Quantum Reduced Loop Gravity [PDF]
Proceedings of Frontiers of Fundamental Physics 14 — PoS(FFP14), 2016 Quantum Reduced Loop Gravity provides a promising framework for a consistent characterization of the early Universe dynamics. Inspired by BKL conjecture, a flat Universe is described as a collection of Bianchi I homogeneous patches. The resulting quantum

Quantum-reduced loop gravity: Cosmology [PDF]
Physical Review D, 2013 We introduce a new framework for loop quantum gravity: mimicking the spin foam quantization procedure we propose to study the symmetric sectors of the theory imposing the reduction weakly on the full kinematical Hilbert space of the canonical theory.

The Three-Dimensional Body Center of Mass at the Workplace under Hypogravity
Bioengineering, 2023 The center of mass dynamics of the seated posture of humans in a work environment under hypogravity (0 < g < 1) have rarely been investigated, and such research is yet to be carried out.
