Searching for gravitational waves from the Crab pulsar - the problem of timing noise [PDF]

, 2003
Of the current known pulsars, the Crab pulsar (B0531+21) is one of the most promising sources of gravitational waves. The relatively large timing noise of the Crab causes its phase evolution to depart from a simple spin-down model.

Suction-induced habitat selection in sand bubbler crabs [PDF]

Royal Society Open Science, 2019
We show that a decapod crustacean, the sand bubbler crab (SBC) Scopimera globosa, uses suction, which is the tension of moisture in the sediment, to select habitats at normal times and at the time of disaster events, through a range of controlled ...
