In applications where motor inversion is forbidden, it is important to detect the initial rotor position of the motor. For this reason, based on coupling injection of high-frequency signal, a novel ...

A novel high selectivity sheet-metal diplexer with multiple transmission zeros using frequency dependent couplings (FDC) is proposed. Compared with the traditional cross coupling, the frequency ...

Out of 17 modifiable risk factors, high blood pressure has the biggest impact on the risk of stroke, dementia, and late-life depression, according to new research. Along with lowering your blood ...

The performance of mass spectrometers with limited pumping capacity is shown to be improved through use of a discontinuous atmospheric pressure interface (DAPI). A proof-of-concept DAPI interface was ...

In comparison to traditional single-layer microbubbles, the MLBs can be used as a novel promising model of contrast agent for high-performance ultrasound imaging. The ultrasound signal of MLBs shows a ...
