Mate choice and the operational sex ratio: an experimental test with robotic crabs.

Journal of evolutionary biology
The operational sex ratio (OSR: sexually active males: receptive females) predicts the intensity of competition for mates. It is less clear, however, under what circumstances, the OSR predicts the strength of sexual selection - that is, the extent to...

Biomimetic Active Touch with Fingertips and Whiskers.

IEEE transactions on haptics
This study provides a synthetic viewpoint that compares, contrasts, and draws commonalities for biomimetic perception over a range of tactile sensors and tactile stimuli. Biomimetic active perception is formulated from three principles: (i) evidence ...

Design of a Coupled Thermoresponsive Hydrogel and Robotic System for Postinfarct Biomaterial Injection Therapy.

The Annals of thoracic surgery
BACKGROUND: In preclinical testing, ventricular wall injection of hydrogels has been shown to be effective in modulating ventricular remodeling and preserving cardiac function. For some approaches, early-stage clinical trials are under way. The hydro...

Turtle mimetic soft robot with two swimming gaits.

Bioinspiration & biomimetics
This paper presents a biomimetic turtle flipper actuator consisting of a shape memory alloy composite structure for implementation in a turtle-inspired autonomous underwater vehicle. Based on the analysis of the Chelonia mydas, the flipper actuator w...

Bio-inspired flexible joints with passive feathering for robotic fish pectoral fins.

Bioinspiration & biomimetics
In this paper a novel flexible joint is proposed for robotic fish pectoral fins, which enables a swimming behavior emulating the fin motions of many aquatic animals. In particular, the pectoral fin operates primarily in the rowing mode, while undergo...

Artificial Metamorphosis: Evolutionary Design of Transforming, Soft-Bodied Robots.

Artificial life
We show how the concept of metamorphosis, together with a biologically inspired model of multicellular development, can be used to evolve soft-bodied robots that are adapted to two very different tasks, such as being able to move in an aquatic and in...

Modelling the presence and identifying the determinant factors of dominant macroinvertebrate taxa in a karst river.

Environmental monitoring and assessment
Modelling the macroinvertebrate community is important for evaluating the status of aquatic ecosystem health. Alternative to physical-based approaches, this study proposed two data-driven methods, support vector machine (SVM) and artificial neural ne...

Automatic Recognition of Aggressive Behavior in Pigs Using a Kinect Depth Sensor.

Sensors (Basel, Switzerland)
Aggression among pigs adversely affects economic returns and animal welfare in intensive pigsties. In this study, we developed a non-invasive, inexpensive, automatic monitoring prototype system that uses a Kinect depth sensor to recognize aggressive ...

APPAGATO: an APproximate PArallel and stochastic GrAph querying TOol for biological networks.

Bioinformatics (Oxford, England)
MOTIVATION: Biological network querying is a problem requiring a considerable computational effort to be solved. Given a target and a query network, it aims to find occurrences of the query in the target by considering topological and node similariti...

The Ontology for Biomedical Investigations.

PloS one
The Ontology for Biomedical Investigations (OBI) is an ontology that provides terms with precisely defined meanings to describe all aspects of how investigations in the biological and medical domains are conducted. OBI re-uses ontologies that provide...
