Data compression for the modal analysis of spatially dense laser Doppler vibrometer measurements
, 2015 This paper investigates a method which can be used to compress two-dimensional mobility shapes measured with scanning laser Doppler vibrometers. It is shown that the compressed data can be used as virtual measurements when estimating modal parameters ...

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 ...

Experimental Modal Analysis of a portable grinder disk [PDF]
, 1991 This paper reports about experimental investigations conducted on disks for portable grinders: the main goal is to state the benefits obtainable with a new type of "damped" disks, that have been developed to reduce the high noise levels caused by ...

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.

Leucine‐rich glioma inactivated 1 (LGI1) is a ganglioside‐binding protein
FEBS Letters, EarlyView.Neuronal hyperexcitability associated with a decrease/absence of the extracellular protein LGI1 has been suggested to be primarily due to the downregulation of Kv1 channel expression. The molecular mechanisms underlying this decrease have not yet been elucidated.
