1. Otimização Unroll and Jam através da refatoração / Unroll and Jam optimization through refactoring
The optimizations of a program can be performed on the intermediate code, generated during compilation time, or through the Performance Refactoring that consists of insertion of optimizations directly in the source code of the application. In the source code structure, iteration loops have a major impact in the performance of the application because they are

2. A Methodology to explore the design space of memory hierarchies for embedded systems / Uma Metodologia para ExploraÃÃo do EspaÃo de Projeto de Hierarquias de MemÃria para Sistemas Embarcados
In platform tuning, memory hierarchy is an important element to be optimized. Many cache configurations need to be evaluated in order to find out the best choice in terms of performance, silicon area, or power consumption to an application. Most models to estimate those metrics depend on the cache size parameters and their respective miss rate. Instead of us

3. Olhares sobre uma cobertura: a eleição de 2002 para o governo do Paraná em três jornais locais
This thesis invited the journalists that worked covering Paraná government election of 2002 to talk about the experience, exercising a reflexion concerning their routines and work conditions. They were also encouraged to give an opinion about some major journalism themes, for example, objectivity, exemption, press freedom and the role that journalists have

4. Storage and management of similar images
Numerical images are becoming more and more important and an increasing emphasis on multimedia applications has resulted in large volumes of images. However, images need a large memory space to be stored, so their efficient storage and retrieval generate challenges to the database community. This paper proposes a new algorithm for an efficient storage of set

5. Competition for self-peptide-MHC complexes and cytokines between naïve and memory CD8+ T cells expressing the same or different T cell receptors
To study competition between naïve and memory T cells, we examined proliferation of adoptively transferred naïve CD8+ T cells in lymphopenic recipients or recipients containing a clonal population of CD8+ T cells. We find a hierarchy in the extent of T cell proliferation that appears to correlate with the strength of T cell receptor (TCR)-self-peptide-MHC

6. Sequence memory for prediction, inference and behaviour
In this paper, we propose a mechanism which the neocortex may use to store sequences of patterns. Storing and recalling sequences are necessary for making predictions, recognizing time-based patterns and generating behaviour. Since these tasks are major functions of the neocortex, the ability to store and recall time-based sequences is probably a key attribu

7. Differential Immunogenicity of Epstein-Barr Virus Latent-Cycle Proteins for Human CD4+ T-Helper 1 Responses
Human CD4+ T-helper 1 cell responses to Epstein-Barr virus (EBV) infection are likely to be important in the maintenance of virus-specific CD8+ memory and/or as antiviral effectors in their own right. The present work has used overlapping peptides as stimulators of gamma interferon release (i) to identify CD4+ epitopes within four EBV latent-cycle proteins,

8. A Test of Transitive Inferences in Free-Flying Honeybees: Unsuccessful Performance Due to Memory Constraints
We asked whether honeybees, Apis mellifera, could solve a transitive inference problem. Individual free-flying bees were conditioned with four overlapping premise pairs of five visual patterns in a multiple discrimination task (A+ vs. B-, B+ vs. C-, C+ vs. D-, D+ vs. E-, where + and - indicate sucrose reward or absence of it, respectively). They were then te

9. Measuring the diaspora for virus-specific CD8+ T cells
The CD8+ T cell diaspora has been analyzed after secondary challenge with an influenza A virus that replicates only in the respiratory tract. Numbers of DbNP366- and DbPA224-specific CD8+ T cells were measured by tetramer staining at the end of the recall response, then followed sequentially in the lung, lymph nodes, spleen, blood, and other organs.

10. Epitope Specificity and Relative Clonal Abundance Do Not Affect CD8 Differentiation Patterns during Lymphocytic Choriomeningitis Virus Infection▿
To evaluate the impact of immunodominance on CD8 T-cell properties, we compared the functional properties of dominant and subdominant populations in the response to lymphocytic choriomeningitis virus (LCMV). To improve functional discrimination, in addition to the usual tests of phenotype and function, we used a sensitive technique that allows the screening
