We presented two rare cases of secondary seminal vesicle (SV) metastasis from hepatocellular carcinoma of the liver and renal cell carcinoma from the right kidney. Diagnosis of secondary SV metastasis should be made based on clinical history, radiolo

A separate-stator modular machine with biased flux is proposed in this paper. In this machine, the windings and the permanent magnets are located in two separate parts of the stator, which favors the heat dissipation and magnetic saturation reduction

Most lift systems are fed by a 3-Phase-3-Wire (3P3W) supply with unbalanced line currents and slightly unbalanced line voltages, as experienced by the authors. Then, power meters available in the market may not give a consistent total power factor (T

To provide a satisfactory lift service to super high-rise buildings (while maintaining a small footprint for the lift hoistways), ropeless multi-car per hoistway system may be the trend. In our previous paper, a simplified machine model and two primi

Based on a reduced two-compartment model, the dynamical and biophysical mechanism underlying the spike initiation of the neuron to extracellular electric fields is investigated in this paper. With stability and phase plane analysis, we first investig

In recent years, buildings have become taller and wider. The conventional approach of one roped elevator car per hoistway seems increasingly impractical. The idea of ropeless elevators using linear motors was proposed more than 30 years ago, but it w

The term “Total Power Factor” defined as the ratio between the active power and the apparent power (consisting of active, reactive and distortion power) of an electrical system has been used for years to describe how good an electrical supply sys

Hybrid-excited permanent magnet (PM) machines incorporate the merits of both the PM machines and the electric-excited machines, but they usually need slip rings and brushes for the electric excitation and their structures are usually quite complex. I
