An adaptive virtual element method for the polymeric self-consistent field theory
Computers & Mathematics with Applications, 2023 In this paper, we develop a high-order adaptive virtual element method (VEM) to simulate the self-consistent field theory (SCFT) model in arbitrary domains. The VEM is very flexible in handling general polygon elements and can treat hanging nodes as polygon vertices without additional processing.

Method for virtual optical sectioning and tomography utilizing shallow depth of field
Journal of the Optical Society of America A, 2022 A method is proposed for high-resolution, three-dimensional reconstruction of internal structures of objects from planar transmission images. The described approach can be used with any form of radiation or matter waves, in principle, provided that the depth of field is smaller than the thickness of the sample.
