Stable isotope profiling of burnt wooden safety matches.
Arson is a significant problem around the world, and is a crime which results in a low number of convictions. The scene of an arson can be varied, commercial, residential or national park, and recently cases have been identified which were initiated by a lit match. Matches can be recovered from a scene, usually in a burnt condition. The benefit of analysing unburnt matches has been researched p...
متن کاملDo Weave Matches Imply Canvas Roll Matches?
Computational algorithms for measuring thread counts from scanned x-rays produce warp and weft thread count “maps” across entire paintings. Within the database of over 300 van Gogh paintings, we found a clique of 44 warp-weave-matched paintings. By reconstructing the smallest canvas section that could have produced this match, they must span the entire width of a commercial canvas roll (2+ mete...
متن کاملInterpreting Canvas Weave Matches
Automatic methods of calculating canvas thread counts from x-rays of paintings reveal a systematic pattern for warp and weft thread densities that persists along the respective thread directions. These patterns can be used to find paintings that have matching weave patterns, with warp-thread pattern matches more prevalent than weft-thread matches when trying to associate paintings to the same c...
متن کاملThe Earliest Matches
Cylindrical objects made usually of fired clay but sometimes of stone were found at the Yarmukian Pottery Neolithic sites of Sha'ar HaGolan and Munhata (first half of the 8(th) millennium BP) in the Jordan Valley. Similar objects have been reported from other Near Eastern Pottery Neolithic sites. Most scholars have interpreted them as cultic objects in the shape of phalli, while others have ref...
متن کاملApproximating Matches Made in Heaven
Motivated by applications in online dating and kidney exchange, we study a stochastic matching problem in which we have a random graph G given by a node set V and probabilities p(i, j) on all pairs i, j ∈ V representing the probability that edge (i, j) exists. Additionally, each node has an integer weight t(i) called its patience parameter. Nodes represent agents in a matching market with dicho...
