In the education sector,blockchain is currently at the end of the peak of inflated expectations in Gartner’s Hype ***,it is crucial to understand whether this technology meets the expectations of Higher Education Institutions(HEIs).We go on an expedition to identify blockchain application scenarios and its potential for HEI administration-the universities are digitalized to just 23.3%.Current information systems research addresses classifications of blockchain-based projects(application level)rather than their technical realization(protocol level).Thus,when evaluating blockchain application scenarios in HEI administration,we intensively consider the technical side of blockchain-based *** perform a threestep approach:(1)systematic literature review,(2)qualitative exploratory semi-structured interviews to sup-plement information on market-ready solutions,and(3)an evaluation of the potential of the blockchain-based projects identified,based on HEI administration *** find that the leading blockchain application scenarios are credential verification and *** the protocol level,we obtain equivocal results regarding the technical realization of projects,e.g.,their underlying blockchain types and storage *** the application level,when discussing the potential of different projects,we find that most of them address adaptability,complexity decomposition,and cost reduction requirements between HEIs;interest diversity and stakeholder collaboration between HEIs and business actors;privacy and trust between HEIs and students.

cerebrovascular disease of genetic origin characterized by abnormally dilated capillaries and a wide spectrum of symptoms,including headaches,seizures,neurological deficits,and intracerebral *** unpredictable clinical course and the current lack of therapies make the identification of prognostic and predictive biomarkers an imperative research challenge.1 Herein,we provide evidence that galectin-3(Gal-3),a major tissue and circulating biomarker of oxidative stress and inflammation,is significantly up-regulated both in CCM patients and ***,wholetranscriptome sequencing,qRT-PCR,and Western blotting studies demonstrated a significant up-regulation of Gal-3 expression levels both in surgical CCM specimens and in blood samples of CCM patients.

自2019年住建部等部委发布“城镇污水处理提质增效三年行动方案”以来，城市污水管网和污水处理厂在质量和运行效率方面都取得了显著的改善。去年住建部等部委进一步提出“深入打好城市黑臭水体治理攻坚战实施方案”，要求在以前工作的基础上，努力解决河流“雨后黑臭”和雨季河流断面水质下降问题，力争到2025年，进水BOD 浓度高于100毫克/升的城市生活污水处理厂规模占比达90%以上，城市生活污水集中收集率达到70%以上。水业界面临着防止雨后河流返黑和改善雨季河流水质等新任务。因此，结合近年来成绩?实践和欧美的经验教训，提出和讨论了与进一步改善网-厂-水体城市污水系统升级改造及运行效率相关的四个问题: 分流制管网有没有外(雨)水入侵和溢流? 污水厂的进水浓度应多高? 为什么部分污水厂需局部扩容?为什么污水管道中流速低于“自净流速”? 并在此基础上，对相关工作提出了建议。

Sophisticated principles of design and material integration of biomaterials have long been a major source of inspiration for the development of artificial materials[1,2].In recent years,inspired by the multi-level architecture of biomineral materials such as shell nacre[3,4],tooth enamel[5],and bone[6],several strong and tough bioinspired structural materials like advanced ceramic composites and metallic alloys have been reported.

Charmonium spectroscopy and decay at CLEO-c

引用

Chinese Physics C 2010年第6期34卷 621-625页

作者： helmut Vogel Department of Physics Carnegie Mellon University

We report recent results on charmonium spectroscopy and decay from the CLEO-c experiment at the Cornell electrompositron storage ring accelerator, CESR. Most of the results are based on the analysis of 54 pb-1 of luminosity collected at the ψ（2S） resonance, corresponding to 27 M ψ（2S） decays. We concentrate on radiative decays of ψ（2S） and J/ψ, on two-body mesonic decay of XcJ, on hadronic decay of the he, and on higher multipoles in the two-photon cascade ψ（2S）→γχcJ, XcJ→γJ/ψ.
