Intelligent Acousto‐Electrical Metamaterials (IAM) for Sound Source Detection

Advanced Materials, Volume 38, Issue 36, 26 June 2026.
Our proposed metamaterial concept enables sound source detection using a single material, in contrast to conventional arrays that require dozens or even hundreds of transducers. We show that the coupled acoustic–vibrational–electrical responses in piezoelectric metamaterials give rise to topology‐governed charge transport, producing distinct voltage ...

Small Aperture Antenna Arrays for Direction of Arrival Estimation

Sensors
In this paper, we establish criteria for the design of small aperture antenna arrays for Direction of Arrival (DOA) estimation. We define a small aperture antenna array as one consisting of a few elements with an average interelement spacing less than or

Microstructural Evidence for Early Childhood Stress in a Community in Transition at Hisban, Jordan

American Journal of Biological Anthropology, Volume 190, Issue 2, June 2026.
ABSTRACT Objectives Identification of stress across infancy and childhood can reflect maternal and environmental influences on early life health. In the 19th century community of Hisban, many infants died before 2 years of age with evidence of metabolic disease, including rickets, that likely ties with maternal health.

Wideband DOA Estimation on Co-prime Array via Atomic Norm Minimization

Energies, 2020
This paper introduces a low complexity wideband direction-of-arrival (DOA) estimation algorithm on the co-prime array. To increase the number of the detectable signal sources and to prevent an unnecessary increase in complexity, the low dimensional co ...

DOA estimation for periodically modulated sources [PDF]

EURASIP Journal on Advances in Signal Processing, 2013
This paper considers the problem of direction-of-arrival estimation for periodically modulated signals using one uniform linear array of sensors. By means of modulating the sources with periodic modulation sequences, we can form a series of linear equations relating the autocorrelation matrices of the received data and the outer products of the scaled ...

Sparse DOA estimation with polynomial rooting [PDF]

, 2015
Direction-of-arrival (DOA) estimation involves the localization of a few sources from a limited number of observations on an array of sensors. Thus, DOA estimation can be formulated as a sparse signal reconstruction problem and solved efficiently with ...
