1. Signatures factory: a dynamic alternative for teaching - learning layout concepts and waste disposal
Abstract The use of games and simulation has now spread as a teaching support tool of engineering. This article aims to discuss this reality and this need, presenting as proposed a didactic game in a signature’s factory. From this, it was suggested that the participants involved modify the simulated factory environment through the knowledge acquired during

2. Assinaturas dinâmicas de um sistema coerente com aplicações / Dynamic signatures of a coherent system with applications.
O objetivo da dissertação é analisar a assinatura em um contexto geral que considera a dinâmica no tempo e a dependência estocástica, utilizando a teoria de martingais para processos pontuais.

3. Sistema biométrico híbrido para verificação de assinaturas manuscritas / Hybrid biometric handwritten signature verification system
Through this document the development of a new hybrid on/off-line signature verification system is described, where the dynamic reference data is acquired by either a tablet or an instrumented pen and it is used to support the corresponding static signal (image). The signatures are segmented according to the complexity of their constituent strokes based upon

4. Acoustic monitoring – super sonics?
Vesicular breath sounds, wheezes, rhonchi, and crackles possess acoustic 'signatures' amenable to detection, quantification, and moment-by-moment visual display. Despite technical hurdles, new methods for sonic evaluation, once perfected, should offer innovative diagnostic and monitoring tools that add clinical value. These emerging options complement curren

5. Electroencephalographic signatures of attentional and cognitive default modes in spontaneous brain activity fluctuations at rest
We assessed the relation between hemodynamic and electrical indices of brain function by performing simultaneous functional MRI (fMRI) and electroencephalography (EEG) in awake subjects at rest with eyes closed. Spontaneous power fluctuations of electrical rhythms were determined for multiple discrete frequency bands, and associated fMRI signal modulations w

6. Discrimination among individual Watson–Crick base pairs at the termini of single DNA hairpin molecules
Nanoscale α-hemolysin pores can be used to analyze individual DNA or RNA molecules. Serial examination of hundreds to thousands of molecules per minute is possible using ionic current impedance as the measured property. In a recent report, we showed that a nanopore device coupled with machine learning algorithms could automatically discriminate among the fo

7. Optical Imaging of Molecular Signatures in Pulmonary Inflammation
Biomedical imaging has become an important tool in the study of “-omics” fields by allowing the noninvasive visualization of functional and molecular events using in vivo staining and reporter gene approaches. This capacity can go beyond the understanding of the genetic basis and phenotype of such respiratory conditions as acute bronchitis, adult respira

8. MitoProteome: mitochondrial protein sequence database and annotation system
MitoProteome is an object-relational mitochondrial protein sequence database and annotation system. The initial release contains 847 human mitochondrial protein sequences, derived from public sequence databases and mass spectrometric analysis of highly purified human heart mitochondria. Each sequence is manually annotated with primary function, subfunction a

9. Molecular Signatures of Self-Renewal, Differentiation, and Lineage Choice in Multipotential Hemopoietic Progenitor Cells In Vitro
The molecular mechanisms governing self-renewal, differentiation, and lineage specification remain unknown. Transcriptional profiling is likely to provide insight into these processes but, as yet, has been confined to “static” molecular profiles of stem and progenitors cells. We now provide a comprehensive, statistically robust, and “dynamic” analysi

10. Detection of secreted peptides by using hypothesis-driven multistage mass spectrometry
A method is presented for the rapid detection and characterization of trace amounts of peptides secreted from microorganisms, including pheromones, virulence factors, and quorum-sensing peptides. The procedure, based on targeted multistage MS, uses a novel matrix-assisted laser desorption/ionization-ion trap mass spectrometer to overcome limitations of curre

11. Secondary structure polymorphism in Oxytricha nova telomeric DNA
Tandem repeats of the telomeric DNA sequence d(T4G4) of Oxytricha nova are capable of forming unusually stable secondary structures incorporating Hoogsteen hydrogen bonding interactions. The biological significance of such DNA structures is supported by evidence of specific recognition of telomere end-binding proteins in the crystal state. To further charact
