Real-Time Ferrogram Segmentation of Wear Debris Using Multi-Level Feature Reused Unet.

The real-time monitoring and fault diagnosis of modern machinery and equipment impose higher demands on equipment maintenance, with the extraction of morphological characteristics of wear debris in lubricating oil emerging as a critical approach for real-time monitoring of wear, holding significant importance in the field. The online visual ferrograph (OLVF) technique serves as a representative method in this study. Various semantic segmentation approaches, such as DeepLabV3+, PSPNet, Segformer, Unet, and other models, are employed to process the oil wear particle image for conducting comparative experiments.

Primer Exchange Reaction Coupled with DNA-Templated Silver Nanoclusters for Label-Free and Sensitive Detection of MicroRNA.

MicroRNAs (MiRNAs) play pivotal roles in regulating gene expression, and serve as crucial biomarkers for diagnosis of a variety of disease. However, label-free and sensitive miRNA detection remains a huge challenge due to the low abundance. Herein, we developed an approach through integrating primer exchange reaction (PER) with DNA-templated silver nanoclusters (AgNCs) for label-free and sensitive miRNA detection.

Toxicity of nickel and cobalt in Japanese flounder.

Nickel and cobalt are essential elements that become toxic at high concentrations. Little is known about nickel and cobalt toxicity in aquatic animals. This study aimed to investigate acute and chronic toxicity of nickel and cobalt in Japanese flounder (Paralichthys olivaceous), with emphasis on oxidative stress reactions, histopathological changes, and differences in gene expression.

Influence of Alloy Substrate Treatment on Microstructure and Surface Performances of Arc-Ion Plated Gold-Like Film.

Three typical surface pretreatment strategies (grind, drawing, polishing) are employed to explore the influence of alloy substrate treatment on microstructure and surface performances of arc-ion plated TiN and ZrN films. The luminance and color of the films are measured by the color coordinate value of CIELab system (a color system which is defined by the International Commission on illumination). The crystal phases, morphology and microstructure are characterized and analyzed by scanning electron microscope (SEM) and X-ray powder diffraction (XRD).

Effects of sodium houttuyfonate on phosphorylation of CaMK II, CREB and ERK 1/2 and expression of c-Fos in macrophages.

The purpose of this research is to investigate the effects of sodium houttuyfonate on the phosphorylation of CaMK II, CREB and ERK 1/2, and the expression of c-Fos. Macrophages were cultured in vitro with or without sodium houttuyfonate in the culture medium. After cell culture, macrophages were lysed and the lysate of the macrophages was collected for analysis.

[Study on the blood glucose and lipid of soybean milk rich in chromium to diabetic rats].

Unlabelled: To reveal the effects of soybean milk with chromium fortification on the blood glucose and lipid of diabetic rat dealt with alloxan. The alloxan diabetic rats were divided into three groups and were fed continuously with the soybean milk without chromium fortification [Cr 0.25 microgram/(d.

Studies on adjuvanticity of sodium houttuyfonate and its mechanism.

The adjuvanticity of sodium houttuyfonate (SH) and its mechanism were studied in this research. Significant enhancement of antibody production was observed when co-injected with antigen. The levels of anti-BSA antibodies were measured by enzyme-linked immunosorbent assay (ELISA).
