Carcinoma in situ is categorized stage 0; often tumors localized to the organ of origin are staged as I or II depending on the extent, locally extensive spread, to regional nodes are staged as III, and those with distant metastasis staged as stage IV. However, in some tumor types stage groups do not conform to this simplified schema.

PL/0 程序设计语言是一个较简单的语言，它以赋值语句为基础，构造概念有 顺序、条件和重复（循环）三种。 PL/0 有子程序概念，包括过程定义（可以嵌 套）与调用且有局部变量说明。 PL/0 中唯一的数据类型是整型，可以用来说明 该类型的常量和变量。 当然 PL/0 也具有通常的算术运算和关系运算。 PL/0 是一个小巧的高级语言。 虽然它只有整数类型，但它是相当完全的可嵌套的分程序（block）的程序结构，分程序中可以有常量定义、变量声明和无参过程声明，过程体又 …

2013年2月11日 · In the seventh edition of TNM, there is now an expanded definition of complete resection (R0), which recommends that at least six lymph nodes/nodal stations be removed/sampled and confirmed on histology to be free of disease to confer pN0 status.

This study emphasizes that the presence of VPI is related with poor prognosis independent of lymph node positivity, histologic subtypes, and tumor size. As the study shows, PL0 and PL1 have similar survival rates and these two groups may be considered as VPI (-) patients whereas PL2 disease affects …

PL/0 is a programming language, intended as an educational programming language, that is similar to but much simpler than Pascal, a general-purpose programming language. It serves as an example of how to construct a compiler. It was originally introduced in the book, Algorithms + Data Structures = Programs, by Niklaus Wirth in 1976.

Left recurrent laryngeal nerve paralysis is classified as T4 when directly invaded by the primary tumor but as N2 when invaded by nodal disease. Similarly, infiltration of the superior vena cava, trachea, or esophagus by the primary tumor is defined as T4 but as N2 or N3 when due to infiltration emanating from lymph nodes.

R0 means that the re-sected area (ie. the area around the tumour that was removed) was clear. Pleaer do not try and google - the information is out of date and downright scary in places .

T0 means there is no sign of cancer. Tis means an area of cancer cells contained within the inner lining of the lungs. T1 means the cancer is contained within the lung. T1mi is a staging …

本项目主要是对PL/0编译程序的研究与改进，并通过本次的任务帮助读者对编译程序的实现建立起一个整体概念。 所谓PL/0语言即是Pascal语言的一个子集，它的编译程序是一个编译解释执 …

r0 ~ r12是通用寄存器，就是计算的时候会用到，没有特殊的含义. CPSR是当前程序的状态寄存器，里面存储着很多信息，包括当前的指令模式（是thumb还是arm），以及当前的处理器模式（user/fiq/…） SPSR全程是 saved program status reg，它的目的就是作为CPSR的一份备份，那备份这个有什么用呢，文档里说了就是为了一旦异常发生，能够用到这个备份的值. 同一指令附带不同的后缀，变成不同的指令，常用后缀包括： 文章浏览阅读9.9k次，点赞6次，收藏50次。
