2Laser-direct-drive program: Promise, challenge, and path forward显示文摘Along with laser-indirect(X-ray)-drive and magnetic-drive target concepts,laser direct drive is a viable approach to achieving ignition and gain with inertial confinement fusion.In the United States,a national program has been established to demonstrate and understand the physics of laser direct drive.The program utilizes the Omega Laser Facility to conduct implosion and coupling physics at the nominally 30-kJ scale and lasereplasma interaction and coupling physics at the MJ scale at the National Ignition Facility.This article will discuss the motivation and challenges for laser direct drive and the broad-based program presently underway in the United States.E.M.Campbell V.N.Goncharov T.C.Sangster S.P.Regan P.B.Radha R.Betti J.F.Myatt D.H.Froula M.J.Rosenberg I.V.Igumenshchev W.Seka A.A.Solodov A.V.Maximov J.A.Marozas T.J.B.Collins D.Turnbull F.J.Marshall A.Shvydky J.P.Knauer R.L.McCrory A.B.Sefkow M.Hohenberger P.A.Michel T.Chapman L.Masse C.Goyon S.Ross J.W.Bates M.

3致命性与非致命性的扼颈是否存在颈部磁共振成像诊断标准?显示文摘本研究的主要目的是在扼颈后幸存者的放射学检查中明确可危及生命的客观征象.并通过将颈部横断层面分为3个区(前区、中区、后区)建立放射学评分系统来区分致命性与非致命性扼颈。法医病理学家通过评估事发经过与临床检查将56个扼颈后的幸存者情况分为致命性扼颈与非致命性扼颈,由2名放射学家盲法评价其颈部MRI表现。A.Christe H.Thoeny S.Ross D.Spendlove D.Tshering S.Bolliger 白荣杰 2009国际医学放射学杂志2009,32,5:2

7Thinking about U.S.-China Relations显示文摘Observers have long expected that the rise of China would challenge U.S.-China cooperation and regional stability.The typical assertion is that'power transitions'cause war.This is an overly-simplistic casual statement.The cause of war cannot be reduced to a single mechanical variable.But equally important,the rise of Chinese capabilities and theRobert S.Ross 2014Peace2014,,2:0
8“虚拟骨骼”的性别和年龄估测的可行性研究显示文摘本文介绍了多层CT(MDCT)估测死者骨龄和性别的可行性研究。为获得虚拟骨骼。用特殊方案对22例已知死亡年龄的死者进行多层CT扫描,包括头颅、肩胛骨(包括肱骨上段)、耻骨联合和股骨上段的高分辨率成像。骨与软组织进行了二维和三维的重建。3名具不同专业经验的人类学家对所测得的数据进行了分析。S.Grabherr C.Cooper S.Ulrich-Bochsler T.Uldin S.Ross L.Oesterhelweg 刘靖 2009国际医学放射学杂志2009,32,2:0
9Exotic parrots breeding in urban tree cavities: nesting requirements, geographic distribution, and potential impacts on cavity nesting birds in southeast Florida显示文摘Background:Exotic parrots have established breeding populations in southeast Florida,including several species that nest in tree cavities.We aimed to determine the species identity,nest site requirements,relative nest abundance,geographic distribution,and interactions of parrots with native cavity-nesting bird species.Methods:We searched Miami-Dade County,Florida,and nearby areas for natural cavities and holes excavated by woodpeckers,recording attributes of potential nest trees.We inspected all cavities with an elevated video inspection system to determine occupancy by parrots or other birds.We mapped nearly 4000 citizen science observations of parrots in our study area corresponding to our study period,and used these to construct range maps,comparing them to our nesting observations.Results:Not all parrots reported or observed in our study area were actively breeding.Some parrots were observed at tree cavities,which previous studies have suggested is evidence of reproduction,but our inspections with an elevated video inspection system suggest they never initiated nesting attempts.Several parrot species did successfully nest in tree cavities,Red-masked Parakeets(Psittacara erythrogenys)and Orange-winged Parrots(Amazona amazonica)being the most common(n=7 and 6 nests,respectively).These two parrots had similar nesting requirements,but Orange-winged Parrots use nests with larger entrance holes,which they often enlarge.Geographic analysis of nests combined with citizen science data indicate that parrots are limited to developed areas.The most common parrots were less abundant cavity nesters than the native birds which persist in Miami’s urban areas,and far less abundant than the invasive European Starling(Sturnus vulgaris).Conclusions:Exotic parrots breeding elsewhere in the world have harmed native cavity-nesting birds through interference competition,but competitive interference in southeast Florida is minimized by the urban affinities of parrots in this region.The relative abundance and geographic distribution suggest that these parrots are unlikely to invade adjacent wilderness areas.Joshua M.Diamond Michael S.Ross 2019Avian Research2019,10,4:0
10TOOTH PULP STIMULATION AND RESPONSESIN PARAFASCICULAR NUCLEUS显示文摘Electrical stimulation of the tooth pulp in humans produces a painful sensation .It seems reasonable to assume that similar trigeminal dental pain might be elicited by tooth pulp stimulation in cats.Manyauthors have demonstratedthat trigeminal nucleus caudalis (NV Caud) neurons respond to such pulp stimulation, and it is apparent, therefore, that these NV Caud neurons are in some way involved in dental pain.We report here that the parafascicular nucleus (Pf) of the thalamus may also be involved in dental pain, as it is involved in noxious stimuli arising from sensory nerves in other body parts.GILBERT S.ROSS 何淑舫 陈国光 张香桐 1984Chinese Science Bulletin1984,29,8:0
11丙型肝炎的自然史及传播显示文摘丙型肝炎病毒(HC)是肠道外非甲非乙肝炎的主要病原,也是引起输血后肝炎的主要致病因子,1989年由Choo首次发现。HCV具高度异质性,Simmonds据此将其分为不同的型及亚型,目前已确定了6种基因型及100多种亚型。HCV基因组为(+)ssRNA,全长约有9500个核苷酸,基因组结构与黄病毒及瘟病毒属病毒相似。HCV只有一个开放阅读框,包括3个结构蛋白:核心蛋白(C)及胞膜糖蛋白E1、E2。M.Roggendorf H.Meisel S.Ross S.Viazov 杨燕 2000德国医学2000,17,6:0
