Based on an extended time-space symmetry, a cylindrical model of gravitational geometrical dynamics with two time-like extra-dimensions leads to a microscopic geodesic description of the curved space-time. Due to interaction of a Higgs-like cosmological potential with individual space-time fluctuations, the original time-space symmetry is spontaneously broken, inducing a strong time-like curvature and a weak space-like deviation curve. As a result, the basic Klein-Gordon-Fock equation of a free massive elementary particle was derived, which implies a duality between the quantum mechanics equation and a microscopic geodesic description in the frame of general relativity. Consequently, Heisenberg inequalities are determined explicitly by the space-time curvatures. Moreover, extending curvatures to higher time-like dimensional hyper-spherical surfaces than one of the basic common cylindrical configuration, we found reasonable mass ratios of all charged leptons and succeeded to fix the number of their generations to be three. Following to concepts of the standard cosmological model, a possible experimental verification of mass ratio variation is proposed.

In this report, we study the effect of silver nanowires (AgNws) dimension to electrical properties of rGO/AgNws hybrid. The alteration of these electrical properties leads the difference of ammonia sensibility of the rGO/AgNws hybrid based sensing devices. When the rGO is accompanied by AgNws of different sizes from ∼ 500 nm to > 10 µm, the ammonia sensitivity of these hybrids change from 60% to 340% alteration compared with the bare rGO material.

The dependence upon atmospheric pressure of the cosmic muon flux in Hanoi has been measured to be -1.47± 0.50 permil per mbar in agreement with expectation from a naive estimate. The dependence over ground temperature is observed to largely reflect the correlation existing between temperature and pressure. Once the effect of this correlation is removed a smaller, barely significant temperature dependence of -0.57± 0.34 permil per °C subsists.
