Kizuna AI (Japanese: キズナアイ), or AI Kizuna in non-Japanese order, is a Japan ese virtual YouTuber and self-proclaimed artificial intelligence. As of 2019, she operates three YouTube channels, "A.I.Channel", "A.I.Games", and "A.I.Channel China." Kizuna claims to be the world's first Virtual YouTuber, though the first channel to use a CG avatar for vlogging purposes on YouTube was the channel of English-Japanese Ami Yamato, who debuted her first video on 2011. and later the adoption of a similar concept by Mattel, which involved the use of a virtual personality for a 2015 advertisement campaign. On 29 November 2016, Kizuna started posting videos on her first YouTube channel, "A.I.Channel". A second channel, "A.I. Games," was opened in March 2017 for gaming-related content. A third channel, "A.I.Channel China", launched in June 2019 for a Chinese audience. Many speculate that Kizuna was created using the MikuMikuDance software, and given facial expression and actions using motion capture technology. Kizuna's video content is similar to many other YouTubers, consisting primarily of discussions, Q&A videos, and more traditional "Let's Play" videos. Because Kizuna only communicates in Japanese, fans contribute translations for her videos, and there exists entire unofficial communities built around these translators, filling the void of an official English community. Kizuna has also performed at the various Anime Conventions, and has also worked with many game companies.

Existing Reinforcement Concepts for 3D Printed Concrete

3D printed concrete (3DPC) technology is relatively new, and it still has many challenges to overcome if it is going to replace, at least in part, conventional concrete construction. One of the difficulties is the lack of proper reinforcement for printing building scale structures. Different ideas proposed to reinforce 3D printed concrete can be categorized based on the material (e.g., steel, thermoplastic, FRP, and other materials) or stage to place reinforcement (pre-installed, in-process, and post-installed reinforcement). However, limited available test data and even fewer examples of the use of the proposed reinforcement concepts in actual construction have retarded the development of this advanced technology. Before developing some novel concepts, looking back to review what has been achieved in this regard is a necessary step to move forward. This section will discuss the recent attempts to reinforce 3D printed concrete based on different stages to place the reinforcement.

Enlightenment in Buddhism

The English term enlightenment is the western translation of the abstract noun bodhi, (/ˈboʊdi/; Sanskrit: बोधि; Pali: bodhi), the knowledge or wisdom, or awakened intellect, of a Buddha. The verbal root budh- means "to awaken," and its literal meaning is closer to "awakening." Although the term buddhi is also used in other Indian philosophies and traditions, its most common usage is in the context of Buddhism. The term "enlightenment" was popularised in the Western world through the 19th century translations of Max Müller. It has the western connotation of general insight into transcendental truth or reality. The term is also being used to translate several other Buddhist terms and concepts, which are used to denote (initial) insight (prajna (Sanskrit), wu (Chinese), kensho and satori(Japanese)); knowledge (vidhya); the "blowing out" (Nirvana) of disturbing emotions and desires and the subsequent freedom or release (vimukti); and the attainment of supreme Buddhahood (samyak sam bodhi), as exemplified by Gautama Buddha. What exactly constituted the Buddha's awakening is unknown. It may probably have involved the knowledge that liberation was attained by the combination of mindfulness and dhyāna, applied to the understanding of the arising and ceasing of craving. The relation between dhyana and insight is a core problem in the study of Buddhism, and is one of the fundamentals of Buddhist practice. In the western world the concept of (spiritual) enlightenment has taken on a romantic meaning. It has become synonymous with self-realization and the true self and false self, being regarded as a substantial essence being covered over by social conditioning., , ,

Void Coefficient

In nuclear engineering, the void coefficient (more properly called void coefficient of reactivity) is a number that can be used to estimate how much the reactivity of a nuclear reactor changes as voids (typically steam bubbles) form in the reactor moderator or coolant. Net reactivity in a reactor is the sum total of all these contributions, of which the void coefficient is but one. Reactors in which either the moderator or the coolant is a liquid typically will have a void coefficient value that is either negative (if the reactor is under-moderated) or positive (if the reactor is over-moderated). Reactors in which neither the moderator nor the coolant is a liquid (e.g., a graphite-moderated, gas-cooled reactor) will have a void coefficient value equal to zero. It is unclear how the definition of 'void' coefficient applies to reactors in which the moderator/coolant is neither liquid nor gas (supercritical water reactor).

