Universal quantum correlation close to quantum critical phenomena.

We study the ground state quantum correlation of Ising model in a transverse field (ITF) by implementing the quantum renormalization group (QRG) theory. It is shown that various quantum correlation measures and the Clauser-Horne-Shimony-Holt inequality will highlight the critical point related with quantum phase transitions, and demonstrate nonanalytic phenomena and scaling behavior when the size of the systems becomes large. Our results also indicate a universal behavior of the critical exponent of ITF under QRG theory that the critical exponent of different measures is identical, even when the quantities vary from entanglement measures to quantum correlation measures.

Structure Prediction and Analyzing of the Molecular Chaperone TCP1.

An improved Chou and Fasman method and the Robson method from Prosis software were applied to four TCP1s and five homologous proteins. The predictive results showed that there may exist two structural domains in TCPI with a "hinge region" between them, suggesting that the two structural domains may be alpha/beta barrels. The putative ATP-binding domain, whose motif centres around the absolute conserved GDGTT sequence at position 87-91 in TCP1Hu, was found to be a coil region in the predictive results.
