  2. Notch signaling pathway - Wikipedia

    en.wikipedia.org/wiki/Notch_signaling_pathway

    Notch-mediated juxtacrine signal between adjacent cells Notch signaling steps. The Notch signaling pathway is a highly conserved cell signaling system present in most animals. [1] Mammals possess four different notch receptors, referred to as NOTCH1, NOTCH2, NOTCH3, and NOTCH4. [2] The notch receptor is a single-pass transmembrane receptor protein.

  3. Notch (engineering) - Wikipedia

    en.wikipedia.org/wiki/Notch_(engineering)

    Charpy test sample with a notch. In mechanical engineering and materials science, a notch refers to a V-shaped, U-shaped, or semi-circular defect deliberately introduced into a planar material. In structural components, a notch causes a stress concentration which can result in the initiation and growth of fatigue cracks.

  4. Notch proteins - Wikipedia

    en.wikipedia.org/wiki/Notch_proteins

    Notch family members play a role in a variety of developmental processes by controlling cell fate decisions. The Notch signaling network is an evolutionarily conserved intercellular signaling pathway that regulates interactions between physically adjacent cells.

  5. Juxtacrine signalling - Wikipedia

    en.wikipedia.org/wiki/Juxtacrine_signalling

    Notch-mediated juxtacrine signal between adjacent cells. In biology, juxtracrine signalling (or contact-dependent signalling) is a type of cell–cell or cell–extracellular matrix signalling in multicellular organisms that requires close contact. In this type of signalling, a ligand on one surface binds to a receptor on another adjacent surface.

  6. Somite - Wikipedia

    en.wikipedia.org/wiki/Somite

    The Notch system, as part of the clock and wavefront model, forms the boundaries of the somites. DLL1 and DLL3 are Notch ligands, mutations of which cause various defects. Notch regulates HES1, which sets up the caudal half of the somite. Notch activation turns on LFNG which in turn inhibits the Notch receptor. Notch activation also turns on ...

    en.wikipedia.org/wiki/Somitogenesis

    For example, frogs have approximately 10, humans have 37, chicks have 50, mice have 65, and snakes have more than 300, up to about 500. Somite number is unaffected by changes in the size of the embryo through experimental procedure.

  9. Passive radiator (speaker) - Wikipedia

    en.wikipedia.org/wiki/Passive_radiator_(speaker)

    Although the frequency response of a passive radiator will be similar to that of a ported cabinet, the system low-frequency roll-off will be slightly steeper (5th-order rather than 4th-order), due to a notch (dip) in the frequency response caused by the V ap (compliance or stiffness) of the passive radiator. This notch occurs at the passive ...
