The p53 tumor suppressor gene is mutated in a large percentage of human malignancies, including tumors of the colon… Expand BACKGROUND
The powers of the low-frequency (LF) and high-frequency (HF) oscillations characterizing heart rate variability (HRV… Expand We develop a general method for power spectrum analysis of three dimensional redshift surveys. We present rigorous analytical… Expand An analytic model is described for application in ultrasonic tissue characterization. The model is applicable to clinical… Expand Power spectrum analysis of heart rate fluctuations provides a quantitative noninvasive means of assessing the functioning of the… Expand A summary of many of the new techniques developed in the last two decades for spectrum analysis of discrete time series is… Expand The output of an array of sansors is considered to be a homogeneous random field. In this case there is a spectral representation… Expand The use of the fast Fourier transform in power spectrum analysis is described. Principal advantages of this method are a… Expand
