Time to Diagnosis Among Children and Adolescents With Cancer in Québec, Canada: A Population‐Based Study

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background Timely cancer diagnosis in children and adolescents is important to improving outcomes. We aimed to quantify time to diagnosis and assess variations by patient, demographic and system‐level factors. Procedure We conducted a population‐based study of individuals aged 0–19 years diagnosed with one of 12 cancers from 2010 to 2022 in ...

Approximation of conic sections by weighted Lupaş post-quantum Bézier curves

Demonstratio Mathematica, 2022
This paper deals with weighted Lupaş post-quantum Bernstein blending functions and Bézier curves constructed with the help of bases via (p,q)\left(p,q)-integers. These blending functions form normalized totally positive bases.

Effectiveness of Resistance Intradialytic Exercise Compared to Aerobic Intradialytic Exercise for Patients With Chronic Kidney Disease: A Randomized Controlled Clinical Trial

Therapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Background Patients with chronic kidney disease undergoing hemodialysis commonly experience reduced physical function, fatigue, poor sleep quality, and impaired health‐related quality of life. Intradialytic exercise has been proposed as a non‐pharmacological strategy to improve these outcomes.

Approximation by rational functions in Morrey-Smirnov classes

Kuwait Journal of Science, 2018
In this article, we investigate the direct problem of approximation theory in Morrey-Smirnov classes of analytic functions, defined on a doubly-connected domain bounded by two sufficiently smooth curves.

Design of Multi-Dimensional Recursive Systems through Pad'e Type Rational Approximation

Nonlinear Analysis, 2002
The results obtained in classical 1-D rational approximation are extended in this paper to rational approximation of M-D functions. A full analog of classical Montessus de Ballore theorem for the convergence of the rows of Pad´e’s tables is obtained.

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 Analytical Extension of Generalized Hypergeometric Function ₃F₂

Axioms
The paper considers the generalized hypergeometric function F23, which is important in various fields of mathematics, physics, and economics. The method is used, according to which the domains of the analytical continuation of the special functions are ...

Orthogonal rational functions and modified approximants [PDF]

Numerical Algorithms, 1996
This paper studies certain rational approximants to the function \[ F_\mu(z)= \int^\pi_{- \pi} {t+ z\over t- z} d\mu(\theta),\quad(t= e^{i\theta}), \] where \(\mu\) is a positive Borel measure on the unit circle in the complex plane. These approximants are constructed in terms of orthogonal rational functions with fixed poles. In fact, given a sequence

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 the Domain of Analytical Continuation of the Ratios of Generalized Hypergeometric Functions ₃F₂

Axioms
The paper considers the problem of the analytical extension of the ratios of generalized hypergeometric functions F23 A new domain of analytic continuation for these ratios under certain conditions to parameters is established.
