  • Chapter 4 A Point for Thought: Why are Organisms Irreducible'
    • Abstract: 2008
      Publication year: 2008
      Source:Studies in Multidisciplinarity, Volume 6

      In the previous chapters I discussed the limits of reductionism and illustrated the limits of genetic reductionism. In this chapter, I present a novel argument for why organisms are irreducible. To present this argument, I begin by addressing a fundamental question: Why are there sign-mediated interactions in biology' According to Polanyi, biological hierarchies are constituted through boundary conditions. I argue that signs, or more accurately the processes of signification, function as these boundary conditions. Moreover, based on general insights from the physics of computation, I argue that the organism cannot be computed directly from DNA without the loss of critical information. In this context, signs as boundary conditions mediate biological construction in a way that prevents the loss of information and the destabilization of DNA.

    • Abstract: 2008
      Publication year: 2008
      Source:Studies in Multidisciplinarity, Volume 6

      In this chapter I aim to add another layer of complexity to our semiotic understanding of the genetic system and the poverty of reductionism. The issue I have chosen is the one of junk DNA. Non-codable DNA sequences were described as non-functional junk DNA. However, more and more evidence is being gathered about the different functions fulfilled by ncRNAs. In this chapter, I wish to consider ncRNAs as a part of a Meta-language. More specifically, I argue that every language or more generally, every system of signification must have a complementary meta-language (or a meta-system) for its functioning. In this context, the genetic realm is not an exception and the genetic “language” must be accompanied by a meta-language, which is (partially) materialized by the ncRNAs.

    • Abstract: 2008
      Publication year: 2008
      Source:Studies in Multidisciplinarity, Volume 6

      Immune specificity is usually described in terms of the lock-and-key metaphor. However, this metaphor is to a certain extent misleading and does not convey the complexity underlying immune specificity. The failure of the lock-and-key metaphor makes it difficult to understand immune specificity and recognition. This is the reason why immune specificity has been described as the specificity enigma. In this chapter, I point to three important differences between biological specificity and the mechanical specificity that underlies the lock-and-key metaphor. I further suggest an alternative lens through which immune specificity can be considered.

  • Chapter 8 A Point for Thought: Reflections on the Immune Self
    • Abstract: 2008
      Publication year: 2008
      Source:Studies in Multidisciplinarity, Volume 6

      The immune self is one of the main organizing concepts in immunology. However, it is not quite clear what the immune self is and heated debates have taken place among immunologists concerning the meaning and usefulness of this concept. In this chapter, I further illustrate the benefits of a meaning-making perspective and argue that the problem of the immune self can be approached as analogous to the problem of finding the different senses of the sign in semiotics. Following this suggestion, I would like to present the idea that the immune system is a meaning-making system and in this context to provide a novel conceptualization of the immune self that integrates several ideas from immunology and semiotics.

      Source:Studies in Multidisciplinarity, Volume 6

      Attempts to apply information in its syntactic sense to biology encounter the sharp criticism of irrelevance. Nevertheless, when biologists reflect on their subject matter they inevitably invite bridging concepts, such as information, the relevance of which is not always clear. In this chapter, it is suggested that meaning, rather than information, is the appropriate concept for biologists, not only because as a new organizing concept it introduces new research questions but also because, in contrast to information, it can bridge the physical–biological–semantic gap.

      In both natural language and biology, signs are polysemous, with a range of possible meanings before interaction-in-context determines their value. What is the meaning of polysemy' What is the role of polysemy in linguistic and biological systems' In this chapter, I present the idea that organisms function by using two different, orthogonal modes of communication: digital (involving discrete units) and analogue (involving continuous values). I argue that the polysemy of the sign, here metaphorically interpreted as a superposition, is necessary for orchestrating these modes and tying them to a concrete context of interaction.

  • Chapter 15 Recursive-Hierarchy: A Lesson from the Tardigrade
    • Abstract: 2008
      Publication year: 2008
      Source:Studies in Multidisciplinarity, Volume 6

      The tardigrade is a small microscopic creature that under environmental stress conditions undergoes cryptobiosis, a temporary metabolic depression, which is a third state between life and death. Cryptobiosis is an unexplained phenomenon. It is argued that this state is biologically obscure from a biological reductionist point of view, however, cryptobiosis makes sense within a different theoretical framework. The ability of the tardigrade to bootstrap itself is interpreted according to Gregory Bateson's idea of a recursive-hierarchy and a topological perspective on thermodynamics. It is argued that the structure of the organism is a recursive-hierarchical structure that allows the organism to conduct processes of reversible computations of which cryptobiosis is just a specific instance. The general meaning of this conclusion is discussed in the context of a scientific non-reductionist approach to biological systems and is used to illustrate the notion of a recursive-hierarchical system.

