环境参数失配导致定位性能大幅度下降是匹配场定位所面临的难题之一.应用贝叶斯理论对环境聚焦,是当前解决该难题的研究热点.环境聚焦方法的实质是将未知环境参数和声源位置联合优化估计.然而,运动声源的位置时变性限制了观测时间长度和观测信息量,因此不得不利用很有限的观测信息来实现众多参数的估计.当航速较快或是环境信息的不确定性较大时,环境聚焦方法的效果迅速变差.借鉴卡尔曼滤波处理非平稳过程的参数估计思想,对航速较恒定的声源,本文将多个时刻的接收信号同时反演,引入能够描述声源位置随时间变化规律的时不变参数,以较少的时不变参数间接反演多个声源位置,从而有效降低待估参数维数.同时将当前估计结果作为下一次反演的先验信息,建立新的先验分布和代价函数,有效补偿个别异常数据,实现运动声源的连续定位.该方法在相同的环境不确定条件下,大幅度增加了观测时间和观测信息量,可以较好地改善环境聚焦方法的定位效果.

考虑到海洋石油平台之间和浮式生产储油装置(FPSO)与单点系泊系统之间的跨接软管成本昂贵,并且在安装过程中极易受损,为保证软管在安装过程中的完整性,提升安装作业效率,降低安装成本,采用悬链线理论对跨接软管安装过程进行分析,建立求解跨接软管长度、连接点角度、受力、高差以及弯曲半径、重心位置等关键控制参数的悬链线方程。在LF13-2油田开发项目跨接软管的安装过程中的应用表明,该方法快捷有效,可作为跨接软管安装控制的理论依据。

Visualization of the protective role of estrogen against female liver fibrosis via an ER viscosity NIR fluorescent probe

华东六省一市生物化学与分子生物学学会2006年学术交流会

作者： Zhi-Feng Yang, Zai-Long Cai, Sheng-Sheng Yang, Huan Chen, Ying Zong, zheng-Hua xiang, bing-Hua Jiao,Ji-fang Mao (Department of Biochemistry and Molecular Biology, Second Military Medical University, Shanghai, 200433, China)

The aberrant activation of NF-κB is associated with a virous tumors including breast cancer. Decrease of IKKα function can be attributed to defective activation of NF-κB. The aim of our study was to develop an efficient method for packaging and concentrating lentiviral stock that could produce high titer lentivirus to knockdown IKKa activity. The titer of the lentiviral stocks were more than 4×107TU/ml. To detect the effect of RNAi we examined the capability of lentiviral-mediated gene knockdown in MCF-7 cells. Results showed that the expression levels of IKKa were reduced dramatically compared to the control. Using this approach,we obtained the high titer lentiviral stock and detected the effect of RNAi capability of lentiviral-mediated gene knockdown in MCF-7 cells. Thus, IKKα-knockdown lentivirus might offer a selective therapy for breast cancer.

Endoplasmic reticulum(ER) viscosity has emerged as a new potential biomarker for hepatic fibrosis(HF). Herein, we report the first ER-targeting viscosity-responsive near-infrared(NIR) fluorescent probe HBT-PP for investigations of HF *** twisted intramolecular charge transfer(TICT) and the excited state intramolecular proton transfer(ESIPT) are combined to endow HBT-PP with the selective response towards viscosity(～62-fold) and a super large stokes shift(～320 nm). HBT-PP mainly targets organelle ER and is able to image the drug-or alcohol-induced viscosity elevation in living cells. Significantly,HBT-PP was successfully applied to visualize the gender difference in HF and the protective role of estrogen in restraining HF progression. Of note, after 10 min of stain with HBT-PP, HF lesions showed a stage-based response, indicating the potential of this probe in fast and early diagnosis of HF. These results clearly demonstrated the promising application of HBT-PP as a new tool for exploring ER viscosity-involved physiological and pathological processes.
