A major issue in thermochronology and U-Th-Pb dating is the effect of radiation damage, created by α-recoils from α-decay events, on diffusion radiogenic elements (e.g., He Pb) host mineral. Up until now, thermal events have been considered as only source energy for recovery radiation-damage. However, irradiation, such α-particle event, can itself induce damage recovery. Quantification radiation-induced caused α-particles during has not possible, process at atomic-scale difficult to observe....

With the rapid development of deep learning, automatic defect detection has been introduced into various manufacturing pipelines. Many studies on inspection focus training an accurate model that can perform well a certain type. However, as process evolves, new types may appear in practice. The trained old will struggle to detect ones. To address this issue, we propose use continual lifelong learning for detection. increasingly learn defects yet keeping learned ones non-forgetting without...
