This, the 22nd issue of the Transactions on Computational Science
journal, consists of two parts. The first part is devoted to neural and
social networks and the second to geometric modeling and simulation. The
four papers in Part I span the areas of information-driven online social
networks, neural networks, collaborative memories, and stability
controls in multi-agent networked environments. The four papers in Part
II cover the topics of shape reconstruction from planar contours, sharp
feature preservation through wavelets, protein structure determination
based on the beta-complex, and fast empty volume computation in
molecular systems.
