Hamilton cycles and algorithms
, 2022 We present three results in graph theory, united by the themes of Hamilton cycles and algorithms. A Hamilton cycle in a graph is a cycle that contains every vertex of the graph. The first result concerns path decompositions of digraphs, specifically an extension of a conjecture due to Alspach, Mason, and Pullman.

Have Business Cycles Become More Synchronous After NAFTA?
American Business Review, 2021 Trade agreements do not necessitate business cycle comovement. Focusing on NAFTA, we investigate whether business cycles in Canada, Mexico, and the US have become more synchronous after the landmark trade agreement came into effect in 1994.

Decomposition into Cycles I: Hamilton Decompositions [PDF]
, 1990 In this part we survey the results concerning the partitions of the edge-set of a graph into Hamilton cycles or into Hamilton cycles and a single perfect matching.

Advanced Functional Materials, EarlyView.This study develops a novel atomic engineering strategy to fine‐tune the spin state of α‐Fe2O3 catalysts toward a medium‐spin state, thereby modulating peroxymonosulfate activation and selectively yielding surface‐bound radicals. Compared with free radicals, surface‐bound radicals exhibit moderated oxidation potential, extended lifespan, surface ...

Advanced Healthcare Materials, EarlyView.The pyrogallol‐conjugated carboxymethylcellulose (CMC‐PG) hydrogel is applicated as a filler for the treatment of presbylaryngis, a vocal fold atrophy. CMC‐PG provides a bulking effect to the vocal folds. CMC‐PG is readily injectable and tissue adhesive, enabling sustained release of growth factor over long period.

Hamilton cycles in quasirandom hypergraphs [PDF]
Random Structures & Algorithms, 2016 We show that, for a natural notion of quasirandomness in $k$-uniform hypergraphs, any quasirandom $k$-uniform hypergraph on $n$ vertices with constant edge density and minimum vertex degree $ (n^{k-1})$ contains a loose Hamilton cycle. We also give a construction to show that a $k$-uniform hypergraph satisfying these conditions need not contain a ...

Advanced Healthcare Materials, EarlyView.Injectable POEGMA‐DA hydrogels, dual‐crosslinked via dopamine self‐polymerization and dynamic hydrazone bonds, provide a safer alternative to invasive wound closure methods and toxic bioadhesives. Mimicking skin‐like mechanics, they achieve effective tissue adhesion for acute dermal wounds, supporting improved healing outcomes, including reducing ...
