A Nonstationary Geometry‐Based Model for Channel Characterisation in Vactrains Scenarios Using Leaky Coaxial Cables

IET Microwaves, Antennas &Propagation, Volume 20, Issue 1, January/December 2026.
In this paper, a 3D multi‐source GBSM model is proposed for the vacuum tube scenario using LCX. By equating the periodic slots to multiple magnetic dipole antennas, the electric field distribution of LCX is deduced, and the CIR expression is derived. Based on this, the multi‐link spatial‐temporal correlations, including the spatial CCF and temporal ACF,

A Multi‐Objective Optimal Synchronous Modulation Strategy for Three‐Level Converter Through Switching Angle Regulation

IET Power Electronics, Volume 19, Issue 1, January/December 2026.
This paper proposes a novel power loss reduction PWM (PLRPWM) strategy for three‐level neutral point clamped inverters. The proposed strategy aims to achieve multi‐objective optimisation by balancing low output harmonics, reduced switching losses and a balanced neutral‐point potential. ABSTRACT Three‐level neutral point clamped (3L‐NPC) converters have

Bibliometric Analysis of Transport Infrastructure Hypernetwork: Review and Prospects

Journal of Advanced Transportation, Volume 2026, Issue 1, 2026.
The transport infrastructure is transitioning into a multilayer, multifunctional hypernetwork form, posing challenges to traditional single‐mode planning methods in analyzing cross‐system risk transmission mechanisms and achieving spatiotemporal resource optimization. This leads to suboptimal system synergy and resilience.

Optimal Model Order Reduction Technique for Dynamic Motor Vehicle Suspension Systems

Journal of Applied Mathematics, Volume 2026, Issue 1, 2026.
High‐fidelity full‐vehicle suspension models with hundreds to thousands of states are computationally prohibitive for real‐time control and virtual prototyping. Existing model reduction techniques distribute approximation effort uniformly across the entire frequency spectrum, producing unnecessarily large errors in the (6–10)‐Hz band where human ...

Conservation Laws and Dynamics of Solitons to the Multicomponent Fractional Gross–Pitaevskii System: Application in the Bose–Einstein Condensation

Journal of Mathematics, Volume 2026, Issue 1, 2026.
In this work, we study the β‐fractional multicomponent Gross–Pitaevskii (G–P) system, which plays an important role in modeling Bose–Einstein condensates (BECs) and propagation in nonlinear waves. In Bose–Einstein condensation, the G–P equation is of great importance as it describes the condensate wave function’s behavior.
