Abstract: A method of constructing an adaptive multiply accumulate layer in a convolutional neural network, including determining an activation data map width, an activation data map height, a channel depth, a batch, a kernel width, a kernel height and a filter set number, setting a first dimension of an adaptive multiplier layer based on the activation data map width, setting a second dimension of the adaptive multiplier layer based on the channel depth, setting a third dimension of the adaptive multiplier layer based on the filter set number and constructing the adaptive multiplier layer based on the first dimension, the second dimension and the third dimension.

Abstract: A method for rapidly detecting pesticides based on thin-layer chromatography (TLC) and enzyme inhibition principles. The method includes the following steps: cutting a TLC plate into a rectangle, and using one end of the rectangle to contact a sample extract to form a pesticide residue separation area; covering the other end of the rectangle with a small piece cut from filter paper or glass fiber and fixing on a piece of enzyme inhibition reaction test paper to form a pesticide enrichment area; pasting a side of the enzyme inhibition reaction test paper away from the pesticide residue separation area with a piece of filter paper immobilized with a chromogenic agent to form a substrate color development area; and performing color reaction.

Abstract: A burner includes a container provided with a first opening defined for receiving therein alcohol and absorbent securely received in the container to provide stability to the alcohol, a tracking on top of the container and having side walls separated from the side walls of the container so as to compensate deformation of the tracking plate, a sliding plate slidably received on top of the bottom bracket to selectively close the second opening of the tracking plate; and a top plate securely mounted on top of the container to secure the tracking plate and having a third opening in communication with the first opening of the container and the second opening of the tracking plate.
