In practical applications, how to achieve a perfect balance between high accuracy and computational efficiency can be the main challenge for simultaneous localization and mapping (SLAM).To solve this challenge, we propose SD-VIS, a novel fast and accurate semi-direct visual-inertial SLAM framework, which can estimate camera motion and structure of
A hazard quotient (HQ) for a single chemical and the hazard index (HI) for a mixture of chemicals were first bushranger awning described as approaches for risk characterisation by the EPA.HQ is defined as the ratio of exposure to an appropriate reference dose such as the ADI.HI is the sum of the HQs of the chemicals in a mixture.HQ and HI have been
Babylonia areolata is an aquatic mollusk in the genus of the gastropod bushranger awning family Buccinidae.Genetic variations were observed in the 542 base pairs of the sequences from its cytochrome oxidase subunit I (COI) gene of mtDNA.COI alignments showed that there were two monophyletic clades on the phylogenetic tree, referred as B.areolata.Th
The terrestrial green alga Chromochloris zofingiensis is an emerging model species with potential applications including production of triacylglycerol or astaxanthin.How C.zofingiensis interacts with the diverse substrates during trophic transitions is unknown.To characterize its substrate utilization and secretion dynamics, we cultivated the alga
