Supersampled Scanning Transmission X‐Ray Microscopy for High‐Resolution Vibration‐Independent Time‐Resolved Imaging

Small, EarlyView.
ABSTRACT Scanning transmission x‐ray microscopy (STXM) is a nanoscale imaging technique that can utilize several powerful contrast mechanisms for the quantitative mapping of chemical and physical materials properties. Spatial resolutions down to 7 nm at the soft x‐ray energy range have been demonstrated.

A real‐time correction method for sample drift in STXM based on Fourier transform image registration

Journal of Synchrotron Radiation, EarlyView.
This study proposes an online drift‐correction method for scanning transmission X‐ray microscopy that integrates Fourier‐transform image registration with laser‐interferometer feedback, suppressing sample drift in a 100‐image stack scan from over 1 mm to below 120 nm and thereby eliminating redundant scan area while markedly enhancing experimental ...

UC2‐ESP: A general‐purpose framework for open‐source microscopy control

Journal of Microscopy, EarlyView.
Abstract Building the optical setup for investigating biological questions comes with challenges. A major such challenge is setting up and synchronizing the control of multiple hardware components such as stages, cameras and lasers. With UC2‐ESP, we present a low‐cost electronics system powered by the ESP32 microcontroller (∼$10), designed as an ...

Enhancing Reference Tracking in Induction Motor Drives: A Hybrid Model Predictive Control and Artificial Neural Network Approach

International Journal of Robust and Nonlinear Control, Volume 36, Issue 14, Page 6719-6738, 25 September 2026.
ABSTRACT Induction motors (IMs) are widely used in industry for their robustness and cost‐effectiveness, yet their nonlinear and multivariable dynamics pose significant challenges for high‐performance speed control. Model Predictive Control (MPC) is a well‐established solution but suffers from limitations related to model accuracy and parameter ...
