An induction heating system for in situ X‐ray diffraction imaging: design, simulation and application to dislocation dynamics in semiconductors

open access: yesJournal of Synchrotron Radiation, EarlyView.
This work presents a compact induction heating system for time‐resolved in situ X‐ray diffraction imaging. The system enables contact‐free volumetric heating up to approximately 1600°C and provides flexible operation in different operating modes. Its performance is demonstrated through representative diffraction imaging experiments.We present a compact

Story2Board: A Training‐Free Approach for Expressive Visual Storytelling

open access: yesComputer Graphics Forum, EarlyView.
Abstract We present Story2Board, a training‐free framework for expressive storyboard generation from natural language. Existing methods narrowly focus on subject identity, overlooking key aspects of visual storytelling such as spatial composition, background evolution, and narrative pacing.
