Meltdown
The security of computer systems fundamentally relies on memory isolation, e.g., kernel address ranges are marked as non-accessible and are protected from user access. In this paper, we present Meltdown. Meltdown exploits side effects of out-of-order execution on modern processors to read arbitrary kernel-memory locations including personal data and passwords. Out-of-order execution is an indis...

متن کاملMutational meltdown in laboratory yeast populations.
In small or repeatedly bottlenecked populations, mutations are expected to accumulate by genetic drift, causing fitness declines. In mutational meltdown models, such fitness declines further reduce population size, thus accelerating additional mutation accumulation and leading to extinction. Because the rate of mutation accumulation is determined partly by the mutation rate, the risk and rate o...
متن کاملSynergistic interactions of nonindigenous species : Invasional meltdown ?
Study of interactions between pairs or larger groups of nonindigenous species has been subordinated in the literature to study of interactions between nonindigenous and native species. To the extent that interactions among introduced species are depicted at all, the emphasis has been on negative interactions, primarily resource competition and interference. However, a literature search reveals ...
متن کاملMutational Meltdown in Large Sexual Populations
When a new mdividual is formed (independently of the reproduction process) it inherits harmful iuutations. Moreover, new mutations are acquired even in the genetic code formation, most of them deleterious ones. This might lead to a time decay in the mean fitness of the whole population that, for long enough time, ,vould produce the extinction of the
