Cross-Coupled Sliding Mode Synchronous Control for a Double Lifting Point Hydraulic Hoist.

This paper proposes a sliding mode synchronous control approach to enhance the position synchronization performance and anti-interference capability of a double lifting point hydraulic hoist. Building upon the cross-coupling synchronous control method, a coupling sliding mode surface is formulated, incorporating the single-cylinder following error and double-cylinder synchronization error. Additionally, a sliding mode synchronous controller is devised to ensure the convergence of both the single-cylinder following and synchronization error.

An Empirical Study of Feedforward Control in Unplanned Extubation of Nasogastric Tube.

Objective: To explore the effect of feedforward control on reducing the incidence of unplanned extubation and improving the quality of catheter nursing.

Methods: A total of 186 patients with nasogastric tube after gastrointestinal surgery in the eastern region of our hospital from September 2020 to September 2021 were selected as the control group; 186 patients with nasogastric tube after gastrointestinal surgery in the western region of our hospital at the same period were selected as the experimental group. The influencing factors of unplanned extubation in patients with long-term postoperative nasogastric tube were analyzed, and effective preoperative and postoperative health education was conducted.

miR390-tasiRNA3-ARF4 pathway is involved in regulating flowering time in woodland strawberry.

miR390-tasiRNA3-ARF4 pathway was identified in woodland strawberry. FvemiR390 was involved in the regulation of flowering time, and miR390-tasiRNA3-ARF4 regulated flowering time through FveAP1/FveFUL in woodland strawberry. miRNA is an important type of regulator, and widely involved in plant growth, development and stress response.

Auxin-induced AUXIN RESPONSE FACTOR4 activates APETALA1 and FRUITFULL to promote flowering in woodland strawberry.

Flowering time is known to be regulated by numerous pathways, such as the autonomous, gibberellin, aging, photoperiod-mediated, and vernalization pathways. These regulatory mechanisms involve both environmental triggers and endogenous hormonal cues. Additional flowering control mechanisms mediated by other phytohormones, such as auxin, are less well understood.

An Adaptive Filter for Nonlinear Multi-Sensor Systems with Heavy-Tailed Noise.

Aiming towards state estimation and information fusion for nonlinear systems with heavy-tailed measurement noise, a variational Bayesian Student's t-based cubature information filter (VBST-CIF) is designed. Furthermore, a multi-sensor variational Bayesian Student's t-based cubature information feedback fusion (VBST-CIFF) algorithm is also derived. In the proposed VBST-CIF, the spherical-radial cubature (SRC) rule is embedded into the variational Bayes (VB) method for a joint estimation of states and scale matrix, degree-of-freedom (DOF) parameter, as well as an auxiliary parameter in the nonlinear system with heavy-tailed noise.
