Efficient Smoothed Concomitant Lasso Estimation for High Dimensional Regression [PDF]
, 2016 In high dimensional settings, sparse structures are crucial for efficiency, both in term of memory, computation and performance. It is customary to consider $\ell_1$ penalty to enforce sparsity in such scenarios. Sparsity enforcing methods, the Lasso being a canonical example, are popular candidates to address high dimension.

Maxwell-compensated design of asymmetric gradient waveforms for tensor-valued diffusion encoding [PDF]
Magn Reson Med 2019;82(4):1424-1437, 2019 Purpose: Asymmetric gradient waveforms are attractive for diffusion encoding due to their superior efficiency, however, the asymmetry may cause a residual gradient moment at the end of the encoding. Depending on the experiment setup, this residual moment may cause significant signal bias and image artifacts.
