Analog Signal
An analog signal (American English) or analogue signal (British and Commonwealth English) is any continuous-time signal representing some other quantity, i.e., ''analogous'' to another quantity. For example, in an analog audio signal, the instantaneous signal voltage varies continuously with the pressure of the sound waves. In contrast, a digital signal represents the original time-varying quantity as a sampled sequence of quantized values. Digital sampling imposes some bandwidth and dynamic range constraints on the representation and adds quantization noise. The term ''analog signal'' usually refers to electrical signals; however, mechanical, pneumatic, hydraulic, and other systems may also convey or be considered analog signals. Representation An analog signal uses some property of the medium to convey the signal's information. For example, an aneroid barometer uses rotary position as the signal to convey pressure information. In an electrical signal, the voltage, ...

Root Analogue Dental Implant
A root-analogue dental implant (RAI) – also known as a truly anatomic dental implant, or an anatomical/custom implant – is a medical device to replace one or more roots of a single tooth immediately after dental extraction, extraction. In contrast to common titanium screw type implants, these implants are custom-made to exactly match the extraction socket of the specific patient. Thus there is usually no need for surgery. As the root analogue dental implant matches the dental alveolus (tooth socket) it can only be placed immediately after the tooth extraction. If the tooth has been already lost and the soft and hard tissue is already healed, an RAI can no longer be placed. The basic principle of endosseous implants is a biological process described as osseointegration, in which materials such as titanium or ceramic form an intimate bond to bone. There are no particular differences between the osseointegration of a root analogue implant and a conventional screw type implant. Di ...

Substrate Analog
Substrate analogs (substrate state analogues), are chemical compounds with a chemical structure that resemble the substrate molecule in an enzyme-catalyzed chemical reaction. Substrate analogs can act as competitive inhibitors of an enzymatic reaction. An example is phosphoramidate to the '' Tetrahymena'' group I ribozyme. Other examples of substrate analogs include 5’-adenylyl-imidodiphosphate, a substrate analog of ATP, and 3-acetylpyridine adenine dinucleotide, a substrate analog of NADH. As a competitive inhibitor, substrate analogs occupy the same binding site as its analog, and decrease the intended substrate’s efficiency. The maximum rate (Vmax) remains the same while the intended substrate’s affinity (measured by the Michaelis constant KM) is decreased. This means that less of the intended substrate will bind to the enzyme, resulting in less product being formed. In addition, the substrate analog may also be missing chemical components that allow the enzyme to g ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Structural Analog
A structural analog, also known as a chemical analog or simply an analog, is a chemical compound, compound having a chemical structure, structure similar to that of another compound, but differing from it in respect to a certain component. It can differ in one or more atoms, functional groups, or substructures, which are replaced with other atoms, groups, or substructures. A structural analog can be imagined to be formed, at least theoretically, from the other compound. Structural analogs are often isoelectronicity, isoelectronic. Despite a high chemical similarity, structural analogs are not necessarily functional analog (chemistry), functional analogs and can have very different physical, chemical, biochemical, or pharmacological properties. In drug discovery, either a large series of structural analogs of an initial lead compound are created and tested as part of a structure–activity relationship study or a database is virtual screening, screened for structural analogs of a ...

Functional Analog (chemistry)
In chemistry and pharmacology, functional analogs are chemical compounds that have similar physical, chemical, biochemical, or pharmacological properties. Functional analogs are not necessarily structural analogs with a similar chemical structure. An example of pharmacological functional analogs are morphine, heroin and fentanyl, which have the same mechanism of action, but fentanyl is structurally quite different from the other two with significant variance in dosage. File:Morphin - Morphine.svg, Morphine File:Heroin - Heroine.svg, Heroin File:Fentanyl2DCSD.svg, Fentanyl Fentanyl is a highly potent synthetic piperidine opioid primarily used as an analgesic (pain medication). It is 30 to 50 times more Potency (pharmacology), potent than heroin and 50 to 100 times more potent than morphine. Its primary Medici ...

Analogical Models
Analogical models are a method of representing a phenomenon of the world, often called the "target system" by another, more understandable or analysable system. They are also called dynamical analogies. Two open systems have ''analog'' representations (see illustration) if they are black box isomorphic systems. Explanation A simple type of analogy is one that is based on shared properties; and analogizing is the process of representing information about a particular subject (the ''analogue'' or ''source'' system) by another particular subject (the ''target'' system), in order "to illustrate some particular aspect (or clarify selected attributes) of the primary domain". Analogical models, also called "analog" or "analogue" models, seek the analogous systems that share properties with the target system as a means of representing the world. It is often practicable to construct source systems that are smaller and/or faster than the target system so that one can deduce ''a prior ...

Analog (program)
Analog is a free web log analysis computer program that runs under Windows, macOS, Linux, and most Unix-like operating systems. It was first released on June 21, 1995, by Stephen Turner as generic freeware; the license was changed to the GNU General Public License in November 2004. The software can be downloaded for several computing platforms, or the source code can be downloaded and compiled if desired. Analog has support for 35 languages, and provides the ability to do reverse DNS lookups on log files, to indicate where web site hits originate. It can analyze several different types of web server logs, including Apache, IIS, and iPlanet. It has over 200 configuration options and can generate 32 reports. It also supports log files for multiple virtual hosts. The program is comparable to Webalizer or AWStats, though it does not use as many images, preferring to stick with simple bar charts and lists to communicate similar information. Analog can export reports in a number o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