War brides are women who married military personnel from other countries in times of war or during military occupations, a practice that occurred in great frequency during World War I and World War II. Among the largest and best documented examples of this were the marriages between American servicemen and German women which took place after World War II. By 1949, over 20,000 German war brides had emigrated to the United States. Furthermore, it is estimated that there are "... 15,000 Australian women who married American servicemen based in Australia during World War II and moved to the US to be with their husbands". Allied servicemen also married many women in other countries where they were stationed at the end of the war, including France , Italy, Luxembourg, the Philippines , Japan and China . This also occurred in Korea and Vietnam with the later wars in those countries involving U.S. troops and other anti-communist soldiers. As many as 70,000 GI war brides left the United Kingdom, 150,000 to 200,000 hailed from continental Europe, 15,500 from Australia and 1,500 from New Zealand, between the years 1942 and 1952. The reasons for women marrying foreign soldiers and leaving their homelands vary. Particularly after World War II, many women in devastated European and Asian countries saw marriage as a means of escaping their devastated countries.

Chitin, being the second most abundant biopolymer after next to cellulose, has been gaining popularity since its initial first discovery by Braconot in 1811. However, fundamental knowledge and literature on about chitin and its derivatives from insects are difficult to obtain. The most common and sought-after sources of chitin are shellfishes (especially crustaceans) and other aquatic invertebrates. The amount of shellfishes available is obviously restricted by the amount of food waste that is allowed; hence, it is a limited resource. Therefore,Hence, insects are the best choices since, out of 1.3 million species in the world, 900,000 are insects, making them the most abundant species in the world. In this review, a total of 82 samples from shellfishes—crustaceans and mollusks (n = 46), insects (n = 23), and others (n = 13)—have been collected and studied for their chemical extraction of chitin and its derivatives. The aim of this paper is to review the extraction method of chitin and chitosan for a comparison of the optimal demineralization and deproteinization processes with, so as to consideration of insects as alternative sources of chitin. The methods employed in this review are based on comprehensive bibliographic research. Based on previous data, chitin and chitosan yield contents of insects in their study favorably compares and competes with those of commercial chitin and chitosan—for example, 45% in Bombyx eri, 36.6% in Periostracum cicadae (cicada sloughs), and 26.2% in Chyrysomya megacephala. Therefore, according to the data reported by previous researchers, with comparable yield values to those of against crustacean chitin and the great interests of in insects as alternative sources, efforts towards comprehensive knowledge in this field are relevant.

Civilians under international humanitarian law are "persons who are not members of the armed forces" and are not "combatants if they [do not] carry arms openly and respect the laws and customs of war". It is slightly different from a non-combatant, as some non-combatants are not civilians (for example, military chaplains attached to the belligerent party or military personnel serving with a neutral country). Civilians in the territories of a party to an armed conflict are entitled to certain privileges under the customary laws of war and international treaties such as the Fourth Geneva Convention. The privileges that they enjoy under international law depends on whether the conflict is an internal one (a civil war) or an international one. In some nations, uniformed members of civilian police or fire departments colloquially refer to members of the public as civilians.

Semiconductor Gas Sensors

Semiconductor materials include metal oxides, conducting polymers, carbon nanotubes, and 2D materials. Metal oxides are most often the first choice due to their ease of fabrication, low cost, high sensitivity, and stability. Some of their disadvantages are low selectivity and high operating temperature. Conducting polymers have the advantage of a low operating temperature and can detect many organic vapors. They are flexible but affected by humidity. Carbon nanotubes are chemically and mechanically stable and are sensitive towards NO and NH3, but need dopants or modifications to sense other gases. Graphene, transition metal chalcogenides, boron nitride, transition metal carbides/nitrides, metal organic frameworks, and metal oxide nanosheets as 2D materials represent gas-sensing materials of the future, especially in medical devices, such as breath sensing.

Information Technology

Information technology (IT) is the use of computers to create, process, store, retrieve, and exchange all kinds of data and information. IT is typically used within the context of business operations as opposed to personal or entertainment technologies. IT forms part of information and communications technology (ICT). An information technology system (IT system) is generally an information system, a communications system, or, more specifically speaking, a computer system — including all hardware, software, and peripheral equipment — operated by a limited group of IT users. Although humans have been storing, retrieving, manipulating, and communicating information since the earliest writing systems were developed, the term information technology in its modern sense first appeared in a 1958 article published in the Harvard Business Review; authors Harold J. Leavitt and Thomas L. Whisler commented that "the new technology does not yet have a single established name. We shall call it information technology (IT)." Their definition consists of three categories: techniques for processing, the application of statistical and mathematical methods to decision-making, and the simulation of higher-order thinking through computer programs. The term is commonly used as a synonym for computers and computer networks, but it also encompasses other information distribution technologies such as television and telephones. Several products or services within an economy are associated with information technology, including computer hardware, software, electronics, semiconductors, internet, telecom equipment, and e-commerce.[lower-alpha 1] Based on the storage and processing technologies employed, it is possible to distinguish four distinct phases of IT development: pre-mechanical (3000 BC — 1450 AD), mechanical (1450—1840), electromechanical (1840—1940), and electronic (1940 to present). This article focuses on the most recent period (electronic). Information technology is also a branch of computer science, which can be defined as the overall study of procedure, structure, and the processing of various types of data. As this field continues to evolve across the world, the overall priority and importance has also grown, which is where we begin to see the introduction of computer science-related courses in K-12 education. However, concerns have been raised about this fact that most schools are lacking advanced-placement courses in this field.

