This advanced text explores the relationship between Markov processes and potential theory, in addition to aspects of the theory of additive functionals. Geared toward graduate students, "Markov Processes and Potential Theory" assumes a familiarity with general measure theory, while offering a nearly self-contained treatment.
Topics include Markov processes, excessive functions, multiplicative functionals and subprocesses, and additive functionals and their potentials. A concluding chapter examines dual processes and potential theory. Exercises appear throughout the text, and a selection...

This invaluable volume, written by an international group of scientists, presents an overview of the AdoMet-dependent methyltransferases, with special emphasis on structure-function relationships.

S-adenosyl-L-methionine (AdoMet) is the second most commonly used enzyme cofactor after ATP. The AdoMet-dependent methyltransferases act on a wide variety of target molecules, including DNA, RNA, protein, polysaccharides, lipids and a range of small molecules.

The well-conserved architecture of these enzymes, and the implications of this conservation for their evolutionary history, are major...

DNA methylation is essential for the normal development and functioning of organisms. This volume discusses the latest developments in this very active field of research. It presents the evolution of DNA methylation, mammalian DNA methyltransferases, DNA methylation and demethlyation, DNA methylation and silencing and the role it plays in medicine including cancer.

* Discusses new discoveries, approaches, and ideas * Contributions from leading scholars and industry experts * Reference guide for researchers involved in molecular biology and related fields

Let {Xti t O} be a Markov process in Rl, and break up the path X t into (random) component pieces consisting of the zero set ({ tlX = O}) and t the "excursions away from 0," that is pieces of path X.: T::5 s::5 t, with Xr- = X = 0, but X. 1= 0 for T
