Lower Bound of the Complexity of Seven-Valued Functions in the Class of Polarized Polynomials

open access: yesИзвестия Иркутского государственного университета: Серия "Математика", 2017
One of the directions of the investigation of functions over finite fields is the study of their representations, including polynomial ones. In the area of polynomial representations of functions the problem of estimating the complexity of such ...

Analysis of polarization characteristics of freeform surface optical system [PDF]

open access: yesITM Web of Conferences, 2022
Freeform surfaces are widely used in off-axis optical systems with large aperture, large field of view, and long focal length. The polarization effect caused by the non-rotationally symmetrical shape has an impact on the system’s polarization imaging ...

Evaluating the Tutte Polynomial for Graphs of Bounded Tree-Width [PDF]

open access: yes, 1998
It is known that evaluating the Tutte polynomial, $T(G; x, y)$, of a graph, $G$, is $\#$P-hard at all but eight specific points and one specific curve of the $(x, y)$-plane.

Observation on the absorption of linearly polarized light by 133Cs atoms with optically resolved hyperfine structure

open access: yesResults in Physics, 2022
The absorption of linearly polarized light by 133Cs atoms is desired to be well known in many applications of atomic physics. For implementing this requirement, a simplified analytical form for the absorption of linearly polarized light by 133Cs atoms ...

Nanoscale Confinement Enhances Ultrafast Demagnetization. [PDF]

open access: yesAdv Sci (Weinh)
Next generation spintronics may depend on successfully combining femtosecond spin dynamics with nanoscale device miniaturization. We address this by systematically studying the effect of nanoscale confinement on the femtosecond demagnetization of Iron. By combining ultrafast experiments sensitive to spins, charge carriers, and phonons, we uncover a nm ...

On Length of Boolean Functions of a Small Number of Variables in the Class of Pseudo-Polynomials

open access: yesИзвестия Иркутского государственного университета: Серия "Математика", 2020
Minimization of Boolean functions in their various representations is required in logic design of digital devices. EXOR sums (polynomial forms) are considered among other representations.

Spectral Reconstruction Using an Iteratively Reweighted Regulated Model from Two Illumination Camera Responses

open access: yesSensors, 2021
An improved spectral reflectance estimation method was developed to transform captured RGB images to spectral reflectance. The novelty of our method is an iteratively reweighted regulated model that combines polynomial expansion signals, which was ...

Polynomial cubic splines with tension properties [PDF]

open access: yes, 2010
In this paper we present a new class of spline functions with tension properties. These splines are composed by polynomial cubic pieces and therefore are conformal to the standard, NURBS based CAD/CAM ...

An Algorithm for Minimization of Boolean Functions in the Class of Toffoli Reversible Logic Circuits [PDF]

open access: yesИзвестия Иркутского государственного университета: Серия "Математика", 2018
In this paper, the problem of Boolean function's representation by the reversible circuits constructed of the Toffoli gates is considered. Interest in this problem is connected with actual studies of the possibility for realization of "cold" computations.
