Taylor Polynomials of Rational Functions

Acta Mathematica Vietnamica, 2023
A Taylor variety consists of all fixed order Taylor polynomials of rational functions, where the number of variables and degrees of numerators and denominators are fixed. In one variable, Taylor varieties are given by rank constraints on Hankel matrices. Inversion of the natural parametrization is known as Padé approximation. We study the dimension and

Association Between Dinutuximab Beta Exposure and Post‐End‐of‐Treatment Survival in Neuroblastoma: A Weighted Patient‐Level Analysis of Three Clinical Studies

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Objectives The association between exposure to dinutuximab beta (DB) and event‐free survival (EFS) or overall survival (OS) of neuroblastoma patients was assessed using data collected during three clinical trials (five cohorts). Methods A systematic review (March 2026) was conducted to identify relevant studies (prospective; registered DB ...

The integral of 2- refined rational neutrosophic functions [PDF]

Neutrosophic Sets and Systems
The main objective of this paper is to study the integral of 2- refined rational neutrosophic functions, by providing direct rules that make it easy for us to find the integral of 2- refined rational neutrosophic functions, where the division of refined ...

Hilbert’s 17th problem in free skew fields

Forum of Mathematics, Sigma, 2020
This paper solves the rational noncommutative analogue of Hilbert’s 17th problem: if a noncommutative rational function is positive semidefinite on all tuples of Hermitian matrices in its domain, then it is a sum of Hermitian squares of noncommutative ...

Counting with rational functions

Theoretical Computer Science, 1986
The authors characterize a special class of rational functions from a free monoid \(A^*\) into a cyclic free monoid \(t^*\). A semaphore is a subset H of \(A^*\) such that no word in H is a (connected) factor of another word in H. A partial function \(\alpha\) : \(A^*\to t^*\) is called a counting function if there exist \(n\geq 1\), rational ...

Childhood Acute Lymphoblastic Leukemia Survival in Western Kenya: Reduction in Early Deaths and Treatment Abandonment

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background An earlier study on children diagnosed with acute lymphoblastic leukemia (ALL) at Moi Teaching and Referral Hospital (MTRH) in Kenya reported a low event‐free survival (EFS), excess treatment abandonment, and high induction mortality.

Characterizing Polynomial Time Computability of Rational and Real Functions [PDF]

Electronic Proceedings in Theoretical Computer Science, 2009
Recursive analysis was introduced by A. Turing [1936], A. Grzegorczyk [1955], and D. Lacombe [1955]. It is based on a discrete mechanical framework that can be used to model computation over the real numbers.

Integrate inequalities for the higher derivatives of Blashke product

Журнал Белорусского государственного университета: Математика, информатика, 2018
Upper and lower inequalities for the higher derivatives of Blashke product in the Lebesgue space Lp are obtained in this work. All p ∈ (0; +∞)\ {1/s}, s ∈ N\1, are considered, where s is order of the derivative.
