https://en.wikipedia.org/wiki/Calcium%20sulfite | Calcium sulfite, or calcium sulphite, is a chemical compound, the calcium salt of sulfite with the formula CaSO3·x(H2O). Two crystalline forms are known, the hemihydrate and the tetrahydrate, respectively CaSO3·½(H2O) and CaSO3·4(H2O). All forms are white solids. It is most notable as the product of flue-gas desulfuri... |
https://en.wikipedia.org/wiki/DB-2073 | DB-2073 is an alkylresorcinol antibiotic isolated from the broth culture of Pseudomonas sp B-9004. |
https://en.wikipedia.org/wiki/Leucoplast | Leucoplasts ("formed, molded") are a category of plastid and as such are organelles found in plant cells. They are non-pigmented, in contrast to other plastids such as the chloroplast.
Lacking photosynthetic pigments, leucoplasts are not green and are located in non-photosynthetic tissues of plants, such as roots, bul... |
https://en.wikipedia.org/wiki/Intermittent%20control | Intermittent control is a feedback control method which not only explains some human control systems but also has applications to control engineering.
In the context of control theory, intermittent control provides a spectrum of possibilities between the two extremes of continuous-time and discrete-time control: the c... |
https://en.wikipedia.org/wiki/Lactic%20acid | Lactic acid is an organic acid. It has a molecular formula . It is white in the solid state and it is miscible with water. When in the dissolved state, it forms a colorless solution. Production includes both artificial synthesis as well as natural sources. Lactic acid is an alpha-hydroxy acid (AHA) due to the presence ... |
https://en.wikipedia.org/wiki/High-level%20verification | High-level verification (HLV), or electronic system-level (ESL) verification, is the task to verify ESL designs at high abstraction level, i.e., it is the task to verify a model that represents hardware above register-transfer level (RTL) abstract level. For high-level synthesis (HLS or C synthesis), HLV is to HLS as f... |
https://en.wikipedia.org/wiki/Rambutan%20%28cryptography%29 | Rambutan is a family of encryption technologies designed by the Communications-Electronics Security Group (CESG), the technical division of the United Kingdom government's secret communications agency, GCHQ.
It includes a range of encryption products designed by CESG for use in handling confidential (not secret) comm... |
https://en.wikipedia.org/wiki/HKA%20test | The HKA Test, named after Richard R. Hudson, Martin Kreitman, and Montserrat Aguadé, is a statistical test used in genetics to evaluate the predictions of the Neutral Theory of molecular evolution. By comparing the polymorphism within each species and the divergence observed between two species at two or more loci, the... |
https://en.wikipedia.org/wiki/Ultracold%20atom | In condensed matter physics, an ultracold atom is an atom with a temperature near absolute zero. At such temperatures, an atom's quantum-mechanical properties become important.
To reach such low temperatures, a combination of several techniques typically has to be used. First, atoms are trapped and pre-cooled via lase... |
https://en.wikipedia.org/wiki/Shape%20factor%20%28image%20analysis%20and%20microscopy%29 | Shape factors are dimensionless quantities used in image analysis and microscopy that numerically describe the shape of a particle, independent of its size. Shape factors are calculated from measured dimensions, such as diameter, chord lengths, area, perimeter, centroid, moments, etc. The dimensions of the particles ... |
https://en.wikipedia.org/wiki/Data%20hierarchy | Data hierarchy refers to the systematic organization of data, often in a hierarchical form. Data organization involves characters, fields, records, files and so on. This concept is a starting point when trying to see what makes up data and whether data has a structure. For example, how does a person make sense of data ... |
https://en.wikipedia.org/wiki/UEFITool | UEFITool is a software program for reading and modifying EEPROM images that contain an UEFI firmware. Features include the ability to view the flash regions and to extract and import them. |
