TL;DR: In this paper, the results of extensive field trial campaigns conducted in several countries, totaling over 1100 km, were presented, focusing on challenging low-latency, high-reliability vehicle-to-vehicle (V2V) safety applications including intersection collision warn- ing, turn across path, emergency electronic brake light, do not pass warning, and precrash sensing.

TL;DR: For more than 20 years, an "Interstellar Precursor Mission" has been discussed as a high-priority mission for multiple scientific objectives as discussed by the authors, but the main difficulty with actually carrying out such a mission is the need for reaching significant penetration into the interstellar medium (∼1000 Astronomical Units (AU)) within the working lifetime of the initiators.

Star tracker scan mode capability for the New Horizons mission
TL;DR: The A-STR star tracker for the New Horizons mission to Pluto and the Kuiper Belt is designed to operate autonomously both in a standard "staring" mode and in a star scanning mode as discussed by the authors.

Multipath Parameter Estimation from OFDM Signals in Mobile Channels
TL;DR: It is shown that the frequency domain channel coefficients for an entire packet can be expressed as the superimposition of two-dimensional complex sinusoids in Gaussian noise and proposed a low complexity suboptimal solution based on iterative successive and parallel cancellation.
