For example, the pulse repetition rate and duration may be digitally controlled but the pulse amplitude and rise and fall times may be determined by analog circuitry in the output stage of the pulse generator. With correct adjustment, pulse generators can also produce a 50% duty cycle square wave. Pulse generators are generally single-channel ...

The ratios predicted (by mass, not by abundance) are about 0.25 for 4 He:H, about 10 −3 for 2 H:H, about 10 −4 for 3 He:H, and about 10 −9 for 7 Li:H. [34] The measured abundances all agree at least roughly with those predicted from a single value of the baryon-to-photon ratio.
Microsoft later restricted the total number of chat turns to 5 per session and 50 per day per user (a turn is "a conversation exchange which contains both a user question and a reply from Bing"), and reduced the model's ability to express emotions. This aimed to prevent such incidents.
Every human activity, transport and industrial process generates waste heat, being possible to harvest residual energy from cars, aircraft, ships, industries and the human body. [1] From cars the main source of energy is the exhaust gas. [32] Harvesting that heat energy using a thermoelectric generator can increase the fuel efficiency of the car.
Most infections show no symptoms, in which case it is known as latent tuberculosis. [1] Around 10% of latent infections progress to active disease which, if left untreated, kill about half of those affected. [1] Typical symptoms of active TB are chronic cough with blood-containing mucus, fever, night sweats, and weight loss. [1]
