Sheep Face Detection Based on an Improved RetinaFace Algorithm.

The accurate breeding of individual sheep has shown outstanding effectiveness in food quality tracing, prevention of fake insurance claims, etc., for which sheep identification is the key to guaranteeing its high performance. As a promising solution, sheep identification based on sheep face detection has shown potential effectiveness in recent studies.

Discovery and optimization of selective RET inhibitors via scaffold hopping.

Aberrant alterations of rearranged during transfection (RET) have been identified as actionable drivers of multiple cancers, including thyroid carcinoma and lung cancer. Currently, several approved multikinase inhibitors such as vandetanib and cabozantinib demonstrate clinical activity in patients with RET-rearranged or RET-mutant cancers. However, the observed response rates are only modest and the 'off-target' toxicities resulted from the inhibition of other kinases is also a concern.

Hotspots of reactive nitrogen loss in China: Production, consumption, spatiotemporal trend and reduction responsibility.

Effective and fair mitigation measures hinge on the identification of hotspots and tracking provenance on reactive nitrogen (Nr) loss at a high spatial resolution. We assessed the Nr loss intensity in China at 1 km spatial resolution from 1980 to 2015. The total Nr loss increased from 20.

Effect of balanced nutrient fertilizer: A case study in Pinggu District, Beijing, China.

Agriculture has played an indispensable role in the economic and social development of China. However, the inappropriate application of fertilizers in agriculture has brought about environmental pollution. Therefore, under the requirements of green development, the inevitable choice has been reducing the application amount while increasing the utilization rate of fertilizers.

2D van der Waals heterostructures of graphitic BCN as direct Z-scheme photocatalysts for overall water splitting: the role of polar π-conjugated moieties.

The application of two-dimensional (2D) graphitic carbon-based materials in photocatalysis has been limited to date, because the nature and role of π-conjugated moieties in them remain unclear. Herein we propose and study bilayer BC/CN and BC/BCN van der Waals heterostructures as direct Z-scheme photocatalysts for overall water splitting using density functional theory calculations. The roles of polar π-conjugated moieties in the formation, stacking configuration, and electronic and optical properties of bilayer van der Waals heterostructures are discussed.

A temporal-spatial analysis and future trends of ammonia emissions in China.

Excessive anthropogenic activities have led to high-level ammonia loss and volatilization, which is regarded as a key factor in Chinese haze formation. In this study, a comprehensive analysis of ammonia emission estimations is accomplished at both temporal (1980-2016) and spatial (provincial) scales using a mass-balanced model, and emission projections through 2030 are also studied in different development scenarios. The results show that the ammonia emissions increased from 4.

N-Promoted Ru/TiO single-atom catalysts for photocatalytic water splitting for hydrogen production: a density functional theory study.

We propose a universal dimer-doping strategy to improve the photocatalytic water splitting activity of Ru/TiO single-atom catalysts, in which the N atom is simultaneously doped. First-principles calculations show that the N dopants promote the substitution of Ti with Ru on the anatase TiO(101) surface by chemical bonding between Ru and N, and increase the stability of the system. Isolated Ru atoms act as active sites for the reduction of protons, and Ru-N/TiO has a hydrogen evolution activity comparable to that of Pd.

Promoting information technology for the sustainable development of the phosphate fertilizer industry: a case study of Guizhou Province, China.

The information technology revolution has brought unprecedented opportunities to the sustainable development of the traditional phosphate fertilizer industry. In this paper, the changes in characteristic indexes during this technological progress and business innovation are investigated at the industrial level and for different stakeholders using scenario simulation analysis based on system dynamics. The results show that information technology will have a significant impact on the traditional fertilizer industry.

The trends of aquacultural nitrogen budget and its environmental implications in China.

The rapid development of aquaculture has sustained aquatic food production but has also led to a host of environmental problems, ranging from eutrophication of aquatic ecosystems to global acidification. China has become the world's largest producer and consumer of aquaculture products. Nitrogen is an essential nutrient in aquaculture ecosystems, and the quantitative environmental fate and impact of nitrogen during aquaculture processes have notable environmental consequences but have received little attention.

From Production to Consumption: A Coupled Human-Environmental Nitrogen Flow Analysis in China.

Anthropogenic inputs of reactive nitrogen (Nr) provide sufficient food, energy, and industrial products to meet human demands; however, only a fraction of Nr is consumed as food and nonfood goods, and the rest is lost to the environment and negatively affects ecosystems. High-resolution studies of nitrogen flows are invaluable to increase nitrogen use efficiencies and reduce environmental emissions. In this study, a comprehensive substance flow analysis of nitrogen for China in 2014 is presented.

Biomodification of PCL Scaffolds with Matrigel, HA, and SR1 Enhances De Novo Ectopic Bone Marrow Formation Induced by rhBMP-2.

The de novo formation of ectopic bone marrow was induced using 1.2-mm-thin polycaprolactone (PCL) scaffolds biomodified with several different biomaterials. In vivo investigations of de novo bone and bone marrow formation indicated that subcutaneous implantation of PCL scaffolds coated with recombinant human bone morphogenetic protein-2 (rhBMP-2) plus Matrigel, hydroxyapatite (HA), or StemRegenin 1 (SR1) improved formation of bone and hematopoietic bone marrow as determined by microcomputed tomography, and histological and hematopoietic characterizations.

[Adjunctive therapy of xuezhikang capsule for coronary heart disease: a systematic review and meta-analysis of randomized controlled trials].

Objective: To systematically evaluate the effect and safety of Xuezhikang Capsule (XZKC) for adjuvant treatment for coronary heart disease (CHD) patients accompanied with or without dyslipidemia.

Methods: China National Knowledge Infrastructure (CNKI) Database, Chongqing VIP Database (VIP), Wanfang Data base, Cochrane Library, and Medline (PubMed) were retrieved with the deadline of August 30, 2013. Randomized controlled trials (RCT) of XZKC in treating CHD patients with or without dyslipidemia were all included.
