Majlis
Majlis, Mejlis (Arabic: مجلس, pl. مجالس Majālis), or Majles (Persian: مجلس‎) is an Arabic and Persian term meaning "council", used to describe various types of special gatherings among common interest groups be it administrative, social or religious in countries with linguistic or cultural connections to Islamic countries. The Majlis can refer to a legislature as well and is used in the name of legislative councils or assemblies in some of the states where Islamic culture dominates. The term Majlis is also used to refer to a private place (a lounge, or 'salon' in British English and French, or 'saloon' on a ship) where guests are received and entertained.

Documentation of Cultural Property
The documentation of cultural property is a critical aspect of collections care. As stewards of cultural property, museums collect and preserve not only objects but the research and documentation connected to those objects, in order to more effectively care for them. Documenting cultural heritage is a collaborative effort. Essentially, registrars, collection managers, conservators, and curators all contribute to the task of recording and preserving information regarding collections. There are two main types of documentation museums are responsible for: records generated in the registration process—accessions, loans, inventories, etc. and information regarding research on objects and their historical significance. Properly maintaining both types of documentation is vital to preserving cultural heritage.

FYFT G-Series Unmanned Blimp
FYFT G-series unmanned blimps are Chinese UAVs developed by Qingdao Co., Ltd. Fei-Yu (meaning Flying Universe) Aviation Science and Technology Co., Ltd. (FYFT, 青岛飞宇有限公司), and these unmanned blimps are named after their respective length. For example: if an G1 series blimp is 11 meter long, then it is named G1-1100, because 11 meter is equal to 1100 millimeter. The letter G stands for General (purpose).

Harvard Medical African Expedition (1926-1927)
The Harvard Medical African Expedition of 1926-1927 was an eight-man venture sent by Harvard University for the primary purpose of conducting a medical and biological survey of Liberia; the secondary purpose being to then cross Africa from coast to coast - west to east - through the Belgian Congo (and other regions) so as to make a comparative study of their Liberian findings. Furthermore, the Liberian interior was next of kin to being terra incognita in the West, there having been no previous medical or scientific survey of the region, nor any recorded expedition into the Liberian hinterlands. The Expedition leader was Richard Pearson Strong (Harvard's first Professor of tropical medicine), with the others being zoologists Harold Jefferson Coolidge Jr. (Assistant Curator of Mammals at Harvard) and Dr. Glover Morrill Allen, entomologist Dr. Joseph Charles Bequaert, botanist and Washington University Professor David H. Linder, bacteriologist Dr. George C. Shattuck, bacteriologist Dr. Max Theiler, and Assistant Ornithologist Loring Whitman (also a Harvard medical student and the Photographer). The Expedition was a success and, while its "chief objective was the investigation of tropical diseases, many zoological specimens were collected and the customs of the native tribes were studied." The story of their travels back and forth across Liberia, and reports of the diseases found that ailed the inhabitants, animals and plants was published in the two-volume The African Republic of Liberia and the Belgian Congo: Based on the Observations Made and Material Collected during the Harvard African Expedition, 1926-1927 written by Dr. Strong in a partnership with other Expedition members and Harvard officials.

Limit Point
In mathematics, a limit point (or cluster point or accumulation point) of a set [math]\displaystyle{ S }[/math] in a topological space [math]\displaystyle{ X }[/math] is a point [math]\displaystyle{ x }[/math] that can be "approximated" by points of [math]\displaystyle{ S }[/math] in the sense that every neighbourhood of [math]\displaystyle{ x }[/math] with respect to the topology on [math]\displaystyle{ X }[/math] also contains a point of [math]\displaystyle{ S }[/math] other than [math]\displaystyle{ x }[/math] itself. A limit point of a set [math]\displaystyle{ S }[/math] does not itself have to be an element of [math]\displaystyle{ S. }[/math] There is also a closely related concept for sequences. A cluster point or accumulation point of a sequence [math]\displaystyle{ (x_n)_{n \in \mathbb{N}} }[/math] in a topological space [math]\displaystyle{ X }[/math] is a point [math]\displaystyle{ x }[/math] such that, for every neighbourhood [math]\displaystyle{ V }[/math] of [math]\displaystyle{ x, }[/math] there are infinitely many natural numbers [math]\displaystyle{ n }[/math] such that [math]\displaystyle{ x_n \in V. }[/math] This definition of a cluster or accumulation point of a sequence generalizes to nets and filters. In contrast to sets, for a sequence, net, or filter, the term "limit point" is not synonymous with a "cluster/accumulation point"; by definition, the similarly named notion of a limit point of a filter (respectively, a limit point of a sequence, a limit point of a net) refers to a point that the filter converges to (respectively, the sequence converges to, the net converges to). The limit points of a set should not be confused with adherent points for which every neighbourhood of [math]\displaystyle{ x }[/math] contains a point of [math]\displaystyle{ S }[/math]. Unlike for limit points, this point of [math]\displaystyle{ S }[/math] may be [math]\displaystyle{ x }[/math] itself. A limit point can be characterized as an adherent point that is not an isolated point. Limit points of a set should also not be confused with boundary points. For example, [math]\displaystyle{ 0 }[/math] is a boundary point (but not a limit point) of set [math]\displaystyle{ \{ 0 \} }[/math] in [math]\displaystyle{ \R }[/math] with standard topology. However, [math]\displaystyle{ 0.5 }[/math] is a limit point (though not a boundary point) of interval [math]\displaystyle{ [0, 1] }[/math] in [math]\displaystyle{ \R }[/math] with standard topology (for a less trivial example of a limit point, see the first caption). This concept profitably generalizes the notion of a limit and is the underpinning of concepts such as closed set and topological closure. Indeed, a set is closed if and only if it contains all of its limit points, and the topological closure operation can be thought of as an operation that enriches a set by uniting it with its limit points.

Solvency II Directive 2009
The Solvency II Directive (2009/138/EC) is a Directive in European Union law that codifies and harmonises the EU insurance regulation. Primarily this concerns the amount of capital that EU insurance companies must hold to reduce the risk of insolvency. Following an EU Parliament vote on the Omnibus II Directive on 11 March 2014, Solvency II came into effect on 1 January 2016. This date had been previously pushed back many times.

Polarization (Politics)
Template:Globalize/US In politics, polarization (or polarisation) can refer to the divergence of political attitudes to ideological extremes. Almost all discussions of polarization in political science consider polarization in the context of political parties and democratic systems of government. When polarization occurs in a two-party system, like the United States , moderate voices often lose power and influence.

ID-Based Encryption
ID-based encryption, or identity-based encryption (IBE), is an important primitive of ID-based cryptography. As such it is a type of public-key encryption in which the public key of a user is some unique information about the identity of the user (e.g. a user's email address). This means that a sender who has access to the public parameters of the system can encrypt a message using e.g. the text-value of the receiver's name or email address as a key. The receiver obtains its decryption key from a central authority, which needs to be trusted as it generates secret keys for every user. ID-based encryption was proposed by Adi Shamir in 1984. He was however only able to give an instantiation of identity-based signatures. Identity-based encryption remained an open problem for many years. The pairing-based Boneh–Franklin scheme and Cocks's encryption scheme based on quadratic residues both solved the IBE problem in 2001.
