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 […]

V3D: Video Diffusion Models are Effective 3D Generators

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

Kavli Affiliate: Feng Wang | First 5 Authors: Zilong Chen, Yikai Wang, Feng Wang, Zhengyi Wang, Huaping Liu | Summary: Automatic 3D generation has recently attracted widespread attention. Recent methods have greatly accelerated the generation speed, but usually produce less-detailed objects due to limited model capacity or 3D data. Motivated by recent advancements in video […]

How low can you go? Short-read polishing of Oxford Nanopore bacterial genome assemblies

Posted by dbos March 10, 2024March 18, 2024UCSF

Kavli Affiliate: Robert Edwards | Authors: George Bouras, Louise M Judd, Robert A Edwards, Sarah Vreugde, Timothy P. Stinear and Ryan R Wick | Summary: It is now possible to assemble near-perfect bacterial genomes using Oxford Nanopore Technologies (ONT) long reads, but short-read polishing is still required for perfection. However, the effect of short-read depth […]
