Climate Change and Topography Drive the Expansion of <i>Betula ermanii</i> in the Alpine Treeline Ecotone of the Changbai Mountain. [PDF]
Ecol EvolOver the past 20 years, the expansion rate of Betula ermanii in the alpine ecotone of Changbai Mountain varied with mountain aspects. We found that interactions between climate and topographic factors played a more significant role in B. ermanii's expansion than any single dominant factor.

Sparse regularization method combining SVA for feature enhancement of SAR images
Electronics Letters, Volume 58, Issue 15, Page 591-593, July 2022., 2022 Abstract Sparse signal processing has been widely used in synthetic aperture radar imaging and feature enhancement of images in the recent decade. Sparse regularization ℓ1 can reduce the imaging noise level and suppress sidelobes. However, the suppression of sidelobes by sparse regularization often pays the price of losing information of weak targets ...
