Extensions on Low-Complexity DCT Approximations for Larger Blocklengths Based on Minimal Angle Similarity
The discrete cosine transform (DCT) is a central tool for image and video coding because it can be related to the Karhunen-Loéve transform (KLT), which is the optimal transform in terms of retained transform c...

Determining ecosystem functioning in Brazilian biomes through foliar carbon and nitrogen concentrations and stable isotope ratios
By analyzing 6,480 tree leaf samples from 57 sites within Brazilian biomes, we considered whether vegetation types in terrestrial ecosystems reflect biogeochemical diversity and whether they fit into a leaf ec...

Open AccessChiral magnetic chemical bonds in molecular states of impurities in Weyl semimetals
We demonstrate that chirality of the electron scattering in Weyl semimetals leads to the formation of magnetic chemical bonds for molecular states of a pair of impurities. The effect is associated with the pre...

Endophytic Actinobacteria for Sustainable Agricultural Applications
Endophytic actinobacteria have the capacity to establish intimate associations with plants and colonize their inner tissues without causing apparent disease symptoms. They can protect plants by producing bioac...

Curative embolization of pediatric intracranial arteriovenous malformations using Onyx: the role of new embolization techniques on patient outcomes
Intracranial arteriovenous malformations (AVMs) are the most frequent cause of hemorrhagic strokes in the pediatric population. The study aim was to retrospectively assess the safety and efficacy of Onyx embol...

Death from drought in tropical forests is triggered by hydraulics not carbon starvation
It has been suggested that carbon starvation, owing to reduced availability of non-structural carbohydrates (NSCs), is an important contributor to tree mortality during drought in tropical rainforests; however...

Current Neurogenic and Neuroprotective Strategies to Prevent and Treat Neurodegenerative and Neuropsychiatric Disorders
The adult central nervous system is commonly known to have a very limited regenerative capacity. The presence of functional stem cells in the brain can therefore be seen as a paradox, since in other organs the...

Association between two visual criteria in assessing non-cavitated caries lesion activity on occlusal surfaces of permanent molars
This study aimed to evaluate the association between two visual criteria in assessing non-cavitated caries lesion activity on occlusal surfaces of permanent molars.

Convergence of a specialized root trait in plants from nutrient-impoverished soils: phosphorus-acquisition strategy in a nonmycorrhizal cactus
In old, phosphorus (P)-impoverished habitats, root specializations such as cluster roots efficiently mobilize and acquire P by releasing large amounts of carboxylates in the rhizosphere. These specialized root...

Two new species of Habranthus (Amaryllidaceae) from the Espinhaço Range, Brazil
During floristic work on Espinhaço Range-Brazil, we recognised five Habranthus species, plus two new species, described and illustrated here: Habranthus botumirimensis R. S. Oliveira is similar to H. datensis Rav...
