We consider the problem of determining when two dataaow networks over uninterpreted nodes and some primitive nodes always have the same input-output behavior. We deene a set of behavior-preserving transformations on networks and show that this set is \schematologically complete", i.e., networks have the same input-output behavior under all interpretations if and only if they can be transformed ...

THE physician occasionally encounters a situation in clinical practice that offers unique opportunities to study physiologic principles relating to cardiac function that cannot be evaluated under ordinary circumstances. We recently studied a patient who had developed complete heart block without evidence of other cardiac or systemic disease. With heart rate controlled by an external pacemaker, ...

Background: A classical problem in metabolic design is to maximize the production of a desired compound in a given chemical reaction network by appropriately directing the mass flow through the network. Computationally, this problem is addressed as a linear optimization problem over the flux cone. The prior construction of the flux cone is computationally expensive and no polynomial-time algori...

In this paper, a novel method for interstage matching network design in the smith chart is presented. This technique is based on matching the reflection coefficients between input of interstage matching network and S22 of the first transistor with considering input VSWR and the gain of the complete amplifier (or output of the complete amplifier if the matching is applied to the output of the in...

AIMS To assess the determinants of exercise capacity and exercise oxygenation after atrial redirection for complete transposition. METHODS AND RESULTS At graded bicycle ergometry, including respiratory and arterial blood gas analyses, intra-arterial blood pressure recording, and cardiac output determination (dye-dilution technique), we tested 17 post-Mustard/Senning patients, 8.9-22.0 years o...

In this paper we consider systems which are globally completly observable and output-to-state stable. The former property guarantees the existence of coordinates such that the dynamics can be expressed in observability form. The latter property guarantees the existence of a state norm observer and therefore nonlinearities bounding function and local Lipschitz bound. Both allow us to build an ob...

The total factor productivity (TFP) of a multiple-output multiple-input firm can be defined as the ratio of an aggregate output to an aggregate input. With this definition, index numbers that measure changes in TFP can be expressed as the ratio of an output quantity index to an input quantity index. This paper uses the term multiplicatively complete to describe TFP index numbers that are constr...

This paper deals with concepts of output stability. Inspired in part by regulator theory, several variants are considered, which diier from each other in the requirements imposed upon transient behavior. The main results provide a comparison among the various notions, all of which specialize to input to state stability (iss) when the output equals the complete state.
