Kavli Affiliate: Matthew Fisher | First 5 Authors: James Hong, Lu Yuan, Michaël Gharbi, Matthew Fisher, Kayvon Fatahalian | Summary: How to frame (or crop) a photo often depends on the image subject and its context; e.g., a human portrait. Recent works have defined the subject-aware image cropping task as a nuanced and practical version […]
Kavli Affiliate: Matthew Fisher | First 5 Authors: Vikas Thamizharasan, Difan Liu, Shantanu Agarwal, Matthew Fisher, Michael Gharbi | Summary: We present VecFusion, a new neural architecture that can generate vector fonts with varying topological structures and precise control point positions. Our approach is a cascaded diffusion model which consists of a raster diffusion model […]
Kavli Affiliate: David Gross | First 5 Authors: David Gross, Dominik Hangleiter, , , | Summary: Quantum computing devices can now perform sampling tasks which, according to complexity-theoretic and numerical evidence, are beyond the reach of classical computers. This raises the question of how one can efficiently verify that a quantum computer operating in this […]
Kavli Affiliate: Lars Bildsten | First 5 Authors: Corey W. Bradshaw, Matti Dorsch, Thomas Kupfer, Brad N. Barlow, Uli Heber | Summary: Blue large-amplitude pulsators (BLAPs) make up a rare class of hot pulsating stars with effective temperatures of $approx$30,000 K and surface gravities of 4.0 – 5.0 dex (cgs). The evolutionary origin and current […]
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 […]
