Examples of strongly convex loss functions

Question

This is a reference request. Strong convexity of the loss function is often used in theoretical analyses of convex optimisation for machine learning. My question is, are there important / widely used loss functions (or cost functions) being used in machine learning in practice? I know of the logistic loss for classification, and the square loss for regression. Are there any others?

Another example is Hinge loss used in SVM.

Combination between L1 and L2 regularization (https://en.wikipedia.org/wiki/Elastic_net_regularization).
