Kavli Affiliate: L. Mahadevan | First 5 Authors: F. Mori, L. Mahadevan, , , | Summary: Inspired by the intermittent reorientation strategy seen in the behavior of the dung beetle, we consider the problem of the navigation strategy of an active Brownian particle moving in two dimensions. We assume that the heading of the particle […]
Kavli Affiliate: James Bock | First 5 Authors: Samuel S. Condon, Stephen Padin, James Bock, Howard Hui, Phillip Korngut | Summary: We describe a technique for measuring focus errors in a cryogenic, wide-field, near-infrared space telescope. The measurements are made with a collimator looking through a large vacuum window, with a reflective cold filter to […]
Kavli Affiliate: Anton R. Akhmerov | First 5 Authors: Isidora Araya Day, Kostas Vilkelis, Antonio L. R. Manesco, A. Mert Bozkurt, Valla Fatemi | Summary: We demonstrate that Andreev modes that propagate along a transparent Josephson junction have a perfect transmission at the point where three junctions meet. The chirality and the number of quantized […]
Kavli Affiliate: Srijit Goswami | First 5 Authors: Christian G. Prosko, Wietze D. Huisman, Ivan Kulesh, Di Xiao, Candice Thomas | Summary: We study a phase-tunable four-terminal Josephson junction formed in an InSbAs two-dimensional electron gas proximitized by aluminum. By embedding the two pairs of junction terminals in asymmetric DC SQUIDs we can control the […]
Kavli Affiliate: L. Mahadevan | First 5 Authors: Sumit Sinha, Vishaal Krishnan, L Mahadevan, , | Summary: Active many-body systems composed of many interacting degrees of freedom often operate out of equilibrium, giving rise to non-trivial emergent behaviors which can be functional in both evolved and engineered contexts. This naturally suggests the question of control […]
Kavli Affiliate: Wei Gao | First 5 Authors: [#item_custom_name[1]], [#item_custom_name[2]], [#item_custom_name[3]], [#item_custom_name[4]], [#item_custom_name[5]] | Summary: Occlusions between consecutive frames have long posed a significant challenge in optical flow estimation. The inherent ambiguity introduced by occlusions directly violates the brightness constancy constraint and considerably hinders pixel-to-pixel matching. To address this issue, multi-frame optical flow methods leverage […]
Kavli Affiliate: Ting Xu | First 5 Authors: Qiangbo Zhang, Peicheng Lin, Chang Wang, Yang Zhang, Zeqing Yu | Summary: As the realm of spectral imaging applications extends its reach into the domains of mobile technology and augmented reality, the demands for compact yet high-fidelity systems become increasingly pronounced. Conventional methodologies, exemplified by coded aperture […]
Kavli Affiliate: Wei Gao | First 5 Authors: , , , , | Summary: Large-scale image-language pretrained models, e.g., CLIP, have demonstrated remarkable proficiency in acquiring general multi-modal knowledge through web-scale image-text data. Despite the impressive performance of image-language models on various image tasks, how to effectively expand them on general video understanding remains an […]
Kavli Affiliate: Feng Wang | First 5 Authors: Yiwen Chen, Zilong Chen, Chi Zhang, Feng Wang, Xiaofeng Yang | Summary: 3D editing plays a crucial role in many areas such as gaming and virtual reality. Traditional 3D editing methods, which rely on representations like meshes and point clouds, often fall short in realistically depicting complex […]
