Rational screenning in combinatorial peptide libraries of protein functional loop

Redesigning the sequences of protein loops is a frequent practice in protein design. Based on the new results of protein loop database analysis, a rational computer simulation strategy is proposed to obtain functional proteins, which exploits a fast and accurate program to calculate the protein loop conformation, and at the same time, combines molecular docking method with combinatorial chemistry strategy to screen the combinatorial peptide library of protein loops. A characteristic of this method is that it separates the conformation computation of backbone from that of side chain and incorporates side chain growth into the docking procedure and therefore greatly reduces the computation by converting the huge computation on explosive conformations to relatively small computation on limited canonical backbone structures and side chain growth. This method can be practically used in screening combinatorial peptide libraries of protein loops.

Copula-based risk management models for multivariable RMB exchange rate in the process of RMB internationalization

This paper investigates the dependence of the exchange rate of onshore Renminbi (RMB) and offshore RMB against US dollar (i.e., CNY and CNH) based on copula models. Eleven different copulas were selected to construct multivariate distribution and estimate the value-at-risk for RMB exchange rate. Empirical results show that time-invariant Student-t copula is the best model to fit the sample data. The positive upper and lower dependence indicates that CNY and CNH series tend to move in the same direction. Moreover, the dependence between the two exchange rates is asymmetric, which means that traditional models, such as Pearson’s correlation, are inappropriate to measure the correlations between these markets. The best fitted model is chosen to estimate the financial risk, which can help business practitioners and policymakers track risk evolution and make good decisions.
