FEBS Letters, EarlyView.We reconstituted Synechocystis glycogen synthesis in vitro from purified enzymes and showed that two GlgA isoenzymes produce glycogen with different architectures: GlgA1 yields denser, highly branched glycogen, whereas GlgA2 synthesizes longer, less‐branched chains.

Parametric study of the behaviour of group velocity dispersion in optical pulse compression [PDF]
, 1992 An optical pulse compressor is investigated over a large range of compression factors, fiber lengths and laser powers. The given theory for zero group velocity dispersion is valid over the investigated range of grating-prism distances.

Calpain small subunit homodimerization is robust and calcium‐independent
FEBS Letters, EarlyView.Calpains dimerize via penta‐EF‐hand (PEF) domains. Using single‐molecule force spectroscopy, we measured the strength and kinetics of PEF–PEF homodimer binding. The interaction is robust, shows a transient conformational step before dissociation, and remains largely insensitive to Ca2+.

Negative Group Velocity Plasmons Propagating in Waveguides Composed of Graphene Metamaterials
IEEE Access, 2020 Fast light which demonstrates negative group velocity, is achieved by the anomalous dispersion or photon tunneling. However, many applications based on the fast light are limited due to the disadvantages of inferior tunability or nonlinear dispersion ...

Galaxy groups: abundance by luminosity and by velocity dispersion [PDF]
Monthly Notices of the Royal Astronomical Society, 1993 We present a reanalysis of groups in the Center for Astrophysics redshift survey, focusing on properties that can be readily compared with predictions of gravitational clustering theories. The grouping algorithm we employ is optimized using artificial catalogues constructed from N-body simulations that have similar low-order correlations to those of ...

Structural insights into an engineered feruloyl esterase with improved MHET degrading properties
FEBS Letters, EarlyView.A feruloyl esterase was engineered to mimic key features of MHETase, enhancing the degradation of PET oligomers. Structural and computational analysis reveal how a point mutation stabilizes the active site and reshapes the binding cleft, expading substrate scope.

Group velocity of the probe light in semiconductor–metal molecules
, 2012 The group velocity of light is investigated in a hybrid nanostructure comprised of semiconductor quantum dot (SQD) and metal nanoparticle (MNP). In the presence of MNP, the hybrid absorption of the system can be eliminated and forms a broad transparency ...

Pulse splitting in the anomalous group-velocity-dispersion regime
Optics Express, 2011 We investigate experimentally the role that the initial temporal profile of ultrashort laser pulses has on the self-focusing dynamics in the anomalous group-velocity dispersion (GVD) regime. We observe that pulse-splitting occurs for super-Gaussian pulses, but not for Gaussian pulses.

Modelling stem cell differentiation related processes—A practical overview for biologists
FEBS Letters, EarlyView.Stem cell differentiation is complex and difficult to control experimentally. This review introduces suitable computational modelling approaches that can support stem cell research, from mechanistic ODE and abstract models to multiscale and deep learning methods.
