FPM-INR: Fourier ptychographic microscopy image stack reconstruction using implicit neural representations

Kavli Affiliate: Changhuei Yang | First 5 Authors: Haowen Zhou, Brandon Y. Feng, Haiyun Guo, Siyu Lin, Mingshu Liang | Summary: Image stacks provide invaluable 3D information in various biological and pathological imaging applications. Fourier ptychographic microscopy (FPM) enables reconstructing high-resolution, wide field-of-view image stacks without z-stack scanning, thus significantly accelerating image acquisition. However, existing […]

WSDMS: Debunk Fake News via Weakly Supervised Detection of Misinforming Sentences with Contextualized Social Wisdom

Kavli Affiliate: Wei Gao | First 5 Authors: Ruichao Yang, Wei Gao, Jing Ma, Hongzhan Lin, Zhiwei Yang | Summary: In recent years, we witness the explosion of false and unconfirmed information (i.e., rumors) that went viral on social media and shocked the public. Rumors can trigger versatile, mostly controversial stance expressions among social media […]

Laser-driven ultrafast impedance spectroscopy for measuring complex ion hopping processes

Kavli Affiliate: Scott K. Cushing | First 5 Authors: Kim H. Pham, Scott K. Cushing, , , | Summary: Superionic conductors, or solid-state ion-conductors that surpass 0.01 S/cm in conductivity, can enable more energy dense batteries, robust artificial ion pumps, and optimized fuel cells. However, tailoring superionic conductors require precise knowledge of ion migration mechanisms […]
