I would just leave the country in which there is a financial crisis in higher education. In fact, I have.

To explore this further we need models that can exhibit both tipping and gradual transitions in biodiversity. The cross-feeding model proposed here is a very simple model that fills this need.
Of course there is still much room for improvement, but this is how far we got.

There is another reason why this is interesting. Presently there is a debate whether or when biodiversity in diverse systems can actually tip. See for example this paper by @hillebr1.bsky.social et al.

In the lab we then supply the community with growth media which supply some of the metabolites. This effectively removes these metabolites as limiting requirements. So this can be also modelled as an attack: C(x)->C(B(x)), where B describes the medium.

Why is this interesting: First, it shows why diversity tends to collapse in small samples. By missing some of the producers of metabolites we can cross the tipping point. In the equations we can model this effect of sampling as an attack on the network: We replace M(x)->M(A(x)).

Of course this is the classic two-folds scenario of tipping, so when we vary a second parameter (e.g. mean number of producers per metabolite), we find a nice Cusp bifurcation. This shows that the transition from high diversity to low diversity can occur by tipping/gradually depending on params...

For reasonable choices of parameters this system exhibits tipping points between a low and high diversity state ...

So this becomes a percolation problem. The whole setup is captured by two nice eqs. Here c* is num of bacteria chance m^* is num of metabolites, and C, M, are the GFs for number of requirements, number of producers per metabolite ...

So this becomes a directed bipartitie network, but if you want you can also think of it as a multilayer net or hypergraph.
What fascinates me is the algebraic structure: Bacteria in the system need ALL their requirements to be met, whereas metabolites need ONE of their producers to be present...

So this is about about crossfeeding, that is the exchange of molecules between bacteria. Think of this as a network where each node is a species of bacteria or a type of metabolite. Directed links indicate which metabolites are required by, or produced by the bacteria. ...

Indoors I use the same shure MV as everybody, but I do most of my videos outside, which also solves this.

As a creator I would say green screen is hard to get right consistently. However the main issue with bad space is in my experience reverb not visuals.

Thinking about this as well... In your examples: if r(x) is a solution to the first isn't s=r(log_2(x)) a solution to the second?

Of course not all of this money disappeared in two days. Eventually, it will slowly be burned up as resources are wasted on reshoring and production with less efficient supply chains. Right now the stock market only anticipates this loss. So there might still be a chance to fix this.

So where are the six trillion? They are burning up. Trump's 'reshoring' destroys the highly specialized international supply chains that make things cheap, so everything becomes more expensive, and conversely we have effectively less money. So there it goes.

These complex supply networks cannot exist in any single countries, there can simply not enough businesses to produce everything with a high degree of specialization in one place. This is what drove globalization. (It is also the reason why Brexit never had a chance of working).
comment in response to

The answer is massive division of labor between highly specialized manufacturers. This creates huge 'ecomony-of-scale' savings. Therefore even simple things are nowadays produced by complex supply networks. This reduces competition but also greatly brings down production costs.

First, consider washing machines. I only need to work ca. 15h to earn enough to buy a half-decent one. That's a bargain; I certainly couldn't build one in this time, not from raw materials in any case. But apparently someone can build one for much less than the value of 15h of my time. How?

SFI is great, always has been, and I would love to visit again. I still consider it an amazing place. However, I don't want to travel to the US in the current climate.
