How many shots are enough? Optimizing precision measurements when testing lead‐free ammunition
Wildlife Biology, EarlyView.Growing concern about lead exposure in scavenging wildlife and the consumers of game meat has increased interest in evaluating the performance of lead‐free rifle ammunition. Testing both accuracy and precision helps ensure reliable shot placement while reducing the risk of non‐fatal woundings.

Journal of the Royal Anthropological Institute, EarlyView.Recent years have seen landmark progress in our understanding of early Homo sapiens occupation of Europe, owing to new excavations and the application of new analytical methods. Research on British sites, however, continues to lag. This is because of limitations inherent in existing cave collections, and limited options for new fieldwork at known sites.

Ramsey Numbers and Two-colorings ofComplete Graphs
, 2015 Ramsey theory has to do with order within disorder. This thesis studies two Ramsey numbers, R(3; 3) and R(3; 4), to see if they can provide insight into finding larger Ramsey numbers. The numbers are studied with the help of computer programs.

Canonical Ramsey numbers and properly colored cycles
, 2009 We improve the previous bounds on the so-called unordered Canonical Ramsey numbers, introduced by Richer [D. Richer, Unordered canonical Ramsey numbers, Journal of Combinatorial Theory Series B 80 (2000) 172–177] as a variant of the canonical Ramsey ...

Insights from the Presidential Addresses to the Agricultural Economics Society
Journal of Agricultural Economics, EarlyView.ABSTRACT The Society's published presidential addresses have embraced a wide range of subject matter, reflecting a ‘road well travelled’ in agricultural economics. The areas covered include the development and use of data and statistics, lessons from history, sectoral analysis, land economics, international trade and international development.

, 2011 The graph Ramsey number R(G,H) is the smallest integer r such that every 2-coloring of the edges of Kr contains either a red copy of G or a blue copy of H.

Ramsey numbers of books and quasirandomness [PDF]
, 2020 The book graph B^((k))_n consists of n copies of K_(k+1) joined along a common K_k. The Ramsey numbers of B^((k))_n are known to have strong connections to the classical Ramsey numbers of cliques.

Market Integration and Nonlinear Price Transmission in 19th‐Century British Wheat Markets
Journal of Agricultural Economics, EarlyView.ABSTRACT Important developments in infrastructure and institutions characterized 19th‐Century wheat markets in Great Britain. Among these developments was the construction of the national rail system which enabled cheaper and more efficient transport of grain and other bulky cargoes between inland towns and ports.

RAMSEY NUMBERS FOR PARTIALLY-ORDERED SETS
, 2015 We present a refinement of Ramsey numbers by considering graphs with a partial ordering on their vertices. This is a natural extension of the ordered Ramsey numbers. We formalize situations in which we can use arbitrary families of partially-ordered sets

Ramsey numbers and graph parameters [PDF]
According to Ramsey’s Theorem, for any natural p and q there is a minimum number R(p, q) such that every graph with at least R(p, q) vertices has either a clique of size p or an independent set of size q. In the present paper, we study Ramsey numbers R(p,
