A Recipe for Unbiased Background Modeling in Deep Wide-Field Astronomical Images
Qing Liu, Roberto G. Abraham, Peter G. Martin +9
Unbiased sky background modeling is crucial for the analysis of deep wide-field images, but it remains a major challenge in low surface brightness astronomy. Traditional image proc…
Template-based eukaryotic genome editing directed by SviCas3
Wang-Yu Tong, Yong Li, Shou-Dong Ye +7
RNA-guided gene editing based on the CRISPR-Cas system is currently the most effective genome editing technique. Here, we report that the SviCas3 from the subtype I-B-Svi Cas syste…
Distributed Aperture Telescopes and the Dragonfly Telephoto Array
Roberto G. Abraham, Pieter G. van Dokkum, Deborah M. Lokhorst +4
Telescope arrays allow high-performance wide-field imaging systems to be built more quickly and at lower cost than conventional telescopes. Distributed aperture telescopes (the pre…
Quasiconvexity preserving property for fully nonlinear nonlocal parabolic equations
Takashi Kagaya, Qing Liu, Hiroyoshi Mitake
This paper is concerned with a general class of fully nonlinear parabolic equations with monotone nonlocal terms. We investigate the quasiconvexity preserving property of positive,…
Stellar halos from The Dragonfly Edge-on Galaxies Survey
Colleen Gilhuly, Allison Merritt, Roberto Abraham +6
We present the primary results from the Dragonfly Edge-on Galaxies Survey (DEGS), an exploration of the stellar halos of twelve nearby ( Mpc) edge-on disc galaxies with the…
Asymptotic stability of diffusion waves of a quasi-linear hyperbolic-parabolic model for vasculogenesis
Qinging Liu, Hongyun Peng, Zhi-An Wang
In this paper, we derive the large-time profile of solutions to the Cauchy problem of a hyperbolic-parabolic system modeling the vasculogenesis in . When the initial data are…
Quantum dynamics on a lossy non-Hermitian lattice
Li Wang, Qing Liu, Yunbo Zhang
We investigate quantum dynamics of a quantum walker on a finite bipartite non-Hermitian lattice, in which the particle can leak out with certain rate whenever it visits one of the…
The Dragonfly Wide Field Survey. II. Accurate Total Luminosities and Colors of Nearby Massive Galaxies and Implications for the Galaxy Stellar Mass Function
Tim B. Miller, Pieter van Dokkum, Shany Danieli +8
Stellar mass estimates of massive galaxies are susceptible to systematic errors in their photometry, due to their extended light profiles. In this study we use data from the Dragon…
Singular Neumann boundary problems for a class of fully nonlinear parabolic equations in one dimension
Takashi Kagaya, Qing Liu
In this paper, we discuss singular Neumann boundary problem for a class of nonlinear parabolic equations in one space dimension. Our boundary problem describes motion of a planar c…
A Deep Gradient Boosting Network for Optic Disc and Cup Segmentation
Qing Liu, Beiji Zou, Yang Zhao +1
Segmentation of optic disc (OD) and optic cup (OC) is critical in automated fundus image analysis system. Existing state-of-the-arts focus on designing deep neural networks with on…
DDNet: Cartesian-polar Dual-domain Network for the Joint Optic Disc and Cup Segmentation
Qing Liu, Xiaopeng Hong, Wei Ke +2
Existing joint optic disc and cup segmentation approaches are developed either in Cartesian or polar coordinate system. However, due to the subtle optic cup, the contextual informa…
The THU-NAOC Transient Survey: the Performance and the First-year Result
Tianmeng Zhang, Xiaofeng Wang, Junchen Chen +18
The Tsinghua University-National Astronomical Observatories of China (NAOC) Transient Survey (TNTS) is an automatic survey for a systematic exploration of optical transients (OTs),…
