This article studies the number of ways of selecting k objects arranged in p circles of sizes n0,...,np−1 such that no two selected ones have less than s objects between them. If ni ≥ sk + 1 for all 0 ≤ i ≤ p − 1, this ...

Epidemiological models and studies of disease ecology typically ignore the role of host condition and immunocompetence when trying to explain the distribution and dynamics of infections and their impact on host dynamics. ...

Objective: In natural populations, infection and condition may act synergistically to trigger a vicious circle: poor condition predisposes to host infections, which further reduce condition, and so on. If this vicious ...

Given the already documented bias in the determination of intersecting remagnetization great circles as a function of the parallelism of the circles, resulting in an elongated bias in that direction, we found that rotational ...
