Preprint sharpens Carlson's inequality with a distance measure
A mathematical analysis adds a best-possible remainder term and extends the same variational approach to infinite sequences and finite sums.
Preprint Sets Out Faster Ways to Group Probabilities
A mathematical study presents one exact but exponential method and two faster approximation algorithms for merging consecutive probability values under an entropy cap.
Quantum sensing preprint finds an optimum for repeated photon passes
A model finds the most information per absorbed photon at a specific loss level, while adaptive sensing remains outside the fixed-scheme result.
Computer models find rare black hole mergers in stellar triples
Preprint: A model of 52,464 massive triples finds stable and unstable merger pathways, with a small high-eccentricity tail at 10 Hz.
Preprint reports steadier solvers in 3D tumor-growth models
A numerical study tested Schur-complement preconditioners across two diffuse-interface tumor-growth models in two and three dimensions, with AMG requiring fewer iterations than ILU in one 3D comparison.
Compact plant-health model keeps its accuracy after quantisation
This preprint reports that a compact plant-health model matched its float version's accuracy after packaging, but class-balanced performance dipped, especially in fruit categories.
Model links defects to long-lived light states in 3D crystals
Preprint calculations report a localized mode inside a modeled band gap, with decay falling sharply as the crystal grows, but no experiment is reported.
TP-MPPO Simulation Reports Higher Goodput for Edge LLMs
Preprint: In a synthetic wireless-edge system, the method outperformed four benchmarks on reward and requests meeting end-to-end latency targets.
Laser cavity reaches one watt of deep-ultraviolet light near 230 nm
Preprint: Researchers report a high-power continuous-wave source, but say coating lifetime remains a central challenge.
NGC 4438 study finds energy estimates shift with scale
Preprint analysis compares two compact bubbles with a larger outflow, finding different energy balances and a sharp mismatch between radio-based and resolved power estimates.
Quantum decoder matches exact results but slows on larger codes
A preprint reports near-exact decisions in simulations, while larger-code tests and hardware pilots expose runtime and model limits.
Protein AI Models Contain Biochemical Signals Tied to Fitness
Preprint: Removing biochemical patterns from protein embeddings lowered classifier performance, while randomized projections had little effect.
Hybrid Method Reports Higher MapReduce Throughput in Simulation
Preprint: DDPG-CVX outperformed five allocation methods in a five-device MapReduce model, with the largest gap against MAXF.
SGD study finds adaptive bounds can justify earlier stopping
Preprint: A confidence-sequence method follows the observed SGD trajectory and is designed to certify target accuracy without a fixed horizon.
Preprint links seven usability factors to shopping app ratings
An analysis of five shopping applications used in Pakistan reports a strong in-sample model, but leaves questions about how widely it applies.
Finite test identifies when toric blow-ups need no extra generators
This preprint reports algebraic criteria that reduce an infinite saturation problem to finite checks and gives exact results for several toric spaces.
Solar 'Fishbone' Structure Shows 18 Repeated Brightenings
Preprint: A 2015 solar active region showed 18 recurrent brightenings and moving plasma, but the data do not show that one reconnection site triggered the next.
Seven vision-language models struggle when first-person video and dialogue disagree
Preprint: A benchmark of seven vision-language models found low accuracy when first-person video and dialogue conflicted, along with wide variation in when models chose to intervene.
Sparse PINN tests find no single best pruning rule
An arXiv preprint reports lower Gray–Scott residuals for PI-SAP, while accuracy rankings shift with sparsity, width and equation.
