A Nonlocal $p$-Laplacian Interface Model with Sharp Interface
Announce Type: cross Abstract: We propose an energy-based nonlocal $p$-Laplacian interface problem. Neumann interface conditions are naturally formulated via the energy, while Dirichlet conditions are enforced through a penalty term. A key feature is that the model retains a sharp interface, which facilitates extension to other interface problems; we illustrate this by developing a nonlocal approximation for the $p$-Laplacian interface problem with membrane conditions.
Resonance-induced frequency splitting and evanescent modes at temporal interfaces in elastic metamaterials
Announce Type: new Abstract: Temporal interfaces, defined by abrupt changes in material properties, break temporal translational symmetry and enable wave phenomena fundamentally different from those at spatial interfaces. Unlike spatial scattering, temporal scattering preserves momentum rather than energy, leading to instantaneous frequency shifts governed by the dispersion relations on either side of the interface. Existing studies in elastic media have mainly considered non-resonant...
The Immersed Discontinuous Galerkin Method for Elliptic Interface Problems
arXiv:2606.01814v1 Announce Type: new Abstract: This paper is devoted to construction and convergence analysis of the linear explicit immersed finite element (IFE) function. For the interface elements, the proposed IFE functions precisely satisfy the interface conditions on the actual interface. The IFE functions are constructed in an explicit form and can be obtained directly without solving any auxiliary problems or local linear systems.
Analytic patch trees: branch interface inheritance and fractal dimension fields
Announce Type: new Abstract: The extension of the analytic fractal curve trees of (2601.17490} to analytic surface patch trees reveals a new geometric structure: branch points are replaced by interface curves that transmit the full analytical state of parent patches to their children. These interfaces prove to be central in determining the topology of the surface patch trees, including for the conditions for self-similarity of the interfaces, the patches and thus the trees. We establish the...
Developing application programming interfaces at DfT
Developing application programming interfaces at DfT Outlines the feasibility of making as many existing open datasets as possible available through application programming interfaces (APIs) at the Department for Transport. Documents Details In the Department for Transport’s (DfT) data action plan, application programming interfaces (APIs) are defined as: - the default delivery channel for transport data - the main enabler of integration across modes and organisations - essential for...
WeaveBench: A Long-Horizon, Real-World Benchmark for Computer-Use Agents with Hybrid Interfaces
arXiv:2606.09426v1 Announce Type: new Abstract: Computer-use agents (CUAs) increasingly operate in runtimes that combine visual desktop control, command-line execution, code editing, browsers, and external tools. Existing benchmarks, however, often evaluate these interfaces as separable capabilities, leaving long-horizon cross-interface orchestration under-tested. Thus, we introduce WeaveBench, a long-horizon hybrid-interface benchmark with 114 tasks across 8 real-world work domains,...
A Mixed Extended Virtual Element Method for Elliptic Interface Problems on Polygonal Meshes
arXiv:2606.08526v1 Announce Type: new Abstract: We propose a lowest-order \(H(\operatorname{div})\)-conforming mixed extended virtual element method for elliptic interface problems on interface-unfitted polygonal meshes. The flux and pressure are approximated by subdomain-wise extended \(H(\operatorname{div})\)-VEM spaces and by piecewise constants, respectively. On cut elements, the computable polynomial projection is defined on the whole background element and then restricted to the two...
Meltwater transport and mixing layer growth near the ice--ocean interface
Announce Type: replace Abstract: Ice melting into saline water plays a fundamental role in the dynamics near the ice-ocean interface in polar oceans. The physics of ice melting involves a non-trivial interplay between thermodynamics at the interface, hydrodynamic transport in the bulk and the properties of the ambient ocean. The key control parameters are the density ratio $R_\rho$ proportional to the ambient ocean salinity and the Lewis number $Le = \kappa_T/\kappa_S$, which compares the...
New X-ray method captures solid-liquid interfaces and bulk liquids simultaneously
Researchers have developed a method for making simultaneous soft X-ray absorption spectroscopy (XAS) measurements of solid-liquid interfaces and bulk liquids. By controlling the thickness of the liquid layer, they obtained the O K-edge XAS spectrum of bulk H2O from a liquid H2O layer on a thin Au film using the transmission method, and they used the electron-yield method to obtain the XAS spectrum of the H2O/Au interface by measuring the drain currents from the Au surface following soft...
Comparing LLM-Based Conversational and Graphical Interfaces for Industrial Decision Tasks: An Exploratory Mixed-Methods Study
Announce Type: new Abstract: The use of Generative AI Conversational User Interfaces (CUI) as a new way to access and analyze data is growing in all sectors, and the industrial one is no exception. There, large amounts of data produced by IoT devices are flowing through user interfaces and may require them a new adaptation to the new analyses needs of decision-makers. LLM-based CUIs are promising a new way to directly interact with those data through the directness of natural language and...
