We study the structure of planar point sets that determine a small number of distinct distances. Specifically, we show that if a set P of n points determines o(n) distinct distances, then no line contains Ω(n) points of P and no circle contains Ω(n) points of P . We rely on the bipartite and partial variant of the Elekes-Sharir framework that was presented by Sharir, Sheffer, and Solymosi in [2...

We have surveyed 401 color selected IRAS sources in the Galactic disk in the SiO J = 1–0 v = 1 and 2 maser lines at 43 GHz, resulting in 254 (239 new) detections. The observed sources lie mostly in a strip of the inner Galactic disk with boundaries −10 < l < 40 and |b|< 3. This survey provides radial velocities of inner-disk stars for which optical measurements cannot be made due to interstella...

A range is defined as the length between two residues along a given sequence, i.e., a range is defined as M = 1 when 1 ≦ k≦ 8 where k = |i-j| and i and j are the residues numbers along the sequence. In the same way, 9 ≦ k ≦ 20, 21 ≦ k ≦ 30, 31 ≦ k ≦ 40 and so on define respective ranges M = 2, 3, 4 ···. The average distances between C atoms of residues were calculated in each range using protei...

Employing five commuting sets of five-qubit observables, we propose specific 160−661 and 160−21 state proofs of the Bell-Kochen-Specker theorem that are also proofs of Bell’s theorem. A histogram of the ‘Hilbert-Schmidt’ distances between the corresponding maximal bases shows in both cases a noise-like behaviour. The five commuting sets are also ascribed a finite-geometrical meaning in terms of...

We previously reported an association between elevated serum antibody titers to the 90-kDa human heat shock protein (Hsp90), periodontal health and colonization by Porphyromonas gingivalis. In this study, we examined the cellular localization of the Hsp90 homologue of P. gingivalis. Cultures of P. gingivalis were heat-stressed (45 degrees C) and examined for localization of the Hsp90 homologue....

In the title compound, C(22)H(21)ClN(4)O(2)S, the bicyclic triazolopyrimidine ring system is nearly planar, and oriented at dihedral angles of 89.45 (3)° with respect to the chlorobenzene ring and 87.03 (3)° with respect to the terminal phenyl ring. In the crystal structure, mol-ecules are linked by π-π stacking inter-actions between the triazolopyrimidine rings [centroid-centroid distances of ...

p. 14679, l. 21: The reviewer is right by stating that a diagnostic treatment of snow is especially worrisome because of lower fall speed of snow and of the larger distances from the cloud to the surface. We are aware of that and the extension of the prognostic treatment to snow is work in progress. But as the current study focuses on warm rain processes and the effect of Giant CCN (like sea sa...

In the title compound, C(14)H(21)NO(4)S, the O-S-O angle is 120.06 (11)°, with the S atom adopting a distorted tetra-hedral geometry. In the crystal, N-H⋯O hydrogen bonds connect the mol-ecules along the a axis, generating an infinite chain. The disordered C atoms of the isobutyl group were refined with the C-C distances restrained to 1.52 (1) Å and the occupancy ratio refined to 0.504 (3):0.49...

Introduction: The age of peak freestyle swimming speed was reported to be at ~17 years for women and ~19 years for men. However, the age of peak swimming speed for other strokes such as butterfly is not known. Objectives: We investigated whether the age of peak swimming speed and peak swimming speed changed across years in elite butterfly and freestyle swimmers at national level (Switzerland) b...
