Background:The Functional Movement Screen(FMS^(TM)) has become increasingly popular for identifying functional limitations in basic functional *** exploratory and descriptive study was undertaken to confirm feasibility of performing the FMS^(TM) in older active adults,assess prevalence of asymmetries and to evaluate the relationship between functional movement ability,age,physical activity levels and body mass index(BMI).Methods:This is an observational study;97 men(n = 53) and women(n = 44) between the ages of 52 and 83 *** was computed and self-reported physical activity levels were *** were grouped by age(5-year intervals),BMI(normal,over-weight,and obese)and *** participant's performance on the FMS^(TM) was digitally recorded for later ***:The youngest age group(50–54 years) scored highest in all seven tests and the oldest age group(75+) scored lowest in most of the tests compared to all other age *** subjects in the 'normal weight' group performed no different than those who were in the 'overweight' group;both groups performed better than the 'obese' *** the 97 participants 54 had at least one *** pairwise correlations between the total FMS^(TM) score and age(r =-0.531),BMI(r =-0.270),and the measure of activity level(r = 0.287) were significant(p < 0.01 for all).Conclusion:FMS^(TM) scores decline with increased BMI,increased age,and decreased activity *** screen identifies range of motion-and strength-related *** FMS^(TM) can be used to assess functional limitations and *** research should evaluate if a higher total FMS^(TM) score is related to fewer falls or injuries in the older population.

以鼓山－魁岐、青田和普陀山－桃花岛三个典型岩体为例，系统研究了浙闽沿海Ｉ型－Ａ型复合花岗岩体的地质和地球化学特征。研究结果表明：复合岩体中Ｉ型与Ａ型花岗岩在主量、微量和稀土元素特征上均存在明显变异。总体而言，Ａ型花岗岩较之Ｉ型花岗岩富硅、富碱、贫钙、镁、铝，并具偏高的Ｒｂ／Ｓｒ、Ｒｂ／Ｂａ、Ｇａ／Ａｌ和偏低的ＬＲＥＥ／ＨＲＥＥ比值及显著的铕负异常。两类花岗岩的Ｎｄ、Ｓｒ同位素组成均具有壳幔混熔岩浆的特点，但仍存在一定的变异。上述变异既有岩浆分异演化的影响，又有幔源岩浆卷入的贡献，在不同的复合岩体中起主导作用的因素各不相同。通过对岩石产出动力地质背景的全面分析，结合本区不同复合岩体中二类花岗岩具不同地球化学变异特点的地质事实，提出浙闽沿海Ｉ型－Ａ型复合花岗岩是区域构造应力、断裂构造。

Four-dimensional (4D) printing is an emerging and highly innovative additive manufacturing process by which to fabricate pre-designed,self-assembly structures with the ability to transform over ***,one of the critical challenges of 4D printing is the lack of advanced 4D printing systems that not only meet all the essential requirements of shape change but also possess smart,dynamic capabilities to spatiotemporally and instantly control the shape-transformation ***,we present a facile 4D printing platform which incorporates nanomaterials into the conventional stimuli-responsive polymer,allowing the 4D printed object to achieve a dynamic and remote controlled,on-time and position shape transformation.A proof-of-concept 4D printed brain model was created using near-infrared light (NIR) responsive nanocomposite to evaluate the capacity for controllable 4D transformation,and the feasibility of photothermal stimulation for modulating neural stem cell *** novel 4D printing strategy can not only be used to create dynamic 3D patterned biological structures that can spatiotemporally control their shapes or behaviors of transformation under a human benign stimulus (NIR),but can also provide a potential method for building complex self-morphing objects for widespread applications.
