ARM Cortex-A57

The ARM Cortex-A57 is a microarchitecture implementing the ARMv8-A 64-bit instruction set designed by ARM Holdings. The Cortex-A57 is an out-of-order superscalar pipeline. It is available as SIP core to licensees, and its design makes it suitable for integration with other SIP cores (e.g. GPU, display controller, DSP, image processor, etc.) into one die constituting a system on a chip (SoC).

Benko Gambit

The Benko Gambit (or Volga Gambit) is a chess opening characterised by the move 3...b5 in the Benoni Defense arising after:

The Encyclopaedia of Chess Openings (ECO) has three codes for the Benko Gambit:

Origin and predecessors

The idea of sacrificing a pawn with ...b5 and ...a6 is quite old. Karel Opočenský applied the idea against, among others, Gideon Ståhlberg at Poděbrady 1936, Paul Keres at Pärnu 1937, and Erich Eliskases at Prague 1937. Later the Mark Taimanov versus David Bronstein game at the Candidates Tournament, Zürich 1953, drew attention. Most of these games began as a King's Indian, with Black only later playing ...c5 and ...b5. Possibly the first to use the now-standard move order 1.d4 Nf6 2.c4 c5 3.d5 b5 was Thorvaldsson–Vaitonis, Munich Olympiad 1936.

In many countries, particularly in the Eastern Bloc, the opening is known as the Volga Gambit. This name is derived from the Volga River after an article about 3...b5!? by B. Argunow written in Kuibyshev (Samara since 1991), Russia, that was published in the second 1946 issue of the magazine Shakhmaty v SSSR.

Mancunian Way

The Mancunian Way is a two mile long motorway in Manchester, England. It is officially made up of the A57(M) and A635(M) motorways, although the latter does not appear on road signs for practical reasons. It is also part of two other roads: the A57 to the west, which runs east-west through Greater Manchester linking the M602 and M67 motorways, and a short section of non-motorway A635 to the east. Part of this non-motorway section collapsed on 14 August 2015 due to a sinkhole and is currently being repaired.

Route

The road forms a major part of the Manchester-Salford Inner Ring Road and runs south of the city centre. Running eastbound, it starts as a two-lane dual carriageway and passes underneath the A56. Following this, the road widens to three lanes. At the next junction which leads to the A5103, the road reduces to two lanes and becomes an elevated highway. This section runs atop link roads and two roundabouts before reaching the next junction with the A34. At this point the road passes through the centre of the campuses of UMIST (now part of the University of Manchester) and Manchester Metropolitan University. It then runs for around ¾ mile (1.2 km) before reaching its junction with the A6 which it crosses on a bridge before dropping down to ground level. It then finishes on the A635 and continues eastbound, and also continues to be called the Mancunian Way.
