Accessory osseous structures such as a carpal boss may sometimes simulate soft tissue masses clinically.
This analysis of 28-years of longitudinal data on the demography and oestrus behaviour of African elephants provides the first step in understanding why elephants sometimes simulate oestrus behaviours.
"It's just an expression, man," he says, and explains that the sex is sometimes simulated.
In his photographs, Richardson often features naked or nearly naked young women, sometimes simulating sexual acts.
In a typical performance he would sing in full voice, breaking up the syllables of a song to accentuate the rhythms and sometimes simulating sobs.

X-rays show a grossly damaged joint and two radiographic patterns can be distinguished: the atrophic pattern, in which there is a prevalence of bone resorption that sometimes simulates a surgical amputation (especially in the upper extremity), and the hypertrophic pattern, in which there are productive phenomena, such as osteophyte formation, sclerosis and joint fragmentation.
Apart from implementations of artificial gene regulatory networks, control mechanisms are sometimes simulated by random boolean networks, multi-layer perceptrons, or continuous time recurrent neural networks.
Populated by drunks, louts and grade-A molesters, this compendium of creepitude embraces (and sometimes simulates) the idiosyncrasies of analog recording with varying degrees of skill and creativity.
