The mass ratio distribution of MBH binaries in the hierarchical model

引用

Research in Astronomy and Astrophysics 2015年第6期15卷 773-784页

作者： Sheng-nian xu Ye-Fei Yuan Jing-Meng Hao Ning-Yu Tang Key Laboratory for Research in Galaxies and Cosmology University of Science and Technology of China Chinese Academy of Sciences Academy of Mathematics and Systems Science Chinese Academy of Sciences

We present different mass ratio distributions of massive black hole （MBH） binaries due to different mechanisms involved in binary evolution. A binary system of MBHs forms after the merger of two galaxies, which has three stages： the dynamical friction stage, the stellar scattering or circumbinary disk stage, and the gravitational radiation stage. The second stage was once believed to be the ＂final parsec problem＂（FPP） as the binary stalled at this stage because of the depletion of stars. Now, the FPP has been shown to no longer be a problem. Here we get two different mass ratio distributions of MBH binaries under two mechanisms, stellar scattering and the cir- cumbinary disk interaction. For the circumbinary disk mechanism, we assume that the binary shrinks by interaction with a circumbinary disk and the two black holes （BHs） have different accretion rates in the simulation. We apply this simple assumption to the hierarchical coevolution model of MBHs and dark matter halos, and we find that there will be more equal-mass MBH binaries in the final coalescence for the case where the circumbinary mechanism operates. This is mainly because the secondary BH in the circumbinary disk system accretes at a higher rate than the primary one.

作者： nian Bao-yi xu Gang WU Jiang-ping YANG Li-rong Department of Chemistry and Biology Engineering Sanming University Sanming 365004 P. R. China College of Material Science and Chemical Engineering Zhejiang University Hangzhou 310027 P. R. China

Ionic liquids（ILs） are attracting much attention in various fields of chemical synthesis, electrochemical applications, liquid-liquid extractions, as well as biotransformations. Among those fields, the application of ILs as the potential green solvent for a wide variety of synthetic processes is an area of intense researches. High yield, high selectivity, and good catalytic charac-teristics have usually been achieved. After the isolation of products, ILs can usually be recovered and recycled many times by simple treating procedures, such as, filtration, extraction, and dryness.

了解云南省糖尿病视网膜病变(DR)的患病率和流行特征,探讨其相关危险因素,为云南省糖尿病慢性并发症的防治策略提供依据。横断面研究,2019年8至11月选取云南省16个社区和村庄登记的1524例糖尿病患者作为研究对象。通过问卷完成信息采集,测量人体形态学指标及相关生化指标,计算DR的患病率,采用logistic回归分析法筛选DR的危险因素。云南省糖尿病患者DR患病率为16.0%(244/1524),其中轻度非增殖性DR(mild-NPDR)的患病率为4.5%(69/1524),需要转诊的DR(RDR)的患病率为11.5%(175/1524)。糖化血红蛋白(HbA_(1c))≥7.0%是mild-NPDR(OR=1.872,95%CI 1.055~3.323)和RDR(OR=4.821,95%CI 2.917~7.969)的危险因素;血压≥130/80 mmHg(1 mmHg=0.133 kPa)是mild-NPDR(OR=1.933,95%CI 1.112~3.358)和RDR(OR=1.505,95%CI 1.063~2.130)的危险因素。云南省糖尿病患者中有16.0%合并DR;其中约71.7%需要转诊眼科,糖尿病患者RDR高发与血糖、血压控制较差有关。

This paper presents an Enhanced Moth-Flame Optimization （EMFO） technique based on Cultural Learning （CL） and Gaussian Mutation （GM）. The mechanism of CL and the operator of GM are incorporated to the original algorithm of Moth-Flame Optimization （MFO）. CL plays an important role in the inheritance of historical experiences and stimulates moths to obtain information from flames more effectively, which helps MFO enhance its searching ability. Furthermore, in order to overcome the disadvantage of trapping into local optima, the operator of GM is introduced to MFO. This operator acts on the best flame in order to generate several variant ones, which can increase the diversity. The proposed algorithm of EMFO has been comprehensively evaluated on 13 benchmark functions, in comparison with MFO. Simulation results verify that EMFO shows a significant improvement on MFO, in terms of solution quality and algorithmic reliability.
