If availability is unaccounted for, survival and detection probability estimates will be biased.
The ability to entrain circadian rhythms to food availability is important for survival.
Using a cost-minimization model for Sweden, accounting for embryo availability, survival following thawing, and patient dropout, we simulated patients individually for up to three cycles.
However, many species have also evolved mechanisms for the entrainment of circadian rhythms to other environmental cues important for survival, such as food availability.
For example, tissue availability, graft survival, immunogenicity, tumorigenicity, and varying levels of cell migration, differentiation, and integration into functional circuits and the microenvironment provided by sclerotic tissue all contribute to the efficacy of transplanted cells.
As neurons rely on neurotrophins for survival, any alterations in the availability of such molecules could result in irreparable damage.
This is suggested to increase the availability of RNAP for activation of genes required for survival under various stressful conditions [ 7].
In oligotrophic environments, where nutrient availability is sporadic, the ability to rapidly accumulate polyphosphate for survival of Pi-limitation would be favorable.
This important "feedback" mechanism may help transformed cells to escape the apoptotic cascade, allowing for survival during limited glucose and oxygen availability.
When the amount of resources needed for survival is relatively small (compared to mean resource availability) most individuals will survive.
