New graph theorem maps missing links that complete forbidden cliques
Preprint: The result covers the full Turán edge range and gives an exact formula for the triangle case.
Robot-planning method balances lower path costs and route diversity
Preprint: The method was tested in robot-manipulation benchmarks and street-view map searches.
Preprint tests diffusion models for finer daily precipitation maps
The study compares three conditioning strategies using ERA5 atmospheric inputs and ERA5-Land precipitation targets in the Colorado River Basin.
Preprint maps a kinetic fluid model exactly into Fock space
The mathematical construction keeps physical moments and coordinate invariance intact while deriving model-based viscosity and heat transport.
SlimTCP was fast in tests, but simplicity may not be why
Preprint: SlimTCP led at larger segment sizes in controlled data-centre tests, but the authors say the role of simplicity remains unclear.
AI Weather Models Forecast Well but Miss the Butterfly Effect
A preprint under review finds stronger large-scale skill alongside less realistic growth of small errors.
Hot QCD theory maps a full imaginary turn to the Roberge-Weiss point
Preprint: Exact operator identities connect a full imaginary turn to the Roberge-Weiss point, while an on-axis one-loop calculation predicts a continuous C-breaking onset and a separate first-order lock-in.
KIT4 study reports more coherent TV localization; final pair unresolved
Preprint: A visual comparison of four penalties on measured KIT4 tank data found more coherent localization with smoothed TV and Huber-TV, while the final difficult two-inclusion configuration was not resolved.
A detector-sharing method broadens coverage while retaining expertise
Preprint: In an MS COCO 2017 benchmark, the method reported higher final coverage scores while original-category performance stayed close to starting values.
Cosmic-Web Sub-Filaments Differ From Parent Filaments
Preprint simulations suggest that cosmic-web sub-filaments differ from parent filaments in density, inflow and motion after matching node mass and relative radius.
Model predicts stark gap between two charm-strange radiative widths
Preprint analysis covers four heavy-strange transitions, with sharply different charm-strange predictions and comparable bottom-strange estimates.
AI model generates patient-matched hip implant shapes from CT
An arXiv preprint reports technical feasibility in a retrospective single-centre cohort, while clinical benefit was not tested.
Preprint tests a way to sample constrained states without leaving them
A geometry-aware diffusion method matched analytical targets in simulations, but its practical approximations still lack convergence guarantees.
Smaller Conflicts May Be Tied to Higher AI-era Catastrophic Risk
A qualitative arXiv preprint assesses war, terrorism and AI-control pathways, but does not calculate how the risks compare.
AI explainer recovers more literature-backed clues from drug-pair scores
Preprint: A computational test found that VINCENT recovered more annotated molecular regions and tracked the fixed predictor's synergy output more closely than tested baselines.
Sulfur spectra resemble valence spectra while fluorine shows extra features
Preprint: Measurements show sulfur spectra resembling valence spectra after resolution differences are considered, while the model underestimates high-energy fluorine intensity.
Model suggests a new route to tunable light-hole qubits
A preprint reports modeled light-hole qubits with stronger spin response and a bilayer that switches between heavy-hole and light-hole character.
OFDM preprint finds compact model handles amplifier distortion
Preprint: Simulations recovered nonlinear channel behavior at low signal-to-noise levels and supported compensation close to an ideal linear system.
Human reviewers favor a rebuilt benchmark for key-point analysis
An arXiv preprint reports that human reviewers preferred re-annotated structures for grouping, key-point quality and coverage over structures derived from ArgKP21.
