Almost Mathieu operator
In mathematical physics, the almost Mathieu operator, named for its similarity to the Mathieu operator introduced by Émile Léonard Mathieu, arises in the study of the quantum Hall effect. It is given by

acting as a self-adjoint operator on the Hilbert space . Here  are parameters. In pure mathematics, its importance comes from the fact of being one of the best-understood examples of an ergodic Schrödinger operator.  For example, three problems (now all solved) of Barry Simon's fifteen problems about Schrödinger operators "for the twenty-first century" featured the almost Mathieu operator. In physics, the almost Mathieu operators can be used to study metal to insulator transitions like in the Aubry–André model.

For , the almost Mathieu operator is sometimes called Harper's equation.

Mathematical physics
Mathematical physics is the development of mathematical methods for application to problems in physics. The Journal of Mathematical Physics defines the field as "the application of mathematics to problems in physics and the development of mathematical methods suitable for such applications and for the formulation of physical theories". An alternative definition would also include those mathematics that are inspired by physics, known as physical mathematics.
Terrafirma Dyip draft history
The Terrafirma Dyip first participated in the Philippine Basketball Association (PBA) draft on August 24, 2014, two months before their first PBA season. The Dyip (then-known as Kia Sorento) entered the league through expansion together with the Blackwater Elite.

Manny Pacquiao became the team's first draft choice, the 11th pick in the 2014 PBA draft. Since then, they have selected four number one draft picks: CJ Perez, Roosevelt Adams, Joshua Munzon, and most recently, Stephen Holt.

CJ Perez
Christian Jaymar Perez (born November 17, 1993) is a Filipino professional basketball player for the San Miguel Beermen of the Philippine Basketball Association (PBA). He was selected 1st overall in the 2018 PBA draft by Columbian Dyip.

In 2025, he made his coaching debut as an assistant coach for the PSP Gymers of the Women's Maharlika Pilipinas Basketball League (WMPBL).
Memkumlis
Memkumlis or, officially Meem Quam Leese, Memkoomlish, Memqumlis, ʼmimkumlis or Miʼmkwamlis, commonly known as Mamalilaculla,  which is actually the name of the subgroup of the Kwakwakaʼwakw whose home it is, is located on the west side of Village Island in the Johnstone Strait region of the Central Coast of British Columbia.

The village is on Mahmalillikullah Indian Reserve No. 1 on Eliot Passage, which was created in 1886.  The name means "village with rocks and islands out front", or as translated by famous chief and carver Mungo Martin, "group of little islands" and by Franz Boas as "round things [islands] in front at beach".

Johnstone Strait
The Johnstone Strait (French: Détroit de Johnstone) is a 110 km (68 mi) channel along the north east coast of Vancouver Island in British Columbia, Canada.  Opposite the Vancouver Island coast, running north to south, are Hanson Island, West Cracroft Island, the mainland British Columbia Coast, Hardwicke Island, West Thurlow Island and East Thurlow Island.  At that point, the strait meets the Discovery Passage which connects to the Georgia Strait.
WPPI
WPPI (95.5 FM) is a sports radio station in the Portland, Maine, area.  The station is owned by Atlantic Coast Radio.

WPPI serves as a simulcast of WPEI (95.9 FM) in Saco. Both stations, in turn, mostly carry the same programs as WEEI-FM from Boston. Some local commercials take the place of Boston commercials, and some WEEI-FM game broadcasts are substituted with Fox Sports Radio. WPPI also carries University of Maine Black Bear football and ice hockey, and Portland Pirates ice hockey.

Portland Pirates
The Portland Pirates were a minor league professional ice hockey team in the American Hockey League (AHL). Their home arena was the Cross Insurance Arena in downtown Portland, Maine. The franchise was previously known as the Baltimore Skipjacks from 1982 to 1993.

The Pirates were affiliated with the Washington Capitals (1993–2005), Anaheim Ducks (2005–2008), Buffalo Sabres (2008–2011), Phoenix/Arizona Coyotes (2011–2015), and the Florida Panthers (2015–2016). The organization hosted the AHL All-Star Classic in 2003 and 2010.

