The radio receiver connected to the receiving antenna detects this oscillating current and amplifies it. This produces a catalytic cascade that amplifies the initial signal by controlled positive feedback. Then it feeds the electromagnetic actuator, which amplifies the signal. Wnt activity thereby amplifies mechanical signalling that occurs during development. SP amplifies or excites most cellular processes. This amplifies the effect of activating glycogen phosphorylase. Emotional reasoning amplifies the effects of other cognitive distortions. "Asymmetric PCR" preferentially amplifies one strand of the target DNA. The ring amplifies the aggressive tendencies of the wearer. This promotes a chain of sustainable businesses that amplifies its effectiveness. After detection, a single-transistor stage amplifies the audio frequency. Glucose immediately amplifies glucokinase activity by the cooperativity effect. An omnidirectional microphone amplifies sounds equally from all directions. This therefore amplifies the cariogenic effect of S.mutans. The medium amplifies the light by stimulated emission.
