Concept, Tests, and Optimum Design of Novel Negative Stiffness Friction Dampers for Seismic Protection of Long‐Span Bridges

open access: yesEarthquake Engineering &Structural Dynamics, Volume 55, Issue 11, Page 2719-2741, September 2026.
ABSTRACT Viscous dampers (VDs) are widely used to mitigate the excessive responses of long‐span bridges. However, VDs face some intricate challenges in engineering practices, including high damping coefficient requirement, potential base shear amplification and tremendous damping force under high velocity. To address these issues, this study develops a

Squeezed‐State Semi‐Device‐Independent Quantum Randomness Generation

open access: yesAdvanced Quantum Technologies, Volume 9, Issue 9, September 2026.
Semi‐device‐independent quantum randomness is certified for squeezed‐coherent binary states using only their trusted overlap and the observed homodyne error. Including the deterministic extremes of the full binary‐qubit POVM gives the correct closed‐form Shannon rate.

Lightweight Metal–Polymer Interpenetrating Phase Composites for Mechanical Reinforcement and Absorption‐Dominant Electromagnetic Interference Shielding

open access: yesRare Metals, Volume 45, Issue 9, September 2026.
ABSTRACT The pursuit of multifunctional lightweight materials with electromagnetic interference (EMI) shielding of low reflection, programmable architecture, and robust mechanical performance presents both significant opportunities and challenges. In this work, aluminum (Al)‐alloy lattice with 90% porosity was designed and fabricated using additive ...

Non‐Elliptical Dimension Reduction in Survival Regression

open access: yesStat, Volume 15, Issue 3, September 2026.
ABSTRACT Sufficient dimension reduction (SDR) in survival regression aims to identify low‐dimensional structures that preserve the relationship between survival time and predictors. Classical SDR methods, such as sliced inverse regression (SIR), rely on strong assumptions such as linearity, constant variance and coverage conditions, which are often ...
