Successful Single‐Session Neural Self‐Regulation Through Neurofeedback Varies Between Features

open access: yesHuman Brain Mapping, Volume 47, Issue 11, 01 August 2026.
We demonstrate that the ‘non‐learner’ problem is not a universal personal trait: using an intra‐subject cross‐over design, all participants successfully regulated multiple rhythms despite failing to modulate Theta. We identify distinct learning trajectories, highlighting the importance of frequency specificity in neural self‐regulation.

Advances in Position‐Momentum Entanglement: A Versatile Tool for Quantum Technologies

open access: yesLaser &Photonics Reviews, Volume 20, Issue 15, 7 August 2026.
Position–momentum entanglement constitutes a high‐dimensional continuous‐variable resource in quantum optics. Recent advances in its generation, characterization, and control are reviewed, with emphasis on spontaneous parametric down‐conversion and modern measurement techniques.

Consistent Quadratic Phase Formation in 3D Fast Spin Echo Using Frequency‐Modulated RF Pulses

open access: yesMagnetic Resonance in Medicine, Volume 96, Issue 2, Page 666-681, August 2026.
ABSTRACT Purpose Frequency‐modulated (FM) RF pulses achieve broadband excitation with low RF peak power, which is required in MRI with inhomogeneous magnetic fields. However, the quadratic phase generated with FM pulses makes it difficult to use them in fast spin echo (FSE), because even and odd refocused echoes have different spatial phase profiles ...

Development of an Artificial Intelligence–Driven Three‐Dimensional Reconstruction Model of Renal Vasculature for Surgical Planning in Robot‐Assisted Partial Nephrectomy

open access: yesThe International Journal of Medical Robotics and Computer Assisted Surgery, Volume 22, Issue 4, August 2026.
ABSTRACT Background This single‐centre study aimed to implement and internally validate a deep learning pipeline based on a 3D SegResNet architecture for automatic segmentation of renal vascular structures from contrast‐enhanced CT images, enabling accurate three‐dimensional reconstructions to support surgical planning in robot‐assisted partial ...

Measurements and scaling of X‐ray total scattering from single crystals

open access: yesJournal of Applied Crystallography, Volume 59, Issue 4, Page 1224-1237, August 2026.
A measurement protocol and data reduction workflow are presented for obtaining single‐crystal X‐ray total‐scattering datasets on an absolute scale, capturing both Bragg and diffuse intensities from the same dataset. The study demonstrates consistency between scale factors derived from Bragg refinements and from spherical integration of the total ...

Fully Polarimetric Radar Cross‐Section and High‐Resolution Range Profile Co‐Modulation via Diversely Time‐Modulated Metasurface

open access: yesNanophotonics, Volume 15, Issue 14, 27 July 2026.
A diversely time‐modulated metasurface enables broadband co‐modulation of fully polarimetric radar cross section and high‐resolution range profiles. By integrating anti‐parallel PIN diodes and programmable temporal coding, the platform dynamically redistributes scattering among HH/VV and HV/VH channels, generating tunable target weakening, false ...
