The Anatomy of the Column Density Probability Distribution Function

We dissect the N-PDF of molecular clouds into lognormal and power-law regimes, tracing each to distinct physical processes.

Turbulent Cascades in Weakly Ionized Interstellar Media

Ambipolar diffusion truncates the cascade below the decoupling scale, steepening spectra beyond classical predictions.

On the Convergence of Stochastic Interpolants

We give non-asymptotic bounds for interpolant flows under mild moment conditions on the coupling.

A Spectral Approach to Cross-Lingual Alignment

Eigenvector coherence across monolingual graphs yields alignments competitive with supervised baselines.

Magnetic Field Morphology in Filamentary Clouds

Polarization angles turn perpendicular to filament spines above a critical column density threshold.

Low-Rank Adaptation Under Distribution Shift

Rank-constrained updates preserve calibration under covariate shift where full fine-tuning degrades.

Sparse Recovery with Correlated Design Matrices

Restricted eigenvalue conditions are relaxed via a peeling argument on correlated blocks.

Kinematics of Infalling Envelopes Around Class 0 Protostars

Line asymmetries constrain infall rates to a few 10⁻⁶ solar masses per year across the sample.

Measure Transport for Rare-Event Simulation

A normalizing-flow proposal reduces estimator variance by two orders of magnitude in tail regimes.

Neural Machine Translation of Mathematical Prose

Notation-aware tokenization halves symbol corruption while preserving theorem-proof structure.

Dust Opacity Variations in Prestellar Cores

Grain growth flattens the opacity index toward core centers, biasing mass estimates by up to 40%.

Implicit Regularization of Momentum Methods

Heavy-ball trajectories track a modified flow whose potential penalizes sharp minima.

A Census of High-Velocity Clouds in the Galactic Halo

Absorption-line distances place most complexes within 15 kpc, favoring a fountain origin.

Terminology Drift in Long-Horizon Scientific Corpora

Diachronic embeddings reveal systematic semantic drift in physics terminology across five decades.

Bayesian Deconvolution of Blended Emission Lines

Hierarchical priors on line widths resolve blends at half the signal-to-noise of standard fits.
