List Of Active United States Marine Corps Aircraft Squadrons
This is a list of all of the active Squadron (aviation), squadrons that exist in the United States Marine Corps, sorted by type. Most squadrons have changed names and designations many times over the years, so they are listed by their current designation. :''To see United States Marine Corps Aviation, Marine Aviation units sorted by command hierarchy, see Aviation combat element#Hierarchy of Marine Aviation units, aviation combat element.'' Squadron designations The basic tactical and administrative unit of United States Marine Corps aviation is the squadron. Fixed-wing aircraft squadrons (heavier than air) and tiltrotor squadrons are denoted by the letter "V", which comes from the Spanish verb "volar" (to fly). Rotorcraft, Rotary wing (helicopter) squadrons use "H." Marine squadrons are always noted by the second letter "M." Squadron numbering is not linear as some were numbered in ascending order and others took numbers from the wing or the ship to which they were assigned. Fr ...

Ventromedial Prefrontal Cortex
The ventromedial prefrontal cortex (vmPFC) is a part of the prefrontal cortex in the mammalian brain. The ventral medial prefrontal is located in the frontal lobe at the bottom of the cerebral hemispheres and is implicated in the processing of risk and fear, as it is critical in the regulation of amygdala activity in humans. It also plays a role in the inhibition of emotional responses, and in the process of decision-making and self-control. It is also involved in the cognitive evaluation of morality. Anatomy While the ventromedial prefrontal cortex does not have a universally agreed on demarcation, in most sources, it is equivalent to the ventromedial reward network of Öngür and Price. This network includes Brodmann area 10, Brodmann area 14, Brodmann area 25, and Brodmann area 32, as well as portions of Brodmann area 11, Brodmann area 12, and Brodmann area 13. However, not all sources agree on the boundaries of the area. Different researchers use the term ''ventromedial pref ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

VM Motori
VM Motori S.p.A. is an Italian diesel engine manufacturing company which is wholly owned by Stellantis. VM headquarters and main production facilities are located in Cento, in Emilia-Romagna, Italy. History VM Motori was founded by two entrepreneurs, Claudio Vancini and Ugo Martelli (hence the ''"VM"'') in 1947. VM merged with ''Stabilimenti Meccanici Triestini'' in Trieste in 1971, then ''Finmeccanica'' took a majority stake in the combined company. The company was referred to as "Finmeccanica VM" for many years. In 1989, Finmeccanica restructured, selling its stake in VM Motori to company managers and Midland Montague in a leveraged buyout, leaving the company with its single Cento plant. Detroit Diesel Corporation (DDC) bought VM Motori in 1995. In 2000, DDC was purchased by DaimlerChrysler AG. In 2003, Penske Corporation purchased a 51% stake in VM Motori; in 2007, Penske bought the remaining 49% from Detroit Diesel Corporation and subsequently sold 50% of it to Gene ...

Virtual Memory
In computing, virtual memory, or virtual storage is a memory management technique that provides an "idealized abstraction of the storage resources that are actually available on a given machine" which "creates the illusion to users of a very large (main) memory". The computer's operating system, using a combination of hardware and software, maps memory addresses used by a program, called '' virtual addresses'', into ''physical addresses'' in computer memory. Main storage, as seen by a process or task, appears as a contiguous address space or collection of contiguous segments. The operating system manages virtual address spaces and the assignment of real memory to virtual memory. Address translation hardware in the CPU, often referred to as a memory management unit (MMU), automatically translates virtual addresses to physical addresses. Software within the operating system may extend these capabilities, utilizing, e.g., disk storage, to provide a virtual address space that ca ...

Virtual Machine
In computing, a virtual machine (VM) is the virtualization/emulation of a computer system. Virtual machines are based on computer architectures and provide functionality of a physical computer. Their implementations may involve specialized hardware, software, or a combination. Virtual machines differ and are organized by their function, shown here: * '' System virtual machines'' (also termed full virtualization VMs) provide a substitute for a real machine. They provide functionality needed to execute entire operating systems. A hypervisor uses native execution to share and manage hardware, allowing for multiple environments which are isolated from one another, yet exist on the same physical machine. Modern hypervisors use hardware-assisted virtualization, virtualization-specific hardware, primarily from the host CPUs. * Process virtual machines are designed to execute computer programs in a platform-independent environment. Some virtual machine emulators, such as QEMU and video ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Voicemail
A voicemail system (also known as voice message or voice bank) is a computer-based system that allows users and subscribers to exchange personal voice messages; to select and deliver voice information; and to process transactions relating to individuals, organizations, products, and services, using an ordinary phone. The term is also used more broadly to denote any system of conveying a stored telecommunications voice messages, including using an answering machine. Most cell phone services offer voicemail as a basic feature; many corporate private branch exchanges include versatile internal voice-messaging services, and *98 vertical service code subscription is available to most individual and small business landline subscribers (in the US).

Virtuti Militari
The War Order of Virtuti Militari (Latin: ''"For Military Virtue"'', pl, Order Wojenny Virtuti Militari) is Poland's highest military decoration for heroism and courage in the face of the enemy at war. It was created in 1792 by Polish King Stanislaus II Augustus and is the oldest military decoration in the world still in use. It is awarded in five classes either for personal heroism or, to commanders, for leadership. Some of the heroic actions recognized by an award of the Virtuti Militari are equivalent to those meriting the British Victoria Cross, the German Iron Cross, and the American Medal of Honor. Soon after its introduction, however, the Polish–Lithuanian Commonwealth was destroyed in the partitions of Poland (1795), and the partitioning powers abolished the decoration and prohibited its wearing. Since then, the award has been reintroduced, renamed and banned several times, with its fate closely reflecting the vicissitudes of the Polish people. Throughout the decorat ...
