Design and Characterization of a Dual‐Mode Soft Robotic Flapping Propeller With Pneumatic Stiffness Modulation

open access: yesAdvanced Intelligent Systems, EarlyView.
A novel soft robotic propeller overcomes traditional efficiency‐flexibility tradeoffs via a hybrid pneumatic‐cable actuation strategy. This architecture enables active stiffness modulation with dual‐mode locomotion: tunable biomimetic swimming and earthworm‐inspired wriggling for confined spaces.

Cardiac morphological and morphometric analysis of Ardea alba

open access: yesThe Anatomical Record, EarlyView.
Abstract Ardea alba (Linnaeus, 1758) is a widely distributed heron species whose cardiovascular morphology remains poorly described. This study aimed to characterize the cardiac morphology and morphometry of adult A. alba. Ten specimens were analyzed using radiographic, morphometric, histological, scanning electron microscopy, and three‐dimensional ...

Numerical and Experimental Assessment of Oxygen Distribution in a Perfusion Bioreactor to Mimic the Osteochondral Niche

open access: yesBiotechnology and Bioengineering, EarlyView.
ABSTRACT Oxygen supply is a critical parameter in 3D cell cultivation using bioreactors. Since bioreactor designs often prioritise practical constraints, understanding the oxygen supply dynamics of the media is crucial for achieving either uniform or spatially controlled oxygen delivery.

Achieving Immanent Organizational Ethics: Managing Paradoxical Tensions in Packaging

open access: yesBusiness Strategy and the Environment, EarlyView.
ABSTRACT Firms face strategic tensions in packaging materials through their conflicting but complementary social, environmental and economic goals in achieving sustainability. Reducing and repurposing plastics, glass, paper and cardboard in agriculture, horticulture and aquaculture is proving a challenge.

External Acoustic Meatus Approach for Ultrasonographic Evaluation of the Temporomandibular Joint: An Anatomical Validation and Proof‐of‐Concept Study

open access: yesClinical Anatomy, EarlyView.
ABSTRACT Temporomandibular disorders (TMD) represent a public health problem, affecting 31% of adults and the elderly and 11% of children and adolescents. Interest is growing in using ultrasound to evaluate the temporomandibular joint (TMJ). However, researchers need to standardize a reliable method.
