Cost Pass‐Through in Crisis: Evidence From the German Malt‐Beer Supply Chain
Agribusiness, EarlyView.Abstract Global agri‐food supply chains are increasingly exposed to geopolitical shocks, climate volatility, and market consolidation, factors that disrupt traditional price relationships and reshape market power dynamics. Nowhere is this more visible than in the brewing sector, where agricultural raw materials meet complex industrial processing and ...

Almost-Rainbow Edge-Colorings of Some Small Subgraphs
Discussiones Mathematicae Graph Theory, 2013 Let f(n, p, q) be the minimum number of colors necessary to color the edges of Kn so that every Kp is at least q-colored. We improve current bounds on these nearly “anti-Ramsey” numbers, first studied by Erdös and Gyárfás.

Combinatorial properties of the enhanced principal rank characteristic sequence over finite fields
Special Matrices, 2021 The enhanced principal rank characteristic sequence (epr-sequence) of a symmetric matrix B ∈ 𝔽n×n is defined as ℓ1ℓ2· · · ℓn, where ℓj ∈ {A, S, N} according to whether all, some but not all, or none of the principal minors of order j of B are nonzero ...

Agribusiness, EarlyView.ABSTRACT Brazil and the United States account for more than 40% of global poultry exports, with China and South Korea among their major destination markets. This study examines price transmission and market linkages between Brazil and the United States using monthly poultry export price data from January 1990 to December 2024. It also assesses which of

Weakened Gallai-Ramsey numbers [PDF]
Surveys in Mathematics and its Applications, 2018 In the Ramsey theory of graphs, one seeks to determine the value of the Ramsey number rt(n), defined to be the least natural number p such that every coloring of the edges of Kp using t colors results in a monochromatic copy of Kn in some color.

Ramsey numbers of partial order graphs (comparability graphs) and implications in ring theory
Open Mathematics, 2020 For a partially ordered set (A,≤)(A,\le ), let GA{G}_{A} be the simple, undirected graph with vertex set A such that two vertices a≠b∈Aa\ne b\in A are adjacent if either a≤ba\le b or b≤ab\le a.

Animal Research and One Health, EarlyView.Woody breast compromises meat quality leading to reduced consumer appeal. Although its causes are unclear, improvements observed with certain dietary supplements suggest that gut health may influence woody breast development. Ribonucleotide reductase subunit RRM2 is vital for mitochondrial function and gastrointestinal integrity, and alteration in its ...

, 2023 U ovom diplomskom radu razmotrili smo osnovne teoreme Ramseyjeve teorije te se također usredotočili na ranu fazu njezina razvoja. Pokazali smo kako je računanje Ramseyjevih brojeva vrlo zahtjevan proces, pri čemu je do danas poznato samo 9 netrivijalnih ...

The Electronic Journal of Combinatorics, 2004 There are many interesting applications of Ramsey theory, these include results in number theory, algebra, geometry, topology, set theory, logic, ergodic theory, information theory and theoretical computer science. Relations of Ramsey-type theorems to various fields in mathematics are well documented in published books and monographs.

Arthritis &Rheumatology, EarlyView.Objective Methotrexate (MTX) is the first‐line therapy for juvenile idiopathic arthritis (JIA), but up to 40% of patients do not respond to it. Low inosine triphosphate pyrophosphatase (ITPA) activity has been associated with reduced clinical remission. We investigated the role and underlying mechanisms of ITPA in vitro. Methods ITPA enzymatic activity
