Reappearance of symptoms of cranial nerve dysfunction is not uncommon after successful microvascular decompression (MVD). The purpose of this study was to report two quite unusual cases of recurrent and newly developed hemifacial spasm (HFS) caused by a new conflicting artery more than 20 years after the first successful surgery. In Case 1, the first MVD was performed for HFS caused by the post...
This article addresses the problem of manipulation planning in the presence of uncertainty. We begin by reviewing the worst-case planning techniques introduced by Lozano-Pérez et al. (1984) and show that these methods are limited by an information gap inherent to worst-case analysis techniques. As the task uncertainty increases, these methods fail to produce useful information, even thou...
In the first part of the review we expound m detail the umfied theory of weak and electromagnetic interactions of Glashow, Wemberg and Salam In the second part, on the basms of this theory a number of the neutral current induced processes are &scussed We consider in detail the deep inelastic scattermg of neutnnos on nucleons, the P-odd asymmetry m the deep inelastic scattering of longitudinally...
The famous circular law asserts that if Mn is an n×n matrix with iid complex entries of mean zero and unit variance, then the empirical spectral distribution (ESD) of the normalized matrix 1 √ n Mn converges both in probability and almost surely to the uniform distribution on the unit disk {z ∈ C : |z| ≤ 1}. After a long sequence of partial results that verified this law under additional assump...

The clinical heterogeneity among first relapses of childhood ETV6/RUNX1-positive acute lymphoblastic leukemia indicates that further genetic alterations in leukemic cells might affect the course of salvage therapy and be of prognostic relevance. To assess the incidence and prognostic relevance of additional copy number alterations at relapse of the disease, we performed whole genome array compa...
A method is presented for calculating the real part of the longitudinal impedance for both a small hole and a long slot in a beam vacuum chamber with a circular cross section. The length of the slot can be arbitrarily large, the only requirement on the dimensions of the slots is that its width be much smaller than c/w. Regular . arrays of N slots periodically distributed along the pipe are also...

Lutetium oxyorthosilicate Lu2( S iO4)O has two crystallographically independent lutetium sites. When it is doped with Ce, the dopant Ce is assumed to occupy two different sites and thus the existence of two activation centers (called “Cel” and “Ce2”) was proposed. UV and gamma-ray excited spectra clearly indicate that two activation centers exist in cerium-doped lutetium oxyorthosilicate Lu2(Si...
