Exploring AIGC Video Quality: A Focus on Visual Harmony, Video-Text Consistency and Domain Distribution Gap

Posted by April 21, 2024Caltech

Kavli Affiliate: Wei Gao | First 5 Authors: Bowen Qu, Xiaoyu Liang, Shangkun Sun, Wei Gao, | Summary: The recent advancements in Text-to-Video Artificial Intelligence Generated Content (AIGC) have been remarkable. Compared with traditional videos, the assessment of AIGC videos encounters various challenges: visual inconsistency that defy common sense, discrepancies between content and the textual […]

The representational geometry of emotional states in basolateral amygdala

Posted by klaurent April 21, 2024April 29, 2024Columbia

Kavli Affiliate: Stefano Fusi, Daniel Salzman | Authors: Pia-Kelsey O’Neill, Lorenzo Posani, Jozsef Meszaros, Phebe Warren, Carl E. Schoonover, Andrew J.P. Fink, Stefano Fusi and C. Daniel Salzman | Summary: Sensory stimuli associated with aversive outcomes can cause multiple behavioral responses related to an animal’s evolving emotional state. We employed chemogenetic inactivation and two-photon imaging […]

Transcriptional regulation in the absence of inositol trisphosphate receptor calcium signaling

Posted by dbos April 20, 2024April 29, 2024Rockefeller

Kavli Affiliate: Michael W. Young | Authors: Michael Young, David M Booth, David Smith, Marco Tigano, Gyorgy Hajnoczky and Suresh Joseph | Summary: The activation of IP3 receptor (IP3R) Ca2+ channels generates agonist-mediated Ca2+ signals that regulate a wide range of biological processes. It is therefore surprising that CRISPR induced loss of all three IP3R […]

A Subcortical Feeding Circuit Linking Interoception to Jaw movement

Posted by dbos April 20, 2024April 29, 2024Rockefeller, UCSF

Kavli Affiliate: Jeffrey M. Friedman and Zachary Knight | Authors: Christin Kosse, Jessica Ivanov, Zachary Knight, Kyle Pellegrino and Jeffrey Friedman | Summary: The brain processes an array of stimuli enabling the selection of an appropriate behavioural response but the neural pathways linking interoceptive inputs to outputs for feeding are poorly understood. Here we delineate […]

DMesh: A Differentiable Representation for General Meshes

Posted by dbos April 20, 2024UCAS

Kavli Affiliate: Yi Zhou | First 5 Authors: Sanghyun Son, Matheus Gadelha, Yang Zhou, Zexiang Xu, Ming C. Lin | Summary: We present a differentiable representation, DMesh, for general 3D triangular meshes. DMesh considers both the geometry and connectivity information of a mesh. In our design, we first get a set of convex tetrahedra that […]

Extracting Geometry and Topology of Orange Pericarps for the Design of Bioinspired Energy Absorbing Materials

Posted by April 20, 2024Caltech

Kavli Affiliate: Chiara Daraio | First 5 Authors: Chelsea Fox, Kyle Chen, Micaela Antonini, Tommaso Magrini, Chiara Daraio | Summary: As a result of evolution, many biological materials have developed irregular structures that lead to outstanding mechanical properties, like high stiffness-to-weight ratios and good energy absorption. To reproduce these properties in synthetic materials, biomimicry typically […]

Stacking X-ray Observations of “Little Red Dots”: Implications for their AGN Properties

Posted by dbos April 20, 2024MIT

Kavli Affiliate: Erin Kara | First 5 Authors: Minghao Yue, Anna-Christina Eilers, Tonima Tasnim Ananna, Christos Panagiotou, Erin Kara | Summary: Recent James Webb Space Telescope (JWST) observations have revealed a population of compact extragalactic objects at $zgtrsim4$ with red near-infrared colors, which have been dubbed as “Little Red Dots" (LRDs). The spectroscopically-selected LRDs exhibit […]
