Handbook of best practice and standards for 2D+ and 3D imaging of natural history collections

open access: yesEuropean Journal of Taxonomy, 2020
Digitising a collection is key to make it last even after the physical objects are no longer available. Almost all of the techniques currently available to digitise a natural history collection in 2D+ and 3D are listed herein.

Time Delay Induced Death in Coupled Limit Cycle Oscillators [PDF]

open access: yes, 1998
We investigate the dynamical behaviour of two limit cycle oscillators that interact with each other via time delayed coupling and find that time delay can lead to amplitude death of the oscillators even if they have the same frequency.
