Partners for a New Beginning: In his "A New Beginning" speech on June 4, 2009, at Cairo University in Cairo, Egypt, President of the United States Barack Obama stated that "I've come here to Cairo to seek a new beginning between the United States and Muslims around the world, one based on mutual interest and mutual respect, and one based upon the truth that America and Islam are not exclusive and need not be in competition.  Instead, they overlap, and share common principles – principles of justice and progress; tolerance and the dignity of all human beings."  During the speech, he also committed to "host a Summit on Entrepreneurship this year to identify how we can deepen ties between business leaders, foundations and social entrepreneurs in the United States and Muslim communities around the world".

The Ataris: The Ataris are an American rock band from Anderson, Indiana.  Formed in 1995, they have released five studio albums, with "So Long, Astoria" certified gold.  In 2009, an album was announced to be entitled "The Graveyard of the Atlantic" although the album's status has been on indefinite ambiguity, with just two EPs released in 2010 and 2012 both with the same titles as the awaited album.  They are best known for their hit cover song, originally recorded by Don Henley, "The Boys of Summer".

The Lumineers: The Lumineers are an American folk rock/Americana band based in Denver, Colorado.  The founding members are Wesley Schultz (lead vocals, guitar) and Jeremiah Fraites (drums, percussion).  Schultz and Fraites began writing and performing together in Ramsey, New Jersey in 2005.  Cellist and vocalist Neyla Pekarek joined the band in 2010.  The Lumineers emerged as one of the most popular folk rock/Americana artists during the revival of those genres and their growing popularity in the 2010s.  The band's stripped back raw sound draws heavily from artists that influenced Schultz and Fraites such as Bruce Springsteen, Bob Dylan and Tom Petty.  They are known for their energetic live shows and several international hit singles including "Ho Hey”, “Stubborn Love”, “Ophelia” and “Cleopatra”.  The band has become one of the top touring bands in the U.S. and also sells out shows around the world.

Frederick S. Mates: Frederick S. Mates, aka Frederic Mates, founded in August 1967 the Mates Investment Fund, a high-flying mutual fund during the 'Go-Go' 60s that later crashed in the bear market of the early 1970s.  Mates ran his fund from an office he dubbed the "kibbutz" and with a young staff he called his "flower children".  Mates put most of his fund into a letter stock known as Omega Equities.  Mates in determining his funds assets assigned a value to the barely traded Omega of $16 a share, while having purchased the stock at $3.25 a share.  Mates got into trouble over this practice which was routine in the 1960s and not uncommon even today , of accounting for letter stocks at a price different from what was paid for it.  As a result, when confidence was lost in Mates' mutual fund and investors wanted to cash out , redemptions had to be suspended for a while, which the U.S. Securities and Exchange Commission condoned .

Eiroforum: EIROforum is an organization consisting of eight European intergovernmental scientific research organisations devoted to fostering mutual activities.  Presided upon by the Director Generals of the individual organizations, who meet twice a year, the organization aims to identify mutual activities amongst its members to share resources in various fields.

Entanglement-assisted classical capacity: In the theory of quantum communication, the entanglement-assisted classical capacity of a quantum channel is the highest rate at which classical information can be transmitted from a sender to receiver when they share an unlimited amount of noiseless entanglement.  It is given by the quantum mutual information of the channel, which is the input-output quantum mutual information maximized over all pure bipartite quantum states with one system transmitted through the channel.  This formula is the natural generalization of Shannon's noisy channel coding theorem, in the sense that this formula is equal to the capacity, and there is no need to regularize it.  An additional feature that it shares with Shannon's formula is that a noiseless classical or quantum feedback channel cannot increase the entanglement-assisted classical capacity.  The entanglement-assisted classical capacity theorem is proved in two parts: the direct coding theorem and the converse theorem.  The direct coding theorem demonstrates that the quantum mutual information of the channel is an achievable rate, by a random coding strategy that is effectively a noisy version of the super-dense coding protocol.  The converse theorem demonstrates that this rate is optimal by making use of the strong subadditivity of quantum entropy.

Mortgage industry of the United Kingdom: The Mortgage industry of the United Kingdom has traditionally been dominated by building societies, but from the 1970s the share of the new mortgage loans market held by building societies has declined substantially.  Between 1977 and 1987, the share fell drastically from 96% to 66% while that of banks and other institutions rose from 3% to 36%.  The major lenders include building societies, banks, specialized mortgage corporations, insurance companies, and pension funds.  During the four years following the Financial crisis of 2008 the UK mutual sector provided approximately 80% of net lending to the housing market.  There are currently over 200 significant separate financial organizations supplying mortgage loans to house buyers in Britain of which the Lloyds Bank and the Nationwide Building Society have the largest market share.

Collaborative partnership: Collaborative partnerships are agreements and actions made by consenting organizations to share resources to accomplish a mutual goal.  Collaborative partnerships rely on participation by at least two parties who agree to share resources, such as finances, knowledge, and people.  Organizations in a collaborative partnership share common goals.  The essence of collaborative partnership is for all parties to mutually benefit from working together.
