Terahertz (THz) spectroscopy is now achieving increasing attention in security inspection
owning to its non-destructiveness and deep penetrability of most packaging materials, such …

The potential of time series of Sentinel-1 (S1) Synthetic Aperture Radar (SAR) data for
monitoring crops and their phenological stages has long been recognized. However …

This paper presents a method for the protected geographical indication discrimination of
Ophiopogon japonicus from Zhejiang and elsewhere using near-infrared (NIR) spectroscopy …

As the main fluorescent substances in oils, polycyclic aromatic hydrocarbons (PAHs) are the
basis of ultraviolet (UV)-induced fluorescence spectroscopy methods to detect oil films on …

Savitzky-Golay (SG) filters are finite impulse response (FIR) realizations of least-squares
polynomial regression and they are widely used for filtering (eg smoothing, interpolating …

PU foams are versatile materials that find applications in a wide range of products, from
upholstery to packaging and construction. These foams consist primarily of two components …

Physiological function is regulated through cellular communication that is facilitated by
multiple signaling molecules such as second messengers. Analysis of signal dynamics …

A perfect denoising for measurement shall remove noise, while keeping signal truth, so it is
a dual-objective optimization of the signal yield and the noise residue. The frequency …

Research has shown multiscale entropy, brain signal behavior across time scales, to reliably
increase at lower time scales with time-on-task fatigue. However, multiscale entropy has not …

Noise fluctuation is the most common issue of small heat flux measurement and it disturbs
the measurement precision. In the previous studies, how to select an appropriate filter and …
