Transition system

In low-cost permanent magnet synchronous motor (PMSM) drive systems, the rotor position is usually estimated based on the back-electromotive force. However, such estimation methods have the common drawback of having large errors in low-speed regions. In order to solve that drawback in the startup phase, the I-f startup method is studied as its compatibility with the FOC control structure. The purpose of such a method is to make the motor accelerate and overcome the low-speed threshold.

Glioblastoma (GBM) is the most aggressive malignant central nervous system tumor with a poor prognosis.The malignant transformation of glioma cells via epithelial-mesenchymal transition (EMT) has been observed as a main obstacle for glioblastoma treatment. Epithelial membrane protein 3 (EMP3) is significantly associated with the malignancy of GBM and the prognosis of patients.

The growing number of older adults with chronic diseases challenges already strained healthcare systems. Fragmented systems make transitions between healthcare settings demanding, posing risks during transitions from in-patient care to home. Despite efforts to make healthcare person-centered during care transitions, previous research indicates that these ambitions are not yet achieved.

Ebook "Electron correlation in metals" discusses the following issues: enhancements of electronic specific heat and magnetic susceptibility, effects of electron correlation on transport phenomena such as electric resistivity and Hall coefficient, magnetism, Mott transition and unconventional superconductivity. These originate commonly from the Coulomb repulsion between electrons. In particular, superconductivity in strongly correlated electron systems is discussed with a unified point of view.

Today’s globalised world is well aware that the logistics in fossil fuel industry enables it to be the main contributor to greenhouse gas (GHG) emissions that cause global warming and climate change. Negative public opinion about the oil and gas industry is rising globally. A growing number of societies are proficient at varying public opinion about oil and gas industry emissions. In this context, oil and gas companies have begun to substantially invest in renewable energy sources in a bid to diversify their oil and gas product portfolios to mitigate climate change risks.
