Pulsed electric fields have recently been the focus of considerable attention because of their potential application in biomedicine. However, their practical clinical applications are limited by poor understanding of the interaction mechanism between pulsed electric fields and cells, particularly in different effect of electroporation exposed in different parameters, and the optimal pulsed parameter...
Muscle contraction and the non-uniform distribution of electric field have become the key obstacles which restrict the development of the irreversible electroporation in clinical application. To solve these two problems, a novel type of pulses called high-frequency composite pulses were proposed. The killing effect and the thermal effect were investigated in this paper. The high-frequency composite...
Pulsed power technology has been used for the ablation tumor. Considerable research shows that a high-strength unipolar pulse electric field can induce irreversible electroporation (IRE) on the cell membrane, which can effectively kill cells. But some scholars and doctors have found that muscle contractions occur during treatment, which are associated with the delivery of electric pulses. Confirmed...
Impulse frequency response analysis is one of the diagnostic methods for online detecting power transformer winding deformation, however, the existing method of obtaining impulse frequency response curves Fast Fourier Transform is actually not suitable because of its bases. A signal processing method based on Short Time Fourier Transform is proposed in this paper, the simulation and experiment are...
Irreversible electroporation (IRE) is a novel therapy that employs short high intense electric field to destroy the cytoskeletal structure and ablate the tissue, especially the tumor tissue. Compared to traditional treatment, IRE is a nonthermal therapy, which is not limited by the thermal sink near the blood vessel. However, the experiment of animals and the clinical trials all reveal that there...
In this work the modeling and calibration method of reciprocity error in a coherent TDD coordinated multi-point (CoMP) joint transmission (JT) system are addressed. The modeling includes parameters such as amplitude gains and phase differences of RF chains between the eNBs. The calibration method used for inter-cell antenna calibration is based on precoding matrix indicator (PMI) feedback by UE. Furthermore,...
After analyzing launching characters of ventilation system, water cycling system and circuit supply system in large warehouse systems, PHM (Prognostics and Health Management) technology applications in large warehouse systems is discussed in terms of maintainability and supportability, and a framework of maintenance support mode for large warehouse systems is proposed based on PHM. The foundation...
