There are some experiences that researcher come across quite number of time for very large networks in the initial samples such that they cannot finish the sampling procedure. Two solutions have been proposed and used by marine biologists which we discuss in this article: i) Adaptive cluster sampling based on order statistics with a stopping rule, ii) Restricted adaptive cluster sampling. Until...

Until quite recently it has been generally believed that the observed tertiary structure of a protein is controlled by thermodynamic and not kinetic processes. In this essay we review several recent results which call into question the universality of the thermodynamic hypothesis and discuss their implications for the understanding of protein folding.

Coffey (1911) and Stiles (1911) described somewhat similar techniques for the transplantation of ureters. Operations for transplantation previous to this date, suggested by various surgeons, were not satisfactory, and resulted in a high mortality rate. Coffey modified his first technique, designating it as Coffey II (1927), and Coffey III (1931). It is not until quite recently that more than a ...
