A New Internal Validity Index for Fuzzy
Fuzzy c-Means (FCM) is a popular clustering algorithm that can partition a set of objects into groups such that objects within a group are similar to each other and dissimilar to those in other groups.

The validity and reliability of the exposure index as a metric for estimating the radiation dose to the patient [PDF]
Introduction With the introduction of digital radiography, the feedback between image quality and over-exposure has been partly lost which in some cases has led to a steady increase in dose.

Screening for lung cancer: A systematic review of overdiagnosis and its implications
Low‐dose computed tomography (CT) screening for lung cancer may increase overdiagnosis compared to no screening, though the risk is likely low versus chest X‐ray. Our review of 8 trials (84 660 participants) shows added costs. Further research with strict adherence to modern nodule management strategies may help determine the extent to which ...

Refractive index of a transparent liquid measured with a concave mirror
This paper describes the spherical concave mirror method for measuring the index of refraction of transparent liquids. We derived the refractive index equation using Snell's law and the small-angle approximation.
