Abstract

The present invention relates to a method for determining sensitivity to a PARP inhibitor or a DNA damaging agent by using a non-functional transcriptome, and more particularly, to a method for determining sensitivity to a PARP inhibitor or a DNA damaging agent by extracting nucleic acids from a biological sample to obtain the expression amount of each of non-functional transcriptomes of DNA repair-related genes, and then analyzing the use rate (TU) of each of the non-functional transcriptomes for each gene on the basis of the obtained expression amount. The method for determining sensitivity to a PARP inhibitor or a DNA damaging agent according to the present invention is useful in that sensitivity can be determined in real time with high accuracy because the method uses information of the transcriptomes transcribed in the gene, unlike existing methods which determine sensitivity to a PARP inhibitor or a DNA damaging agent on the basis of genetic variation information.

Abstract

A method for detecting fatigue cracks in a structure and a system therefore are disclosed. A vibration detection element detects vibration of the structure generated when the structure is excited at low and high frequencies and generates a measurement signal in the time domain. Based on a trained long short-term memory (LSTM) network, a signal of the next time step is predicted from the measurement signal of the current time step measured by the vibration detection element. The measurement signal and the prediction signal are combined to create a new combined signal with an increased length in the time domain. The combined signal is Fourier transformed to reduce noise and enhance the information of the measured signal in the frequency domain, and the Fourier transformed signal is used to obtain a spectral density function and to detect cracks in the structure.