Solar Architecture in Energy Engineering

Solar Architecture represents the confluence of the two disciplines of energy engineering and architecture. The concept of Solar Architecture defines a decision-making process to select, design, deploy, and operate solar energy-enabled solutions for environments where solar energy resources are part of the energy mix. The principles of Solar Architecture include maximizing solar energy harvesting from solution’s surfaces with a positive balance of energy, carbon, and cost provided by the solution. Solar Architecture application selection is built on two major cornerstones, features and groups, defining the best options in energy engineering of a solar solution. Solar surfaces are key to solar architecture. They are the “heart”, and balance-of-system components are the “muscles” of solar solutions. Addressing energy losses in photovoltaic, solar to thermal, and solar to chemical energy conversion allows for increasing energy harvesting yield. Life Cycle Assessment and solar energy harvesting methodologies based on solar surface characteristics define Solar Architecture Balance. This balance allows for defining energy, carbon, and cost return on investment for solar solutions and selecting the best solution for related assets/environment.

Kādambari is a romantic novel in Sanskrit. It was substantially composed by Bāṇabhaṭṭa in the first half of the 7th century CE, who did not survive to see it through completion. The novel was completed by Banabhatta's son Bhushanabhatta, according to the plan laid out by his late father. It is conventionally divided into Purvabhaga (earlier part) written by Banabhatta, and Uttarabhaga (latter part) by Bhushanabhatta. (An alternate tradition gives the son's name as Pulindabhatta.) The standard editions of the original Sanskrit text are by Peterson and Kane. There are translations into English by Kale, Layne and Ridding; and an abridgement into Gujarati by Bhalan (edited by Keshavlal Dhruv). This novel has an extremely intricate plot which is difficult to summarize concisely. Its central thread is that of a romantic attachment (and eventual union) between the hero Chandrapeeda and the heroine Kadambari. However, there are several competing subplots; indeed, the heroine does not make her appearance until past the midpoint. Many of the characters appear in multiple incarnations, some as humans and some as demigods or animals. The narration proceeds in a succession of nested frames; a large part of it is a retelling by a parrot of a story which was told to it by a sage. The latter story also contains several instances of one character relating a sub-story to another character. The plot has probably been adapted from the story of King Sumanas from Gunadhya's Brihatkatha (a conjectural collection of stories in the extinct Paishachi language). This story also appears in Somadeva's Kathasaritsagara (which is believed to be a Sanskrit precis of Gunadhya's work). This work can be plausibly claimed to be one of the first novels in the world; making due allowance for the ambiguities of such a classification. In fact, two modern Indian languages (Kannada and Marathi) use 'kadambari' as a generic term for a romance or a novel. Apart from the Kadambari, Banabhatta is also the author of Harshacharita, a biography of his patron king Harshavardhana. It is this circumstance which allows one to date the author with a reasonable degree of certainty.

Interslavic Language

Interslavic (Medžuslovjansky; Меджусловјанскы) is a zonal constructed language based on the Slavic languages. Its purpose is to facilitate communication between representatives of different Slavic nations, as well as to allow people who do not know any Slavic language to communicate with Slavs by being understandable to most, if not all Slavic speakers without them having to learn the language themselves. For Slavs it can fulfill an educational role as well. Interslavic can be classified as a semi-constructed language. It is essentially a modern continuation of Old Church Slavonic, but also draws on the various improvised language forms Slavs have been using for centuries to communicate with Slavs of other nationalities, for example in multi-Slavic environments and on the Internet, providing them with a scientific base. Thus, both grammar and vocabulary are based on the commonalities between the Slavic languages, and non-Slavic elements are avoided. Its main focus lies on instant understandability rather than easy learning, a balance typical for naturalistic (as opposed to schematic) languages. Precursors of Interslavic have a long history and predate constructed languages like Volapük and Esperanto by centuries: the oldest description, written by the Croatian priest Juraj Križanić, goes back to the years 1659–1666. In its current form, Interslavic was created in 2006 under the name Slovianski. In 2011, Slovianski underwent a thorough reform and merged with two other projects, simultaneously changing its name to "Interslavic", a name that was first proposed by the Czech Ignác Hošek in 1908. Interslavic can be written using the Latin and the Cyrillic alphabets.

Flux-Modulated Permanent Magnet Machines

High torque density is a desirable feature of electrical machines used in traction applications, such as electric vehicle (EV)/hybrid electric vehicle (HEV) propulsion, wind turbines, more electric air-crafts, etc. The flux-modulated permanent magnet (FMPM) machine is considered as one of the most promising candidates to achieve high torque density. The incorporated gearing effect is ideal in reducing the rotating speed and amplifying the output torque of the FMPM machines.
