Effects of Straw Return Mode on Soil Aggregates and Associated Carbon in the North China Plain

open access: yesAgronomy, 2020
Crop straw is widely used to manage soil organic carbon (SOC) sequestration as an environmentally friendly practice in the North China Plain. However, little is known about the effects of straw returning modes on SOC sequestration in this region. Thus, a

Effect of slope shape on soil aggregate stability of slope farmland in black soil region

open access: yesFrontiers in Environmental Science, 2023
Slope erosion in the black soil region of Northeast China is complex and specific. In order to effectively control soil erosion and protect scarce black soil resources, it is necessary to reveal the law of soil erosion and the influence of basic units of

Carcinomas and Carcinoid Tumors of the Lungs and Bronchi in Children and Adolescents: The EXPeRT Recommendations

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Primary lung carcinomas and bronchial carcinoid tumors (BC) are very rare malignancies in childhood. While typical BC and mucoepidermoid carcinomas are mostly low‐grade, localized tumors with a more favorable prognosis than in adults, necessitating avoidance of overtreatment, adenocarcinomas of the lung are often diagnosed at advanced disease ...

GED‐CRN Breaks the Data Barrier: High‐Fidelity Electron Density Prediction Using Only 19 Training Molecules

open access: yesAggregate
We present GED‐CRN, a 3D convolutional residual network that achieves quantum‐chemical accuracy (MAE =7.6×10−4 bohr−3) in predicting electron densities for AIE‐active systems using only 19 training molecules—overcoming the data scarcity bottleneck via ...

Separability and Aggregation [PDF]

open access: yesEconomica, 1990
This paper examines the conditions for homothetic separability of a technology that is an aggregate of technologies of individual firms or industries. Given that the primitive (industry or firm) technologies exhibit homothetic separability, the authors establish necessary and sufficient conditions for the aggregate (sectoral) technology to also exhibit

The effects of different dusty aggregate on bituminous hot mixtures

open access: yesScience and Engineering of Composite Materials, 2014
Adhesion between aggregate and bitumen is an important parameter of the performance of bituminous hot mix pavements. Dust on the aggregate surface adversely affects bituminous hot mix pavement performance and leads to some types of deterioration, such as
