In this paper, we present our multichannel neural architecture for recognizing emerging named entity in social media messages, which we applied in the Novel and Emerging Named Entity Recognition shared task at the EMNLP 2017 Workshop on Noisy User-generated Text (W-NUT). We propose a novel approach, which incorporates comprehensive word representations with multichannel information and Conditio...

[Purpose] The purpose of the study was to design and implement a multichannel dynamic functional electrical stimulation system and investigate acute effects of functional electrical stimulation of the tibialis anterior and rectus femoris on ankle and knee sagittal-plane kinematics and related muscle forces of hemiplegic gait. [Subjects and Methods] A multichannel dynamic electrical stimulation ...

Nonlinear multichannel filters have successfully been applied to biomedical signals, multichannel images as well as processing of vector fields. In multichannel signals, component variances and correlations among components may be unequal and time-varying. Such changes can be expressed as an affine transformation of the input signal. In this paper, we investigate how the performance and statist...

In this paper, we address the design of multichannel L-filters based on marginal data ordering using the Mean-Squared-Error as fidelity criterion. Design procedures subject to the constraints of unbiased or location-invariant estimation or without imposing any constraint are discussed. It is shown by simulations that the proposed multichannel L-filters perform better than other multichannel non...

We present the design and test of a portable multichannel neural data acquisition system. Each analog channel features a low noise (10nV/√Hz), high CMRR (83.4dB) input stage, a 4 order bandpass filter and a selectable gain (60.8dB – 100.8dB). An automatic DC restoration circuit in the input stage rejects the electrodes DC voltage mismatch. The multichannel analog signals are sampled, digitized ...

The abilities of single channel cystometry and standard multichannel cystometry to diagnose bladder instability were compared in 100 women taking part in a single blind crossover trial. In 93 of the women both tests yielded the same result. The single channel system detected every case of detrusor instability but in seven women suggested detrusor contractions that were not evident on multichann...
