ObjectivesThis study sought to assess agreement between an intravascular near-infrared spectroscopy (NIRS) system and histology in coronary autopsy specimens.BackgroundLipid core plaques cannot be detected by conventional tests, yet are suspected to

In this paper a novel signal-preprocessing technique that combines the local and multiscale properties of the wavelet prism with the global filtering capability of orthogonal signal correction (OSC) is presented for the pretreatment of spectroscopic

Piecewise orthogonal signal correction (POSC), an algorithm that performs local orthogonal filtering, was recently developed to process spectral signals. POSC was shown to improve partial leastsquares regression models over models built with conventi

To date, few efforts have been made to take simultaneous advantage of the local nature of spectral data in both the time and frequency domains in a single regression model. We describe here the use of a novel chemometrics algorithm using the wavelet

Taking advantage of the local nature of spectral data in both the time and frequency domains, two novel chemometric algorithms using the wavelet transform, namely dual-domain partial least squares (DDPLS) and dual-domain principal component regressio

Fluctuation in characteristic parameters of the equivalent circuit for the thickness-shear-mode (TSM) acoustic wave sensor is a troublesome problem encountered in their practical applications. It is due to interference from normal and non-normal nois

The urea-urease system was chosen as a model system to explore the suitability for the use of a bulk acoustic wave impedance sensor (BAWIS) as a detector in an immobilized enzyme FIA system. In the proposed FIA sysem, the urea in samples was hydrolyz

The permeation of water and corrosive species in coating films is very important for the corrosion protection by organic coatings. As a new method for the study of diffusion of media in coating films, bulk acoustic wave (BAW) admittance analysis has

A simple, inexpensive, on-line bulk acoustic wave (BAW) DNA biosensor is proposed. DNA is immobilized onto an Ag-plated surface rather than the conventional Au surface. Thioglycollic (TGC) acid is used as an active coating for DNA immobilization. The
