1. ESTIMATING THE DEMAND FOR BROADBAND SERVICES IN BRAZIL: ANALYSIS BY A DISCRETE-CHOICE MODEL
RESUMO A análise empírica estima a demanda por banda larga fixa residencial no Brasil por meio do modelo de escolha discreta Nested Logit. Os resultados indicam que a demanda é elástica. A elasticidade preço da demanda é maior para os municípios que contam com mais de um grupo econômico ofertando banda larga. Esse resultado é intuitivo na medida que

2. Seismic Performance of Cable-sliding Modular Expansion Joints Subject to Near-fault Ground Motion
AbstractAccording to the research fruits of the diverse damages of bridge in the past, bearings' invalidation is the main reason of the damage of isolated bridges and causes oversized relative displacements between pier and girder. Eventually, it may lead to severe collision of superstructure. It is extremely dangerous when near-fault motion occurs, because

3. Clinicopathological significance of PTPN12 expression in human breast cancer
Protein tyrosine phosphatase non-receptor type 12 (PTPN12) is a recently identified tumor suppressor gene (TSG) that is frequently compromised in human triple-negative breast cancer. In the present study, we investigated the expression of PTPN12 protein by patients with breast cancer in a Chinese population and the relationship between PTPN12 expression leve

4. Modelagem de redes CDMA-PON baseadas em técnicas de cancelamento paralelo e códigos corretores de erros / Modeling of CDMA-PON networks using parallel interference cancellation and error correcting codes techniques
The advent of new services offered to end users, such as the so called triple play, which consists in the simultaneous traffic of voice, video, and data through the same communication infrastructure, has been pushing telecom operators towards providing adequate bandwidth as well as quality of service. This has brought the spotlight to passive optical network

5. Analisando a viabilidade da aplicação triple play para a inclusão digital, utilizando a tecnologia Wimax / Analyzing the viability for the application of triple play for digital inclusion using a WiMAX technology
Inclusão Digital é hoje um tema de muita preocupação, principalmente nos países denominados emergentes. No Brasil existem diversas iniciativas e experiências relativas a esse assunto, tanto por parte dos governos (Federal, Estadual e Municipal), como também por parte de ONGs e empresas privadas. O acesso à Internet Banda Larga a baixo custo tem sido

6. Descrição e proposição de uma solução de IPTV / Description and proposal of an end-to-end IPTV solution
This works concerns the study and the analysis of an IPTV solution (Internet Protocol Television). This kind of service is emerging in the Telco all over the world and its good acceptance is radically changing the business vision of the telecommunications providers. Final consumers will demand personalized services using multiple devices including TV channel

8. Stability of triple helices containing RNA and DNA strands: experimental and molecular modeling studies.
UV-absorption spectrophotometry and molecular modeling have been used to study the influence of the chemical nature of sugars (ribose or deoxyribose) on triple helix stability. For the Pyrimidine.purine* Pyrimidine motif, all eight combinations were tested with each of the three strands composed of either DNA or RNA. The chemical nature of sugars has a drama

9. Cortical dysplasia resembling human type 2 lissencephaly in mice lacking all three APP family members
The Alzheimer's disease β-amyloid precursor protein (APP) is a member of a larger gene family that includes the amyloid precursor-like proteins, termed APLP1 and APLP2. We previously documented that APLP2−/−APLP1−/− and APLP2−/−APP−/− mice die postnatally, while APLP1−/−APP−/− mice and single mutants were viable. We now report that m

10. Unique condensation patterns of triplex DNA: physical aspects and physiological implications
Triple-stranded DNA structures can be formed in living cells, either by native DNA sequences or following the application of antigene strategies, in which triplex-forming oligonucleotides are targeted to the nucleus. Recent studies imply that triplex motifs may play a role in DNA transcription, recombination and condensation processes in vivo. Here we show t

11. Multiple Formate Dehydrogenase Enzymes in the Facultative Methylotroph Methylobacterium extorquens AM1 Are Dispensable for Growth on Methanol
Formate dehydrogenase has traditionally been assumed to play an essential role in energy generation during growth on C1 compounds. However, this assumption has not yet been experimentally tested in methylotrophic bacteria. In this study, a whole-genome analysis approach was used to identify three different formate dehydrogenase systems in the facultative met

12. Analysis of Flowering Time Control in Arabidopsis by Comparison of Double and Triple Mutants1
Three genetic pathways promote flowering of Arabidopsis under long photoperiods. These pathways are represented by the genes CO, FCA, and GA1, which act in the long-day, autonomous, and gibberellin pathways, respectively. To test whether these are the only pathways that promote flowering under long photoperiods, the co-2 fca-1 ga1-3 triple mutant was constru
