Local and global Ca2+ signals: physiology and pathophysiology
(Sociedad de Biología de Chile, 2004)
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 ...
Pilot tone aided measurements to extend the bandwidth of radio frequency applications
(Elsevier B.V., 2016)
A technique to extend the effective measurement bandwidth of a non-coherent vector receiver is presented. This bandwidth extension technique relies on the use of a pilot signal (known a priori), which is added on the signal ...
Calcium signal compartmentalization

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 ...
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 ...
Endoplasmic reticulum calcium signaling in nerve cells

Mitochondria fine-tune the slow Ca2+ transients induced by electrical stimulation of skeletal myotubes
(Elsevier Ltd, 2010)
Mitochondria sense cytoplasmic Ca2+ signals in many cell types. In mammalian skeletal myotubes, depolarizing stimuli induce two independent cytoplasmic Ca2+ signals: a fast signal associated with contraction and a slow ...
