(Quasi)-uniformities on the set of bounded maps
International Journal of Mathematics and Mathematical Sciences, 1994 From real analysis it is known that if a sequence {fn, n∈ℕ} of real-valued functions defined and bounded on X⊂ℝ converges uniformly to f, then f is also bounded and the sequence {fn, n∈ℕ}. In the present paper we generalize results as the above using

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 ...

I_2-convergence of double sequences of functions [PDF]
, 2015 In this work, we discuss various kinds of ideal convergence for double sequences of functions with values in R. We introduce the concepts of I_2, I∗_2-pointwise convergence and the concepts of I_2, I∗_2-pointwise Cauchy for double sequences of functions ...

The Polynomial Pivots as Initial Values for a New Root-Finding Iterative Method
Journal of Applied Mathematics, 2015 A new iterative method for polynomial root-finding based on the development of two novel recursive functions is proposed. In addition, the concept of polynomial pivots associated with these functions is introduced.

Tumour–host interactions in Drosophila: mechanisms in the tumour micro‐ and macroenvironment
Molecular Oncology, EarlyView.This review examines how tumour–host crosstalk takes place at multiple levels of biological organisation, from local cell competition and immune crosstalk to organism‐wide metabolic and physiological collapse. Here, we integrate findings from Drosophila melanogaster studies that reveal conserved mechanisms through which tumours hijack host systems to ...

Researches in MathematicsThe paper considers the extension of analytic functions by a special family of functions — branched continued fractions. The truncation error bounds for branched continue fraction expansions of the Horn's hypergeometric functions $H_4$ and their ratios ...

Functions and Convergence [PDF]
, 2004 A piecewise continuous function f(x) defined on an interval I is bounded (or L ∞) on I if there is a number M > 0 such that |f(x)| ≤ M for all x ∊ I.

Molecular Oncology, EarlyView.Dimethyl fumarate (DMF) reduces growth of HPV‐positive cervical cancer spheroids and induces ferroptosis in cervical cancer cells via blocking SLC7A11/Glutathione (GSH) axis. Combination of subcytotoxic doses of DMF and cisplatin (CDDP) further suppresses spheroid growth and drives cell death in 2D culture models.

Weak Convergence of Robust Functions on Topological Groups
MathematicsThis paper introduces weak variants of level convergence (L-convergence) and epigraph convergence (E-convergence) for nets of level functions on general topological spaces, extending the classical metric and real-valued frameworks to ordered codomains ...
