Cancerous cells’ identity is determined via a mixture of multiple factors such as genomic variations, epigenetics, and the regulatory variations that are involved in transcription. The differences in transcriptome expression as well as abnormal structures in peptides determine phenotypical differences.

Research findings have demonstrated a statistically significant negative correlation between profitability, growth, and liquidity and the capital structure measured by the debt ratio. Although it also decreases with non-debt tax shields, this variable does not have statistical meaning with the dependent variable. Size is the only variable with a positive correlation coefficient, but no statistical significance was found either. The results of the study can help these firms build a reasonable capital structure to enhance their intrinsic value.

In this report, SYGO:Eu3+ red phosphor have been successfully synthesized by sol-gel method. The X-ray diffraction results show that the sample has a cubic crystal structure, belonging to the space group Ia3d (230) without any doping. Scanning electron microscopy (FE-SEM) combined with EDS was performed to determine the microstructure and elemental composition of the fabricated phosphor.

This paper presents a simulation method to determine the local sensitivity of geometrical parameters of the micro-beam models used in the micro-mechanical structures. The analysis allows for defining the essential parameters in designing the microstructures to reduce the designing time. The analysis results can be used to give suitable geometrical parameters for the micro-mechanical structure according to the purposed resonant frequency.

The objective of this study is to explore critical success factors (CSFs) influencing AI adoption and evaluate their importance level in banking sectors using the fuzzy AHP. First, a conceptual framework based on TOEH (Technology - Organization - Environment - Human) theory was utilize to identify the CSFs influencing AI adoption in the context of Vietnamese bank sector. After this step, a specific hierarchic structure was identified considering 15 sub-criteria along with four criteria.

A magnetic molecularly imprinted electrochemical sensor was developed for selective determination of sufentanil (SUF) based on carbon paste electrode (CPE) modified with methacrylic acid-ethylene glycol dimethacrylate-coated Fe3O4 nanoparticles (Fe3O4@MAA-EGDMA NPs). The structural properties, chemical structure, and electrochemical behaviors of the imprinted sensor were characterized by X-ray diffraction analysis (XRD), Fourier transform infrared spectroscopy (FT-IR), and square wave voltammetry (SWV), respectively.
