From Biological Fractal Dynamics to Analog Fractional‐Order Circuits: A System Design Framework Based on Operatorization Thought

International Journal of Mechanical System Dynamics, EarlyView.
ABSTRACT Fractional calculus, with its unique advantage in describing memory and nonlocal effects, has become a key tool for modeling nonlinear dynamic systems. Its integration with circuit systems has opened up a new paradigm for modern circuit design.

Exploring the Role of Special Events in Relationship Fundraising

Nonprofit Management and Leadership, EarlyView.
ABSTRACT The relationship fundraising paradigm conceptualizes charitable giving as an outcome of ongoing interpersonal engagement between donors and organizations, often depicted in practice as a cyclical process with multiple phases. This study examines how special events—a widely used but understudied relationship fundraising tool—factor into this ...

Convergence of Low‐Fertility Policies Beyond Policy Transfer: A Comparative Analysis of Korea and Hungary

Public Administration and Development, EarlyView.
ABSTRACT This study compares policy responses to persistent low fertility in Korea and Hungary, two countries facing similar demographic pressures but embedded in distinct institutional settings. It asks whether the diffusion of pronatalist policies has produced convergence in the design, implementation, and effects of fertility policy in these cases ...

Sliding Motions on Non‐Euclidean State Spaces: A Differential‐Geometric Perspective

International Journal of Robust and Nonlinear Control, EarlyView.
ABSTRACT This paper extends sliding‐mode control theory to nonlinear systems evolving on smooth manifolds. Building on differential geometric methods, we reformulate Filippov's notion of solutions, characterize well‐defined vector fields on quotient spaces, and provide a consistent geometric definition of higher‐order sliding modes.

Unveiling the Impact of Digitized Supply Chains on Reducing Food Loss and Waste: A Multiple Case Study of Italian Agri‐Food Firms

Sustainable Development, EarlyView.
ABSTRACT Food loss and waste (FLW) within agri‐food supply chains significantly impact the consumer economy, depleting natural resources and contributing to greenhouse gas emissions, thereby posing a critical challenge to sustainable development. Digital transformation is increasingly recognised as a key lever for reducing FLW in agri‐food supply ...
