Agents living in volatile environments must be able to detect changes in contingencies while refraining to adapt to unexpected events that are caused by noise.In Reinforcement Learning (RL) frameworks, this requires learning rates that adapt to past reliability of the model.The observation that behavioural flexibility in animals tends to decrease f
A 75-year-old man was diagnosed with gastric 5 Piece Queen Crossbuck Panel Bedroom cancer.Fifty years previously, he had undergone gastroenterostomy with a Braun enteroenterostomy.At present, a distal gastrectomy and small intestinal partial resection were performed.Intraoperatively, the tumor was localized to the previous stomal site.HE staining s
The statistical characteristics of precipitation play important roles not only in flood and drought risk assessments but also in water resource management.This paper implements a statistical analysis to study the spatial and temporal variability in precipitation in the upper Occasion Dresses reaches of the Hongshui River basin (UHRB), southwestern
Early diagenetic chert serves as a critical archive of life on Earth, yet the mechanisms of chert formation and diagenesis remain uncertain.The present research deciphers chert formation and recrystallization through petrographic observations of Proterozoic microfossiliferous chert and explores its relationship to microfossil preservation.Petrograp
