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.

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 ...

Intermediate Models in Nonlinear Optics [PDF]

SIAM Journal on Mathematical Analysis, 2005
This paper deals with models for the simulation of the propagation of laser pulses in a nonlinear medium. The new model turns out to be exact in linear cases, but take into account the nonlinear effects; some numerical results are presented to illustrate the error bounds and to investigate the numerical effectivity of the model.

Linking neurogenesis, oligodendrogenesis, and myelination defects to neurodevelopmental disruption in primary mitochondrial disorders

FEBS Letters, EarlyView.
Mitochondrial remodeling shapes neural and glial lineage progression by matching metabolic supply with demand. Elevated OXPHOS supports differentiation and myelin formation, while myelin compaction lowers mitochondrial dependence, revealing mitochondria as key drivers of developmental energy adaptation.

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

Optical information processing based on an associative-memory model of neural nets with thresholding and feedback [PDF]

, 1985
The remarkable collective computational properties of the Hopfield model for neural networks [Proc. Nat. Acad. Sci. USA 79, 2554 (1982)] are reviewed. These include recognition from partial input, robustness, and error-correction capability.

Measurement of the surface susceptibility and the surface conductivity of atomically thin $\rm MoS_2$ by spectroscopic ellipsometry

, 2017
We show how to correctly extract from the ellipsometric data the surface susceptibility and the surface conductivity that describe the optical properties of monolayer $\rm MoS_2$.

Organizing the interface—Plasma membrane architecture and receptor dynamics in virus‐cell interactions

FEBS Letters, EarlyView.
Plasma membranes contain dynamic nanoscale domains that organize lipids and receptors. Because viruses operate at similar scales, this architecture shapes early infection steps, including attachment, receptor engagement, and entry. Using influenza A virus and HIV‐1 as examples, we highlight how receptor nanoclusters, multivalent glycan interactions ...
