This paper proposes a potentially viable “out-of-the-box” alternative (called “SUSYA”) to the currently known supersymmetry (SUSY) theory variants: SUSYA essentially proposes a new type of seesaw mechanism (SMEC) applicable to all elementary particles (EPs) and named “Z-SMEC”; Z-...

The dynamics of systems in barrier structures is determined by the rate of the fluctuational decay of metastable states in a potential relief. The nature of the decay undergoes a qualitative change with a variation of the temperature. As the temperature decreases, thermal fluctua...

In the field of fluid mechanics, the temperature distribution and the nanoparticles concentration are usually described by singular boundary value problems (SBVPs). Such SBVPs are also used to describe various models with applications in engineering and other areas. Generally, ob...

Vacuum polarization rearranges virtual pairs. This causes the virtual pairs to rigidify in vacuum, reducing the quantum fluctuation energy. The quantum fluctuation energy is a fundamental force of vacuum, as evidenced by the Casimir effect. The change in quantum fluctuation ene...

The compatibility of the strong interaction theory called Quantum Chromodynamics (QCD) with relevant experimental data is critically examined. The clear advantage of the Regular ChargeMonopole Theory over QCD is explained. An analysis of new data provides further support for this...

A new spacetime is isolated and added to the existing spacetime, yielding a pair of co-existing spacetimes, which are four-dimensional inversions of each other. The separation of the spacetimes by the special-relativistic event horizon, compels an interpretation of a pair of symm...
