ARC (file format)

ARC is a lossless data compression and archival format by System Enhancement Associates (SEA). It was very popular during the early days of networked dial-up BBS. The file format and the program were both called ARC. The ARC program made obsolete the previous use of a combination of the SQ program to compress files and the LU program to create .LBR archives, by combining both compression and archiving functions into a single program. Unlike ZIP, ARC is incapable of compressing entire directory trees. The format was subject to controversy in the 1980s—an important event in debates over what would later be known as open formats.

The .arc file extension is often used for several file archive-like file types. For example, the Internet Archive uses its own ARC format to store multiple web resources into a single file. The FreeArc archiver also uses .arc extension, but uses a completely different file format.

Nintendo uses an unrelated 'ARC' format for resources, such as MIDI, voice samples, or text, in GameCube and Wii games. Several unofficial extractors exist for this type of ARC file.

Arc (projective geometry)

A (simple) arc in finite projective geometry is a set of points which satisfies, in an intuitive way, a feature of curved figures in continuous geometries. Loosely speaking, they are sets of points that are far from "line-like" in a plane or far from "plane-like" in a three-dimensional space. In this finite setting it is typical to include the number of points in the set in the name, so these simple arcs are called k-arcs. An important generalization of the k-arc concept, also referred to as arcs in the literature, are the (k, d)-arcs.

k-arcs in a projective plane

In a finite projective plane π (not necessarily Desarguesian) a set A of k (k ≥ 3) points such that no three points of A are collinear (on a line) is called a k - arc. If the plane π has order q then k ≤ q + 2, however the maximum value of k can only be achieved if q is even. In a plane of order q, a (q + 1)-arc is called an oval and, if q is even, a (q + 2)-arc is called a hyperoval.

Every conic in the Desarguesian projective plane PG(2,q), i.e., the set of zeros of an irreducible homogeneous quadratic equation, is an oval. A celebrated result of Beniamino Segre states that when q is odd, every (q + 1)-arc in PG(2,q) is a conic. This is one of the pioneering results in finite geometry.

Directed graph

In mathematics, and more specifically in graph theory, a directed graph (or digraph) is a graph, or set of vertices connected by edges, where the edges have a direction associated with them. In formal terms, a directed graph is an ordered pair G = (V, A) (sometimes G = (V, E)) where

It differs from an ordinary or undirected graph, in that the latter is defined in terms of unordered pairs of vertices, which are usually called edges, arcs, or lines.

A directed graph is called a simple digraph if it has no multiple arrows (two or more edges that connect the same two vertices in the same direction) and no loops (edges that connect vertices to themselves). A directed graph is called a directed multigraph or multidigraph if it may have multiple arrows (and sometimes loops). In the latter case the arrow set forms a multiset, rather than a set, of ordered pairs of vertices.

Loss (comics)

Loss is a mutant comic book character. She has been a member of both the Morlocks and later on of Gene Nation. She first appeared in Storm #3.

Fictional character biography

Born into the Morlock tribe she was whisked away to "The Hill" where she and her fellow young Morlocks aged at an accelerated rate until they came of age and were known as gene nationals. To attest to her fighting prowess she was made a member of Mikhail’s personal guard. Her team helped Mikhail in his attack against Storm but she quickly turned the tables and after liberating them from the Darwinist world set them up in an African village so they could live above ground and atone for past sins.

She has remained a mainstay with her team until D'Gard was made leader and they faced hate mongers. She remains with them until now, and it is unknown if she lost or retained her powers after M-Day.

Powers and abilities

Loss had blue hued skin and blond hair her mutation consisted of metallic spikes which protruded from her skin. She even had retractable spikes in her arms much like Wolverine's claws.

Loss (film)

Loss (Lithuanian: Nereikalingi žmonės, literary "Unnecessary people") is a 2008 Lithuanian psychological thriller film directed, co-written and co-produced by Latvian film director Māris Martinsons. In October 2008, it was announced that the film was Lithuania's submission for the Academy Award for Best Foreign Language Film in the 81st Academy Awards, becoming the first Lithuanian feature film ever to be submitted for the Academy Awards.

Awards

International premiere of Loss was held in 2008 Shanghai International Film Festival, where it was awarded with 2 Jin Jue (Golden Goblet) awards: Best Director for Māris Martinsons and Best Music for Andrius Mamontovas. It is the first Lithuanian feature film to be screened in the competition of A class festival and awarded prestigious prizes.

In 2009 Loss was awarded with the Lielais Kristaps award, Latvia's highest prize awarded in cinema.

Synopsis

Loss is a story about a Priest (starring Andrius Mamontovas) in Ireland who meets a woman Valda (starring Valda Bičkutė) from his native Lithuania only to find out her mysterious identity is closely connected with a darkest secret of his past.
