Название: Number fluctuation analysis of random locomotion. Statistics of a Smoluchowski process
Авторы: Brenner,S.L., Nossal R.J., Weiss G.H.
We analyze a scheme, originally suggested by Smoluchowski, by which a diffusion coefficientD can be estimated by measuring the number of particles occupying a fixed region of a surface at various times. An expression is derived relating the variance of the estimated valueD to several experimental parameters. This expression is evaluated numerically to determine how statistical uncertainty depends on adjustable variables. Particular attention is given to experiments involving locomotion of migrating leukocytes.
