Physics of Binary Star Evolution -- from Stars to X-ray Binaries and Gravitational Wave Sources The majority of all stars are members of a binary system. The evolution of such binary stars and their subsequent production of pairs of compact objects in tight orbits, such as double neutron stars a...

Smoothed Particle Hydrodynamics in Astrophysics This review discusses Smoothed Particle Hydrodynamics (SPH) in the astrophysical context, with a focus on inviscid gas dynamics. The particle-based SPH technique allows an intuitive and simple formula...

here is an example of an invited comprehensive review which is the sort of review welcomed in most sections of arxiv

main issue with textbooks is copyright - undergraduate mass market textbooks basically may not be posted because of publisher rules

book chapters need to be "stand alone" chapters
a "teaser chapter" as an ad to sell the book is usually rejected

also apparent citation fraud

yeah looks AI generated, multiple indicators

did you send a formal complaint to arxiv?
we're tracking these down for removal and followup actions
helps to have a formal coauthor complaint

dude - then half the submissions will come in exactly 7 days...

do as Tom requests!

We’re getting so many journal submissions from people who think ‘it kinda works’ is the standard to aim for.

we've been fighting the growth of slop for some months and are taking additional measures as we have the capacity to do so

other repositories are getting hit worse,
as are a lot of journals

it will be interesting to see which journals will just take the page charges and let rip

When they kick down your front door
How you gonna come?

this is in fact to try to stem the flood of AI slop
one step of many

you don't see the stuff we catch and reject,
the amount of slop is rising sharply and is currently dominated by first time submitters from academic institutions, in a not healthy way

we need to survive the transition...

Furthermore, as I've previously noted, it is evidence that the authors did not check the LLM outputs. Hence, it is highly likely there are other errors in the paper. We should have zero tolerance and impose penalties. ArXiv is doing this.

On arXiv, an Influx of AI Slop Pits Surface Against Substance As LLMs manufacture a form of scholarship, presentation doesn’t mean what it used to. Ranjit Singh looks at how this threatens the open-access research repository arXiv, how its founder is fighting to...

Committee on Facilitating Interdisciplinary Research

lots of studies on this, mostly contradictory and shallow

here's a somewhat relevant NASEM report:

I'm trying to find scholars who have studied how scientists assimilate the discoveries of other scientists. I'm trying to understand the potential impact of AI-assisted acceleration of scientific discoveries beyond the short term. Can anyone point me to people and publications?

The Story behind the Science: Preprints of pandemic potential—how bioRxiv and medRxiv brought preprints to the life sciences | mBio When we launched medRxiv in mid-2019, we never could have anticipated that just a few months later, New York would be at the epicenter of a rapidly escalating global pandemic, and we would be handling hundreds of papers about a previously unknown virus every week. Articles about bioRxiv and medRxiv preprints would appear on the New York Times front page, and our team worked every waking hour, seven days a week, making rapid decisions about sometimes controversial work and disseminating results of COVID research to millions of readers around the globe. Along the way, we were called dangerous and irresponsible by some, wimps and censors by others, but most in the biomedical community valued the service, and even Anthony Fauci and the head of the WHO called attention to the importance of preprints.
