Abstract: A method for predicting epidermal growth factor receptor (EGFR) mutations in lung adenocarcinoma is provided. The method utilizes a lung adenocarcinoma EGFR mutation classification model based on a deep learning model, and performs back-propagation training on the deep learning model by using whole-slide pathological images and corresponding pathological data. The trained lung adenocarcinoma EGFR mutation classification model can determine whether a to-be-classified slide-level image with lung adenocarcinoma features have EGFR mutations.

Abstract: The invention provides a method of preparing a metallization structure on a solar cell. The method includes patterning a first composition on a surface of a semiconductor substrate; and applying a second composition over the first composition. An area covered by the first composition is 5-95% of an area covered by the second composition. The semiconductor substrate is then subjected to firing conditions. The invention also provides a metallization structure formed using the method described herein.
