Resonance phenomenon of the ATP motor as an ultrasensitive biosensor
Biochemical and Biophysical Research Communications, 2012We designed a rotary biosensor as a damping effector, with the rotation of the F(0)F(1)-ATPase driven by Adenosine Triphosphate (ATP) synthesis being indicated by the fluorescence intensity and a damping effect force being induced by the binding of an RNA molecule to its probe on the rotary biosensor.

Grasping the pain: Motor resonance with dangerous affordances
Consciousness and Cognition, 2012Two experiments, one on school-aged children and one on adults, explored the mechanisms underlying responses to an image prime (hand vs. control object) followed by graspable objects that were, in certain cases, dangerous. Participants were presented with different primes (a male, a female and a robotic grasping-hand; a male and a female static-hand; a

Magnetic resonance imaging in motor neuron disease
Journal of Neurology, 1990Magnetic resonance imaging (MRI) of the brain was evaluated in 20 patients with motor neuron disease (MND) and in a control group of 11 healthy people. Bilateral increased signal areas of various sizes in the centrum semiovale, corona radiata, internal capsule, pedunculi of midbrain, pons, medulla and even in the frontal lobe, topographically related ...

The Neurophysiology of Early Motor Resonance
2008The discovery of mirror neurons in the monkey brain and the subsequent description of a mirror neuron system (MNS) in humans have triggered unprecedented interest in the neural basis of social cognition. Although the mechanism matching action observation and execution is now well documented in human adults, much remains to be learned about its normal ...

Quantum features of Brownian motors and stochastic resonance
Chaos: An Interdisciplinary Journal of Nonlinear Science, 1998We investigate quantum Brownian motion sustained transport in both, adiabatically rocked ratchet systems and quantum stochastic resonance (QSR). Above a characteristic crossover temperature T0 tunneling events are rare; yet they can considerably enhance the quantum-noise-driven particle current and the amplification of signal output in comparison to ...

Motor resonance mechanisms are preserved in Alzheimer’s disease patients
Neuroscience, 2012This study aimed to better characterize the sensorimotor mechanisms underlying motor resonance, namely the relationship between motion perception and movement production in patients suffering from Alzheimer's disease (AD). This work first gives a kinematic description of AD patients' upper limb movements, then it presents a simple paradigm in which a ...

Förster resonance energy transfer and kinesin motor proteins
Chem. Soc. Rev., 2014Förster Resonance Energy Transfer (FRET) is the phenomenon of non-radiative transfer of electronic excitations from a donor fluorophore to an acceptor, mediated by electronic dipole-dipole coupling. The transfer rate and, as a consequence, efficiency depend non-linearly on the distance between the donor and the acceptor.

Resonant booster for driving ultrasonic motors
IEEE 34th Annual Conference on Power Electronics Specialist, 2003. PESC '03., 2003Ultrasonic motors have attracted considerable attention as a new type of actuator in servo-system and the on-off controlling field, but the widely-use of USMs are limited by the control circuits with transformers. Accompanying with the equivalent circuit of the ultrasonic motors, this paper has established a driving circuit using the resonant booster ...

Design and construction of a resonant magnetostrictive motor
IEEE Transactions on Magnetics, 1996A resonant magnetostrictive motor was built and tested. Its stator modules are made of a ring and two Terfenol-D linear actuators. Two resonant modes of the modules (a translation mode and a flexure mode) are coupled in order to produce elliptical vibrations which are used to transmit motion to two rotors by friction.

Motor resonance to affective touch
Assessment of Motor Evoked Potentials (MEPs) during observation of interpersonal touch. The anonymized data repository file contains demographic information, raw MEPs at baseline, Z-Standardized MEPs for each condtiion (i.e., Muscle: ECR vs FDI, body site: palm vs hand, velocity: static vs slow vs fast), the PTA indexes for FDI and ECR, scores at the ...Urgesi, Cosimo +2 more
