Sun is the second stand-alone production album created by Thomas J. Bergersen from Two Steps from Hell, released on September 30, 2014. The release contains 16 tracks, featuring vocal performances by Merethe Soltvedt, Molly Conole and other vocalists. The album cover and artwork are designed by Bergersen himself. The album was announced for pre-order on September 9 across iTunes, Amazon, and CD Baby, with the tracks "Empire of Angels," "Final Frontier," and "Starchild" made available on iTunes prior to the full release. In addition, a signed limited deluxe edition CD version has been scheduled for somewhere in 2015, set to include additional music, notes on each track written by Thomas, and a large-size poster featuring his artwork.
The tracks from Two Steps from Hell are frequently used in film trailers and other promotional materials.
Sun is an R&B, soul, disco, and funk band that was formed in the mid-1970s and recorded prolifically for Capitol Records from 1976 to 1984. The band was founded by Byron Byrd in Dayton, Ohio, in 1976. Additional members included Kym Yancey, Chris Jones, John Wagner, Hollis Melson, and Shawn Sandridge.
After being signed to Capitol by Larkin Arnold, Sun was faced with an immediate problem: an incomplete band. The black hole was in the rhythm section, so Byron Byrd recruited Roger Troutman and Lester Troutman (now with Zapp) and paid them to do some studio sessions so he could get the album finished. Lester laid drum tracks with Roger on bass, then Roger overdubbed guitar for four songs on the album, including "Live On, Dream On." But it was on "Wanna Make Love (Come Flick My BIC)". Roger Troutman died April 25, 1999.
As the first single from the debut LP, Live On, Dream On (1976), "Wanna Make Love" became Sun's first hit, peaking at #31 on Billboard’s R&B chart.
With the release of their second album, Sun Power (pressed on orange vinyl in 1977), Sun sprang into a ten-piece configuration of multi-instrumentalists and vocalists that consisted of Byron Byrd, John Hampton Wagner, Christopher D. Jones, Hollis Melson, Dean Hummons, Kym Yancey, Shawn Sandridge, Bruce Hastell, Gary King and Ernie Knisley. The album also contained “Conscience,” the song "Time Is Passing” (used and sampled many Rap Artists including Dr. Dre) plus the instrumental “We’re So Hot,” which has been used in sports telecasts.
The Distance to Here is the fourth studio album by the band Live, released in 1999. It debuted at #4 on the Billboard 200, selling 138,000 copies in its first week and was certified Platinum by the RIAA on November 19, 1999.

In mathematics, and more specifically in abstract algebra, a *-algebra (or involutive algebra) is a mathematical structure consisting of two involutive rings R and A, where R is commutative and A has the structure of an associative algebra over R. Involutive algebras generalize the idea of a number system equipped with conjugation, for example the complex numbers and complex conjugation, matrices over the complex numbers and conjugate transpose, and linear operators over a Hilbert space and Hermitian adjoints.
In mathematics, a *-ring is a ring with a map * : A → A that is an antiautomorphism and an involution.
More precisely, * is required to satisfy the following properties:
for all x, y in A.
This is also called an involutive ring, involutory ring, and ring with involution. Note that the third axiom is actually redundant, because the second and fourth axioms imply 1* is also a multiplicative identity, and identities are unique.
A ringtone or ring tone is the sound made by a telephone to indicate an incoming call or text message. Not literally a tone nor an actual (bell-like) ring any more, the term is most often used today to refer to customizable sounds used on mobile phones.
A phone “rings” when its network indicates an incoming call and the phone thus alerts the recipient. For landline telephones, the call signal can be an electric current generated by the switch or exchange to which the telephone is connected, which originally drove an electric bell. For mobile phones, the network sends the phone a message indicating an incoming call. The sound the caller hears is called the ringback tone, which is not necessarily directly related.
The electromagnetic bell system is still in widespread use. The ringing signal sent to a customer's telephone is 90 volts AC at a frequency of 20 hertz in North America. In Europe it is around 60-90 volts AC at a frequency of 25 hertz. Some non-Bell Company system party lines in the US used multiple frequencies (20/30/40 Hz, 22/33/44 Hz, etc.) to allow "selective" ringing.
In mathematics, a nonempty collection of sets is called a σ-ring (pronounced sigma-ring) if it is closed under countable union and relative complementation.
Let be a nonempty collection of sets. Then
is a σ-ring if:
From these two properties we immediately see that
This is simply because .
If the first property is weakened to closure under finite union (i.e., whenever
) but not countable union, then
is a ring but not a σ-ring.
σ-rings can be used instead of σ-fields (σ-algebras) in the development of measure and integration theory, if one does not wish to require that the universal set be measurable. Every σ-field is also a σ-ring, but a σ-ring need not be a σ-field.
A σ-ring that is a collection of subsets of
induces a σ-field for
. Define
to be the collection of all subsets of

. In fact

A leaf is an organ of a vascular plant and is the principal lateral appendage of the stem. The leaves and stem together form the shoot.Foliage is a mass noun that refers to leaves collectively.
Typically a leaf is a thin, dorsiventrally flattened organ, borne above ground and specialized for photosynthesis. Most leaves have distinctive upper (adaxial) and lower (abaxial) surfaces that differ in colour, hairiness, the number of stomata (pores that intake and output gases) and other features. In most plant species, leaves are broad and flat. Such species are referred to as broad-leaved plants. Many gymnosperm species have thin needle-like leaves that can be advantageous in cold climates frequented by snow and frost. Leaves can also have other shapes and forms such as the scales in certain species of conifers. Some leaves are not above ground (such as bulb scales). Succulent plants often have thick juicy leaves, but some leaves are without major photosynthetic function and may be dead at maturity, as in some cataphylls, and spines). Furthermore, several kinds of leaf-like structures found in vascular plants are not totally homologous with them. Examples include flattened plant stems (called phylloclades and cladodes), and phyllodes (flattened leaf stems), both of which differ from leaves in their structure and origin. Many structures of non-vascular plants, and even of some lichens, which are not plants at all (in the sense of being members of the kingdom Plantae), look and function much like leaves. The primary site of photosynthesis in most leaves (palisade mesophyll) almost always occurs on the upper side of the blade or lamina of the leaf but in some species, including the mature foliage of Eucalyptus palisade occurs on both sides and the leaves are said to be isobilateral.
