It is necessary that something is donated from the healer, that is, something results from his organic metabolism. Also, based on your physical, mental, and emotional health, the energy resulting from your metabolism is assumed to be healthy for the healing of patients. On the other hand, also in many cases, healing does not occur due to the “vicious” quality of the energy to be transfused and the low receptivity of the patient. However, in most cases, it depends not only on the healer but also on the receiver, but usually on other healers, such as higher order consciousnesses. In fact, in many cases of healing, the effect is almost instantaneous with just the healer’s “magnetic energy”, especially in painful crises. Without a doubt, I believe that biophoton is an anti-inflammatory, analgesic, antibacterial and immunomodulatory bioenergy. The healing effectiveness of these therapies is well established. It is a cell-restoring product that can rebuild tissues and organs in a short time, which in many cases leads to the restoration of the patient’s health and well-being. The aim of this study is to address a brief history of ancestral energies of Asian philosophy (Chinese, Japanese and Indian), highlight the role of consciousness and the healer in healing therapies. In addition, the study emphasizes the similarity of these energies with the one called “ectoplasm”, as well as it establishes connections with the newly elected ultra-weak emission of photons. Finally, bibliographic research was carried out in an English language database and innovative concepts were introduced about the role of consciousness as well as the healer in healing therapies.展开更多

The demodulation system for signal acquisition and high-speed wavelength calculation was designed based on field programmable gate array (FPGA) platform. The principle of ultra-weak fiber Bragg grating high-speed demodulation and signal recognition method were analyzed theoretically, and the Support Vector Machine model was introduced to optimize the event recognition accuracy of the system. A perimeter security experimental system containing 1000 ultra-weak fiber Bragg gratings, ultra-weak fiber Bragg grating sense optical cables with a diameter of 2.0 mm and a reflectivity of 0.01%, steel space frames and demodulation equipments was built to recognize four typical events such as knocking, shaking, wind blowing and rainfall. The experimental resulted show that the system has a spatial resolution of 1m and an acquisition frequency of 200 Hz. The joint time-frequency domain detection method is used to achieve 99.2% alarm accuracy, and 98% recognition accuracy of two intrusion events, which has good anti-interference performance.展开更多
