Agrivoltaic System
Agrivoltaic systems (AVS) offer a symbiotic strategy for co-location sustainable renewable energy and agricultural production. This is particularly important in densely populated developing and developed countries, where renewable energy development is becoming more important; however, profitable farmland must be preserved. As emphasized in the Food-Energy-Water (FEW) nexus, AVS advancements should not only focus on energy management, but also agronomic management (crop and water management).

Testing Effect
The testing effect is the finding that long-term memory is often increased when some of the learning period is devoted to retrieving the to-be-remembered information. The effect is also sometimes referred to as retrieval practice, practice testing, or test-enhanced learning. Retrieval practice may be the best way to refer to the testing effect because the benefits of retrieval-related testing are not limited to tests. It can be more broad, including tools like flash cards and quizzes. The testing effect on memory should be distinguished from more general practice effects, defined in the APA Dictionary of Psychology (2007) as "any change or improvement that results from practice or repetition of task items or activities." The term testing effect is also sometimes used in a more general sense; The Oxford Dictionary of Psychology (2003) defines a testing effect as "any effect of taking tests on the respondents, a typical example being test sophistication." Whereas psychologists who develop tests for personality and intelligence want to avoid practice effects, cognitive psychologists working with educators have begun to understand how to take advantage of tests—not as an assessment tool, but as a teaching/learning tool. It is useful for people to test their knowledge of the to-be-remembered material during the learning process, instead of only reading or otherwise passively studying the material. For example, a student can use flashcards to self-test and receive feedback as they study. The testing effect provides a larger benefit to long-term memory when the tested material is difficult enough to require effort, the rate of retrieval success is high, and feedback with correct answers is given after testing. The testing effect is activated by active recall.

High Dynamic Range (Display and Formats)
High Dynamic Range (HDR) is a video and image technology that improves the way light is represented. It overcomes the limits of the standard format that is named Standard Dynamic Range (SDR). HDR offers the possibility to represent substantially brighter highlights, darker shadows, more details in both sides and more colorful colors than what was previously possible. HDR do not increase display's capabilities, rather it allows to make better use of displays that have high brightness, contrast and colors capabilities. Not all HDR displays have the same capabilities and HDR contents will thus look different depending the display used. HDR emerged first for videos in 2014. HDR10, HDR10+, Dolby Vision and HLG are common HDR formats. Some still pictures formats do also support HDR.

Records Continuum Model
The Records Continuum Model (RCM) was created in the 1990s by Monash University academic Frank Upward with input from colleagues Sue McKemmish and Livia Iacovino as a response to evolving discussions about the challenges of managing digital records and archives in the discipline of Archival Science. The RCM was first published in Upward’s 1996 paper "Structuring the Records Continuum – Part One: Postcustodial principles and properties". Upward describes the RCM within the broad context of a continuum where activities and interactions transform documents into records, evidence and memory that are used for multiple purposes over time. Upward places the RCM within a post-custodial, postmodern and structuration conceptual framework. Australian academics and practitioners continue to explore, develop and extend the RCM and records continuum theory, along with international collaborators, via the Records Continuum Research Group (RCRG) at Monash University.

Brainstem Encephalitis
Brainstem encephalitis refers to inflammatory diseases affecting the midbrain, pons, and medulla oblongata. The causes of brainstem encephalitis include infections, autoimmune diseases, and paraneoplastic syndromes. Listeria is a common etiology of infectious rhombencephalitis. The trigeminal nerve has been proposed as a pathway through which Listeria monocytogenes reaches the brainstem after entering damaged oropharyngeal mucosa or periodontal tissues. Listeria monocytogenes may also invade the brainstem along the vagus nerve after it infects enteric neurons in the walls of the gastrointestinal tract.

Tyrannosaurus
Tyrannosaurus is a genus of large theropod dinosaur. The species Tyrannosaurus rex (rex meaning "king" in Latin), often called T. rex or colloquially T-Rex, is one of the best represented theropods. Tyrannosaurus lived throughout what is now western North America, on what was then an island continent known as Laramidia. Tyrannosaurus had a much wider range than other tyrannosaurids. Fossils are found in a variety of rock formations dating to the Maastrichtian age of the Upper Cretaceous period, 68 to 66 million years ago. It was the last known member of the tyrannosaurids and among the last non-avian dinosaurs to exist before the Cretaceous–Paleogene extinction event. Like other tyrannosaurids, Tyrannosaurus was a bipedal carnivore with a massive skull balanced by a long, heavy tail. Relative to its large and powerful hind limbs, the forelimbs of Tyrannosaurus were short but unusually powerful for their size, and they had two clawed digits. The most complete specimen measures up to 12.3–12.4 m (40.4–40.7 ft) in length; however, according to most modern estimates, T. rex could grow to lengths of over 12.4 m (40.7 ft), up to 3.66–3.96 m (12–13 ft) tall at the hips, and 8.87 metric tons (9.78 short tons) in body mass. Although other theropods rivaled or exceeded Tyrannosaurus rex in size, it is still among the largest known land predators and is estimated to have exerted the strongest bite force among all terrestrial animals. By far the largest carnivore in its environment, Tyrannosaurus rex was most likely an apex predator, preying upon hadrosaurs, juvenile armored herbivores like ceratopsians and ankylosaurs, and possibly sauropods. Some experts have suggested the dinosaur was primarily a scavenger. The question of whether Tyrannosaurus was an apex predator or a pure scavenger was among the longest debates in paleontology. Most paleontologists today accept that Tyrannosaurus was both an active predator and a scavenger. Specimens of Tyrannosaurus rex include some that are nearly complete skeletons. Soft tissue and proteins have been reported in at least one of these specimens. The abundance of fossil material has allowed significant research into many aspects of its biology, including its life history and biomechanics. The feeding habits, physiology, and potential speed of Tyrannosaurus rex are a few subjects of debate. Its taxonomy is also controversial, as some scientists consider Tarbosaurus bataar from Asia to be a second Tyrannosaurus species, while others maintain Tarbosaurus is a separate genus. Several other genera of North American tyrannosaurids have also been synonymized with Tyrannosaurus. As the archetypal theropod, Tyrannosaurus has been one of the best-known dinosaurs since the early 20th century and has been featured in film, advertising, postal stamps, and many other media.

