Viruses that originate in bats may be the most notorious emerging zoonoses that spill over from wildlife into domestic animals and humans. Understanding how these infections filter through ecological systems to cause disease in humans is of profound importance to public health. Transmission of viruses from bats to humans requires a hierarchy of enabling… (More)
Hendra virus is a recently emerged bat-borne zoonotic agent with high lethality in horses and humans in Australia. This is a rare disease and the determinants of bat to horse transmission, including the factors that bring these hosts together at critical times, are poorly understood. In this cross-disciplinary study climatic and vegetation primary… (More)
A more rigorous and nuanced understanding of land-use change (LUC) as a driver of emerging infectious disease (EID) is required. Here we examine post hunter-gatherer LUC as a driver of infectious disease in one biogeographical region with a compressed and documented history--continental Australia. We do this by examining land-use and native vegetation… (More)
With hip fracture and dementia increasing in incidence in the global ageing population, there is a need for the development of specific procedures targeting optimal treatment outcomes for these patients. This paper looks primarily at the factors that limit access to subacute rehabilitation services as a growing body of evidence suggests that access to… (More)
A laser oscillator has been operated in which one reflector is a self-pumped phase-conjugate mirror. The laser is tunable and employs rhodamine 6G as a broadband gain medium. The oscillating linewidth was measured to be 2 GHz at half-power points.
The postmortem findings of an adult male Adelie penguin found at Magnetic Island, East Antarctica, demonstrating a premortem wound in addition to those consistent with an attack and scavenging by south polar skuas, are described. Other causes of mortality are discussed.
Laser operation at 2.8 microm in BaY(2)F(8) with erbium concentrations of 7.5% and 20% is investigated under laser-diode pumping at 967 nm. Output powers as high as 250 mW and slope efficiencies as high as 24% are obtained. Results are comparable with those of Er(3+):LiYF(4) under the same pump conditions. Slope efficiencies above 30% are predicted for… (More)
We present experimental results demonstrating strong velocity-distribution modification in a specific atomic state using optical pumping between hyperfine split levels. These results show that the velocity of a specific state can be defined within 6%, corresponding to a local temperature of 1 K. The velocity-specific-state selection is accomplished by using… (More)
A high-power semiconductor diode-laser array operating at 797 nm has been used to pump an Er:YLiF(4) upconversion laser with output at 551 nm operating at 48 K. By carefully controlling the beam geometry and oscillating linewidth of the diode-pumped laser, it has been possible to obtain 100 mW of visible output power with a conversion efficiency from the IR… (More)