On May 4, 2016, the Pirates announced it had signed a letter of intent with an outside buyer to sell and relocate the franchise for the 2016–17 season. It was reported that the team would be relocated to Springfield, Massachusetts following the pending sale and relocation of the Springfield Falcons franchise to Tucson, Arizona. The transaction was approved by the AHL on May 23, 2016, and the franchise became the Springfield Thunderbirds.
Jach'a Waylla Punta
Jach'a Waylla Punta (Aymara jach'a big, waylla Stipa obtusa, a kind of feather grass, Spanish punta point, also spelled Jacha Huaylla Punta or Jacha Huayna Punta) is a 4,743-metre-high (15,561 ft) mountain in the Andes of Bolivia. It is located in the La Paz Department, Larecaja Province, Sorata Municipality. Jach'a Waylla Punta lies in the northern extensions of the Cordillera Real southeast of the mountain Wila Wilani and south of Wankar Quta Qullu. It is situated at the rivers Q'asiri Jawira and Ch'uch'u Jawira.

Cordillera Real (Bolivia)
The Cordillera Real is a mountain range in the South American Altiplano of Bolivia, forming part of the Andes. This range of fold mountains, largely composed of granite, is located southeast of Lake Titicaca, and east of the Bolivian capital of La Paz. The range stretches 125 km in length and 20 km in width. Even though it is only 17° south of the Equator, the Cordillera Real is relatively densely glaciated. This is due to its proximity to the Amazon lowlands with its associated moist air masses.
Guldborg
Guldborg is a fishing village spanning the islands of Falster and Lolland in Guldborgsund Municipality, Region Zealand, in Denmark. The village is located at the narrowest point between the two islands where Guldborg Bridge crosses Guldborgsund (or Guldborg) Sound. In 2025 the village had a population of 495, with about 400 living on Lolland.

Falster
Falster (Danish: [ˈfælˀstɐ]) is an island in south-eastern Denmark with an area of 486.2 km2 (187.7 sq mi) and 43,398 inhabitants as of 1 January 2010. Located in the Kattegat, Belts and Sound area, it is part of Region Zealand and is administered by Guldborgsund Municipality. Falster includes Denmark's southernmost point, Gedser Odde, near Gedser.

The largest town is Nykøbing Falster with over 40% of the island's inhabitants. Other towns include Stubbekøbing, Nørre Alslev and Gedser.

Falster has motor and railway links both to the larger island of Zealand to the north and to the island of Lolland to the south-west. These links also lead to the smaller islands of Masnedø and Farø. European route E47 links Copenhagen to Hamburg (Germany) via Falster.
Owner-operator
An owner-operator is an owner of a small business or microbusiness who also runs the day-to-day operations of the company. Owner-operators are found in many business models and franchising companies in many different industries like restaurant chains, health care, logistics, maintenance, repair, and operations.

Business model
A business model describes how a business organization creates, delivers, and captures value, in economic, social, cultural or other contexts. The model describes the specific way in which the business conducts itself, spends, and earns money in a way that generates profit. The process of business model construction and modification is also called business model innovation and forms a part of business strategy.

In theory and practice, the term business model is used for a broad range of informal and formal descriptions to represent core aspects of an organization or business, including purpose, business process, target customers, offerings, strategies, infrastructure, organizational structures, profit structures, sourcing, trading practices, and operational processes and policies including culture.
2008 Dubai Sevens
The Dubai Sevens is played annually as part of the IRB Sevens World Series for international rugby sevens (seven-a-side version of rugby union). The 2008 competition was held on November 28 and 29 at The Sevens, a brand-new facility built to host the 2009 Rugby World Cup Sevens. It was the first of eight events in the 2008-09 IRB Sevens World Series. The top-tier Cup trophy was won by South Africa.

This was the first edition of the Dubai Sevens to be held at The Sevens. Previous editions were held at the Dubai Exiles Rugby Ground.

2008–09 IRB Sevens World Series
The 2008–09 IRB Sevens World Series was the tenth of an annual IRB Sevens World Series of rugby union sevens tournaments for full national sides run by the International Rugby Board since 1999–2000.

South Africa clinched the 2008–09 World Series, its first Series title.  The defending series champions New Zealand finished fourth.

