查询词典 differentiation symbol

During sexual differentiation, mitochondria and smooth endoplasmic reticulum in cells of testis also increase in quantity, but it is less than that in ovary, they disintegrate after sexual differentiation. The big grana always exsist in course of sexual differentiation, but small grana don\'t appear.

分化时精巢细胞的超微结构显示线粒体和内质网数量也有增加，但不如分化中卵巢细胞的数量多，分化后线粒体和内质网解体，在整个分化过程中大颗粒一直存在，无小颗粒出现。

Meanwhile,HDAC1 acetylation level is significantly increased.The overexpression of HDAC1 can promote erythroid cell proliferation and inhibits induced differentiation,the knockdown of HDAC1 or 2 inhibits erythroid cell proliferation and promotes induced differentiation.We also found that HDAC1 affects GATA1 mediated transcription activity.Thus our data revealed that HDAC1 may negatively regulate GATA1 mediated transcription and suggest that the dynamic regulation of GATA1 associated NuRD/MeCP1/HDAC1/HDAC2 complex may determine the onset of erythroid differentiation programs.Moreover,this study will eventually help to design new therapeutic approaches in treatment of leukemia.

研究发现在被诱导分化的小鼠红细胞白血病细胞中与GATA1相结合的HDAC1被乙酰化并失去活性，在血细胞中过表达HDAC1能够促进血细胞的增殖并抑制分化，反之在血细胞中敲除HDAC1或HDAC2能抑制血红细胞的增殖并促进分化，而且HDAC1能够负调控GATA1的转录活性，GATA1与NuRD/MeCP1复合体之间的动态调控，决定血红细胞分化的发生和发展，并为探索白血病的致病机理奠定了理论基础。

Background: The stem cell is a kind of cell which can keep alive for a long term and has a few of differentiation potencies. While, the progenitor cell is a kind of cell keeping one or double ways of differentiation and the capability of its differentiation, self-renew and self-maintenance is confined.

一、研究背景干细胞是一类不分化而长期生存且保持多种分化潜能的细胞群，而祖细胞是一类分化能力、自我更新、自我维持能力受限制，只有单向或双向分化潜能且生存时间相对较短的细胞群。

A new symbol-constrained joint source-channel decoding algorithm for VLCs is presented.By constructing double-tree VLCs sources,the propagation-error problem is evidently alleviated.Meanwhile,by applying symbol-constrained method to MAP algorithm,not only the a priori probability of VLCs sources is efficiently utilized,but also the Symbol Error Rate is reduced enormously.

提出了一种新的针对不等长编码信源的符号约束MAP联合译码算法，利用VLCs双树信源的构造方法，有效地抑制了VLCs的错误扩散；同时，通过将"符号约束"的思想应用于最大后验概率译码算法，不仅充分利用了信源先验信息，而且极大地降低了误符号率。

Taking the symbol as the product information carriers and basic elements, the symbol modeling realizes the information description with formalization, abstraction and integration, expresses the product design process with symbol model evolution, and offers the new theory and method for product development.

符号建模以设计对象符号作为产品信息的载体和建模基本元素，实现了信息的形式化、抽象化和集成化描述，通过符号模型的演变表达了产品的设计过程，为产品开发提供了一种新的理论和方法。

Jeff: Duckbill indicated the city of Sydney , which was the symbol of water; Millie was the symbol of land; and kookaburra was the symbol of the air.

杰夫：鸭嘴兽，悉德也表示悉尼，象征水；针，米利象征土地；笑翠鸟，奥利象征空气。注意，注意力集中

Analysis for testability is widely used in DFT and test pattern generation, but most testability analysis algorithms have the shortcoming of either inaccuracy or being too complicated. A new method to calculate the signal probabilities of the nodes in IC is pre-sented in Chapter 7 of this dissertation. The signal probabilities by our method is more exact than by the previous ones. A symbol of the signal probability at the fan-out node is created and is propagated to the RFON (Reconvergent Fan-out Nodes). At the RFON, the expression containing the symbol is simplified using the rule which corresponds to the law of identity in Boolean algebra. After the expression is simplified, the symbol is substituted with its numeric value. Theoretical analysis shows that this method is concise and has a low computing complexity.

可测试性分析在可测试性设计和测试生成中都有着广泛的应用，然而大部分的可测性分析方法都存在不精确或者过于复杂的毛病，在第七章中作者提出了一种新的计算IC电路节点的信号概率值的符号算法，该算法得出的信号概率值比用以往的算法法得出的要更准确，也更简洁，针对电路中的扇出节点重汇聚现象，我们在每一个扇出节点定义了一个信号概率的符号，在以后的计算中一直使用该符号参与计算，直到该符号传播至重汇聚处，利用一定的规则把含符号的表达式化简，再将符号的真实值代入，在计算符号概率的过程中定义了一个和布尔代数中的同一律相对应的运算规则，通过该运算规则，使得信号概率的结果更加准确，符号算法具有简洁方便，计算复杂度小的特点 4。
