GaN study finds emitters at interface and a target depth
Preprint: An emitter was observed at the depth of a low-temperature GaN layer in a design targeting 5 micrometres below a sapphire surface, while natural emitters aligned with the GaN-sapphire interface.
AI Recovery Method Reports Fewer Hidden Attacks in Hardware Code
Preprint reports lower attack rates and higher functional scores after teacher-student recovery, but tests used synthetic poisonings and fixed benchmarks.
A Mathematical Model Puts a Value on Human Expertise
An arXiv v1 preprint dated 26 Aug 2026 asks whether a decision-maker’s belief can improve worst-case choices when key parameters are unknown.
Sparse expert model reports gains against three attack norms
An arXiv preprint reports higher combined accuracy for Robust CurveMoE than the strongest named baseline across three tested threat models on CIFAR-100 and ImageNet-100.
New Preprint Finds Polynomial Rings Can Lose a Finiteness Property
Explicit constructions show that the strong finite type property can fail after one polynomial variable is added, with examples across several characteristics.
Linear multiphase-flow method shows stability, but one cavity test fails
Preprint: A second-order linear scheme reports near-second-order time accuracy and stable benchmark runs, but an unregularized cavity case loses boundedness.
Numerical method recovers scattering data from dark solitons
Preprint: A 26 August 2026 arXiv version extends the classical Boffetta–Osborne transform and tests it on three modeled dNLSE wave fields.
New analysis improves row-coreset bounds for subspace problems
Preprint: The analysis reports ε⁻² accuracy dependence in both p<2 and p>2 settings, but the p>2 rank-accuracy comparison remains open.
LoRA theory ties adapter rank to attention error
Preprint: A mathematical framework derives conditional error bounds for matching a fixed attention target, but does not predict task performance.
Rotating Noise Linked to Topological Fluctuations in a Lattice
Preprint: A theoretical study reports Chern topology in fluctuation bands even when the deterministic mechanics and noise spectrum are each topologically trivial.
Preprint reports linear filling bounds at and above asymptotic rank
The result applies to complete CAT(0) spaces with finite asymptotic rank and finite asymptotic Nagata dimension, under a stated dimensional threshold.
AI course reports rising grades over three years, but cause is unclear
A preprint describes a University of Arkansas thermal-engineering course that combines AI lessons with student-led projects.
A Single Robot Policy Works Across Robot Bodies, but Transfer Slips
This preprint reports strong benchmark scores and controlled tests with a Piper robot from one model trained on real-robot, simulated and human-hand data, but direct transfer to an ARX robot reached 35%.
Whisper posts a 37.5% word error rate in Baniwa study
A version 1 arXiv preprint reports an initial Baniwa speech-recognition baseline from 32.4 minutes of manually transcribed audio, mostly isolated words and short utterances.
Quantum protocol reaches limit for cleaning noisy unitary channels
An arXiv preprint reports a parallel design that matches the best sequential limit for certain query counts in a low-noise model.
Jet-Flow Study Finds AI Model Choice Matters by Task
A preprint comparison found neural networks suited scalar response maps, while reduced dynamics extended field predictions to unsimulated spacings.
Preprint builds meromorphic exception to half-plane value rule
A theoretical construction omits 0, 1 and infinity in each half-plane, yet is not of bounded type there.
A neutrino model links CP violation to strong-CP constraints
Preprint: Branch-dependent calculations connect the leptonic phase, neutrino mass and a tiny parity-breaking parameter.
Lab tests trace how earthquake slip pulses grow and fade
Preprint: Laboratory tests found the pulse patterns expected by a two-dimensional friction theory under several controlled fault conditions.
