Effective coupling of cyclotron autoresonance maser and "gyrotron" modes on a phase-synchronized electron beam.

Physical review. E, Statistical physics, plasmas, fluids, and related interdisciplinary topics

Savilov AV, Bratman VL, Phelps AD, Samsonov SV.
PMID: 11088948
Phys Rev E Stat Phys Plasmas Fluids Relat Interdiscip Topics. 2000 Sep;62(3):4207-15. doi: 10.1103/physreve.62.4207.

For a cyclotron resonance maser (CRM) with a helical axis-encircling electron beam, the possibility of a strong interaction between cutoff (gyrotron) and traveling Doppler-up-shifted (cyclotron autoresonance maser) modes, which are in resonance with the electrons at the same frequency,...

Dissolution of uranium dioxide in supercritical fluid carbon dioxide.

Chemical communications (Cambridge, England)

Samsonov MD, Wai CM, Lee SC, Kulyako Y, Smart NG.
PMID: 12240354
Chem Commun (Camb). 2001 Sep 21;(18):1868-9. doi: 10.1039/b103468p.

Uranium dioxide can be dissolved in supercritical CO2 with a CO2-philic TBP-HNO3 complexant to form a highly soluble UO2(NO3)(2).2TBP complex; this new method of dissolving UO2 that requires no water or organic solvent may have important applications for reprocessing...

Dispersion of helically corrugated waveguides: analytical, numerical, and experimental study.

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

Burt G, Samsonov SV, Ronald K, Denisov GG, Young AR, Bratman VL, Phelps AD, Cross AW, Konoplev IV, He W, Thomson J, Whyte CG.
PMID: 15600525
Phys Rev E Stat Nonlin Soft Matter Phys. 2004 Oct;70(4):046402. doi: 10.1103/PhysRevE.70.046402. Epub 2004 Oct 07.

Helically corrugated waveguides have recently been studied for use in various applications such as interaction regions in gyrotron traveling-wave tubes and gyrotron backward-wave oscillators and as a dispersive medium for passive microwave pulse compression. The paper presents a summary...

Nonlinear layered lattice model and generalized solitary waves in imperfectly bonded structures.

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

Khusnutdinova KR, Samsonov AM, Zakharov AS.
PMID: 19518581
Phys Rev E Stat Nonlin Soft Matter Phys. 2009 May;79(5):056606. doi: 10.1103/PhysRevE.79.056606. Epub 2009 May 13.

We study nonlinear waves in a two-layered imperfectly bonded structure using a nonlinear lattice model. The key element of the model is an anharmonic chain of oscillating dipoles, which can be viewed as a basic lattice analog of a...

Methods for Acquisition of Quantitative Data from Confocal Images of Gene Expression in situ.

Cell and tissue biology

Surkova SY, Myasnikova EM, Kozlov KN, Samsonova AA, Reinitz J, Samsonova MG.
PMID: 19343098
Cell tissue biol. 2008 Apr;2(2):200-215. doi: 10.1134/S1990519X08020156.

In this review, we summarize original methods for the extraction of quantitative information from confocal images of gene-expression patterns. These methods include image segmentation, the extraction of quantitative numerical data on gene expression, and the removal of background signal...

Naimark-dilated PT-symmetric brachistochrone.

Physical review letters

Günther U, Samsonov BF.
PMID: 19113530
Phys Rev Lett. 2008 Dec 05;101(23):230404. doi: 10.1103/PhysRevLett.101.230404. Epub 2008 Dec 05.

The quantum mechanical brachistochrone system with a PT-symmetric Hamiltonian is Naimark-dilated and reinterpreted as a subsystem of a Hermitian system in a higher-dimensional Hilbert space. This opens a way to a direct experimental implementation of the recently hypothesized PT-symmetric...

Highly absorptive coating for the vacuum ultraviolet range.

Applied optics

Moldosanov KA, Samsonov MA, Kim LS, Henneck R, Siegmund OH, Warren J, Cully S, Marsh D.
PMID: 18268564
Appl Opt. 1998 Jan 01;37(1):93-7. doi: 10.1364/ao.37.000093.

We have developed new, highly absorptive coatings for the vacuum UV wavelength range. These coatings display two distinct granularity scales: large structures of a 10-100-microm scale form efficient light traps, upon which are superimposed structures of a submicrometer scale....

Rev Sci Instrum. 2010 Oct;81(10):103304. doi: 10.1063/1.3488354.

A U.S./Russian collaboration of accelerator scientists was directed to the development of high averaged-current (∼1 mA) and high-quality (emittance ∼15 πmm mrad; energy spread ∼0.1%) 1.75 MeV proton beams to produce active interrogation beams that could be applied to...

PT-symmetric quantum state discrimination.

The objective of this paper is to explain and elucidate the formalism of PT quantum mechanics by applying it to a well-known problem in conventional Hermitian quantum mechanics, namely the problem of state discrimination. Suppose that a system is...
