Adolescents and Adults Use Different Facial Movements and Vocal Cues to Express Emotions

Developmental Science, Volume 29, Issue 4, July 2026.
ABSTRACT Current understanding of how facial and vocal cues can communicate emotional intent is based on patterns observed in adults, with surprisingly little known about age‐related differences in nonverbal expression. Do adolescents and adults use different nonverbal cues to express emotions? This cross‐sectional laboratory study revealed age‐related

An investigation of a frequency diverse array

, 2009
This thesis presents a novel concept for focusing an antenna beam pattern as a function of range, time, and angle. In conventional phased arrays, beam steering is achieved by applying a linear phase progression across the aperture.

Fundamental aspects of netted radar performance

, 2010
Netted radar employs several spatially distributed transmitters and receivers for information retrieval. This system topology offers many advantages over traditional monostatic and bistatic systems which use a single transmitter and a single receiver ...

Target models and waveform design for detection in MIMO radar

, 2014
In this paper, we propose a general target model for multiple-input multiple-output (MIMO) radar. Two types of targets are presented. For each type of target, we develop a corresponding optimum waveform designing method to optimize detection performance.
