The standard relational model

Coronary angiography is the gold standard for definitive diagnosis of obstructive ischemic coronary disease. However, this is an invasive, expensive test, and may have a number of complications. We aim to assess the sensitivity and specificity of different PTP stratification models follow ESC 2013 and 2019; and their use in the relation to SYNTAX score and cardiovascular risk factors.

In this work, isothermal magnetization and initial dc susceptibility of spheroidal, nearly monodisperse Mn0.7Zn0.3Fe2O4 nanoparticles (typical diameter: 20 nm) prepared by a hydrothermal route have been measured between 10 and 300 K. The high-temperature inverse magnetic susceptibility was always found to follow a linearly temperature dependence. The deviation from the standard superparamagnetic behavior is related to dipolar interaction among nanoparticles.

The literature offers many definitions of the Lean but it lacks a standard definition that would facilitate its implementation. These definitions are closely related to the specificities of the domain, sector or problem studied. The purpose of this paper is to capture the concepts of the Lean to propose a generic definition independent of the application domain.

We extend the relational model of data to consider classes as attribute values, thereby to allow eary and convernient the representation of quantified queries. Facts regarding object classes can be stored and manipulated in the same way as facts regarding object instances. Our model is upwards compatible with the standard relational model
