DILC-ESAE: Data-Info envelope stacked autoencoder on correlation among samples rather than themselves.

Stacked autoencoders (SAEs) are a powerful and popular tool for structured classification. However, the existing AEs have a common shortcoming: they only focus on the original sample individual without considering the correlation information between similar samples. In fact, the information can significantly enhance the separability, thereby further improving the classification performance.

[Protective effects of 5-n-alkylresorcinols on H_2O_2-induced oxidative damage in Caco-2 cells].

Objective: To investigate the protective effects of five alkylresorcinol homologs on hydrogen peroxide(H_2O_2)-induced oxidative damage in human colorectal adenocarcinoma cells(Caco-2).

Methods: The H_2O_2-induced oxidative damage of Caco-2 cells was used as a model, and the survival rate of Caco-2 cells pretreated with different concentrations(0-80 μmol/L)of 5-n-alkylresorcinols was determined to determine the optimal concentration range. The protective effects of 5-n-alkylresorcinols on oxidative-damaged cells was evaluated by measuring the levels of reactive oxygen species(ROS), malondialdehyde(MDA), glutathione peroxidase(GSH-Px), superoxide dismutase(SOD) and catalase(CAT) activities.

Insulator Abnormal Condition Detection from Small Data Samples.

Insulators are an important part of transmission lines in active distribution networks, and their performance has an impact on the power system's normal operation, security, and dependability. Traditional insulator detection methods, on the other hand, necessitate a significant amount of labor and material resources, necessitating the development of a new detection method to substitute manpower. This paper investigates the abnormal condition detection of insulators based on UAV vision sensors using artificial intelligence algorithms from small samples.

In-situ synthesis of magnetic iron-chitosan-derived biochar as an efficient persulfate activator for phenol degradation.

Persulfate activation is a forceful method for eliminating organic pollutants from coal chemical wastewater. In this study, an in-situ synthesis method was used to fabricate an iron-chitosan-derived biochar (Fe-CS@BC) nanocomposite catalyst using chitosan as a template. Fe was successfully imprinted into the newly synthesized catalyst.

A Novel Functionalized MoS-Based Coating for Efficient Solar Desalination.

Molybdenum disulfide (MoS) has emerged as a promising photothermal material for solar desalination. However, its limitation in integrating with organic substances constrains its application because of the lack of functional groups on its surface. Here, this work presents a functionalization approach to introduce three different functional groups (-COOH -OH -NH) on the surface of MoS by combining them with S vacancies.

Chitin-derived biochar with nitrogen doping to activate persulfate for phenol degradation: Application potential and electron transfer pathway in system.

The fast and efficient removal of organic pollutants (e.g., phenolics) remains one of the focus problems in environment pollution.

Preparation and characterization of lauric acid-stearic acid/expanded perlite as a composite phase change material.

Rapid energy consumption stimulates the development of energy-saving materials. In this work, the L-S eutectic mixture used as a PCM was compounded with EP vacuum adsorption to synthesize LS/EP CPCM. The maximum mass adsorption rate of EP on L-S is determined to be 70% leakage experiments.

Thermal Properties and Reliabilities of Lauric Acid-Based Binary Eutectic Fatty Acid as a Phase Change Material for Building Energy Conservation.

Thermal properties, stability, and reliability of lauric acid-based binary eutectic mixtures for building energy efficiency were studied. The eutectic points and phase change performance of these binary PCMs were obtained as follows: (1) For lauric acid-myristic acid, the mass eutectic point is 70 wt % LA/30 wt % MA. (2) For lauric acid-palmitic acid, the eutectic point is 79 wt % LA/21 wt % PA.

Thermal properties and reliabilities of myristic acid-paraffin wax binary eutectic mixture as a phase change material for solar energy storage.

In this work, a myristic acid (MA)-paraffin wax (PW) binary eutectic phase change material (PCM) was prepared by a melt-solution blending method. The eutectic point of the MA-PW binary system was determined to be 62 wt% MA-38 wt% PW using a cooling curve. In addition, the phase transition properties and thermal stability of MA-PW binary eutectic PCM were investigated by differential scanning calorimetry (DSC) and thermogravimetry (TG) analysis.

The elucidation of surrounding alginate gels on the pollutants degradation by entrapped nanoscale zero-valent iron.

The adsorption capacity of calcium alginate (Ca-alginate) beads was evaluated by measuring the removal of three organic compounds with different charges (malachite green, p-chlophenol and methyl orange). The diffusion was investigated in Ca-alginate hydrogel as a function of solute charge. It was found that an increased electrostatic attraction between the hydrogel and solute would improve the mobility of solute and hence enhance its adsorption efficiency.
