The Illusion of Thinking: Understanding the Strengths and Limitations of Reasoning Models via the Lens of Problem Complexity
Recent generations of frontier language models have introduced Large Reasoning Models (LRMs) that generate detailed thinking processes…

Citizen science illuminates the nature of city lights: #LightPollution

DO HO SUH: WALK THE HOUSE. This is startlingly good. Really worth a trip to see the exhibition at Tate Modern, if you are anywhere near. It's rare to come across innovative modern art that is so soothing, not shocking or disturbing. These rooms are all made from thin, translucent fabric held up on wire frame, complete with all the familiar fittings.

A Random Matrix Theory of Pauli Tomography
Quantum state tomography (QST), the process of reconstructing some unknown quantum state $\hatρ$ from repeated measurements on copies of said state, is a foundationally important task in the context of quantum computation and simulation. For this reason, a detailed characterization of the error $Δ\hatρ= \hatρ-\hatρ^\prime$ in a QST reconstruction $\hatρ^\prime$ is of clear importance to quantum theory and experiment. In this work, we develop a fully random matrix theory (RMT) treatment of…

Framework of a multiscale data-driven digital twin of the muscle-skeletal system
Musculoskeletal disorders (MSDs) are a leading cause of disability worldwide, requiring advanced diagnostic and therapeutic tools for personalised assessment and treatment. Effective management of MSDs involves the interaction of heterogeneous data sources, making the Digital Twin (DT) paradigm a valuable option. This paper introduces the Musculoskeletal Digital Twin (MS-DT), a novel framework that integrates multiscale biomechanical data with computational modelling to create a detailed, patie…

Using gridpoint relaxation for forecast error diagnostics in neural weather models
Deep-learning (DL) weather prediction models offer notable advantages over traditional physics-based models, including auto-differentiability and low computational cost, enabling detailed diagnostics of forecast errors. Using our convolutional encoder-decoder model, ConvCastNet, we systematically relax selected subdomains of the forecast fields towards "true" weather states (ERA5 analyses) and monitor the forecast skill gain in other regions. Our results show that an 8-day midlatitude forecast …

Two axes in non-commutative algebras with a Frobenius form
Throughout this paper $A$ is a commutative non-associative algebra over a field $\mathbb{F}$ of characteristic not $2.$ In addition $A$ posses a Frobenius form. We obtain detailed information about the multiplication in $A$ given two axes of type half in $A.$
