Explicit and high-precision period approximations for the circular Sitnikov restricted four-body problem

Abstract This brief note presents an explicit analytical approximation to the period of the circular Sitnikov restricted four-body problem. The proposed approximation achieves superior accuracy and greater algebraic compactness compared to existing analytical approximations acros...

Experimental Investigation of Flexural Performance of Prestressed Precast Hollow-Core Slabs with Foam Inserts and Wet Joints

This study introduces a novel prestressed precast hollow-core slab system with integrated polystyrene foam inserts and a spliced design utilizing cast-in-place wet joints, aiming to resolve the inherent trade-off between self-weight reduction and load-bearing capacity in precast...
