Characterization and Comparison of Convergence Among Cephalotus follicularis Pitcher Plant-Associated Communities With Those of Nepenthes and Sarracenia Found Worldwide

open access: yesFrontiers in Plant Science, 2022
The Albany pitcher plant, Cephalotus follicularis, has evolved cup-shaped leaves and a carnivorous habit completely independently from other lineages of pitcher plants.

Recent advances in optical imaging through deep tissue: imaging probes and techniques

open access: yesBiomaterials Research, 2022
Optical imaging has been essential for scientific observations to date, however its biomedical applications has been restricted due to its poor penetration through tissues. In living tissue, signal attenuation and limited imaging depth caused by the wave

Integrate Influence of Regions and Friends for Next POI Recommendation

open access: yesJisuanji kexue yu tansuo, 2021
With the increasing popularity of mobile devices, a large amount of user check-in point of interests (POIs) data have been accumulated. The information of user check-in makes the recommendation of the next POI become a hot issue in recent years.

Dispersion of Surface Drifters in the Tropical Atlantic

open access: yesFrontiers in Marine Science, 2021
The Tropical Atlantic Ocean has recently been the source of enormous amounts of floating Sargassum macroalgae that have started to inundate shorelines in the Caribbean, the western coast of Africa and northern Brazil.

Low-Order Scaling Quasiparticle Self-Consistent GW for Molecules

open access: yesFrontiers in Chemistry, 2021
Low-order scaling GW implementations for molecules are usually restricted to approximations with diagonal self-energy. Here, we present an all-electron implementation of quasiparticle self-consistent GW for molecular systems.

Extended convergence of two-step iterative methods for solving equations with applications

open access: yesJournal of Numerical Analysis and Approximation Theory
The convergence of two-step iterative methods of third and fourth order of convergence are studied under weaker hypotheses than in earlier works using our new idea of the restricted convergence region.

Biogeographical patterns and speciation of the genus Pinguicula (Lentibulariaceae) inferred by phylogenetic analyses.

open access: yesPLoS ONE, 2021
Earlier phylogenetic studies in the genus Pinguicua (Lentibulariaceae) suggested that the species within a geographical region was rather monophyletic, although the sampling was limited or was restricted to specific regions. Those results conflicted with

Impact of COVID-19 lockdown on the ambient air-pollutants over the Arabian Peninsula

open access: yesFrontiers in Environmental Science, 2022
Lockdowns imposed across the world to combat the spread of the COVID-19 pandemic also reduced the anthropogenic emissions. This study investigates the changes in the anthropogenic and natural pollution levels during the lockdown over the Arabian ...

Pleistocene glacial history of the New Zealand subantarctic islands [PDF]

open access: yesClimate of the Past, 2019
The New Zealand subantarctic islands of Auckland and Campbell, situated between the subtropical front and the Antarctic Convergence in the Pacific sector of the Southern Ocean, provide valuable terrestrial records from a globally important climatic ...

Reconstructing enzyme evolution by protein engineering

open access: yesFEBS Letters, EarlyView.
Natural enzyme evolution can be retraced by protein engineering methods such as directed evolution, rational design, and ancestral sequence reconstruction. These approaches reveal how enzymes emerged from ligand‐binding scaffolds, developed varying substrate preferences, formed oligomeric complexes, adapted to environmental changes, and evolved novel ...
