Heisenberg uncertainty principle as a probe of entanglement entropy: Application to superradiant quantum phase transitions

Quantum phase transitions are often embodied by the critical behavior of purely quantum quantities such as entanglement or quantum fluctuations. In critical regions, we underline a general scaling relation between the entanglement entropy and one of the mo ...

3D structuration of LTCC and related technologies for thermal management and microfluidic structures

Peter Ryser, Thomas Maeder, Caroline Jacq, Bo Jiang, Fabrizio Vecchio, Conor Joseph Slater

Ceramic technologies such as LTCC (Low Temperature Co-fired Ceramic) and thick-film are used widely in electronic circuits exposed to harsh environments, for applications in fields such as aerospace, automotive and energy exploration, where, owing to their ...

Causal models as multiple working hypotheses about environmental processes

The environmental modeller faces a dilemma. Science often demands that more and more process representations are incorporated into models (particularly to avoid the possibility of making missing process errors in predicting future response). Testing the ca ...

Significance Driven Computation on Next-Generation Unreliable Platforms

Vaibhav Gupta, Georgios Karakonstantis

In this paper, we propose a design paradigm for energy efficient and variation-aware operation of next-generation multicore heterogeneous platforms. The main idea behind the proposed approach lies on the observation that not all operations are equally impo ...

Inhibitory Plasticity Balances Excitation and Inhibition in Sensory Pathways and Memory Networks

Wulfram Gerstner, Friedemann Zenke, Claudia Clopath, Tim Vogels

Cortical neurons receive balanced excitatory and inhibitory synaptic currents. Such a balance could be established and maintained in an experience-dependent manner by synaptic plasticity at inhibitory synapses. We show that this mechanism provides an expla ...

Brain dynamics underlying training-induced improvement in suppressing inappropriate action

Fosco Bernasconi

Inhibitory control, a core component of executive functions, refers to our ability to suppress intended or ongoing cognitive or motor processes. Mostly based on Go/NoGo paradigms, a considerable amount of literature reports that inhibitory control of respo ...

Double nerve intraneural interface implant on a human amputee for robotic hand control

Silvestro Micera, Stanisa Raspopovic, Jacopo Rigosa

Objectives: The principle underlying this project is that, despite nervous reorganization following upper limb amputation, original pathways and CNS relays partially maintain their function and can be exploited for interfacing prostheses. ...

Deviant trajectories of cortical maturation in 22q11.2 deletion syndrome (22q11DS): A cross-sectional and longitudinal study

Jean-Philippe Thiran, Meritxell Bach Cuadra, Marie Schaer

22q11.2 deletion syndrome (22q11DS) is associated with an increased susceptibility to develop schizophrenia. Despite a large body of literature documenting abnormal brain structure in 22q11DS, cerebral changes associated with brain maturation in 22q11DS re ...

Deficient intracortical inhibition (SICI) during movement preparation after chronic stroke

Friedhelm Christoph Hummel

In healthy subjects, preparation to move is accompanied by motor cortical disinhibition. Poor control of intracortical inhibitory function in the primary motor cortex (M1) might contribute to persistent abnormal motor behavior in the paretic hand after chr ...

Spike detection algorithm improvement, spike waveforms projections with PCA and hierarchical classification

Diego Ghezzi

Definition of single spikes from multiunit spike trains plays a critical role in neurophysiology and in neuroengineering. Moreover, long period analysis are needed to study synaptic plasticity effects and observe the long and medium term development on whi ...
