We examine the surface morphological evolution of a conducting crystalline solid under the simultaneous action of an electric field and mechanical stress based on a fully nonlinear model and combining linear stability theory with self-consistent dynamical simulations. We demonstrate that electric current, through surface electromigration, can stabilize the surface morphology of the stressed sol...

The acetylene-oxygen combustion flame technique was applied to the homoepitaxial deposition of diamond single crystals on cylindrically shaped {111}, {001} and {110} type IIa natural diamond substrates. After deposition the specimen revealed surface stabilization phenomena like flat facets and curved bands for orientations corresponding to Miller indices {hhk}h < k in the (110) zones. The surfa...

OBJECTIVE Safe articular cartilage lesion stabilization is an important early surgical intervention advance toward mitigating articular cartilage disease burden. While short-term chondrocyte viability and chondrosupportive matrix modification have been demonstrated within tissue contiguous to targeted removal of damaged articular cartilage, longer term tissue responses require evaluation to fur...

This paper considers the quadratic stabilization problem of multi-input planar switched systems. Based on some basic lemmas, some uniformly quadratic stabilization criteria are established. Furthermore, an example is given to illustrate our results in this

We determined the added enthalpic and entropic contributions of protective osmolytes to the folding of a model peptide into its native beta-hairpin state. In contrast to entropically driven steric "crowding", this study shows that sugars and polyols can act as protective osmolytes by primarily diminishing the unfavourable enthalpic contribution to folding.

We review the mechanism of gaugino condensation in the framework of the d = 10 heterotic string and its d = 11 extension of Horava and Witten. In particular we emphasize the relation between the gaugino condensate and the flux of the antisymmetric tensor fields of higher dimensional supergravity. Its potential role for supersymmetry breakdown and moduli stabilization is investigated.

Let G be the group of projectivities stabilizing a unital U in PG(2, q2) and let A,B be two distinct points of U . In this paper we prove that, if G has an elation group of order q with center A and a group of projectivities stabilizing both A and B of order a divisor of q − 1 greater than 2(√q − 1), then U is an ovoidal Buekenhout–Metz unital. From this result two group theoretic characterizat...
