Leaf water shedding: Moving away from assessments based on static contact angles, and a new device for observing dynamic droplet roll‐off behaviour

open access: yesMethods in Ecology and Evolution, 2023
Leaf wettability and drainage characteristics of different taxa are often hypothesised to have emerged as a result of evolutionary selection, perhaps to limit the duration of leaf wetness, or to direct water toward efficiently to the soil and root system,

New constructions of MDS codes with complementary duals

open access: yes, 2017
Linear complementary-dual (LCD for short) codes are linear codes that intersect with their duals trivially. LCD codes have been used in certain communication systems. It is recently found that LCD codes can be applied in cryptography. This application of
