The Composition of Comets [PDF]

open access: yesSpace Science Reviews, 2015
This paper is the result of the International Cometary Workshop, held in Toulouse, France in April 2014, where the participants came together to assess our knowledge of comets prior to the ESA Rosetta Mission. In this paper, we look at the composition of the gas and dust from the comae of comets.

Applications and limitations of constrained high-resolution peak fitting on low resolving power mass spectra from the ToF-ACSM [PDF]

open access: yesAtmospheric Measurement Techniques, 2016
The applicability, methods and limitations of constrained peak fitting on mass spectra of low mass resolving power (m∕Δm50 ∼ 500) recorded with a time-of-flight aerosol chemical speciation monitor (ToF-ACSM) are explored. Calibration measurements as well

Cardinal Composition

open access: yesErkenntnis, 2022
AbstractThe thesis of Weak Unrestricted Composition says that every pair of objects has a fusion. This thesis has been argued by Contessa (Analysis 72(3):455–457, 2012) and Smith (Erkenntnis 84(1):41–55, 2019) to be compatible with the world being junky and hence to evade an argument against the necessity of Strong Unrestricted Composition proposed by ...

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.

Emissions of volatile organic compounds from Norway spruce and potential atmospheric impacts

open access: yesFrontiers in Forests and Global Change, 2023
Published biogenic volatile organic compound (BVOC) emission rates of Norway spruces vary a lot. In this study we combined published Norway spruce emission rates measured in boreal forests and added our new, unpublished emission data from Southern (SF ...

Remote sensing measurements during PaCE 2022 campaign [PDF]

open access: yesEarth System Science Data
Continuous ground-based remote sensing measurements were conducted during the Pallas Cloud Experiment (PaCE) 2022 campaign. Remote sensing instruments, including two ceilometers (models CL31 and CL61, Vaisala Oyj), a Doppler cloud radar (model RPG-FMCW ...

Cleaner fuels for ships provide public health benefits with climate tradeoffs

open access: yesNature Communications, 2018
Aerosol pollution from shipping contributes to cooling but also leads to premature mortality and morbidity. Here the authors combine emission inventories, atmospheric models and health risk functions to show how cleaner marine fuels will reduce premature

A composite Higgs with a heavy composite axion [PDF]

open access: yesJournal of High Energy Physics, 2020
Abstract We consider the strong dynamics associated with a composite Higgs model that simultaneously produces dynamical axions and solves the strong CP problem. The strong dynamics arises from a new Sp or SU(4) hypercolor gauge group containing QCD colored hyperfermions that confines at a high scale.

Concentrations and Size Distributions of Particle Lung-deposited Surface Area (LDSA) in an Underground Mine

open access: yesAerosol and Air Quality Research, 2021
Ultrafine particles produced by diesel-powered vehicles in underground mines are largely unaccounted for in mass-based air quality metrics. The Lung Deposited Surface Area concentration (LDSA) is an alternative to describe the harmfulness of particles ...
