The effect of past condition on a multicomponent sexual signal [PDF]
Proceedings of the Royal Society of London. Series B: Biological Sciences, 2003 Sexual-selection theory predicts that multiple signals may reveal male condition at different stages of life, thus allowing females to make a more reliable assessment of male quality. While the effect of current condition on signal design is well established, few studies have experimentally investigated the effects of past condition.

Separation of Multicomponent Micro-Doppler Signal with Missing Samples
Remote SensingThe problem of separating multicomponent micro-Doppler (m-D) signals is common in the field of radar signal processing. In some implementations, it is necessary to separate the multicomponent m-D signal that contains missing samples.

Model Order Selection in Multi-baseline Interferometric Radar Systems
EURASIP Journal on Advances in Signal Processing, 2005 Synthetic aperture radar interferometry (InSAR) is a powerful technique to derive three-dimensional terrain images. Interest is growing in exploiting the advanced multi-baseline mode of InSAR to solve layover effects from complex orography, which ...

Artificial molecular machines and motors—Design and control of nanoscale motion
FEBS Letters, EarlyView.Molecules are constantly moving because of thermal fluctuations, but random motion alone cannot be exploited to perform directional tasks. Artificial molecular machines use chemical, electrical, or light energy to bias this motion. Molecular shuttles, rotary motors, and supramolecular pumps illustrate how nanoscale movement can be controlled and ...

EURASIP Journal on Advances in Signal Processing, 2009 A class of time-frequency distributions with complex-lag argument is proposed. It is based on the ambiguity domain representations of real and complex-lag moment, combined to provide a cross-terms free representation for multicomponent signals ...

Method of Elements Identification in the Multicomponent Signal
Control Systems and Computers, 2023 To measure concentrations of toxic elements in analytical systems of ecological monitoring, a generative model of a multicomponent differential signal of stripping chronopotentiometry is used in the coordinates of potentials in time (е, dt/dе) in the form of a model of the capacitive background discharge of electrodes (base curve) and the sum of the ...
