Numerous evergreen trees and shrubs contain labdane acids, including isocupressic acid, which can cause
late-term abortions in cattle. Recent research has shown that the bark from western juniper trees can
also cause late-term abortions in cattle. Additionally, ranchers have observed that cattle in western juniper-infested
rangelands tend to have decreased...
Let K be a cyclic number field of prime degree ℓ. Heilbronn showed that for a given ℓ there are only finitely many such fields that are norm-Euclidean. In the case of ℓ = 2 all such norm-Euclidean fields have been identified, but for ℓ ≠ 2, little else is...
We document the age and extent of late Quaternary glaciofluvial processes in Garwood Valley, McMurdo Dry Valleys, Antarctica, using mapping, stratigraphy, geochronology, and geochemical analysis of sedimentary and ice deposits. Geomorphic and stratigraphic evidence indicates damming of the valley at its Ross Sea outlet by the expanded Ross Sea ice...
Capelin are a major component of cod diet in many ecosystems of the North Atlantic. In
the Bering Sea, however, the percentage of capelin found in Pacific cod stomachs is negligible. We
hypothesize that the landscape (or ‘seascape’) features of hydrography and bathymetry of the Bering
Sea impose a constraint...
Despite the importance of habitat in determining species distribution and persistence, habitat dynamics are rarely modeled in studies of metapopulations. We used an integrated habitat-occupancy model to simultaneously quantify habitat change, site fidelity, and local colonization and extinction rates for larvae of a suite of Great Plains stream fishes in...
The Manual on Uniform Traffic Control Devices (MUTCD) specifies minimum retroreflectivity
requirements that include an obligation for agencies to develop a strategy for maintaining
compliance. States were given a deadline of January 1, 2012 for the implementation of an
assessment or management plan, which led to an increased emphasis on...
Ebola viruses (EBOV) cause severe disease in humans and nonhuman primates with high mortality rates and continue to emerge in new geographic locations, including several countries in West Africa, the site of a large ongoing outbreak. Phosphorodiamidate morpholino oligomers (PMOs) are synthetic antisense molecules that are able to target mRNAs...
We demonstrate optomechanical quantum control of the internal electronic states of a diamond nitrogenvacancy (NV) center in the resolved-sideband regime by coupling the NV to both optical fields and surface acoustic waves via a phonon-assisted optical transition and by taking advantage of the strong excited-state electron-phonon coupling of a NV...
