Enhanced Light Absorption by Horizontally Oriented Diatom Colonies
Frontiers in Marine Science, 2020 Through in situ holographic imaging of undisturbed water, diatom colonies with high aspect ratios have been found to exhibit preferential horizontal orientation within high biomass subsurface layers.

FEBS Letters, EarlyView.Mycobacterial 3‐methylcrotonyl‐CoA carboxylase uses a mobile biotin‐carrying domain to shuttle a carboxyl group between two catalytic sites, enabling carboxylation of 3‐methylcrotonyl‐CoA during leucine breakdown. Cryo‐electron microscopy captures the carrier at both sites and reveals an inward loop movement that may prevent futile rebinding to the ...

Optical interconnection networks based on microring resonators [PDF]
, 2012 Optical microring resonators can be integrated on a chip to perform switching operations directly in the optical domain. Thus they become a building block to create switching elements in on-chip optical interconnection networks, which promise to overcome

Elastic and inelastic scattering of the 14C + 18O nuclei [PDF]
Ядерна фізика та енергетика, 2010 New angular-distribution data of 14С + 18О elastic and inelastic scattering at the energy Elab(18O) = 105 MeV were obtained firstly. The data were analysed within the optical model and coupled-reaction-channels methods including contributions from most ...

The Shewanella oneidensis Fic enzyme SoFic targets the switch‐I region of EF‐Tu for AMPylation
FEBS Letters, EarlyView.Fic enzymes mediate diverse post‐translational modifications across all domains of life, including AMPylation. Prokaryotic EF‐Tu can be AMPylated and deAMPylated by the conserved Fic enzyme SoFic. Structural and biochemical approaches were used to characterize the effect of AMPylation on EF‐Tu, SoFic's enzymatic activities, and the enzyme‐target ...

Global potential of interaction for 16O + 12C- and 12C + 12C-diffractive scattering in the wide energy range [PDF]
Ядерна фізика та енергетика, 2014 Detailed study of the behavior of experimental differential cross sections for the 16О + 12С-, 12С + 12С-elastic scatte¬ring in the energy range from 1 to 200 MeV/nucleon have been carried out. It is found that differential cross sections in the range of

FEBS Letters, EarlyView.Synechocystis strains deficient in succinate dehydrogenase (SDH) secrete more succinate than the WT under dark anaerobic conditions, supporting that SDH then primarily acts as SDH, not as a fumarate reductase. L‐aspartate oxidase (Laspo) from Synechocystis is functional under anaerobic conditions, reducing fumarate to succinate.

State‐space models for optical imaging [PDF]
Statistics in Medicine, 2007 AbstractMeasurement of stimulus‐induced changes in activity in the brain is critical to the advancement of neuroscience. Scientists use a range of methods, including electrode implantation, surface (scalp) electrode placement, and optical imaging of intrinsic signals, to gather data capturing underlying signals of interest in the brain.
