Salmincola californiensis is a freshwater parasitic copepod of Pacific salmon and trout (genus Oncorhynchus). While the duration its juvenile life stage – free-swimming copepodid (pictured here) lasts for only about 5 days at 16°C, this short time represents opportunity when members species can seek attach themselves to potential hosts. One way that copepods move in water column by executing se...

The search for new algorithms that could reduce the time needed multiplication is now at center of data science.

This paper introduces a new key space for CSIDH and algorithm constant-time evaluation of the group action. The is not useful with previous algorithms, spaces, but combining produces speed records CSIDH. For example, CSIDH-512 256-bit space, best results used 789000 multiplications more than 200 million Skylake cycles; this uses 438006 125.53 cycles.
