A beam‐direction cross‐vessel metrology method and error analysis for the ptychography setup at HEPS ID09

Journal of Synchrotron Radiation, EarlyView.
A beamline‐direction cross‐vessel metrology method and error analysis for ptychography setup at HEPS ID09 is proposed and implemented. A 12.3 nm reconstruction resolution of ptychography demonstrates the validity of metrology.A metrology method dedicated to position monitoring and correction for the ptychography setup at the High Energy Photon Source ...

One million scans later: the evolution of the I16 material and magnetism beamline at Diamond Light Source

Journal of Synchrotron Radiation, EarlyView.
Beamline I16 at Diamond Light Source is a versatile X‐ray scattering instrument that combines tunable X‐ray energy and polarization, flexible diffraction geometries, and advanced sample environments for studies of electronic, magnetic, and structural phenomena.Here, we review the capabilities of beamline I16 at Diamond Light Source after nearly 20 ...

Structure design and implementation of a water cooling sub‐20 nm multilayer Kirkpatrick–Baez mirror system in the Structural Dynamics beamline ID23 at HEPS

Journal of Synchrotron Radiation, EarlyView.
A water‐cooling nano multilayer Kirkpatrick–Baez mirrors system has been implemented at ID23 HEPS. The focal spot size of 13.39 nm × 15.15 nm (H × V) at a photon energy of 21.8 keV demonstrates the system's performance.The first water‐cooling nano multilayer Kirkpatrick–Baez mirror system in the Structural Dynamics beamline (ID23) at High Energy Photon

Biological invasions disrupt the relationship between size spectrum and trophic interactions in freshwater fish communities

Journal of Animal Ecology, EarlyView.
Our study shows that non‐native species alter the relationship between the size‐spectrum slope and the predator–prey mass ratio (PPMR) in freshwater fish communities by occupying distinct trophic niches. Abstract The size spectrum, which describes the relationship between abundance (or biomass) and body size, is an ataxic approach that can provide ...

Boredom, despondency, and the scourge that lays waste at noon: an anthropology of acedia Ennui, abattement et le fléau qui frappe à midi : une anthropologie de l'acédie

Journal of the Royal Anthropological Institute, EarlyView.
Attentive to the ways that inertia can take hold of life, Catholic monks recognize despondency as a potential not only within the monastery, but in contemporary society more widely. Such experiences are regularly mapped onto an understanding of what early Christian monks termed ‘acedia’ (a Greek term that can be translated as ‘lack of care’). Taking as
