Quarterly Journal of the Royal Meteorological Society, EarlyView.Short‐term extreme rainfall can be produced by the variation of low‐level warm moist airflow during mesoscale convective systems (MCSs) approaching another. The cold outflow of the rapidly moving MCS intensifies the warm moist airflow in front, enhancing the convergence and ascending motion in the quasi‐stationary MCS.

, 2013 Summary: Let \(G\) be a connected graph of order \(n\) with Laplacian eigenvalues \(\mu_1\geq\mu_2\geq\cdots\geq\mu_{n-1}>\mu_n=0\). The Laplacian energy of the graph \(G\) is defined as \(LE=LE(G)=\sum_{i=1}^n| \mu_i-2m/n| \). Upper bounds for \(LE\) are obtained in terms of \(n\) and the number of edges \(m\).

On the neighbourhood degree sum-based Laplacian energy of graphs
Kuwait Journal of ScienceA useful extension of the Laplacian matrix is proposed here and the corresponding modification of the Laplacian energy (LE) is presented. The neighbourhood degree sum-based Laplacian energy (LNE) is produced by means of the eigenvalues of the newly ...

The Laplacian spectrum of weighted composite networks and the applications
AIP AdvancesThe topological properties of the networks can be described by the Laplacian spectra, but resolving the Laplacian spectra of networks poses difficulties. In this study, a novel approach for solving the Laplacian spectrum of weighted composite networks is

CAAI Transactions on Intelligence Technology, EarlyView.Abstract Graph neural networks (GNNs) have revolutionised the processing of information by facilitating the transmission of messages between graph nodes. Graph neural networks operate on graph‐structured data, which makes them suitable for a wide variety of computer vision problems, such as link prediction, node classification, and graph classification.

Enhancing generalized spectral clustering with embedding Laplacian graph regularization
CAAI Transactions on Intelligence Technology, EarlyView.Abstract An enhanced generalised spectral clustering framework that addresses the limitations of existing methods by incorporating the Laplacian graph and group effect into a regularisation term is presented. By doing so, the framework significantly enhances discrimination power and proves highly effective in handling noisy data.

Seidel Laplacian Energy of Fuzzy graphs
EAI Endorsed Transactions on Energy WebThe energy of a graph is related to its spectrum, which is equal to the total of the latent values of the pertinent adjacency matrix. In this research work, we proposed some of the features and the energy of the Seidel Laplacian of a fuzzy graph.
