Plasma Tail and Dust Tail of Comets
1994Generally, a comet has two tails; the blue plasma tail and the red dust tail (or Type 1 (ion) tail and Type 2 (dust) tail). The plasma tail is caused by an interaction between the solar wind and the cometary plasma, while the dust tail is by the solar radiation pressure to the cometary dust. The first purpose of the present paper is to review our works

The sign has been originally described on chest radiographs. It is formed by distorted blood vessel(s) and a focal area of atelectatic lung adjacent to pleural thickening. The vessel(s) are seen as curvilinear soft tissue density or densities, extending from the medial margin of the atelectatic lung to the pulmonary hilum. When the vessels are multiple

A description and explanation of an unexpected echographic appearance in a patient who had sustained an abdominal shotgun wound is presented. In the B-scans, a trail of dense continuous echoes, simulating a comet tail, is seen distal to each lead pellet. This comet tail appearance is shown to be a type of reverberation artifact.

Vaccinia virus moves around infected cells propelled by comet-like actin tails. Newsome et al. (see the Perspective by Hall) have uncovered an outside-in signaling mechanism, induced by extracellular vaccinia virus particles, that is ultimately responsible for stimulating actin-based motility of vaccinia virus by ...
