Does the Shockley Ideal diode equation involve drift current?

I’ve encountered a contradiction in semiconductors. The ideal diode equation considers saturation current (the current when applied voltage is reverse biased to the diode). We know that this saturation current is due to drift. However, on the other hand, the derivation of the Schockly ideal diode equation assumes no drift current in the transport equation. […]

Sound Not Updating On Output Device Change for Certain Apps

I’m using Ubuntu 19.10 and currently the sound works…mostly. There’s been one annoying issue I’ve run into, however: whenever I change the device that the sound outputs from, certain apps don’t figure out that I changed the output device. Certain apps, on the other hand, do. Here’s a list of which apps I know about: […]

Why doesn’t infection with Clostridium Tetani immunize you?

What Immunity to COVID-19 Really Means – Scientific American It is less clear what those antibody tests mean for real life, however, because immunity functions on a continuum. With some pathogens, such as the varicella-zoster virus (which causes chicken pox), infection confers near-universal, long-lasting resistance. Natural infection with Clostridium tetani, the bacterium that causes tetanus, […]

Cybersource – How to Avoid Making Double Calls to Credit a Credit Card

I’m working on a C# project that is supposed to cancel/refund the charges to a customer’s card. As I understand it from the documentation, if the settlement has not yet been processed (via the once-a-day batch processing), there is a window of opportunity to void the capture. If the void-capture operation is successful, you should […]

Why has Notepad++ stopped actually going to the specified line, only marking it?

If I have Notepad++ running with no files opened, or if Notepad++ isn’t running, and I run the command: “path to notepad++.exe” “path to whatever.php” -n123 … it opens the whatever.php file in Notepad++ and marks line #123, but it doesn’t scroll to it. I have to manually scroll down to it, and then I […]

What *really* is the difference between relational and non-relational data?

Here is where I am at right now: I know that relational data, like that found in relational databases like MySQL or Postgres, is relational because there are relations between the tables. That is the reason why RDBMS have rigid schemas. On the other hand, NoSQL databases offer a looser schema but lose those relations. […]

Is there a natural intermediate version of PA?

Below, “logic” means “regular logic containing first-order logic” in the sense of Ebbinghaus/Flum/Thomas. Setup For a logic $\mathcal{L}$, let $\mathcal{PA}(\mathcal{L})$ be the set of $\mathcal{L}$-sentences in the language of arithmetic consisting of: the ordered semiring axioms, and for each $\mathcal{L}$-formula $\varphi(x,y_1,…,y_n)$ the induction instance $$\forall y_1,…,y_n[[\varphi(0,y_1,…,y_n)\wedge\forall x(\varphi(x,y_1,…,y_n)\rightarrow\varphi(x+1,y_1,…,y_n))]\rightarrow\forall x\varphi(x,y_1,…,y_n)].$$ (Note that even if the new logic […]
