Homogenous rivers, homogenous faunas [PDF]

open access: yesProceedings of the National Academy of Sciences, 2007
Habitat change and invasions of alien species are usually listed as the two biggest causes of biodiversity loss. When the two coincide, the results can be devastating, because altered habitat often favors alien species adapted to the changed conditions.

Mediated homogenization [PDF]

open access: yesPhysical Review A, 2007
Homogenization protocols model the quantum mechanical evolution of a system to a fixed state independently from its initial configuration by repeatedly coupling it with a collection of identical ancillas. Here we analyze these protocols within the formalism of "relaxing" channels providing an easy to check sufficient condition for homogenization.

On the commutability of homogenization and linearization in finite elasticity [PDF]

open access: yes, 2011
We study non-convex elastic energy functionals associated to (spatially) periodic, frame indifferent energy densities with a single non-degenerate energy well at SO(n).

Functional consequences of the long-term decline of reef-building corals in the Caribbean: evidence of across-reef functional convergence [PDF]

open access: yesRoyal Society Open Science, 2019
Functional integrity on coral reefs is strongly dependent upon coral cover and coral carbonate production rate being sufficient to maintain three-dimensional reef structures.

Modulational stability of cellular flows [PDF]

open access: yes, 2003
We present here the homogenization of the equations for the initial modulational (large-scale) perturbations of stationary solutions of the two-dimensional Navier–Stokes equations with a time-independent periodic rapidly oscillating forcing.

Homogeneous algebras

open access: yesJournal of Algebra, 2003
Various concepts associated with quadratic algebras admit natural generalizations when the quadratic algebras are replaced by graded algebras which are finitely generated in degree 1 with homogeneous relations of degree N. Such algebras are referred to as {\sl homogeneous algebras of degree N}.

Homogeneity Pursuit [PDF]

open access: yesJournal of the American Statistical Association, 2015
This paper explores the homogeneity of coefficients in high-dimensional regression, which extends the sparsity concept and is more general and suitable for many applications. Homogeneity arises when regression coefficients corresponding to neighboring geographical regions or a similar cluster of covariates are expected to be approximately the same ...

“Homogenization with non‐homogeneous plastic flow”

open access: yesInternational Journal for Numerical and Analytical Methods in Geomechanics, 2023
AbstractThis paper provides the solution of a homogenization model that simultaneously considers the plastic and elastic strain fields in a single analytical formulation. In addition, the authors aim to decouple plastic flows triggered in the inclusions, in the matrix at the interfaces with the inclusions, and in the matrix at a large distance from the

Bayesian Numerical Homogenization [PDF]

open access: yes, 2014
Numerical homogenization, i.e. the finite-dimensional approximation of solution spaces of PDEs with arbitrary rough coefficients, requires the identification of accurate basis elements.
