The Effects of Suburbanization on Nest Ectoparasites and Nest Defense Behavior in the Wood Thrush
Wood Thrush nesting ecology ectoparasite nest defense
2015/1/4
The Wood Thrush (Hylocichla mustelina) is declining throughout its range, yet is capable of persisting in both contiguous forests and small forest patches surrounded by human suburban development. Thu...
Hydrocarbons on Harvester Ant (Pogonomyrmex barbatus) Middens Guide Foragers to the Nest
Pogonomyrmex barbatus.Hydrocarbons Homing .Chemical ecology Foraging behavior
2015/12/10
Colony-specific cuticular hydrocarbons are used
by social insects in nestmate recognition. Here, we showed
that hydrocarbons found on the mound of Pogonomyrmex
barbatus nests facilitate the return ...
Characterizations of all-derivable points in nest algebras
All-derivable point nest algebra derivable linear mapping at G
2011/9/1
Abstract: Let $\mathcal{A}$ be an operator algebra on a Hilbert space. We say that an element $G\in {\mathcal{A}}$ is an all-derivable point of ${\mathcal{A}}$ if every derivable linear mapping $\phi$...
NEST: A Comprehensive Model for Scintillation Yield in Liquid Xenon
Ionization and excitation processes Noble-liquid detectors Scintillators, scintillation and light emission processes Simulation methods and programs
2011/8/31
A comprehensive model for explaining scintillation yield in liquid xenon is introduced.We unify various definitions of work function which abound in the literature and incorporate all available data o...
Nest Site Characteristics and Nest Densities of Ardieds (Night Heron: Nycticorax nycticorax, Grey Heron: Ardea cinerea, and Little Egret: Egretta garzetta) in the Nallıhan Bird Sanctuary (Sarıyar Reservoir, Ankara, Turkey)
Nest densities ardeid species Nallı han Bird Sanctuary
2010/3/25
In this study, the nesting site characteristics and nest densities of ardeids (grey heron: Ardea cinerea; night heron: Nycticorax nycticorax, and little egret: Egretta garzetta) were investigated in N...
The Existence of Maximal $W^*$-Closed Submodules in Nest Algebra Modules
Finite-partition submodule Finite Finite rank operator $w^{*}$-closure
2007/12/11
Using the technique of annihilators, we characterize the $w^{*}$-closure of the finite-partition submodule ${{\mathscr R}({\mathscr N}, \sim)}$ of a weakly closed nest algebra module ${\mathscr U}$ co...
Nest代数的某些范数闭理想
Nest代数 Jacobson根 闭双边理想 广义Ringrose特征
2007/12/10
设$R_N$是Ｎｅｓｔ代数ａｌｇＮ的Ｊａｃｏｂｓｏｎ根，用$J_N^n$表示由$R_N^n=\{T_1T_2\codts T_n;\forall T_i\in R^N,1\leq i\leq n\}$；生成的ａｌｇＮ的范数闭双边理想。Ｊ．Ｒ．Ｒｉｎｇｒｏｓｅ［１，定理５．４］给出了$R_N$的Ｋ１ｎｇｒｏｓｅ特征，本文将给出$J_N^n$具有广义Ｒｉｎｇｒｏｓｅ特征的充分必要条件，这个结果是［１...
