Notes on Whitehead space of an algebra

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2002
Let R be a ring, and denote by [R,R] the group generated additively by the additive commutators of R. When Rn=Mn(R) (the ring of n×n matrices over R), it is shown that [Rn,Rn] is the kernel of the regular trace function modulo [R,R].

Analytic Detection in Homotopy Groups of Smooth Manifolds

open access: yesСовременная математика: Фундаментальные направления, 2020
In this paper, for the mapping of a sphere into a compact orientable manifoldSn→M,n⩾1, we solve the problem of determining whether it represents a nontrivial element in the homotopy group of the manifoldπn(M) πn(M ). For this purpose, we consistently use

Pollination by long‐proboscid horseflies and its implications for reproductive isolation among coflowering Satyrium orchids in South Africa

open access: yesAmerican Journal of Botany, EarlyView.
Abstract Premise Floral adaptations to pollinators can drive lineage diversification and promote coexistence of species. We investigated the reproductive biology of Satyrium longicolle, a South African orchid that we hypothesized to belong to a long‐proboscid horsefly pollination guild and examined overlap of pollinators and floral traits among ...

Tobramycin pharmacokinetic and pharmacodynamic targets in people with cystic fibrosis

open access: yesBritish Journal of Clinical Pharmacology, EarlyView.
Intravenous tobramycin is a first‐line treatment for Pseudomonas aeruginosa infection in people with cystic fibrosis (CF). Tobramycin exhibits concentration‐dependent activity; however, excess drug exposure can lead to nephrotoxicity and ototoxicity. While dosing typically targets serum peak (Cmax) and trough (Cmin) concentrations, the area under the ...
