Electrically Programmable Pixelated Graphene-Integrated Plasmonic Metasurfaces for Coherent Mid-Infrared Emission

Posted by dbos March 11, 2024Peking

Kavli Affiliate: Zhuo Li | First 5 Authors: Xiu Liu, Yibai Zhong, Zexiao Wang, Tianyi Huang, Sen Lin | Summary: Active metasurfaces have recently emerged as compact, lightweight, and efficient platforms for dynamic control of electromagnetic fields and optical responses. However, the complexities associated with their post-fabrication tunability significantly hinder their widespread applications, especially for […]

Firewalls at exponentially late times

Posted by dbos March 11, 2024March 25, 2024Tokyo

Kavli Affiliate: Yasunori Nomura | First 5 Authors: Andreas Blommaert, Chang-Han Chen, Yasunori Nomura, , | Summary: We consider a version of the typical state firewall setup recently reintroduced by Stanford and Yang, who found that wormholes may create firewalls. We examine a late-time double scaling limit in JT gravity in which one can resum […]

Bayesian Diffusion Models for 3D Shape Reconstruction

Posted by dbos March 11, 2024Berkeley

Kavli Affiliate: Xiang Zhang | First 5 Authors: Haiyang Xu, Yu Lei, Zeyuan Chen, Xiang Zhang, Yue Zhao | Summary: We present Bayesian Diffusion Models (BDM), a prediction algorithm that performs effective Bayesian inference by tightly coupling the top-down (prior) information with the bottom-up (data-driven) procedure via joint diffusion processes. We show the effectiveness of […]

Investigating model dependencies for obscured Active Galactic Nuclei: a case study of NGC 3982

Posted by dbos March 11, 2024March 25, 2024Peking

Kavli Affiliate: Claudio Ricci | First 5 Authors: Kristína Kallová, Peter G. Boorman, Claudio Ricci, , | Summary: X-ray spectroscopy of heavily obscured Active Galactic Nuclei (AGN) offers a unique opportunity to study the circum-nuclear environment of accreting supermassive black holes (SMBHs). However, individual models describing the obscurer have unique parameter spaces that give distinct […]

Non-uniform contextual interactions in the visual cortex place fundamental limits on spatial vision

Posted by dbos March 11, 2024March 25, 2024Yale

Kavli Affiliate: Anirvan Nandy | Authors: Mitchell P Morton, Sachira Denagamage, Nyomi V Hudson and Anirvan S Nandy | Summary: A prevailing assumption in our understanding of how neurons in the primary visual cortex (V1) integrate contextual information is that such processes are spatially uniform. Conversely, perceptual phenomena such as visual crowding, the impaired ability […]

Cell type-specific dynamics of prefrontal gamma synchrony during flexible behavior

Posted by dbos March 11, 2024March 25, 2024UCSF

Kavli Affiliate: Vikaas Sohal | Authors: Aarron Justin Phensy, Lara Louise Hagopian and Vikaas Singh Sohal | Summary: The prefrontal cortex (PFC) is required for many cognitive processes that are disrupted in conditions such as schizophrenia. The PFC is composed of neuronal networks which are organized by both local microcircuitry and inter-regional projections, within which […]

DriveDreamer-2: LLM-Enhanced World Models for Diverse Driving Video Generation

Posted by dbos March 11, 2024UCAS

Kavli Affiliate: Zheng Zhu | First 5 Authors: Guosheng Zhao, Xiaofeng Wang, Zheng Zhu, Xinze Chen, Guan Huang | Summary: World models have demonstrated superiority in autonomous driving, particularly in the generation of multi-view driving videos. However, significant challenges still exist in generating customized driving videos. In this paper, we propose DriveDreamer-2, which builds upon […]
