A QUBO Formulation for Multi‐Material Topology Optimization With Quantum Annealing

International Journal for Numerical Methods in Engineering, Volume 127, Issue 16, 30 August 2026.
ABSTRACT Multi‐material topology optimization (MMTO) seeks the optimal distribution of multiple materials within a given design domain to maximize structural performance. However, due to the high complexity of the solution space, MMTO problems are often trapped in local optima. To address this issue, a quantum annealing‐based MMTO framework is proposed.

Knowledge‐distilled diffusion models for improving cone‐beam CT image quality with meta‐learning under imbalanced data

Medical Physics, Volume 53, Issue 8, August 2026.
Abstract Background Adaptive radiation therapy (ART) relies on daily cone‐beam CT (CBCT), yet its limited image quality hinders accurate dose calculation, particularly under substantial anatomical changes. Purpose To overcome the clinical challenge of scarce paired planning CT (pCT) data versus abundant unpaired CBCTs, we propose a framework driven by ...

Exceptional Multifunctional Performance Enabled by a Network Architecture in Additively Manufactured NiFe‐Based Soft Magnetic Alloys

Rare Metals, Volume 45, Issue 7, July 2026.
ABSTRACT The mechanical properties and corrosion resistance of traditionally as‐cast soft magnetic Ni‐50Fe alloys often fail to meet current application requirements. To address this limitation, this study employed direct energy deposition (DED) to fabricate two kinds of soft magnetic alloys: Ni‐50Fe and Ni‐48.5Fe‐1.5Cu‐1.5Ti.
