Large Scale Structures in the CANDELS Fields: The Role of the Environment in Star Formation Activity
Nima Chartab, Bahram Mobasher, Behnam Darvish +14
We present a robust method, weighted von Mises kernel density estimation, along with boundary correction to reconstruct the underlying number density field of galaxies. We apply th…
Graphether: A Two-Dimensional Oxocarbon as a Direct Wide-Gap Semiconductor with High Mechanical and Electrical Performances
Gui-Lin Zhu, Xiao-Juan Ye, Chun-Sheng Liu
Although many graphene derivatives have sizable band gaps, their electrical or mechanical properties are significantly degraded due to the low degree of π-conjugation. Besides the…
The HASHTAG project I. A Survey of CO(3-2) Emission from the Star Forming Disc of M31
Zongnan Li, Zhiyuan Li, Matthew W. L. Smith +26
We present a CO(3-2) survey of selected regions in the M31 disc as part of the JCMT large programme, HARP and SCUBA-2 High-Resolution Terahertz Andromeda Galaxy Survey (HASHTAG). T…
Preliminary demonstration of flexible dual-energy X-ray phase-contrast imaging
Shenghao Wang, Guibin Zan, Qiuping Wang +1
Currently, dual-energy X-ray phase contrast imaging is usually conducted with an X-ray Talbot-Lau interferometer. However, in this system, the two adopted energy spectra have to be…
ACNet: Attention Based Network to Exploit Complementary Features for RGBD Semantic Segmentation
Xinxin Hu, Kailun Yang, Lei Fei +1
Compared to RGB semantic segmentation, RGBD semantic segmentation can achieve better performance by taking depth information into consideration. However, it is still problematic fo…
Detection of Planetary and Stellar Companions to Neighboring Stars via a Combination of Radial Velocity and Direct Imaging Techniques
Stephen R. Kane, Paul A. Dalba, Zhexing Li +13
The sensitivity of radial velocity (RV) surveys for exoplanet detection are extending to increasingly long orbital periods, where companions with periods of several years are now b…
