Large-Scale Crosstalk-Corrected Thermo-Optic Phase Shifter Arrays in Silicon Photonics

Posted by Caltech

Kavli Affiliate: Ali Hajimiri | First 5 Authors: Volkan Gurses, Reza Fatemi, Aroutin Khachaturian, Ali Hajimiri, | Summary: We introduce a thermo-optic phase shifter (TOPS) array architecture with independent phase control of each phase shifter for large-scale and high-density photonic integrated circuits with two different control schemes: pulse amplitude modulation (PAM) and pulse width modulation […]

Spatiotemporal recruitment of inhibition and excitation in the mammalian cortex during electrical stimulation

Posted by klaurent UCSF

Kavli Affiliate: Michael Stryker | Authors: Maria C. Dadarlat, Yujiao Jennifer Sun and Michael P Stryker | Summary: Electrical stimulation has emerged as a powerful and precise treatment in which to modulate aberrant neural activity patterns common in neural dysfunction and disease; however, the physiological process involved in microstimulation is poorly understood, particularly regarding the […]

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 […]
