Optimal order for approximation of derivatives

Journal of Computer and System Sciences, 1979
AbstractIn this note, we show that the central difference formula for approximating f′(0) using the information {f(jh): −r ⩽j ⩽r} has maximal order of accuracy among all algorithms using this information. The technique used is an adaptation of the order-of-information approach of Wozniakowski.

“We Cannot Talk as a Family”: Complexities of Survivorship Communication Among Hispanic/Latino Young Adult Survivors of Childhood Cancer, Parents, and Clinicians

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background Young adult childhood cancer survivors (YA‐CCS) have an increased risk of treatment‐related health complications throughout their lives. Lifelong survivorship care is recommended, yet many YA‐CCS experience disruptions in care during pediatric‐to‐adult transitions and do not receive recommended survivorship care.

Realization of fractional order lowpass filter using different approximation techniques [PDF]

, 2023
Many research groups are starting to pay serious attention to the problem of fractional-order circuits. In this paper, a new approach to designing fractional order low-pass filter (FOLPF) is presented.

Approximation of continuous functions on hexagonal domains

Journal of Numerical Analysis and Approximation Theory, 2018
Some approximation properties of hexagonal Fourier series are investigated. The order of approximation by Nörlund means of hexagonal Fourier series is estimated in terms of modulus of continuity.

Adjoint Bernoulli’s Kantorovich–Schurer-Type Operators: Univariate Approximations in Functional Spaces

Mathematics
In this work, we first establish a new connection between adjoint Bernoulli’s polynomials and gamma function as a new sequence of linear positive operators denoted by Sr,ς,λ(.;.).

Forecasting the Dialysis Burden in Japan: Validation‐Based Projections of Prevalence and Incidence Through 2050

Therapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Background Japan has one of the highest dialysis prevalence rates worldwide and a shrinking, aging population. Whether dialysis burden has entered a sustained post‐peak phase or whether recent declines partly reflect pandemic‐related disruptions remains uncertain.

Estimates for Durrmeyer-type exponential sampling series in Mellin-Orlicz spaces

Demonstratio Mathematica
This study examines Durrmeyer-type exponential sampling series to obtain a quantitative estimate by using the concept of the logarithmic modulus of smoothness defined with the help of a suitable modular functional on Mellin-Orlicz spaces.

Spline-in-compression approximation of order of accuracy three (four) for second order non-linear IVPs on a graded mesh

MethodsX, 2023
A spline-in-compression method, implicit in nature, for computing numerical solution of second order nonlinear initial-value problems (IVPs) on a mesh not necessarily equidistant is discussed.

Contextual Approximation and Higher-Order Procedures [PDF]

, 2016
We investigate the complexity of deciding contextual approximation (refinement) in finitary Idealized Algol, a prototypical language combining higher-order types with state. Earlier work in the area established the borderline between decidable and undecidable cases, and focussed on the complexity of deciding approximation between terms in normal form ...

Diversity and complexity in neural organoids

FEBS Letters, EarlyView.
Neural organoid research aims to expand genetic diversity on one side and increase tissue complexity on the other. Chimeroids integrate multiple donor genomes within single organoids. Self‐organising multi‐identity organoids, exogenous cell seeding, or enforced assembly of region‐specific organoids contribute to tissue complexity.
