packet_delays: Internet packet delays (2002)
A network representing the difference in delay observed by packet probes sent from a computer at Rice University to similar machines at different universities, in c.2002. The edge weight denotes the difference in delay of the packet in milliseconds.
This network has 10 nodes and 9567 edges.

A stability-enhanced nonstandard finite difference framework for solving one and two-dimensional nonlocal differential equations
Standard finite difference (SFD) schemes often suffer from limited stability regions, especially when applied in explicit setup to partial differential equations. To address this challenge, this study investigates the efficacy of nonstandard finite difference (NSFD) schemes in enhancing stability of explicit SFD schemes for 1D and 2D Caputo-type time-fractional diffusion equations (TFDEs). A nonstandard L1approximation is proposed for the Caputo fractional derivative, and its local truncation e…

PROD: Palpative Reconstruction of Deformable Objects through Elastostatic Signed Distance Functions
We introduce PROD (Palpative Reconstruction of Deformables), a novel method for reconstructing the shape and mechanical properties of deformable objects using elastostatic signed distance functions (SDFs). Unlike traditional approaches that rely on purely geometric or visual data, PROD integrates palpative interaction -- measured through force-controlled surface probing -- to estimate both the static and dynamic response of soft materials. We model the deformation of an object as an elastostati…

TDRM: Smooth Reward Models with Temporal Difference for LLM RL and Inference
Reward models are central to both reinforcement learning (RL) with language models and inference-time verification. However, existing reward models often lack temporal consistency, leading to ineffective policy updates and unstable RL training. We introduce TDRM, a method for learning smoother and more reliable reward models by minimizing temporal differences during training. This temporal-difference (TD) regularization produces smooth rewards and improves alignment with long-term objectives. I…

Kann bitte der Gesetzesbrecher #Dobrindt zurücktreten. Gerade wer sein Ministeramt so unverhohlen und notorisch missbraucht, um Gesetze zu brechen, sollte keine Mitsprache bei der Besetzung von Richterämtern bekommen.

FractMorph: A Fractional Fourier-Based Multi-Domain Transformer for Deformable Image Registration
Deformable image registration (DIR) is a crucial and challenging technique for aligning anatomical structures in medical images and is widely applied in diverse clinical applications. However, existing approaches often struggle to capture fine-grained local deformations and large-scale global deformations simultaneously within a unified framework. We present FractMorph, a novel 3D dual-parallel transformer-based architecture that enhances cross-image feature matching through multi-domain fracti…

What makes a study design quasi-experimental? The case of difference-in-differences
Study designs classified as quasi- or natural experiments are typically accorded more face validity than observational study designs more broadly. However, there is ambiguity in the literature about what qualifies as a quasi-experiment. Here, we attempt to resolve this ambiguity by distinguishing two different ways of defining this term. One definition is based on identifying assumptions being uncontroversial, and the other is based on the ability to account for unobserved sources of confoundin…
