  2. Compare-and-swap - Wikipedia

    en.wikipedia.org/wiki/Compare-and-swap

    Some CAS-based algorithms are affected by and must handle the problem of a false positive match, or the ABA problem. It is possible that between the time the old value is read and the time CAS is attempted, some other processors or threads change the memory location two or more times such that it acquires a bit pattern which matches the old value.

  3. Trimethylsilylacetylene - Wikipedia

    en.wikipedia.org/wiki/Trimethylsilylacetylene

    Trimethylsilylacetylene is used in Sonogashira couplings as the equivalent of acetylene.Using this protected alkyne, as opposed to acetylene itself, prevents further coupling reactions.

  4. Group (periodic table) - Wikipedia

    en.wikipedia.org/wiki/Group_(periodic_table)

    In the periodic table of the elements, each column is a group. In chemistry, a group (also known as a family) [1] is a column of elements in the periodic table of the chemical elements. There are 18 numbered groups in the periodic table; the 14 f-block columns, between groups 2 and 3, are not numbered.

  5. CAS latency - Wikipedia

    en.wikipedia.org/wiki/CAS_latency

    This row is then active, and columns may be accessed for read or write. The CAS latency is the delay between the time at which the column address and the column address strobe signal are presented to the memory module and the time at which the corresponding data is made available by the memory module. The desired row must already be active; if ...

  6. Channel-associated signaling - Wikipedia

    en.wikipedia.org/wiki/Channel-associated_signaling

    Channel-associated signaling (CAS), also known as per-trunk signaling (PTS), is a form of digital communication signaling. As with most telecommunication signaling methods, it uses routing information to direct the payload of voice or data to its destination.

    Here are the best build/buy and CAS kits on offer. ... There are a lot of kits for The Sims 4 – more than 30, in fact. So it's understandable if you're a little overwhelmed by all the choice.

  9. Double compare-and-swap - Wikipedia

    en.wikipedia.org/wiki/Double_compare-and-swap

    More recently, however, it has been shown that an STM can be implemented with comparable properties [clarification needed] using only CAS. [4] An lock-free deque using hazard pointers and requiring only DWCAS rather than full DCAS was proposed by Maged Michael in 2003. [ 5 ]
