SUPECA kinetics for scaling redox reactions in networks of mixed substrates and consumers and an example application to aerobic soil respiration [PDF]

open access: yesGeoscientific Model Development, 2017
Several land biogeochemical models used for studying carbon–climate feedbacks have begun explicitly representing microbial dynamics. However, to our knowledge, there has been no theoretical work on how to achieve a consistent scaling of the complex ...

Open Prebiotic Environments Drive Emergent Phenomena and Complex Behavior

open access: yesLife, 2019
We have been studying simple prebiotic catalytic replicating networks as prototypes for modeling replication, complexification and Systems Chemistry. While living systems are always open and function far from equilibrium, these prebiotic networks may be ...

A chemical probe technique for the determination of reactive halogen species in aqueous solution: Part 1 – bromide solutions [PDF]

open access: yesAtmospheric Chemistry and Physics, 2006
Reactive halogen species (X*=X•, •X2-, X2 and HOX, where X=Br, Cl, or I) in seawater, sea-salt particles, and snowpacks play important roles in the chemistry of the marine boundary layer.

Clinical and laboratory characteristics of children with sickle cell disease on hydroxyurea treated with artemether-lumefantrine for acute uncomplicated malaria

open access: yesFrontiers in Medicine, 2023
IntroductionLimited information exists on any interactions between hydroxyurea (HU) and antimalarials in sickle cell disease (SCD). We evaluated changes in clinical and laboratory parameters among children with SCD on HU therapy treated with artemether ...

Disentangling the chemistry and transport impacts of the quasi-biennial oscillation on stratospheric ozone [PDF]

open access: yesAtmospheric Chemistry and Physics
The quasi-biennial oscillation (QBO) in tropical winds perturbs stratospheric ozone throughout much of the atmosphere via changes in transport of ozone and other trace gases, as well as via temperature changes, both of which alter ozone chemistry ...
