From analogue to digital for high voltage impulse generator [PDF]
, 2014 An impulse generator is an electrical apparatus which produces short high-voltage or high-current surges. These devices can be classified into two types : (1) impulse voltage generators and (2) impulse current generators.

IEEJ Transactions on Power and Energy, 2007 This paper describes the theoretical analysis of lightning impulse voltage waveform with an overshoot or oscillation caused by the residual inductance of the impulse generator. The oscillating lightning impulse waveform is expressed by the following formula;vout (t) = A {e-α1t - e-α2t sin(ωt+θ)/sinθ}where A, α1, α2, ω, θ are constants, respectively ...

Periodic Solutions Generated by Impulses for State-Dependent Impulsive Differential Equation [PDF]
Discrete Dynamics in Nature and Society, 2015 We study the existence of periodic solutions for a class of state-dependent impulsive differential systems via geometrical analysis methods. Our results show that these periodic solutions are generated by impulses. Moreover, numerical simulations are used to examine the existence of the periodic solutions.

Molecular Oncology, EarlyView.We have established a humanized orthotopic patient‐derived xenograft (Hu‐oPDX) mouse model of high‐grade serous ovarian cancer (HGSOC) that recapitulates human tumor–immune interactions. Using combined anti‐PD‐L1/anti‐CD73 immunotherapy, we demonstrate the model's improved biological relevance and enhanced translational value for preclinical ...
