I gave up with Wordpress as, although pretty, it is neither reliable nor secure.
I went back to this old system I wrote years ago which has no hackable database behind it.
The equations I produced using CodeCogs with grateful thanks.

Strong evidence of an information-theoretical conservation principle linking all discrete systems
|
A complete general theory of why disparate discrete systems such as the proteome
and collections of computer software share identical properties such as their
length distributions. There's a lot more to come.

CoHSI IV; Unifying Horizontal and Vertical Gene Transfer - is Mechanism Irrelevant ?
|
Shows that CoHSI correctly predicts the rate at which proteins are copied across all domains of life, demonstrating that viruses are fundamental to this process.

CoHSI III: Long proteins and implications for protein evolution
|
Shows that the longest protein depends only on the size of the protein aggregation and demonstrates that this leaves a recognisable footprint in the phylogenetic tree including evidence of a previously undocumented mass extinction.

Conservation of Hartley-Shannon Information (CoHSI) in discrete systems
|
The length distribution of discrete systems such as the complete Proteome,
collections of Software in any language and digital Music all obey
the following equation
which for components large compared with their alphabet asymptotes to
a power-law
It has nothing to do with natural selection, human volition or any other action
other than the natural behaviour of large random systems. It is an
emergent property and in important ways,
software and protein structural properties are therefore identical.

Conservation of Information in Proteins
|
In proteins, CoHSI predicts the remarkable constancy of average
protein length and also why very long proteins exist.

Like all my recent work, complete computational reproducibility packages
are provided which are capable of reproducing each diagram, table and statistical
result using entirely open source. As an example, for this paper it can
be found at
Reproducibility package
and a tutorial in how to build reproductibility packages is given here.

Software's Hidden Clockwork
|
Just like proteins, all software systems have
a hidden clockwork which forces them into the same component size distribution
whatever they do, whoever wrote them and whatever technology or
language was used. Just watch as 100 million lines of C, C++, Java, Fortran,
Ada and Tcl-Tk asymptote to the CoHSI distribution in 1/2 million line chunks.
