This work derives inner and outer bounds on the generalized degrees of freedom (GDOF) of the K-user symmetric MIMO Gaussian interference channel. For the inner bound, an achievable GDOF is derived by employing a combination of treating interference as noise, zero-forcing at the receivers, interference alignment (IA), and extending the Han-Kobayashi (HK) scheme to K users, depending on the number of antennas and the INR/SNR level. An outer bound on the GDOF is derived, using a combination of the notion of cooperation and providing side information to the receivers. Several interesting conclusions are drawn from the bounds. For example, in terms of the achievable GDOF in the weak interference regime, when the number of transmit antennas (M) is equal to the number of receive antennas (N), treating interference as noise performs the same as the HK scheme and is GDOF optimal. For K >; N/M+1, a combination of the HK and IA schemes performs the best among the schemes considered. However, for N/M <; K ≤ N/M+1, the HK scheme is found to be GDOF optimal.

This study assessed nearshore, marine ecosystem function around Trinidad and Tobago (TT). The coastline of TT is highly complex, bordered by the Atlantic Ocean, the Caribbean Sea, the Gulf of Paria and the Columbus Channel, and subject to local terrestrial runoff and regional riverine inputs (e.g. the Orinoco and Amazon rivers). Coastal organisms can assimilate energy from allochthonous and autochthonous Sources, We assessed whether stable isotopes delta C-13 and delta N-15 Could be used to provide a rapid assessment of trophic interactions in primary consumers around the islands. Filter-feeding (bivalves and barnacles) and grazing organisms (gastropods and chitons) were collected from 40 marine sites during the wet season. The flesh of organisms was analysed for delta C-13 and delta N-15. Results indicate significant variation in primary consumers (by feeding guild and sampling zone). This variation was linked to different energy Sources being assimilated by consumers. Results suggest that offshore production is fuelling intertidal foodwebs; for example, a depleted delta C-13 signature in grazers from the Gulf of Paria, Columbus Channel and the Caribbean and Atlantic coastline of 9 Tobago indicates that carbon with an offshore origin (e.g. phytoplankton and dissolved organic matter) is more important than benthic or littoral algae (luring the wet season. Results also confirm findings from other studies indicating that much of the coastline is subject to Cultural eutrophication. This Study revealed that ecosystem function is spatially variable around the coastline of TT, This has clear implications for marine resource management, as a single management approach is unlikely to be successful at a national level.

A general conclusion of the history of the Canadian press demonstrates that state was built after true journalism had been consolidating. Press development went along with economic progress and this was achievable, in great measure, because of the manner colonization took place in North America. This aided the de facto nationalization of press freedom in Canada. In Colombia, on the contrary, wealth concentration and the Spanish failure to build an economic market, resulted in a constant political instability from the time the Independence War. Legal and the de facto nationalization would be attained only at the end of the twentieth century, though journalism was already part of the institutional arrangement.-----Una conclusión general de la historia de la prensa canadiense demuestra que el estado actual se construyó después de haberse consolidado el verdadero periodismo. El desarrollo de la prensa fue paralelo al progreso económico y se pudo lograr en gran medida por la forma en que se colonizó Norteamérica. Esto ayudó a la nacionalización de facto de la libertad de prensa en Canadá. En Colombia, por el contrario, la concentración de la riqueza y el hecho de que los españoles no construyeran un mercado económico produjeron una inestabilidad política constante desde la época de la Guerra por la Independencia. La nacionalización legal y de hecho solamente se logró a finales del siglo XX, aunque el periodismo ya era parte de la organización institucional.
