Plants have evolved efficient mechanisms for adapting to temperature fluctuations, known as heat stress response and heat stress memory. Although the transcriptional regulatory network of plant heat stress response has been established, little is known about the genome‐wide transcriptional changes occurring within the first several minutes after heat shock. Here, we investigated the nascent RNA and...
The aim is to characterize the effects of cardiovascular on heart rate variability(HRV) by the nonlinear dynamical parameter complexity measure of the HRV signal. The method is that the electro-cardiogram signals of 20 normal samples and 107 various patient samples are collected. Based on the preprocessing for the raw data, the HRV signals of all samples are extracted from electrocardiogram signals...
The aim of this study is to describe the effects of harmonic noise on the complexity measure of nonlinear dynamic systems by numerical simulation. Four types of nonlinear time sequences are superimposed by harmonic noise. The complexity measures of all sequences are calculated and analyzed. By the experimental and statistical results, the value of the complexity measure of the sequence is decreasing...
Heart rate variability(HRV) is an important index to express the tensility and balance of the parasympathetic- sympathetic nerve, and it is valuable to diagnose heart and blood disease in clinical diagnosis. It was approved that HRV signal possess nonlinear characteristic, and we can analysis and represent HRV signal by nonlinear dynamic parameter, such as correlation dimension. In this paper, We...
EEG signal is a typical nonlinear time series and its correlation dimension can be calculated to measure the series. In this paper, the correlation dimensions of 30 healthy samples and 30 patient samples are calculated. By the statistic result, an important conclusion is represented that the values of correlation dimension of different groups exist great difference. Based on more clinical experiments,...
