Engineering atomic superradiance scaling in cavity QED system with collective and individual emission channels
The coherent emission of multiple atoms gives rise to superradiance, a cornerstone phenomenon in quantum optics with wide-ranging applications in quantum information processing and precision metrology. Despite its importance, how the superradiant scaling with respect to the number of participating atoms can be effectively controlled remains largely unexplored. In this work, we investigate a cavity-QED system and demonstrate that atom-photon coupling can significantly alter the emission behavior…

Universal scaling of shear thickening suspensions under acoustic perturbation
Tuning shear thickening behavior is a longstanding problem in the field of dense suspensions. Acoustic perturbations offer a convenient way to control shear thickening in real time, opening the door to a new class of smart materials. However, complete control over shear thickening requires a quantitative description for how suspension viscosity varies under acoustic perturbation. Here, we achieve this goal by experimentally probing suspensions with acoustic perturbations and incorporating their…

TALP-Pages: An easy-to-integrate continuous performance monitoring framework
Ensuring good performance is a key aspect in the development of codes that target HPC machines. As these codes are under active development, the necessity to detect performance degradation early in the development process becomes apparent. In addition, having meaningful insight into application scaling behavior tightly coupled to the development workflow is helpful. In this paper, we introduce TALP-Pages, an easy-to-integrate framework that enables developers to get fast and in-repository feedb…

Quenched and Annealed CLTs for the one-periodic Aztec diamond in random environment
We study the asymptotic behavior of random dimer coverings of the one-periodic Aztec diamond in random environment. We investigate quenched limit theorems for the height function and we extend annealed limit theorems that were recently studied in [arXiv:2507.08560]. We consider more general choices of random edge weights (independence is not assumed) and we distinguish two cases where the random edge weights satisfy the Central Limit Theorem (CLT) under different scalings. For both cases, we pr…

Print Book Sales Rose Slightly in 2025
A mild rebound in children’s book sales helped to offset softness on the adult side, resulting in a 0.3% increase in unit sales of print books in 2025 over 2024. The Let Them Theory by Mel Robbins was last year’s top-selling title.

Semiclassical analytical solutions of the eigenstate thermalization hypothesis in a quantum billiard
We derive semiclassical analytical solutions for both the diagonal and off-diagonal functions in the eigenstate thermalization hypothesis (ETH) in a quarter-stadium quantum billiard. For a representative observable, we obtain an explicit expression and an asymptotic closed-form solution that naturally separate into a local contribution and a phase-space correlation term. These analytical results predict the band structure of the observable matrix, including its bandwidth and scaling behavior. W…

I have such conflicted thoughts on this.
What happened? Gross. It's very much a harm as a systemic effect of "AI"
But also _open source industry_ is in fact a thing I think has been deeply destructive and somewhat replaced the collectivist work done before. We could go back to that. That was good stuff.
But TailwindCSS is super popular.
I also think it's a bad technology, meant to undermine the foundations and design of CSS, leading us to technically worse places.
Also the business? It is selling themes and components.
That's a really hard business to be in. The time to buy a license comes in a project's lifecycle too early, so people avoid it. It's a weird business. Not one I think people should plan to have work.

Smishing messages like these exploit trust and urgency, making us act before we think.

Abstract: Reinforcement learning (RL) enables adaptive behavior across species via reward prediction errors (RPEs), but the neural origins of species-specific adaptability remain unknown. Integrating RL modeling, transcriptomics, and neuroimaging during reversal learning, we discovered convergent RPE signatures - shared monoaminergic/synaptic gene upregulation and neuroanatomical representations, yet humans outperformed macaques behaviorally. Single-trial decoding showed RPEs guided choices similarly in both species, but humans disproportionately recruited dorsal anterior cingulate (dACC) and dorsolateral prefrontal cortex (dlPFC). Cross-species alignment uncovered that macaque prefrontal circuits encode human-like optimal RPEs yet fail to translate them into action. Adaptability scaled not with RPE encoding fidelity, but with the areal extent of dACC/dlPFC recruitment governing RPE-to-action transformation. These findings resolve an evolutionary puzzle: behavioral performance gaps arise from executive cortical readout efficiency, not encoding capacity.

The Justice Department has backed off a dubious claim about President Nicolšs Maduro that the Trump administration promoted last year in laying the groundwork to remove him from power in Venezuela
-- that he leads a #drug #cartel called "Cartel de los Soles".
That claim traces back to a 2020 grand jury …

Justice Dept. Drops Claim That Venezuela’s ‘Cartel de los Soles’ Is an Actual Group
Last year, before capturing President Nicolás Maduro, the Trump administration designated a Venezuelan slang term for drug corruption in the military as a terrorist organization and said he led it.
