Drawing from todaypsilas best-in-class solutions, we identify power-saving strategies that have succeeded in the past and look forward to new ideas and paradigms. We strongly believe that designing energy-efficient network equipment can be compared to building sports cars - task-oriented, focused and fast. However, unlike track-bound sports cars, ultra-fast(More)
To gain a better understanding of mycobacteria-host cell interaction, the present study compared the signal transduction events triggered during the interaction of Mycobacterium leprae (the causative agent of leprosy) and of Mycobacterium bovis BCG (an attenuated strain used as a vaccine against leprosy and tuberculosis) with human monocytes. The assays(More)
In photosynthetic organisms sulfate constitutes the main sulfur source for the biosynthesis of GSH and its precursor Cys. Hence, sulfur availability can modulate the capacity to cope with environmental stresses, a phenomenon known as SIR/SED (Sulfur Induced Resistance or Sulfur Enhanced Defence). Since chromate may compete for sulfate transport into the(More)
We study two optimization models for the network loading problem in the context of an access/aggregation network, i.e., the interface between the end user communicating to a cell site and the backbone network. The optimization models are applied to two scenarios of access/aggregation networks: one in which Ethernet ports are used and one in which MPLS ports(More)
