Dreams (2004 film)

Dreams is a 2004 Tamil Malayalam romantic film directed by Kasthuri Raja and produced by Saraswathi Srikanth. The film featured Raja's son Dhanush in the lead role with Diya and Parul Yadav playing other pivotal roles. The film opened to negative reviews and became a failure at the box office.

Cast

Production

The project was launched shortly after the success of Thulluvadho Ilamai in 2002, but as Dhanush's Kaadhal Kondein became a large success, Dreams was stalled temporarily as Dhanush's dates became blocked. The film ran into a legal tussle with the makers of his other film, Sullan, with the producers adamant that Dreams was released first although to no avail. The film's delay meant that Dhanush shot ten straight days for the project to complete it, while the delay also had resulted in failings in continuity. By the time of the release, the producer Srikanth and director Kastoori Raja were still engaged in a legal tussle.

Dreams (Fleetwood Mac song)

"Dreams" is a song written by singer Stevie Nicks, for the group Fleetwood Mac's 1977 album, Rumours. It is the only U.S. No. 1 hit for the group where it sold over a million copies, and remains one of their best known songs.

Background and writing

The members of Fleetwood Mac were experiencing emotional upheavals while recording Rumours. Drummer Mick Fleetwood was going through a divorce. Bassist John McVie was separating from his wife, keyboardist Christine McVie. Guitarist Lindsey Buckingham and lead singer Stevie Nicks were ending their eight-year relationship. "We had to go through this elaborate exercise of denial," explained Buckingham to Blender magazine, "keeping our personal feelings in one corner of the room while trying to be professional in the other."

Nicks wrote the song at the Record Plant studio in Sausalito, California, in early 1976. "One day when I wasn't required in the main studio," remembers singer Stevie Nicks to Blender, "I took a Fender Rhodes piano and went into another studio that was said to belong to Sly, of Sly & the Family Stone. It was a black-and-red room, with a sunken pit in the middle where there was a piano, and a big black-velvet bed with Victorian drapes."

Dreams (Klaus Schulze album)

Dreams is the nineteenth album by Klaus Schulze. It was released in 1986, and in 2005 was the third Schulze album reissued by Revisited Records. The reissue bonus track was released early 2004 in Hambühren as a limited promo CD Ion.

Phelix

Phelix is a high-speed stream cipher with a built-in single-pass message authentication code (MAC) functionality, submitted in 2004 to the eSTREAM contest by Doug Whiting, Bruce Schneier, Stefan Lucks, and Frédéric Muller. The cipher uses only the operations of addition modulo 2³², exclusive or, and rotation by a fixed number of bits. Phelix uses a 256-bit key and a 128-bit nonce, claiming a design strength of 128 bits. Concerns have been raised over the ability to recover the secret key if the cipher is used incorrectly.

Performance

Phelix is optimised for 32-bit platforms. The authors state that it can achieve up to eight cycles per byte on modern x86-based processors.

FPGA Hardware performance figures published in the paper "Review of stream cipher candidates from a low resource hardware perspective" are as follows:

Helix

Phelix is a slightly modified form of an earlier cipher, Helix, published in 2003 by Niels Ferguson, Doug Whiting, Bruce Schneier, John Kelsey, Stefan Lucks, and Tadayoshi Kohno; Phelix adds 128 bits to the internal state.

Pi helix

A pi helix (or π-helix) is a type of secondary structure found in proteins. Although once thought to be rare, short π-helices are found in 15% of known protein structures and are believed to be an evolutionary adaptation derived by the insertion of a single amino acid into an α-helix. Because such insertions are highly destabilizing, the formation of π-helices would tend to be selected against unless it provided some functional advantage to the protein. π-helices therefore are typically found near functional sites of proteins.

Standard structure

The amino acids in a standard π-helix are arranged in a right-handed helical structure. Each amino acid corresponds to an 87° turn in the helix (i.e., the helix has 4.1 residues per turn), and a translation of 1.15 Å (=0.115 nm) along the helical axis. Most importantly, the N-H group of an amino acid forms a hydrogen bond with the C=O group of the amino acid five residues earlier; this repeated i+5→i hydrogen bonding defines a π-helix. Similar structures include the 3₁₀ helix (i+3→i hydrogen bonding) and the α-helix (i+4→i hydrogen bonding).

310 helix

A 3₁₀ helix is a type of secondary structure found (rarely) in proteins and polypeptides.Of the countless protein secondary structures present, the 3₁₀-helix is the fourth most common type observed; following α-helices, β-sheets and reverse turns. 3₁₀-helices constitute nearly 10-15% of all helices in protein secondary structures, and are typically observed as extensions of α-helices found at either their N- or C- termini. Because of the α-helices tendency to consistently fold and unfold, it has been proposed that the 3₁₀-helix serves as an intermediary conformation of sorts, and provides insight into the initiation of α-helix folding.

Discovery

Right around the 1950s, Max Perutz, who was the head of the Medical Research Council at the University of Cambridge, first wrote a paper documenting the elusive 3₁₀-helix. Of those cited in his work, two of his most famous colleagues during these experiments were James Watson and Francis Crick. In his paper, his two main observations regarding the theoretical configurations of polypeptides were as follows:
