1Assimilation of carbonate country rock by the parent magma of the Panzhihua Fe-Ti-V deposit(SW China):Evidence from stable isotopes显示文摘在西南中国的 Panzhihua 侵入是 Emeishan 大火的省的部分和大 Fe-Ti-V 矿石存款的主人。在主要侵入的炮兵阵地期间, mafic 女同性恋的多重代入侵了碳酸盐墙岩石,生产一个大接触光环。我们测量了国家岩石的侵入,他们的成分矿物质,和样品的氧同位素作文。从 Panzhihua 侵入的磁铁矿和斜长石有与 magmatic 平衡一致,并且比在导出披风的岩浆期望与高是 12 的 18O 价值从岩浆形成的 18O 价值。unmetamorphosed 国家岩石有高 18O 价值,从 13.2 (沙岩) 到 24.628.6 (白云石) 。从光环的 skarns 和云石比他们与在有邻近的 mafic 岩浆和侵入的特别众多的 mafic 女同性恋的交换平衡的液体建议相互作用的 protolith 有更低的 18O 和 13C 价值光环。这将比为导出披风的岩浆期望解释有显著地更高的价值的女同性恋的 18O 的改变。取决于为岩浆和沾染物假定的准确 18O 价值,要求生产 Panzhihua 侵入的提高的 18O 价值的吸收的数量在 8 和 13.7 wt.% 之间,假定简单混合。污染的准确机制是不清楚的,但是可以包含体积国家岩石的吸收的联合,混合与一有 CO2 富有的液体的国家岩石和交换的 melt 源于泥土和白云石的 decarbonation。这些机制,特别地后者,可能涉及 Fe-Ti-V 矿石的形成。Clement Ganino Chris Harris Nicholas T.Arndt Stephen A.Prevec Geoffrey H.Howarth 2013Geoscience Frontiers2013,4,5:20
2The GWmodel R package:further topics for exploring spatial heterogeneity using geographically weighted models显示文摘In this study,we present a collection of local models,termed geographically weighted(GW)models,which can be found within the GWmodel R package.A GW model suits situations when spatial data are poorly described by the global form,and for some regions the localized fit provides a better description.The approach uses a moving window weighting technique,where a collection of local models are estimated at target locations.Commonly,model parameters or outputs are mapped so that the nature of spatial heterogeneity can be explored and assessed.In particular,we present case studies using:(i)GW summary statistics and a GW principal components analysis;(ii)advanced GW regression fits and diagnostics;(iii)associated Monte Carlo significance tests for non-stationarity;(iv)a GW discriminant analysis;and(v)enhanced kernel bandwidth selection procedures.General Election data-sets from the Republic of Ireland and US are used for demonstration.This study is designed to complement a companion GWmodel study,which focuses on basic and robust GW models.Binbin LU Paul HARRIS Martin CHARLTON Chris BRUNSDON 2014Geo-Spatial Information Science2014,17,2:9
3针对患者利益的机器学习和人工智能研究:在透明性、可重复性、伦理和有效性等方面的20个关键问题显示文摘机器学习(ML)、人工智能(AI)和其他现代统计方法正为利用先前尚未开发且极速增长的数据资源提供新的机会,以期让患者获益。尽管目前正在进行许多有前景的研究,特别是在图像方面,但就文献整体而言还缺乏透明度、对可重复性清晰的阐述、对潜在伦理问题的探究,以及对有效性的明确验证。这些问题的存在有许多原因,其中最重要的一点(为此我们提供了初步解决方案)就是当前缺乏针对ML和AI的最佳实践指南。我们认为从事研究的跨学科团队和应用ML/AI影响健康的项目,将因解决有关透明度、可重复性、伦理和有效性(TREE)的一系列问题而受益。这里提出的20个关键问题为研究团队提供了一个研究设计、实施和报告框架;帮助编辑和同行评审专家评估文献的贡献;让患者、临床医生和政策制定者评估新发现可能会给患者带来的获益。Sebastian Vollmer Bilal A Mateen Gergo Bohner Franz J Kirdly Rayid Ghani Pall Jonsson Sarah Cumbers Adrian Jonas Katherine S L McAllister Puja Myles David Granger Mark Birse Richard Branson Karel G M Moons Gary S Collins John P A Chris Holmes Harry Hemingwayp 李峰(译) 徐磊(校) 赵邑(校) 2020英国医学杂志中文版2020,23,9:5
4A history of high-power laser research and development in the United Kingdom显示文摘The first demonstration of laser action in ruby was made in 1960 by T.H.Maiman of Hughes Research Laboratories,USA.Many laboratories worldwide began the search for lasers using different materials,operating at different wavelengths.In the UK,academia,industry and the central laboratories took up the challenge from the earliest days to develop these systems for a broad range of applications.This historical review looks at the contribution the UK has made to the advancement of the technology,the development of systems and components and their exploitation over the last 60 years.Colin N.Danson Malcolm White John R.M.Barr Thomas Bett Peter Blyth David Bowley Ceri Brenner Robert J.Collins Neal Croxford A.E.Bucker Dangor Laurence Devereux Peter E.Dyer Anthony Dymoke-Bradshaw Christopher B.Edwards Paul Ewart Allister I.Ferguson John M.Girkin Denis R.Hall David C.Hanna Wayne Harris David I.Hillier Christopher J.Hooker Simon M.Hooker Nicholas Hopps Janet Hull David Hunt Dino A.Jaroszynski Mark Kempenaars Helmut Kessler Sir Peter L.Knight Steve Knight Adrian Knowles Ciaran L.S.Lewis Ken S.Lipton Abby Littlechild John Littlechild Peter Maggs Graeme P.A.Malcolm OBE Stuart P.D.Mangles William Martin Paul McKenna Richard O.Moore Clive Morrison Zulfikar Najmudin David Neely Geoff H.C.New Michael J.Norman Ted Paine Anthony W.Parker Rory R.Penman Geoff J.Pert Chris Pietraszewski Andrew Randewich Nadeem H.Rizvi Nigel Seddon MBE Zheng-Ming Sheng David Slater Roland A.Smith Christopher Spindloe Roy Taylor Gary Thomas John W.G.Tisch Justin S.Wark Colin Webb S.Mark Wiggins Dave Willford Trevor Winstone 2021High Power Laser Science and Engineering2021,9,2:5
