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 […]
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 […]
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 […]
Kavli Affiliate: Ulrich Sperhake | First 5 Authors: Miren Radia, Ulrich Sperhake, Amelia Drew, Katy Clough, Pau Figueras | Summary: We demonstrate the flexibility and utility of the Berger-Rigoutsos Adaptive Mesh Refinement (AMR) algorithm used in the open-source numerical relativity code GRChombo for generating gravitational waveforms from binary black-hole inspirals, and for studying other problems […]
Kavli Affiliate: Masahiro Kawasaki | First 5 Authors: Masahiro Kawasaki, Kazuyoshi Miyazaki, Kai Murai, Hiromasa Nakatsuka, Eisuke Sonomoto | Summary: Ultra-light axion-like particle (ULAP) with mass $m sim 10^{-22} ~mathrm{eV}$ has recently been attracting attention as a possible solution to the small-scale crisis. ULAP forms quasi-stable objects called oscillons/I-balls, which can survive up to a […]
Kavli Affiliate: Austin J. Minnich | First 5 Authors: Adrian T. K. Tan, Shi-Ning Sun, Ruslan N. Tazhigulov, Garnet Kin-Lic Chan, Austin J. Minnich | Summary: The realization of novel phases of matter on quantum simulators is a topic of intense interest. Digital quantum computers offer a route to prepare topological phases with interactions that […]
Kavli Affiliate: Feng Wang | First 5 Authors: Lianmeng Jiao, Feng Wang, Zhun-ga Liu, Quan Pan, | Summary: As a representative evidential clustering algorithm, evidential c-means (ECM) provides a deeper insight into the data by allowing an object to belong not only to a single class, but also to any subset of a collection of […]
Kavli Affiliate: Feng Wang | First 5 Authors: Lianmeng Jiao, Feng Wang, Zhun-ga Liu, Quan Pan, | Summary: Clustering is widely used in text analysis, natural language processing, image segmentation, and other data mining fields. As a promising clustering algorithm, the evidential c-means (ECM) can provide a deeper insight on the data by allowing an […]
Kavli Affiliate: Anthony Lasenby | First 5 Authors: Michael Hobson, Anthony Lasenby, , , | Summary: We reconsider the status of the so-called second clock effect in Weyl gauge theories of gravity, which are invariant both under local Poincar’e transformations and local changes of scale. In particular, we revisit and extend our previous demonstration that […]
Kavli Affiliate: Peter W. Graham | First 5 Authors: Ariel Arza, Michael A. Fedderke, Peter W. Graham, Derek F. Jackson Kimball, Saarik Kalia | Summary: We demonstrate that ultralight axion dark matter with a coupling to photons induces an oscillating global terrestrial magnetic field signal in the presence of the background geomagnetic field of the […]
