TECS, formerly known as the Treasury Enforcement Communications System, is used by the U.S. Department of Homeland Security to manage the flow of people through border ports of entry and for immigration enforcement case management.
 It keeps track of individuals entering and exiting the country and of individuals involved in or suspected to be involved in crimes.
 TECS alerts may be issued as part of Operation Angel Watch for people with sex offense convictions and those who travel frequently out of the country and who are possibly involved in child sex tourism.
The first elections to select inductees to the Baseball Hall of Fame were held in 1936.
 Members of the Baseball Writers' Association of America (BBWAA) were given authority to select individuals from the 20th century; while a special Veterans Committee, made up of individuals with greater familiarity with the 19th century game, was polled to select deserving individuals from that era.
 The intent was for 15 honorees to be selected before the 1939 ceremonies – 10 from the 20th century and 5 from the 19th; additional players from both eras would be selected in later years.
 Voters were given free rein to decide for themselves in which group a candidate belonged, with neither group knowing the outcome of the other election; some candidates had their vote split between the elections as a result – Cy Young, the pitcher with most wins in Major League history, finished 8th in the BBWAA vote and 4th in the Veterans vote.
 In addition, there was no prohibition on voting for active players, a number of whom received votes.
 Individuals who had been banned from baseball – such as Shoeless Joe Jackson and Hal Chase – were also not formally excluded, though few voters chose to include them on ballots.
Martin Bormann (17 June 1900 – 2 May 1945) was a prominent official in Nazi Germany as head of the Nazi Party Chancellery.
 He gained immense power within the Third Reich by using his position as Adolf Hitler's private secretary to control the flow of information and access to Hitler.
The golden-headed lion tamarin ("Leontopithecus chrysomelas"), also the golden-headed tamarin, is a lion tamarin endemic to Brazil.
 It is found only in the lowland and premontane tropical forest fragments in the state of Bahia, and therefore is considered to be an endangered species.
 It lives at heights of 3 - .
 Its preferred habitat is within mature forest, but with habitat destruction this is not always the case.
 Several sources seem to have different information on the number of individuals within a group, and the type of social system that may be apparent.
 The golden-headed lion tamarin lives within group sizes ranging from 2 to 11 individuals, with the average size ranging from 4 to 7.
 According to various sources, the group may consist of two adult males, one adult female, and any immature individuals, one male and one female and any immature individuals, or there may be one producing pair and a varying number of other group members, usually offspring from previous generations.
 There is not much known on its mating system, but according to different sources, and information on the possible social groups, it can be assumed that some may practice monogamous mating systems, and some may practice polyandrous mating systems.
 Both males and females invest energy in caring for the young, and all members of the group also help with juvenile care.
A Local Investing Opportunity Network, known as a (LION), is a loosely organized group of people who meet regularly with the goal of investing money in their local community.
 The group will generally consist of individuals who have money to invest and people who might be in a position where they would be seeking investors.
 The LION is designed to create opportunities for local businesses, individuals, and local investors to network and develop informal relationships.
 The U.S. Securities and Exchange Commission has created some very specific laws about how one can ask for money.
 These laws limit any kind of public offerings of shares/interest in a company (i.e. securities), unless there are proper filings and the people investing are considered accredited investors.
 There is a general exemption that the SEC does not regulate where the investors are friends with the people they are investing in.
 The LION hosts informal gatherings with the idea that friendships would form and the SEC guidelines would not be violated when any investments occur.
 The LION also documents who attends the gatherings as a means of creating a paper trail proving that the individuals involved in an investment had the opportunity to form an informal relationship.
Fritz Wächtler (7 January 1891 – 19 April 1945) was a Nazi German politician and Gauleiter of the eastern Bavarian administrative region of Gau Bayreuth.
 Trained as a primary school teacher, he also became head of the National Socialist Teachers League (NSLB) in 1935.
 During World War II he held the honorary rank of SS-Obergruppenführer and Reich Defense Commissar of Bayreuth.
 Prone to alcoholic outbursts and unpopular with the local residents, he eventually ran afoul of Martin Bormann in a political intrigue.
 Wächtler was shot on the orders from the Führerbunker near the end of the war in April, 1945.
The discontinuity effect is known as the markedly greater competitiveness displayed between different, interacting groups relative to the competitiveness displayed when individuals interact with other individuals.
 Given that group competition over scarce resources is believed to lead to group-level conflict (see realistic group conflict theory), it has been asserted that the link between competition and conflict is also considerably more powerful between groups than between individuals.
 While individuals within a group may prefer to be cooperative, once they join together to make a collective unit, individual orientations favoring cooperation tend to be overshadowed by competitive orientations of the group.
Propagule pressure (also termed introduction effort) is a composite measure of the number of individuals of a species released into a region to which they are not native.
 It incorporates estimates of the absolute number of individuals involved in any one release event (propagule size) and the number of discrete release events (propagule number).
 As the number of releases or the number of individuals released increases, propagule pressure also increases.
 Propagule pressure can be defined as the quality, quantity, and frequency of invading organisms (Groom, 2006).
 Propagule pressure is a key element to why some introduced species persist while others do not (Lockwood, 2005).
 Species introduced in large quantities and consistent quantities prove more likely to survive, whereas species introduced in small numbers with only a few release events are more likely to go extinct (Lockwood, 2005).
 Propagule pressure is a composite measure to the number of individuals released into a non-native region (Lockwood, 2005).
 Three approaches are used to study and measure propagule pressure.
 One approach introduces a specific amount of propagules into controlled plots.
 A second approach allows introduced species to mature and colonize naturally while observing native and non-native species during the colonization.
 The final approach used to study and measure propagule pressure utilizes past records of the numbers of individuals introduced, including natural introductions and intentional introductions (Colautti et al., 2003).
Hay'at Tahrir al-Sham (Arabic: هيئة تحرير الشام‎ ‎ , transliteration: "Hayʼat Taḥrīr al-Shām ", "Organization for the Liberation of the Levant" or "Levant Liberation Committee"), commonly referred to as Tahrir al-Sham and abbreviated HTS, is an active Salafist jihadist militant group involved in the Syrian Civil War.
 The group was formed on 28 January 2017 as a merger between Jabhat Fateh al-Sham (formerly al-Nusra Front), the Ansar al-Din Front, Jaysh al-Sunna, Liwa al-Haqq, and the Nour al-Din al-Zenki Movement.
 After the announcement, additional groups and individuals joined.
 The merger is currently led by Jabhat Fatah al-Sham and former Ahrar al-Sham leaders, although the High Command consists of leaders from other groups.
 Many groups and individuals defected from Ahrar al-Sham, representing their more conservative and Salafist elements.
 Currently, a number of analysts and media outlets still continue to refer to this group by its previous names, al-Nusra Front, or Jabhat Fateh al-Sham.
Sclerasterias is a genus of starfish in the family Asteriidae.
 Adult individuals have five arms but small, immature individuals have six.
 This led to the giving of a separate generic name to the juveniles, "Hydrasterias", before it was realised that only one genus was involved.
 These young individuals often undergo fissiparity.
 The disc splits into two parts, each bearing three arms, and new arms develop on each part to complete the complement of arms.
 This sometimes happens repeatedly and may be an adaptation to life in cold, deep seas where most of the species are found.
