State Policy Network
The State Policy Network (SPN) is a nonprofit organization that serves as a network for conservative and libertarian think tanks focusing on state-level policy in the United States. The network serves as a public policy clearinghouse and advises its member think tanks on fundraising, running a nonprofit, and communicating ideas. Founded in 1992, it is headquartered in Arlington, Virginia, with member groups located in all fifty states. Overview SPN describes itself as a "professional service organization" for a network of state-level think tanks across the United States. The president of SPN is Tracie Sharp, formerly the executive director of the Cascade Policy Institute, SPN's Oregon affiliate. She has described her organizing philosophy as "the IKEA model", because like a ready-to-assemble furniture retailer, the network offers a catalog of policy projects that state-level groups can build. History The State Policy Network was founded in 1992 by Thomas A. Roe, a South Carolin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Serbia Against Violence (coalition)
Serbia Against Violence ( sr-Cyrl, Србија против насиља, Srbija protiv nasilja, abbr. SPN) is an opposition coalition of political parties in Serbia. Formalised in October 2023, SPN took part in the parliamentary, Vojvodina provincial, Belgrade City Assembly elections and elections for city assemblies in other cities, all of which were held on 17 December 2023. The SPN was formed out of the Serbia Against Violence protests that began after the Belgrade elementary school and Mladenovac and Smederevo mass shootings in May 2023. The cooperation between the parties organising the protests increased during the protests, leading them to create a coalition. Marinika Tepić and Miroslav Aleksić were announced as the representatives for the parliamentary election while Vladimir Obradović and Dobrica Veselinović were announced as the representatives for the Belgrade City Assembly election. In the parliamentary election, SPN ended up winning 65 seats in the Natio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Saipan International Airport
Saipan International Airport , also known as Francisco C. Ada/Saipan International Airport, is a public airport located on Saipan Island in the United States Commonwealth of the Northern Mariana Islands. The airport is owned by Commonwealth Ports Authority. Its airfield was previously known as Aslito (during the Japanese South Seas Mandate) and Isely Field (during the American World War II and later period). This airport is assigned a three-letter location identifier of GSN by the Federal Aviation Administration, but the International Air Transport Association (IATA) airport code is SPN (the IATA assigned GSN to Mount Gunson Airport in Australia). History World War II Saipan International Airport was a sugarcane field before the Imperial Japanese Navy Air Service (IJNAS) constructed a temporary landing field on the site in 1933. The landing field was used for training purposes and had two runways configured in an "L" pattern. In 1937, the Navy began upgrading the airfield for ...

Scientific Pitch Notation
Scientific pitch notation (SPN), also known as American standard pitch notation (ASPN) and international pitch notation (IPN), is a method of specifying musical Pitch (music), pitch by combining a musical Note (music), note name (with accidental (music), accidental if needed) and a number identifying the pitch's octave. Although scientific pitch notation was originally designed as a companion to scientific pitch (see below), the two are not synonymous. Scientific pitch is a pitch standard—a system that defines the specific frequencies of particular pitches (see below). Scientific pitch notation concerns only how pitch names are notated, that is, how they are designated in printed and written text, and does not inherently specify actual frequencies. Thus, the use of scientific pitch notation to distinguish octaves does not depend on the pitch standard used. Nomenclature The notation makes use of the traditional tone names (A to G) which are followed by numbers showing which octa ...

Savanna Pastoral Neolithic
The Savanna Pastoral Neolithic (SPN; formerly known as the Stone Bowl Culture) is a collection of ancient societies that appeared in the Rift Valley of East Africa and surrounding areas during a time period known as the Pastoral Neolithic. They were South Cushitic speaking pastoralists who tended to bury their dead in cairns, whilst their toolkit was characterized by stone bowls, pestles, grindstones and earthenware pots. Through archaeology, historical linguistics and archaeogenetics, they conventionally have been identified with the area's first Afroasiatic-speaking settlers. Archaeological dating of livestock bones and burial cairns has also established the cultural complex as the earliest center of pastoralism and stone construction in the region. Overview The makers of the Savanna Pastoral Neolithic culture are believed to have arrived in the Rift Valley sometime during the Pastoral Neolithic period (c. 3,000 BCE-700 CE). Through a series of migrations from Horn of Africa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kerberos Protocol
Kerberos () is a computer-network authentication protocol that works on the basis of ''tickets'' to allow nodes communicating over a non-secure network to prove their identity to one another in a secure manner. Its designers aimed it primarily at a client–server model, and it provides mutual authentication—both the user and the server verify each other's identity. Kerberos protocol messages are protected against eavesdropping and replay attacks. Kerberos builds on symmetric-key cryptography and requires a trusted third party, and optionally may use public-key cryptography during certain phases of authentication.RFC 4556, abstract. Kerberos uses UDP port 88 by default. The protocol was named after the character '' Kerberos'' (or ''Cerberus'') from Greek mythology, the ferocious three-headed guard dog of Hades. History and development Massachusetts Institute of Technology (MIT) developed Kerberos in 1988 to protect network services provided by Project Athena. The protocol ...

