| 1 | Analysis and outlook of applications of blockchain technology to equity crowdfunding in China显示文摘Equity crowdfunding via the Internet is a new channel of raising money for startups.It features low barriers to entry,low cost,and high speed,and thus encourages innovation.In recent years,equity crowdfunding in China has experienced some developments.However,some problems remain unsolved in practice.Blockchain is a decentralized and distributed ledger technology to ensure data security,transparency,and integrity.Because it cannot be tampered with or forged,the technology is deemed to have great potential in the finance industry.This study examines current problems in the practice of equity crowdfunding in China.Based on the analysis of the characteristics of blockchain technology,this study further explores its practical applications in equity crowdfunding.1)Blockchain technology may be a secure,efficient,low-cost solution for the registration of stocks and shares of a firm financed by crowdfunding;2)Blockchain technology simplifies the transaction and transfer of crowdfunding equities,and thus facilitates their circulation;3)Blockchain technology enables peer to peer transactions between investors and entrepreneurs,and solves the problems of regulatory compliance and security of fund management;Blockchain technology can be used to develop a voting system for crowdfunders,which enables them to be involved in corporate governance.This helps protect the rights and interests of small investors;5)Blockchain technology helps regulators know about market conditions,and supports regulatory activities such as managing investors and fighting money laundering. | Huasheng Zhu Zach Zhizhong Zhou | 2016 | Financial Innovation2016，2，1： | 15 |
| 2 | Towards multiple hazard resilient bridges:a methodology for modeling frequent and infrequent time-varying loads Part I,Comprehensive reliability and partial failure probabilities显示文摘The current AASHTO load and resistance factor design (LRFD) guidelines are formulated based on bridge reliability,which interprets traditional design safety factors into more rigorously deduced factors based on the theory of probability.This is a major advancement in bridge design specifications.However,LRFD is only calibrated for dead and live loads.In cases when extreme loads are significant,they need to be individually assessed.Combining regular loads with extreme loads has been a major challenge,mainly because the extreme loads are time variables and cannot be directly combined with time invariant loads to formulate the probability of structural failure.To overcome these difficulties,this paper suggests a methodology of comprehensive reliability,by introducing the concept of partial failure probability to separate the loads so that each individual load combination under a certain condition can be approximated as time invariant.Based on these conditions,the extreme loads (also referred to as multiple hazard or MH loads) can be broken down into single effects.In Part Ⅱ of this paper,a further breakdown of these conditional occurrence probabilities into pure conditions is discussed by using a live truck and earthquake loads on a bridge as an example.There are three major steps in establishing load factors from MH load distributions:(1) formulate the failure probabilities;(2) normalize various load distributions;and (3) establish design limit state equations.This paper describes the formulation of the failure probabilities of single and combined loads. | Zach Liang George C.Lee | 2012 | Earthquake Engineering and Engineering Vibration2012，11，3： | 8 |

| 5 | Bridge pier failure probabilities under combined hazard effects of scour, truck and earthquake. Part Ⅰ: occurrence probabilities显示文摘In many regions of the world, a bridge will experience multiple extreme hazards during its expected service life. The current American Association of State Highway and Transportation Officials (AASHTO) load and resistance factor design (LRFD) specifications are formulated based on failure probabilities, which are fully calibrated for dead load and non- extreme live loads. Design against earthquake loads is established separately. Design against scour effect is also formulated separately by using the concept of capacity reduction (or increased scour depth). Furthermore, scour effect cannot be linked directly to an LRFD limit state equation, because the latter is formulated using force-based analysis. This paper (in two parts) presents a probability-based procedure to estimate the combined hazard effects on bridges due to truck, earthquake and scour, by treating the effect of scour as an equivalent load effect so that it can be included in reliability-based bridge failure calculations. In Part I of this series, the general principle of treating the scour depth as an equivalent load effect is presented. The individual and combined partial failure probabilities due to truck, earthquake and scour effects are described. To explain the method of including non-force-based natural hazards effects, two types of common scour failures are considered. In Part II, the corresponding bridge failure probability, the occurrence of scour as well as simultaneously having both truck load and equivalent scour load are quantitatively discussed. | Zach Liang George C.

