Preparations of intact flagella isolated from Caulobacter crescentus CB13B1a were found to contain two protein species of apparent molecular weights 28,000 and 25,000. Both proteins cross-reacted completely with each other and with purified flagella in Ouchterlony double-immunodiffusion assays. The amino acid compositions of the isolated proteins were similar to one another but precluded any pr...

We present a method for estimating the complexity of an image based on Bennett’s concept of logical depth. Bennett identified logical depth as the appropriate measure of organized complexity, and hence as being better suited to the evaluation of the complexity of objects in the physical world. Its use results in a different, and in some sense a finer characterization than is obtained through th...

Working within the framework of the propositional system formalism, we use a previous study [1 ] of the description of two independent physical systems as one big physical system to derive a characterization of a (non-interacting) physical subsystem. We discuss the classical case and the quantum case.

OBJECTIVE To examine analytically the question of whether the characterization of somatoform disorders (SFDs) in Diagnostic and Statistical Manual, Fourth Edition (DSM-IV) provides adequate grounds for classifying them as mental disorders rather than as physical disorders. METHODS Analytical examination. RESULTS There are prima facie grounds for classifying SFDs as physical disorders since ...
