To understand nuclear decay equations. How to measure the activity of radioactive sources. Spontaneously means that the process of radioactive decay can not be speeded up or slowed down by physical ...

“The mass and the antiparticle nature of neutrinos can be studied by measuring the radioactive beta and double-beta decays of ...

We address decay properties of strong solutions of the Navier-Stokes equation. Obtained space-time decay rates agree with those of the heat equation. This improves earlier results by sharpening the ...

We investigate the decay properties of the mass $M\left( t \right) = {\smallint _{{R^N}}}u\left( {\cdot,t} \right)dx$ of the solutions of a fractional diffusion ...
