BACKGROUND Although General Practitioners (GPs) are uniquely placed to identify children with emotional, social, and behavioural problems, they succeed in identifying only a small number of them. The aim of this article is to explore the strategies, methods, and tools employed by GPs in the assessment of the preschool child's emotional, mental, social, and behavioural health. We look at how GPs...

This paper examines whether the radio occultation (RO) measurements of the tropopause region are able to improve radiometric tropospheric profile retrievals, as represented by the ATOVS (Advanced TIROS Operational Vertical Sounder) temperature and humidity soundings from the NOAA16 (National Oceanic and Atmospheric Administration) satellite. First, a simulation study is presented wherein a stat...

Traveler route choice behavior is the cornerstone of numerous advanced traffic management technologies. However, few datasets of actual segment-by-segment travel routes have been collected and analyzed. This is understandable, given the difficulties faced by traditional survey methods, such as phone and mail surveys, when collecting route data. With the improved accuracy of GPS devices, it is n...

Abstract The hydrological, geological and meteorological conditions in southwestern China are relatively complex, so that the land surface deformation presents various features. Using 58 Crustal Movement Observation Network of (CMONOC) stations across four provinces Southwestern China, we adopt an improved clustering algorithm to classify 49 into 12 clusters with different similarity levels. Ou...

The use of unmanned air vehicle (UAV) images acquired by a non-metric digital camera to establish an image network is difficult in cases without accurate camera model parameters. Although an image network can be generated by continuously calculating camera model parameters during data processing as an incremental structure from motion (SfM) methods, the process is time consuming. In this study,...
