Newsweek hospital ranking
Newsweek hospital rankings include India, Japan and Mexico also.

Is there any other worldwide ranking in USA and Europe which checks hospitals in developing countries also similar to newsweek. MisteadBean (talk) 09:46, 31 October 2023 (UTC)

Circuit breakers and surge protectors.
Are there any antagonism in electronics? For example in pharmacy, 2 medications can be antagonistic if they're taken together. Meaning, they have to be taken separately. Wonder if there's something like that in electronics. So for example, in a circuit, if the amp is too high, can trigger a circuit breaker which shuts down the circuit. Or, if the voltage is too high, then triggers the surge protector, to shut down the circuit. What if high amp and high voltage at the same time, triggering both at the same time, is there any contraindications in that? 170.76.231.162 (talk) 16:00, 31 October 2023 (UTC).
 * The example you use has no interaction. A circuit breaker will literally break the circuit. Electricity will quickly stop flowing. Any components past the circuit breaker will have no electricity. So, a surge protector will have no electricity to catch a surge. A surge protector usually shorts out surges. Better ones connect power, neutral, and ground together momentarily to send the surge to the neutral line and ground. It is possible that a long-term short can increase current enough to also cause the circuit breaker to trip. But, that would be fine. Both components are doing exactly what they should do. If you really want a very weird circumstance, there is the possibility that a circuit can have a large running electric motor. The circuit breaker trips and electricity suddenly stops flowing. Some electric motors send a power surge when they suddenly shut off, which can cause a surge protector to short out the line to block the temporary surge. So, it is possible that a surge protector can trip a circuit breaker. It is possible that a circuit breaker can cause a power surge that needs to be limited by a surge protector. But, neither of those are considered anatonisitic contraindications. The components continue doing exactly what they are designed to do. 12.116.29.106 (talk) 16:59, 31 October 2023 (UTC)
 * Electromagnetic compatibility covers some of these concepts for electronics. --Amble (talk) 17:15, 31 October 2023 (UTC)
 * I think the example of switching off a motor is the sort of thing the poster is thinking of okay. Yes it follows physical laws, but the medicine is too. You probably don't want the motor to generate a spark or destroy some transistors but it can do it anyway if one wires it up wrong. NadVolum (talk) 19:19, 31 October 2023 (UTC)
 * Halfwave.rectifier.en.svg halfwave rectifier circuit shown to the right has a diode –– allowing current in one direction. You can flip it like –– without impairing the function of the circuit. But if you put two together in series like this: –––––, the circuit stops functioning. --Lambiam 04:09, 1 November 2023 (UTC)

More versatile than just the pharmacological suppression of a medication, a fully balanced electronic mixer can usefully permit, suppress or invert the effect of a signal input. The two inputs to an electronic balanced mixer can be called "antagonistic" because the mixer output is their product by multiplication. Thus a positive swing at one input causes either a positive swing or a negative swing at the output, the actual direction depends on the polarity of the other input.



The binary logic counterpart to the analog balanced mixer is the exclusive-OR gate. It gives a similar "antagonistic" output when fed with square waves at different frequencies except that neither input can suppress the other. Philvoids (talk) 16:06, 2 November 2023 (UTC)
