We consider a model of shape memory materials in which hierarchical twinning near the habit plane (austenite-martensite interface) is a new and crucial ingredient. The model includes (1) a triple-well potential (4' model) in local shear strain, (2) strain gradient terms up to second order in strain and fourth order in gradient, and (3) all symmetry allowed compositional fluctuationinduced strai...

Background. Rural residents seeking health care face barriers due to a shortage of healthcare professionals and the travel distance required to obtain medical services. This can lead to potentially harmful health outcomes, particularly when these citizens are unable to access specialized medical care. Few studies have specifically evaluated rural residents’ ability to access medical specialists...

The spontaneous fibrinolytic activity of blood is due to a labile activator which appears to be stabilized by adsorption to fibrin (Fearnley and Tweed, 1953; Fearnley, 1953; Flute, 1960). At present activator activity can be measured only indirectly through its conversion of plasminogen to plasmin which in turn causes fibrinolysis. Whatever method is used it is essential to cool the blood sampl...
