文献编号:19Mar - 11 2019年04月23日三读,会其精髓: 相信这种方法的话,那么它的精髓是什么,如何整合出这个core gene set. 首先要考虑样本的选择,样本里是否存在明显的分层? 2019年04月01日再读:精读: 已经发现我的data没法在PCA里有明显的规律:应该可以直接从bulk RNA-seq里获取有价值的信息,那么single cell到底有什么优势呢?回答:单细胞的数据是必须的,它可以把core genes锚定到case-control pseudotime,…

Geometrical Progression n == 1的时候答案为区间长度, n == 2的时候每两个数字都可能成为答案, 我们只需要考虑 n == 3的情况, 我们可以枚举公差, 其分子分母都在sqrt(1e7)以内, 然后暴力枚举就好啦. #include<bits/stdc++.h> #define LL long long #define fi first #define se second #define mk make_pair #define PLL pair<LL,…
