A Note on Rational Approximation [PDF]
Mathematics of Computation, 1960 p(x) = qo(x) * Tn +1 (x) + ro(x) YTn~l(x =-q1(x)W ro(x) + r1(x) ro(x) = q2-(X) * ri(x) + r2(x) r1() = q3(x) *r2(x) + r3(X), etc., where the (degrees of thie ri formr a strictly decreasing sequence. From these equations we may write r,(Q) = i(x) -.p(.x) + bi(x) . T.+1(x), where ai and bi are defined recursively by (a,=ai-. -qiai-?, a-1=O, a2= 1 lbi = bi-

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

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 ...

On monotone Rational Approximation
JOURNAL OF UNIVERSITY OF BABYLON for Pure and Applied Sciences, 2017 In this chapter,we focus on the shape preserving approximation using rational polynomials, for rational in _spaces, . In our work, we solve a problem raised by R. DeVore in several lectures for many years ago.

FEBS Letters, EarlyView.The process of internalization of the Shiga toxin A subunit via formation of a complex with the Shiga toxin B subunit, which specifically binds to the Gb3 receptor. The peptide is designed to act as a carrier of drugs into cancer cells. Here, we explored the potential of peptides derived from the catalytic A subunit of Shiga toxin (STxA) to be drug ...

On rational approximation in a ball in ℂN
International Journal of Mathematics and Mathematical Sciences, 2000 We study rational approximations of elements of a special class of meromorphic functions which are characterized by their holomorphic behavior near the origin in balls in ℂN by means of their rational approximants. We examine two modes of convergence for

Mathematical and Computational Applications, 2018 A complete MAPLE procedure is designed to effectively implement an algorithm for approximating trigonometric functions. The algorithm gives a piecewise polynomial approximation on an arbitrary interval, presenting a special partition that we can get its ...
