Theories of gravity that obey the Weak Equivalence Principle have same Parametrised Post-Newtonian parameter $\gamma$ for all particles at energies. The large Shapiro time delays extragalactic sources allow us to put tight constraints on differences in between photons different frequencies from spectral lag data, since a non-zero $\Delta \gamma$ would result frequency-dependent arrival time. ma...

The Portevin–Le Chatelier effect in an AlCu/Al2O3 composite with a large volume fraction (60%) of ceramic particles is investigated from numerical point view using strain-ageing visco-plastic material model for the metallic matrix and several different finite element meshes based on real microstructures. Even this very fraction, some serrations are observed experimental tensile stress/strain cu...

Quantum phenomena do not violate the principle of locality-a new interpretation with physical consequences-Abstract A new interpretation of nonrelativistic quantum mechanics explains the violation of Bell's inequality by maintaining realism and the principle of locality.

In the minimal standard model (SM) with mν = 0, the 3 lepton numbers Le, Lμ, and Lτ are separately conserved. However, given the present neutrino-oscillation data, which imply that neutrinos have mass and mix with one another, the only conserved lepton number is L = Le+Lμ+Lτ if mν is Dirac, and (−1)L if mν is Majorana. As a result, lepton flavor violation must occur in τ decays, which may be cl...
