A Novel Vegetation Index Approach Using Sentinel-2 Data and Random Forest Algorithm for Estimating Forest Stock Volume in the Helan Mountains, Ningxia, China

open access: yesRemote Sensing, 2023
Forest stock volume (FSV) is a major indicator of forest ecosystem health and it also plays an important part in understanding the worldwide carbon cycle.

Specific lid-base contacts in the 26s proteasome control the conformational switching required for substrate degradation. [PDF]

open access: yes, 2019
The 26S proteasome is essential for proteostasis and the regulation of vital processes through ATP-dependent degradation of ubiquitinated substrates. To accomplish the multi-step degradation process, the proteasomes regulatory particle, consisting of lid

Optical transmittance degradation in tapered fibers [PDF]

open access: yes, 2011
We investigated the cause of optical transmittance degradation in tapered fibers. Degradation commences immediately after fabrication and it eventually reduces the transmittance to almost zero.

Regional Farmers’ Perception and Societal Issues in Vineyards Affected by High Erosion Rates

open access: yesLand, 2021
We explore the current situation in a viticultural region in Eastern Spain from a holistic and multifaceted research approach, which allowed us to understand the biophysical conditions, economic cost, social impact, and perception of the farmers ...

Lignin‐degrading enzymes [PDF]

open access: yesThe FEBS Journal, 2015
A main goal of green biotechnology is to reduce our dependence on fossil reserves and to increase the use of renewable materials. For this, lignocellulose, which is composed of cellulose, hemicellulose and lignin, represents the most promising feedstock.

Degrading Lists

open access: yesProceedings of the 22nd International Symposium on Principles and Practice of Declarative Programming, 2020
We discuss the relationship between monads and their known generalisation, graded monads, which are especially useful for modelling computational effects equipped with a form of sequential composition. Specifically, we ask if a graded monad can be extended to a monad, and when such a degrading is in some sense canonical. Our particular examples are the

Hyperglycemia triggers HIPK2 protein degradation [PDF]

open access: yes, 2016
Homeodomain interacting protein kinase-2 (HIPK2) is an evolutionary conserved kinase that modulates several key molecular pathways to restrain tumor growth and induce p53-depending apoptotic cell-death in response to anticancer therapies. HIPK2 silencing

Characterizing degradation of palm swamp peatlands from space and on the ground: an exploratory study in the Peruvian Amazon [PDF]

open access: yes, 2017
Peru has the fourth largest area of peatlands in the Tropics. Its most representative land cover on peat is a Mauritia flexuosa dominated palm swamp (thereafter called dense PS), which has been under human pressure over decades due to the high demand for

Effect of enclosure on reproductive allocation of wheatgrass Agropyron mongolicum populations in desert steppes

open access: yesEcology and Evolution, 2019
Plants generally adopt different reproductive strategies to adapt to their environments and increase their fitness. Here, we studied the effects of enclosure cultivation on the reproductive allocation of a wheatgrass species Agropyron mongolicum in the ...
