A unification of the gravitational with the electromagnetic interaction within a classical framework is proposed. It is based on a Fs-geometry, with x^ — qjm. The sole source term is mechanical stress energy, positioned along X5. The trajectories of testbodies are placed in V4 (xo = const)-slices. The final field equation couples a geometric G-tensor to mechanical stress energy, its momentum wi...

The elastic properties of DNA are essential for its biological function. They control its bending and twisting as well as the induction of structural modifications in the molecule. These can affect its interaction with the cell machinery. The response of a single DNA molecule to a mechanical stress can be precisely determined in single-molecule experiments which give access to an accurate measu...

In this study the behavioral effects of sectioning the saphenous nerve at the time of application of the loose ligature and the effect of a selective ?1-adrenergic antagonist for two weeks after tying ligatures was examined. Male Sprague-Dawley rats were used in this study. Animals were divided into six groups: Sham-operated, sciatic nerve ligation (CCI), saphenous nerve section (Saph), CCI + S...

Mechanical interaction of cells and their surroundings are prominent in mechanically active tissues such as cartilage. Chondrocytes regulate their growth, matrix synthesis, metabolism, and differentiation in response to mechanical loadings. Cells sense and respond to applied physical forces through mechanosensors such as integrin receptors. Herein, we examine the role of mechanical stimulation ...

The dimensions of microbumps in three-dimensional integration reach microscopic scales and thus necessitate a study of the multiscale microstructures in microbumps. Here, we present simulated mesoscale and atomic-scale microstructures of microbumps using phase field and phase field crystal models. Coupled microstructure, mechanical stress, and electromigration modeling was performed to highligh...
