| 1 | 中国晚中新世陆相哺乳动物群序列:陕西蓝田的新证据(英文)显示文摘自 2 0世纪 60年代 ,陕西蓝田地区就以连续的晚新生代地层及丰富的哺乳动物化石而成为研究中国晚新生代哺乳动物与地层划分对比的经典地区之一。李传夔等 ( 1 984)根据灞河组发现的哺乳动物化石建立了灞河期 ,并与欧洲的Vallesian期对比。邱占祥等( 1 990 ,1 995)认为化石证据不充分 ,而将其与保德期合并。近年来 ,黄土高原三趾马红粘土大量的年代学资料表明 ,红粘土沉积最早可能开始于约 8Ma前。因此 ,狭义的保德期可能只代表了晚中新世晚期 ,晚中新世哺乳动物分期的再划分问题又重新被提出。自 1 997年以来 ,我们课题组在蓝田地区共发现 52个化石地点 ,其中的 2 6个含有哺乳动物化石 ,大哺乳动物化石标本共计 1 666件。经过详细野外地层测量 ,绘制了综合地层剖面 ,并将主要含哺乳动物化石的地点对比标定到综合地层剖面上。经过对各门类化石的初步研究 ,以及对已有化石材料的初步修订 ,到目前为止 ,陕西蓝田灞河组共计发现哺乳动物化石 45种 ,蓝田组 2 0种。新的化石证据表明 ,灞河组发现的哺乳动物化石组合完全不同于典型意义上的保德三趾马动物群。大哺乳动物化石以灞河三趾马与贾氏三趾马为代表 ,牛科化石组合在种级甚至属级上有明显的区别。大量的陕西转角羚羊 ,小型的Protoryx。 | 张兆群 A.W.Gentry A.Kaakinen 刘丽萍 J.P.Lunkka 邱铸鼎 S.Sen R.Scott L.Werdelin 郑绍华 傅铭楷 | 2002 | 古脊椎动物学报2002,40,3: | 38 |
| 2 | 分析和选择教学策略及方法显示文摘一般的教学设计模式都少不了“依据教学内容和学生的需要制定教学策略”这一环节(Andrew& Goodson,1980,p.5),然而在各种教学设计模式中,教学策略的含义和目的却大相径庭。传统的教学设计模式常把教学策略等同于选择教学传递方式(如讲授、演示、计算机辅助教学等)和教学支持活动(如练习、辅导)(Tracey,Flynn,& Legere,1970)。如果把这些教学策略的概念与精细加工理论(Reigeluth& Stein,1983)所提出的“包容性排序,自我调整、综合、总结和激活认知策略”等教学策略作一比较,我们不难看出不同的教学设计人员对教学策略的定义并不一致,许多所谓的教学策略其实只是呈现方式而已。本文首先对交互式教学设计模式中的教学策略及其教学方法加以界定和区分,然后列举出一系列教学策略和教学方法,最后提出帮助设计人员优选教学方法的决策思路。 | David H.Jonassen R.Scott Grabinger N.Duncan C.Harris 褚献华 | 2004 | 远程教育杂志2004,22,3: | 12 |

| 17 | Cannabinoids and endocannabinoids as therapeutics for nervous system disorders:preclinical models and clinical studies显示文摘Cannabinoids are lipophilic substances derived from Cannabis sativa that can exert a variety of effects in the human body.They have been studied in cellular and animal models as well as in human clinical trials for their therapeutic benefits in several human diseases.Some of these include central nervous system(CNS)diseases and dysfunctions such as forms of epilepsy,multiple sclerosis,Parkinson’s disease,pain and neuropsychiatric disorders.In addition,the endogenously produced cannabinoid lipids,endocannabinoids,are critical for normal CNS function,and if controlled or modified,may represent an additional therapeutic avenue for CNS diseases.This review discusses in vitro cellular,ex vivo tissue and in vivo animal model studies on cannabinoids and their utility as therapeutics in multiple CNS pathologies.In addition,the review provides an overview on the use of cannabinoids in human clinical trials for a variety of CNS diseases.Cannabinoids and endocannabinoids hold promise for use as disease modifiers and therapeutic agents for the prevention or treatment of neurodegenerative diseases and neurological disorders. | R.Scott Duncan Sean M.Riordan Matthew C.Gernon Peter Koulen | 2024 | Neural Regeneration Research2024,19,4: | 0 |

| 19 | High-Resolution 3-D Radar Imaging through Nonuniform Fast Fourier Transform(NUFFT)显示文摘This paper applies a 3-D nonuniform fast Fourier transform(NUFFT)migration method to image both free-space and buried targets from data collected by a ultra-wideband ground penetrating radar(GPR)system.The method incorporates the NUFFT algorithm into 3-D phase shift migration to evaluate the inverse Fourier transform more accurately and more efficiently than the conventional migration methods.Previously,the nonuniform nature of the wavenumber space required linear interpolation before the regular fast Fourier transform(FFT)could be applied.However,linear interpolation usually degrades the quality of reconstructed images.The NUFFT method mitigates such errors by using high-order spatial-varying kernels.The NUFFT migration method is utilized to reconstruct GPR images collected in laboratory.A plywood sheet in free space and a buried plexiglas chamber are successfully reconstructed.The results in 3-D visualization demonstrate the outstanding performance of the method to retrieve the geometry of the objects.Several buried landmines are also scanned and reconstructed using this method.Since the images resolve the features of the objects well,they can be utilized to assist the landmine discrimination. | Jiayu Song Qing H.Liu Kangwook Kim Waymond R.Scott,Jr. | 2006 | Communications in Computational Physics2006,1,1: | 0 |
