Domain wall

A domain wall is a type of topological soliton that occurs whenever a discrete symmetry is spontaneously broken. Domain walls also sometimes called kinks in analogy with closely related kink solution of the sine-Gordon model. Unstable domain walls can also appear if spontaneously broken discrete symmetry is approximate and there is the metastable vacuum.

A domain (hyper volume) is extended in three spatial dimensions and one time dimension. A domain wall is the boundary between two neighboring domains. Thus a domain wall is extended in two spatial dimensions and one time dimension.

Important examples are:

Besides these important cases similar solitons appear in wide spectrum of the models. Here are other examples:

Domain (band)

Domain is a German power metal band.

History

1986–1992

Domain first impressed fans of melodic metal back in the 1980s with their first works, "Lost In The City" (still under the old band name Kingdom), "Before The Storm" and "Crack in The Wall", as well as with their hit songs such as 'Lost In The City' and ‚ 'I Don’t Wanna Die'. Single "Heart Of Stone was a title song of german mini-serial "Bastard".

2000–2006

But it was their next albums, "One Million Lightyears From Home" (2001), "The Artefact" (2002) and "The Sixth Dimension" (2003) as well as a successful tour with the rock legends, Glenn Hughes and Joe Lynn Turner (HTP) that secured the quintet a place in the European Melodic Metal scene. With a harder edged sound, Domain still had a good following. And that was when the career of the guitarist Axel "Ironfinger" Ritt (Grave Digger), ex-vocalist Carsten Lizard Schulz (Evidence One et al.), and the long-term band mates keyboarder Erdmann Lange, ex-bass player Jochen Mayer (Boysvoice, Demon Drive, Casanova) and the ex-drummer Stefan Köllner really began…

Domain of a function

In mathematics, and more specifically in naive set theory, the domain of definition (or simply the domain) of a function is the set of "input" or argument values for which the function is defined. That is, the function provides an "output" or value for each member of the domain. Conversely, the set of values the function takes on as output is termed the image of the function, which is sometimes also referred to as the range of the function.

For instance, the domain of cosine is the set of all real numbers, while the domain of the square root consists only of numbers greater than or equal to 0 (ignoring complex numbers in both cases). When the domain of a function is a subset of the real numbers, and the function is represented in an xy Cartesian coordinate system, the domain is represented on the x-axis.

Formal definition

Given a function f:X→Y, the set X is the domain of f; the set Y is the codomain of f. In the expression f(x), x is the argument and f(x) is the value. One can think of an argument as an input to the function, and the value as the output.

Law of agency

The law of agency is an area of commercial law dealing with a set of contractual, quasi-contractual and non-contractual fiduciary relationships that involve a person, called the agent, that is authorized to act on behalf of another (called the principal) to create legal relations with a third party. Succinctly, it may be referred to as the equal relationship between a principal and an agent whereby the principal, expressly or implicitly, authorizes the agent to work under his or her control and on his or her behalf. The agent is, thus, required to negotiate on behalf of the principal or bring him or her and third parties into contractual relationship. This branch of law separates and regulates the relationships between:

In 1986, the European Communities enacted Directive 86/653/EEC on self-employed commercial agents. In the UK, this was implemented into national law in the Commercial Agents Regulations 1993.

Patent attorney

A patent attorney is an attorney who has the specialized qualifications necessary for representing clients in obtaining patents and acting in all matters and procedures relating to patent law and practice, such as filing an opposition. The term is used differently in different countries, and thus may or may not require the same legal qualifications as a general legal practitioner.

The titles patent agent and patent lawyer are also used in some jurisdictions. In some jurisdictions the terms are interchangeable, while in others the latter is used only if the person qualified as a lawyer.

Qualification regimes

In Europe, requirements for practising as patent attorney before national patent offices should be distinguished from those needed for practising before the European Patent Office (EPO) or the Eurasian Patent Office (EAPO). On the national level, the requirements are not harmonized, although across the 28 Member States of the European Union respective professional qualifications are mutually recognised to some degree.

Agent (video game)

Agent is an upcoming stealth action video game developed by Rockstar North. In July 2007, Sony announced that Rockstar was working on a new exclusive game for the PlayStation 3, but details of the project, including its title, were not announced until June 2009 during the Sony press conference at E3.

The game is set during the Cold War and will take players into "the world of counter-intelligence, espionage and political assassinations", according to a Rockstar press release. Rockstar has yet to reveal any details regarding the setting other than that it will be set in the late 1970s.

Announced in 2007 exclusively for PS3, little was heard about the game after 2009 and it was thought to have been cancelled, although Take-Two confirmed in May 2011 that Agent was still in development. In July 2013, Take-Two Interactive registered two trademarks for the game.

Development

Sony Computer Entertainment announced that Rockstar Games was working on a new franchise for the PlayStation 3 in July 2007. Michael Shorrock, SCEA's director of third-party relations, wrote on the official US PlayStation blog, "as part of our long standing relationship with Rockstar, and the incredible success for both companies with the cultural icon that is Grand Theft Auto we've agreed to the PlayStation exclusive rights of the next great franchise from the Rockstar studios." Nothing more was revealed about the new franchise except the clarification that it would not be L.A. Noire. According to Shorrock, "Rockstar really wanted to make a game that you can truly only do on PS3" and added that the reason Sony locked the IP down as an exclusive deal was because Sony believed the franchise would "set the bar for the rest of the industry." Ben Feder, former president of Rockstar parent Take-Two Interactive, said that the game would be "genre-defining" and "a whole new way of experiencing videogames that we haven't really seen before."
