Effects of soil and climatic factors on the potential distribution of Castanopsis eyrei in China [PDF]

open access: yesFrontiers in Plant Science
The geographical distributions of plant species are being actively reshaped by climate change. Castanopsis eyrei, a cornerstone species of subtropical evergreen broad-leaved forests in China, plays a critical role in community assembly and carbon ...

Lyapunov‐based saturated continuous twisting algorithm [PDF]

open access: yesInternational Journal of Robust and Nonlinear Control, 2020
AbstractIn this article, a second‐order system, which is affected by disturbances and uncertainties, with a saturating actuator is considered. A novel robust feedback control law is designed based on the sliding mode technique. The twisting and the continuous twisting algorithms are incorporated into the design, which is based on level curves of a ...

Forms of lime application and use of phosphogypsum in low acid soil in southern Brazil: soybean-wheat yield and soil chemical properties

open access: yesRevista Brasileira de Ciência do Solo, 2021
Brazil is currently the leading country in no-till (NT) farming, particularly on Ferralsols (Latossolos), the most abundant soil type. These soils are characterized by subsurface acidity that cannot be effectively corrected by surface application of ...

Oxygen Saturation Imaging Using LED-Based Photoacoustic System [PDF]

open access: yesSensors, 2021
Oxygen saturation imaging has potential in several preclinical and clinical applications. Dual-wavelength LED array-based photoacoustic oxygen saturation imaging can be an affordable solution in this case. For the translation of this technology, there is a need to improve its accuracy and validate it against ground truth methods.

Afforestation With Different Tree Species Causes a Divergent Evolution of Soil Profiles and Properties

open access: yesFrontiers in Forests and Global Change, 2021
Land-use change and specifically a change in the type of vegetation cover affects soil morphology, chemistry, biology, and nutrient regimes. Numerous studies have documented that in land-use conversions from agricultural land to forest, or from ...

Seedlings of Cedrela fissilis Vell. respond to single superphosphate application, but not to liming [PDF]

open access: yesRevista Ceres, 2023
Cedro-rosa (Cedrela fissilis) is native to Brazil with great potential for seedling production. However, soil correction is necessary to improve its performance, due to the edaphoclimatic conditions in Brazil, where soils have a high weathering degree ...

The Influence of Tree Species on the Recovery of Forest Soils from Acidification in Lower Saxony, Germany

open access: yesSoil Systems, 2022
Atmospheric acid deposition has increased sharply since the beginning of industrialization but has decreased considerably since the 1980s owing to clean-air policies.

Plasmid-based one-pot saturation mutagenesis [PDF]

open access: yesNature Methods, 2016
Deep mutational scanning is a foundational tool for addressing the functional consequences of large numbers of mutants, but a more efficient and accessible method for construction of user-defined mutagenesis libraries is needed. Here we present nicking mutagenesis, a robust, single-day, one-pot saturation mutagenesis method performed on routinely ...
