Physical activities can have intrinsic motivational or reinforcing properties.The choice to engage in voluntary physical activity is undertaken in relation to the selection of other alternatives, such as sedentary behaviors, drugs, or food intake.The mesolimbic dopamine (DA) system plays a critical role in behavioral activation or exertion of effor
This paper introduces the technical transformation and system realization of the hoister gap monitoring and Scrimmage Vest protection device in Hongyang No.2 Coal Mine.Through the high-precision laser displacement sensor, we detected displacement signals, such as brake clearance, brake wear value, spring fatigue and brake disc deflection, to conver
Graph contrastive learning (GCL) has attracted extensive research interest due to its powerful ability to capture latent structural and semantic information of graphs in a self-supervised manner.Existing GCL methods commonly adopt predefined graph augmentations to generate two contrastive views.Subsequently, they design a contrastive pretext task b
The clustering of small molecules is of considerable importance for computer-aided drug discovery and virtual screening applications.The structure of chemical data in appropriate subspaces of the chemical space is relevant to sample datasets in a representative manner, to generate small libraries with wide or narrow chemical coverage (depending on
