1960 Campionato Italiano season: The 1960 Campionatio Italiano was the 3rd season of the Campionato Italiano.  Renato Pirocchi won this championship.  Many rounds were run in conjunction 1960 Campionatio A.N.P.E.C./Auto Italiana d’Europa (World Car Trophy Italian ANPEC), which saw Colin Davis win the title.

Exhaustive ballot: The exhaustive ballot is a voting system used to elect a single winner.  Under the exhaustive ballot the elector simply casts a single vote for his or her favorite candidate.  However, if no candidate is supported by an overall majority of votes then the candidate with the fewest votes is eliminated and a further round of voting occurs.  This process is repeated for as many rounds as necessary until one candidate has a majority.

2009–10 Kansas Jayhawks men's basketball team: On April 13, 2009 key players Sherron Collins and Cole Aldrich announced that they would forgo the NBA draft and return for the 2009–10 season.

Contingent vote: The contingent vote is an electoral system used to elect a single winner, in which the voter ranks the candidates in order of preference.  In an election, if no candidate receives an absolute majority of first preference votes, then all but the two leading candidates are eliminated and there is a second count.  In the second count, the votes of those who supported eliminated candidates are distributed among the two remaining candidates, so that one candidate achieves an absolute majority.  The contingent vote is similar to the alternative vote but differs from it in that the alternative vote typically allows for many rounds of counting, whereas under the contingent vote there are never more than two.  In the United States both the contingent vote and the alternative vote are often referred to as variants of instant-runoff voting.  The contingent vote can also be considered a compressed form of the two round system (runoff system), in which both 'rounds' occur without the need for voters to go to the polls twice.

Seeding is based on regular season records.

Rocket (band): Rocket are an alternative rock, post grunge, rocknroll group formed in Los Angeles, California.  They are known for their up-beat sound and high energy performances.  Members are Janelle Barreto (vocals), Eric Wibbelsmann (guitar), Steven Kilcullen (rhythm guitar), Jordan Lawson (bass), and Paul DePatie (drums).  Wibbelsmann and DePatie were previously in a band called The Pills and had lost their lead singer.  They placed an ad on Craigslist listing influence bands like Soundgarden, Pearl Jam, Stone Temple Pilots and Jane’s Addiction, which attracted Barreto who then responded.  After many rounds of meeting and auditioning singers from all walks of life, they offered Barreto the job.  The band began performing in and around the LA area until around July of 2017 when their original bass player Bill Luna left the group due to creative differences.  The three other members began auditioning again, only this time they were seeing new bassists and also hoping for another guitarist to complete the five piece band they envisioned.  After a month's worth of searching and vibing out many other musicians, the band hired Lawson as their new bassist and Kilcullen to play rhythm guitar.  The newly formed group are currently completing an EP "Get Huge" which is set for release in late 2017, performing bigger venues and gaining much more popularity with their new lineup and material.

QIP (complexity): In computational complexity theory, the class QIP, which stands for Quantum Interactive Polynomial time, is the quantum computing analogue of the classical complexity class IP, which is the set of problems solvable by an interactive proof system with a polynomial-time verifier and one computationally unbounded prover.  Informally, IP is the set of languages for which a computationally unbounded prover can convince a polynomial-time verifier to accept when the input is in the language (with high probability) and cannot convince the verifier to accept when the input is not in the language (again, with high probability).  In other words, the prover and verifier may interact for polynomially many rounds, and if the input is in the language the verifier should accept with probability greater than 2/3, and if the input is not in the language, the verifier should be reject with probability greater than 2/3.  In IP, the verifier is like a BPP machine.  In QIP, the communication between the prover and verifier is quantum, and the verifier can perform quantum computation.  In this case the verifier is like a BQP machine.
