Mobile crowd sensing is an innovative paradigm which leverages the crowd, i.e., a large group of people with their mobile devices, to sense various information in the physical world. With the help of sensed information, many tasks can be fulfilled in an efficient manner, such as environment monitoring, traffic prediction, and indoor localization. Task and participant matching is an important issue in mobile crowd sensing, because it determines the quality and efficiency of a mobile crowd sensing task. Hence, numerous matching strategies have been proposed in recent research work. This survey aims to provide an up-to-date view on this topic. We propose a research framework for the matching problem in this paper, including participant model, task model, and solution design. The participant model is made up of three kinds of participant characters, i.e., attributes, requirements, and supplements. The task models are separated according to application backgrounds and objective functions. Offline and online solutions in recent literatures are both discussed. Some open issues are introduced, including matching strategy for heterogeneous tasks, context-aware matching, online strategy, and leveraging historical data to finish new tasks.

Unusual prostate carcinoma characterized by extensive metastasis, significantly increased serum level of prostatic-specific antigen, and neuroendocrine differentiation: a case report

引用

中华医学杂志(英文版) 2005年第3期 83-86页

作者： HU Yu-xin, YE Juan, JIANG Ying, ZHANG Qin-fang, WU yue-long and chen yue-yu Department of Medical Oncology , Department of Pathology , Department of General Surgery Jiading Central Hospital, Shanghai 201800, China

Some rare variants of prostate carcinoma have been described in recent years.1-3 In this article we report a man with uncommon prostate carcinoma with the following three pathological characteristics: （a） extensive metastasis to bone and lymph nodes of the abdomen, pelvis, and supraclavicular area; （b） significantly increased serum level of prostatic-specific antigen （PSA） as high as 1800 ng/ml; and （c） partial neuroendocrine differentiation in cancer tissue. The patient died 7 months after pathological diagnosis or 22 months after appearance of initial signs. This case has drawn our attention to the fact that pathological diversity of prostate neoplasm might easily lead to misdiagnosis or to delayed diagnosis, and moreover, reasonable therapy for such a case should be based on a thorough investigation. On the other hand, early initiation of appropriate treatment of advanced neuroendocrine carcinoma may improve the prognosis.

Unlocking the stable interface in aqueous zinc-ion battery with multifunctional xylose-based electrolyte additives

引用

Journal of Energy Chemistry 2025年第1期100卷 770-778页

作者： Xiaoqin Li Jian Xiang Lu Qiu Xiaohan chen Yinkun Zhao Yujue Wang Qu yue Taotao Gao Wenlong Liu Dan Xiao Zhaoyu Jin Panpan Li Institute for Advanced Study Chengdu University School of Mechanical Engineering Chengdu University College of Food and Biological Engineering Chengdu University Institute of Fundamental and Frontier Sciences University of Electronic Science and Technology of China College of Materials Science and Engineering Sichuan University

The growth of dendrites and the side reactions occurring at the Zn anode pose significant challenges to the commercialization of aqueous Zn-ion batteries（AZIBs）. These challenges arise from the inherent conflict between mass transfer and electrochemical kinetics. In this study, we propose the use of a multifunctional electrolyte additive based on the xylose（Xylo） molecule to address these issues by modulating the solvation structure and electrode/electrolyte interface, thereby stabilizing the Zn anode. The introduction of the additive alters the solvation structure, creating steric hindrance that impedes charge transfer and then reduces electrochemical kinetics. Furthermore, in-situ analyses demonstrate that the reconstructed electrode/electrolyte interface facilitates stable and rapid Zn2+ion migration and suppresses corrosion and hydrogen evolution reactions. As a result, symmetric cells incorporating the Xylo additive exhibit significantly enhanced reversibility during the Zn plating/stripping process, with an impressively long lifespan of up to 1986 h, compared to cells using pure ZnSO4electrolyte. When combined with a polyaniline cathode, the full cells demonstrate improved capacity and long-term cyclic stability. This work offers an effective direction for improving the stability of Zn anode via electrolyte design, as well as highperformance AZIBs.
