Abstract Background Gram-negative bacteria use periplasmic-binding proteins (bPBP) to transport nutrients through the periplasm.Despite immense diversity within the recognized substrates, all members of the family share a common fold that includes two domains that are separated by a conserved hinge.The hinge allows the protein to cycle between open
The present study was intended to improve the chemical properties of a saline-sodic soil using the individual application of alfalfa residue and two biochars produced from sugarcane bagasse and walnut shell, at the weighting ratio of 5%; their concomitant application with gypsum, aluminum sulfate and the mixture of these two chemical amendments was
As a self-supervised learning paradigm, contrastive learning has been widely used to pre-train a powerful encoder as Egg Cups an effective feature extractor for various downstream tasks.This process requires numerous unlabeled training data and computational resources, which makes the pre-trained encoder become the valuable intellectual property of
In the US, agriculture rapidly expanded beginning in the 1850s, influenced by homesteader policies and new technologies.With increased production also came widespread land-use/land-cover change.We analyze historical agricultural policies and associated land and water use trajectories with a focus on the Southern Great Plains (SGPs).Rapid changes in
