Cell differentiation ultimately proceeds as a response to signals from the extracellu- lar microenvironment. If the cells are competent, that is, if they carry the correspond- ing receptors and signal transduction pathways, they can be triggered in the commit- ment state.

Reducing AC-termination to termination
1998We present a new technique for proving AC-termination. We show that if certain conditions are met, AC-termination can be reduced to termination, i. e., termination of a TRS S modulo an AC-theory can be inferred from termination of another TRS R with no AC-theory involved. This is a new perspective and opens new possibilities to deal with AC-termination.

Self-termination of the terminator
Nature Immunology, 2008The protein kinase NIK is regulated by a complex of ubiquitin ligases that destroys it. When NIK-activating receptors are triggered, the ubiquitin ligase complex self-destructs.

Is it Time to Terminate the Traditional Terminal Value?
SSRN Electronic Journal, 2020All corporate valuation models rely on very long forecasts of free cash flows. The only question is whether those forecasts are accounted for explicitly by using an extended valuation model or implicitly in an estimate of the terminal value after an explicit short-term forecast period of five to ten years.

Aging, Terminal Decline, and Terminal Drop
Journal of Gerontology, 1976Data from a 20-year longitudinal study of persons over 60 were analyzed by step-wise multiple regression to test for declines in function with age, for terminal decline (linear relationship to time before death), and for terminal drop (curvilinear relationship to time before death). There were no substanial terminal drop effects.
