Bi-directional network remodeling by reactive astrocytes

A Single-Fiber Bi-directional Self-Healing WDM Metro-Ring Network with Bi-directional OADM

We propose and demonstrate a single-fiber bi-directional WDM self-healing ring network with simple bidirectional OADM. By employing our proposed alternate-path switching scheme, the bi-directional traffic can be restored promptly under single fiber failure. Introduction Bi-directional wavelength division multiplexing (WDM) self-healing ring (SHR) network [1-2] is an attractive and cost-effectiv...

Reactive astrocytes promote axonal remodeling and neurological recovery after stroke

Joint Network and LDPC Coding for Bi-directional Relaying

In this paper, we consider joint network and LDPC coding for practically implementing the denosie-and-forward protocol over bi-directional relaying. the closed-form expressions for computing the log-likelihood ratios of the network-coded codewords have been derived for both real and complex multipleaccess channels. It is revealed that the equivalent channel observed at the relay is an asymmetri...

Bi-directional astrocytic regulation of neuronal activity within a network

The concept of a tripartite synapse holds that astrocytes can affect both the pre- and post-synaptic compartments through the Ca(2+)-dependent release of gliotransmitters. Because astrocytic Ca(2+) transients usually last for a few seconds, we assumed that astrocytic regulation of synaptic transmission may also occur on the scale of seconds. Here, we considered the basic physiological functions...

Bi-directional LSTM Recurrent Neural Network for Chinese Word Segmentation

Recurrent neural network(RNN) has been broadly applied to natural language processing(NLP) problems. This kind of neural network is designed for modeling sequential data and has been testified to be quite efficient in sequential tagging tasks. In this paper, we propose to use bi-directional RNN with long short-term memory(LSTM) units for Chinese word segmentation, which is a crucial preprocess ...
