KG-oscillators in Eddington-inspired Born-Infeld gravity: Wu-Yang magnetic monopole and Ricci scalar curvature effects by Omar Mustafa

“…We investigate the Klein-Gordon (KG) oscillators in a global monopole (GM) spacetime in Eddington-inspired Born-Infeld (EiBI) gravity and a Wu-Yang magnetic monopole (WYMM). We discuss the gravitational effects in the presence of Ricci scalar curvature R=Rυυ. …”

Structural restoration of a historic palace in Italy by Paolo Foraboschi

“…The paper begins by presenting, in broad terms, the full extent of the structural work and then focuses on the static strengthening of the masonry vertical load-bearing elements, for which it proposes a tailored structural solution directed at buildings with vulnerabilities to gravitational loads. The paper offers a detailed analysis of vertical masonry elements, addressing the issue of strength evaluation and stress analysis to predict their structural performance as well. …”

Structure of massive gauge/gravity scattering amplitudes, equivalence theorems, and extended double-copy with compactified warped space by Yanfeng Hang, Wei-Wei Zhao, Hong-Jian He, Yin-Long Qiu

“…We present systematic formulations of the gauge theory equivalence theorem (GAET) and the gravitational equivalence theorem (GRET) for warped KK theories in R ξ gauge, where the GAET connects the scattering amplitudes of longitudinal KK gauge bosons to that of the corresponding KK Goldstone bosons and the GRET connects the scattering amplitudes of KK gravitons of helicity-zero (helicity-one) to that of the corresponding gravitational scalar (vector) KK Goldstone bosons. …”
