This does not exclude the possibility, that larger structural fragments (such as tetra-mers and pentamers) can also contribute to the low-frequency vibrational spectrum around the boson peak. On the basis of these results, the following model of the glass transition of glycerol can be proposed. At temperatures far above Tg (186 K), the lifetime of the MRO(More)
We propose a catalytic growth mechanism of single-wall carbon nanotubes based on density functional total energy calculations. Our results indicate nanotubes with an " armchair " edge to be energetically favored over " zigzag " nanotubes. We also suggest that highly mobile Ni catalyst atoms adsorb at the growing edge of the nanotube, where they catalyze the(More)
Gene expression is mediated by specialized cis-regulatory modules (CRMs), the most prominent of which are called enhancers. Early experiments indicated that enhancers located far from the gene promoters are often responsible for mediating gene transcription. Knowing their properties, regulatory activity, and genomic targets is crucial to the functional(More)
—Enhancers are short DNA sequences that modulate gene expression patterns. Recent studies have shown that enhancer elements could be enriched for certain histone modification combinatorial codes, leading to interest in developing computational models to predict enhancer locations. Here we present EP-DNN, a protocol for predicting enhancers based on(More)
