| 3 | Optimal control strategies for stochastically excited quasi partially integrable Hamiltonian systems显示文摘在二不同控制策略设计了部分减轻伪的反应的这篇论文,受到随机的刺激的 integrable Hamiltonian 系统被建议。首先,由部分为伪使用随机的平均方法 integrable Hamiltonian 系统, n-DOF 部分控制了伪有随机的刺激的 integrable Hamiltonian 系统被变换成一套部分平均的 Itô 随机的微分方程。然后,与部分平均的 Itô 方程联系的动态编程方程被使用随机的动态编程原则提出。在第一控制策略,没有解决动态编程方程,最佳的控制法律从动态编程方程和控制限制被导出。在第二控制策略,最佳的控制法律被解决动态编程方程获得。最后,两回答控制,不受管束的系统通过解决与充分平均的 Itô 方程联系的 Fokker-Plank-Kolmogorov 方程被预言。一个例子被得出说明应用程序,二的有效性建议了控制策略。 | Ronghua Huan Maolin Deng Weiqiu Zhu | 2007 | Acta Mechanica Sinica2007，23，3： | 2 |
| 4 | Some applications of stochastic averaging method for quasi Hamiltonian systems in physics显示文摘Many physical systems can be modeled as quasi-Hamiltonian systems and the stochastic averaging method for quasi-Hamiltonian systems can be applied to yield reasonable approximate response sta-tistics.In the present paper,the basic idea and procedure of the stochastic averaging method for quasi Hamiltonian systems are briefly introduced.The applications of the stochastic averaging method in studying the dynamics of active Brownian particles,the reaction rate theory,the dynamics of breathing and denaturation of DNA,and the Fermi resonance and its effect on the mean transition time are reviewed. | DENG MaoLin ZHU WeiQiu | 2009 | Science China(Physics,Mechanics & Astronomy)2009，52，8： | 1 |

| 6 | Ancient DNA reveals the maternal genetic history of East Asian domestic pigs显示文摘Zoo-archaeological and genetic evidence suggest that pigs were domesticated independently in Central China and Eastern Anatolia along with the development of agricultural communities and civilizations.However,the genetic history of domestic pigs,especially in China,has not been fully explored.In this study,we generate 42 complete mitochondrial DNA sequences from~7500-to 2750-year-old individuals from the Yellow River basin.Our results show that the maternal genetic continuity of East Asian domestic pigs dates back to at least the Early to Middle Neolithic.In contrast,the Near Eastern ancestry in European domestic pigs saw a near-complete genomic replacement by the European wild boar.The majority of East Asian domestic pigs share close haplotypes,and the most recent common ancestor of most branches dates back to less than 20,000 years before present,inferred using new substitution rates of whole mitogenomes or combined protein-coding regions.Two major population expansion events of East Asian domestic pigs coincided with changes in climate,widespread adoption of introduced crops,and the development of agrarian societies.These findings add to our understanding of the maternal genetic composition and help to complete the picture of domestic pig evolutionary history in East Asia. | Ming Zhang Yichen Liu Zhipeng Li Peng Lü Jacob D.Gardner Maolin Ye Jihuai Wang Miaomiao Yang Jing Shao Weilin Wang Qingyan Dai Peng Cao Ruowei Yang Feng Liu Xiaotian Feng Lizhao Zhang Enwei Li Yunzheng Shi Zehui Chen Shilun Zhu Weiwei Zhai Tao Deng Ziyuan Duan E.Andrew Bennett Songmei Hu Qiaomei Fu | 2022 | Journal of Genetics and Genomics2022，49，6： | 0 |
| 7 | Random vortex induced vibration response of suspended flexible cable to fluctuating wind显示文摘A popular dynamical model for the vortex induced vibration(VIV)of a suspended flexible cable consists of two coupled equations.The first equation is a partial differential equation governing the cable vibration.The second equation is a wake oscillator that models the lift coefficient acting on the cable.The incoming wind acting on the cable is usually assumed as the uniform wind with a constant velocity,which makes the VIV model be a deterministic one.In the real world,however,the wind velocity is randomly fluctuant and makes the VIV of a suspended flexible cable be treated as a random vibration.In the present paper,the deterministic VIV model of a suspended flexible cable is modified to a random one by introducing the fluctuating wind.Using the normal mode approach,the random VIV system is transformed into an infinite-dimensional modal vibration system.Depending on whether a modal frequency is close to the aeolian frequency or not,the corresponding modal vibration is characterized as a resonant vibration or a non-resonant vibration.By applying the stochastic averaging method of quasi Hamiltonian systems,the response of modal vibrations in the case of resonance or non-resonance can be analytically predicted.Then,the random VIV response of the whole cable can be approximately calculated by superimposing the response of the most influential modal vibrations.Some numerical simulation results confirm the obtained analytical results.It is found that the intensity of the resonant modal vibration is much higher than that of the non-resonant modal vibration.Thus,the analytical results of the resonant modal vibration can be used as a rough estimation for the whole response of a cable. | Genjin MU Weiqiu ZHU Maolin DENG | 2023 | Applied Mathematics and Mechanics(English Edition)2023，44，12： | 0 |
| 8 | Thermally Induced Reversible Metal-to-Metal Charge Transfer in Mixed-Valence{Fe^(Ⅲ)_(4)Fe^(Ⅱ)_(4)}Cubes显示文摘The engineering of switchable moleculeswith dramatic magnetic change is currently among themost active areas in chemical research.Here,two cyanide-bridged mixed-valence{Fe^(Ⅲ)_(4)Fe^(Ⅱ)_(4)}cubes were prepared,both of which,interestingly,exhibited reversible thermally inducedmetal-to-metal charge transfer(MMCT)behavior between{Fe^(Ⅲ,LS)_(4)Fe^(Ⅱ,HS)_(4)}and{Fe^(Ⅱ,LS)_(4)Fe^(Ⅲ,HS)_(4)}configurations with the transition temperature(T_(1/2))of 274 and 230 K,respectively.These cubes provided a rare example of discrete homometallic complexes exhibiting the reversible MMCT rather than spin crossover behavior.In stark contrast to the heterometallic Fe/Co system,in which the charge transfer(CT)and spin transition(ST)processes occur simultaneously,the detailed structural and Mössbauer spectroscopy analyses confirmed the CT property without involving ST.In addition,both of these cubes showed excellent redox flexibility in solutionwith seven quasi accessible electronic states. | Maolin You De-Xuan Gan Yi-Fei Deng Dong Shao Yin-Shan Meng Xiao-Yong Chang Yuan-Zhu Zhang | 2022 | CCS Chemistry2022，4，7： | 0 |
