| 1 | Discussion on the relationship between the Yanshanian Movement and cratonic destruction in North China显示文摘The relationship between the Yanshanian Movement, destruction of the North China Craton(NCC), and subduction of the western Pacific plate is crucial to reconstructing the middle-late Mesozoic tectonic evolution of the eastern Asian continent and margin. The Yanshanian Movement was a globally important change in crustal tectonics during the Middle-Late Jurassic.Previous research has systematically studied the formation and evolution of the Yanshanian Movement, focusing on the timing and location of tectonic movements, and the sedimentary and volcanic strata. However, the question of whether the tectonic activity occurred globally, and the characteristics of the Yanshanian Movement remain debated. The main argument is that if a tectonic movement can only be characterized by a regional or local disconformity, and if the tectonic movement occurred in an intracontinental setting, with extensive deformation but with no disconformity despite volcanic eruptions and magmatic intrusions, accompanied by changes in crustal structure and composition, should it be defined as a tectonic event or process? This question requires further analysis. The main aim of this study is to distinguish whether the Yanshanian Movement is a local feature of the eastern Asian continent, or a global tectonic event related to subduction of the Pacific Plate. In this paper, based on previous research, we discuss the spatial and temporal evolution of the Yanshanian Movement, the controlling tectonic mechanisms, and its relationship to the reactivation and destruction of the NCC and the subduction of the western Paleo-Pacific slab.We emphasize that the Yanshanian Movement in the Middle-Late Jurassic is distinct from the lithospheric thinning responsible for Early Cretaceous extension and magmatism related to the destruction of the NCC. The various tectonic stages were constrained by different dynamics and tectonic settings, or by different tectonic events and processes. Therefore, it is possible that the deformation and reactivation of the NCC contributed to its destruction, in addition to lithospheric thinning. Finally, we discuss whether the Yanshanian Movement was associated with the destruction of the NCC. | Yu WANG Lixin SUN Liyun ZHOU Yueting XIE | 2018 | Science China Earth Sciences2018，61，5： | 13 |
| 2 | Benign prostatic hyperplasia and male lower urinary symptoms:A guide for family physicians显示文摘Male patients with lower urinary tract symptoms(LUTS)and benign prostatic hyperplasia(BPH)are increasingly seen by family physicians worldwide due to ageing demographics.A systematic way to stratify patients who can be managed in the community and those who need to be referred to the urologist is thus very useful.Good history taking,physical examination,targeted blood or urine tests,and knowing the red flags for referral are the mainstay of stratifying these patients.Case selection is always key in clinical practice and in the setting of the family physician.The best patient to manage is one above 40 years of age,symptomatic with nocturia,slower stream and sensation of incomplete voiding,has a normal prostatespecific antigen level,no palpable bladder,and no haematuria or pyuria on the labstix.The roles of α blockers,5-α reductase inhibitors,and antibiotics in a primary care setting to manage this condition are also discussed. | Farhad Fakhrudin Vasanwala Michael Yuet Chen Wong Henry Sun Sien Ho Keong Tatt Foo | 2017 | Asian Journal of Urology2017，4，3： | 5 |
| 3 | Evolution of Specialization with Reachable Transaction Scope Based on a Simple and Symmetric Firm Resource Allocation Model显示文摘In the last decade, as an emerging transaction measure driven by computer and internet technology,e-commerce experienced explosive growth in many areas. It has greatly broken down the limitations of space and time to economic activities, thus changing the rules of business fundamentally. Significant work has been done to understand the laws of e-commerce from multiple dimensions, but the question of how e-commerce shapes firms' specialization and market structure from the perspective of spatial factors remains obscure. In this paper, we propose a simple and symmetric firm resource allocation model with a specialized-economy production function and market size constraint, to investigate how individual firms adjust resource allocation with reachable transaction scope expanded. It is shown that with the expansion of reachable transaction scope, individual firms discretely take back one unit resource from a low-investment direction and, instead, channel it to a 'specialized direction'.Meanwhile, at the macro level, an optimal division network evolves from a static self-sufficient stage to a diverse semi-specialized stage, and finally to a highly integrated completely specialized stage. Ergo, a Complex Adaptive System(CAS) based simulation framework is constructed. Designed simulation experiments are carried out and confirm to the analysis result of our proposed model. | Xiao Sun Yueting Chai Yi Liu Jianping Shen Yadong Huang | 2017 | Tsinghua Science and Technology2017，22，1： | 2 |

| 6 | Interfacial behavior of Fe_(76)Si_9B_(10)P_5/Zn_(0.5)Ni_(0.5)Fe_2O_4 amorphous soft magnetic composite during spark plasma sintering process显示文摘Fe_(76)Si_9B_(10)P_5/Zn_(0.5)Ni_(0.5)Fe_2O_4 amorphous composite with micro-cellular structure and high electrical resistivity was prepared by spark plasma sintering(SPS) at 487 °C. XRD and SEM results showed that the Fe_(76)Si_9B_(10)P_5 alloy powders remained the amorphous state and the composite was dense. A fusion zone at interface of Fe_(76)Si_9B_(10)P_5 cell body and Zn_(0.5)Ni_(0.5)Fe_2O_4 cell wall was observed by TEM, which also indicates the formation of local high temperature. The interface bonding based on the formation of local high temperature in SPS process was observed. It is believed that the tip effect of Zn_(0.5)Ni_(0.5)Fe_2O_4 nanoparticles promotes the local discharging and plasmas creation in the gaps, and the discharging energy forms an instantaneous local high temperature to complete the local sintering and the densification of Zn_(0.5)Ni_(0.5)Fe_2O_4 particles at a low nominal sinter temperature. Simultaneously, the local high temperature stimulates the adjacent gaps discharging, thus facilitate the continuous formation of new discharging path. Finally, sintering and densification of the amorphous composite is complete. | Zhankui Zhao Yueting Sun Minggang Wang Yue Chi Hongli Wang | 2016 | Progress in Natural Science:Materials International2016，26，1： | 1 |
