Two separate analyses were carried out to understand the epidemiology of Bluetongue virus serotype 8 (BTV-8) in 2007 in North West Europe: First, the temporal change in transmission rates was compared to the evolution of temperature during that season. Second, we evaluated the spatio-temporal dynamics of newly reported outbreaks, to estimate a spatial transmission kernel. For both analyses, the...

Infrared absorption in HgCdTe epitaxial material has been investigated using infrared spectromicroscopy to study the uniformity at dimensions representative of typical infrared detectors. Infrared transmission measurements were performed on HgCdTe material using an infrared beam diameter of 9 mm. Line scans and area maps of transmission spectra were obtained to investigate statistical variation...

Far infrared imaging technology is becoming an interesting choice for many civilian uses. We explored the potential of using far infrared camera for human motion analysis, especially from the viewpoint of possible automated image and video analysis. In this article, we present the main characteristics of far infrared imagery that should be of interest to computer vision researchers and seek to ...

This year a large acceptance angle (40x60 mrad) infrared beamline will be put into operation at BESSY II. This highly brilliant infrared source will be used for spectroscopic investigations of biological systems, for microscopy of same and for investigations on the structural and functional interactions of proteins. Vibrational, structural and electronic properties of surfaces and thin layers w...

We have created a map of the large-scale infrared surface brightness in excess of that associated with the atomic interstellar medium, using region-by-region correlations between the far-infrared and 21-cm line surface brightness. Our study updates and extends a previous attempt with the Infrared Astronomical Satellite and Berkeley/Parkes H I surveys. The far-infrared observations used here are...

Empirical “backward” galaxy evolution models for infrared bright galaxies are constrained using multi-band infrared surveys. We developed a new Monte-Carlo algorithm for this task, implementing luminosity dependent distribution functions for the galaxies’ infrared spectral energy distributions (SEDs) and for the AGN contribution, allowing for evolution of these quantities. The adopted SEDs take...

The potential of condensation trails (contrails) from jet aircraft to affect regional-scale surface temperatures has been debated for years, but was difficult to verify until an opportunity arose as a result of the three-day grounding of all commercial aircraft in the United States in the aftermath of the terrorist attacks on 11 September 2001. Here we show that there was an anomalous increase ...

Escherichia coli MC1061 cells were irradiated at 660 and 900 nm, incubated in M9 and LB media with the use of a specially constructed device, and assayed for growth rate. There was a reduction of growth rate stimulation when the irradiated culture was cultivated jointly with the non-irradiated one. In the same time, the irradiated culture extended the invigorate effect on the non-irradiated one...
