    abstract={Akyildiz et al. envisioned the use of nanonetworks as a new paradigm for computation and communication on a very small scale. We present a new approach to implement nanonetworks with molecular communication using tile-based self-assembly systems on the basis of DNA. In this model, the medium of communication is filled with DNA-based molecules. Furthermore, some nanobots are capable of creating or releasing said molecules. Once present, they can be detected by other nanobots and interpreted as messages. Some DNA-based molecule systems are capable of universal computation. We show that it is possible to construct systems, in which the evaluation to true of an arbitrary decision problem is a precondition for the assembly of a message molecule. We relocate computations from nanobots into message molecules, thereby revolutionizing the paradigm for computation in nanonetworks. This approach can be interpreted as computation inside the communication channel. We further present message molecules that only assemble if a marker has been detected at least k times, as a proof of concept.}

    ADDRESS={Reykjavik, Iceland},
    KEYWORDS={Nanonetworks; Simulation; Medical Application; Nano medicine,NCN},
    ABSTRACT={The simulation of nanobots in their working environment is crucial to
    promote their application in the medical context. Several simulators for
    nanonetworks investigate new communication paradigms at nanoscale. However,
    the influence of the environment, namely the human body, on the movement
    and communication of nanobots was not considered so far. We propose a
    framework for simulating medical nanonetworks, which integrates a
    nanonetwork simulator with a body simulator. We derive requirements for a
    body model that forms the basis for our prototypical implementation of the
    body simulator BloodVoyagerSas part of the network simulator ns-3. An
    evaluation shows that BloodVoyagerS successfully moves nanobots in the
    simulated cardiovascular system. After about 7 minutes, the nanobot
    distribution reaches a dynamic equilibrium. The prototype shows promise to
    provide a more realistic full-body simulation to investigate movement and
    communication of nanobots in medical applications.}

     abstract = {Statistical and biochemical studies of the standard genetic code (SGC) have found evidence that the impact of mistranslations is minimized in a way that erroneous codes are either synonymous or code for an amino acid with similar polarity as the originally coded amino acid. It could be quantified that the SGC is optimized to protect this specific chemical property as good as possible. In recent work, it has been speculated that the multilevel optimization of the genetic code stands in the wider context of overlapping codes. This work tries to follow the systematic approach on mistranslations and to extend those analyses to the general effect of frameshift mutations on the polarity conservation of amino acids. We generated one million random codes and compared their average polarity change over all triplets and the whole set of possible frameshift mutations. While the natural code—just as for the point mutations—appears to be competitively robust against frameshift mutations as well, we found that both optimizations appear to be independent of each other. For both, better codes can be found, but it becomes significantly more difficult to find candidates that optimize all of these features—just like the SGC does. We conclude that the SGC is not only very efficient in minimizing the consequences of mistranslations, but rather optimized in amino acid polarity conservation for all three effects of code alteration, namely translational errors, point and frameshift mutations. In other words, our result demonstrates that the SGC appears to be much more than just “one in a million”.}
