Assessment of Grassland Degradation on the Tibetan Plateau Based on Multi-Source Data

open access: yesRemote Sensing, 2022
Grassland is one of the most widely distributed ecosystems on the Tibetan Plateau (TP) accounting for about 60% of the total area. The grassland degradation has spread throughout the TP, and the scope and degree are increasing. The inconsistency of multi-

Data Structures for 2D Representation of Terrain Models

open access: yesEncyclopedia
This entry gives an overview of the main data structures and approaches used for a two-dimensional representation of the terrain surface using a digital elevation model (DEM). A DEM represents the elevation of the earth surface from a set of points.

Influence of Land Use Patterns on Evapotranspiration and Its Components in a Temperate Grassland Ecosystem

open access: yesAdvances in Meteorology, 2015
To better understand variation in response of components of ecosystem evapotranspiration (ET) to grassland use differences, we selected three typical land use patterns in a temperate steppe area: grazed steppe (G), steppe with grazers excluded (GE), and ...

Coupling coordination degree spatial analysis and driving factor between socio-economic and eco-environment in northern China

open access: yesEcological Indicators, 2022
Coordinating ecological and socioeconomic development is the only way to achieve regional sustainability. In this paper, the total output value of ecosystem services was selected to evaluate the ecological environment, and socioeconomic indicators were ...

Flow aligned surfacing of curve networks [PDF]

open access: yesACM Transactions on Graphics, 2015
We propose a new approach for automatic surfacing of 3D curve networks, a long standing computer graphics problem which has garnered new attention with the emergence of sketch based modeling systems capable of producing such networks. Our approach is motivated by recent studies suggesting that artist-designed curve networks consist of descriptive ...

Evaluation of global gridded crop models (GGCMs) for the simulation of major grain crop yields in China

open access: yesHydrology Research, 2022
Multimodel ensembles are powerful tools for evaluating agricultural production. Multimodel simulation results provided by the Global Gridded Crop Model Intercomparison (GGCMI) facilitate the evaluation of the grain production situation in China.

An Empirical Method of Estimating Soil Thermal Inertia

open access: yesAdvances in Meteorology, 2015
A method of estimating soil thermal inertia (STI), which uses midday soil heat flux (Gm) and diurnal surface temperature amplitude as the inputs, is presented in the paper. Gm is achieved from an empirical relationship between net radiation (Rn) and soil

Nephrogenic Rests/Nephroblastomatosis in Patients With Unilateral Wilms Tumor Are Not Associated With an Increased Risk of Relapse: An Analysis of Patients Treated on the SIOP‐WT‐2001 Protocol in the SIOP‐UK‐CCLG and SIOP‐GPOH Studies (2001–2022)

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Introduction Nephrogenic rests (NRs) and nephroblastomatosis (NBM) are precursor lesions for development of Wilms tumor (WT). Their association with the risk of relapse has not been properly assessed, partly due to misunderstanding of their diagnostic criteria and terminology.
