Immediate and long‐term impact of the COVID‐19 pandemic on delivery of surgical services
BJS (British Journal of Surgery), Volume 107, Issue 10, Page 1250-1261, September 2020., 2020 Surgical services are adapting to mitigate the surge in patients with COVID‐19 in need of critical care support. All non‐essential elective surgery has been cancelled, or is pending cancellation, in healthcare systems around the globe, impacting millions of patients.

Post-Hopf algebras, relative Rota–Baxter operators and solutions to the Yang–Baxter equation
Journal of Noncommutative Geometry, 2023 In this paper, first, we introduce the notion of post-Hopf algebra, which gives rise to a post-Lie algebra on the space of primitive elements and the fact that there is naturally a post-Hopf algebra structure on the universal enveloping algebra of a post-Lie algebra. A novel property is that a cocommutative post-Hopf algebra gives rise to a generalized

Linking behavioral thermoregulation, boldness, and individual state in male Carpetan rock lizards
Ecology and Evolution, Volume 10, Issue 18, Page 10230-10241, September 2020., 2020 Body temperature is a major ecophysiological variable in poikilotherms with a direct link to a variety of fitness‐related traits. As most poikilotherms are capable of maintaining relatively high and constant body temperatures by behavioural adjustments, we tested whether behavioural thermoregulatory strategy are linked to boldness and individual state ...

Free integro-differential algebras and Groebner-Shirshov bases [PDF]
, 2014 The notion of commutative integro-differential algebra was introduced for the algebraic study of boundary problems for linear ordinary differential equations. Its noncommutative analog achieves a similar purpose for linear systems of such equations.

Relative Rota-Baxter operators and symplectic structures on Lie-Yamaguti algebras
Communications in Algebra, 2022 In this paper, first we introduce the notion of a quadratic Lie-Yamaguti algebra and show that the invariant bilinear form in a quadratic Lie-Yamaguti algebra induces an isomorphism between the adjoint representation and the coadjoint representation. Then we introduce the notions of relative Rota-Baxter operators on Lie-Yamaguti algebras and pre-Lie ...

Lie theory and cohomology of relative Rota-Baxter operators [PDF]
, 2022 In this paper, we establish a local Lie theory for relative Rota-Baxter operators of weight $1$. First we recall the category of relative Rota-Baxter operators of weight $1$ on Lie algebras and construct a cohomology theory for them.

Rota-Baxter operators and Bernoulli polynomials [PDF]
, 2021 summary:We develop the connection between Rota-Baxter operators arisen from algebra and mathematical physics and Bernoulli polynomials. We state that a trivial property of Rota-Baxter operators implies the symmetry of the power sum polynomials and ...

Bimodules over relative Rota-Baxter algebras and cohomologies [PDF]
, 2022 A relative Rota-Baxter algebra is a generalization of a Rota-Baxter algebra. Relative Rota-Baxter algebras are closely related to dendriform algebras.
