Prime Conch Geometry and Riemann Zeta Zero Analysis Based on Modulo-210 Periodic Vortex Topology (PDSM Framework)

Abstract: 1. This paper constructs the Prime Vortex Dynamic System (PDSM) and establishes an eight-ridge prime conch topological structure constrained by dual modulo-30 and modulo-210 periodic boundaries, breaking the coarse-grained limitations of traditional prime geometric mode...

Damping performance of rubberised double chip seals

Double chip seals provide skid resistance and durability but offer limited vibration damping. This study evaluated rubberised double chip seals using tire-drop and hammer-impact tests and a unified vibration attenuation coefficient. AC-13 asphalt concrete, single chip seals and t...
