THE IMPLEMENTATION OF CANONICAL SIMPLIFICATION ALGORITHM FOR FEP EXPRESSIONS
Shun, Guo Fu,Cheng, Li Sheng,Xin, Luo,Ping, Zou 대한전자공학회 1992 HICEC:Harbin International Conference on Electroni Vol.1 No.1
Fractional Exponential Polynomials (FEP) are the extension of REP expressions [1]. This paper deals FEP with canonical forms of FEP expressions and the algorithm simplifying FEP expressions, especially emphasizing the problems relevant to the algorithm realization.

Complexes M($C_7H_2NO_5)3H_2O{\cdot}H_2O{\cdot}0.25MeCN$ (M=Ni, Co) were crystallized from the reactions of $Ni(CH_3COO)_2{\cdot}4H_2O\;or\;Co(CH_3COO)_2{\cdot}2H_2O$ with KSCN and 2,6-dicarboxy-4-hydroxypyridine (chelidamic acid). The structures were characterized by X-ray crystallography. The crystal structures of 1 and 2 show a distorted octahedral coordination geometry around the M(II) ions, which are chelated by one nitrogen atom and two oxygen atoms of the chelidamic acid and three water molecules. Complexes 1 and 2 display the hydrogen-bonded 3D framework. The magnetic behavior of 2 exhibits antiferromagnetic interaction.

<P><B>Abstract</B></P> <P>The acetyltransferase TIP60 (also known as Kat5) is a member of the MYST family of histone acetyltransferases and was initially identified as a cellular protein. TIP60 acetylates histone and non-histone proteins and is involved in diverse biological processes, including apoptosis, cell cycle, and DNA damage responses. In this study, a specific inhibitor of TIP60 was used to detect the function of TIP60 in porcine parthenogenetic embryos. The results showed that TIP60 inhibition impaired porcine parthenogenetic embryonic development. The mechanism of TIP60 was also determined. We found that the TIP60 inhibition impaired embryonic development by ROS induced DNA damage, as demonstrated by the number of γH2A in the nuclei. TIP60 inhibition triggered DNA damage through the regulation of p53-p21 pathway and TIP60 played a role in DNA repair. TIP60 inhibition decreased the efficiency of DNA repair by regulating 53BP1-dependent repair after DNA damage. Inhibition of TIP60 also increased the adaptive response, autophagy, by modulating LC3. Therefore, TIP60 plays a role in early porcine parthenogenetic embryonic development by regulating DNA damage and repair.</P> <P><B>Highlights</B></P> <P> <UL> <LI> TIP60 inhibition disrupted the embryonic development. </LI> <LI> TIP60 inhibition triggered the DNA damage and incomplete DNA repair due to the excessive generation of ROS. </LI> <LI> TIP60 inhibition induced the apoptosis and autophagy. </LI> </UL> </P>

The complexity of macro-fiber composite (MFC) materials increasing the difficulty in simulation and analysis of MFC integrated structures. To give an accurate prediction of MFC bonded smart structures for the simulation of shape and vibration control, the paper develops a linear electro-mechanically coupled static and dynamic finite element (FE) models based on the first-order shear deformation (FOSD) hypothesis. Two different types of MFCs are modeled and analyzed, namely MFC-d31 and MFC-d33, in which the former one is dominated by the d31 effect, while the latter one by the d33 effect. The present model is first applied to an MFC-d33 bonded composite plate, and then is used to analyze both active shape and vibration control for MFC-d31/-d33 bonded plate with various piezoelectric fiber orientations.
