A tumor marker is a biomarker found in blood, urine or body tissues that can be elevated by the presence of one or more types of cancer. There are many different tumor markers, each indicative of a particular disease process, and they are used in oncology to help detect the presence of cancer. An elevated level of a tumor marker can indicate cancer; however, there can also be other causes of elevated level of a tumor marker. Tumor markers can be produced directly by the tumor or by non-tumor cells as a response to the presence of a tumor.

时装周设计师Rui Zhou呈现Presentation
自己关注Rui Zhou好久了，一直特别喜欢这个品牌。
一开始看到的时候觉得很难驾驭，到后面看到身边很多朋友把这个元素加入到自己的穿搭里。觉得Rui Zhou的设计特别有记忆点，也很特别。所以昨天朋友问了我，就欣然答应来欣赏Rui Zhou的Presentation了～
整个Presentation呈现都很概念化、情景化。首先是地理位置的选择，在上海静安区的一栋老房子里。室内的整体风格属于破旧的90年代工业风。我觉得最特别的是，Rui zhou把自己的设计和整个的建筑风格结合在了一起。让建筑也穿上Rui Zhou的设计元素。
其次是Presentation，开场几位模特先是在一个窗口进入状态，再是出来到场中走动；然后在每个场景中都会有小故事化的呼应。
整场看下来很喜欢，也很喜欢图一的女孩！♥️♥️♥️

【Application of Stochastic Optimization to Optimal Preventive Maintenance Problem】
#论文##维修# #成本# #效果# #随机优化#
The maintenance objective is as a rule to increase the lifetime of maintained device and to reduce the maintenance costs simultaneously. In the present paper, a rather general model of sequential maintenance actions, including their effects and costs, is sketched, and the problem of stochastic optimization of action times is formulated. Further, the method of numerical solution is proposed.
