Abstract: We review how biological systems undertake signaling specifically examining, signal transduction and signaling via electrons and molecules. Key processes will be reviewed and important mathematical abstractions provided. With essential building blocks in place, several biological communication systems will be investigated including different modulation methods, associated demodulation strategies and network frameworks.
Two illustrative biological networks based on bacterial populations will be examined: electron transfer in bacterial filaments (multi-hopped bacterial networks) and the inducement of quorum sensing in homogeneous populations (multi-terminal bacterial networks). Queues are shown to be a simple, yet powerful method by which such systems can be modeled. Our initial models provide excellent match with experimental data. While the diffusion of chemical signals in the surrounding medium of biological systems has been heavily studied, the role of such processes is not fully understood in certain bacterial interactions. Our queuing models further suggest biologically relevant channel models for information theoretic analysis of larger systems. Our studies are motivated by the fact that microbial communities play a significant role in bioremediation, plant growth promotion, human and animal digestion, disease, elemental cycles, the carbon-cycle and maintaining clean water.

Laboratory for Information and Decision Systems (LIDS)
Abstract: The availability of positional information is of extreme importance in numerous wireless applications. The coming years will see the emergence of location-aware networks with sub-meter localization accuracy, minimal infrastructure, and high robustness in harsh (GPS challenged) environments. To reach this goal we advocate network localization and navigation, a new paradigm that exploits a combination of wideband transmission and spatiotemporal cooperation. Our work has addressed this problem from three perspectives: theoretical framework, cooperative algorithms, and network experimentation. This talk will provide an overview of our recent research results in this exciting field.

Abstract: Clustering techniques have been developed and applied in many areas for several decades. In particular, they have been used for gene clustering over the last two or three decades in bioinformatics and more recently in brain signal processing. New algorithms are being developed and applied to address many different problems. However, in applications with real data with little a priori knowledge, it is often difficult to select an appropriate clustering algorithm and evaluate the quality of clustering results due to the unknown ground truth. It is also the case that conclusions based on only one specific algorithm might be biased, since each algorithm has its own assumptions of the structure of the data, which might not correspond to the real data.
Another important issue relates to multiple datasets, which may have been generated either in the same laboratory or different laboratories at different times and with different settings though trying to conduct the similar experiments. In such a scenario, one has essentially a selection of heterogeneous datasets from similar experiments. The challenge is how to reach consensus conclusions in such scenarios.
This plenary presentation will address both of the aforementioned issues and discuss how Bi-CoPaM and UNCLES can solve both the issues. This presentation will include examples of results from some bioinformatics and brain signal processing, although these can be applied to all applications areas involving clustering.

Abstract: Monte Carlo (MC) methods are computational algorithms that were born in the field of physics more than sixty years ago. In the last 30+ years they have seen significant growth and their applications have spread to a wide range of disciplines. Their principal use is in problems that require optimization, numerical integration, and drawing samples from desired probability distributions.
Sequential Monte Carlo (SMC) methods are a class of MC methods that aim at estimating a hidden random process from an observed process that has information about the hidden process. SMC methods came to prominence two and a half decades ago and ever since have seen remarkable growth. Signal processing is an area where these methods have found highly fertile grounds for relevance, which is why the signal processing community is one of the driving forces in their further development. This presentation will address recent advances and current trends in the research of SMC methods. The emphasis will be on their application to complex problems where the unknowns are of high dimensions.
