A high-sensitivity pressure sensor was deployed as part of the Mars Interior Exploration using Seismic Investigations, Geodesy and Heat Transport lander on Elysium Planitia in November 2018. We use records from 1 October to 31 December 2019 (Sol 301–389) for frequencies between 0.1 0.5 Hz infer relative sound-speed changes Martian atmosphere autocorrelation infrasound interferometry method. fin...

The semiclassical expression for the momentum autocorrelation function of a particle in a one-dimensional box is analyzed. The classical autocorrelation function is shown to be the first term of the semiclassical series. Systematical inclusion of all the terms restores quantum recurrence of the momentum autocorrelation function. 2005 Elsevier B.V. All rights reserved.

The autocorrelation of a key stream sequence in a stream cipher is an important cryptographic property. This paper proposes two constructions of binary interleaved sequences of period 4N by selecting appropriate shift sequences, subsequences and complement sequences. And the autocorrelation functions of new sequences are given. The results show that these sequences have low autocorrelation unde...
