It is shown that non-adiabatic cosmological perturbations cannot appear during the period of reheating following inflation with a single scalar inflaton field. Electronic address: [email protected] According to a widely adopted picture [1], the perturbations to the Robertson– Walker cosmology arose from the quantum fluctuations in a slowly rolling scalar “inflaton” field during a peri...

Amplification of oncogenes has been found to be an important prognostic factor in behavior of patients' malignancies. In this study we have used new gel electrophoresis techniques to follow the location of amplified c-myc oncogene sequences in HL-60 promyelocytic leukemia cells. In passages 46-62 of the cells, the cells contain amplified c-myc sequences on submicroscopic circular extrachromosom...
