  2. Power (statistics) - Wikipedia

    en.wikipedia.org/wiki/Power_(statistics)

    For example, a careful power analysis can tell you that 55 pairs of normally distributed samples with a correlation of 0.5 will be sufficient to grant 80% power in rejecting a null that the correlation is no more than 0.2 (using a one-sided test, α = 0.05).

    Some specify which end of the filament is to be powered by the positive side of the filament power supply (usually a battery). All have glass bodies that measure from 0.285 to 0.400 inches (7.2 to 10.2 millimetres) wide, and from 1.25 to 2.00 inches (32 to 51 millimetres) in overall length. 1C8 – Pentagrid converter, R8

  5. List of particles - Wikipedia

    en.wikipedia.org/wiki/List_of_particles

    The graviton must be a spin-2 boson because the source of gravitation is the stress–energy tensor, a second-order tensor (compared with electromagnetism's spin-1 photon, the source of which is the four-current, a first-order tensor). Additionally, it can be shown that any massless spin-2 field would give rise to a force indistinguishable from ...

    The lattice has vertex types (1 ⁄ 2)(3 3,4 2) + (1 ⁄ 2)(3,4,6,4), while the dual lattice has vertex types (1 ⁄ 15)(4 6)+(6 ⁄ 15)(4 2,5 2)+(2 ⁄ 15)(5 3)+(6 ⁄ 15)(5 2,4). The critical point is where the longer bonds (on both the lattice and dual lattice) have occupation probability p = 2 sin (π/18) = 0.347296... which is the bond ...
