Unattainable Points in Multivariate Rational Interpolation

Journal of Approximation Theory, 1993
The problem of unattainable points is typical for the case of rational interpolation. Having computed the rational interpolant p/q from "linearized" interpolation conditions, in other words, conditions expressed for fq?p instead of f?(p/q), it may occur that an interpolation point is also a common zero of p and q and hence that the rational function p ...

Data‐Driven Printability Modeling of Hydrogels for Precise Direct Ink Writing Based on Rheological Properties

Advanced Science, EarlyView.
A predictive model for 3D printability is developed by integrating rheological analysis, including the Large Amplitude Oscillatory Shear (LAOS) test, with machine learning. With prediction errors under 10%, the model shows that post‐extrusion recovery controls horizontal printability, while high‐strain‐rate nozzle flow dictates vertical printability ...

EUPollMap: the European atlas of contemporary pollen distribution maps derived from an integrated Kriging interpolation approach [PDF]

Earth System Science Data
Modern and fossil pollen data are widely used in paleoenvironmental research to characterize past environmental changes in a given location. However, their discrete and discontinuous nature can limit the inferences that can be made from them.

Moisture Harvesting by the Structure Regulation of Hygroscopic Hydrogel for Energy and Water Sustainability

Advanced Electronic Materials, EarlyView.
Hygroscopic hydrogels are capable of utilizing the moisture from air, which can transfer the gaseous water to liquid by a surface phase transition. Taking advantage of this water, sustainable water production, thermal management, and electricity generation can be realized.

Sparse interpolation of multivariate rational functions

Theoretical Computer Science, 2011
AbstractConsider the black box interpolation of a τ-sparse, n-variate rational function f, where τ is the maximum number of terms in either numerator or denominator. When numerator and denominator are at most of degree d, then the number of possible terms in f is O(dn) and explodes exponentially as the number of variables increases.

Enhancing Solid Oxide Fuel Cells Development through Bayesian Active Learning

Advanced Energy Materials, EarlyView.
This article presents an active learning approach using Bayesian optimization to calibrate the multiphase‐field model parameters for simulating the aging of Ni‐GDC anodes in SOFCs. By integrating experimental data and navigating through complex parameter spaces, it enhances predictive accuracy and provides insights into microstructural evolution ...

Multivariable Nehari problem and interpolation

Journal of Functional Analysis, 2003
AbstractIn this paper we obtain a multivariable Nehari type theorem for Hankel operators, extending the classical result as well as Treil–Volberg generalization. The result is based on a new generalization of the noncommutative commutant lifting theorem which extends to several variables the commutant lifting result obtained by Treil and Volberg, and ...

From Operando Investigations to Implementation of Ni‐MOF‐74 Oxygen Evolution Electrocatalysts

Advanced Energy Materials, EarlyView.
This work shows how understanding the transformations of Ni‐MOF‐74 during oxygen evolution reaction via operando characterizations leads to the development of a novel, amorphous Ni metal organic compound (Ni‐MOC*), which achieves high current densities both in a three‐electrode cell and in an anion exchange membrane water electrolyzer (AEM‐WE) with a ...
