 <content>\subsection{Applications in Physics} 

 A `categorification' of theoretical physics (including quantum field theories) 
began as early as 1968 \cite{Baianu-Marinescu68,Baianu71a,Baianu71b}; this `categorification' process in physics continues today, especially after 1985 (\cite{Baianu87} and references cited therein). Other recent applications are in
computer programming theory, automata theory, ontology/categorical ontology \cite{Bggb4} and linguistics.


\subsection{Applications in Mathematical Biophysics}
Categories of sets were first introduced in mathematical biophysics in 1958 
\cite{Rosen58a,Rosen58b}, followed by the introduction of biotheoretical models in categories with structure in 1968-1971 \cite{Baianu-Marinescu68,Baianu70, Baianu71a, Baianu71b}. For a review of the earlier work see ref. \cite{Baianu87}.
