Bad news fellow vaxxies, the "turbo cancer" rumor that the conspiracy theorists have been yammering about has turned out to be completely true, as proved by this recent publication:
https://pubmed.ncbi.nlm.nih.gov/38234925/
>The "hallmarks of cancer" were proposed by Hanahan and Weinberg (2000) as a group of biological competencies that human cells attain as they progress from normalcy to neoplastic transformation. These competencies include self-sufficiency in proliferative signaling, insensitivity to growth-suppressive signals and immune surveillance, the ability to evade cell death, enabling replicative immortality, reprogramming energy metabolism, inducing angiogenesis, and activating tissue invasion and metastasis. Underlying these competencies are genome instability, which expedites their acquisition, and inflammation, which fosters their function(s). Additionally, cancer exhibits another dimension of complexity: a heterogeneous repertoire of infiltrating and resident host cells, secreted factors, and extracellular matrix, known as the tumor microenvironment, that through a dynamic and reciprocal relationship with cancer cells supports immortality, local invasion, and metastatic dissemination.

>>
>>16150025
>>16149865
alright so here's the mistake, on the third line, the person who made this chart substitued "any severe adverse event" for what is actually in the original paper "any severe event". As I said before, adverse event and any events aren't the same thing. You can argue that they're not properly reporting some events as adverse events and maybe you're right, maybe you're wrong, the fact is that this chart changed what the paper is saying and that I personally have no way to check how they reported these events.
So we're left with a 10% increase in serious adverse events, and 300% increase in any adverse events. I'm not surprised personally, actually I'm surprised it's not more than that for the serious adverse events, everyone knows that it can induce myocarditis among other things, and I don't expect a placebo injection to be so close to those of a vaccine injection.

for the second part about the death count, I tried to figure it out but it doesn't go into details, but as it shows in your own chart, there is no number for placebo, not even 0. Because it's nowhere mentionned how many people kept without a vaccine shot after the study period. If 90% of the people eventually got the shot, which isn't far fetched since it became mandatory for a large part of the world, it means you're practically left with only people who have received the vaccine. No wonder some of them continue to die. You're not comparing similar groups anymore.

I don't know why you also keep repeating there's more people in the control group but it's false.

Now about canadian covid care alliance :
>Toronto, Ontario physician and cofounder of Canadian Covid Care Alliance, Ira Bernstein, launched Canadian Covid Telehealth, at the address of his Toronto practice, as a "covert prescription network" where he and his colleagues could prescribe ivermectin. In a November video announcing the creation of Canadian Covid Telehealth, Bernstein admitted that Health Canada has not approved the drug. He said, without evidence, that Health Canada and the regulators were not basing their claims against the use of ivermictin on "any credible science."

>Ira Bernstein, 49, was charged with multiple felonies last week for attempting to solicit the murder of his wife, Susan Bernstein, between July 29 and Sept. 21, 2022, the Rockland County District Attorney’s Office announced.

What makes schizophrenic people draw shit like this? All I got from looking it up was it’s a chemical imbalance in the brain that messes up your dopamine receptors but how does that translate to the weirdly specific recurring symptoms like drawing shapes and thinking the government is hunting you down because you’re the new Jesus? Have they done much research into this?

>l I got from looking it up was it’s a chemical imbalance in the brain that messes up your dopamine receptors but how does that translate to the weirdly specific recurring symptoms
It doesn't because schizophrenia isn't a chemical imbalance issue. That's a myth propagated by the pharmaceutical companies because they had to find an explanation as to why all these people got put on what originally amounted to sedatives and tranquilizers, e.g. first-generation antipsychotics. That stuff made you drool out of your mouth.
>Have they done much research into this?
No, they haven't. Why would they. You believe that it goes from A to B where it is the schizophrenia (A) that causes people to draw weird stuff (B). In fact, however, the diagnostic procedure goes from B to A. In other words, for you to have schizophrenia, you must have been drawing weird stuff in the first place.

Use the fact [eqn]\sum_{k=1}^{n} k^a = \frac{1}{a+1}n^{a+1} + \frac{1}{2}n^a + ...[/eqn]

You can use the fundamental theorem of Calculus to evaluate
[eqn] \frac{1}{n^{2025}} \sum_{k=1}^n k^{2024} = \int_0^1 x^{2024} dx = \left. \frac{x^{2025}}{2025} \right|_{x=0}^1 = \frac{1}{2025}[/eqn]

>>16150093
tangent is sine over cosine, so it goes to +/- inf whenever cos = 0
0 isn't an inflection point of cos, so its sign will always change upon passing through 0. Since sin's sign doesn't change at that same point (because of the phase difference), the result is that tan will always flip sign as it passes "through infinity"

There exists [math]i \in \mathbb{N}[/math] so
>[math]a_n - 10^{-m} \leq b_i \leq \sup \{b_i | i \in \mathbb{N} \}[/math]
Yes.

>As the function [math]f[/math] is [math]\mathbb{D}[/math]-continuous it is true that for any [math]m[/math] there exists [math]k[/math] such that if the inputs are k-close, the outputs are m-close.
First, it's not correct to use k-close as a synonym for "corresponding numbers are less than [math]10^{-k}[/math] apart." They are non-equivalent statements, and "k-close" is the more complicated, uglier one which we should avoid using where possible. Second, even with that substitution (which I would not expect to affect the truth of the statement), the statement is not true. In particular, it is false for finite decimal multiplication. We need to use the whole definition and not skip parts of it, or we don't have a proof.

>Isn't that last statement by definition?
No, in [math]\sup_j \inf_{i \leq -j} f([{\bf x}]_i)[/math], the [math]j[/math] runs over all integers. So we have to show this doesn't change the result.

>>16149946
I don't see what's missing?
>>
>>16150069
You're missing the "with all [math]|x_i|, |y_i| < N[/math]" part.
>>
>>16150073
So if we replace the k-close statements with the corresponding [math]< 10^{-k}[/math] statements and also require that [math]|x_i| < N[/math] then my proof works?
>>
>>16149946
>No, in [math]\sup_j \inf_{i \leq -j} f([{\bf x}]_i)[/math], the [math]j[/math] runs over all integers. So we have to show this doesn't change the result.
So we have to show it's the same whether it is all integers or all natural numbers?
