| 1 | 多晶La_(0.49)Sr_(0.51)(Mn_(1-x)Nb_x)O_3的电输运特性研究显示文摘测量了B位掺杂的钙钛矿结构锰氧化物La0 49Sr0 51(Mn1-xNbx)O3(x=0,0 05,0 15和0 25)的电阻率和磁化强度的温度特性.实验结果表明,当Nb5+部分替代B位的Mn4+离子时,电阻率-温度特性由原来单一的半导体型转变成了高温时的半导体(绝缘体)型和低温时的类金属型.随Nb掺杂量增大,电阻率迅速升高3~5个数量级,半导体(绝缘体)-类金属转变温度降低.在掺杂Nb的样品中,只观察到顺磁-铁磁转变,而未观察到铁磁-反铁磁转变.上述实验结果的一种可能解释是掺杂改变了磁有序时电子自旋的排列和空间取向,从而改变载流子被自旋热涨落的散射作用和载流子转移的随机性. | 柳文军 舒启清 马晓翠 杜建设 李逢明 Troyanchuk I.O | 2004 | 深圳大学学报(理工版)2004，21，4： | 3 |

| 6 | Versus—A tool for evaluating visualizations and image quality using a 2AFC methodology显示文摘Novel visualization methods and strategies are necessary to cope with the deluge of datasets present in any scientific field to make discoveries and find answers to previously unanswered questions.These methods and strategies should not only present scientific findings as images in a concise way but also need to be effective and expressive,which often remain untested.Here,we present Versus,a tool to enable easy image quality assessment and image ranking,utilizing a two-alternative forced choice methodology(2AFC)and an efficient ranking algorithm based on a binary search.The tool provides a systematic way of setting up evaluation experiments via the web without the necessity to install any additional software or require any programming skills.Furthermore,Versus can easily interface with crowdsourcing platforms,such as Amazon’s Mechanical Turk,or can be used as a stand-alone system to carry out evaluations with experts.We demonstrate the use of Versus by means of an image evaluation study,aiming to determine if hue,saturation,brightness,and texture are good indicators of uncertainty in three-dimensional protein structures.Drawing from the power of crowdsourcing,we argue that there is demand and also great potential for this tool to become a standard for simple and fast image evaluations,with the aim to test the effectiveness and expressiveness of scientific visualizations. | Jenny Vuong Sandeep Kaur Julian Heinrich Bosco K.Ho Christopher J.Hammang Benedetta F.Baldi Seán I.O’Donoghue | 2018 | Visual Informatics2018，2，4： | 0 |
