This study evaluated the diagnostic performance of ultrasound elastography (USE) using carotid arterial pulsation and determined the reproducibility of USE for thyroid nodules. A total of 148 patients with 173 thyroid nodules participated. The mean elasticity contrast index (ECI) was significantly higher in malignant nodules (3.1 ± 1.5) than in benign nodules (1.7 ± 0.8) (p < 0.001). When a cut...

Engineer-Computer Interaction (ECI), is a new sub-domain of Human-Computer Interaction specifically tailored to engineers needs. ECI i) uses an information classification schema, ii) provides a modular approach to task decomposition, and iii) integrates standard engineer characteristics and working procedures into software. A software toolkit that interprets monitoring data taken from bridges w...

OBJECTIVE To examine prospectively usefulness of Early Childhood Inventory-4 (ECI-4) in identifying attention deficit-hyperactivity disorder (ADHD), oppositional defiant disorder (ODD), and conduct disorder (CD). METHOD A sample of children <6 years of age were evaluated in school settings with ECI-4 and results compared with those of Conners Rating Scales-Revised (CRS-R) 6 months later. Samp...

Hidalgo & Hausmann’s (2009) Economic Complexity Index (ECI) measures the complexity of national economies in terms of product groups. Analogously to ECI, we develop the Patent Complexity Index (PatCI) on the basis of a matrix of nations versus patent classes. Using linear algebra, the three dimensions—countries, product groups, and patent classes—can be combined into an integrated (“Triple Heli...
