Transformation of Barchans into parabolic dunes under the influence of vegetation [PDF]

open access: yesarXiv, 2005
Barchan dunes were found to transform into parabolic dunes and vice versa when the amount of vegetation on and around them changes. This work presents the first numerical simulation of this effect. We propose a continuum model for the density of vegetation. An established sand transport model is used for simulating the evolution of the dunes.

Global Vegetation Modeling with Pre-Trained Weather Transformers [PDF]

open access: yesarXiv
Accurate vegetation models can produce further insights into the complex interaction between vegetation activity and ecosystem processes. Previous research has established that long-term trends and short-term variability of temperature and precipitation affect vegetation activity.

NF‐κB1 promotes miR‐27a‐5p upregulation in acrylamide‐induced toxicity in rats

open access: yesFood Frontiers
Acrylamide (AA) is a neurotoxic and potentially carcinogenic contaminant, usually generated during food processing. MicroRNAs are a class of noncoding small RNAs, which serve essential pathogenic roles in linking exposure to toxic contaminants with their

Measuring specialty crop grower willingness to pay for genetic modification and genetic editing

open access: yesAgribusiness, EarlyView.
Abstract In contrast to the widespread adoption of agricultural commodities modified using biotechnology, the adoption rate of bioengineered specialty crops by growers remains low. The use of bioengineered crops has been controversial since their introduction in the 1990s due to concerns about their potentially harmful effects to human health, the ...