CD43
Leukosialin also known as sialophorin or CD43 (cluster of differentiation 43) is a transmembrane cell surface protein that in humans is encoded by the ''SPN'' (sialophorin) gene. Function Sialophorin (leukosialin) is a major sialoglycoprotein on the surface of human T lymphocytes, monocytes, granulocytes, and some B lymphocytes, which appears to be important for immune function and may be part of a physiologic ligand-receptor complex involved in T-cell activation. Clinical significance Defects in the CD43 molecule are associated with the development of Wiskott–Aldrich syndrome. It also appears in about 25% of intestinal MALTomas. Using immunohistochemistry, CD43 can be demonstrated in the paracortical T-cells of healthy lymph nodes and tonsils; it is also positive in a range of lymphoid and myeloid tumours. Although it is present in over 90% of T-cell lymphomas, it is generally less effective at demonstrating this condition than is CD3 antigen. However, it may be useful a ...

Solitary Pulmonary Nodule
A lung nodule or pulmonary nodule is a relatively small focal density in the lung. A solitary pulmonary nodule (SPN) or coin lesion, is a mass in the lung smaller than three centimeters in diameter. A pulmonary micronodule has a diameter of less than three millimetres. There may also be multiple nodules. One or more lung nodules can be an incidental finding found in up to 0.2% of chest X-rays and around 1% of CT scans. The nodule most commonly represents a benign tumor such as a granuloma or hamartoma, but in around 20% of cases it represents a malignant cancer, especially in older adults and smokers. Conversely, 10 to 20% of patients with lung cancer are diagnosed in this way. If the patient has a history of smoking or the nodule is growing, the possibility of cancer may need to be excluded through further radiological studies and interventions, possibly including surgical resection. The prognosis depends on the underlying condition. Causes Not every round spot on a radiologi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Spooner Row Railway Station
Spooner Row railway station is on the Breckland line in the East of England, serving the village of Spooner Row, Norfolk. The line runs between in the west and in the east. Spooner Row is situated between and , from London Liverpool Street via . The station is managed by Greater Anglia, which also operates all of the services calling at the station. It is one of the least-used stations in Norfolk, with just 1,344 passenger entries/exits in 2018/19, according to Office of Rail and Road estimates, though this figure was a marked increase on just 264 passengers six years prior. On weekdays, there are two trains per day to Norwich and one to Cambridge, booked to call on request only. In 2020/21, there were 74 passengers. History The Bill for the Norwich & Brandon Railway (N&BR) received Royal Assent on 10 May 1844. The line was to link with an Eastern Counties Railway (ECR) project of a line from Newport in Essex to Brandon in Suffolk. Once complete, the line would enable tra ...

Shortest Job Next
Shortest job next (SJN), also known as shortest job first (SJF) or shortest process next (SPN), is a scheduling policy that selects for execution the waiting process with the smallest execution time. SJN is a non- preemptive algorithm. Shortest remaining time is a preemptive variant of SJN. Shortest job next is advantageous because of its simplicity and because it minimizes the average amount of time each process has to wait until its execution is complete. However, it has the potential for process starvation for processes which will require a long time to complete if short processes are continually added. Highest response ratio next is similar but provides a solution to this problem using a technique called aging. Another disadvantage of using shortest job next is that the total execution time of a job must be known before execution. While it is impossible to predict execution time perfectly, several methods can be used to estimate it, such as a weighted average of previous ...
