Abstract: Radical cascade reactions enabling sequence-controlled ring-closing polymerization and ring-opening polymerization for the controlled synthesis of polymers with complex main-chain structures are provided. Facile syntheses leading to low-strain macrocyclic monomers consisting of the ring-opening triggers and extended main-chain structures are also provided. The present disclosure further provides methods for excellent control over polymer molecular weights and molecular weight distributions and high chain-end fidelity allows for the preparation of polymeric systems with well-defined architectures. Further provided are the general nature of the radical cascade-triggered transformations in polymer chemistry, and its application to the synthesis of polymers with diverse main-chain structural motifs with tailored functions.

Abstract: A method for detecting word line shorts in a memory device includes: determining a region of interest (ROI) region in a bright voltage contrast (BVC) image for contact through-holes (CTs) of word lines in the memory device, the CTs comprising first CTs in at least one first word line that is electronically charged and second CTs in at least one second word line that is not electronically charged, and the ROI region comprising the at least one first word line; determining coordinates of each CT in the ROI region; reviewing a grayscale value at a position of the coordinates of each CT in the ROI region to determine whether the CT is a defective CT; and displaying the defective CT in response to the defective CT being determined.

Abstract: A method of determining coordinates of contact through-holes (CTs) in a memory device includes: obtaining a bright voltage contrast (BVC) image including a plurality of CTs in the memory device; converting color components in the BVC image into grayscale values to obtain a grayscale BVC image; performing a dilation process on the grayscale BVC image to obtain a dilated grayscale BVC image; calculating a first threshold for the dilated grayscale BVC image and determining whether the first threshold is greater than or equal to a pre-determined value; in response to the first threshold being greater than or equal to the pre-determined value, performing a first image process on the dilated grayscale BVC image to obtain coordinates of each CT; and in response to the first threshold being smaller than the pre-determined value, performing a second image process on the dilated grayscale BVC image to obtain the coordinates of each CT.

Abstract: A method of locating contact through-hole (CT) positions in a memory device includes: obtaining a bright voltage contrast (BVC) image including a plurality of CTs in the memory device; determining CT coordinates in the BVC image; validating the CT coordinates in the BVC image based on a golden CT layout to obtain validated CT coordinates in the BVC image; and locating the CT positions in the memory device based on the validated CT coordinates in the BVC image.

Abstract: A method, a device and a terminal for generating training data is provided. The method for generating training data includes: obtaining an original image; determining a transferred image based on the image style transfer model and the original image, wherein the image style transfer model is obtained by minimizing a loss function, the loss function is determined by the original loss function the background loss function and the foreground loss function; determining the training data based on the transferred image. The difference between the generated training data and the target image is small, thereby improving the accuracy of the training model obtained by using the training data.

Abstract: The current invent relates to the construction and application of a three-line breeding system in the bay scallop×Peruvian scallop hybrids. The said three-line consists of a male sterile line, a maintainer line and a restorer line. A combination of male sterile line and maintainer line is obtained by continuously backcrossing the male sterile individuals selected from F1 inter-specific hybrid families with sperm of the selfing family of the sperm-providing Peruvian scallops until the progenies are all male sterile. The restorer line is obtained by continuously backcrossing selected individuals from the male sterile line with sperm of the selfing family of a Peruvian scallop until the progenies are all hermaphroditic and exhibit excellent production traits. Commercial male sterile brood stocks are produced by backcrossing the male sterile line with the maintainer line and commercial hybrid spats are produced by backcrossing the male sterile line and the restorer line.
