Moving object environments are characterized by large numbers of moving objects and numerous concurrent continuous queries over these objects. Efficient evaluation of these queries in response to the movement of the objects is critical for supporting acceptable response times. In such environments the traditional approach of building an index on the objects (data) suffers from the need for freq...

Efficient evaluation of 12 these queries in response to the movement of the objects is 13 critical for supporting acceptable response times. In such 14 environments the traditional approach of building an index 15 on the objects (data) suffers from...

Drought is a natural phenomenon that causes lot of damages annually in various sectors, including agriculture and resources. The aim this study to evaluate the influence meteorological drought index on vegetation index. For purpose, standard precipitation (SPI) as calculated using data 28 stations located area Lorestane province, Iran, during years 1987–2017. Then, condition (VCI) computed norm...

Patients with vascular cognitive impairment (VCI) commonly exhibit deficits in processing speed. This has been attributed to a disruption of frontal-subcortical neuronal circuits by ischemic lesions, but the exact mechanisms and underlying anatomical structures are poorly understood. We set out to identify a strategic brain network for processing speed by applying graph-based data-mining techni...

BACKGROUND Vascular cognitive impairment (VCI), compared to vascular dementia (VD), has a broader definition and highlights the effect of vascular disease in dementia, and stroke seems play an important role in the development of VCI. However, not all patients with brain infarcts suffer from VCI; unique risk factors appear to cause such progression. This study aimed to find potential risk facto...

Various drought monitoring models have been developed from different perspectives, as drought is impacted by various factors (precipitation, evaporation, runoff) and usually reflected in various aspects (vegetation condition, temperature). Cloud not only plays an important role in the earth's energy balance and climate change, but also directly impacts the regional precipitation and evaporation...

BACKGROUND AND PURPOSE Stroke is the major cause of vascular behavior and cognitive disorders worldwide. In developing countries, there is a dearth of information regarding the public health magnitude of stroke. The aim of the Fogarty-Mexico cohort was to assess the prevalence of vascular behavioral and cognitive disorders, ranging from mild vascular cognitive impairment (VCI) to vascular demen...

Vascular Cognitive Impairment (VCI) includes vascular dementia, mixed dementia (Alzheimer’s disease [AD] with cerebrovascular disease), and vascular mild cognitive impairment, and it is a common cause of cognitive dysfunction1. Some may even contend that it is the most common cause of cognitive impairment. This is based principally on clinicopathological data showing that most aged individuals ...
