Extracting Alternative Solutions from Benders Decomposition
We show how to extract alternative solutions for optimization problems solved by Benders Decom- position. In practice, alternative solutions provide useful insights for complex applications; some solvers do support generation of alternative solutions but none appear to support such generation when using Benders Decomposition. We propose a new post-processing method that extracts multiple optimal and near-optimal solutions using the cut-pool generated during Benders Decomposition. Further, we pr…

On the extraction of Alcock-Paczynski signal from voids: a novel approach via reconstruction
The void galaxy cross correlation function is a powerful tool to extract cosmological information. Through the void galaxy cross correlation function, cosmic voids, the underdense regions in the galaxy distribution, are used for refined deductions of the Universe's content by correcting apparent geometric distortions. This study proposes a novel procedure for optimally extracting the Alcock Paczynski, AP, signal from cosmic voids through a cosmological reconstruction technique. Employing cosmol…

DCMI: A Differential Calibration Membership Inference Attack Against Retrieval-Augmented Generation
While Retrieval-Augmented Generation (RAG) effectively reduces hallucinations by integrating external knowledge bases, it introduces vulnerabilities to membership inference attacks (MIAs), particularly in systems handling sensitive data. Existing MIAs targeting RAG's external databases often rely on model responses but ignore the interference of non-member-retrieved documents on RAG outputs, limiting their effectiveness. To address this, we propose DCMI, a differential calibration MIA that miti…

Finished "Lobizona" by Romina Garber. I have extremely mixed feelings about this book. It's a powerful depiction of the fear of living as an undocumented child/teen and it has interesting things to say about rejection, belonging, and the choice between seeking to be recognized for who you are and wanting you blend in enough to be accepted as normal. However, it's also an explicit homage to Harry Potter, and while it doesn't include antisemitic tropes or glorify slavery or even have any anti-trans sentiments I can detect, to me the magical school setup felt forced and I thought it would have been a better book had it not tried to fit that mould. Also, it would have been a super interesting situation to explore trans issues, and while it's definitely fine for it not to do that, the author's praise of Rowling's work has me wondering...
There's a sequel that I think could in theory be amazing, but given the execution of the first book, I think I'll wait a bit before checking it out. By putting her main character in opposition to both ICE in the human world and the magical authorities in the other world, Garber explicitly sets the stage for a revolution standing between her protagonist and any kind of lasting peace. But I'm not confident she's capable of writing that story without relying on some kind of supernatural deus ex machina, which would be disappointing to me, since "a better world if only possible through divine intervention" is an inherently regressive message.
Overall, #OwnVoices fantasy centering an undocumented immigrant is an excellent thing, and I've certainly got a lot of privilege that surely influences my criticism. However, #OwnVoices stuff has a range of levels of craft and political stances, and it can be excellent for some reasons and mediocre for others.
On that point, if anyone reading this has suggestions for fiction books grappling with borders and the carceral state, Is be happy to hear them.

No Metallicity Preference in Fast Radio Burst Host Galaxies
Fast radio bursts (FRBs) are millisecond-duration extragalactic radio transients of unknown origin, and studying their host galaxies could offer clues to constrain progenitor models. Among various host properties, gas-phase metallicity is a key factor influencing stellar evolution and the production of transients. We analyze the largest uniformly selected sample of FRB host galaxies to date, measuring oxygen abundances (12+log(O/H) = 8.04-8.84) for 40 hosts using consistent emission-line diagno…

Drilling for fresh water under the salt water off Cape Cod, Expedition 501 extracted thousands of samples from what is now thought to be a massive, hidden aquifer stretching from New Jersey as far north as Maine.

Scientists tap fresh water under the sea, raising hopes for a thirsty world
Scientists conducting a first-of-its-kind drilling operation have extracted samples of fresh water hiding in massive reservoirs deep under the ocean. Their consortium of more than a dozen nations sank pipes through the seabed muck off Cape Cod this summer to see how old that water is, what organisms live in it and whether it is a renewable resource that could someday slake the planet’s growing thirst. Their search comes as the U.N. forecasts that the global demand for fresh water will exceed …