      It is common to think about the adaptive immune system as having a memory. However, memory is always accompanied by the complementary process of oblivion. Is there immune oblivion' In this chapter, I address this question from a meaning-making perspective and suggest that memorization and oblivion are two necessary and complementary processes for meaning making and for attuning us for the context of the here and now. I inquire the implications on this idea for understanding immune memory and immune deficiency among the elderly. This case will help us to better understand the meaning of context.

      Meaning making involves the ability to perceive beyond the particular and limited perspective of an observer. In this chapter, I discuss this ability—transgradience—from the perspectives of symmetry restoration and dimensionality reduction. We will find again that we are all unique but never alone and that semiosis is what allows us to read in between the lines of the book of life.

    • Abstract: 2008
      Publication year: 2008
      Source:Studies in Multidisciplinarity, Volume 5

      An overview of self-organisation in an archetypal nanostructured system—2D nanoparticle assemblies—is given. We first focus on the parallels that may be drawn for pattern formation in nanoscopic, microscopic, and macroscopic systems (spanning, for example, nanoparticle arrays, phase-separated polymers, diatom microskeletons, and binary fluid separation) before discussing the quantification of morphology and topology in nanostructured matter. The question of quantification is of key importance for the development of programmable or directed assembly and we highlight the central role that image morphometry can play in the software control of matter. The nanostructured systems we describe are, in very many cases, far from their ground state and we show that Monte Carlo simulations (based on the approach pioneered by Rabani et al. [Nature 426 (2003) 271]) provide important insights into the coarsening (i.e. approach to equilibrium) of nanoparticle arrays. We conclude with a consideration of the near-term prospects for programmable matter.

    • Abstract: 2008
      Publication year: 2008
      Source:Studies in Multidisciplinarity, Volume 5

      Biological systems at all scales self-assemble and maintain themselves in dynamic states away from thermodynamic equilibrium. Examination of various biological examples of dynamic self-assembly (DySA) enables one to extract general principles that govern it. These principles, in turn, can be applied to the rational design of artificial DySA systems by combining biological inspiration with the tools of chemistry, physics, and engineering. Such artificial DySA ensembles can be studied in quantitative detail and will ultimately lead to novel applications in biomimetic “smart” structures and materials.

  • Chapter 3 Computing by Self-Assembly: DNA Molecules, Polyominoes, Cells
    • Abstract: 2008
      Publication year: 2008
      Source:Studies in Multidisciplinarity, Volume 5

      We present three examples of computing processes where self-assembly (of parts into a complex structure) plays an essential role. The three examples have two things in common: all are based on the same old language-theoretical result (a characterization of recursively enumerable languages in terms of equality sets of morphisms), and all three provide characterizations of Turing computability. The first two cases are already known; one is based on DNA computing in terms of sticker systems, and one deals with a purely pictorial computing (computing with shapes). The third case deals with so-called population P systems: a few types of cells of small size are left to self-assembly (to spontaneously establish bonds among them), then the correct assemblages are checked (actually, they self-check), and if the process is successful (it halts), then a result is obtained in the form of the string of symbols sent into the environment.

      We introduce a new variant of dissipative particle dynamics (DPD) models that include the possibility of dynamically forming and breaking strong bonds. This model exhibits different forms of self-assembly processes; some like micelle formation involve only weak bonds, and others like the ligation of oligomers involve both weak and strong bonds. Complex self-assembly processes are notoriously difficult to design and program. We empirically demonstrate an evolutionary algorithm that optimizes self-assembly processes like micelle formation and template-directed ligation.

