1利用DEM提取地貌指数的方法述评显示文摘介绍了几个广泛应用于水文科学的流域地貌指数(包括地表坡度、流量分配系数、单宽集水面积、集水面积以及湿度指数)的计算方法,阐述了这些地貌指数在水文科学中所代表的物理意义和对流域水文过程空间分布的描述能力。对了解流域地貌对降雨径流的影响,揭示产汇流过程的物理机制,研制和开发分布式水文物理模型均有重要意义。熊立华 郭生练 Kieran M.O Connor 2002水科学进展2002,13,6:30
2Recent advances and strategies in the stabilization of single-atom catalysts for electrochemical applications显示文摘Owing to the rapidly increasing consumption of fossil fuels,finding clean and reliable new energy sources is of the utmost importance.Thus,developing highly efficient and low-cost catalysts for electrochemical reactions in energy conversion devices is crucial.Single-atom catalysts(SACs)with maximum metal atom utilization efficiency and superior catalytic performance have attracted significant attention,especially for electrochemical reactions.However,because of the highly unsaturated coordination environment,the stability of SACs can be a challenge for practical applications.In this review,we will summarize the strategies to increase the stability of SACs and synthesizing stable SACs,as well as the application of SACs in electrochemical reactions.Finally,we offer a perspective on the development of advanced SACs through rational design and a deeper understanding of SACs with the help of in situ or operando techniques in electrochemical reactions.Junjie Li Lei Zhang Kieran Doyle-Davis Ruying Li Xueliang Sun 2020Carbon Energy2020,2,4:9

4Liver transplantation and multivisceral transplantation in the management of patients with advanced neuroendocrine tumours显示文摘Orthotopic liver transplantation(OLT) represents a generally accepted albeit somewhat controversially discussed therapeutic strategy in highly selected patients with non-resectable hepatic metastases from neuroendocrine tumours(NET). Whilst there are some exclusion criteria, these are not universally followed, and the optimal set of inclusion parameters for deeming patients eligible has not yet been elucidated. This is due to heterogeneity in the study populations, as well differing approaches employed and also divergences in selection criteria between centres. Recent data have suggested that OLT may represent the most efficacious approach in terms of overall and disease-free survival to the management of NET metastatic to the liver when conducted in accordance with the modified Milan criteria. Therefore, a consensus set of selection criteria requires definition to facilitate stringent and fair allocation of deceased-donor organs, as well as consideration for living-donor organs. In the context of classically non-resectable metastatic tumour bulk, multivisceral transplantation with or without the liver may also be indicated, yet experience is very limited. In this review, we discuss the diagnostic work-up of patients in whom the aforementioned transplantation approaches are being considered, critically analyse the published experience and also anticipate future developments in this field, including a discussion of immediate and longer-term research priorities.Ashley Kieran Clift Andrea Frilling 2018World Journal of Gastroenterology2018,24,20:5
5The application of carbon materials in nonaqueous Na‐O2 batteries显示文摘Na‐O2 batteries are advantageous as the candidates of next‐generation electric vehicles due to their ultrahigh theoretical energy density and have attracted enormous attention recently.Tremendous efforts have been devoted to improve the Na‐O2 battery performance by designing advanced electrodes with various carbonbased materials.Carbon materials used in Na‐O2 batteries not only function as the air electrode to provide active sites and accommodate discharge products but also as Na anode protectors against dendrite growth and chemical/electrochemical corrosion.In this review,we mainly focus on the application of various carbonbased materials in Na‐O2 batteries and highlight their advances.The scientific understanding on the fundamental design of the material microstructure and chemistry in relation to the battery performance are summarized.Finally,perspectives on enhancing the overall battery performance based on the optimization and rational design of carbon‐based cell components are also briefly anticipated.Xiaoting Lin Qian Sun Kieran Doyle Davis Ruying Li Xueliang Sun 2019Carbon Energy2019,1,2:5
6Controversies in the pathological assessment of colorectal cancer显示文摘Pathologic assessment of colorectal cancer specimens plays an essential role in patient management,informing prognosis and contributing to therapeutic decision making.The tumor-node-metastasis(TNM)staging system is a key component of the colorectal cancer pathology report and provides important prognostic information.However there is significant variation in outcome of patients within the same tumor stage.Many other histological features such as tumor budding,vascular invasion,perineural invasion,tumor grade and rectal tumor regression grade that may be of prognostic value are not part of TNM staging.Assessment of extramural tumor deposits and peritoneal involvement contributes to TNM staging but there are some difficulties with the definition of both of these features.Controversies in colorectal cancer pathology reporting include the subjective nature of some of the elements assessed,poor reporting rates and reproducibility and the need for standardized examination protocols and reporting.Molecular pathology is becoming increasingly important in prognostication and prediction of response to targeted therapies but accurate morphology still has a key role to play in colorectal cancer pathology reporting.Aoife Maguire Kieran Sheahan 2014World Journal of Gastroenterology2014,20,29:5

9Tectonic Implications and Petrogenesis of the Various Types of Magmatic Rocks from the Zedang Area in Southern Tibet显示文摘In this study,we report systematically field observations,geochronology,whole-rock geochemistry and Sr-Nd-Hf isotopic dataset on the various types of magmatic rocks collected from the Zedang area.Chemically,the diabase and gabbro have a low-K calc-alkaline affinity,whereas the basalt and plagiogranite have medium to high-K calc-alkaline characteristics.In addition,the basalts are highly enriched in light rare earth elements(LREE)and large ion lithophile elements(LILE),but strongly depleted in high strength field elements(HFSE),indicating that their magma source probably was derived from a subduction-or arc-related setting.In contrast,both the gabbro and diabase mainly demonstrate an N-MORB-like affinity consistent with normal mid-oceanic ridge basalt(N-MORB)origin.The zircon U-Pb dating results suggest that the basalts were crystallized earlier at ca.158–161 Ma(Oxfordian stage),but the gabbro was crystallized at ca.131 Ma(Hauterivian stage of Early Cretaceous).The zircon U-Pb dating results correspond with the field observations that the veins of gabbro intruded basalt.Furthermore,the plagiogranite has a weighted mean age of ca.160 Ma(MSWD=2.1)consistent with the basalt within the uncertainty.The basalt and the plagiogranite have significantly positiveεHf(t)values(+5.8 to+15.6 and+8.6 to+16.1,respectively),suggesting that they were originated from partial melting of a depleted source.However,basalt and plagiogranite are characterized by the wide variations ofεHf(t)values indicating minor amounts of exotic crustal material input during the later magma evolution.Additionally,the basalt shows duplex geochemical features of island-arc and mid-oceanic ridge basalt,corresponding to the supra-subduction zone-(SSZ)type affinity.To sum up,two distinct magmatic events identified in this study probably suggest an intra-oceanic arc system existing in the Zedang area during the Late Jurassic,but the intra-oceanic arc subduction extinguished in the Early Cretaceous as suggested by the N-MORB-like gabbro and diabase.Integrated with regional background and different rock types,as well as geochemical features,we conclude that intra-oceanic arc subduction setting developed during the Late Jurassic in the Zedang area,southern Tibet.Yuanku Mengc Fahui Xiong Jingsui Yang Zhao Liu Kieran AIles Paul TRobinson Xiangzhen Xu 2019Journal of Earth Science2019,30,6:2
