Abstract: A core detection device of a coring instrument includes a base body and a core switch mechanism provided on the base body. The base body is provided with a core channel communicated with a core barrel. The core switch mechanism includes a detection portion, a connecting rod assembly and a travel switch which are sequentially arranged and connected along a length direction of the coring instrument. The detection portion is rotatably installed on the base body and one end thereof is extended into the core channel, so that a core passing through the core channel pushes the detection portion to rotate. The connecting rod assembly can be pulled by the rotating detection portion to trigger the travel switch to operate. The core switch mechanism adopts a slider-connecting rod structure, and the kinematic pairs are mainly a sliding pair and a rotating pair.

Abstract: Systems, apparatuses, methods, and computer program products are disclosed for generating a single-index model (SIM) tree. An example method includes receiving a data set and a maximum tree depth. The example method further includes screening a set of variables from the data set to form split variables.

Abstract: The present disclosure provides a consistency evaluation method for a traditional extraction process and a modern extraction process of a traditional Chinese medicine (TCM) compound preparation. In the present disclosure, the reference correlation degree is calculated based on the relative deviation. The reference correlation degree is within a threshold interval of [??, 1]. If the relative deviation is 0, the reference correlation degree is 100%, and at the moment, the quality of a modern extraction sample is completely consistent with that of a reference sample. Thus, compared with the relative deviation, the reference correlation degree can represent a quality difference between the modern extraction sample and the reference sample more intuitively and clearly.
