In order to improve the accuracy of the data fusion filter, a tightly-coupled ultra wide band(UWB)/inertial navigation system(INS)-integrated scheme for indoor human navigation will be investigated in this paper. In this scheme, the data fusion filter employs the difference between the INS-measured and UWB-measured distances as the observation. Moreover, the predictive adaptive Kalman filter(PAKF) for the tightly-coupled INS/UWB-integrated human tracking model with missing data of the UWB-measured distance will be designed, which considers the missing data of the UWB-based distance and employs the predictive UWB-measured distance. Real test results will be done to compare the performance of the Kalman filter(KF), adaptive Kalman filter(AKF), and the PAKF. The test results show that the performance of the AKF is better than the KF. Moreover, the proposed PAKF is able to maintain the performance of the filter when the UWB-based measurement is unavailable.

Background Mediastinal lesions are often difficult to diagnose in clinical practice because of the unique anatomical position of the mediastinum, which makes performance of biopsy difficult. The value of endobronchial ultrasound-guided transbronchial needle aspiration in the diagnosis of lung cancer and mediastinal lymph node staging has been widely accepted. However, few studies have been conducted on the value of endobronchial ultrasound-guided transbronchial needle aspiration in the diagnosis and differential diagnosis of mediastinal lesions. The current study was conducted to investigate the value of endobronchial ultrasound-guided transbronchial needle aspiration in the diagnosis and differential diagnosis of isolated mediastinal lesions without lung abnormalities. Methods We retrospectively analyzed the data of patients with isolated mediastinal lesions without lung abnormalities for whom endobronchial ultrasound-guided transbronchial needle aspiration examination was performed at the Department of Thoracic Surgery of Peking University People＇s Hospital, between September 2009 and December 2010. For patients who could not be diagnosed with endobronchial ultrasound-guided transbronchial needle aspiration, surgical biopsy or more than 6 months of clinical and imaging follow-up was carried out. Results Endobronchial ultrasound-guided transbronchial needle aspiration was performed for 60 patients with isolated mediastinal lesions. Correct diagnosis was made in 48 cases. Nineteen cases were malignant, and 29 were benign. The rate of correct diagnosis was 80%. The sensitivity, specificity, and accuracy of endobronchial ultrasound-guided transbronchial needle aspiration in distinguishing benign from malignant mediastinal lesions were 95%, 100%, and 98%, respectively. The examination was tolerable for all patients. No associated complications were observed. Conclusion Endobronchial ultrasound-guided transbronchial needle aspiration is a safe and effective method of di

Dinuclear metal synergistic catalysis （DMSC） has been proved powerful in boosting CO2reduction,while this has not been achieved in heterogeneous catalysts with long-range order *** this study,we,by introduction of metal catalytic centers into an indium-based metal-organic framework （MOF）,obtained a series of isostructural In-MOFs,including three MOFs with mononuclear metal catalytic center （M-In）,three MOFs with dinuclear homometallic catalytic centers （MM-In）,and three MOFs with dinuclear heterometallic catalytic centers (MM’-In,M/M’=Co（II）,Ni（II）,Zn（II）).It was found that all these MOFs can serve as catalysts for photochemical CO2reduction to *** with M-In,the catalytic activities of MM-In were obviously enhanced,and that of MM’-In was further significantly *** example,the CO yield of Co Zn-In reaches a record value of 12,700μmol g-1h-1,which is 4.0,8.1,9.4,and 18.6-fold higher than that of Co Co-In,Zn Zn-In,Co-In,and Zn-In,***,the catalytic activities of Co Ni-In and Ni Zn-In also show different fold increase than those of corresponding dinuclear homometallic and mononuclear metallic *** results of control experiments and theoretical calculation reveal that the higher catalytic activities of MM-In over M-In can be ascribed to the DMSC effect,and the higher catalytic activity of MM’-In over MM-In can be ascribed to the strengthened DMSC *** work reveals the relationship between DMSC effect and bimetal centers in CO2reduction,which provides new insights into the DMSC and paves a new way to design highly active catalysts for photochemical CO2reduction.

针对目前在多孔河岸式溢洪道上采用窄缝挑坎消能工,都是沿闸墩用长墩隔开,至出口段将墩体升高加厚、急剧收缩成窄缝的结构形式。全程隔墩混凝土用量大,加上强大侧向水压力荷载等影响到工程投资、结构安全与泄洪运行管理问题。该设计提出省去泄槽中部的长隔墩,只在溢洪道出口连续挑坎下部加入"卧底式窄缝",借以实现继续应用收缩式消能工。经模型试验表明:通过"分段连续坎"与"窄缝"的差动作用,出射水舌抛射呈十、廿、卅字形,加大入水面积和碰撞机率,消能效果良好,并方便人为控制水舌落点。在水电工程中有扩大应用潜力。

As a class of functional crystalline porous materials, metal-organic frameworks(MOFs) gained rapid development in the past three decades and a large number of MOFs with ordered structures, high surface areas, and functionalized channels have been investigated. MOFs and MOF-derived/composite materials show great potential in many application fields. In this review, we discussed the main applications of MOFs and MOF-derived/composite materials in small molecule storage, separation, luminescence, sensing, multitype catalysis, and energy storage. In addition, challenges and problems in the future research of MOFsrelated fields are also discussed.
