On splitting the area under curves

Journal of Differential Equations, 1977
AbstractTwo area-splitting problems involving real-valued functions of a real variable are investigated. The second of these is essentially equivalent to finding all functions a ϵ C1((0, r)) with 0 < a(x) < x which satisfy the functional differential equation a′ (a(x)) = a(x)x for x ϵ (0, r). All solutions analytic at x = 0 (and many which are not) are

Factors affecting free vancomycin concentration and target attainment of free area under the concentration-time curve

Journal of Pharmaceutical Health Care and Sciences
Background It has been reported that the protein binding rate of vancomycin (VCM) varies among individual patients. So, the authors investigated relevant factors that may affect free VCM concentration and target attainment of free area under the ...

Testing the significance of crossover receiver operating characteristic curves in the presence of multiple markers

Journal of Biostatistics and Epidemiology, 2017
Background & Aim: In multivariate receiver operating characteristic (MROC) curve analysis, comparing two tests is usually done by means of area under the curve (AUC’s) and sensitivities.

Area Under the Curve

Jay tightened the tattered canvas straps of his heavy pack and gazed at the jagged ridgeline that violently bisected the light dawn sky. It was a difficult climb, a cruel spine of granite that had bested better, stronger trekkers than his. But today Jay wasn’t seeing the mountain as one, insurmountable challenge.

Towards non-invasive diagnosis of glioblastoma: identifying metabolic biomarkers in liquid biopsies using a ROC-based approach

Discover Oncology
For over seven decades, the World Health Organization (WHO) has classified central nervous system tumors primarily based on histological criteria. While recent updates have incorporated molecular genetics and histochemistry, this approach still overlooks

Development of a prediction method for severe pancreatitis using a nomogram

Frontiers in Medicine
IntroductionThe identification of severe acute pancreatitis (SAP) is paramount for effective patient management, but the gold standard for diagnosing SAP requires over 48 h of organ failure, which may delay timely treatment.
