ISSN: 1476-4687Source: Nature Archives 1869 - 2009Topics: BiologyChemistry and PharmacologyMedicineNatural Sciences in GeneralPhysicsNotes: [Auszug] In these investigations a charge is put on the polymer surface by heating in contact with a metal surface at the softening point of the polymer and then applying a static pressure which just deforms the polymer. This process is considered to be the most promising for investigation because the ...Type of Medium: Electronic ResourceURL: -

ISSN: 1436-4646Keywords: Global optimization ; Discrete optimization ; Algorithm complexity ; Random search ; Markov chainsSource: Springer Online Journal Archives 1860-2000Topics: Computer ScienceMathematicsNotes: Abstract Pure Adaptive Search is a stochastic algorithm which has been analyzed for continuous global optimization. When a uniform distribution is used in PAS, it has been shown to have complexity which is linear in dimension. We define strong and weak variations of PAS in the setting of finite global optimization and prove analogous results. In particular, for then-dimensional lattice {1,⋯,k} n , the expected number of iterations to find the global optimum is linear inn. Many discrete combinatorial optimization problems, although having intractably large domains, have quite small ranges. The strong version of PAS for all problems, and the weak version of PAS for a limited class of problems, has complexity the order of the size of the range.Type of Medium: Electronic ResourceURL: -

If we edit the sites so that only the parsimony sites (phylogenetically informative sites) are present, then c will denote the length of these (edited) sequences. Let T,, T2 and T3 be ...Type of Medium: Electronic ResourceURL: -

Diamond1 is correct in identifying 'convergence' as one of the important features for tree reconstruction á€" the tree should not change as more data are collected.

ISSN: 0021-8995Keywords: Chemistry ; Polymer and Materials ScienceSource: Wiley InterScience Backfile Collection 1832-2000Topics: Chemistry and PharmacologyMechanical Engineering, Materials Science, Production Engineering, Mining and Metallurgy, Traffic Engineering, Precision MechanicsPhysicsNotes: A Sward rocker tester is used to obtain the Sward number for glass, mild steel, copper, poly(methyl methacrylate), polyethylene of various densities, and natural rubber. A relationship between the number and mechnical properties is investigated. It is shown that with metals and glass the number is essentially a frictional factor. With plastics and rubber it is a true hardness factor, involving dynamic Young's modulus, Poisson's ratio, and damping capacity. The aim of the investigation is to encourage the development of the Sward test as a nondestructive quality test for plastics.Additional Material: 2 Ill.Type of Medium: Electronic ResourceURL: -

An analysis of the data suggested that a significant proportion of the bulk water in nuclear and cortical lens tissue may behave differently to pure water. In addition, the Maxwell-Fricke mixture theory was used to estimate the amount of hydrated water that relaxes far below 1 GHz.Additional Material: 4 Ill.Type of Medium: Electronic ResourceURL: -

The results show a variation with age of the dielectric properties of brain. An analysis of the data suggests that the water dispersion in the brain of newly born animals can be represented by a Debye equation. This dispersion increases in complexity with age, and there is evidence of a smaller additional relaxation process centered around 1 GHz. It is concluded that the principal contribution to this subsidiary dispersion region arises from water of hydration.Additional Material: 3 Ill.Type of Medium: Electronic ResourceURL:
