@wjscheirer.bsky.social Can the conferences offer targeted subsidies to some attendees (e.g., students) to book rooms in conference hotels? Assuming attrition fees scale with number of unbooked rooms, that seems a better use of funds than simply paying them to the hotels and may be a win-win.

We also present a solution to the problem, showing how we can efficiently estimate 2nd order information and largely mitigate the poor conditioning, opening the door for efficient, SGD-based high resolution cryo-EM methods.

We show the numerical conditioning of cryo-EM reconstruction is increasingly poor at high resolution such that SGD has no real hope of resolving high resolution structures.

Definitely. None of those things automatically go away just because someone gives you a degree!

A very similar argument (start with a basic set of requirements/axioms) can be made to show that probabilities are basically the only logically consistent calculus of uncertainty, see en.wikipedia.org/wiki/Cox%27s...
