Gemma (botany)
A gemma (English plural ''gemmas'', Latin plural ''gemmae'') is a single cell, or a mass of cells, or a modified bud of tissue, that detaches from the parent and develops into a new individual. This type of asexual reproduction is referred to as fragmentation. It is a means of asexual propagation in plants. These structures are commonly found in fungi, algae, liverworts and mosses, but also in some flowering plants such as pygmy sundews and some species of butterworts. Vascular plants have many other methods of asexual reproduction including bulbils and turions. In mosses and liverworts The production of gemmae is a widespread means of asexual reproduction in both liverworts and mosses. In liverworts such as ''Marchantia'', the flattened plant body or thallus is a haploid gametophyte with gemma cups scattered about its upper surface. The gemma cups are cup-like structures containing gemmae. The gemmae are small discs of haploid tissue, and they directly give rise to new ...

Veneridae
The Veneridae or venerids, common name: Venus (mythology), Venus clams, are a very large family of minute to large, saltwater clams, marine bivalve molluscs. Over 500 living species of venerid bivalves are known, most of which are edible, and many of which are exploited as food sources. Many of the most important edible species are commonly known (in the USA) simply as "clams". Venerids make up a significant proportion of the world fishery of edible bivalves. The family includes some species that are important commercially, such as (in the USA) the hard clam or quahog, ''Mercenaria mercenaria''. Taxonomy The classification within the family Veneridae has been controversial at least since the 1930s. Molecular approaches show that much of this traditional classification is unnatural. Some common species have been moved between genera (including genera in different subfamilies) because of repeated attempts to bring a more valid organization to the classification or Taxonomy (biol ...

Gemma Gemma
The amethyst gem clam (''Gemma gemma'') is species of very small saltwater clam, a marine bivalve mollusk in the family Veneridae, the Venus clams. It is a small species, reaching a length of only 5 mm. The shell color is whitish or grayish, suffused with purple on both outer and inner surfaces. The species is native to the Atlantic coast of North America, from Labrador to Texas, but it is now also found as an introduced species in some locations on the Pacific The Pacific Ocean is the largest and deepest of Earth's five oceanic divisions. It extends from the Arctic Ocean in the north to the Southern Ocean, or, depending on the definition, to Antarctica in the south, and is bounded by the cont ... coast.

Diacamma
''Diacamma'' is a genus of queenless ants belonging to the subfamily Ponerinae. It is distributed from India to Australia and contains about 24 species. Biology A queen caste does not exist in ''Diacamma''. Unique to this genus, all workers emerge from cocoons with a pair of tiny innervated thoracic appendages (''gemmae'') that are homologous with wings. Mutilation leads to a permanent change in lifetime trajectory, because workers lacking gemmae never mate. This is unlike other queenless ants where workers establish a dominance hierarchy to regulate reproduction. In ''Diacamma'' only one worker retains her gemmae in each colony, she is the gamergate (mated egglaying worker), and she bites off the gemmae of newly emerged workers. Mutilation causes the degeneration of the neuronal connections between the sensory hairs on the gemma's surface and the central nervous system, and this may explain the irreversibility of modifications in individual behaviour.

Gas Phase Electrophoretic Molecular Mobility Analysis
Gas is a state of matter that has neither a fixed volume nor a fixed shape and is a compressible fluid. A ''pure gas'' is made up of individual atoms (e.g. a noble gas like neon) or molecules of either a single type of atom ( elements such as oxygen) or from different atoms ( compounds such as carbon dioxide). A ''gas mixture'', such as air, contains a variety of pure gases. What distinguishes gases from liquids and solids is the vast separation of the individual gas particles. This separation can make some gases invisible to the human observer. The gaseous state of matter occurs between the liquid and plasma states, the latter of which provides the upper-temperature boundary for gases. Bounding the lower end of the temperature scale lie degenerative quantum gases which are gaining increasing attention. High-density atomic gases super-cooled to very low temperatures are classified by their statistical behavior as either Bose gases or Fermi gases. For a comprehensive listing of ...

Gemma (language Model)
Gemini is a family of multimodal large language models (LLMs) developed by Google DeepMind, and the successor to LaMDA and PaLM 2. Comprising Gemini Ultra, Gemini Pro, Gemini Flash, and Gemini Nano, it was announced on December 6, 2023, positioned as a competitor to OpenAI's GPT-4. It powers the chatbot of the same name. In March 2025, Gemini 2.5 Pro Experimental was rated as highly competitive. History Development Google announced Gemini, a large language model (LLM) developed by subsidiary Google DeepMind, during the Google I/O keynote on May 10, 2023. It was positioned as a more powerful successor to PaLM 2, which was also unveiled at the event, with Google CEO Sundar Pichai stating that Gemini was still in its early developmental stages. Unlike other LLMs, Gemini was said to be unique in that it was not trained on a text corpus alone and was designed to be multimodal, meaning it could process multiple types of data simultaneously, including text, images, audio, ...

Alpha Coronae Borealis
Alpha Coronae Borealis (α Coronae Borealis, abbreviated Alpha CrB, α CrB), officially named Alphecca , is an eclipsing binary star in the constellation of Corona Borealis. It is located about 75 light years from the Sun and contains two main sequence stars, one A-type star, class A and one G-type star, class G. Properties Alpha Coronae Borealis is a binary system, its stars orbiting each other in an Eccentricity (orbit), eccentric orbit every 17.36 days. Because the plane of this orbit is inclined at an angle of 88.2° to the line of sight to the Earth, the pair form a detached eclipsing binary system similar to Algol (β Per). The periodic eclipses result in a magnitude variation of +2.21 to +2.32, which is hardly noticeable to the unaided eye. The primary component is a white main sequence star that has a stellar classification of A0V and 2.6 times the Solar mass, mass of the Sun. Estimates of the star's radius range from 2.89 to 3.04 times the Solar radius, radi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

In November, the reward was issued to Hector Martin for his open-source Kinect dr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Italian Submarine Gemma
Italian submarine ''Gemma'' was a built for the Royal Italian Navy (''Regia Marina'') during the 1930s. Her name in Italian means a gemstone or jewel. Design and description The ''Perla''-class submarines were essentially repeats of the preceding . The modifications that were made compared to the boats of the previous series were mostly of upgrade nature. Among them were enlargement of the false tower at the top, more modern engines, installation of a radiogoniometer that could be controlled from inside the ship. Improvements and the installation of new air conditioning equipment meant a slight increase in displacement, and increase in the fuel stowage also increased the autonomy of these boats compared to the previous series.Pollina, p.155 Their designed full load displacement was surfaced and submerged, but varied somewhat depending on the boat and the builder. The submarines were long, had a beam of and a draft of to .Bagnasco, p. 153Pollina, pp.152-153 For surface run ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
