In this article, we address the physics of the generation of images of surface structures imprinted into the target back surface with laser-accelerated protons.
The zone is 170 m thick, and ammonoids and other fossils occur as imprints in mudstones and as shell-rich layers in sandy turbidites.
We have used bisulphite sequencing to analyse the methylation status of key imprinting control regions, thereby clarifying the basis of these observations.
Although associated with a particular body, the soul is not imprinted in it.
External doors seem to be completely absent, and many ladder imprints have been found in the wall plaster at the site.
Allele-specific expression and total expression levels of imprinted genes during early mouse development : implications for imprinting mechanisms.
In the tumour samples, however, the methylation imprints are uncoupled.
An estimated 150 imprinted genes are as yet unidentified, and their roles not yet understood.
The pink and blue bars represent the acquisition of the maternal and paternal imprints, respectively.
In this example, the maternal allele is imprinted.
Possibly imprinting does not efficiently penetrate through many asexual generations.
Consequently, imprinting should not occur in oviparous taxa.
She has left indestructible imprints on one-fourth of the human race in the course of a long succession of centuries.
Initial imprints on a planar target sur face were given with an intensity-modulated laser beam.
We propose a set of measurements of such "isotopic imprints" with accelerator mass spectrometry.
