Application of the Boson-Fermion Hybrid Representation: Why is Spin-Polarized Atomic Hydrogen a Bosonic System?
In the previous talk by Wu1, a formalism known as the boson-fermion hybrid representation (BFHR) was proposed. The BFHR was utilized to form a theoretical foundation of the nuclear field theory2 (NFT). However, o...

Primordial nucleosynthesis and scale-covariant cosmology
The scale-covariant theory of gravitation, which was proposed by Canutoet al. (1977), assumes that gravitational and atomic units are related by a scalar function of space-time. The cosmology based on this theory...
