JWST/NIRSpec Detects Warm CO Emission in the Terrestrial-planet Zone of HD 131488

The Astrophysical Journal
We have obtained a high-resolution, JWST NIRSpec 2.87–5.14 μ m spectrum of the debris disk around HD 131488. We discover CO fundamental emission indicating the presence of warm fluorescent gas within ∼10 au of the star.

Space Debris Detection and Tracking Using Star Trackers

, 2019
The near Earth space environment is becoming crowded with space debris and must be regarded a critical resource for future spacecraft missions. To ensure continuous access to this resource, future Low Earth orbit users have responsibility, both for savvy usage, as well as to contribute knowledge of the environment.

Foodborne diseases event detection based on short text

大数据, 2016
MicroBlog is a typical short text data source for event detection. Because of diversity, sparsity and debris in MicroBlog content, using existing event detection method is ineffective, and the event spatio-temporal information is inaccurate.
