On stability and controllability of conjunctive Boolean networks
A Boolean network (BN) is a finite state discrete time dynamical system. At each step, each variable takes a value from a binary set. The value update rule for each variable is a local function which depends only on a selected subset of variables. BNs have been used in modeling gene regulatory …

The role of canalization in the spreading of perturbations in Boolean networks
Canalization is a property of Boolean automata that characterizes the extent to which subsets of inputs determine (canalize) the output. Here, we investigate the role of canalization as a characteristic of perturbation-spreading in random Boolean networks (BN) with homogeneous connectivity via …

NODE INFLUENCE IN NETWORK-BASED DISCRETE DYNAMICAL SYSTEMS
… a disease in an epidemiological network). These networks are frequently studied by analyzing global properties such as fixed points, robustness (sensitivity to perturbation), and functional organization (modularity). A fundamental problem in complex systems science is to understand how …

Algebraic theory for discrete models in systems biology
… yeast. Several discrete model types, such as Boolean networks, logical models, and bounded Petri nets, can be translated into the framework of PDS. Section 3 describes how to translate agent-based models into polynomial dynamical systems. Chapter 4, 5, and 6 are concerned with analysis of …

Emerging Design Methodology And Its Implementation Through Rns And Qca
… technology. Novel methodology for generating QCA Boolean circuits from multi-output Boolean circuits is presented. Our methodology takes as its input a Boolean circuit, generates simplified XOR-AND equivalent circuit and output an equivalent majority gate circuits. </p> <p>During the past decade, …

Computational aspects of cellular intelligence and their role in artificial intelligence.
… its underlying machinery - Cell Signalling Networks and the existing computational methods used to capture it are reported. The results of this search are then used to fashion the development of a versatile new connectionist representation, termed the Artificial Reaction Network (ARN). The …

Robustness Analysis of Gene Regulatory Networks
… First, the special topology of gene regulatory networks (GRNs) seems to be an important factor as they possess feedforward loops and certain other topological features much more frequently than expected. Second, genes often regulate each other in a canalizing fashion: there exists a dominance …
