A high sensitivity fiber optic temperature sensor based on Vernier effect in microwave photonic filter based on two paralleled F-P (Fabry-Perot) fiber ring is proposed and experimentally verified. Sensitivity is improved through the Vernier effect， which is caused by two parallel F-P fiber rings with approximate lengths. Temperature interrogation is achieved by monitoring the notch frequency of the superimposed frequency response curve. The temperature sensitivity of -484.514kHz/℃ is achieved in experiment， which is 57 times of the sensor without Vernier effect. The improved sensitivity and simple structure make it have wide potential applications in temperature monitoring of power systems.

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.

随着胆道外科现代诊疗体系的建立与科学研究范式的转变, 无论是良性还是恶性胆道疾病, 均已进入精准化、个体化、全程化及多学科协作的诊疗和研究阶段。然而胆道外科医师仍面临着两大困境:(1)外科技术在降低良性胆道疾病致残率、提高胆道肿瘤患者生存率方面进入了瓶颈期;(2)对于"切胆保胆""如何减黄"等临床争议, 传统的临床研究似乎难以给出确切答案。借鉴系统生物学的理念, 作者提出了"胆道生态系统"的概念框架:胆管是丛林, 血管、淋巴管、神经和免疫系统是土壤, 干细胞是种子, 胆汁是河流, 肝细胞是河流的发源地。良恶性疾病具有动态转化的特征;不同部位的胆管构成"大"环境, 胆汁形成"小"环境, 不同细胞组成"微"环境;细胞亚群具有不同状态及多样性, 并受复杂分子信号网络的调控。作者据此进一步凝练了胆道外科的若干关键科学问题, 提出了优化研究范式的建议, 旨在从全局视角推动学科交叉融合, 推动胆道外科临床及转化研究。
