A novel approach is proposed that quantifies the impact of parameter and control implementation inaccuracies on the performance of open loop control policies. Such information can be used to decide whether more laboratory experiments are needed to produce parameter estimates of higher accuracy, or to define performance objectives for lower level control loops which implement the optimal control trajectory...
We report the first poling fabrication of high quality LiNbO3 nonlinear photonic crystal with H-shaped fractal superlattice. Due to the self-similarity character of this structure, the collinear quasi-phase matched second-harmonics at 10 wavelengths, such as 674, 592, 577, 544, 517, and 499 nm, have been achieved in one crystal. Especially, for 499 nm second-harmonic laser spot, the normalized conversion...
The effects of process parameters-such as temperature evolution, cooling rate, and duration of overheating of Fe-Al-Cr melt-on the aluminothemic preparation of bulk nanocrystalline Fe-Al-Cr alloy were explored by using finite element analysis software ANSYS. The results show that the changes in temperature and cooling rate of the melt are evidently in the direction of height, while it remains nearly...
The programmed cell death 5 (PDCD5) protein plays an important apoptosis-accelerating role in cells undergoing apoptosis. Decreased expression of PDCD5 has been detected in various human carcinomas. Here we describe that one potent short interfering RNA (siRNA) against the PDCD5 (siPDCD5) specifically inhibits the expression of PDCD5 at both the mRNA and protein level. Cells with decreased PDCD5 expression...
Apoptosis is a genetically determined cell suicide program. Mitochondria play a central role in this process and various molecules have been shown to regulate apoptosis in this organelle. In the present study, we firstly identified that protein tyrosine phosphatase interacting protein 51 (PTPIP51) is a novel mitochondrial protein, which may induce apoptosis in HEK293T and HeLa cell lines. PTPIP51...
