| 1 | Harnessing Internet finance with innovative cyber credit management显示文摘In the last two decades,Internet technologies,such as cloud computing,mobile communications,social media,and big data analytics,have brought tremendous changes to our society and reshaped the business in various industries.Specifically,the mushrooming innovations in the financial area fertilized by information and communication technologies indicates the advent of the Internet finance era.Applying the exploratory research approach,we investigate major innovative Internet-based financial services and classify them into five categories,as of e-commerce,e-payment,e-money market,online loan services,and digital currencies.Then we propose a market structure of Internet finance extended from the traditional financial market.We claim that credit management is the key issue in the marketplace of Internet finance,characterized by big data analytics,in which cyber credit appears as whole-process,multi-dimensional,and holographic.We further suggest that cyber credit be represented in the form of vector to overcome the limits of traditional single-value measure in cyber credit management.Based on this framework,we raise main research issues in Internet finance from the perspectives of theory,technology,and governance. | Zhangxi Lin Andrew B.Whinston Shaokun Fan | 2015 | Financial Innovation2015，1，1： | 7 |
| 2 | Gravitational wave astrophysics, data analysis and multimessenger astronomy显示文摘This paper reviews gravitational wave sources and their detection. One of the most exciting potential sources of gravitational waves are coalescing binary black hole systems. They can occur on all mass scales and be formed in numerous ways, many of which are not understood. They are generally invisible in electromagnetic waves, and they provide opportunities for deep investigation of Einstein's general theory of relativity. Sect. 1 of this paper considers ways that binary black holes can be created in the universe, and includes the prediction that binary black hole coalescence events are likely to be the first gravitational wave sources to be detected. The next parts of this paper address the detection of chirp waveforms from coalescence events in noisy data.Such analysis is computationally intensive. Sect. 2 reviews a new and powerful method of signal detection based on the GPUimplemented summed parallel infinite impulse response filters. Such filters are intrinsically real time alorithms, that can be used to rapidly detect and localise signals. Sect. 3 of the paper reviews the use of GPU processors for rapid searching for gravitational wave bursts that can arise from black hole births and coalescences. In sect. 4 the use of GPU processors to enable fast efficient statistical significance testing of gravitational wave event candidates is reviewed. Sect. 5 of this paper addresses the method of multimessenger astronomy where the discovery of electromagnetic counterparts of gravitational wave events can be used to identify sources, understand their nature and obtain much greater science outcomes from each identified event. | LEE Hyung Mok LE BIGOT Eric-Olivier DU ZhiHui LIN ZhangXi GUO XiangYu WEN LinQing PHUKON Khun Sang PANDEY Vihan BOSE Sukanta FAN Xi-Long HENDRY Martin | 2015 | Science China(Physics,Mechanics & Astronomy)2015，58，12： | 5 |

| 4 | 基于链接结构分析的主题搜索显示文摘针对目前一般文本搜索引擎采用的关键词匹配方法导致搜索效率相对低下的问题,在分析语义相关性的度量方案基础上,利用Wikipedia丰富链接结构所蕴涵信息,提出基于链接结构分析的主题搜索策略.设计了词条相关性算法,用以描述词间距离,并对词条进行相关度的重新排序.实验中引入用户评价机制,并与传统策略搜索结果进行对比.结果证明,该策略在扩大主题覆盖度的同时保证了较高的用户意图识别度. | 余旸 Zhangxi LIN 夏国平 | 2011 | 北京工业大学学报2011，37，4： | 2 |
