Landmarks in Hepatology: A postscript

A postscript

numerous contributions to the discussion of general questions in evolutionary biology, and for providing an evolutionary perspective on other areas of biology, such as ecology and development. He was a persistent critic of group-selectionist thinking and of the theory of punctuated equilibrium. He published fourteen books and collections of papers on an astonishing diversity of subjects, as wel...

Postscript

A postscript on cryotypes.

Phylogenetic analysis is a theoretical construct that employs a nested hierarchy of 'subroutines' to relate discrete elements ('phyle' from the Greek for 'tribes') to their wider origins ('genesis' from the Greek for 'birth' or 'origins'). Its modern usage ranges from molecular biology to ecology, where it may be used to relate elements not connected by DNA (Wanntorp et al., 1990). Cryotypes ma...

Better PostScript than PostScript: portable self-extracting PostScript representation of scanned document images

We present a Pattern Matching Based Compression (PMBC) system which compresses scanned documents into PostScript format. The output of a PMBC system is a pattern library, or font, and a series of pattern indices and positions. PMBC represents scanned documents in the same way that word processing programs represent their output pages. We explore various PostScript representations of this output...

It was not until the discovery of hepatitis B virus in 1967 and hepatitis C virus in 1989 that the specialty began to expand, particularly with the development of effective antiviral therapy. Phenomenal advances in the knowledge of immune reactions also ...
