Kneading determinants and spectra of transfer operators in higher dimensions, the isotropic case

open access: yes, 2004
Transfer operators M_k acting on k-forms in R^n are associated to smooth transversal local diffeomorphisms and compactly supported weight functions. A formal trace is defined by summing the product of the weight and the Lefschetz sign over all fixed ...

An objective Bayesian method for including parameter uncertainty in ensemble model output statistics

open access: yesQuarterly Journal of the Royal Meteorological Society, EarlyView.
Conventional model output statistics and ensemble model output statistics methods for calibrating ensemble forecasts lead to severe underestimation of the probabilities of ensemble extremes (in blue). This is because they ignore statistical parameter uncertainty.

Ontologies for Sustainability: Theoretical Challenges

open access: yesSustainable Development, EarlyView.
ABSTRACT The lack of sustainable practices in key sectors of human societies is a global concern, posing threats for the whole planet. This paper provides the first review of ontologies for sustainability efforts, outlining their roles in assessing and advancing such efforts. Section 2 outlines three major challenges associated with sustainability: (1)

On closure operators and reflections in Goursat categories [PDF]

open access: yes, 2007
By defining a closure operator on effective equivalence relations in a regular category $C$, it is possible to establish a bijective correspondence between these closure operators and the regular epireflective subcategories $L$ of $C$.

Surface‐Engineered ZnO Nanoparticles via Acetone Immersion for Charge‐Balanced High Resolution Full‐Color Organic Light Emitting Diode Displays

open access: yesSmall, EarlyView.
Acetone post‐immersion of OLEDs effectively passivates oxygen vacancies in the ZnO electron transport layer, reducing charge trapping and enhancing electron injection. This improves hole‐blocking at the interface and decreases exciton quenching in the emission layer, resulting in significantly enhanced electrical and optical device performance ...

The History and Ideas of George Herbert Mead's Pragmatism and Its Relevance for Operational Research and Systems Thinkers

open access: yesSystems Research and Behavioral Science, EarlyView.
ABSTRACT George Herbert Mead is an oft forgotten or ignored American philosopher who was one of the originators of pragmatism. Today, he is recognised as a creative thinker who has teased out knotty problems that others in the field had not realised were problems. Understanding Mead's analysis has been made difficult because he died prematurely without

The clashing of in situ and pre‐cast technologies—Western trends and local traditions in concrete engineering shaping shell construction in 20th‐century Hungary

open access: yesStructural Concrete, EarlyView.
Abstract After a blossoming pre‐World War II (WWII) period, the concrete construction industry in then‐socialist Hungary existed in a relative isolation from the Western World during the mid‐20th century. In this paper, we focus on the body of work of one of the then newly established state‐owned design offices, IPARTERV, to show how the isolation ...

An Innovative Approach to Multi‐Valued Logic

open access: yesIEEJ Transactions on Electrical and Electronic Engineering, EarlyView.
The current generation of computer systems operates on the principles of binary logic, which encompasses both logical and arithmetic operations. However, silicon technology has reached its peak performance, prompting researchers to explore alternative methods for enhancing computational efficiency. One such method is the adoption of Multi‐Valued Logic (

Teaching Enjoyment and Vitality as Mediators of Cognitive Flexibility and Reflective Teaching in EFL Teachers: A Mixed‐Methods Serial Mediation Analysis

open access: yesTESOL Quarterly, EarlyView.
Abstract Reflective teaching (RT) is influenced by a range of cognitive, pedagogical, and psycho‐affective factors in second/foreign language (L2) education. However, empirical evidence on the influence of psycho‐affective variables on teachers' reflectivity remains limited.

William E. Walling and the Pragmatist Foundations of Proto‐Western Marxism: A Re‐Evaluation and Critique

open access: yesConstellations, EarlyView.
ABSTRACT This article reevaluates Walling as a neglected precursor to American Western Marxism, arguing that his 1912–1914 trilogy synthesized Marxist theory of his time and Deweyan pragmatism into a distinct “pragmatist conception of history.” Born into “aristocracy” yet radicalized, Walling's unique trajectory—as a co‐founder of the NAACP and critic ...
