13. Electronic system for data aquisition, processing and biological signal storage according to standard IEEE 1451.4. / Sistema eletrônico para aquisição, processamento e armazenamento de sinais biológicos baseado na norma IEEE 1451.4.
The purpose of this work was the development of an acquisition, processing and storage system of a signal from an arrangement of sensors based on IEEE 1451.4 standard, resulting in a plug&play sensors system. The acquisition signal system proposed will permit to monitoring several kinds of sensors for a variety application in the fields of biomedical, indust

14. Construção de uma bancada de ensaio e avaliação de um sistema de mensuração da produtividade de grãos. / Construction of a laboratory bench and evaluation of a grain yield monitor.
With the progress of the precision agriculture where spatial yield variability is taken into account, it is necessary to improve data collection so the results can be more reliable. It is necessary to understand how yield sensor used on combines works in order to know the accuracy of the field data for generation of the yield maps. This work aims to characte

15. Sensor-independent stimulus representations
This paper shows how time-dependent sensory data from an evolving stimulus can be blindly rescaled in a nonlinear time-dependent fashion to create a time series of stimulus representations that are invariant under any unknown invertible transformation of the sensory data. These representations are invariant, because they encode “inner” properties of the

16. Probing Conservation of HAMP Linker Structure and Signal Transduction Mechanism through Analysis of Hybrid Sensor Kinases
The HAMP linker, a predicted structural element observed in many sensor kinases and methyl-accepting chemotaxis proteins, transmits signals between sensory input modules and output modules. HAMP linkers are located immediately inside the cytoplasmic membrane and are predicted to form two short amphipathic α-helices (AS-1 and AS-2) joined by an unstructured

17. Locating protein-coding regions in human DNA sequences by a multiple sensor-neural network approach.
Genes in higher eukaryotes may span tens or hundreds of kilobases with the protein-coding regions accounting for only a few percent of the total sequence. Identifying genes within large regions of uncharacterized DNA is a difficult undertaking and is currently the focus of many research efforts. We describe a reliable computational approach for locating prot

18. Engineering of Ion Sensing by the Cystathionine β-Synthase Module of the ABC Transporter OpuA*
We have previously shown that the C-terminal cystathionine β-synthase (CBS) domains of the nucleotide-binding domains of the ABC transporter OpuA, in conjunction with an anionic membrane surface function, act as sensor of internal ionic strength (Iin). Here, we show that a surface-exposed cationic region in the CBS module domain is critical for ion sen

19. Identification of nucleocytoplasmic cycling as a remote sensor in cellular signaling by databased modeling
Considerable progress has been made in identifying the molecular composition of complex signaling networks controlling cell proliferation, differentiation, and survival. However, to discover general building principles and predict the dynamic behavior of signaling networks, it is necessary to develop quantitative models based on experimental observations. He

20. The NAF domain defines a novel protein–protein interaction module conserved in Ca2+-regulated kinases
The Arabidopsis calcineurin B-like calcium sensor proteins (AtCBLs) interact with a group of serine-threonine protein kinases (AtCIPKs) in a calcium-dependent manner. Here we identify a 24 amino acid domain (NAF domain) unique to these kinases as being required and sufficient for interaction with all known AtCBLs. Mutation of conserved residues either abolis

21. Functional dissection of the transmitter module of the histidine kinase NtrB in Escherichia coli
Signal transduction by two-component systems involves phosphorylation and thereby activation of the response regulator by the cognate histidine kinase. Bifunctional histidine kinases have two opposing activities: depending on the environmental stimuli they either promote phosphorylation or stimulate the rapid dephosphorylation of the response regulator. To d

22. FKBP12-rapamycin-associated protein associates with mitochondria and senses osmotic stress via mitochondrial dysfunction
FKBP12-rapamycin associated protein (FRAP, also known as mTOR or RAFT) is the founding member of the phosphatidylinositol kinase-related kinase family and functions as a sensor of physiological signals that regulate cell growth. Signals integrated by FRAP include nutrients, cAMP levels, and osmotic stress, and cellular processes affected by FRAP include tran

23. Integration of multiple domains in a two-component sensor protein: the Bordetella pertussis BvgAS phosphorelay.
BvgS and BvgA, a two-component system, regulate virulence gene expression in Bordetella pertussis. BvgS is a transmembrane sensor protein that can autophosphorylate and phosphorylate BvgA. Phosphorylated BvgA activates transcription of virulence genes. The cytoplasmic region of BvgS contains three domains separated by alanine/proline-rich sequences--the tran

24. Altered Phosphotransfer in an Activated Mutant of the Saccharomyces cerevisiae Two-Component Osmosensor Sln1p
The SLN1 two-component signaling pathway of Saccharomyces cerevisiae utilizes a multistep phosphorelay mechanism to control osmotic stress responses via the HOG1 mitogen-activated protein kinase pathway and the transcription factor Skn7p. Sln1p consists of a sensor kinase module that undergoes histidine autophosphorylation and a receiver module that autocata
