Sun

The Sun (in Greek: Helios, in Latin: Sol) is the star at the center of the Solar System and is by far the most important source of energy for life on Earth. It is a nearly perfect spherical ball of hot plasma, with internal convective motion that generates a magnetic field via a dynamo process. Its diameter is about 109 times that of Earth, and it has a mass about 330,000 times that of Earth, accounting for about 99.86% of the total mass of the Solar System.About three quarters of the Sun's mass consists of hydrogen; the rest is mostly helium, with much smaller quantities of heavier elements, including oxygen, carbon, neon and iron.

The Sun is a G-type main-sequence star (G2V) based on spectral class and it is informally referred to as a yellow dwarf. It formed approximately 4.567 billion years ago from the gravitational collapse of matter within a region of a large molecular cloud. Most of this matter gathered in the center, whereas the rest flattened into an orbiting disk that became the Solar System. The central mass became increasingly hot and dense, eventually initiating nuclear fusion in its core. It is thought that almost all stars form by this process.

Sun (Cat Power album)

Sun is the ninth studio album by American musician Cat Power. Her first album of all-original material since 2006's The Greatest, it was released on September 3, 2012, in the United Kingdom and in the United States on September 4, 2012, via Matador Records. The album was issued in a variety of formats, including a limited edition deluxe LP containing a 7" vinyl of bonus tracks.

The album's lead single, "Ruin", was released for free download at Matador Record's store on June 20, 2012. A music video for album opener "Cherokee", directed by Marshall, was later released, while an ambient remix of the song by Nicolas Jaar is available to download from Cat Power's official website. The song was premièred on NPR's All Songs Considered on June 26, whose host Bob Boilen described the album as "[going in] yet another direction. A lot more drive, a lot more electronics, drum machines, synths—it's very bold."

On April 10, 2013, Cat Power performed the previously unreleased track "Bully" on the opening episode of the forty-second series of Later... with Jools Holland. Immediately following the broadcast, a new version of the album containing "Bully" as a bonus track was made available for download through iTunes.

Inferno (horse)

Inferno (1902–1919) was a Canadian Thoroughbred racehorse. He has been called "Canada's first great racehorse" by the Canadian Horse Racing Hall of Fame.

Background

He was owned and bred by distilling magnate Joseph E. Seagram, who in 1906 was voted president of the Ontario Jockey Club.

Inferno was out of the mare Bon Ino, who was owned and raced by Seagram and had won the 1898 Queen's Plate. Inferno's sire was Havoc, a stallion who ended his career as the sire of four King's Plate winners. Havoc was a son of Himyar, the Champion Sire in North America in 1893 who notably also produced U.S. Racing Hall of Fame inductee Domino. Inferno was a very raucous horse and was a danger to his handlers.

Racing career

He was conditioned for racing by New Jersey-born trainer Barry Littlefield. In 1905, the three-year-old Inferno won Canada's most prestigious race, the King's Plate. That year, he also finished second in both the Toronto Autumn Cup and the King Edward Gold Cup. In 1906, he was again second in the Toronto Autumn Cup but won the Durham Cup Handicap and the first of three consecutive King Edward Gold Cups. The following year, Inferno won his second King Edward Cup plus the Toronto Autumn Cup, and in 1908 he won his second Durham Cup and made it three wins in a row in the King Edward Gold Cup. In addition, his owner joined the Whitney family and other wealthy American elite in bringing horses to compete during the fashionable summer racing season at Saratoga Race Course in Saratoga Springs, New York. Inferno raced until age six and was part of Joseph Seagram's stable to race at Saratoga, where he won two important handicaps.

Inferno (operating system)

Inferno is a distributed operating system started at Bell Labs, but is now developed and maintained by Vita Nuova Holdings as free software. Inferno was based on the experience gained with Plan 9 from Bell Labs, and the further research of Bell Labs into operating systems, languages, on-the-fly compilers, graphics, security, networking and portability. The name of the operating system and many of its associated programs, as well as that of the current company, were inspired by Dante Alighieri's Divine Comedy.

Inferno programs are portable across a broad mix of hardware, networks, and environments. It defines a virtual machine, known as Dis, that can be implemented on any real machine, provides Limbo, a type-safe language that is compiled to portable byte code, and, more significantly, it includes a virtual operating system that supplies the same interfaces whether Inferno runs natively on hardware or runs as a user program on top of another operating system.

A communications protocol called Styx is applied uniformly to access both local and remote resources, which programs use by calling standard file operations, open, read, write, and close. As of the fourth edition of Inferno, Styx is identical to Plan 9's newer version of its hallmark 9P protocol, 9P2000.

CCP4 (file format)

The CCP4 file format is file generated by the Collaborative Computational Project Number 4 in 1979. The file format for electron density has become industry standard in X-ray crystallography and Cryo-electron microscopy where the result of the technique is a three-dimensional grid of voxels each with a value corresponding to density of electrons (see wave function) The CCP4 format is supported by almost every molecular graphics suite that supports volumetric data. The major packages include:
