Front-to-back defibrillator pad placement was slower and less accurate in simulation
Preprint: In linked simulations, anterior-posterior placement took 3.57 seconds longer than anterior-lateral placement, while acceptable anterior-lateral placement rose after written guidance.
Preprint Reports a Wider Spread of Magnetic Modes Under Pressure in Sr2IrO4
Raman measurements found magnetic excitations shifting in opposite directions under pressure, depending on crystal geometry and laser-spot location.
A mathematical framework tests when utility can be compared across people
An arXiv Preprint defines a shared utility unit, derives tests for comparability and presents different tax rankings under competing criteria.
New Maxwell solver reports nearly tenfold fewer iterations
Preprint tests report faster convergence and smaller interface mismatches in waveguide and filter models, but broader scaling remains unmeasured.
Analysis Finds Global Control for Two Abstract Wave Models
Preprint: A mathematical analysis reports global well-posedness at its stated Sobolev threshold and global H^1 solutions, while uniqueness at H^1 remains unproved.
Quantum measurement gains vary across benchmark circuits
Preprint: A computational framework links operator backpropagation with measurement choice, but its advantage changes across benchmark circuits.
Follow-up observations challenge lensing claims for two quasar candidates
Preprint: New data reclassify J0109–5424, while the authors do not favor lensing for P170+20 but cannot rule it out.
Edge LLM tests show speed varies by model, software and format
Preprint: Jetson measurements compare latency, throughput, power and energy across platforms, backends and numerical formats.
SPECTRA Leads TAPE Across Three Few-Shot Audio Benchmarks
An arXiv version 1 preprint dated 25 August 2026 reports higher average accuracy and a smaller performance drop for SPECTRA in standard tests with a frozen audio-language encoder.
A 50-Hz wobble blurs high-resolution views at SOAR
An arXiv preprint dated 25 August 2026 examines several kinds of vibration in Chile's 4.1-m SOAR telescope, but leaves the main 50-Hz source unresolved.
AI model improves forecasts of social-media cascade popularity
Preprint reports lower prediction errors across Twitter and Sina Weibo datasets, but tests remain limited to two data sources and selected time windows.
Interactive tool maps neutrino oscillations in three dimensions
Preprint: NuGlass links six browser-based 3D views and cross-checks its calculations across 42,000 parameter points.
Proposed framework sets stricter rules for AI in evidence reviews
Preprint: ARISMA treats AI as an inspected, benchmarked, logged and reversible assistant, with humans retaining control over consequential review decisions.
New Monte Carlo analysis finds finite-accuracy gains, not high-accuracy gains
Preprint: An HFHRMC analysis finds a finite-accuracy benefit from position diffusion, while its leading high-accuracy order matches optimized ULD.
Simulation finds strongest galaxy bias in node outskirts
Preprint: Simulated central galaxies had the strongest reported bias in node outskirts, while mean filament bias fell from short to long filaments.
Benchmark Finds Faster LLM-Generated Code for Some Database Queries
An arXiv preprint reports a 2.11× speedup in a 22-query TPC-H test, with results varying by model and query.
Preprint proves sharp area bound for simple polygons
A machine-checked theorem says one area gap is at least twice another, while a related optimum remains unresolved.
Exact norm sampling hinges on Hadamard matrices
Preprint: The unrestricted minimum is N when a Hadamard matrix of order N exists and N+1 otherwise; in two stated cases, strictly positive weights require more nodes.
Math Preprint Finds Large Families of Littlewood Counterexamples
A mathematical construction finds counterexample pairs with a badly approximable first coordinate and a full-dimensional set of qualifying first coordinates.
