The state of stress in the lithosphere provides strong constraints on the forces acting on the
plates. The directions of principal stresses in the plates as indicated by midplate earthquake …

Torque poles are calculated for a variety of possible forces acting on the plates, including
ridge push, slab pull, and collisional resistance. These torque poles are then compared to the …

The liquid-crystal dimer 1′′, 7′′-bis (4-cyanobiphenyl-4′-yl) heptane (CB7CB)
exhibits two liquid-crystalline mesophases on cooling from the isotropic phase. The high-…

Non-spherical nanostructures derived from soft matter and with uniform size—that is,
monodisperse materials—are of particular utility and interest, but are very rare outside the …

Recent advances in multi-electrode array technology have made it possible to monitor large
neuronal ensembles at cellular resolution in animal models. In humans, however, current …

G protein-coupled receptors (GPCRs) are classically characterized as cell-surface receptors
transmitting extracellular signals into cells. Here we show that central components of a …

The use of specular neutron reflection to study a wide variety of problems in surface and
interfacial chemistry is introduced and discussed. Recent developments in neutron reflectometry …

Lymphocyte chemotaxis is a complex process by which cells move within tissues and across
barriers such as vascular endothelium and is usually stimulated by chemokines such as …

Members of the chemokine receptor family CCR5 and CXCR4 have recently been shown to
be involved in the entry of human immunodeficiency virus (HIV) into target cells. Here, we …

Leukocytes participate in host defense by accumulating at local sites in response to inflammatory
mediators where they may engulf foreign material and/or release toxic products that …
