Normally, we expect to see air gradually decline in temperature with altitude. An inversion, or thermal inversion, occurs when there is a layer of warm air above colder air. Because the warm air is more buoyant, the cooler air is trapped can is not circulate as air would normally. Serious air quality problems in cities can occur when an ...

  • Chromosomal inversions or deletion with human disorders

    Like other types of mutations, inversions evolve under selection and random drift. Many inversions, particularly small ones in intergenic regions, are likely to evolve neutrally (by drift alone).

  • order-statistic tree to count the number of inversions

    Thus, an increasing sequence has no inversions. A decreasing list has the maximum number of inversions, n(n-1)/2. I believe we start by letting k be the number of inversions in the sequence.
