Advanced Intelligent Systems, EarlyView.This work develops a CGAN‐based metasurface inverse design method. It adopts an integrated workflow of pixel‐based graphical modeling, simulation, and GAF transform for automatic, batch metasurface dataset construction. With a U‐Net architecture, the CGAN generates high‐resolution, high‐fidelity metasurface structures. EIT verification achieves over 90%

MELD score predicts outcomes in patients with advanced heart failure: A longitudinal evaluation
ESC Heart Failure, Volume 12, Issue 2, Page 839-847, April 2025.Abstract Aims Advanced heart failure (AHF) is characterized by recurrent episodes of haemodynamic instability and frequent hospitalizations, leading to a progressive decline in quality of life and high mortality rates. The objectives of this study were to evaluate the effect of the model for end‐stage liver disease (MELD) score and its variations in ...

Combined Metasurface and Metamaterial Passive Transmit Lens and Receive Array for 3 T
Magnetic Resonance in Medicine, EarlyView.ABSTRACT Purpose Metasurfaces (MSs) and metamaterials (MMs) can reduce transmit field nulls caused by wavelength effects at higher MR field strengths. We present a layered MM and MS resonant structure that improves transmit field performance when used as a combined slab (i.e., the metaslab), while also operating as a receive array.
