On a new structure of the pantograph inclusion problem in the Caputo conformable setting
Boundary Value Problems, 2020 In this work, we reformulate and investigate the well-known pantograph differential equation by applying newly-defined conformable operators in both Caputo and Riemann–Liouville settings simultaneously for the first time.

The existence and asymptotic estimations of solutions to stochastic pantograph equations with diffusion and Lévy jumps [PDF]
, 2015 In this paper, we consider a class of stochastic pantograph differential equations with Lévy jumps (SPDEwLJs). By using the Burkholder-Davis-Gundy inequality and the Kunita's inequality, we prove the existence and uniqueness of solutions to SPDEwLJs ...

Rapid Coupling Prediction for Compact GNSS Arrays via Graph Transformer
Electronics Letters, Volume 61, Issue 1, January/December 2025.The design of compact GNSS antenna arrays requires rapid evaluation of mutual coupling effects, which conventional full‐wave simulations fail to deliver due to excessive computational costs. This letter proposes a graph transformer model that predicts coupling matrices in real time. By hybridizing the local perception of graph isomorphism network (GIN)