Sevens is traditionally played in a two-day tournament format. However, the most famous event, the Hong Kong Sevens, is played over three days, largely because it involves 24 teams instead of the normal 16. Starting in 2008–09, the Australia leg (which involves the normal 16 teams) was spread out over a three-day period.
Hans-Wilhelm Müller-Wohlfahrt
Dr. Hans-Wilhelm Müller-Wohlfahrt, (born 12 August 1942) in Leerhafe, Wittmund, East Frisia is a German orthopedist and sports physician.

He gained recognition for his roles as Germany's national football team doctor for 23 years (1995–2018) and club doctor of Bayern Munich (1977–2015, 2017–2020).

Robert Schleip
Robert Schleip (born 1954) is a German psychologist, human biologist and author, best known for his work in the field of fascia. He serves as the director of the Fascia Research Group, a research collaboration between the University of Ulm and the Technical University of Munich. Schleip is also the founding director of the Fascia Research Society, the research director of the European Rolfing Association and vice president of the Ida P. Rolf Research Foundation. He is involved in the alternative medicine field of rolfing.
Brellochs reaction
In organoboron chemistry, the Brellochs reaction provides a way to generate the monocarboranes. The Brellochs method uses formaldehyde to insert single carbon atoms into boron hydrides.

Illustrative is the synthesis of CB9H14− from commercially available decaborane.

B10H14 +  CH2O  + 2 OH−  +  H2O  →  CB9H14−  +  B(OH)4−  +  H2

Oxidation of the arachno anion gives nido-6-CB9H12−.  Base degradation of the latter gives arachno-4-CB8H14.

Organoboron chemistry
Organoboron chemistry or organoborane chemistry studies organoboron compounds, also called organoboranes.  These chemical compounds combine boron and carbon; typically, they are organic derivatives of borane (BH3), as in the trialkyl boranes.

Organoboranes and -borates enable many chemical transformations in organic chemistry — most importantly, hydroboration and carboboration.  Most reactions transfer a nucleophilic boron substituent to an electrophilic center either inter- or intramolecularly.  In particular, α,β-unsaturated borates and borates with an α leaving group are highly susceptible to intramolecular 1,2-migration of a group from boron to the electrophilic α position. Oxidation or protonolysis of the resulting organoboranes generates many organic products, including alcohols, carbonyl compounds, alkenes, and halides.
Baltimore Lifeboat Station
Baltimore Lifeboat Station is located at Bull Point, near Baltimore, a town approximately 85 km (53 mi) south west of Cork, on the south-west tip of County Cork, on the south coast of Ireland.

A lifeboat station was established at Baltimore by the Royal National Lifeboat Institution (RNLI) in 1919.

The station currently operates a Tamar-class All-weather lifeboat, 16-22 Alan Massey (ON 1302), on station since 2012, and a B-class (Atlantic 85) Inshore lifeboat, Rita Daphne Smyth (B-910), on station since 2018.

Awards of the Royal National Lifeboat Institution
The National Institution for the Preservation of Life from Shipwreck was established on 4 March 1824, becoming the Royal National Institution for the Preservation of Life from Shipwreck (RNIPLS) on 20 March 1824, when it received royal approval from King George IV. The Institution became the Royal National Lifeboat Institution (RNLI) on 5 October 1854.

Ever since its inception in 1824, a number of awards have been established by the Institution, both for gallantry at sea, and for service to the Institution. None are approved by the Crown, and are therefore unofficial awards. As such, they do not appear in the official British order of wear, although the principal lifesaving award, a Medal of the RNLI, can be worn on the right breast in uniform by members of the British armed forces.
Glockner Group
The Glockner Group (German: Glocknergruppe) is a sub-group of the Austrian Central Alps in the Eastern Alps, and is located in the centre section of the High Tauern on the main chain of the Alps.

The Glockner Group lies in Austria in the federal states of Salzburg, Tyrol and Carinthia. The three states meet at a tripoint on the summit of the Eiskögele (3,436 m (AA)).

The highest summit of the Glockner Group and also the highest peak in Austria is the Großglockner (3,798 m above sea level (AA)), which gives the mountain group its name. Considerable portions of the Glockner Group belong to the core zone of the High Tauern National Park. Also found in the Glockner Group is the Pasterze, the largest glacier in Austria.

