Uniformly-S-projective relative to a module and its dual
In this article, we introduce the notion of u-S-projective relative to a module. Let S be a multiplicative subset of a ring R and M an R-module. An R-module P is said to be u-S-projective relative to M if for any u-S-epimorphism f : M \to N, the induced map HomR(P, f) : HomR(P,M) \to HomR(P,N) is u-S-epimorphism. Dually, we also introduce u-S-injective relative to a module. Some properties of these notions are discussed. Several characterizations of u-S-semisimple modules in terms of these no…

Day 7: Brenda Romero
I hinted yesterday I'd be moving beyond a narrow definition of "author," so of course that means I'm going to include game designers. I'll definitely get back to some more traditional authors before I hit 20, but I wanted to mix things up early.
Brenda Romero is something of a celebrity in the niche culture that is the Game Developers Coherence, I like to imagine. Of course the misogyny there likely means many just pay attention to who her husband is, but she's a terrific designer in her own right, if not prolific.
Content warning: the Holocaust
To me her most outstanding game has always been "Train," which is an exhibition tabletop game in which players collaborate to load and unload cargo and move train cars around a board, with the stated objective of efficiently delivering cargo to meet certain collective goals. However, through both physical cues and in-game reveals, it becomes clear to players that the game they are playing stimulates the Holocaust, and the cargo they're moving is people being brought to extermination camps. The actual goal of the game is for the players to stop playing and walk away, or perhaps to play against the stated objective and gridlock the trains. Romero supervised play at the expos where it was presented, and intervened to stop the game if the players continued too far (in some cases not picking up on the hints offered because they had very little knowledge of the Holocaust as a historical event). I've never played the game myself; just heard Romero give a report about it, but the sheer genius of designing a game meant not to be played to help educate about a system within which defying the rules was the only ethical action earned her instant respect from me. Romero has a whole series of games in this vein about didn't historical events (not necessarily all designed to not be played), although last I checked in most are just at prototyping stages.
I've got other non-man game designers that will appear on this list, but Romero stood out to go first because she's a good example that you don't need to be someone prolific or widely-known to do great work; I'd bet most people have an author or two they respect who is not widely known (and I'll include at least one more from that category on this list).

Road map for the tuning of hadronic interaction models with accelerator-based and astroparticle data
In high-energy and astroparticle physics, event generators play an essential role, even in the simplest data analyses. As analysis techniques become more sophisticated, e.g. based on deep neural networks, their correct description of the observed event characteristics becomes even more important. Physical processes occurring in hadronic collisions are simulated within a Monte Carlo framework. A major challenge is the modeling of hadron dynamics at low momentum transfer, which includes the initi…

Trump imposed 50% tariffs on most US imports from India,
making good on a threat to punish one of the world’s largest economies over its purchases of discounted Russian oil.
The tariffs, which came into effect just after midnight on Wednesday in Washington,
risk inflicting significant damage on the Indian economy and further disrupting global supply chains.
US tariffs of 25% on Indian goods went into force earlier this month,
but Trump announced plans to double …

Prospects for EMRI/MBH parameter estimation using Quasi-Periodic Eruption timings: short-timescale analysis
Quasi-Periodic Eruptions (QPEs) are luminous, recurring X-ray outbursts from galactic nuclei, with timescales of hours to days. While their origin remains uncertain, leading models invoke accretion disk instabilities or the interaction of a massive black hole (MBH) with a lower-mass secondary in an extreme mass ratio inspiral (EMRI). EMRI scenarios offer a robust framework for interpreting QPEs by characterizing observational signatures associated with the secondary's orbital dynamics. This, in…

Last month, China hosted its first International Advanced Air Mobility Expo,
showcasing its ambitions to dominate what Beijing calls the
“low-altitude economy,”
a fast-growing sector in the airspace below 3,000 meters (about 9,840 feet)
that includes drone deliveries, electric air taxis, and other uncrewed aerial services.
The event featured cutting-edge technologies
such as the world’s first seven-seat, three-ton electric vertical takeoff-and-landing airc…
