—In this paper we present a simple and general new No Free Lunch-like result that applies to revisiting algorithms searching arbitrary problem sets. We begin by unifying the assumptions of closure under permutation and non-revisiting algorithms. We then propose a new approach to reasoning about search algorithm performance, treating search algorithms as(More)
Uncertainties associated with the effects from chronic low-level exposures to radiation prompted us to construct a Low Dose Rate Irradiation Facility (LoDIF). The facility was designed specifically to test the appropriateness of the 10 mGy d(-1) guideline often espoused as acceptable for protection of aquatic biota from ionizing radiation. Scientists at the(More)
A double clock or jetlag mechanism is unlikely to be involved in detection of east-west displacements in a long-distance avian migrant. (2009). Visual but not trigeminal mediation of magnetic compass information in a migratory bird. Age-dependent orientation to magnetically-simulated geographic displacements in migratory Australian silvereyes (Zosterops l.(More)
Despite their potential vulnerability to contaminants from exposure at multiple life stages, amphibians are one of the least studied groups of vertebrates in ecotoxicology, and research on radiation effects in amphibians is scarce. We used multiple endpoints to assess the radiosensitivity of the southern toad (Anaxyrus [Bufo] terrestris) during its(More)
Due to their physical properties, illite clays can sorb cesium-137 almost irreversibly, and therefore sequester contamination from the environment. However, applying large amounts of clay to natural aquatic habitats for in situ remediation purposes may create conditions of high turbidity and sedimentation. To evaluate potential effects of turbidity from(More)
The dose to human and nonhuman individuals inflicted by anthropogenic radiation is an important issue in international and domestic policy. The current paradigm for nonhuman populations asserts that if the dose to the maximally exposed individuals in a population is below a certain criterion (e.g., <10 mGy d(-1)) then the population is adequately protected.(More)
