SPATIAL AND TEMPORAL CHANGES OF AEROSOL OPTICAL DEPTH AND ITS DRIVING FACTORS BASED ON MODIS IN JIANGSU PROVINCE
AOD MODIS Temporal Change Spatial Autocorrelation Gravity Model Driving Factor
2018/5/14
Aerosol Optical Depth (AOD) is of great value for studying air mass and its changes. In this paper, we studied the spatial-temporal changes of AOD and its driving factors based on spatial autocorrelat...

Ningxia Desertification Rainfall Use Efficiency Grey Relational Analysis Driving Factors Precipitation
2018/5/17
Due to the implementation of national policy, the desertification in Ningxia has been gradually reduced, but the overall situation of desertification is still serious. Rainfall Use Efficiency(RUE) can...
Concord grape juice, cognitive function, and driving performance: a 12-wk, placebo-controlled, randomized crossover trial in mothers of preteen children
cognitive function driving flavonoids grape juice polyphenols cognition anthocyanins memory
2018/11/28
Background: Daily consumption of Concord grape juice (CGJ) over 3–4 mo has been shown to improve memory function in adults with mild cognitive impairment and reduce blood pressure in hypertensive adul...
Researchers at Case Western Reserve University have identified neurons in a cockroach’s brain that control whether the insect walks slow or fast, turns right or left or downshifts to climb.By selectiv...
A popular theory of self-organized criticality relates driven dissipative systems to systems with conservation. This theory predicts that the stationary density of the abelian sandpile model equals th...
Characterization and interaction of driving factors in karst rocky desertification: a case study from Changshun, China
In the southwest ecological problems karst rocky desertification the regional sustainable development the karst environment
2015/1/6
As the most severe ecological issue in southwest China, karst rocky desertification (KRD) has both threatened and constrained regional sustainable development. Comprehensively understanding the relati...
