Feasibility of Radio Frequency Based Wireless Sensing of Lead Contamination in Soil

arXiv:2512.16071v1 Announce Type: new
Abstract: Widespread Pb (lead) contamination of urban soil significantly impacts food safety and public health and hinders city greening efforts. However, most existing technologies for measuring Pb are labor-intensive and costly. In this study, we propose Soil…

Feedback stabilization of some fourth-order nonlinear parabolic equations with saturated controls

arXiv:2512.05606v2 Announce Type: replace
Abstract: In this work, we analyze the internal and boundary stabilization of the Cahn-Hilliard and Kuramoto-Sivashinsky equations under saturated feedback control. We conduct our study through the spectral analysis of the associated linear operator. We ide…

UniDepthV2: Universal Monocular Metric Depth Estimation Made Simpler

arXiv:2502.20110v2 Announce Type: replace
Abstract: Accurate monocular metric depth estimation (MMDE) is crucial to solving downstream tasks in 3D perception and modeling. However, the remarkable accuracy of recent MMDE methods is confined to their training domains. These methods fail to generalize…

Tight Analysis of a One-Shot Quantum Secret Sharing Scheme

arXiv:2511.04399v2 Announce Type: replace-cross
Abstract: Quantum communication protocols can be designed to detect eavesdropping attacks, something that classical technologies are unable to do since classical information can be replicated in a non-destructive manner. Eavesdropping detection is, th…

On The Hidden Biases of Flow Matching Samplers

arXiv:2512.16768v1 Announce Type: cross
Abstract: We study the implicit bias of flow matching (FM) samplers via the lens of empirical flow matching. Although population FM may produce gradient-field velocities resembling optimal transport (OT), we show that the empirical FM minimizer is almost neve…
