EMG-based pattern recognition approach in post stroke robot-aided rehabilitation: a feasibility study

Background: Several studies investigating the use of electromyographic (EMG) signals in robot-based stroke neurorehabilitation to enhance functional recovery. Here we explored whether a classical EMG-based patterns recognition approach could be employed to ...

Synaptic Plasticity in Neural Networks Needs Homeostasis with a Fast Rate Detector

Wulfram Gerstner, Friedemann Zenke, Guillaume Hennequin

Hebbian changes of excitatory synapses are driven by and further enhance correlations between pre- and postsynaptic activities. Hence, Hebbian plasticity forms a positive feedback loop that can lead to instability in simulated neural networks. To keep acti ...

Autolysosomal β-catenin degradation regulates Wnt-autophagy-p62 crosstalk

Paloma Ordonez Moran

Abstract The Wnt/β-catenin signalling and autophagy pathways each play important roles during development, adult tissue homeostasis and tumorigenesis. Here we identify the Wnt/β-catenin signalling pathway as a negative regulator of both basal and stress-in ...

Optimal operating points of oscillators using nonlinear resonators

Luis Guillermo Villanueva Torrijo

We demonstrate an analytical method for calculating the phase sensitivity of a class of oscillators whose phase does not affect the time evolution of the other dynamic variables. We show that such oscillators possess the possibility for complete phase nois ...

On Two Unicast Wireless Networks with Destination-to-Source Feedback

I-Hsiang Wang

In this paper we study the role of feedback in layered two unicast wireless networks with arbitrary number of nodes and connectivity. The feedback model allows destinations to feedback their received signals to their respective sources. In the case of line ...

Feedback-based Coding Algorithms for Braodcast Erasure Channels with Degraded Message Sets

Christina Fragouli

We consider single-hop broadcast packet erasure channels (BPEC) with degraded message sets and instantaneous feedback regularly available from all receivers, and demonstrate that the main principles of the virtual-queue-based algorithms in [1], which were ...

A synthetic review of feedbacks and drivers of shrub encroachment in arid grasslands

Paolo d'Odorico

Many arid grasslands around the world are affected by woody plant encroachment and by the replacement of a relatively continuous grass cover with shrub patches bordered by bare soil. This shift in plant community composition is often abrupt in space and ti ...

Tactile Feedback Improves Performance in a Palpation Task: Results in a VR-Based Testbed

Hannes Bleuler, Roger Gassert, Evren Samur, Laura Santos Carreras, Kaspar Leuenberger

Robotic surgery provides many benefits such as reduced invasiveness and increased dexterity. This comes at the cost of no direct contact between surgeon and patient This physical separation prevents surgeons from performing direct haptic exploration of tis ...

Phase-locked loop based on nanoelectromechanical resonant-body field effect transistor

Mihai Adrian Ionescu, Alexandru Rusu, Sebastian Thimotee Bartsch

We demonstrate the room-temperature operation of a silicon nanoelectromechanical resonant-body field effect transistor (RB-FET) embedded into phase-locked loop (PLL). The very-high frequency resonator uses on-chip electrostatic actuation and transistor-bas ...
