We discuss the Skyrmemodel for strong interactions and the concept of a Skyrmion fluid. The corresponding compact objects, namely Skyrmion stars, constructed from the equation of state describing such a fluid are presented and compared to models of neutron stars based on modern equation of states. We suggest plausible Skyrmion star candidates in the 4U 1636−53 and 4U 1820−30 low mass X-ray bina...

This paper provides systematic presentation of the issues related to methodology, and offers some possible solutions for analysis of different aspects of child development, especially preschool age. These issues are related to the definition, acceptance and preparation of the existing theories on development, which include analysis of the whole child's self his/her surroundings, and his/her act...

Usually, in monitoring a proportion p < /em>, the binary observations are considered independent; however, in many real cases, there is a continuous stream of autocorrelated binary observations in which a two-state Markov chain model is applied with first-order dependence. On the other hand, the Bernoulli CUSUM control chart which is not robust to autocorrelation can be applied two-sided co...

A finite probability mixture model is combined with a contingent valuation model to analyze the existence of differential market segments in a hypothetical market. The approach has at least two principle benefits. First, the model is capable of identifying market segments within the hypothetical market. Second, the model can be used to estimate WTP/WTA within each segment. The model is illustra...

In this article the behavior of tetrahydrofuran (THF) + 2-alkanol namely 2-propanol, 2-butanol, 2-pentanol, 2-hexanol and 2-heptanol binary mixtures through the density and viscosity measurements have been studied as a function of composition and within the temperature range of 293.15–313.15 K. The excess molar volume, isobaric thermal expansivity, partial molar volumes, and viscosity deviation...

We introduce a tractable multi-issue model of electoral competition in which candidates are exogenously committed to particular positions on a subset of issues, while they can choose a sequence of binary positions for the remaining issues to maximize their winning probability. A majorityefficient position is defined as one where a candidate cannot make a majority of the electorate better off, t...

Abstract We draw a multimessenger picture of J1048+7143, flat-spectrum radio quasar known to show quasiperiodic oscillations in the ? -ray regime. generate adaptively binned Fermi Large Area Telescope light curve this source above 168 MeV find three major flares source, such that each consists two sharp subflares. Based on interferometric imaging data taken with Very Array, we kiloparsec-scale ...

A review is given of the status of hypotheses about various undiscovered particles. Magnetic monopoles, intermediate bosons, heavy leptons, scalar particles, quarks, tachyons and gravitons are discussed, along with speculations about the newly discovered neutral mesons. This review was completed in December 1974. Rep. Prog. Phys. 1975 38 731-770
