Characteristic Lie Algebra and Classification of Semi-Discrete Models
Characteristic Lie algebras of semi-discrete chains are studied. The attempt
to adopt this notion to the classification of Darboux integrable chains has
been undertaken.Comment: 33 pages, corrected typos, submitted to the Proceedings of the

An online Master's degree: Teaching and learning strategy vs. managerial constraints
This paper illustrates the work of a course team at Southampton Solent University to establish a delivery model for an online distance master’s degree. Working under the managerial constraint of ensuring that the course delivery is sustainably affordable, the focus was to develop a model that structures tutor to student engagement in such a way as to ensure the maintenance of a high standard of teaching and learning. This model is put forward as an approach that is applicable in a variety of contexts, and hence of value to course developers from other institutions investigating ways of effectively delivering online courses
On Some Algebraic Properties of Semi-Discrete Hyperbolic Type Equations
Nonlinear semi-discrete equations of the form t_x(n+1)=f(t(n), t(n+1),
t_x(n)) are studied. An adequate algebraic formulation of the Darboux
integrability is discussed and the attempt to adopt this notion to the
classification of Darboux integrable chains has been undertaken.Comment: 18 page
Slow regions percolate near glass transition
A nano-second scale in situ probe reveals that a bulk linear polymer
undergoes a sharp phase transition as a function of the degree of conversion,
as it nears the glass transition. The scaling behaviour is in the same
universality class as percolation. The exponents \gamma and \beta are found to
be 1.7 \pm .1 and 0.41\pm 0.01 in agreement with the best percolation results
in three dimensions.Comment: 7 pages, 3 figure
