210Pb-based dating of recent sediments with the χ-mapping version of the Constant Sediment Accumulation Rate (CSAR) model

, 2023
The 210Pb-based method aims at determining the absolute age of recent sediments on the centennial scale. A family of models assumes that at the sediment-water interface the flux of unsupported 210Pb ( 210Pbexc), F, relates to its initial activity ...

Deterministic Integration of Quantum Emitters and Optical Cavities in a Van Der Waals Crystal

Advanced Optical Materials, Volume 14, Issue 31, August 21, 2026.
The work demonstrates fabrication of Circular Bragg Grating (CBG) cavities with embedded emitters in hBN. The cavities are fabricated around a pre‐characterised quantum emitter. The integrated platform enables light matter interaction and access to brighter emitters and spins in hBN.

CSAR 2014: A Benchmark Exercise Using Unpublished Data from Pharma [PDF]

Journal of Chemical Information and Modeling, 2016
The 2014 CSAR Benchmark Exercise was the last community-wide exercise that was conducted by the group at the University of Michigan, Ann Arbor. For this event, GlaxoSmithKline (GSK) donated unpublished crystal structures and affinity data from in-house projects. Three targets were used: tRNA (m1G37) methyltransferase (TrmD), Spleen Tyrosine Kinase (SYK)

Interlayer‐Catalyst Method for Metal‐Assisted Chemical Etching of Ultra‐High Aspect Ratio Silicon Nanostructures

Small Methods, Volume 10, Issue 16, 25 August 2026.
An advanced patterning method is presented for metal‐assisted chemical etching. The interlayer replaces the resist and enables catalyst deposition on a clean interface. The prepared samples show improved performance with a more reproducible etching profile, higher aspect ratio, and increased consistency over a larger area.

Modelling the Four‐Dimensional Power Line Sag Dynamics by Point Signature in Time‐Series Synthetic‐Aperture Radar Images

High Voltage, Volume 11, Issue 4, Page 1090-1101, August 2026.
ABSTRACT Power lines in synthetic‐aperture radar (SAR) images are reflected as point signatures, which fluctuate annually in both the azimuth and range directions. A novel framework is proposed in this paper to evaluate the four‐dimensional dynamic status of power line sag using those point signatures in time‐series SAR images.
