T wave alternans (TWA) is a periodic beat-to-beat variation in the amplitude or shape of the T wave in an electrocardiogram (ECG or EKG)TWA was first described in 1908. At that time, only large variations ("macroscopic" TWA) could be detected. Those large TWAs were associated with increased susceptibility to lethal ventricular tachycardias. Most modern references to TWA refer to microvolt T wave alternans (MTWA), a non-invasive heart test that can identify patients who are at increased risk of sudden cardiac death. It is most often used in patients who have had myocardial infarctions (heart attacks) or other heart damage to see if they are at high risk of developing a potentially lethal cardiac arrhythmia. Those who are found to be at high risk would therefore benefit from the placement of a defibrillator device which can stop an arrhythmia and save the patient's life. The TWA test uses an electrocardiogram (ECG) measurement of the heart's electrical conduction using electrodes attached to one's torso. It takes approximately a half-hour to perform on an outpatient basis. The test looks for the presence of repolarization alternans (T-wave alternans), which is variation in the vector and amplitude of the T wave component of the EKG. The amount of variation is small, on the order of microvolts, so sensitive digital signal processing techniques are required to detect TWA. See also wikidoc article on TWA.

The Lombards () or Langobards (Latin: Langobardi) were a Germanic people who ruled most of the Italian Peninsula from 568 to 774. The medieval Lombard historian Paul the Deacon wrote in the History of the Lombards (written between 787 and 796) that the Lombards descended from a small tribe called the Winnili, who dwelt in southern Scandinavia (Scadanan) before migrating to seek new lands. Roman-era authors however reported them in the 1st century AD, as one of the Suebian peoples, in what is now northern Germany, near the Elbe river. By the end of the 5th century, the Lombards had moved into the area roughly coinciding with modern Austria and Slovakia north of the Danube river, where they subdued the Heruls and later fought frequent wars with the Gepids. The Lombard king Audoin defeated the Gepid leader Thurisind in 551 or 552; his successor Alboin eventually destroyed the Gepids in 567. Following this victory, Alboin decided to lead his people to Italy, which had become severely depopulated and devastated after the long Gothic War (535–554) between the Byzantine Empire and the Ostrogothic Kingdom there. In contrast with the Goths and the Vandals, the Lombards left Scandinavia and descended south through Germany, Austria and Slovenia, only leaving Germanic territory a few decades before reaching Italy. The Lombards would have consequently remained a predominantly Germanic tribe by the time they invaded Italy. The Lombards were joined by numerous Saxons, Heruls, Gepids, Bulgars, Thuringians, and Ostrogoths, and their invasion of Italy was almost unopposed. By late 569 they had conquered all of northern Italy and the principal cities north of the Po River except Pavia, which fell in 572. At the same time, they occupied areas in central Italy and southern Italy. They established a Lombard Kingdom in north and central Italy, later named Regnum Italicum ("Kingdom of Italy"), which reached its zenith under the 8th-century ruler Liutprand. In 774, the Kingdom was conquered by the Frankish king Charlemagne and integrated into the Frankish Empire. However, Lombard nobles continued to rule southern parts of the Italian peninsula well into the 11th century, when they were conquered by the Normans and added to their County of Sicily. In this period, the southern part of Italy still under Lombard domination was known to the foreigners by the name Langbarðaland (Land of the Lombards), in the Norse runestones. Their legacy is also apparent in the name of the region of Lombardy in Northern Italy.

Benjamin Solomon Carson Sr. (born September 18, 1951) is an American retired neurosurgeon, author, and politician who served as the 17th United States Secretary of Housing and Urban Development from 2017 to 2021. He was a candidate for President of the United States in the 2016 Republican primaries. He is considered a pioneer in the field of neurosurgery. Carson became the Director of Pediatric Neurosurgery at the Johns Hopkins Children’s Center in 1984 at age 33; he was the youngest chief of pediatric neurosurgery in the United States. At retirement, he was professor of neurosurgery, oncology, plastic surgery, and pediatrics at the Johns Hopkins School of Medicine. Carson's achievements include participating in the first reported separation of conjoined twins joined at the back of the head. Although surgically a success, the twins continued to suffer neurologic/medical complications. Additional accomplishments include performing the first successful neurosurgical procedure on a fetus inside the womb; developing new methods to treat brain-stem tumors; and revitalizing hemispherectomy techniques for controlling seizures. He wrote over 100 neurosurgical publications. He retired from medicine in 2013. Carson gained national fame among political conservatives after delivering a speech at the 2013 National Prayer Breakfast which was perceived as critical of the policies of President Barack Obama. Following widespread speculation of a presidential run, Carson officially announced his campaign for the 2016 Republican nomination for President in May 2015. Carson performed strongly in early polls, leading to him being considered a frontrunner for the nomination during the fall of 2015; however, his polling support began to decline following scrutiny of his foreign policy credentials after the November 2015 Paris attacks. Carson withdrew from the race after Super Tuesday, following a string of disappointing primary results, and endorsed Donald Trump. Following Trump's victory, Trump nominated Carson as Secretary of Housing and Urban Development, being confirmed by the United States Senate in a 58–41 vote on March 2, 2017. Carson has also been seen as a "symbol" of black conservatism. Carson has received numerous honors for his neurosurgery work, including more than 60 honorary doctorate degrees and numerous national merit citations. In 2001, he was named by CNN and TIME magazine as one of the nation's 20 foremost physicians and scientists, and was selected by the Library of Congress as one of 89 "Living Legends" on its 200th anniversary. In 2008, Carson was bestowed the Presidential Medal of Freedom, the highest civilian award in the United States. In 2010, he was elected into the National Academy of Medicine. He was the subject of the 2009 TV film Gifted Hands: The Ben Carson Story, where he was portrayed by Cuba Gooding Jr.