| 6 | Analysis of coal pillar stability(ACPS): A new generation of pillar design software显示文摘Thirty years ago, the analysis of longwall pillar stability(ALPS) inaugurated a new era in coal pillar design.ALPS was the first empirical pillar design technique to consider the abutment loads that arise from full extraction, and the first to be calibrated using an extensive database of longwall mining case histories.ALPS was followed by the analysis of retreat mining stability(ARMPS) and the analysis of multiple seam stability(AMSS). These methods incorporated other innovations, including the coal mine roof rating(CMRR), the Mark-Bieniawski pillar strength formula, and the pressure arch loading model. They also built upon ever larger case history databases and employed more sophisticated statistical methods.Today, these empirical methods are used in nearly every underground coal mine in the US. However,the piecemeal manner in which these methods have evolved resulted in some weaknesses. For example,in certain situations, it may not be obvious which program is the best to use. Other times the results from the different programs are not entirely consistent with each other. The programs have also not been updated for several years, and some changes were necessary to keep pace with new developments in mining practice. The analysis of coal pillar stability(ACPS) now integrates all three of the older software packages into a single pillar design framework. ACPS also incorporates the latest research findings in the field of pillar design, including an expanded multiple seam case history data base and a new method to evaluate room and pillar panels containing multiple rows of pillars left in place during pillar recovery.ACPS also includes updated guidance and warnings for users and features upgraded help files and graphics. | Christopher Mark Zach Agioutantis | 2019 | International Journal of Mining Science and Technology2019，29，1： | 5 |
| 7 | Development of a new algorithm for implementing the edge effect offset for subsidence calculations显示文摘The surface deformation prediction system(SDPS) program has been developed as an engineering tool for the calculation of subsidence deformation indices through the implementation of various prediction methods.From basic user-defined input parameters, SDPS can determine subsidence indices, such as mining induced displacements, strains, tilt, etc., at any elevation between the seam and the horizontal or varying surface topography.A fundamental parameter in obtaining reliable ground deformation results is the determination of the edge effect offset.The value assigned to the edge effect offset corresponds to a virtual offsetting of boundary lines delineating the extracted panel to allow for roof cantilevering over the mined-out area.The objective of this paper is to describe the methods implemented in updating the edge effect offset algorithm within SDPS.Using proven geometric equations, the newly developed algorithm provides a more robust calculation of the offset boundary of the extracted panel for simplistic as well as more complex mining geometries.Given that an extracted panel is represented by a closed polyline, the new edge offset algorithm calculates a polyline offset into the extracted panel with respect to the user defined edge effect offset distance.Surface deformations are then calculated using this adjusted panel geometry.The Matlab program was utilized for development and testing of the new edge effect offset algorithm.After completing rigorous testing regimes, the new offset algorithm will be integrated into SDPS further increasing the speed and reliability of the program resulting in a retrospective increase in capability and flexibility. | Joshua Hescock Christopher Newman Zach Agioutantis | 2018 | International Journal of Mining Science and Technology2018，28，1： | 4 |
| 8 | Stem cells, growth factors and scaffolds in craniofacial regenerative medicine显示文摘Current reconstructive approaches to large craniofacial skeletal defects are often complicated and challenging.Critical-sized defects are unable to heal via natural regenerative processes and require surgical intervention,traditionally involving autologous bone(mainly in the form of nonvascularized grafts)or alloplasts.Autologous bone grafts remain the gold standard of care in spite of the associated risk of donor site morbidity.Tissue engineering approaches represent a promising alternative that would serve to facilitate bone regeneration even in large craniofacial skeletal defects.This strategy has been tested in a myriad of iterations by utilizing a variety of osteoconductive scaffold materials,osteoblastic stem cells,as well as osteoinductive growth factors and small molecules.One of the major challenges facing tissue engineers is creating a scaffold fulfilling the properties necessary for controlled bone regeneration.These properties include osteoconduction,osteoinduction,biocompatibility,biodegradability,vascularization,and progenitor cell retention.This review will provide an overview of how optimization of the aforementioned scaffold parameters facilitates bone regenerative capabilities as well as a discussion of common osteoconductive scaffold materials. | Viktor Tollemar Zach J.Collier Maryam K.Mohammed Michael J.Lee Guillermo A.Ameer Russell R.Reid | 2016 | Genes & Diseases2016，3，1： | 3 |

| 12 | Towards establishing practical multi-hazard bridge design limit states显示文摘In the U.S.,the current Load and Resistance Factor Design(LRFD) Specifications for highway bridges is a reliability-based formulation that considers failure probabilities of bridge components due to the actions of typical dead load and frequent vehicular loads.Various extreme load effects,such as earthquake and vessel collision,are not considered on the same reliability-based platform.Since these extreme loads are time variables,combining them with frequent,nonextreme loads is a significant challenge.The number of design limit state equations based on these failure probabilities can be unrealistically large and unnecessary from the view point of practical applications.Based on the opinion of AASHTO State Bridge Engineers,many load combinations are insignificant in their states.This paper describes the formulation of a criterion to include only the necessary load combinations to establish the design limit states.This criterion is established by examining the total failure probabilities for all possible time-invariant and time varying load combinations and breaking them down into partial terms.Then,important load combinations can be readily determined quantitatively. | Zach Liang George C.Lee | 2013 | Earthquake Engineering and Engineering Vibration2013，12，3： | 2 |

| 14 | Motivation dimensions for running a marathon:A new model emerging from the Motivation of Marathon Scale(MOMS)显示文摘Purpose:The aim of this study was to test and expand the Motivation of Marathoners Scale(MOMS) model(Masters et al.,1993).Methods:The MOMS questionnaire was distributed to 306 male and female marathon runners(age range:20–77 years) with experience in marathon running(range:1–44 runs).A confirmatory factor analysis(CFA) revealed that the original model failed to fit the data.Hence,exploratory factor analysis(EFA) was performed to test the best factorial solution for the current data,and a subsequent CFA was performed on the revised factorial structure.Then,a series of EFAs using maximum likelihood factor extraction method were performed.Results:The best structure solution for model-data fit resulted in 11 factors:psychological coping—emotional-related coping,psychological coping—everyday-life management,life meaning,self-esteem,recognition,affiliation,weight concerns,general health orientation—reduced disease prevalence and longevity,general health orientation—keep fit,competition,and personal goal achievement.Conclusion:This study provides a sound and solid framework for studying motivation for physically demanding tasks such as marathon runs,and needs to be similarly applied and tested in studies incorporating physical tasks which vary in mental demands. | Sima Zach Yan Xia Aviva Zeev Michal Arnon Noa Choresh Gershon Tenenbaum | 2017 | Journal of Sport and Health Science2017，6，3： | 2 |
