What's the difference between cascade and tier?

Cascade


Definition:

  • (n.) A fall of water over a precipice, as in a river or brook; a waterfall less than a cataract.
  • (v. i.) To fall in a cascade.
  • (v. i.) To vomit.

Example Sentences:

  • (2) The following model is suggested: exogenous ATP interacts with a membrane receptor in the presence of Ca2+, a cascade of events occurs which mobilizes intracellular calcium, thereby increasing the cytosolic free Ca2+ concentration which consequently opens the calcium-activated K+ channels, which then leads to a change in membrane potential.

  • (13) The cyclic adenosine nucleotide pathway is turned off by kinase A activity, whereas the inositol trisphosphate cascade is terminated by kinase C. The data support the concept that desensitization of odorant responses involves phosphorylation of key elements in the transduction cascade.
  • (14) These hormonal responses trigger a cascade of metabolic adjustments leading to catabolism and substrate mobilization in the postoperative period.
  • (15) The series filter model is compatible with a simply physical model consisting of cascaded chemical reactions whose forward rate constants are reciprocals of the filter time constants, whose reverse rate constants are negligible, and in which the concentration of an intermediate product controls membrane current.
  • (16) E capture IC via complement receptors, type 1 (CR1) which can bind to C3b and C4b ligand sites generated on IC during activation of the complement cascade.

  • (19) Component of the cascade model represented adventitia and media layers of the wall.
  • (20) These data suggest that sCR1 inhibits the Arthus reaction by interrupting the activation of the C cascade, hence limiting the detrimental immune complex-induced tissue damage in vivo.

Tier


Definition:

  • (n.) One who, or that which, ties.
  • (n.) A chold's apron covering the upper part of the body, and tied with tape or cord; a pinafore.
  • (v. t.) A row or rank, especially one of two or more rows placed one above, or higher than, another; as, a tier of seats in a theater.

Example Sentences:

  • (1) Mike Ashley told Lee Charnley that maybe he could talk with me last week but I said: ‘Listen, we cannot say too much so I think it’s better if we wait.’ The message Mike Ashley is sending is quite positive, but it was better to talk after we play Tottenham.” Benítez will ask Ashley for written assurances over his transfer budget, control of transfers and other spheres of club autonomy, but can also reassure the owner that the prospect of managing in the second tier holds few fears for him.
  • (2) In a triple tier configuration, females concentrated 66% of their travel on the top tier.

  • (7) A new, two-tier system for biotyping Salmonella typhimurium gives a finer and more reliable differentiation of strains than the Kristensen scheme and is capable of future extension by the addition of new types and new tests.

  • (9) It also represents the legalisation of a two-tiered system of tenants' rights – those who can afford to have rights and those who can't."
  • (10) Instead it said that the changing of the settings – which previously required users to navigate through up to 150 different settings to control who could see their data, to a simpler four-tiered version plus a "customise" option – was "merely a red herring".
  • (11) It's a pacey device, and one that serves the game-show content of the novel, and this is a good book; mid-tier King.