5大型哺乳动物的趋势监测:青海野牛沟和甘肃阿克塞国际狩猎场的案例(英文)显示文摘大型野生动物种群数量估算的理想条件是使用数学模型以及严格的实验设计来选择样本。可是,野外条件状况往往违背数学模型假设前提,不可能随机地选择样本。于是,计算的结果不但不可靠,而且很可能没有意义。就野生动物管理来说,不需要获得一个准确的种群数量,只需一个长期的数量趋势,就足以指导相关管理工作。在中国大型哺乳动物长期监测还没有纳入常规。本文报道了位于青海省野牛沟和甘肃省阿克塞县两个野生有蹄类动物种群数量的长期趋势监测项目。我们这些年里一直用相同的方法持续监测,并明确了监测数值结果包含有不确定性。尽管存在不确定性,仍可以发现监测地点野生有蹄类动物种群变化趋势,这些结果可以帮助野生动物管理者据此变化及时作出相应管理计划。Richard B.

13Ten questions concerning future buildings beyond zero energy and carbon neutrality显示文摘Architects and planners have been at the forefront of envisioning a future built environment for millennia. How ever,fragmental view s that emphasize one facet of the built environment,such as energy,environment,or groundbreaking technologies,often do not achieve expected outcomes. Buildings are responsible for approximately one-third of w orldw ide carbon emissions and account for about 40% of primary energy consumption in the U. S. In addition to achieving the very ambitious goal of reducing building-associated greenhouse gas emissions by75% by 2050,buildings must improve their functionality and performance to meet current and future human,societal,and environmental needs in a changing w orld. In this article,w e introduce a new framew ork to guide potential evolution of the building stock in the next century,based on greenhouse gas emissions as the common thread to investigate the potential implications of new design paradigms,innovative operational strategies,and disruptive technologies. This framew ork emphasizes integration of multidisciplinary know ledge,scalability for mainstream buildings,and proactive approaches considering constraints and unknow ns.The framew ork integrates the interrelated aspects of the built environment through a series of quantitative metrics that aim to improve environmental outcomes w hile optimizing building performance to achieve healthy,adaptive,and productive buildings.Na Wang Patrick E.

17High-performance solutions of geographically weighted regression in R显示文摘As an established spatial analytical tool,Geographically Weighted Regression(GWR)has been applied across a variety of disciplines.However,its usage can be challenging for large datasets,which are increasingly prevalent in today’s digital world.In this study,we propose two high-performance R solutions for GWR via Multi-core Parallel(MP)and Compute Unified Device Architecture(CUDA)techniques,respectively GWR-MP and GWR-CUDA.We compared GWR-MP and GWR-CUDA with three existing solutions available in Geographically Weighted Models(GWmodel),Multi-scale GWR(MGWR)and Fast GWR(FastGWR).Results showed that all five solutions perform differently across varying sample sizes,with no single solution a clear winner in terms of computational efficiency.Specifically,solutions given in GWmodel and MGWR provided acceptable computational costs for GWR studies with a relatively small sample size.For a large sample size,GWR-MP and FastGWR provided coherent solutions on a Personal Computer(PC)with a common multi-core configuration,GWR-MP provided more efficient computing capacity for each core or thread than FastGWR.For cases when the sample size was very large,and for these cases only,GWR-CUDA provided the most efficient solution,but should note its I/O cost with small samples.In summary,GWR-MP and GWR-CUDA provided complementary high-performance R solutions to existing ones,where for certain data-rich GWR studies,they should be preferred.Binbin Lu Yigong Hu Daisuke Murakami Chris Brunsdon Alexis Comber Martin Charlton Paul Harris 2022Geo-Spatial Information Science2022,25,4:1
