| 1 | Influence Analysis for Celebrities via Public Cloud and Social Platform显示文摘Recently, the online social networks have emerged as one of the important platforms for social users. Among millions of users, famous person from entertainment circle arouse our interest. They promote social relationship and establish their reputation via these platforms. To analyze the social influence of entertainment stars we propose and implement a public cloud based framework to crawl celebrities' social messages from Sina Weibo, store the gathered messages and conduct various analysis to assess the socia influence. It consist of three key components: task generation, resource management and task scheduling, and influence analysis. The task generation is responsible of acquiring celebrities' socia accounts and issue crawling tasks. We propose a cross-media method to extract social accounts from webpages. The resource management and task scheduling will dynamic adjust the rented resource to minimize the total computing cost while keeping Qo S. We propose a dynamic instance provisioning strategy based on the large deviation principle. The influence analysis will undertake various types of analysis, such as fan count, posting frequency, textual analysis, and so on. More than 10,000 celebrities' microblogs have been gathered so far, and some related gainers, such as celebrities and ad agencies can gain the illumination brought by our analysis. | Lu Liu Haoting Liang | 2016 | China Communications2016，13，8： | 3 |
| 2 | Application of Fe^Ⅲ-TAML/H2O_(2) system for treatment of fluoroquinolone antibiotics显示文摘Over the recent past,fluoroquinolone antibiotics(FQs)have raised extensive attention due to their potential to induce the formation of resistance genes and'superbugs',thus various advanced oxidation techniques have been developed to eliminate their release into the environment.In the present study,the prototype tetraamido macrocyclic ligand(Fe^Ⅲ-TAML)/hydrogen peroxide(H2O_(2))system is employed to degrade FQs(i.e.,norfloxacin and ciprofloxacin)over a wide p H range(i.e.,p H 6-10),and the reaction rate increases with the increase in p H level.The effect of dosage of Fe^Ⅲ-TAML and H2O_(2) on the degradation of FQs is evaluated,and the reaction rate is linearly correlated with the added amount of chemicals.Moreover,the impact of natural organic matters(NOM)on the removal of FQs is investigated,and the degradation kinetics show that both NOM type and experimental concentration exhibit negligible influence on the oxidative degradation of selected antibiotics.Based on the results of liquid chromatography-high resolution mass spectrometry and theoretical calculations,the reaction sites and pathways of FQs by Fe^Ⅲ-TAML/H2O_(2) system are further predicted and elucidated. | Zeyu Xian Sijia Liang Xin Jin Haoting Tian Jingyi Ling Chao Wang | 2021 | Journal of Environmental Sciences2021，33，1： | 1 |
| 3 | Osteopontin targeted theranostic nanoprobes for laser-induced synergistic regression of vulnerable atherosclerotic plaques显示文摘Vulnerable atherosclerotic plaque(VASPs)is the major pathological cause of acute cardiovascular event.Early detection and precise intervention of VASP hold great clinical significance,yet remain a major challenge.Photodynamic therapy(PDT)realizes potent ablation efficacy under precise manipulation of laser irradiation.In this study,we constructed theranostic nanoprobes(NPs),which could precisely regress VASPs through a cascade of synergistic events triggered by local irradiation of lasers under the guidance of fluorescence/MR imaging.The NPs were formulated from human serum albumin(HSA)conjugated with a high affinity-peptide targeting osteopontin(OPN)and encapsulated with photosensitizer IR780 and hypoxia-activatable tirapazamine(TPZ).After intravenous injection into atherosclerotic mice,the OPN-targeted NPs demonstrated high specific accumulation in VASPs due to the overexpression of OPN in activated foamy macrophages in the carotid artery.Under the visible guidance of fluorescence and MR dual-model imaging,the precise near-infrared(NIR)laser irradiation generated massive reactive oxygen species(ROS),which resulted in efficient plaque ablation and amplified hypoxia within VASPs.In response to the elevated hypoxia,the initially inactive TPZ was successively boosted to present potent biological suppression of foamy macrophages.After therapeutic administration of the NPs for 2 weeks,the plaque area and the degree of carotid artery stenosis were markedly reduced.Furthermore,the formulated NPs displayed excellent biocompatibility.In conclusion,the developed HSA-based NPs demonstrated appreciable specific identification ability of VASPs and realized precise synergistic regression of atherosclerosis. | Mengqi Xu Cong Mao Haoting Chen Lu Liu Yabin Wang Abid Hussain Sulei Li Xu Zhang Ruslan G.Tuguntaev Xing-Jie Liang Weisheng Guo Feng Cao | 2022 | Acta Pharmaceutica Sinica B2022，12，4： | 0 |
| 4 | Proximity Effect of Fe-Zn Bimetallic Catalysts on CO_(2) Hydrogenation Performance显示文摘The interaction between a promoter and an active metal crucially impacts catalytic performance.Nowadays,the influence of promoter contents and species has been intensively considered.In this study,we investigate the effect of the iron(Fe)-zinc(Zn)proximity of Fe-Zn bimetallic catalysts on CO_(2)hydrogenation performance.To eliminate the size effect,Fe_(2)O_(3)and ZnO nanoparticles with uniform size are first prepared by the thermal decomposition method.By changing the loading sequence or mixing method,a series of Fe-Zn bimetallic catalysts with different Fe-Zn distances are obtained.Combined with a series of characterization techniques and catalytic performances,Fe-Zn bimetallic proximity for compositions of Fe species is discussed.Furthermore,we observe that a smaller Fe-Zn distance inhibits the reduction and carburization of the Fe species and facilitates the oxidation of carbides.Appropriate proximity of Fe and Zn(i.e.,Fe_1Zn_(1)-imp and Fe_(1)Zn_(1)-mix samples)results in a suitable ratio of the Fe_5C_(2)and Fe_(3)O_(4)phases,simultaneously promoting the reverse water-gas shift and Fischer-Tropsch synthesis reactions.This study provides insight into the proximity effect of bimetallic catalysts on CO_(2)hydrogenation performance. | Shengkun Liu Qiao Zhao Xiaoxue Han Chongyang Wei Haoting Liang Yidan Wang Shouying Huang Xinbin Ma | 2023 | Transactions of Tianjin University2023，29，4： | 0 |
