The seasons associated with laboratory isolation of respiratory syncytial virus (RSV) (for 1981-2004) and RSV-related emergency department admissions (for 1990-2004) ended 3.1 and 2.5 weeks earlier, respectively, per 1 degrees C increase in annual central England temperature (P=.002 and .043, respectively). Climate change may be shortening the RSV season.

We study the Minkowski length L(P ) of a lattice polytope P , which is defined to be the largest number of non-trivial primitive segments whose Minkowski sum lies in P . The Minkowski length represents the largest possible number of factors in a factorization of polynomials with exponent vectors in P , and shows up in lower bounds for the minimum distance of toric codes. In this paper we give a...

A total of 78 orthodontic patients participated in a study of the degree of decalcification inhibition induced by daily treatment with 0.4% SnF2 gel. Control patients (n = 39) were managed exactly as were the test patients (n = 39) except that the latter were instructed to brush at bedtime each day with the gel. In the nongel users, 24 (64.1%) developed decalcification after 18-24 months bandin...
