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

Earthquake 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

Structure Formation in Dairy Cheese and Plant‐Based Cheese Analogues: A Review

Sustainable Food Proteins, Volume 4, Issue 3, September 2026.
In this review, structure formation in dairy cheese and plant‐based cheese analogues is analyzed following a multi‐length scale perspective. Particular emphasis is placed on the distinction between bottom‐up assembly, characteristic of natural dairy cheese, and top‐down structuring, typical of processed cheese and cheese analogues.
