A new approach to quantum backflow [PDF]
, 2005 We derive some rigorous results concerning the backflow operator introduced by Bracken and Melloy. We show that it is linear bounded, self adjoint, and not compact.

Performance Evaluation of Modulation Techniques in Single-Phase Dual Active Bridge Converters
IEEE Open Journal of the Industrial Electronics Society, 2021 This research presents a thorough comparison of different modulation techniques employed in dual active bridge (DAB) converters. The performance of a DAB converter is essentially affected by the modulation technique and the operating point, including ...

Simulating Electron Transport and Synchrotron Emission in Radio Galaxies: Shock Acceleration and Synchrotron Aging in Three-Dimensional Flows [PDF]
, 2001 We present the first three-dimensional MHD radio galaxy simulations that explicitly model transport of relativistic electrons, including diffusive acceleration at shocks as well as radiative and adiabatic cooling in smooth flows.

Minimum-Backflow-Power Scheme of DAB-Based Solid-State Transformer With Extended-Phase-Shift Control [PDF]
IEEE Transactions on Industry Applications, 2018 As key component for the flexible dc distributed power system, the dual active bridge (DAB)-converter-based solid-state transformer (SST) with high efficiency for a wide operating range is essential. However, with the traditional phase-shift control, high backflow power and current stress will significantly affect the conversion efficiency.

A Simulation Study of Ultra-relativistic Jets. III. Particle Acceleration in FR-II Jets
The Astrophysical Journal, 2023 We study the acceleration of ultra-high-energy cosmic rays (UHECRs) in Class II Fanaroff–Riley (FR-II) radio galaxies by performing Monte Carlo simulations for the transport, scattering, and energy change of CR particles injected into time-evolving jet ...

Backflows In- And Feedback From Jet-Powered Agns
, 2016 During the propagation of a jet within the Interstellar medium of its host galaxy an expanding cavity filled with hot, turbulent gas forms, within which the jet itself propagates. We have performed a series of numerical experiments aiming at studying the large scale circulation within this jet-cocoon system. The gas advected by this backflow has a very

Electronics, 2022 Electrowetting display (EWD) is one of the latest and most promising reflective displays. However, some defects are easily caused in a driving process. For example, the aperture ratio of pixels can be reduced due to oil splitting, and the grayscale cannot be stabilized due to charge trapping. These defects can be effectively solved by designing driving
