  2. Coalescence (physics) - Wikipedia

    en.wikipedia.org/wiki/Coalescence_(physics)

    Representation of the coalescence of two droplets, bubbles, or particles to form a single entity. Coalescence is the process by which two or more droplets, bubbles, or particles merge during contact to form a single daughter droplet, bubble, or particle.

  3. Register allocation - Wikipedia

    en.wikipedia.org/wiki/Register_allocation

    Coalesce: merge the live ranges of non-interfering variables related by copy instructions. Spill cost : compute the spill cost of each variable. This assesses the impact of mapping a variable to memory on the speed of the final program.

  4. Coalescent theory - Wikipedia

    en.wikipedia.org/wiki/Coalescent_theory

    Coalescent theory is a model of how alleles sampled from a population may have originated from a common ancestor.In the simplest case, coalescent theory assumes no recombination, no natural selection, and no gene flow or population structure, meaning that each variant is equally likely to have been passed from one generation to the next.

  5. Coalescer - Wikipedia

    en.wikipedia.org/wiki/Coalescer

    A coalescer is a device which induces coalescence in a medium. They are primarily used to separate emulsions into their components via various processes, operating in reverse to an emulsifier.

  6. Multispecies coalescent process - Wikipedia

    en.wikipedia.org/wiki/Multispecies_coalescent...

    In the type 1 tree the alleles in species A and B coalesce after the speciation event that separated the A-B lineage from the C lineage. In the type 2 tree the alleles in species A and B coalesce before the speciation event that separated the A-B lineage from the C lineage (in other words, the type 2 tree is a deep coalescence tree). The type 1 ...

    en.wikipedia.org/wiki/Coalescence

    COALESCE, an SQL function that selects the first non-null from a range of values; Null coalescing operator, a binary operator that is part of the syntax for a basic conditional expression in several programming languages; Coalesced hashing, a strategy of hash collision resolution in computing

  8. Fixed vs. variable interest rates: How these rate types work ...

    www.aol.com/finance/fixed-vs-variable-interest...

    Variable rates are often a better option for interest-earning products when the Fed rate is low. That’s because you’ll have a chance of earning more interest in the future if interest rates rise.

  9. Mandelstam variables - Wikipedia

    en.wikipedia.org/wiki/Mandelstam_variables

    In this diagram, two particles come in with momenta p 1 and p 2, they interact in some fashion, and then two particles with different momentum (p 3 and p 4) leave.. In theoretical physics, the Mandelstam variables are numerical quantities that encode the energy, momentum, and angles of particles in a scattering process in a Lorentz-invariant fashion.
