Most natural populations experience some density dependence, and longterm average rates of population growth are likely to be close to zero (i.e., steady state). An essential question, therefore, is how and to what extent do density-dependent effects influence the responses of populations to toxicant impacts? Here we consider three general types of interaction between density dependence and tox...

Bare vs effective pairing forces. A microscopic finite-range interaction for HFB calculations in coordinate space. Abstract We propose a microscopic effective interaction to treat pairing correlations in the 1 S 0 channel. It is introduced by recasting the gap equation written in terms of the bare force into a fully equivalent pairing problem. Within this approach, the proposed interaction repr...

The electron-electron relaxation in impure two-dimensional superconductors is studied. All channels of the electron-electron interaction classified in the Nambu representation are taken into account. It is shown that the recombination relaxation rate originates from quasipartical processes associated with fluctuations of the electron density and the phase of the order parameter. At low temperat...

We report a comprehensive evaluation of the topological structure of protein-protein interaction (PPI) networks by mining and analyzing graphs constructed from the popular data sets publicly available to the bioinformatics research community. We compare the topology of these networks across different species, different confidence levels, and different experimental systems used to obtain the int...

Long-term studies of two-species interactions under field conditions are unusual; most long-term field studies are of single species dynamics (1-6). Concurrent long-term studies on the dynamics of the same two interacting species in different locations are very rare. This result has led to the tacit assumption that different cases of the same two-species interaction would involve essentially qu...

We investigate the Ruderman-Kittel-Kasuya-Yosida (RKKY) interaction between magnetic impurities in both single layer and Bernal stacked bilayer graphene, finding a number of striking anomalies in the temperature dependence of this interaction. In undoped single layer graphene the strength of the RKKY interaction for substitutional impurities anomalously increases upon increasing temperature, an...

The presence of spin-orbit (SO) interaction in a noncentrosymmetric superconductor, La2C3 (Tc ≃ 11 K) is demonstrated by muon spin rotation (μSR) in its normal state, where μSR spectra exhibit field-induced weak depolarization due to van Vleck-like local susceptibility. In the mixed state, muon spin relaxation due to inhomogeneity of internal field (σv) exhibits a field dependence that is chara...

The notion of hit-or-miss dependence is introduced to describe spatial dependence of random closed sets, and its closure properties under various set operations are derived. The hit-or-miss dependence is then applied to Boolean germ-grain models to study local interactions within each grain. The dependence comparison results obtained not only show how local interactions of Boolean germ-grain mo...

density-dependence by using partial correlation coefficients as a test statistic. The extended tests detected delayed density-dependence in 8 15 time series (8.9% 16.7%) at the 5% level (two-tailed test). 5. The high incidence of direct density-dependence and the low, but significant, incidence of delayed density-dependence in these vole populations are discussed. Delayed maturation at high den...
