Beamstop-free small-angle X-ray scattering for multiscale structure measurement of high-energy-density plasma

The advent of free-electron lasers has enabled in-situ small-angle X-ray scattering (SAXS) measurements of laser-produced high-energy-density plasma at solid density, with nanometer- and femtosecond-scale resolution. Such plasmas generally exhibit gentle density gradients, which...

Lightning talk presentation at EOSC Symposium 2026. The PPTX file here labelled "embed screen" contains a screencast video in one slide; the other PPTX file also contains audio and video for the entire presentaiton. The PDF file contains no video or audio. Video is also available...

Episodic isolation of the Arctic Mediterranean from the North Atlantic during late Pleistocene glacials

Abstract It has been proposed that the Arctic Ocean and Nordic Seas (together referred to as the “Arctic Mediterranean” - AM) were not only covered by a thick ice shelf during past Pleistocene glaciations 1 but also filled with freshwater 2 implying a disconnection from the North...

ALD of Tantalum and Titanium Phosphates Using Tris(dimethylamino)phosphine

Abstract Atomic layer deposition (ALD) of metal phosphates is increasingly explored for energy applications, yet the mechanisms governing phosphorus incorporation remain poorly understood. In this work, we introduce two novel ALD processes for amorphous tantalum phosphate and tit...

Sub-nanosecond structural dynamics of the martensitic transformation in Ni-Mn-Ga

Abstract Martensitic transformations drive many emerging applications, ranging from actuation and mechanocaloric refrigeration to thermoelastic energy harvesting. All these applications benefit from faster transformations. However, systematic investigations of the fast dynamics a...

Evaluating Gemma 3 27B for local undergraduate physics tutoring

Abstract Physics education research has developed a range of student-centered approaches that emphasize conceptual understanding and problem solving, creating interest in whether large language models (LLMs) can provide complementary, on-demand tutoring support. Locally deployabl...

Durable treatment response to Trastuzumab deruxtecan in two patients with recurrent grade III anaplastic ependymoma

Abstract Background Anaplastic ependymoma is a rare and aggressive central nervous system malignancy for which effective systemic treatment options are limited. Trastuzumab deruxtecan (T-DXd), an antibody–drug conjugate targeting human epidermal growth factor receptor 2 (HER2), h...

Host–Dopant Engineering of Ce 4+ ‐Dominant Y 3 (Al,Ga) 5 O 12 :Ce,Mg Scintillators for High‐Performance X‐Ray Imaging

ABSTRACT Fast scintillators are essential for advanced X‐ray imaging and time‐of‐flight techniques. Although stabilizing Ce 4+ ions in garnet hosts is an effective strategy for suppressing the afterglow and accelerating scintillation, it often introduces quenching pathways that r...

Quantum effects in plasmas

The year 2025 has been designated by UNESCO as the International Year of Quantum Science and Technology. One hundred and twenty-five years ago, Max Planck's discovery of radiation quanta started the quantum era, and 100 years ago, quantum mechanics was developed by Schrödinger, H...

High-content image-based screening reveals vaccinia virus membrane proteins as potential regulators of LC3 lipidation

Autophagy is a catabolic process used for the degradation of organelles and proteins, and it also functions as a cellular defense mechanism, known as xenophagy, during infection. Vaccinia virus (VACV), the prototypic poxvirus, replicates exclusively in the cytoplasm of host cells...

Early liver parameter increase after transjugular intrahepatic portosystemic shunt (TIPS): hepatic vascular risk factors and development of an exploratory prediction model

Abstract Purpose To investigate early laboratory changes following Transjugular Intrahepatic Portosystemic Shunt (TIPS) and their associations with hepatic vessel diameters. Additionally, to develop a model to predict patients at high-risk for excessive liver parameter increase....

The Second Nitrogen Fits: Development of Diazine-Based Macrocyclic Chelators to Stably Bind Radionuclides Used in Targeted Alpha Therapy

Abstract Identifying suitable chelators for 212Pb, 223Ra, and 225Ac and their diagnostic counterparts 131Ba, 133La, and 203Pb remains one of the major challenges in the development of radiopharmaceuticals for targeted alpha therapy. Four novel macrocyclic chelators containing the...

Ferroelectric Thin‑Film Polarization‑Sensitive Photodetector Based on the Plasmon‑Enhanced Bulk Photovoltaic Effect

ABSTRACT Polarization‑sensitive photodetection is critical for advanced imaging, optical communication, and medical diagnosis technologies. Although detectors based on low‐symmetry metasurfaces or two‐dimensional materials have been widely investigated, they generally suffer from...
