Annexin-Mediated Calcium Signalling in Plants

open access: yesPlants, 2014
Calcium-permeable channels underpin elevations of free calcium that encode specific signals in stress adaptation, development and immunity. Identifying the genes encoding these channels remains a central goal of plant signalling research.

The ComX Quorum Sensing Peptide of Bacillus subtilis Affects Biofilm Formation Negatively and Sporulation Positively

open access: yesMicroorganisms, 2020
Quorum sensing (QS) is often required for the formation of bacterial biofilms and is a popular target of biofilm control strategies. Previous studies implicate the ComQXPA quorum sensing system of Bacillus subtilis as a promoter of biofilm formation ...

DIFFERENT METHODS FOR REMOTE SENSING DATA INTEGRATION [PDF]

open access: yesGeodetski Glasnik, 2018
Nowadays remote sensing is an indispensable source of information about Earth's surface, primarily satellite-based remote sensing systems. Traditionally, the analysis of data collected from a particular area was based on the analysis of the data of one ...

Signal transduction and signaling networks

open access: yesMolecular Biology of the Cell, 2013
Cellular signaling can be complex and dynamic. In the past several decades, it has become clear that many signal transduction pathways are not simple one-way transmissions of upstream stimuli, but are mediated through extremely complicated networks. Our next challenge is to move beyond the static biochemical description of networks into developing a ...

The library of reference models of the physical layer signals

open access: yesНаука. Инновации. Технологии, 2022
The wireless communication is very widely used information transmission systems. Wireless networks differ from cable networks on physical and partially on data link layer OSI in use of different methods of modulation.

A Digital Signal Amplification Device for Microelectrode Arrays based on Stochastic Resonance

open access: yesAdvances in Electrical and Computer Engineering, 2020
In this work, an experimental study was carried out about the construction of an amplification equipment based on the phenomenon of stochastic resonance (SR), which was initially thought to detect spikes and bursts from human and animal neuronal tissue,

Sensory Systems and Transcriptional Regulation in Escherichia coli

open access: yesFrontiers in Bioengineering and Biotechnology, 2022
In free-living bacteria, the ability to regulate gene expression is at the core of adapting and interacting with the environment. For these systems to have a logic, a signal must trigger a genetic change that helps the cell to deal with what implies its ...

Signal codes [PDF]

open access: yesProceedings 2003 IEEE Information Theory Workshop (Cat. No.03EX674), 2004
Motivated by signal processing, we present a new class of channel codes, called signal codes, for continuous-alphabet channels. Signal codes are lattice codes whose encoding is done by convolving an integer information sequence with a fixed filter pattern.

For Heart Rate Assessments from Drone Footage in Disaster Scenarios

open access: yesBioengineering, 2023
The ability to use drones to obtain important vital signs could be very valuable for emergency personnel during mass-casualty incidents. The rapid and robust remote assessment of heart rates could serve as a life-saving decision aid for first-responders.
