Novel co-occurrence of functionally redundant consumers induced by range expansion alters community structure.
Ongoing climate change is shifting the geographic distributions of some species, potentially imposing rapid changes in local community structure and ecosystem functioning. Besides changes in population-level interspecific ...
Magnetic exchange couplings with range-separated hybrid density functionals
(American Chemical Society, 2010-06)
We investigate the effect of Hartree-Fock range-separation on the calculation of magnetic exchange couplings in a set of nine bimetallic transition-metal complexes containing 3d elements (V, Cr, Mn, and Cu). To this end, ...
Trapping of a particle in a short-range harmonic potential well
(2013-01-01)
Eigenstates of a particle in a localized and unconfined harmonic potential well are investigated. Effects due to the variation of the potential parameters as well as certain results from asymptotic expansions are discussed. ...

Characterizing the Convexity of Joint-Range for a Pair of Inhomogeneous Quadratic Functions and Strong Duality
(2016)
We establish various extensions of the convexity Dines theorem for a (joint-range) pair of inhomogeneous quadratic functions. If convexity fails we describe those rays for which the sum of the joint-range and the ray is ...
Dynamical sampling for shift-preserving operators
(Academic Press Inc Elsevier Science, 2021-03)
In this note, we solve the dynamical sampling problem for a class of shift-preserving operators L:V→V acting on a finitely generated shift-invariant space V. We find conditions on L and a finite set of functions of V so ...
