Recurrence relations of the multi-indexed orthogonal polynomials. III
, 2018 In Paper II, we presented conjectures of the recurrence relations with constant coefficients for the multi-indexed orthogonal polynomials of Laguerre, Jacobi, Wilson, and Askey-Wilson types.

Humans are not unique: difficult birth is common in placental mammals
Biological Reviews, EarlyView.ABSTRACT Human childbirth is widely presumed to be uniquely difficult and dangerous compared to birth in other mammals. Tight fetopelvic proportions can result in obstructed labour and contribute to high rates of maternal and neonatal mortality. Ideas summarised under the ‘obstetrical dilemma’ have contributed to this assumption by explaining difficult

Advances in causal discovery methods for ecological time series
Biological Reviews, EarlyView.ABSTRACT Recent advances in data collection technologies (e.g. automated sensor networks, satellite remote sensing, and high‐throughput sequencing) have greatly expanded the availability of ecological time series, enabling new opportunities for causal analyses in dynamic ecosystems.

A Business Framework for Product Take‐Back—A Structured Multiple‐Case Analysis
Business Strategy and the Environment, EarlyView.ABSTRACT The potential of take‐back systems remains largely unrealized as initiatives have proven difficult to implement in practice. The question is why we do not see more take‐back systems given the substantial environmental benefits. We try to understand the challenges and stumbling blocks in setting up take‐back from a business perspective.

Several Characterizations of the Generalized 1-Parameter 3-Variable Hermite Polynomials
MathematicsThis paper presents a novel framework for introducing generalized 1-parameter 3-variable Hermite polynomials. These polynomials are characterized through generating functions and series definitions, elucidating their fundamental properties.

Stability of Matrix Recurrence Relations
Motivated by the rich properties and various applications of recurrence relations, we consider the extension of traditional recurrence relations to matrices, where we use matrix multiplication and the Kronecker product to construct matrix sequences.

Business Strategy and the Environment, EarlyView.ABSTRACT Rapid technological change, shorter lifecycles and rising demand for electrical and electronic equipment (EEE) are increasing waste electrical and electronic equipment (WEEE) and emphasise the need for a circular economy. This paper identifies barriers and enablers of the circular transition in EEE and outlines interventions.

Business Strategy and the Environment, EarlyView.ABSTRACT In response to growing global challenges, this study explores how social entrepreneurship within the Edible City movement contributes to building resilient, sustainable, and equitable urban food systems. Drawing on semistructured interviews with over 70 stakeholders across five cities—Berlin, Andernach, Oslo, Rotterdam, and Havana—we ...

On a New Generalization of Pell Hybrid Numbers
Annales Mathematicae SilesianaeIn this paper, we define and study a new one-parameter generalization of the Pell hybrid numbers. Based on the definition of r-Pell numbers, we define the r-Pell hybrid numbers.
