Polarized X-rays Constrain The Disk-Jet Geometry in a Black Hole X-ray Binary

Kavli Affiliate: Herman L. Marshall | First 5 Authors: Henric Krawczynski, Fabio Muleri, Michal DovĨiak, Alexandra Veledina, Nicole Rodriguez Cavero | Summary: In a black hole X-ray binary (XRB) system, gas accreted from a normal star onto a black hole glows brightly in X-rays. We report on an observation of the XRB Cygnus X-1 (Cyg […]

Pumping the brakes on RNA velocity — understanding and interpreting RNA velocity estimates

Kavli Affiliate: Loyal Goff | Authors: Shijie C. Zheng, Genevieve Stein-O’Brien, Leandros Boukas, Loyal A Goff and Kasper D Hansen | Summary: RNA velocity analysis of single cells promises to predict temporal dynamics from gene expression. Indeed, in many systems, it has been observed that RNA velocity produces a vector field which qualitatively reflects known […]

Shapley-NAS: Discovering Operation Contribution for Neural Architecture Search

Kavli Affiliate: Zheng Zhu | First 5 Authors: Han Xiao, Ziwei Wang, Zheng Zhu, Jie Zhou, Jiwen Lu | Summary: In this paper, we propose a Shapley value based method to evaluate operation contribution (Shapley-NAS) for neural architecture search. Differentiable architecture search (DARTS) acquires the optimal architectures by optimizing the architecture parameters with gradient descent, […]

How Material Heterogeneity Creates Rough Fractures

Kavli Affiliate: Shmuel M. Rubinstein | First 5 Authors: Will Steinhardt, Shmuel M. Rubinstein, , , | Summary: Fractures are a critical process in how materials wear, weaken, and fail whose unpredictable behavior can have dire consequences. While the behavior of smooth cracks in ideal materials is well understood, it is assumed that for real, […]
