Estimation of spatially continuous daytime particulate matter concentrations under all sky conditions through the synergistic use of satellite-based AOD and numerical models.

Satellite-derived aerosol optical depth (AOD) products are one of main predictors to estimate ground-level particulate matter (PM and PM) concentrations. Since AOD products, however, are only provided under high-quality conditions, missing values usually exist in areas such as clouds, cloud shadows, and bright surfaces. In this study, spatially continuous AOD and subsequent PM and PM concentrations were estimated over East Asia using satellite- and model-based data and auxiliary data in a Random Forest (RF) approach.

Spatial wildlife-vehicle collision models: a review of current work and its application to transportation mitigation projects.

In addition to posing a serious risk to motorist safety, vehicle collisions with wildlife are a significant threat for many species. Previous spatial modeling has concluded that wildlife-vehicle collisions (WVCs) exhibit clustering on roads, which is attributed to specific landscape and road-related factors. We reviewed twenty-four published manuscripts that used generalized linear models to statistically determine the influence that numerous explanatory predictors have on the location of WVCs.

Organization of the shrimp vitellogenin gene: evidence of multiple genes and tissue specific expression by the ovary and hepatopancreas.

Vitellogenin is the major egg yolk protein synthesized in female shrimp during gonad maturation. Although there are several reports for the cloning of vitellogenin complementary DNA (cDNA) in different crustaceans, little is known of the gene organization of this protein. This study reports the first cloning and characterization of a full-length gene encoding the vitellogenin precursor from the shrimp Metapenaeus ensis.

Models for growth, decline and regrowth of the dendrites of rat Purkinje cells induced from magnitude and link-length analysis.

This study examines Purkinje neurons of rats aged 1, 10, 18 and 28 months to investigate growth and decline in the magnitude of the dendritic tree, i.e. the number of exterior links (terminal segments) per cell.

Effects of long durations of ethanol treatment during aging on dendritic plasticity in Fischer 344 rats.

Twelve-month-old Fischer 344 rats were fed a liquid diet containing 35% ethanol until they were 18 or 24 months old. Pair-fed and chow-fed control rats were matched to each ethanol-fed rat for concurrent treatment. Cerebellar Purkinje cell networks were measured in half of the rats at the end of the ethanol treatment and in the remaining rats after a subsequent 2-month recovery period.
