Freight simulation reports less congestion but highest modeled total CO2 proxy
Preprint: A simulated freight corridor reported higher throughput and lower congestion for its Cognitive scenario, which also had the highest total CO2 emissions proxy.
Mathematical proof covers RNA targets with up to two short helices
Preprint: The result is limited to a simplified Watson-Crick model and does not test realistic thermodynamics or biological conditions.
Oscillator network reaches 100% on a two-vowel test
Preprint: A simulated formant-based network classified “ah” and “iy” perfectly, while a raw-waveform design scored 93% and broader tests showed limits.
Quantum Network Model Finds Pair of Tests for False Heralds
Preprint: The model pairs complementary measurements and reports higher modeled fidelity and delivery rates than matched all-BSM networks at specified operating points.
Five-Model Test Reports AI Tool-Call Rates Above 90%
Preprint: A training-free internal signal was associated with tool-call rates from near zero to above 90%, while live-search accuracy was higher at additional search cost.
MoPLEx reports higher scores and lower resource use in selected tests
Preprint: MoPLEx reports higher clustering and ranking scores on two benchmark datasets; resource reductions were limited to tested configurations.
GPU simulator reaches 2.03 million steps per second in tests
Preprint testing reports 2.03 million CartPole steps per second, while a deformable-object task reached 8.86 thousand and leveled off at about 512 environments.
Exact algorithms beat the 2^n search barrier in geometry
Preprint: A theoretical paper reports exact worst-case bounds below the 2^n exhaustive-search barrier for optimal discretization and point separation.
Preprint: Euclidean Prototypes Led on Accuracy, Hyperbolic on Local Recall
A study of about 81,446 paintings found a split: Euclidean prototypes classified styles better, while hyperbolic prototypes showed stronger local recall.
Type A Hessenberg Dimensions Hold Within Sheets When h Is Fixed
Preprint: With the Hessenberg function fixed, matrices in one sheet produce type A Hessenberg varieties with the same dimension.
Mathematicians identify when long-range networks recur
Preprint: New theorems set out sufficient conditions for recurrence in one- and two-dimensional random graph models, while phase boundaries remain open.
Preprint reports faster, more accurate water-wave simulations
A two-way model links a 2D wave calculation to a localized 3D fluid solver, with lower reported errors and faster runtimes in numerical tests.
Deep MEG data linked to stronger speech-decoding tests
Preprint: A 104.2-hour release combines deep recordings from one volunteer with broader data from 32 others.
Preprint reports smaller access-weighted proofs in Ethereum replay
ArXiv version 1 preprint: The report compares a tiered design with MPT and UBT in an Ethereum StateDB replay and controlled benchmarks.
PDE hedge may price some claims above the minimum
An arXiv preprint links the equation's minimum-capital result to an equivalent local martingale measure, while simulations show close tracking without one.
Study finds one intermediate can reduce waste in thermodynamic changes
Preprint: A mathematical model identifies unique intermediate states that reduce dissipated work and shows how reaction time can change an enzyme strategy.
TOI-4468 hosts a hot Jupiter and a nearby outer planet
Preprint: The system also shows an unconfirmed 624-day radial-velocity signal that may be an outer giant.
Cobalt ordering may explain antiferromagnetism near 250 K
Preprint findings link a 250 K antiferromagnetic transition to a calculated cobalt-rich layer and unusual electronic states.
Structured Graphs Get Quadratic-Time All-Pairs Shortest Paths
Preprint: Theoretical algorithms also give quadratic matrix products and near-linear searches for four- and five-vertex cliques in these graph classes.
