Marl
Marl is an earthy material rich in carbonate minerals, clays, and silt. When hardened into rock, this becomes marlstone. It is formed in marine or freshwater environments, often through the activities of algae. Marl makes up the lower part of the cliffs of Dover, and the Channel Tunnel follows these marl layers between France and the United Kingdom. Marl is also a common sediment in post-glacial lakes, such as the marl ponds of the northeastern United States. Marl has been used as a soil conditioner and neutralizing agent for acid soil and in the manufacture of cement. Description Marl or marlstone is a carbonate-rich mud or mudstone which contains variable amounts of clays and silt. The term was originally loosely applied to a variety of materials, most of which occur as loose, earthy deposits consisting chiefly of an intimate mixture of clay and calcium carbonate, formed under freshwater conditions. These typically contain 35–65% clay and 65–35% carbonate. The te ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Marl Lake
A marl lake is a type of alkaline lake whose bottom sediments include large deposits of marl, a mixture of clay and carbonate minerals. The term is particularly applied to lakes that have been dredged or mined for marl, often for manufacturing Portland cement. Marl lakes are found around the Great Lakes of North America, in Britain, and in other areas that were once glaciated. They support distinctive ecological communities that are vulnerable to damage from silting, nutrient pollution, drainage, and invasive species. Description Marl lakes typically are found in areas that were recently glaciated, and they often fill kettle depressions left behind by melting glaciers. Their most distinctive characteristic is that they deposit sediments rich in calcium carbonate. More precisely, a marl lake is a lake in which calcium carbonate makes up at least 50% of the dry weight of the inorganic fraction of the surface sediments. In some lakes, the sediments are almost pure calcium carbona ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Marl Kingdom
is a series of RPGs developed by Nippon Ichi Software. The three main games in the series are '' Rhapsody: A Musical Adventure'', '' Little Princess: Marl Ōkoku no Ningyō Hime 2'', and '' Tenshi no Present: Marl Ōkoku Monogatari''. The first two games were released on the PlayStation, whereas the latter was for the PlayStation 2. Only ''Rhapsody'' was translated to English, and was published by Atlus in 2000. The other two games' scripts have been translated to English by fans. Characteristics Like most Nippon Ichi games, the ''Marl'' games feature bright, anime influenced graphics. All the games use 2D backgrounds and sprites, with the exception of ''Tenshi no Present'', which has 3D backgrounds with 2D sprites. Each of the games were created by Yoshitsuna Kobayashi and feature the artwork of Yoshiharu Nomura, whereas the music was composed by Tenpei Sato, a regular for handling Nippon Ichi games. Sato described ''Rhapsody's'' music as a "complete musical with both solos and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Machine Learning
Machine learning (ML) is a field of inquiry devoted to understanding and building methods that 'learn', that is, methods that leverage data to improve performance on some set of tasks. It is seen as a part of artificial intelligence. Machine learning algorithms build a model based on sample data, known as training data, in order to make predictions or decisions without being explicitly programmed to do so. Machine learning algorithms are used in a wide variety of applications, such as in medicine, email filtering, speech recognition, agriculture, and computer vision, where it is difficult or unfeasible to develop conventional algorithms to perform the needed tasks.Hu, J.; Niu, H.; Carrasco, J.; Lennox, B.; Arvin, F.,Voronoi-Based Multi-Robot Autonomous Exploration in Unknown Environments via Deep Reinforcement Learning IEEE Transactions on Vehicular Technology, 2020.

Multi-agent Reinforcement Learning
] Multi-agent reinforcement learning (MARL) is a sub-field of reinforcement learning. It focuses on studying the behavior of multiple learning agents that coexist in a shared environment. Each agent is motivated by its own rewards, and does actions to advance its own interests; in some environments these interests are opposed to the interests of other agents, resulting in complex group dynamics. Multi-agent reinforcement learning is closely related to game theory and especially repeated games, as well as multi-agent systems. Its study combines the pursuit of finding ideal algorithms that maximize rewards with a more sociological set of concepts. While research in single-agent reinforcement learning is concerned with finding the algorithm that gets the biggest number of points for one agent, research in multi-agent reinforcement learning evaluates and quantifies social metrics, such as cooperation, reciprocity, equity, social influence, language and discrimination.

Marl Slate Formation
The Marl Slate Formation is a geological formation in England. Despite its name, it is mostly dolomite rock. The Marl Slate Formation was formed about 273 to 259 million years ago, during the Guadalupian and Lopingian epochs of the late Permian period of the Earth's geological history. This formation is part of the Zechstein Group of rocks, and is equivalent to the Kupferschiefer of Germany. The Marl Slate Formation contains fossils including the conodont '' Mesogondolella britannica'' and the dorypterid fishes '' Dorypterus'' and ''Lekanichthys'', as well as the gliding reptile '' Weigeltisaurus'' and terrestrial reptile '' Protorosaurus'' The Marl Slate Formation outcrops in County Durham and Yorkshire in north-east England.

Marl Prairie
Marl prairies are wet prairies that allow for a slow seepage of overland water and exist in the Everglades, usually bordering deeper sloughs, and contain low-growth vegetation. Description Marl is loose earthy deposits mixed with clay and calcium carbonate and sits on limestone bedrock. Marl prairies are home to microbes, bacteria, and algae, and serve as an important food source to some fish, tadpoles, and invertebrates. Marl prairies are also thought to be the preferred breeding ground of the endangered Cape Sable Seaside Sparrow.

Western Barred Bandicoot
The Western barred bandicoot (''Perameles bougainville''), also known as the Marl, is a small species of bandicoot; now extinct across most of its former range, the western barred bandicoot only survives on offshore islands and in fenced sanctuaries on the mainland. Description The Western barred bandicoot Is much smaller than its relative the eastern barred bandicoot (''Perameles gunnii''), and is darker in its colouring, which is a grizzled brown. It measures about in length. It has two "bars" across its rump and has a short, tapered tail. It was a solitary and crepuscular hunter, eating insects, spiders, and worms and occasionally tubers and roots. When the bandicoot feels threatened, it typically leaps into the air and then burrows to safety. Taxonomy The first description of the Western barred bandicoot was from a specimen taken at Peron Peninsula in 1817 by naturalists on the ''Uranie''. Populations of the ''Perameles'' species have been referred to by various names, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Marl Mountains
The Marl Mountains are located in the Mojave National Preserve in eastern California in the United States, northeast of the Kelso Mountains. The Marl Mountains lie just east of Kelbaker Road, which connects the town of Baker with the small community of Kelso, California. Like the Beale Mountains to the east, the range is one of the smallest mountain ranges in the nation, and is only about four miles long. The Marl Mountains are often visited by travelers on the historic Mojave Road The Mojave Road, also known as Old Government Road (formerly the Mohave Trail), is a historic route and present day dirt road across what is now the Mojave National Preserve in the Mojave Desert in the United States.
