Machine Learning Identifies Stemness Features Associated with Oncogenic Dedifferentiation

Jia Liu, Jian Wang, Wei Zhang, Jun Li, Min Wang, Wei Li, Hui Shen, Li Ding, Yi Han, Phuong Nguyen

Cancer progression involves the gradual loss of a differentiated phenotype and acquisition of progenitor and stem-cell-like features. Here, we provide novel stemness indices for assessing the degree of oncogenic dedifferentiation. We used an innovative one ...

22% Efficient Dopant-free Interdigitated Back Contact Silicon Solar Cells

Christophe Ballif, Bertrand Yves Paul Paviet-Salomon, Matthieu Despeisse, Mathieu Gérard Boccard, Sihua Zhong, Wenjie Lin, Weiliang Wu, Hui Shen

In this study, we present dopant-free back contact heterojunction silicon solar cells employing MoOx and MgFx based stacks as hole-and electron-selective contacts deposited using a thermal evaporation process at low temperature. Only two masking steps and ...
