Philadelphia-Baltimore-Washington Stock Exchange
Philadelphia Stock Exchange (PHLX), now known as Nasdaq PHLX, is the first stock exchange established in the United States and the oldest stock exchange in the nation. The exchange is owned by Nasdaq, which acquired it in 2007 for $652 million, and is headquartered in Philadelphia. The exchange was founded in 1790 and originally named the Board of Brokers of Philadelphia and sometimes referred to as the Philadelphia Board of Brokers. In 1875, the Board of Brokers changed its name to the Philadelphia Stock Exchange. In 1949, the exchange merged with the Baltimore Stock Exchange and was renamed the Philadelphia-Baltimore Stock Exchange. In 1954, it merged with the Washington Stock Exchange and was renamed the Philadelphia-Baltimore-Washington Stock Exchange, often abbreviated PBW. In 1969, the exchange acquired the Pittsburgh Stock Exchange. History 1790–1875: Board of Brokers Over its more than 200 years in existence, the Philadelphia Stock Exchange has had various titles a ...

Peanut Butter Wolf
Christopher George Manak (born October 8, 1969 ), better known by his stage name Peanut Butter Wolf, is an American disc jockey and record producer from San Jose, California. He is based in Los Angeles, where he moved to in 2000. He is the founder of Stones Throw Records. Career In 1989, Peanut Butter Wolf met rapper Charizma. They became friends and started making music together. They made a name for themselves in San Jose and the Bay Area through their live shows and demo tapes. Charizma was shot dead in 1993. In 1996, Peanut Butter Wolf founded Stones Throw Records, which would release the duo's '' Big Shots'' in 2003. In 1999, Peanut Butter Wolf released '' My Vinyl Weighs a Ton''. It peaked at number 44 on the UK Independent Albums Chart. In 2010, Jeff Weiss of ''Los Angeles Times'' called it "a crate-digging classic that remains one of the seminal statements of the underground golden era."

Proton Beam Writing
Proton beam writing (or p-beam writing) is a direct-write lithography process that uses a focused beam of high energy (MeV) protons to pattern resist material at nanodimensions. The process, although similar in many ways to direct writing using electrons, nevertheless offers some interesting and unique advantages. Protons, which are approximately 1800 times more massive than electrons, have deeper penetration in materials and travel in an almost straight path. This feature allows the fabrication of three-dimensional, high aspect ratio structures with vertical, smooth sidewalls and low line-edge roughness. Calculations have also indicated that p-beam writing exhibits minimal proximity effects (unwanted exposure due to secondary electrons), since the secondary electrons induced in proton/electron collisions have low energy. A further advantage stems from the ability of protons to displace atoms while traversing material, thereby increasing localized damage especially at the end of rang ...

Play-by-post Role-playing Game
A play-by-post role-playing game (or sim) is an online text-based role-playing game in which players interact with each other and a predefined environment via text. It is a subset of the online role-playing community which caters to both gamers and creative writers. Play-by-post games may be based on other role-playing games, non-game fiction including books, television and movies, or original settings. This activity is closely related to both interactive fiction and collaborative writing. Compared to other roleplaying game formats, this type tends to have the loosest rulesets. History Play-by-post roleplaying has its origins on the large computer networks and bulletin board systems of major universities in the United States in the 1980s. It drew heavily upon the traditions of fanzines and off-line role-playing games. The introduction of IRC enabled users to engage in real-time chat-based role-playing and resulted in the establishment of open communities. Development of fo ...

Prosopography Of The Byzantine World
The Prosopography of the Byzantine World (PBW) is a project to create a prosopographical database of individuals named in textual sources in the Byzantine Empire and surrounding areas in the period from 642 to 1265. The project is a collaboration between the British Academy and the Berlin-Brandenburg Academy of Sciences and Humanities. Origins The project was begun in the 1980s with the aim of completing the work on later Roman Empire and Byzantine prosopography begun by Theodore Mommsen in the 19th century and carried on by A.H.M. Jones and J. R. Martindale, which produced ''The Prosopography of the Later Roman Empire'' (three volumes, Cambridge, 1971–1992), covering the period from 260 (the accession of Gallienus) to 641 (the death of Heraclius, marking the end of late Antiquity). In 1993, the British Academy signed a collaboration agreement with the Berlin-Brandenburg Academy. The work is divided into three periods, 641–867 (Heraclian dynasty to the Amorian dynasty), ...
