Undetected biogenic volatile organic compounds from Norway spruce drive total ozone reactivity measurements [PDF]

open access: yesAtmospheric Chemistry and Physics, 2023
Biogenic volatile organic compounds (BVOCs) are continuously emitted from terrestrial vegetation into the atmosphere and react with various atmospheric oxidants, with ozone being an important one.

On Composition of Torsors

open access: yesInternational Mathematics Research Notices, 2023
AbstractLet $K$ be a field, let $X$ be a connected smooth $K$-scheme, and let $G,H$ be two smooth connected $K$-group schemes. Given $Y \to X$ a $G$-torsor and $Z \to Y$ an $H$-torsor, we study whether one can find an extension $E$ of $G$ by $H$ so that the composite $Z \to X$ is an $E$-torsor.

Evaluation of novel beverage formulations for hydration enhancement in humans

open access: yesJournal of Electrical Bioimpedance, 2023
This study evaluated the influence of novel beverage formulations on bioimpedance- and urine-based hydration markers. Thirty young healthy adults (n=16 females, n=14 males; age: 23.2±3.7 years; BMI: 24.3±3.3 kg/m2) participated in a randomized, double ...

Complexity of downy birch emissions revealed by Vocus proton transfer reaction time-of-flight mass spectrometer

open access: yesFrontiers in Forests and Global Change, 2022
Biogenic volatile organic compounds (BVOCs) are known to strongly influence the global climate by affecting various atmospheric constituents such as oxidants and aerosols. Among the several BVOCs that are emitted continuously into the atmosphere, studies

Laboratory evaluation of particle-size selectivity of optical low-cost particulate matter sensors [PDF]

open access: yesAtmospheric Measurement Techniques, 2020
Low-cost particulate matter (PM) sensors have been under investigation as it has been hypothesized that the use of low-cost and easy-to-use sensors could allow cost-efficient extension of the currently sparse measurement coverage.

Influence of acute water ingestion and prolonged standing on raw bioimpedance and subsequent body fluid and composition estimates

open access: yesJournal of Electrical Bioimpedance, 2022
This study evaluated the influence of acute water ingestion and maintaining an upright posture on raw bioimpedance and subsequent estimates of body fluids and composition. Twenty healthy adults participated in a randomized crossover study.

Rydberg Composites [PDF]

open access: yesPhysical Review X, 2020
We introduce the Rydberg Composite, a new class of Rydberg matter where a single Rydberg atom is interfaced with a dense environment of neutral ground state atoms. The properties of the Composite depend on both the Rydberg excitation, which provides the gross energetic and spatial scales, and on the distribution of ground state atoms within the volume ...
