Despite the incorrect asymptotic behavior of its potential, the time-dependent local density approximation can yield accurate optical spectra. The oscillator strengths of Rydberg excitations appear in the calculated spectrum as continuum contributions with excellent optical intensity. We explain why, illustrate this for the neon and helium atoms, and also discuss when such calculations of the o...

Second-order [ O(k(2)), k = omega/c] nondipole effects in soft-x-ray photoemission are demonstrated via an experimental and a theoretical study of angular distributions of neon valence photoelectrons in the 100-1200 eV photon-energy range. A newly derived theoretical expression for nondipolar angular distributions characterizes the second-order effects using four new parameters with primary con...

intravenous laser blood irradiation was first introduced into therapy by the soviet scientists en.meschalkin and vs.sergiewski in 1981. originally this method was developed for the treatment of cardiovascular diseases. improvement of rheologic properties of the blood as well as improvement of microcirculation and reduction of the area of infarction has been proved. further, reduction of dysrhyt...

We report quantum Monte Carlo QMC , plane-wave density-functional theory DFT , and interatomic pair-potential calculations of the zero-temperature equation of state EOS of solid neon. We find that the DFT EOS depends strongly on the choice of exchange-correlation functional, whereas the QMC EOS is extremely close to both the experimental EOS and the EOS obtained using the best semiempirical pai...

A Cylindrocarpon species with up to 10 microm wide, straight and predominantly 3-septate macroconidia, subglobose to ovoidal microconidia and chlamydospores, is described as Cyl. pauciseptatum. It is most similar to Cyl. austrodestructans but no chlamydospores and microconidia are formed in the latter. Similar macroconidia also occur in Cyl. theobromicola, which forms oval to ellipsoidal microc...

We present a new determination of the metallicity gradient in M33, based on Keck/LRIS measurements of oxygen abundances using the temperature-sensitive emission line [O III] λ4363 Å in 61 H II regions. These data approximately triple the sample of direct oxygen abundances in M33. We find a central abundance of 12 + log(O/H) = 8.36±0.04 and a slope of −0.027±0.012 dex kpc−1, in agreement with in...

Edge-localized modes (ELMs) and disruptions remain a major concern to divertor plasma-facing components (PFCs) during normal and abnormal operation of future tokamaks. Of particular concern are the pulses of energy and particles that are transported during ELMs to the divertor surface. ELMs, therefore, can result in excessive divertor erosion and plasma contamination. A two-fluid model is enhan...
