Summary: The optical properties of the symmetric salamo-like chemical probe (H2CS) of Cu2+ were investigated and fluorescence quenching was observed. The binding constant and LOD of Cu2+ to the H2CS sensor were calculated, and significant changes in the UV-Vis spectra were observed when Cu2+ ions were added. The fluorescence shutdown phenomenon was achieved by adding EDTA to the H2CS-Cu2+ solution.

Summary: Metabolomics has become a pivotal approach for analyzing metabolites in biological systems, allowing for a deeper understanding of the relationship between biochemical processes and physiological conditions. Targeted and untargeted mass spectrometry methods are commonly used, with data-dependent acquisition (DDA) offering the potential for improved metabolite assignment in untargeted metabolomics. However, DDA settings are more complex and prone to errors compared to data-independent acquisition (DIA).

Summary: Feature selection plays a vital role in reducing dimensionality in the quantitative analysis of high-dimensional data. This paper proposes a variable selection method called Mutual Information-Variance Inflation Factor (MI-VIF) that combines mutual information (MI) and the variance inflation factor (VIF). By maximizing the correlation between the independent variable and the response variable and minimizing multicollinearity, MI-VIF achieves effective feature selection.
