We prove a Theoretical result which relates phase-lag to the error constant of a numerical method for periodic problem y'' = f(x, y).

The well-known two-step fourth-order Numerov method was shown to have better interval of periodicity when made explicit, see Chawla (1984). It is readily verifiable that the improved method still has phase-lag of order 4. ...

Ecological theory predicts that the success of exotic plants in new environments depends on a combination of ecological attributes. Requirements for germination and seedling traits are the main components in the regenerative ...

The lag times (lambda) of Geobacillus stearothermophilus single spores were studied at different storage temperatures ranging from 45 to 59 degrees C using the Bioscreen C method. A significant variability of lambda was ...

Arboreal squirrels of the Asiatic genus Callosciurus have shown high likelihood of establishment from few released animals, in particular, C. erythraeus has established wild populations in Argentina, Belgium, France, Hong ...
