I have a well-phenotyped survival dataset (i.e. it has a high number of relevant covariates for a study of mortality) for which I estimate how certain conditions influence life expectancy (LE). It would be much more informative to compute this in lost or gained years of life rather than stating a...

I'm sure I'm just tripping up on terminology here. I'm new to the wonderful field of QEC, and so far am familiar with the stabiliser formalism and basic codes such as the generic surface code. I keep seeing references in the [vast] literature to subsystem codes - what exactly is this referring to...

I have found two different definitions of the limit of a function f at a point a in very popular calculus/analysis texts. In one, the function f is asked to be defined on an open interval containing the point a, possibly excluding said point (Stewart, Wade). The other definition, more popular in ...

Recently, I was in a 4-player level 12 free-for-all, and one of the other characters transformed into an earth elemental and burrowed underground, meaning I couldn't see them. This is an afterthought, as I was playing a wizard rather than a cleric, but I was wondering if guiding bolt would work i...

Looking to build a terminal based game. I am assuming X-Term like terminal. This means: I can use the X-Term control codes to clear and move around the screen. I can use tcsetattr functions to make standard input none buffered (I think). I know this game loop runs as basically a busy wait. I wi...

The story had three schools of magic, fire, earth/healing and storm. Each was controlled by a god. Fire and storm were guys while the other was a girl. These gods could possess humans which would allow the human to wield great magic. If I recall correctly, the main character (MC) was a young male...

I wrote some (humorous) poetry that uses a known song as a pattern.

I see different answers everywhere. Intuitively, I would think if residuals are autocorrelated then there is some information that you are not incorporating into your model and is a sign of a biased fit. However, I see sources saying it is not biased, but not the "best" estimate. What is the answ...

Consider the polynomial $g(x)=x^4+x^3+x^2+x+1 \in \mathbb{F}_3[x]$. It's possible to show that $g$ is irreducible in $\mathbb{F}_3$. If we let $\alpha$ be a root of $g$, then $\alpha^4+\alpha^3+\alpha^2+\alpha+1=0$, and it can be shown from this that $\alpha^5=1$. There's an interesting result th...

It's probably straightforward, but I would like to see the proof of the identity: $g_{\mu\nu}g^{\nu\alpha}=\delta^\alpha_\mu$ In the book 'Spacetime and Geometry' by Caroll, this identity is the motivation for calling $g^{\mu\nu}$ the 'inverse' of the metric.
