Advanced air mobility (AAM) are systems that incorporate support for next-generation transport such as such as remotely piloted, autonomous, or vertical take-off and landing (VTOL) aircraft. [1] [2] [3] This includes those powered by electric or hybrid-electric propulsion. [4] AAM seeks to support unmanned aerial systems (UAS) and sustainable ...
Urban air mobility is a subset of a broader advanced air mobility (AAM) concept that includes other use cases than intracity passenger transport; [1] NASA describes advanced air mobility as including small drones, electric aircraft, and automated air traffic management among other technologies to perform a wide variety of missions including ...
The National Advanced Air Mobility Center of Excellence is a research facility dedicated to studying air mobility and Unmanned Aircraft Systems (UAS). It contains 30,000 square feet of administrative, laboratory, meeting, and collaboration space with an additional 25,000 square feet of aircraft hangar space.
A biomolecule or biological molecule is loosely defined as a molecule produced by a living organism and essential to one or more typically biological processes. [1] Biomolecules include large macromolecules such as proteins , carbohydrates , lipids , and nucleic acids , as well as small molecules such as vitamins and hormones.
Gliding motility is a type of translocation used by microorganisms that is independent of propulsive structures such as flagella, pili, and fimbriae. [1] Gliding allows microorganisms to travel along the surface of low aqueous films. The mechanisms of this motility are only partially known.
Motility differs from mobility, the ability of an object to be moved. The term vagility means a lifeform that can be moved but only passively; sessile organisms including plants and fungi often have vagile parts such as fruits, seeds, or spores which may be dispersed by other agents such as wind, water, or other organisms.
High-Mobility Group or HMG is a group of chromosomal proteins that are involved in the regulation of DNA-dependent processes such as transcription, replication, recombination, and DNA repair. [ 1 ] History and name
Cross-sectional view of the structures that can be formed by phospholipids in an aqueous solution. A biological membrane, biomembrane or cell membrane is a selectively permeable membrane that separates the interior of a cell from the external environment or creates intracellular compartments by serving as a boundary between one part of the cell and another.
