Biological filter capable of simultaneous nitrification and denitrification for Aquatic Habitat in International Space Station

Life Sciences in Space Research, 2014
The biological filter capable of simultaneous nitrification and denitrification was constructed for aquatic animal experiments in the International Space Station (ISS). The biological filter will be used to remove harmful ammonia excreted from aquatic animals in a closed water circulation system (Aquatic Habitat). The biological filter is a cylindrical

Invasive plant distributions recapitulate patterns found in native plant assemblages in a heterogeneous landscape

Ecosphere, 2015
Diverse alien and native floras of the same region provide a good opportunity to test the influence of environmental variables in structuring of plant assemblages because both can be considered as a replicates of the assembly process under identical ...

Learning algorithms for adaptive digital filtering [PDF]

, 1993
In this thesis, we consider the problem of parameter optimisation in adaptive digital filtering. Adaptive digital filtering can be accomplished using both Finite Impulse Response (FIR) filters and Infinite Impulse Response Filters (IIR) filters. Adaptive

H ? filtering for stochastic singular fuzzy systems with time-varying delay [PDF]

, 2014
This paper considers the H? filtering problem for stochastic singular fuzzy systems with timevarying delay. We assume that the state and measurement are corrupted by stochastic uncertain exogenous disturbance and that the system dynamic is modeled ...

How does habitat filtering affect the detection of conspecific and phylogenetic density dependence? [PDF]

, 2016
Conspecific negative density-dependence (CNDD) has been recognized as a key mechanism underlying species coexistence, especially in tropical forests.

Seasonal Variation of the Effects of Phylogenetic Relatedness and Functional Similarity Among Heterospecific Neighbors and Habitat on Seedling Survival in a Subtropical Forest in Gaoligong Mountains, Southwest China

Ecology and Evolution
Understanding the mechanisms of species coexistence is a long‐standing goal in community ecology. The performance of woody seedlings across different ecological niches has been proposed as a key mechanism in community assembly.
