Modulus of smoothness and theorems concerning approximation on compact groups
International Journal of Mathematics and Mathematical Sciences, 2003 We consider the generalized shift operator defined by (Shuf)(g)=∫Gf(tut−1g)dt on a compact group G, and by using this operator, we define spherical modulus of smoothness. So, we prove Stechkin and Jackson-type theorems.

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.

On New Modifications Governed by Quantum Hahn’s Integral Operator Pertaining to Fractional Calculus
Journal of Function Spaces, 2020 In the article, we present several generalizations for the generalized Čebyšev type inequality in the frame of quantum fractional Hahn’s integral operator by using the quantum shift operator σΨqς=qς+1−qσς∈l1,l2,σ=l1+ω/1−q ...

Shift $\lambda $-Invariant Operators
Constructive Mathematical Analysis, 2019 The present note is devoted to a generalization of the notion of shift invariant operators that we call it $\lambda $-invariant operators $(\lambda \ge 0)$. Some properties of this new class are presented. By using probabilistic methods, three examples are delivered.

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

Invariant subspace problem and compact operators on non-Archimedean Banach spaces
Extracta Mathematicae, 2020 In this paper, the invariant Subspace Problem is studied for the class of non-Archimedean compact operators on an infinite-dimensional Banach space E over a nontrivial complete non-Archimedean valued field K.

Advances in Difference Equations, 2019 In the paper, we introduce a new notion of reduced linear c-shift operator Lcrf $L _{c}^{r}\,f$, and with the aid of this new operator, we study the uniqueness of meromorphic functions f(z) $f(z)$ and Lcrf $L_{c}^{r}\,f$ sharing two or more values in ...

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 ...

ρ resonance from the I = 1 ππ potential in lattice QCD
EPJ Web of Conferences, 2018 We calculate the phase shift for the I = 1 ππ scattering in 2+1 flavor lattice QCD at mπ = 410 MeV, using all-to-all propagators with the LapH smearing.