| 5 | PicoRio:An Open-Source,RISC-V Small-Board Computer to Elevate the RISC-V Software Ecosystem显示文摘PicoRioTM is an open-source project stewarded by the RISC-V International Open Source(RIOS)laboratory—rioslab.org—a nonprofit research lab at Tsinghua-Berkeley Shenzhen Institute(TBSI).The RIOS Lab uses collaborative engineering from both academia and industry to elevate the RISC-V software and hardware ecosystem.In Pico Rio,we create an open,affordable,Linux-capable RISC-V hardware platform to aid software developers in porting many modern programs that require Javascript or GPUs.Pico Rio will build upon high-quality IPs and software components from expert industry engineers and academic researchers.Pico Rio is not proprietary to any specific vendor and platform,and will have complete documentation that can help people to build quality products in a short amount of time.Our plan is to ship Pico Rio 1.0 in 1H2021. | Zhangxi Tan Lin Zhang David Patterson Yi Li | 2021 | Tsinghua Science and Technology2021，26，3： | 1 |

| 17 | 开放内容空间的Spam页面侦测显示文摘基于链接分析自动侦测Spam页面,提出了一个分阶段机制。采用决策树和链接分析模型对Wikipedia中的所有节点进行Indegree和Outdegree检测,从而产生出一个候选列表,并引入一个启发算法来降低第一类型的错误。设计一个分类器用于分类候选列表,采用TrustRank和SpamRank算法分别从信任种子集和Spam种子集中推算系统页面各自可信概率和Spam概率,从而减少第二类型的错误。然后将产生的候选集合推送至页面编辑,根据编辑判断的结果反馈训练模型,调整权重。结果表明,分阶段侦测模型可自动地侦测Spam页面,其查准率和查全率分别达到78.3%和94%。 | 余旸 Lin Zhangxi 夏国平 | 2009 | 武汉科技大学学报2009，32，2： | 0 |
| 18 | Vitamin B_(12)-auxotrophy in dinoflagellates caused by incomplete or absent cobalamin-independent methionine synthase genes(metE)显示文摘Dinoflagellates are responsible for most marine harmful algal blooms (HABs) and play vital roles in many ocean processes.More than 90% of dinoflagellates are vitamin B_(12) auxotrophs and that B_(12) availability can control dinoflagellate HABs,yet the genetic basis of B_(12) auxotrophy in dinoflagellates in the framework of the ecology of dinoflagellates and particularly HABs,which was the objective of this work.Here,we investigated the presence,phylogeny,and transcription of two methionine synthase genes(B_(12)-dependent metH and B_(12)-independent metE)via searching and assembling transcripts and genes from transcriptomic and genomic databases,cloning 38 cDNA isoforms of the two genes from 14 strains of dinoflagellates,measuring the expression at different scenarios of B_(12),and comprehensive phylogenetic analyses of more than 100 organisms.We found that 1)metH was present in all 58 dinoflagellates accessible and metE was present in 40 of 58 species,2)all metE genes lacked N-terminal domains,3)metE of dinoflagellates were phylogenetically distinct from other known metE genes,and 4)expression of metH in dinoflagellates was responsive to exogenous B_(12) levels while expression of metE was not responding as that of genuine metE genes.We conclude that most,hypothetically all,dinoflagellates have either non-functional metE genes lacking N-terminal domain for most species,or do not possess metE for other species,which provides the genetic basis for the widespread nature of B_(12) auxotrophy in dinoflagellates.The work elucidated a fundamental aspect of the nutritional ecology of dinoflagellates. | Siheng Lin Zhangxi Hu Xiaoying Song Christopher JGobler Ying Zhong Tang | 2022 | Fundamental Research2022，2，5： | 0 |
| 19 | Expected return,time-varying risk,and hedging demand in the US REITs market显示文摘This paper explores the time-varying relationship between the return and risk for the portfolios in the US real estate investment trusts(REITs)market.Three classes of REITs portfolios are sorted on size,momentum and book-to-market.The empirical results place a positive trade-off between the return and predictable covariation in all REITs portfolios.Furthermore,this paper examines the significance of intertemporal hedging demand in each REITs portfolio by extending the Intertemporal Capital Asset Pricing model(ICAPM)with a set of prevailing macroeconomic variables and financial market indicators,which indicate that the predictable movements in return could be attributed to the change in covariances with these innovations.The conclusive results show that innovations in inflation rate,de-trended short-term interest rate,Fama-French momentum factor,S&P/Case-Shiller home price index,and Barclay Capital long-term government/corporate bond index play a crucial role in hedging demand for REITs portfolios. | Zhongyi Xiao Zhangxi Lin Siming Li | 2014 | Journal of Management Analytics2014，1，1： | 0 |
