Single-crystalline cobalt silicide/SiO(x) nanocables have been grown on Co thin films on an SiO(2) layer by a self-catalysis process via vapor-liquid-solid mechanism. The nanocables consist of a core of CoSi nanowires and a silicon oxide shell with a length of several tens of micrometers. In the confined space in the oxide shell, the CoSi phase is stable and free from agglomeration in samples a...

tor even if it’s walking toward you up the street, assuming you could see it, of course. The gate length—the marker for gauging how small that CMOS transistor is—will be roughly one-fifth the size of the smallest in production today, only 10 nm instead of today’s 50 nm. To get to that size and ensure that the transistor still operates will require many changes: • To improve performance, silicon...

The liver is an organ that performs a lot of important functions in the body. However, if you observe it under the microscope, it seems to be very quiet because most of its cells remain in a non-dividing state (this is called quiescent). The liver is so important that it is provided with a great ability to tolerate several kinds of injuries. After a wound or other damage, all the cells in the l...

Let G be a simple algebraic group defined over an algebraically closed field k of characteristic zero. Write g for its Lie algebra. Let x ∈ g be a nilpotent element and G·x ⊂ g the corresponding nilpotent orbit. The maximal number m such that (adx) 6= 0 is called the height of x or of G·x, denoted ht(x). Recall that an irreducible G-variety X is called G-spherical if a Borel subgroup of G has a...
