Successive Phase Transitions in the Quasi-Kagome Lattice System URhSn Studied by Resonant X-ray Scattering
Successive phase transitions in the quasi-kagome compound URhSn were investigated by resonant X-ray scattering (RXS) at the uranium $M_4$ edge. In the high-temperature phase between 16 K and 54 K, an additional RXS signal was detected superposed onto fundamental reflections in both $π$-$σ'$ and $π$-$π'$ polarization channels. Upon cooling below 16 K, reported as a ferromagnetic phase along $c$, substantial enhancements were observed again in the both polarization channels at the 300 reflect…

Value-Based Large Language Model Agent Simulation for Mutual Evaluation of Trust and Interpersonal Closeness
Large language models (LLMs) have emerged as powerful tools for simulating complex social phenomena using human-like agents with specific traits. In human societies, value similarity is important for building trust and close relationships; however, it remains unexplored whether this principle holds true in artificial societies comprising LLM agents. Therefore, this study investigates the influence of value similarity on relationship-building among LLM agents through two experiments. First, in a…

Laser ablated sub-wavelength structure anti-reflection coating on an alumina lens
We used laser ablation to fabricate sub-wavelength structure anti-reflection coating (SWS-ARC) on a 5 cm diameter alumina lens. With an aspect ratio of 2.5, the SWS-ARC are designed to give a broad-band low reflectance response between 110 and 290 GHz. SWS shape measurements conducted on both sides of the lens give 303 $μ$m pitch and total height between 750 and 790 $μ$m, matching or exceeding the aspect ratio design values. Millimeter-wave transmittance measurements in a band between 140 and…

Enhanced plasma heating via interaction with high-contrast laser and cone-shaped target
We investigated plasma heating enhancement using a high-intensity, high-contrast laser and a cone-attached target. Fast electron spectra and X-ray emission were measured with an electron spectrometer and a Bragg crystal spectrometer. The results were analyzed using PrismSPECT simulations with a two-component electron distribution model and empirical scaling laws. X-ray pinhole images showed that the cone effectively focused multi-spot laser light near its tip, enhancing local emission. While hi…

"Here is the thing: the video describes, at an excruciatingly slow pace (at least by the standards of our generation’s TikTok-formatted brains), with the terms and phraseology of 1968, and during no less than one and a half hours, the very computer you are using to read this article. Yes, the one on your lap or on your desk."

As in any human group, there are certain pilgrimages, certain rites of passage that all software developers apparently must go through. They are various and equally anecdotical: to compile and boot their own Linux kernel; to read "The Art of Computer Programming" in its entirety (and then send their CV to Bill Gates); to give a presentation in a conference; and finally, to sit through the whole duration of "The Mother of All Demos", the recording of the unavoidable presentation made by Douglas …

VideoConviction: A Multimodal Benchmark for Human Conviction and Stock Market Recommendations
Social media has amplified the reach of financial influencers known as "finfluencers," who share stock recommendations on platforms like YouTube. Understanding their influence requires analyzing multimodal signals like tone, delivery style, and facial expressions, which extend beyond text-based financial analysis. We introduce VideoConviction, a multimodal dataset with 6,000+ expert annotations, produced through 457 hours of human effort, to benchmark multimodal large language models (MLLMs) an…

Efficient Learning of Balanced Signed Graphs via Sparse Linear Programming
Signed graphs are equipped with both positive and negative edge weights, encoding pairwise correlations as well as anti-correlations in data. A balanced signed graph is a signed graph with no cycles containing an odd number of negative edges. Laplacian of a balanced signed graph has eigenvectors that map via a simple linear transform to ones in a corresponding positive graph Laplacian, thus enabling reuse of spectral filtering tools designed for positive graphs. We propose an efficient method t…

My morning so far:
- Essential system is not working, opened support ticket.
- Two hours later still no change.
- Called service desk: "Yes we assigned the ticket to the 2nd level"
- Checked ticket queue: "Priority 4: Low"
- Called service desk "Tell the 2nd level guys if they don't make this work before lunch we're coming over and confiscate every Switch 2 we find!"
