Review and classification of electric load forecasting (LF) techniques based on artificial neuralnetworks (ANN) is presented. A basic ANNs architectures used in LF reviewed. A wide range of ANNoriented applications for forecasting are given in the literature. These are classified into five groups:(1) ANNs in short-term LF, (2) ANNs in mid-term LF, (3) ANNs in long-term LF, (4) Hybrid ANNs inLF,...

PLOS Biology announces a new article type, Open Highlights, which uses a recent research article to nucleate a short synthesis of up to ten related research articles from other PLOS journals and from the wider Open Access corpus.

BACKGROUND Percutaneous vertebroplasty (PVP) and percutaneous balloon kyphoplasty (PKP) can increase bone strength as well as alleviate the pain caused by vertebral compression fractures (VCFs), and both procedures rely on polymethyl methacrylate (PMMA) cement injected into the fractured vertebra for mechanical stabilization of the VCFs. However, there is debate over which of these 2 surgical p...

PURPOSE To review the association between sleep duration and self-rated health. METHODS A search for original and review articles focusing on sleep duration and self-rated health was performed in PubMed. The general search strategy was [("sleep duration" OR "total sleep time" OR "time in bed") AND "self-rated health"]. RESULTS We found 22 articles in the English language; 8 articles with no...

The article supports the idea of providing infrastructure and training for preparing and publishing quality video articles. Properly edited, formatted, and verified video items can present graphic contents of interest to the global scientific community. It is suggested to apply traditional attributes of scholarly articles to video items and aggregate them on a specifically designed editing, pub...
