Journal of Geophysical Research: Machine Learning and Computation, Volume 3, Issue 5, October 2026.Abstract We propose a variational autoencoder framework to directly assess uncertainties in subsurface models produced by single‐ and multiparameter full waveform inversion (FWI). The new method does not require pretraining on labeled data, thus it significantly reduces computational cost and storage requirements.

Pulse Response Measurement and Processing by Six-Port Reflectometr
Advances in Electrical and Electronic Engineering, 2008 In this paper the pulse response estimation of radio channel by Six-port reflectometer (SPR) is described. The measurement of pulse response is in real time, with baseband conversion and without demodulation.

Journal of Geophysical Research: Machine Learning and Computation, Volume 3, Issue 5, October 2026.Abstract Full‐waveform inversion (FWI) relies on sequential‐source (SQ) workflows for high imaging precision, while simultaneous‐source (SML) encoding drastically accelerates computation but introduces irreversible wavenumber discontinuity artifacts in hybrid‐domain implementations.

Concurrency and Computation: Practice and Experience, Volume 38, Issue 15, August 2026.ABSTRACT This paper presents MusicoCrypt, a context‐bound music‐modulated stream‐encryption framework that incorporates audio‐derived public side information into a pseudorandom‐function‐centered encryption workflow. A shared reference recording is processed using a pitch‐tracking pipeline, and ordered note pairs are encoded as residues in ℤ132 ...

Concurrency and Computation: Practice and Experience, Volume 38, Issue 16, August 2026.ABSTRACT Photonic matrix processors are attracting attention in applications such as AI inference due to their low‐power and low‐latency properties. However, their applicability has been largely limited to low‐precision computation due to inherent stochastic analog noise and device non‐idealities.

HELIOS ‐ Highly rEliable Links durIng sOlar conjunctionS
Radio Science, Volume 61, Issue 8, August 2026.Abstract During deep space missions, maintaining reliable communication between a spacecraft and Earth becomes particularly challenging during superior solar conjunctions, when the spacecraft passes behind the Sun relative to Earth. The highly ionized solar corona and solar wind create plasma inhomogeneities that severely affect radio signals, leading ...

Radio Science, Volume 61, Issue 8, August 2026.Abstract This paper explores the impact of natural phenomena on signal data transmission across various ionospheric communication channels. The study focuses on three primary phenomena: meteor trails prevalent in the middle‐ and lower‐latitude ionosphere, bubble and plume structures observed around the equatorial ionosphere, and magnetic‐storm‐induced ...
