Exact Quantization of Nonreciprocal Quasilumped Electrical Networks

Physical Review X
Following a consistent geometrical description previously introduced [Quantum 8, 1466 (2024)2521-327X10.22331/q-2024-09-09-1466], we present an exact method for obtaining canonically quantizable Hamiltonian descriptions of nonlinear, nonreciprocal ...

On the Method of Harmonic Balance for Lumped‐Element Transformer Models

International Journal of Circuit Theory and Applications, EarlyView.
The steady‐state solution of a lumped‐element transformer model with a dry friction‐like hysteresis model depicting the magnetic core is of interest. The harmonic balance method efficiently solves this stiff system. We derive the harmonic balance algorithm, enhance it with performance and convergence improvements, and demonstrate its efficiency by ...

Complete Flow for PCB Design Consideration and Power/Signal Integrity Analysis Based on Broadband Model of Parasitic Elements

International Journal of Circuit Theory and Applications, EarlyView.
An implementation of a broadband model for the generation of an accurate time‐domain description of parasitic elements from frequency‐domain electromagnetic (EM) simulator results is proposed. It is designed to work simultaneously at low and high frequencies, bypassing EM simulators limitations, validating it against measurement and presenting a ...

Physiology–microhabitat matching may help organisms cope with the thermal and hydric challenges under climate change: a tale of two lizards

Ecography, EarlyView.
Climate change is significantly affecting biodiversity, and organisms that depend on external temperature – such as ectotherms – are particularly vulnerable to these effects. Microhabitats provide refuge for species, thereby reducing exposure to thermal and hydric stress under climate change.

Digital Rights Activism in Multilevel Governance

European Policy Analysis, EarlyView.
ABSTRACT Multilevel governance (MLG) without a clear hierarchical structure can create power imbalances among various actors, particularly in settings with overlapping jurisdictions and policy areas. This dynamic is especially pronounced in Internet governance, which faces a complex interplay of domestic laws, state interdependence, and heightened ...

Noise, Vibration, and Harshness (NVH) Challenges in Hydrogen Internal Combustion Engine Vehicles

Energy Science &Engineering, EarlyView.
ABSTRACT This paper presents a state‐of‐the‐art literature review on noise, vibration, and harshness (NVH) in hydrogen‐fuelled internal combustion engines. Studies published between 2011 and 2025 were screened, covering fundamental flame physics, test‐bench work, and recent prototype vehicles.
