Kavli Affiliate: Tom Melia | Summary:Motivated by the quantum description of gauge theories, we study the cosmological effects of relaxing the Hamiltonian and momentum constraints in general relativity and Gauss’ law in electromagnetism. We show that the unconstrained theories have new source terms that mimic a pressureless dust and a charge density that only follows […]
Kavli Affiliate: Yishi Jin | Authors: Seungmee Park, Nathaniel Noblett, Lauren Pitts, Antonio Colavita, Ann M Wehman, Yishi Jin and Andrew D Chishol/p> | Summary: Mature neurons maintain their distinctive morphology for extended periods in adult life. Compared to developmental neurite outgrowth, axon guidance, and target selection, relatively little is known of mechanisms that maintain […]
Kavli Affiliate: Loren Frank | Authors: Joshua P Chu, Michael E Coulter, Eric L. Denovellis, Trevor TK Nguyen, Daniel F Liu, Xinyi Deng, Uri T Eden, Caleb T Kemere and Loren M Frank | Summary: Decoding algorithms provide a powerful tool for understanding the firing patterns that underlie cognitive processes such as motor control, learning, […]
Kavli Affiliate: Eliska Greplova | Summary:Contemporary quantum devices are reaching new limits in size and complexity, allowing for the experimental exploration of emergent quantum modes. However, this increased complexity introduces significant challenges in device tuning and control. Here, we demonstrate autonomous tuning of emergent Poor Man’s Majorana zero modes in a minimal realization of a […]
Kavli Affiliate: Richard Kessler | Summary:Differential Chromatic Refraction (DCR) is caused by the wavelength dependence of our atmosphere’s refractive index, which shifts the apparent positions of stars and galaxies and distorts their shapes depending on their spectral energy distributions (SEDs). While this effect is typically mitigated and corrected for in imaging observations, we investigate how […]
Kavli Affiliate: Frank Wilczek | Summary:Postulating the identification of $ψ^*(x, t) ψ(x,t)$ with a physical probability density is unsatisfactory conceptually and overly limited practically. For electrons, there is a simple, calculable relativistic correction proportional to $nabla ψ^* cdot nabla ψ$. In particular, zeroes of the wave function do not indicate vanishing probability density of presence. […]
Kavli Affiliate: Michael Shadlen | Authors: Natalie A Steinemann, Gabriel M Stine, Eric M Trautmann, Ariel Zylberberg, Daniel M Wolpert and Michael N Shadlen | Summary: Neurobiological investigations of perceptual decision-making have furnished the first glimpse of a flexible cognitive process at the level of single neurons (Shadlen and Newsome, 1996; Shadlen and Kiani, 2013). […]
Kavli Affiliate: Zheng Zhu | First 5 Authors: Chen Min, Dawei Zhao, Liang Xiao, Jian Zhao, Xinli Xu | Summary: Vision-centric autonomous driving has recently raised wide attention due to its lower cost. Pre-training is essential for extracting a universal representation. However, current vision-centric pre-training typically relies on either 2D or 3D pre-text tasks, overlooking […]
Kavli Affiliate: Yi Zhou | First 5 Authors: Mayank Mishra, Matt Stallone, Gaoyuan Zhang, Yikang Shen, Aditya Prasad | Summary: Large Language Models (LLMs) trained on code are revolutionizing the software development process. Increasingly, code LLMs are being integrated into software development environments to improve the productivity of human programmers, and LLM-based agents are beginning […]
Kavli Affiliate: Luis C. Ho | First 5 Authors: Wancheng Xu, Lang Cui, Xiang Liu, Tao An, Hongmin Cao | Summary: It is believed that dual active galactic nuclei (dual AGN) will form during galaxies merge. Studying dual-AGN emission can provide valuable insights into galaxy merging and evolution. To investigate parsec-scale radio emission properties, we […]
