Precise prediction on brain age is urgently needed by many biomedical areas including mental
rehabilitation prognosis as well as various medicine or treatment trials. People began to …

A micro-Doppler active acoustic sensing system is described. We report its use in acquiring
gait signatures of humans and four-legged animals in indoor and outdoor environments. …

The characteristics of a rubidium clock and the relationship between the clock offset error
and position error were investigated. An adaptive filter algorithm and a rubidium clock aided …

A portable acoustic micro-Doppler radar system for the acquisition of human gait signatures
in indoor and outdoor environments is reported. Signals from an accelerometer attached to …

Democratic AI, aiming at developing AI systems aligned with human values, holds promise
for making AI services accessible to people. However, concerns have been raised regarding …

Eliminating poverty is the primary goal of sustainable development. China has eliminated
absolute poverty in 2020, yet there is a chance that it could happen again. The poor population …

State space harmonic distortion modeling and estimation are introduced for G/sub m/-C
filters with fully balanced, weakly nonlinear tranconductors. The proposed method provides …

Salinity is a major abiotic stress that harms rice growth and productivity. Low phosphate roots
(LPRs) play a central role in Pi deficiency-mediated inhibition of primary root growth and …

Active acoustic scene analysis is a promising approach to distributed persistent surveillance
in sensor networks. We report on the design of bandpass sampling technique for an …

Foams have been considered effective diverters to decrease the mobility in the steam channel
for heavy oil-recovery processes. Due to the high weight of chemical additive loss caused …
