An Accurate Evaluation of Switching Impulse Voltages for High-Voltage Tests
Energies, 2022 For assessment of the insulation performance of high-voltage (HV) equipment installed in extra-high-voltage (EHV) systems, switching impulse voltage tests are performed in an HV testing laboratory.

GENERATION AND SPATIAL PROPAGATION OF LANDSLIDE GENERATED IMPULSE WAVES [PDF]
Coastal Engineering Proceedings, 2017 Large subaerial mass wasting into water may generate large waves along coast lines and in bays. Hazard assessment of such an events is based on the decay rate of these impulse waves along their propagation path to populated areas and infrastructure along the shoreline.

From mice to humans—divergent strategies for intestinal homeostasis and regeneration
FEBS Letters, EarlyView.Recent advances such as organoid genome editing, xenotransplantation, imaging, and whole‐genome sequencing have enabled direct studies of human intestinal stem cells (ISCs). These studies reveal species‐specific features, including slower ISC proliferation, distinct injury responses, slower somatic mutation accumulation in humans, and an inverse ...

Impulsive control of a nuclear spin generator
Journal of Computational and Applied Mathematics, 2003 Impulsive control of a nuclear spin generator is considered. Let be \[ X^T= (X_1,X_2,X_3),\qquad A= \begin{pmatrix} -\beta & 1 & 0\\ -1 &\beta(\gamma- 1) & 0\\ 0 & 0 & -\alpha\beta\end{pmatrix}, \] \[ \Phi(X)= \beta\gamma\begin{pmatrix} 0\\ -X_2 X_3\\ X^2_2\end{pmatrix},\qquad \alpha\in (0,1],\quad \beta,\gamma\in \mathbb{R}_+. \] The impulsive control

Structural insights and therapeutic targets in Acinetobacter baumannii capsule biosynthesis
FEBS Letters, EarlyView.Hypervirulent KL49 A. baumannii's capsular polysaccharide contains the nonulosonic acid 8‐epi‐Leg5,7Ac2, synthesized by epimerization via ElaA, ElaB, and ElaC. Crystal structures of ElaA, ElaB, and ElaC reveal their role in CMP‐Leg5,7Ac2 synthesis and regioselective C8 epimerization.

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 ...
