Post-extra systolic potentiation: influence of calcium and verapamil in rat and rabbit hearts.
Kerker JP, Ruigrok TJ, Nieuwenhuijs JH, Borst C, Meijler FL. Kerker JP, et al. Eur Heart J. 1985 Jun;6(6):532-8. doi: 10.1093/oxfordjournals.eurheartj.a061899. Eur Heart J. 1985. PMID: 2412821
Although contractions were restored to control level by an increase in extra-cellular calcium they were still abnormal in the sense that PESP could not be elicited. The excitation-contraction (e-c) uncoupling due to low calcium perfusion could be counteracted by paired sti …

Resonances in electromagnetic scattering by objects with negative absorption.
Kerker M. Kerker M. Appl Opt. 1979 Apr 15;18(8):1180-9. doi: 10.1364/AO.18.001180. Appl Opt. 1979. PMID: 20208905
This is a numerical study of electromagnetic scattering by particles exhibiting negative absorption, i.e., with refractive index m = n(1 + kappai), where the time dependence is exp(+iomegat). ...
