Elements in the 5′ Untranslated Region of Viral RNA Important for HIV Gag Recognition and Cross-Packaging

Viruses
During retrovirus assembly, Gag packages unspliced viral RNA as the virion genome. Genome packaging is usually specific with occasional exceptions of cross-packaging RNA from distantly related retroviruses.

Probing the last scattering surface through the recent and future CMB observations

, 2008
We have constrained the extended (delayed and accelerated) models of hydrogen recombination, by investigating associated changes of the position and the width of the last scattering surface.

How to recover from a bad start: adaptation of HIV-1 transcription start site mutants during serial passaging in culture

Journal of Virology
HIV-1 uses neighboring sequences as transcription start sites and generates multiple unspliced transcripts, including two major transcripts with three guanosines (3G) or one guanosine (1G) at the 5′ end. Although only differing by 2-nt, 3G RNA and 1G RNA

Electrical and photoelectrical properties of MoN/n-Si surface-barrier structures [PDF]

Радиофизика и электроника, 2019
Subject and purpose. The subject of research is the electrical and photoelectric properties of the МoN/n-Si heterostructure fabricated for the first time by means of the deposition of thin film of molybdenum nitride (n-type conductivity) by the reactive ...

Whole genome phylogenies reflect the distributions of recombination rates for many bacterial species

eLife, 2021
Although recombination is accepted to be common in bacteria, for many species robust phylogenies with well-resolved branches can be reconstructed from whole genome alignments of strains, and these are generally interpreted to reflect clonal relationships.

Structural snapshots of Xer recombination reveal activation by synaptic complex remodeling and DNA bending [PDF]

, 2016
Bacterial Xer site-specific recombinases play an essential genome maintenance role by unlinking chromosome multimers, but their mechanism of action has remained structurally uncharacterized. Here, we present two high-resolution structures of Helicobacter

Recombination in Perovskite Solar Cells: Significance of Grain Boundaries, Interface Traps, and Defect Ions

ACS Energy Letters, 2017
Trap-assisted recombination, despite being lower as compared with traditional inorganic solar cells, is still the dominant recombination mechanism in perovskite solar cells (PSCs) and limits their efficiency.

Temperature dependence of binary and ternary recombination of H3+ ions with electron [PDF]

, 2009
We study binary and the recently discovered process of ternary He-assisted recombination of H3+ ions with electrons in a low temperature afterglow plasma.

Hybrid Perovskites for Photovoltaics: Charge-Carrier Recombination, Diffusion, and Radiative Efficiencies.

Accounts of Chemical Research, 2016
Photovoltaic (PV) devices that harvest the energy provided by the sun have great potential as renewable energy sources, yet uptake has been hampered by the increased cost of solar electricity compared with fossil fuels.

The effects of recombination rate on the distribution and abundance of transposable elements [PDF]

, 2008
Transposable elements (TEs) often accumulate in regions of the genome with suppressed recombination. But it is unclear whether this pattern reflects a reduction in the efficacy of selection against deleterious insertions or a relaxation of ectopic ...
