Outflowing Gas in the Planetary Nebula K 3-54
Xiuhui Chen, Dejian Liu, Ping Yan +3
As planetary nebulae (PNe) evolve, they develop slow and strong dust-driven stellar winds, making the joint study of dust and gas essential for understanding their nature. As a pil…
Optical skyrmions from metafibers
Tiantian He, Yuan Meng, Lele Wang +7
Optical skyrmions are an emerging class of structured light with sophisticated particle-like topologies with great potential for revolutionizing modern informatics. However, the cu…
PMO Polaris CO survey. I. A 100 deg view of the Polaris Flare
Xunchuan Liu, Bing-Gang Ju, Fujun Du +10
Large-area CO surveys are essential for studying molecular cloud dynamics and evolution; however, most have focused on the Galactic plane, leaving high-latitude clouds less explore…
The Milky Way Imaging Scroll Painting Survey: Data Release 1
Ji Yang, Qing-Zeng Yan, Yang Su +31
We present the first data release (DR1) of the Milky Way Imaging Scroll Painting (MWISP) survey, a mapping in the J=(1-0) transition lines of 12CO, 13CO, and C18O toward the northe…
Permanence and universal classification of discrete-time competitive systems via the carrying simplex
Mats Gyllenberg, Jifa Jiang, Lei Niu +1
We study the permanence and impermanence for discrete-time Kolmogorov systems admitting a carrying simplex. Sufficient conditions to guarantee permanence and impermanence are provi…
PMO Polaris CO survey. II. Where is the dust?
Xunchuan Liu, Bing Gang Ju, Fujun Du +10
Dust plays critical chemical and dynamical roles in the interstellar medium (ISM), but its specific association with molecular and atomic gas remains difficult to isolate. Combinin…
Anomaly Detection in Streaming Sensor Data
Alec Pawling, Ping Yan, Julián Candia +2
In this chapter we consider a cell phone network as a set of automatically deployed sensors that records movement and interaction patterns of the population. We discuss methods for…
On a Conjecture by Ren and Li
Yongbing Luo, Ping Yan
This paper proves a conjecture proposed by Ren and Li (2015: 393, \emph{Journal of Inequalities and Applications}). Our result eliminates the constraints on the parity and size of…
On the initiation of fiber fuse damage in high-power ytterbium-doped fiber lasers
Jiading Tian, Zehui Wang, Qirong Xiao +3
Fiber fuse effect can occur spontaneously and propagate along optical fibers to cause wide-spread damage; it threatens all applications involving optical fibers. This paper present…
