High‐Resolution 3D Imaging with Tunable Point Cloud Projection Based on Meta‐Device

open access: yesLaser &Photonics Reviews, Volume 20, Issue 2, 22 January 2026.
A meta‐based tunable point cloud projection that enables high‐resolution 3D imaging through a dynamic meta‐device is demonstrated. By adjusting spatial sampling, the system achieves significantly sharper reconstructions while remaining compact. The innovation opens new possibilities for applications such as facial recognition, augmented reality, and ...

A deep‐learning model for one‐shot transcranial ultrasound simulation and phase aberration correction

open access: yesMedical Physics, Volume 53, Issue 1, January 2026.
Abstract Background Transcranial ultrasound is a promising non‐invasive neuromodulation technique with applications, including neuronal activity modulation, blood–brain barrier opening, targeted drug delivery, and thermal ablation. Its ability to deliver focused ultrasound waves to precise brain regions has led to over 50 clinical trials targeting ...

Regional Medium‐Scale Traveling Ionospheric Disturbance Propagation Model Based on BDS GEO Satellites

open access: yesSpace Weather, Volume 24, Issue 1, January 2026.
Abstract Accurate modeling of traveling ionospheric disturbances (TIDs) is essential for characterizing their spatiotemporal variations and mitigating their effects on Global Navigation Satellite System (GNSS) precise positioning. This study develops a regional medium‐scale TID (MSTID) propagation model using BeiDou geostationary orbit (GEO) total ...

Wavelet‐Based Denoising Optimization for Endoscopic Gastric Slow‐Wave Recordings

open access: yesHealthcare Technology Letters, Volume 13, Issue 1, January/December 2026.
This study presents an optimisation of advanced signal processing techniques, tailored to the slow‐wave activation morphology and realistic noise profiles of minimally invasive recordings. Wavelet‐based denoising methods were applied to 12 sets of synthetic signals, derived from human recordings and demonstrated significantly better denoising ...

A high transmission tender X‐ray monochromator employing a matched pair of multilayer grating and mirror

open access: yesJournal of Synchrotron Radiation, Volume 33, Issue 1, Page 63-72, January 2026.
Monochromators based on multilayer gratings can provide a very high throughput on an extended energy range (1 to 5 keV) in the tender X‐ray domain. A multilayer mirror must be associated with the grating to achieve a fixed exit direction. We show how important an accurate modeling of the reflectivity of these two elements is to achieve both an optimal ...

For your eyes too: a new set of images of biological materials from the scientific commissioning of the MOGNO beamline at Sirius

open access: yesJournal of Synchrotron Radiation, Volume 33, Issue 1, Page 170-180, January 2026.
From whole specimens to histological level reconstructions, images derived from 3D synchrotron‐based microtomography (SR‐microCT) have emerged as a tool that is revolutionizing a wide range of biological research. This paper presents the first commissioning results from experiments to image the anatomy of small animals and specimens from zooarchaeology
