Molecular rotation may matter more than bending in CO2 reaction
This preprint reports simulations suggesting that rotational motion may influence carbon dioxide reactivity on copper more strongly than bending vibration.
Preprint: Polymer-filled pores could speed selective particle transport
A theoretical model predicts lower resistance and sharp filtering by particle size and surface affinity.
Graph method reconstructs 158 molecular energy levels from spectra
Preprint: A graph-based analysis reconstructed HDO energy levels without a model or prior assignments, but 261 measured transitions remained outside the network.
Orbital graph model predicts electron correlation across three tests
Preprint: The model reported low errors on nitrogen dissociation, 18 diatomic species and five octahedral iron(II) complexes.
Jellyfish study links bacteria and arginine to arm regrowth
A peer-reviewed laboratory study found that feeding, penicillin and arginine were associated with regeneration in young moon jellyfish, while the proposed mechanism remains untested.
Mental-health symptoms varied sharply across Chongqing industries
A survey of 10,112 front-line workers found industry-specific differences, while pain, stress and long hours were linked to combined symptoms.
Parents of children with SEND report gaps in mental-health support
A study in and around York found that 68% of survey respondents called support insufficient and 75% rated availability poor or very poor.
Diatom structures show a shared pattern of spatial order
Preprint analysis of two-dimensional SEM images found a common statistical pattern across 21 marine diatom genera, but did not test its cause or function.
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.
