Numerical simulation of surface waves instability on a discrete grid
We perform full-scale numerical simulation of instability of weakly nonlinear
waves on the surface of deep fluid. We show that the instability development
leads to chaotization and formation of wave turbulence.
We study instability both of propagating and standing waves. We studied
separately pure capillary wave unstable due to three-wave interactions and pure
gravity waves unstable due to four-wave interactions. The theoretical
description of instabilities in all cases is included into the article. The
numerical algorithm used in these and many other previous simulations performed
by authors is described in details.Comment: 47 pages, 40 figure

The multicomponent condensation of aromatic aldehydes, acetoacetanilides, cyanothioacetamide, alkylatingΒ agents and morpholine in ethanol at 20Β°C was first synthesized to formation of substituted 4-aryl-N-aryl(3-pyridinyl)-5-cyano-6-(3,4-dihydroxybenzoylmethylsulphanyl)-2-methylnicotinamides, 6-allylsulphanyl-N-(4-chlorophenyl)-5-cyano-2-methyl-4-(3-pyridinyl)-1,4-dihydronicotinamide and 6-carbamoylmethylsulphanyl-N-(4-chlorophenyl)-Β 5-cyano-2-methyl-4-(4-pyridinyl)-1,4-dihydronicotinamide. In the first step Knoevenagel reaction produces theΒ alkene which is then reacted with a Michael anilide acetoacetate to form the corresponding adduct. Last reactionΒ conditions chemoselectively intramolecularly cyclized to substituted morpholinium tetrahydropyridinthiolate.Β Elimination of the water the latter leads to the formation of salt, the arises capable aromatization andΒ alkylation of 3,4-dihydroxyphenacylbromide. Introduction this condensation as alkylating reagent allylbromideΒ or Ξ±-chloroacetamide ends form the corresponding 1,4-dihydronicotinamide. The structure of the synthesizedΒ compounds was proved by IR-, 1H NMR- and chromatommas-spectrometry. Synthesized substances tested forΒ anti-radical and membrane-stabilizing action. Revealed their high antiradical activity at a concentration of 10-1-10-3 mol/L compared with nicotinamide.ΠΠ½ΠΎΠ³ΠΎΠΊΠΎΠΌΠΏΠΎΠ½Π΅Π½ΡΠ½ΠΎΠΉ ΠΊΠΎΠ½Π΄Π΅Π½ΡΠ°ΡΠΈΠ΅ΠΉ Π°ΡΠΎΠΌΠ°ΡΠΈΡΠ΅ΡΠΊΠΈΡ

Mesoscopic wave turbulence
We report results of sumulation of wave turbulence. Both inverse and direct
cascades are observed. The definition of "mesoscopic turbulence" is given. This
is a regime when the number of modes in a system involved in turbulence is high
enough to qualitatively simulate most of the processes but significantly
smaller then the threshold which gives us quantitative agreement with the
statistical description, such as kinetic equation. Such a regime takes place in
numerical simulation, in essentially finite systems, etc.Comment: 5 pages, 11 figure
Crystal lattice engineering the novel substrates for III-nitride-oxide heterostructures
In this work, we firstly investigated controlling the lattice parameter of IIIoxides
used as substrates for III-nitrides heterostructures. It was shown that the atomic
content change in III-sublattice gives large possibilities for precise cation controlling the
lattice parameters. The developed technique is promising to make ideal substrates in IIInitride
epitaxy of LED, LD and transistors with a high quantum efficiency and small
noise. This technology can be realized using MBE, MOSVD or CVD chloride-hydride
epitaxy with computer driving
Weak Turbulent Kolmogorov Spectrum for Surface Gravity Waves
We study the long-time evolution of gravity waves on deep water exited by the
stochastic external force concentrated in moderately small wave numbers. We
numerically implement the primitive Euler equations for the potential flow of
an ideal fluid with free surface written in canonical variables, using
expansion of the Hamiltonian in powers of nonlinearity of up to fourth order
terms.
We show that due to nonlinear interaction processes a stationary energy
spectrum close to is formed. The observed spectrum can be
interpreted as a weak-turbulent Kolmogorov spectrum for a direct cascade of
energy.Comment: 4 pages, 5 figure
Solitary wave interaction in a compact equation for deep-water gravity waves
In this study we compute numerical traveling wave solutions to a compact
version of the Zakharov equation for unidirectional deep-water waves recently
derived by Dyachenko & Zakharov (2011) Furthermore, by means of an accurate
Fourier-type spectral scheme we find that solitary waves appear to collide
elastically, suggesting the integrability of the Zakharov equation.Comment: 8 pages, 5 figures, 23 references. Other author's papers can be
