An optical waveguide is a physical structure that guides electromagnetic waves in the optical spectrum. Common types of optical waveguides include optical fiber and rectangular waveguides. Optic...
An optical amplifier is a device that amplifies an optical signal directly, without the need to first convert it to an electrical signal. An optical amplifier may be thought of as a laser without a...
Mortar is a workable paste used to bind building blocks such as stones, bricks, and concrete masonry units together, fill and seal the irregular gaps between them, and sometimes add decorative colo...
In enzymology, a 2,5-didehydrogluconate reductase (EC 1.1.1.274) is an enzyme that catalyzes the chemical reaction 2-dehydro-D-gluconate + NADP+ \rightleftharpoons 2,5-didehydro-D-gluconate + NA...
Automatic label placement, sometimes called text placement or name placement, comprises the computer methods of placing labels automatically on a map or chart. This is related to the typographic de...
Human DNA topoisomerase I (Top1) is an essential enzyme that relaxes DNA supercoiling during replication and transcription. Top1 generates DNA single-strand breaks that allow rotation of the cleave...
An analgesic, or painkiller, is any member of the group of drugs used to achieve analgesia — relief from pain. The word analgesic derives from Greek ἀν-, "without", and ἄλγος, "pain".
Topoisomerase inhibitors are agents designed to interfere with the action of topoisomerase enzymes[1] (topoisomerase I and II), which are enzymes that control the changes in DNA structure[2] by cat...
Itch (Latin: pruritus) is a sensation that causes the desire or reflex to scratch. Itch has resisted many attempts to classify it as any one type of sensory experience. Modern science has shown tha...
Salicylic acid (SA) is a phenolic phytohormone and is found in plants with roles in plant growth and development, photosynthesis, transpiration, ion uptake and transport. SA also induces specific c...
Distributed computing is a field of computer science that studies distributed systems. A distributed system is a software system in which components located on networked computers communicate and c...
Piezoelectric composite
Relatively short fragments of DNA, RNA, and modified oligonucleotides are also synthesized by the solid-phase method. Although oligonucleotides can be synthesized in a flask, they are almost always...
In computer science and electrical engineering, speech recognition (SR) is the translation of spoken words into text. It is also known as "automatic speech recognition" (ASR), "computer speech reco...
3D printing (or additive manufacturing, AM) is any of various processes used to make a three-dimensional object.[1] In 3D printing, additive processes are used, in which successive layers of materi...
An excimer[1] (originally short for excited dimer) is a short-lived dimeric or heterodimeric molecule formed from two species, at least one of which has completely filled valence shell by electrons...
The continuous flow stirred-tank reactor (CSTR), also known as vat- or backmix reactor, is a common ideal reactor type in chemical engineering. A CSTR often refers to a model used to estimate the k...
