Direct fixed-weight solver for free-support Wasserstein medians relocates atoms using OT barycentric projections and inverse-distance weights, achieving monotone descent on smoothed objectives with fewer subproblems than nested Weiszfeld baselines.

J-LAW introduces a coupled latent factor graph that jointly optimizes metric poses, latent states, and landmark embeddings to produce maps that are both metric and actionable for planning.
Drift-React produces full minimum energy pathways for reactions in a single step via SE(3) drifting fields, matching TS accuracy of iterative models with orders-of-magnitude speedup on Transition1x and Halo8 datasets.
A stereo calibration framework for RGB-TIR cameras with 625:1 resolution asymmetry uses an active OLED screen, Hessian-based corner detection, and baseline-constrained bundle adjustment to achieve 0.382 px reprojection error.
In low-extinction galactic open clusters fast and slow rotators populate distinct parts of the extended main-sequence turnoff while differential extinction inflates the turnoff width and biases age estimates in others.
Introduces and proves stability for a persistent homology-based bi-conditional periodicity score for pairwise time series similarity.
A review reframing density estimation as 'density evolution' across scales, linking kernel smoothing to heat flow, mixtures to compression, and topology to level sets, while stating three structural results on modes, Gaussian semigroups, and log-concavity.
PCA analysis of NANOGrav data recovers known pulse shape changes tied to timing events in pulsars like J1713+0747 and identifies new candidates and a recurrence in PSR B1937+21.

Density Evolution: A Multiscale View of Density Estimation
A review reframing density estimation as 'density evolution' across scales, linking kernel smoothing to heat flow, mixtures to compression, and topology to level sets, while stating three structural results on modes, Gaussian semigroups, and log-concavity.
