A Family of Three-Point Methods of Ostrowski's Type for Solving Nonlinear Equations

Journal of Applied Mathematics, 2012
A class of three-point methods for solving nonlinear equations of eighth order is constructed. These methods are developed by combining two-point Ostrowski's fourth-order methods and a modified Newton's method in the third step, obtained by a suitable ...

Lost in Aggregation: Quantifying Measurement Error from Geographic Centroids

Economic Record, EarlyView.
Due to privacy laws and regulations, microdata typically provide regional identifiers rather than exact coordinates. Researchers therefore often construct spatial variables from these aggregations, but the statistical implications depend on the research setting.

Computational issues of hybrid and multipoint mixed methods for groundwater flow in anisotropic media

, 2010
International audienceLowest-order Raviart–Thomas and Brezzi–Douglas–Marini mixed methods are considered for groundwater flow simulations. Typically, mixed methods lead to a saddle-point problem, which is expensive to solve.

Dystrophia Smolandiensis is characterized by a novel NQO1 variant and a distinct phenotype from COL17A1‐associated epithelial recurrent erosion dystrophy

Acta Ophthalmologica, EarlyView.
Abstract Purpose To determine the molecular cause of the two epithelial recurrent erosion dystrophies, Dystrophia Smolandiensis and Dystrophia Helsinglandica, and to identify phenotypic differences between the two conditions. Methods DNA samples and clinical data from structured interview records were obtained from the Swedish families in which ...

Timing the Sacred: A Multi‐Step Chronological Framework for the Llullaillaco Inca Burial

Archaeometry, EarlyView.
ABSTRACT Absolute radiocarbon dating offers high precision, but its application to historical contexts, such as the Inca civilization, requires a rigorous methodological approach. This research examines methods to enhance chronological accuracy through a case study of artifacts from the Llullaillaco Capacocha sacrifice.

Solvability of multipoint differential operators of first order

Electronic Journal of Differential Equations, 2015
Based on methods of operator theory, we describe all boundedly solvable extensions of the minimal operator generated by a linear multipoint functional differential-operator expression of first order, in a direct sum of Hilbert space of vector ...

Comparative Analysis of Three Vertebral Screw Placement Directions in Anterior Thoracolumbar Fracture Surgery: A Finite Element Study

Orthopaedic Surgery, Volume 17, Issue 5, Page 1464-1477, May 2025.
This study compares the biomechanical effects of three anterior fixation systems in thoracolumbar surgery—HXTL, NHXTL, and Medtronic's CD Horizon ANTERIOR. Finite element analysis evaluates stress and displacement across vertebral bodies and support structures under varying load conditions. Results indicate the HXTL system minimizes nail–rod stress yet

Composition‐Tunable Lignocellulosic Aerogels From Eucalyptus spp. Bark for Oil and Cu2+ Adsorption

Journal of Applied Polymer Science, Volume 143, Issue 43, November 15, 2026.
Composition‐tunable lignocellulosic aerogels are produced from Eucalyptus spp. bark by combining cellulose, lignin, and microfibrillated cellulose without post‐synthetic functionalization. The resulting porous architectures show contaminant‐dependent performance: CEL favors cooking‐oil uptake, CEL‐M favors pump‐oil uptake, and CEL‐L‐M provides the ...
