A period of rapidly accelerating expansion is expected in the early Universe implemented by a scalar field slowly rolling down along an asymptotically flat potential preferred current data. In this paper, we point out that picture cosmic inflation with could emerge from Palatini quadratic gravity adding matter such way to break local gauged conformal symmetry both kinetic and terms.

This paper analyzed the asymmetric flat rolling process of square section bars by testing experiments and finite element simulation methods. The impacts rate roll diameter, decrease in altitude, rotational speeds rolls on width cross-section curl radii at leaving point deformation for brass aluminum bar materials were investigated. Furthermore, was simulated using ABAQUS commercial software. A ...
