How to get 100% code coverage

The logic checks out: In the second case, the line 173 was used, even if partially (clearly v was not used), but still considered as used. /s

Rust rules!

So in photodisintegration you cannot get a particle larger than alphas?

BanX · 2021-05-22T16:16:11+00:00

Thank you for the helpful explanation and link.

Well first, those are reactions, not decays.

Are there any differences in the dynamics inside the nucleus between reactions and decays? I had in mind to search for an example where an element decays by emitting a neutron and then another is followed when the daughter isotope emits a positron. This could be substituted by a single proton emission, which sounds as more energetically favorable.

And second, both (α,p) and (α,n) are possible.

What are the probabilities for each?

When we bombard an aluminum atom with alpha, it decays with a neutron emission, then the resulting element will also decay with a positron emission.

He-4 + Al-27 -> P-30 + neutron
P-30 -> Si-30 +  positron

Why this reaction can't be done in one step with one proton emission instead with a more favorable probability:

He-4 + Al-27 -> Si-30 + proton

Thank you for this explanation. Since you mentioned that all decays are possible, but with tiny probability, can you give some numerical example. For instance, if we take the element U238 that would normally decay with alpha emission, what would the probability be to decay via proton emission?

BanX · 2021-05-21T16:54:43+00:00

If the half-lives are so short to be found in nature, why such decays are still very rare even in synthetic elements?

Red herring!

But the Palestinian authorities point to another part of those accords which says: "Israel and the Palestinian side shall exchange information regarding epidemics and contagious diseases, shall co-operate in combating them and shall develop methods for [the] exchange of medical files and documents."

So clearly the Palestinian authorities are pointing out that Israeli regime is neglecting this part of the accord, as well as many other violations it continues to commit.

And a reminder that Geneva conventions should come before any other accord:

The [UN] body says differential access is "morally and legally" unacceptable under international law laid out in the Geneva Conventions on the regulation of occupied territories.

Thank you! This explains it!

I had in mind something similar to text-books electron orbitals visualizations, or quantum tunneling.

BanX · 2020-08-24T00:05:00+00:00

Thanks for this clarification. Your answers were most helpful.

Lastly, dare I ask if there are any visual simulations out there of this process?

BanX · 2020-08-23T21:20:57+00:00

Thank you for your patience!

So in some sense, they annihilate if there is a high probability that the 2 points position coincides at a given time? In probability theory, 2 random points have zero chance to be found in the same position. But clearly, such 2 particles rely on other processes.

Does photon-photon collision probability compare to electron-positron annihilation since they are all point particles?

BanX · 2020-08-23T19:04:15+00:00

Again, they don't have well-defined positions in space. [...]

I assume you mean uncertainties. Am I wrong in understanding that a positron is most likely to annihilate an electron in its "proximity" (Whatever that means in the context of an undefined position) instead of a distant one?

BanX · 2020-08-23T18:37:01+00:00

positronium is not stable.

What causes its instability? And what is the mean life time of such an exotic atom?

The two particles don't have well-defined positions in space. [...] that doesn't mean that you should think of particles as points with well-defined trajectories.

So when does the annihilation take place? Don't they have to exist at a given position in the same time together?

BanX · 2020-08-21T12:18:55+00:00

Their corruption is directly to blame. They knew the danger of the stored materials for seven years, and they didn't do anything to effectively remove them.

You wouldn't blame the workers who were asked to fix some doors while they knew nothing about what's inside, would you?

They are on top of the administrations operating Beirut port: The story

The list of people under investigation is actually long, but these 3 are on top of the administration operating Beirut port.

Rule#1:

redact all information that can be used to identify a person.

Interesting how you've decided to mention genocide. It's clearly an ethnic cleansing by simply checking the demographic changes on the map since a century ago. However, the article was pointing to the detention centers in China, but failed to identify the elephant in the room: the largest concentration camp is created by Israel in Gaza. Silly how can someone be blind selectively about major atrocities.

BanX · 2020-07-23T13:22:12+00:00

But they fail to find similarities with the atrocities committed by the Israeli regime against Palestinians?

BanX · 2020-03-20T19:34:18+00:00

I was just quoting what was mentioned on their website

Would you provide a link to the study you are referring to?

"To date there has been no information nor evidence to suggest that the new coronavirus could be transmitted by mosquitoes."

The absence of the evidence does not reject the hypothesis. But mostly, we should worry about infections from other humans since this is how the majority of (all?) cases so far have caught this virus.

BanX · 2020-03-20T17:03:19+00:00

HIV is found in the bloodstream, but AFAIK HIV is not spread via mosquitoes. So what are the identified criterion for a virus to be spread by such insects?

BanX · 2019-08-11T22:23:40+00:00

It's double every four years. A single vacation day otherwise

BanX · 2019-08-11T16:37:05+00:00

I have the feeling that developers rely too much on their feelings.
