Kavli Affiliate: Boris I. Shraiman | First 5 Authors: Nikolas H. Claussen, Fridtjof Brauns, Boris I. Shraiman, , | Summary: Epithelial tissue elongation by convergent extension is a key motif of animal morphogenesis. On a coarse scale, cell motion resembles laminar fluid flow; yet in contrast to a fluid, epithelial cells adhere to each other […]

Kavli Affiliate: Matthew Fisher | First 5 Authors: Manuel Ladron de Guevara, Matthew Fisher, Aaron Hertzmann, , | Summary: We introduce a novel image-to-painting method that facilitates the creation of large-scale, high-fidelity paintings with human-like quality and stylistic variation. To process large images and gain control over the painting process, we introduce a segmentation-based painting […]
Kavli Affiliate: Lars Bildsten | First 5 Authors: Tin Long Sunny Wong, Lars Bildsten, , , | Summary: RCB stars are $Lapprox10^4,L_{odot}$ solar-mass objects that can exhibit large periods of extinction from dust ejection episodes. Many exhibit semiregular pulsations in the range of $30-50$ days with semi-amplitudes of $0.05-0.3$ magnitude. Space-based photometry has discovered that […]
Kavli Affiliate: David Gross | First 5 Authors: Sabrina Ammann, Maximilian Hess, Debora Ramacciotti, Sándor P. Fekete, Paulina L. A. Goedicke | Summary: In recent years, strong expectations have been raised for the possible power of quantum computing for solving difficult optimization problems, based on theoretical, asymptotic worst-case bounds. Can we expect this to have […]
Kavli Affiliate: Lars Bildsten | First 5 Authors: Logan J. Prust, Lars Bildsten, , , | Summary: Stars and planets move supersonically in a gaseous medium during planetary engulfment, stellar interactions and within protoplanetary disks. For a nearly uniform medium, the relevant parameters are the Mach number and the size of the body, $R$, relative […]
Kavli Affiliate: Matthew Fisher | First 5 Authors: Arman Maesumi, Paul Guerrero, Vladimir G. Kim, Matthew Fisher, Siddhartha Chaudhuri | Summary: Exploring variations of 3D shapes is a time-consuming process in traditional 3D modeling tools. Deep generative models of 3D shapes often feature continuous latent spaces that can, in principle, be used to explore potential […]
Kavli Affiliate: Leon Balents | First 5 Authors: Takamori Park, Leon Balents, , , | Summary: Inspired by the recent work by Delacretaz et. al., we rigorously derive an exact and simple method to bosonize a non-interacting fermionic system with a Fermi surface starting from a microscopic Hamiltonian. In the long-wavelength limit, we show that […]

Kavli Affiliate: Lars Bildsten | First 5 Authors: Joel C. Zinn, Marc H. Pinsonneault, Lars Bildsten, Dennis Stello, | Summary: Although stellar radii from asteroseismic scaling relations agree at the percent level with independent estimates for main sequence and most first-ascent red giant branch stars, the scaling relations over-predict radii at the tens of percent […]
