包装lua c function, 也是极简单的, 但考虑到性能, ponder的做法是复用了相关的Traits实现, 重新包装了第5节的Function实现, 这样可以得到更高性能的跨语言调用设施. 所以很多时候, 我们应该是在整个系统不同层面去衡量性价比, 像上述代码实现不那么繁复, 又能够得到更好的性能的实现, 我们肯定会更多考虑. 通
Please note that for all traits, a TRAITS_FUNCTION_C concept (declared in "TypeTraits.h") will kick in for illegal values of "F" in C++20 or later ("F" is declared a TRAITS_FUNCTION_C in all templates below), or a "static_assert" in C++17 otherwise (again, earlier versions aren...

Here, we conducted an EWAS of kidney function traits to identify additional CpGs related to gene regulatory mechanisms of potential importance to CKD. We extended the former EWAS for eGFR and CKD by substantially increasing the sample size to 33,605 individuals. Moreover, we included UACR and mo...
