Measuring the finite width and unitarity corrections to the φω mixing amplitude. Abstract It is shown that the phase of φω interference in the reaction e + e − → π + π − π 0 at energies close to the φ(1020) peak can be calculated in a way that is practically independent of the model of φω mixing. The magnitude of the presently measured interference phase, still of poor accuracy, is in agreement...

Microbiologist, Pacific Southwest Forest and Range Experiment Station, Forest Service, U.S. Department of Agriculture, Riverside, Calif. Abstract: Presently available data indicate that biological dinitrogen fixation is responsible for the greatest proportion of nitrogen entering chaparral ecosystems. Dinitrogen fixation by the Rhizobium-legume symbioses is relatively unimportant in chaparral w...

Abstract: The well known Zarankiewicz’ conjecture is said that the crossing number of the complete bipartite graph Km,n (m ≤ n) is Z(m, n), where Z(m,n) = ⌊ m 2 ⌋⌊ 2 ⌋⌊ 2 ⌋ ⌊ 2 ⌋ (for any real number x, ⌊x⌋ denotes the maximal integer no more than x). Presently, Zarankiewicz’ conjecture is proved true only for the case m ≤ 6. In this article, the authors prove that if Zarankiewicz’ conjecture h...

Received ; accepted – 2 – ABSTRACT Among 330 normal spirals of types Sa-Sc the fraction of objects exhibiting " ring " , " intermediate " and " spiral " arm varieties does not correlated with environment. A similar conclusion appears to apply to the arm varieties of 123 barred spirals of types SBa-SBc. It is concluded that, among the northern Shapley-Ames galaxies, the distinction between the s...

We study the asymptotics in L for complexity penalized least squares regression for the discrete approximation of finite-dimensional signals on continuous domains—e.g., images—by piecewise smooth functions. We introduce a fairly general setting, which comprises most of the presently popular partitions of signal or image domains, like interval, wedgelet or related partitions, as well as Delaunay...

*Erasmus University Rotterdam; presently Visiting Project Associate. I have greatly benefited from the very stimulating research environment and m9-ny helpful discussions at the Institute. b ABSTRACT This paper outlines four existing theories dealing with income distribution and labor market allocation. Predictions on the proper specification of wage equations are derived and testing procedures...

Abstract It has been shown that seventh-order boundary value problem can be transformed into a system of integral equations, which can be solved by variational iteration technique. It is to be mentioned that, presently, the literature on the numerical solutions of seventh order boundary value problems and associated eigen value problems is not available. The approximate results of the equations...
