Dynamic representation of sound locations during task engagement in marmoset auditory cortex

Kavli Affiliate: Patricia Janak | Shivam Kalhan, Robin Magnard, Yifeng Cheng and Patricia H. Janak | Summary: In auditory cortex, neural responses to stimuli inside receptive fields (RFs) can be further facilitated by behavioral demands, such as attending to a spatial location. It is less clear how off-RF stimuli modulate neural responses and contribute to […]

Uncertainty and reward histories have distinct effects on decisions after wins and losses

Kavli Affiliate: Patricia Janak | Shivam Kalhan, Robin Magnard, Yifeng Cheng and Patricia H. Janak | Summary: Intelligent behavior necessitates an adaptive integration of feedback. It is well-known that animals asymmetrically learn from positive and negative feedback. While asymmetrical learning is a robust behavioral effect, the latent computations behind how animals represent their environments and […]

Observation of stability of Gaussian beams and off-axis beam-cleaning in graded-index media

Kavli Affiliate: Frank W. Wise | First 5 Authors: Varun Sharma, Varun Sharma, , , | Summary: While nonlinear effects in graded-index (GRIN) multimode fibers have been studied extensively, little is known about nonlinear effects in larger GRIN waveguides, where the number of modes approaches infinity and modal dispersion becomes negligible. Here we show that […]

Nonadiabatic force matching for alchemical free-energy estimation

Kavli Affiliate: David T. Limmer | First 5 Authors: Jorge L. Rosa-Raíces, Jorge L. Rosa-Raíces, , , | Summary: We propose a method to compute free-energy differences from nonadiabatic alchemical transformations using flow-based generative models. The method, nonadiabatic force matching, hinges on estimating the dissipation along an alchemical switching process in terms of a nonadiabatic […]

Nonadiabatic force matching for alchemical free-energy estimation

Kavli Affiliate: David T. Limmer | First 5 Authors: Jorge L. Rosa-Raíces, Jorge L. Rosa-Raíces, , , | Summary: We propose a method to compute free energies from nonadiabatic alchemical transformations using diffusion-denoising generative models. The method, nonadiabatic force matching, hinges on estimating — rather than minimizing — the dissipation along an alchemical transition as […]

Fast, low noise CCD systems for future strategic x-ray missions

Kavli Affiliate: Marshall W. Bautz | First 5 Authors: Haley R. Stueber, Haley R. Stueber, , , | Summary: Future strategic X-ray missions, such as the Advanced X-ray Imaging Satellite (AXIS) and those targeted by the Great Observatories Maturation Program (GOMaP), require fast, low-noise X-ray imaging spectrometers. To achieve the speed and noise capabilities required […]
