Acute cardiovascular response to isocapnic hypoxia. I. A mathematical model.
A mathematical model of the acute cardiovascular response to isocapnic hypoxia is presented. It includes a pulsating heart, the systemic and pulmonary circulation, a separate description of the vascular bed in organs with the higher metabolic need, and the local effect of O(2) on these organs. Moreover, the model also includes the action of several reflex regulatory mechanisms: the peripheral c...
متن کاملMathematical results on scale-free random graphs
Recently there has been much interest in studying large-scale real-world networks and attempting to model their properties using random graphs. Although the study of real-world networks as graphs goes back some time, recent activity perhaps started with the paper of Watts and Strogatz [55] about the ‘smallworld phenomenon’. Since then the main focus of attention has shifted to the ‘scale-free’ ...
متن کاملSimultaneous multifactor DIF analysis and detection in Item Response Theory
In this paper, two integrated Bayesian models for differential item functioning (DIF) analysis in item response theory (IRT) models are proposed and compared. The model is integrated in the sense of modelling the responses along with the DIF determination, thus allowing DIF detection and DIF explanation in a simultaneous setup. DIF occurs because item characteristics may change according to gro...

متن کاملComparing DIF methods for data with dual dependency
Background During the past few decades, there have been many studies conducted to evaluate the comparative performance of differential item functioning (DIF) methods under various conditions. These conditions, for example, include small and unbalanced sample size between groups (Woods 2009), short tests (Paek and Wilson 2011), various levels of DIF contamination (Finch 2005), multilevel data (F...
