Exploring the giant monopole resonance in superheavy nuclei: A theoretical perspective
Within the relativistic mean field framework, in an extended Thomas-Fermi approximation, we calculate the binding energy and charge distribution radius for the latest superheavy nuclei, synthesised in various laboratories, with atomic numbers $Z = 110-118$. The binding energy and radii are compared...
DataScout: Automatic Data Fact Retrieval for Statement Augmentation with an LLM-Based Agent
A data story typically integrates data facts from multiple perspectives and stances to construct a comprehensive and objective narrative. However, retrieving these facts demands time for data search and challenges the creator’s analytical skills. In this work, we introduce DataScout, an interactive...
Generating isolated elliptically polarized attosecond pulse in gapped graphene using linearly polarized laser fields
We employ the two-band density-matrix equations to calculate high-order harmonic generation (HHG) and its ellipticity in gapped graphene irradiated by a femtosecond short-pulse laser under different orientation angles. The orientation-dependent harmonic spectra show obvious enhancement harmonics. We also focus on the ellipticity...
Dynamic Approximate Maximum Matching in the Distributed Vertex Partition Model
We initiate the study of approximate maximum matching in the vertex partition model, for graphs subject to dynamic changes. We assume that the $n$ vertices of the graph are partitioned among $k$ players, who execute a distributed algorithm and communicate via message...
Bridging Optical Sensing and Wearable Health Monitoring: A Functionalized Plasmonic Nanopillar for Non-Invasive Sweat Glucose Detection
Continuous glucose monitoring (CGM) is vital for diabetes care, but current systems rely on invasive implants or electrochemical sensors that often cause discomfort and skin irritation. Non-invasive alternatives remain limited by low sensitivity and poor compatibility with complex sweat environments, highlighting the...
Fréchet Distance in Unweighted Planar Graphs
The Fr\’echet distance is a distance measure between trajectories in the plane or walks in a graph G. Given constant-time shortest path queries in a graph G, the Discrete Fr\’echet distance $F_G(P, Q)$ between two walks P and Q can be computed...
TimeChat-Online: 80% Visual Tokens are Naturally Redundant in Streaming Videos
The rapid growth of online video platforms, particularly live streaming services, has created an urgent need for real-time video understanding systems. These systems must process continuous video streams and respond to user queries instantaneously, presenting unique challenges for current Video Large Language...
A Rellich-type theorem for the Helmholtz equation in a junction of stratified media
We prove that there are no non-zero square-integrable solutions to a two-dimensional Helmholtz equation in some unbounded inhomogeneous domains which represent junctions of stratified media. More precisely, we consider domains that are unions of three half-planes, where each half-plane is stratified in...
M-MRE: Extending the Mutual Reinforcement Effect to Multimodal Information Extraction
Mutual Reinforcement Effect (MRE) is an emerging subfield at the intersection of information extraction and model interpretability. MRE aims to leverage the mutual understanding between tasks of different granularities, enhancing the performance of both coarse-grained and fine-grained tasks through joint modeling. While...
Data-Driven Surrogate Modeling Techniques to Predict the Effective Contact Area of Rough Surface Contact Problems
The effective contact area in rough surface contact plays a critical role in multi-physics phenomena such as wear, sealing, and thermal or electrical conduction. Although accurate numerical methods, like the Boundary Element Method (BEM), are available to compute this quantity, their high...
