Physics Today, 1975
A pendulum can be stopped by a single impulse of the right magnitude, delivered at the proper time; started again, its phase will have changed. A biological oscillation, although it is a vastly more complicated phenomenon, can likewise be arrested by a single stimulus of a definite strength delivered at the proper time.

Phase locking of biological clocks
Journal of Mathematical Biology, 1982Radial isochron clocks (RICs) and their response to external signals and coupling with other RICs are studied. RICs are derived as phase approximations to self-sustained oscillators. Their response to single impulses (phase resetting) and to repetitive impulses is determined. This response may be harmonic or chaotic.

Epigenetic clocks and allostatic load reveal potential sex-specific drivers of biological ageing.
The journals of gerontology. Series A, Biological sciences and medical sciences, 2019Allostatic Load (AL) and epigenetic clocks both attempt to characterise the accelerated ageing of biological systems, but at present it is unclear whether these measures are complementary or distinct.

Integration of biological clocks and rhythms.
Comprehensive Physiology, 2012Animals, plants, and microorganisms exhibit numerous biological rhythms that are generated by numerous biological clocks. This article summarizes experimental data pertinent to the often-ignored issue of integration of multiple rhythms.

Do men have biological clocks that affect their hormone levels, fertility, and the genetic quality of their sperm? Women can no longer be viewed as solely responsible for age-related fertility and genetic problems. The effects of andropause and advanced paternal age on fertility and offspring are still under investigation. Further research is needed to
