Taylor’s series and approximation to analytic functions [PDF]

open access: yesBulletin of the American Mathematical Society, 1946
Taylor's series, as the simplest expansion in terms of rational functions of an arbitrary analytic function of a complex variable, has shown itself extremely useful as a guide to other such expansions. Taylor's series itself suggests other expansions and their properties, for instance series of polynomials defined by interpolation or best approximation,

Health‐Related Social Needs in Children With Sickle Cell Disease Are Associated With Worse Health‐Related Quality of Life

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Background Children with sickle cell disease (SCD) face multiple acute and chronic medical complications that may impact their quality of life as reported by patients themselves. Health‐related social needs (HRSNs), such as food and housing insecurity, are common in people with SCD, but the association between HRSNs and patient‐reported ...

Banach Spaces of Analytic Vector-valued Functions [PDF]

open access: yes, 2007
The main theme of the thesis is the study of continuity and approximation problems, involving matrix-valued and vector-valued Hardy spaces on the unit disc ID and its boundary T in the complex plane.

Superoptimal Analytic Approximations of Matrix Functions

open access: yesJournal of Functional Analysis, 1994
The paper deals with the problem of approximation of a bounded matrix function \(G\) on the unit circle by functions \(Q\) bounded and analytic in the unit disk. In the case of continuous \(G\) it is stated that there exists a unique \(Q\) such that \(G- Q\) minimizes the singular values. The structure of the error \(G-Q\) and smoothness properties of \

The Combined Effect of Obesity and Contraceptive Use on Pulmonary Embolism in Adolescent Females Residing in the United States

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Background Combined oral contraceptive (COC) use in obese adult women dramatically increases the relative risk of developing a pulmonary embolism (PE). The risk of a PE in obese adolescent females taking contraceptives is currently unknown. The purpose of this investigation was to determine the effect of body mass index (BMI) and contraceptive

Approximation Error Bounds via Rademacher's Complexity [PDF]

open access: yes, 2008
Approximation properties of some connectionistic models, commonly used to construct approximation schemes for optimization problems with multivariable functions as admissible solutions, are investigated.

Mergelyan's approximation theorem with nonvanishing polynomials and universality of zeta-functions [PDF]

open access: yes, 2013
We prove a variant of the Mergelyan approximation theorem that allows us to approximate functions that are analytic and nonvanishing in the interior of a compact set K with connected complement, and whose interior is a Jordan domain, with nonvanishing ...

Approximation of analytic functions by shifts of zeta-functions of certain cusp forms. [PDF]

open access: yes, 2021
The approximation of analytic functions by simpler or more general functions is one of the more challenging tasks for mathematicians. This dissertation is devoted to universal functions, i.e., to functions whose shifts can approximate a wide class of ...

Central Nervous System Neuroblastoma, FOXR2‐Activated: A Pooled Analysis of Published Clinical Outcomes

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Background Central nervous system (CNS) neuroblastoma, FOXR2‐activated, is a recently recognized entity in the WHO CNS5 classification, defined by activation of the FOXR2 transcription factor and unique histopathological features. This review synthesizes available literature and pooled clinical data, providing insight into demographics ...
