Non-linear spin to charge conversion in mesoscopic structures [PDF]
, 2011 Motivated by recent experiments [Vera-Marun et al., arXiv:1109.5969], we formulate a non-linear theory of spin transport in quantum coherent conductors.

Modulation of apical constriction by Wnt signaling is required for lung epithelial shape transition
Development, 2017 In lung development, the apically constricted columnar epithelium forms numerous buds during the pseudoglandular stage. Subsequently, these epithelial cells change shape into the flat or cuboidal pneumocytes that form the air sacs during the canalicular ...

3D Mechanical Confinement Directs Muscle Stem Cell Fate and Function
Advanced Biology, EarlyView.This study reveals that the physical environment surrounding muscle stem cells (MuSCs) plays a crucial role in their function. Using a 3D hydrogel system, it shows that increased confinement preserves MuSC stemness by limiting activation, proliferation, and differentiation.

Gender and Racial Disparities in Life-Space Constriction Among Older Adults.
The gerontologist, 2016 PURPOSE OF THE STUDY "Life-space" is the spatial area through which a person experiences and interacts with the world. Life-space constriction, the shrinking of the spatial area that a person traverses, is associated with negative health outcomes in ...

Advanced Engineering Materials, EarlyView.Integrity constraints enforce consistency and completeness on data. The article discusses a newly developed validator for checking integrity constraints in Shapes Constraint Language (SHACL) through reduction to SPARQL Protocol and RDF Query Language (SPARQL) queries. It can be used with systems for ontology‐based database access.

Magnetic domain walls in constrained geometries
, 2004 Magnetic domain walls have been studied in micrometer-sized Fe20Ni80 elements containing geometrical constrictions by spin-polarized scanning electron microscopy and numerical simulations. By controlling the constriction dimensions, the wall width can be

Self-consistent Hartree theory of the role of electron-electron interactions in the electronic structure and conductance quantization of graphene nanoconstrictions [PDF]
arXiv, 2012 We present self-consistent calculations of electron transport in graphene nanoconstrictions within the Hartree approximation. We consider suspended armchair ribbons with V-shaped constrictions having perfect armchair or zigzag edges as well as mesoscopically smooth but atomically stepped constrictions with cosine profiles. Our calculations are based on

Tuberculous constrictive pericarditis
Research in Cardiovascular Medicine, 2015 INTRODUCTION: Constrictive pericarditis is characterized by constriction of the heart secondary to pericardial inflammation. Cardiovascular magnetic resonance (CMR) imaging is useful imaging modality for addressing the challenges of confirming this diagnosis.
