Machine-learned sepsis score separates ICU survivors from non-survivors
Preprint analysis finds an hourly score can track changing physiology, but agreement falls when it is moved between hospitals.
Audio models falter when sounds and listeners change
A preprint analysis finds target labels recover only part of the loss, while physiological and individual-level prediction remain much harder.
Distinct HLA-II patterns tied to Alzheimer’s and longevity
Preprint: Three inherited HLA-II haplotypes showed contrasting associations with Alzheimer’s disease, healthy centenarian status and microglial HLA-II load.
Thermal decay better explains Υ suppression in RHIC collisions
Preprint modeling of Au+Au collisions favors thermal decay over sudden color-screening loss in the studied RHIC data.
AI Unlearning Method Targets Identity Recall While Preserving Visual Answers
Preprint: An arXiv version 1 paper reports a two-stage method that uses forget images and probing questions at deletion time, without retain images or original fine-tuning VQA pairs.
HIBEAM tracking test finds a trade-off between precision and efficiency
Preprint: Simulated detector events show a trade-off between tighter vertices and higher reconstruction efficiency across classical and machine-learning methods.
AI model reconstructs liquid-metal flow from sparse sensors
A preprint reports fast estimates of temperature, pressure and velocity in simulated magnetic liquid-metal flows, with larger errors in some high-field cases.
Tokamak Pressure Models May Remove a Key Instability Transition
Preprint: Recomputing the magnetic equilibrium to match plasma pressure was linked to the disappearance of the usual ITG-to-KBM transition in the modeled cases.
AI chemistry system scores highest at recovering past ideas
A preprint describes an automated framework that retrieves literature and revises hypotheses, but its chemical ideas were not tested in the lab.
AlGaAs nanowires show unusually clean single-photon emission
An arXiv Preprint reports narrow emission lines and single-photon statistics from crystal-phase quantum dots inside the nanowires.
Primary ciliary dyskinesia study finds hidden social strain
Preprint: A questionnaire study found that many participants adapted routines, hid symptoms and reported limited support at work or school.
Health AI papers often omit how their agents are built and governed
Preprint: A framework scored 279 health-oriented AI-agent records and found evaluation details were more complete than architecture, governance and reproducibility.
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.
