Energy use increases with bpm, change in pressure (systolic - diastolic) and the stroke volume (amount of blood pumped per beat).

Note that there is also an inverse relationship between stroke volume and bpm because the faster the heart beats, the less time for blood to return to the heart for the next beat.

That said, heart "strength" is more about reserve capacity (ie ability to ramp up when necessary) than energy efficiency. It's like comparing a Ferrari to a Corolla: at 100 mph the former can still increase its power whereas the latter is getting near its limit.

So if the Ferrari has a "car attack" and suddenly loses 50% of its max speed then it can still keep up on the highway, the Corolla maybe not. That's more important than which one is more energy efficient.

The doctor prescribed a different medication for her. And doctors, not patients, ultimately get to decide which drug they prescribe.

I don't think her case is going anywhere. She is suing pro se, which means she couldn't find or doesn't want a lawyer to take her case.

Because the doctor prescribed a different drug.

Don't get your hopes up. She sued pro se, which means she couldn't find or doesn't want a lawyer to take her case. Either way, it is very unlikely she will win.

Well, if the second photon is in a new, weird superposition then the first photon must also be in the same new, weird superposition. Again, I don't that's compatible with Copenhagen given that the first photon no longer exists.

Note by the way that 50% y+ and 50% y- is how all photons start. So if that's also the final state then there is no reason for it to prefer any detector over the others.

Doctors are expected to mitigate risks, too. Valproate-induced spina bifida is a real problem, and doctors share a responsibility to prevent it when it won't harm their patients. They share this responsibility because they previously tried making patients entirely responsible for mitigating their risk, and that approach has failed.

Nobody said the woman in the article "has to suffer". They didn't refuse to give her any medicine, they refused to give her a particular medicine. There are plenty of alternatives, and in fact the doctor in this article wrote the woman a prescription for a different medicine. But of course, some people only want what they can't have.

Despite what patients often think, doctors are not drug dispensaries. It's not their job - and never has been - to give patients the latest drug they read about online, or the drug that worked for their friend, or the drug that someone said "ask your doctor" about. If there is a less risky drug that can treat the patient, they will prescribe that instead of what the patient wants.

To take another example, vancomycin is an antibiotic of last resort. Bacteria have not yet developed widespread resistance to it, so it is reserved for patients who have antibiotic-resistant infections, like MRSA. If it is used too much, theoretically bacteria can finally develop resistance to it. And theoretically, people in the future with MRSA may suffer.

Next time you get antibiotics, try telling your doctor "No, I want a vancomycin prescription". You will be disappointed. They are going to give you what they think will get the job done without incurring unnecessary risks, for you or other people.

Entangled electrons are entangled in all directions. If you measure one along any direction, you can completely predict the measurement of its pair in the same direction.

In other words, measuring one along X and its pair at Y is equivalent to measuring one along X and then measuring the same one again at Y (accounting for the sign shift in the pair, of course).

In the electron example, if the two electrons are entangled then the wave functions must be the shared. The new superposition for the second electron would therefore be shared with the first electron. So if you measured the second electron along z+ and got up, then if you measured the first electron again, this time along z+, it would give down.

Likewise if the twin photon is still in superposition, then the first photon is also in superposition. Which is hard to accept in the Copenhagen interpretation, given that the first photon has been absorbed. If absorption doesn't completely collapse a wave function, then what does?

My guess is that the drug is valproate. It's used for headaches as well as epilepsy, though obviously other drugs can be used instead.

The problem with valproate is that it is causes birth defects in two thirds (!!) of pregnancies, including spina bifida in 10% of pregnancies.

The World Health Organization and the European Medicine Agency have issued statements/regulations against prescribing it to any women of childbearing potential. Plenty of American docs take a similar approach, regardless of religious beliefs. Just to be crystal clear, neither the WHO nor the EMA pay attention to Dobbs, the SCOTUS, or the GOP.

If you go to a doctor and demand a course of antibiotics for a viral infection, they have been trained to refuse. Because antibiotics do not treat viruses.

For that matter, if you actually do have a simple bacterial infection and immediately demand a last-resort antibiotic like vancomycin, doctors have been trained to refuse. Vancomycin may work on you, but using it may create bacterial resistant strains that will put others at risk. Resistance is especially a threat if you don't complete your course of antibiotics.

So doctors will offer you a different antibiotic instead, with less risk of creating a resistant strain. Even if you promise to complete your antibiotics, "you get what you get so don't get upset".

People have agency, but so do doctors. Doctors are not supposed to be dispensaries who simply give patients whatever they ask for. Doctors have the right to refuse to provide a prescription that is not in keeping with the standard of care, and offer a different prescription instead. You have the right to find a different doctor, or not see a doctor at all.

I'm quoting the World Health Organization and a European agency, neither are American health care.

This is a universal approach taken by health care in the US, EU, and across the world. Doctors in general are pragmatists, and only concerned with outcomes. Which means acknowledging that no matter how often patients say "Trust me", they know a certain number will have a bad outcome. The doctor's job is to reduce that number.

It's the same reason why doctors increasingly urge their patients to not keep firearms at home. Even when the patient says they can be trusted with a firearm. It's not a matter of trust, it's a matter of statistics.

Most people who take Viagra have hypertension, because hypertension is the main cause of ED. That doesn't mean Viagra is dangerous, but you shouldn't combine it with certain other drugs.

There is a world of difference between valproate and Viagra. Valproate causes birth defects and cognitive delay in 30-50% of pregnancies, which is astonishingly high. If Viagra caused permanent harm to even 5% of users, it would already be off the market.
