Southern European People
Southern European people are a pan-ethnic group, or multi-ethnic regional grouping, and the inhabitants of Southern Europe. South or Southern Europeans can usually trace back full or partial heritage to Greece, Italy, Spain , Portugal, as well as nations bordering with, or ethnoculturally related to, the region. As the pan-ethnic group is also culturally defined, rather than exclusively a geographical category, it often includes peoples inhabiting areas that are, at times, considered outside of the region. This can include people with heritage from Southern France, the Mediterranean islands of Corsica (also part of France ), Malta and Cyprus (geographically part of West Asia), Southeastern Europe's Albania and European Turkey. There are also descriptions of Southern Europeans which include ancestry from other nations in Southeast Europe, and countries of the South Slavs, particularly in diasporic identification. As Slavs, they are also often identified as Eastern Europeans. There is a large Southern European diaspora, with significant concentrations in the United Kingdom, North America (Southern European Americans and Canadians), and Southern European Australians in Oceania. Other subgroups of Europeans include Eastern European people and Northwestern European people.

Load Frequency Control System
Power systems are complex systems that have great importance to socio-economic development due to the fact that the entire world relies on the electric network power supply for day-to-day life. Therefore, for the stable operation of power systems, several protection and control techniques are necessary. Among various power system controls, the load frequency control (LFC) is the most time-consuming control mechanism of power systems due to the involvement of mechanical parts. As the control algorithms of frequency stabilization deliver control signals in the timescale of seconds, LFC systems cannot handle complicated data validation algorithms, making them more vulnerable to disturbances and cyber-attacks. Hence advanced research is highly encouraged in the field of development of attack resilient frequency stabilization techniques and in the area of cyber-security of LFC systems.

Nature Sports
Nature sports comprise a group of sporting activities that are developed and experienced in natural or rural areas, ranging from formal to informal practices. These practices are performed in a variety of natural contexts including on land (mountain biking, rock-climbing, trekking, etc.), in water (kayaking, sailing, surfing, windsurfing, etc.), and in the air (paragliding and hang-gliding, etc.). Nature sports have a spontaneous, playful nature, "with participation predominantly taking place in informal settings, often without governing bodies or clubs or other forms of external regulation". They are generally autonomous activities, even if some nature sports are practiced collectively, such as kayaking, or those which create sporting sub-cultures, such as in surfing.

Atomic Units
Atomic units (au or a.u.) form a system of natural units which is especially convenient for atomic physics calculations. There are two different kinds of atomic units, Hartree atomic units and Rydberg atomic units, which differ in the choice of the unit of mass and charge. This article deals with Hartree atomic units, where the numerical values of the following four fundamental physical constants are all unity by definition: In Hartree units, the speed of light is approximately [math]\displaystyle{ 137 }[/math]. Atomic units are often abbreviated "a.u." or "au", not to be confused with the same abbreviation used also for astronomical units, arbitrary units, and absorbance units in different contexts.

Sweet Corn
Sweet corn (Zea mays convar. saccharata var. rugosa; also called sweetcorn, sugar corn and pole corn) is a cereal with a high sugar content. Sweet corn is the result of a naturally occurring recessive mutation in the genes which control conversion of sugar to starch inside the ENO of the corn kernel. Unlike field corn varieties, which are harvested when the kernels are dry and mature (dent stage), sweet corn is picked when immature (milk stage) and prepared and eaten as a vegetable, rather than a grain. Since the process of maturation involves converting sugar to starch, sweet corn stores poorly and must be eaten fresh, canned, or frozen, before the kernels become tough and starchy. It is one of the six major types of corn, the others being dent corn, flint corn, pod corn, popcorn, and flour corn.

