Petrological-geochemical features of ore-bearing effusive and intrusive rocks of the Nikolaevskoe gold-porphyry deposit (the Southern Urals)

open access: yesЛитосфера, 2018
Object. The article considers the results of geochemical studies of ore-bearing effusive and intrusive rocks of the Nikolaevka gold deposit, located in the zone of the Main Uralian fault in the Southern Urals.

Matrix Representations for Symmetric and Antisymmetric Multi-Linear Maps [PDF]

open access: yesarXiv, 2010
In this paper the main results in arXiv:0901.3179v3, related to the matrix representation of polynomial maps, are restated in traditional way of linear algebra assuming that variable vectors are presented as column vectors. Some new results related to that subject are also included. Here one can find the behavior of the matrices of polynomial maps with

Reversal and tunability of the surface plasmon enhanced optical forces on a nanorod pair in the presence of a dielectric interlayer [PDF]

open access: yesarXiv, 2013
We investigate numerically the modification of surface-plasmon assisted optical force on a gold nanorod pair by incorporating dielectric interlayer. The frequency dependent electromagnetic forces are obtained through full-vectorial solution of Maxwell equations with a finite element solver.

On relation between rational and differential rational invariants of surfaces with respect to the motion groups [PDF]

open access: yesarXiv, 2015
The description of invariants of surfaces with respect to the motion groups is reduced to the description of invariants of parameterized surfaces with respect to the motion groups. Existence of a commuting system of invariant partial differential operators (derivatives) and a finite system of invariants, such that any invariant of the surface is a ...

Mityagin's Extension Problem. Progress Report [PDF]

open access: yesarXiv, 2016
Given a compact set $K\subset {\Bbb R}^d,$ let ${\mathcal E}(K)$ denote the space of Whitney jets on $K$. The compact set $K$ is said to have the extension property if there exists a continuous linear extension operator $W:{\mathcal E}(K) \longrightarrow C^{\infty}({\Bbb R}^d)$. In 1961 B. S.
