The QCD sum rule for the correlator of topological charge densities χ(Q2) and related to it longitudinal part of the correlator of singlet axial currents is considered in the framework of instanton model. The coupling constant fη′ of η -meson with the singlet axial current is determined. Its value appears to be in a good coincidence with the value determined recently from the connection of the ...
This paper introduces a new algorithm, Q2, for optimizing the expected output of a multiinput noisy continuous function. Q2 is designed to need only a few experiments, it avoids strong assumptions on the form of the function, and it is autonomous in that it requires little problem-speci c tweaking. These capabilities are directly applicable to industrial processes, and may become increasingly v...
In this article, the Hall planes of even order q2 arc characterized as translation planes of even order q2 admitting a Baer group of order q and at least q+l nontrivial elations.
The notion of m-regular system on the Hermitian variety H(n, q2) was introduced by B. Segre (Ann. Math. Pura Appl. 70:1–201, 1965). Here, three infinite families of hemisystems on H(5, q2), q odd, are constructed.
All Norwegian twin pairs born 1967-1974 and still living in Norway in 1992 were invited to a health questionnaire study (Q1). 2,570 pairs (65%) participated. These cohorts and the twin cohorts born 1967-1979 were invited to a new questionnaire study (Q2) in 1998. This time 3,334 pairs (53%) participated. Almost all pairs having participated in the 1998 study were invited to an interview study o...
MOTIVATION Gene class testing (GCT) is a statistical approach to determine whether some functionally predefined classes of genes express differently under two experimental conditions. GCT computes the P-value of each gene class based on the null distribution and the gene classes are ranked for importance in accordance with their P-values. Currently, two null hypotheses have been considered: the...
In this note, we give a precise construction ofone of the families 2-designs arose from studying ŕag-transitive with parameters(v, k, λ) whose replication numbersrare coprime to λ. We show that for given positive integer q=22n+1⩾8, there exists 2-design parameters (q2+ 1, q, q−1) and numberq 2 admitting Suzuki group Sz(q) asits automorphism group. also construct family q(q−1),(q−1)(q2−q−1)) the...
