A Sum-of-Squares and Semidefinite Programming Approach for Maximum Likelihood DOA Estimation

open access: yesSensors, 2016
Direction of arrival (DOA) estimation using a uniform linear array (ULA) is a classical problem in array signal processing. In this paper, we focus on DOA estimation based on the maximum likelihood (ML) criterion, transform the estimation problem into a ...

Evaluation of Genetics in the Association Between Cardiorespiratory Fitness and Health

open access: yesScandinavian Journal of Medicine &Science in Sports, Volume 36, Issue 5, May 2026.
ABSTRACT We evaluated how much cardiorespiratory fitness (CRF)‐related genetics contribute to the risk of common noncommunicable diseases (NCDs) and mortality, and whether individuals with different levels of CRF and genetic predispositions differ in health characteristics.

Direction-of-Arrival Estimation of Virtual Array Signals Based on Doppler Effect

open access: yesInternational Journal of Distributed Sensor Networks, 2015
The estimation accuracy of direction-of-departure (DOD) and direction-of-arrival (DOA) is reduced because of Doppler shifts caused by the high-speed moving sources.

Satellite‐Based Detection of Methane Emissions From Permafrost Peatland Warming

open access: yesGeophysical Research Letters, Volume 53, Issue 7, 16 April 2026.
Abstract Column‐averaged methane (XCH4) observations spanning 2018–2023 by the Tropospheric Monitoring Instrument (TROPOMI) on the Sentinel‐5 Precursor satellite are assessed for evidence of methane (CH4) emissions from permafrost regions. Bi‐monthly TROPOMI XCH4 anomaly maps and soil temperature (Tsoil) anomaly maps from reanalysis data are generated ...

Polynomial Manifold Interpolation for Direction Finding in the Presence of Mutual Coupling

open access: yesIEEE Access, 2019
Direction-of-arrival (DOA) estimation in the presence of mutual coupling among the antennas is an important problem in direction finding systems. To address the mutual coupling issue, a polynomial manifold interpolation approach is proposed in this paper.
