CASPER‐AI: Machine Learning Applied to Active Collimation in Monolithic Arrays of SDDs

X-Ray Spectrometry, Volume 54, Issue 6, Page 813-818, November/December 2025.
ABSTRACT Monolithic arrays of Silicon Drift Detectors (SDDs) have advanced X‐ray spectroscopy by providing excellent energy resolution and high rates at near ambient temperatures. Despite these benefits, they are affected by charge sharing (CS), where photogenerated charge clouds spread across adjacent channels.

A spark-resistant bulk-micromegas chamber for high-rate applications

, 2010
We report on the design and performance of a spark-resistant bulk-micromegas chamber. The principle of this design lends itself to the construction of large-area muon chambers for the upgrade of the detectors at the Large Hadron Collider at CERN for ...

What Does Iron Mean to an Oligodendrocyte?

Glia, Volume 73, Issue 9, Page 1784-1804, September 2025.
Main Points Iron is essential for oligodendrocyte (OL) biology and myelin production, with deficiencies leading to severe neurological impairments. Understanding iron trafficking in OLs is crucial for developing treatments for dysmyelinating conditions. ABSTRACT Iron is essential for life and plays a key role in multiple fundamental cellular functions.

Wind‐Driven Iron Supply by Ekman Buoyancy Flux Enhances Phytoplankton Bloom in the Antarctic Circumpolar Current

Journal of Geophysical Research: Oceans, Volume 130, Issue 8, August 2025.
Abstract The Southern Ocean today is a globally relevant sink for atmospheric carbon dioxide (CO2 ${\text{CO}}_{2}$), where the biological uptake of carbon through primary productivity is largely controlled by widespread iron (Fe) limitation. We analyze observations from a submesoscale‐resolving cross‐section of the Antarctic Circumpolar Current (ACC ...

Performance of the Charge Injection Capability of Suzaku XIS

, 2007
A charge injection technique is applied to the X-ray CCD camera, XIS (X-ray Imaging Spectrometer) onboard Suzaku. The charge transfer inefficiency (CTI) in each CCD column (vertical transfer channel) is measured by the injection of charge packets into a ...
