As written, this feat has some undefined qualities and I’m interested in knowing more specific details. As of right now, I am unaware of any errata or comments from the devs’ that clarify.

Benefit(s): While using this style, if you have at least 1 point in your ki pool, you gain a +2 bonus on saves against fear effects, and the DC of Intimidate checks against you increases by 4. As a swift action, you can spend 1 point from your ki pool to empower your unarmed strikes. Creatures hit with your unarmed strikes must succeed at a Will save (DC = 10 + 1/2 your character level + your Wisdom modifier) or become shaken for a number of rounds equal to your Wisdom modifier. This is a mind-affecting fear effect.

I heave two questions about this feat. The first is, how long do your unarmed strikes stay empowered for? A single strike, a round, a minute, for as long as you maintain the style, longer?

Secondly, will hitting a creature multiple times cause an increase in severity of the fear condition? Most effects that cause fear will list specifically that they don’t, but there’s also the general no stacking rule, so I’m unsure.

## How to extract the domain of the definition of the interpolating function?

When calling the interpolated function without specifying the value of the argument, Mathematica displays its domain of the interpolation. How to extract it?

## SyntaxError : ‘return’ outside function [closed]

I’m getting SyntaxError: ‘return’ outside function from this piece of code.

## Using more than 6 kernels in ParallelTable function

I have the following code:

ParallelTable[  If[IntegerQ@Sqrt[80892036 + 17994 x (1 + x) (-5995 + 5998 x)], x,    Nothing], {x, 6694300, 31072325}]

It uses 6 kernels to compute the result. Is it possible to speed it further up, by for example using more kernels?

## Failed Re-Verification (Test Again) Function

It’s been a while, but i was wondering again if this could easily be implemented.
Just an option to re-verify Failed Re-verification list on that list popup.
A while ago I was planning to make a batch file to use to do SOMEthing. Can’t exactly recall what…
Maybe it was saving the verified list BEFORE manually running Re-Verify  links so that after re-verification, I could match to see which were removed, and place them back in Verified right before I manually re-verify next time,  to be checked again?
I think I did this mnaually but it lost the other data fields…
Looking on GSA posts; I know I did mention it here.

## Showing that the quotient function is primitive recursive

I’m asked to show that the quotient function is primitive recursive. I know that the operation of integer division $$div$$ is not total, as it is not defined when the denominator is zero, and a recursive function has to be total by definition.

So I could give a function $$div’$$ and define a value for the case that the denominator is zero: $$div'(x,y) = 0$$ if $$y = 0$$, otherwise $$div'(x,y) = div(x,y)$$. But this is still not primitive recursive because of $$div$$. How can I go about proving that the quotient function is actually primitive recursive? Should it somehow be built from scratch? Any help would be appreciated.

## Do any programming language function calls internally call Operating system APIs?

To list directory content in Python we use os.listdir(), In Java we use Files.list(new File(dirName).toPath()). Like this we use a lot of functions calls, eg: For Network connectivity, Print in screen, Save to files.

In all operating systems do these all language-specific function calls ultimately call OS APIs (In Windows I think it will be Win32 APIs)?

ANything we can do without call OS APIs?

## Find a threshold such that one function is always bigger than the other

Given the recursively defined function $$c$$, which I believe is a variant of the Péter-Ackermann function: $$c(m,n)=\begin{cases}0&\text{for }m=0\ n^2+n+1&\text{for }m = 1\text{ and }n\ge 0\ c(m-1, 1)&\text{for }m>1\text{ and }n=0\ c(m-1,c(m,n-1))&\text{for }m>1\text{ and }n>0\ \end{cases}$$

and the function $$d$$ that builds a “tower” of powers of $$2$$ of size $$n+2$$:

$$d(n) = \underbrace{2^{2^{.^{.^{.^{.^{2}}}}}}}_{\text{ n+2 }}$$

The inputs $$m$$ and $$n$$ are both natural numbers. I’m asked to find an $$x$$, such that for all numbers $$y \ge x$$, $$c(y,y) > d(y)$$.

I rewrote the two functions using Python in order to calculate some values:

c(m, n):     if m == 0:         return 0     else if m == 1 and n >= 0:         return n**2+n+1              # return n^2+n+1     else if m > 1 and n == 0:         return c(m-1, 1)     else if m > 1 and n > 0:         return c(m-1, c(m, n-1))
d(n):     exp_num = n-1     result = 2     while exp_num != -1:         result = result**2           # result = result^2         exp_num = exp_num - 1     final_result = 2**result         # final_result = 2^result     return final_result

Some inputs and outputs:

c(1, 1) = 3

c(2, 2) = 183

d(1) = 16

d(2) = 65536

d(3) = 115792089237316195423570985008687907853269984665640564039457584007913129639936

I believe the threshold is $$3$$, as c(3, 3) doesn’t seem to be realistically computable considering there are over 19K digit in A(4, 2) (where A is the Péter-Ackermann function). Unfortunately I have no idea how to prove this. Any help would be much appreciated.

## Can a subset of indexes of a partial recursive function be recursively enumerable but not recursive?

Consider an admissible numbering of partial recursive functions. Consider the set of indexes corresponding to some function $$\phi$$. It may be seen that this set is not recursively enumerable. Does this set contain a recursively enumerable non-recursive subset?
