Native defects in hybrid C/BN nanostructures [PDF]
, 2011 First-principles calculations of substitutional defects and vacancies are performed for zigzag-edged hybrid C/BN nanosheets and nanotubes which recently have been proposed to exhibit half-metallic properties. The formation energies show that defects form

Cathodoluminescence of oval defects in GaAs/AlxGa1–xAs epilayers using an optical fiber light collection system [PDF]
, 1988 A cathodoluminescence system using a novel optical fiber light collection system is employed to study oval defects in GaAs/Alx Ga1–x As epilayers grown by molecular beam epitaxy.

Physical Review D, 1992 I analyze the interplay of gauge and global symmetries in the theory of topological defects. In a two-dimensional model in which both gauge symmetries and {\it exact} global symmetries are spontaneously broken, stable vortices may fail to exist even though magnetic flux is topologically conserved.

Surface defects and temperature on atomic friction [PDF]
, 2011 We present a theoretical study of the effect of surface defects on atomic friction in the stick-slip dynamical regime of a minimalistic model. We focus on how the presence of defects and temperature change the average properties of the system.

Physical Review D, 2002 We introduce a method to obtain deformed defects starting from a given scalar field theory which possesses defect solutions. The procedure allows the construction of infinitely many new theories that support defect solutions, analytically expressed in terms of the defects of the original theory. The method is general, valid for both topological and non-

MEF2C regulates outflow tract alignment and transcriptional control of Tdgf1 [PDF]
, 2016 Congenital heart defects are the most common birth defects in humans, and those that affect the proper alignment of the outflow tracts and septation of the ventricles are a highly significant cause of morbidity and mortality in infants.

Scalar fields: from domain walls to nanotubes and fulerenes [PDF]
, 2002 In this work we review some features of topological defects in field theory models for real scalar fields. We investigate topological defects in models involving one and two or more real scalar fields.
