Abstract Type II endometrial cancer, which mainly presents as serous and clear cell types, has proved to be the most malignant recurrent carcinoma among various female genital malignancies. The transcription factor Nrf2 was first described having chemopreventive activity. Activation of Nrf2-mediated cellular defense response protects cells against toxic carcinogenic effects environmental insults by upregulating an array genes that detoxify reactive oxygen species restore redox homeostasis....
As a prototype single-phase multiferroic, BiFeO3 exhibits excellent electrical, magnetic, and magnetoelectric properties, appealing to many modern technological applications. One of its overlooked merits is high piezoelectric performance originating from large remnant polarization (Pr) low dielectric constant (εr). Furthermore, Curie temperature coercive field ensure good stabilities in device However, achieve close-to-intrinsic processing usually used for the preparation highly crystalline...
Ultrasonic motor (USM) combines piezoelectric actuator with friction drive, and there is a non-negligible speed fluctuation. The pulsation of the rotating affects stability accuracy ultrasonic motor. In order to describe inherent characteristics fluctuation characteristics, this paper first analyses error source eccentric inclination shaft relative stator, tests rotor under different parameters in comprehensive experimental device driven by multiple parameters. Finally, results are analysed...

With the technical development of wind power forecasting, making generation schedule in systems become an inevitable tendency. This paper proposes a new dispatch method for farm (WF) cluster by considering forecasting errors. A probability distribution model errors and mathematic expectation shortage caused are established. Then, total from all WFs is minimized. Case study with respect to WF conducted using actual data within 30 days sites located at Gansu Province. Compared variable...
The paper proposes a three-degrees-of-freedom flexible nano-positioning stage constructed from compliant flexures and piezoelectric thin-sheet actuators, featuring compact size fast dynamic responses, which can be extensively applied to the typical micro/nano-positioning applications. Meanwhile, model of PZT with distributed parameter characteristics is established distinctly reflect piezoelectric–mechanical coupling relationship between four actuators three outputs such system. Furthermore,...
This paper investigates the pre-pressure’s influence on key performance of a traveling wave ultrasonic motor (TRUM) using simulations and experimental tests. An analytical model accompanied with power dissipation is built, an electric cylinder first adopted in regulating pre-pressure rapidly, flexibly accurately. Both results provide several new features for exploring function pre-pressure. It turns out that proportion driving zone within contact region declines as increases, while lower...
Abstract. This paper develops an electromechanical TWUSM (traveling-wave ultrasonic motor) model combining the driving circuit with motor itself. An equivalent substituted for piezoelectric ceramics is designed in to obtain accurate input currents and powers. Then teeth discretization implemented stator–rotor contact model, which can calculate interaction forces more accurately. After building complete of TWUSM, a typical startup–stopping process divided into five stages by evaluating...
