Genetic-epidemiological studies on monozygotic (MZ) twins have been used for decades to tease out the relative contributions of genes and the environment to a trait. Phenotypic discordance in MZ twins has traditionally been ascribed to non-shared environmental factors acting after birth, however recent data indicate that this explanation is far too simple.(More)
Studies were performed in the years 1986-1990 and dealing with 405 clinical materials originating from infections within the abdominal cavity, maxilla, reproductive organ, post-operative wounds as well as dressings, extremities, blood, bile and other types of material and usefulness of analysis by gas chromatography of presence of lower fatty acids in(More)
In the framework of the dipole picture of the BFKL pomeron we discuss a few possibilities of calculating the total γγ cross section of the virtual photons. We argue that the existing successful fits of the dipole picture formulae to the measured structure functions F2(Q , x) favor one of the possible extensions of the dipole picture of the BFKL pomeron(More)
It is pointed out that the average semi-inclusive particle phasespace density at freeze-out can be determined from the coincidence probability of the events observed in multiparticle production. The method of measurement is described and its accuracy examined. 1. Recently, several methods were proposed which allow to estimate the average of the(More)

We present the first measurement of pseudorapidity densities of primary charged particles near midrapidity in Au+Au collisions at sqrt[s(NN)] = 56 and 130 GeV. For the most central collisions, we find the charged-particle pseudorapidity density to be dN/deta|(|eta|<1) = 408+/-12(stat)+/-30(syst) at 56 GeV and 555+/-12(stat)+/-35(syst) at 130 GeV, values(More)
It is pointed out that the moments of phase-space particle density at freeze-out can be determined from the coincidence probabilities of the events observed in multiparticle production. A method to measure the coincidence probabilities is described and its validity examined. PACS numbers 25.75.Gz, 13.65.+i Bose-Einstein correlations, interaction region(More)
Relation between Renyi entropies and moments of the Wigner function, representing the quantum mechanical description of the Mparticle semi-inclusive distribution at freeze-out, is investigated. It is shown that in the limit of infinite volume of the system, the classical and quantum descriptions are equivalent. Finite volume corrections are derived and(More)
