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 ...
Compressive Sensing for Inverse Scattering
(2008-06-30)
Compressive sensing is a new field in signal processing and applied mathematics. It allows one to simultaneously sample and compress signals which are known to have a sparse representation in a known basis or dictionary ...
Beamforming echo-localization system using multitone excitation signals
(Institute of Electrical and Electronics Engineers Inc., 2017)
Determining the position of a target is the central issue in several engineering problems, from computer vision to sonar or radar systems. Echo-localization systems use the reflected sound waves to extract information from ...
Digital Signal Processing
(2017-01-31)
A DSP is a specialized processor that does signal processing very efficiently. (consume less time, energy and power than a general-purpose microprocessor when carrying out signal processing tasks).
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 ...
Localized nuclear and perinuclear Ca2+ signals in intact mouse skeletal muscle fibers
(Frontiers Media, 2015)
Nuclear Ca2+ is important for the regulation of several nuclear processes such as gene expression. Localized Ca2+ signals (LCSs) in skeletal muscle fibers of mice have been mainly studied as Ca2+ release events from the ...
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 ...
