Preprint proposes a model for visco-elastic phase boundaries
The mathematical analysis gives the system a gradient-flow structure and establishes weak varifold-solution existence, with BV solutions only under additional conditions.

Preprint reports AI skill selector reaching 0.73 benchmark success with fewer tokens
Best Prefix Selection scored bundles of skills for a language-model agent, but the evidence comes from one frozen-executor benchmark.
Preprint extends Bayes’ rule to infinite-dimensional mathematics
The Petz recovery map meets the proposed rules for reversing mathematical transformations, but its uniqueness remains an unproved conjecture.
Preprint review finds diverse neural dynamics but concentrated learning rules
An audit of 32 architecture–learning configurations found every forward-dynamics class represented, while global-gradient methods accounted for 16 entries.
Preprint links partial permutations to ‘forgotten’ symmetric functions
A symbolic framework turns class-function evaluations into algebraic and combinatorial formulas, including a two-row rule for a set-mapping element.
Preprint model says changing pore networks can steepen stiffness scaling
An analytical framework separates local strut mechanics from changes in connectivity, backbone participation and load-path efficiency.
Preprint finds a recurrence property survives every finite colouring
A mathematical proof shows that when a set with “nice recurrence” is divided into finitely many colour classes, at least one class retains the same property.
Preprint: Simulations link weak dissipation to dominant solitons in shallow-water waves
Random-wave backgrounds were associated with long-lived modeled structures, but the result does not establish real-world rogue-wave risk.
Preprint reports a 260-fold speedup for simulated active-IRS beamforming
In synthetic blocked-link simulations, a rate-profile learning approach had a higher reported sum rate than WMMSE, but the result has not been tested on hardware.
Preprint finds dense graphs have no nonsynchronized Kuramoto energy minima
A mathematical proof says that, for some unspecified positive η, every finite simple graph with minimum degree at least (3/4 − η)n has fully synchronized states as its only local energy minima.
Preprint: Time-series model posts stronger forecasts with fewer parameters
SATS reported leading scores on zero-shot and in-distribution tests, but the analysis did not include confidence intervals or repeated runs.
Preprint proves a degree threshold guarantees disjoint cycles of different lengths
The abstract theorem applies to finite simple directed graphs and extends to weighted cycles, but it does not provide the smallest or an optimized threshold.
Preprint reports wide-field infrared imaging without direct infrared detection
A benchtop experiment used visible interference and a CMOS camera to reconstruct images while an infrared beam passed through a test mask.
Preprint finds preference tuning can push flow-based image models off their data manifold
ThermoDPO-weighted improved reported toy and image-generation scores, but the evidence comes from offline benchmarks and a one-author human evaluation.
Preprint Finds a Greedy String Algorithm Can Approach Twice the Best Possible Length
Specially constructed fixed-length inputs establish a worst-case lower bound of 2 for strings of length six or more, while the exact ratio for three-character inputs is 9/5.
Preprint: Simulation reports abrupt cooperation collapse as defection becomes more tempting
A lattice-based model links reputation-weighted learning with sharp shifts, competing outcomes and the growth or extinction of cooperative clusters.
Preprint Reports Gains From Randomized Reservoir Ensembles in Chaotic-System Tests
Hénon and Lorenz 96 tests showed useful ensemble forecasts, while a folded-towel-map result focused on forecast geometry.
Preprint reports spin-torque signal in largely disordered YPtBi films
The response persisted through 400 °C, while chemical mixing at the upper interface emerged as a stronger clue than bulk crystallization.
Preprint reports stronger simultaneous approximations for selected number pairs
The proof-based study constructs common denominators and reaches classical and p-adic Littlewood conclusions only under stated mathematical conditions.
Preprint links faster changes in stock co-movement to a volatility premium
A monthly S&P 500 analysis found the association in implied variance before broader realized volatility, but found no timing advantage or crash protection.
