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: Michael Wimmer | First 5 Authors: David van Driel, Rouven Koch, Vincent P. M. Sietses, Sebastiaan L. D. ten Haaf, Chun-Xiao Liu | 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 […]
Kavli Affiliate: Andrey Kravtsov | First 5 Authors: Andrey Kravtsov, Vasily Belokurov, , , | Summary: We use a well-motivated galaxy formation framework to predict stellar masses, star formation rates (SFR), and ultraviolet (UV) luminosities of galaxy populations at redshifts $zin 5-16$, taking into account stochasticity of SFR in a controlled manner. We demonstrate that […]
Kavli Affiliate: Richard Kessler | First 5 Authors: Jaemyoung Jason Lee, Masao Sako, Richard Kessler, Alex I. Malz, The LSST Dark Energy Science Collaboration | 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 […]
Kavli Affiliate: Richard Kessler | First 5 Authors: Jaemyoung, Lee, Masao Sako, Richard Kessler, Alex I. Malz | 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 […]
Kavli Affiliate: Frank Wilczek | First 5 Authors: Frank Wilczek, Zara Yu, , , | Summary: Postulating the identification of $psi^*(x, t) psi(x,t)$ with a physical probability density is unsatisfactory conceptually and overly limited practically. For electrons, there is a simple, calculable relativistic correction proportional to $nabla psi^* cdot nabla psi$. In particular, zeroes of […]

Kavli Affiliate: Frank Wilczek | First 5 Authors: Frank Wilczek, , , , | Summary: If we consider a cat to be an isolated mechanical system governed by T-invariant mechanics, then its ability to land on its feet after being released from rest is incomprehensible. It is more appropriate to treat the cat as a […]
Kavli Affiliate: Max Tegmark | First 5 Authors: Subhash Kantamneni, Ziming Liu, Max Tegmark, , | Summary: Integrable partial differential equation (PDE) systems are of great interest in natural science, but are exceedingly rare and difficult to discover. To solve this, we introduce OptPDE, a first-of-its-kind machine learning approach that Optimizes PDEs’ coefficients to maximize […]
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).
