Weakly-Supervised Text-driven Contrastive Learning for Facial Behavior Understanding

Posted by klaurent Berkeley

Kavli Affiliate: Xiang Zhang | First 5 Authors: Xiang Zhang, Taoyue Wang, Xiaotian Li, Huiyuan Yang, Lijun Yin | Summary: Contrastive learning has shown promising potential for learning robust representations by utilizing unlabeled data. However, constructing effective positive-negative pairs for contrastive learning on facial behavior datasets remains challenging. This is because such pairs inevitably encode […]

Studying of RNA-protein interactions between a mutant form of glycyl-tRNA synthetase associated with neurodegenerative diseases and IRES type I

Posted by klaurent Rockefeller

Kavli Affiliate: Ekaterina V. Vinogradova | Authors: Ekaterina Vinogradova, Alisa Mikhaylina, Oleg Nikonov and Ekaterina Nikonova | Summary: Aminoacyl-tRNA synthetases (aaRS) are the main enzymes of protein biosynthesis. Human glycyl-tRNA synthetase, in addition to the main function of amino acid transfer to the corresponding tRNA molecules, is also involved in the initiation of IRES I […]

Designing transparent conductors using forbidden optical transitions

Posted by klaurent Berkeley

Kavli Affiliate: Kristin A. Persson | First 5 Authors: Rachel Woods-Robinson, Yihuang Xiong, Jimmy-Xuan Shen, Nicholas Winner, Matthew K. Horton | Summary: Many semiconductors present weak or forbidden transitions at their fundamental band gaps, inducing a widened region of transparency. This occurs in high-performing n-type transparent conductors (TCs) such as Sn-doped In2O3 (ITO), however thus […]