| 7 | Genome-Wide Exploration of the Grape GLR Gene Family and Differential Responses of VvGLR3.1 and VvGLR3.2 to Low Temperature and Salt Stress显示文摘Grapes,one of the oldest tree species globally,are rich in vitamins.However,environmental conditions such as low temperature and soil salinization significantly affect grape yield and quality.The glutamate receptor(GLR)family,comprising highly conserved ligand-gated ion channels,regulates plant growth and development in response to stress.In this study,11 members of the VvGLR gene family in grapes were identified using whole-genome sequence analysis.Bioinformatic methods were employed to analyze the basic physical and chemical properties,phylogenetic trees,conserved domains,motifs,expression patterns,and evolutionary relationships.Phylogenetic and collinear analyses revealed that the VvGLRs were divided into three subgroups,showing the high conservation of the grape GLR family.These members exhibited 2 glutamate receptor binding regions(GABAb and GluR)and 3-4 transmembrane regions(M1,M2,M3,and M4).Real-time quantitative PCR analysis demonstrated the sensitivity of all VvGLRs to low temperature and salt stress.Subsequent localization studies in Nicotiana tabacum verified that VvGLR3.1 and VvGLR3.2 proteins were located on the cell membrane and cell nucleus.Additionally,yeast transformation experiments confirmed the functionality of VvGLR3.1 and VvGLR3.2 in response to low temperature and salt stress.Thesefindings highlight the significant role of the GLR family,a highly conserved group of ion channels,in enhancing grape stress resistance.This study offers new insights into the grape GLR gene family,providing fundamental knowledge for further functional analysis and breeding of stress-resistant grapevines. | Honghui Sun Ruichao Liu Yueting Qi Hongsheng Gao Xueting Wang Ning Jiang Xiaotong Guo Hongxia Zhang Chunyan Yu | 2024 | Phyton-International Journal of Experimental Botany2024，93，3： | 0 |
| 8 | Infra-Marginal Analysis Model for Provision Mode Selection for E-commerce Services显示文摘E-commerce has grown extraordinarily since the emergence of the internet,and many types of services are employed to accelerate this process. Service quality and productivity are two critical indicators to evaluate the competitiveness of e-commerce companies. Deciding which provision mode of e-commerce services(buy,sell,or self-provide) to adopt is a key operational strategy issue. This paper investigates the conditions and limitations of e-commerce services' optimal supply modes,and proposes a cost oriented infra-marginal model where service demand is considered an exogenous variable due to its non-elastic and unprofitable characteristics. By analyzing the main impact factors of this model,this paper infers provision mode selection strategies,which are determined by four factors: transaction cost,service price,service demand,and competitive advantages. Decision trees are derived from these strategies to help e-commerce companies make appropriate decisions. Finally,the proposed model's feasibility is verified by two case studies. | Xiao Yu Yueting Chai Yi Liu Hongbo Sun | 2014 | Tsinghua Science and Technology2014，19，2： | 0 |
| 9 | Nonlinear dynamic response and stability analysis of the stapes reconstruction in human middle ear显示文摘Stapes fracture causes hearing loss and instability in the middle ear hearing system(MEHS). The material used in the stapes reconstruction restores stapes, but the effects of the nonlinear material parameters on the stability of the MEHS are still unknown. To address this challenge, the nonlinear dynamic response and stability of the stapes reconstruction are investigated using a multi-degree-of-freedom mechanical model. The material parameters of the implant are tentatively determined by analyzing the natural frequencies of the undamped system. The dynamical properties of the MEHS are characterized under different external excitations. The approximate solution of the MEHS near the resonant frequency is derived through the multiple-time-scale method(MTSM). The results show that the nonlinear stiffness of the material has little influence on the MEHS in the healthy state, but it causes resonant phenomena between the ossicle and the implant in the pathological state. | Lele WANG Liang WANG Yueting ZHU Zhanli LIU Yongtao SUN Jie WANG Hongge HAN Shuyi XIANG Huibin SHI Qian DING | 2023 | Applied Mathematics and Mechanics(English Edition)2023，44，10： | 0 |

| 11 | Analysis of a Firm's Optimal Size Based on Accessible Market Capacity显示文摘E-commerce has dramatically reduced the limitation of space and time on economic activities,resulting in individuals having access to a huge number of consumers.In this paper,we propose a company's optimal size decision model containing management costs as a means of investigating the evolution of the company size in e-commerce.Given that production decisions are made based on accessible market capacity,we explain how a company enters the market,and we draw an evolutionary path of the optimal company size.The results show that in the early expansion stage of accessible market capacity,a firm's optimal size keeps increasing;after reaching a peak,the change in a firm's optimal size depends on its cost management.When the accessible market capacity reaches a threshold,the firm will no longer be in the market,and may no longer exist.Finally,we construct a simulation framework based on complex adaptive systems to validate our proposed model.A simulation experiment confirms our model and reveals the dynamic co-evolution process of individual producers and firms. | Xiao Sun Jun Qian Yueting Chai Yi Liu | 2020 | Tsinghua Science and Technology2020，25，5： | 0 |
