Properties of the density functional response kernels and its implications on chemistry.

Publication Type: Academic Journal

Source(s): Journal of Chemical Physics. 9/21/2022, Vol. 157 Issue 11, p1-20. 20p.

Abstract: An overview of mathematical properties of the non-local second order derivatives of the canonical, grand canonical, isomorphic, and grand isomorphic ensembles is given. The significance of their positive or negative semidefiniteness and the implication...

Tangentially driven active polar linear polymers—An analytical study.

Publication Type: Academic Journal

Source(s): Journal of Chemical Physics. 11/21/2022, Vol. 157 Issue 19, p1-14. 14p.

Abstract: The conformational and dynamical properties of isolated flexible active polar linear polymers (APLPs) are studied analytically. The APLPs are modeled as Gaussian bead-spring linear chains augmented by tangential active forces, both in a discrete and co...

Multiplicative Dirac system.

Publication Type: Academic Journal

Source(s): Kuwait Journal of Science. Jul2022, Vol. 49 Issue 3, p1-11. 11p.

Abstract: We define a Dirac system in multiplicative calculus by some algebraic structures. Asymptotic estimates for eigenfunctions of the multiplicative Dirac system are obtained. Eventually, some fundamental properties of the multiplicative Dirac system are ex...

Plegar el pliegue. Una aproximación al desafío transhumanista en clave de Neobarroco.

Publication Type: Academic Journal

Source(s): Hipogrifo: revista de literatura y cultura del siglo de oro. 2022, Vol. 10 Issue 2, p17-33. 17p.

Abstract: El presente artículo parte de una incursión historiográfica en las fi- losofías barrocas de G. W. Leibniz y Baltasar Gracián, mediada por los estudios de Gilles Deleuze sobre el Barroco y el concepto de «pliegue». A partir de ahí, se tratará de ofrecer...

Environmental considerations in ab initio calculations of electronic states of PtCl4−2 complexes.

Publication Type: Academic Journal

Source(s): Journal of Chemical Physics; 1/14/2023, Vol. 158 Issue 2, p1-9, 9p

Abstract: Copyright of Journal of Chemical Physics is the property of American Institute of Physics and its content may not be copied or emailed to multiple sites or posted to a listserv without the copyright holder's express written permission. However, users m...

Strategie nazewnicze wobec kreowanych światów w prozie Olgi Tokarczuk.

Publication Type: Academic Journal

Source(s): Ruch Literacki. 2022, Vol. 63 Issue 3, p409-427. 19p.

Authors:

Abstract: This article deals with the function of proper names in Olga Tokarczuk's novel Anna In w grobowcach świata [Anna In in the Tombs of the World] and the short story collection Opowiadania bizarne [Bizarre Stories]. In either case we are confronted with a...

The neutrosophic integrals by partial fraction.

Publication Type: Academic Journal

Source(s): Neutrosophic Sets & Systems. 2022, Vol. 49, p438-457. 20p.

Abstract: The purpose of this article is to study the neutrosophic integrals by partial fraction, where the neutrosophic fraction function is defined, in addition, four cases of the neutrosophic proper rational function were discussed, also, integral of the neut...

Evaluation of Coefficients of Mode III Crack-Tip Asymptotic Fields Using Weak Form Quadrature Elements.

Publication Type: Academic Journal

Source(s): Journal of Engineering Mechanics. Jan2023, Vol. 149 Issue 1, p1-11. 11p.

Abstract: A weak form quadrature element formulation is established to obtain the coefficients of Mode III crack-tip asymptotic fields. The problem domain is divided into circular subdomains near the crack tips and several integrable normal subdomains elsewhere....

Step-by-Step Penalized Blind Kriging Methods for Surrogate Modeling.

Publication Type: Academic Journal

Source(s): Mathematical Problems in Engineering. 1/21/2022, p1-8. 8p.

Abstract: When building a surrogate model, it is important to identify a proper mean function for the kriging model. The commonly used variable selection method is the penalized blind kriging (PBK) method. But this method could lead to a low time efficiency, whi...

Koopman Linear Quadratic Regulator Using Complex Eigenfunctions for Nonlinear Dynamical Systems.

Publication Type: Academic Journal

Source(s): SIAM Journal on Applied Dynamical Systems. 2022, Vol. 21 Issue 4, p2463-2486. 24p.

Abstract: Koopman operator theory has gained interest in the past decade as a framework for rigorously transforming nonlinear dynamics on the state space into linear dynamics on Koopman-invariant function spaces. These Koopman-invariant spaces can be approximate...
