Long-term autonomy of robotic systems implicitly requires dependable platforms that are able to naturally handle hardware and software faults, problems in behaviors, or lack of knowledge. Model-based dependable platforms additionally require the application of rigorous methodologies during the system development, including the use of correct-by-con...

Robustness and evolvability are essential properties to the evolution of biological networks. To determine if a biological network is robust and/or evolvable, it is required to compare its functions before and after mutations. However, this sometimes takes a high computational cost as the network size grows. Here, we develop a predictive method to...

Robustness and evolvability are essential properties to the evolution of biological networks. To determine if a biological network is robust and/or evolvable, the comparison of its functions before and after mutations is required. However, it has an increasing computational cost as network size grows. Here we aim to develop a predictor to estimate...

Boolean networks are important models of biochemical systems, located at the high end of the abstraction spectrum. A number of Boolean gene networks have been inferred following essentially the same method. Such a method first considers experimental data for a typically underdetermined “regulation” graph. Next, Boolean networks are inferred by usin...

Article
Full-text available
Molecular regulation was initially assumed to follow both a unidirectional and a hierarchical organization forming pathways. Regulatory processes, however, form highly interlinked networks with non-hierarchical and non-unidirectional structures that contain statistically overrepresented circuits or motifs. Here, we analyze the behavior of pathways...

Molecular regulation was initially assumed to follow both a unidirectional and a hierarchical organization forming pathways. Regulatory processes, however, form highly interlinked networks with non-hierarchical and non-unidirectional structures that contain statistically overrepresented circuits (motifs). Here, we analyze the behavior of pathways c...

Background There are recent experimental reports on the cross-regulation between molecules involved in the control of the cell cycle and the differentiation of the vulval precursor cells (VPCs) of Caenorhabditis elegans. Such discoveries provide novel clues on how the molecular mechanisms involved in the cell cycle and cell differentiation processe...
Conference Paper
Boolean networks are important models of gene regulatory networks. Such models are sometimes built from: (1) a gene interaction graph and (2) a set of biological constraints. A gene interaction graph is a directed graph representing positive and negative gene regulations. Depending on the biological problem being solved, the set of biological const...
Conference Paper
The derivation of the Lagrangian for different configurations of spherical robots is explored through the use of the Euler Lagrange equations and additional constrains for the generalized velocities. The degrees of freedom are specified with rotation matrices and linear displacement vectors, allowing to determine the necessary elements for all the...
Conference Paper
Commonly, the design of a walking machine (WM) use to imitate the nature like multilegged creatures, which try to do the best approaching to a spider, a biped, quadruped or any other living animal. Trying to imitate the way that nature has generated animals seems to be more interesting and promising than imitating special results of the natural pro...
Conference Paper

Tactile texture recognition seems to be a very important research area with various interesting applications which include medical, geological and autonomous mobile robotics; despite the great amount of tasks that biological beings solve using the sense of touch, not much work is done in this area (except for pressure-related sensing), and there ar...

P. Kanerva's (1988) SDM classic model has been modified using a random memory space, whose qualities in two dimensions allow a significant reduction in the memory requirements of the modified net. The memory is managed in a space sharing mode; we present techniques that allow this kind of memory management, and we show that the operation of this ki...
