Blend modes

Blend modes (or Mixing modes) in digital image editing are used to determine how two layers are blended into each other. The default blend mode in most applications is simply to hide the lower layer with whatever is present in the top layer. However, as each pixel has a numerical representation, a large number of ways to blend two layers is possible. Note that the top layer is not necessarily called a "layer" in the application. It may be applied with a painting or editing tool.

Most graphics editing programs, like Adobe Photoshop and GIMP, allow the user to modify the basic blend modes - for example by applying different levels of opacity to the top picture.

Normal blend mode

This is the standard blend mode which uses the top layer alone, without mixing its colors with the layer beneath it.

Where a is the value of a color channel in the underlying layer, and b is that of the corresponding channel of the upper layer. The result is most typically merged into the bottom layer using "simple" (b over a) alpha compositing, but other Porter-Duff operations are possible. The compositing step results in the top layer's shape, as defined by its alpha channel, appearing over the bottom layer.

Screen (ice hockey)

In ice hockey, a screen is obstruction by a player of the goaltender's view of the puck. The word can also be used as a verb, commonly "don't screen the goaltender", or "the goalie was screened". Screens can be both planned, as when an attacking forward positions himself in front of the net, or accidental, like when a defensemen accidentally blocks the goalie's view. Attacking players may attempt to take advantage of a screen by taking a shot, which the opposing goalie cannot attempt to save if he is being screened.

Tomas Holmström, Darcy Tucker, Ryan Kesler, and Ryan Smyth are known for screening goalies.

Jīva (Jainism)

The Jīva or Atman (/ˈɑːtmən/; Sanskrit: आत्मन्) is a philosophical term used within Jainism to identify the soul. It is one's true self (hence generally translated into English as 'Self') beyond identification with the phenomenal reality of worldly existence. As per the Jain cosmology, jīva or soul is also the principle of sentience and is one of the tattvas or one of the fundamental substances forming part of the universe. According to The Theosophist, "some religionists hold that Atman (Spirit) and Paramatman (God) are one, while others assert that they are distinct ; but a Jain will say that Atman and Paramatman are one as well as distinct." In Jainism, spiritual disciplines, such as abstinence, aid in freeing the jīva "from the body by diminishing and finally extinguishing the functions of the body." Jain philosophy is essentially dualistic. It differentiates two substances, the self and the non-self.

Real Self

According to the Jain text, Samayasāra (The Nature of the Self):-

Life (manga)

Life (Japanese: ライフ, Hepburn: Raifu) is a shōjo manga series created by Keiko Suenobu, a manga creator well known for her work on Vitamin and Happy Tomorrow. Life was serialized in Bessatsu Friend, a publication of Kodansha, and deals with many controversial topics such as self-mutilation, bullying, rape, suicide, and manipulation. In 2006, it won the Kodansha Manga Award for shōjo.

The English language version of the manga, published by Tokyopop, was originally rated OT (Older Teen; 16+), but starting with the release of Volume 6 and carrying back over to future reprintings of the previous five, the rating was changed to M (Mature; 18+) for extremely explicit content in that volume. As of June 2008, nine volumes have been released in the United States; Volume 10 was scheduled for a September 2008 release, but on August 31, 2009, Kodansha (original Japanese publisher of the series) announced that they would drop their manga licensing contract with Tokyopop, leaving Life and other well-known series such as Rave Master unfinished, whether permanently or until picked up by other manga publishing companies (Dark Horse Manga and Del Rey Manga have already picked up certain titles). Kodansha also did not offer an explanation for their decision. The future of the English version of the manga is unknown, as Tokyopop itself shut down in May 2011 after they were faced with bankruptcy.

Life (Sly and the Family Stone album)

Life is the third studio album by funk/soul band Sly and the Family Stone, released in September 1968 on Epic/CBS Records.

Music

Unlike its predecessor, Dance to the Music, Life was not a commercial success, although it has received mostly positive reviews from music critics over the years. Many of its songs, including "M'Lady", "Fun", "Love City", as well as the title track, became popular staples in the Family Stone's live show. A middle ground between the fiery A Whole New Thing and the more commercial Dance to the Music, Life features very little use of studio effects, and is instead more driven by frontman Sly Stone's compositions. Topics for the album's songs include the dating scene ("Dynamite!", "Chicken", "M'Lady"), groupies ("Jane is a Groupee"), and "plastic" (or "fake") people (the Beatlesque "Plastic Jim"). Of particular note is that the Family Stone's main themes of unity and integration are explored here in several songs ("Fun", "Harmony", "Life", and "Love City"). The next Family Stone LP, Stand!, would focus almost exclusively on these topics.

Happy (Surface song)

"Happy" is a song originally recorded by British funk band Hi-Tension in 1984, titled as "You Make Me Happy". In 1987, it was covered by Surface from their self-titled album. A hit single, Surface's version reached number 20 on the Billboard Hot 100 chart and number 16 on the Hot Dance Music/Maxi-Singles Sales chart. "Happy" was also featured on Surface's album Perfect 10 and was produced by Bernard Jackson, David "Pic" Conley and David Townsend.

Haplochromine

The haplochromine cichlids are a tribe of cichlids in subfamily Pseudocrenilabrinae called Haplochromini. This group includes the type genus (Haplochromis) plus a number of closely related genera such as Aulonocara, Astatotilapia, and Chilotilapia. They are endemic to eastern and southern Africa. A common name in a scientific context is East African cichlids – while they are not restricted to that region, they are the dominant Cichlidae there. This tribe was extensively studied by Ethelwynn Trewavas, who made major reviews in 1935 and 1989, at the beginning and at the end of her career in ichthyology. Even today, numerous new species are being described each year.

The haplochromines were in older times treated as subfamily Haplochrominae, However, the great African radiation of pseudocrenilabrine cichlids is certainly not monophyletic without them, and thus they are today ranked as a tribe therein. They do include, however, the type genus of the subfamily, Pseudocrenilabrus. Since taxonomic tribes are treated like genera for purposes of biological nomenclature according to the ICZN, the Haplochromis is the type genus of this tribe, and not the (later-described) Pseudocrenilabrus, even though the tribe name Pseudocrenilabrini was proposed earlier.
