Non-Linear Inner Structure of Topological Vector Spaces

open access: yesMathematics, 2021
Inner structure appeared in the literature of topological vector spaces as a tool to characterize the extremal structure of convex sets. For instance, in recent years, inner structure has been used to provide a solution to The Faceless Problem and to ...

Graph-based linear scaling electronic structure theory [PDF]

open access: yes, 2016
We show how graph theory can be combined with quantum theory to calculate the electronic structure of large complex systems. The graph formalism is general and applicable to a broad range of electronic structure methods and materials, including ...

Assessment of line differentiation in the Thoroughbred horse breed using DNA microsatellite loci

open access: yesВавиловский журнал генетики и селекции, 2019
The Thoroughbred (TB) horse is the best racehorse breed used in the racing industry. This breed has had a closed studbook for about 300 years. In Russia TB horses have been bred since the second half of the XVIII century.

The University – a Rational-Biologic Model [PDF]

open access: yesTheoretical and Applied Economics, 2008
The article advances the extension of the biologic rational model for the organizations, which are reprocessing and living in a turbulent environment. The current “tree” type organizations are not able to satisfy the requirements of the socio-economical ...

Optically induced lattice deformations, electronic structure changes, and enhanced superconductivity in YBa2Cu3O6.48

open access: yesStructural Dynamics, 2017
Resonant optical excitation of apical oxygen vibrational modes in the normal state of underdoped YBa2Cu3O6+x induces a transient state with optical properties similar to those of the equilibrium superconducting state. Amongst these, a divergent imaginary

Structure theorems for linear and non-linear differential operators admitting invariant polynomial subspaces [PDF]

open access: yes, 2006
In this paper we derive structure theorems that characterize the spaces of linear and non-linear differential operators that preserve finite dimensional subspaces generated by polynomials in one or several variables.

Nuclear linear-chain structure arises in carbon-14

open access: yesCommunications Physics, 2023
The shape and internal structure of an atomic nucleus can change significantly with increasing excitation energy, angular momentum, or isospin asymmetry.

Non‐linear capital structure dynamics [PDF]

open access: yesJournal of Business Finance & Accounting, 2022
AbstractWe investigate the capital structure and the dynamic behaviour of firms' debt ratios in a large sample of companies from 52 countries. Our findings support a complex view of capital structure decisions, with firm, macroeconomic and institutional factors interacting in the determination of both the optimal leverage and the adjustment process ...

1,3,5-Triaryl-1,3,5-Triazinane-2,4,6-Trithiones: Synthesis, Electronic Structure and Linear Optical Properties

open access: yesMolecules, 2020
The synthesis of four new 1,3,5-triaryl-1,3,5-triazinane-2,4,6-trithione derivatives (thioisocyanurates) and two new partially thionated analogues from the corresponding 1,3,5-triaryl-1,3,5-triazinane-2,4,6-triones (isocyanurates) is reported, together ...
