Persistence in fluctuating environments [PDF]

open access: yes, 2010
Understanding under what conditions interacting populations, whether they be plants, animals, or viral particles, coexist is a question of theoretical and practical importance in population biology. Both biotic interactions and environmental fluctuations

On the Coexistence of Banks and Markets* [PDF]

open access: yesThe Scandinavian Journal of Economics, 2007
AbstractWe examine the coexistence of banks and financial markets by studying a credit market where the qualities of investment projects are not observable and the investment decisions of entrepreneurs are not contractible. Standard banks can alleviate moral‐hazard problems, while financial markets operated by investment banks can alleviate adverse ...

Coexistence in interval effect algebras [PDF]

open access: yes, 2010
Motivated by the notion of coexistence of effect-valued observables, we give a characterization of coexistent subsets of interval effect ...

Piccoli gesti, piccole cose. Abitare, navigare, farsi comunità a bordo della barca a vela Raj

open access: yesArchivio Antropologico Mediterraneo, 2023
Considering the Raj as a social unit, the present contribution reflects upon the constituent relation between the materiality/spatiality of the sailboat, and the multiple processes of subjectification of the hermenautic crew.

Effect of migration in a diffusion model for template coexistence in protocells [PDF]

open access: yes, 2014
The compartmentalization of distinct templates in protocells and the exchange of templates between them (migration) are key elements of a modern scenario for prebiotic evolution.

Phase behaviour of binary mixtures of diamagnetic colloidal platelets in an external magnetic field

open access: yes, 2011
Using fundamental measure density functional theory we investigate paranematic-nematic and nematic-nematic phase coexistence in binary mixtures of circular platelets with vanishing thicknesses.

Thin-thick coexistence behavior of 8CB liquid crystalline films on silicon

open access: yes, 2008
The wetting behavior of thin films of 4'-n-octyl-4-cyanobiphenyl (8CB) on Si is investigated via optical and x-ray reflectivity measurement. An experimental phase diagram is obtained showing a broad thick-thin coexistence region spanning the bulk ...

Liquid-liquid equilibrium for monodisperse spherical particles

open access: yes, 2001
A system of identical particles interacting through an isotropic potential that allows for two preferred interparticle distances is numerically studied.

Controlling crystal symmetries in phase-field crystal models

open access: yes, 2010
We investigate the possibility to control the symmetry of ordered states in phase-field crystal models by tuning nonlinear resonances. In two dimensions, we find that a state of square symmetry as well as coexistence between squares and hexagons can be ...
