Theoretical/computational methods have been extensively applied to screen possible nano-structures attempting to maximize catalytic and stability properties for applications in electrochemical devices. This work shows that the method used to model core@shell structures is of fundamental importance in order to truly represent the physicochemical changes arising from the formation of a core-shell...

Abstract We studied the dynamics of surfacea and wake charges induced by a charged particle traversing a dielectric slab. It is shown that after the crossing of the slab first boundary, the induced on the slab surface charge (image charge) is transformed into the wake charge, which overflows to the second boundary when the particle crosses it. It is also shown, that the polarization of the slab...

[1] Subduction zone seismicity is highly variable. Great earthquakes occur at few subduction zones around the world, with significant variation in size and frequency of deep events. Interactions between overriding and subducting plates and slab pull strength for individual plates provide a framework for understanding these variations. Previous work suggests an inverse correlation between great ...

in this paper, evaluation of torsional stiffness in beam and slab bridge deck elements is presented. a beam and slab bridge decks structurally behave as a grillage. a grillage has an efficient transverse load distribution due to transverse asymmetric load. in the case of bridge deck without transverse beams in the span, transverse load distribution depends on the torsional stiffness of longitud...

Let P be a point set of n points in R. Every point has a label/color (say black or white), but we do not know the labels. In particular, let B and W be the set of black and white points in P . Furthermore, let ∆ = diam(P ), and assume that there exist two parallel hyperplanes h, h′ in distance γ from each other, such that the slab between h and h′ does not contain an point of P , and the points...

The Laramide orogeny is the Late Cretaceous to Palaeocene (80^55 Ma) orogenic event that gave rise to the Rocky Mountain fold and thrust belt in Canada, the Laramide block uplifts in the USA, and the Sierra Madre Oriental fold and thrust belt in Mexico. The leading model for driving Laramide orogenesis in the USA is flat-slab subduction, whereby stress coupling of a subhorizontal oceanic slab t...

A multigrid method for solving the 1-D slab-geometry S N equations with isotropic scattering and absorption is presented. The case with no absorption was treated in part I of this paper 10]. Relaxation is based on a two-cell inversion, which is very eecient because it takes advantage of the structure of the two-cell problem. For interpolation we use kinked linear elements. The kink is based on ...
