Connection matrices for graph parameters with values in a field have been introduced by M. Freedman, L. Lovász and A. Schrijver (2007). Graph parameters with connection matrices of finite rank can be computed in polynomial time on graph classes of bounded tree-width. We introduce join matrices, a generalization of connection matrices, and allow graph parameters to take values in the tropical ri...

An approximately analysis study of the collinear approach for $t\overline{t}$ production at Future Circular Collider hadron-electron (FCC-he) and Large Hadron electron (LHeC) is performed. To heavy quark processes, generalized double asymptotic scaling (DAS) in a wide rang $Q^{2}$ used. The reduced cross sections top pair FCC-he (for $Q^{2}{\geq}m^{2}_{t}$) LHeC $Q^{2}{\leq}m^{2}_{t}$) center-o...

This paper proposes the first model-based clustering algorithm dedicated to multivariate partial ranking data. This is an extension of the Insertion Sorting Rank (isr) model for ranking data, which is a meaningful and effective model obtained by modelling the ranking generating process assumed to be a sorting algorithm. The heterogeneity of the rank population is modelled by a mixture of isr, w...

BACKGROUND Nowadays, medicinal plants are used as a popular alternative to synthetic drugs. Many medicinal plant products have now been commercialized throughout various markets. These products are commonly sold in processed or modified forms such as powders, dried material and capsules, making it almost impossible to accurately identify the constituent species. The herbal plant known as 'Rang ...

— Let R be a 2-dimensional normal excellent henselian local domain in which 2 is invertible and let L and k be its fraction field and residue field respectively. Let ΩR be the set of rank 1 discrete valuations of L corresponding to codimension 1 points of regular proper models of Spec R. We prove that a quadratic form q over L satisfies the local-global principle with respect to ΩR in the follo...

This paper combines ISSP survey data and experimental evidence from a giftexchange game to determine the effect of status or relative income on work effort. We find a strong effect of others’ incomes on individual effort decisions in both datasets. The individual’s rank in the income distribution has a more powerful effect on effort than does others’ average income, suggesting that comparisons ...
