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.

Top

A top is a toy designed to be spun rapidly on the ground, the motion of which causes it to remain precisely balanced on its tip because of inertia. Such toys have existed since antiquity. Traditionally tops were constructed of wood, sometimes with an iron tip, and would be set in motion by aid of a string or rope coiled around its axis which, when pulled quickly, caused a rapid unwinding that would set the top in motion. Today they are often built of plastic, and modern materials and manufacturing processes allow tops to be constructed with such precise balance that they can be set in motion by a simple twist of the fingers and twirl of the wrist without need for string or rope.

Characteristics

The motion of a top is produced in the most simple forms by twirling the stem using the fingers. More sophisticated tops are spun by holding the axis firmly while pulling a string or twisting a stick or pushing an auger. In the kinds with an auger, an internal weight rotates, producing an overall circular motion. Some tops can be thrown, while firmly grasping a string that had been tightly wound around the stem, and the centrifugal force generated by the unwinding motion of the string will set them spinning upon touching ground.

Top (clothing)

A top is clothing that covers at least the chest, but which usually covers most of the upper human body between the neck and the waistline. The bottom of tops can be as short as mid-torso, or as long as mid-thigh. Men's tops are generally paired with pants, and women's with pants or skirts. Common types of tops are t-shirts, blouses and shirts.

Design

The neckline is the highest line of the top, and may be as high as a head-covering hood, or as low as the waistline or bottom hem of the top. A top may be worn loose or tight around the bust or waist, and may have sleeves or shoulder straps, spaghetti straps (noodle straps), or may be strapless. The back may be covered or bare. Tops may have straps around the waist or neck, or over the shoulders.

Category of topological spaces

In mathematics, the category of topological spaces, often denoted Top, is the category whose objects are topological spaces and whose morphisms are continuous maps or some other variant; for example, objects are often assumed to be compactly generated. This is a category because the composition of two continuous maps is again continuous. The study of Top and of properties of topological spaces using the techniques of category theory is known as categorical topology.

N.B. Some authors use the name Top for the category with topological manifolds as objects and continuous maps as morphisms.

As a concrete category

Like many categories, the category Top is a concrete category (also known as a construct), meaning its objects are sets with additional structure (i.e. topologies) and its morphisms are functions preserving this structure. There is a natural forgetful functor

to the category of sets which assigns to each topological space the underlying set and to each continuous map the underlying function.

Best! (Jellyfish album)

Best! is a greatest hits compilation by the 1990s pop band Jellyfish. The album was released in 2006 and featured twenty tracks. Eight of the tracks were non-album while the other twelve consisted of songs pulled from the band's two (and only) albums, Bellybutton and Spilt Milk. The song "Ignorance is Bliss" was taken from a Nintendo games compilation entitled "Nintendo: White Knuckle Scorin'" and is inspired by the video game Super Mario World. The song "No Matter What" is a live cover of a Badfinger song.
