"If you’re thinking all of this looks a lot like Musk trying to juice his #Tesla sales numbers—and therefore his Tesla stock share price—by playing a shell game with his own companies, you’re not alone. It isn’t quite the same as the disastrous special purpose entities that ultimately brought energy company #Enron

Cybertruck sales are so bad Musk is selling them to ... himself
You wanna see a dead body? Third-quarter sales numbers for Tesla’s misbegotten Cybertruck are in, and it is definitely spooky season for tech titan Elon Musk, who moved only 5,385 of the hideous ...

Compartmentalised Agentic Reasoning for Clinical NLI
A common assumption holds that scaling data and parameters yields increasingly structured, generalisable internal representations. We interrogate this assumption in clinical natural language inference (NLI) by adopting a benchmark decomposed into four reasoning families, Causal Attribution, Compositional Grounding, Epistemic Verification, and Risk State Abstraction, and introducing CARENLI, a Compartmentalised Agentic Reasoning for Clinical NLI that separates knowledge access from principled in…

The growth of magnetic energy during the nonlinear phase of the subsonic and supersonic small-scale dynamo
Small-scale dynamos (SSDs) amplify magnetic fields in turbulent plasmas. Theory predicts nonlinear magnetic energy growth $E_\mathrm{mag} \propto t^{p_\mathrm{nl}}$, but this scaling has not been tested across flow regimes. Using a large ensemble of SSD simulations spanning sub- to supersonic turbulence, we find linear growth ($p_\mathrm{nl} = 1$) in subsonic flows and quadratic growth ($p_\mathrm{nl} = 2$) in supersonic flows. In all cases, we find a dynamo efficiency of $\sim 1/100$ and a dur…

Diesen Jugend-Slang findet Autorin Ingrid Noll „strange“
Auch mit fast 90 ist die Autorin Ingrid Noll mit Jugendwörtern in Kontakt – und sie verwendet sie sogar in ihren Büchern. Dabei gab es schon in ihrer Jugend Anglizismen.

In August of 1977, Tim Horton was inducted into the Hockey Hall of Fame, just 3 years after losing his life in an automobile accident. Known as "the strongest man in hockey " during his career, he helped the Toronto Maple Leafs win 4 Stanley Cups. He would have been only notable with hockey nerds except for the fact that before he died, he was the namesake and primary investor for a Hamilton Ontario restaurant selling donuts and coffee. Today, most Canadians live within 100 metres of a Timmies and don't have a clue who the founder was, or that he died crashing his exotic sports car while drunk. (Insert tasteless joke about TimBits all over the QEW...)

Closed-form $\ell_r$ norm scaling with data for overparameterized linear regression and diagonal linear networks under $\ell_p$ bias

Closed-form $\ell_r$ norm scaling with data for overparameterized linear regression and diagonal linear networks under $\ell_p$ bias
For overparameterized linear regression with isotropic Gaussian design and minimum-$\ell_p$ interpolator $p\in(1,2]$, we give a unified, high-probability characterization for the scaling of the family of parameter norms $ \\{ \lVert \widehat{w_p} \rVert_r \\}_{r \in [1,p]} $ with sample size. We solve this basic, but unresolved question through a simple dual-ray analysis, which reveals a competition between a signal *spike* and a *bulk* of null coordinates in $X^\top Y$, yielding closed-form …

SecInfer: Preventing Prompt Injection via Inference-time Scaling
Prompt injection attacks pose a pervasive threat to the security of Large Language Models (LLMs). State-of-the-art prevention-based defenses typically rely on fine-tuning an LLM to enhance its security, but they achieve limited effectiveness against strong attacks. In this work, we propose \emph{SecInfer}, a novel defense against prompt injection attacks built on \emph{inference-time scaling}, an emerging paradigm that boosts LLM capability by allocating more compute resources for reasoning dur…
