Why do unshielded twisted pair cables need a different pitch/twist rate for every pair of wires in a cable? Most of my reading on UTP says that the pairs in a cable must have different pitch or else the benefits of UTP will be lost which is the noise cancelling. From what I understood, twisting t...

When a Windows .exe installer is code-signed, I thought that modifying a single byte (thus changing its SHA256 hash) would make the digital signature invalid, but surprisingly, this is not true.

I'm stunned by the chapter in my coursebook (which is in Dutch, so please advice if I am mistranslating any of the terms) about deriving from a system of axioms and derivation rules. The exercise is to prove the following: $$p \vdash_S q \rightarrow p$$ Step one is to assume p. That makes sense t...

Let $(\Omega,\Sigma,\mu)$ be a probability space, $E$ be a separable Banach space, $f:\Omega\rightarrow E$ be Borel-measurable and consider the Bochner-integral $$ \bar{\mu}:=\int_{\omega\in \Omega}\, f(\omega)\, \mu(d\omega). $$ If there is a convex set $C\subseteq E$, such that $f(\Omega)$ is a...

I was reading the proof of Ossowski theorem about bipartite graphs without $(r+1-a)\times a$ cliques for $a=1,\dots,r$.

Quoting Wikipedia: No algorithm has been published that can factor all integers in polynomial time, that is, that can factor a $b$-bit number $n$ in time $O(b^k)$ for some constant $k$. Neither the existence nor non-existence of such algorithms has been proved, but it is generally suspected that...

For any real number $r$, the convergents to the continued fraction expansion of $r$ satisfy Dirichlet's approximation inequality of $|r - \frac{p}{q}| < \frac{1}{q^2}$. Does this go the other way? That is, if given some rational number $p/q$, we have that $|r - \frac{p}{q}| < \frac{1}{q^2}$, does...

In sampling, we have so many situations involving a sequence of random variables, what I am confusing is why do we need a sequence of random variables to describe the process?

In MacLane's Categories for the working mathematician, the author shows that the evaluation at 1 gives an equivalence of categories $\mathrm{hom}_{\mathrm{BMC}}(B,M)\simeq M_0$ where $B$ is the braid category, $M$ is a braided monoidal category and $M_0$ is the underlying (ordinary) category to $...

I've made a hardlink of my source file. But when I edit the source file and ⌘s it, the inode number of it changed and the hardlink was broken. How to protect my hardlinks from being broken?

I have the indices of a cell in an Excel workbook: Worksheet, column, row (and yes, I know that Excel likes 1-based indices.) Given those, what formua should I write to obtain the value of that cell?

May I know what does '4eCe' & '2eCe' mean in this context? *I got this sheet music from imslp.

I see the Descarta2D package to easily draw some figures. Unfortunately, the package is not to be found and runs on MMA 2021? I do want some complex contour calculations and need some diagrams

How am I supposed to add a feature of a given length and/or at a given distance from another point? In QGIS 3.4 I've used the Measure tool to mark the length then switched to "Add Feature". But in 3.22 switching to another tool removes Measure trace and I don't see a setting to switch back to the...

We study the definition of Lebesgue measurable set to be the following: Let $A\subset \mathbb R$ be called Lebesgue measurable if $\exists$ a Borel set $B\subset A$ such that $|A-B|=0$,where $|.|$ denotes the Lebesgue outer measure of a set. Then we have theorems like: $A\subset \mathbb R$ is Leb...

Sci-fi short story (or maybe opening chapter of a novel?) which was read in the late '90s, but could have been written long before that. The plot involved a ship crewed by four men, two of whom being typical tough guys in charge, who abuse the other two, including regularly raping them. The prota...

I am a middle aged woman who went to university where I studied French. This was 30 years ago . If someone asks me: "what have you studied?" can I answer: "I have studied French at university"(without mentioning when), because this is an achievement and/or life experience or is past simple a bett...

I translated my question/text with a translator because English is not my native language. I hope there are no mistakes. Can you to help me to define realistic climate zones and weather of my fictional world map? I struggle with climate zones and weather of my world map. Unfortunately, I don't kn...

I have a 2 year Schengen business visa from Germany. This week i am leaving for the EU on a 3 week trip of meetings in Germany, France, Switzerland and Netherlands. Unfortunately my last week of meetings are still getting planned so I have not yet booked the return flight out of EU since it could...

The question of the asymptotic behavior of $n!$ when $n\to\infty$ usually arises in calculation of time complexity for algorithms and relates to calculation of the following limit. $$\lim_{n\to+\infty}\frac{\ln(n!)}{n\ln(n)}$$ At the first sight, I figured out that it is an $\frac{\infty}{\infty}...

John 3:14-15 "And as Moses lifted up the serpent in the wilderness, so must the Son of Man be lifted up, that whoever believes in him may have eternal life." ESV. My emphasis. Here, looking to the serpent as an external object is contrasted with a different sort of faith. When we are in him, w...

I want to place two different figures side by side, but I want the same caption under the figures and not two different ones. I'm using this code: \begin{figure}[H] \centering \begin{minipage}{.5\textwidth} \centering \includegraphics[width=.6\linewidth]{sinexeia} ...

Is there a way to write Hebrew letters in a text object? I can't write Hebrew directly. I also tried to copy and paste letters with "Ctrl + v" but to no avail. Is there any way to do that?

Can you concatenate the numbers from 1 to 20 in some order, such that the resulting 31-digit number is a palindrome?

Let $A = \left( {\begin{array}{*{20}{c}} 0&1&1\\ 1&0&1\\ 1&1&0 \end{array}} \right)$. I want to find $A^k,$ where $k \in N$. So far I calculated $A^2, A^3, A^4,...$ but I can not see the general formula for $A^k$. Here are $A^2, A^3, A^4, A^5$. Not sure if this leads to anything but I found the ...

Let $n\in\Bbb N$ be arbitrary, and define the matrix $A=(a_{ij})_{i,j=0}^n$ via: $$a_{ij}=\begin{cases}0&|i-j|\neq1\\\frac{i}{n}&j=i-1\\\frac{n-i}{n}&j=i+1\end{cases}$$ Which represents the transition matrix of the Markov shift system where $n$ balls numbered $1\to n$ are distributed across two u...
