Study Finds Variation Within Species Is A Critical Aspect Of Biodiversity（图）
Variation Within Species Critical Aspect Biodiversity
2017/12/19
Concerns about biodiversity tend to focus on the loss of species from ecosystems, but a new study suggests that the loss of variation within species can also have important ecological consequences.Man...
Signature of Large Aspect Ratio Roll Vortices in Synthetic Aperture Radar Images of Tropical Cyclones
Large Aspect Ratio Roll Vortices Synthetic Aperture Radar Images Tropical Cyclones
2015/7/16
Synthetic aperture radar images of tropical cyclones have been processed into high-resolution surface wind vector fields. Examination of the surface wind divergence and wind stress curl show that wind...
Seasonal changes in the soil hydrological and erosive response depending on aspect, vegetation type and soil water repellency in different Mediterranean microenvironments
soil hydrological erosive response
2015/1/5
Mediterranean areas are characterized by a strong spatial variability that makes the soil hydrological response highly complex. Moreover, Mediterranean climate has marked seasons that provoke dramat...
Energy gaps in graphene nano-constrictions with different aspect ratios
Energy gaps graphene nano-constrictions different aspect ratios
2010/11/19
We present electron transport measurements on lithographically defined and etched graphene
nano-constrictions with different aspect ratios, including different length (l) and width (w). A roughly len...
Equidistribution of cusp forms in the level aspect
Equidistribution cusp forms level aspect
2010/11/11
Let f traverse a sequence of classical holomorphic newforms of fixed weight and increasing squarefree level q tending to infinity. We prove that the pushforward of the mass of f to the modular curve o...
Flow-type failures in fine-grained soils:an important aspect in landslide hazard analysis
Flow-type failures fine-grained soils important aspect landslide hazard analysis
2009/12/8
Forecasting the possibility of flow-type failures within a slow-moving landslide mass is rarely taken into account in quantitative hazard assessments. Therefore, this paper focuses on the potential tr...

Aspect sensitivity of VHF echoes from field aligned irregularities in meteor trails and thin ionization layers
VHF echoes meteor trails thin ionization layers
2009/2/25
The aspect sensitivity of VHF echoes from field aligned irregularities (FAI) within meteor trails and thin ionization layers is studied using numerical models. Although the maximum power is obtained w...
Dependence of radar signal strength on frequency and aspect angle of nonspecular meteor trails
radar signal strength frequency and aspect angle
2017/3/22
When a meteoroid penetrates Earth’s atmosphere, it forms a high-density ionized
plasma column immersed in the ionosphere between approximately 70 and 140 km
altitude. High-power, large-aperture (HPL...
Multiscale Domain Decomposition Methods for Elliptic Problems with High Aspect Ratios
multiscale elliptic problems domain decomposition
2007/12/11
In this paper we study some nonoverlapping domain decomposition methods for solving a class of elliptic problems arising from composite materials and flows in porous media which contain many spatial s...

Siliceous sponges as a silicon sink: An overlooked aspect of the benthopelagic coupling in the marine silicon cycle
Siliceous sponges silicon sink bathypelagic coupling marine silicon cycle
2014/5/9
Our current understanding of the silicon (Si) cycle in the ocean assumes that diatoms dominate not only the uptake of silicic acid, but also the production and recycling of biogenic silica (BSi), and ...
