Videos Data Augmentation for Deep Learning Models
In most Computer Vision applications, Deep Learning models achieve state-of-the-art performances. One drawback of Deep Learning is the large amount of data needed to train the models. Unfortunately, in many applications, data are difficult or expensive to collect. Data augmentation can alleviate the problem, generating new data from a smaller initial dataset. Geometric and color space image augmentation methods can increase accuracy of Deep Learning models but are often not enough. More advanced solutions are Domain Randomization methods or the use of simulation to artificially generate the missing data. Data augmentation algorithms are usually specifically designed for single images. Most recently, Deep Learning models have been applied to the analysis of video sequences.

Prime Time Access Rule (US)
The Prime Time Access Rule (PTAR) was a broadcasting regulation that was instituted in the United States by the Federal Communications Commission (FCC) in 1970 to restrict the amount of network programming that a local television station either owned-and-operated or affiliated with a television network can air during "prime time". This rule was repealed by the FCC in 1996.

Social Cohesion: Definitions, Causes and Consequences
Viewed as the glue that binds societies, social cohesion is considered an essential ingredient to address common societal challenges. Definitions and associated conceptual frameworks usually summarise social cohesion as collective attributes and behaviours characterised by positive social relations, a sense of identification or belonging, and an orientation towards the common good. However, there are a large variety of definitions, and disagreement exists about what constitutes the core components, causes and consequences of social cohesion.

MIDAS Technical Analysis
In finance, MIDAS (an acronym for Market Interpretation/Data Analysis System) is an approach to technical analysis initiated in 1995 by the physicist and technical analyst Paul Levine, PhD, and subsequently developed by Andrew Coles, PhD, and David Hawkins in a series of articles and the book MIDAS Technical Analysis: A VWAP Approach to Trading and Investing in Today's Markets. Latterly, several important contributions to the project, including new MIDAS curves and indicators, have been made by Bob English, many of them published in the book. Paul Levine's initial MIDAS work and the new MIDAS approaches developed in the book and other publications by Coles, Hawkins, and English have been taught at university level and are currently the subject of independent study intended for academic publication. The same MIDAS techniques have also been widely implemented as part of private trader and hedge fund strategies. The MIDAS curves and indicators developed by Levine, Coles, Hawkins, and English have also been commercially developed by an independent trading software company for the Ninja Trader trading platform, while individual curves and indicators have been officially coded by developers of a large number of trading platforms, including Metastock, TradeStation, and eSignal. The new MIDAS curves and indicators are in line with the accomplished MIDAS goal of developing an independent approach to financial market analysis with unique standalone indicators available for every type of market environment while also offering information not available from other technical analysis systems.

Batavia (Ship)
Batavia (Dutch pronunciation: [baːˈtaːviaː] (listen)) was a ship of the Dutch East India Company (VOC). It was built in Amsterdam, Dutch Republic, in 1628, and armed with 24 cast-iron cannons and a number of bronze guns. Batavia was shipwrecked on her maiden voyage, and was made famous by the subsequent mutiny and massacre that took place among the survivors. A twentieth-century replica of the ship is also called the Batavia and can be visited in Lelystad, Netherlands.

Metal-Organic Frameworks
Metal-organic frameworks represent a porous class of materials that are build up from metal ions or oligonuclear metallic complexes and organic ligands. They can be considered as sub-class of coordination polymers and can be extended into one-dimension, two-dimensions, and three-dimensions. Depending on the size of the pores, MOFs are divided into nanoporous, mesoporous, and macroporous items. The latter two are usually amorphous. MOFs display high porosity, a large specific surface area, and high thermal stability due to the presence of coordination bonds. The pores can incorporate neutral molecules, such as solvent molecules, anions, and cations, depending on the overall charge of the MOF, gas molecules, and biomolecules. The structural diversity of the framework and the multifunctionality of the pores render this class of materials as candidates for a plethora of environmental and biomedical applications and also as catalysts, sensors, piezo/ferroelectric, thermoelectric, and magnetic materials.

Non-Covalent Interactions
A non-covalent interaction differs from a covalent bond in that it does not involve the sharing of electrons, but rather involves more dispersed variations of electromagnetic interactions between molecules or within a molecule. The chemical energy released in the formation of non-covalent interactions is typically on the order of 1-5 kcal/mol (1000–5000 calories per 6.02 x 10^23 molecules). Non-covalent interactions can be classified into different categories, such as electrostatic, π-effects, van der Waals forces, and hydrophobic effects. Non-covalent interactions are critical in maintaining the three-dimensional structure of large molecules, such as proteins and nucleic acids. In addition, they are also involved in many biological processes in which large molecules bind specifically but transiently to one another (see the properties section of the DNA page). These interactions also heavily influence drug design, crystallinity and design of materials, particularly for self-assembly, and, in general, the synthesis of many organic molecules. Intermolecular forces are non-covalent interactions that occur between different molecules, rather than between different atoms of the same molecule.

