A Functional Approach to Compiling a Specialized English–Slovene Dictionary of Green Energy Terms

open access: yesELOPE, 2013
The functional approach to lexicography argues that dictionaries must provide their users with concrete types of information, presented in a manner that suits their needs.

On the cosmological mass function theory [PDF]

open access: yes, 2006
This paper provides, from one side, a review of the theory of the cosmological mass function from a theoretical point of view, starting from the seminal paper of Press & Shechter (1974) to the last developments (Del Popolo & Gambera (1998, 1999), Sheth &

Artifact as a Node of Heterogeneous Relationships: A Study with Traditional Natural Packaging in Cooking and Food Preparation Practices in Antioquia, Colombia

open access: yesPhilosophies, 2022
This article studies natural food packaging as enabling artifacts of the traditional material culture of Antioquia in Colombia. For this purpose, we consider artifacts as objective nodes that combine design and use intentions, functions, materials ...

Scaled Density Functional Theory Correlation Functionals [PDF]

open access: yesThe Journal of Physical Chemistry A, 2007
We show that a simple one-parameter scaling of the dynamical correlation energy estimated by the density functional theory (DFT) correlation functionals helps increase the overall accuracy for several local and nonlocal functionals. The approach taken here has been described as the "scaled dynamical correlation" (SDC) method [Ramachandran, J.

ON THE BEST APPROXIMATION OF THE DIFFERENTIATION OPERATOR

open access: yesUral Mathematical Journal, 2015
In this paper we give a solution of the problem of the best approximation in the uniform norm of the differentiation operator of order k by bounded linear operators in the class of functions with the property that the Fourier transforms of their ...

Function theory and multiplicative linear functionals [PDF]

open access: yesTransactions of the American Mathematical Society, 1965
The principal result of this paper is that HO is a logmodular algebra on the maximal ideal space of Lw(m), i.e., that each real-valued function in L(m) is the logarithm of the modulus of an invertible function in the algebra H'. This enables us to deduce from (a) and (b) the bulk of the generalized analytic function theory which is valid for logmodular

Operator theory and function theory in Drury-Arveson space and its quotients [PDF]

open access: yes, 2014
The Drury-Arveson space $H^2_d$, also known as symmetric Fock space or the $d$-shift space, is a Hilbert function space that has a natural $d$-tuple of operators acting on it, which gives it the structure of a Hilbert module.

Density-functional theory on graphs [PDF]

open access: yesThe Journal of Chemical Physics, 2021
The principles of density-functional theory are studied for finite lattice systems represented by graphs. Surprisingly, the fundamental Hohenberg–Kohn theorem is found void, in general, while many insights into the topological structure of the density-potential mapping can be won.

Spherical potential functional theory [PDF]

open access: yesThe Journal of Chemical Physics, 2021
According to a recent theorem of Theophilou [J. Chem. Phys. 149, 074104 (2018)], a set of spherically symmetric densities determines uniquely the external potential in molecules and solids. This theorem leads to a fresh formulation of density functional theory.
