    Notes: Abstract We consider the half-space range-reporting problem: Given a setS ofn points in ℝd, preprocess it into a data structure, so that, given a query half-space γ, allk points ofS ∩ γ can be reported efficiently. We extend previously known static solutions to dynamic ones, supporting insertions and deletions of points ofS. For a given parameterm,n ≤m ≤n ⌊d/2⌋ and an arbitrarily small positive constant ɛ, we achieveO(m 1+ɛ) space and preprocessing time, O((n/m ⌊d/2⌋ logn+k) query time, and O(m1+ɛn) amortized update time (d ≳ 3). We present, among others, the following applications: an O(n1+ɛ)-time algorithm for computing convex layers in ℝ3, and an output sensitive algorithm for computing a level in an arrangements of planes in ℝ3, whose time complexity is O((b+n) nɛ, whereb is the size of the level.

    Notes: Abstract Crystallization kinetics and thermodynamic properties of nucleated isotactic polypropylene (PP) are analyzed using Hoffman—Lauritzen crystallization theory to determine the mechanistic effects of the nucleators. Calorimetric data provides quantitative comparisons between nucleating efficiences of the α (Millad) and β (NJSTAR) nucleator in Metallocene (M) and Ziegler—Natta (ZN) PP. The two types of PP without nucleators showed similar crystallization behavior though the T°m for ZN-iPP was about 10°C higher than M-iPP. Both nucleators show significant improvement in crystallization rate in both types of PP. In addition, Millad outperforms NJSTAR. The magnitude of the kinetic response is,however, different and both the nucleators appear to function better in ZN than in Metallocene PP. β nucleated PP shows predominantly the β form. The amount of the β form is thermal history dependent and changes with supercooling (ΔT=T°m−Tc). Similar equilibrium melting temperature (T°m) in the α nucleated and control PPs indicates the lack of any thermodynamic effect of the α nucleator. All nucleated PPs show a much lower secondary nucleation rate constant, Kg.

    Cellular immune response of patients with uveitis to peptide M, a retinal S-antigen fragment (1993)
    Springer
    Journal of clinical immunology 13 (1993), S. 352-358

    Notes: Abstract Peptide M, an 18-amino acid fragment from position 303 to position 320 of retinal S-antigen, produces experimental autoimmune uveitis (EAU), similar to that produced by native S-antigen, in several vertebrate species including nonhuman primates. It was observed that 12 of the 39 (30.7%) patients with uveitis, 1 of the 29 (3.4%) patients with systemic connective tissue disorders (CTD) without eye involvement, 2 of the 7 (5.8%) patients of CTD with uveitis, 1 of the 17 (5.8%) patients with diabetic retinopathy, and none of the 19 normal healthy controls showed a significant lymphoproliferative response to peptide M (stimulation index of 3 or more). Yeast histone H3 peptide gave a positive response in 1 (2.5%), 2 (6.8%), 1 (14.2%), 2 (11.7%), and 2 (10.5%) individuals, respectively, in the different groups studied. In a few cases a positive response to yeast histone H3 peptide was observed without significant stimulation to peptide M. These findings indicate that peptide M could also be an immunogenic epitope of S-antigen in humans and be aetiopathologically related to uveitis in a subset of patients with this disease. However, unlike experimental animals, the responses to peptide M and yeast histone H3 were nonconcordant, necessitating further studies.
