Artificial Intelligence for Engineering, EarlyView.Caputo‐based fPINNs accurately solve fractional ODEs and PDEs while exposing an accuracy–cost trade‐off driven by the history‐dependent fractional derivative. Temporal collocation and shorter time windows are the most effective strategies for improving early‐time accuracy without unnecessary spatial refinement.

An Application of Fractional Calculus to Column Theory
Mathematical and Computational ApplicationsIn this article, we employ a fractional version of the radius of curvature in Euler’s equation for column buckling, enabling us to derive a fractional differential equation in the Caputo sense.

British Journal of Management, EarlyView.Abstract This paper revisits the entrepreneurial orientation–performance relationship in family firms by examining why entrepreneurial orientation yields uneven performance returns. Drawing on entrepreneurial orientation research, upper echelons theory and gender role theory, we argue that the effectiveness of entrepreneurial orientation depends on the

On a Weighted Generalization of Iyengar Type Inequalities Involving Bounded First Derivative [PDF]
, 1999 Inequalities are obtained for weighted integrals in terms of bounds involving the first derivative of the function. Quadrature rules are obtained and the classical Iyengar inequality for the trapezoidal rule is recaptured as a special case when the ...

Interactional privilege of violence: Status and interaction in the street field
Criminology, EarlyView.Abstract Criminologists have long described and theorized the relationship between status, respect, and violence within urban communities. Although this finding is generally accepted within criminology, ethnographic empirical illustrations of this phenomenon are sparse.

On Taylor’s formulas in fractional calculus: overview and characterization for the Caputo derivative
This paper discusses some aspects of Taylor’s formulas in fractional calculus, focusing on use of Caputo’s definition. Such formulas consist of a polynomial expansion whose coefficients are values of the fractional derivative evaluated at its starting ...
