In recent years, carbon‐based quantum dots as luminophores and co‐reactants have aroused broad interest for their ability to function in electrochemiluminescence (ECL) sensors due to their unique features, including excellent biocompatibility, low toxicity, and water solubility. In this mini review, the synthesis methods of carbon‐based quantum dots are firstly introduced. Then, the mechanism of carbon‐based...
Recent studies established that making concurrent judgments of learning (JOLs) can significantly alter (typically enhance) memory itself—a reactivity effect. The current study recruited 190 Chinese children (Mage = 8.68 years; 101 female) in 2020 and 2021 to explore the reactivity effect on children's learning, its developmental trajectory and associated metacognitive awareness. The results showed...
Fault diagnosis of centrifugal pumps is critical to lower its operating and maintenance costs. Due to the non-stationary and non-linear characteristics of vibration signals of centrifugal pumps, a large number of approaches for feature extraction and fault classification have been developed. However, these traditional methods spend too much time extracting features, reducing feature dimension and...
To improve the robustness of performance assessment for aileron actuators, a novel performance assessment for aileron actuators using multi-fractal detrended fluctuation analysis (MF-DFA) and self-organizing mapping (SOM) neural network is first proposed. First, a generalized regression neural network (GRNN) is employed to establish a fault observer, then the residue is generated by subtracting the...