Minister President (Germany)
The Minister President (Ministerpräsident) is the head of state and government in thirteen of Germany sixteen states. In the three states of Berlin, Free Hanseatic City of Bremen and Free and Hanseatic City of Hamburg the heads of the state hold different titles: In the since-1952 defunct states of Baden and Württemberg-Hohenzollern the heads of state held the title State President (Staatspräsident). Nevertheless, in Germany it is common practice, to call all sixteen heads of the states ministers president if they are referred to collectively. For example, the regular meetings of the sixteen office-holders are called Conference of Ministers President (Ministerpräsidentenkonferenz).

Innovative Preservation Methods Applied to Fish Products
Fish products are highly perishable, requiring proper processing to maintain their quality and safety during the entire storage. Different from traditional methods used to extend the shelf-life of these products (smoking, salting, marinating, icing, chilling, freezing, drying, boiling, steaming, etc.), in recent years, some alternative methods (non-thermal atmospheric plasma (NTAP), pulsed electric fields (PEF), pulsed light (PL), ultrasounds (US) and electrolyzed water (EW)) have been proposed as innovative processing technologies able to guarantee the extension of their shelf-life while minimally affecting their organoleptic properties.

Mimusops zeyheri
Many African countries are endowed with rich biodiversity with enormous nutritional and economic prospects, but the majority of these resources are not fully harnessed. Exploring these neglected resources, for example, the Transvaal red milkwood tree [(Mimusops zeyheri) Sond. family: Sapotaceae] is of paramount importance for food and nutritional security as well as economic prosperity. This review provides a critical appraisal of the nutritional and health benefits as well as the economic potential of Mimusops zeyheri. The plant is known for its diverse uses among rural communities. In folk medicine, the decoction from the bark and leaves of Mimusops zeyheri are used for treating wounds and ulcers, while the root is used as an infusion taken to treat candidiasis and other health issues. The nutritional profile of the fruit tree is similar to popular exotic fruits and richer in vitamin C when compared to guava and orange. Mimusops zeyheri is a rich source of vitamins, protein, and fatty acids. Based on the rich chemical pool, especially in the fruit and seeds, it has the potential to provide an accessible, readily available, and affordable enriched functional food with valuable health benefits. However, the successful exploration of Mimusops zeyheri for food security and sustainability requires multidisciplinary research. This will help achieve the envisaged food-nutrition security and poverty alleviation potential of the plant, especially among local communities.

Resveratrol in Kidney Disease
Different diseases and disorders that affect the kidneys include, but are not limited to, glomerulonephritis, diabetic nephropathy, polycystic kidney disease, kidney stones, renal fibrosis, sepsis, and renal cell carcinoma. Kidney disease tends to develop over many years, making it difficult to identify until much later when kidney function is severely impaired and undergoing kidney failure. Epidemiological studies have suggested that a diet rich in fruits and vegetables is associated with health benefits including protection against kidney disease and renal cancer. Resveratrol, a polyphenol found in grapes and berries, has been reported to have antioxidant, anti-inflammatory, antidiabetic, hepatoprotective, neuroprotective, and anti-cancer properties.

Autonomous Vehicles
An Autonomous Vehicle (AV), or a driverless car, or a self-driving vehicle is a car, bus, truck, or any other vehicle that is able to drive from point A to point B and perform all necessary driving functions, without any human intervention. An Autonomous Vehicle is normally equipped with different types of sensors to perceive the surrounding environment, including Normal Vision Cameras, Infrared Cameras, RADAR, LiDAR, and Ultrasonic Sensors.  An autonomous vehicle should be able to detect and recognise all type of road users including surrounding vehicles, pedestrians, cyclists, traffic signs, road markings, and can segment the free spaces, intersections, buildings, and trees to perform a safe driving task.  Currently, no realistic prediction expects we see fully autonomous vehicles earlier than 2030.

Robot Bionic Vision Technologies
The visual organ is important for animals to obtain information and understand the outside world; however, robots cannot do so without a visual system. At present, the vision technology of artificial intelligence has achieved automation and relatively simple intelligence; however, bionic vision equipment is not as dexterous and intelligent as the human eye. At present, robots can function as smartly as human beings; however, existing reviews of robot bionic vision are still limited. Robot bionic vision has been explored in view of humans and animals’ visual principles and motion characteristics.
