Osteoarthritis is a common cartilage disease, particularly in societies with aging population. Over 80% of the people over 75 years are affected in the USA. MRI and X-ray can be used to image cartilage, but both approaches suffer from specific drawbacks. X-ray Talbot-Lau interferometers (TLI) have the potential to unite benefits from both modalities. However, TLI setups require to be carefully designed...
The search for higher efficiencies in photovoltaics has led us to develop increasingly complex solar cell architectures that rely on increasingly complex physical processes. The desire to overcome the Shockley-Queisser efficiency limit has caused us to consider stacks of junctions with cascading bandgaps, quantum dots and impurities for the creation of intermediate bands, amongst others. The need...
This study focuses on biomimetic sensory motor control of a robotic arm. We have developed a command circuit that was mathematically deduced from physical and mathematical constraints describing the function of cerebellar pathways. The control circuit contains an internal predictive model of the direct biomechanical function of the limb placed in a closed loop, so that the circuit computes an approximate...
