In my reading of the scientific and medical literature, I have come across the term “retrosternal oppression”.

To be clear, I don't demand that I use enumerate. I just want to reproduce the image. I tried variations of flalign and multicols but couldn't get it to work.

I want to know how to precisely configure the vertical alignment of equations in tabular, for example, \arraystretch can increase the height but cannot make equations vertically centered, their baseline is too low. Also, inline equations and display-style equations can be both well aligned. \docu...

Thanks for checking out my question. Like the title said, is the phrase “In the morning on Friday” correct? And if it is correct to say “In the XXX on XXX”, then when EXACTLY should we use “in” and “on” for sections of a day? If no, why? I know that you have to use “on” when saying like “On the m...

i am new to adobe illustrator and tried to fit an triangle to a square. The problem is that that is not fitting perfectly. Either the corner are outside or the line is not ending with the square. Is there a way to match them perfectly.

Many home computers in the 1970s and 1980s had two floppy disk drives, or owners bought a second drive, to reduce having to play disk jockey. A second drive was especially popular with Commodore Amiga owners, as many games around 1990s came with several disks (and hard drives were uncommon for th...

Is it possible to prevent users to bypass a certificate warning showed in their browser, and if so, how? Assuming we have no control on the remote server, and total control on the client computer. The question relates to the Chrome web browser.

While studying abstract algebra I encountered the following question: Given an abelian group $G$ and its two sub-groups $H_1, H_2$, such that $H_1 \cap H_2=\{e\}$, prove that the group generated by $\langle H_1 \cup H_2 \rangle$ is isomorphic with the group $H_1 \times H_2$ (their Cartesian prod...

According to PHB p.82 the Oath itself is a source of power for paladins (emphasis mine).

I am using an ESP32 WROOM 32D on a self-designed PCB to read from two sensors: an IMU (LSM6DSO32) and a pressure sensor (LPS22df). The IMU reads and writes flawlessly, while the pressure sensor hasn't so far. To see wether the chip works at all, I ran an I2C scanner program, which cycles through ...

A GAN-like architecture for text generation is proposed in 'Generative Adversarial Networks for Text Generation'.

Let's pretend the Fourier transform was never invented. Well, how could we prove there exists a linear transform $L$ over complex numbers such that, for two convolved integrable functions $f*g$, that $L[(f*g)(t)] = k \cdot L(f)L(g)$ for some normalization constant $k$? I don't know much about abs...

I read a book from my dad when I was younger and have been trying to figure out what it was for years. He has no idea what it was.

I get that this might be subjective since 略字 themselves originated (mostly) subjectively, but are there any rules for being able to create/use new ones? For example, the 广+マ representing 魔 or 摩 is quite common. This blog post shows 木 + ｷ to represent 機 (which I've seen), but it also shows 艹+ヤ f...

In "Top Gun: Maverick", the pilots plan to perform a bombing run in the valley of a craterous mountain range in F-18s.

In the following circuit of a transistor I know that \$V_A = 2.5V\$. How do I know in which zone the transistor is operating?

This is a short story from Asimov's Science Fiction Magazine in the 1980s, I think. Merlin finds Arthur's daughter in a modern American city, for purposes I don't remember.

We know that monsters can't swim. A group has survived in a small island. If those monsters came from space (as it seems from the ball of fire falling from heaven in the begining of the movie 2), they may not have arrived in every continent.

To be most effective, a windmill must face into the wind. Some windmills achieve this with a passive yaw system, where the wind automatically adjusts the direction the windmill is facing, often with a tail fin. For my story, space fairing people use mirrors to focus sunlight onto water boilers,...

There are works in science fiction (the Dune saga probably being the most famous of them) where in the future, a space-faring human society has somehow, instead of being a republic (at least in name, if not in fact) or turning into megacorporate entities, has reverted to feudalism with clear-cut ...

Suppose $\langle L,\leq\rangle$ is a lattice with join $\sqcup$. Let $F_1$ and $F_2$ be principal filters on $L$. Thus, for $i\in I=\{1,2\}$ there are $x_i\in L$ so that $F_i=\{y\in L:x_i\leq y\}$. In this situation, $F_1\cap F_2$ is also a principal filter, because $F_1\cap F_2=\{y\in L:x_1\sqcu...

In Star Trek: First Contact (1996), during the battle with Starfleet which takes place very near to Earth, a Borg Sphere comes out of the damaged Borg Cube and then it uses time travel to go back in time to the year 2063 AD.

According to the Bible, all demons are believers: You believe that God is one; you do well. Even the demons believe—and shudder! (James 2:19 ESV) Yet, this is not the case for (all) humans. Some humans are atheists. Why? Why are there no atheist demons? Why are there atheist humans? Are there f...

Longer wavelengths require cooler temperatures to detect efficiency. The MIRI detects all the way out to 25um and so needs to be cooled to 7K.

In Quantum Field Theory, the calculation of scattering amplitudes relies on interaction terms like $\lambda \phi^4$ or $\psi ' \gamma ^{\mu} \psi$. These are products of field operators calculated at a spacetime point. Derivation of most interaction terms employs local gauge symmetries, which is ...
