Mixed-species plantations generally exhibit higher ecosystem?multifunctionality?than monospecific plantations. However, it is unclear how tree species functional composition influences species mixture...
In this talk, we shall use fill-in to give a new description of the positive mass theorem. By using this, we shall show that PMT on AH manifolds implies PMT on AF manifolds. This talk is based on the ...
We single out a notion of staticity which applies to any domain in hyperbolic space whose boundary is a non-compact totally umbilical hypersurface. For (time-symmetric) initial data sets modeled at in...
We will construct some new examples of steady gradient Ricci solitons with positive curvature operator. Moreover, for any 3D steady gradient Ricci soliton with positive curvature, if it is asymptotic ...
2020年12月21日,国际著名学术期刊《New Phytologist》(IF2020=10.152)在线发表了南京农业大学农学院许冬清教授和北京大学现代农学院邓兴旺院士合作完成的题为“A missense mutation in WRKY32 converts its function from a positive regulator to a repressor of photomorph...
Sign language gloves, intended to help people with visual disabilities, turn fingerspelling into text on a smartphone or computer. But fingerspelling makes up only a small part of the American Sign La...
本研究基于全基因组分析,在雷蒙德氏棉、亚洲棉、海岛棉和陆地棉基因组中分别鉴定得到16、16、31和29个NF-YA基因。通过进化树分析将NF-YA基因分为4个亚组。结构分析表明NF-YA基因在棉属进化过程中相对保守。荧光定量显示GhNF-YAs可能通过ABA和 MeJA的调控通路响应盐和干旱。VIGS沉默GhNF-YA10和GhNF-YA23的表达,能显著降低棉花对盐的抗性,表明这两个基...
延安大学翻译理论与实践课件Chapter 8 Positive vs. Negative Expressions (Affirmation vs. Negation)。
The ability to identify emotional arousal in heterospecific vocalizations may facilitate behaviors that increase survival opportunities. Crucially, this ability may orient inter-species interactions, ...
Dietary adequacy, as distinct from weight loss, has not been examined thoroughly in a diverse cohort of HIVinfected individuals.
This is the first report in the literature concerning penile hypoplasia and rudimentary prepuce in a 78,XY; SRY-positive male that received a successful surgical treatment. A six-month-old male mixed-...
In 1849, Dirichlet[5] proved that the probability that two positive integers are relatively prime is 1/zeta(2). Later, it was generalized into the case that positive integers has no nontrivial kth pow...
Background: Undernutrition is a common complication of disease and a major determinant of hospital stay outcome. Dutch hospitals are required to screen for undernutrition on the first day of admission...
Demographic changes during the last decades constitute a challenge for ensuring better and not just longer lives for ageing individuals. Active or positive ageing policy sets this as a goal and encour...
