OneChronos And Auctionomics Launch First Auction Market For GPU Compute
Startup OneChronos teamed up with prize-winning economist Paul Milgrom of Auctionomics to develop the world's first financial market for GPU compute. Now comes the hard part.

The proposal to "Drop 32-bit multilib support on x86_64 #Fedora Linux and stop building packages for i686"[1] has been withdrawn:

Attached: 1 image PNG is back! https://www.programmax.net/articles/png-is-back/ (by Chris Blume) A new PNG spec was just released! […] […] After 20 years of stagnation, PNG is back with renewed vigor! What's new? * Proper HDR support (future‐proof, too!) * Finally recognizes APNGs (animations!) * Officially supports Exif data * General tidying up—fixing errata, clarifications, etc. #png

Detecting Atmospheric CO2 Trends as Population-Level Signatures for Long-Term Stable Water Oceans and Biotic Activity on Temperate Terrestrial Exoplanets
Identifying key observables is essential for enhancing our knowledge of exoplanet habitability and biospheres, as well as improving future mission capabilities. While currently challenging, future observatories such as the Large Interferometer for Exoplanets (LIFE) will enable atmospheric observations of a diverse sample of temperate terrestrial worlds. Using thermal emission spectra that represent conventional predictions of atmospheric CO2 variability across the Habitable Zone (HZ), we assess…

Monotone Bounded-Depth Complexity of Homomorphism Polynomials
For every fixed graph $H$, it is known that homomorphism counts from $H$ and colorful $H$-subgraph counts can be determined in $O(n^{t+1})$ time on $n$-vertex input graphs $G$, where $t$ is the treewidth of $H$. On the other hand, a running time of $n^{o(t / \log t)}$ would refute the exponential-time hypothesis. Komarath, Pandey and Rahul (Algorithmica, 2023) studied algebraic variants of these counting problems, i.e., homomorphism and subgraph $\textit{polynomials}$ for fixed graphs $H$. Thes…

Evaluating First-Principles Electron-Phonon Couplings: Consistency Across Methods and Implementations
Electron-phonon coupling (EPC) is fundamental for understanding the behavior of molecules and crystals, influencing phenomena such as charge transport, energy transfer, phase transitions, and polaron formation. Accurate computational methods to calculate EPCs from first principles are essential, but their complexity has resulted in a variety of computational strategies, raising concerns about their mutual consistency. In this study, we provide a systematic benchmark of methods for EPC calcula…
