Vlasov Simulations of Thermal Plasma Waves
... To perform the same calculation on a regular grid in the boosted frame, we must use the grid shown in the right hand panel of Fig. 1 as red dash-dot lines. If we additionally used a rectangular boundary, it would need to encompass the whole region including parts outside of the the domain of interes ...

... is the volume enclosed between the plane y A (S × {0}) and the deformed lower surface of the film y(S×{0}) where y A (x) := Ax and A is a constant 3 × 3 matrix (see Ref. 12)) for the detailed discussion). Note that if the film is not stretched as deposited, A = I where I is the identity matrix. The ...

WO3 nanosponge photoanodes with high applied
... Fig. 2a shows photographs of the WO3 nanoparticle dispersions. Dispersion D2, used to fabricate photoanode W2, was beige, and the dispersed nanoparticle size was evaluated by using a particle size analyzer to be mainly 264.1 nm in the range of 250–400 nm (Fig. 2b). This value indicates that the nano ...

Density of states
.svg?width=300)
In solid-state and condensed matter physics, the density of states (DOS) of a system describes the number of states per interval of energy at each energy level that are available to be occupied. Unlike isolated systems, like atoms or molecules in gas phase, the density distributions are not discrete like a spectral density but continuous. A high DOS at a specific energy level means that there are many states available for occupation. A DOS of zero means that no states can be occupied at that energy level. In general a DOS is an average over the space and time domains occupied by the system. Localvariations, most often due to distortions of the original system, are often called local density of states (LDOS). If the DOS of an undisturbedsystem is zero, the LDOS can locally be non-zero due to the presence of a local potential.
