A Prediction Network for Hydraulic Support Pressure Based on Multitimescale Feature Extraction
Mathematical Problems in Engineering, 2022 The roof water hazard has severely weakened the safety of coal mine production. As the most direct data on the state of the roof, the monitoring big data of the hydraulic support is of great importance to coal mine safety.

Increasing leaf hydraulic conductance with transpiration rate minimizes the water potential drawdown from stem to leaf. [PDF]
, 2014 Leaf hydraulic conductance (k leaf) is a central element in the regulation of leaf water balance but the properties of k leaf remain uncertain. Here, the evidence for the following two models for k leaf in well-hydrated plants is evaluated: (i) k leaf is
