Journal ArticleDOI
A new computer model for estimating the impact of vaccination protocols and its application to the study of Chlamydia trachomatis genital infections.
TL;DR: Even the least efficacious vaccination programme rapidly decreases the prevalence of C. trachomatis infection in the population, and a vaccine that is efficacious for a period of only 1 year had minimal impact on the prevalenceof the disease in the total population.

Quantification of water transport in plants with NMR imaging
TL;DR: A new nuclear magnetic resonance imaging (NMRi) method is described to calculate the characteristics of water transport in plant stems by comparing the volume flow with the actual volumetric uptake, measured with a balance.
Journal ArticleDOI
Experimental observations of voidage distribution around bubbles in a fluidized bed
TL;DR: In this paper, the authors examined air-fluidized beds of two types of powder (groups A and B of the Geldart classification) using X-rays and the voidage distributions around individual gas bubbles have been determined.

High compression image coding via directional filtering
A. Ikonomopoulos,Murat Kunt +1 more
TL;DR: A new image coding technique is presented as derived from an image decomposition into a low frequency component and many high frequency directional components that led to acceptable results with compression ratios higher than 30 to 1.

Recurrences in the autocorrelation function governing the ultraviolet absorption spectra of O3
Bruce R. Johnson,James L. Kinsey +1 more
TL;DR: The approximate dipole-dipole autocorrelation function corresponding to UV photoabsorption in the Huggins and Hartley bands of ozone is obtained by Fourier transformation of the T=195 K data measured by Freeman, Yoshino, Esmond, and Parkinson as discussed by the authors.
