Cascade

An artificial waterfall that breaks the water as it flows over stone steps, usually found in a garden setting.

Cascade

 

in landscaping, a natural or artificial waterfall descending over terraced steps. In park architecture cascades are created by building at various levels of bodies of water and of steps and terraces over which the water descends. Examples of famous cascades are those in Italy, in the Villa d’Este in Tivoli (1550–72, architect P. Ligorio) and the Villa Aldobrandini in Frascati (1598–1604, architects G. della Porta and C. Maderna), as well as those in the park in Petrodvorets.

In the figurative sense a cascade is a rapid irrepressible flowof something—for example, words or sounds.

cascade

[ka′skād] (computer science) A series of actions that take place in the course of data processing, each triggered by the previous action in the series. (electricity) An electric-power circuit arrangement in which circuit breakers of reduced interrupting ratings are used in the branches, the circuit breakers being assisted in their protection function by other circuit breakers which operate almost instantaneously. Also known as backup arrangement. (electronics) avalanche (engineering) An arrangement of separation devices, such as isotope separators, connected in series so that they multiply the effect of each individual device. (geology) A landform structure formed by gravity collapse, consisting of a bed that buckles into a series of folds as it slides down the flanks of an anticline. (hydrology) A small waterfall or series of falls descending over rocks. (cell and molecular biology) A molecular system that is capable of self-propagation or amplification. (physics) The emission of a series of photons by a quantum system, such as an atomic nucleus or a laser, in an excited state, accompanying transitions of the system to successively lower excited states, until the system reaches the ground state.

cascade

(compiler)A huge volume of spurious error-messages outputby a compiler with poor error recovery. Too frequently,one trivial syntax error (such as a missing ")" or "}")throws the parser out of synch so that much of the remainingprogram text, whether correct or not, is interpreted asgarbaged or ill-formed.

cascade

(messaging)A chain of Usenet followups, each adding sometrivial variation or riposte to the text of the previous one,all of which is reproduced in the new message; an include war in which the object is to create a sort of communalgraffito.

cascade

(networking)A collection of interconneced networkingdevices, typically hubs, that allows those devices to acttogether as a logical repeater.

cascade

A connected series of devices or images. It often implies that the second and subsequent device takes over after the previous one is used up. For example, cascading tapes in a dual-tape backup system means the second tape is written after the first one is full. In a PC, a second IRQ chip is cascaded to the first, doubling the number of interrupts.

cascade


cascade

 [kas-kād´] a series of steps or stages (as of a physiological process) that, once initiated, continues to the final step because each step is triggered by the preceding one, resulting in amplification of the signal, information, or effect at each stage. In electronics, the term is applied to multiple amplifiers. Examples in biochemistry include blood coagulation and the complement system.coagulation cascade the series of steps beginning with activation of the intrinsic or pathways of coagulation" >extrinsic pathways of coagulation, or of one of the related alternative pathways, and proceeding through the pathway of coagulation" >common pathway of coagulation to the formation of the fibrin clot. The coagulation cascade. This scheme emphasizes the understanding of 1, the importance of the tissue factor pathway in initiating clotting in vivo; 2, the interactions between pathways; and 3, the pivotal role of thrombin in sustaining the cascade by feedback activation of coagulation factors. HMWK = high-molecular-weight kininogen; PK = prekallikrein; PL = phospholipid; PT = prothrombin; TF = tissue factor; Th = thrombin. From Schafer, 1994.

cas·cade

(kas-kād'), 1. A series of sequential interactions, as of a physiologic process, which after being initiated continues to the final one; each interaction is activated by the preceding one, sometimes with cumulative effect. 2. To spill over, especially rapidly. [Fr., fr. It. cascare, to fall]

cascade

(kăs-kād′)n.a. A succession of stages, processes, operations, or units.b. Electronics A series of components or networks, the output of each of which serves as the input for the next.c. A chemical or physiological process that occurs in successive stages, each of which is dependent on the preceding one, and often producing a cumulative effect: an enzymatic cascade.
Cardiac Arrest in Seattle: Conventional vs. Amiodarone Drug Evaluation. A trial comparing conventional therapy vs. amiodarone, an antiarrhythmic on M&M in survivors of refractory out-of-hospital ventricular arrhythmias
Conclusion Slight increase in survival free of cardiac death; resuscitated ventricular fibrillation or defibrillator shock was better with amiodarone at 2, 4, and 6 years of followup; overall mortality is high, side effects are common

cascade

Physiology A molecular system capable of self-propagation or amplification, especially of a weak signal; once a cascade is initiated, it may continue to be amplified through positive feedback loops and pathways, until down-regulated by local mechanisms–eg, by proteolytic enzymes. See Complement cascade, Ischemic cascade, Metastatic cascade.

CASCADE

Cardiology A clinical trial–Cardiac Arrest in Seattle: Conventional vs Amiodarone Drug Evaluation–that compared conventional therapy vs amiodarone, an antiarrhythmic on M&M in survivors of refractory out-of-hospital ventricular arrhythmias. See Amiodarone, Ventricular arrhythmia. Cf BASIS.

cas·cade

(kas-kād') 1. A series of sequential interactions, as of a physiologic process, which after being initiated continues to the final one; each interaction is activated by the preceding one, sometimes with cumulative effect. 2. To spill over, especially rapidly. [Fr., fr. It. cascare, to fall]

cascade

A physiological system in which the completion of one event has an outcome that initiates the next successive event. Blood coagulation, for instance, is a cascade involving more than a dozen successive events. In genetics a cascade system controls the order in which genes are expressed.

cascade

sequential ENZYME reactions in which one activated enzyme activates the next in the sequence, which in turn amplifies the initial response, as in the COMPLEMENT system and BLOOD CLOTTING.
