In ungulates, parturition is correlated with a reduction in movement rate. With advances in movement-based technologies comes an opportunity to develop new techniques to assess reproduction in wild ungulates that are less invasive and reduce biases. DeMars et al. (2013, Ecology and Evolution 3:4149-4160) proposed two promising new methods (individual- and population-based; the DeMars model) tha...

is a member of URSI Commission B, a senior member of the IEEE, and a member of the Eta Kappa Nu and Sigma Xi honor societies. He has approximately 100 journal and conference publications in the field of electromagnetics. His current research interests include electromagnetic and guided-wave theory, electromagnetic propagation and radiation in complex media and structures and electromagnetic mat...

Modelled results are presented for an on-glass car antenna designed primarily for reception at VHF. A discussion is given as to the electromagnetic significance of various parts of the car structure with respect to received pattern shape and computational efficiency. The simulated results are verified by comparison with measurement.

• Approximately 48,000 FAA employees who provide air traffic control, flight service, security, field maintenance, certification, systems acquisitions, and a variety of other services. • Approximately 13,000 instrument flight procedures, including over 1,000 Instrument Landing System (ILS) procedures, over 1,700 nondirectional beacon (NDB) procedures, over 2,700 VHF omnidirectional range (VOR) ...

The most important features of microcrystalline silicon (Fc-Si:H) and microcrystalline silicon based p-i-n solar cells (specially those deposited by VHF-Glow Discharge) are reviewed. Since such material has been recognized to be a photovoltaically active material, stabilized cell efficiencies have steadily risen and have now reached 12% in the so called “micromorph” (microcrystalline/amorphous)...

Argentine hemorrhagic fever (AHF) is an endemo-epidemic disease caused by Junín virus (JUNV), a member of the arenaviridae family. Although a recently introduced live attenuated vaccine has proven to be effective, AHF remains a potentially lethal infection. Like in other viral hemorrhagic fevers (VHF), AHF patients present with fever and hemorrhagic complications. Although the causes of the ble...

CDC designated category A infectious agents pose a major risk to national security and require special action for public health preparedness. They include viruses that cause viral hemorrhagic fever (VHF) syndrome as well as variola virus, the agent of smallpox. VHF is characterized by hemorrhage and fever with multi-organ failure leading to high morbidity and mortality. Smallpox, a prior scourg...

Scintillations on VHF radio signal are sparsely observed during daytime due to unavailability of strong electron density irregularities in equatorial E or F region. Type I/II irregularities observed at E region altitudes during the daytime are linked with either two-stream or gradient drift instability. The occurrence of these irregularities in presence of strong blanketing Es (Esb) can produce...

BACKGROUND The dihydroazulene (DHA)/vinylheptafulvene (VHF) system (with two cyano groups at C1) functions as a photo-/thermoswitch. Direct ionic bromination of DHA has previously furnished a regioselective route to a 7,8-dibromide, which by elimination was converted to a 7-bromo-substituted DHA. This compound has served as a central building block for functionalization of the DHA by palladium-...
