Quantitative analysis of the Landis method.
Muscarella LF, Pathak AS, Takashima S, Noordergraaf A. Muscarella LF, et al. Microvasc Res. 1993 Jan;45(1):46-64. doi: 10.1006/mvre.1993.1005. Microvasc Res. 1993. PMID: 8479341 Review.
Each of the techniques assumes that the capillary is a uniformly cylindrical indistensible tube. Since recently obtained experimental data have demonstrated that the capillary is compliant, a distributed mathematical model of the capillary was developed to reveal th …

Wave transmission and input impedance of a model of skeletal muscle microvasculature.
Frasch HF, Kresh JY, Noordergraaf A. Frasch HF, et al. Ann Biomed Eng. 1994 Jan-Feb;22(1):45-57. doi: 10.1007/BF02368221. Ann Biomed Eng. 1994. PMID: 8060026
Input impedance displays a similar form under all conditions: Magnitude is a monotonically decreasing function of frequency, and phase decreases from 0 to approximately -45 degrees. Consideration of the characteristic impedance of a microvessel leads to modif …
