Higher dietary flavonoid intakes are associated with lower objectively measured body composition in women: evidence from discordant monozygotic twins
body composition diet fat distribution flavonoids twins
2018/11/13
Background: Although dietary flavonoid intake has been associated with less weight gain, there are limited data on its impact on fat mass, and to our knowledge, the contribution of genetic factors to ...
Genetic and environmental effects on body mass index from infancy to the onset of adulthood: an individual-based pooled analysis of 45 twin cohorts participating in the COllaborative project of Development of Anthropometrical measures in Twins (CODATwins) study

利用差分体像素CT由TWINS卫星ENA成像反演暴时环电流离子三维分布
TWINS卫星 环电流 磁暴
2015/7/27
本文将体像素CT方法应用于TWINS卫星高能中性原子立体成像数据,重建环电流离子通量强度三维分布.为了克服卫星ENA成像可能存在的仪器偏差造成反演误差增大甚至迭代发散无解的问题,发展了差分ENA体像素CT反演方法.采用环电流离子分布理论模型和实际卫星观测几何构形进行模拟检验,证明了该方法的可靠性和优越性.利用此方法分析2012年7月15日磁暴(min Dst=-133 nT)主相期间TWINS 两...
Einstein's Clocks and Langevin's Twins
Einstein's Clocks Langevin's Twins History and Philosophy of Physics
2012/5/28
In 1905 Einstein presented the Clock Paradox and in 1911 Paul Langevin expanded Einstein's result to human observers, the "Twin Paradox." I will explain the crucial difference between Einstein and Lan...
Detailed Abundances of the Solar Twins 16 Cygni A and B: Constraining Planet Formation Models
Detailed Abundances Solar Twins Constraining Planet Formation Models
2011/10/10
Results of a detailed abundance analysis of the solar twins 16 Cyg A and 16 Cyg B based on high-resolution, high signal-to-noise ratio echelle spectroscopy are presented. 16 Cyg B is known to host a g...
Solar twins in M67 : Evolutionary status and lithium abundance
Stars fundamental parameters – Stars abundances – Stars evolution – Stars interiors – Stars solar-type
2010/11/11
Aims. We determine the age and mass of the three best solar twin candidates in open cluster M67 through lithium evolutionary models.Methods. We computed a grid of evolutionary models with non-standard...
Astronomers could be on the cusp of detecting gravitational waves after four decades of trying, according to a team of Polish astrophysicists. They say that if current gravitational-wave detectors are...
The TWINS-LAD mission：Observations of terrestrial Lyman-α fluxes
terrestrial Lyman-α fluxes line-of-sight Two Wide-angle Imaging Neutral-atom Spectrometers
2009/5/27
The TWINS project (Two Wide-angle Imaging Neutral-atom Spectrometers) is mainly devoted to measure high energy neutral atoms (ENAs) originating via charge exchange of protons with geocoronal hydrogen ...
Needle twins and right-angled twins in minerals: Comparison between experiment and theory
Needle twins right-angled twins Comparison theory
2012/4/1
Transformation twinning in minerals forms isolated twin walls, intersecting twin walls with corner junctions, and wedge-shaped twins as elements of hierarchical patterns. When cut perpendicular to the...
