Atlantic atmospheric aerosol studies: 1. Program overview and airborne lidar

Autor: J. M. Vaughan, T. Swirbalus, S. B. Alejandro, P. H. Davies, R Foord, D. J. Wilson, G. G. Koenig, D. Bedo, C. Nash, R. Callan, D. W. Brown, J. Woffinden, R. Frelin

Publikováno v: Journal of Geophysical Research: Atmospheres. 100:1035-1041

During the period 1988-1990, studies of atmospheric aerosol have been made over the Atlantic. These include measurement programs out of Ascension Island (8{degrees}S, 14{degrees}W), the Azores (38{degrees}N, 25{degrees}W), Iceland (63{degrees}N, 23{d

Coherent Laser Radar and the Problem of Aircraft Wake Vortices

Autor: R. Foord, G. D. J. Constant, J.M. Vaughan, P. A. Forrester

Publikováno v: Journal of Modern Optics. 41:2153-2173

Aircraft wake vortices have been studied with a 10·6 μm coherent c.w. lidar. Good agreement is found between the form of experimentally observed Doppler spectra and theoretical calculations and modelling. Detailed measurements of spectra have yield

Correlation Analysis of Fluctuations in Coherent Lidar Signals at 10·6 μm

Autor: R. Foord, P. H. Davies, J. M. Vaughan, R. Callan, W. R. M. Pomeroy, D. W. Brown

Publikováno v: Journal of Modern Optics. 38:623-648

Signal fluctuations in a coherent, continuous-wave, lidar operating at 10·6 μm were investigated by forming temporal autocorrelation functions of intensity. The scattered radiation was taken from a model target consisting of a moving belt, and was

Detector performance studies for CO2 laser heterodyne systems

Autor: J.M. Vaughan, G. D. J. Constant, D. J. Wilson, R. Foord

Publikováno v: Infrared Physics. 31:109-115

Performance studies of a group of detectors used in CO 2 heterodyne lidar systems have been carried out. Even for nominally identical detectors considerable differences were found. For one detector near ideal behaviour with up to 13 dB of local oscil

X-ray structural analysis of the yeast cell cycle regulator Swi6 reveals variations of the ankyrin fold and has implications for Swi6 function

Autor: R, Foord, I A, Taylor, S G, Sedgwick, S J, Smerdon

Publikováno v: Nature structural biology. 6(2)

Swi6 is a 92,000 Mr protein common to two distinct transcriptional activation complexes (SBF and MBF) that coordinate gene expression at the G1-S boundary of the yeast cell cycle. The X-ray structure of a central 36,000 Mr fragment has been determine

Structural and functional architecture of the yeast cell-cycle transcription factor swi6

Autor: S G, Sedgwick, I A, Taylor, A C, Adam, A, Spanos, S, Howell, B A, Morgan, M K, Treiber, N, Kanuga, G R, Banks, R, Foord, S J, Smerdon

Publikováno v: Journal of molecular biology. 281(5)

The structural and functional organisation of Swi6, a transcriptional regulator of the budding yeast cell cycle has been analysed by a combination of biochemical, biophysical and genetic methods. Limited proteolysis indicates the presence of a approx

Lidar Measurements at Heathrow and Structure in the B747 Vortex

Autor: J.M. Vaughan, D. Brown, G. Constant, J. Eacock, R. Foord

Publikováno v: Coherent Laser Radar.

The wake vortices of nearly 2000 aircraft landing at Heathrow have been recorded with a CW CO2 Lidar. Very characteristic differences are apparent, including clear evidence of structure within the B747 vortex.
