Theory maps Majorana signatures in short quantum-dot chains
An arXiv preprint uses idealized calculations to follow zero-energy modes as modeled chains grow from two to six quantum dots.
Preprint: Smaller Models Retain AUC of a Larger LHC Anomaly Detector
On simulated collisions, a boosted tree and a neural network stayed within 1% of the larger model’s AUC; FPGA timing is still a synthesis estimate.
Numerical ranges extended to multivalued Banach-space operators
An arXiv preprint sets out spectral enclosures and resolvent bounds, then illustrates the framework with an operator pencil and two semigroup examples.
Graph-Learning Method Shows Gains With Scarce Target Data
Preprint: The approach outperformed comparison methods in synthetic tests and a small multi-site fMRI analysis, but the human-data evidence remains preliminary.
Study gives exact recursive rules for binary phylogenetic trees
This preprint gives exact formulas for binary-tree covering numbers and a tight length bound for one sequence, while the ordinary covering number for general non-binary trees remains open.
Review Maps Potential Medical Uses for Microwave Kinetic Inductance Detectors
A technical review marked as a Preprint says microwave kinetic inductance detectors could bring low noise, spectral detail and larger arrays to four imaging fields, but reports no clinical testing.
Preprint claims every rational exponent α ≥ 1 can arise in graph counts
The asymptotic result uses fixed graphs, with the counted graph connected and of diameter at most 3; whether both graphs can be connected remains open.
One model could identify tracks and versions in benchmark tests
An arXiv preprint reports unified operation in a tested 10-second track-identification setting; scores varied between clean and altered audio and between segment durations.
New York audit flags gaps in predictive lead-line records
An arXiv preprint says New York City's model-cleared records showed no lead or Unknown entries, but the estimate is not a direct accuracy test.
Filesystem design catches every tested storage attack, but performance varies
Preprint: ShieldZFS detected all tested storage attacks, while performance losses varied by workload.
Study links singular q-Dirac spectra to scattering theory
A preprint develops a theorem-based framework for dissipative q-Dirac operators, with results on dilation, scattering, functional models and eigenvector completeness.
GPS receiver study links longer integration to lower frequency fluctuation
Preprint: Simulations and a one-satellite GPS test linked longer integration and reduced spacing with lower reported fluctuations, while filter behavior varied under dynamic conditions.
Model links warm ions to changes in the Moon’s surface sheath
A preprint model reports its strongest changes at higher lunar latitudes, with possible implications for dust charging and motion above the surface.
2D anisotropic fluid model obeys energy balance for weak solutions
Preprint: A mathematical proof also finds weak–strong uniqueness when one solution has extra vertical regularity and the initial data match.
Australian Soil-Water Model Performs Better in Western Regions
A preprint reports that SWEB matched observed soil-moisture patterns across most regions, but its proposed uses for yield estimation and fertiliser recommendations have not been tested.
Gaussian Model Outperforms Graph Model in Heart CT Shape Test
This preprint reports better shape completion than a graph-based comparator on aligned CT meshes, but expert-surface checks covered only part of the heart and did not establish clinical use.
Parallel web library shows big speedups but not everywhere
An arXiv preprint reports speedups of up to 414 times in tests, while some variants ran slower than the sequential baseline.
ShadowPath phone tests show a wide gap in credential proof times
Preprint: ShadowPath moves credential-specific status lookup to the holder; Groth16 proving took 2.93 to 3.11 seconds on two tested phones, while PLONK took 39.12 to 55.29 seconds.
Open-source speech models may favor benchmark text over audio
Preprint: Tests of 11 open-source ASR models found benchmark-linked output could persist when speech was masked, altered or replaced.
