Acta Physica Polonica A, 2011 p–n GaN diodes were studied by means of conventional deep level transient spectroscopy and Laplace transform deep-level spectroscopy methods within the temperature range of 77–350 K. Deep level transient signal spectra revealed the presence of a majority and minority trap of indistinguishable signatures.

Deep Stacked Hierarchical Multi-Patch Network for Image Deblurring [PDF]
Computer Vision and Pattern Recognition, 2019 Despite deep end-to-end learning methods have shown their superiority in removing non-uniform motion blur, there still exist major challenges with the current multi-scale and scale-recurrent models: 1) Deconvolution/upsampling operations in the coarse-to-

DeepEMhancer: a deep learning solution for cryo-EM volume post-processing
Communications Biology, 2020 Cryo-EM maps are valuable sources of information for protein structure modeling. However, due to the loss of contrast at high frequencies, they generally need to be post-processed to improve their interpretability.
