New parameter for QRS complex low voltage in chagasic cardiomyopathy: the ADOC index [PDF]

Revista da Sociedade Brasileira de Medicina Tropical
Background: Low QRS complex voltage is an important predictor of death in Chagas disease. However, the parameters applied to the low-voltage classification were described by the Minnesota Code and not specifically for Chagas disease.

On the Acquisition of English Complex Predicates and Complex Word Formation: Revisiting the Parametric Approach

Languages
Languages vary in their availability of productive endocentric bare-stem compounds (e.g., flower hat) and a range of complex predicates (separable verb-particles, double object datives, adjectival resultatives, put-locatives, make-causatives, and ...

Complex Methodology for Parameter Optimization of Dynamic Injection Regulator Ad- justment

Известия высших учебных заведений и энергетических объединенний СНГ: Энергетика, 2009
The paper considers a problem pertaining to better regulation of the superheated vapour tem- perature. This improvement can be achieved while determining dynamic adjustment parameters of automatic regulation systems (ARS) due to reduction of error at ...

Complexity of Nondeterministic Graph Parameter Testing

, 2014
We study the sample complexity of nondeterministically testable graph parameters and improve existing bounds on it by several orders of magnitude. The technique used would be also of independent interest. We also discuss the special case of weak nondeterministic testing for uniform hypergraphs of arbitrary order.

Dualizing complexes and systems of parameters

Journal of Algebra, 1979
In [4] and [5] M. Hochster introduced the notion of amiability for a system of parameters in a local noetherian ring (see also the definition in 3). The existence of amiable systems of parameters is the key step for Hochster’s construction of big Cohen-Macaulay modules for rings with prime characteristic. M.
