+The title of the three papers are:
+ - Fantastic yeasts and where to find them: the hidden diversity of dimorphic fungal pathogens
+ - An analysis of the forces required to drag sheep over various surfaces
+ - Correlation of continuous cardiac output measured by a pulmonary artery catheter versus impedance cardiography in ventilated patients
+
+The following plot shows the number of university students on one axis and the consumption of beer on the other axis. There appears to be a correlation between the two, however, the data on itself is not enough to directly relate the two data sets.
