Capacity Theorems for the Fading Interference Channel with a Relay and Feedback Links

Handling interference is one of the main challenges in the design of wireless networks. One of the key approaches to interference management is node cooperation, which can be classified into two main types: relaying and feedback. In this work we consider simultaneous application of both cooperation types in the presence of interference. We obtain exact characterization of the capacity regions for Rayleigh fading and phase fading interference channels with a relay and with feedback links, in the strong and very strong interference regimes. Four feedback configurations are considered: (1) feedback from both receivers to the relay, (2) feedback from each receiver to the relay and to one of the transmitters (either corresponding or opposite), (3) feedback from one of the receivers to the relay, (4) feedback from one of the receivers to the relay and to one of the transmitters. Our results show that there is a strong motivation for incorporating relaying and feedback into wireless networks.Comment: Accepted to the IEEE Transactions on Information Theor

Fenomenologia a projekt naturalizacji

[Phenomenology and the project of naturalization] In recent years more and more people have started talking about the necessity of reconciliating phenomenology with the project of naturalization. Is it possible to bridge the gap between phenomenological analyses and naturalistic models of consciousness? Is it possible to naturalize phenomenology? In their long introduction to the book Naturalizing Phenomenology published by Stanford University Press in 1999, the four co-editors, Jean Petitot, Francisco Varela, Bernard Pachoud, and Jean-Michel Roy set out to delineate what might be seen as a kind of manifesto for this new approach. An examination of this introduction is consequently a good starting point for a discussion of the issue

WHO\u27S GOING TO DANCE WITH SOMEBODY WHO CALLS YOU A MAIN STREETER COMMUNISM, CULTURE, AND COMMUNITY IN SHERIDAN COUNTY, MONTANA, 1918,1934

So began Logan\u27s long career in Sheridan County. The year was 1930, and she had just arrived from North Dakota, a fresh Cum Laude graduate of Jamestown College. The social and cultural walls that divided the community were at once unambiguously defined for her-with a simple list. The good Catholics and Lutherans of Plentywood made sure that the custodians of their children\u27s minds would be well insulated from the riffraff of the town-the liquor distillers, the bootleggers, and, of course, the reds. The social center of the community, the Farmer-Labor Templethe Red Temple to local conservatives-was generally off limits to Logan and her fellow teachers. The countless parties, dances, and celebrations held there were not to be part of their social life; that list guaranteed it. Emblazoned with hammers and sickles, the red flags that occasionally adorned the Temple marked for Plentywood\u27s teachers and their middleclass guardians-contemptuously referred to as mainstreeters by local left-wing criticsan ideological divide so immense as to be unbridgeable. Local communists were socially unacceptable, Bernadine Logan concluded, and anyway, who\u27s going to dance with somebody who calls you a mainstreeter

Consciousness, Self-consciousness, Selfhood:A reply to some critics

Review of Philosophy and Psychology has lately published a number of papers that in various ways take issue with and criticize my work on the link between consciousness, self-consciousness and selfhood. In the following contribution, I reply directly to this new set of objections and argue that while some of them highlight ambiguities in my (earlier) work that ought to be clarified, others can only be characterized as misreadings
