## Do I need a Polish passport to travel to Poland from the U.S.A if I hold U.S and Polish citizenship

If I would want to travel to Poland from the U.S would I only need a U.S. passport or do I also need a Polish passport? I hold Polish and U.S. citizenship. If I can’t go to Poland without a Polish passport, would I be able to travel there with a person that does have a Polish passport?

## hold – Control evaluation for functional constraints

I’m trying to understand how to use Mathematica to find a solution subject to constraints, where one of the constraints is specified as a predicate function. But I don’t know how to control evaluation in order to use the predicate function as a condition.

Here’s the problem. I want to find three integers, $a$, $b$, and $c$, subject to these constraints:

- They sum to 70
- Each of the integer is greater than or equal to 15 and less than 30
- No digits from 1-9 appears twice if you consider all the digits in the squares of the integers.

So how do I approach this with Mathematica? I expect I can use `FindInstance`

to find values under a set of constraints.

I can express constraints 1 and 2 by setting variables equal to equations and inequalities:

```
eq = (a + b + c == 70);
cs = 15 <= a <= 30 && 15 <= b <= 30 && 15 <= c <= 30;
```

In order to express the third constraint, I have defined this predicate function, which takes a list of numbers and returns true when they do not re-use digits:

```
UniqueDigitsQ(xss_) := With(
{nonzeros = Select(Flatten(Map(IntegerDigits,xss)) ,#1!=0&)},
SortBy(Tally(nonzeros),Last)((-1,-1)) <2);
```

So I would like to be able to express the third constraint by saying:

```
cs2 = UniqueDigitsQ( {a^2,b^2,c^2} );
```

But this fails, because the predicate function cannot handle symbolic argument.

Is there a way to fix this problem by defining the function in such a way that it does not evaluate until the arguments are numeric? Or else, what is the right approach?

## Wacom ( inteso pro ) shift hold issue

Not sure what is causing this issue but on driver version 6.3.41-2 I did not experience this issue, that I did already noticed previously.

I decide to update to latest driver and now I have it again, it randomly seems that I’m adding the shift while using the pen causing multiple object selection.

May be just something in tablet configuration / options or is a BUG?

## unity – Hold to Jump higher by using UI button

There is a jump script (Hold to Jump higher) and it works correctly on PC.

```
var jumpclick = Input.GetButtonDown("Jump");
var jumpPressed = Input.GetButton("Jump");
if (jumpclick)
{
rb.velocity = Vector3.up * jumpVelocity;
}
if (rb.velocity.y < 0)
{
rb.velocity += Vector3.up * Physics.gravity.y * (fallSpeed - 1) * Time.deltaTime;
}
else if (rb.velocity.y > 0 && !jumpPressed)
{
//Debug.Log("Pressing");
rb.velocity += Vector3.up * Physics.gravity.y * (lowJumpSpeed - 1) * Time.deltaTime;
}
```

but I want to jump by using UI button.

I tried to change “Input” to the “CrossPlatformInputManager” and add Event Trigger components on Ui button (SetDownState, SetUpState).

```
var jumpclick = CrossPlatformInputManager.GetButtonDown("Jump"); //works
var jumpPressed = CrossPlatformInputManager.GetButton("Jump"); //not works
```

but * CrossPlatformInputManager.GetButton(“Jump”)* doesn’t work

## homotopy theory – Does lifting correspondence hold for principal bundles too?

Let $P$ be a (nontrivial) principal bundle over the base space $mathbb{R}^4$ and fibers diffeomorphic to $SU(3)$.

Also assume that $P$ is equipped with an Ehresmann connection.

Then, for for any two given points $x,y in mathbb{R}^4$, all paths that connect them are path-homotopic.

Does this imply that the horizontal lifts of all these paths onto $P$ that start at the same point are also path-homotopic? Or at least can I assert that all such horizontal lifts end at the same point?

## trading – Am I misunderstanding shorting a currency in which I hold collateral on?

I want to know if I misunderstanding shorting a currency in which I hold collateral on?

In my margin account I have 1 BTC

I short only 4 BTC on BTC/USD even though I am allowed up to 10x (The maintenance margin is that I must maintain)

The price raises 20%

Forget for the moment the interest on the 4 BTC I just borrowed…

I now have 20% more collateral? Thus I will never get liquidated for the price going up? Since my margin’s value goes up with the BTC? The unrealized loss is mitigated by the the upward value? (Meaning I will have always have the collateral to support the upward?)

Of course when it goes down (as it always does) Any collateral value I am losing is made up in Profit? (Of course I will always exit with a profit if the price goes down)
