APES: Articulated Part Extraction from Sprite Sheets

Posted by klaurent UCSB

Kavli Affiliate: Matthew Fisher | First 5 Authors: Zhan Xu, Matthew Fisher, Yang Zhou, Deepali Aneja, Rushikesh Dudhat | Summary: Rigged puppets are one of the most prevalent representations to create 2D character animations. Creating these puppets requires partitioning characters into independently moving parts. In this work, we present a method to automatically identify such […]

NeMF: Neural Motion Fields for Kinematic Animation

Posted by klaurent UCAS

Kavli Affiliate: Yi Zhou | First 5 Authors: Chengan He, Jun Saito, James Zachary, Holly Rushmeier, Yi Zhou | Summary: We present an implicit neural representation to learn the spatio-temporal space of kinematic motions. Unlike previous work that represents motion as discrete sequential samples, we propose to express the vast motion space as a continuous […]

Recording large-scale, cellular-resolution neuronal activity from freely-moving mice

Posted by klaurent Columbia

Kavli Affiliate: Aniruddha Das | Authors: Aniruddha Das, Sarah Holden, Julie Borovicka, Jacob Icardi, Davina Patel, Rushik Patel, Jacob Raber and Hod Dana | Summary: To date, recording of cellular-resolution activity from awake mice has required either head fixation under a microscope or attaching a miniaturized device to the skull, both of which inevitably affect […]

Anisotropic Gigahertz Antiferromagnetic Resonances of the Easy-Axis van der Waals Antiferromagnet CrSBr

Posted by klaurent Cornell

Kavli Affiliate: Daniel C. Ralph | First 5 Authors: Thow Min Jerald Cham, Saba Karimeddiny, Avalon H. Dismukes, Xavier Roy, Daniel C. Ralph | Summary: We report measurements of antiferromagnetic resonances in the van der Waals easy-axis antiferromagnet CrSBr. The interlayer exchange field and magnetocrystalline anisotropy fields are comparable to laboratory magnetic fields, allowing a […]

Leveraging place field repetition to understand positional versus nonpositional inputs to hippocampal field CA1

Posted by klaurent Hopkins

Kavli Affiliate: James Knierim | Authors: William Hockeimer, Ruo-Yah Lai, Maanasa Natrajan, William Snider and James J. Knierim | Summary: The hippocampus is believed to encode episodic memory by binding information about the content of experience within a spatial framework encoding the location of that experience. Previous work implies a distinction between positional inputs to […]

Viscosity Metamaterials

Posted by klaurent Cornell

Kavli Affiliate: Itai Cohen | First 5 Authors: Prateek Sehgal, Meera Ramaswamy, Edward Y. X. Ong, Christopher Ness, Itai Cohen | Summary: Metamaterials are composite structures whose properties arise from a mesoscale organization of their constituents. Provided this organization occurs on scales smaller than the characteristic lengths associated with their response, it is often possible […]
