Design, analysis, and implementation of a new high‐gain P‐type step‐up dc/dc converter with continuous input current and common ground

open access: yesIET Power Electronics, 2021
Step‐up converters are increasingly developed for renewable energy and storage systems in order to raise the output voltage of those resources to higher voltage levels.

The tarantula toxin GxTx detains K+ channel gating charges in their resting conformation. [PDF]

open access: yes, 2019
Allosteric ligands modulate protein activity by altering the energy landscape of conformational space in ligand-protein complexes. Here we investigate how ligand binding to a K+ channel's voltage sensor allosterically modulates opening of its K ...

Carcinomas and Carcinoid Tumors of the Lungs and Bronchi in Children and Adolescents: The EXPeRT Recommendations

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Primary lung carcinomas and bronchial carcinoid tumors (BC) are very rare malignancies in childhood. While typical BC and mucoepidermoid carcinomas are mostly low‐grade, localized tumors with a more favorable prognosis than in adults, necessitating avoidance of overtreatment, adenocarcinomas of the lung are often diagnosed at advanced disease ...

Effective battery charging system using step voltage and step duty size-based MPPT controller for solar PV system

open access: yesEnergy Reports, 2023
Solar energy is an excellent source of renewable energy, despite its intermittent nature that can pose a challenge. To meet load demand, a converter is required to integrate the system.

Pulse technique provides more accurate checkout of exploding bridge wire device [PDF]

open access: yes, 1966
Exploding Bridge Wire /EBW/ is treated as a transmission line system and pulse reflection techniques are used for checking the electrical integrity of an EBW cartridge.

Stationary Charge Imbalance Effect in System of Coupled Josephson Junction

open access: yes, 2019
We investigate stationary charge imbalance effect in the system of coupled overdamped Josephson junctions. We show that coupling between junction and nonzero stationary charge imbalance in the resistive state bring to a decrease of the Josephson ...

European Standard Clinical Practice Guideline and EXPeRT Recommendations for the Diagnosis and Management of Gastroenteropancreatic Neuroendocrine Neoplasms in Children and Adolescents

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Pediatric gastroenteropancreatic neuroendocrine neoplasms (GEP‐NENs) are extremely rare and clinically heterogeneous. Management has largely been extrapolated from adult practice. This European Standard Clinical Practice Guideline (ESCP), developed by the EXPeRT network in collaboration with adult NEN experts, provides (adult) evidence ...

Non-isolated high step-up DC–DC converter adopting auxiliary capacitor and coupled inductor

open access: yesJournal of Modern Power Systems and Clean Energy, 2017
For grid-connected power system based on photovoltaic (PV) source and fuel cells, high step-up and high-efficiency DC–DC converters are needed, due to the bus voltage of the grid-connected inverter is much higher than the output voltage of PV and fuel ...

Controllable high voltage source having fast settling time [PDF]

open access: yes, 1975
A high voltage dc stepping power supply for sampling a utilization device such as an electrostatic analyzer has a relatively fast settling time for voltage steps. The supply includes a waveform generator for deriving a low voltage staircase waveform that

Charge transport through weakly open one dimensional quantum wires

open access: yes, 2008
We consider resonant transmission through a finite-length quantum wire connected to leads via finite transparency junctions. The coherent electron transport is strongly modified by the Coulomb interaction.
