This is in contrast to density-dependent factors that strongly affect limiting populations of organisms once it reaches a certain level (e.g., diseases). What are 2 examples of density independent factors? The two examples of density independent factors are natural disasters and human activity. ...
cell density‑dependent nucleocytoplasmic shuttling proteins and open chromatin Kangjing Li ,Yaxin Li & Fumihiko Nakamura * The contact inhibition of proliferation (CIP) denotes the cell density-dependent inhibition of growth, and the loss of CIP represents a hallmark of cancer....
The thickness of the cathode sheath is the minimum distance between cathode and anode, which is dependent on gas species, pressure, and cathode materials. The positive column is not necessary here, although it is what people need in plasma applications. The plasma current of a glow discharge ...
A density matrix is basis-dependent, but the trace of it is invariant with respect to a transformation of basis. The density matrix of a state is not unique. Different superpositions may have the same density matrix: (3.12)|ψ1〉=12|0〉+12(12(|0〉−|1〉)), (3.13)|ψ2〉=134(32...
Real-time time-dependent density-functional theory (RT-TDDFT) and linear response time-dependent density-functional theory (LR-TDDFT) are two important approaches to simulate electronic spectra. However, the basis sets used in such calculations are usual
Unlike other resources, quantum coherence is a basis dependent quantity, a quantum state ρ is said to be incoherent in a given reference basis \(\{ \vert i \rangle \}\), if the state is diagonal in this basis, i.e., if \(\rho = {\sum_{i}}p_{i} \vert i \rangle \langle ...
It is often stated that evolution maximizes growth rate in the absence of densitydependence, and equilibrium population density in the presence of density regulation, provided there are no frequency-dependent processes. Although originally derived in unstructured models, both maximization principles have be...

or that it is τ-dependent in the sense of Dedecker and Prieur (2005). These dependence conditions are presented in Section 2 and motivated through various examples. In density deconvolution, two factors determine the estimation accuracy. First, the smoothness of the density g to be estimated,...
Selected long-term field monitoring studies, manipulative studies and computer modelling examples are then highlighted that illustrate how density-dependent processes led to compensatory responses at the population level. Some theoretical and empirical advances that offer hope for progress in the future on...
