Att "The Anti-Autocracy Handbook - A Scholars’ Guide to Navigating Democratic Backsliding" ens existerar är i sig självt olycksbådande, och läsningen fångar mig. Nedmonteringen av USA:s demokratiska institutioner går fort och långsamt på en och samma gång.
Jag reflekterar på bloggen över konsekvenserna av den svåra och problematiska utveckling som syns i USA, inte minst för forskare och akademin, och ger några tankar om vad vi behöver göra.

Simplicial properadic homotopy
In this paper, we settle the homotopy properties of the infinity-morphisms of homotopy (bial)-gebras over properads, i.e. algebraic structures made up of operations with several inputs and outputs. We start by providing the literature with characterizations for the various types of infinity-morphisms, the most seminal one being the equivalence between infinity-quasi-isomorphisms and zig-zags of quasi-isomorphisms which plays a key role in the study the formality property. We establish a simplic…

Handoff Design in User-Centric Cell-Free Massive MIMO Networks Using DRL
In the user-centric cell-free massive MIMO (UC-mMIMO) network scheme, user mobility necessitates updating the set of serving access points to maintain the user-centric clustering. Such updates are typically performed through handoff (HO) operations; however, frequent HOs lead to overheads associated with the allocation and release of resources. This paper presents a deep reinforcement learning (DRL)-based solution to predict and manage these connections for mobile users. Our solution employs th…

Cohomology, Homotopy, Extensions, and Automorphisms of Nijenhuis Lie Conformal Algebras
This paper explores various algebraic and homotopical aspects of Nijenhuis Lie conformal algebras, including their cohomology theory, $\mathcal{L}_\infty$-structures, non-abelian extensions, and automorphism groups. We define the cohomology of a Nijenhuis Lie conformal algebra and relate it to the deformation theory of such structures. We also introduce $2$-term Nijenhuis $\mathcal{L}_\infty$-conformal algebras and establish their correspondence with crossed modules and $3$-cocycles in the coho…

A reader reports that when the patient died, the attending doctor
recorded the following on the patient's chart: "Patient failed to fulfill
his wellness potential."
Another doctor reports that in a recent issue of the *American Journal
of Family Practice* fleas were called "hematophagous arthropod vectors."
A reader reports that the Army calls them "vertically deployed anti-
personnel devices." You probably call them bombs.

Free summer music festival announces full lineup with 136 Austin acts #MusicNews

Hot Summer Nights announces full lineup with 136 Austin acts
Hot Summer Nights, Austin's donation-based festival across the Red River Cultural District (RRCD), is nearly here. From July 24-26, more than 140 acts will play at more than 15 venues on Red River Street, the city's hub for local live music. RRCD has just announced its full lineup, with 136 names and a handful more to come.

Baby's First #AmateurRadio #FieldDay! I ran the GOTA station for a few minutes to warm it up, and again in the early morning after the night crew were done for a handful of QSOs, but I spent many hours in the CW tent. At the start I just froze up and needed lots of help from th…

Sam Altman: "What if an inhuman AI took control of the world by manipulating people's behavior but its core directive was to make paper clips and it burned down the planet to do that? This is so scary and it's a real thing you should be worried about!"
Governments: "Oh boy that's scary we'll make special rules to invest in your company so you can save us from this frightening possibility. Will we restrict or discourage AI use/development? Haha no that would be foolish!"
Me: "What if an inhuman handful of corporate charters took control of the world by manipulating human behavior but their core directive was to maximize venture capital and they burned down the planet to do that? ..."
Governments (sponsored by said corporations): "Send in the SWAT teams now, this idea is dangerous!"

No lolly for me! Today’s #NYTSpellingBee felt like a bit of a slog as I brute-forced a handful of holdouts to reach #QueenBee—and grumbled at the irritating omissions. 🍭

I got Queen Bee!
