Urban riverine networks are hotspots of CO2 and CH4 emissions, due to river impoundment pollution. The river–lake connection is considered be an important way improve the ecological environment urban rivers; however, its impact on emissions from rivers regulatory mechanisms still unclear. Rivers lakes have been studied separately by lots traditional studies. In this study, we investigated conce...

Small data samples are still a critical challenge for spatial predictions. Land use regression (LUR) is widely used model predictions with observations at limited number of locations. Studies have demonstrated that LUR models can overcome the limitation exhibited by other prediction which usually require greater densities observations. However, accuracy and robustness need to be improved due li...

background: natural killer (nk) cells are the effector cells of innate immunity that respond to infection and tumor. interactions between killer cell immunoglobulin like receptors (kir) and human leukocyte antigen (hla) class i molecules regulate nk cells responses to eliminate infected and transformed cells. objective: to investigate the impact of kir genes, hla ligand genes, and kir-hla combi...

BACKGROUND HLA genes are highly polymorphic and certain alleles are frequent only in specific populations. Therefore, HLA is a unique tool for studying the genetic relation between different populations. Iranians are ethnically diverse people and one of the major ethnic groups in Iran is Lur population inhabiting along the central and southern parts of Zagros Chain Mountain. OBJECTIVE Genetic...

Abstract This paper is the first of its kind to use machine learning algorithms in conjunction with a Land-use Regression (LUR) model for predicting spatiotemporal variation CO concentrations Taiwan. We used daily concentration from 2000 2016 develop and data 2017 2018 as external verify reliability. Location temples was predictor account Asian culturally specific sources. With ability capture ...

BACKGROUND We previously reported an association between infant wheezing and residence < 100 m from stop-and-go bus and truck traffic. The use of a proximity model, however, may lead to exposure misclassification. OBJECTIVE Results obtained from a land use regression (LUR) model of exposure to truck and bus traffic are compared with those obtained with a proximity model. The estimates derived...

Satellite-based PM2.5 concentration estimation is growing as a popular solution to map the PM2.5 spatial distribution due to the insufficiency of ground-based monitoring stations. However, those applications usually suffer from the simple hypothesis that the influencing factors are linearly correlated with PM2.5 concentrations, though non-linear mechanisms indeed exist in their interactions. Ta...

Studies on the health effects of long-term average exposure to outdoor air pollution have played an important role in recent health impact assessments. Exposure assessment for epidemiological studies of long-term exposure to ambient air pollution remains a difficult challenge because of substantial small-scale spatial variation. Current approaches for assessing intra-urban air pollution contras...
