A Ground-Based Transit Observation of the Long-Period Extremely Low-Density Planet HIP 41378 f
We present a ground-based transit detection of HIP 41378 f, a long-period ($P = 542$ days), extremely low-density ($0.09 \pm 0.02$ g cm$^{-3}$) giant exoplanet in a dynamically complex system. Using photometry from Tierras, TRAPPIST-North, and multiple LCOGT sites, we constrain the transit center time to $T_{C,6} = 2460438.889 \pm 0.049$ BJD TDB. This marks only the second ground-based detection of HIP 41378 f, currently the longest-period and longest-duration transiting exoplanet observed from…

Element nucleosynthetic origins from abundance spatial distributions beyond the Milky Way
An element's astrophysical origin should be reflected in the spatial distribution of its abundance, yielding measurably different spatial distributions for elements with different nucleosynthetic sites. However, most extragalactic multi-element analyses of gas-phase abundances to date have been limited to small numbers of sightlines, making statistical characterization of differences in spatial distributions of elements impossible. Here we use integrated field spectroscopic data covering the fu…

The stablecoin evangelist: Katie Haun's fight for digital dollars | TechCrunch
In 2018, when Bitcoin was trading around $4,000 and most Americans, at least, thought cryptocurrency was a fad, Katie Haun found herself on a debate stage in Mexico City opposite Paul Krugman, the Nobel Prize-winning economist. As Krugman focused on Bitcoin's wild price swings, Haun steered the conversation toward something else — stablecoins.

Trump has promoted his private businesses in unprecedented ways for a sitting president, presenting conflicts of interest.
His ventures into crypto, in particular, have drawn scrutiny because he has simultaneously moved to create a more friendly regulatory environment for the industry. 
The $57 million from his stake in the crypto firm World Liberty Financial came from the sale of digital tokens.
That provides a glimpse into Trump’s earnings from cryptocurrency ventures t…

HetGPU: The pursuit of making binary compatibility towards GPUs
Heterogeneous GPU infrastructures present a binary compatibility challenge: code compiled for one vendor's GPU will not run on another due to divergent instruction sets, execution models, and driver stacks . We propose hetGPU, a new system comprising a compiler, runtime, and abstraction layer that together enable a single GPU binary to execute on NVIDIA, AMD, Intel, and Tenstorrent hardware. The hetGPU compiler emits an architecture-agnostic GPU intermediate representation (IR) and inserts meta…

Large solutions to semilinear equations for subordinate Laplacians in $C^{1,1}$ bounded open sets
We study the existence of a large solution to a semilinear problem in a bounded open $C^{1,1}$ set for a class of nonlocal operators obtained by an appropriate subordination of the Laplacian. These operators are classical generalisations of the fractional Laplacian. The existence result is shown under a nonlocal version of the Keller-Osserman condition, stated in terms of the subordinator and the source term $f$.

Trump Was Already a Crypto Czar in 2024
Financial disclosures for 2024 filed by the president on Friday show that digital coins had already become one of his family’s most successful ventures.

For various reasons I get CCs of both sides of new system planning: the customer asking for vague stuff and hardware vendors providing precise quotes and my highly appreciated boss running both conversations.
It is very strange to watch our first “AI” system being defined. Customer built a prototype on a Mac and really doesn’t understand his needs or the constraints. He definitely doesn’t get that servers are different. Or that we aren’t
