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...

Falling sperm counts and global oestrogenic pollution: postscript.

T his Special Issue provides reflections after 20 years, summarized in 12 papers, on the controversial issue of alleged decline in human sperm output due to global oestrogen pollution by industrial chemicals. Virtanen et al. offer no specific critique of the original papers but focus on male reproductive function in their native country because Finnish men allegedly have better sperm production...

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...
