This paper concerns the transmission of two independent Gaussian sources over a two-user decentralized interference channel, assuming that the transmitters are unaware of the instantaneous CSIs. The availability of the channel state information at receivers (CSIR) is considered in two scenarios of perfect and imperfect CSIR. In the imperfect CSIR case, we consider a more practical assumption of...

Although the forces behind the evolution of imperfect mimicry remain poorly studied, recent hypotheses suggest that relaxed selection on small-bodied individuals leads to imperfect mimicry. While evolutionary history undoubtedly affects the development of imperfect mimicry, ecological community context has largely been ignored and may be an important driver of imperfect mimicry. Here we investi...

It is widely known that our closest relatives, the great apes, which hold some of the potentially richest genetic insights into our own evolution, are under threat in their natural environments. But a new assessment of our only Asian cousin, the orangutan, by the Worldwide Fund for Nature suggests numbers have declined by 90 per cent over the past century and that extinction in the wild may occ...

This article presents a unified solution to two long-standing problems concerning successive cyclicity. First, under the minimalist program of Chomsky (1995), a trigger for successive-cyclic wh-movement to [–wh] SpecC positions must be identified. Second, as noted by den Besten & Webelhuth (1990), there is a strict prohibition against unbound intermediate traces that result from a combination o...

This paper presents a theoretical view of imperfect market. It concludes that an increase in the price of products does not give any incentive to increasing production which shows the mechanism for upward trends in prices.

As large-scale wireless networks continue to proliferate, a reliable way to test coverage and communicate requirements becomes increasingly important. In this paper we discuss concerns and provide guidelines to consider when developing a coverage testing methodology for large-scale wireless networks. We propose a method which complies with these guidelines and apply it to a large municipal mesh...