Main chain of the Alps
The main chain of the Alps, also called the Alpine divide is the central line of mountains that forms the drainage divide of the range.  Main chains of mountain ranges are traditionally designated in this way, and generally include the highest peaks of a range. The Alps are something of an unusual case in that several significant groups of mountains are separated from the main chain by sizable distances.  Among these groups are the Dauphiné Alps, the Eastern and Western Graians, the entire Bernese Alps, the Tödi, Albula and Silvretta groups, the Ortler and Adamello ranges, and the Dolomites of Veneto and South Tyrol, as well as the lower Alps of Vorarlberg, Bavaria, and Salzburg.
Torquay Surf Beach
Torquay Surf Beach, also known as the Torquay Back Beach (to distinguish it from the nearby Torquay Front Beach), is a highly popular patrolled coastal beach facing the Bass Strait in Torquay, Victoria, Australia. It lies southwest of Torquay's town centre and adjacent to the start of the Great Ocean Road, attracting surfers, beachgoers and tourists. The beach reserve is managed by the Surf Coast Shire council in partnership with the Great Ocean Road Coast and Parks Authority, and seasonal patrolling is provided by the Torquay Surf Life Saving Club (part of Life Saving Victoria).

Torquay, Victoria
Torquay (/tɔːˈkiː/ tor-KEY) is a town in Surf Coast Shire, Victoria, Australia, which faces Bass Strait, 21 km south of Geelong and is the gateway to the Great Ocean Road. It is bordered on the west by Spring Creek and its coastal features include Point Danger and Zeally Bay.  At the 2021 census, Torquay had a population of 18,534.
Janq'u K'ark'a (Larecaja-Omasuyos)
Janq'u K'ark'a (Aymara janq'u white, k'ark'a crevice, fissure, crack, "white crevice", also  spelled Jankho Kharka) is a mountain in the Cordillera Real in the Andes of Bolivia, about 5,200 metres (17,060 ft) high. It is situated in the La Paz Department, Larecaja Province, Sorata Municipality, and in the Omasuyos Province, Achacachi Municipality. Janq'u K'ark'a lies south of the Janq'u Uma-Illampu massif, southeast of the mountain Quña Quñani and the lakes Warawarani (Huara Huarani) and Jisk'a Warawarani (Jiskha Huara Huarani).

Cordillera Real (Bolivia)
The Cordillera Real is a mountain range in the South American Altiplano of Bolivia, forming part of the Andes. This range of fold mountains, largely composed of granite, is located southeast of Lake Titicaca, and east of the Bolivian capital of La Paz. The range stretches 125 km in length and 20 km in width. Even though it is only 17° south of the Equator, the Cordillera Real is relatively densely glaciated. This is due to its proximity to the Amazon lowlands with its associated moist air masses.
British Academy Medal
The British Academy Medal is awarded annually by the British Academy to up to three individuals or groups. It is awarded for "outstanding achievement that has transformed understanding of a particular subject or field of study in ... any branch of the humanities and social sciences". It was first awarded in 2013. It is the first medal awarded by the British Academy for any subject within the remit of the academy. According to a reputation survey conducted in 2018, it is the third most prestigious interdisciplinary award in the social sciences, after the Holberg Prize and the Stein Rokkan Prize for Comparative Social Science Research. The British Academy medal is no longer being awarded since 2019.

Stein Rokkan Prize for Comparative Social Science Research
The Stein Rokkan Prize for Comparative Social Science Research is an academic honour awarded by the International Science Council, the University of Bergen and the European Consortium for Political Research, in memory of the political scientist and sociologist Stein Rokkan. It is awarded to scholars who have made "a very substantial and original contribution in comparative social science research" in the form of a published monograph. The monograph must have been published within the two calendrical years preceding the award. The prize is awarded annually and is worth €5000.

According to a reputation survey conducted in 2013 and 2014, the Stein Rokkan Prize is the second most prestigious international academic award in political science, after the Johan Skytte Prize in Political Science. A reputation survey conducted in 2018 found the Stein Rokkan Prize to be the most prestigious interdisciplinary award in the social sciences (jointly with the Holberg Prize).
Sosippus
The spider genus Sosippus is, with other genera in the subfamily Hippasinae, unique among the spiders in the family Lycosidae in producing a large funnel-web resembling that of the Agelenidae. The posterior spinnerets are more elongate than in other wolf spiders.

