Explosive invasion of plant mitochondria by a group I intron.
Group I introns are mobile, self-splicing genetic elements found principally in organellar genomes and nuclear rRNA genes. The only group I intron known from mitochondrial genomes of vascular plants is located in the cox1 gene of Peperomia, where it is thought to have been recently acquired by lateral transfer from a fungal donor. Southern-blot surveys of 335 diverse genera of land plants now s...
متن کاملSuppression effect on explosive percolations
Percolation transitions (PTs) of networks, leading to the formation of a macroscopic cluster, are conventionally considered to be continuous transitions. However, a modified version of the classical random graph model was introduced in which the growth of clusters was suppressed, and a PT occurs explosively at a delayed transition point. Whether the explosive PT is indeed discontinuous or conti...
متن کاملOn Evaluation of Adaptation Engines
At the core of adaptive learning systems is an adaptation engine which decides the adaptations based on the learner’s profile, educational activity, infrastructure and/or environment. This paper presents a model for adaptation engines. Then it presents 17 criteria for the evaluation of an adaptation engine.
متن کاملDevelopment of a Mathematical Model for Prediction of Pollutants Emission in D. I. Diesel Engines
Major pollutants emission from Direct-Injection (D.I) diesel engines are predicted by means of a mathematical model. In order to construct such a model, an integral Multi-Zone Combustion Model (MZCM) is formulated, which basically consists of jet mixing and combustion submodels. In MZCM, variation of injection pressure is considered. Also time period of ignition delay is predicted by considerin...
متن کاملExplosive genetic evidence for explosive human population growth.
The advent of next-generation sequencing technology has allowed the collection of vast amounts of genetic variation data. A recurring discovery from studying larger and larger samples of individuals had been the extreme, previously unexpected, excess of very rare genetic variants, which has been shown to be mostly due to the recent explosive growth of human populations. Here, we review recent l...
