Genetic diversity and evolution of closteroviruses

diversity

Karasev AV.
GSID: XIQbu1NzR7QJ
AV Karasev - Annual review of phytopathology, 2000 - annualreviews.org

… In this review, I attempt to analyze this diversity in comparison among the three subgroups, to reliably assess mechanisms and possible directions of the extensive evolution in the family Closteroviridae. This apparently on-going evolution poses potential threats to...

Restoration of images degraded by underwater turbulence using structure tensor oriented image quality (STOIQ) metric.

Optics express

Kanaev AV, Hou W, Restaino SR, Matt S, Gładysz S.
PMID: 26191716
Opt Express. 2015 Jun 29;23(13):17077-90. doi: 10.1364/OE.23.017077.

Recent advances in image processing for atmospheric propagation have provided a foundation for tackling the similar but perhaps more complex problem of underwater imaging, which is impaired by scattering and optical turbulence. As a result of these impairments underwater...

Synthesis and Antimicrobial Activity of 6-Thioxo-6,7-dihydro-2H-[1,2,4]triazino[2,3-c]-quinazolin-2-one Derivatives.

Potassium 8-R(1)-9-R(2)-10-R(3)-3-R-2-oxo-2H-[1,2,4]triazino[2,3-c]quinazoline-6-thiolates 2.1-2.26 were synthesized via cyclocondensation of 6-R-3-(3-R(1)-4-R(2)-5-R(3)-aminophenyl)-1,2,4-triazin-5-ones 1.1-1.26 with carbon disulfide, potassium hydroxide, and ethanol or with potassium O-ethyl dithiocarbonate in 2-propanol. The corresponding thiones 3.1-3.26 were obtained by treatment of 2.1-2.26 with hydrochloric acid. It was...

Strong anisotropy of superexchange in the copper-oxygen chains of La(14)-xCaxCu24O41.

Physical review letters

Kataev V, Choi KY, Grüninger M, Ammerahl U, Büchner B, Freimuth A, Revcolevschi A.
PMID: 11290063
Phys Rev Lett. 2001 Mar 26;86(13):2882-5. doi: 10.1103/PhysRevLett.86.2882.

Electron spin resonance data of Cu2+ ions in La(14)-xCaxCu24O41 single crystals (x = 9,11,12) reveal a very large width of the resonance line in the paramagnetic state. This signals an unusually strong anisotropy of approximately 10% of the isotropic...

Text compression via alphabet re-representation.

Neural networks : the official journal of the International Neural Network Society

Long PM, Natsev AI, Vitter JS.
PMID: 12662681
Neural Netw. 1999 Jun;12(4):755-765. doi: 10.1016/s0893-6080(99)00022-2.

This article introduces the concept of alphabet re-representation in the context of text compression. We consider re-representing the alphabet so that a representation of a character reflects its properties as a predictor of future text. This enables us to...

Autocatalytic model of oscillatory zoning in experimentally grown (Ba,Sr)SO4 solid solution.

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

Katsev S, L'Heureux I.
PMID: 12513383
Phys Rev E Stat Nonlin Soft Matter Phys. 2002 Dec;66(6):066206. doi: 10.1103/PhysRevE.66.066206. Epub 2002 Dec 12.

Oscillatory zoning (OZ) is a phenomenon common to many natural minerals whereby the mineral composition varies more or less regularly from the core of the crystal to its rim. Oscillatory zoned barite-celestite (Ba,Sr)SO4 crystals are one of the very...

Genetic Diversity and Evolution of Closteroviruses.

Annual review of phytopathology

Karasev AV.
PMID: 11701845
Annu Rev Phytopathol. 2000 Sep;38:293-324. doi: 10.1146/annurev.phyto.38.1.293.

The family Closteroviridae comprises more than 30 plant viruses with flexuous, filamentous virions and includes representatives with either mono- or bipartite positive-strand ssRNA genomes. Closteroviruses are transmitted semipersistently by insects from three families of Homoptera, in infected plants are...

Monte Carlo and Multicomponent Approximation Methods for Vector Radiative Transfer by use of Effective Mueller Matrix Calculations.

Applied optics

Tynes HH, Kattawar GW, Zege EP, Katsev IL, Prikhach AS, Chaikovskaya LI.
PMID: 18357013
Appl Opt. 2001 Jan 20;40(3):400-12. doi: 10.1364/ao.40.000400.

For single scattering in a turbid medium, the Mueller matrix is the 4 x 4 matrix that multiplies the incident Stokes vector to yield the scattered Stokes vector. This matrix contains all the information that can be obtained from...

Left-handed interfaces for electromagnetic surface waves.

Physical review letters

Kats AV, Savel'ev S, Yampol'skii VA, Nori F.
PMID: 17359023
Phys Rev Lett. 2007 Feb 16;98(7):073901. doi: 10.1103/PhysRevLett.98.073901. Epub 2007 Feb 16.

We show that surface electromagnetic waves (SEMWs) propagating along two-dimensional (2D) interfaces separating different metamaterials can behave analogously to 3D electromagnetic waves in either usual or left-handed media, depending on the permeabilities and/or permittivities of the two materials forming...

Canonical description of ideal magnetohydrodynamic flows and integrals of motion.

In the framework of the variational principle the canonical variables describing magnetohydrodynamic (MHD) flows of general type (i.e., with spatially varying entropy and nonzero values of all topological invariants) are introduced. It is shown that the velocity representation of...
