Amplicon residues in research laboratories masquerade as COVID-19 in surveillance tests
(Elsevier BV, 2021-04)Asymptomatic surveillance testing together with COVID-19-related research can lead to positive SARS-CoV-2 tests resulting not from true infections, but non-infectious, non-hazardous by-products of research (amplicons). ... -
Amplification of a broad transcriptional program by a common factor triggers the meiotic cell cycle in mice
(eLife Sciences Publications, Ltd, 2019-02)The germ line provides the cellular link between generations of multicellular organisms, its cells entering the meiotic cell cycle only once each generation. However, the mechanisms governing this initiation of meiosis ... -
Amplification of Local Instabilities in a Bose-Einstein Condensate with Attractive Interactions
(American Physical Society, 2003-04)We study the collapse of large homogeneous Bose-Einstein condensates due to intrinsic attractive interactions. We observe the amplification of a local instability by seeding a momentum state p and suddenly switching the ... -
Amplification of Picosecond Pulses in a 140-GHz Gyrotron-Traveling Wave Tube
