A training-free defense that embeds a compressed representation of clean speech into the signal showed much lower error rates than tested passive systems when one or two words were swapped, while very short edits remained harder to detect.
A preprint reports lower Mandarin homophone error rates and higher synthetic HumourPhone recall with a task-conditioned adapter, while the study’s humour test was small and had no human evaluation.
A model fitted against preliminary ALICE measurements predicts that the maximum charged-hadron production in p-O collisions moves from the oxygen-going side in central events toward the proton-going side in peripheral ones, but final data are needed to test the result.
A theoretical preprint predicts that a one-dimensional disordered model can retain a sharp zero-momentum peak while its wave function spreads through algebraic tails.
A mathematical study reports finite-dimensional quantum channels whose two-copy minimum output entropy eventually falls below twice the one-copy value, while leaving the related classical-capacity question open.
A theoretical preprint presents a way to turn impedance and admittance responses into exact Hamiltonians and controlled reduced models for superconducting circuits. Its examples cover discrete filters, finite-band metamaterials, nonreciprocal waveguides and giant atoms, while stressing that the reductions depend on their approximation regimes.
A computational study uses variational autoregressive networks to examine how activity, density and response change in simple exclusion models, finding benchmark agreement and a possible inverse-square scaling pattern.
A theoretical magnetic-lattice study derives the model's four energy bands, eigenstates and quantum geometry in closed form, then finds the lowest band nearly ideal by an integrated test but not perfectly flat.
A laboratory capsule combined a soft cover, a payload-carrying base and a magnetically heated gel latch to release representative microrobots on a printed platform and ex vivo porcine stomach tissue. The demonstrations do not establish performance inside a living gastrointestinal system.
SENSE combines electrode-geometry encoding with semantic conditioning and ranked first across the study's main EEG-to-speech tests, but the authors say reliable word-level reconstruction remains difficult.
A study of thousands of quasars found that repeated X-ray observations reveal a weak positive association between spectral shape and accretion state, but the signal is too small to explain most of the observed variety.
A small Subaru study identifies one CEMP-s star with the highest magnesium-to-iron ratio reported for a turn-off star of its kind, while its binary origin and Galactic membership remain unresolved.
A laboratory experiment stored burst-mode laser energy in an optical enhancement cavity and found that carrier-envelope offset control becomes increasingly important as finesse rises.
A preprint study found that disagreement between a fast decoder and its syndrome-consistent correction can identify shots likely to fail, focusing deeper computation where it helped most in simulation.
A preprint based on numerical simulations reports shorter transfer times for STIRSAP than for conventional STIRAP in a four-level calcium-ion model. The result is based on parameter sweeps and a simulated loss model, not a laboratory demonstration.

An X-ray analysis of NGC 3079 reports a 0.92-million-year nuclear superbubble and a modeled 29.6-million-year galactic-scale bubble, while placing the inferred supernova progenitor cutoff at about 13 to 15 solar masses under a pure core-collapse model.
A scalar-QED model reports a lower bound-state decay rate than the free rate, while the leading Coulomb distortion of the outgoing charged-pion wavefunction first appears at fourth order.
A preprint models X(2370) as a state generated by the interaction of phi with h1(1380), treating h1(1380) as a K* Kbar molecule. Its calculated mass, width and decay pattern are presented as consistent with the assignment, while additional mass structures remain unreported predictions.
A theoretical study finds that changing drift reshapes the model's lowest energy level and predicts how rare joint fluctuations and open-time/current sensitivity behave.
A preprint describes recursive quantum-code constructions that increase code distance and certify circuit-level protection, while simulations show steeper suppression under a specified setup.
A preprint presents PDBQITE as a shallower alternative to recursive DB-QITE, with reported gains in molecular and graph simulations but an exponentially declining chance of completing many postselected steps.
A superconducting quantum thermal machine recorded a TUR ratio below the classical benchmark at 81 mK, while the result remains a preprint and relies on inferred photon fluctuations and model comparisons.
A fully coupled holographic simulation of two-dimensional quantum turbulence reports unusual normal-fluid velocity statistics and a temperature-linked decline in fluctuations, even as vortex density increases.
A laboratory preprint reports a 14-fold extension in the tested lower limit for oxygen-isotope fractions, while matching a linear reference across nominal tungsten-oxide markers.
An exact theoretical study of a symmetric double-Morse oscillator distinguishes changes in the modeled ground state from changes caused by how the same quantum state is represented.

A laboratory study used spatially resolved multispeckle light scattering to compare equilibrium and metastable colloidal fluids, finding that the latter developed heterogeneous dynamics as crystallization approached.
A new numerical method reports lower velocity-space workloads in gas-flow tests while preserving key fields and conservation measures, but its gains remain tied to the tested implementation.
The proposed method transfers polynomial quantum states between source and target systems by relative decoding, but its benchmark result remains a limited comparison.
A model-based preprint finds a very small allowed region for twin-star scenarios, while two modeled neutron-star masses have nearly equal median radii.
A model fitted to DESI Full-Shape measurements finds a modest increase in the inferred matter-density parameter with redshift. Current tests do not clearly prefer that trend over a constant value, and the dark-energy interpretation remains model-dependent.
