Rapid heat assisted polarization reversal in ferroelectric thin films
We demonstrate that switching of ferroelectric thin-films sandwiched between metallic electrodes can be controlled by laser-assisted heating, reminiscent of heat-assisted magnetic recording. We employ electrical switching cycles that quantify the electrically switchable remanent polarization $P_\mathrm{r}$ and show that 300\,ns voltage pulses alone change the polarization by less than $ΔP

Stitch: Training-Free Position Control in Multimodal Diffusion Transformers
Text-to-Image (T2I) generation models have advanced rapidly in recent years, but accurately capturing spatial relationships like "above" or "to the right of" poses a persistent challenge. Earlier methods improved spatial relationship following with external position control. However, as architectures evolved to enhance image quality, these techniques became incompatible with modern models. We propose Stitch, a training-free method for incorporating external position control into Multi-Modal Dif…

I wanted to weigh up flying versus taking the train for my trip to the Christmas party in Hamburg this year. The airport is BSL (EuroAirport Basel-Mulhouse). How hard can it be to find the price of a train ticket to the airport? Surprisingly hard, whether on bahn.de or sbb.ch

I will point out that this match commentary sums up some of my frustration with officiating, different competitions be damned.
#LFC conceded beyond the declared stoppage time to lose at Selhurst Park. A substitution in stoppage time allowed the referee's discretion to continue a full minute beyond. 👍
Gamed by "acute" cramping, conveniently timed when the ball is out of bounds …

Nice vertices in cubic graphs
A subgraph $G'$ of a graph $G$ is nice if $G-V(G')$ has a perfect matching. Nice subgraphs play a vital role in the theory of ear decomposition and matching minors of matching covered graphs. A vertex $u$ of a cubic graph is nice if $u$ and its neighbors induce a nice subgraph. D. Král et al. (2010) [9] showed that each vertex of a cubic brick is nice. It is natural to ask how many nice vertices a matching covered cubic graph has. In this paper, using some basic results of matching covered gra…

When Instructions Multiply: Measuring and Estimating LLM Capabilities of Multiple Instructions Following
As large language models (LLMs) are increasingly applied to real-world scenarios, it becomes crucial to understand their ability to follow multiple instructions simultaneously. To systematically evaluate these capabilities, we introduce two specialized benchmarks for fundamental domains where multiple instructions following is important: Many Instruction-Following Eval (ManyIFEval) for text generation with up to ten instructions, and Style-aware Mostly Basic Programming Problems (StyleMBPP) for…

As a non-binary person living in #Bergen, #Norway, this video made me cry from pure euphoria, a wave of relief knowing I am seen just as I am.
I hope it brings you the same confidence and happiness, showing that you are truly seen and celebrated for who you are.

Signless Laplacian characterization of cones over disjoint unions of cycles, edges and isolated vertices
Two graphs are said to be $Q$-cospectral if they share the same signless Laplacian spectrum. A simple graph is said to be determined by its signless Laplacian spectrum (abbreviated as DQS) if there exists no other non-isomorphic simple graph with the same signless Laplacian spectrum. In this paper, we establish the following results: (1) Let$G \cong K_{1} \vee \bigl(C_{k} \cup qK_{2} \cup sK_{1}\bigr),$ with $q,s \geq 1$, $k \geq 4$, and at least $21$ vertices. If $k$ is odd, then $G$ is DQS.…

An iterative-bijective approach to asymmetric generalizations of Schur's theorem
In this paper, we present a new Rogers--Ramanujan type identity for overpartitions by extending the asymmetrical version of Schur's theorem due to Lovejoy to a broader class of infinite products. More precisely, we provide a combinatorial interpretation of the following product, for any positive integer $k$, as a generating function for a class of overpartitions in which parts appear in $2^k - 1$ colors: \[ \frac{(-y_1 q;q)_\infty \cdots (-y_k q;q)_\infty}{(y_1 d q;q)_\infty}. \] Our proof is b…
