A Bernstein-Like Trigonometric Basis: Properties, Curve Design, and Operator Construction
Journal of Applied MathematicsWe introduce a novel family of trigonometric basis functions equipped with a shape parameter, analogous to Bernstein functions. These basis functions are employed to construct Bézier-like curves, termed “trigo-curves”, which retain the fundamental ...

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 ...

Preserving properties of some Szasz-Mirakyan type operators
Journal of Numerical Analysis and Approximation TheoryFor a family of Szasz-Mirakyan type operators we prove that they preserve convex-type functions and that a monotonicity property verified by Cheney and Sharma in the case Szasz-Mirakyan operators holds for the variation study here.

Abstract and Applied Analysis, 2014 Summary: We introduce a \(q\)-generalization of Szász-Mirakjan operators \(S_{n, q}\) and discuss their properties for fixed \(q \in(0,1)\). We show that the \(q\)-Szász-Mirakjan operators \(S_{n, q}\) have good shape-preserving properties. For example, \(S_{n, q}\) are variation-diminishing, and preserve monotonicity, convexity, and concave modulus of

FEBS Letters, EarlyView.Proteostasis and the gut microbiota play a key role in shaping host physiology. Microbiota‐derived metabolites, vitamins, and RNA modulate host proteostasis. Findings from model systems, including C. elegans, indicate microbes can either stabilize or disrupt host proteostasis.

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.

Design and analysis strategies for robust microbiome ageing research
FEBS Letters, EarlyView.The gut microbiome changes with age and associates with age‐related morbidity and mortality, establishing it as a potential biomarker and intervention target for ageing. Realising this potential requires methodological rigour, yet distinguishing biological signals from methodological artefacts remains challenging across cohorts. This review provides an

On a class of shape-preserving refinable functions with dilation 3 [PDF]
, 2013 We analyze the properties of a class of shape-preserving refinable functions with dilation M = 3. We give an algorithm to construct totally positive bases with optimal shape-preserving properties on a finite interval.

Reconstructing enzyme evolution by protein engineering
FEBS Letters, EarlyView.Natural enzyme evolution can be retraced by protein engineering methods such as directed evolution, rational design, and ancestral sequence reconstruction. These approaches reveal how enzymes emerged from ligand‐binding scaffolds, developed varying substrate preferences, formed oligomeric complexes, adapted to environmental changes, and evolved novel ...
