Summary: This experimental study investigates the mechanical characteristics of CFRP bars, including their tensile, compressive, and shear strength, as well as modulus of elasticity. Understanding these properties is crucial for analyzing the behavior of concrete structures reinforced with CFRP rebars. The use of a coefficient allows for the prediction of tensile strength based on shear strength. The results confirm that CFRP's tensile strength is influenced by its diameter due to the shear lag effect.

Summary: This study systematically investigates the mechanical properties of controlled low-strength material (CLSM) by manipulating fiber length and doping amount as control variables. The results show that there is a positive correlation between fiber length and material strength within the range of 0-6 mm, as well as a positive correlation between fiber doping and material strength within the range of 0-0.3%. However, the strength of CLSM decreases when fiber doping exceeds 0.3%. SEM and PCAS analyses confirm that the incorporation of fibers effectively reduces the porosity of the material and forms a mesh structure. This study provides valuable insights into optimizing the mechanical properties of CLSM and has important implications for its practical application, especially in terms of enhancing strength through fiber incorporation.

Summary: Liver disease is a major cause of global mortality, and identifying biomarkers for diagnosing its progression is crucial for improving outcomes. Targeted mass spectrometry is a powerful tool for verifying biomarker candidates and clinical applications, particularly for glycoproteins translation. However, the limitation of analyzing only one sample per run has become apparent. In this study, a high-throughput intact N-glycopeptides quantification strategy was developed, allowing the validation of 20 samples per run with an average analysis time of 3 minutes per sample. The strategy was applied in a cohort of 461 serum samples and identified a panel of 10 IgG N-glycopeptides that have strong clinical utility in evaluating the severity of liver disease.
