Heart is a vital organ of the human body which plays an important role in the circulation of the blood throughout the body and also serves as the power source of the electrical impulses that generate the rhythmicity of the heart thus resulting in the successful circulation of the blood. Now any disturbance in the proper functioning of the heart results in some type of diseases termed as cardiov...

We describe an algorithm for the automated statistical analysis of protein abundance ratios (ASAPRatio) of proteins contained in two samples. Proteins are labeled with distinct stable-isotope tags and fragmented, and the tagged peptide fragments are separated by liquid chromatography (LC) and analyzed by electrospray ionization (ESI) tandem mass spectrometry (MS/MS). The algorithm utilizes the ...

BACKGROUND Quantification cycle (Cq) and amplification efficiency (AE) are parameters mathematically extracted from raw data to characterize quantitative PCR (qPCR) reactions and quantify the copy number in a sample. Little attention has been paid to the effects of preprocessing and the use of smoothing or filtering approaches to compensate for noisy data. Existing algorithms largely are taken ...

Dicofol is a highly toxic residual pesticide in tea, which seriously endangers human health. A method for detecting dicofol tea by combining stoichiometry with surface-enhanced Raman spectroscopy (SERS) technology was proposed this study. AuNPs were prepared, and silver shells grown on the surface of to obtain core–shell Au@AgNPs. Then, Au@AgNPs attached PDMS membrane physical deposition Au@AgN...

In this paper, a moving-average method of smoothing noise based on complex exponential decomposition is applied to eliminate non-stationary signal and non-linear produced by Bouc–Wen model, which are added white Gaussian simulate the in measured signal. The uses sliding window cutting entire and/or into small segments considers that stable linear. decomposed series components via decomposition,...

Accurately identifying the phenology of summer maize is crucial for both cultivar breeding and fertilizer controlling in precision agriculture. In this study, daily RGB images covering entire growth were collected using phenocams at sites Shangqiu (2018, 2019 2020) Nanpi (2020) China. Four phenological dates, including six leaves, booting, heading maturity maize, pre-defined extracted from phen...

direct orthogonal signal correction(dosc) and savitzky-golay filters (sgf) were applied as preprocessing methods on the original and first derivative absorbance data. principle component regression (pcr), partial least squares (pls) and iterative target transformation factor analysis (ittfa), were used in spectrophotometric simultaneous determination of heavy divalent metal ions, lead, zinc,mer...

a non-destructive, rapid and low-cost determination of date fruit moisture content is one of the most determining factors in maturity assessment and processing of this valuable product. on the other hand, the potential of near infrared (nir) spectroscopy in nondestructive internal quality evaluation of agricultural products has been proved throughout several studies. in this research, three mod...

This article presents a new subspace-based technique for reducing the noise of signals in time-series. In the proposed approach, the signal is initially represented as a data matrix. Then using Singular Value Decomposition (SVD), noisy data matrix is divided into signal subspace and noise subspace. In this subspace division, each derivative of the singular values with respect to rank order is u...

The petrochemical industry is a pillar for the development of national economy affecting people’s daily living standards. Crude distillation process core and leading unit industry. Its energy consumption accounts more than 20% total whole plant, which highest link. A model based on long short-term memory network (LSTM) proposed in this paper to predict analyze efficiency. This extracts complex ...
