25. Álgebra de mapas e sua aplicações em sensoriamento remoto e geoprocessamento / Map algebra and its application in remote sensing and geoprocessing
The term "Map Algebra" is used in the Geoprocessing and Remote Sensing literature to denote the set of operators that handle geographic fields (images, thematic maps and numerical terrain models). This work analyzes the different questions involved in the conception, implementation and use of the operators from Map Agebra. In the conceptual analysis, this wo

26. EQUIVALENTE DINÂMICO POR AGREGAÇÃO DE GERADORES COERENTES / COHERENCY - BASED DYNAMIC EQUIVALENT
The spread and the interconection of Electrical Power Systems have been stressed the employment of dynamic equivalents by Electrical Power Companies for representing system áreas that they are not responsible for at planning and operation studies. Due to system model dimension reduction, studies have become faster with reduced costs and computational task r

27. Reentrant signaling among simulated neuronal groups leads to coherency in their oscillatory activity.
Recent experiments have revealed tightly synchronized oscillatory discharges in local assemblies of cortical neurons as well as phase coherency of oscillations at distant cortical sites. These findings are consistent with the theory of neuronal group selection, a population theory of brain function that is based on the properties of local groups of neurons.

28. When the brain changes its mind: Interocular grouping during binocular rivalry
The prevalent view of binocular rivalry holds that it is a competition between the two eyes mediated by reciprocal inhibition among monocular neurons. This view is largely due to the nature of conventional rivalry-inducing stimuli, which are pairs of dissimilar images with coherent patterns within each eye’s image. Is it the eye of origin or the coher

29. Solid-like character of virus solutions.
The solid-like behavior of turnip yellow mosaic virus solutions following the extrusion of viral RNA in alkali was observed with a torsion-fiber balance developed for the purpose. This method provided a direct measurement of the yield stresses required to break or liquefy these solutions. The yield stresses were found to increase and to be less time dependen

30. Intracortical and corticothalamic coherency of fast spontaneous oscillations.
We report that fast (mainly 30- to 40-Hz) coherent electric field oscillations appear spontaneously during brain activation, as expressed by electroencephalogram (EEG) rhythms, and they outlast the stimulation of mesopontine cholinergic nuclei in acutely prepared cats. The fast oscillations also appear during the sleep-like EEG patterns of ketamine/xylazine

31. Data transferability from model organisms to human beings: Insights from the functional genomics of the flightless region of Drosophila
At what biological levels are data from single-celled organisms akin to a Rosetta stone for multicellular ones? To examine this question, we characterized a saturation-mutagenized 67-kb region of the Drosophila genome by gene deletions, transgenic rescues, phenotypic dissections, genomic and cDNA sequencing, bio-informatic analysis, reverse transcription–P
