New syndiotactic cyclic octapeptides, namely cyclo(–D-Phe-L-Asp–D-Phe–L-Asn–D-Phe–L-Asp–D-Phe–L-Asn–) (1) and cyclo(–D-N-MeAla–L-Asp–D-N-MeAla–L-Asn–D-N-MeAla–L-Asp–D-N-MeAla–L-Asn–) (2), have been prepared, and preliminary structural studies have been conducted. The synthesis of the linear peptides was performed by using Fmoc chemistry, and head-to-tail cyclization was accomplished by using an orthogonal protection strategy and a support-bound cyclization step. Acidification of aqueous solutions of cyclic octapeptide (1) initiated formation of needlelike crystals whose morphology and infrared absorption behaviour suggested that they were hydrogen-bonded nanotubular aggregates of (1).

Optimal Protection

Background: User behavior models have been widely used to simulate attack behaviors in the security domain. We revised all patents related to response to attack behavior models. How to decide the protected target against multiple models of attack behaviors is studied. Methods: We utilize one perfect rational and three bounded rational behavior models to simulate attack behaviors in cloud computing, and then investigate cloud provider’s response based on Stackelberg game. The cloud provider plays the role of defender and it is assumed to be intelligent enough to predict the attack behavior model. Based on the prediction accuracy, two schemes are built in two situations. Results: If the defender can predict the attack behavior model accurately, a single-objective game model is built to find the optimal protection strategy; otherwise, a multi-objective game model is built to find the optimal protection strategy. Conclusion: The numerical results prove that the game theoretic model performs better in the corresponding situation.
