Abstract: A method for designing polymers includes translating polymer representations of a training dataset and a test dataset into a format comprehensible by a generative pretraining transformer (GPT)-based model, training the GPT-based model with the translated polymer representations, generating new polymer representations, in a predefined format, using the trained GPT-based model, predicting at least one property of the generated new polymer representations using a machine learning (ML) property predictive model and selecting a first subset of the generated new polymer representations as a function of the at least one predicted property, and calculating the at least one property of the first subset of the generated new polymer representations using a molecular dynamics (MD) module.

Abstract: A reinforcement learning system for predicting a doped crystalline material and learning a doping policy for a dopant includes a processor and a memory communicably coupled to the processor. The memory has stored machine-readable instructions that, when executed by the processor, cause the processor to: i) dope a crystal graph representation for a crystalline material (crystal) with dopant atoms; ii) determine a state of the doped crystal; iii) move at least one of the dopant atoms along an edge of the crystal per a doping policy; iv) determine another state of the doped crystal and a reward accumulation of moving the at least one dopant atoms; v) update the doping policy; and repeat steps iii-v for a predetermined number of cycles.

Abstract: A tea spirit and a method for preparing the same are provided. The method comprises steps crushing tea leaves and soaking the crushed tea leaves in a solvent to obtain a tea suspension; subjecting the tea suspension to distillation under reduced pressure to obtain a tea aroma extract and a remaining tea pulp; filtering the tea pulp to obtain a tea soup, and subjecting the tea soup to concentration under reduced pressure and filtering the tea soup to obtain a filtrate; adsorbing the filtrate with macroporous adsorption resin, then adding food-grade anhydrous alcohol, letting the resultant mixture stand, separating solid from the mixture and drying the solid to obtain a tea theanine extract; and mixing the tea aroma extract and the tea theanine extract with Chinese baijiu to obtain the tea wine. The tea wine as obtained has both tea aroma and wine aroma, and also has an improved intoxication tolerance time.
