Exciton-polariton condensate develops coherence in two stages
Preprint: The condensate showed early growth, partial collapse and revival of coherence before entering a quasi-steady state extending across it.
Humanoid robot shows separate control of force and twisting
An arXiv preprint dated 26 Aug 2026 reports a controller tested in simulation and on a 23-degree-of-freedom Unitree G1 humanoid.
Phase maps expose hidden structure in modeled light scattering
A preprint proposes a two-index polarization phase that adds detail to simulated thin-film and chiral-sphere scattering maps.
Image AI Framework Reports Similar Accuracy With Less Data
An arXiv preprint reports a modular vision-transformer system that reached 85.83% ImageNet accuracy at 1.24 bits per pixel.
Adaptive retrieval preprint reports higher mAP with fewer vectors
Preprint: AdaptiveEmbed reported higher average mAP with around two embeddings per sample, compared with fixed-capacity baselines using 3 to 40 embeddings per sample.
Two-Room Simulation Shows Howling Suppression and Speech Trade-Off
Preprint: A two-room, three-terminal verification simulation showed qualitative howling suppression, while over-muting fragmented desired speech and reduced intelligibility.
RotDroid detected more Android rotation bugs in equal-budget tests
Preprint: With 30 minutes per app, RotDroid recorded more true bugs than DLD and a DOC-based method, but DOC reported slightly higher precision.
Metasurface reveals multiple topologies in entangled light
Preprint: OAM measurements exposed several distinct topological states from one high-dimensional quantum state.
New graph theory bounds sharpen the hunt for a fugitive
Preprint derives exact cop numbers for Fibonacci and Lucas cubes and improves a bound for finite median graphs.
AI Agents Make Early Drawing Gains, Then Often Lose Accuracy
Preprint: A 25-agent 2D benchmark found strong early progress but weak long-horizon correction, with a large gap to a data-policy reference.
AI tool builds 4D LiDAR labels without manual annotation
Preprint: A video model and sparse clicks produced labels on SemanticKITTI, while downstream scores remained below models trained on full ground truth.
Open Air-Combat Simulator Reports Faster Reinforcement-Learning Tests
Preprint: BVR Sim pairs heterogeneous aircraft models with a faster C++ backend, while its policy-transfer and multi-agent results remain limited.
Mathematicians Find a Long-Term Kink Shape After Wave Breaking
A preprint reports global existence and uniqueness in specified solution classes, and describes a kink-wave limit as density and singular energy fade.
A Learned Model Simulates Chemical Reactions in Fewer Steps
Preprint: A conditional flow model approximated finite-time reaction behavior and used far fewer reported simulation steps in synthetic tests.
Shared AI System Reports 83.4% Less Data in VQA Test
Preprint: In a seven-transmitter simulation, the system recorded 64.8% multi-view question-answering accuracy, but real-world deployment was not tested.
DCGC reports top score on five of six benchmarks
Preprint: The masked-diffusion framework uses imperfect upstream solutions as auxiliary context and was evaluated on solver-failure benchmark sets.
Model suggests Punctum could be a primordial black hole
Preprint: An analytic model matches Punctum’s millimeter properties under a dark-matter spike scenario, but it does not confirm the object’s identity.
Framework connects p-adic reduction and uniformization
Preprint: Theorem-level results tie monodromy, Galois representations and p-divisible groups to the study of abeloid varieties.
Preprint Reports Two Modified Neutrino Textures Matching Key Ranges
The arXiv analysis leaves Vb′ and Vc′ compatible with quoted NuFIT 6.1 and JUNO intervals, but only for normal ordering.
