Widely Tunable SNAP Microresonators Induced at the Optical Fiber Intersections

open access: yesNanophotonics, Volume 15, Issue 22, 25 November 2026.
Optical fiber intersections create high‐Q microresonators with a widely tunable free spectral range. The theory reveals how inter‐fiber coupling localizes whispering‐gallery modes and how dramatically small fiber curvature reshapes the resonator spectrum.

From Hyperelastic Physics‐Augmented Neural Networks to Fortran User Materials: Standalone Implementation and Computational Performance in Explicit Dynamics

open access: yesInternational Journal for Numerical Methods in Engineering, Volume 127, Issue 21, 15 November 2026.
ABSTRACT Data‐driven material modeling techniques have gained significant attention due to their ability to capture the complex constitutive behavior beyond the limitations of classical material models. Physics‐augmented neural networks (PANNs), which incorporate physical restrictions into their architecture, combine the flexibility of machine learning

Subwavelength Topology Optimization With Feature‐Mapping

open access: yesInternational Journal for Numerical Methods in Engineering, Volume 127, Issue 21, 15 November 2026.
ABSTRACT Acoustic topology optimization has been extensively studied since the earliest developments of structural optimization, and substantial progress has been made in the design of acoustic devices. More recently, wave‐focusing applications have attracted growing interest.

Multi‐system evaluation of baseline‐referenced gray scale CNR profile deviation for phantom‐based ultrasound quality assurance

open access: yesJournal of Applied Clinical Medical Physics, Volume 27, Issue 11, November 2026.
Abstract Background Phantom‐based ultrasound quality assurance (QA) commonly incorporates qualitative image assessment, whereas robust baseline‐referenced quantitative indicators for routine monitoring across multiple systems remain limited. Purpose To investigate whether controlled transducer surface acoustic shielding produces measurable baseline ...

Observer‐Based Adaptive Event‐Triggered Tracking Control for Fuzzy TS Systems With Premise Mismatch

open access: yesInternational Journal of Adaptive Control and Signal Processing, Volume 40, Issue 11, Page 2160-2176, November 2026.
This paper presents an adaptive logistic event‐triggered observer‐based tracking controller for Takagi‐Sugeno fuzzy systems under constrained inputs and network delays. Leveraging a hybrid LMI and Secretary Bird Optimization approach, this strategy significantly minimizes communication overhead and computational burden while ensuring optimal reference ...
