Function minimization with fixed polarity based on K map(基于K图的函数RM展开式在固定极性下的最小化)
Zhejiang Daxue xuebao. Lixue ban, 2003 分析了K图的性质,发现在K图中过某格的所有聚合圈相应的各乘积项所含变量与该格对应的最小项均有相同的极性,在此基础上提出了得到基于K图函数RM展开式在固定极性下的最小化的图形方法.该方法可以从K图直接得到函数的最小化的RM展开式,从而省略了传统的把K图转变为bj图再求最小化的步骤.它具有直观、简单、易于掌握等特点.此外,文中还提出了该方法的改进算法.

Cancer Medicine, Volume 8, Issue 15, Page 6528-6537, November 2019., 2019 Active surveillance is an alternative management for patents with low‐risk papillary thyroid microcarcinoma (PTMC); however, there is an absence of specific molecular markers that predict its progression. In this study, genes related to EMT and thyroid cancer stem cell‐like properties are upregulated in early extensive lymphatic spread of PTMC ...

Conservation Biology, Volume 33, Issue 4, Page 769-776, August 2019., 2019 Abstract Some conservationists believe that free‐ranging cats pose an enormous risk to biodiversity and public health and therefore should be eliminated from the landscape by any means necessary. They further claim that those who question the science or ethics behind their arguments are science deniers (merchants of doubt) seeking to mislead the public.
