A class of orthogonal polynomials of a new type

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 1983
The purpose of this paper is to study a class of polynomials Fnm(x,λ,ν) associated with a class of m differential equations, where λ is fixed, n is a variable parameter, m is fixed positive integer and ν is a non-negative integer

On a Problem Concerning the Weight Functions

open access: yesEuropean Journal of Combinatorics, 2002
Let \(X\) be a finite set with \(n\) elements. A function \(f: X\to\mathbb{R}\) such that \(\sum_{x\in X} f(x)\geq 0\) is called an \(n\)-weight function. \textit{N. Manickam} and \textit{N. M. Singhi} [J. Comb. Theory, Ser. A 46, 91-103 (1988; Zbl 0645.05023)] conjectured the following: if \(d\) is a positive integer and \(f\) is an \(n\)-weight ...

Social Functioning Within the First Years After Pediatric Brain Tumor Diagnosis and the Relationship With Family Psychosocial Risk

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Background Survivors of pediatric brain tumors (PBTs) can experience long‐term social difficulties, impacting quality of life. Beyond medical and environmental factors, family psychosocial risk may play a role in social outcomes by shaping the caregiving environment and may provide intervention options.

Weighted means and weighting functions

open access: yesKybernetika, 2006
Summary: We present some properties of mixture and generalized mixture operators with special stress on their monotonicity. We introduce new sufficient conditions for weighting functions to ensure the monotonicity of the corresponding operators. However, mixture operators, generalized mixture operators neither quasi-arithmetic means weighted by a ...

Retrospective Analysis of Donor Lymphocyte Infusions in Pediatric Patients With Mixed Chimerism After Hematopoietic Stem Cell Transplantation

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Background Allogeneic hematopoietic stem cell transplantation (alloHSCT) is an essential therapy for several malignant and nonmalignant diseases, but relapse and graft loss remain the principal threats to its success. Routine monitoring of chimerism and minimal residual disease (MRD) enables early detection of imminent recurrence and guides ...

The function and limit of Galileo’s falling bodies thought experiment: Absolute weight, specific weight and the medium’s resistance [PDF]

open access: yes, 2018
The ongoing epistemological debate on scientific thought experiments (TEs) revolves, in part, around the now famous Galileo’s falling bodies TE and how it could justify its conclusions.

A New Hardy–Hilbert-Type Integral Inequality Involving One Multiple Upper Limit Function and One Derivative Function of Higher Order

open access: yesAxioms, 2023
Using weight functions and parameters, as well as applying real analytic techniques, we derive a new Hardy–Hilbert-type integral inequality with the homogeneous kernel 1(x+y)λ+n involving one multiple upper limit function and one derivative function of ...

Pediatric Idiopathic Multicentric Castleman Disease Is Often Severe But Responsive to Siltuximab

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Background Idiopathic multicentric Castleman disease (iMCD) is a potentially fatal immunologic disorder marked by widespread lymphadenopathy and inflammation. Siltuximab, an interleukin‐6 (IL‐6) inhibitor, is the only FDA‐approved treatment for adult patients with iMCD.

Determination of weight function to analyze the coefficient of stress intensity and fatigue life of thick-walled tanks based on the function of displacement of cracks [PDF]

open access: yesFanāvarī-i āmūzish, 2006
Determining the stress intensity coefficient is the main parameter in reservoir design, and what in the linear failure mechanism controls the crack behavior is the value of the stress intensity coefficient. There are different ways to estimate this value.

The Impact of the COVID‐19 Pandemic on Childhood Cancer Survival: A Population‐Based Assessment of Survival Patterns Between 2015 and 2023 in Germany

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Background Numerous international studies have reported declines in new cancer diagnoses, delayed diagnoses and disruptions in cancer treatment following the implementation of COVID‐19 pandemic public health measures, raising concerns that these effects may ultimately contribute to increased cancer mortality.
