The evolution of communication in robot societies

Communication is fundamental to life on earth. All social organisms, from bacteria to humans, use communicative signals to coordinate their behaviors with members of their own and other species. Despite its key role in social organization, many questions r ...

The Evolution of Information Suppression in Communicating Robots with Conflicting Interests

Dario Floreano, Laurent Keller, Sara Mitri

Reliable information is a crucial factor influencing decision-making, and thus fitness in all animals. A common source of information comes from inadvertent cues produced by the behavior of conspecifics. Here we use a system of experimental evolution with ...

Inversion-based genomic signatures

Bernard Moret, Krister Swenson

Background: Reconstructing complete ancestral genomes (at least in terms of their gene inventory and arrangement) is attracting much interest due to the rapidly increasing availability of whole genome sequences. While modest successes have been reported fo ...

Temperature-dependent Fermi surface of 2H-TaSe2 driven by competing density wave order fluctuations

Helmuth Berger

Temperature evolution of the 2H-TaSe2 Fermi surface (FS) is studied by high-resolution angle-resolved photoemission spectroscopy. High-accuracy determination of the FS geometry was possible after measuring electron momenta and velocities along all high-sym ...

Phoneme Recognition Using Spectral Envelope and Modulation Frequency Features

Hynek Hermansky, Sriram Ganapathy, Samuel Thomas

We present a new feature extraction technique for phoneme recognition that uses short-term spectral envelope and modulation frequency features. These features are derived from sub-band temporal envelopes of speech estimated using Frequency Domain Linear Pr ...

Rapid parasite adaptation drives selection for high recombination rates

Marcel Salathé

The Red Queen hypothesis proposes that sex is maintained through selection pressure imposed by coevolving parasites: susceptible hosts are able to escape parasite pressure by recombining their genome to create resistant offspring. However, previous theoret ...

Effects of attentional focus on postural sway in children and adults

Estelle Palluel

The present study examined, in children aged 4-11 and in adults, the postural control modifications when attention was oriented voluntary on postural sway. Since (1) there are less attentional resources in children than in adults, (2) the selective attenti ...

Evolutionary Conditions for the Emergence of Communication in Robots

Dario Floreano, Stéphane Magnenat, Laurent Keller, Sara Mitri

Information transfer plays a central role in the biology of most organisms, particularly social species [1, 2]. Although the neurophysiological processes by which signals are produced, conducted, perceived, and interpreted are well understood, the conditio ...

Exploring Temperature-Aware Design of Memory Architectures in VLIW Systems

David Atienza Alonso, José Luis Ayala Rodrigo

This paper presents a thermal model to analyze the temperature evolution in the shared register files found on VLIW systems. The use of this model allows the analysis of several factors that have an strong impact on the heat transfer: layout topology, plac ...

Thermal Characterization and Thermal Management in Processor-Based Systems

David Atienza Alonso

The register file is one of the hottest devices in processor- based systems. Leakage reduction techniques and DTM mechanisms re- quire a thermal characterization of the hardware. This paper presents a thermal model to analyze the temperature evolution in t ...
