1. Información clásica e información cuántica: ¿dos tipos de información?
The aim of this article is to offer a conceptual analysis of the notion of information, on the basis of the way in which it is defined by the theories of Claude Shannon and of Benjamin Schumacher. Against the position according to which there are two kinds of information of different natures, a classical information and a quantum information (defined by the

2. O pretÃrito imperfeito do indicativo e as perÃfrases imperfectivas de passado em contos literÃrios escritos em espanhol: um estudo sociofuncionalista / Imperfective periphrasis of past and of imperfect of indicative tense in short stories by Spanish writers: a sociofunctional perspective
This dissertation studied the multifunctionality in a sociofunctional perspective of the imperfective past in the Spanish language in the contexts of use of imperfective periphrasis of past and of imperfect of indicative tense. It was also investigated the variation among these forms in the descriptive, habitual, desiderative and narrative functions. The obj

3. Contributions to the search methods of optimum trellis codes on new lattices partitioning / Contribuições aos metodos de procura dos codigos de treliça otimos sobre novas partições de reticulados
This thesis presents some contributions to the coded modulation schemes for the trellis codes based on lattices partitioning. One of the main contributions is the construction of the trellis codes based on novel lattices partitioning and also on chains partitioning. In order to optimize the search for the optimum trellis codes, a search algorithm was propose

4. On the infrared behavior of Green's functions in Yang-Mills theory
Non-perturbative properties of QCD, such as color confinement, are encoded in the infrared behavior of correlation functions, e.g. propagators and vertices. Various analytic predictions have been suggested for these quantities in various gauges. Here we numerically test these predictions using lattice gauge theory. In particular, we present results for the 2

5. "Idoso institucionalizado e a compreensÃo do seu cotidiano" / Institutionalized elderly people and the understanding of his daily routine
When entering a rest home, many elders face one of its main features: the totalitarian nature of these institutions. Thus, it is necessary for them to adapt themselves to a new routine full of rules. Now they need, after spending their whole life living with people to whom theyâve had blood relation and friendship ties, to learn to live with completely unkn

6. Scalable automated proving and debugging of set-based specifications
We present a technique to prove invariants of model-based specifications in a fragment of set theory. Proof obligations containing set theory constructs are translated to first-order logic with equality augmented with (an extension of) the theory of arrays with extensionality. The idea underlying the translation is that sets are represented by their characte

7. Repensando a interface sintaxe-fonologia a partir do axioma de correspondencia linear
This dissertation deals with the syntax-phonology interface. The theoretical framework consists of two complementary theories: the Minimalist Program (Chomsky 1993, 1994, 1995; Kayne 1994) &the Theory of Prosodic Hierarchy (Selkirk 1984, 1986; Nespor &Vogel 1986; Inkelas &Zec 1990). Here I make the following claims: (i) By taking the base &the recursive step

8. Optimal protein-folding codes from spin-glass theory.
Protein-folding codes embodied in sequence-dependent energy functions can be optimized using spin-glass theory. Optimal folding codes for associative-memory Hamiltonians based on aligned sequences are deduced. A screening method based on these codes correctly recognizes protein structures in the "twilight zone" of sequence identity in the overwhelming majori

9. Testing a biosynthetic theory of the genetic code: Fact or artifact?
It has long been conjectured that the canonical genetic code evolved from a simpler primordial form that encoded fewer amino acids [e.g., Crick, F. H. C. (1968) J. Mol. Biol. 38, 367–379]. The most influential form of this idea, “code coevolution” [Wong, J. T.-F. (1975) Proc. Natl. Acad. Sci. USA 72, 1909–1912], proposes that the genetic code c

10. Frequency encoding in excitable systems with applications to calcium oscillations.
A number of excitable cell types respond to a constant hormonal stimulus with a periodic oscillation in intracellular calcium. The frequency of oscillation is often proportional to the hormonal stimulus, and one says that the stimulus is frequency encoded. Here we develop a theory of frequency encoding in excitable systems and apply it to intracellular calci

11. Similarity between the corticotropin (ACTH) receptor and a peptide encoded by an RNA that is complementary to ACTH mRNA.
An interesting pattern in the genetic code was recently observed: Codons for hydrophilic and hydrophobic amino acids on one strand of nucleic acid are complemented by codons for hydrophobic and hydrophilic amino acids on the other strand, respectively. The average tendency of codons for "uncharged" (slightly hydrophilic) amino acids is to be complemented by

12. Nucleotide sequence of a gene from chromosome 1D of wheat encoding a HMW-glutenin subunit.
A high molecular weight glutenin gene in hexaploid wheat has been isolated by cloning in bacteriophage lambda and characterized. The gene corresponds to polypeptide 12 encoded by chromosome 1D in the variety "Chinese Spring". The coding sequence predicted contains seven cysteine residues six of which flank a central repetitive region comprising more than 70%
