Controlling Chaos 12 MARCH 1990

It is shown that one can convert a chaotic attractor to any one of a large number of possible attracting time-periodic motions by making only small time-dependent perturbations of an available system parameter. The method utilizes delay coordinate embedding, and so is applicable to experimental situations in which a priori analytical knowledge of the system dynamics is not available. Important ...

NMFS 85 March 1990 Marine Farming and Enhancement

The recognition of an animal or a group of animals within a population is important for many reasons in fisheries research. Many types of tags and marks have been developed to aid biologists in recognizing animals (Rounsefell 1963, Farmer 1981). Unfortunately, no one technique has been totally satisfactory from a biological or technical standpoint. In 1983, the National Marine Fisheries Service...

The ribonuclease from an extinct bovid ruminant March 1990

The sequence of the ribonuclease from the ancestor of swamp buffalo, river buffalo, and ox, corresponding approximately to Pachyporrux lutidem, an extinct ruminant known from the fossil record, has been reconstructed using the rule of ‘maximum parsimony’. This protein and two sequences that may have been intermediates in the evolution of modern ribonuclease have been constructed in the laborato...
