Functional Form of the Imaginary Part of the Atomic Polarizability
, 2015 The dynamic atomic polarizability describes the response of the atom to incoming electromagnetic radiation. The functional form of the imaginary part of the polarizability for small driving frequencies omega has been a matter of long-standing discussion,

Tests of Functional Form and Heteroscedasticity [PDF]
This paper considers tests of misspecification in a heteroscedastic transformation model. We derive Lagrange multiplier (LM) statistics for (i) testing functional form and heteroscedasticity jointly, (ii) testing functional form in the presence of ...

Mitochondrial form and function [PDF]
Nature, 2014 Mitochondria are one of the major ancient endomembrane systems in eukaryotic cells. Owing to their ability to produce ATP through respiration, they became a driving force in evolution. As an essential step in the process of eukaryotic evolution, the size of the mitochondrial chromosome was drastically reduced, and the behaviour of mitochondria within ...

Using Fuzzy Logic to Evaluate Normalization Completeness for An Improved Database Design
, 2012 A new approach, to measure normalization completeness for conceptual model, is introduced using quantitative fuzzy functionality in this paper. We measure the normalization completeness of the conceptual model in two steps.

A simple functional form for proton-${}^{208}$Pb total reaction cross sections [PDF]
, 2001 A simple functional form has been found that gives a good representation of the total reaction cross sections for the scattering from ${}^{208}$Pb of protons with energies in the range 30 to 300 MeV.Comment: 7 pages, 2 ...

Functional treatment of quantum scattering via the dynamical principle [PDF]
, 2006 A careful functional treatment of quantum scattering is given using Schwinger's dynamical principle which involves a functional differentiation operation applied to a generating functional written in closed form.

Transporter oligomerization: form and function [PDF]
Biochemical Society Transactions, 2016 Transporters are integral membrane proteins with central roles in the efficient movement of molecules across biological membranes. Many transporters exist as oligomers in the membrane. Depending on the individual transport protein, oligomerization can have roles in membrane trafficking, function, regulation and turnover. For example, our recent studies

Sign Systems Studies, 2019 The main aim of this article is to show how a possible theoretical articulation between Uexküll’s notion of Funktionskreis and the stratificational model of semiotic structures proposed by Louis Hjelmslev can be made.

Localized form of Fock terms in nuclear covariant density functional theory
, 2012 In most of the successful versions of covariant density functional theory in nuclei, the Fock terms are not included explicitly, which leads to local functionals and forms the basis of their widespread applicability at present.

Biomimetic peptide self-assembly for functional materials
Nature Reviews Chemistry, 2020 Natural biomolecular systems have evolved to form a rich variety of supramolecular materials and machinery fundamental to cellular function. The assembly of these structures commonly involves interactions between specific molecular building blocks, a ...
