Human breathing perception system based on Wi-Fi subcarrier mutual information

Tongxin xuebao
The unpredictable environmental changes cause large fluctuations in Wi-Fi signals, and it is difficult to quantify the static and behaviorally-aware dynamic components in the subcarriers, so it is not possible to accurately portray the fluctuating form ...

Herschelimages of NGC 6720: H2formation on dust grains [PDF]

Astronomy and Astrophysics, 2010
Herschel PACS and SPIRE images have been obtained of NGC 6720 (the Ring nebula). This is an evolved planetary nebula with a central star that is currently on the cooling track, due to which the outer parts of the nebula are recombining. From the PACS and

JWST observations of the Ring Nebula (NGC 6720) – II. PAH emission [PDF]

Monthly Notices of the Royal Astronomical Society
Polycyclic aromatic hydrocarbons (PAHs) and carbonaceous dust have been observed in clumpy circumstellar environments, yet their formation and evolutionary pathways in such environments remain elusive.

JWST observations of the Ring Nebula (NGC 6720): I. Imaging of the rings, globules, and arcs [PDF]

Monthly Notices of the Royal Astronomical Society
We present JWST images of the well-known planetary nebula NGC 6720 (the Ring Nebula), covering wavelengths from 1.6 to 25  m. The bright shell is strongly fragmented with some 20 000 dense globules, bright in H2, with a characteristic diameter of 0.2 ...
