A home, or domicile, is a space used as a permanent or semi-permanent residence for one or more human occupants, and sometimes various companion animals. It is a fully- or semi-sheltered space and can have both interior and exterior aspects to it. Homes provide sheltered spaces, for instance rooms, where domestic activity can be performed such as sleeping, preparing food, eating and hygiene as well as providing spaces for work and leisure such as remote working, studying and playing.

Physical forms of homes can be static such as a house or an apartment, mobile such as a houseboat, trailer or yurt or digital such as virtual space. The aspect of 'home' can be considered across scales; from the micro scale showcasing the most intimate spaces of the individual dwelling and direct surrounding area to the macro scale of the geographic area such as town, village, city, country or planet.

The concept of 'home' has been researched and theorized across disciplines – topics ranging from the idea of home, the interior, the psyche, liminal space, contested space to gender and politics. The home as a concept expands beyond residence as contemporary lifestyles and technological advances redefine the way the global population lives and works. The concept and experience encompasses the likes of exile, yearning, belonging, homesickness and homelessness.

Laboratory Corporation of America Holdings (Labcorp), headquartered in Burlington, North Carolina, provides laboratory services used for diagnosis and healthcare decisions. It operates one of the largest clinical laboratory networks in the world and has operations in over 100 countries; although its operations are primarily in the U.S.

Its Diagnostics Laboratories segment operates 2,000 patient service centers (PSCs) with more than 6,000 in-office phlebotomists in the United States. In addition to healthcare testing such as oncology testing, human immunodeficiency virus (HIV) genotyping and phenotyping, it provides testing for: employment, DNA testing to determine parentage and to determine immigration eligibility, environmental issues, wellness, toxicology, pain management, and medical drug monitoring. It also provides 50 tests that patients can complete at home. It processes over 160 million tests per year. Approximately 10% of the division's revenue are from Medicare.

Its Biopharma Laboratory Services segment provides drug development, medical device and diagnostic development services to pharmaceutical, biotechnology, medical device, and diagnostic companies. In 2023, this division provided support to 84% of the new drugs and therapeutic products approved by the Food and Drug Administration.

Labcorp performs its largest volume of specialty testing at its Center for Esoteric Testing in Burlington, North Carolina.

Labcorp was an early pioneer of genomic testing using polymerase chain reaction (PCR) technology at its Center for Molecular Biology and Pathology in Research Triangle Park, North Carolina, where it also performs other molecular diagnostics. Labcorp operates the National Genetics Institute, Inc. (NGI), in Los Angeles, California, which develops PCR testing methods.

In digital imaging, a pixel (abbreviated px), pel, or picture element is the smallest addressable element in a raster image, or the smallest addressable element in a dot matrix display device. In most digital display devices, pixels are the smallest element that can be manipulated through software.

Each pixel is a sample of an original image; more samples typically provide more accurate representations of the original. The intensity of each pixel is variable. In color imaging systems, a color is typically represented by three or four component intensities such as red, green, and blue, or cyan, magenta, yellow, and black.

In some contexts (such as descriptions of camera sensors), pixel refers to a single scalar element of a multi-component representation (called a photosite in the camera sensor context, although sensel 'sensor element' is sometimes used), while in yet other contexts (like MRI) it may refer to a set of component intensities for a spatial position.

Software on early consumer computers was necessarily rendered at a low resolution, with large pixels visible to the naked eye; graphics made under these limitations may be called pixel art, especially in reference to video games. Modern computers and displays, however, can easily render orders of magnitude more pixels than was previously possible, necessitating the use of large measurements like the megapixel (one million pixels).

Test(s), testing, or TEST may refer to:

• Test (assessment), an educational assessment intended to measure the respondents' knowledge or other abilities
