The term pseudotumour of the orbit is unfortunate, since it merely purports to describe a negative quality of a considerable number of diverse pathological conditions. Among ophthalmologists it is common practice to limit the term to those lesions which are of an idiopathic inflammatory nature (Blodi and Gass, 1967), whereas Birch-Hirschfeld, who introduced the term, included all non-neoplastic...
For a (connected) smooth projective curve C over the rational numbers Q, it is known that the rational points CpQq depends on the genus g “ gpCq of C: (1) If g “ 0, then the local-global principle holds for C, i.e.: CpQq ‰ H if and only if CpQpq ‰ H for all primes p ď 8 (we understand Qp “ R when p “ 8). In other words, C is globally solvable if and only if it is locally solvable everywhere. An...
ASTRONOMY AND ASTROPHYSICS First evidence of the nite horizontal extent of the optical turbulence layers. Implications for the new adaptive optics techniques. Abstract. It was recently shown (Masciadri et al. 2000, Masciadri 2001a), using a numerical simulation (Meso-Nh model), that the hypothesis of considering horizontally uniform C 2 N can have severe consequences. For example, the integrati...
Precise measurement of a stress-free reference lattice parameter is vital in the determination of residual stress by diffraction techniques using /2-based analyses. For the evaluation of the residual strain profile in fusion-welded material, it is particularly important to correct the measured strain point-by-point by a stress-free reference for each spatial location across the weld. This is ...
A well-written research article is quintessential for the innovative work to be appreciated and receiving a good number of citations. But writing a good research article is not an art. With due care and understanding the focus requirements can help a researcher to present his work with high scientific impact. The seeds of a research article are in the primary research or discovery by a research...
In recent years, there has been an increasing interest in planted (l, d) motif search (PMS) with applications to discovering significant segments in biological sequences. However, there has been little discussion about PMS over large alphabets. This paper focuses on motif stem search (MSS), which is recently introduced to search motifs on large-alphabet inputs. A motif stem is an l-length strin...
Facets for the polyhedron of two-connected networks with bounded rings Abstract. We study the polyhedron associated with a network design problem which consists in determining at minimum cost a two-connected network such that the shortest cycle to which each edge belongs (a \ring") does not exceed a given length K. We present here a new formulation of the problem and derive facet results for di...
The decay J/ψ → ωpp̄ is studied using a 5.8 × 10 J/ψ event sample accumulated with the BES II detector at the Beijing electron-positron collider. The decay branching fraction is measured to be B(J/ψ → ωpp̄) = (9.8 ± 0.3 ± 1.4) × 10. No significant enhancement near the pp̄ mass threshold is observed, and an upper limit of B(J/ψ → ωX(1860))B(X(1860) → pp̄)< 1.5 × 10 is determined at the 95% confidenc...
