Clover

Clover or trefoil are common names for plants of the genus Trifolium (Latin, tres "three" + folium "leaf"), consisting of about 300 species of plants in the leguminous pea family Fabaceae. The genus has a cosmopolitan distribution; the highest diversity is found in the temperate Northern Hemisphere, but many species also occur in South America and Africa, including at high altitudes on mountains in the tropics. They are small annual, biennial, or short-lived perennial herbaceous plants. The leaves are trifoliate (rarely quatrefoiled, cinquefoil, or septfoil), with stipules adnate to the leaf-stalk, and heads or dense spikes of small red, purple, white, or yellow flowers; the small, few-seeded pods are enclosed in the calyx. Other closely related genera often called clovers include Melilotus (sweet clover) and Medicago (alfalfa or 'cavalry clover').

Cultivation

Several species of clover are extensively cultivated as fodder plants. The most widely cultivated clovers are white clover Trifolium repens and crimson clover Trifolium pratense. Clover, either sown alone or in mixture with ryegrass, has for a long time formed a staple crop for silaging, for several reasons: it grows freely, shooting up again after repeated mowings; it produces an abundant crop; it is palatable to and nutritious for livestock; it fixes nitrogen, reducing the need for synthetic fertilizers; it grows in a great range of soils and climates; and it is appropriate for either pasturage or green composting.

Clover (band)

Clover was an American country rock band formed in Mill Valley, California, in 1967. They are best known as the backup band for Elvis Costello's 1977 debut album My Aim Is True (recorded in the UK), and for members later forming or joining more successful acts, including Huey Lewis and the News, The Doobie Brothers, Toto, and Lucinda Williams. Clover disbanded in 1978. Three members reunited for two concerts backing Costello in San Francisco on November 8, 2007.

History

Formed by members of the band Tiny Hearing Aid Company, Clover's sound moved on from Bay Area psychedelia to the burgeoning country rock sound, similar to Creedence Clearwater Revival. 1970 saw their debut self-titled album released on Fantasy Records (also Creedence's label), and a 1971 follow-up entitled Fourty Niner [sic]. Later the band moved to the UK and recorded Unavailable and Love on the Wire (both in 1977 and early efforts by producer Robert John "Mutt" Lange), before McFee, Ciambotti, Hopper and Shine backed Elvis Costello on his debut album My Aim Is True. Clover toured as the support group for Thin Lizzy in the UK during the late 1970s.

Smooth (iiO song)

"Smooth" is the third single released from iiO's debut album, Poetica.

Gerald Albright

Gerald Albright (born August 30, 1957) is an American jazz saxophonist and multi-instrumentalist.

Albright has sold over 1,000,000 albums in the U.S. alone. His self-produced music features him on bass guitar, keyboards, flutes, drum programming, and background vocals.

Biography

Born in Los Angeles, Albright grew up in its South Central neighborhood. He began piano lessons at an early age, even though he professed no great interest in the instrument. His love of music picked up considerably when he was given a saxophone that belonged to his piano teacher. It was further reinforced when he attended Locke High School, a breeding ground for many young West Coast musicians. After high school, he attended the University of Redlands where he received a B.S. degree in business management, minoring in music. Already a polished saxophonist by the time he enrolled in college, Albright suddenly switched to bass guitar after he saw Louis Johnson in concert.

Immediately after college, Albright began to master his talent by working extensively in the studio with such artists as Anita Baker, Ray Parker, Jr., The Temptations and Olivia Newton-John. A few months after graduating from college, Gerald joined Patrice Rushen, who was in the process of forming her own band, in which he played the saxophone. Later, when the bass player left in the middle of a tour, Albright replaced him and finished the tour on bass guitar. Consequently, he often performed on both instruments. Around the same time, he also began to tour Europe with drummer Alphonse Mouzon.

Smooth number

In number theory, a smooth (or friable) number is an integer which factors completely into small prime numbers. The term seems to have been coined by Leonard Adleman. Smooth numbers are especially important in cryptography relying on factorization. The 2-smooth numbers are just the powers of 2.

Definition

A positive integer is called B-smooth if none of its prime factors is greater than B. For example, 1,620 has prime factorization 2² × 3⁴ × 5; therefore 1,620 is 5-smooth because none of its prime factors are greater than 5. This definition includes numbers that lack some of the smaller prime factors; for example, both 10 and 12 are 5-smooth, despite the fact that they miss out prime factors 3 and 5 respectively. 5-smooth numbers are also called regular numbers or Hamming numbers; 7-smooth numbers are also called humble, and sometimes called highly composite, although this conflicts with another meaning of highly composite numbers.

Note that B does not have to be a prime factor. If the largest prime factor of a number is p then the number is B-smooth for any B ≥ p. Usually B is given as a prime, but composite numbers work as well. A number is B-smooth if and only if it is p-smooth, where p is the largest prime less than or equal to B.
