Value of clinical, ultrasonographic and MRI signs as diagnostic differentiators of non-benign lipomatous tumours

Karishma Khan, Elayne Azzopardi, Liberato Camilleri, Ernest A. Azzopardi, Thomas H. Bragg
2020 Scientific Reports  
Receiver operating characteristic (ROC) analysis, odds ratios and binary logistic regression analysis was performed double-blind.  ...  When each sign is considered independently, (ROC analysis, followed by binary logistic regression) only Ultrasound depth is a significant predictor (p = 0.044) of a histologically non-benign lipoma.  ...  Our study shows that the classical "red-flag" signs 5 that are associated with malignant change are of limited value in the differentiation of lipomatous tumours.  ...

Finally, the value of each power is combined either by adding the value of the signs together (additive systems), or by multiplying, before the addition, the value of each sign by a power of the base depending  ...  Secondly, each power of the base can be expressed via signs whose value is to be added, as in the roman system, through one unique sign, as in the Western system, or through a combination of two signs,  ... 

Investigating early warning signs of oscillatory instability in simulated phasor measurements [article]

Goodarz Ghanavati, Paul D. H. Hines, Taras I. Lakoba
2013 arXiv   pre-print
Increasing variance in data from a dynamical system is a common sign of a phenomenon known as critical slowing down (CSD).  ...  This property can potentially be used as a method for monitoring oscillatory stability in power grid using high-resolution phasor measurements.  ...  We simulated this system using the power system analysis toolbox (PSAT) [23] . Here, we assume that the load power varies stochastically, with normally distributed fluctuations.  ...
