In this paper, the Coaster Round nonlinear dynamics of a PV-fed high-voltage-gain single-switch quadratic boost converter loaded by a grid-interlinked DC-AC inverter is explored in its parameter space.The control of the input port of the converter is designed using a resistive control approach ensuring stability at the slow time-scale.However, time
Chronic obstructive pulmonary disease (COPD) and heart failure (HF) are two of the most common conditions treated in internal medicine.Although it is known that these diseases often coexist, the specific characteristics of the affected Gift Card patients and the prognostic implications are not yet well understood.Managing patients with both COPD an
This report presents the case of a 68-year-old female patient with hepatocellular carcinoma (HCC) who experienced persistently elevated alpha-fetoprotein (AFP) levels following resection of the primary liver tumor.The patient had previously undergone transcatheter arterial chemoembolization (TACE) and liver SUNFLOW VIT E tumor resection, but postop
Ocean Jacks acidification (OA) generally refers to the ongoing decrease in ocean pH.Ocean acidification is caused primarily by the oceanic uptake of excess carbon dioxide (CO2) from the atmosphere.Other impacts related to climate change (increased sea level rise, coastal flooding and extreme weather events) often receive more attention than OA, but
Spin-crossover (SCO) materials have for more than 30 years stood out for their vast application potential in memory, sensing and display devices.To reach magnetic multistability conditions, the high-spin (HS) and low-spin (LS) states have to be carefully balanced by ligand field stabilization and spin-pairing energies.Both effects could be effectiv
