A team of university researchers has devised the first automated techniques to identify ads potentially tied to human trafficking rings and link them to public information from Bitcoin — the primary p...
Follow-up of a randomized trial on postdischarge nutrition in preterm-born children at age 8 y
preterm-born infants postdischarge nutrition follow-up growth body composition bone metabolic health
2018/11/15
Background: Early nutritional interventions may modulate health risks in preterm-born infants. Previously, we showed that preterm-born infants fed an isocaloric protein- and mineral-enriched postdisch...
The positive impact of general vitamin D food fortification policy on vitamin D status in a representative adult Finnish population: evidence from an 11-y follow-up based on standardized 25-hydroxyvitamin D data
25-hydroxyvitamin D general fortification standardization vitamin D population survey
2018/11/14
Background: A systematic vitamin D fortification of fluid milk products and fat spreads was started in 2003 in Finland to improve vitamin D status.
Ultraprocessed food consumption and risk of overweight and obesity: the University of Navarra Follow-Up (SUN) cohort study
obesity overweight ultra-processed food food-processing industry SUN cohort prospective studies
2018/12/18
Background: Ultraprocessed food consumption has increased in the past decade. Evidence suggests a positive association between ultraprocessed food consumption and the incidence of overweight and obesi...

The Algerian steppe has become for a few years the theatre of an ecological and climatic imbalance. The intense degradation for this fragile medium (stranding wind erosion, overgrazing, clearing, sali...
由于GRACE Follow-On双星系统等效于基线长为星间距离的一维水平重力梯度仪,因此本文基于GRACE Follow-On卫星重力梯度法开展了精确和快速反演下一代地球重力场的可行性论证研究. 研究结果表明:第一,基于GRACE Follow-On卫星重力梯度法(GFO-SGGM),利用卫星轨道参数(轨道高度250 km、星间距离50 km、轨道倾角89°、轨道离心率0.001)、关键载荷测量...
本文基于星间加速度法开展了插值公式、相关系数和采样间隔对GRACE Follow-On星间加速度精度影响的研究. 模拟结果表明:1)适当增加数值微分公式的插值点数可有效提高插值精度. 基于9点Newton插值公式,星间加速度的插值误差为4.401×10-13 m·s-2,分别基于7点、5点和3点插值公式,插值误差增加了1.192倍、6.912倍和274.029倍. 2)适当增大相关系数可有效降低星...
本文利用轨道扰动引力谱分析的方法有效估计了未来GRACE(Gravity Recovery And Climate Experiment)Follow-On卫星反演地球重力场的空间分辨率。基于GRACE Follow-On卫星的轨道特性,从垂直和水平两个方面计算了其在高空所受到的扰动引力谱,并根据谱特性及星载加速度计的测量噪声水平分析了该卫星能反演重力场的阶数。利用EGM96重力场模型分别计算了2...
Markov processes follow from the principle of Maximum Caliber

2011/9/14
Markov models are widely used to describe processes of stochastic dynamics. Here, we show that Markov models are a natural consequence of the dynamical principle of Maximum Caliber. First, we show tha...
