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.

Diversity and complexity in neural organoids
FEBS Letters, EarlyView.Neural organoid research aims to expand genetic diversity on one side and increase tissue complexity on the other. Chimeroids integrate multiple donor genomes within single organoids. Self‐organising multi‐identity organoids, exogenous cell seeding, or enforced assembly of region‐specific organoids contribute to tissue complexity.

Nonlinear dynamics problems: mathematical models of viscoelastic isotropic plates and shells with smoothly variating thickness (asymmetrical cases) [PDF]
Инженерно-строительный журнал, 2010 More complete mathematical models for the dynamic problems of the isotropic plates and shells with smoothly variatind thickness (asymmetrical cases), which help taking into account both geometrical nonlinearity and possible creeping (viscoelacticity) of ...

FEBS Letters, EarlyView.Ascidian Ciona larvae initially show strong clockwise tail twisting, which is largely corrected during development. However, a small residual twist remains. This study shows that organized helical myofibrils in tail muscles mechanically stabilize this residual asymmetry, preventing complete restoration of bilateral symmetry and revealing how embryos ...

THE TRACKED VEHICLE MOTION MATHEMATICAL MODEL BASED ON GIBBS-APPELL EQUATIONS
Sučasnì Informacìjnì Tehnologìï u Sferì Bezpeki ta Oboroni, 2015 This article is dedicated to the study of the curvilinear motion of tracked vehicles on the plane. Based on the Gibbs-Appell equations the mathematical model of the tracked vehicle on the two-dimensional surface has been formulated as a mechanical system

FEBS Letters, EarlyView.We present robust protocols for the preparation of supported lipid bilayers (SLBs) incorporating either Salmonella smooth LPS or outer membrane vesicles (OMVs). We use a combination of quartz crystal microbalance with dissipation (QCM‐D) and fluorescence microscopy to both characterize the SLBs of various compositions and to probe their interactions ...

Motion Planning Algorithm of a Multi-Joint Snake-Like Robot Based on Improved Serpenoid Curve
IEEE Access, 2020 In order to study the winding motion of a multi-joint snake-like robot with multi-degree of redundancy in plane, a motion planning algorithm of a multi-joint snake-like robot based on improved Serpenoid curve equation is proposed in this paper.
