Highly Dynamic Soft Electrohydraulic Origami Actuators for Agile and Multimodal Robotic Locomotion

open access: yesSmartBot, EarlyView.
Most current soft robots still lag far behind their natural counterparts in both agility and speed, mainly attributed to the limited morphing modes and performance of soft actuators. Here, the authors report a new methodology of electrohydraulic origami (EHO) for creating powerful and multimodal soft actuators with large strain, high speed, lightweight,

Concepts for the development of light-weight composite structures for rotor burst containment [PDF]

open access: yes, 1977
Published results on rotor burst containment with single materials, and on body armor using composite materials were used to establish a set of hypotheses about what variables might control the design of a weight-efficient protective device.

A new strategy of construction of porcine myocardial infarction model for preclinical research

open access: yesVIEW, EarlyView.
This study proposes a strategy based on the anatomical classification of the porcine left coronary artery (LCA) to establish a stable and reproducible myocardial infarction (MI) model for preclinical research. A combination of LCA classification into nine types via angiography, screening of candidate subtypes, and application of a novel embolic ...

High migratory potential of fall armyworm in West Africa despite stable temperatures and widely available year‐round habitats

open access: yesInsect Science, EarlyView.
Despite the minimal annual temperature variation and the widespread distribution of potential year‐round habitats in Ghana, the migratory potential of the local fall armyworm remains strong and is indistinguishable from that of the fall armyworm in China, which undergo seasonal migration.

Spatial Dynamics and Lifespan of Adult Cicadas After Fire and Logging: A Radiotracking Study

open access: yesIntegrative Zoology, EarlyView.
This study investigates the effects of wildfire and post‐fire salvage logging on the survival, spatial behavior, and habitat selection of Lyristes plebejus cicadas in Mediterranean pine forests. A total of 63 cicadas were captured, tagged with radio transmitters, and released in three disturbance contexts: burnt‐logged, burnt‐unlogged, and unburnt ...
