Allosteric enzyme models and their analysis by the theory of graphs

Biochimica et Biophysica Acta (BBA) - General Subjects, 1966
Abstract Possible cooperative models, intended for the description of the properties of allosteric enzymes, have been studied for the simplest case of the dimeric protein. Both the “indirect” cooperativity used by Monod et al , 1 and the “direct” cooperativity determined by the direct interaction of active sites have been investigated.

Evidence that robot-assisted gait training modulates neuroplasticity after stroke: An fMRI pilot study based on graph theory analysis.

Brain Research
OBJECTIVES To investigate alterations of whole-brain network after stroke and therapeutic mechanisms of robot-assisted gait training (RAGT). METHODS 21 S patients and 20 healthy subjects were enrolled, with the stroke patients randomized to either ...

Graph theory in the analysis of nonlinear systems

IEEE Transactions on Automatic Control, 1966
Graph techniques together with the nonharmonic series representation of stationary Gaussian signals can be used in the analysis of a wide class of nonlinear systems. This point is illustrated by the derivation of the moments of a nenlinear functional of a Gaussian signal.

On Applying Graph Theory to ILP Analysis

IEEE Latin America Transactions, 2006
The evaluation of computer architectures requires new tools that complement the customary simulations. Graph theory can help to create a new frame of fine grain parallelism analysis. The differences found between the superscalar performance in x86 and non-x86 processors and the peculiar characteristics of the x86 instruction set architecture recommend ...

DIRECTED GRAPH THEORY AND THE ECONOMIC ANALYSIS OF INNOVATION

Metroeconomica, 1995
ABSTRACTThis article applies digraph theory to the theory of technological regimes. The first part of the paper identifies a number of links between the evolutionary approach and a particular version of the neoclassical approach to the economic analysis of technological change.

A Graph Theory Approach to Demographic Loop Analysis

Ecology, 1998
A demographic analysis of the life-cycle graph can be used to quantify the separate contributions of different life-history types to the population growth rate. Loop analysis has been proposed (van Groenendael et al. 1994) as the appropriate method for partitioning the elasticity matrix to determine these contributions.

ANALYSIS OF COLLABORATIVE NETWORKS USING THE EXTREMAL GRAPH THEORY

IFAC Proceedings Volumes, 2006
Abstract In literature, a large number of studies on the Italian districts exhibit a portrait which points out the Italian economic specificity. A specific feature of the Italian districts is the large number of collaborative actions carried on by the associated enterprises which are not limited to the usual supply chain management problems.

The structure of electrical networks: a graph theory based analysis

International Journal of Critical Infrastructures, 2009
We study the vulnerability of electrical networks through structural analysis from a graph theory point of view. We measure and compare several important structural properties of different electrical networks, including a real power grid and several synthetic grids, as well as other infrastructural networks.

A graph theory analysis of renal glomerular microvascular networks

Microvascular Research, 2004
A graph theory model and its invariants are used to compare previously published renal glomerular networks of six adult rats, one adult uremic rat, and one newborn rat. Invariants calculated include order, size, cycle rank, eccentricity, root distance, planarity, and vertex degree distribution. These invariants enabled the differentiation of six normal