Food Heritage
The entry explores the concept of food heritage, focusing mainly on the anthropological, geographical, and sociological debate. Although the review identifies some conceptualisations that frame heritage in the food and gastronomic domains, it also shows the high degree of fragmentation of the debate. In so doing, it sheds light on how the concept of food heritage from a theoretical point of view is still in progress.

Manila Galleon
The Manila Galleons (Spanish: Galeón de Manila; Filipino: Galyon ng Maynila) were Spain trading ships which for two-and-a-half centuries linked the Spanish Captaincy General of the Philippines with Mexico across the Pacific Ocean, making one or two round-trip voyages per year between the ports of Acapulco and Manila, which were both part of New Spain. The name of the galleon changed to reflect the city that the ship sailed from. The term Manila galleon can also refer to the trade route itself between Acapulco and Manila, which lasted from 1565 to 1815. The Manila galleons sailed the Pacific for 250 years, bringing to the Americas cargoes of luxury goods such as spices and porcelain in exchange for New World silver. The route also fostered cultural exchanges that shaped the identities and culture of the countries involved. The Manila galleons were also (somewhat confusingly) known in New Spain as La Nao de la China ("The China Ship") on their voyages from the Philippines because they carried mostly Chinese goods, shipped from Manila. The Spanish inaugurated the Manila galleon trade route in 1565 after the Augustinian friar and navigator Andrés de Urdaneta pioneered the tornaviaje or return route from the Philippines to Mexico. Urdaneta and Alonso de Arellano made the first successful round trips that year. The trade using "Urdaneta's route" lasted until 1815, when the Mexican War of Independence broke out. In 2015 the Philippines and Mexico began preparations for the nomination of the Manila-Acapulco Galleon Trade Route in the UNESCO World Heritage List, with backing from Spain. Spain has also suggested the tri-national nomination of the Archives on the Manila-Acapulco Galleons in the UNESCO Memory of the World Register.

Pre-Existence
Pre-existence, preexistence, beforelife, or premortal existence refers to the belief that each individual human soul existed before mortal conception, and at some point before birth enters or is placed into the body. Concepts of pre-existence can encompass either the belief that the soul came into existence at some time prior to conception or the belief that the soul is eternal. Alternative positions are traducianism and creationism, which both hold that the individual human soul does not come into existence until conception. It is to be distinguished from preformation, which is about physical existence and applies to all living things. Ancient Greek thought and Islam affirm pre-existence, but it is generally denied in Christianity.

Stress–Energy Tensor
The stress–energy tensor, sometimes called the stress–energy–momentum tensor or the energy–momentum tensor, is a tensor quantity in physics that describes the density and flux of energy and momentum in spacetime, generalizing the stress tensor of Newtonian physics. It is an attribute of matter, radiation, and non-gravitational force fields. This density and flux of energy and momentum are the sources of the gravitational field in the Einstein field equations of general relativity, just as mass density is the source of such a field in Newtonian gravity.

Adaptive Reuse of Architectural Heritage
       Significant architectural and historical monuments become an important point of reference for the local population, increasing their sense of security, and act as a factor shaping social identity. An effort to preserve relevant objects in a city is therefore important both for retaining its unique features and for strengthening the local community. A significant role plays here the adaptive reuse of architectural heritage, which allows for the preservation of architectural objects that are important to the local community, promoting the integrity and historical continuity of the city while restoring the objects’ functional and economic value.         The introduction of a new function in architectural heritage is not only an important impulse for the tangible regeneration of urban tissue, but can also help to reconstruct the image and identity of a city. The local cultural and architectural heritage plays a significant role in the process leading to the creation of positive references and elimination of negative connotations related to an economic or social crisis. These remain an important part of the history of a city and, at the same time, its significance may be reimagined and shown in a new context, that relates to the present day. As a result, artefacts of the past gain new meanings, which are subject to a different, contemporary interpretation through the prism of current needs and ideas. Objects or even groups of objects from the past are being consciously taken into consideration in the activities currently undertaken. The contemporary scale of the phenomenon and complexity of the issues concerning the adaptive reuse of architectural heritage are a consequence of the multi-faceted transformations that have taken place in recent decades in the social, cultural and economic spheres, and, consequently, the contemporary understanding of the role and significance of the architectural heritage.
