Research progress on correlations between trace element levels and epilepsy

Frontiers in Cell and Developmental Biology, 2023
Research investigating the correlation between human trace element levels and disease alterations is growing. Epilepsy, a common nervous system disease, has also been found to be closely related to abnormal levels of trace elements.

Partial Traces on Additive Categories

Electronic Notes in Theoretical Computer Science, 2018
Abstract In this paper, we study partial traces on additive categories. Haghverdi and Scott introduced partially traced symmetric monoidal categories generalizing traced symmetric monoidal categories given by Joyal, Street and Verity. The original example of a partial trace is given in terms of the execution formula on the category of vector spaces ...

The Additivity of Traces in Triangulated Categories

Advances in Mathematics, 2001
The author states a theorem on the additivity of the Euler characteristic -- or more generally, a suitably defined trace -- when applied to distinguished triangles of suitably dualizable objects in a refined notion of triangulated category. The main point of the paper is to write down the axioms needed to make such a theorem true, and to provide ...
