An alternative method is devised for calculating dynamic stability maps in cylindrical and centerless infeed grinding processes.The method is based on the application of the Floquet theorem by repeated time integrations.Without the need of building the transition matrix, this is the most efficient calculation in terms of computation effort compared
BACKGROUND: Gene expression profiles of bacteria in their natural hosts can provide novel insight into the host-pathogen interactions and molecular determinants of bacterial infections.In the Showman ® Leather Tie On present study, the transcriptional profile of the porcine lung pathogen Actinobacillus pleuropneumoniae was monitored during the acu
One of the primary goals of the space exploration community is to unambiguously detect past or present life outside of Earth.As such, a number of so-called life detection technologies, instruments, and approaches have been applied as part of past, current, and future space missions.As astrobiology is a truly interdisciplinary field within the realm
In many animals, a fast and reliable circuit for discriminating between predator-sized objects and edible (prey-sized) objects is necessary for survival.How are receptive fields in visual brain areas organized to extract information about size? Recent studies from the zebrafish optic tectum and the mouse visual cortex suggest de novo shaping of rec
