Sound waves create whirlpools to round up tiny signs of disease
Sound waves create whirlpools tiny signs of disease
2017/2/16
Mechanical engineers at Duke University have demonstrated a tiny whirlpool that can concentrate nanoparticles using nothing but sound. The innovation could gather proteins and other biological structu...

Multiple Sources and Forms of Nitrogen Sustain Year-Round Kelp Growth on the Inner Continental Shelf of the Santa Barbara Channel
Nitrogen Sustain Year-Round Kelp Growth Santa Barbara Channel
2015/7/16
Forests of the giant kelp Macrocystis pyrifera found on coastal rocky reefs lack the large reservoirs for nutrient storage found in many terrestrial environments. Supporting their high year-round grow...

Round handles, logarithmic transforms, and smooth 4-manifolds
Round handles logarithmic transforms smooth 4-manifolds
2010/11/29
Round handles are aliated with smooth 4-manifolds in two major ways: 5-dimensional round handles appear extensively as the building blocks in cobordisms between 4-manifolds, whereas 4-dimensional rou...
Observations of Internal Kelvin Waves Trapped Round Bermuda
Internal Kelvin Waves Trapped Round Bermuda
2009/2/18
Observations of the vertical and horizontal structure of motions near Bermuda have been made with two long-term moored arrays, one relatively far from and the other close to the island. Although not c...
摘要
科学的发展孕育着突破，表遗传学研究推动着新一轮的遗传学的发展。表遗传学是研究没有DNA序列变化的、可遗传的表达改变。表遗传学不仅对医学和农业有重要的实践意义，而且还提供了理解遗传和进化的新观点。研究表明，人类基因组含有两类遗传信息，遗传学信息提供了合成生命所必需蛋白质的模板，而表遗传学信息提供了何时、何地和怎样地应用遗传学信息的指令；遗传学和表遗传学的关系有如“阴阳”，它们既相区别又协同参...
