Investigation of propagation of partial discharges in power transformers and techniques for locating the discharge [PDF]
, 2005 The location of partial discharges in a power transformer can be determined based on the characteristics of the transfer function from the discharge source to the measuring terminal.

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 ...

Multiple modular DC transformer for flexible HVDC application
The Journal of Engineering, 2019 This study proposes a novel multiple modular dc transformer (MMDCT) scheme for flexible high-voltage dc (HVDC) application. The MMDCT is composed of n consistent modular dual-active-bridge converters (MDABs), and every MDAB can work independently.

Variation of Core Loss in High-Frequency Transformers Under Different Load Conditions
IEEE Open Journal of the Industrial Electronics Society, 2023 Typically, the core loss of transformers is considered constant, regardless of the load conditions on the secondary side. However, this assumption is no longer valid for high-frequency transformers (HFTs).
