The ＇lithium problem, in Big Bang nucleosynthesis（BBN） has recently focused on reactions involving ^7 *** ^6 Li（p,γ）^7 Be reaction can provide us not only with information about ^6 Li destruction but also with information about ^7 Be production. In the present work, the proton spectroscopic factor in ^7 Be is extracted to be 0.70 ± 0.17 from the angular distribution of ^7 Be（d, ^3 He）^6 Li at Ec.m. = 6.7 MeV. This value is then used to compute the direct component of the astrophysical ^6 Li（p,γ）^7 Beg.s. S（E） factors and determine the resonance parameters from the total S（E） factors.

Einstein-Podolsky-Rosen(EPR) entanglement involving a pair of particles entangled in their positions and momenta is of special interest in the field of quantum information. Previously, EPR entanglement has been studied in different physical systems but in fixed coordinate spaces. Here, we demonstrate an experiment of ghost imaging and ghost interference in rotated position-momentum spaces by using positionmomentum entangled photons generated from a hot atomic ensemble. By using different image objects,the measured position-momentum correlations exhibit intriguing dynamics, including gradual decrease and axis-independent EPR entanglement. The reported results on manipulating the EPR entanglement in rotating coordinate spaces hold promise in quantum communication and distant quantum image processing.

A flexible and adaptable design method for the tooth crown is presented based on the direct manipulation of free-form deformation （FFD）. The correct shape of the tooth crown can be obtained by adding, modifying, and deleting constraint points or load points based on stretching and compressing operation. Finally, an example is given to illustrate the method to be efficient.

Gene-Gene Interaction between PPARd and PPARy Is Associated with Abdominal Obesity in a Chinese Population

引用

Journal of Genetics and Genomics 2012年第12期39卷 625-631页

作者： Yi ding Zhi-Rong Guo Ming Wu Qiu Chen Hao yu Wen-Shu Luo Department of Epidemiology School of Public HealthSoochow University Center for Diseases Control of Jiangsu Province Center for Disease Control of Changzhou

The peroxisome proliferator-activated receptors （PPARs） -α, -δ/β and -γ are the ligand-activated transcription factors that function as the master regulators of glucose, fatty acid and lipoprotein metabolism, energy balance, cell proliferation and differentiation, inflarn- marion, and atherosclerosis. The objective of the current study was to examine the main and interactive effect of seven single nucleotide polymorphisms （SNPs） of PPARδ/γ, in contribution to abdominal obesity. A total of 820 subjects were randomly selected and no indi- viduals were related. The selected S NPs in PPARδ （rs2016520 and rs9794） and PPARγ （rs10865710, rs 1805192, rs709158, rs3856806, and rs4684847） were genotyped. Mean difference and 95% confident interval were calculated. Interactions were explored by the method of generalized multifactor dimensionality reduction. After adjustment for gender, age, and smoking status, it was found that the carriers of the C allele （TC ＋ CC） of rs2016520 were associated with a decreased risk of abdominal obesity compared to the carriers of the TT genotype （mean difference = -2.63, 95% CI = -3.61-1.64, P 〈 0.000t）. A significant two-locus model （P = 0.0107） involving rs2016520 and rs 10865710 and a significant three-locus model （P = 0.0107） involving rs2016520, rs9794, and rs 1805192 were observed. Overall, the three-locus model had the highest level of testing accuracy （59.85%） and showed a better cross-validation consistency （9/10） than two-locus model. Therefore, for abdominal obesity defined by waist circumference, we chose the three-locus model as the best interaction model. In conclusion, the C allele in rs2016520 was significantly associated with a lower abdominal obesity. Moreover, an interaction among rs2016520, rs1805192, and rs9794 on incident abdominal obesity could be demonstrated.

针对集总干扰下四旋翼飞行器的姿态控制问题,提出了一种基于线性扩张状态观测器的快速连续非奇异终端滑模控制策略。该方法通过线性扩张状态观测器来估计和补偿集总干扰的影响,提高控制器的稳定性;借助非奇异终端滑模面有限时间收敛的特性设计控制律,加快控制器的收敛速度;控制器的稳定性分析由Lyapunov函数得以证明。引入樽海鞘群算法来优化控制器中的参数,提升控制性能。进一步地,引入一维正态云模型与自适应算子来克服参数整定算法的固有缺陷,增强其优化能力。通过仿真与试验验证了本文方法的有效性与实用性,结果表明:在阵风干扰下,本文方法比线性自抗扰控制策略具有更高的跟踪精度、更强的抗干扰能力与更快的响应速度。