  • Chapter 5 Self-Assembly as an Engineering Concept across Size Scales
    • Abstract: 2008
      Publication year: 2008
      Source:Studies in Multidisciplinarity, Volume 5

      In this chapter we focus on systems made via self-assembly in the micrometer range or larger. Self-assembly at these size scales is important because although technological advances in the electronics industry continue to enable smaller, faster, cheaper, and more integrated systems, efforts in the area of integration have faced significant challenges in constructing 3D structures or building heterogeneous systems made of parts from incompatible microfabrication processes. Robotic “pick-and-place” techniques are currently used to integrate devices from many types of processes, but the ability to efficiently handle individual parts diminishes as the size scale of the components decreases below about 300 μm. Self-assembly is an attractive solution to overcome current integration limitations. Two micrometer-scale self-assembly systems are reviewed here: the first investigates the incorporation of single crystal silicon components, including single crystal silicon field effect transistors (FETs), on flexible plastic substrates for the construction of large area electronic systems, and the second system explores an avenue for future construction of three-dimensional silicon computing structures. The results from the first system include the electrical characterization of a self-assembled logic inverter, and the self-assembly of approximately 10,000 single crystal silicon elements in 25 minutes, each element measuring 100 μm in diameter.

  • Chapter 6 Probabilistic Analysis of Self-Assembled Molecular Networks
    • Abstract: 2008
      Publication year: 2008
      Source:Studies in Multidisciplinarity, Volume 5

      Several papers appeared recently on mapping computation onto nanofabrics with defect mapping followed by defect avoidance. However, such techniques are for permanent or manufacturing faults. Hence even after defect avoidance based configuration, the nanofabrics remain susceptible to natural operational faults. In this paper, we develop a probabilistic broadcast based defect map generation scheme suitable for self-assembled molecular nanofabrics. We also develop a hierarchical probabilistic design methodology to build fault-tolerant architectures on reconfigurable molecular nanofabrics using structural redundancy. We add various forms of redundancy to primitive structural elements and determine the appropriate levels of the hierarchy for insertion of such redundancy mechanisms. The effectiveness and scalability of the probabilistic toolset we have developed is also illustrated by evaluating the performance of our defect mapping scheme and by computing different critical design trade-offs.

  • Chapter 7 The “Programming Language” of Dynamic Self-Assembly
    • Abstract: 2008
      Publication year: 2008
      Source:Studies in Multidisciplinarity, Volume 5

      We show how protein dynamic self-assembly processes map naturally onto a formal model of computing, the random access machine (RAM), which is equivalent to a Turing machine. Specifically, we show that many biological processes that do not appear to be information processing, such as synthesis of macromolecules, structural assembly, transport, disassembly, and degradation of molecules, actually do perform computation when viewed from the RAM perspective. With this view that dynamic self-assembly processes are performing computation, we then look at this relationship from two perspectives. First, if self-assembly processes in living systems are performing computation, what algorithms are they carrying out' We discuss examples of algorithms implemented by living systems at multiple hierarchy levels. Second, if we can understand the “programming language” of dynamic self-assembly, can we design programs to self-assemble novel structures or materials' We give example computer simulations of programmed dynamic self-assembly of nanostructures.

    • Abstract: 2008
      Publication year: 2008
      Source:Studies in Multidisciplinarity, Volume 5

      This chapter summarizes current work on DNA-based self-assembly of computing systems. Section 2 presents a technology overview, specifically a discussion of nanoelectronic devices and desirable characteristics. It also describes two forms of DNA-based self-assembly (DNA-guided and DNA-scaffolded). Section 3 then discusses the limitations of the technology and the challenges this presents to the design of computer systems. Three case studies of computer architectures are presented in Section 4. A particular emphasis is placed on articulating how the architectures overcome the challenges of the self-assembly technology. We conclude in Section 5.

  • Chapter 9 Simulation of Self-Assembly Processes Using Abstract Reduction
           Systems
    • Abstract: 2008
      Publication year: 2008
      Source:Studies in Multidisciplinarity, Volume 5

      We present in this chapter the use of MGS for the abstract modeling and simulation of some self-assembly processes. MGS is a declarative and rule-based language dedicated to the modeling and the simulation of various morphogenetic and developmental processes. Such systems can be seen as dynamical systems but with a dynamical structure. This property is often exhibited by self-assembly processes. The MGS approach relies on the introduction of a topological point of view on various data structures called topological collections. This topological approach enables a uniform handling of these data structures by a new kind of rewriting rules called transformations. Using (local) rewriting rules to specify self-assembling processes is particularly adequate because it mimics closely the incremental building mechanism of the real phenomena. The MGS approach is illustrated on the fabrication of a fractal pattern, a Sierpinski triangle, using two approaches: by accretive growth and by carving. More generally, the notions of topological collections and transformations available in MGS enable the easy and concise modeling of cellular automata on various lattice geometries as well as more arbitrary constructions of multi-dimensional objects.

