introduction: there are evidences showing the role of nitric oxide in the opiate reward properties. the role of nitric oxide signaling pathway as an intracellular mechanism on augmentation of long term potentiation in hippocampal ca1 area of rats is also confirmed. it has been also reported that oral morphine dependence facilitates formation of spatial learning and memory via activation of nmda...

With the increasing amount of video data, it is desirable to highlight or summarize the videos of interest for viewing, search, or storage purposes. However, existing summarization approaches are typically trained from third-person videos, which cannot generalize to highlight the first-person ones. By advancing deep learning techniques, we propose a unique network architecture for transferring ...

Natural language processing tools like part-of-speech taggers and parsers are being used in a variety of applications involving natural language, including RE. Such tools, based on statistical models of language, are learnt via supervised machine learning algorithms from human-annotated data. Due to their dependence on annotated data, which is limited in size and genre, these models have a fall...

Machine learning algorithms can be subdivided into two types, supervised and unsupervised. Supervised learning is the more useful technique when the data samples have known outcomes that the user wants to predict. On the other hand, unsupervised learning is more appropriate when the user does not know the subdivisions into which the data samples, using relevant predictor features, should be div...

being one of the most effective tools for educational system improvement, educational technology plays an important role in learning facilitation. in order to have a deeper, more effective and long lasting learning impact, this systematic approach designs, implements and evaluates the teaching- learning process, using specific purposes, new methods of psychology and communication sciences and a...

Long-term potentiation (LTP) is a form of activity-dependent plasticity that occurs during learning. Potassium channels are the most diverse group of all ion channels that related to synaptic plasticity. Small-conductance calcium-activated potassium channels (SKs) are found in hippocampal CA1 neurons and by inhibiting of postsynaptic potentials are involved in synaptic transmission impairment. ...
