Factored Levenberg-Marquardt for Diffeomorphic Image Registration: An efficient optimizer for FireANTs
FireANTs introduced a novel Eulerian descent method for plug-and-play behavior with arbitrary optimizers adapted for diffeomorphic image registration as a test-time optimization problem, with a GPU...

AURORA: Adaptive Unified Representation for Robust Ultrasound Analysis
Ultrasound images vary widely across scanners, operators, and anatomical targets, which often causes models trained in one setting to generalize poorly to new hospitals and clinical conditions. The...

Survival of the most compact: the life and death of satellite halos in self-interacting dark matter
Self-interacting dark matter (SIDM) models feature short-range interactions between dark matter (DM) particles that lead to larger diversity in the inner parts of galactic rotation curves and poten...

Towards a Refinement of Krylov Complexity: Scrambling, Classical Operator Growth and Replicas
We propose and test logarithmic Krylov (logK) complexity, an operator growth measure akin to Krylov complexity defined through a replica approach, as a viable probe of early-time operator scramblin...

Toward universal coalescence models for antideuteron production
Cosmic-ray (CR) antinuclei, especially antideuteron $\overline{\rm D}$ and antihelium-3 nuclei ${}^3\overline{\rm He}$, are among the most promising messengers for indirect dark matter (DM) searche...

$S^3$ partition functions and Equivariant CY$_4 $/ CY$_3$ correspondence from Quantum curves
We study the perturbative large-$N$ expansion of the round three-sphere partition function in a class of M2-brane theories, including flavored SYM and ABJM theories as well as more general 3d theor...

Spectral reconstruction techniques, their shortcomings and relevance to the electric conductivity coefficient
Spectral reconstruction is a well studied numerically ill-posed problem which arises due to the relation of the Euclidean correlator to the spectral function via an inhomogeneous Fredholm equation ...

Performance Testing of ChaCha20-Poly1305 for Internet of Things and Industrial Control System devices
Industrial Control Systems (ICS), and many simple Internet of Things (IoT) devices, commonly communicate using unencrypted or unauthenticated protocols. For ICS this is an historical carryover sinc...

Anatomical Heterogeneity in Transformer Language Models
Current transformer language models are trained with uniform computational budgets across all layers, implicitly assuming layer homogeneity. We challenge this assumption through empirical analysis ...

Multi-Modal Building Change Detection for Large-Scale Small Changes: Benchmark and Baseline
Change detection in optical remote sensing imagery is susceptible to illumination fluctuations, seasonal changes, and variations in surface land-cover materials. Relying solely on RGB imagery often...

A conservative, discontinuous Galerkin, tracer transport scheme using compatible finite elements
This paper outlines a conservative transport scheme for scalar tracers within a compatible finite element model for geophysical fluid equations. Instead of using the advective transport equation fo...

CAMO: A Conditional Neural Solver for the Multi-objective Multiple Traveling Salesman Problem
Robotic systems often require a team of robots to collectively visit multiple targets while optimizing competing objectives, such as total travel cost and makespan. This setting can be formulated a...

Fair Decoder Baselines and Rigorous Finite-Size Scaling for Bivariate Bicycle Codes on the Quantum Erasure Channel
Fair threshold estimation for bivariate bicycle (BB) codes on the quantum erasure channel runs into two recurring problems: decoder-baseline unfairness and the conflation of finite-size pseudo-thre...

Hardness of High-Dimensional Linear Classification
We establish new exponential in dimension lower bounds for the Maximum Halfspace Discrepancy problem, which models linear classification. Both are fundamental problems in computational geometry and...

Optimal Sample Size Calculation in Cost-Effectiveness Longitudinal Cluster Randomized Trials
Longitudinal cluster randomized trials (L-CRTs) are increasingly used to evaluate the cost-effectiveness of healthcare interventions across multiple assessment periods, yet design methods for power...

Non-Markovian Cosmic-Ray Pitch-Angle Transport from Mirror Interactions
Cosmic-ray pitch-angle transport in magnetohydrodynamic (MHD) turbulence is governed by the interplay between magnetic mirroring and gyroresonant scattering. We develop a guiding-center (GC) Langev...
