Journal of Singularities, 2015
Summary: We obtain a list of all simple classes of singularities of function germs with respect to the quasi cusp equivalence relation. We discuss its connection with the singularities of Lagrangian projections in presence of a cuspidal edge. We also describe the bifurcation diagrams and caustics of simple quasi cusp singularities.

It is known that the deformation of the apparent contours of a surface under perspective projection and viewer motion enable the recovery of the geometry of the surface, for example by utilising the epipolar parametrization. These methods break down with apparent contours that are singular i.e., with cusps .

Neural Networks, 1998
The cusp bifurcation provides one of the simplest routes leading to bistability and hysteresis in neuron dynamics. We show that weakly connected networks of neurons near cusp bifurcations that satisfy a certain adaptation condition have quite interesting and complicated dynamics. First, we prove that any such network can be transformed into a canonical

The position of dayside aurora (as measured from South Pole station in 1980) is compared with the interplanetary magnetic field Bz component and to the AE index. The results are consistent with our earlier work showing a close relationship with AE and little correlation with Bz.

Cusps or no cusps—that is not the question
Journal of Oral Rehabilitation, 1979SummaryCurrent views of the significance of cusps to oral health range from an emphasis on meticulous recusping of the restored teeth to a recommendation of gradual prophylactic elimination of natural cusps by grinding.Cusps, their morphology and mutual arrangement are associated with masticatory function.
