Using individual tracking data to validate the predictions of species distribution models
The authors would like to thank the College of Life Sciences of Aberdeen University and Marine Scotland Science which funded CP's PhD project. Skate tagging experiments were undertaken as part of Scottish Government project SP004. We thank Ian Burrett for help in catching the fish and the other fishermen and anglers who returned tags. We thank José Manuel Gonzalez-Irusta for extracting and making available the environmental layers used as environmental covariates in the environmental suitability modelling procedure. We also thank Jason Matthiopoulos for insightful suggestions on habitat utilization metrics as well as Stephen C.F. Palmer, and three anonymous reviewers for useful suggestions to improve the clarity and quality of the manuscript.Peer reviewedPostprintPostprintPostprintPostprintPostprin
Many-particle Majorana bound states: derivation and signatures in superconducting double quantum dots
We consider two interacting quantum dots coupled by standard superconductors.
We derive an effective Hamiltonian, and show that over a wide parameter range a
degenerate ground state can be obtained. An exotique form of Majorana bound
states are supported at these degeneracies, and the system can be adiabatically
tuned to a limit in which it is equivalent to the one-dimensional wire model of
Kitaev. We give the form of a Majorana bound state in this system in the strong
interaction limit in the many-particle picture. We also study the Josephson
current in this system, and demonstrate that a double slit-like pattern emerges
in the presence of an extra magnetic field. This pattern is shown to disappear
with increasing interaction strength, which is able to be explained as the
current being carried by chargeless Majorana modes.Comment: 13 pages, 7 figures. Updated paper includes more details regarding
the derivation of the effective Hamiltonia
Effects of a physiotherapy and occupational therapy intervention on mobility and activity in care home residents: a cluster randomised controlled trial
Objective To compare the clinical effectiveness of a programme of physiotherapy and occupational therapy with standard care in care home residents who have mobility limitations and are dependent in performing activities of daily living
G80-521 Common Stalk Borer in Corn (Revised April 2000)
The life history and appearance of common stalk borers is described, along with information on damage they can cause, economic injury levels and ways to control them in corn. In the past, the common stalk borer, Papaipema nebris, has not been a major pest of corn in Nebraska. Stalk borer damage in corn commonly is confined to occasional plants in the first few rows near field margins, fence rows, grass terraces and waterways. In addition to attacking corn, this insect attacks over one hundred other species of plants, including ornamentals, broadleaf weeds and grasses. It may feed on soybeans as well, but is not an economically important pest of that crop. Understanding the common stalk borer life cycle and behavior is critical to selecting management practices to reduce its damage in corn
