Sport utility vehicle

A sport utility vehicle (SUV, sometimes called a sports utility wagon) is a vehicle similar to a station wagon or estate car that is usually equipped with four-wheel drive for on-road or off-road ability. Some SUVs include the towing capacity of a pickup truck with the passenger-carrying space of a minivan or large sedan.

Definitions

According to the Merriam-Webster dictionary, a "sport utility vehicle" is "a rugged automotive vehicle similar to a station wagon but built on a light-truck chassis". The "SUV" term is defined as "a large vehicle that is designed to be used on rough surfaces but that is often used on city roads or highways." The "SUV" acronym "is still used to describe nearly anything with available all-wheel drive and raised ground clearance."

North America

There are a number of definitions for an SUV. Most government regulations simply have categories for "off-highway vehicles," which in turn are lumped in with pickup trucks and minivans as light trucks." The auto industry has not settled on one definition.

Standardized uptake value

The standardized uptake value (SUV) is often used in positron emission tomography (PET) imaging for a (semi)quantitative analysis. Its use is particularly common in the analysis of [¹⁸F]fluorodeoxyglucose ([¹⁸F]FDG) images of cancer patients. It can also be used with other PET agents especially when no arterial input function is available for more detailed pharmacokinetic modeling. Otherwise measures like the fractional uptake rate (FUR) or parameters from more advanced pharmacokinetic modeling may be preferable.

The SUV is the ratio of the image derived radioactivity concentration c_img and the whole body concentration of the injected radioactivity c_inj,

While this equation looks simple, there are a number of details that need to be discussed, such as (1) the origin of c_img data, (2) the origin of c_inj data, (3) time, and (4) units.

The c_img data may be the pixel intensities of a calibrated PET image. Calculated SUV data can then be visualized as parametric SUV image. Alternatively, groups of such pixels may be selected e.g. by manually drawing or otherwise segmenting a region of interest (ROI) on the PET image. Then e.g. the average intensity of that ROI may be used as c_img input to calculate SUVs.

Intro (R&B group)

Intro is an American R&B trio from Brooklyn, New York City, New York. The trio consisted of members Jeff Sanders, Clinton "Buddy" Wike and lead singer/songwriter Kenny Greene. Intro released two albums (for Atlantic Records): 1993's Intro and their second album, 1995's New Life. The group had a string of US hits in the 1990s. The hits included the singles "Let Me Be The One", the Stevie Wonder cover "Ribbon in the Sky", "Funny How Time Flies" and their highest charting hit, "Come Inside".

Intro's Kenny Greene died from complications of AIDS in 2001. Intro recently emerged as a quintet consisting of Clinton "Buddy" Wike, Jeff Sanders, Ramon Adams and Eric Pruitt. Adams departed in 2014, with the group back down to its lineup as a trio. They are currently recording a new album to be released in 2015. The group released a new single in 2013 called "I Didn't Sleep With Her" and a new single "Lucky" in October 2014.

Introduction (music)

In music, the introduction is a passage or section which opens a movement or a separate piece, preceding the theme or lyrics. In popular music this is often abbreviated as intro. The introduction establishes melodic, harmonic, and/or rhythmic material related to the main body of a piece.

Introductions may consist of an ostinato that is used in the following music, an important chord or progression that establishes the tonality and groove for the following music, or they may be important but disguised or out-of-context motivic or thematic material. As such the introduction may be the first statement of primary or other important material, may be related to but different from the primary or other important material, or may bear little relation to any other material.

A common introduction to a rubato ballad is a dominant seventh chord with fermata, Play  an introduction that works for many songs is the last four or eight measures of the song, Play  while a common introduction to the twelve-bar blues is a single chorus. Play
