IF: 16+ Studying the correlation between immunosuppressive tumor microenvironment and liver metastasis of pancreatic cancer based on scRNA-seq
The tutorials of Huanfeng Gene not only teach you how to use it, but also regularly analyze some related articles. Learning the tutorials is only the basis, but integrating the analysis results into the articles is the purpose. I think our tutorials are pretty good, and you can follow our If you get good results […]
B – Influence on Social media, factor decomposition, thinking, unordered_map
Influence on Social media – Problems – CodeChef Problem Recently social media has been flooded by fb posts, tweets, news articles about only thing – demonetization. A great debate is ongoing over it. Most of the people discussing in social media platform usually tend to take sides, i.e. either they support the move, or they […]

Telecom ctyunos install docker-ce
This installation is the first time to use ctyunos, and it also needs to install docker in the intranet environment. This self-developed system currently lacks documentation. I have been struggling for a few days. I hope it can provide some ideas for colleagues who encounter similar problems. There is no guarantee. This record can solve […]
Encapsulation of unordered_map and unordered_set
In STL, the search of unordered_map and unordered_set is at the ceiling level. Their underlying logic is very simple, which is hash poke. The logic of hash poke is very simple, just different linked lists and arrays (in my opinion). But don’t insist on implementing unordered_map and unordered_set. It’s very simple. Just like cooking, each […]

C++ – unordered series of associative containers and hashes
1. unordered series associative containers 2. Hash principle 3. Unordered_map simulation implementation 1. unordered series associative containers unordered_map is an associative container that stores key-value pairs. Their types can be different. Unlike map, unordered_map does not perform a specific sorting of key values. Its bottom layer uses hash, and the hash values are the same. […]
