Restoring the top-of-atmosphere reflectance during solar eclipses: a proof of concept with the UV absorbing aerosol index measured by TROPOMI [PDF]

open access: yesAtmospheric Chemistry and Physics, 2021
During a solar eclipse the solar irradiance reaching the top of the atmosphere (TOA) is reduced in the Moon shadow. The solar irradiance is commonly measured by Earth observation satellites before the start of the solar eclipse and is not corrected for ...

Gelidocalamus zixingensis (Poaceae, Bambusoideae, Arundinarieae), a new species from southern China revealed by morphological and molecular evidence [PDF]

open access: yesPhytoKeys, 2023
The genus Gelidocalamus T. H. Wen, endemic to southern China, is a small but taxonomically problematic genus of Arundinarieae (Poaceae, Bambusoideae). During field work, a population of Gelidocalamus from Zixing, Hunan, was discovered, appearing to be ...

Flexible Trees [PDF]

open access: yesProceedings of the International Working Conference on Advanced Visual Interfaces, 2016
We introduce Flexible Trees, a sketch-based layout adjustment technique. Although numerous tree layout algorithms exist, these algorithms are usually bound to fit within standard shapes such as rectangles, circles and triangles. In order to provide the possibility of interactively customizing a tree layout, we offer a free-form sketch-based interaction

Assessing Demand and Supply Perspectives in Marine Wildlife Voluntourism: A Case of Southern Africa [PDF]

open access: yesAfrican Journal of Hospitality, Tourism and Leisure, 2022
Marine wildlife voluntourism (MVT) is an alternative form of tourism that has grown due to the desire of people to assist in conservation efforts and research. There is limited research on the demand and supply perspectives of MVT and whether these align.

Proteome profiles during early stage of somatic embryogenesis of two Eucalyptus species

open access: yesBMC Plant Biology, 2022
Background Somatic embryogenesis (SE) was recognized as an important tool for plants to propagate. However, our knowledge about the proteins involved in early SE including the callus dedifferentiation is still limited, especially in the economic woody ...

Tree compression with top trees [PDF]

open access: yesInformation and Computation, 2013
We introduce a new compression scheme for labeled trees based on top trees. Our compression scheme is the first to simultaneously take advantage of internal repeats in the tree (as opposed to the classical DAG compression that only exploits rooted subtree repeats) while also supporting fast navigational queries directly on the compressed representation.

Hash Trees Versus B-Trees [PDF]

open access: yesThe Computer Journal, 1984
Summary: The hash trees method of external hashing is known to have advantages for certain types of primary key distribution. In this paper the value of the method as a general indexing technique - for secondary keys as well as primary keys - is assessed, and comparison with the B-trees method is presented.
