We present a new surface energy potential for the segmentation of cylindrical objects in 3D medical imaging using parametric spline active contours (a.k.a. spline-snakes). Our energy formulation is based on an optimal steerable surface detector. Thus, we c ...

Tissue loss significantly reduces the potential for functional recovery after spinal cord injury. We previously showed that implantation of porous scaffolds composed of a biodegradable and biocompatible block copolymer of Poly-lactic-co-glycolic acid and P ...

Challenges in visual and inertial information gathering for a sprawling posture robot

Auke Ijspeert, Kamilo Andres Melo Becerra, Tomislav Horvat, Mahsa Parsapour

We discuss challenges a sprawling posture legged robot faces when moving in a complex environment. These kind of robots can be used for search and rescue applications when proper sensors are used and placed correctly. Finding an adequate position for placi ...

The Human Central Pattern Generator for Locomotion: Does It Exist and Contribute to Walking?

Auke Ijspeert, Florin Dzeladini, Karen Minassian

The ability of dedicated spinal circuits, referred to as central pattern generators (CPGs), to produce the basic rhythm and neural activation patterns underlying locomotion can be demonstrated under specific experimental conditions in reduced animal prepar ...

Stability Requirements of Deep Steel Wide-Flange Columns under Cyclic Loading

Dimitrios Lignos, Ahmed Mohamed Ahmed Elkady

Just recently, valuable experimental data that characterized the hysteretic behavior of deep wide-flange steel columns (i.e., column depth, d >16 inches) at full-scale became available. Such members are typically used in steel moment-resisting frames (MRFs ...

Surgical probe and implant development for nucleus pulposus replacements

Andreas Schmocker

Intervertebral disc degeneration is a major reason why we experience low back pain. Intervertebral discs are located in-between the vertebrae of the spine. They act, among other, as shock absorbers by distributing the mechanical load applied to the spine w ...

Tetrapod axial evolution and developmental constraints; Empirical underpinning by a mouse model

Denis Duboule

The tetrapod vertebral column has become increasingly complex during evolution as an adaptation to a terrestrial life. At the same time, the evolution of the vertebral formula became subject to developmental constraints acting on the size of the cervical a ...

Potential Mechanisms Leading to Overuse Injuries of the Back in Alpine Ski Racing - A Descriptive Biomechanical Study

Benedikt Fasel

Background: Overuse injuries of the back are a common complaint among top athletes and of competitive alpine skiers in particular. However, there is limited understanding about the sport-specific causes of these injuries that is essential for their prevent ...

Dorsal root ganglia (DRG) neurons, located in the intervertebral foramina of the spinal column, can be used to create an in vitro system facilitating the study of nerve regeneration and myelination. The glial cells of the peripheral nervous system, Schwann ...

Cheetah-cub-S: Steering of a Quadruped Robot using Trunk Motion

Auke Ijspeert, Peter Eckert, Karl Weinmeister

A reliable concept for steering was realized by in- tegrating a spine-like structure with one DoF into a quadruped robot - Cheetah-cub-S. We increased maneuverability dramat- ically compared to a robot with rigid spine, while keeping controlling effort low ...
