The Nyström method for hybrid fuzzy differential equation IVPs
, 2011 In this paper, the Nyström method is developed to approximate the solutions for hybrid fuzzy differential equation initial value problems (IVPs) using the Seikkala derivative. A proof of convergence of this method is also discussed in detail.

Containing Histories Past and Present: Making Samples in the “Huntington Collection” (1893–1921)
American Anthropologist, EarlyView.ABSTRACT The Huntington Anatomical Collection (1893–1921) includes the skeletal remains of immigrants, migrants, and lifelong New York City residents. The collection's formation was coeval with the formalization of physical anthropology, and the collection was made to serve research aims centered on race and origin.

The Swedish National Pediatric Cataract Register (PECARE): Coexisting systemic disorders 2007–2023
Acta Ophthalmologica, EarlyView.Abstract Purpose To analyse the frequency and type of coexisting systemic disorders in children operated on for cataract in Sweden. Methods Data were retrieved from the Swedish National Pediatric Cataract Register (PECARE) for children operated between January 1, 2007, and December 31, 2023 (n = 975), including follow‐ups at age 1, 2, 5 and 10 ...

A fifth order phase-fitted Runge-Kutta-Nyström method for periodic initial value problems [PDF]
, 2013 A new Runge-Kutta-Nyström (RKN) method with phase-lag of order infinity for solving second order periodic initial value problems possessing oscillating solutions is derived in this paper. The derivation of phase-fitted four stage explicit RKN method with

Abstract and Applied Analysis, 2013 A new modified Runge-Kutta-Nyström method of fourth algebraic order is developed. The new modified RKN method is based on the fitting of the coefficients, due to the nullification not only of the phase lag and of the amplification error, but also of ...

Embedded Exponentially-Fitted Explicit Runge-Kutta-Nyström Methods for Solving Periodic Problems
Computation, 2020 In this work, a pair of embedded explicit exponentially-fitted Runge–Kutta–Nyström methods is formulated for solving special second-order ordinary differential equations (ODEs) with periodic solutions.
