Published in 2018 at "Advanced Functional Materials"

DOI: 10.1002/adfm.201803712

Abstract: Perovskite-structured (ABO(3)) transition metal oxides are promising bifunctional electrocatalysts for efficient oxygen evolution reaction (OER) and oxygen reduction reaction (ORR). In this paper, a set of epitaxial rare-earth nickelates (RNiO3) thin films is investigated with… read more here.

Published in 2025 at "Ecology and Evolution"

DOI: 10.1002/ece3.71020

Abstract: ABSTRACT Understanding the drivers influencing ungulate population dynamics is crucial for developing conservation and management strategies to support wildlife health. Trace and macro elements are vital for ungulate growth, reproduction and survival. Thus, the trajectory… read more here.

Published in 2025 at "Journal of the Experimental Analysis of Behavior"

DOI: 10.1002/jeab.70060

Abstract: When responding to a stimulus exerting overselective control over behavior is extinguished, control by underselected stimuli may emerge. We investigated how the degree of extinction influences control by underselected stimuli. Adult humans (N = 459) chose between… read more here.

Published in 2023 at "Journal of the experimental analysis of behavior"

DOI: 10.1002/jeab.850

Abstract: Stimulus overselectivity describes strong control by one stimulus element at the expense of other equally relevant elements. Research suggests that control by underselected stimuli emerges following extinction of the overselected stimulus ("revaluation") and the emergence… read more here.

Published in 2017 at "Mathematical Methods in The Applied Sciences"

DOI: 10.1002/mma.4641

Abstract: In this article, a finite element scheme based on the Newton's method is proposed to approximate the solution of a nonlocal coupled system of parabolic problem. The Crank-Nicolson method is used for time discretization. Well-posedness… read more here.

Published in 2023 at "Microwave and Optical Technology Letters"

DOI: 10.1002/mop.33696

Abstract: Rigorously accounting for mutual coupling effects in antenna array synthesis, generally requires that embedded element patterns (EEPs) be determined. The method of moments (MoM) is typically used. Multiple linear system solutions are required, corresponding to… read more here.

Published in 2024 at "Microwave and Optical Technology Letters"

DOI: 10.1002/mop.34216

Abstract: A broadband single‐layer reflectarray comprising three‐layer concentric split ring elements is proposed. The reflection phase is achieved by changing the flare angle of the inner and outer split rings. The resonance of the element is… read more here.

Published in 2017 at "International Journal for Numerical Methods in Engineering"

DOI: 10.1002/nme.5290

Abstract: Summary A new nonconforming brick element is introduced, which only has 13 DOFs locally and takes P2⊕Span{x13,x23,x33} as its shape functions space. The vector-valued version generates, together with a discontinuous P1 approximation, an inf-sup stable… read more here.
