The objectives of this study were to understand the rainfall characteristics of thewind-water erosion crisscross region on the northern Loess Plateau, China, to provide basisfor the studies on mitigation of soil erosion, estimation on surface water resources andlocal hydrological circle, etc. The Liudaogou Catchment with representative climatic andhydrologic conditions of wind-water erosion cri...

     Investigation of drought event has a great importance in the natural resources and water resources management and planning. In this research, the effect of the climate change on drought characteristics in Khoy station was investigated using the HadCM3 model under B2 scenario. The statistical downscaling was executed using SDSM 4.2.9 and observed daily precipitation, observed predictors and...

Background Neuroblastoma is the third most common malignancy in children with a very heterogeneous feature. In this study, the epidemiological and clinical characteristics of children with neuroblastoma treated in a referral oncology hospital in Shiraz, Southern Iran, were investigated. Material and method In this historical cohort study, the medical files of 36 children under 18 years old ...

We discuss recently reported observations of energetic neutral hydrogen atoms (ENAs) from an X9 solar flare/coronal mass ejection event on 5 December 2006, located at E79. The observations were made by the Low Energy Telescopes (LETs) on STEREO A and B. Prior to the arrival of the main solar energetic particle (SEP) event at Earth, both LETs observed a sudden burst of 1.6 to 15 MeV energetic ne...

On July 19 th , 2006 strong near-surface warm moisture convergence over western Iowa to the southwest of an intensifying warm front boosted temperatures above 90F with dewpoints as high as 85F in some locations. Meanwhile, a very dry, generally well-mixed air mass was in place aloft. The combination of these two ingredients resulted in extreme levels of instability that, coupled with a nearly i...

This paper presents a system that incorporates low-level object tracking and high-level event inference to solve the video event recognition problem. First, the tracking module combines the results of block tracking and human tracking to provide the trajectory as well as the basic type (human or non-human) of each detected object. The trajectories are then mapped to 3D world coordinates, given ...
