Dating the Middle Palaeolithic of Fumane Cave by the combined ESR/U‐series method

open access: yesJournal of Quaternary Science, EarlyView.
ABSTRACT Fumane Cave, located in Northern Italy, is a major prehistoric site for understanding late Neandertal and early modern human behaviours. The cave contains a 12‐m‐thick stratigraphic sequence of Middle and Upper Palaeolithic layers, which have yielded a number of flint artefacts and faunal remains.

Diagrammatic Schemes for Nonlinear Optical Interactions

open access: yesJournal of Raman Spectroscopy, EarlyView.
Conventional diagrammatic approaches (blue frames in the figure) to semi‐classical nonlinear optical interactions emphasize either the bra and ket matter states (double‐sided Feynman diagrams and Liouville pathways) or the frequencies of the bra and ket radiative processes between energy levels (Albrecht notation). We propose a field‐type modification (

Forecasting climate and human alterations to coastal and estuarine dissolved organic matter

open access: yesLimnology and Oceanography Letters, EarlyView.
Abstract River networks serve as conduits for dissolved organic matter (DOM) and carbon (DOC) from inland to coastal waters. Human activities and climate change are altering DOM sources, causing hydrological and biogeochemical shifts that impact DOC concentrations and changing the transport and transformation of DOM and DOC. Here, we synthesize current

‘Don’t think that we die from AIDS’: Invisibilised uncertainty and global transgender health

open access: yesSociology of Health &Illness, Volume 45, Issue 1, Page 196-212, January 2023., 2023
Abstract The invisibilisation of social groups in health research and survey data is a source of medical uncertainty, long seen as a hallmark of the medical field. However, scholarship has not thoroughly assessed how medical uncertainty is structured by state‐level processes and global health agendas, especially for people beyond the Global North. This

Ion Chemistry in Dielectric Barrier Discharge Ionization: Recent Advances in Direct Gas Phase Analyses

open access: yesMass Spectrometry Reviews, EarlyView.
ABSTRACT Dielectric barrier discharge ionization (DBDI) sources, employing low‐temperature plasma, have emerged as sensitive and efficient ionization tools with various atmospheric pressure ionization processes. In this review, we summarize a historical overview of the development of DBDI, highlighting key principles of gas‐phase ion chemistry and the ...
