Phase Field Failure Modeling: Brittle‐Ductile Dual‐Phase Microstructures under Compressive Loading

Advanced Engineering Materials, Volume 28, Issue 17, 9 September 2026.
The approach by Amor and the approach by Miehe and Zhang for asymmetric damage behavior in the phase field method for fracture are compared regarding their fitness for microcrack‐based failure modeling. The comparison is performed for the case of a dual‐phase microstructure with a brittle and a ductile constituent.

Transient Charging of Mixed Ionic‐Electronic Conductors by Anomalous Diffusion

Advanced Materials, Volume 38, Issue 51, 11 September 2026.
This article explores charge transport in mixed ionic‐electronic conductors (MIECs) through electrochemical impedance spectroscopy and transient current analysis. Focusing on PEDOT:PSS, WO3, and n‐doped PBDF, it uncovers the impact of anomalous diffusion via fractional modeling. The study reveals key correlations that deepen understanding and guide the

The quantum connection, Fourier-Laplace transform, and families of $A_{\infty }$-categories

Inventiones mathematicae
Take a closed monotone symplectic manifold containing a smooth anticanonical divisor. The quantum connection on its cohomology has singularities at zero and infinity (in the quantum parameter). At zero it has a regular singular point, by definition. We show that the singularity at infinity is of unramified exponential type.

Nanodiamonds as Bioactive Platforms to Modulate Microbial, Mammalian, and Vertebrate Systems

Advanced NanoBiomed Research, Volume 6, Issue 9, September 2026.
Nanodiamonds (NDs) are biocompatible and antibacterial nanomaterials that support mammalian cell growth while inhibiting bacterial pathogens. NDs showed strong antibacterial activity, with Escherichia coli being more sensitive than Staphylococcus aureus. At 10 mg/mL, both bacteria exhibited ~8% viability.

Generation of SH-type waves in layered anisotropic elastic media

International Journal of Mathematics and Mathematical Sciences, 1979
A study is made of the generation of SH-type waves at the free surface of a layered anisotropic elastic medium due to an impulsive stress discontinuity moving with uniform velocity along the interface of the layered medium.

Ab Initio Path Integral Monte Carlo Study of the 2D Uniform Electron Liquid at Finite Temperatures: Structural Properties, Density Response and Roton‐Type Excitation

Annalen der Physik, Volume 538, Issue 9, September 2026.
Path integral Monte Carlo simulations are used to simulate the 2D electron gas over a broad range of densities and temperatures with very high accuracy. These results constitute a rigorous benchmark for other methods and approximations and uncover the existence of a roton‐type feature in the dynamic structure factor at strong electronic coupling ...

Measuring the error of dynamic hedging: a Laplace transform approach [PDF]

We compute the expected value and the variance of the discretization error of delta hedging and of other strategies in the presence of proportional transaction costs.

Inverse‐consistent deformable image registration to propagate biomechanical constraints for online adaptive radiotherapy

Medical Physics, Volume 53, Issue 9, September 2026.
Abstract Background Accurate motion estimation remains a key challenge in adaptive radiotherapy (ART). Voxel‐wise accuracy is required, as registration errors can compromise the treatment quality. Locally constrained image registration is a promising technique to further improve ART treatment, but relies heavily on quick and accurate delineations of ...

Advanced Electrospun Nanofiber Epidermal Electronics for Electrophysiological Monitoring: From Conformal Interfaces to Multimodal Closed‐Loop Systems

Rare Metals, Volume 45, Issue 9, September 2026.
ABSTRACT Epidermal bioelectronics is a transformative technology for continuous health monitoring and human‐computer interaction. However, the mechanical and physiological mismatch at the skin–device interface limits its long‐term application. Electrospun nanofiber membranes (ENMs), with their unique three‐dimensional hierarchical porous network and ...

A Detailed and Comprehensive Account of Fractional Physics‐Informed Neural Networks: From Implementation to Efficiency

Artificial Intelligence for Engineering, Volume 2, Issue 3, Page 251-264, September 2026.
Caputo‐based fPINNs accurately solve fractional ODEs and PDEs while exposing an accuracy–cost trade‐off driven by the history‐dependent fractional derivative. Temporal collocation and shorter time windows are the most effective strategies for improving early‐time accuracy without unnecessary spatial refinement.
