FDserver: A web service for protein folding research
*Summary:* To facilitate the study of protein folding, we have developed a web service for protein folding rate and folding type prediction as well as for the calculation of a variety of topological parameters of protein structure, which is freely available to the community.

Degeneracy of Landau Level and Quantum Group SL_q(2)
We show that there is a kind of quantum group symmetry in the
usual Landau problem and it is this quantum group symmetry that governs the
degeneracy of Landau levels. We find that under the periodic boundary
condition, the degree of degeneracy of Landau levels is finite, and it just
equals the dimension of the irreducible cyclic representation of the quantum
group .Comment: 10 pages, Preprint ( reprint ) of Nankai Institute of Mathematics.
