Takayuki Tamura and his colleagues work at the Product Development Research Laboratory of Mercian Corporation in Kanagawa, Japan. They started their exploration of what was behind the strange aftertaste by asking seven experienced wine tasters to sample red wines and white wines while eating scallops. The panellists were instructed to rate the presence of any fishy aftertaste on a scale of zero to four, with zero indicating no such aftertaste and four indicating an extremely strong one. Over the course of four sessions, they were presented with a grand total of 38 red wines, 26 white ones, 2 sherries, a dessert wine, a port and a Madeira. The drinks were offered in random order, in coded glasses.
Takayuki Tamura和他的同事在位于日本Kanagawa的Mercian公司的产品研发实验室工作,通过询问7位边吃扇贝边品尝红酒和白酒的经验丰富的品酒师,他们开始探索隐藏在奇怪的回味背后的东西,他们被要求将任何鱼腥味的回味分成0到4几个等级,0表示没有这样的回味,4表示回味相当浓,经过四个连续的时间段的试验,他们品尝了38种红酒、26种白酒、2种雪利酒、1种甜酒、1种葡萄酒和1种Madeira白葡萄酒,酒装在带有编码的杯子里,按照随机顺序提供。

Glioma is still one of refractory disease in the neurosurgical field; the development of new primary and adjuvant treatment is vital. Recently, the gene therapy of glioma is developed rapidly and there are many methods about the gene therapy that include: suicide gene therapy, immunologic gene therapy, drug resistangce gene therapy, angiostatin gene therapy and so on. The sucide gene therapy is the most potential approach of antitumer, these nonmammalian genes encode enzyme that convert nontoxic prodrugs into highly toxic metablites. Cells transfected with suicide genes are targeted for specific negative selection, witch can be induced by administrtion of the corresponding produg. Among the enzyme/produg combinations, two of the best characterized system are herpes simplex virus thymidine kinase /ganciclovir and Escherichia coli cytosine deaminase /5-flourocytosine (5-FC). The formor can convert the antiviral nucleoside analogs acyclovir , ganciclovir to their nucleoside monophosphate derivatives, the monophosphate forms are subsequently phosphorylated by endogenus cellular kinases to triphosphates, these molecules are potent inhibitors of DNA synthesis.
近年来脑胶质瘤的基因治疗发展迅速,应运而生的方法有自杀基因、免疫基因、多药耐药基因以及抗血管生成基因等,其中自杀基因被认为是最有前景的基因治疗方法,它又称病毒介导的酶/药物前体疗法,是利用转基因技术将哺乳动物细胞中所不含有的自杀基因转入到哺乳动物肿瘤细胞中,该基因表达的产物可将无毒的药物前体转化为毒性药物,从而选择性杀伤该肿瘤细胞,常用的自杀基因有单纯疱疹病毒-胸苷激酶基因和大肠杆菌胞嘧啶脱氨酶基因,前者催化无毒性抗病毒核苷类似物如丙氧鸟苷、无环鸟苷等成为单磷酸核苷衍生物,然后在内源性细胞激酶作用下转化为具有明显毒性的三磷酸核苷,作为DNA合成链的终止剂和DNA合成酶的抑制剂,干扰细胞DNA的合成;后者编码的胞嘧啶脱氨酶可催化5-氟胞嘧啶(5-FC)脱氨成为5-氟尿嘧啶(5-FU),然后代谢为有毒性的5-氟尿嘧啶-5′三磷酸(5-FUTP)和5-氟-2′脱氧尿嘧啶-5′磷酸(5-FdUTP),5-FUTP通过与UTP竞争性结合而抑制mRNA和tRNA的合成,5-FdUTP则作用于胸苷合成酶,导致TMP衰竭而阻止DNA的合成,最终诱导肿瘤细胞凋亡。

摘要传统的测频仪器体积很大,耗能量大,主要靠手工操作,而最大的缺点是不可编程,其量程转换、数据测量、采样控制和处理等均不能通过程序指令来进行控制,无法作为一个微型智能子系统与某一大型自动控制或测试系统进行接口。针对这些缺点,本频率计再设计上作了根本的革新,其优点是:所用核心器件是先进的单片专用测频器件——单片频率计,集成度高,体积小,耗电省,功能强,实现了频率计的高度集成化和微型化;单片频率计只要加上晶振、量程选择、频率显示等很晌慰的器件即可构成一个DC至10MHz的微型基本测频电路;而最大的优点则是本频率计完全实现了单片频率计、频率采样与单片微机三者之间的硬件与软件接口,使得测频量程的选择、频率数据的测量、采样以及编码的边境转换和数据的转储均可能过单片微机的软件编程自动进行,从而实现了测频与采样工作的完全智能化,使得本系统既可独立构成一个微型智能测率仪器的核心电路,也可作为大型自动控制或测试系统中的一个智能子系统。关键词高度集成化,单片机,频率计,电路

One transmission cell to another while maintaining the DVB-H service.· For a number of reception scenarios; indoor, outdoor, pedestrian and inside amoving vehicle, the transmission system shall offer sufficient flexibility and scalability to allow the reception of DVB-H services at various speeds, whilstoptimizing transmitter coverage.· As services are expected to be delivered in environments that suffer high levels of man-made noise, the transmission system shall offer the means to mitigate their effects on the performance of the receiving terminal.· As DVB-H aims to provide a generic way to serve handheld terminals in various part of the world, the transmission system shall offer the flexibility to be used in various transmission bands and channel bandwidths.
因此DVB-H采用分时方式的资料传送形式,把原本通道频宽是由其它节目共同分配享有的,现在只可以让某一个节目使用全部的频宽所以让节目传送的位元率提高了,相对的减少传送的时间,但跟DVB-T一样在单位时间内所传送的资料是一样多的,由於DVB-H采用分时多工的方式传送资料所以接收器只在该节目传送的时间内接收该笔资料,而其它时间则不接收然后在等一个单位时间内,该节目的资料再传送时在接收,如此开关开关达到收到整部节目的资料,并大量的减少持续接收节目所消耗的功率,接下来由於DVB-H采用4K正交分频多工编码的方式,虽然涵盖的范围没有DVB-T大但对高速移动的时候接收信号时的效果会比较好。

This represents a fundamental mathematical limit on the best possible lossless data compression of any communication: considering a certain message as a series of realisations of a certain random variable (where the random variable can be "the next letter", or "the next word", or any other subdivision of text), the shortest number of bits necessary to transmit one message is the Shannon entropy of the corresponding random variable, multiplied by the number of realisations in the original text.
当然如果各个队夺冠的几率不等的话,那么熵则不会是5。因为如果从强队开始问问题,则不需要5个问题一般就可以得到答案。而根据哈夫曼编码的启发,我们表示这32个队,不需要平均长度为5的二进制位。从另外一个角度来看,熵作为信息量的大小也是表达能力的衡量,或者是不确定度的衡量和混乱程度的表现。为什么选择log来表示熵呢?如果X的表达能力为H,Y的表达能力为H,那么X+Y的表达能力应该是二者的乘积,所以H = H + H。
