| Angiogenesis — the process of new blood-vessel growth — has an essential role in development, reproduction and repair. However, pathological angiogenesis occurs not only in tumour formation, but also in a range of nonneoplastic diseases that could be classed together as ‘angiogenesis-dependent diseases’. By viewing the process of angiogenesis as an ‘organizing principle’ in biology, intriguin...

Lifelong learning is often associated with the sociology and the economics of education. However, its broader and more holistic context, which includes learning through involvement in cultural activities, tourism, leisure, and recreation, is much less known. The relationship of this term to the rapidly changing world of Information and Communication Technologies and to various conceptions of in...

We consider a discrete model of euclidean quantum gravity in four dimensions based on a summation over random simplicial manifolds. The action used is the EinsteinHilbert action plus an R-term. The phase diagram as a function of the bare coupling constants is studied in the search for a sensible continuum limit. For small values of the coupling constant of the R term the model seems to belong t...

Starting from a field theoretical description of multicomponent anyons with mutual statistical interactions in the lowest Landau level, we construct a model of interacting chiral fields on the circle, with the energy spectrum characterized by a symmetric matrix gαβ with nonnegative entries. Being represented in a free form, the model provides a field theoretical realization of (ideal) fractiona...
