Physiological modules for generating discrete and rhythmic movements: Component analysis of EMG signals
(Frontiers Research Foundation, 2015-01-09)
A central question in Neuroscience is that of how the nervous system generates the spatiotemporal commands needed to realize complex gestures, such as handwriting. A key postulate is that the central nervous system (CNS) ...
Digital Quantum Rabi and Dicke Models in Superconducting Circuits
(Nature Publishing Group, 2014-12-15)
We propose the analog-digital quantum simulation of the quantum Rabi and Dicke models using circuit quantum electrodynamics (QED). We find that all physical regimes, in particular those which are impossible to realize in ...
Self-Organized Criticality, Plasticity and Sensorimotor Coupling. Explorations with a Neurorobotic Model in a Behavioural Preference Task
(Public Library of Science, 2015-02-23)
During the last two decades, analysis of 1/f noise in cognitive science has led to a considerable progress in the way we understand the organization of our mental life. However, there is still a lack of specific models ...
The Forbidden Quantum Adder
(Nature Publishing Group, 2015-07-08)
Quantum information provides fundamentally different computational resources than classical information. We prove that there is no unitary protocol able to add unknown quantum states belonging to different Hilbert spaces. ...
Empirical Doppler Characterization of Signals Scattered by Wind Turbines in the UHF Band under Near Field Condition
(Hindawi Publishing Corporation, 2013)
Time variability of the scattering signals from wind turbines may lead to degradation problems on the communication systems provided in the UHF band, especially under near field condition. In order to analyze the variability ...
Dealing with Energy-QoE Trade-Offs in Mobile Video
(Hindawi Publishing Corporation, 2013)
Scalable video coding allows an efficient provision of video services at different quality levels with different energy demands. According to the specific type of service and network scenario, end users and/or operators ...
Efficient Gate-tunable light-emitting device made of defective boron nitride nanotubes: from ultraviolet to the visible
(Nature Publishing Group, 2013-09)
Boron nitride is a promising material for nanotechnology applications due to its two-dimensional graphene-like, insulating, and highly-resistant structure. Recently it has received a lot of attention as a substrate to grow ...
Long-lived oscillatory incoherent electron dynamics in molecules: trans-polyacetylene oligomers
(IOP Publishing, 2013-04)
We identify an intriguing feature of the electron-vibrational dynamics of molecular systems via a computational examination of trans-polyacetylene oligomers. Here, via the vibronic interactions, the decay of an electron ...
Ab initio molecular dynamics on the electronic Boltzmann equilibrium distribution
(IOP Publishing, 2010-08-31)
We prove that for a combined system of classical and quantum particles, it is possible to describe a dynamics for the classical particles that incorporates in a natural way the Boltzmann equilibrium population for the ...
Video Quality Prediction Models Based on Video Content Dynamics for H.264 Video over UMTS Networks
(Hindawi Publishing Corporation, 2010)
The aim of this paper is to present video quality prediction models for objective non-intrusive, prediction of H.264 encoded video for all content types combining parameters both in the physical and application layer over ...
