I understand that each certificate can have a CRL distribution point (extension 2.5.29.31) – or even multiple ones, but let's not consider that for the moment. Let's assume we have a root CA > intermediate CAs > and leaf certificates. My understanding is that the root CA issues (signs) any interm...

It appears that isotonic regression is a popular method to calibrate models. I understand that isotonic guarantees a monotonically increasing or decreasing fit. However, if you can get a smoother fit, which also respects this property via other regressions, why keep isotonic regression instead of...

Motivation. The Kakutani fixed point theorem states: For $S \subset \mathbb{R}^n$, non-empty, compact and convex, and $\varphi : S \to 2^S$, if $\varphi$ has a closed graph and, for all $s \in S$, $\varphi(s)$ is nonempty and convex, then there exists an $x \in S$ such that $x \in \varphi(x)$. ...

My mom and I were out for a walk today. On the way back home, I remembered to pick up a bag which I had left for a repair a few days ago, but the weather was very cold, so I didn't want to make my mom walk all the way to the repair shop in cold weather. So, to tell about this situation, I said: ...

Scenario: A woman is a high-ranking member of the embassy to Canada from a country outside North America, and she enjoys full diplomatic immunity in Canada. She goes into labor and has serious complications away from a hospital. Considering the weather, the best course of action is to fly her in ...

I need to do a lot of calculations on numpy arrays, with some of the calculations being repeated. I had the idea of caching the results, but observe that In most cases, the cached version is slower than just carrying out all calculations. Not only is the cached version slower, line profiling als...

In Ginzberg's Legends of the Jews, he refers to the well-known midrash that the Hebrew slave Moses saved from a beating was Datan, and that the fight the following day was between Datan and Aviram. But he adds a curious extra detail about the fight: The two brothers began of malice aforethought ...

SMD coded VCH component I have an LG home theater LHB625, and the Bluetooth is not working. I removed the Bluetooth module, and the VCH-labeled component in the picture overheats. I suspect it is faulty, but I couldn’t identify what this IC is.

Now that I think of it, I've never seen or heard someone use "one'd" (One would, one did, one had), "one'll" (one will/shall), or "one's" (with the meaning "one is/has," not the possessive of "one.") I also cannot find any examples on google search. Are these ever used at all, whether currently o...

I am watching a presentation on Dynamical Logical Qubits in the Bacon-Shor Code. In the presentation, the presenter introduces the three-qubit code as an example, where he defines: Logical Qubits as: $$ |0\rangle_L = |000\rangle \quad \text{and} \quad |1\rangle_L = |111\rangle $$ Logical Operat...

I'm trying to rigorously understand Dirac notation in continuous variable quantum mechanics. I'm told the most common approach is via rigged Hilbert spaces. This means we have: $$\Phi \subset H \cong H^* \subset \Phi^* \text{ and } \Phi \subset H \cong H^\times \subset \Phi^\times$$ where: $H$ i...

I've noticed a camera technique used in some films where the focus shifts from one subject to another within the same shot, blurring the background or foreground and then bringing a new element into sharp focus. I believe this is called a "rack focus" or "focus pull." I'm curious to understand th...

Fuhrmann and Uwe Helmke Background $\textbf{Theorem 2.59 (Local-Global Principle).}$ Let $M$ be an $R-$module. $1.$ Then $M = \{0\}$ if and only if $M_m = 0$ for all maximal ideals $m$ of $R.$ $2.$ An element...

I made this puzzle myself, similar to the Tutui Test.

I'm considering upgrading 650c wheels on a Gunnar Roadie to carbon fiber. Would 650b wheels work? That would open up a lot of tire options.

I am currently a postdoc in applied mathematics and am getting ready for applying for tenure-track jobs. My preference is getting a job in an r1 or r2 school. Quantity-wise I have been told that I am in a reasonable range having 12 publications. However, I have 4 papers with MDPI. I know these ar...

Does there exist a structure $(R;+,*,-,0,1)$ which satisfies all the axioms for commutative rings, except for the distributive property, but instead satisfies the FOIL property: $(a+b)*(c+d)=ac+ad+bc+bd$? I would be very interested in an example of such a structure. Note that in such a structure,...

Assuming that nuclear fusion becomes practical, it will be generating heat at a temperature of approximately 100 million degrees C. In order to generate electricity, that heat must be transferred to high pressure steam at a MUCH lower temperature in order to turn the turbine on a turbo-generator...

This mural in Novi Sad is near Radnička and Stražilovska Streets. I would like to know a more precise location, and the woman it represents.

I heard a story about Rabbi Yehoshua Neuwirth, author of Shemiras Shabbos K'hilchasa, who apparently also lived in Amsterdam, that goes as follows (my own rephrasing): During the war, Rabbi Neuwirth spend hiding in an attic with just one sefer (book): Mishnah Berurah, Cheilek 3. He learned it o...

I'm trying to better understand how to select random effects in a binomial GLMM. Currently, I'm using a forward-selection approach with AIC and likelihood ratio tests, but I'm also interested in looking at the random effect variance to inform my choice. I know that if the random effect variance i...

I did a search in Google Scholar and it looks like in contemporary anglophone philosophy there's no problem of human being (problem of man, das Problem des Menschen), no significant studies of philosophical anthropology.

I am having trouble understanding Laplace transforms and initial conditions in the case of a forced harmonic oscillator of general equation of motion $x'' + \omega_{0}^{2} x = \frac{f(t)}{m}$.

I converted my dissertation into a 30-page peer-reviewed journal article (copied and pasted). It was published.

若い人にこの歌詞が歌われてるのが、私は本当に嬉しい (from this twitter post: https://x.com/mikatin_tsl/status/1881119468149231675) I'm not sure if the person means "sung for young people (audience) - 若い人のために歌われてる" or "sung by a young person". Is there a way to disambiguate it?

A partial ordering is any relation that is irreflexive and transitive. For a partial ordering to be "left-narrow", it must satisfy the property that $\forall x,\{ y\vert yRx\}$ is a set. I understand that this definitely implies that $\{ y\vert yRx\}$ is a class, and that this may not necessarily...

I’m currently doing a masters in history and my dissertation is going to be on the era of Catherine the Great. Consequently, a lot of the most important archives are in St. Petwersburg.

You have a Tower of Hanoi-esque set of 3 pegs. There is a stack of unsorted disks labelled from 1 to n (inclusive) on one of these pegs. The other two pegs are empty. The only move allowed is to move the top k disks from a peg A to another peg B, without changing the order of the moved disks. (Th...

This is not about cutting the middle tabs to make a switched outlet. This is about frustration getting wire hooks around and under the screws, and tightening the ends together, and it would be much easier if that middle tab (pictured) was removed (probably blunt force).

I'm working on a programming language that's intended to compile to retro hardware, and I want to add a PRNG to the specification.

I accidentally connected the +5V DC output of this power supply to a 24V DC source for a few seconds. Since then, the +5V DC output reads 0V, but all other outputs (+26V DC, ±12V DC) are functioning correctly. The power supply converts from 18V AC to multiple DC voltages: +26V, +5V, and ±12V. I’v...

For my dialogue tags, I use the word "says" rather than "said" whenever a character speaks and responds, for example: "What do you want for dinner tonight?" Mary says. "As long as it's not meatloaf again, I don't care." John says. Is this grammatically correct or off?

How would this...

Something struck me as odd with the last "Kurz und leicht" video from DW. In English you'd say "Palestinians" but in the video they said "Palästinenserinnen und Palästinenser". This seems cumbersome, and I thought that "Palästinenser" would be enough if it was a group with both genders. The video...
