bullfighting: Act one: ” The rebolera is a finishing flourish to the passes in which the cape is swirled around the bullfighter’s waist like a dancer’s dress. If beautifully executed, a variation of this last maneuver (the serpentina) transfixes the bull in place, at which point the bullfighter can actually…

radiation: Surface effects: Conceptually, the simplest is rebound sputtering, in which an incident ion strikes an atom on the surface, causing it to recoil into the target. The recoiling atom promptly collides with a neighbouring atom in the target, rebounds elastically, and is ejected from the surface. A similar but somewhat more…

international law: Treaties: The concept of rebus sic stantibus (Latin: “things standing thus”) stipulates that, where there has been a fundamental change of circumstances, a party may withdraw from or terminate the treaty in question. An obvious example would be one in which a relevant island has become submerged. A fundamental…

Ian Rankin: …Crosses, introduced the character Inspector John Rebus, a rough-edged former military man serving in Scotland’s territorial police force.

nucleic acid: General recombination: A key enzyme is RecA, which catalyzes the strand invasion process. RecA coats single-stranded DNA and facilitates its pairing with a double-stranded DNA molecule containing the same sequence, which produces a loop structure.

logistics: Returned products: …few are subjects of product recalls, meaning that a safety defect or hazard has been discovered. These products are removed from the shelves, and both retailers and consumers attempt to return them to the manufacturer. This is a form of reverse distribution, with goods moving in the opposite direction of…

F-score: Recall is the fraction of a dataset’s actual “yes” values that a model includes in its classified group of “yes” values. This score is considered to be helpful in determining how well an algorithm classifies a dataset into two categories and is widely used in…

recall, in psychology, the act of retrieving information or events from the past while lacking a specific cue to help in retrieving the information. A person employs recall, for example, when reminiscing about a vacation or reciting a poem after hearing its title. Most students would rather take a

Spain: The Visigothic kingdom: …adhered to the Catholic faith, Reccared (586–601) repudiated his father’s religion and announced his conversion to Catholicism. As the Gothic nobles and bishops followed his lead, a principal obstacle to the assimilation of Visigoths and Hispano-Romans was lifted. Thereafter, the Hispano-Romans, no longer expecting deliverance by Byzantium, developed a firm…

nucleic acid: General recombination: Another protein, known as RecBC, is important for the recombination process. Functioning at free ends of DNA, RecBC catalyzes an unwinding-rewinding reaction as it traverses the length of the molecule. Since unwinding is faster than rewinding, a loop is produced behind the enzyme that facilitates subsequent pairing with another…

textual criticism: From antiquity to the Renaissance: , readable), texts were corrected freely and often arbitrarily by scholars, copyists, and readers (the three categories being in fact hardly distinguishable). At its best, as seen in the activities of a scholar like Demetrius Triclinius, later medieval and early Renaissance criticism verges on scientific scholarship, but…

receptive field, region in the sensory periphery within which stimuli can influence the electrical activity of sensory cells. The receptive field encompasses the sensory receptors that feed into sensory neurons and thus includes specific receptors on a neuron as well as collectives of receptors

drug: Receptors: Receptors are protein molecules that recognize and respond to the body’s own (endogenous) chemical messengers, such as hormones or neurotransmitters. Drug molecules may combine with receptors to initiate a series of physiological and biochemical changes. Receptor-mediated drug effects involve two distinct processes:

receptor, molecule, generally a protein, that receives signals for a cell. Small molecules, such as hormones outside the cell or second messengers inside the cell, bind tightly and specifically to their receptors. Binding is a critical element in effecting a cellular response to a signal and is

information processing: Basic concepts: The two other components, the receptor and the effector, are input and output mechanisms whose functions are, respectively, to receive symbolic expressions or stimuli from the external environment for manipulation by the processor and to emit the processed structures back to the environment.

chemoreception: Signal transduction: The initial changes are called receptor potentials, and they are produced by the movement of positively charged ions (e.g., sodium ions) into the cell through openings in the cell membrane called ion channels. Thus, in order to stimulate a receptor cell, a chemical must cause particular ion channels to be…

drug: Receptors: …effects involve two distinct processes: binding, which is the formation of the drug-receptor complex, and receptor activation, which moderates the effect. The term affinity describes the tendency of a drug to bind to a receptor; efficacy (sometimes called intrinsic activity) describes the ability of the drug-receptor complex to produce a…

drug: Receptors: …the cellular response (also called receptor-effector coupling). Among the most important ones are the following: (1) direct control of ion channels in the cell membrane, (2) regulation of cellular activity by way of intracellular chemical signals, such as cyclic adenosine 3′,5′-monophosphate (cAMP), inositol phosphates, or calcium ions, and (3) regulation…

cosmology: Finite or infinite?: His discovery of the systematic recession of the galaxies provided an escape, however. At first people thought that the redshift effect alone would suffice to explain why the sky is dark at night—namely, that the light from the stars in distant galaxies would be redshifted to long wavelengths beyond the…

political economy: National and comparative political economy: …however, many Western countries experienced “stagflation,” or simultaneous high unemployment and inflation, a phenomenon that contradicted Keynes’s view. The result was a revival of classical liberalism, also known as “neoliberalism,” which became the cornerstone of economic policy in the United States under President Ronald Reagan (1981–89) and in the United…

animal social behaviour: The ultimate causes of social behaviour: Reciprocal altruism or reciprocity is one solution to the evolutionary paradox of one individual making sacrifices for another unrelated individual. If individuals interact repeatedly, altruism can be favoured as long as the altruist receives a reciprocal benefit that is greater than its initial cost. Reciprocal…

airplane: Thrust controls: The power delivered by reciprocating and jet engines is variously affected by airspeed and ambient air density (temperature, humidity, and pressure), which must be taken into consideration when establishing power settings. In a turboprop engine, power is typically set by first adjusting the propeller speed with a propeller lever…

Because women were unique in value, reciprocity…

electromagnetic radiation: Continuous spectra of electromagnetic radiation: This observation illustrates the rule of reciprocity: a body radiates strongly at those frequencies that it is able to absorb, because for both processes it needs the tiny antennas of that range of frequencies. Glass is transparent in the visible range of light because it lacks possible electronic absorption…
