Slide 1

“What I can\'t make I don\'t understand”: The parallel synergistic pathways of configuration and revelation Michael L. Simpson Center for Nanophase Materials Sciences, Oak Ridge National Laboratory, Oak Ridge, TN 37831 Materials Science and Engineering Department, The University of Tennessee, Knoxville, TN 37996 NSF Workshop on Molecular Communication: Biological Communications Technology February 20-21, 2008

Slide 2

Grand Challenges DOE – BES as of late discharged rundown of ‘grand challenges”

Slide 3

Biological frameworks 4B years of brutal companion audit Scale (thickness), Complexity (network) Components Complexity in capacity for the most part involves multifaceted nature in the wiring….

Slide 4

Understand Design Questions for S2 How do organic elements impart? How is natural data encoded onto and decoded from atoms? What are the repeating architectures of organic correspondences? What are the heartiness delicacy exchange offs in natural correspondences frameworks? In what manner can diverse organic frameworks be interfaced to upgrade correspondence? How might correspondence components utilized by organic elements be connected to make a manufactured correspondence framework utilizing natural materials?

Slide 5

Understand Design This discussion What is the framework environment? Past 1 st close estimations Information scene (commotion is all around) Communicating in a group Architectures that have advanced in this environment Bow ties, power, and delicacy Poster tyke for organic correspondences, majority detecting With inadequate learning, how would we outline in this environment? Top-down Bottom-up

Slide 6

Transmitter Receiver Channel gene1 gene2 From a frameworks view correspondence has three fundamental players First request rough guesses – framework wide high devotion Transmitter encodes with high loyalty (collector translates) data in size or condition of an atomic populace/fixation There is no ‘uncertainty’ in the data Free dispersion of data through a quiet channel Activity of gene2 straightforwardly relative to movement of gene1 (e.g. Slope expression)

Gene P mRNA rot commotion k R Transcription clamor * mRNA k P Translation clamor Protein rot clamor * Protein Noise is all over the place Poisson forms σ 2 = <M> Gene expression is bursty σ 2 ~ b<M> Transcriptional control is much noisier than Hill energy demonstrates Extrinsic commotion Correlated commotion that couples into all quality circuits Is commotion dependably ‘bad’? May pass on the genuine instability in data Exists in the setting of an exceptionally organized complex framework what are the ‘systems’ properties of commotion?

Slide 9

broad take a gander at clamor Noise in yeast proteins Noise structure is more mind boggling Noise is 2-d: (size of changes); and connection (length of time of variances) High populace & high commotion? Why? Simpson, et al., Proc. Nat. Acad. Sci. 100 , 4551-4556 (2003). Austin, et al. Nature , 439 , 608-611 (2006). Bar-Even, et al., Nat Genet , 38 , 636-643 (2006). Newman, et al. Nature , 441 , 840-846 (2006).

Slide 10

C onservation and conveyance of stochasticity Fundamental inquiry: How ought to stochasticity be dispersed and directed Uniformly appropriated? Dispersed by capacity sort? Is stochasticity constantly minimized? However, Is limited ~50M atoms, couple of thousand distinct proteins Total stochasticity is saved, yet it can be unequally dispersed over the segments
