Changes in blood pressure or flow induce arterial remodeling that normalizes mechanical loads that are imposed on arterial tissue. Arteries are also under substantial longitudinal stretch (axial strain) that may be altered by growth or atrophy of tissues to which they are attached. We therefore tested whether axial strain is also regulated in a negative feedback manner through arterial remodeli...

This paper considers the evolution of smooth, two-dimensional vortices subject to a rotating external strain field, which generates regions of recirculating, cat’s eye stream line topology within a vortex. When the external strain field is smoothly switched off, the cat’s eyes may persist, or they may disappear as the vortex relaxes back to axisymmetry. A numerical study obtains criteria for th...

Adenosine 5'-triphosphate (ATP) synthesis driven by an artificially imposed membrane potential in right-side-out membrane vesicles of Escherichia coli was investigated. Membrane vesicles prepared in the presence of adenosine diphosphate were loaded with K+ by incubation with 0.5 M potassium phosphate. Addition of valinomycin resulted in the synthesis of 0.2 to 0.3 nmol of ATP/mg of membrane pro...

A parametric finite element model of an osteocyte lacuna was developed to predict the microstructural response of the lacuna to imposed macroscopic strains. The model is composed of an osteocyte lacuna, a region of perilacunar tissue, canaliculi, and the surrounding bone tissue. A total of 45 different simulations were modeled with varying canalicular diameters, perilacunar tissue material modu...

By means of ab initio calculations, we study the effect charge transfer and symmetry mismatch on magnetic electronic properties CaMnO3 ultrathin films, epitaxially grown SrTiO3 (001). We find that interplay these degrees freedom, together with low dimensionality strain imposed by substrate, changes bulk occupancy Mn eg orbitals, which determines configuration CMO films. A transition from an ins...

It is now well established that genomic imprinting effects in mammals require a combination of epigenetic modifications imposed during gametogenesis and additional modifications imposed after fertilization. The earliest post-fertilization modifications to be imposed on the genome are those thought to be mediated by factors in the egg cytoplasm. Strain-dependent differences in the actions of the...