  • Chapter 10 Computer Aided Search for Optimal Self-Assembly Systems
    • Abstract: 2008
      Publication year: 2008
      Source:Studies in Multidisciplinarity, Volume 5

      DNA self-assembly is a promising paradigm for nanotechnology. In this chapter we study the problem of finding tile systems of minimum size that assemble a given shape in the Tile Assembly Model, defined by Rothemund and Winfree [Paul W.K. Rothemund, Erik Winfree, The program-size complexity of self-assembled squares (extended abstract), in: Proceedings of the Thirty-Second Annual ACM Symposium on Theory of Computing, ACM Press, 2000, pp. 459–468]. We present a tile system that assembles an N × ⌈ log 2 N ⌉ rectangle in asymptotically optimal Θ ( N ) time. This tile system has only 7 tiles. Earlier constructions need at least 8 tiles [A. Goel, H. Chen, Q. Cheng, P. Moisset de Espanés, Invadable self-assembly, combining robustness with efficiency, in: Proceedings of Symposium on Discrete Algorithms, ACM Press, 2004]. We managed to reduce the number of tiles without increasing the assembly time. The new tile system works at temperature 3. The new construction was found by the combination of exhaustive computerized search of the design space and manual adjustment of the search output. The search algorithms are of independent interest. We generalize the search techniques to look for tile systems that assemble non-rectangular shapes as well. In addition to the precise definition of the new counter, this chapter describes the design process, including the fortunate accidents that lead to its discovery.

  • Chapter 11 Programmable Self-Assembly—Theoretical Aspects and
           DNA-Linked Nanoparticles
    • Abstract: 2008
      Publication year: 2008
      Source:Studies in Multidisciplinarity, Volume 5

      We briefly present a method for the parameterization of assembly systems derived from their ability to form unique structures. The concept of bond uniqueness is introduced and we show how it influences the number of unique structures that a programmable, or algorithmic, self-assembly system can create. Further, we argue that programmable self-assembly systems create embedded, additional computation that is reflected in the complexity of the generated structures and show how this complexity is related to the bond uniqueness of the building blocks. A brief introduction to sticky graphs, a mathematical tool for modeling self-assembly systems, is given. From the theoretical discussions it becomes clear that building blocks for programmable self-assembly need to have at least four distinct, geometrically separated bonds. A scheme for the production of building blocks with well-directed bonds for programmable self-assembly using DNA-nanoparticles is presented. The introduced procedure is a completely bottom–up approach and can be used to produce quite advanced PSA building blocks like nanoparticle eight-mers with eight bonds. Initial experiments are presented.

           Patterns
    • Abstract: 2008
      Publication year: 2008

      Assembled large-scale systems of nano-particles or molecules can be represented by graphs (network structures), in which nodes and links have specified physical attributes. We consider two classes of complex spin-networks, in which spins with two degrees of freedom are attached to nodes of the network. We first demonstrate how different network geometries emerge when the microassembly rules and constraints are varied. We then study the dynamic response when these large-scale structures are driven by the magnetic field and show how the hysteresis curves and memory properties are affected by structural complexity of the underlying network.

  • Chapter 13 Automated Self-Assembling Programming
    • Abstract: 2008
      Publication year: 2008
      Source:Studies in Multidisciplinarity, Volume 5

      In this chapter we explore various facets of the interplay between natural computing and self-assembly as they pertain to automated self-assembling programming. In particular we focus on two complementary research issues, namely, the automated control and programming of model systems that self-assemble into specific configurations and, on the other hand, the use of self-assembling metaphors and model systems to implement new ways of performing computation. These “two sides of the self-assembly/computation coin” are tightly linked together, and advances in one of them could help to pave the way for advances in the other. Thus, we hope that this chapter will serve as an inspiration to other computer scientists to immerse themselves in the wealth of opportunities and problems begging for solutions [L. Adleman, Q. Cheng, A. Goel, M. Huang, D. Kempe, P. Moisset de Espanes, P.W.K. Rothemund, Combinatorial optimization problems in self-assembly, in: Proceedings of the Annual ACM Symposium on Theory of Computing (STOC), ACM Press, 2002], that self-assembly related research presents.
