Memristors and magnetic tunnel junctions are showing great potential in data storage and computing applications. A magnetoelectrically coupled memristor utilizing electron spin and electric field-induced ion migration can facilitate their operation, uncover new phenomena, and expand applications. In this study, devices consisting of Pt/(LaCoO/SrTiO)/LaCoO/Nb:SrTiO (Pt/(LCO/STO)/LCO/NSTO) are engineered using pulsed laser deposition to form the LCO/STO superlattice layer, with Pt and NSTO serving as the top and bottom electrodes, respectively.

To analyze the differences and dynamic changes in the color, odor, and major chemical components of Astragali Radix during honey processing, this study used a CM-5 spectrophotometer and Hercules NEO ultra-fast gas phase electronic nose for analysis. High performance liquid chromatography was employed to determine the content of calycosin, calycosin-7-glucoside, formononetin, and ononin in the Astragali Radix decoction pieces processed with honey to different degrees. Multivariate statistical analyses including partial least squares-discriminant analysis(PLS-DA), orthogonal partial least squares-discriminant analysis(OPLS-DA), differential factor analysis(DFA), and Bayesian discriminant analysis were adopted to differentiate the Astragali Radix decoction pieces processed with honey to different degrees and evaluate the correlations between visual characteristics and chemical composition.

Developing the analytical procedure requires estimating what independent variables will be tested and at what levels. There are statistical models that enable the optimization of the process. They involve statistical analysis, which indicates the crucial factors for the process and the potential interactions between the analyzed variables.

The detection and classification of foodborne pathogenic bacteria is crucial for food safety monitoring, consequently requiring rapid, accurate and sensitive methods. In this study, the surface-enhanced Raman spectroscopy (SERS) technique coupled with chemometrics methods was used to detect and classify six kinds of foodborne pathogenic bacteria, including (. ), (.
