Flexible Direct‐Conversion X‐Ray Detectors: From Emerging Materials to Conformal Imaging

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
This comprehensive review analyzed the performance, challenges, and future directions of four emerging material systems for next‐generation flexible direct‐conversion X‐ray detectors: organic semiconductors, perovskites, metal–organic frameworks, and inorganic metal compounds.

Craniofacial Resection for Advanced Cutaneous Squamous Cell Carcinoma: Results From the 2nd International Collaborative Case‐Series

open access: yesHead &Neck, EarlyView.
ABSTRACT Background Robust outcome data for anterior skull base cutaneous squamous cell carcinoma (cSCC) are limited, particularly as emerging therapies reshape management. We evaluated survival and prognostic factors following craniofacial resection. Methods Retrospective multi‐institutional case‐series (1995–2015) of patients who underwent skull base

Community Voices on the Future of Radiation Belt Research: A Summary of the 2024 GEM Radiation Belt Focus Group Round‐Table Discussion

open access: yesEarth and Space Science
Earth's radiation belts are the regions where highly energetic charged particles are trapped by Earth's magnetic field, posing significant risks to the satellites and other space‐based technologies.

Long‐Term Monitoring of Energetic Protons at the Bottom of Earth’s Radiation Belt

open access: yesSpace Weather, 2021
The energetic particles in the Earth's radiation belt are known to fluctuate over various timescales. Although observations using satellites have been made for more than 50 years, there are few examples of continuous and long‐term observations at low ...

Where Projects Fail: Geospatial Evidence of Delays and Cancellations in Chinese Development Finance

open access: yesJournal of International Development, EarlyView.
ABSTRACT Delays and cancellations can severely undermine the effectiveness of development finance. Yet, little systematic evidence exists on where and why these disruptions occur within the rapidly expanding portfolio of Chinese‐financed development projects in Africa.

Prediction of Energetic Electrons in the Inner Radiation Belt and Slot Region With a Double‐Layer LSTM Neural Network Model

open access: yesSpace Weather
The prediction of high‐energy radiation belt electrons is vital for preventing their damage to satellites. Previous machine learning models mostly predict the fluxes of high‐energy electrons (hundreds of keV to MeV) in the outer radiation belt and slot ...

Lightning-induced neutrons as a possible source of charged particles in the Earth’s inner radiation belt

open access: yesEarth and Planetary Physics
The Van Allen radiation belts are doughnut-shaped zones surrounding Earth, filled with highly energetic charged particles whose sources or loss mechanisms have been investigated for decades. As for the inner belt, cosmic ray albedo neutron decay (CRAND),

Intrafraction motion and impact of margin reduction for MR‐Linac online adaptive radiotherapy for pancreatic cancer treatments

open access: yesJournal of Medical Radiation Sciences, Volume 72, Issue 1, Page 17-24, March 2025.
This analysis included quantification of intrafraction motion in pancreas stereotactic ablative radiotherapy treated on the MR‐Linac, leading to the development of adjusted (PTV) margins. Intrafraction motion indicated an average target displacement of 1–3 mm, resulting in an adjusted PTV margin of 2 mm in the right–left and superior–inferior ...

From Rare to Recurrent: Intensifying Hot–Dry Extremes Across Romania

open access: yesInternational Journal of Climatology, EarlyView.
Romania has undergone a marked shift toward more frequent and spatially extensive compound hot–dry months since the 1990s, with persistent hotspots in the eastern Moldavian Plateau and the lower Danube–Bărăgan–Black Sea lowlands and comparatively buffered conditions at higher elevations.
