科学家发现橘猫的基因突变
#生物技术
许多哺乳动物都有橘色变种——如老虎、金毛犬、红毛猩猩和红发人类——但只有家猫的橘色特征与性别相关，且更多出现在雄性身上。从雄性橘猫占多数这一现象，科学家推测这种被称为"性连锁橘色"的突变位于X染色体上。任何携带该突变的雄性猫都会呈现全橘色，而雌性猫需要两条X染色体都携带该突变才会全橘——这种情况更为罕见。携带单拷贝突变的雌猫会呈现部分橘色——要么是玳瑁斑纹，要么是橘黑白相间的三花图案。这是由于雌性特有的X染色体随机失活现象，即每个细胞中有一条X染色体被关闭。这导致色素细胞形成镶嵌图案，部分表达性连锁橘色特征，部分则不表达。研究人员在 X 染色体上寻找雄性橘猫共有的变异，发现一个变异增加了 Arhgap36 基因在色素细胞中的异常表达。

之前以为压力板那张图是 P 的，结果还真是真的

在这么多公式问题里面，架子鼓是唯一一个可能有技术性解决方案的一个，因为“一套鼓”是组出来的，完全有可能手搓出第五套出来，下面我们来尝试一下……

520到了，一些会让男生觉得「无法对应」的各种小技巧！
1. CUDA OUT OF MEMORY
2. Runtime Error: type numpy().float cannot be added to value NaN
3. TypeError: l2_loss() got multiple values for argument 'size'
4. Warning: Values are very small
5. invalid_argument: XY too large when splitting the images
6. Runtime Error: 1.pth NOT FOUND
7. bad_alloc: tensor too large
8. 余额已不足训练24小时，请尽快充值

Fractalicious
I published my first Fractal on the 31st of December 2013. After that, 2014 has been a very Fractalicious year for me. Thanks to a very supportive community, I’ve produced some 20 little fractal clips that total more than an hour of running time. Currently…
