科技英语教案大学英语读写四教案③宏观量子隧道效应宏观量子隧道效应是指纳米粒子的一些宏观量（如磁化强度）具有贯穿势垒的能力。
这一效应限定了磁盘、磁带等存储介质的存储时间极限，因为它不但是未来微电子器件的发展基础，也是其进一步微型化的极限。
例如，在制造半导体集成电路时，当电路的尺寸接近电子波长时，电子将通过隧道效应而穿透绝缘层，使器件无法正常工作。
因此，宏观量子隧道效应已成为微电子学、光电子学中的重要理论。
“Targeting Drug Delivery System”靶向给药系统或称靶向制剂，诞生于20世纪70年代，是指这种制剂能将药品运送到靶器药物通过局部或全身血液循环而浓集定位于靶组织、靶器官、靶细胞的给药系统官或靶细胞，而正常部位几乎不受药物的影响。
①Targeted drug delivery, sometimes called smart drug delivery,[1] is a method of delivering medication to a patient in a manner that increases the concentration of the medication in some parts of the body relative to others.②The goal of a targeted drug delivery system is to prolong, localize, target and have a protected drug interaction with the diseased tissue.③The conventional drug delivery system is the absorption of the drug across a biological membrane, whereas the targeted release system is when the drug is released in a dosage form.④The advantages to the targeted release system is the reduction in the frequency of the dosages taken by the patient, having a more uniform effect of the drug, reduction of drug side effects, and reduced fluctuation in circulating drug levels. The disadvantage of the system is high cost which makes productivity more difficult and the reduced ability to adjust the dosages.⑤There are two kinds of targeted drug delivery, active targeted drug delivery, such as some antibody medications; and passive targeted drug delivery, such as the enhanced permeability and retention effect (EPR-effect).⑥Delivery vehiclesThere are different types of drug delivery vehicles, such as, polymeric micelles, liposomes, lipoprotein-based drug carriers, nano-particle drug carriers, dendrimers etc. An ideal drug delivery vehicle must be non-toxic, biocompatible, non-immunogenic, biodegradable and avoid recognition by the host's defense mechanisms.Liposomes are composite structures made of phospholipids and may contain small amounts of other molecules. Though liposomes can vary in size from low micrometer range to tens of micrometers, unilamellar liposomes, as pictured here, are typically in the lower size range with various targeting ligands attached to their surface allowing for their surface-attachment and accumulation in pathological areas for treatment of disease. The most common vehicle currently used for targeted drug delivery is the liposome. Liposomes are non-toxic, non-hemolytic and non-immunogenic even upon repeated injections; they are biocompatible and biodegradable4.Text comprehension ( 35 minutes)Ask the students to read the text and discuss the following questions.1)What did NCI announce?Tips: (Para.1) nanotech solutions to cancer2)What is nanotech?3)Why does it hold promise for cancer detection and therapy?Tips: (Para.2) Size and function.Targeted Drug Delivery System4)What are the delivery vehicles for cancer detection?Tips: two kinds of nanoparticlesnanocrystals of iron oxide (Para.3-5)quantum dot-probes (Para.6-8)5)Please find out the related researchers and the discoveries of their research.Tips:Nanocrystals of iron oxide:Researcher: Jinwoo Cheon, a chemist at Yonsei Universary in Seoul, South Koreareported in the Sept. 7 Journal of the American Chemical SocietyHis report: It can make MRI pick out smaller tumors (Para 3-4); An experiment.

