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

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

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

Plasmid-based one-pot saturation mutagenesis [PDF]
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 ...