Their eyes are arranged in three rows, with four small eyes in the anterior (lowest), two large eyes in the second, and two smaller lateral eyes in the third row.

Sosippus is found from Central America to the southern United States.

The closest relatives are found in the genus Aglaoctenus.

The species of Sosippus seem to have diverged relatively recently in geologic time.

Wolf spider
Wolf spiders are members of the family Lycosidae (from Ancient Greek  λύκος (lúkos) 'wolf'), named for their robust and agile hunting skills and excellent eyesight.

They live mostly in solitude, hunt alone, and usually do not spin webs. Some are opportunistic hunters, pouncing upon prey as they find it or chasing it over short distances; others wait for passing prey in or near the mouth of a burrow.

Wolf spiders resemble nursery web spiders (family Pisauridae), but wolf spiders carry their egg sacs by attaching them to their spinnerets, while the Pisauridae carry their egg sacs with their chelicerae and pedipalps.

Two of the wolf spider's eight eyes are large and prominent; this distinguishes them from nursery web spiders, whose eyes are all of roughly equal size. This can also help distinguish them from the similar-looking grass spiders.
West Angelas mine
The West Angelas mine is an iron ore mine located in the Pilbara region of Western Australia, 110 kilometres North West of Newman.

The mine is owned by Robe River Iron Associates (53% Rio Tinto) and operated by Rio Tinto Iron Ore and is one of twelve iron ore mines the company operates in the Pilbara. In 2009, the combined Pilbara operations produced 202 million tonnes of iron ore, a 15 percent increase from 2008. The Pilbara operations accounted for almost 13 percent of the world's 2009 iron ore production of 1.59 billion tonnes.

The Hamersley Range, where the mine is located, contains 80 percent of all identified iron ore reserves in Australia and is one of the world's major iron ore provinces.

Pilbara Iron
Pilbara Iron manages assets for Hamersley Iron Pty Ltd, a subsidiary of Rio Tinto, and Robe River Iron Associates, an unincorporated joint venture between Rio Tinto (53%) and Japanese steel companies Mitsui Iron Ore Development (33%) and Nippon Steel (14%).
All of these companies are involved in the mining of iron ore, predominantly from the Pilbara region of Western Australia.

All of these companies are involved in the mining of iron ore, predominantly from the Pilbara region of Western Australia.

In 2004, it was announced that Hamersley and Robe River would merge their operations as Pilbara Iron. The concept had been tested by the formation of Pilbara Rail in 2001, which generated more than $16 million in savings. Pilbara Rail was folded into Pilbara Iron in 2005. Each company continues to market products separately and retains ownership and profits from the underlying mines, as well as strategic development of their own mineral resources.
Knights Templar Church, Dover
The Knights Templar Church in Dover is the ruins of a medieval church on Bredenstone hill, part of the Dover Western Heights in Kent, England. It has been designated by English Heritage as a scheduled monument.

Dover Western Heights
The Western Heights of Dover is a series of forts and ditches in Dover, England. They were created in the 18th and 19th centuries to augment the existing defences and protect the key port of Dover from both seaward and landward attack. In the early 20th century, the Dover Western Heights was collectively reputed to be the "strongest and most elaborate" fortification in the country. The Army withdrew from the Heights in 1956–61. They are now a local nature reserve.
Ensitrelvir
Ensitrelvir, sold under the brand name Xocova is an antiviral medication used as a treatment for COVID-19. It was developed by Shionogi in partnership with Hokkaido University and acts as an orally active 3C-like protease inhibitor. It is taken by mouth.

The most common adverse events include transient decreases in high-density lipoprotein and increased blood triglycerides.

Antiviral drug
Antiviral drugs are a class of medication used for treating viral infections. Most antivirals target specific viruses, while a broad-spectrum antiviral is effective against a wide range of viruses. Antiviral drugs are a class of antimicrobials, a larger group which also includes antibiotic (also termed antibacterial), antifungal and antiparasitic drugs, or antiviral drugs based on monoclonal antibodies. Most antivirals are considered relatively harmless to the host, and therefore can be used to treat infections. They should be distinguished from virucides, which are not medication but deactivate or destroy virus particles, either inside or outside the body. Natural virucides are produced by some plants such as eucalyptus and Australian tea trees.
