TL;DR: This paper first analyze specific tweet features through a Principal Component Analysis (PCA) to better understand the behavior of highly forwarded tweets as opposed to those retweeted only a few times, and shows that the selection of only the most correlated features, leads to the best classification accuracy.

TL;DR: The results showed that low ORP affected growth mainly during the early stages of Bacillus cereus anaerobically grown in controlled-batch conditions under low initial oxidoreduction potential using hydrogen gas as reducing agent.
Abstract: In the present study, a food-borne pathogen strain of Bacillus cereus (F4430/73) was anaerobically grown in controlled-batch conditions under low initial oxidoreduction potential (ORP=–148 mV) using hydrogen gas as reducing agent. Its physiological characteristics, including growth, glucose fermentation capacity and enterotoxin production, were compared with anaerobic conditions generated by nitrogen gas (ORP=+ 45 mV). The results showed that low ORP affected growth mainly during the early stages. Maximal specific rates of growth and glucose consumption were reduced, and drastic changes in time profiles of fermentation product concentration were observed. Production of lactate was promoted at the expense of acetate. Nevertheless, low ORP did not affect final biomass yield. Under both ORP conditions, Non-haemolytic enterotoxin (Nhe) was produced early during the exponential growth phase as a first enterotoxin and Haemolysin BL (Hbl) later during the early stationary growth phase as a second enterotoxin. The major effect of low ORP was the strong stimulation of Hbl production and, to a lesser extent, Nhe production. This control was complex, involving different levels of regulation. We discussed the regulation of enterotoxin expression and the involvement of the pleiotropic regulator PlcR.

TL;DR: The growth rates of strains covering the seven major phylogenetic groups of Bacillus cereus sensu lato at a range of temperature, pH, and a(w) were determined and it was shown that cardinal parameters reflected the differences in the temperature adaptation observed between B. cereus phylogeneticgroups I to VII.

TL;DR: CP was found to be linearly correlated to earthworm biomass and to be greatly influenced by soil water content, and it is believed to be of great use as an endpoint in ecotoxicity testing.
