Noise-Induced Collective Memory in Schooling Fish
Schooling fish often self-organize into a variety of collective patterns, from polarized schooling to rotational milling. Mathematical models support the emergence of these large-scale patterns from local decentralized interactions, in the absence of individual memory and group leadership. In a popular model where individual fish interact locally following rules of avoidance, alignment, and attraction, the group exhibits collective memory: changes in individual behavior lead to emergent pattern…

Continual Neural Topic Model
In continual learning, our aim is to learn a new task without forgetting what was learned previously. In topic models, this translates to learning new topic models without forgetting previously learned topics. Previous work either considered Dynamic Topic Models (DTMs), which learn the evolution of topics based on the entire training corpus at once, or Online Topic Models, which are updated continuously based on new data but do not have long-term memory. To fill this gap, we propose the Continu…

Kudos for mentioning trouble with the Niagara Board of Control. 🏅

Ashley King went to a bar on a Bali vacation in 2011, and woke up blind just a few days later
— a result of drinks spiked with methanol.
"I woke up in my hostel and I wasn't able to breathe. And shortly after I wasn't able to see,"
said King, a 32-year-old Calgary woman who is sharing her story in a new podcast called Static: A Party Girl's Memoir.
King was 19 at the time, on her last night in Bali before flying to New Zealand the next day.

Pointwise ergodic theorem along primes of the form $x^2 + ny^2$
This paper resolves the question of pointwise convergence for ergodic averages of a single function along the set of polynomial values of primes of the form $x^2 + ny^2$. Following the influential paper of Bourgain \cite{bourgain1989pointwise}, we employ the Hardy-Littlewood circle method where major arc and minor arc estimates for the set of prime ideals constitute the main novelty of the paper. We also prove that our convergence results cannot be extended to class of $L^1$ functions.

Soeben eine Absage einer booking.com -Unterkunft erhalten, wegen des medizinischen Assistenzhunds 🐕‍🦺 meiner Frau, und weil angeblich Booking.com die Beschränkung "mindestens 4 Nächte" nicht übernommen hätte.
Habe die Buchung storniert (zum Glück kostenfrei weil genügend früh), aber die Gastgeber auf das Behindertengleichstellungsgesetz hingewiesen.

Chemical vapor deposition synthesis of (GeTe)n(Sb2Te3) gradient crystalline films as promising planar heterostructures
Phase-change materials of the (GeTe)n (Sb2Te3) (GST) system are of high relevance in memory storage and energy conversion applications due to their fast-switching speed, high data retention, and tunable properties. Here, we report on a fast and efficient CVD-based method for the fabrication of crystalline GST films with variable Ge/Sb atomic content. In particular, the approach enables compositional control without changing the precursor, facilitating a gradient synthesis of Ge3Sb2Te6, Ge2Sb2Te…

How Many Instructions Can LLMs Follow at Once?
Production-grade LLM systems require robust adherence to dozens or even hundreds of instructions simultaneously. However, the instruction-following capabilities of LLMs at high instruction densities have not yet been characterized, as existing benchmarks only evaluate models on tasks with a single or few instructions. We introduce IFScale, a simple benchmark of 500 keyword-inclusion instructions for a business report writing task to measure how instruction-following performance degrades as inst…
