From a Zoo to a Zoology: Descriptive Complexity for Graph Polynomials

We outline a general theory of graph polynomials which covers all the examples we found in the vast literature, in particular, the chromatic polynomial, various generalizations of the Tutte polynomial, matching polynomials, interlace polynomials, and the cover polynomial of digraphs. We introduce the class of (hyper)graph polynomials definable in second order logic, and outline a research progr...

were sleeping; in these mosquitos were observed various stages of the development of the parasite. From such a study, considering the quantity of material used, we might expect, as indeed turned out to be the case, noteworthy results. Contemporaneously, mosquitos were studied, which were caught in stables and poultry yards, which, deriving their nourishment from the blood of birds and domestic ...

A Text-Book of Histology, Descriptive and Practical

methods of preparing the specimens, including the processes of hardening, staining, cutting and mounting, &c. It is illustrated by 174 beautifully drawn and lithographed coloured plates copied from typical sections, most of them remarkably accurate, others intentionally made diagrammatic. But when any departure from the actual specimen is made it is always plainly indicated ; and the student ca...

General Zoology

This little book contains a surprisingly large number of good descriptions of experimental techniques, presented with enough theory to make them intelligible. The chapters deal with blood, the circulation, respiration, muscle, peripheral nerve, the physical basis of body heat exchanges, and electronics in physiology. The methods are all physical rather than chemical, and such topics as electro-...
