We have observed dwarf nova oscillations (DNOs) in OY Car during outburst, down through decline and beyond; its behaviour is similar to what we have previously seen in VW Hyi, making it only the second dwarf nova to have DNOs late in outburst that continue well into quiescence. There are also occasional examples of DNOs in deep quiescence, well away from outburst – they have properties similar ...

Suppose that cells divide with rate l, die with rate d, become quiescent with rate α, and “wake up” from quiescence with rate β. We will refer to parameters α and β as quiescence parameters. Note that the “amount of quiescence” in the colony correlates positively with α and negatively with β. Let us denote by i the number of cycling cells and by j the number of quiescent cells. The system’s sta...
Many organisms enter quiescence in response to adverse environmental factors. Here, we show that L1 stage C. elegans entered a quiescent state after 3hours exposure to diacetyl in which movement and growth stopped for hours to days after odorant removal. Entry into quiescence was dependent on neurons affected by the osm-3 mutation, and by AWA neurons. Conversely, AWB/AWC neurons, the guanylyl c...
Prolonged exit from quiescence by hematopoietic stem cells (HSCs) progressively impairs their homeostasis in the bone marrow through an unidentified mechanism. We show that Rb proteins, which are major enforcers of quiescence, maintain HSC homeostasis by positively regulating thrombopoietin (Tpo)-mediated Jak2 signaling. Rb family protein inactivation triggers the progressive E2f-mediated trans...