Symmetric division gives rise to two identical daughter cells both endowed with stem cell properties. Asymmetric division, on the other hand, produces only one stem cell and a progenitor cell with limited self-renewal potential. Progenitors can go through several rounds of cell division before terminally differentiating into a mature cell.“The value of hES cells in recovering spinal cord injuries”科技英语教案科技英语教案科技英语教案科技英语教案科技英语教案。

Unit1
搏弈的实质是搏弈者采取策略之间的相互依赖性。
这种策略性的相互依赖表现为两个不同的类别：连续策略之间的相互作用以及联立策略之间的相互作用。
当我们把博弈的结果表述为一种均衡的时候，并不是基于以下的假设：即博弈的每个参与者的个人最佳策略将会带来共同的最优化结果。
在一些冲突中，任何规律性的行为都会被对手发觉并利用。
因而，通过采取混合性策略来迷惑对手就显的非常重要。
我们可以从体育运动中找到一些典型的例子，比如足球运动中的特定情况下选择跑位还是传球，网球比赛中选择击打近网球还是底线球。
边缘化策略就是故意使局势变的无法控制的策略，正是由于局势的无法收拾可能令其他对手难以接受，从而迫使对手作出妥协。
当博弈的一方掌握其他各方不了解的信息时，他会急于隐瞒这一信息(例如纸牌游戏中抽到的牌)，其他情况下他也可能想把信息令人信服的公布出来。
这两种情况下，一个基本的原则就是行胜于言。

正常情况下，如果一个健康的细胞发生了许多突变而不能继续正常生长，p53基因就会诱发细胞自杀。
然而，假如这个基因停止作用，细胞就会持续生长，最终可能变为恶性肿瘤细胞。

胚胎干细胞的极强的适应性以及生长能力使它们能够产生大量的治疗细胞去治疗像糖尿病及脊髓损伤一类的疾病。
该细胞可形成少突神经胶质细胞，其功能之一是产生保护性髓磷脂鞘使神经元能够沿着神经轴突
传递信号。
也许对人体胚胎干细胞疗法的最大担心在于它可能诱发肿瘤形成。
已明确的是在免疫受损小鼠皮下注射未分化的胚胎细胞时可形成非组织性肿瘤，即畸胎瘤。
比如，培养的细胞通常在胎牛血清中存活，大多数人体胚胎干细胞生长在滋养层细胞的鼠细胞层上，以提供关键蛋白质防止胚胎细胞分化。
最后，一些研究者担心在培养中胚胎细胞可能会获得有害的新突变。
这种突变事先是难以检测到的。

通过使用PCMM规，有线运营商可以对时延敏感或富有特色的应用给予优先权或预留带宽，从而加深用户对于宽带业务的感受。
ＰＣＭＭ体系结构包括六个主要组成部分：ＩＰ端点（ＰＣ机、游戏控制器或ＳＩＰ话机）、电缆调制解调器、电缆调制解调器终端系统（ＣＭＴＳ）、记录保持服务器、策略服务器和应用管理器。
当用户从蜂窝网移至ＷｉＦｉ服务区时，无缝蜂窝漫游系统将告知移动运营商，使信号从蜂窝天线塔转移至ＷｉＦｉ接入点，启动手机的宽带功能，同时保持话音通信。
进入无线网络竞争的新技术是网状网，它要把“热点”的概念变为理想的“城点”概念。
有源以太网利用了以太网和ＩＰ这两种标准技术无所不在的特点，把相关网络设备安装在用户网络边缘，而不是在中心局或局端。

变得越来越智能、小型、快速，并且能够让用户高速地连接到因特网，一个显而易见的问题就出现了：移动手持设备将成为下一代的计算机吗？
还有一些正在开发中的智能，他们将带有摄象机、GPS天线以及本地Wi-Fi（一种常在办公室、机场和本地咖啡馆能找到的超高速无限网络）热点的入口。
有了这项功能，手机很快就能提供诸如精确的行车向导、走过店铺时店铺的打折信息，以及开展约会等服务。
手机不太可能沿着最快的道路飞驶向自己光明的未来。
这个行业里的创新充满了曲折和失误，这常常是由于没有任何一家单独的公司能完全控制这一产品。
然而，手机创新者也正着手解决这个棘手的问题。
科学家已经在语音识别系统方面进行了数十年的研究，而且此项研究仍在继续。
最近已将这项技术引入了PDA中。
