AB Dor: Coronal Imaging and Activity Cycles

The Astrophysical Journal
Using long-term X-ray observations, we present short-term and long-term X-ray variability analysis of the ultrafast rotating active star AB Dor. Flaring events are common in X-ray observations of AB Dor and occupy a substantial portion of the total ...

From Flybys to Sample Return: A Review of Space Probes and Robotic Sampling Technologies for Small Bodies

Journal of Field Robotics, EarlyView.
ABSTRACT As a crucial puzzle piece of deep space exploration, exploring small bodies can provide significant scientific insights and valuable mineral resources. Unlike missions to the Moon and Mars, small‐body missions pose distinct technical challenges, including communication delays, weak gravity, and uncertain environments. This paper reviews a full

Individualization and Purification of Carbon Nanothreads

Small, EarlyView.
Reductive dissolution enables the solution processing of carbon nitride nanothreads into individualized nanothreads that can be assembled into ultrathin films. The resulting interconnected networks exhibit weakly semiconducting behavior, with the conductivity decreasing by only ∼40% from room temperature to 2 K.

High‐Entropy Interfacial Optimized 3D Nano‐Collector Enables Dendrite‐Free and Ultra‐Stable Lithium Metal Batteries

SusMat, EarlyView.
By integrating a MnNiVCrFe HEA interphase with a 3D NF scaffold, this 3D current collector homogenizes the interfacial electric field and Li+ distribution. This synergistic interphase–structure modification strategy enables uniform lithium nucleation and deposition, thereby suppressing dendrite formation and boosting interfacial stability. Consequently,

Wavefront sensing at a high‐repetition‐rate X‐ray free‐electron laser

Journal of Synchrotron Radiation, EarlyView.
We demonstrate a fast, robust and sensor‐free approach to X‐ray speckle tracking that enables shot‐to‐shot wavefront characterization at high‐repetition‐rate X‐ray free‐electron lasers. Our measurements reveal a hierarchy of wavefront fluctuations indicative of instabilities in the accelerator and beamline optics at the European XFEL.Wavefront ...

Flap Anatomies and Victorian Veils: Penetrating the Female Reproductive Interior

Gender &History, EarlyView.
ABSTRACT This article examines the reappearance in the early nineteenth century of anatomical flapbooks in the context of obstetrical education in Britain, America and France. It asks why liftable paper flaps were reintroduced at this time after their disappearance from medical atlases in the eighteenth century.

Similar or Different? Configurations of Authenticity Across Museum Types

Curator: The Museum Journal, EarlyView.
ABSTRACT Authenticity is traditionally regarded as playing a crucial role in museums, science centers, and memorials. However, despite this fact, authenticity has very different meanings in different (institutional) settings. This complicates shared communications across museum practices.