Vichy France
Vichy France (French: Régime de Vichy) is the common name of the French State (État français) headed by Marshal Philippe Pétain during World War II. Evacuated from Paris to Vichy in the unoccupied "Free Zone" (zone libre) in the southern part of metropolitan France which included French Algeria, it remained responsible for the civil administration of all France as well as the French colonial empire. From 1940 to 1942, while the Vichy regime was the nominal government of all of France except for Alsace-Lorraine, the Germans militarily occupied northern France. While Paris remained the de jure capital of France, the government chose to relocate to the town of Vichy, 360 km (220 mi) to the south in the zone libre, which thus became the de facto capital of the French State. Following the Allied landings in French North Africa in November 1942, southern France was also militarily occupied by Germany and Italy to protect the Mediterranean coastline. Petain's government remained in Vichy as the nominal government of France, albeit one that was obliged by circumstances to collaborate with Germany from November 1942 onwards. The government at Vichy remained there until late 1944, when it lost its authority due to the Allied invasion of France. After being appointed Premier by President Albert Lebrun, Marshal Pétain's cabinet agreed to end the war and signed an Armistice with Germany on 22 June 1940. On 10 July, the French Third Republic was dissolved, and Pétain established an authoritarian regime when the National Assembly granted him full powers. The Vichy government reversed many liberal policies and began tight supervision of the economy, calling for "National Regeneration", with central planning a key feature. Labour unions came under tight government control. Conservative Catholics became prominent and clerical input in schools resumed. Paris lost its avant-garde status in European art and culture. The media were tightly controlled and stressed virulent anti-Semitism, and, after June 1941, anti-Bolshevism. The French State maintained nominal sovereignty over the whole of French territory, but had effective full sovereignty only in the unoccupied southern zone libre ("free zone"). It had limited and only civil authority in the northern zones under military occupation. The occupation was to be a provisional state of affairs, pending the conclusion of the war, which at the time (1940) appeared imminent. The occupation also presented certain advantages, such as keeping the French Navy and French colonial empire under French control, and avoiding full occupation of the country by Germany, thus maintaining a degree of French independence and neutrality. The French government at Vichy never joined the Axis alliance. Germany kept two million French soldiers prisoner, carrying out forced labour. They were hostages to ensure that Vichy would reduce its military forces and pay a heavy tribute in gold, food, and supplies to Germany. French police were ordered to round up Jews and other "undesirables" such as communists and political refugees. Much of the French public initially supported the government, despite its undemocratic nature and its difficult position vis-à-vis the Germans, often seeing it as necessary to maintain a degree of French autonomy and territorial integrity. In November 1942, however, the zone libre was also occupied by Axis forces, leading to the disbandment of the remaining army and the sinking of France's remaining fleet and ending any semblance of independence, with Germany now closely supervising all French officials. Most of the overseas French colonies were originally under Vichy control, but with the Allied invasion of North Africa it lost one colony after another to Charles de Gaulle's Allied-oriented Free France. Public opinion in some quarters turned against the French government and the occupying German forces over time, when it became clear that Germany was losing the war, and resistance to them increased. Following the Allied invasion of France in June 1944 and the liberation of France later that year, the Free French Provisional government of the French Republic (GPRF) was installed by the Allies as France's government, led by de Gaulle. Under a "national unanimity" cabinet uniting the many factions of the French Resistance, the GPRF re-established a provisional French Republic, thus apparently restoring continuity with the Third Republic. Most of the legal French government's leaders at Vichy fled or were subject to show trials by the GPRF, and a number were quickly executed for "treason" in a series of purges (épuration légale). Thousands of collaborators were summarily executed by local communists and the Resistance in so-called "savage purges" (épuration sauvage). The last of the French state exiles were captured in the Sigmaringen enclave by de Gaulle's French 1st Armoured Division in April 1945. Pétain, who had voluntarily made his way back to France via Switzerland, was also put on trial for treason by the new Provisional government, and received a death sentence, but this was commuted to life imprisonment by de Gaulle. Only four senior Vichy officials were tried for crimes against humanity, although many more had participated in the deportation of Jews for extermination in Nazi concentration camps, abuses of prisoners, and severe acts against members of the Resistance.

