Every year, a 20-metre Christmas tree from Norway is erected in Trafalgar Square. Image: iStock/stockcam "Trafalgar Square is changed as never before. A 48-ft Christmas tree has sprung up on the west ...

I’m walking in the Eifel Mountains in western Germany, through cathedral-like groves of oak and beech, and there’s a strange unmoored feeling of entering a fairy tale. The trees have become vibrantly ...

Each line segment of a distance-time graph represents one part of a journey. A distance-time graph, sometimes referred to as a travel graph, is a way of representing a journey. It is helpful to have ...

The recent past has seen an increasing interest in Heterogeneous Graph Neural Networks (HGNNs), since many real-world graphs are heterogeneous in nature, from citation graphs to email graphs. However, ...

Abstract: Data availability (DA) attack is a well-known problem in certain blockchains where users accept an invalid block with unavailable portions. Previous works have used LDPC and 2-D Reed Solomon ...

We consider the detection of activations over graphs under Gaussian noise, where signals are piece-wise constant over the graph. Despite the wide applicability of such a detection algorithm, there has ...

Abstract: The minimum spanning tree (MST) plays an important role in variant fields, such as chip design and network analysis. With the rapid expansion of vertices in real-life graphs, the bottleneck ...
