Patterns of spinal motion, kinematic spaces and the land‐to‐sea transition in carnivorans

The Anatomical Record, EarlyView.
Using 3D reconstructions, we quantify intervertebral joint mobility to investigate how cervical, thoracic, and lumbar vertebral regions evolved distinct kinematic roles in pinnipeds. The findings reveal lineage‐specific adaptations for swimming and highlight the functional significance of vertebral joint flexibility in ecological transitions.

A compatibility criterion for optimal control and information aggregation in hierarchical network systems

Asian Journal of Control, EarlyView.
Abstract Large swarms often adopt a hierarchical network structure that incorporates information aggregation. Although this approach offers significant advantages in terms of communication efficiency and computational complexity, it can also lead to degradation due to information constraints.

Modeling and parameter estimation for fractional large‐scale interconnected Hammerstein systems

Asian Journal of Control, EarlyView.
Abstract This paper addresses the challenge of modeling and identifying large‐scale interconnected systems exhibiting memory effects, hereditary properties, and non‐local interactions. We propose a fractional‐order extension of the Hammerstein architecture that incorporates Grünwald–Letnikov operators to capture complex dynamics through multiple ...

Sustainability Performance, Cost of Debt, and Institutional Environment Quality: Global Evidence From the Hospitality and Tourism Industry

Business Strategy and the Environment, EarlyView.
ABSTRACT This study examines how sustainability performance affects the cost of debt financing in the hospitality and tourism industry and whether institutional environment quality moderates this relationship. Using a dataset of 2302 firm‐year observations from 34 countries between 2010 and 2022, the results show that sustainability performance is ...
