of the scheme is based on a fourth-order three-exponential scheme, which contains only one exponent with a spectral parameter. This exponent is factorized to the fourth-order with the Suzuki formula of 11 exponents. The obtained scheme allows the use of a fast algorithm in calculating the initial problem for a large number of spectral parameters and conserves the quadratic invariant exactly for real spectral parameters.
We present a study of the inclusive photon spectra from 5.9 million J/ψ decays collected with the KEDR detector at the VEPP-4M e+e− collider.

We measure the branching fraction of radiative decay J/ψ → ηcγ, ηc width and mass.

Our preliminary results are: M(ηc) = 2979.4±1.5±1.9 MeV/c2, Γ(ηc) = 27.8±5.1±3.3 MeV, Γ(J/ψ→ ηcγ) = (2.34±0.15±0.40)%.
We study the linear stability of a resting state for a generalization of the basic rheological Pokrovski-Vinogradov model for flows of solutions and melts of an incompressible viscoelastic polymeric medium to the nonisothermal case under the influence of magnetic field. We prove that the corresponding linearized problem describing magnetohydrodynamic flows of polymers in an infinite plane channel has the following property: for certain values of the conduction current which is given on the electrodes, i.e. on the channel boundaries, the problem has solutions whose amplitude grows exponentially (in the class of functions periodic along the channel).
Measurements of charm mixing parameters from the decay-time-dependent ratio of ${D}^{0}\ensuremath{\rightarrow}{K}^{+}{\ensuremath{\pi}}^{\ensuremath{-}}$ to ${D}^{0}\ensuremath{\rightarrow}{K}^{\ensuremath{-}}{\ensuremath{\pi}}^{+}$ rates and the charge-conjugate ratio are reported. The analysis uses data, corresponding to $3\text{ }\text{ }{\mathrm{fb}}^{\ensuremath{-}1}$ of integrated luminosity, from proton-proton collisions at 7 and 8 TeV center-of-mass energies recorded by the LHCb experiment. In the limit of charge-parity ($CP$ ) symmetry, the mixing parameters are determined to be ${x}^{\ensuremath{'}2}=(5.5\ifmmode\pm\else\textpm\fi{}4.9)\ifmmode\times\else\texttimes\fi{}{10}^{\ensuremath{-}5}$, ${y}^{\ensuremath{'}}=(4.8\ifmmode\pm\else\textpm\fi{}1.0)\ifmmode\times\else\texttimes\fi{}{10}^{\ensuremath{-}3}$, and ${R}_{D}=\phantom{\rule{0ex}{0ex}}(3.568\ifmmode\pm\else\textpm\fi{}0.066)\ifmmode\times\else\texttimes\fi{}{10}^{\ensuremath{-}3}$. Allowing for $CP$ violation, the measurement is performed separately for ${D}^{0}$ and ${\overline{D}}^{0}$ mesons yielding ${A}_{D}=(\ensuremath{-}0.7\ifmmode\pm\else\textpm\fi{}1.9)%$, for the direct $CP$-violating asymmetry, and $0.75<|q/p|\phantom{\rule{0ex}{0ex}}<1.24$ at the 68.3% confidence level, for the parameter describing $CP$ violation in mixing. This is the most precise determination of these parameters from a single experiment and shows no evidence for $CP$ violation.
A new synthetic entry to iridium Keggin‐type polyoxometalate complexes from [PW 11 O 39 ] 7– and K 3 [IrCl 6 ] under harsh conditions is reported.

The complex [PW 11 O 39 IrCl] 5– ( 1 5– ) featuring an IrCl functionality was obtained in high yield and characterized by NMR spectroscopic and ESI‐MS techniques. The presence of Li + (3–4 M) is essential for a quantitative yield of 1 5– . The reactivities of 1 5– and its rhodium analogue [PW 11 O 39 RhCl] 5– in ligand substitution at the noble metal site were studied. Thiocyanate coordination successfully yielded (Bu 4 N) 5 [PW 11 O 39 M (SCN)] [ M = Rh ( 2a ), Ir, ( 3a )]. In both cases, the SCN ligands are coordinated by sulfur atoms, according to 13 C NMR and IR spectroscopic data. Gas‐phase fragmentation reactions of compounds 2a and 3a were also investigated by collision‐induced dissociation (CID) experiments.

