accepted What is the relation between the representation the Higgs field transforms under, the types of couplings in the theory and Higgs/Coulomb branches?

Excellent answer, thanks @Diracology.

comment How to bring a stick to the ground using many people?
@DanielSank When you perform it by yourself its easy to move all your fingers down at the exact same time and speed. When separate people are doing it, one person moves down hoping the others will follow at the same speed but will probably lose contact as nobody else is expecting the motion. Losing contact means the rules are broken. As Fabrice says, you'd have to have almost impossible synchronization in order for everyone to move down in unison at the same exact speed and at the same exact time. The problem gets more diffcult with more people.

I agree with @FabriceNEYRET. As he explains in his answer below, it's not human behaviour that's the key here.

revised Sources that explain strings between two branes, where one brane ends on the other
Added an addendum as there cannot be NS5-D3 strings (or NS5-NS5 strings).

comment Sources that explain strings between two branes, where one brane ends on the other
Thanks for the comment @OON, it seems plausible to me! A cursory search hasn't returned anything about fundamental strings ending on NS5-branes. The source ["Strings 2001: Proceedings of the Strings 2001 Conference, Tata Institute of Fundamental Research, Mumbai, India, January 5-10, 2001" page 163] talks about how the theory on two NS5-branes are determined by D-branes stretched between the two, and the theory on a D-brane is determined by fundamental strings beginning and ending on it. I'll add a bit to my original question asking for a greater focus on D-branes ending on other D-branes.

Added a little more about what I wanted to know. Specifically, what are the field theory results?

Ah okay, glad I could help :)

comment Do we know if the human brain follows Moore's Law?
Did you mean to ask: `Is the human brain limited to further increases in neuron density the same way that we think circuits will be/are restricted to increases in wire density, due to the effects of quantum tunnelling?'

comment Do we know if the human brain follows Moore's Law?
I would say the answer is that we do know and that the human brain does not conform to Moore's Law. The law is about how the transistor density increases with time, with each new iteration of the circuit. Assuming there are features of the brain that we can identify as transistors, the human brain evolved over an extremely long time. Also I'm not sure how much the densities of neurons increased with time but I highly doubt the density of transistor-like structures doubled every two years as human evolution just doesn't work that quickly.

I should note: I've found plenty of sources explaining strings between intersecting branes, but in the brane configurations I've studied, strings between branes ending on another brane never seem to be mentioned. I guess this means they aren't permitted for some reason.

revised Fayet-Iliopolous Parameters from Separation of NS5-branes in $(x_{7}, x_{8}, x_{9})$: An ambiguity as to which gauge group the FI parameter belongs
Made the internet link go to the arXiv page rather than directly to the pdf, as I've been previously instructed to do so!
