14. Performance evaluation of 3D computer vision techniques
This work presents the implementation and comparison of three different techniques of three-dimensional computer vision as follows: • Stereo vision - correlation between two 2D images • Sensorial fusion - use of different sensors: camera 2D + ultrasound sensor (1D); • Structured light The computer vision techniques herein presented took into considerat

15. Combinação de métodos de inteligência artificial para fusão de sensores / Combination of artificial intelligence methods for sensor fusion
Robôs móveis dependem de dados provenientes de sensores para ter uma representação do seu ambiente. Porém, os sensores geralmente fornecem informações incompletas, inconsistentes ou imprecisas. Técnicas de fusão de sensores têm sido empregadas com sucesso para aumentar a precisão de medidas obtidas com sensores. Este trabalho propõe e investiga o

16. Split ubiquitin as a sensor of protein interactions in vivo.
We describe an assay for in vivo protein interactions. Protein fusions containing ubiquitin, a 76-residue, single-domain protein, are rapidly cleaved in vivo by ubiquitin-specific proteases, which recognize the folded conformation of ubiquitin. When a C-terminal fragment of ubiquitin (C(ub)) is expressed as a fusion to a reporter protein, the fusion is cleav

17. Correction of the DNA Sequence of the regB Gene of Rhodobacter capsulatus with Implications for the Membrane Topology of the Sensor Kinase RegB
We corrected the previously published sequence for the regB gene, which encodes a histidine sensor kinase in Rhodobacter capsulatus. The deduced RegB amino acid sequence has an additional putative transmembrane domain at the N terminus. Analysis of RegB-PhoA and RegB-LacZ fusion proteins supports a topology model for RegB with six membrane-spanning domains.

18. Absence of synaptotagmin disrupts excitation-secretion coupling during synaptic transmission.
Synaptotagmin is an integral synaptic vesicle protein proposed to be involved in Ca(2+)-dependent exocytosis during synaptic transmission. Null mutations in synaptotagmin have been made in Drosophila, and the protein's in vivo function has been assayed at the neuromuscular synapse. In the absence of synaptotagmin, synaptic transmission is dramatically impair

19. Membrane fusion protein synexin (annexin VII) as a Ca2+/GTP sensor in exocytotic secretion.
Exocytotic membrane fusion and secretion are promoted by the concerted action of GTP and Ca2+, although the precise site(s) of action in the process are not presently known. However, the calcium-dependent membrane fusion reaction driven by synexin (annexin VII) is an in vitro model for this process, which we have now found to be further activated by GTP. The

20. SNAP-25 and synaptotagmin involvement in the final Ca(2+)-dependent triggering of neurotransmitter exocytosis.
In neurons, depolarization induces Ca2+ influx leading to fusion of synaptic vesicles docked at the active zone for neurotransmitter release. While a number of proteins have now been identified and postulated to participate in the assembly and subsequent disengagement of a vesicle docking complex for fusion, the mechanism that ultimately triggers neuroexocyt

21. 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

22. Probing the transmembrane topology of cyclic nucleotide-gated ion channels with a gene fusion approach.
Cyclic nucleotide-gated (CNG) cation channels contain two short sequence motifs--a residual voltage-sensor (S4) and a pore-forming (P) segment--that are reminiscent of similar segments in voltage-activated Shaker-type K+ channels. It has been tacitly assumed that CNG channels and this K+ channel subfamily share a common overall topology, characterized by a h

23. Autophosphorylation and phosphotransfer in the Bordetella pertussis BvgAS signal transduction cascade.
Expression of adhesins, toxins, and other virulence factors of Bordetella pertussis is under control of the BvgA and BvgS proteins, members of a bacterial two-component signal transduction family. BvgA bears sequence similarity to regulator components, whereas BvgS shows similarity to both sensor and regulator components. BvgA and the cytoplasmic portion of

24. Intracellular calcium dependence of large dense-core vesicle exocytosis in the absence of synaptotagmin I
Synaptotagmin I is a synaptic vesicle-associated protein essential for synchronous neurotransmission. We investigated its impact on the intracellular Ca2+-dependence of large dense-core vesicle (LDCV) exocytosis by combining Ca2+-uncaging and membrane capacitance measurements in adrenal slices from mouse synaptotagmin I null mutants. Synaptotagmin I-def
