A flow approach to the Toda system
In this paper we introduce a flow to study the Toda system, which we call {\it Toda flow.} More generally, we introduce a flow of the Liouville systems, formulated as a coupled parabolic system wit...

Reduced-order computational homogenization for hyperelastic media using gradient based sensitivity analysis of microstructures
We propose an algorithm for the computational homogenization of locally periodic hyperelastic structures undergoing large deformations due to external quasi-static loading. The algorithm performs c...

Formation of first star clusters under the supersonic gas flow -- III. Environmental trends and halo-to-halo scatter in the Pop III IMF
The first generations of stars ionised and enriched their host galaxies and seeded the growth of massive black holes. Models often assume that Pop III stellar masses in different minihaloes are sto...

MatchED: Crisp Edge Detection Using End-to-End, Matching-based Supervision
Generating crisp, i.e., one-pixel-wide, edge maps remains one of the fundamental challenges in edge detection, affecting both traditional and learning-based methods. To obtain crisp edges, most exi...

A Low Cost Picoseconds Precision Timing and Synchronization Over A Hundred Kilometer
Large-scale systems, such as very large accelerators used for fundamental research, require the implementation of precise timing and synchronization systems over distances of several tens of kilome...

Correlator-Level Verification of Mass and Current Maps in Abelian Chern-Simons Dualities
We construct an explicit local operator realization that reproduces Dirac fermion correlation functions in three spacetime dimensions within an Abelian Chern-Simons framework and use it to examine ...

A Case Study on Runtime Verification of a Continuous Deployment Process
We report our experience in applying runtime monitoring to a FluxCD-based continuous deployment (CD) process. Our target system consists of GitHub Actions, GitHub Container Registry (GHCR), FluxCD,...

GATES: Self-Distillation under Privileged Context with Consensus Gating
We study self-distillation in settings where supervision is unreliable: there are no ground truth labels, verifiable rewards, or external graders to evaluate answers. We focus on document-grounded ...

Range Emulator: A Compact Paraxial Optical System to Emulate Long-Distance Monochromatic Laser Propagation
Emulating long-distance light propagation on a laboratory scale is essential for the ground-based testing of intersatellite optical systems. To address this challenge, we propose and analyze a nove...

Probing and Bridging Geometry-Interaction Cues for Affordance Reasoning in Vision Foundation Models
What does it mean for a visual system to truly understand affordance? We argue that this understanding hinges on two complementary capacities: geometric perception, which identifies the structural ...

Fast Algorithms for Exact Confidence Intervals in Randomized Experiments with Binary Outcomes
We construct exact confidence intervals for the average treatment effect in randomized experiments with binary outcomes using sequences of randomization tests. Our approach does not rely on large-s...

Evolution of Spatial Complexity in Flare Ribbon Substructure and Its Relationship to Magnetic Reconnection Dynamics
Recent three-dimensional flare models suggest that flare-ribbon substructure is linked to the fragmentation of the reconnecting current sheet in the corona. Flare-ribbon substructure can therefore ...

A Long-Short Flow-Map Perspective for Drifting Models
This paper provides a reinterpretation of the Drifting Model~\cite{deng2026generative} through a semigroup-consistent long-short flow-map factorization. We show that a global transport process can ...

A Unified Error Correction Code for Universal Quantum Computing with Identical Particles
We present a universal fault-tolerant quantum computing architecture based on identical particle qubits (IPQs), where we find that the first-order IPQ - bath interaction fundamentally differs from ...
