Dangerous signal mining method of dangerous goods transport vehicles and how to improve the accuracy of the mining are studied in the paper. There are many dangerous conditions such as high temperature, high pressure and other dangerous condition caused by the influence of the external factors such as friction in the transportation process of dangerous goods. If people can discover these danger...

Ear candling is an alternative medicine practice alleged to enhance general health by putting an end of a hollow candle in the ear canal and lighting up the other end of it. It also is advertised for cerumen and debris (bacteria and fungi) removal. Ear candling is claimed to create negative pressure for drawing cerumen from the ear and to benefit the ears in many ways. It is however not free o...

The three-loop effective potential of the massless O(N) φ4 theory is calculated analytically using techniques of dimensional regularization. We see a complete agreement between our result and Jackiw’s result obtained only up to two-loop order using a different regularization (cutoff regularization) method, but the same renormalization conditions. For an easy check of the mutual cancellation of ...
