We consider source coding over Aref networks. In particular we consider the following two problems: (i) multicasting correlated sources to a set of receivers, (ii) broadcasting sources to their respective receivers. For the first problem we show necessary ...
We study a problem motivated by cognitive radio in which the primary is a packet system that employs ARQ feedback. A secondary system is allowed to transmit in the same frequency band provided it ensures that the primary attains a specified target rate. Th ...

The present invention relates to a new family of mono, bis or tris (2,2'-substituted bipyridine) complexes of a metal selected amongst iron, ruthenium, osmium or vanadium, the bipyridine being substituted by at least one electron donor group. According to ...
We study two encodings of the asynchronous pi-calculus with input-guarded choice into its choice-free fragment. One encoding is divergence-free, but refines the atomic commitment of choice into gradual commitment. The other preserves atomicity, but introdu ...
This article presents a mathematical framework based on information theory to compare multivariate sensory streams. Central to this approach is the notion of configuration: a set of distances between information sources, statistically evaluated for a given ...
Performance limits for multiple-access channels are well known as long as the messages of different nodes are independent. Considerable research efforts have been devoted to the problem when the source information is dependent across nodes, revealing capac ...

Encoding correlated sources at separate encoders has been studied extensively from the perspective of asymptotically long block codes. The associated error exponents are known for the case of lossless source coding. In this paper, we introduce a novel tech ...

Finding sources of airborne chemicals with mobile sensing systems finds applications across the security, safety, domestic, medical, and environmental domains. In this paper, we present an algorithm based on source term estimation for odor source localizat ...
At the interface between solid surfaces and cavities filled with gaseous or liq. Xe, the nuclear magnetization of 131Xe (S = 3/2) is subject to quadrupolar interactions which may lead to higher rank single-quantum coherences that can be described by tensor ...
We briefly discuss the advanced characteristics of five new sources of synchrotron radiation that are being commissioned in the USA, Europe and Japan. Some of their applications in Biophysics and Biochemistry research are used to illustrate the revolution ...