Barack Obama "Hope" Poster
The Barack Obama "Hope" poster is an image of US president Barack Obama designed by American artist Shepard Fairey. The image was widely described as iconic and came to represent Obama's 2008 presidential campaign. It is a stylized stencil portrait of Obama in solid red, beige and (light and dark) blue, with the word "progress", "hope", or "change" below (and other words in some versions). Fairey based the design on a photo taken by former Associated Press (AP) freelance photographer Mannie Garcia. He created the design in a day and printed it first as a street poster. It was then widely distributed—both as a digital image and other paraphernalia—during the 2008 election season, with approval from the Obama campaign. By July 2008, Sticker Robot had printed over 200,000 vinyl "Hope" stickers, 75% of which had been given away to support the cause. The image became one of the most widely recognized symbols of Obama's campaign, spawning many variations and imitations, including some commissioned by the Obama campaign. In January 2009, after Obama had won the election, Fairey's mixed-media stenciled portrait version of the image was acquired by the Smithsonian Institution for its National Portrait Gallery. Later that month, the photograph that Fairey based the poster on was identified and the AP began negotiations for compensation. Fairey sued for a declaratory judgment that his poster was a fair use of the photograph. The parties settled out of court in January 2011. In February 2012, Fairey pleaded guilty to destroying and fabricating evidence showing that he had used the photograph; in September, he was sentenced to two years of probation, 300 hours of community service, and a fine of $25,000.

Digital Twin: Origin to Future
Digital Twin (DT) refers to the virtual copy or model of any physical entity (physical twin) both of which are interconnected via exchange of data in real time. Conceptually, a DT mimics the state of its physical twin in real time and vice versa. Application of DT includes real-time monitoring, designing/planning, optimization, maintenance, remote access, etc. Its implementation is expected to grow exponentially in the coming decades. The advent of Industry 4.0 has brought complex industrial systems that are more autonomous, smart, and highly interconnected. These systems generate considerable amounts of data useful for several applications such as improving performance, predictive maintenance, training, etc. A sudden influx in the number of publications related to ‘Digital Twin’ has led to confusion between different terminologies related to the digitalization of industries. Another problem that has arisen due to the growing popularity of DT is a lack of consensus on the description of DT as well as so many different types of DT, which adds to the confusion. This paper intends to consolidate the different types of DT and different definitions of DT throughout the literature for easy identification of DT from the rest of the complimentary terms such as ‘product avatar’, ‘digital thread’, ‘digital model’, and ‘digital shadow’. The paper looks at the concept of DT since its inception to its predicted future to realize the value it can bring to certain sectors. Understanding the characteristics and types of DT while weighing its pros and cons is essential for any researcher, business, or sector before investing in the technology.

Green Building Rating Systems (GBRSs)
Green Building Rating Systems (GBRSs) are typically third-party, voluntary, and market driven standards that measure buildings’ sustainability level by multi-criteria assessment, and encourage the adoption of environmentally, socially and economically sustainable practices in design, construction and operation of buildings (or neighborhoods). GBRSs aim at guiding and assessing the project throughout all its life cycle, thus limiting the negative impact on the environment, as well as on the building occupants’ health and well-being, and even reducing operational costs. Hundreds of GBRSs are now available worldwide, varying in approaches, application processes, and evaluation metrics. BREEAM, CASBEE, Green Star and LEED are among the most applied worldwide. Despite some differences, they all adhere to the same general evaluation structure: project performances ares measured using a set of relevant indicators, grouped per topics such as water management, energy use, materials, site qualities. Each assessed requirement is assigned a score/judgment, the total of which determines the level of sustainability achieved. In addition to regular updates, a current trend is to improve the effectiveness of protocols, making them more comprehensive and accurate, while keeping them easy to use.

Social Presence Theory
Social presence theory explores how the "sense of being with another" is influenced by digital interfaces in human-computer interactions. Developed from the foundations of interpersonal communication and symbolic interactionism, social presence theory was first formally introduced by John Short, Ederyn Williams, and Bruce Christie in The Social Psychology of Telecommunications. Research on social presence theory has recently developed to examine the efficacy of telecommunications media, including SNS communications. The theory notes that computer-based communication is lower in social presence than face-to-face communication, but different computer-based communications can affect the levels of social presence between communicators and receivers.

