Brunet, Johanne (Ed.)Abstract Honey bees (Apis mellifera L. Hymeoptera: Apidae) use hydrogen peroxide (synthesized by excreted glucose oxidase) as an important component of social immunity. However, both tolerance of hydrogen peroxide and the production of glucose oxidase in honey is costly. Hydrogen peroxide may also be encountered by honey bees at high concentrations in nectar while foraging, however despite its presence both in their foraged and stored foods, it is unclear if and how bees monitor concentrations of, and their behavioral responses to, hydrogen peroxide. The costs of glucose oxidase production and the presence of hydrogen peroxide in both nectar and honeymore »Free, publicly-accessible full text available January 1, 2023

We enumerate factorizations of a Coxeter element into arbitrary factors in the complex reflection groups G(d, 1, n) (the wreath product of the symmetric group with a cyclic group) and its subgroup G(d, d, n), applying combinatorial and algebraic methods, respectively. After a change of basis, the coefficients that appear are the same as those that appear in the corresponding enumeration in the symmetric group.

In this paper we describe a virtual reality training simulation designed to help police officers learn use of force policies. Our goal is to test a training simulation prototype by measuring improvements to presence and performance. If successful, this can lead to creating a full-scale virtual reality narrative training simulation. The simulation uses a planner-based experience manager to determine the actions of agents other than the participant. Participants’ actions were logged, physiological data was recorded, and the participants filled out questionnaires. Player knowledge attributes were authored to measure participants’ understanding of teaching materials. We demonstrate that when participants interact withmore »

Diégues, M. ; Bäckvall, J.-E. ; Pàmies, O. (Ed.)Transition metal catalysts and enzymes are ubiquitous tools for chemical synthesis. Potential benefits of combining complementary properties of these catalysts have driven efforts to create artificial metalloenzymes (ArMs), hybrid constructs comprised of synthetic metal centers embedded within protein scaffolds. This unique composition necessitates the use of synthetic chemistry, bioconjugation methodology, and protein engineering for ArM formation. Despite this challenge, a range of approaches for ArM formation have been developed. This review provides an overview these different approaches and discussion of potential advantages and disadvantages of each.
