A Multifaceted Spatial Analysis of Tomb Distribution in Blemmyan Berenike (Eastern Desert of Egypt)
Archaeological Prospection, EarlyView.ABSTRACT This study examines the spatial and visual organisation of tombs in the post–Roman Berenike located in Egypt's Eastern Desert. Archaeological surveys, remote sensing, geophysical methods, excavations and GIS‐based analyses are used for a comprehensive understanding of the spatial patterns and cultural significance behind the positions and ...

Geophysical Monograph Series, Page 263-304., 2021 Exploring the links between Large Igneous Provinces and dramatic environmental impact
An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

Astronomische Nachrichten, EarlyView.ABSTRACT The discovery of radio‐quiet, x‐ray thermally emitting isolated neutron stars (XINSs) in the ROSAT All‐Sky Survey revealed a previously overlooked component of the neutron star population. Advancements in x‐ray instrumentation and the availability of deep, wide‐area optical surveys now enable us to explore XINSs at fainter x‐ray fluxes and ...

iSELECTION: An Instrument to Study the Kinetics of Isomer‐Selected Gas‐Phase Ion‐Molecule Reactions
Chemistry–Methods, EarlyView.Isomer‐specific reactivity is key in cluster chemistry. Herein, it is shown that how combining drift‐tube ion mobility with mass spectrometry enables the derivation of reaction rate coefficients for coexisting C40+$\text{C}_{40}^{+}$ isomers, opening new avenues for studying complex chemical systems ...

Radio interference in the near-earth environment [PDF]
Natural and man-made radio frequency interference (RFI) are potentially serious obstacles to the successful operation of an array of spacecraft used for low frequency (1 to 30 MHz) radio interferometry in the near-earth environment.

Analysis of image formation in optical palpation
Journal of Biophotonics, EarlyView.Optical palpation is an emerging elastography technique that generates images of mechanical stress at the tissue surface, with applications in intraoperative cancer detection. Image formation is simulated using finite element analysis and validated with experiments on silicone phantoms, providing an analysis of trends in detectability, feature ...

MARS: Programmable multipurpose auto‐release system for aquatic observations
Limnology and Oceanography: Methods, EarlyView.Abstract Aquatic biodiversity assessments are often labor‐intensive due to the large size of the equipment and the complex logistics of sea vessel operations. Traditional drift and drop cameras are typically tethered to the surface, causing cable and line clutter on sea vessels.
