Nordic health catalogues miss key fields in data standard
Preprint: A review found none of 2,811 selected health-themed descriptions met all eight mandatory HealthDCAT-AP Release 7 properties.
Review Reports a Hidden Cost of Function in Protein Evolution
Preprint: A review says some protein positions face functional constraints beyond the need to stay folded.
Quantum Encoding Test Finds No Single Best Method
Preprint: A five-dataset simulation found that the strongest raw scores often came with higher circuit costs or weaker generalization.
PMFRec model leads recommendations for newly arriving items
An arXiv preprint reports that PMFRec led nearly all cold-item comparisons on CiteULike and XING, with gains of up to 7.56% over the strongest baseline.
AI editing method reports less collateral drift in benchmark tests
Preprint: KLOD reported highly reliable edits and strong preservation of unrelated predictions, while its threshold exposed a tradeoff with rephrased prompts.
AI editing leaves a different trail from AI generation
Preprint: A large English-language test found that AI-edited passages were more often mistaken for human than for fully AI-generated text.
Spiking language model gains ground in tests without reported collapse
An arXiv preprint reports stronger benchmark averages and steadier rollouts for SpikeOPD, but the evidence comes from computational tests, not hardware measurements or users.
Lightweight add-on helps vision models read fisheye images
An arXiv preprint reports better depth and segmentation scores after attaching Distortion Extenders to frozen perspective-trained models.
Dual-feedback AI system tops e-commerce design benchmark
Preprint: A Qwen3.5-9B model that generates complete HTML/CSS documents for e-commerce creatives scored 94.0 automatically and 90.0 in blind expert review.
New Handoff Method Shows Gains for AI Agent Success and Cost
Preprint: TACIT-SWITCH switches from cheaper to stronger models during multi-step tasks and reports gains in simulations and interactive tests.
AI system scores higher at matching people across ground and aerial views
Preprint reports a 22.28% pair F1 on A-PAIR, ahead of the strongest listed baseline, while only 12.54% of test samples met the paired-hit threshold.
AI text detector scores highly against rewrites, with caveats
Preprint: NeuroStat combines token-level signals with semantic representations, but its tests remain limited to English benchmark data.
Privacy-aware system flags ERP anomalies near centralised performance
The paper reports 93.5% F1 on an expert-annotated ERP evaluation, 94% less communication than FedAvg, and near-random success in tested privacy attacks.
AI Models Hit 99% Accuracy on New Movement Dataset
The study found very high window-level accuracy, but random overlapping windows and participant-mixed testing leave performance on unseen people unanswered.
Seoul study links VOC mixtures to more asthma and atopic dermatitis care
A citywide analysis found higher daily visits and admissions from 2015 to 2019, but its observational design cannot establish that VOCs caused either condition.
CT Study Finds Fat Texture Adds to Coronary Calcium Detection
In 1,736 adults without known coronary artery disease, texture features added information beyond total abdominal-fat area and varied by sex and fat depot.
Esaxerenone linked to fewer cardiovascular events than spironolactone
A Japanese health-record study found lower rates with esaxerenone, but its observational design cannot show that one drug caused the difference.
Study reports AI model separates malignant and benign laryngeal lesions
The retrospective evaluation found strong internal performance and attention aligned with physician-marked regions, but it did not test clinical benefit.
Ultrasound signs linked to growth in tiny thyroid nodules
A study linked blood flow and shear wave measures to past enlargement in 51 ACR TI-RADS 5 nodules measuring 10 millimeters or less.
