Analysis of Floating-Point Matrix Multiplication Computed via Integer Arithmetic
Ootomo, Ozaki, and Yokota [Int. J. High Perform. Comput. Appl., 38 (2024), p. 297-313] have proposed a strategy to recast a floating-point matrix multiplication in terms of integer matrix products. The factors A and B are split into integer slices, the product of these slices is computed exactly, and AB is approximated by accumulating these integer products in floating-point arithmetic. This technique is particularly well suited to mixed-precision matrix multiply-accumulate units with integer s…

Heute ist bei uns in #BadOeYnhausen das #Stadtradeln gestartet und ich habe letztes Jahr schon etwas dazu geschrieben, was sich auch in diesem Jahr nicht geändert hat:

NASA: May 2025 was the 2nd warmest May on record, globally: 1.07°C above the 1951-1980 average. Only May 2024 was warmer.
Highest anomalies in the Siberian Arctic, Central Asia, and the West-Antarctic.

P.S. Hat tip to @… for the radium reference. He was talking about other things (https://pluralistic.net/2024/09/19/just-stop-putting-that-up-your-ass/#harm-reduction), but the whole vibe of that “Radium will magically restore you to health!” era is by far the best historical comparison I’ve found for the current froth-mouthed AI hype.

Apache Point rapid response characterization of primitive pre-impact detection asteroid 2024 RW$_1$
Pre-impact detection asteroids (PIDAs) may be detected only a few hours before their impact with Earth, providing a brief opportunity to characterize them before impact. We describe the characterization of PIDA 2024 RW$_1$, which was discovered by the Catalina Sky Survey on 2024 September 4 at 05:43 UTC, before it entered the atmosphere near the northern Philippines at 16:39 UTC. We observed 2024 RW$_1$ with the Astrophysical Research Consortium Telescope Imaging Camera on the Apache Point Astr…

My removal from #nasa #nyc continued afoot.
I haven’t said much of it here — but my competitive grant proposals (nasa scientists get funded this way since full cost accounting hit in 2004) have been chosen, but not funded.
There is no grant money to distribute. Folks in the know have seen that - ROSES, the acronym for research opportunities in science, does not have a 2025 call and the 2024 chosen post January 2025 don’t have money getting distributed.
If I cannot get proposals funded I will be in the same situation as every other soft money researcher.
So the soft RIF is coming for me and 1000’s of others.

Proceedings of the 19th International Workshop on Logical and Semantic Frameworks, with Applications
This volume contains the post-proceedings of the 19th LSFA, which was held in Goiânia, the capital of Goiás state in Brazil, from September 18 to September 20, 2024. Logical and semantic frameworks are formal languages used to represent logics, languages and systems. These frameworks provide foundations for the formal specification of systems and programming languages, supporting tool development and reasoning. The aim of this series is bringing together theoreticians and practitioners t…

Ah, current plans for today: find some way to get Microsoft Flight Sim 2024 running on my computer. So far I've managed to select my starting airport/airfield and then the game hangs. It's progress, but I have a feeling this fight is going to go on for awhile considering the game hangs immediately afterwards.

Thinking Beyond Visibility: A Near-Optimal Policy Framework for Locally Interdependent Multi-Agent MDPs

Thinking Beyond Visibility: A Near-Optimal Policy Framework for Locally Interdependent Multi-Agent MDPs
Decentralized Partially Observable Markov Decision Processes (Dec-POMDPs) are known to be NEXP-Complete and intractable to solve. However, for problems such as cooperative navigation, obstacle avoidance, and formation control, basic assumptions can be made about local visibility and local dependencies. The work DeWeese and Qu 2024 formalized these assumptions in the construction of the Locally Interdependent Multi-Agent MDP. In this setting, it establishes three closed-form policies that are tr…

MOA-2022-BLG-091Lb and KMT-2024-BLG-1209Lb: Microlensing planets detected through weak caustic-crossing signals
The light curves of the microlensing events MOA-2022-BLG-091 and KMT-2024-BLG-1209 exhibit anomalies with very similar features. These anomalies appear near the peaks of the light curves, where the magnifications are moderately high, and are distinguished by weak caustic-crossing features with minimal distortion while the source remains inside the caustic. To achieve a deeper understanding of these anomalies, we conducted a comprehensive analysis of the lensing events. We carried out binary-len…

approximately no one's noticing but stack overflow is reaching its maximum number of questions.
that's because every day, every unanswered, unupvoted, uncommentedon question older than a year gets deleted (see the big jump up on the graph in April 2024). those deletions are now neck and neck with new questions coming in on weekdays. those deletions dwarf new questions coming in on weekends, so the site's already shrinking on weekends.

ILC250 Cost Update - 2024
The International Linear Collider was conceived as a global project for an energy-frontier electron-positron collider.It employs superconducting RF and nano-beam technologies with a center-of-mass energy of 500 GeV. Its cost was estimated in 2013, based on the Technical Design Report published in 2013.Japan's high-energy community proposed to host the ILC in Japan as a Higgs boson factory at 250 GeV in its first phase, and a revised cost estimate was conducted in 2017 to host it in Japan.