Huītzilōpōchtli
In Aztec mythology, Huitzilopochtli (Template:Lang-nci-IPA, modern Nahuatl pronunciation (help·info)) is the deity of war, sun, human sacrifice, and the patron of the city of Tenochtitlan. He was also the tribal god of the Mexicas, also known as the Aztecs, of Tenochtitlan. Many in the pantheon of deities of the Aztecs were inclined to have a fondness for a particular aspect of warfare. However, Huitzilopochtli was known as the primary god of war in ancient Mexico. Since he was the patron god of the Mexica, he was credited with both the victories and defeats that the Mexica people had on the battlefield. The people had to make sacrifices to him to protect the Aztec from infinite night. He wielded Xiuhcoatl, the fire serpent, as a weapon, thus also associating Huitzilopochtli with fire. As noted by the Spaniards during their discovery and conquest of the Aztec Empire (wherein they recorded the deity's name as Huichilobos), human sacrifice was common in worship ceremonies, which took place frequently and in numerous temples throughout the region, and when performed they typically sacrificed multiple victims per day at a given temple.

Natural Emulsion Stabilizers
Natural emulsion stabilizers are polymers of amino acid, nucleic acid, carbohydrate, etc., which are derived from microorganisms, bacteria, and other organic materials. Plant and animal proteins are basic sources of natural emulsion stabilizers. Pea protein-maltodextrin and lentil protein feature entrapment capacity up to 88%, (1–10% concentrated), zein proteins feature 74–89% entrapment efficiency, soy proteins in various concentrations increase dissolution, retention, and stability to the emulsion and whey proteins, egg proteins, and proteins from all other animals are applicable in membrane formation and encapsulation to stabilize emulsion/nanoemulsion. In pharmaceutical industries, phospholipids, phosphatidyl choline (PC), phosphatidyl ethanol-amine (PE), and phosphatidyl glycerol (PG)-based stabilizers are very effective as emulsion stabilizers. Lecithin (a combination of phospholipids) is used in the cosmetics and food industries. Various factors such as temperature, pH, droplets size, etc. destabilize the emulsion. Therefore, the emulsion stabilizers are used to stabilize, preserve and safely deliver the formulated drugs, also as a preservative in food and stabilizer in cosmetic products. Natural emulsion stabilizers offer great advantages because they are naturally degradable, ecologically effective, non-toxic, easily available in nature, non-carcinogenic, and not harmful to health.

Voltaire
François-Marie Arouet (French: [fʁɑ̃swa maʁi aʁwɛ]; 21 November 1694 – 30 May 1778), known by his nom de plume Voltaire (/vɒlˈtɛər, voʊl-/; also US: /vɔːl-/, French: [vɔltɛːʁ]), was a French Enlightenment writer, historian, and philosopher famous for his wit, his criticism of Christianity—especially the Roman Catholic Church—as well as his advocacy of freedom of speech, freedom of religion, and separation of church and state. Voltaire was a versatile and prolific writer, producing works in almost every literary form, including plays, poems, novels, essays, histories, and scientific expositions. He wrote more than 20,000 letters and 2,000 books and pamphlets. He was an outspoken advocate of civil liberties, and was at constant risk from the strict censorship laws of the Catholic French monarchy. His polemics witheringly satirized intolerance, religious dogma, and the French institutions of his day.

Pingu
Pingu is a Swiss-British stop-motion clay animated children's comedy television series created by Otmar Gutmann and produced from 1990 to 2000 for Swiss television, and from 2003 to 2006 for British television by The Pygos Group (formerly Trickfilmstudio and Pingu Filmstudio). It centres on a family of anthropomorphic penguins who live at the South Pole; the main character is the family's son and title character, Pingu. The series originally ran for four series (each series made up of multiple seasons) from 7 March 1990 to 9 April 2000 on SF DRS and was then renewed for two more series from 1 August 2003 to 3 March 2006 on BBC Two. Pingu won a BAFTA award. Pingu was a worldwide hit, due to its lack of real spoken language: nearly all dialogue is in an invented grammelot "penguin language" referred to as 'Penguinese', consisting of babbling, muttering, and his characteristic sporadic loud honking noise, which can be popularly recognized as "Noot noot!" or other variants, stated to be "Noo, Noo!" by the defunct Pingu website's trivia page, accompanied by turning his beak into a megaphone-like shape. Within the first 4 series, all the characters were performed by Italian voice actor Carlo Bonomi, using a language of noises that he had already developed and used for the earlier Osvaldo Cavandoli's La Linea. In series 5 and 6, the Pingu cast was jointly voiced by David Sant and Marcello Magni. A Japanese reboot of the series, titled Pingu in the City, began airing on NHK-E on 7 October 2017.
