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

open access: yesJournal 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,

Distributed computing for the reconstruction of multi‐terabyte tomographic X‐ray imaging datasets

open access: yesJournal of Synchrotron Radiation, EarlyView.
As tomographic datasets from synchrotrons continue to increase in volume, so rises the challenge of reconstructing said data. Here we present a solution utilizing high‐performance computing capabilities to split the process into multiple smaller tasks, which can be solved without overwhelming a single compute node.

High‐flux, moderate‐bandwidth, high‐energy X‐rays from lapped Si(111) crystals in a double‐crystal monochromator

open access: yesJournal of Synchrotron Radiation, EarlyView.
Lapped Si(111) crystals in a double‐crystal monochromator provide high‐flux, spectrally pure, and moderate‐bandwidth X‐ray beams at 100 keV, offering a robust and cost‐effective alternative to perfect‐crystal and multilayer optics.Lapping the surfaces of Si(111) crystals in a double‐crystal monochromator significantly increases the intensity of high ...

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

open access: yesInternational 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

open access: yesInsect 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.

Stable flies preferentially oviposit on sites offering conspecific eggs with egg‐derived bacterial semiochemicals

open access: yesInsect Science, EarlyView.
Stable flies preferentially oviposit on sites offering conspecific eggs with egg‐derived airborne semiochemicals. Egg‐borne bacterial symbionts, and Serratia marcescens in particular, produce odorants which attract gravid female flies and elicit oviposition.

Becoming monstrous: Beauty norms, body image, and discursive limits on compassion in The Substance

open access: yesNutrition &Dietetics, EarlyView.
Abstract Aim This study analyses the Hollywood body horror film The Substance to explore how Western beauty culture regulates emotions and bodies. It aims to explore compassion within dominant body image discourses and considers how this impacts dietetic care. Methods Using Foucauldian discourse analysis informed by affect theory, the film was analysed

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

open access: yesActa 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).
