Recently, moiré superlattices have been found on the surface of topological insulators due to rotational misalignment topmost layers. In this work, we study effects states using a continuum model Dirac electrons moving in periodic potential. Unlike twisted bilayer graphene, cannot host isolated bands their nature. Instead, find (high-order) van Hove singularities (VHS) band structure that give ...

The occlusion derived form of baculovirus is specially adapted for primary infection of the host midgut epithelium. As such, the virion must contain the proteins essential for host range determination and initiation of infection. Because knowledge of virion composition is a prerequisite for functional investigation, this study used a combination of techniques to identify the proteins present wi...

Understanding virus evolution is key for improving ways to counteract virus-borne diseases. Results from comparative analyses have previously suggested a trade-off between fecundity and lifespan for viruses that infect the bacterium Escherichia coli (i.e. for coliphages), which, if confirmed, would define a particular constraint on the evolution of virus fecundity. Here, the occurrence of such ...

• Arrest radius of a hydraulic fracture after injection shut-in. Numerical delineation boundary for immediate arrest upon quantification the amount post-injection propagation. Semi-analytical solution pulse in viscosity regime. We investigate propagation and radial end injection. Depending on regime at time shut-in injection, excess elastic energy may be stored surrounding medium. Once has stop...

Adult neurogenesis has been the focus of intense investigation, but the function of new neurons remains elusive. Snyder et al. (2011) report that new neurons in the hippocampus play an important role in appropriate shut-off of the stress response.

The baculovirus is a classic example of a parasite that alters the behavior or physiology of its host so that progeny transmission is maximized. Baculoviruses do this by inducing enhanced locomotory activity (ELA) that causes the host caterpillars to climb to the upper foliage of plants. We previously reported that this behavior is not induced in silkworms that are infected with a mutant baculo...
