Wilson disease (WD) (hepatolenticular degeneration) is an autosomal recessive disorder of copper metabolism due to absence or dysfunction of a Cu P-type ATPase which is essential for the transport of copper (Cu) into the bile. The discovery of the gene cation transporting P-type ATPase involved in the copper transport in many tissues was a breakthrough in the understanding of molecular basis of...

We study the online page replication problem. We present a new randomized algorithm for rings which is 2.37297-competitive, improving the best previous result of 3.16395. We also show that no randomized algorithm is better than 1.75037-competitive on the ring. This is the rst non-trivial lower bound for the problem. We initiate the study of replication in continuous metric spaces (the Nomads' P...

Submitted for the MAR07 Meeting of The American Physical Society Degenerate four-wave mixing with defocusing nonlinearity JASON FLEISCHER, WENJIE WAN, SHU JIA, Princeton University — We experimentally demonstrate four-wave mixing (FWM) effects in a defocusing nonlinear photorefractive medium, in both one and two dimensions. By using a rectangular crystal, we observe the nonlinear generation of ...
