Mobile electromagnetic levitator for time‐resolved in situ X‐ray diffraction studies of high‐temperature phase transformations

Journal of Synchrotron Radiation, EarlyView.
A mobile electromagnetic levitator combined with time‐resolved synchrotron X‐ray diffraction enables in situ studies of high‐temperature phase transformations without container‐induced contamination and reveals the first direct observation of metastable phase formation in undercooled Fe–Co alloys.In situ observations of high‐temperature transformations,

Liquid jet capabilities for ultrafast chemistry at the SwissFEL Alvra instrument

Journal of Synchrotron Radiation, EarlyView.
The technical aspects of the Alvra endstation are outlined and its scientific capabilities are demonstrated with commissioning results obtained during the early years of SwissFEL's operation.The Alvra experimental station at the Swiss X‐ray free‐electron laser, SwissFEL, investigates ultrafast dynamics in chemical and biological systems using X‐ray ...

AUGURAL TERRITORIES: On the Prophetic Organizing of the Mid‐range

International Journal of Urban and Regional Research, EarlyView.
Abstract In this article I introduce the concept of augural territories to theorize the urbanism that emerged during pandemic lockdowns. I draw on ethnographic research in Madrid to examine how community‐based responses—including mutual aid networks, food pantries and neighbourhood associations—disrupted the spatial and temporal logics of territorial ...

Rapid hormonal rise in honey bees due to heat‐shock is mitigated by a primer pheromone

Insect Science, EarlyView.
We show that honey bee foragers increased juvenile hormone (JH) titers significantly after heat‐shocked for 1 h at 40 °C, but this increase is dependent on social conditions. Increase of JH titers only happened when bees were isolated (one worker bee per vial) but not in groups.

Ultrasound, PET/CT or temporal artery biopsy for giant cell arteritis? A prospective diagnostic accuracy study (the GAME‐study)

Acta Ophthalmologica, EarlyView.
Abstract Purpose To investigate the diagnostic performance of ultrasound, 2‐deoxy‐2‐[18F]fluoro‐D‐glucose positron emission tomography/computed tomography (2‐[18F]FDG PET/CT) and temporal artery biopsy (TAB) in giant cell arteritis (GCA). Methods This was a prospective single‐centre diagnostic accuracy study (ClinicalTrials.gov NCT05248906).

A Multi‐Analytical Approach for the Compositional Characterization and Chronological Discrimination of Benin (Nigeria) Metal Sculptures

Archaeometry, EarlyView.
ABSTRACT This study presents a multi‐analytical archaeometric approach for the compositional characterization and chronological discrimination of Benin metal sculptures in relation to the 1897 Punitive Expedition. The methodology integrates elemental composition (XRF and ICP), stable lead isotope ratios (MC‐ICP‐MS) for alloy system characterization ...
