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 […]

Designing transparent conductors using forbidden optical transitions

Posted by klaurent Berkeley

Kavli Affiliate: Kristin A. Persson | Authors: Rachel Woods-Robinson, Yihuang Xiong, Jimmy-Xuan Shen, Nicholas Winner, Matthew K. Horton, Mark Asta, Alex M. Ganose, Geoffroy Hautier, Kristin A. Persson | 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 […]

Visualizing the atomic-scale origin of metallic behavior in Kondo insulators

Posted by klaurent Cornell

Kavli Affiliate: J. C. Seamus Davis | First 5 Authors: Harris Pirie, Eric Mascot, Christian E. Matt, Yu Liu, Pengcheng Chen | Summary: A Kondo lattice is often electrically insulating at low temperatures. However, several recent experiments have detected signatures of bulk metallicity within this Kondo insulating phase. Here we visualize the real-space charge landscape […]

Non-planar snake gaits: from Stigmatic-starts to Sidewinding

Posted by klaurent Harvard

Kavli Affiliate: L. Mahadevan | First 5 Authors: N. Charles, R. Chelakkot, M. Gazzola, B. Young, L. Mahadevan | Summary: Of the vast variety of animal gaits, one of the most striking is the non-planar undulating motion of a sidewinder. But non-planar gaits are not limited to sidewinders. Here we report a new non-planar mode […]

Giant spin Hall effect in AB-stacked MoTe2/WSe2 bilayers

Posted by klaurent Cornell

Kavli Affiliate: Jie Shan | First 5 Authors: Zui Tao, Bowen Shen, Wenjin Zhao, Nai Chao Hu, Tingxin Li | Summary: The spin Hall effect (SHE), in which electrical current generates transverse spin current, plays an important role in spintronics for the generation and manipulation of spin-polarized electrons. The phenomenon originates from spin-orbit coupling. In […]
