Preprint links legal-school filtering to better Arabic Islamic-law search
In a 503-question benchmark, filtering by school was associated with the largest reported gains on school-specific questions; generated-answer quality was not tested.

Preprint finds a boundary mass as diffusion vanishes in moving models
A one-dimensional mathematical analysis derives a dynamic boundary law and suggests competing stable states, while leaving broader cases unresolved.
Preprint maps when layered spheres are predicted to resonate
Idealized acoustic calculations link resonance regions to shell thickness and impedance contrasts, while identifying a high-impedance region that remains non-resonant.
Preprint finds quantum ‘jamming’ is either trivial or permits hidden signaling
A mathematical analysis says the proposed extension either reduces to ordinary quantum behavior or conflicts with no-superluminal signaling.
Preprint: A Wider Quantum Circuit Can Shorten Spin-Simulation Runs
A computer study found that redundant qubit registers reduced modeled circuit depth and improved noisy spectral signals in some cases, but the circuits were not run on hardware.
Preprint reports sub-sample timing accuracy in simulated high-mobility OTFS link
The proposed pipeline also stayed within less than 2 dB of a perfect-CSI reference, but the study tested a modeled single-user system rather than physical hardware.
Preprint explains when random particle systems follow fluid laws
The mathematical notes link large-scale density averages to deterministic equations, while showing that fluctuation scales depend on the model and dimension.
Preprint reports lower prediction errors from a two-stage neural-network method
The approach learns a shared pattern from pooled data before modeling each group’s differences, with favorable results in simulations and two real-data tests.
Preprint narrows where sphere-valued maps can become singular
A mathematical analysis gives sharp dimension limits and shows that some stable tangent maps must be constant.
Preprint reports faster classification-tree training with a smaller split search
DICS recorded large reported speedups on synthetic and benchmark tests, while accuracy remained comparable in some comparisons and fell in others; regression was not evaluated.
Preprint outlines exact quaternionic quantum operations, but no unique octonionic continuation
A formal study represents quaternionic states, channels and error correction in constrained complex spaces while comparing octonionic frameworks that preserve different operational structures.
Preprint says round disk is hardest convex shape to map onto a plane
A geometric proof says equal-area convex regions on a sphere can be mapped to the plane within the round disk’s distortion benchmark.
Preprint argues Spatial AI should work with spatial statistics
The conceptual review says spatial scale, dependence, sampling design and uncertainty must remain central as models become more flexible.
Preprint finds finite high-order Drude weights where theory predicted divergence
Exact Bethe-ansatz calculations in a one-dimensional Hubbard model challenge a low-energy prediction at quarter filling, while half-filled odd-order weights show exponential finite-size suppression.
Preprint builds a chain in which both π2 maps are zero
The formal construction links three two-complexes, while a separate Lie-ring example shows a nonzero identity among relations in the smaller presentation.
Preprint: Targeted Vibrations Linked to Different Proton-Transfer Outcomes
Computer simulations of two fluorophore models found ultrafast single- and double-proton transfer under selected vibrational conditions, while room-temperature baseline runs showed little transfer.
Preprint finds a second critical boundary in a model of learning from measurements
Calculations and finite-size simulations point to a three-phase meeting point, with a possible connection to toric-code error correction.
Preprint reports stronger jump-control results with active suspension
In selected simulations, a combined controller passed a post-landing attitude test in all 24 boundary runs, but the findings remain tied to specific ramps, speeds and a modeled vehicle.
Preprint tests a neural-network method for shaping 3D light patterns
In simulations and fluorescent-bead experiments, the approach reproduced several designed point-spread functions and used fewer reported iterations than pixel-based methods in one benchmark.
Preprint Reports Higher Simulated Secrecy Rates With a Movable Drone-Mounted Reflector
A mathematical model reported higher rates when the reflector’s position, orientation and reflection settings were optimized together, but hardware and field performance remain untested.
