Generalized adiabatic impulse approximation [PDF]
Physical Review A, 2022 Non-adiabatic transitions in multilevel systems appear in various fields of physics, but it is not easy to analyze their dynamics in general. In this paper, we propose to extend the adiabatic impulse approximation to multilevel systems. This approximation method is shown to be equivalent to a series of unitary evolutions and facilitates to evaluate the

Influences of Impulse Generators on the Impulse Characteristics of Grounding Systems
Bulletin of Electrical Engineering and InformaticsIt is important to ensure the effectiveness of the experimental test set up and to accurately characterize grounding systems under high impulse conditions, the study on the effect of impulse generator is therefore needed. As with other experimental work, the test results may be influenced not only by the characteristics of the test load under study ...

Hematoma-induced Twiddler-like phenomenon as a presentation of DBS hardware failure: Case report
Frontiers in Human Neuroscience, 2023 Deep brain stimulators (DBS) may fail for a multitude of reasons. We present a 79-year-old Parkinson's disease patient who suffered a DBS failure following impulse generator (IPG) replacement surgery due to the IPG flipping within an expanded capsular ...

Landslide generated impulse waves. [PDF]
Experiments in Fluids, 2003 Landslide generated impulse waves were investigated in a two-dimensional physical laboratory model based on the generalized Froude similarity. Digital particle image velocimetry (PIV) was applied to the landslide impact and wave generation. Areas of interest up to 0.8 m by 0.8 m were investigated.
