In plants,the genome structure of hybrids changes compared with their parents,but the effects of these changes in hybrids remain *** reciprocal crosses between Col×C24 and C24×Col in Arabidopsis using high-throughput chromosome conformation capture assay(Hi-C)analysis,we found that hybrid three-dimensional(3D)chromatin organization had more long-distance interactions relative to parents,and this was mainly located in promoter regions and enriched in genes with heterosis-related *** interactions between euchromatin and heterochromatin were increased,and the compartment strength decreased in *** compartment domain(CD)boundaries,the distal interactions were more in hybrids than their *** the hybrids of CURLY LEAF(clf)mutants clfCol×clfC24and clfC24×clfCol,the heterosis phenotype was damaged,and the long-distance interactions in hybrids were fewer than in their parents with lower ***-seq data revealed higher levels of H3K27me3 in the region adjacent to the CD boundary and the same interactional homo-trans sites in the wild-type(WT)hybrids,which may have led to more long-distance *** addition,the differentially expressed genes(DEGs)located in the boundaries of CDs and loop regions changed obviously in WT,and the functional enrichment for DEGs was different between WT and clf in the longdistance interactions and loop *** findings may therefore propose a new epigenetic explanation of heterosis in the Arabidopsis hybrids and provide new insights into crop breeding and yield increase.

In Lagrangian formulation, it is extremely difficult to compute the excited spectrum and wavefunctions ora quantum theory via Monte Carlo methods. Recently, we developed a Monte Carlo Hamiltonian method for investigating this hard problem and tested the algorithm in quantum-mechanical systems in 1+1 and 2t1 dimensions. In this paper we apply it to the study of thelow-energy quantum physics of the (3+1)-dimensional harmonic oscillator.

0 INTRODUCTION Resonance frequency is an important indicator for structure health monitoring,which can be exacerbated by various natural forces,such as rainfall,earthquakes,and hurricanes(Wu et al.,2021;Shan et al.,2020;Gentile et al.,2016;Moser and Moaveni,2011).Clinton et al.(2006)found that changes in environmental factors could significantly affect the resonance frequency of the Millikan Library;and that compared with temperature,humidity and strong wind have greater impacts on resonance ***,some studies have confirmed the effects of environmental factors through mathematical statistical analyses,including Xia et al.(2006),Yuen and Kuok(2010),and Guéguen et al.(2017).Other studies(e.g.,Astorga et al.,2018)revealed a building’s self-healing ability,where the building’s resonance frequency drifts due to earthquake events,environmental factors,or random forced vibrations could gradually return to its original level,but the recovery time of frequency drift could be considerably different with respect to different environmental factors.

随着高速列车轻量化、高速化的趋势发展,风致安全及其控制问题愈发关键,基于线性轨道涡流制动器的横风安全主动控制方法可为风致安全控制提供新的思路。线性轨道涡流制动器常用于铁道车辆的非粘着制动,其在工作时会在转向架构架与钢轨之间产生垂向磁吸力,利用此特性将其作为主动控制作动器,并基于车辆-轨道耦合动力学理论,建立横风环境下高速列车主动安全控制动力学分析模型。结合高速列车的复杂非线性特点,采用模糊控制策略对线性轨道涡流制动器所产生的垂向磁吸力进行主动控制。研究结果表明,当强横风威胁到高速列车的安全行驶时,横风安全主动控制系统能够及时响应,降低列车迎风侧轮重减载率和转向架倾覆系数,从而提升列车的运行安全性。
