Rapid grain boundary diffusion in foraminifera tests biases paleotemperature records

Anders Meibom, Jaroslaw Hubert Stolarski, Arthur Adams, Deyanira Graciela Cisneros Lazaro, Jinming Guo, Lukas Baumgartner

The paleoseawater temperature record from the oxygen isotope compositions of fossil foraminifera tests may be biased by up to about 1 degrees C due to grain-boundary diffusion alone, according to isotope exchange experiments on foraminifera tests. The oxyg ...

A modern scleractinian coral with a two-component calcite–aragonite skeleton

Anders Meibom, Jaroslaw Hubert Stolarski

One of the most conserved traits in the evolution of biomineralizing organisms is the taxon-specific selection of skeletal minerals. All modern scleractinian corals are thought to produce skeletons exclusively of the calcium-carbonate polymorph aragonite. ...

Postural Control and Consciousness and Their Applications to Lower-Limb Exoskeletons

Jemina Fasola

Human postural control requires high coordination and is distributed over the whole musculoskeletal and nervous systems. Hence, postural balance can be impaired due to various pathologies. Efficient rehabilitation programs and technological solutions are t ...

Control Strategies for Lower-limb Exoskeletons: from Full Mobilization to Assistance of Balance

Romain Pierre François Baud

Bipedal locomotion is a remarkable feature of humans. This skill is necessary for the activities of daily living. Unfortunately, many people only partially benefit from it or miss it entirely because of a disability. This may result in a slower gait, less ...

The modern analogue of a Cretaceous coral with a calcitic skeleton

Anders Meibom, Jaroslaw Hubert Stolarski

It was argued that, in contrast to all known modern scleractinian corals that form aragonite skeletons, the original mineralogy of the Cretaceous "Coelosmilia" (ca. 70-65 Ma) was calcite during a period when the Mg2+/Ca2+ ratio of the seawater was presumab ...

From the product to the process: Fine-scale skeletal structures of scleractinian corals and their relevance to biomineralization models, geochemical sampling strategies, and phylogenetic reconstructions

Anders Meibom, Jaroslaw Hubert Stolarski

Interpretation of biomineralization processes based solely on the end product - the skeleton - may seem abreakneck task. This is because the biologically controlled mineralization involves cascades of intermediatephases and the activity of a myriad of orga ...

Soft haptic device to render the sensation of flying like a drone

Dario Floreano, Carine Rognon

Haptic feedback located on the torso is proposed to enhance the state awareness of a user in virtual reality or during teleoperation while leaving the hands free for manipulation and communication. We provide haptic feedback on the torso by compressing a s ...

Wearable exoskeletons to support ambulation in people with neuromuscular diseases, design rules and control

Amalric Louis Ortlieb

Neuromuscular diseases are degenerative and, thus far, incurable disorders that lead to large muscle wasting. They result in constant deterioration of activities of daily living and in particular of ambulation. Some common types include Duchenne muscular d ...

Lean synthesis and application to lower-limb exoskeletons

Tristan Hubert Vouga

Mobility impairments are the most prevalent of all disabilities, affecting the life of nearly one in 20 individuals in developed countries. In the most severe cases, they can have dramatic consequences for the social, mental and physical well-being of thos ...

Wearable Technologies for Embodied Human-Robot Interaction

Carine Rognon

Robotic teleoperation is fundamental to augment the resilience, precision, and force of robots with the cognition of the operator. However, current interfaces, such as joysticks and remote controllers, are often complicated to handle since they require cog ...

Modular exoskeleton for example for spinal cord injured patients

Mohamed Bouri, Tristan Hubert Vouga, Paul Bertusi

The invention concerns an exoskeleton made of elements combined or attached together, said elements being adjustable or not and said elements being made in a sandwich construction. The invention also concerns a method to manufacture such an exoskeleton. ...

Modular and minimally constraining lower limb exoskeleton for enhanced mobility and balance augmentation

Mohamed Bouri, Amalric Louis Ortlieb

In one embodiment, the exoskeleton structure is fastened to the body of the user by a brace and at the foot level. The exoskeleton includes at least one set of three joints corresponding to the hip abduction/adduction, the hip flexion/extension and the kne ...

FlyJacket: An Upper Body Soft Exoskeleton for Immersive Drone Control

David Atienza Alonso, Dario Floreano, Stefano Mintchev, Fabio Isidoro Tiberio Dell'Agnola, Carine Rognon, Alexandre Thierry Cherpillod

Most human–drone interfaces, such as joysticks and remote controllers, require attention and developed skills during teleoperation. Wearable interfaces could enable a more natural and intuitive control of drones, which would make this technology accessible ...

Variable stiffness strip with strain sensing for wearable robotics

Dario Floreano, Stefano Mintchev, Jun Shintake, Vivek Ramachandran, Carine Rognon, Alice Tonazzini

Variable stiffness technologies help to solve the conflicting requirements of strength, comfort, and safety in soft exoskeletons. Here, we propose a modular variable stiffness strip based on layer jamming as a mechanical solution to constrain users' degree ...

Fine-Scale Skeletal Banding Can Distinguish Symbiotic from Asymbiotic Species among Modern and Fossil Scleractinian Corals

Anders Meibom, Jaroslaw Hubert Stolarski

Understanding the evolution of scleractinian corals on geological timescales is key to predict how modern reef ecosystems will react to changing environmental conditions in the future. Important to such efforts has been the development of several skeleton- ...

Mercury tissue residue approach in Chironomus riparius: Involvement of toxicokinetics and comparison of subcellular fractionation methods

Along with the growing body of evidence that total internal concentration is not a good indicator of toxicity, the Critical Body Residue (CBR) approach recently evolved into the Tissue Residue Approach (TRA) which considers the biologically active portion ...

The effects on biomechanics of walking and balance recovery in a novel pelvis exoskeleton during zero-torque control

Silvestro Micera

Fall-related accidents are among the most serious concerns in elderly people, amputees and subjects with neurological disorders. The aim of this paper was to investigate the behaviour of healthy subjects wearing a novel light-weight pelvis exoskeleton cont ...

Role of a polymorphism in a Hox/Pax-responsive enhancer in the evolution of the vertebrate spine

Denis Duboule

Patterning of the vertebrate skeleton requires the coordinated activity of Hox genes. In particular, Hox10 proteins are essential to set the transition from thoracic to lumbar vertebrae because of their rib-repressing activity. In snakes, however, the thor ...
