The discovery of new drug and vaccine leads, the implementation of effective control measures in light of a changing world and an understanding of the mechanisms underlying human-parasite and vector-parasite interactions are all required to get a step closer to the ultimate goal of eradicating this disease. In all of these areas, the past year has produced some very interesting new insights that Nature are proud to present in this focus.

2009 US NEWS & World Report世界最好大学排名
wangyk 2009-11-8 20:08
王应宽 编译/转载 2009-11-08 UTC-6 CST UMN, St Paul 2009 US NEWS World Report 世界最好大学排名 博主按: 根据美国新闻与世界报道的网站( http://www.usnews.com ) 2009 年 10 月 20 日 发布其第二期的世界最好大学前 200 名排行榜( World's Best Universities: Top 200 )。此排名是基于时代高等教育与 QS Quacquarelli Symonds 联合问卷调查统计结果。其中美国大学占 54 席,占 27%, 英国位居次席,有 29 所大学进入前 200 名排行榜,占 14.5% 。中国大陆共有清华大学(第 49 名)、北京大学(第 52 名)、复旦大学(第 103 名)、上海交通大学(第 153 名)、中国科技大学(第 154 名)、南京大学(第 168 名)进入前 200 名排行榜。香港虽弹丸之地,但其多所大学进入排行榜,且排名位居前列:香港大学(第 24 名)、香港科技大学(第 35 名)、香港中文大学(第 46 名)、香港理工大学(第 195 名)。 此排名主要依据对不同主题加权统计评分,根据统计评分和加权分排名,主要包括以下六个指标: Academic Peer Review (40%), Citations per Faculty Member (20%), Student-to-Faculty Ratio (20%), Employer Review Survey (10%), International Students(5%), International Faculty Factors (5%) 。当然,此统计分析肯定存在一些误差,导致有些大学的排名波动很大,甚至时而入榜,时而落榜。例如,在上一次的排名中,列第 30 名的美国明尼苏达大学 University of Minnesota Twin Cities (本人目前所在的大学),在最新的排名中退居第 105 位;在上一榜中位于第 61 名的荷兰瓦赫宁根大学 Wageningen University ,在最新的排名中退居第 155 位;;在上一榜中位于第 77 名的美国德克萨斯 AM 大学 (Texas AM University) 在最新的排名中退居第 179 位。在上一榜中位居前列的大学,如美国加州大学旧金山分校 University of California at San Francisco( 第 9 名 ) ,美国科罗拉多大学 Boulder 分校 University of Colorado at Boulder( 第 51 名 ) ,美国密歇根州立大学 Michigan State University ( 第 62 名 ) ,在最新的前 200 位排名中竟然落榜!关于评估与统计结果是否科学合理,仁者见仁。关于此类排名,除了 US News World Report ,还有其它的很多。他姑妄排之,我姑妄转之,你姑妄听之。因此,希望读者和有关机构能正确对待此排名,不可不信,也不可全信,仅供参考而已。 1. 美国哈佛大学 Harvard University 2. 英国剑桥大学 University of

一周科技新闻简评——机器时代
songshuhui 2008-9-3 15:59
wilddonkey 发表于2008-04-21 星期一 18:35 分类: 其他 | | NASA 的工程师们正在对一种巨大的机器人进行测试,这种机器人的 使命是在荒无人烟的月球上充当宇航员的坐骑。这些大家伙宽 7.5 米,有六条 6 米多长的腿,绰号运动员,最快时速 10 公里。 运动员行动起来很稳重,像一只海龟,这有些辜负了它们的绰号。但稳重是必需的,因为背上是宇航员的住所。运动员每条腿都装上了轮子,可以行驶,经过有坡度的地方,各条腿的长度会自动进行调整,以确保住所里的宇航员坐的安稳。遇到大的沟坎,或是轮子陷进土里,运动 员会把轮子变成脚,六只脚轮流抬起、放下,小心翼翼走出困境。 有了这样一个坐骑,宇航员们就不必在固定的基地里日复一日的例行公事,而是有机会过上一种自由、浪漫的游牧生活。在荒凉的月球上四处游荡,在感兴趣的地方安营扎寨,勘探研究一番后,拔寨启程,开始新的旅途。 从月球到地球,人类越来越依赖于机器,各式各样的困难都试图通过 机器来解决。比如父母们在孩子长到一定程度,确切地说是牙齿已长齐并且能够独立使用牙刷的时候,会面临一个难题,那就是如何说服他们去刷牙。孩子们不喜欢刷牙,即便你成功地引发了他们的刷牙愿望,他们也会因为技术问题刷的不尽如人意,比如 5 岁的孩子通常只能清洁到 1/4 的牙齿。 为了解决这一难题,台湾大学的一个研究小组把这项枯燥乏味的琐事改造成了一场游戏。这场游戏的参与者包括接在普通牙刷 尾部的一个长方形小盒子,盒子的四个面嵌有以不同模式排列的三个发光二极管;一个安在盥洗台上方,通过发光二极管实时跟踪牙刷移动的摄像机;一个放在盥洗台上的计算机,接收摄像机发来的牙刷实时移动数据,据此精确计算出哪颗牙正在被刷到,并在屏幕上显示出一颗虚拟的牙齿从脏兮兮的五颜六色变为了光亮白净;最后,还需要一个觉得看到屏幕上的虚拟牙齿随着自己的动作一个个变干净非常有趣,乐在其中的孩子。 这场刷牙游戏或许还能吸引更大一点的孩子,甚至成年人,不过那需要屏幕上显示出 的场景更好玩一些。 家中添置了新机器,那些比电冰箱、洗衣机更高级、更智能的机器会给我们的 生活 带 来什 么新的改变?一个盘子大小的机器人正 在家中各个阴暗角落里 辛勤工作,确切地说它是一个自动吸尘器,商品名 Roo mba , iRobot 公司生产。但它的主人 不会认同这种说法,主人给它套上了外套,另起了名 字,赋予了性别,它成为了家中的一员。人们开始对身边的机器产生感情。 在伊拉克的美国士兵承认当他们的机器人被炸弹、地雷摧毁时,他们感到非常悲伤。 2020 年后,常驻月 球的宇航员们也会对自己的坐骑生出情感。未来,人与机器将演绎出更为复杂动人的情感纠葛。 标签: machine time , news