The Hippos
The Hippos were an American rock band formed in 1995 in Los Angeles, California, and disbanded in 2002. The band released three full-length albums. Their early work is best classified as part of the third wave of ska music, or as ska-punk, though in the later years of their career the band transitioned to a more synthesizer-driven power pop and rock sound.

Micraster is an extinct genus of echinoids from the Late Cretaceous to the early Eocene. Its remains have been found in Africa, Antarctica, Europe, and North America. Micraster was an infaunal echinoid living in a burrow below the sediment surface. The test is clearly bilateral and there is a deep anterior groove to take in water containing organic particles to the mouth. The tube feet keep a supply of nutrient-laden water moving into the burrow. The anus has a waste tube behind it.

Pokémon 3: The Movie – Spell of the Unown: Entei is a 2000 Japanese anime film directed by Kunihiko Yuyama as the third film in the Pokémon franchise. The film stars the voices of Rica Matsumoto, Ikue Ōtani, Mayumi Iizuka, Yūji Ueda, Koichi Yamadera, Megumi Hayashibara, Shin-ichiro Miki, Ai Kato, Masami Toyoshima, Akiko Yajima, and Naoto Takenaka. Like its predecessors, it is preceded by a short film, this one titled , which marks the debut of the mischievous Pichu Bros., who help Pikachu reunite with his trainer after being separated (without Ash even knowing, due to him preparing a party to celebrate the day Pikachu and he first met). This was also the first Pokémon film to premiere in an IMAX theater. The realistic crystallization and Unown created a 3D effect in the film. This was also the last Pokémon film to be released internationally by Warner Bros. until the release of Pokémon: Detective Pikachu in 2019. The Japanese opening theme is OK! 2000 by Rica Matsumoto, and the Japanese ending theme is The Day a Rainbow Was Born (Niji ga Umareta hi) by Kumiko Mori. The English opening theme is Pokemon Johto by PJ Lequerica, and the English ending theme is To Know the Unknown by Innosense.

10 Downing Street, also known colloquially in the United Kingdom as Number 10, is (along with the adjoining Cabinet Office at 70 Whitehall) the headquarters of the Government of the United Kingdom and the official residence and office of the First Lord of the Treasury, a post which, for much of the 18th and 19th centuries and invariably since 1905, has been held by the Prime Minister of the United Kingdom. The term "10 Downing Street", or just "Downing Street", is also used as a metonym for the Prime Minister's office. Situated in Downing Street in the City of Westminster, London, Number 10 is over 300 years old and contains approximately 100 rooms. A private residence for the officeholder's use occupies the third floor and there is a kitchen in the basement. The other floors contain offices and conference, reception, sitting and dining rooms where the Prime Minister works, and where government ministers, national leaders and foreign dignitaries are met and entertained. At the rear is an interior courtyard and a terrace overlooking a half-acre (0.2 ha) garden. Adjacent to St James's Park, Number 10 is near Buckingham Palace, the London residence of the British monarch, and the Palace of Westminster, the meeting place of both houses of parliament. No. 10 Downing Street is about 0.8 mile (1.3 km) from Buckingham Palace via the Birdcage Walk. Originally three houses, Number 10 was offered to Sir Robert Walpole by King George II in 1732. Walpole accepted on the condition that the gift was to the office of First Lord of the Treasury rather than to him personally. Walpole commissioned William Kent to join the three houses and it is this larger house that is known as Number 10 Downing Street. The arrangement was not an immediate success. Despite its size and convenient location near to Parliament, few early prime ministers lived there. Costly to maintain, neglected, and run-down, Number 10 was close to being demolished several times but the property survived and became linked with many statesmen and events in British history. In 1985 Margaret Thatcher said Number 10 had become "one of the most precious jewels in the national heritage".
