A Novel Non-Isolated High-Gain Non-Inverting Interleaved DC–DC Converter
Micromachines, 2023 High-gain DC–DC converters are being drastically utilized in renewable energy generation systems, such as photovoltaic (PV) and fuel cells (FC). Renewable energy sources (RES) persist with low-level output voltage; therefore, high-gain DC–DC converters ...

High Gain Placental Cardiovascular Control
Experimental Biology and Medicine, 1977 SummaryThe placentas of eight near-term goats were perfused with blood containing C2H2. The adult goats breathed gas containing N2O. Catheters were placed in a maternal femoral artery and uterine vein. Knowledge of the perfusion rate and N2O and C2H2 concentrations in the maternal artery, uterine vein, umbilical arteries, and umbilical veins, permitted

High-gain quantum free-electron laser: Emergence and exponential gain [PDF]
Physical Review A, 2019 We derive an effective Dicke model in momentum space to describe collective effects in the quantum regime of a free-electron laser (FEL). The resulting exponential gain from a single passage of electrons allows the operation of a Quantum FEL in the high-gain mode and avoids the experimental challenges of an X-ray FEL oscillator.
