Effect of nonidentical signal phases on signal amplification of two coupled excitable neurons
(ElsevierAmsterdam, 2014-03-15)
In this paper, we study the response of two coupled excitable neurons to external subthreshold periodic signals. We find that the neurons' response to the subthreshold signals can be enhanced when the signal phases are ...
Signals in Communication Engineering History
(IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC, 2010)
This paper is a study of various electric signals, which have been employed throughout the history of communication engineering in its two main landmarks: the telegraph and the telephone. The signals are presented in their ...
A tutorial on signal energy and its applications
(2016-02-29)
This tutorial, dedicated both to young professionals and students working with digital signal processing and pattern recognition, introduces three feature extraction approaches based on signal energy, characterising ...

Retroactive Signaling in Short Signaling Pathways
(Public Library of Science, 2012-07)
In biochemical signaling pathways without explicit feedback connections, the core signal transduction is usually described as a one-way communication, going from upstream to downstream in a feedforward chain or network of ...
Multimodal signaling in Boana albopunctata (Anura: Hylidae): reading visual and acoustic cues
(Univ Sao Paulo, Esalq, 2020-12-01)
The acoustic mode of communication is important for anurans, but visual communication is beginning to be considered essential for some species, genera, and families. This study focuses on visual and acoustic signals in ...
Autoregressive decomposition and pole tracking applied to vocal fold nodule signals
(2007-08-01)
This letter describes a novel algorithm that is based on autoregressive decomposition and pole tracking used to recognize two patterns of speech data: normal voice and disphonic voice caused by nodules. The presented method ...
Wnt-regulated dynamics of positional information in zebrafish somitogenesis
(Company Of Biologists, 2014-03)
How signaling gradients supply positional information in a field of moving cells is an unsolved question in patterning and morphogenesis. Here, we ask how a Wnt signaling gradient regulates the dynamics of a wavefront of ...

Pedestrian signalization and the risk of pedestrian-motor vehicle collisions in Lima, Peru
(Elsevier, 2014)
Safe walking environments are essential for protecting pedestrians and promoting physical activity. In Peru, pedestrians comprise over three-quarters of road fatality victims. Pedestrian signalization plays an important ...
