Competing activation mechanisms in epidemics on networks
(2012-04-20)
Article
Accés restringit per política de l'editorialIn contrast to previous common wisdom that epidemic activity in heterogeneous networks is dominated by the hubs with the largest number of connections, recent research has pointed out the role that the innermost, dense ... -
Computational fluid dynamics modeling of impinging gas-jet systems: II. Application to an industrial cooling system device
(2005-07-15)
Article
Accés restringit per política de l'editorialA numerical analysis of the flow behavior in industrial cooling systems based on arrays of impinging jets has been performed, using several eddy viscosity models to determine their modeling capabilities. For the cooling ... -
Computer simulation study of ion-water and water-water hydrogen bonds in sulfuric acid solutions at low temperatures
(2022-02-01)
Article
Accés obertMolecular dynamics simulations of sulfuric acid solutions at several temperatures (230, 250, 273 and 298 K) and concentrations (10, 20, 30 and 40 wt%) have been carried out. The dissociation of the acid has been explicitly ... -
Conformational diversity in contryphans from conus venom: Cis-trans isomerisation and aromatic/proline interactions in the 23-membered ring of a 7-residue peptide disulfide loop
(2013-11-05)
Article
Accés restringit per política de l'editorialConformational diversity or “shapeshifting” in cyclic peptide natu- ral products can, in principle, confer a single molecular entity with the proper- ty of binding to multiple receptors. Conformational equilibria have ... -
Convergence to steady-state and boundary layer profiles in a linear chromatography system
(2015-01-01)
Article
Accés restringit per política de l'editorialWe study the hyperbolic system of equations of the so-called linear transport model in a true moving bed chromatography device with four ports. By using methods based on a suitable energy functional we show that all solutions ... -
