Fractional stochastic vibration system under recycling noise
Published 2023-08-01“…This article uses a fractional modification of the well-known van der Pol oscillator with multiplicative and additive recycling noises as an example to study its stationary response and its stochastic bifurcation. First, based on the principle of the minimum mean square error, the fractional derivative is equivalent to a linear combination of damping and restoring forces, and the original system is simplified into an equivalent integer order system. …”

Error Modeling and Parameter Calibration Method for Industrial Robots Based on 6-DOF Position and Orientation
Published 2023-09-01“…This paper presents a more accurate error model and parameter calibration method for industrial robots based on six degrees-of-freedom position and orientation to identify the actual structural parameters. Firstly, based on the modified Denavit–Hartenberg parameters, the transformation errors of the tool coordinate system and measurement coordinate frame were introduced to establish a geometric parameter error model with positional and orientation accuracy as the optimization objectives. …”

Integrated network pharmacology, metabolomics, transcriptomics and microbiome strategies to reveal the mechanism of Sang Ju Yin on the treatment of acute lung injury on the gut-mic...
Published 2024-03-01“…This study intended to explore the therapeutic material basis and molecular mechanisms of a classical traditional Chinese medicinal prescription, Sang Ju Yin (SJY), against ALI, focusing on the chemical components of formula composition, the disturbance of host genes/metabolites and the dysbiosis of intestinal flora. First, based on liquid chromatography-mass spectrometry (LC-MS) component analysis, 212 in vitro and 44 in vivo compounds were identified respectively in SJY. …”
