Structure, characterization and near-infrared emission of a novel 6-connected uninodal 3D network of Nd(III) containing 2,5-thiophenedicarboxylate anion

The novel coordination polymer with the formula {[Nd2(2,5-tdc)3(dmf)2(H2O)2].dmf.H2O}n (2,5-tdc2-=2,5-thiophedicarboxylate anion and dmf=dimethylformamide) has been synthesized and characterized by thermal analysis (TG/DTA), vibrational spectroscopy (FTIR) and single crystal X-ray diffraction analysis (XRD). Structure analysis reveals that Nd(III) ions show dicapped trigonal prism coordination geometry. The 2,5-tdc2- ligands connect four Nd(III) centers, adopting (κ1 - κ1) - (κ1 - κ1) - μ4 coordination mode, generating an interesting 6-connected uninodal 3D network. Photophysical properties were studied using diffuse reflectance spectroscopy (DR) and excitation/emission spectra. The photoluminescence data show the near infrared emission (NIR) with the characteristic 4F3/2→4IJ (J=9/2, 11/2 and 13/2) transitions of Nd(III) ion, indicating that 2,5-tdc2- is able to act as a sensitizer for emission in NIR region. © 2013 Elsevier B.V.

Next-generation sequencing reveals large connected networks of intra-host HCV variants

Background: Next-generation sequencing (NGS) allows for sampling numerous viral variants from infected patients. This provides a novel opportunity to represent and study the mutational landscape of Hepatitis C Virus (HCV) within a single host.Results: Intra-host variants of the HCV E1/E2 region were extensively sampled from 58 chronically infected patients. After NGS error correction, the average number of reads and variants obtained from each sample were 3202 and 464, respectively. The distance between each pair of variants was calculated and networks were created for each patient, where each node is a variant and two nodes are connected by a link if the nucleotide distance between them is 1. The work focused on large components having > 5% of all reads, which in average account for 93.7% of all reads found in a patient. The distance between any two variants calculated over the component correlated strongly with nucleotide distances (r = 0.9499; p = 0.0001), a better correlation than the one obtained with Neighbour-Joining trees (r = 0.7624; p = 0.0001). In each patient, components were well separated, with the average distance between (6.53%) being 10 times greater than within each component (0.68%). The ratio of nonsynonymous to synonymous changes was calculated and some patients (6.9%) showed a mixture of networks under strong negative and positive selection. All components were robust to in silico stochastic sampling; even after randomly removing 85% of all reads, the largest connected component in the new subsample still involved 82.4% of remaining nodes. In vitro sampling showed that 93.02% of components present in the original sample were also found in experimental replicas, with 81.6% of reads found in both. When syringe-sharing transmission events were simulated, 91.2% of all simulated transmission events seeded all components present in the source.Conclusions: Most intra-host variants are organized into distinct single-mutation components that are: well separated from each other, represent genetic distances between viral variants, robust to sampling, reproducible and likely seeded during transmission events. Facilitated by NGS, large components offer a novel evolutionary framework for genetic analysis of intra-host viral populations and understanding transmission, immune escape and drug resistance.

A implantação da televisão digital terrestre na Espanha

This monograph has as objectives introduce digital terrestrial television, describing the process of installation of this in Spain, their technical qualities and possibilities of change and innovation that this creates. The exposure of the different chapters of this monograph has a objective presenting and discussing what are the characteristics of this new technology, your birth, what is its importance in communication and how this is inserted inside the Spanish reality. The introduction of digital terrestrial television in Spain is cited as an example of a pioneer in the development and installation of this new technology, but also appears as a nation that has come a way with some economic failures, reaching one of the largest cases of delayed installation of digital television in Western Europe. Making use of the European system for digital terrestrial television (DVB-T - Digital Video Broadcasting) it was possible some advances as the quality of communication and strengthening national public television system, but many vices of analog system were transferred this new system, as the concentration of channels to a foreign group and interactivity opportunities were wasted. Digital terrestrial television can provides better picture quality and sound, possibility of interactivity, mobility, hypermedia and multiprogramming, while the latter tool may lead to the democratization of media, opening it to other social agents. Going much further than just a technological advancement, digital television is strongly connected with the politics and the economy of the nation in which it operates

Interação humano-tv digital (IHTVD) e interatividade

With the development of Digital TV, the equipments are becoming more and more modernized in order to popular- ize the information that soon might reach all Brazilian families. That way, we open a space for discussion about the many directions that the usability applied on ISDB-Tb interactivity (Brazilian System of Digital Television) can take. This paper approaches the questions connected to the concept of usability and also the subjects related to the life cycle of some technologies (existence time, obsolescence) Also talks with the definition of interactivityon Digital Television since it is responsible for the emergence of a new contingent of interacting people which goes from the computer and portable equipments users to the passive TV viewers. It’s possible to conclude that the Human-Digital TV Interaction (HDTVI) comprehends the synergy between three actants on Digital TV: the col- lective (or not) TV viewer; the interface and the issuer who can be represented by an Artificial Intelligence (AI) service.

TV digital interativa no Brasil: até quando esperar?

The ideal proposed by Decree No. 4901 of 26 November 2003 establishing the Brazilian System of Digital Television (SBTVD) still seems more remote from reality as possible in 2003, where it was believed more in digital inclusion (and social) through access Digital TV via internet than to the development of specifi c products for this media. The reality still shows up differently and it is possible to believe that there was an innocent vision and too optimistic a project that did not meet even the demands of society: SBTVD. The problem to be solved is to get Digital TV adds value to the needs of today’s consumers of content, space has been occupied quickly by computers and devices connected to the internet and even the informal trade of DVDs and video games.
