Pollen analysis of sediment core from Yukashigata Lagoon, western Japan: revealing human induced paleovegetation changes during the past 1500 years

open access: yesTerrestrial, Atmospheric and Oceanic Sciences
A 292 cm-long sediment core was collected from the center of Yukashigata Lagoon using a Mackereth air-pressure piston corer. Pollen analysis with radiocarbon dating of this sediment core was conducted to reconstruct the surrounding paleoenvironment.

Dynamic sampling for SAXSTT: towards real‐time measurement adaptation

open access: yesJournal of Synchrotron Radiation, EarlyView.
A dynamic sampling strategy is presented to reduce the measurement time required for SAXS tensor tomography while maintaining reconstruction quality.Small‐angle X‐ray scattering tensor tomography (SAXSTT) is a powerful technique for non‐destructive 3D characterization of nanoscale structures by reconstructing q‐resolved reciprocal space maps.
