[Theory and practice of the morphometry of human tumors].

Arkhiv patologii

Lushnikov EF, Zagrebin VM.
PMID: 3328593
Arkh Patol. 1987;49(12):3-9.

It is stated that if adequate qualitative and quantitative knowledge of tumor development is to be gained, a systems approach must be used, in which a given process is considered as representing the sum total of hierarchically organized and...

Singular self-preserving regimes of coagulation processes.

Physical review. E, Statistical, nonlinear, and soft matter physics

Lushnikov AA, Kulmala M.
PMID: 12005834
Phys Rev E Stat Nonlin Soft Matter Phys. 2002 Apr;65(4):041604. doi: 10.1103/PhysRevE.65.041604. Epub 2002 Apr 02.

The late stages of the time evolution of disperse systems when either coagulation alone governs the temporal changes of particle mass spectra or simultaneous condensation complicates the evolution process are studied under the assumption that the condensation efficiencies and...

Analytical kinetics of clustering processes with cooperative action of aggregation and fragmentation.

Physical review. E, Statistical, nonlinear, and soft matter physics

Dubovik VM, Galperin AG, Richvitsky VS, Lushnikov AA.
PMID: 12241429
Phys Rev E Stat Nonlin Soft Matter Phys. 2002 Jul;66(1):016110. doi: 10.1103/PhysRevE.66.016110. Epub 2002 Jul 16.

Some models of clustering processes are formulated and analytically solved employing generating functions methods. Those models include events that result from combined action of the coagulation and fragmentation processes. Fragmentation processes of two kinds, so-called similar and arbitrary, ones,...

Polydimethylsiloxane bilayer films with an embedded spontaneous curvature.

Soft matter

Egunov AI, Korvink JG, Luchnikov VA.
PMID: 26539638
Soft Matter. 2016 Jan 07;12(1):45-52. doi: 10.1039/c5sm01139f.

Elastomer polydimethylsiloxane (PDMS) films with embedded in-plane gradient stress are created by making PDMS/(PDMS + silicone oil) crosslinked bilayers and extracting the oil in a suitable organic solvent bath. The collapse of the elastomer after oil extraction generates differential...

Exact kinetics of sol-gel transition in a coagulating mixture.

Physical review. E, Statistical, nonlinear, and soft matter physics

Lushnikov AA.
PMID: 16605602
Phys Rev E Stat Nonlin Soft Matter Phys. 2006 Mar;73(3):036111. doi: 10.1103/PhysRevE.73.036111. Epub 2006 Mar 07.

The formation of a gel in a two component disperse system wherein binary coagulation governs the temporal changes to particle composition spectra is studied under the assumption that the coagulation kernel is proportional to m1n2+m2n1, with m,n being the...

Inhomogeneity of the spatial distribution of vibrational modes in a computer model of amorphous argon.

Physical review. B, Condensed matter

Luchnikov VA, Medvedev NN, Naberukhin YI, Novikov VN.

Machine Learning Non-Markovian Quantum Dynamics.

Physical review letters

Luchnikov IA, Vintskevich SV, Grigoriev DA, Filippov SN.
PMID: 32338970
Phys Rev Lett. 2020 Apr 10;124(14):140502. doi: 10.1103/PhysRevLett.124.140502.

Machine learning methods have proved to be useful for the recognition of patterns in statistical data. The measurement outcomes are intrinsically random in quantum physics, however, they do have a pattern when the measurements are performed successively on an...

Excess of L-alanine in amino acids synthesized in a plasma torch generated by a hypervelocity meteorite impact reproduced in the Laboratory.

Planetary and space science

Managadze GG, Engel MH, Getty S, Wurz P, Brinckerhoff WB, Shokolov AG, Sholin GV, Terent'ev SA, Chumikov AE, Skalkin AS, Blank VD, Prokhorov VM, Managadze NG, Luchnikov KA.
PMID: 32818000
Planet Space Sci. 2016 Oct 15;131:70-78. doi: 10.1016/j.pss.2016.07.005. Epub 2016 Jul 26.

We present a laboratory reproduction of hypervelocity impacts of a carbon containing meteorite on a mineral substance representative of planetary surfaces. The physical conditions of the resulting impact plasma torch provide favorable conditions for abiogenic synthesis of protein amino...
