Task-dependent influence of genetic architecture and mating frequency on division of labour in social insect societies
Dario Floreano, Laurent Keller
Division of labour is one of the most prominent features of social insects. The efficient allocation of individuals to different tasks requires dynamic adjustment in response to environmental perturbations. Theoretical models suggest that the colony-level ...
Springer Verlag2010Evolution in heterogeneous populations From migration models to fixation probabilities
Séverine Vuilleumier Varisco, Nicolas Perrin
Although dispersal is recognized as a key issue in several fields of population biology (such as behavioral ecology population genetics metapopulation dynamics or evolutionary modeling) these disciplines focus on different aspects of the concept and often ...
Elsevier2010Fair Welfare Maximization
Thomas Alois Weber, Ashish Goel
We consider the general problem of finding fair constrained resource allocations. As a criterion for fairness we propose an inequality index, termed “fairness ratio,” the maximization of which produces Lorenz-undominated, Pareto-optimal allocations. The fa ...
Springer Verlag2009Parasites lead to evolution of robustness against gene loss in host signaling networks
Many biological networks can maintain their function against single gene loss. However, the evolutionary mechanisms responsible for such robustness remain unclear. Here, we demonstrate that antagonistic host-parasite interactions can act as a selective pre ...

Florian Maria Wurm, Gaurav Backliwal, Sébastien Chenuet, Sarah Wulhfard
Transient transfection allows for fast production of recombinant proteins. However, the current bottlenecks in transient transfection are low titers and low specific productivity compared to stable cell lines. Here, we report an improved transient transfec ...
2008Wireless Network Secrecy with Public Feedback
Emre Telatar, Suhas Diggavi, Etienne Perron
In this paper we consider secret communication between two special nodes ("source" and "destination") in a wireless network with authenticated relays: the message communicated to the destination is to be kept information-theoretically (unconditionally) sec ...

Paolo De Los Rios, Francesco Piazza, Cécile Caretta Cartozo
The identification of cell cycle-related genes is still a difficult task, even for organisms with relatively few genes such as the fission yeast. Several gene expression studies have been published on S. pombe showing similarities but also discrepancies in ...
Public Library of Science2007An Analysis of Database System Performance on Chip Multiprocessors
Anastasia Ailamaki, Babak Falsafi, Frederick Ryan Johnson, Ippokratis Pandis
Prior research shows that database system performance is dominated by off-chip data stalls, resulting in a concerted effort to bring data into on-chip caches. At the same time, high levels of integration have enabled the advent of chip multiprocessors and ...
2007Using Highly Discriminative Keys for Indexing in a Peer-to-Peer Full-Text Retrieval System
Karl Aberer, Martin Rajman, Vinh Toan Luu, Fabius Klemm
Excessive network bandwidth consumption, caused by the transmission of long posting lists, was identified as one of the major bottlenecks for implementing distributed full-text retrieval in a Peer-to-Peer (P2P) architecture. To address this problem we intr ...