Reaction of [PW 11 O 39 RhCl] 5– with NaN 3 resulted in Cl – to OH – replacement accompanied by the liberation of the RhCl fragment, whereas 1 5– proved unreactive with NaN 3 . Attempts to coordinate NO 2 – are adversely affected by competing noble metal excision with formation of free [PW 11 O 39 ] 7– .
To reduce emissions of harmful substances into the atmosphere, it is very important to create compact, energy-efficient catalytic units for afterburning volatile organic compounds. A key component of such units is the catalyst cartridge. The efficiency of its operation is provided by the supply of a gas flow with a uniform velocity field. To solve the problem, an experimental model of the gas flow distributor and an aerodynamic stand for its testing were created. A set of wing-shaped inserts was used to align the velocity profile in the rotary section of the model. The form and arrangement of the blades were chosen by numerical simulation. Numerical calculations were verified on the basis of measurement of velocity fields in the model sections.
We reveal that a synthetic photonic lattice based on coupled optical loops can be utilized as a feed-forward neural network for processing of optical pulse sequences in time domain. As a proof of concept, we train the optical system to restore an initial shape of the pulse train from the signal distorted due to linear dispersion in a fiber-optic link. We also show efficient training of the optical network with an intrinsic Kerr-type nonlinearity for the realization of target nonlinear transmission functions and inference functionality for the discrimination of different pulse sequences. The theoretical modeling is performed under practical conditions and can guide future experimental realizations.
Background Triticum kiharae (A t A t GGDD, 2n = 42) is of interest for the improvement of bread wheat as a source of high grain protein and gluten content, as well as resistance to many diseases. The use of T. kiharae for the improvement of T. aestivum L. is complicated by the fact that the homology degree of their genomes is low and this leads to an unbalanced set of chromosomes in the gametes of its first generations and the elimination of some genotypes. The aim of this study was to analyze the nature of alien introgressions and their effect on the cytological stability of hybrids obtained from crossing of bread wheat varieties with T. kiharae.

Results Using C-banding, the presence of entire chromosomes of T. kiharae in the karyotypes of hybrid lines (intergenomic substitution 2G/2B), chromosome arms (centric translocation Т2A t S:2AL) and large inserts in the form of terminal translocations involving chromosomes of 1st, 3rd and 5th homoeologous groups of B- and G-genomes were found. Molecular markers revealed short introgression of T. kiharae into the genome of common wheat varieties. The highest introgression frequency was shown for 1A, 1B, 2A, 5B, and 6A chromosomes, while no foreign chromatin was detected in 4A and 4B chromosomes. A high level of cytological stability (a meiotic index of 88.18–93.0%) was noted for the majority of introgression lines. An exception was found for the lines containing the structural reorganization of chromosome 5B, affecting the main genes of chromosome synapsis in terms of their functioning.

Conclusions During the stabilization of hybrid karyotypes, the introgression of genetic material from T. kiharae into the genome of T. aestivum occurs in the form of short fragments detectable only by molecular markers and in the form of whole chromosomes (intergenomic substitution) and their large fragments (centric and terminal translocations). The level of cytological stability achieved in F 10 by the majority of introgression lines ensures the formation of functional gametes sufficient for the successful reproduction of the obtained hybrids.

Several conjugates of metallophthalocyanines with deoxyribooligonucleotides were synthesized to investigate sequence-specific modification of DNA by them. Oligonucleotide parts of these conjugates were responsible for the recognition of selected complementary sequences on the DNA target.

Metallophthalocyanines were able to induce the DNA modification: phthalocyanines of Zn(II) and Al(III) were active as photosensitizers in the generation of singlet oxygen (1)O(2), while phthalocyanine of Co(II) promoted DNA oxidation by molecular oxygen through the catalysis of formation of reactive oxygen species ((.)O(2) (-), H(2)O(2), OH). Irradiation of the reaction mixture containing either Zn(II)- or Al(III)-tetracarboxyphthalocyanine conjugates of oligonucleotide pd(TCTTCCCA) with light of > 340 nm wavelength (Hg lamp or He/Ne laser) resulted in the modification of the 22-nucleotide target d(TGAATGGGAAGAGGGTCAGGTT). A conjugate of Co(II)-tetracarboxyphthalocyanine with the oligonucleotide was found to modify the DNA target in the presence of O(2) and 2-mercaptoethanol or in the presence of H(2)O(2).

Under both sensitized and catalyzed conditions, the nucleotides G(13)-G(15) were mainly modified, providing evidence that the reaction proceeded in the double-stranded oligonucleotide. These results suggest the possible use of phthalocyanine-oligonucleotide conjugates as novel artificial regulators of gene expression and therapeutic agents for treatment of cancer.
