Deep Quake Dynamics: A Multimodal Fault‐Aware Approach to Earthquake Magnitude and Occurrence Time Forecasting

Geoscience Data Journal, Volume 13, Issue 2, April 2026.
EQMT integrates earthquake catalog data, fault‐network geometry, engineered features, and graph embeddings in a unified framework for forecasting earthquake magnitude and occurrence time. The framework is designed to reflect inter‐fault spatial dependencies together with temporal seismic patterns, addressing limitations of approaches based only on ...

Mapping Intracellular Volume Fraction With Susceptibility Source Decomposition as a Marker for Tissue Cellularity

Journal of Magnetic Resonance Imaging, Volume 63, Issue 4, Page 1092-1105, April 2026.
ABSTRACT Background Pathophysiological changes affect tissue cell composition and density. For example, neurodegenerative disorders and brain tumors are associated with cell loss and abnormal accumulation, respectively. In these scenarios, if monitored and tracked, tissue cellularity might be used to inform clinical diagnosis and management. Purpose To

An Effective Physics‐Informed Neural Operator Framework for Predicting Wavefields

Journal of Geophysical Research: Machine Learning and Computation, Volume 3, Issue 2, April 2026.
Abstract Solving the wave equation is fundamental for many geophysical applications. However, numerical solutions of the Helmholtz equation face significant computational and memory challenges. Therefore, we introduce a physics‐informed convolutional neural operator (CNO) (PICNO) to solve the Helmholtz equation efficiently.

Homogeneous Observer‐Based Affine Formation Tracking

International Journal of Robust and Nonlinear Control, Volume 36, Issue 5, Page 2692-2704, 25 March 2026.
ABSTRACT This article addresses the control of mobile agents, termed followers, to track a time‐varying affine formation specified by a set of leaders. We present a distributed hierarchical method composed of a homogeneous high‐order sliding mode observer and a tracking controller. The observer estimates the followers' target trajectories from neighbor

Event‐Triggered Saturating Control for Synchronization of Lur'e Type Complex Dynamic Networks

International Journal of Robust and Nonlinear Control, Volume 36, Issue 4, Page 2184-2198, 10 March 2026.
ABSTRACT This article addresses the problem of synchronizing discrete‐time Lur'e type complex dynamic networks (CDNs) via dynamic event‐triggered control. In particular, it is considered that the control signal of each node is subject to input saturation. Using the Lyapunov Stability Theory, properties of slope‐restricted nonlinearities, and the linear

Graph Laplacians and topology

Arkiv för Matematik, 2008
Sturm-Liouville operators on metric graphs with zero potential are studied. It is shown that the spectrum and scattering data determine the length of the compact part of the graph, the number of connected components and the Euler characteristic.

Synthesis and Investigation of Bonding Scenario in a Bis(silaselenone)

European Journal of Inorganic Chemistry, Volume 29, Issue 7, 2 March 2026.
Silaselenones, the compounds containing Si=Se bond, are rarely reported in the literature. Silaselenones are the class of compounds that possess Si=Se bond. Herein, we report a bis(silaselenone) and we investigate nature of bonding between Si–Si atoms and Si—Amidinate moieties by employing Natural bond orbital (NBO), Quantum theory of atoms in ...

Spectral Decomposition of Chemical Semantics for Activity Cliffs‐Aware Molecular Property Prediction

Advanced Science, Volume 13, Issue 13, 3 March 2026.
PrismNet mimics chemical intuition by functioning as a computational prism, refracting molecular graphs into complementary semantic views and spectral frequencies. This dual‐decomposition strategy effectively captures both global topologies and subtle “activity cliff” perturbations.

ENERGY OF NON-COPRIME GRAPH ON MODULO GROUP

Barekeng
A graph is a mathematical structure consisting of a non-empty set of vertices and a set of edges connecting these vertices. In recent years, extensive research on graphs has been conducted, with one of the intriguing topics being the representation of ...
