The continuous wavelet transform (CWT) based on complex Morlet wavelets is used to identify magnetic sources. After summarizing the theory of CWT, we discussed the relationship between scale and frequency. In real cases, the magnetic anomalies of adjacent sources always superimpose on each other in space and frequency, making the identification of magnetic(More)
Gold-based nanocrystals have attracted considerable attention for drug delivery and biological applications due to their distinct shapes. However, overcoming biological barriers is a hard and inevitable problem, which restricts medical applications of nanomaterials in vivo. Seeking for an efficient transportation to penetrate biological barriers is a common(More)
OBJECTIVE To evaluate the curative effect of external lumbar drainage combined with empirical antibiotics treatment on the postoperative culture negative meningitis. METHODS The clinical data of eighty post-operative meningitis patients with cerebrospinal fluid culture negative were retrospectively analyzed according to inclusive and exclusive criteria(More)
We applied a third-order correlation technique for identification of wavelet coefficients uncorrupted by noise by considering triple correlation coefficients of wavelet-signal correlations for thresholding. Various important theoretical results are stated and discussed for the wavelet modulus maxima method, VisuShrink method and HOS-based thresholding(More)
