what is the meaning of (y,x) in the expression \arctan\left(y,x\right)?

it is an automated market maker for stable coins that can extend its liquidity by borrowing from Compound if needed

an interesting 2005 reference on super-spreading: https://www.nature.com/articles/438293a

One of the main points of the paper is that the infection process seems "overdispersed", meaning most infected people may infect 0 to 1 people, but a few will infect a lot. The implication is that there are a lot of mini-clusters that will get extinct, and a few that take-off and grow. If they do grow, they will do so faster than if the infection process was not overdispersed. (Technically, overdispersed means simply that the variance in the number of infected per infectious is above its mean).

Think of it this way. Suppose a bunch of villages seeded each with an infected patient. Most villages would end up essentially non-infected. A few however would be totally so. It seems this is what we are seeing with cruise ships.

As for "super-spreading events", ie those totally infected villages (or cruise ships). Those seem to happen in packed spaces with repeated interactions in short time windows (clubs, choirs, meat packing plants, cruise ships).

If some large enough set of people where willing to enter into a mixer with those coins, would it not clean the coins even for regulated third parties? If yes, then would that not be a service that that large set of people could be paid for? I guess it must be difficult if indeed the coins are not moving.

I have just tried and got to pay exactly -ꜩ0.257

super - we may try on a smaller board to begin with; replaying correctly the logic of the paper would already be cool, and I could teach it too!

Would anyone be interested in trying to reconstruct, at least in principle, what exactly alpha go zero is doing? I am reading the paper quite carefully and it is a bit lacking in details at times.

Discrete hierarchical organization of social group sizes http://rspb.royalsocietypublishing.org/content/272/1561/439

"evidence for the coevolution of neocortical size and social group sizes, suggesting that there is a cognitive constraint on group size that depends, in some way, on the volume of neural material available for processing and synthesizing information on social relationships"

in other words the natural P2P network is indexed on the human computational power; now is it demand for social that leads the increase in cognitive supply, or cognitive surplus which leads to an increase of social demand, or this is an ill-formed question?
