Production of Ammonia Makes Venusian Clouds Habitable and Explains Observed Cloud-Level Chemical Anomalies

Kavli Affiliate: Sara Seager | First 5 Authors: William Bains, Janusz J. Petkowski, Paul B. Rimmer, Sara Seager, | Summary: The atmosphere of Venus remains mysterious, with many outstanding chemical connundra. These include: the unexpected presence of ~10 ppm O2 in the cloud layers; an unknown composition of large particles in the lower cloud layers; […]

Covariance matrices for variance-suppressed simulations

Kavli Affiliate: Risa H. Wechsler | First 5 Authors: Tony Zhang, Chia-Hsun Chuang, Risa H. Wechsler, Shadab Alam, Joseph DeRose | Summary: Cosmological $N$-body simulations provide numerical predictions of the structure of the universe against which to compare data from ongoing and future surveys. The growing volume of the surveyed universe, however, requires increasingly large […]

Gravitationally Mediated Entanglement: Newtonian Field vs. Gravitons

Kavli Affiliate: Robert M. Wald | First 5 Authors: Daine L. Danielson, Gautam Satishchandran, Robert M. Wald, , | Summary: We argue that if the Newtonian gravitational field of a body can mediate entanglement with another body, then it should also be possible for the body producing the Newtonian field to entangle directly with on-shell […]

Deep XMM-Newton Observations of an X-ray Weak, Broad Absorption Line Quasar at $z=6.5$

Kavli Affiliate: Ran Wang | First 5 Authors: Jinyi Yang, Xiaohui Fan, Feige Wang, Giorgio Lanzuisi, Riccardo Nanni | Summary: We report X-ray observations of the most distant known gravitationally lensed quasar, J0439+1634 at $z=6.52$, which is also a broad absorption line (BAL) quasar, using the XMM-Newton Observatory. With a 130 ks exposure, the quasar […]

HyperSegNAS: Bridging One-Shot Neural Architecture Search with 3D Medical Image Segmentation using HyperNet

Kavli Affiliate: Cheng Peng | First 5 Authors: Cheng Peng, Andriy Myronenko, Ali Hatamizadeh, Vish Nath, Md Mahfuzur Rahman Siddiquee | Summary: Semantic segmentation of 3D medical images is a challenging task due to the high variability of the shape and pattern of objects (such as organs or tumors). Given the recent success of deep […]
